Description

Technical Field

[0001] The utility model relates to the technical field of temperature calibrators, in particular to a cavity-type blackbody temperature calibrator. Background Art

[0002] Temperature calibrators can determine and correct the errors of temperature instruments to improve the accuracy of temperature measurement. Temperature calibrators are widely used in the fields of petroleum, chemical industry, electric power, metallurgy, etc. By simulating standard signals at different temperatures and comparing them with the measured values ​​of the temperature instrument being measured, the error value of the temperature instrument being measured can be obtained and corresponding calibration can be performed.

[0003] The cavity blackbody temperature calibrator is a type of temperature calibrator. It is used to calibrate thermal imagers and thermal imaging cameras. The cavity blackbody temperature calibrator has higher accuracy and higher reliability.

[0004] For example, a temperature calibrator for a dispensing machine with application number CN201220717528.7 includes a main control unit and a temperature sensor, a heater, a fan and a cooler connected thereto; the switch of the heater adopts a relay, and the relay is connected to the main control unit; the switch of the fan adopts a relay, and the relay is connected to the main control unit; the switch of the cooler adopts a relay, and the relay is connected to the main control unit. The temperature calibrator for a dispensing machine of the utility model is easy to operate and has obvious effects;

The user can rotate four sets of fixing bolts so that the four sets of fixing bolts can be separated from the inside of the corresponding threaded grooves respectively. After that, the user can use the handle to move the automatic temperature calibrator body to the corresponding side in the placement slot. At the same time, the two sets of slide rods will slide correspondingly in the inside of the corresponding slide grooves respectively, and the corresponding groups of support balls will slide correspondingly against the bottom inner wall of the placement slot, so that the automatic temperature calibrator body can stably slide to one side, so that the heat-conducting rod can move out from the temperature measuring head and the inside of the heat-conducting slot;

[0006] When working, the cavity blackbody temperature calibrator needs to be connected to the power supply through a wire. During the calibration process, various workers will pass by. However, the temperature calibrator in the above application does not have a wire protection structure during use. It is possible that a worker accidentally touches the wire, causing the plug to fall off, which brings unnecessary trouble to the worker's operation.

[0007] In view of the above problems, it is urgent to carry out innovative design based on the original cavity-type blackbody temperature calibrator. Utility Model Content

[0008] The purpose of the utility model is to provide a cavity-type blackbody temperature calibrator to solve the problem that the structure proposed in the above-mentioned background technology does not have wire protection, and a worker may accidentally touch the wire, causing the plug to fall, which brings unnecessary trouble to the worker's operation.

[0009] To achieve the above object, the utility model provides the following technical solution: a cavity-type blackbody temperature calibrator, comprising a housing, a display screen is embedded and connected to the back of the housing, and an operation key is fixedly connected to the surface of the housing, and the operation key is connected to the display screen by electrical signals;

[0010] A cavity type blackbody temperature calibrator, further comprising:

[0011] A connecting plate, the connecting plate is fixedly connected to the back of the housing, and a stabilizing plate is slidably provided on the surface of the connecting plate;

[0012] A pressure bearing block is slidably arranged inside the connecting plate, and the surface of the pressure bearing block is in contact with the stable inner wall of the connecting plate, and a plug hole is provided on the surface of the connecting plate.

[0013] Preferably, the pressure blocks are symmetrically distributed about the center of the stabilizing plate, the upper surface of the pressure blocks is in contact with the lower surface of the stabilizing plate, and the front side of the pressure blocks is inclined.

[0014] Preferably, an auxiliary plate is fixedly connected to the surface of the connecting plate, and a stabilizing spring having an elastic reset function is fixedly connected to the lower surface of the auxiliary plate, and the other side of the stabilizing spring is fixedly connected to the surface of the stabilizing plate.

[0015] Preferably, the stabilizing spring is initially in a compressed state.

[0016] Preferably, a limiting rod is fixedly connected to the surface of the connecting plate, and the limiting rod runs through the interior of the stabilizing plate, and the limiting rod is an inverted "L" structure.

[0017] Preferably, a return spring having an elastic return function is fixedly connected to the surface of the pressure block, and the other side of the return spring is fixedly connected to the inner wall of the connecting plate.

[0018] Preferably, the stabilizing plates are symmetrically distributed about the center of the insertion hole, and a baffle is fixedly connected to the end of the limiting rod.

[0019] Compared with the prior art, the utility model has the following beneficial effects: the cavity-type blackbody temperature calibrator adopts a new structural design, and its specific contents are as follows:

[0020] (1) In the initial stage of the cavity-type blackbody temperature calibrator, the top of the pressure block is supported on the lower surface of the stabilizing plate. At this time, the stabilizing plate is in a supported state. At this time, the jack is not blocked, and the normal operation of the staff to insert the plug will not be affected. The staff can install the plug into the jack normally;

[0021] Furthermore, when installing the external plug, the external plug will push the pressure block to move inside the connecting plate, and then the stabilizing plate will lose the supporting force of the pressure block, and then the stabilizing plate will drop under the action of the stabilizing spring, and finally the stabilizing plate will clamp the plug, so that the plug can remain stable;

[0022] Furthermore, the stabilizing spring makes the stabilizing plate have a tendency to move toward the socket all the time, thereby optimizing the stability of the clamping, and the stabilizing plate is distributed on the upper and lower sides of the socket, so that the external plug is installed with higher stability;

[0023] (2) In the cavity-type blackbody temperature calibrator, when the external plug is installed and the pressure block moves toward the inside of the connecting plate, the reset spring will be squeezed. When the external plug needs to be removed, the stabilizing plate is pushed away from the plug hole so that the stabilizing plate no longer squeezes the plug. After the plug is removed, the pressure block returns to its original position under the action of the reset spring, that is, the pressure block returns to the lower side of the stabilizing plate again and supports the stabilizing plate, which is convenient for the next use of the stabilizing plate.

[0024] Furthermore, during the movement of the stabilizing plate, the limit rod enables the stabilizing plate to move only in the vertical direction, and the baffle at the end of the limit rod limits the moving distance of the stabilizing plate, so that the stabilizing plate will not fall during the movement, thereby ensuring stability.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 1-Figure 6 The utility model provides the following technical solutions: a cavity-type blackbody temperature calibrator:

[0034] Embodiment 1: By setting the stabilizing plate 7, the external plug can be quickly clamped and fixed, such as Figure 1-Figure 3 As shown:

[0035] The invention comprises a housing 1, a display screen 2 is embedded and connected to the back of the housing 1, and an operation key 3 is fixedly connected to the surface of the housing 1, and the operation key 3 is connected to the display screen 2 via an electrical signal;

[0036] A cavity type blackbody temperature calibrator, further comprising:

[0037] A connecting plate 4, the connecting plate 4 is fixedly connected to the back of the shell 1, and a stabilizing plate 7 is slidably arranged on the surface of the connecting plate 4, a pressure block 6, the pressure block 6 is slidably arranged inside the connecting plate 4, and the surface of the pressure block 6 is in contact with the inner wall of the connecting plate 4, and a plug hole 5 is provided on the surface of the connecting plate 4, the pressure block 6 is symmetrically distributed about the center of the stabilizing plate 7, and the upper surface of the pressure block 6 is in contact with the lower surface of the stabilizing plate 7, and the front side of the pressure block 6 is inclined.

[0038] An auxiliary plate 9 is fixedly connected to the surface of the connecting plate 4, and a stabilizing spring 10 which plays an elastic reset role is fixedly connected to the lower surface of the auxiliary plate 9, and the other side of the stabilizing spring 10 is fixedly connected to the surface of the stabilizing plate 7, and the stabilizing spring 10 is initially in a compressed state.

[0039] Initially, the top of the pressure block 6 is supported on the lower surface of the stabilizing plate 7. At this time, the stabilizing plate 7 is in a supported state. At this time, the socket 5 is not blocked, and it will not affect the staff's normal operation of plugging in the plug. When an external plug needs to be installed, the staff can normally install the plug into the socket 5. When installing the external plug, the external plug will push the pressure block 6 to move toward the inside of the connecting plate 4, and then the stabilizing plate 7 loses the supporting force of the pressure block 6, and then the stabilizing plate 7 moves under the action of the stabilizing spring 10 (moves toward the socket 5). Finally, the stabilizing plate 7 clamps the plug to facilitate the plug to remain stable. At this time, the stabilizing spring 10 makes the stabilizing plate 7 tend to move toward the socket 5, thereby optimizing the clamping stability. The stabilizing plates 7 are distributed on the upper and lower sides of the socket 5, so that the external plug is more stable when installed.

[0040] Embodiment 2: Different from Embodiment 1, the reset spring 11 is provided to facilitate the rapid return of the pressure block 6, thereby facilitating the next use of the pressure block 6. Figure 4 and Figure 5 As shown:

[0041] A limiting rod 8 is fixedly connected to the surface of the connecting plate 4, and the limiting rod 8 runs through the interior of the stabilizing plate 7, and the limiting rod 8 is an inverted "L" structure. A reset spring 11 that plays an elastic reset role is fixedly connected to the surface of the pressure block 6, and the other side of the reset spring 11 is fixedly connected to the inner wall of the connecting plate 4.

[0042] When installing an external plug and the pressure block 6 moves toward the inside of the connecting plate 4, the reset spring 11 will be squeezed. When the external plug needs to be removed, the stabilizing plate 7 is pushed away from the jack 5 so that the stabilizing plate 7 no longer squeezes the plug. After the plug is pulled out, the pressure block 6 loses the pressure of the external plug, and then the pressure block 6 returns to its original position under the action of the reset spring 11, that is, the pressure block 6 returns to the lower side of the stabilizing plate 7 again, and supports the stabilizing plate 7, so as to facilitate the next use of the stabilizing plate 7.

[0043] Embodiment 3: Different from Embodiment 2, the limit rod 8 is provided to limit the moving distance of the stabilizing plate 7, thereby ensuring stability. Figure 6 As shown:

[0044] The stabilizing plates 7 are symmetrically distributed about the center of the insertion hole 5 , and a baffle 12 is fixedly connected to the end of the limiting rod 8 .

[0045] During the movement of the stabilizing plate 7, the limiting rod 8 enables the stabilizing plate 7 to move only in the vertical direction, and the baffle 12 at the end of the limiting rod 8 limits the moving distance of the stabilizing plate 7, so that the stabilizing plate 7 will not fall during the movement, thereby ensuring stability.

[0046] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
