[0030] As Figures 1-3 shown, a high and low temperature alternating damp heat test chamber for high temperature resistant tapes includes a test chamber body 1, and a plurality of universal wheels 2 are evenly connected below the test chamber body 1. This enables the entire test chamber to be easily moved and positioned, improving the utilization rate of the test site and the flexibility of the equipment. A placing tray 5 is slidably connected inside the test chamber body 1, and a chamber door 3 is rotatably connected to the test chamber body 1; an observation window 4 is opened on the chamber door 3. It is possible to observe the changes of the test samples in real time through the observation window 4 on the chamber door 3 during the test, without frequently opening the chamber door 3, ensuring the safety of the test.

[0031] The placing tray 5 is slidably connected to the test chamber body 1 through a sliding block 6. The test chamber body 1 is correspondingly provided with a sliding groove 7. A first lead screw 8 is rotatably connected inside the sliding groove 7. The sliding block 6 is threadedly connected to the first lead screw 8. A first driving motor 9 drives the first lead screw 8 to rotate, and the first driving motor 9 is fixedly connected inside the test chamber body 1;

[0032] A connecting plate 10 is longitudinally and slidably connected in a placement tray 5 through a lifting assembly. A plurality of guide rods 23 are evenly connected to the placement tray 5, and the connecting plate 10 is provided with guide grooves 24 corresponding to the guide rods 23. A test plate 11 is connected to the connecting plate 10; a handle 12 is connected to the end of the test plate 11. The test plate 11 together with the high-temperature resistant tape can be taken out from the connecting plate 10 through the handle 12. A plurality of clamping members 21 are connected to the connecting plate 10 corresponding to the test plate 11, and grooves 22 are provided in the test plate 11 corresponding to the clamping members 21. This ensures the stability of the test plate 11 during the test and prevents the test sample from moving or falling off during the test.

[0033] As Figure 4 shown, the lifting assembly includes a first connecting rod 13 and a second connecting rod 14. Both the first connecting rod 13 and the second connecting rod 14 are rotatably connected to the connecting plate 10.

[0034] The working process of the present utility model is as follows:

[0035] When placing the high-temperature resistant tape into the test chamber body 1: First, place the high-temperature resistant tape to be tested on the test plate 11 on the connecting plate 10, and fix it through the clamping member 21 and the groove 22 to ensure that the high-temperature tape will not fall off during the test. Then, start the first driving motor 9 to drive the first lead screw 8 to rotate forward, so that the sliding block 6 moves in the sliding groove 7, thereby driving the placement plate 5 into the test chamber body 1. At the same time, the gear 18 and the rack 20 are in a meshing state, and the gear 18 moves on the rack 20. Then, the gear 18 drives the bidirectional lead screw to rotate, and the first displacement block 15 and the second displacement block 16 move along the bidirectional lead screw 17 towards both ends, thereby driving the connecting plate 10 and the test plate 11 to descend. Then, close the door 3 to ensure the airtightness and stability of the environment inside the test chamber. Then, start the test chamber to start working according to the set parameters. The temperature and humidity inside the test chamber are adjusted through heating, refrigeration, humidification and other systems to simulate various environmental conditions that the high-temperature resistant tape may encounter.

[0036] When placing the high-temperature resistant tape into the test chamber body 1: When the test reaches the predetermined time, the test chamber stops working. Then, open the door 3, start the first driving motor 9 to drive the first lead screw 8 to rotate reversely, so that the sliding block 6 moves in the sliding groove 7, thereby driving the placement plate 5 to slide out of the test chamber body 1. At the same time, the gear 18 and the rack 20 are in a meshing state, and the gear 18 moves on the rack 20. Then, the gear 18 drives the bidirectional lead screw to rotate, and the first displacement block 15 and the second displacement block 16 move along the bidirectional lead screw 17 towards the middle, thereby driving the connecting plate 10 and the test plate 11 to rise. The test plate 11 is separated from the placement plate 5. Then, take out the test plate 11 together with the high-temperature resistant tape from the connecting plate 10 through the handle 12.
