Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature test boxes, in particular to a shock-absorbing and sealing structure of a high-temperature test box. Background Art

[0002] In modern industrial production and scientific research, high temperature test chambers are widely used in performance testing of various materials and products. High temperature test chambers usually need to operate in a high temperature environment to simulate usage under various extreme conditions.

[0003] There are some problems in the use of existing high-temperature test chambers. On the one hand, since the high-temperature test chamber will generate large vibrations during operation, these vibrations will not only affect the stability of the test environment inside the test chamber, but may also interfere with the surrounding equipment and working environment. On the other hand, the sealing performance of the high-temperature test chamber is also crucial. If the sealing is poor, it will not only cause heat loss and affect the temperature control accuracy of the test chamber, but may also allow external impurities to enter the test chamber and affect the accuracy of the test results. Therefore, a shock-absorbing sealing structure for a high-temperature test chamber is proposed. Summary of the Invention

The side sleeve is connected with a spring 2 12, a fixing frame 13 is provided under the base 1, the upper end of the base 1 is fixedly connected to a test box body 14, a test groove 15 is provided at the front end of the test box body 14, a sealing gasket 16 is fixedly connected to the front end of the test box body 14, a sealing ring 17 is provided at the front end of the sealing gasket 16, a sealing door 18 is rotatably connected to the front end of the test box body 14, a groove 19 and a groove 20 are provided at the rear end of the sealing door 18, a convex edge 21 is fixedly connected to the rear end of the groove 19, a lock assembly 22 is fixedly connected to the front end of the test box body 14, a rotary lock assembly 23 is fixedly connected to the front end of the sealing door 18, and a buffer block 3 24 is fixedly connected to the lower end of the movable frame 2 7;

[0032] The buffer assembly 1 4 includes a hydraulic lifting rod 401 and a spring 1 402. The outer side of the hydraulic lifting rod 401 is sleeved with the spring 1 402.

[0033] The lock assembly 22 includes a fixing seat 2201, a slot 2202 and a screw 2203. The front end of the fixing seat 2201 is fixedly connected to the slot 2202, and the front end of the slot 2202 is provided with a screw 2203;

[0034] The rotating lock assembly 23 includes a second fixing seat 2301, a rotating handle 2302, a locking piece 2303 and a locking groove 2304.

[0035] Specifically, slide bar 2 is slidably connected to movable frame 3, and buffer assembly 4 has the same structure as buffer assembly 2 8. The advantage of providing slide bar 2 is that when the test chamber body 14 is subjected to left-right forces, the base 1 and movable frame 3 slide relative to each other, slide bar 2 slides along movable frame 3, and buffer assembly 4 buffers the force.

[0036] Specifically, the movable frame 2 7 and the slide bar 2 6 are slidably connected, and the central axis of the slide bar 2 6 is perpendicular to the central axis of the slide bar 1 2. Advantageously, when the test chamber body 14 is subjected to a front-to-back force, the base 1 and the movable frame 2 7 slide relative to each other, the slide bar 2 6 slides along the movable frame 2 7, and the buffer assembly 2 8 buffers the force.

[0037] Example 2: Figure 2-5 As shown, it is an improvement to the previous embodiment.

[0038] Specifically, buffer blocks 1 5 , 2 9 , and 3 24 are all made of fluororubber. Fixed rod 10 and fixed frame 13 are slidably connected, and the ends of spring 2 12 are fixedly connected to movable frame 2 7 and fixed frame 13, respectively. Advantageously, buffer blocks 1 5 and 2 9 , made of fluororubber, are highly weather-resistant and, in conjunction with buffer components 1 4 and 2 8 , enhance shock absorption. When the test chamber body 14 is subjected to vertical forces, fixed rod 10 slides along fixed frame 13, and spring 2 12 and buffer block 3 24 cushion the force. This multi-component collaboration enhances the shock absorption performance of the test chamber body 14, improving its operational stability.

[0039] Specifically, the sealing gasket 16 fits into the first groove 19, and the sealing ring 17 fits into the second groove 20. The advantage is that, when the sealing door 18 is closed, the sealing gasket 16 enters the first groove 19, and the sealing ring 17 enters the second groove 20. The convex edge 21 squeezes the sealing gasket 16, causing it to deform and fill the first groove 19, thereby increasing the sealing length and improving the sealing effect.

[0040] Specifically, the slot 2202 is adapted to the locking piece 2303. The advantage is that the door 18 can be tightly sealed to the test box body 14 through the lock assembly 22 and the rotary lock assembly 23.

[0041] Specifically, the screw rod 2203 is threadedly connected to the slot 2202, and the screw rod 2203 is adapted to the locking groove 2304. The advantage is that after the sealing door 18 is closed, the handle 2302 is rotated to insert the locking piece 2303 into the slot 2202 and contact the bottom end of the slot 2202. The screw rod 2203 is rotated to insert the screw rod 2203 into the locking groove 2304, locking the locking piece 2303 and applying pressure to the locking piece 2303, thereby improving the sealing effect of the sealing door 18 and preventing it from loosening.

[0042] Working principle: When in use, when the test box body 14 is subjected to left and right forces, the base 1 and the moving frame 3 slide relative to each other, the slide bar 2 slides along the moving frame 3, and the buffer component 4 buffers the force. When the test box body 14 is subjected to front and back forces, the base 1 and the moving frame 2 7 slide relative to each other, the slide bar 2 6 slides along the moving frame 2 7, and the buffer component 2 8 buffers the force. The buffer block 15 and the buffer block 2 9 made of fluororubber have strong weather resistance and cooperate with the buffer component 1 4 and the buffer component 2 8 to improve the shock absorption effect. When the test box body 14 is subjected to up and down forces, the fixed rod 10 slides along the fixed frame 13, the spring 2 12 and the buffer block 3 24 buffer the force. Multiple components cooperate with each other. Improve the shock absorption performance of the test box body 14 and improve the stability of the test box body 14. When the sealing door 18 is closed, the sealing gasket 16 enters the groove 19 and the sealing ring 17 enters the groove 20. The convex edge 21 squeezes the sealing gasket 16 to deform the sealing gasket 16 and fill the groove 19, thereby increasing the length of the seal and improving the sealing effect. After the sealing door 18 is closed, turn the handle 2302 to insert the locking piece 2303 into the slot 2202 and contact the bottom end of the slot 2202. Turn the screw 2203 to insert the screw 2203 into the locking groove 2304 to lock the locking piece 2303. At the same time, apply pressure to the locking piece 2303 to improve the sealing effect of the sealing door 18 and prevent it from loosening.
