Description

Technical Field

[0001] The utility model relates to the field of temperature detection equipment, and particularly relates to a rapid clamping device for temperature detection. Background Art

[0002] The refrigerant temperature is a very important factor in the air-conditioning system. It directly affects the working efficiency and refrigeration effect of the air-conditioning system. Too high temperature will cause harm such as overheating of the refrigeration compressor, serious wear, deterioration of lubricating oil, and decrease of refrigerating capacity, and at the same time increase the energy consumption of the system. Too low temperature is likely to cause harm such as decrease of refrigerating capacity of the refrigeration system and difficulty in oil return of the refrigeration compressor. Therefore, temperature measurement becomes particularly important in the R & D and test process of air-conditioning equipment. With the diversification of different units, more and more temperature points need to be measured in the air-conditioning system, and temperature sensors need to be installed at these temperature points for detection.

[0003] In the prior art, it often relies on operators to manually install temperature sensors, which is not only time-consuming and laborious, with low installation efficiency, but also has the problem of inaccurate temperature measurement caused by manual installation. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies existing in the prior art, and provide a rapid clamping device for temperature detection, which can quickly, stably and accurately install the temperature sensor on the pipeline to be installed, realize the rapid installation during the temperature sensor test, avoid the error caused by manual installation and heat preservation, improve the data accuracy, effectively shorten the process time-consuming, reduce the man-hour cost and improve the production efficiency.

[0005] The purpose of the utility model is completed by the following technical solutions: This rapid clamping device for temperature detection includes a clamp body, a heat preservation and heat equalizing plate and a return spring. A return spring is arranged at the tail of the clamp body, so that when the tail is pressed, the head of the clamp body opens relatively, and when the tail is released, the head closes relatively. Grooves are respectively opened on the opposite surfaces at the upper and lower ends of the head for detachably installing the heat preservation and heat equalizing plate. The back of the heat preservation and heat equalizing plate is a back plate, and a cylindrical flange is arranged on the back plate for being clamped into the corresponding groove. A layer of heat-conducting aluminum foil paper is arranged on the opposite surfaces of the two heat preservation and heat equalizing plates, and a heat preservation layer is arranged between the heat-conducting aluminum foil paper and the back plate.

[0006] As a further technical solution, the cross-section of the heat preservation and heat equalizing plate is arc-shaped and matches the surface of the copper pipe to be measured.

[0007] As a further technical solution, the size of the heat preservation and heat equalizing plate matches the specification of the copper pipe to be measured.

[0008] As a further technical solution, when the heat preservation and heat equalizing plate is attached to the surface of the copper pipe to be measured, the cylindrical flange rotates relatively in the groove.

[0009] As a further technical solution, the heat insulation layer is made of elastic heat insulation cotton and is bonded to the back plate by glue, and the heat-conducting aluminum foil paper is bonded to the heat insulation layer by glue.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Using the heat insulation and heat equalizing sheet to insulate the detection temperature probe and increase the detection area, not only reduces the error caused by the interference of the external temperature on the detected temperature of the sensor, but also increases the detection area of the detection temperature probe, reduces the inaccuracy of the temperature test caused by manual installation, and greatly reduces the error of the temperature test device during the test process;

[0012] 2. The heat insulation and heat equalizing plate and the clamping body are in concave-convex fit through a cylindrical structure, so that when the device is clamped on the surface of the copper pipe to be measured, it can be adjusted by a small amount of rotation to ensure clamping, effectively shortening the process time-consuming, reducing the labor cost, and improving the production efficiency.

[0016] The following will introduce the present utility model in detail with reference to the drawings:

[0017] Embodiment: As shown in the attached Figure 1 、 2 figures, this kind of rapid clamping device for temperature detection includes a clamping body 1, a head 11, a groove 111, a tail 12, a heat insulation and heat equalizing plate 2, a back plate 21, a cylindrical flange 22, a heat-conducting aluminum foil paper 23, a heat insulation layer 24 and a return spring 3.

[0018] Refer to the attached Figure 1, a return spring 3 is provided at the tail 12 of the clip body 1, so that when the tail 12 is pressed, the head 11 of the clip body 1 opens relatively, and when the tail 12 is released, the head 11 closes relatively; on the opposite surfaces of the upper and lower ends of the head 11, a groove 111 (semicircular in cross-section) is provided, and a heat-insulating and heat-uniforming plate 2 is detachably installed in the groove 111. The back surface of the heat-insulating and heat-uniforming plate 2 is a back plate 21, and a cylindrical flange 22 is provided at the middle position of the back plate 21, which can be clamped into the corresponding groove 111. A layer of heat-conducting aluminum foil paper 23 is provided on the opposite surfaces of the two heat-insulating and heat-uniforming plates 2, and a heat-insulating layer 24 is provided between the heat-conducting aluminum foil paper 23 and the back plate 21. The heat-insulating layer 24 is made of elastic heat-insulating cotton and is bonded to the back plate 21 with glue, and the heat-conducting aluminum foil paper 23 is bonded to the heat-insulating layer 24 with glue. The clip body 1 is made of plastic parts.

[0019] Preferably, the heat-conducting aluminum foil paper 23 can also be made of other materials with good heat-conducting performance and is mutually attached to the heat-insulating cotton, which can expand the detection range of the temperature probe, reduce the particularity of the temperature measurement points, and ensure the accuracy of temperature detection. One side of the heat-insulating layer 24 is attached to the heat-conducting aluminum foil paper 23, and the other side is attached to the back plate 21, which can prevent the interference of the external temperature on the detection of the temperature probe and improve the accuracy of the temperature probe detection.

[0020] Furthermore, the cross-section of the heat-insulating and heat-uniforming plate 2 is arc-shaped and matches the surface of the copper pipe to be measured. The size of the heat-insulating and heat-uniforming plate 2 matches the specification of the copper pipe to be measured, and it is adapted and replaced according to the copper pipe to be measured before testing.

[0021] Since the heat-insulating and heat-uniforming plate 2 and the clip body 1 are in concave-convex fit through a cylindrical structure, when the device is clamped on the surface of the copper pipe to be measured, that is, when the heat-insulating and heat-uniforming plate 2 is in contact with the surface of the copper pipe to be measured, a small rotation adjustment can be made (the cylindrical flange 22 rotates relatively in the groove 111) to ensure clamping.

[0022] The working process of the present utility model:

[0023] The corresponding replaceable heat-insulating and heat-uniforming plate 2 is installed at the groove 111 of the front head 11 of the clip body 1. The heat-insulating and heat-uniforming plate 2 can be selected or replaced according to the size of the copper pipe and the wear condition of the heat-insulating and heat-uniforming layer. When the return spring 3 releases the tail 12 of the clip body, it provides a fastening force for the clip body 1 to clamp the temperature detection wire and the measured temperature point, so that the detected temperature can be more accurate. When measuring the temperature, select a replaceable heat-insulating and heat-uniforming plate 2 with a suitable size and connect it to the clip body 1 through the groove 111. Then pinch the tail 12 of the clip body 1, and the clip head part will open. Then paste the temperature detection wire on the heat-conducting aluminum foil paper of the replaceable heat-insulating and heat-uniforming plate 2, align the clip head with the position to be measured, and release the tail of the clip body. The clip head is clamped on the surface of the copper pipe to be measured under the action of the return spring 3.

[0024] Appendix Figure 2The middle backplane 21 is the bottom plate of the heat-insulating vapor chamber 2, providing installation conditions for the heat-insulating layer 24 and the heat-conducting aluminum foil 23. The cylindrical flange 22 provides conditions for quick disassembly and quick installation of the heat-insulating vapor chamber 2, and provides a small-angle rotation for it, facilitating the better fitting of the heat-insulating vapor chamber 2 to the measured surface. The heat-conducting aluminum foil 23 is a kind of metal aluminum foil, which is pasted on the heat-insulating layer 24 through the glue on the back. The heat-insulating layer 24 is a layer of elastic heat-insulating cotton, which is adhered to the backplane 21 through the glue on the back.
