[0041] Among them, a door opening 2 is opened on the outer side of the wall 3, and a door cavity 1 is opened on the inner side of the wall 3, the door opening 2 is connected to the door cavity 1, and the height of the door cavity 1 is greater than the height of the door opening 2, and the width of the door cavity 1 is greater than twice the width of the door opening 2. The concrete door body 4 is slidably installed on the inner side of the door cavity 1, the width of the concrete door body 4 is slightly greater than the width of the door opening 2, and the height of the concrete door body 4 is greater than the height of the door opening 2. The concrete door body 4 slides inside the door cavity 1, and it is necessary to ensure that when the concrete door body 4 is in a certain position (the closed position of the concrete door body 4), the concrete door body 4 can completely block the door opening 2, and it is also necessary to ensure that when the concrete door body 4 is in a certain position (the fully opened position of the concrete door body 4), the door opening 2 is completely exposed.
[0042] The driving structure is installed on the inner side of the door cavity 1, and is used to drive the concrete door body 4 to slide on the inner side of the door cavity 1, so as to control the opening / closing of the concrete door body 4. The first extrusion member 8 is located on the inner side of the door cavity 1, and the first extrusion member 8 corresponds to the left side of the door opening 2. The left side of the concrete door body 4 is provided with a first extrusion inclined surface 401, and the side of the first extrusion member 8 is provided with a first inclined surface matching the first extrusion inclined surface 401. The second extrusion member 9 is located on the inner side of the door cavity 1, and the second extrusion member 9 corresponds to the right side of the door opening 2. The right side of the concrete door body 4 is provided with a second extrusion inclined surface The second extrusion member 9 has a second inclined surface 402, and the side surface of the second extrusion member 9 is provided with a second inclined surface matching the second extrusion inclined surface 402. The connecting ear seat 10 is fixedly connected to the concrete door body 4 and is located above the middle part of the door opening 2. The middle part of the first connecting rod 11 is movably connected to the connecting ear seat 10, the first end of the first connecting rod 11 is movably connected to the first extrusion member 8, and the second end of the first connecting rod 11 is movably mounted with a wheel body 13. The first end of the second connecting rod 12 is movably connected to the second extrusion member 9, and the second end of the second connecting rod 12 is movably connected to the connecting ear seat 10, and the wheel body 13 is located on the outside of the second connecting rod 12.
[0043] Working principle: The driving structure drives the concrete door body 4 to slide inside the door cavity 1 (the pre-position is as follows Figure 4 As shown, the first extrusion piece 8 is close to the inner side of the door cavity 1, and the second extrusion piece 9 is far away from the inner side of the door cavity 1, and the concrete door body 4 can slide between the second extrusion piece 9 and the door cavity 1). When the first extrusion slope 401 of the concrete door body 4 contacts the first slope of the first extrusion piece 8, the concrete door body 4 continues to be pushed. At this time, the first extrusion slope 401 of the concrete door body 4 pushes the first slope of the first extrusion piece 8, so that the first extrusion piece 8 moves outward, and the first connecting rod 11 rotates around the connecting ear seat 10, and the wheel body 13 squeezes the second connecting rod 12 inward, and the second connecting rod 12 pushes the second extrusion piece 9 inward. The force of the second extrusion piece 9 squeezing the concrete door body 4 inward is getting stronger and stronger, and the force of the first extrusion slope 401 pushing the first extrusion piece 8 outward is also getting stronger and stronger (conversely, the force of the first extrusion piece 8 on the concrete door body 4 increases), so that the concrete door body 4 can be tightly attached to the door cavity 1 to achieve better sealing.
[0044] The self-falling locking pin structure is installed on the concrete door body 4. When the second extrusion member 9 is extruded toward the concrete door body 4, the locking pin 15 of the self-falling locking pin structure falls behind the second extrusion member 9. After that, the second extrusion member 9 cannot move backward, thereby locking the concrete door body 4.

[0048] The user rotates the threaded seat assembly 6 through the hand wheel, and the threaded seat assembly 6 and the threaded rod 5 rotate relative to each other, so that the threaded rod 5 moves laterally, pushing or pulling the concrete door body 4 to open / close.
[0049] In one embodiment, it also includes: a guide rod 7, one end of which is fixedly connected to the concrete door body 4, the guide rod 7 is slidably connected to the wall 3, the guide rod 7 is used to guide the movement of the concrete door body 4, and the guide rod 7 is arranged parallel to the threaded rod 5.

The locking pin 15 is located on the inner side of the sliding hole of the kit 14, and the top of the locking pin 15 is fixedly connected with a limiting portion 1501. The limiting portion 1501 is arranged horizontally so that the locking pin 15 will not separate from the kit 14. The bottom end of the locking pin 15 is provided with a guiding portion 1502 so that the locking pin 15 can fall smoothly (the guiding portion 1502 is an inclined surface so as to prevent the locking pin 15 from falling suddenly).
[0052] In one embodiment, the second connecting rod 12 is L-shaped, so that the connecting ear seat 10 does not need to be too long, making the structure more compact.
