Description

TECHNICAL FIELD

[0001] The present application relates to the field of sensor data acquisition, in particular to a sensor data acquisition system, a tester and a data collector. BACKGROUND

[0002] The sensor data acquisition system is widely used in the application scenarios of batch sensor data acquisition. For example, one application scenario is to collect the temperature of multiple positions in a space environment in the process of collecting the temperature of the space environment, and record the temperature; another application scenario is to monitor the temperature of a sterilization device (such as a sterilization oven) in the sterilization process of medical device manufacturing to meet the sterilization requirements; and another application scenario is to perform temperature verification at various stages of the drug manufacturing process to meet the requirements of drug quality.

[0003] At present, the sensor data acquisition system mostly sets a tester host and a data collector used in combination with the tester host. The data collector connects the sensor to obtain the relevant measurement parameters collected by the sensor, and the data collector is connected to the tester host to transmit the relevant measurement parameters collected by the sensor to the tester host. Among them, the sensor is used to be arranged in various medical, pharmaceutical and food processing applications to collect relevant measurement parameters (such as pressure, temperature, humidity, etc.).

[0004] The combination of the tester host and the data collector is usually that a slot is provided on the tester host and a matching plug is provided on the data collector. When the tester host and the data collector are combined, the plug is plugged into the slot to realize the connection of the tester host and the data collector and the data interaction through the plug and the slot.

[0005] However, the plug-in mode of the tester host and the data collector is easy to cause the data collector and the tester host to be separated when the tester host is moved or the data collector is touched, which affects the data interaction between the data collector and the tester host or causes the data collector to fall. SUMMARY

[0006] The embodiments of the present application provide a sensor data acquisition system, a tester and a data collector, which can reduce the risk of the data collector and the tester being separated caused by moving the tester or touching the data collector.

[0007] The embodiments of the present application adopt the following technical solutions:

[0008] A sensor data acquisition system, comprising a tester and a data collector;

[0009] Among them, the tester comprises a containing groove for containing the data collector inserted therein, and the data collector is configured to be externally inserted into the containing groove.

[0010] The accommodating slot is provided with at least one limiting mechanism, which is configured to sequentially clamp the data collector in a first position and a second position when the data collector is inserted into the accommodating slot along a first direction;

[0011] The accommodating slot is provided with a retractable elastic protruding end, which provides the data collector with an elastic force in a second direction opposite to the first direction when the data collector is clamped in the second position, so that the elastic protruding end ejects the data collector from the second position to the first position when the limiting mechanism releases the data collector from the second position.

[0012] A tester, comprising:

[0013] An accommodating slot is provided for accommodating an inserted data collector;

[0014] The accommodating slot is provided with at least one limiting mechanism, which is configured to sequentially clamp the data collector in a first position and a second position when the data collector is inserted into the accommodating slot along a first direction;

[0015] The accommodating slot is provided with a retractable elastic protruding end, which provides the data collector with an elastic force in a second direction opposite to the first direction when the data collector is clamped in the second position, so that the elastic protruding end ejects the data collector from the second position to the first position when the limiting mechanism releases the data collector from the second position.

[0016] A data collector, which is configured to:

[0017] Be capable of being inserted into an accommodating slot provided on a tester, and when inserted into the accommodating slot along a first direction, be sequentially clamped in a first position and a second position;

[0018] When clamped in the second position, be in contact with an elastic protruding end in the accommodating slot, and receive an elastic force provided by the elastic protruding end in a second direction opposite to the first direction, so that when the tester releases the data collector from the second position, the data collector is ejected from the second position to the first position.

[0019] Based on the technical scheme, the sensor data acquisition system, the tester and the data collector, the data collector is capable of being inserted into the accommodating groove from the outside, the limiting mechanism is arranged in the accommodating groove, the data collector is clamped in the first position and the second position in sequence when the data collector is inserted into the accommodating groove along the first direction, the elastic protruding end is arranged in the accommodating groove and is capable of being stretched and retracted, the elastic protruding end provides the data collector with the elastic force in the second direction opposite to the first direction when the data collector is clamped in the second position, and the elastic protruding end ejects the data collector from the second position to the first position when the limiting mechanism releases the data collector from the second position. Thus, the data collector is clamped in the tester, and the data collector is capable of being ejected conveniently. The risk that the data collector is separated from the tester due to the movement of the tester or the touch of the data collector is reduced.

[0020] It should be understood that the foregoing general description and the following detailed description are only exemplary and explanatory and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF DRAWINGS

[0050] The exemplary embodiments will be described in detail herein with reference to the attached drawings. In the following description, the same numbers are used to designate the same elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not meant to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the appended claims.

[0051] The "first" mentioned in the embodiments of the present application is only used as a name identifier, and does not represent the first in order. The same rule applies to "second" and the like.

[0052] Embodiment 1

[0053] The present embodiment provides a sensor data acquisition system, as shown in the figure, the sensor data acquisition system comprises a tester 100 and a data collector 200; Figure 1a

[0054] The tester 100 comprises a receiving slot 11 for receiving the data collector 200, and the data collector 200 is configured to be inserted into the receiving slot 11 from the outside of the tester 100;

[0055] The receiving slot 11 is provided with at least one limiting mechanism 12, which is configured to sequentially clamp the data collector 200 in a first position as shown in the figure and a second position as shown in the figure when the data collector 200 is inserted into the receiving slot 11 along a first direction 300 as shown in the figure. Figure 1a Figure 1b Figure 1c

[0056] As​​​​Figure 1d As shown, the accommodating groove 11 is provided with a retractable elastic protruding end 13, which provides elastic force in a second direction 400 opposite to the first direction 300 to the data collector 200 when the data collector 200 is clamped in the second position, so that when the limiting mechanism 12 releases the data collector 200 from the second position, the elastic protruding end 13 will pop the data collector 200 from the second position to the first position. Figure 1c As shown, the data collector 200 is in the second position. Figure 1b As shown, the data collector 200 is in the first position.

[0057] It should be noted that, in order to more stably clamp the data collection device 200, two limiting mechanisms 12 are usually provided, and the symmetric arrangement of the two limiting mechanisms 12 is the best. The embodiment of the application illustrates the specific structure of a single limiting mechanism 12 and the implementation mode of clamping the data collector 200. When multiple limiting mechanisms 12 are provided, each limiting mechanism 12 can adopt the structure of the limiting mechanism 12 disclosed in the embodiment.

[0058] It should be understood that the above-mentioned first direction 300 is the direction in which the data collector 200 is inserted into the accommodating groove 11, and the above-mentioned second direction 400 is the direction in which the data collector 200 is pulled out of the accommodating groove 11.

[0059] Based on the above technical solution, the sensor data collection system is provided with an accommodating groove for accommodating the inserted data collector in the tester, a data collector capable of being inserted into the accommodating groove from the outside is constructed, and a limiting mechanism is arranged in the accommodating groove, so that when the data collector is inserted into the accommodating groove along the first direction, the data collector is clamped in the first position and the second position in turn, and a retractable elastic protruding end is arranged in the accommodating groove, so that when the data collector is clamped in the second position, the elastic protruding end provides elastic force in the second direction opposite to the first direction to the data collector, and when the limiting mechanism releases the data collector from the second position, the elastic protruding end pops the data collector from the second position to the first position. Thus, the data collector is clamped in the tester, and the data collector can be easily popped out. The risk of disengagement of the data collector from the tester caused by moving the tester or touching the data collector can be reduced.

[0060] In one embodiment, the clamping force in the first position is smaller than the clamping force in the second position, as shown in Figure 1b As shown, the data collector 200 can be manually pulled out when the data collector 200 is in the first position, as shown in Figure 1c As shown, the data collector 200 cannot be manually pulled out when the data collector 200 is in the second position.

[0061] In one embodiment, as shown in Figure 1d The limiting mechanism 12 includes an elastic limiting pin 121;

[0062] As shown in Figure 1e The side of the data collector 200 is provided with a first limiting slot 21 and a second limiting slot 22 matching the limiting pin, the depth of the first limiting slot 21 is less than the depth of the second limiting slot 22;

[0063] During the process of inserting the data collector 200 into the tester 100 along the first direction 300, the limiting pin 121 falls into the first limiting slot 21 to fix the data collector 200 in the first position, and the limiting pin 121 falls into the second limiting slot 22 to fix the data collector 200 in the second position.

[0064] In this embodiment, the first limiting slot 21 and the second limiting slot 22 are provided with different depths, the depth of the first limiting slot 21 is less than the depth of the second limiting slot 22, so that when the limiting pin 121 falls into the first limiting slot 21, a smaller fixing force is provided, which is convenient for manually pulling out the data collector 200; when the limiting pin 121 falls into the second limiting slot 22, a larger fixing force is provided, which prevents the data collector 200 from falling off. And when the limiting pin 121 falls into the second limiting slot 22, the data collector 200 is in the second position as shown in Figure 1c , which is not convenient for manually pulling out the data collector 200, thereby further reducing the risk of the data collector 200 deviating from the second position.

[0065] In one embodiment, as shown in Figure 1f The limiting pin 121 includes an angular protrusion (such as a triangle) for clamping the data collector, the angular protrusion has a first face opposite to the first direction 300 and a second face opposite to the first direction 300, the cross section of the first limiting slot 21 and the second limiting slot 22 matches the shape of the angular protrusion, and the slope of the first face is less than the slope of the second face.

[0066] In one embodiment, the limiting mechanism 12 includes a strip-shaped guide ridge 122 arranged along the first direction and the second direction 400;

[0067] The data collector 200 is provided with a strip-shaped guide slot 23 matching the guide ridge 122, the guide slot 23 cooperates with the guide ridge 122, so that the data collector 200 can be inserted into the accommodating slot 11 along the first direction 300 and separated from the accommodating slot 11 along the second direction 400.

[0068] In one embodiment, as shown in Figure 1e The first limiting slot 21 and the second limiting slot 22 are arranged in the guide slot 23, and the limiting pin 121 is arranged on the guide ridge 122.

[0069] In one embodiment, as shown in 1f, the limiting mechanism 12 comprises a pressing end 123, which is arranged at the edge of the accommodating groove 11, and the pressing end 123 is in contact with the limiting pin 121 through a connecting rod 124. The pressing end 123 is configured to, when the pressing end 123 is pressed, the connecting rod 124 drives the limiting pin 121 to disengage from the second limiting groove 22, and the data collector 200 is released.

[0070] In one embodiment, when the pressing end 123 is pressed along the first direction 300, the connecting rod 124 moves along the first direction, drives the limiting pin 121 to disengage from the second limiting groove 22, and the data collector 200 is released.

[0071] In one embodiment, the connecting rod 124 is provided with an elastic member 125, which provides a rebound force to the connecting rod 124 in the second direction 400. When the pressing end 123 is pressed along the first direction 300, the rebound force provided by the elastic member 125 rebounds the connecting rod 124 along the second direction 400, and drives the pressing end 123 to reset.

[0072] In one embodiment, the connecting rod 124 is provided with a first inclined surface, and the limiting pin 121 is provided with a second inclined surface opposite to the first inclined surface. The first inclined surface and the second inclined surface are in sliding contact, so that when the connecting rod 124 moves along the first direction 300, the contact area between the first inclined surface and the second inclined surface increases, drives the limiting pin 121 to disengage from the second limiting groove 22, and the data collector 300 is released.

[0073] In this embodiment, the data collector is popped out from the second position to the first position under the elastic force of the elastic protruding end 13, and in the first position, the user can manually pull out the data collector 200. It should be noted that in the first position, the limiting pin 121 is clamped in the first limiting groove 21 to fix the data collector 200, so that the data collector 200 can still be fixed in the accommodating cavity 11 before being pulled out, thereby preventing the data collector 200 from falling accidentally.

[0074] In one embodiment, the elastic protruding end 13 is in contact with the data collector 200 in the first position, and the elastic force provided by the elastic protruding end 13 gradually increases between the first position and the second position.

[0075] In one embodiment, as shown in Figure 1d Figure 1g The tester 100 is provided with a first contact end 14 connected to the processor of the tester 100, and the data collector 200 is provided with a second contact end 24 matched with the first contact end, and the second contact end 24 is connected to the processor of the data collector 200.

[0076] When the data collector 200 is clamped in the first position, the first contact end 14 is disengaged from the second contact end 24;

[0077] When the data collector 200 is clamped in the second position, the first contact end 14 is in contact with the second contact end 24 to establish an electrical connection, so that the tester 100 and the data collector 200 interact with each other based on the electrical connection, thereby realizing that the processor of the data collector 200 transmits the measurement data collected by at least one sensor connected to the data collector 200 to the tester 100, and the processor of the tester processes the measurement data collected by the at least one sensor.

[0078] In one embodiment, after the first contact end 14 is in contact with the second contact end 24, the first contact end can be integrated with the second contact end to follow the data collector 200 when the data collector 200 is clamped in the second position. This can also enable the data collector 200 to be slightly shaken in the accommodating groove 11 while maintaining the electrical connection with the tester 100.

[0079] In one embodiment, one of the first contact end 14 and the second contact end 24 includes a pin seat 142 provided with a pin 141, and the other of the first contact end 14 and the second contact end (not shown) is provided with a groove 141 matched with the pin 141. As shown, in this embodiment, the first contact end 14 is provided with the pin seat 142 provided with the pin 141, and the second contact end is provided with the groove 141 matched with the pin 141. Figure 1d

[0080] In one embodiment, the accommodating groove 11 includes first and second opposite side walls;

[0081] The limiting mechanism 12 is two, respectively arranged on the first and second side walls. Specifically, to facilitate operation, the two limiting mechanisms 12 are usually arranged symmetrically.

[0082] ​The sensor data acquisition system based on the above technical solution constructs a data acquisition device that can be inserted into the testing instrument through a receiving groove. A limiting mechanism in the receiving groove sequentially secures the data acquisition device to a first position and a second position when inserted along a first direction. A retractable elastic protrusion in the receiving groove provides a second-direction elastic force to the data acquisition device when it is secured in the second position. When the limiting mechanism releases the data acquisition device from the second position, the elastic protrusion ejects the data acquisition device from the second position to the first position. This effectively secures the data acquisition device to the testing instrument and facilitates its ejection, reducing the risk of the data acquisition device detaching from the testing instrument due to movement or contact.

[0083] Example 2

[0084] like Figure 1h As shown, the on-site temperature verification host includes a host body (tester 100), and an interaction module 200A is provided on the host body (tester 100). The interaction module 200A may include a touch screen and has both display and touch input functions. The host body has a main control module, which has processing and storage capabilities. Thus, it can process the temperature verification data collected by the multi-channel recorder on the one hand, and perform operations in response to the instructions of the interaction module on the other hand, such as setting temperature verification tasks. The interaction module and the main control module are electrically connected.

[0085] The main unit (tester 100) has a recorder mounting compartment 171 (accommodation slot 11) for detachably arranging a multi-channel recorder 700 (data acquisition unit 200). Unlike the temperature verification device, the multi-channel recorder has stronger and more temperature information measurement capabilities.

[0086] The recorder installation compartment 171 (accommodation groove 11) is provided with a recorder compartment opening at one end surface of the main body, and the circumferential profile of the recorder installation compartment 171 and the recorder compartment opening and the circumferential profile of the multi-channel recorder 700 are matched, so that the multi-channel recorder 700 passes through the recorder compartment opening and is at least partially located in the recorder installation compartment 171. In view of the arrangement of the interaction module 200A, in order to ensure that the display interface is large enough and the multi-channel recorder is configured conveniently, the interaction module 200A is generally arranged at the front end surface or the upper end surface of the main body, the recorder compartment opening is arranged at the end surface different from the interaction module 200A, and the recorder compartment opening is not arranged at the bottom surface of the main body. For example, in the present example, the interaction module 200A is arranged at the upper end surface of the main body, and the recorder compartment opening is arranged at the front end surface of the main body. In other schemes, the interaction module 200A is arranged at the upper end surface of the main body, and the recorder compartment opening can also be arranged at the left end surface, the right end surface or the rear end surface of the main body (although these ways are not the optimal design scheme). Alternatively, the interaction module 200A is arranged at the front end surface of the main body, and the recorder compartment opening can be arranged at the upper end surface, the left end surface, the right end surface or the rear end surface of the main body. It should be noted that the position of the recorder compartment opening is determined, and when there are multiple recorder installation compartments, the recorder compartment openings of the recorder installation compartments should be at the same end surface of the main body.

[0087] The host connection end 115 (second contact end 24) is arranged on one inner side surface of the recorder installation compartment 171. The inner side surface can be the inner side surface of the recorder installation compartment 171 opposite to the recorder compartment opening (for example, the rear side surface of the recorder installation compartment 171 in the present example), or other inner side surfaces of the recorder installation compartment 171. The host connection end 115 is electrically connected with the host control module 500.

[0088] The end of the multi-channel recorder 700 that is adapted to the host connecting end 115 is provided with a recorder connecting end 733 (the first contact end 14). The adaptation is reflected in the fact that the position of the recorder connecting end 733 corresponds to the position of the host connecting end 115. In the example shown in the figure, the host connecting end 115 is located in the middle of the rear side of the recorder mounting compartment 171, and the recorder connecting end 733 is also located in the middle of the rear end of the multi-channel recorder 700. The host connecting end 115 and the recorder connecting end 733 have a matching connection structure and communication protocol, so that when the multi-channel recorder 700 is adaptively arranged in the recorder mounting compartment 171, as shown in the example in the figure, the multi-channel recorder 700 is inserted into the recorder mounting compartment 171 as much as possible, and the rear end of the multi-channel recorder 700 is in contact or close enough to the rear end of the recorder mounting compartment 171. At this time, the host connecting end 115 and the recorder connecting end 733 are adaptively connected. Through this adaptive connection, the host body of the temperature verification device and the multi-channel recorder are in an integrated state in terms of structure and data relationship.

[0089] Further improvements can be made around the adaptive arrangement relationship between the multi-channel recorder 700 and the recorder mounting compartment 171. The inner side of the recorder mounting compartment is provided with a first locking mechanism, and the end of the multi-channel recorder is provided with a second locking mechanism that is adapted to the first locking mechanism. When the host connecting end and the recorder connecting end are adaptively connected, the first locking mechanism and the second locking mechanism are adaptively locked.

[0090] As shown in the example, Figure 2 The inner side of the recorder mounting compartment 171 (the accommodation groove 11) is provided with a first locking mechanism. Specifically, the first locking mechanism includes a first magnetic attraction member 1841 and a magnetic shielding sheet 1842. The first magnetic attraction member 1841 is fixedly arranged in the host body and exposed on the inner side of the recorder mounting compartment 171. There is a magnetic shielding cavity 1843 between the first magnetic attraction member 1841 and the internal space of the recorder mounting compartment 171. The magnetic shielding cavity 1843 is a flat cavity, and the magnetic shielding sheet 1842 is movably arranged in the magnetic shielding cavity 1843 and can move along the circumferential area of the magnetic shielding cavity 1843;

[0091] Specifically, the circumferential contour of the magnetic shielding cavity 1843 covers the first magnetic attraction member 1841, and the circumferential contour of the magnetic shielding sheet 1842 can also cover the first magnetic attraction member 1841. The circumferential contour of the magnetic shielding cavity 1843 is large enough to cover the magnetic shielding sheet 1842 that does not coincide with the first magnetic attraction member 1841 in addition to covering the first magnetic attraction member 1841;

[0092] The unlocking plate 1844 is exposed outside the main body, and the other end of the unlocking plate 1844 is fixed to the magnetic isolation sheet 1842. At this time, adjusting the one end of the unlocking plate 1844 outside the main body can drive the magnetic isolation sheet 1842 to move in the magnetic isolation cavity 1843.

[0093] The second locking mechanism is arranged at the end of the multi-channel recorder 700, and includes a second magnetic attraction member 784 fixed to the end of the multi-channel recorder 700. The fixed position of the second magnetic attraction member 784 corresponds to the fixed position of the first magnetic attraction member 1841, and the magnetic poles of the first magnetic attraction member 1841 and the second magnetic attraction member 784 are opposite.

[0094] When the multi-channel recorder 700 is located in the recorder mounting cavity 171, the first magnetic attraction member 1841 and the second magnetic attraction member 784 are opposite and face opposite directions. Further, preferably, the first magnetic attraction member 1841 is fixed to the inner side of the recorder mounting cavity 171 facing the recorder cavity. At this time, by means of the magnetic attraction force between the first magnetic attraction member 1841 and the second magnetic attraction member 784, the multi-channel recorder 700 is fixed in the recorder mounting cavity 171. At this time, if it is necessary to take out the multi-channel recorder 700, the unlocking plate 1844 is pushed to move the magnetic isolation sheet 1842 from other positions in the magnetic isolation cavity 1843 to the position between the first magnetic attraction member 1841 and the second magnetic attraction member 784. Due to the magnetic isolation effect of the magnetic isolation sheet 1842, the magnetic attraction force between the first magnetic attraction member 1841 and the second magnetic attraction member 784 can become very small. At this time, the multi-channel recorder 700 can be easily taken out from the recorder mounting cavity 171.

[0095] Further, as shown in FIG. 1, Figure 3 The recorder cavity is located at the front end of the recorder mounting cavity 171. The first locking mechanism includes left limiting elastic sheets 1851 arranged symmetrically on the left inner side of the recorder mounting cavity 171 and right limiting elastic sheets 1852 arranged on the right inner side of the recorder mounting cavity 171 (in other examples, the limiting elastic sheets can also be upper limiting elastic sheets arranged on the upper inner side and lower limiting elastic sheets arranged on the lower inner side. The limiting elastic sheets are preferably arranged in pairs and located on the inner side perpendicular to the opening direction of the recorder cavity). The first locking mechanism further includes limiting push rods 1853 linked with the left and right limiting elastic sheets.

[0096] The left limiting spring 1851 and the right limiting spring 1852 both extend along the front-rear direction (the relative movement direction of the multi-channel recorder 700 and the recorder mounting compartment 171), one end of the left limiting spring 1851 is fixedly arranged in the left inner side surface of the recorder mounting compartment 171, the other end of the left limiting spring 1851 is in contact with the limiting push rod 1853, and the left limiting spring 1851 is elastically deformed to protrude to the right under the pushing of the limiting push rod 1853; and one end of the right limiting spring 1852 is fixedly arranged in the right inner side surface of the recorder mounting compartment 171, the other end of the right limiting spring 1852 is in contact with the limiting push rod 1853, and the right limiting spring 1852 is elastically deformed to protrude to the left under the pushing of the limiting push rod 1853.

[0097] The limiting push rod 1853 is movably arranged in the push rod chamber 1854 near the recorder mounting compartment 171, the push rod chamber 1854 extends along the front-rear direction, the rear end of the push rod chamber 1854 extends to the left limiting spring 1851 and the right limiting spring 1852, and the front end of the push rod chamber 1854 extends to the front end surface of the main body, so that the limiting push rod 1853 can move along the front-rear direction.

[0098] The length of the limiting push rod 1853 is l_1, the natural extension length (i.e. the length without elastic deformation) of the limiting spring (1851, 1852) is l_2, the length of the limiting spring (1851, 1852) when a larger elastic deformation is generated is l_3, and the distance between the fixed end of the limiting spring (1851, 1852) and the front end of the main body is l_4, and in a preferred design, l_1+l_2>l_4=l_1+l_3.

[0099] Further, the push rod stopper 1855 is arranged on the limiting push rod 1853, and the chamber stopper 1856 is arranged in the push rod chamber 1854, the chamber stopper 1856 is located between the front end of the main body and the push rod stopper 1855, the distance between the push rod stopper 1855 and the rear end (i.e. the end in contact with the limiting spring) of the limiting push rod 1853 is l_5, and the distance between the chamber stopper 1856 and the fixed end of the limiting spring (1851, 1852) is l_6, and l_5+l_2 is slightly greater than l_6.

[0100] Further, the limiting auxiliary baffle 1857 is arranged at the front end of the push rod chamber 1854, and the limiting auxiliary baffle 1857 can limit the limiting push rod 1853 in the push rod chamber 1854 when closed.

[0101] Furthermore, the multichannel recorder 700 is symmetrically provided with limiting arc surfaces 785 (i.e., the second locking mechanism) at the left and right ends. The position of the limiting arc surfaces 785 corresponds to the limiting springs (1851, 1852). The limiting arc surface 785 on the left side is recessed to the right, and the limiting arc surface 785 on the right side is recessed to the left. The shape of the recess matches the shape of the protruding elastic deformation of the limiting springs (1851, 1852).

[0102] At work, located in Figure 3 Taking the relevant components on the left side as an example, when the multi-channel recorder 700 is installed in the recorder mounting compartment 171, the limiting push rod 1853 is fully pushed into the push rod chamber 1854 and the limiting auxiliary baffle 1857 is closed. At this time, due to the pushing of the limiting push rod 1853, the limiting spring pieces (1851, 1852) undergo a large elastic deformation, and the deformed protruding part of the limiting spring pieces (1851, 1852) protrudes into the limiting arc surface 785 on the multi-channel recorder 700 and fits and clamps, thereby fixing the multi-channel recorder 700 in the recorder mounting compartment 171.

[0103] At work, located in Figure 3 Taking the relevant components on the right side as an example, if it is necessary to unlock the first locking mechanism and the second locking mechanism, the limit auxiliary baffle 1857 is opened. At this time, under the influence of the elastic force of the limit springs (1851, 1852), the limit push rod 1853 pops out of the push rod chamber 1854 until the push rod stop 1855 and the chamber stop 1856 come into contact. Since l_5+l_2 is slightly greater than l_6, the elastic deformation of the limit springs (1851, 1852) is very small, so that the limit springs (1851, 1852) and the limit arc surface 785 are released from the jamming state. At this time, the multi-channel recorder 700 can be taken out from the recorder installation compartment 171 relatively easily. At the same time, since the elastic deformation of the limit springs (1851, 1852) still exists, it can still be ensured that the limit springs (1851, 1852) undergo elastic deformation in the predetermined direction during subsequent fitting and locking.

[0104] Unlike the aforementioned fixing method, the first locking mechanism and the second locking mechanism can be fixed by a combination of a locking block and a locking groove. Specifically, one of the first locking mechanism and the second locking mechanism includes a locking block and the other includes a locking groove. The protruding structure of the locking block and the recessed structure of the locking groove cooperate to allow the locking block to be at least partially inserted into the locking groove, and the insertion direction is perpendicular to the relative movement direction of the multi-channel recorder and the recorder mounting compartment.

[0105] For example, such as Figure 4 and Figure 5As shown, the recorder mounting compartment 171 is provided with lock block movable blind holes 1811 symmetrically arranged on the left and right inner sides, the lock block movable blind holes 1811 extend in the left-right direction, the opening of the lock block movable blind hole 1811 on the left side faces right, and the opening of the lock block movable blind hole 1811 on the right side faces left. The recorder compartment opening is located on the upper end surface of the recorder mounting compartment 171, that is, the multi-channel recorder 700 and the recorder mounting compartment 171 can move relative to each other in the up-down direction.

[0106] The lock block 182 is movably arranged in the lock block movable blind hole 1811, the circumferential profile of the lock block 182 matches the circumferential profile of the lock block movable blind hole 1811, so that the lock block 182 is limited to move in the front-rear direction and the up-down direction by the lock block movable blind hole 1811. The axial length of the lock block movable blind hole 1811 (i.e. the distance from the bottom of the blind hole to the opening of the blind hole) is greater than the axial length of the lock block 182, so that the lock block 182 can move axially in the lock block movable blind hole 1811.

[0107] The lock block movable blind hole 1811 is provided with a lock block elastic element 1824, which is located between the bottom of the lock block movable blind hole 1811 and the lock block 182. The elastic force direction of the lock block elastic element 1824 is perpendicular to the opening direction of the lock block movable blind hole. Under the influence of the elastic force, the lock block 182 is at least partially ejected out of the lock block movable blind hole 1811 without being blocked at the opening of the lock block movable blind hole 1811.

[0108] The lock block 182 can be further optimized in design, and the end portion of the lock block 182 exposed outside the lock block movable blind hole 1811 (for example, for the lock block 182 on the left side, the end portion is the right end portion of the lock block 182) is provided with a certain slope surface.

[0109] The concept of the slope surface is that, when the lock block 182 is fully or partially ejected out of the lock block movable blind hole 1811 under the influence of the elastic force, if the opening of the lock block movable blind hole 1811 is taken as a reference plane, the exposed portion of the lock block 182 forms a slope or protrusion relative to the reference plane, thereby playing a locking and limiting role.

[0110] Specifically, the locking block 182 has a first limiting slope 1821 and a second limiting slope 1822 at its end. The first limiting slope 1821 is located on the side of the locking block 182 facing the recorder compartment opening (since it is a slope, this orientation is not a direct facing orientation but rather has a certain angle). In this example, since the locking block 182 is located below the recorder compartment opening, taking the locking block located on the left as an example, the extension direction of its first limiting slope 1821 extends from the upper left (equivalent to the bottom of the slope) to the lower right (equivalent to the top of the slope). The first limiting slope 1821 and the reference plane near the recorder compartment opening form an acute angle; the second limiting slope 1822 is set on the side of the locking block 182 facing away from the recorder compartment opening. In this example, taking the locking block located on the left as an example, the extension direction of its second limiting slope 1822 diffracts from the lower left (equivalent to the bottom of the slope) to the upper right (equivalent to the top of the slope). The second limiting slope 1822 and the reference plane near the recorder compartment opening form an acute or right angle; the slope angle of the first limiting slope 1821 is less than or equal to the slope angle of the second limiting slope 1822.

[0111] It should be noted that if the locking block 182 is equipped with an unlocking mechanism, the slope angle of the second limiting slope 1822 can be a right angle; if the locking block 182 is not equipped with an unlocking mechanism, the slope angle of the second limiting slope 1822 is an acute angle.

[0112] To make the first locking mechanism, including the aforementioned locking block 182 and its related structures, as convenient as possible during operation, an unlocking mechanism can also be designed for further optimization.

[0113] This example is still as follows Figure 4 and Figure 5 As shown, the main unit has an unlocking push rod 183 near the recorder mounting compartment 171. One end of the unlocking push rod 183 protrudes from the main unit (including its surface), allowing the operator to operate the unlocking push rod 183. The other end of the unlocking push rod 183 contacts the locking block 182, so that force applied to the unlocking push rod 183 can act on the locking block 182. When one end of the unlocking push rod 183 (i.e., the end protruding from the main unit) is subjected to force, the unlocking push rod 183 undergoes an unlocking movement. The other end of the unlocking push rod 183 will drive the locking block 182 to move towards the bottom of the locking block movable blind hole 1811, thereby achieving unlocking.

[0114] The extension direction of the unlocking push rod 183 is perpendicular to the moving direction of the lock block 182. Specifically, the main body is provided with an unlocking cavity extending in the up-down direction near the recorder installation compartment 171. The peripheral contour of the unlocking cavity matches the peripheral contour of the unlocking push rod 183. The axial direction (i.e., the up-down direction) of the unlocking cavity can exactly accommodate the unlocking push rod 183, so that the unlocking push rod 183 can move up and down in the unlocking cavity. The upper end of the unlocking cavity extends to the upper end surface of the main body, and the lower end of the unlocking cavity extends to the upper side of the lock block moving blind hole 1811.

[0115] The unlocking push rod 183 extends in the up-down direction. The upper end of the unlocking push rod 183 extends to the surface of the main body, so that the operator can realize the unlocking operation by pressing the unlocking push rod 183 downward. The lower end of the unlocking push rod 183 extends downward to the upper end surface of the lock block 182. Taking the lock block 182 on the left side as an example, since the right end (the first limiting slope surface 1821 and the second limiting slope surface 1822) is used to adapt to the locking of the second locking mechanism, the lower end of the unlocking push rod 183 is in contact with the left end of the lock block 182 (avoiding the end part provided with the limiting slope surface, so it can also be the middle part).

[0116] The downward pushing force and displacement of the unlocking push rod 183 can be converted into the leftward pushing force and displacement of the lock block 182. Therefore, taking the lock block 182 on the left side as an example, the lock block 182 is provided with a protruding part in the upward direction at the position of the left end in the downward direction. The protruding part forms an unlocking slope surface 1823. The direction of the unlocking slope surface 1823 is the same as that of the first limiting slope surface 1821. The slope angles (i.e., the angles with the aforementioned reference plane) of the two can be the same or different. Correspondingly, the unlocking push rod 183 is provided with an unlocking reverse slope surface 1832 at the position in contact with the lock block 182. The unlocking reverse slope surface 1832 and the unlocking slope surface 1823 have exactly opposite directions. The unlocking reverse slope surface 1832 and the unlocking slope surface 1823 at least partially contact.

[0117] The unlocking push rod 183 and the lock block 182 are linked to switch the first locking mechanism between the locked state and the unlocked state.

[0118] The locked state is as follows. Figure 4As shown, taking the unlocking push rod 183 and locking block 182 located on the left as an example, the unlocking push rod 183 is located in a relatively high position, the unlocking reverse slope 1832 is also located in a relatively high position, the position of the locking block 182 in the vertical direction remains unchanged, and the unlocking reverse slope 1832 extends from the lower right to the upper left. Therefore, only the lower and right part of the unlocking reverse slope 1832 contacts the upper and left part of the unlocking slope 1823. Affected by the elastic force of the locking block elastic element 1824, the locking block 182 has a tendency to move to the right. At the same time, based on the aforementioned position of the unlocking reverse slope 1832, the locking block 182 can move to the right and protrude completely or at least partially out of the locking block movable blind hole 1811, thereby adapting and locking with the second locking mechanism on the multi-channel recorder 700 located in the recorder mounting compartment 171.

[0119] Unlocked state, such as Figure 5 As shown, taking the unlocking push rod 183 and locking block 182 located on the left as an example, the unlocking push rod 183 is located in a relatively low position, and the unlocking reverse slope 1832 is also located in a relatively low position. The position of the locking block 182 in the vertical direction remains unchanged. At this time, the part of the upper and left side of the locking block 182 is in contact with the part of the unlocking reverse slope 1832 in the upper and left side. Since the locking block 182 cannot move in the vertical direction, in order to ensure that the unlocking slope 1823 of the locking block 182 can still make normal contact with the unlocking reverse slope 1832, the locking block 182 overcomes the elastic force of the locking block elastic element 1824 and moves to the left, so that the locking block 2 is completely or mostly located in the locking block movable blind hole 1811, thereby disengaging from the second locking mechanism on the multi-channel recorder 700 and realizing unlocking.

[0120] Considering user operating habits between locked and unlocked states, it is preferable that the device is always in the locked state when there is no additional operation, and is only in the unlocked state when operation is required. Therefore, an unlocking elastic element 1831 is set in conjunction with the unlocking push rod 183. Specifically, the unlocking elastic element 1831 is set between the unlocking push rod 183 and the main body. The extension direction of the unlocking elastic element 1831 and the unlocking push rod 183 is the same, and the elastic force direction of the unlocking elastic element 1831 is opposite to the unlocking movement direction of the unlocking push rod 183.

[0121] In this example, protrusions are provided in the unlocking cavity and on the unlocking push rod 183, and the unlocking elastic element 1831 is located between the two protrusions. The elastic force of the unlocking elastic element 1831 is upward. In the non-unlocked state (including the locked state), driven by the elastic force of the unlocking elastic element 1831, the unlocking push rod 183 is located in a higher position.

[0122] If the axial length of the multi-channel recorder 700 is equal to, less than, or slightly greater than the axial length of the recorder mounting compartment 171 (as in this example) Figure 4 and Figure 5In this case, when the multi-channel recorder 700 is inserted into the recorder mounting chamber 171, the multi-channel recorder 700 has no or only a very small exposed part outside the recorder mounting chamber 171, which is not conducive to extraction (because the circumferential profile of the multi-channel recorder 700 matches the circumferential profile of the recorder mounting chamber 171), and in the other case, based on the aforementioned unlocking design, when the unlocking state is entered, a pushing force needs to be applied to the unlocking push rod 183, and at least two or three forces need to be applied (i.e., one or two pushing forces are applied to the unlocking push rod 183, and one force is applied to the multi-channel recorder 700 for extraction), which is difficult for a user to operate from the perspective of ergonomics. Therefore, the recorder mounting chamber 171 is provided with a recorder ejection mechanism 173 on the inner surface opposite the recorder chamber opening. The recorder ejection mechanism 173 at least partially protrudes from the inner surface of the recorder mounting chamber 171, and the elastic force direction thereof is directly opposite the recorder chamber opening.

[0123] As in the present example, the recorder ejection mechanism 173 is arranged on the lower end surface of the recorder mounting chamber 171 and protrudes into the recorder mounting chamber 171. The recorder ejection mechanism 173 is provided with an elastic member (e.g., a spring) inside and the elastic force direction thereof is upward.

[0124] In the locked state, due to the adaptive locking between the first locking mechanism (including the aforementioned locking block 182) and the second locking mechanism, the elastic force of the recorder ejection mechanism 173 is relatively small and cannot overcome the force of the aforementioned adaptive locking. Therefore, it can be ensured that the multi-channel recorder 700 is still fixedly arranged in the recorder mounting chamber 171.

[0125] In the unlocked state, the locking block 182 and the second locking mechanism are disengaged. At this time, the elastic force of the recorder ejection mechanism 173 becomes the main force acting on the multi-channel recorder 700, which will cause the multi-channel recorder 700 to move upward and at least partially expose outside the recorder mounting chamber 171. At the same time, because the multi-channel recorder 700 has moved upward, even if the pushing force applied to the unlocking push rod 183 is stopped at this time, the locking block 182 and the second locking mechanism will not be in the locked state because the positions of the locking block 182 and the second locking mechanism no longer correspond, so that the multi-channel recorder 700 can be easily taken out.

[0126] In this embodiment, a multi-channel recorder configured in the aforementioned recorder installation compartment 171 is provided, which comprises a recorder body, one end face of the recorder body is provided with a recorder interaction board, the other end of the recorder body is provided with a plurality of measurement signal connection ends, the recorder body is provided with a recorder main control board, the recorder main control board is electrically connected with the recorder interaction board, the recorder connection end and each measurement signal connection end, the end where the measurement signal connection end is located corresponds to the recorder compartment opening, when the multi-channel recorder is located in the recorder installation compartment, the measurement signal connection end is exposed near the recorder compartment opening or outside the recorder installation compartment through the recorder compartment opening, at least one end of the recorder body is provided with a second locking mechanism for cooperating with the first locking mechanism in the recorder installation compartment, when the host connection end and the recorder connection end are adaptively connected, the first locking mechanism and the second locking mechanism are adaptively locked.

[0127] As shown in the example, Figure 2 As an example, the recorder installation compartment 171 contained in the temperature verification device shown in the example is taken as an example, the recorder compartment opening is provided on the front end face of the host body, the recorder installation compartment 171 extends axially along the front-rear direction, and the upper end face of the multi-channel recorder 700 is provided with the recorder interaction board 720, the front end of the multi-channel recorder is provided with a plurality of measurement signal connection ends 743, the middle part of the rear end of the multi-channel recorder is provided with the recorder connection end 733, and the circumferential contour of the multi-channel recorder (i.e. the contour surrounded by the upper and lower and left and right edges) cooperates with the inner contour of the recorder installation compartment 171 and the recorder compartment opening, so that the multi-channel recorder 700 can be inserted into the recorder installation compartment 171 from front to back, when the multi-channel recorder 700 is inserted as far as possible, the rear end face of the multi-channel recorder 700 is in contact with the rear side face of the recorder installation compartment 171, and the recorder connection end 733 and the host connection end 115 are adaptively connected;

[0128] In combination with Figure 2 As an example, on the rear end face of the recorder body, the second magnetic attraction member 784 is provided in cooperation with the first locking mechanism, and the position of the second magnetic attraction member 784 is opposite to the first magnetic attraction member 1841.

[0129] As another example, as shown in the example, Figure 3 As an example, the recorder installation compartment 171 contained in the temperature verification device related to the example is taken as an example, the limiting arc surface 785 (i.e. the second locking mechanism) is symmetrically provided on the left end and the right end of the multi-channel recorder 700, the position of the limiting arc surface 785 corresponds to the limiting elastic sheet (1851, 1852), the limiting arc surface 785 on the left side is recessed to the right, the limiting arc surface 785 on the right side is recessed to the left, and the recessed shape cooperates with the convex elastic deformation shape of the limiting elastic sheet (1851, 1852).

[0130] As another example, as shown in the example, Figure 4 and Figure 5For example, the recorder installation compartment 171 of the temperature verification device of the related example is provided with a second locking mechanism including a locking slot on the left and right sides of the multi-channel recorder symmetrically, and the locking slot can be matched with the locking block in the Figure 4 and Figure 5 ;

[0131] Specifically, the second locking mechanism includes a first locking slot 781, and the position of the first locking slot 781 on the multi-channel recorder corresponds to the position of the locking block 182 on the recorder installation compartment 171, that is, when the multi-channel recorder 700 is inserted into the recorder installation compartment 171 as much as possible, the slot direction of the first locking slot 781 and the protrusion direction of the locking block 182 are opposite to each other.

[0132] Further, the structure of the first locking slot 781 and the protruding part of the locking block 182 is matched, and for example, the first locking slot 781 and the locking block 182 on the left side, the right end of the locking block 182 is provided with a first limiting slope surface 1821 and a second limiting slope surface 1822, and correspondingly, the first locking slot 781 extending from the slot bottom to the slot opening also includes a first limiting groove surface 7811 and a second limiting groove surface 7812, wherein the first limiting groove surface 7811 and the first limiting slope surface 1821 are matched correspondingly, and the second limiting groove surface 7812 and the second limiting slope surface 1822 are matched correspondingly, when the locking block 182 and the first locking slot 781 are matched and closely fitted, the first limiting groove surface 7811 and the first limiting slope surface 1821 are all or at least most closely fitted, and the second limiting groove surface 7812 and the second limiting slope surface 1822 are all or at least most closely fitted, and the first locking slot 781 has a certain depth, so that the locking block 182 is difficult to move out of the first locking slot 781, thereby achieving the matching and fixing effect between the multi-channel recorder 700 and the recorder installation compartment 171.

[0133] Further improvement, in particular in combination with the aforementioned recorder ejection mechanism 173, the second locking mechanism further includes a second locking slot 782, and the structure of the second locking slot 782 is similar to that of the first locking slot 781, and the difference between the two is that the depth of the first locking slot 781 is larger, so that the first limiting slope surface 1821 and the second limiting slope surface 1822 can be all or at least most of them fall into the first locking slot 781, and the depth of the second locking slot 782 is smaller, and when the locking block 182 is inserted into the second locking slot 782, the first limiting slope surface 1821 and the second limiting slope surface 1822 only have a small part fall into the second locking slot 782;

[0134] The position of the second locking slot 782 is between the first locking slot 781 and the lower end surface of the multi-channel recorder 700 (that is, the end surface where the measurement signal connection end 743 is located is the upper end surface);

[0135] When working, the lock block 182 is inserted into the first lock slot 781, and when unlocking, the lock block 182 and the first lock slot 781 are still in the relative position at the moment of pushing the unlocking push rod 183. Due to the pushing of the unlocking push rod 183, the lock block 182 is retracted into the lock block movable blind hole 1811, the lock block 182 and the first lock slot 781 are out of contact, the adaptive locking relationship between the first locking mechanism and the second locking mechanism is released, and the multi-channel recorder 700 moves upward under the elastic force of the recorder ejection mechanism 173. The unlocking action is completed, and the multi-channel recorder 700 continues to move upward until the lock block 182 falls into the second lock slot 782. At this time, since the second lock slot 782 also has a certain depth, it can prevent the multi-channel recorder 700 from continuing to move upward. At the same time, since the adaptive locking force between the second lock slot 782 and the lock block 182 is small, when a larger extraction force is applied, the locking can be directly released, and the multi-channel recorder 700 can be completely taken out from the recorder mounting bin 171.

[0136] The cooperation relationship between the aforementioned lock block 182, unlocking push rod 183, first lock slot 781, second lock slot 782 and recorder ejection mechanism 173 has the following technical advantages:

[0137] With the addition of the recorder ejection mechanism 173, it is possible that after unlocking, the multi-channel recorder 700 is completely ejected, which may cause the operator to not catch the multi-channel recorder 700 in time, and further cause the device to be bumped;

[0138] In the foregoing scheme, combined with the design of the second lock slot 782, an "intermediate state" can be set between complete locking and complete removal. In the "intermediate state", the multi-channel recorder 700 can be easily removed, and direct complete ejection can be prevented.

[0139] In the optimization technical scheme, the host connection end 115 is arranged on the inner side of the recorder mounting bin, and the inner side is opposite to the recorder bin opening. Based on this optimization technical scheme, the host connection end 115 is a plug-in end, and the plug-in direction is directly opposite to the recorder bin opening.

[0140] Further optimizing the foregoing technical solutions, the host connecting end 115 comprises a connecting end head 116, a connecting end limiting frame 117 and a connecting end positioning member 117. The circumferential profile of the connecting end limiting frame 117 is slightly larger than that of the connecting end head 116, so that the connecting end head 116 can move circumferentially within the connecting end limiting frame 117. The connecting end positioning member 117 comprises a positioning magnet and is fixed with the connecting end head 116. Correspondingly, the recorder connecting end 733 is provided with a corresponding positioning magnet. When the host connecting end 115 and the recorder connecting end 733 are directly connected, they gradually approach each other. The connecting end positioning member 117 is affected by the magnetic force and moves to the directly connected position, driving the connecting end head 116 to move to the directly connected position, thereby completing the adaptive connection.

[0141] It should be noted that the structures of the first locking mechanism and the second locking mechanism given in the embodiment can be replaced with each other, and the forms given in the foregoing examples are only relatively optimal forms.

[0142] The temperature verification device can also be provided with a temperature measurement module, which can be configured with temperature measurement electronic components such as a thermal resistance measurement circuit, a thermal electromotive force measurement circuit, a cold end environmental temperature measurement circuit, etc., thereby allowing the temperature measurement module to measure a small amount of thermal resistance, thermocouples or other temperature sensors;

[0143] In some comprehensive temperature field temperature verification host, it is possible to configure temperature measurement module and pressure measurement module (not excluded, it is possible to integrate the components of the two modules to exist as a whole module), it is also possible to configure humidity or other commonly used industrial measurement interfaces.

[0144] Embodiment 3

[0145] As shown in Figure 6 and Figure 7 The temperature verification host comprises an interaction module 200A, a communication module 300A, a temperature measurement module 400A, a host control module 500 and a battery module 600. In addition to the temperature verification host, a multi-channel recorder 700 is also provided.

[0146] The temperature verification host comprises a shell assembly 100A for adaptive installation of various modules. The shell assembly 100A comprises an upper shell 101, a left shell 103, a lower shell 102, a right shell 104, a middle partition plate 105, a rear shell 106, a first layered plate 1071 and a second layered plate 1072.

[0147] The upper shell 101, the left shell 103, the lower shell 102 and the right shell 104 enclose an installation cavity which is open in front and back;

[0148] The middle partition plate 105 is arranged at a front position inside the mounting cavity and is perpendicular (or substantially perpendicular) to the upper shell 101, the left shell 103, the lower shell 102 and the right shell 104, thereby dividing the mounting cavity into a smaller interactive mounting compartment 120 at the front and a larger rear chamber at the rear;

[0149] The upper shell 101, the left shell 103, the lower shell 102 and the right shell 104 can be fixed by welding or other means, or can be directly integrated during manufacturing. The middle partition plate 105 can be fixed by welding or other means to at least two of the upper shell 101, the left shell 103, the lower shell 102 and the right shell 104, thereby fixing the middle partition plate 105 in the mounting cavity.

[0150] The rear shell 106 is detachably arranged at the rear end face of the mounting cavity and is perpendicular (or substantially perpendicular) to the upper shell 101, the left shell 103, the lower shell 102 and the right shell 104, and is parallel (or substantially parallel) to the middle partition plate 105;

[0151] The first layered plate 1071 and the second layered plate 1072 are arranged on the side of the rear shell 106 facing the mounting cavity (i.e. the front end face of the rear shell 106). The rear end of the first layered plate 1071 is fixed at an upper position in the middle of the rear shell 106 and is parallel (or substantially parallel) to the upper shell 101. The rear end of the second layered plate 1072 is fixed at a lower position in the middle of the rear shell 106 (lower than the first layered plate 1071) and is parallel (or substantially parallel) to the upper shell 101. The distance between the first layered plate 1071 and the upper shell 101 is equal to the distance between the first layered plate 1071 and the second layered plate 1072, thereby dividing the rear chamber into a first recorder mounting compartment 171 in the upper part of the rear chamber, a second recorder mounting compartment 172 in the middle part of the rear chamber and a main control mounting cavity in the lower part of the rear chamber.

[0152] The first layered plate 1071 and the second layered plate 1072 are fixed on the rear shell 106 by welding or other means, or can be directly integrated during manufacturing. The rear shell 106 is detachably fixed (e.g. bolted) to the upper shell 101, the left shell 103, the lower shell 102 and the right shell 104, thereby allowing the rear shell 106 to be separated from the mounting cavity.

[0153] The width (i.e. the length in the left-right direction) of the interaction installation compartment 120 is the same as the width of the interaction module 200A, the height (i.e. the length in the up-down direction) of the interaction installation compartment 120 is the same as the height of the interaction module 200A, and the front-rear direction length of the interaction installation compartment 120 is slightly smaller than or equal to the front-rear direction length of the interaction module 200A, so that when the interaction module 200A is installed in the interaction installation compartment 120, at least part of the interaction module 200A is fixed in the interaction installation compartment 120, and based on the matching installation relationship between the interaction module 200A and the interaction installation compartment 120, the display and control interface of the interaction module 200A is located at the front end face thereof; since the interaction module 200A is independent in structure from other modules, the installation and dismounting process of the interaction module 200A will not affect other modules of the temperature verification host.

[0154] The upper end face of the upper shell 101 is fixed with a communication compartment plate 108, the lower end face of the communication compartment plate 108 is fixed with the upper shell 101 or the two are directly integrally formed, the communication compartment plate 108 and the upper shell 101 enclose a communication installation compartment 130, the communication installation compartment 130 is provided with a communication compartment opening at the upper end face thereof for installing or taking out a communication module 300A, the height of the communication installation compartment 130 is the same as the height of the communication module 300A, the front-rear direction length of the communication installation compartment 130 is equal to or greater than the front-rear direction length of the communication module 300A, the width of the communication installation compartment 130 is equal to or greater than the width of the communication module 300A, and the upper end face profile of the communication module 300A is the same as the profile of the communication compartment opening, so that after the communication module 300A passes through the communication compartment opening, it is just completely located in the communication installation compartment 130, the gap between the upper end face of the communication installation compartment 130 and the upper end face of the communication module 300A is extremely small or basically no gap, the communication module 300A and the communication installation compartment 130 are detachably fixed, so as to realize the structural modularization of the communication module 300A, and the installation and dismounting process of the communication module 300A will not affect other modules of the temperature verification host.

[0155] The lower part of the right shell 104 is provided with a temperature measuring cavity at a position corresponding to the main control mounting cavity 150, and the outer contour of the temperature measuring cavity is equal to or slightly smaller than the outer contour of the right end face of the temperature measuring module 400. The temperature measuring cavity extends to the left (i.e., towards the main control mounting cavity 150) and partially overlaps the main control mounting cavity 150 to form a temperature measuring mounting cavity 140. Specifically, the temperature measuring cavity extends to the left (i.e., towards the main control mounting cavity 150) and is distributed on the upper, lower, front and rear surfaces of the temperature measuring cavity plate. The temperature measuring cavity plate is fixed to the right shell 104, thereby forming a limiting and fixing of the temperature measuring module 400 in the upper, lower, front and rear dimensions. The right end of the main control module 500 is provided with a first temperature plug-in end 540, and the left end of the temperature measuring module 400 is provided with a second temperature plug-in end 410. The first temperature plug-in end 540 includes a slot structure, and the length of the slot structure in the front-rear and up-down directions is matched with the left end of the temperature measuring module 400, so that the left end of the temperature measuring module 400 can be inserted into the slot structure. The second temperature plug-in end 410 can be adaptively plugged into the first temperature plug-in end 540.

[0156] The temperature measuring module 400 is detachably fixed in the temperature measuring mounting cavity 140 and adaptively connected with the main control module 500. Therefore, as long as the configuration of the main control module 500 is completed, the installation or disassembly of the temperature measuring module 400 can be conveniently performed, and the installation or disassembly process will not affect other modules of the temperature verification host except the main control module 500. In the case where the main control module 500 has been installed, the plugging of the temperature measuring module 400 will not affect the main control module 500.

[0157] The second layered plate 1072, the lower shell 102, the left shell 103, the right shell 104, the middle partition plate 105 and the rear shell 106 surround the main control mounting cavity 150. The height of the main control mounting cavity 150 is the same as the height of the main control module 500. The front-rear direction length of the main control mounting cavity 150 is the same as the front-rear direction length of the main control module 500. The width of the main control mounting cavity is the same as the width of the main control module 500.

[0158] During installation, first, the lower shell 102, the left shell 103, the right shell 104 and the middle partition plate 105 are assembled or manufactured. Then, the main control module 500 is placed in the lower part of the rear cavity (i.e., at the preset position of the main control mounting cavity 150). After that, the rear shell 106 is detachably fixed with other shell components, thereby forming the main control mounting cavity 150 and achieving the detachable fixing of the main control module 500.

[0159] During disassembly, the rear shell 106 is disassembled, and the second layered plate 1072 is also separated from the temperature verification host along with the rear shell 106. At this time, the upper end face and the rear end face of the main control mounting cavity 150 are both open, and the main control module 500 can be very conveniently taken out of the main control mounting cavity 150.

[0160] The middle part of the lower shell 102 has a part of area recessed into the installation cavity to form a downward opening groove structure, which is the battery installation compartment 160. Specifically, the width of the battery installation compartment 160 is the same as the width of the battery module 600, the front-rear direction length of the battery installation compartment 160 is the same as the front-rear direction length of the battery module 600, and the height of the battery installation compartment 160 is the same as the height of the battery module 600, so that the battery installation compartment 160 can just accommodate the battery module 600, and the battery module 600 is detachably fixed in the battery installation compartment 160. At this time, the lower end surface of the battery module 600 is flush or substantially flush with the lower end surface of the lower shell 102 (leaving space for the installation of the cover plate), and the installation and disassembly process of the battery module 600 will not affect other modules of the temperature verification host.

[0161] The upper shell 101, the left shell 103, the right shell 104, the middle partition plate 105, the first layered plate 1071, and the rear shell 106 surround the first recorder installation compartment 171. In the present example, the front-rear direction length of the first recorder installation compartment 171 is substantially the same as the front-rear direction length of the multi-channel recorder 700 (the front-rear direction length of the first recorder installation compartment 171 is slightly longer), the width of the first recorder installation compartment 171 is substantially equal to or slightly larger than the width of the first recorder installation compartment 171 (leaving space to adapt to the fixation of the multi-channel recorder 700), and the height of the first recorder installation compartment 171 is substantially equal to or slightly larger than the height of the first recorder installation compartment 171, so that the multi-channel recorder 700 can be just placed into the first recorder installation compartment 171;

[0162] The inner contour of the second recorder installation compartment 172 is substantially the same as that of the first recorder installation compartment 171, so that the multi-channel recorder 700 can also be placed into the second recorder installation compartment 172;

[0163] When the multi-channel recorder 700 is placed in the first recorder mounting compartment 171 and / or the second recorder mounting compartment 172, at the same time, one multi-channel recorder 700 can only be placed in one recorder mounting compartment (171, 172) at the same time, and one recorder mounting compartment (171, 172) can only be placed in one multi-channel recorder 700. In the present example, the first recorder mounting compartment 171 and the second recorder mounting compartment 172 can be placed in the multi-channel recorder 700 at the same time, or only one recorder mounting compartment 171 can be placed in the multi-channel recorder 700, while the other is idle. When the multi-channel recorder 700 is placed in the recorder mounting compartment (171, 172), the temperature verification host and the multi-channel recorder 700 become a whole multi-channel temperature verification device. At this time, the multi-channel temperature verification device will have the functions of the temperature verification host and the multi-channel recorder 700 under field verification conditions. When the multi-channel recorder 700 is removed from the first recorder mounting compartment 171 and / or the second recorder mounting compartment 172, the temperature verification host and the multi-channel recorder 700 are independent of each other.

The bottom of the communication module 300A is provided with a second communication plug-in end 340 matched with the first communication plug-in end 112.

[0178] As shown in Figure 9 and Figure 10 The communication module 300A includes a communication module shell 310, a Bluetooth chip set 321, an NFC chip set 322, a communication circuit board 323, and an external antenna 330.

[0179] The communication module shell 310 encloses a closed or semi-closed cavity, and the Bluetooth chip set 321, the NFC chip set 322, and the communication circuit board 323 are fixedly arranged in the cavity. The communication circuit board 323 is signal connected with the Bluetooth chip set 321 and the NFC chip set 322, respectively.

[0180] The upper end surface of the communication module shell 310 is provided with an antenna extension end 311, and the antenna extension end 311 includes a metal column and an internal thread fixing structure. The Bluetooth chip set 321 includes a built-in antenna, and the built-in antenna of the Bluetooth chip set 321 is electrically connected with the metal column of the antenna extension end 311.

[0181] The upper end surface of the communication module shell 310 is further provided with an NFC adapting position 312. In this example, the NFC adapting position 312 is a slightly downward concave circular groove structure, and the NFC chip set 322 is fixedly arranged near the NFC adapting position 312.

[0182] The second communication plug-in end 340 is electrically connected with the communication circuit board 323 and is fixedly arranged at the lower end surface of the communication module 300A. The second communication plug-in end 340 is a plug-in structure, and the plug-in direction is downward.

[0183] The lower end of the external antenna 330 is provided with an antenna docking end 331 matched with the antenna extension end 311. Specifically, the antenna docking end 331 includes an external thread fixing structure and a metal column (or a metal sleeve). When the antenna extension end 311 and the antenna docking end 331 are threadedly connected, the two metal columns are in close contact, so that the external antenna 330 and the built-in antenna of the Bluetooth chip set 321 are electrically connected, and the antenna of the Bluetooth chip set 321 is extended for communication.

[0184] Further, if the internal thread fixing structure of the antenna extension end 311 is a metal material with good conductivity and is electrically connected with the metal column / the built-in antenna of the Bluetooth chip set 321, and the external thread fixing structure of the antenna docking end 331 is a metal material with good conductivity and is electrically connected with the metal column / the internal antenna part of the external antenna 330, then the metal column structure can be omitted in whole or in part.

[0185] The Bluetooth chipset 321 in this example can also be replaced by Zigbee or other wireless communication chipsets.

[0186] During operation, the communication module 300A is used to establish a wireless data connection channel with the submersible temperature module. Specifically:

[0187] If the submersible temperature module is used in a scenario with good wireless environment, then the submersible temperature module uses Bluetooth communication. Correspondingly, the communication module 300A in this example uses the built-in antenna of the Bluetooth chipset 321 to establish a data connection with the submersible temperature module.

[0188] If the submersible temperature module is used in a scenario with poor wireless environment, then the submersible temperature module uses Bluetooth communication. Correspondingly, the external antenna 330 and the communication module 300A are adapted and connected to enhance the communication capability of the communication module 300A, thereby enabling the communication module 300A and the submersible temperature module to establish a data connection.

[0189] If the submersible temperature module is used in a scenario with a shielded field (for example, the submersible temperature module is in a temperature chamber with a metal shell on the outside of the temperature chamber), the external antenna 330 and the communication module 300A are adapted and connected. The external antenna 330 is a flexible antenna, and one end of the external antenna 330 is placed in the shielded field, so that the communication module 300A and the submersible temperature module can establish a data connection.

[0190] If the submersible temperature module uses NFC communication (for example, if the submersible module has strong power consumption limitations), then placing the submersible temperature module on the NFC adapter bit 312 will enable the communication module 300A to establish a data connection with the submersible temperature module through the NFC chipset 322.

[0191] like Figure 11 As shown, the temperature measurement module 400A includes two thermocouple measuring terminals 421, two resistance temperature detector (RTD) measuring terminals 422, a measurement circuit board, and a second temperature plug-in terminal 410. The measurement circuit board is electrically connected to the thermocouple measuring terminals 421, the RTD measuring terminals 422, and the second temperature plug-in terminal 410, respectively. The second temperature plug-in terminal 410 is structurally adapted to the first temperature plug-in terminal 540 located in the main control module 500. The measurement circuit board measures the thermoelectric potential signal transmitted by the thermocouple measuring terminals 421 and / or the RTD signal transmitted by the RTD measuring terminals 422, converts them into digital signals, and then transmits the digital signals to the main control module 500 through the adapter electrical connection between the second temperature plug-in terminal 410 and the first temperature plug-in terminal 540.

[0192] This specific embodiment also provides a multi-channel recorder 700 that can work independently or in conjunction with the temperature verification host.

The measurement circuit board 752 is used for measuring thermocouple signals / thermistor signals and generating digital signals representing the measurement results. The recorder power module 760 comprises a built-in rechargeable battery. The recorder main control board 751, the recorder power module 760 and the measurement circuit board 752 are fixedly arranged in the middle recorder shell 712 in parallel (or nearly parallel) to each other, and the recorder main control board 751 is located above the recorder power module 760, and the measurement circuit board 752 is located below the recorder power module 760;

[0196] The general signal connector 741 is used for acquiring digital signals and specific types of analog signals (for example, 4-20 mA), and is located corresponding to the recorder main control board 751. The rear end surface of the middle recorder shell 712 is provided with a general connection hole, which is arranged in a horizontal row and has a hole diameter slightly smaller than the outer diameter of the general signal connector 741, so that the general signal connector 741 cannot completely pass through the general connection hole. In the case of the present embodiment, the hole diameter of the general connection hole is smaller than the outer diameter of the rear end surface of the general signal connector 741. The general signal connector 741 is fixedly arranged at the general connection hole and is located entirely in the cavity enclosed by the recorder housing 710;

[0197] The measurement signal connector 743 is used for acquiring thermistor signals and / or thermocouple signals, and is located corresponding to the measurement circuit board 752. The rear end surface of the middle recorder shell 712 is provided with a measurement connection hole, which is arranged in a horizontal row and has a hole diameter slightly smaller than, equal to or slightly larger than the measurement signal connector 743. The measurement signal connector 743 is fixedly arranged at the measurement connection hole;

[0198] The recorder plug-in end 733 is fixedly arranged on the front end surface of the middle recorder shell 712, and the connection position and connection type of the recorder plug-in end 733 are adapted to the host plug-in end (115, 116) in the recorder mounting compartment (171, 172) of the temperature verification host.

[0199] As shown inFigure 13 As shown in the figure, the wireless communication module 731 is fixed in the cavity surrounded by the upper shell 711, the middle shell 712 and the lower shell 713 of the recorder, and is electrically connected with the recorder main control board 751. The wireless communication module 731 includes a built-in antenna, which is electrically connected with the antenna extension end 732. The antenna extension end 732 is fixed on the rear end surface of the middle shell 712. The external antenna includes an antenna connecting end which is adapted to the antenna extension end 732.

[0200] The recorder main control board 751 is electrically connected with the recorder interaction board 720, the measurement circuit board 752, the plurality of general signal connectors 741, the plurality of measurement signal connectors 743, the recorder power module 760, the wireless communication module 731 and the recorder plug-in end 733, respectively.

[0201] As shown in the figure, in order to make the installation and maintenance of the general signal connectors 741 of the multi-channel recorder 700 more convenient, a detachable fixing structure without bolts / screws is provided in the embodiment. Specifically, the front end of the general signal connector 741 is provided with a signal processing board 742. The general signal connector 741 is electrically connected with the signal processing board 742. The signal processing board 742 processes the obtained signals (which may be a digital signal containing measurement information or a general analog signal such as 4-20mA). The recorder main control board 751 is electrically connected with the signal processing board 742 and obtains the processed digital signal from the signal processing board 742. Figure 14 Figure 15 As shown in the figure, in order to make the installation and maintenance of the general signal connectors 741 of the multi-channel recorder 700 more convenient, a detachable fixing structure without bolts / screws is provided in the embodiment. Specifically, the front end of the general signal connector 741 is provided with a signal processing board 742. The general signal connector 741 is electrically connected with the signal processing board 742. The signal processing board 742 processes the obtained signals (which may be a digital signal containing measurement information or a general analog signal such as 4-20mA). The recorder main control board 751 is electrically connected with the signal processing board 742 and obtains the processed digital signal from the signal processing board 742.

[0202] The connector fixing block 791 is vertically fixed inside the middle shell 712 of the recorder. The distance (L_4) between the connector fixing block 791 and the rear end surface of the middle shell 712 is greater than the sum of the length (L_1) of the general signal connector 741 in the front-rear direction and the thickness (L_3) of the signal processing board 742, i.e. L_4>L_1+L_3. Therefore, when the general signal connector 741 contacts the rear end surface of the middle shell 712, there is a distance between the connector fixing block 791 and the signal processing board 742. Considering the compactness of the equipment structure, the distance between the connector fixing block 791 and the signal processing board 742 should be small. At the same time, in order to avoid the connector fixing block 791 from touching the electronic elements on the signal processing board 742, the distance between the connector fixing block 791 and the signal processing board 742 should be greater than the protruding length of the electronic elements on the signal processing board 742.

[0203] ​The connector fixing plate 792 is used to fix the universal signal connector 741 in cooperation with the connector fixing block 791. The connector fixing plate 792 is provided with a plate protruding part 793 and a plate recessed part 794 on the side facing the signal processing plate 742. The plate protruding part 793 corresponds to the blank area (i.e. the area without electronic components) on the signal processing plate 742, and the plate recessed part 794 corresponds to the area on the signal processing plate 742 where electronic components are arranged. The thickness of the connector fixing plate 792 at the plate protruding part 793 should be equal to or slightly greater than the distance between the connector fixing block 791 and the signal processing plate 742 (preferably, the material of the connector fixing plate 792 has slight elasticity), and the thickness of the connector fixing plate 792 at the plate recessed part 794 and the total length of the protrusions of the electronic components on the signal processing plate 742 should be slightly less than the distance between the connector fixing block 791 and the signal processing plate 742, so that when the connector fixing plate 792 is inserted between the connector fixing block 791 and the signal processing plate 742, the connector fixing plate 792 is clamped at the plate protruding part 793 with the connector fixing block 791 and the signal processing plate 742 respectively, and the connector fixing plate 792 is not in contact with the signal processing plate 742 and the electronic components arranged thereon at the plate recessed part 794.

[0204] Further, in order to reduce the assembly and manufacturing difficulty, when designing the signal processing plate 742, the electronic components are concentrated in a certain area of the signal processing plate 742, and correspondingly, the plate protruding part 793 on the connector fixing plate 792 is located on the left and right sides of the plate recessed part 794.

[0205] When the thickness of the connector fixing plate 792 at the plate protruding part 793 is slightly greater than the distance between the connector fixing block 791 and the signal processing plate 742, the material of the connector fixing plate 792 has elasticity, the rear end of the recorder main control board 751 is located at a position flush with the rear end of the connector fixing block 791, or the rear end of the recorder main control board 751 is slightly behind the rear end of the connector fixing block 791, and the recorder main control board 751 is located near the connector fixing block 791, and the connector fixing plate 792 has sufficient length in the up-down direction to contact the recorder main control board 751.

[0206] The connector fixing plate 792 is provided with an anti-disengagement limiting groove 795 at the position where it contacts the recorder main control board 751, and the anti-disengagement limiting groove 795 is adapted to the upper end of the recorder main control board 751, so that when the connector fixing plate 792 contacts the recorder main control board 751, the recorder main control board 751 is inserted into the anti-disengagement limiting groove 795.

[0207] When working, firstly, the universal signal connector 741 with the signal processing board 742 is placed near the universal connection hole, and the universal signal connector 741 is aligned with the universal connection hole, the rear end of the universal signal connector 741 is in contact with the rear end of the recorder middle shell 712, secondly, the connector fixing plate 792 is inserted between the connector fixing block 791 and the signal processing board 742, and the plate recessed part 794 is corresponding to the area of the signal processing board 742 with electronic elements, and the plate protruding part 793 avoids the area of the signal processing board 742 with electronic elements, thirdly, the connector fixing plate 792 is inserted to a sufficient depth, so that the recorder main control board 751 is corresponding to the position of the anti-disengagement limiting groove 795, at this time, affected by the elastic force of the connector fixing plate 792, the recorder main control board 751 is embedded in the anti-disengagement limiting groove 795;

[0208] After the foregoing configuration is completed, since the connector fixing block 791 and the connector fixing plate 792 cooperate, the universal signal connector 741 with the signal processing board 742 is clamped on one side, the other side of the universal signal connector 741 is in close contact with the recorder middle shell 712, thereby realizing the boltless fixing of the universal signal connector 741, and at the same time, due to the embedded fixing structure between the recorder main control board 751 and the anti-disengagement limiting groove 795, the connector fixing plate 792 cannot be popped out from the insertion direction (limited by the foregoing embedded fixing structure);

[0209] When the universal signal connector 741 needs to be replaced, the connector fixing plate 792 is pulled away (pulled backward) from the contact area of the recorder main control board 751, the recorder main control board 751 is disengaged from the anti-disengagement limiting groove 795, the connector fixing plate 792 can be taken out, at this time, the universal signal connector 741 will be in a movable state between the recorder middle shell 712 and the connector fixing block 791, thereby conveniently taking out and replacing the universal signal connector 741.

[0210] As shown in Figure 16 The first host plug-in end 115 includes a plurality of mutually adapted connection points (the first host plug-in end 115 includes at least two connection points, and the recorder plug-in end 733 also includes at least two connection points), at least one or more of which is a power distribution connection point 1154, and at least one or more of which is a signal connection point 1155, wherein the power distribution connection point 1154 of the first host plug-in end 115 is electrically connected through the connection circuit board 110 and the output connection point 1131 of the first main control plug-in end 113, and the signal connection point 1155 of the first host plug-in end 115 is electrically connected through the connection circuit board 110 and the signal connection point 1133 of the first main control plug-in end 113;

[0211] Correspondingly, the recorder plug-in end 733 comprises at least one or more power supply connection points 7331 and at least one or more signal connection points 7332, wherein the power supply connection points 7331 and the signal connection points 7332 are respectively connected to the recorder main control board 751 through different connection channels.

[0212] When the multi-channel recorder 700 is adaptively connected to the temperature verification host, firstly, the electric energy is transmitted from the battery module 600 of the temperature verification host to the main control module 500, and then transmitted from the main control module 500 to the power supply connection points 7331 of the first host plug-in end 115, and then transmitted to the multi-channel recorder 700 through the adaptive connection between the first host plug-in end 115 and the recorder plug-in end 733, and the electric energy is managed by the recorder main control board 751 and configured to each power consumption module; or, after the electric energy is transmitted from the temperature verification host to the multi-channel recorder 700, the electric energy is transmitted to the recorder power supply module 760 by the recorder main control board 751, so as to charge the recorder power supply module 760; or, a combination of the above two cases.

[0213] In order to make the multi-channel recorder 700 adapt to the recorder installation compartment fixedly arranged in the temperature verification host, taking the first recorder installation compartment 171 and the multi-channel recorder 700 as an example, as shown in Figure 17 , the first recorder installation compartment 171 is provided with a first recorder compartment opening on the rear shell 106, the width and height of the first recorder compartment opening are substantially the same as the width and height of the multi-channel recorder 700, so that the multi-channel recorder 700 can pass through the first recorder compartment opening and be placed in the first recorder installation compartment 171, the front-rear length of the first recorder installation compartment 171 is substantially the same as the front-rear length of the multi-channel recorder 700, the height of the first recorder installation compartment 171 is substantially the same as the height of the multi-channel recorder 700, and the width of the first recorder installation compartment 171 is substantially the same as the width of the multi-channel recorder 700, so that the multi-channel recorder 700 can be exactly accommodated in the first recorder installation compartment 171; the first recorder compartment door 1711 is arranged at the first recorder compartment opening, the first recorder compartment door 1711 is a switchable door, specifically, the first recorder compartment door 1711 is hinged at the upper end to the rear shell 106, when the multi-channel recorder 700 is placed in the first recorder installation compartment 171, the first recorder compartment door 1711 is clamped between the upper end surface of the multi-channel recorder 700 and the upper shell 101 (the upper end surface of the first recorder installation compartment 171), and is in a continuously opened state, when the multi-channel recorder 700 is taken out of the first recorder installation compartment 171, and the first recorder installation compartment 171 is in an empty state, the first recorder compartment door 1711 is restored to the position of the first recorder compartment opening under the influence of gravity.

[0214] As shown in Figure 18As shown, the multi-channel recorder 700 and the recorder mounting compartment (171, 172) are provided with detachable fixing structures;

[0215] The rear housing 106 is symmetrically provided with a first locking mechanism 180 for adapting to the multi-channel recorder 700 on the left and right parts, the first locking mechanism 180 extends along the front and rear directions, and is respectively located on the left and right inner side surfaces of the first recorder mounting compartment 171;

[0216] Correspondingly, the multi-channel recorder 700 is symmetrically provided with a second locking mechanism 780 for adapting to the first locking mechanism 180 on the left and right side surfaces, when the multi-channel recorder 700 is placed in the first recorder mounting compartment 171, the first locking mechanism 180 and the second locking mechanism 780 are adapted and locked.

[0217] Taking the first locking mechanism 180 and the second locking mechanism 780 on the left side as an example for specific description.

[0218] As shown, Figure 19 The first locking mechanism 180 includes a guide strip 181, a locking block 182 and an unlocking push rod 183.

[0219] One end of the guide strip 181 is fixedly arranged on the rear housing 106, the other end extends in the forward direction (i.e. extends into the first recorder mounting compartment 171), the middle part of the guide strip 181 is provided with a locking block 182 movable blind hole 1811, the opening direction of the locking block 182 movable blind hole 1811 is right, the locking block 182 can move in the locking block 182 movable blind hole 1811, the front part of the guide strip 181 is provided with an unlocking cavity 1812, the unlocking push rod 183 can move in the unlocking cavity 1812, the unlocking cavity 1812 extends forward to communicate with the locking block 182 movable blind hole 1811, and the unlocking cavity 1812 extends rearward to the rear housing 106.

[0220] The right end of the lock block 182 (i.e. the end towards the inside of the first recorder mounting compartment 171) is provided with a first limiting slope surface 1821 and a second limiting slope surface 1822. Specifically, the right end rear side of the lock block 182 forms a first limiting slope surface 1821 extending from the left rear to the right front, the included angle between the first limiting slope surface 1821 and the front-rear direction (i.e. the movement direction of the multi-channel recorder 700 relative to the first recorder mounting compartment 171) is the slope angle of the first limiting slope surface 1821, and the right end front side of the lock block 182 forms a second limiting slope surface 1822 extending from the left front to the right rear, the included angle between the second limiting slope surface 1822 and the front-rear direction is the slope angle of the second limiting slope surface 1822; the slope angle of the first limiting slope surface 1821 is less than or equal to the slope angle of the second limiting slope surface 1822; the left end of the lock block 182 is provided with an unlocking slope surface 1823, specifically, the left end rear side of the lock block 182 is protruded rearward, and the protruded area extends from the left rear to the right front to form the unlocking slope surface 1823; the projection positions of the first limiting slope surface 1821, the second limiting slope surface 1822 and the unlocking slope surface 1823 in the front-rear direction do not coincide, the front-rear direction projection of the unlocking slope surface 1823 is closest to the rear, the front-rear direction projection of the second limiting slope surface 1822 is closest to the front, and the front-rear direction projection of the first limiting slope surface 1821 is between the two.

[0221] The hole diameter of the lock block 182 movable blind hole 1811 and the outer diameter of the lock block 182 are matched, specifically, the front-rear direction length of the lock block 182 movable blind hole 1811 and the front-rear direction length of the right part and the middle part of the lock block 182 are basically the same, and the up-down direction length of the lock block 182 movable blind hole 1811 and the up-down direction length of the right part and the middle part of the lock block 182 are basically the same, so that the lock block 182 movable blind hole 1811 can just accommodate the lock block 182, while limiting the movement of the lock block 182 in the front-rear direction and the up-down direction; the depth (i.e. the left-right direction length) of the lock block 182 movable blind hole 1811 is greater than the left-right direction length of the lock block 182, so that the lock block 182 can move in the left-right direction in the lock block 182 movable blind hole 1811; the left end surface of the lock block 182 and the bottom surface of the lock block 182 movable blind hole 1811 are provided with a lock block elastic member 1824, the elastic force direction of the lock block elastic member 1824 is to the right, and under the influence of the elastic force of the lock block elastic member 1824, the right part of the lock block 182 is exposed outside the lock block 182 movable blind hole 1811 (into the first recorder mounting compartment 171); the unlocking slope surface 1823 of the lock block 182 is inserted into the unlocking cavity 1812, and the left-right direction length of the communication part between the lock block 182 movable blind hole 1811 and the unlocking cavity 1812 is greater than the left-right direction length of the unlocking slope surface 1823, so that the unlocking slope surface 1823 can move in the left-right direction in the unlocking cavity 1812.

[0222] The periphery profile of the unlocking push rod 183 and the periphery profile of the unlocking cavity 1812 match, specifically, the length in left-right direction of the unlocking push rod 183 and the length in left-right direction of the unlocking cavity 1812 are basically the same, the height (length in up-down direction) of the unlocking push rod 183 and the height of the unlocking cavity 1812 are basically the same, thereby limiting the unlocking push rod 183 to move in front-back direction within the unlocking cavity 1812, and the unlocking elastic member 1831 is further arranged between the unlocking push rod 183 and the guide strip 181, the elastic force direction of the unlocking elastic member 1831 is backward, thereby exposing the rear end of the unlocking push rod 183 from the rear shell 106; the front end of the unlocking push rod 183 is provided with the unlocking reverse slope surface 1832 matched with the unlocking slope surface 1823, the direction of the unlocking reverse slope surface 1832 is exactly opposite to the unlocking slope surface 1823, and the unlocking reverse slope surface 1832 at least partially contacts with the unlocking slope surface 1823.

[0223] Corresponding to the first locking mechanism 180 located on the left side, the second locking mechanism 780 on the multi-channel recorder 700 comprises the first lock slot 781 and the second lock slot 782 arranged on the left side of the multi-channel recorder 700, the first lock slot 781 is relatively rear, and the second lock slot 782 is relatively front.

[0224] The distance between the first lock slot 781 and the front end surface plane of the multi-channel recorder 700 is basically equal to the distance between the lock block 182 and the front end surface of the first recorder mounting bin 171, and the distance between the second lock slot 782 and the front end surface plane of the multi-channel recorder 700 is less than the distance between the lock block 182 and the front end surface of the first recorder mounting bin 171;

[0225] The first lock slot 781 comprises the rear first limiting slot surface 7811 and the front second limiting slot surface 7812, the slot structure of the first lock slot 781 matches with the right end of the lock block 182, when the lock block 182 is located in the first lock slot 781 and is in the non-unlocking state, the first limiting slot surface 7811 and the first limiting slope surface 1821 are exactly opposite and match closely, and the second limiting slot surface 7812 and the second limiting slope surface 1822 are exactly opposite and match closely;

[0226] The depth (length in left-right direction) of the second lock slot 782 is less than the depth of the first lock slot 781, the second lock slot 782 comprises the rear third limiting slot surface 7821 and the front fourth limiting slot surface 7822, the third limiting slot surface 7821 corresponds to the first limiting slope surface 1821, and the included angle between the third limiting slot surface 7821 and the front-back direction is less than or equal to the slope angle of the first limiting slope surface 1821, the fourth limiting slot surface 7822 corresponds to the second limiting slope surface 1822, and the included angle between the fourth limiting slot surface 7822 and the front-back direction is less than or equal to the slope angle of the second limiting slope surface 1822, when the lock block 182 is located in the second lock slot 782, only part of the first limiting slope surface 1821 contacts with the third limiting slot surface 7821, and only part of the second limiting slope surface 1822 contacts with the fourth limiting slot surface 7822.

[0227] The first locking mechanism 180 on the right side of the first recorder mounting compartment 171 and the first locking mechanism 180 on the left side are axis-symmetrical with the middle line of the first recorder mounting compartment 171 as the axis, and the second locking mechanism 780 on the right side of the multi-channel recorder 700 and the second locking mechanism 780 on the left side are also axis-symmetrical, so the first locking mechanism 180 on the right side of the first recorder mounting compartment 171 and the second locking mechanism 780 on the right side of the multi-channel recorder 700 will not be described again.

[0228] As shown in the following figure, the first locking mechanism 180 and the second locking mechanism 780 are shown in the locked state and the unlocked state: Figure 20

[0229] In the locked state, such as the first locking mechanism 180 and the second locking mechanism 780 on the left side, at this time, the unlocking push rod 183 is in a slightly backward position, the lock block 182 is protruded from the lock block movable blind hole 1811 under the influence of the elastic force of the lock block elastic member 1824, and is adapted to be inserted into the first locking groove 781 on the left side of the multi-channel recorder 700, at this time, the first limiting slope surface 1821 and the first limiting groove surface 7811 are clamped, and the second limiting slope surface 1822 and the second limiting groove surface 7812 are clamped, so that the multi-channel recorder 700 cannot move in the front-back direction;

[0230] In the unlocked state, such as the first locking mechanism 180 and the second locking mechanism 780 on the right side, at this time, after pressing the rear end of the unlocking push rod 183, the unlocking push rod 183 moves to a slightly forward position, the unlocking slope surface 1823 on the lock block 182 is subjected to the thrust force from the unlocking reverse slope surface 1832 of the end of the unlocking push rod 183, because the guide strip 181 restricts the lock block 182 from moving in the front-back direction, and the slope angle of the unlocking slope surface 1823 and the unlocking reverse slope surface 1832 makes the force be decomposed into front-back direction force and left-right direction force, therefore, the lock block 182 overcomes the elastic force of the lock block elastic member 1824 and retreats into the lock block movable blind hole 1811, at this time, the first locking groove 781 on the right side of the multi-channel recorder 700 is not limited by the lock block 182, allowing the multi-channel recorder 700 to move in the front-back direction.

[0231] In cooperation with the first locking mechanism 180 and the second locking mechanism 780, the front end surface of the first recorder mounting compartment 171 (i.e. the middle partition plate 105) is also provided with the first host plug end 115 and the recorder ejection mechanism 173.

[0232] As shown in the following figure, the first locking mechanism 180 and the second locking mechanism 780 are shown in the locked state and the unlocked state: Figure 21 ​As shown, the first host docking end 115 includes a docking end head 116, a docking end limiting frame 117 and a docking end positioning member 117. The docking end head 116 is movable in the up, down, left and back directions within the docking end limiting frame 117. The docking end positioning member 117 is a magnetic member and is fixed on the docking end head 116. Correspondingly, the recorder docking end 733 is aligned with the larger range of the docking end limiting frame 117. When the multi-channel recorder 700 is placed in the first recorder mounting cavity 171, the recorder docking end 733 is docked with the first host docking end 115. The docking end positioning member 117 is affected by the positioning magnetic force on the recorder docking end 733 and is pulled to the position aligned with the recorder docking end 733. In addition, in order to facilitate the positioning effect of the docking end positioning member 117, a magnetic member adapted thereto can be arranged on the recorder docking end 733.

[0233] The recorder ejection mechanism 173 includes an elastic member with a rearward elastic direction. When the multi-channel recorder 700 is completely placed in the first recorder mounting cavity 171, the lock block 182 and the first lock groove 781 are adapted and locked, the recorder ejection mechanism 173 is in contact with the front end surface of the multi-channel recorder 700, so as to apply the rearward elastic force to the multi-channel recorder 700.

[0234] Further, the length of the recorder ejection mechanism 173 in the front-rear direction is less than or equal to the difference between the positions of the first lock groove 781 and the second lock groove 782 in the front-rear direction. When the lock block 182 is located in the second lock groove 782, the recorder ejection mechanism 173 is not in contact with the multi-channel recorder 700.

[0235] The second recorder mounting cavity 172 is provided with the same first locking mechanism 180 and recorder ejection mechanism 173 as the first recorder mounting cavity 171. The second host docking end 116 has the same structure as the first host docking end 115. Therefore, the first locking mechanism 180, the second host docking end 116 and the recorder ejection mechanism 173 in the second recorder mounting cavity 172 will not be described again.

[0236] Taking the adaptive mounting relationship between the first recorder mounting cavity 171 and the multi-channel recorder 700 as an example, the working process is described.

[0237] When the first recorder mounting cavity 171 is empty, the unlocking elastic member 1831 drives the unlocking push rod 183 to move backward as far as possible, and the unlocking reverse slope surface 1832 moves to the right rear direction in linkage with the unlocking push rod 183. The locking block elastic member 1824 drives the locking block 182 to move to the right in the locking block 182 movable blind hole 1811. The unlocking slope surface 1823 moves to the right in linkage with the locking block 182. When the unlocking slope surface 1823 and the unlocking reverse slope surface 1832 are in contact, the locking block 182 at least partially exposes from the locking block 182 movable blind hole 1811;

[0238] When the multi-channel recorder 700 is placed into the first recorder mounting cavity 171, the left and right sidewalls of the multi-channel recorder 700 are in contact with the locking block 182. At this time, the first limiting slope surface 1821 has a certain slope angle, and the angle is relatively small (not greater than the slope angle of the second limiting slope surface 1822), so the multi-channel recorder 700 can be easily pushed further. At this time, the locking block 182 is subjected to a force in the forward direction. Since the force receiving surface (the first limiting slope surface 1821) has a certain angle relative to the forward and backward directions and the left and right directions, and the locking block 182 is limited by the locking block 182 movable blind hole 1811 and cannot move in the forward and backward directions, the locking block 182 is subjected to force conversion and moves into the locking block 182 movable blind hole 1811 until the exposed part of the locking block 182 does not affect the movement of the multi-channel recorder 700 / the locking block 182 is not exposed in the locking block 182 movable blind hole 1811;

[0239] Continue to place the multi-channel recorder 700 into the first recorder mounting cavity 171, and the locking block 182 first enters the second locking groove 782. Since the second locking groove 782 is relatively shallow, the resistance when the first limiting slope surface 1821 of the locking block 182 is contacted can be easily overcome, so that the multi-channel recorder 700 continues to move until the exposed part of the locking block 182 does not affect the movement of the multi-channel recorder 700 / the locking block 182 is not exposed in the locking block 182 movable blind hole 1811;

[0240] Continue to place the multi-channel recorder 700 into the first recorder mounting cavity 171, and the locking block 182 enters the first locking groove 781. Since the front end surface of the multi-channel recorder 700 has contacted the front end surface of the first recorder mounting cavity 171, the multi-channel recorder 700 does not involve further movement in the forward direction. Since the first locking groove 781 is deep and matched with the shape of the locking block 182, the locking block 182 is locked between the first locking groove 781 under the influence of the locking block elastic member 1824, and the multi-channel recorder 700 is detachably fixed in the first recorder mounting cavity 171;

[0241] When the multi-channel recorder 700 needs to be removed, push the unlocking push rod 183 forward. The unlocking reverse slope 1832 on the front end of the unlocking push rod 183 moves forward. Due to the angle and position limitations, the unlocking slope 1823, which is in contact with the unlocking reverse slope 1832, moves in the opposite direction against the elastic force of the locking block elastic element 1824 until the locking block 182 disengages from the first locking groove 781. At this time, under the influence of the elastic force of the recorder ejection mechanism 173, the multi-channel recorder 700 is ejected a distance until the locking block 182 enters the second locking groove 782. At least part of the multi-channel recorder 700 is exposed outside the first recorder mounting compartment 171. If you want to continue to remove the multi-channel recorder 700, you can continue to pull it outward through the exposed part of the multi-channel recorder 700.

[0242] Through the adapter connection of the first host connector 115 and the recorder connector 733, the temperature verification host and the multi-channel recorder 700 conduct electrical interaction (including data signal interaction of temperature verification tasks, temperature verification information, etc.) and transmit power.

[0251] The tester and the data collector of the embodiment, by setting the accommodation slot accommodating the inserted data collector in the tester, construct the data collector capable of being inserted into the accommodation slot from the outside, and by setting the limiting mechanism in the accommodation slot, realize that the data collector is sequentially clamped in the first position and the second position when the data collector is inserted into the accommodation slot along the first direction, and by setting the telescopic elastic protruding end in the accommodation slot, make the elastic protruding end provide the data collector with the elastic force in the second direction opposite to the first direction when the data collector is clamped in the second position, and when the limiting mechanism releases the data collector from the second position, the elastic protruding end pops the data collector from the second position to the first position. Thus, the data collector is clamped in the tester, and the data collector is easily popped out. The risk of the data collector and the tester being separated caused by moving the tester or touching the data collector can be reduced.
