[0002] A computer room is a place with relatively strict environmental requirements, which is used to centrally place various electronic devices to achieve specific functions. The computer room can also be used for the testing of electronic devices. Some electronic devices may be used in high-altitude or special air pressure environments. In this case, when testing, by increasing the internal pressure of the computer room, the working state of the device under different air pressure conditions can be simulated, and the performance, sealing performance of the device in these environments and whether there will be failures caused by air pressure changes can be detected in advance. When testing, a pressure relief device also needs to be set on the computer room.

[0054] Among them, in order to achieve the purpose of orderly operation, the present device is implemented by the following technical solutions: One side of the push plate 19 is fixedly connected with a first magnetic ring 24, and one side inner wall of the housing 12 is fixedly connected with a second magnetic ring 25. Both the first magnetic ring 24 and the second magnetic ring 25 are sleeved outside the U-shaped rod 23. There are four stabilizing components evenly distributed in a circumferential shape outside the housing 12. The stabilizing component includes a U-shaped frame 26. The U-shaped frame 26 is fixedly connected to the top of the housing 12. One side of the U-shaped frame 26 is fixedly connected with a support plate 27. One side of the support plate 27 is fixedly connected with a plug 28. Two support rods 29 are fixedly connected to the inner wall of the top of the cylinder 5. Two connecting rods 30 are fixedly connected between the two support rods 29. Rotating frames 31 are sleeved on both of the two connecting rods 30. Rollers 32 are connected to both of the two rotating frames 31. Both of the two rollers 32 are in sliding contact with the plug 28. Torsion springs 33 are sleeved outside both of the two connecting rods 30, and the inner ends of the two torsion springs 33 are respectively fixedly connected to the front and rear sides of the rotating frame 31, and the outer ends of the two torsion springs 33 are respectively fixedly connected to the inner sides of the two support rods 29. Two stop rods 34 are also fixedly connected between the two support rods 29. The two stop rods 34 are respectively in contact with the inner sides of the two rotating frames 31. The rotating frame 31 and the connecting rod 30 are connected by bearings. The designs of the first magnetic ring 24, the second magnetic ring 25 and the stabilizing components can achieve that when the pressure is relieved, the air in the air cushion 10 is sucked back first, and then the sealing plug 9 is separated from the sealing seat 8. When sealing, the sealing plug 9 contacts the sealing seat 8 first and then the air cushion 10 is inflated.

[0055] The usage process of the present invention is as follows: Install the door frame 1 on the wall of the computer room. Then, press the knob 43 to move the second rotating shaft 42, the ring 50, and the two first inserting rods 51 towards the direction close to the third gear 48. In this way, the two first inserting rods 51 can be inserted into the two through holes 52 on the third gear 48, and at the same time, the two second inserting rods 54 in the two through holes 52 are pushed out, and the two springs 55 close to the third gear 48 are compressed. When the ring 50 contacts the third gear 48, the right end of the first inserting rod 51 is flush with the right side of the third gear 48, and exactly the two second inserting rods 54 completely move out of the through holes 52 on the third gear 48. Then, rotate the knob 43 half a turn. The rotation of the knob 43 can make the second rotating shaft 42, the ring 50, and the two first inserting rods 51 rotate. The rotation of the two first inserting rods 51 drives the third gear 48 to rotate. The rotation of the third gear 48 drives the fourth gear 49 to rotate. The rotation of the fourth gear 49 drives the first rotating shaft 35 and the turntable 36 to rotate. Since the pull rods 40 can move between the first convex rod 38 and the second convex rod 39 through bearings, under the action of the two pull rods 40, the rotation of the turntable 36 can make the two locking rods 37 move towards the middle. Then, push the door body 2 to close the door body 2. At the same time, the sealing ring 7 on the door body 2 fits together with the return-shaped frame 6. Then, rotate the knob 43 half a turn in the reverse direction, so that the turntable 36 can be reversed, and then the two locking rods 37 can be pushed to move outwards. Then, the ends of the two locking rods 37 can be stuck in the two locking grooves 3. The ends of the locking rods 37 have inclined openings, and the edges of the locking grooves 3 are arc-shaped. When the ends of the locking rods 37 move into the locking grooves 3, the inclined openings of the locking rods 37 will contact the edges of the locking grooves 3. When the inclined opening parts completely move into the locking grooves 3, the door body 2 can be moved closer to the return-shaped frame 6 for a certain distance. In this way, the sealing ring 7 on the door body 2 can be in close contact with the return-shaped frame 6 on the door frame 1. In this way, it is possible to avoid gaps between the door body 2 and the door frame 1, and further avoid external dust and cold air from entering the computer room, so as to achieve the effect of heat preservation and dust prevention;

[0056] After the door body 2 is closed, pull back the knob 43, so that the second rotating shaft 42, the ring 50, and the two first inserting rods 51 can be reset. At the same time, the two springs 55 close to the third gear 48 will rebound, so that the two second inserting rods 54 close to the third gear 48 can be inserted into the two through holes 52 on the third gear 48 again. In this way, it is possible to avoid the random rotation of the third gear 48, and further avoid the random rotation of components such as the fourth gear 49, the first rotating shaft 35, and the turntable 36, so as to avoid the random removal of the locking rods 37 from the locking grooves 3;

[0057] After the door body 2 is closed, the inside of the machine room can be pressurized to test the electronic equipment. After the test is completed, pressure relief can be carried out. When relieving the pressure, pull the knob 43 to move the second rotating shaft 42, the ring 50 and the first inserting rod 51 towards the direction close to the second gear 47. In this way, the two first inserting rods 51 can be inserted into the two through holes 52 on the second gear 47, and at the same time, the two second inserting rods 54 in the two through holes 52 are pushed out, and the two springs 55 close to the second gear 47 are compressed. When the ring 50 contacts the second gear 47, the left end of the first inserting rod 51 is flush with the left side of the second gear 47, and just the two second inserting rods 54 completely move out of the through holes 52 on the second gear 47. Then rotate the knob 43 to rotate the second rotating shaft 42, the ring 50 and the two first inserting rods 51. In this way, the rotation of the two first inserting rods 51 can make the two second gears 47 rotate. The rotation of the two second gears 47 drives the first gear 46 to rotate. The rotation of the first gear 46 drives the third rotating shaft 45 to rotate. The rotation of the third rotating shaft 45 drives the threaded rod 21 to rotate. The rotation of the threaded rod 21 drives the threaded block 22 and the U-shaped rod 23 to move to the left. Then under the action of the four stabilizing components, the leftward movement of the U-shaped rod 23 can make the push plate 19 move to the left first. In this way, the four moving rods 18 and the four pistons 16 can move to the left first. Then under the action of the four second pipelines 17, the air in the air cushion 10 can be sucked back into the four boxes 15 first. When the push plate 19 moves to the left, the first magnetic ring 24 also moves to the right. When the first magnetic ring 24 is attracted to the second magnetic ring 25, the air in the air cushion 10 is completely sucked back. In this way, the air cushion 10 will not contact the sealing seat 8. Then rotate the knob 43 to make the threaded rod 21 continue to rotate, so that the U-shaped rod 23 and the push plate 19 continue to move to the left. At this time, the push plate 19 can pull the housing 12, the connecting block 11 and the sealing plug 9 to move to the left. In this way, the sealing plug 9 will not contact the sealing seat 8. Then the air can be discharged through the first pipeline 14. In this way, pressure relief can be achieved;

[0058] When the housing 12 moves to the left, it can also make the U-shaped frame 26, the support plate 27 and the inserting block 28 move to the left. Since the left and right sides of the inserting block 28 are both sharp, and the two rollers 32 are in sliding contact with the inserting block 28. In this way, under the action of the two rollers 32, during the leftward movement of the inserting block 28, the two rotating frames 31 can rotate respectively around the two connecting rods 30 as the rotation axes. In this way, the angle between the two rotating frames 31 becomes larger, and at the same time, the torsion spring 33 is compressed more severely. In this way, the inserting block 28 can smoothly move out between the two rollers 32;

[0059] After the pressure relief is completed, reverse the knob 43 to move the threaded block 22 to the right, so that the U-shaped rod 23 and the push plate 19 can be moved to the right. Since the second magnetic ring 25 is attracted to the first magnetic ring 24, the push plate 19, the housing 12, the connecting block 11 and the sealing plug 9 can be moved to the right at the same time. At the same time, the U-shaped frame 26, the support plate 27 and the insertion block 28 will also move to the right. When the sealing plug 9 contacts and fits with the sealing seat 8, the insertion block 28 will pass through between the two rollers 32. The suction force between the first magnetic ring 24 and the second magnetic ring 25 is much greater than the resistance of the two rollers 32 to open. In this way, the insertion block 28 can smoothly pass through between the two rollers 32 during the rightward movement. When the sealing plug 9 contacts and fits with the sealing seat 8, a primary seal can be achieved. Then continue to reverse the knob 43 to move the threaded block 22 further to the right. At this time, the housing 12, the connecting block 11 and the sealing plug 9 cannot move to the right anymore. At this time, the U-shaped rod 23 can push the push plate 19, the four moving rods 18 and the four pistons 16 to the right. In this way, the air in the four boxes 15 can enter the air cushion 10, so that the air cushion 10 is inflated and bulged, and then contacts the inner wall of the sealing seat 8 to achieve a secondary seal. In this way, the sealing effect can be increased, so that there will be no air leakage when increasing the internal pressure of the computer room, and then the internal pressure of the computer room can reach the test standard in a short time;

[0060] When the sealing plug 9 contacts and fits with the sealing seat 8 and the air cushion 10 contacts the sealing seat 8, push the knob 43 back to reset the second rotating shaft 42, the ring 50 and the two first inserting rods 51. At the same time, the two springs 55 close to the second gear 47 will rebound, so that the two second inserting rods 54 close to the second gear 47 can be inserted into the two through holes 52 on the second gear 47 again. In this way, the second gear 47 can be prevented from rotating randomly, and further the first gear 46, the third rotating shaft 45, the threaded rod 21 and other components can be prevented from rotating randomly. In this way, the separation of the sealing plug 9 from the sealing seat 8 and the air in the air cushion 10 returning to the box 15 can be avoided, and the sealing effect can be maintained all the time;

[0061] Before pressing and pulling the knob 43, the knob 43 can be rotated first to align the indicating rod 56 on the second rotating shaft 42 with the indicating board, so that the first inserting rod 51 can be smoothly inserted into the through hole 52 when pressing and pulling the knob 43.

[0062] The above is only a preferred embodiment of the present invention. Any person skilled in the art may modify the present invention by using the technical solutions described above or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solutions of the present invention shall fall within the scope of protection of the present invention.
