[0002] According to the published patent CN214373115U, the differential pressure sensor has a housing vent and a base plate vent. The sensor testing fixture has a mounting cavity, and the differential pressure sensor is mounted in the mounting cavity. The sensor testing fixture has a first air guide channel and a second air guide channel. The first air guide channel communicates with the housing vent, and the second air guide channel communicates with the base plate vent. The air guide direction of the first air guide channel is at least partially staggered with the air guide direction of the housing vent. This sensor testing fixture can reduce the entry of foreign objects into the differential pressure sensor during testing and improve the accuracy of the test results. However, it still has the following shortcomings:

[0003] After completion, the above equipment simply increases the accuracy of the test by ensuring the cleanliness of the inside of the sensor. However, since the temperature change is not obvious when testing the sensor, it cannot effectively test the working efficiency of the sensor under different environments, resulting in the problem of overly simplistic test data. Utility Model Content

[0004] The purpose of this invention is to provide a sensor temperature resistance testing fixture. By using a sinking mechanism and a positioning mechanism, it solves the problem that the working efficiency of the sensor under different environments cannot be effectively tested due to the insignificant temperature change when the sensor is being tested, resulting in overly simplistic test data.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a sensor temperature resistance testing fixture, including a storage box, a plurality of controllers are fixedly connected to the outer wall of the storage box, and a heating block is fixedly connected to the outer wall of the plurality of controllers.

[0007] The storage box has a sinking mechanism on its inner wall, which includes a water baffle. The outer wall of the water baffle is fixedly connected to the inner wall of the storage box. A placement plate is slidably connected to the outer wall of the water baffle. An extension plate is fixedly connected to the outer wall of the placement plate. Limiting holes are provided on the inner wall of the storage box. Several electric telescopic rods are fixedly connected to the top outer wall of the extension plate. Several positioning seats are fixedly connected to the top outer wall of the extension plate. Connecting rods are rotatably connected to the inner walls of the positioning seats. A support rod is rotatably connected to the outer wall of the connecting rod away from the positioning seat. A positioning block is fixedly connected to the outer wall of the other end of the support rod.

[0008] Furthermore, the outer wall of the positioning block is fixedly connected to the inner wall of the storage box, the outer wall of the electric telescopic rod is fixedly connected to the inner wall of the storage box, the outer wall of the extension plate is fixedly connected to the outer wall of the placement plate, the outer wall of the extension plate is slidably connected to the inner wall of the limiting hole, and the inner wall of the storage box is provided with a positioning mechanism.

[0009] Furthermore, the positioning mechanism includes a water-blocking shell, the outer wall of which is fixedly connected to the outer wall of the water-blocking plate, a bottom water-blocking box fixedly connected to the bottom outer wall of the water-blocking plate, a motor fixedly connected to the inner wall of the water-blocking shell, a connecting shaft fixedly connected to the output end of the motor via a coupling, and a gear fixedly connected to the bottom outer wall of the connecting shaft.

[0010] Furthermore, the outer wall of the gear is rotatably connected to the inner wall of the bottom water baffle box, the outer wall of the gear is meshed with several racks, the outer wall of the racks is slidably connected to the inner wall of the bottom water baffle box, and a fixing plate is fixedly connected to the top outer wall of the racks.

[0011] Furthermore, a plurality of first connecting blocks are fixedly connected to the outer wall of the fixed plate, and a first connecting rod is rotatably connected to the outer wall of the plurality of first connecting blocks. A slider is rotatably connected to the outer wall of the end of the first connecting rod away from the first connecting block.

[0012] Furthermore, a second connecting block is slidably connected to the inner wall of the fixing plate, a second connecting rod is rotatably connected to the inner wall of the second connecting block, and a rubber pressure plate is rotatably connected to the outer wall of the end of the second connecting rod away from the second connecting block.

[0013] Furthermore, a limiting groove is formed on the inner wall of the second connecting rod, the inner wall of the limiting groove is slidably connected to the outer wall of the slider, and a limiting rod is rotatably connected to the outer wall of the slider.

[0014] Furthermore, a number of dampers are fixedly connected to the outer wall of the limiting rod near the rubber pressure plate. The outer wall of the damper is fixedly connected to the outer wall of the rubber pressure plate, and a spring is fixedly connected to the outer wall of the damper.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates an electric telescopic rod and a placement plate. Once the liquid temperature reaches a specified level, the electric telescopic rod is activated to move the extension plate and simultaneously move the placement plate. This movement of the placement plate immerses all objects on its surface into the liquid. During the movement of the extension plate, the positioning seat moves, pulling the connecting rod. This causes the connecting rod to rotate around the positioning seat, moving the support rod and causing it to rotate around the positioning block. This achieves the goal of extending the placement plate into the heated liquid through the extension of the electric telescopic rod, preventing the problem of insufficient temperature change during sensor detection, which could lead to ineffective testing of sensor efficiency under different environments and overly simplistic test data.

[0017] 2. This utility model incorporates a fixed plate and a rubber pressure plate. Activating the motor inside the water-blocking housing causes the connecting shaft to rotate, simultaneously rotating the gears. Since the gears mesh with racks on both sides, the gears push the racks, moving the fixed plate within the water-blocking housing. This movement of the fixed plate pushes the second connecting block, causing the second connecting rods on both sides to move. These second connecting rods then move the rubber pressure plate, clamping the object in place. This achieves the goal of using the fixed plate to clamp the sensor, preventing collisions caused by vibrations during testing, which could lead to sensor displacement, data fluctuations, and increased testing costs.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a sensor temperature resistance testing fixture, including a storage box 1. Several controllers 101 are fixedly connected to the outer wall of the storage box 1. Heating blocks 102 are fixedly connected to the outer wall of the several controllers 101. The heating temperature of the heating blocks 102 is controlled by the controllers 101, and the liquid temperature inside the storage box 1 is displayed by the controllers 101.

[0029] The inner wall of the storage box 1 is provided with a sinking mechanism 2, which includes a baffle plate 201. The outer wall of the baffle plate 201 is fixedly connected to the inner wall of the storage box 1. A placement plate 202 is slidably connected to the outer wall of the baffle plate 201. The device on the surface of the placement plate 202 is moved by sliding the placement plate 202 along the surface of the baffle plate 201. An extension plate 205 is fixedly connected to the outer wall of the placement plate 202. Limiting holes 203 are formed in the inner wall of the storage box 1. Several electric telescopic rods 204 are fixedly connected to the top outer wall of the extension plate 205. The extension of the electric telescopic rods 204 pushes the extension plate 205 to move, thereby moving the placement plate 202. Several positioning seats 206 are fixedly connected to the top outer wall of the extension plate 205. A connecting rod 207 is rotatably connected to the inner wall. The connecting rod 207 rotates around the positioning seat 206 to assist the movement of the extension plate 205. A support rod 208 is rotatably connected to the outer wall of the end of the connecting rod 207 away from the positioning seat 206. A positioning block 209 is fixedly connected to the outer wall of the other end of the support rod 208. The outer wall of the positioning block 209 is fixedly connected to the inner wall of the storage box 1. The movement of the extension plate 205 is stabilized by the rotation of the support rod 208 around the positioning block 209, which pushes the connecting rod 207 to move. The outer wall of the electric telescopic rod 204 is fixedly connected to the inner wall of the storage box 1. The outer wall of the extension plate 205 is fixedly connected to the outer wall of the placement plate 202. The outer wall of the extension plate 205 is slidably connected to the inner wall of the limiting hole 203. A positioning mechanism 3 is provided on the inner wall of the storage box 1.

[0030] The positioning mechanism 3 includes a water-blocking housing 301, which protects objects on the surface of the placement plate 202. The outer wall of the water-blocking housing 301 is fixedly connected to the outer wall of the water-blocking plate 201. A bottom water-blocking box 306 is fixedly connected to the bottom outer wall of the water-blocking plate 201, which protects the parts at the bottom of the device and blocks liquid. A motor 302 is fixedly connected to the inner wall of the water-blocking housing 301. The motor 302 is started, and its output end is fixedly connected via a coupling. A connecting shaft 303 has a gear 304 fixedly connected to its bottom outer wall. The motor 302 drives the connecting shaft 303 to rotate, simultaneously causing the gear 304 to rotate. The outer wall of the gear 304 is rotatably connected to the inner wall of the bottom water-blocking box 306. Several racks 305 mesh with the outer wall of the gear 304. The outer walls of the racks 305 are slidably connected to the inner wall of the bottom water-blocking box 306. Through the meshing of the gear 304 with two racks 305, the gear 304 rotates and pushes the racks. 305 moves inside the bottom water-blocking box 306. A fixed plate 307 is fixedly connected to the top outer wall of the rack 305. Several first connecting blocks 308 are fixedly connected to the outer wall of the fixed plate 307. The movement of the rack 305 drives the fixed plate 307 to move inside the water-blocking shell 301. A first connecting rod 309 is rotatably connected to the outer wall of the several first connecting blocks 308. A slider 310 is rotatably connected to the outer wall of the first connecting rod 309 away from the first connecting block 308. The movement of the fixed plate 307 pushes the first connecting block 308, causing it to rotate around the first connecting block 308 and simultaneously pushing the slider 310 to move. A second connecting block 313 is slidably connected to the inner wall of the fixed plate 307. A second connecting rod 311 is rotatably connected to the inner wall of the second connecting block 313. A rubber pressure plate 317 is rotatably connected to the outer wall of the second connecting rod 311 away from the second connecting block 313. The movement of the fixed plate 307 pushes the second connecting rod 311, causing it to move the rubber pressure plate 317 closer to the object.

[0031] The inner wall of the second connecting rod 311 has a limiting groove 312. The inner wall of the limiting groove 312 is slidably connected to the outer wall of the slider 310. The slider 310 moves along the inside of the limiting groove 312, thereby changing the direction of movement of the second connecting rod 311. The outer wall of the slider 310 is rotatably connected to a limiting rod 314. Several dampers 315 are fixedly connected to the outer wall of the limiting rod 314 near the rubber pressure plate 317. The outer wall of the damper 315 is fixedly connected to the outer wall of the rubber pressure plate 317. A spring 316 is fixedly connected to the outer wall of the damper 315. The movement of the slider 310 drives the limiting rod 314 to move closer to the rubber pressure plate 317, thereby causing the limiting rod 314 to squeeze the damper 315 and the spring 316, thereby increasing the pressure of the rubber pressure plate 317 on the object.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, the device is placed on the surface of the baffle plate 201. Then, the baffle housing 301 is fixed to the outside of the baffle plate 201. The motor 302 inside the baffle housing 301 is then started, causing the connecting shaft 303 to rotate while simultaneously rotating the gear 304. Since the gear 304 meshes with the racks 305 on both sides, it pushes the racks 305, moving them while simultaneously moving the fixing plate 307 inside the baffle housing 301. The movement of the fixing plate 307 pushes the second connecting block 313, causing it to move the second connecting rods 311 on both sides, and thus the second connecting... Rod 311 moves the rubber pressure plate 317, clamping the object. Upon contact with the object, the object's movement causes the second connecting rod 311 to rotate around the rubber pressure plate 317, simultaneously pushing the second connecting block 313 to move within the fixed plate 307. This movement of the second connecting rod 311 moves the slider 310 inside, simultaneously pushing the first connecting rod 309 to rotate around the first connecting block 308. The first connecting rod 309 then pushes the slider 310 along the limiting groove 312. The movement of the slider 310 then pushes the limiting rod 314 to... Approaching the rubber pressure plate 317, and allowing the limiting rod 314 to press against the damper 315, the damper 315 is pre-set to automatically compress the spring 316 when compressed. This utilizes the elasticity of the spring 316 to increase the pressure on the rubber pressure plate 317. At this point, the object is fixed inside the water-blocking housing 301, and the bottom of the device is blocked by the bottom water-blocking box 306. Then, sufficient liquid is poured into the storage box 1, and the temperature of the heating block 102 is controlled by the controllers 101 on both sides. This allows the heating block 102 to heat the liquid inside the storage box 1, and the liquid temperature is displayed on the screen of the controller 101. Subsequently, after the liquid temperature reaches the specified temperature, the electric telescopic rod 204 is activated to push the extension plate 205 to move along the inside of the limiting hole 203, and to drive the placement plate 202 to move along the outside of the baffle plate 201. Thus, the movement of the placement plate 202 immerses all objects on its surface into the liquid. During the movement of the extension plate 205, the positioning seat 206 is moved while the connecting rod 207 is pulled. The connecting rod 207 rotates around the positioning seat 206 while driving the support rod 208 to move, and the support rod 208 rotates around the positioning block 209, thereby stabilizing the movement of the extension plate 205 and preventing shaking.
