Description

Technical Field

[0001] This utility model belongs to the technical field of temperature measuring devices, specifically relating to a quick-release temperature sensor replacement device. Background Technology

[0002] The self-powered wireless temperature measurement device is an intelligent device used to monitor ambient or equipment temperature in real time. Its core function is to collect, transmit and manage temperature data through wireless technology, ensuring the safe and stable operation of the monitored target.

[0003] The self-powered wireless temperature measurement device mainly includes a temperature sensing module, a wireless transmission module, and a data management and early warning module. The temperature sensor in the temperature sensing module is a component. After the temperature sensor is installed on the temperature measurement device, it is connected to other modules via wires. During installation, this structure is usually fixed with threaded connectors. That is, the threaded connectors need to be tightened when installing and removing the temperature sensor to ensure stable installation. Different people tighten the threaded connectors to different degrees, which makes the connection unstable. Moreover, the tightening process of the threaded connectors is time-consuming and requires a lot of effort. Since the temperature probe in the temperature sensor needs to contact the switch contact, it is a vulnerable part. The above connection method is not conducive to the frequent replacement of the temperature probe. Utility Model Content

[0004] This utility model provides a quick-release temperature sensor replacement device, which aims to solve the technical problems of the unstable installation of temperature sensors in existing self-powered wireless temperature measurement devices using threaded connectors, the laborious operation process, and the inconvenience of frequent temperature probe replacement.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a quick-release temperature sensor replacement device, comprising: The housing has a sidewall for mounting a temperature sensor. The sidewall has an insertion hole and strip holes spaced around the outer periphery of the insertion hole. The strip holes extend along an arc path, the axis of which coincides with the center of the insertion hole. The sidewall of the strip holes is provided with mating holes. Temperature sensor body; The quick-release module includes a rod fixed to the body of the temperature sensor and a connector on the outer periphery of the rod. The connector has a retractable insertion part. The rod is inserted into the socket and the connector is used to slide within the slot. When the insertion rod is inserted into the insertion hole, the connector simultaneously extends into the strip hole. The insertion rod is rotated until the insertion part corresponds to the position of the mating hole. The insertion part extends out and engages with the mating hole to fix the body of the temperature sensor.

[0006] In one possible implementation, the connector includes: A first fixing block is fixed to the outer periphery of the insertion rod, and a groove is provided on the first fixing block; A first spring is placed in the groove, and one end of the first spring is fixedly connected to the bottom wall of the groove. An abutment ball is fixed to the end of the first spring. The abutment ball is used to extend out of the groove and into the mating hole under the extrusion force of the first spring. The abutting ball forms the insertion part.

[0007] In one possible implementation, the abutting ball includes a housing and a ball hinged to the housing, with the end of the first spring fixedly connected to the housing.

[0008] In one possible implementation, the connector includes: The second fixing block has a strip groove; Two second springs are disposed within the strip groove and distributed relative to each other; The spring sheet has two ends connected to the two second springs respectively; The two second springs are used to press the spring at both ends of the spring, so that the middle part of the spring protrudes and extends into the mating hole.

[0009] In one possible implementation, guide posts are provided at both ends of the strip groove, each guide post having a cylindrical cavity, and the second spring is located within the cylindrical cavity; Both ends of the spring are provided with fixing rods, which slide in conjunction with the cylindrical cavity and are fixedly connected to the second spring.

[0010] In one possible implementation, the quick-release module further includes a limiting rod connected between the insert and the connector, wherein the limiting rod abuts against the side wall when the insert extends into the insertion hole and the connector extends into the strip hole.

[0011] In one possible implementation, the limiting rod has an oil reservoir on the side facing the sidewall.

[0012] In one possible implementation, multiple strip-shaped holes are evenly distributed around the axis of the insertion hole.

[0013] In one possible implementation, the end of the socket is chamfered.

[0014] In one possible implementation, the insert has a tip corresponding to the chamfer.

[0015] Compared with the prior art, the solution shown in this application embodiment has a quick-release module on the temperature sensor body. When installing the temperature sensor body, the plug on the quick-release module is inserted into the socket of the outer shell. The connector extends into the strip hole on the outer periphery of the socket along with the plug. At this time, the plug can be twisted. When the plug rotates, it drives the connector to move along the extension path of the strip hole. During this process, the plug part is in a retracted state. When the plug rotates to the state where the plug part corresponds to the mating hole, the plug part extends out and mates with the mating hole. The plug can no longer rotate and cannot be pulled out, thus completing the fixation of the temperature sensor body. The installed temperature sensor body is fixed on the side wall of the outer shell. The temperature probe in the temperature sensor body protrudes from the inner circumferential surface of the outer shell. When the outer shell is fitted onto the switch contact, the temperature probe abuts against the switch contact to measure its temperature. In this embodiment, the temperature sensor body can be installed through the process of insertion, rotation, and locking. Disassembly is performed by reversing the operation. The entire process is simple, shortens the installation and disassembly time, and improves work efficiency. Furthermore, no external tools are needed during the operation, which reduces the difficulty of operation and avoids wear and tear on the temperature probe caused by improper use of tools.

[0024] Please refer to the following: Figures 1 to 4 The quick-release temperature sensor replacement device provided by this utility model will now be described. The quick-release temperature sensor replacement device includes a housing 10, a temperature sensor body 20, and a quick-release module 30. The housing 10 has a side wall 11 for installing the temperature sensor. The side wall 11 has an insertion hole 12 and a strip hole 13 spaced around the outer periphery of the insertion hole 12. The strip hole 13 extends along an arc path, and the axis of the arc path coincides with the center of the insertion hole 12. The side wall 11 of the strip hole 13 is provided with a mating hole 14. The quick-release module 30 includes an insertion rod 31 fixed to the temperature sensor body 20 and a connector 32 provided around the outer periphery of the insertion rod 31. The connector 32 is provided with a retractable insertion part. The insertion rod 31 is inserted into the insertion hole 12, and the connector 32 is used to slide within the strip hole 13. When the insertion rod 31 is inserted into the insertion hole 12, the connector 32 simultaneously extends into the strip hole 13. The insertion rod 31 is rotated until the insertion part corresponds to the position of the mating hole 14. The insertion part extends out and mates with the mating hole 14 to fix the temperature sensor body 20.

[0025] In the prior art, the aforementioned housing 10 is the housing 10 of the temperature measuring device. The temperature sensor body 20 is installed on the housing 10. The housing 10 of the temperature measuring device usually adopts a ring structure. The temperature sensor body 20 is installed on the inner circumference of the ring structure. By fitting the ring structure housing 10 onto the switch contact, the temperature probe in the temperature sensor body 20 can abut against the switch contact. Thus, when the switch contact is working, the temperature change of the switch contact can be monitored in real time. The monitored values ​​are transmitted to external equipment via a wireless transmission module for easy viewing by personnel. When the temperature of the switch contact exceeds the standard, an alarm can also be issued on the equipment to remind the operator.

[0026] It should be noted that the side wall 11 on the outer shell 10 in this application is the same as the side wall 11 used for installing the temperature sensor body 20 in the prior art. Based on the fact that the outer shell 10 is a ring structure, if the temperature sensor body 20 is directly installed in the inner ring of the outer shell 10, then the side wall 11 refers to the inner ring side wall 11 of the outer shell 10; when the temperature sensor is installed in the receiving groove opened in the inner ring of the outer shell 10, then the side wall 11 refers to the bottom wall of the receiving groove; since the inner circumferential surface of the outer shell 10 is a ring surface, in order to facilitate the insertion rod 31 to drive the connector 32 to rotate, the side wall 11 used for installing the temperature sensor can be set as a plane.

[0027] Compared with the prior art, the quick-release temperature sensor replacement device provided in this embodiment has a quick-release module 30 on the temperature sensor body 20. When installing the temperature sensor body 20, the insertion rod 31 on the quick-release module 30 is inserted into the insertion hole 12 of the outer shell 10. The connector 32 extends into the slotted hole 13 on the outer periphery of the insertion hole 12 along with the insertion rod 31. At this time, the insertion rod 31 can be twisted. When the insertion rod 31 rotates, it drives the connector 32 to move along the extension path of the slotted hole 13. During this process, the insertion part is in a retracted state. When the insertion rod 31 is rotated to the position where the insertion part corresponds to the mating hole 14, the insertion part extends and engages with the mating hole 14, and the insertion hole 12 can no longer be rotated or pulled out, thus completing the fixation of the temperature sensor body 20. The installed temperature sensor body 20 is fixed on the side wall 11 of the outer shell 10. The temperature probe in the temperature sensor body 20 protrudes from the inner circumferential surface of the outer shell 10. When the outer shell 10 is fitted onto the switch contact, the temperature probe abuts against the switch contact to measure its temperature. In this embodiment, the installation of the temperature sensor body 20 can be achieved through the process of insertion, rotation, and engagement. Disassembly is performed by reversing the operation. The entire operation process is simple, shortening the installation and disassembly time and improving work efficiency. Furthermore, no external tools are needed during the operation, reducing the difficulty of operation and avoiding wear of the temperature probe due to improper tool use.

[0028] In some embodiments, a specific implementation of the connector 32 described above may employ, as follows: Figure 3 The structure shown. See also Figure 3 The connector 32 includes a first fixing block 33, a first spring 34, and an abutment ball 35. The first fixing block 33 is fixed to the outer periphery of the insertion rod 31 and has a groove. The first spring 34 is placed in the groove and one end of the first spring 34 is fixed to the bottom wall of the groove. The abutment ball 35 is fixed to the end of the first spring 34 and is used to extend out of the groove and into the mating hole 14 under the extrusion force of the first spring 34. The abutment ball 35 forms an insertion part.

[0029] When the insertion rod 31 is inserted into the insertion hole 12, the connector 32 is inserted into the strip hole 13. Under the pressure of the side wall 11 of the strip hole 13, the abutment ball 35 compresses the first spring 34. The insertion rod 31 is rotated, and the insertion rod 31 drives the connector 32 to move in the strip hole 13. When the position of the abutment ball 35 corresponds to that of the mating hole 14, the first spring 34 resumes to drive the abutment ball 35 to extend and enter the mating hole 14. The mating of the abutment ball 35 and the mating hole 14 can ensure that the insertion rod 31 cannot continue to rotate and be pulled out when the temperature sensor body 20 is in normal use. However, the insertion rod 31 can be pulled out under strong force.

[0030] In this embodiment, the first spring 34 can drive the abutment ball 35 to extend and retract through elastic force, stably realizing the extension and retraction of the insertion part, ensuring that the abutment ball 35 can be inserted into the mating hole 14 during installation and can be smoothly disengaged from the mating hole 14 during disassembly, thus ensuring the reliable realization of the quick-release function; the elastic effect of the first spring 34 makes the engagement between the abutment ball 35 and the mating hole 14 have a certain buffering effect, reducing damage to the side wall 11, while also ensuring that the abutment ball 35 and the mating hole 14 always maintain a good contact state, further improving the connection stability.

[0031] Optionally, the shape and size of the groove can be designed according to the specifications of the first spring 34 and the abutment ball 35. It is usually a cylindrical groove with a flat bottom surface to ensure the stability of the first spring 34 after installation. The free length of the first spring 34 is greater than the depth of the groove to ensure that the abutment ball 35 can be pushed out of the groove in a natural state. The diameter of the abutment ball 35 is slightly smaller than the opening of the groove to ensure that it can extend out of the groove without falling off.

[0032] Specifically, see Figure 3 The abutting ball 35 includes a housing 351 and a ball 352 that is ball-jointed with the housing 351, and the end of the first spring 34 is fixedly connected to the housing 351. The housing 351 has an opening in its side wall 11 facing the slotted hole 13, which has a mating hole 14. The ball 352 is located inside the housing 351 but will not come out of the housing 351 (this is achieved by the opening size on the housing 351 being smaller than the diameter of the ball 352). When the connector 32 is located inside the slotted hole 13, the ball 352 abuts against the side wall 11 of the slotted hole 13. When the connector 32 moves along the extension path of the slotted hole 13, there is rolling friction between the ball 352 and the side wall 11 of the slotted hole 13, which makes the friction less during the rotation of the insertion rod 31, the operation smoother, and facilitates the insertion part to quickly align with the mating hole 14. At the same time, the rolling friction between the ball 352 and the side wall 11 of the slotted hole 13 can reduce the wear of the abutting ball 35 and the side wall 11 of the slotted hole 13, and extend the service life of the device.

[0033] In some embodiments, a modified implementation of the connector 32 described above can be as follows: Figure 4 The structure shown. See also Figure 4 The connector 32 includes a second fixing block 36, two second springs 37, and a spring piece 38. The second fixing block 36 has a strip groove 361. The two second springs 37 are disposed in the strip groove 361 and are distributed relative to each other. The two ends of the spring piece 38 are respectively connected to the two second springs 37. The two second springs 37 are used to press the spring piece 38 at both ends so that the middle part of the spring piece 38 protrudes and extends into the mating hole 14.

[0034] It is easy to understand that the strip groove 361 is a straight groove, and in its length direction, the two second springs 37 are located at the two ends of the strip groove 361, and the spring piece 38 is located between the two second springs 37.

[0035] When the connector 32 enters the slot 13, the side wall 11 of the slot 13 abuts against the middle of the spring piece 38. The elastic deformation of the spring piece 38 abuts against the two second springs 37 at both ends. The second springs 37 are compressed. During the movement of the connector 32 in the slot 13, when the middle of the spring piece 38 corresponds to the mating hole 14, the two second springs 37 are reset, squeezing the middle of the spring piece 38 to bulge outward and thus extend into the mating hole 14 to complete the fixation of the temperature sensor body 20.

[0036] In this embodiment, the spring sheet 38 is made of a thin metal sheet with good elasticity and plasticity. The second springs 37 at both ends compress the spring at both ends of the spring sheet 38, which can ensure a reliable locking force when the spring sheet 38 is engaged with the mating hole 14 in the middle, effectively preventing the connector 32 from loosening during use and ensuring the stable installation of the temperature sensor body 20. The spring sheet 38 has a certain elastic deformation capability, which can adapt to the gap deviation between the mating hole 14 and the spring sheet 38 within a certain range. Even if there is a small dimensional error in the mating hole 14, the spring sheet 38 can achieve a good fit through its own deformation, which improves the versatility and fault tolerance of the device.

[0037] To facilitate the movement of the connector 32 within the slot 13, the inner wall of the slot 13 can be smoothed to reduce the frictional resistance between the spring 38 and the inner wall of the slot 13.

[0038] Specifically, see Figure 4 The strip groove 361 has guide posts 362 at both ends, each guide post 362 having a cylindrical cavity, within which the second spring 37 is located. The spring piece 38 has fixing rods 381 at both ends, which slide within the cylindrical cavity and are fixedly connected to the second spring 37. The fixing rods 381 do not undergo elastic deformation during movement. When the ends of the spring piece 38 abut against the second spring 37, the abutment is actually achieved through the fixing rods 381. This process ensures that the extension and retraction of the second spring 37 remain within the cylindrical cavity, providing guidance for the extension and retraction of the second spring 37, limiting the radial deformation of the second spring 37, and preventing the spring piece 38 from shifting or tilting during movement, thus ensuring the stability and reliability of the spring piece 38's movement.

[0039] In some embodiments, a specific implementation of the quick-release module 30 described above can be as follows: Figure 1 , Figure 3 and Figure 4 The structure shown. See also Figure 1 , Figure 3 and Figure 4The quick-release module 30 also includes a limiting rod 39 connecting the insertion rod 31 and the connector 32. When the insertion rod 31 extends into the insertion hole 12 and the connector 32 extends into the slotted hole 13, the limiting rod 39 abuts against the side wall 11. When the insertion rod 31 is inserted into the insertion hole 12, the limiting rod 39 abuts against the side wall 11, preventing the insertion rod 31 from being inserted further. At the same time, the connector 32 is already located in the slotted hole 13. The limiting rod 39 not only connects the insertion rod 31 and the slotted hole 13 but also limits the installation, simplifying the installation process of the insertion rod 31. During use, the limiting rod 39 abutting against the side wall 11 also improves the stability of the temperature sensor body 20, preventing inaccurate temperature readings caused by shaking during use.

[0040] Specifically, see Figure 3 An oil reservoir 391 is provided on the side of the limiting rod 39 facing the side wall 11. When the insertion rod 31 rotates, since the limiting rod 39 abuts against the side wall 11, the oil reservoir 391 can conveniently store lubricating oil. Thus, during the friction between the limiting rod 39 and the side wall 11, the lubricating oil plays a lubricating role, reducing the frictional resistance during the rotation of the insertion rod 31, and reducing the noise generated by the friction between the limiting rod 39 and the side wall 11. The oil reservoir 391 can continuously provide lubricating oil to the friction plate, preventing the lubricating oil from being lost too quickly and ensuring long-term lubrication effect.

[0041] In some embodiments, a specific implementation of the above-described strip hole 13 can be as follows: Figures 1 to 3 The structure shown. See also Figures 1 to 3 Multiple strip holes 13 are evenly distributed around the axis of the insertion hole 12. Two to four strip holes 13 can be set as needed. The dimensions of the multiple strip holes 13 are exactly the same, and the included angle between two adjacent strip holes 13 is equal. When installing the insertion rod 31, the connector 32 can be aligned with any one of the strip holes 13, simplifying the installation process.

[0042] Specifically, multiple connectors 32 can be provided on the outer periphery of the insertion rod 31, with each connector 32 corresponding to a strip hole 13. This structure can form multi-point fixation, improve the installation stability of the temperature sensor body 20, and ensure balanced force.

[0043] In some embodiments, an improved implementation of the above-described socket 12 may employ, as follows: Figure 1 The structure shown. See also Figure 1The end of the socket 12 is provided with a chamfer 121. Since the outer shell 10 is annular, the end of the socket 12 facing the axial direction of the outer shell 10 is provided with a chamfer 121. The chamfer 121 makes the end of the socket 12 facing the axial direction of the outer shell 10 form an enlarged conical opening. Even if there is a slight coaxiality deviation between the plug rod 31 and the socket 12, the end of the plug rod 31 can smoothly enter the socket 12 under the guidance of the chamfer 121, avoiding the situation where the plug rod 31 gets stuck at the entrance of the socket 12.

[0044] Correspondingly, see Figure 2 The insertion rod 31 has a tip 311 corresponding to the chamfer 121. The tip 311 is conical or frustum-shaped, and its taper matches the angle of the chamfer 121. Under the dual guiding effect of the chamfer 121 and the tip 311, the insertion rod 31 can enter the socket 12 more accurately and smoothly.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
