[0027] When the crank handle 7 is turned clockwise, the crank handle 7 drives the take-up wheel 6 to take up the traction chain 8 on the outer peripheral wall of the take-up wheel 6, so that the length of the traction chain 8 shrinks along the outer peripheral wall of the movable pulley 5 toward the take-up wheel 6. Conversely, the take-up wheel 6 pays off the traction chain 8 taken up by its outer peripheral wall, thereby increasing the length of the traction chain 8 that is out of the take-up wheel 6.

[0028] See also Figure 3-4 As shown in the figure, the structure that causes the two limit plates 3 to move toward each other includes a rotating rod 10 that passes through and is rotatably installed between the two limit plates 3. A locking pin component (not shown in the figure) is installed on the rotating rod 10. The locking pin component is a series of pin holes arranged along the axial or circumferential direction on the rotating rod 10, and a locking pin that can be inserted into the pin hole corresponds to the locking pin. When the rotating rod 10 is rotated to a position that needs to be locked, the locking pin is inserted into the pin hole of the rotating rod 10 and the surrounding connecting structure (base 1), so that the rotating rod 10 is fixed so that it cannot rotate. The rotating rod 10 extends to the bottom A gear 11 is fixedly installed at one end of the inner side of the seat 1, and an upper rack 12 and a lower rack 13 are fixedly installed on the side of the two limit plates 3 adjacent to the gear 11, respectively. The upper rack 12 and the lower rack 13 are respectively meshed with the top and the bottom of the outer peripheral wall of the gear 11, and rubber pads are fixedly installed on the opposite sides of the two limit plates 3. When the rotating rod 10 is rotated in the clockwise direction, the rotating rod 10 will cause the upper rack 12 and the lower rack 13 to drive the two limit plates 3 closer to each other through the gear 11, and vice versa, the two limit plates 3 are moved away from each other;

[0029] See also Figure 2-4As shown, a slider 14 is slidably installed on the top of the base 1, a screw 15 is threadedly connected to the bottom of the slider 14, and both ends of the screw 15 are rotatably connected to the two sides of the base 1, a slide plate 16 is fixedly installed on the top of the slider 14, and a positioning plate 17 is fixedly installed on the top of the slide plate 16. The positioning plate 17 is provided with a plurality of positioning holes 18 distributed at equal distances, and a slide plate 2 19 is slidably installed on the positioning plate 17, and a plurality of rollers distributed at equal distances are rotatably installed at the bottom of the slide plate 2 19, and the bottom of the roller is aligned with the top of the base 1. Fitting, the roller is used to promote the sliding plate 19 to slide on the top of the base 1, the top of the sliding plate 19 is threadedly connected with a positioning rod 20 adapted to the positioning hole 18, the side of the sliding plate 16 adjacent to the limit plate 3 is rotatably installed with a lifting plate 21, and both sides of the sliding plate 19 are rotatably installed with push-pull plates 22, and the end of the push-pull plate 22 away from the sliding plate 19 is rotatably connected to one side of the lifting plate 21, and the side of the lifting plate 21 away from the rotating shaft is fixedly installed with a lifting ring 23, and the top of the lifting plate 21 is installed with a clamping assembly 24 for fixing the door panel;

[0030] When the screw rod 15 is rotated in the clockwise direction, the screw rod 15 will drive the slide plate 16 to move in the direction of the limit plate 3 through the slider 14, and vice versa, the slide plate 16 will be prompted to move in the direction away from the limit plate 3. When the slide plate 2 19 moves along the positioning plate 17 toward the direction of the rotation axis of the lifting plate 21, the slide plate 2 19 will push the lifting plate 21 to rotate in the clockwise direction along the rotation axis through the push-pull plate 22. By moving the positioning rod 20 on the slide plate 2 19 to a position aligned with the positioning hole 18, and then rotating the positioning rod 20 in the clockwise direction to make it move vertically downward, the bottom end of the positioning rod 20 is inserted into the positioning hole 18 to limit the slide plate 2 19, thereby fixing the rotation state of the lifting plate 21.

[0031] See also Figure 1-4 As shown, the clamping assembly 24 includes a support plate 241 slidably mounted on the top of the lifting plate 21, an electric push rod driving the support plate 241 to slide is mounted on the slide plate 16, a mounting frame 242 is fixedly mounted on the top of the support plate 241, a clamping plate 243 is slidably mounted on the mounting frame 242, a screw rod 244 is threadedly connected to the top of the mounting frame 242, one end of the screw rod 244 is rotatably connected to the top of the clamping plate 243, and the side of the clamping plate 243 away from the screw rod 244 is made of rubber material;

[0032] By rotating the second screw rod 244 in the clockwise direction, the second screw rod 244 will drive the clamping plate 243 to move toward the support plate 241, thereby reducing the distance between the support plate 241 and the clamping plate 243, and vice versa, the distance between the support plate 241 and the clamping plate 243 is increased.

[0033] When the present invention is in use, the civil defense door to be installed is first placed between the support plate 241 and the clamping plate 243, and then the clamping plate 243 is moved toward the support plate 241 until it clamps the civil defense door between the support plate 241 and it, and then the length of the traction chain 8 that is separated from the winding wheel 6 is increased, and then the hook 9 is pulled to the position of the hanging ring 23 and inserted into the hanging ring 23, and then the winding wheel 6 is rotated counterclockwise, so that the traction chain 8 that is separated from the winding wheel 6 is wound toward the outer peripheral wall of the winding wheel 6, and then the traction chain 8 is pulled by the hook 9 to rotate the lifting plate 21 along the rotating axis in the clockwise direction. At the same time, the lifting plate 21 will pull the sliding plate 21 through the push-pull plate 22 to move along the positioning plate 17 toward the rotating axis of the lifting plate 21. Until the lifting plate 21 is rotated to a position perpendicular to the ground, the positioning rod is rotated clockwise. 20, so as to limit the positioning rod 20 in the positioning hole 18, thereby limiting the state of the lifting plate 21 after rotation, and then increase the length of the traction chain 8 that is separated from the winding wheel 6, and then take the hook 9 out of the lifting ring 23, and then make the base 1 move the two limiting plates 3 into the door opening through the universal wheel 2, and align the civil air defense door fixed on the top of the base 1 with the door opening, and then make the two limiting plates 3 move away from each other until the two limiting plates 3 are respectively abutted against the inner walls on both sides of the door opening, and the position relationship between the base 1 and the door opening is fixed, and then make the support plate 241 move along the vertical direction of the lifting plate 21 until the hinged leaf on one side of the civil air defense door is aligned with the hinged leaf on the door opening wall in the vertical direction, and then make the slide plate 16 drive the civil air defense door to move in the direction of the door opening, so that the hinged leaf on the civil air defense door is accurately positioned at the hinged leaf on the door opening wall, so as to facilitate the subsequent installation by the construction personnel;

[0034] When the civil defense door is installed, the distance between the two limit plates 3 is reduced, the restriction between the base 1 and the door opening is released, and then the clamping plate 243 is released from the clamping of the civil defense door. The base 1 is moved to cause the civil defense door to be pulled out from the penetration position between the clamping plate 243 and the support plate 241, so that the civil defense door can be detached from the clamping assembly 24.
