[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] A high-temperature resistance testing device for sealants is used to evaluate the performance stability and temperature resistance of sealants in high-temperature environments. This device is particularly suitable for applications requiring evaluation of sealant performance under extreme temperatures, such as sealing applications in building materials, transportation, electronic instruments, and components. High-temperature resistance testing of sealants is crucial for ensuring the performance and safety of products in high-temperature environments. This testing helps prevent potential product failures, improves product reliability, and increases user confidence.

[0021] Please see Figures 1-5 As shown, this embodiment provides a high-temperature resistance testing device for sealant, including a main body 1 and a base plate 11. After high-temperature heating, it is inconvenient for users to immediately test the sealant's performance. Removing the sealant from the oven before testing affects the continuity of the testing process, and the freshly heated sealant may burn the user. Therefore, specifically: a testing component 2 is provided above the base plate 11. The testing component 2 is used to test the performance of the sealant after the high-temperature resistance test. The testing component 2 includes a testing plate 22 and a sliding plate 23, wherein:

[0022] Two sliding plates 23 slide horizontally above the test plate 22. The sliding test plate 22 is on the outer wall of the sliding groove 221. The two sliding plates 23 record the initial length of the sealant. The sealant is compared with the two sliding plates 23. If the lengths match, the sealant has good volume shrinkage performance and is a qualified product. If the length of the sealant is incorrect, the high temperature resistance test of the sealant is unqualified.

[0023] The improvement in this embodiment is as follows:

[0024] Place the sealant in its initial state on top of the test plate 22, and slide the two sliding plates 23 to measure the length of the sealant. After completing the high temperature resistance test of the sealant, use the two sliding plates 23 again to compare the sealant. If the length of the sealant is not in error with the initial record, the sealant has good performance.

[0025] To facilitate direct performance testing of the sealant by users, a mounting block 20 is provided above the base plate 11. A fixing rod 21 is fixedly connected above the mounting block 20. A test plate 22 is slidably connected to the outer wall of the fixing rod 21. Two sliding grooves 221 are symmetrically provided on the surface of the test plate 22. Sliding plates 23 are slidably connected to the inner walls of the two sliding grooves 221. A placement plate 24 is fixedly connected to the upper end of the fixing rod 21. The sealant to be tested is placed on the placement plate 24. The test plate 22 is slid on the outer wall of the sliding groove 221, with the upper part of the test plate 22 adhering to the lower part of the sealant. The two sliding plates 23 are slid on the inner wall of the sliding groove 221, with the outer sides of the two sliding plates 23 tightly adhering to both ends of the sealant. The two sliding plates 23 record the initial length of the sealant. The main body 1 of the high-temperature sealant testing device is opened to conduct a high-temperature test on the sealant. After the test is completed, the test plate 22 is rotated and brought closer to the sealant. The two sliding plates 23 are used to compare the sealant.

[0026] Considering that the sealant is not stable enough when placed above the placement plate 24, the upper surface of the placement plate 24 is provided with a groove 241. The inner wall of the groove 241 is rotatably connected to a first bidirectional lead screw 25. The outer wall of the first bidirectional lead screw 25 is symmetrically rotatably connected to two locking blocks 251. The outer walls of the two locking blocks 251 slide on the inner wall of the groove 241. A clamping plate 252 is fixedly connected above the two locking blocks 251. A rotating cap 253 is fixedly connected to the end of the first bidirectional lead screw 25. The rotating cap 253 drives the first bidirectional lead screw 25 to rotate on the inner wall of the groove 241. The rotation of the first bidirectional lead screw 25 drives the two symmetrical locking blocks 251 on the outer wall to slide in opposite directions on the inner wall of the groove 241. The locking blocks 251 drive the clamping plate 252 to clamp and fix the outer wall of the sealant, thus fixing the sealant.

[0027] Considering the need to test the hardness change of the sealant, the upper surface of the mounting block 20 is provided with a moving groove 201. A second bidirectional lead screw 26 is rotatably connected to the inner wall of the moving groove 201. Two moving blocks 261 are symmetrically rotatably connected to the outer wall of the second bidirectional lead screw 26. The outer walls of the two moving blocks 261 slide against the inner wall of the moving groove 201. A moving rod 262 is fixedly connected above each of the two moving blocks 261. A rotating block 263 is fixedly connected to the end of the second bidirectional lead screw 26. A fixing plate 27 is fixedly connected to the upper end of the moving rod 262. A side plate 271 is fixedly connected above the fixing plate 27. A threaded rod 28 is threadedly connected to the inner wall of the side plate 271. A pressing plate 28 is rotatably connected to one end of the threaded rod 28. 81. The extrusion plate 281 slides below the fixed plate 27. The other end of the threaded rod 28 is fixedly connected to the rotating plate 282. The rotating block 263 drives the second bidirectional screw 26 to rotate on the inner wall of the moving groove 201, which drives the two moving blocks 261 on the outer wall to move in opposite directions. The two moving blocks 261 drive the moving blocks 261 to move synchronously, adjusting the fixed plate 27 to below the sealant. The two rotating plates 282 are rotated, and the rotating plates 282 drive the threaded rod 28 to rotate on the inner wall of the side plate 271. The threaded rod 28 drives the extrusion plate 281 to clamp the two ends of the sealant. After fixing the two ends of the sealant, the moving rod 262 is rotated in the opposite direction, so that the two fixed plates 27 pull the sealant for hardness comparison.

[0028] Considering that the sealant being inside the main body 1 of the high-temperature sealant testing device is inconvenient for users to conduct performance tests and poses a risk of burns, a cavity is provided inside the base plate 11. An electric telescopic rod 29 is fixedly installed on the inner wall of the cavity, and a connecting block 291 is fixedly connected to the end of the electric telescopic rod 29. An open slide groove 111 is provided on the upper surface of the base plate 11. The outer wall of the connecting block 291 slides to fit the inner wall of the open slide groove 111. The upper part of the connecting block 291 is fixedly connected to the lower part of the mounting block 20. The electric telescopic rod 29 drives the connecting block 291 to slide on the inner wall of the open slide groove 111 on the upper surface of the base plate 11. The connecting block 291 drives the mounting block 20 to move, moving the entire test component 2 to the outside of the main body 1 of the high-temperature sealant testing device, preventing users from being burned by the high temperature inside the main body 1 of the high-temperature sealant testing device.

[0029] In summary, the working principle of this solution is as follows:

[0030] In practical use, the sealant high-temperature resistance testing device of this utility model is used by placing the sealant to be tested above the placement plate 24, rotating the rotating cap 253, which drives the first bidirectional lead screw 25 to rotate on the inner wall of the groove 241. The rotation of the first bidirectional lead screw 25 drives the two symmetrical locking blocks 251 on the outer wall to slide in opposite directions on the inner wall of the groove 241. The locking blocks 251 drive the clamping plate 252 to clamp and fix the outer wall of the sealant. After fixing the sealant, the sliding test plate 22 is placed on the outer wall of the sliding groove 221, with the upper part of the test plate 22 attached to the lower part of the sealant. The two sliding blocks 251 are then used to clamp and fix the sealant. Two sliding plates 23 are placed on the inner wall of the sliding groove 221. The outer sides of the two sliding plates 23 are pressed tightly against the two ends of the sealant. The two sliding plates 23 record the initial length of the sealant. The test plate 22 is rotated on the outer wall of the fixed rod 21, so that the sliding plates 23 are away from the sealant. The main body 1 of the high-temperature test device for sealant is opened to conduct a high-temperature test on the sealant. After the test is completed, the electric telescopic rod 29 is opened. The electric telescopic rod 29 drives the connecting block 291 to slide on the inner wall of the open sliding groove 111 on the upper surface of the base plate 11. The connecting block 291 drives the mounting block 20 to move, moving the test assembly 2 as a whole. To prevent burns from the high temperature inside the sealant high-temperature testing device 1, the test plate 22 is rotated and brought closer to the sealant. Two sliding plates 23 are used to compare the sealant. If the lengths match, the sealant has good volume shrinkage performance and is a qualified product. If the sealant length is incorrect, the high-temperature resistance test is unqualified. The rotating block 263 is then rotated, causing the second bidirectional lead screw 26 to rotate on the inner wall of the moving groove 201, which in turn causes the two moving blocks 261 on the outer wall to move in opposite directions. The movable block 261 moves synchronously, adjusting the fixed plate 27 to be below the sealant. The two rotating plates 282 are rotated, causing the threaded rod 28 to rotate on the inner wall of the side plate 271. The threaded rod 28 drives the extrusion plate 281 to clamp the two ends of the sealant. After fixing the two ends of the sealant, the movable rod 262 is rotated in the opposite direction, causing the two fixed plates 27 to pull the sealant for hardness comparison. After pulling, the sealant is loosened, and the length of the sealant is compared again to evaluate whether the sealant has performance problems such as hardness change or volume shrinkage under long-term high temperature.
