A threaded groove 4 is provided on the movable block 3, and the threaded groove 4 is threadedly connected to the lead screw 2. A box 5 is fixedly installed on the outer circumference of the lead screw 2. The lead screw 2 and the movable block 3 are both located inside the box 5. One side of the box 5 is open, and the open side of the box 5 is fixedly installed on the wall 100. A motor 6 is fixedly installed inside the box 5. The output shaft of the motor 6 is coaxial with and fixedly connected to the lead screw 2. A strip-shaped through-slot 7 is provided on the box 5. A first slider 8 is slidably installed in the strip-shaped through-slot 7. The first slider 8 can move back and forth and slide left and right within the strip-shaped through-slot 7. A fixing block 10 is provided below the airtight door 100. The fixing block 10 is fixedly installed on the wall 100. The airtight door 1 is slidably connected to the fixing block 10. A first sliding groove 9 is opened on the airtight door 1 corresponding to the first slider 8. The first slider 8 can only move left and right along the first sliding groove 9. A threaded through groove 11 is opened on one side of the wall 100. A threaded rod 12 is installed in the threaded through groove 11. The two ends of the threaded rod 12 are located on both sides of the wall 100. A movable plate 13 is rotatably installed at one end of the threaded rod 12. The movable plate 13 can only move left and right with the threaded rod 12. A sliding rod 14 is fixedly installed on one side of the movable plate 13. A through hole 15 is opened on the wall 100 corresponding to the sliding rod 14. The sliding rod 14 is slidably installed in the through hole 15. The sliding rod 14 can limit the movable plate 13 and prevent the movable plate 13 from rotating with the threaded rod 12. A movable block 3 is located on one side of the lead screw 2. The movable block 3 is slidably connected to the movable plate 13. The movable block 3 can only move back and forth along the movable plate 13 and cannot move left and right relative to the movable plate 13. This utility model has a simple structure and ingenious design. It can be opened electrically or manually during a power outage, ensuring that people inside the door can open the airtight door 1 to escape in the event of a power outage, reducing the possibility of casualties. It is easy to operate, meets practical needs, and is suitable for widespread application.Using this invention, under normal circumstances, when the door needs to be opened, the control motor 6 works, the motor 6 drives the lead screw 2 to rotate, the lead screw 2 drives the moving block 3 and the first slider 8 to move, the moving block 3 moves along the moving plate 13, and the first slider 8 drives the airtight door 1 to move through the first sliding groove 9, thus opening the airtight door 1. When there is a power outage, the threaded rod 12 is rotated, the threaded rod 12 drives the moving plate 13 to move to the left, the moving plate 13 drives the moving block 3 to move to the left, and the threaded groove 4 on the moving block 3 separates from the lead screw 2. At this time, the lead screw 2 cannot limit the moving block 3. At this time, the airtight door 1 can be opened by pulling it directly. The personnel inside the airtight door 1 can enter and exit through the through groove 16. In case of danger, the personnel inside the airtight door 1 can escape, reducing the possibility of casualties. After the power is restored, the lead screw 2 is rotated in the opposite direction, so that the lead screw 2 drives the moving block 3 to reset.

[0017] Specifically, as shown in the figure, the movable plate 13 in this embodiment has a T-shaped groove 20, and a T-shaped slider 21 is slidably installed in the T-shaped groove 20. The T-shaped slider 21 can only slide back and forth in the T-shaped groove 20. When the movable block 3 moves along the lead screw 2, the T-shaped slider 21 slides in the T-shaped groove 20, limiting the movable block 3 and preventing it from moving up and down. It also ensures that the threaded groove 3 on the movable block 3 always remains engaged with the lead screw 2. At the same time, when it is necessary for the movable block 3 to separate from the lead screw 2, the threaded rod 12 is rotated. The threaded rod 12 drives the movable plate 13 to move. The movable plate 13, through the cooperation of the T-shaped groove 20 and the T-shaped slider 21, drives the movable block 3 to move, so that the movable block 3 separates from the lead screw 2.

[0018] Specifically, as shown in the figure, a rotating shaft 30 is provided in the middle of one side of the wall 100 in this embodiment. Coaxial sprockets 31 are fixedly installed on both the rotating shaft 30 and the threaded rod 12. The two sprockets 31 are connected by a chain 32. Shaft seats 33 are rotatably installed on the outer periphery of the rotating shaft 30 and the threaded rod 12, respectively. The outer periphery of the rotating shaft 30 and the threaded rod 12 are rotatably connected to the inner hole of the shaft seat through bearings. The two shaft seats 33 are fixedly connected. The outer periphery of the two shaft seats 33 is sequentially fixedly connected to both ends of the same vertical rod. A fixing plate 34 is fixedly provided on the bottom side of the rotating shaft 30. The fixing plate 34 is fixedly installed on the wall 100. A second sliding groove 35 is opened on the fixing plate 34. A second slider 36 is slidably installed in the second sliding groove 35. The second slider 36 can only slide left and right in the second sliding groove 35. The second slider 36 is fixedly installed on the shaft seat 33 on the rotating shaft 30. A coaxial handwheel 37 is fixedly installed at one end of the rotating shaft 30. When it is necessary to rotate the threaded rod 12, the rotating shaft 30 is rotated by the handwheel 37. The rotating shaft 30 drives the threaded rod 12 to rotate through the sprocket 31 and the chain 32. The threaded rod 12 moves along the threaded through groove 11. At the same time, the threaded rod 12 drives the rotating shaft 30 to move through the bearing seat 33. The bearing seat 33 on the rotating shaft 30 drives the second slider 36 to slide along the second slide groove 35. At this time, the positions of the sprocket 31 and the chain 32 remain unchanged, ensuring that the rotating shaft 30 and the threaded rod 12 are connected by transmission through the sprocket 31 and the chain 32.

[0019] Furthermore, as shown in the figure, in this embodiment, the wall 100 has a rectangular groove 40 on the outer ring of the through groove 16. Several electric telescopic rods 41 are fixedly installed in the rectangular groove 40. The fixed ends of the electric telescopic rods 41 are fixedly installed in the rectangular groove 40, and the movable ends of the several electric telescopic rods 41 are fixedly installed with the same rectangular rubber pad 42. The rectangular rubber pad 42 can move into the rectangular groove 40. When the airtight door 1 closes the through groove 16, the electric telescopic rods 41 are controlled to extend, and the several electric telescopic rods 41 drive the rectangular rubber pad 42 to move until the rectangular rubber pad 42 is in close contact with the airtight door 2, thereby improving the sealing effect of the airtight door 1.

[0020] Furthermore, as shown in the figure, in this embodiment, a support wheel 50 is rotatably mounted on the lower side of the airtight door 1. A third sliding groove 51 is formed on the fixing block 10 corresponding to the support wheel 50. The support wheel 50 slides in contact with the third sliding groove 51, and the support wheel 50 can only move back and forth in the third sliding groove 51. The support wheel 50 changes the sliding contact between the airtight door 1 and the fixing block 10 to a rolling contact, which can reduce the wear of the airtight door 1.

[0021] Furthermore, as shown in the figure, a groove 60 is formed on one side of the airtight door 1 in this embodiment. A support shaft 61 is fixedly installed in the groove 60, and a bushing 62 is rotatably installed on the outside of the support shaft 61. The outer circumference of the support shaft 61 is rotatably connected to the inner circumference of the bushing 62 through a bearing. A U-shaped rod 63 is fixedly installed on the bushing 62, and the U-shaped rod 63 can be completely located within the groove 60. When it is necessary to manually open the airtight door 1, rotating the U-shaped rod 63 and pulling the airtight door 1 by the U-shaped rod 63 makes it more convenient and less strenuous.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
