Description

Technical Field

[0001] This utility model relates to the field of sensor detection technology, and in particular to a temperature sensor detection device. Background Technology

[0002] Temperature sensors are devices that convert the physical quantity of temperature into an electrical signal output. Their core function is to sense and transmit temperature information, providing basic data for temperature monitoring, control, and early warning. They are widely used in industries, medical fields, and home applications. During the manufacturing process, it is usually necessary to test their strength because temperature sensors often operate in complex environments such as vibration, impact, high temperature, and high pressure. Insufficient strength may lead to structural damage, measurement failure, or even equipment failure or safety accidents. Testing their strength can ensure that they operate stably and reliably in actual working conditions.

[0003] For example, CN219368983U discloses a temperature sensor detection device, including a bottom plate and a fixed base. The fixed base is located on one side of the top of the bottom plate, and a drive motor is located at the top of the fixed base. A fixed block is located on one side of the fixed base, and a fixed column is located at the top of the fixed block near the fixed base. A top plate is located at the top of the fixed column, and a bidirectional threaded rod is rotatably connected to the top plate. A driven wheel is fixed to the top of the bidirectional threaded rod extending out of the top plate. A first clamping plate and a second clamping plate are threaded onto the bidirectional threaded rod, respectively. The fixing mechanism can fix multiple sets of temperature controllers, and the fixing mechanism can be disassembled as needed.

[0004] However, in the existing technology, when performing strength testing on thermostats, the thermostats come in various sizes and the existing fixing devices lack universality. Each size requires a corresponding exclusive fixing device, and when replacing them, the original device must be disassembled and the new device installed and debugged. The process is complicated and inconvenient, which increases the testing time and labor costs and reduces efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a temperature sensor detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temperature sensor detection device, including a detection platform, a pressurizing mechanism fixedly connected to the upper part of the detection platform, and a placement mechanism installed on the surface of the detection platform, the placement mechanism being located below the pressurizing mechanism, the pressurizing mechanism including a fixed frame, a hydraulic cylinder installed on the upper part of the fixed frame, a pressure sensor fixedly connected to the bottom of the hydraulic cylinder, a pressurizing head installed below the pressure sensor, the placement mechanism including a base, an mounting seat fixedly connected to the upper part of the base, a placement mold inserted inside the mounting seat, and a mounting bracket fixedly connected to the side of the mounting seat, a pull rod inserted into the surface of the mounting bracket, and a wedge-shaped insert fixedly connected to the end of the pull rod, the wedge-shaped insert being inserted into the side of the mounting seat and the placement mold respectively.

[0007] Preferably, a limit rod is fixedly connected to the upper part of the pressure head, and the limit rod is slidably inserted into the fixed frame.

[0008] Preferably, a first spring is provided on the surface of the pull rod, one end of the first spring is fixedly connected to the wedge-shaped insert, and the other end of the first spring is fixedly connected to the surface of the mounting bracket.

[0009] Preferably, a telescopic rod is fixedly connected to the surface of the testing table, a connecting plate is fixedly connected to the top of the telescopic rod, and a second spring is provided on the surface of the telescopic rod. One end of the second spring is fixedly connected to the testing table, and the other end of the second spring is fixedly connected to the connecting plate. The connecting plate is in contact with the bottom of the mold.

[0010] Preferably, the bottom of the mounting base and the top of the base are provided with through holes, and the upper parts of the telescopic rod and the second spring are located inside the through holes.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by setting up a placement mechanism, different models of placement molds can be inserted into the mounting base. With the help of the pull rod, wedge-shaped insert, and spring No. 1 on the mounting frame, the placement mold can be quickly fixed and replaced. When the placement mold is inserted, it squeezes the wedge-shaped insert outward. After it is in place, the spring No. 1 pushes the wedge-shaped insert into the mounting base and fixes it to the placement mold. When replacing, the pull rod can be pulled out to remove the wedge-shaped insert and take off the mold. There is no need for complicated disassembly and adjustment, which solves the problem of different sizes of thermostats needing dedicated fixing devices. At the same time, the hydraulic cylinder in the pressurization mechanism pushes the pressure head with pressure sensor to apply pressure, and the limit rod ensures stable pressure. Combined with the appropriate placement mold, the strength test of thermostats of different sizes can be completed efficiently, which greatly reduces time and labor costs and improves testing efficiency.

[0013] 2. In this utility model, the replacement process of the placement mold is further optimized by using the telescopic rod fixed on the surface of the testing table, the connecting plate connected to its top, and the No. 2 spring on the surface. During installation, the placement mold presses down on the connecting plate, causing the telescopic rod and the No. 2 spring to compress and deform. During replacement, after the wedge-shaped insert is released from its fixed position, the telescopic rod and the No. 2 spring return to their original deformation, pushing the placement mold upward. This eliminates the need for manual labor to remove the mold, significantly improving the convenience of replacement and further reducing operation time. Attached Figure Description

Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4 As shown, this utility model provides a temperature sensor detection device, including a detection platform 1. A pressurizing mechanism 2 is fixedly connected to the upper part of the detection platform 1, and a placement mechanism 3 is installed on the surface of the detection platform 1. The placement mechanism 3 is located below the pressurizing mechanism 2. The pressurizing mechanism 2 includes a fixing frame 21, a hydraulic cylinder 22 is installed on the upper part of the fixing frame 21, a pressure sensor 23 is fixedly connected to the bottom of the hydraulic cylinder 22, and a pressure head 24 is installed on the lower part of the pressure sensor 23. The placement mechanism 3 includes a base 31, a mounting seat 32 is fixedly connected to the upper part of the base 31, and a mounting seat 32 is inserted into the mounting seat 32. A mold 33 is placed, and a mounting bracket 34 is fixedly connected to the side of the mounting base 32. A pull rod 35 is inserted into the surface of the mounting bracket 34, and a wedge-shaped plug 36 is fixedly connected to the end of the pull rod 35. The wedge-shaped plug 36 is inserted into the side of the mounting base 32 and the mold 33 respectively. A limit rod 25 is fixedly connected to the upper part of the pressure head 24. The limit rod 25 is slidably inserted into the fixing bracket 21. A first spring 37 is provided on the surface of the pull rod 35. One end of the first spring 37 is fixedly connected to the wedge-shaped plug 36, and the other end of the first spring 37 is fixedly connected to the surface of the mounting bracket 34.

[0022] The specific settings and functions of this embodiment are described below. When using this utility model, the appropriate placement mold 33 is selected based on the model of the temperature sensor required for pressure testing. The placement mold 33 is inserted into the mounting base 32 for fixation. During the insertion process, the wedge-shaped surface of the wedge-shaped insert 36 is subjected to pressure and moves outward from the mounting base 32. When the placement mold 33 is in place, the first spring 37 restores its deformation and pushes the wedge-shaped insert 36 to be inserted and fixed with the mounting base 32 and the placement mold 33, which facilitates the quick installation and fixation of the placement mold 33. When replacing the placement mold 33, the pull rod 35 is pulled to pull the end of the wedge-shaped insert 36 out from the side of the placement mold 33, and the placement mold 33 can be removed for replacement.

[0023] The temperature sensor is placed in the placement mold 33, and the pressure sensor 23 and the pressure head 24 are pushed downward by the hydraulic cylinder 22 to pressurize and detect the temperature sensor.

[0024] By setting up a placement mechanism 3, in which different models of placement molds 33 can be inserted into the mounting base 32, and with the pull rod 35, wedge-shaped insert 36 and spring 37 on the mounting bracket 34, the placement mold 33 can be quickly fixed and replaced. When the placement mold 33 is inserted, it squeezes the wedge-shaped insert 36 outward. After it is in place, the spring 37 pushes the wedge-shaped insert 36 into the mounting base 32 and the placement mold 33 to complete the fixation. When replacing, the pull rod 35 can be pulled out to remove the wedge-shaped insert 36 and take off the mold. There is no need for complicated disassembly and debugging, which solves the problem that different sizes of thermostats need dedicated fixing devices. At the same time, the hydraulic cylinder 22 in the pressurization mechanism 2 pushes the pressure head 24 with pressure sensor 23 to apply pressure. The limit rod 25 ensures stable pressure. Combined with the appropriate placement mold 33, the strength test of thermostats of different sizes can be completed efficiently, which greatly reduces time and labor costs and improves the testing efficiency.

[0025] Example 2: Figure 4 As shown, a telescopic rod 38 is fixedly connected to the surface of the testing table 1, and a connecting plate 310 is fixedly connected to the top of the telescopic rod 38. A second spring 39 is provided on the surface of the telescopic rod 38. One end of the second spring 39 is fixedly connected to the testing table 1, and the other end of the second spring 39 is fixedly connected to the connecting plate 310. The connecting plate 310 fits against the bottom of the mold 33. The bottom of the mounting base 32 and the top of the base 31 are both provided with through holes. The upper parts of the telescopic rod 38 and the second spring 39 are both located inside the through holes.

[0026] The overall effect of this embodiment is that during the installation of the placement mold 33, the connecting plate 310 is subjected to downward pressure. At this time, the telescopic rod 38 and the second spring 39 undergo compression deformation. When the placement mold 33 is replaced, after the wedge-shaped insert 36 is released from the insertion of the placement mold 33, the telescopic rod 38 and the second spring 39 restore their deformation and push the placement mold 33 to move upward.

[0027] The replacement process of the placement mold 33 is further optimized by using the telescopic rod 38 fixed on the surface of the testing table 1, the connecting plate 310 connected to its top, and the second spring 39 on the surface. During installation, the placement mold 33 presses down on the connecting plate 310, causing the telescopic rod 38 and the second spring 39 to compress and deform. During replacement, after the wedge-shaped insert 36 is released from its fixed position, the telescopic rod 38 and the second spring 39 return to their original deformation, pushing the placement mold 33 upward. This eliminates the need for manual labor to remove the mold, significantly improving the convenience of replacing the placement mold 33 and further reducing operation time.

[0028] To improve detection efficiency, the following is the usage and working principle of this device: When using this utility model, select a suitable placement mold 33 according to the model of the temperature sensor to be tested for pressure resistance. Insert the placement mold 33 into the mounting base 32 for fixation. During the insertion process, the wedge-shaped surface of the wedge-shaped insert 36 is subjected to pressure and moves to the outside of the mounting base 32. When the placement mold 33 is inserted into place, the first spring 37 returns to its original deformation and pushes the wedge-shaped insert 36 to be inserted and fixed with the mounting base 32 and the placement mold 33, which facilitates the quick installation and fixation of the placement mold 33. When replacing the placement mold 33, pull the pull rod 35 to pull the end of the wedge-shaped insert 36 out from the side of the placement mold 33, and the placement mold 33 can be removed for replacement.

[0029] During the installation of the placement mold 33, the connecting plate 310 is subjected to downward pressure. At this time, the telescopic rod 38 and the second spring 39 undergo compression deformation. When the placement mold 33 is replaced, after the wedge-shaped insert 36 is released from the insertion of the placement mold 33, the telescopic rod 38 and the second spring 39 restore their deformation, pushing the placement mold 33 to move upward, thus making it easier to replace the placement mold 33.

[0030] The temperature sensor is placed in the placement mold 33, and the pressure sensor 23 and the pressure head 24 are pushed downward by the hydraulic cylinder 22 to pressurize and detect the temperature sensor.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
