[0026] A reinforcement and stabilization device for an anti-collision door leaf frame for a civil air defense door, comprising an outer frame 1 and an inner frame 2 arranged on the front side of the outer frame 1, mounting blocks 101 are fixedly installed on the left side of the outer frame 1, a protective door 102 is arranged between the mounting blocks 101, a mounting cavity 103 is provided inside the protective door 102, a bidirectional screw 1031 and a drive shaft 1032 are provided inside the mounting cavity 103, a slave gear 1033 and a clamping block 1034 are sleeved on the outer side of the bidirectional screw 1031, a main gear 1035 is fixedly installed on one end of the drive shaft 1032, a drive wheel 1036 is fixedly provided on the other end of the drive shaft 1032, clamping holes 104 are provided at the top and bottom ends of the inner side of the outer frame 1, and a stabilizing reinforcement mechanism 3 is provided on the outer side of the inner frame 2;

[0027] Specifically, the top and bottom ends of the protective door 102 are movably connected to the mounting block 101 through a rotating shaft, the outer surface of the driving shaft 1032 does not contact the outer surface of the bidirectional screw 1031, and one end thereof movably penetrates the inner wall of the mounting cavity 103 through a bearing and extends to the outside of the protective door 102, the cross-sectional shape of the main gear 1035 and the slave gear 1033 is a conical structure and meshingly connected, the inner wall of the clamping block 1034 is threadedly connected to the outer surface of the bidirectional screw 1031, and the top end thereof fits and penetrates the top inner wall of the mounting cavity 103 and extends outward, and the clamping block 1034 is correspondingly arranged and clamped with the clamping hole 104;

[0028] In this embodiment, under the action of the rotating shaft, the protective door 102 can be easily pushed, and the driving wheel 1036 is mainly used to drive the driving shaft 1032. Under the meshing transmission of the main gear 1035 and the slave gear 1033, the rotation of the bidirectional screw 1031 is realized, causing the block 1034 and the bidirectional screw 1031 to move, thereby making the block 1034 and the card hole 104 separate or close to each other, thereby achieving the effect of opening and closing the protective door 102, which is convenient for users to operate.

[0029] It should be noted that the front surface of the outer frame 1 is welded to the rear surface of the inner frame 2, and the protective door 102 is made of a reinforced steel plate.

[0030] In this embodiment, please refer to Figure 1 and Figure 3 The stabilizing and reinforcing mechanism 3 includes a through hole 301 and an adapting groove 302. The through holes 301 are respectively provided on the inner walls of the left and right sides of the inner frame 2, and a reinforcing screw 303 is provided inside the through holes 301. The adapting groove 302 is provided on the inner top of the inner frame 2, and a driving screw 304 is rotatably provided on the inner wall of the top thereof. A guide plate 305 is sleeved on the outer side of the driving screw 304, and a guide column 306 is fixedly installed on the top surface of the guide plate 305.

[0031] Specifically, the opposite ends of the through hole 301 extend to the left and right side surfaces of the inner frame 2 respectively, the opposite ends of the reinforcing screw 303 are sharp, the inner wall of the guide plate 305 and the outer surface of the driving screw 304 are threaded, and the top of the guide column 306 fits through the top inner wall of the adapting groove 302 and extends to the top of the inner frame 2;

[0032] In this embodiment, the through hole 301 is mainly used for the penetration of the reinforcement screw 303, so that the reinforcement screw 303 can be screwed into the wall, providing a lateral pulling force for the inner frame 2, and the driving screw 304 is mainly used to drive the guide plate 305, so that the guide plate 305 drives the guide column 306 to form a close contact with the wall, providing a vertical supporting force for the inner frame 2, thereby improving the stability between the inner frame 2 and the wall and meeting the reinforcement requirements of the civil defense door.

[0033] The working process of the utility model is as follows: when using a reinforcement and stabilization device for an impact-resistant door leaf frame for a civil air defense door, the civil air defense door is first moved to the desired position, the outer frame 1 and the inner frame 2 are fixed, the outer frame 1 and the inner frame 2 are moved, the inner frame 2 is embedded in the wall, and then the reinforcement screw 303 is passed through the through hole 301 and screwed into the interior of the wall, the head of the device reinforcement screw 303 contacts the inner wall of the inner frame 2, thereby causing the inner frame 2 to be subjected to a lateral pulling force, at this time, the driving screw 304 is rotated, the driving screw 304 drives the guide plate 305 to move, and the guide plate 305 drives the guide column 306 to move upward, so that the guide The column 306 is squeezed against the wall, so that the inner frame 2 is subjected to the squeezing support force from the vertical direction, thereby improving the stability between the outer frame 1, the inner frame 2 and the wall. The protective door 102 is then rotated to make it contact with the outer frame 1, and then an external force is applied to the driving wheel 1036 to drive the main gear 1035 to rotate. Under the meshing transmission of the main gear 1035 and the slave gear 1033, the rotation of the bidirectional screw 1031 is realized, and then the block 1034 gradually contacts the card hole 104 along the inner wall of the protective door 102, thereby completing the closing operation of the protective door 102, which is convenient for the subsequent use of the civil defense door.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
