Description

Technical Field

[0001] This utility model relates to the field of civil defense door technology, specifically a civil defense door accessory storage bracket. Background Technology

[0002] Civil defense doors, also known as fire doors, are facilities installed within fire compartments to prevent the spread of fire, block the diffusion of smoke, and ensure the safe escape of personnel and the protection of property. Their functions include fire prevention, smoke prevention, and prevention of gas diffusion.

[0003] The prior art discloses patent application number "CN201821006911.5", which is a storage bracket for civil defense door accessories. It includes a base with a U-shaped arrangement, a support frame and a fastening limiting mechanism. The support frame is located in the middle of the upper part of the base and is used to separate and support civil defense door accessories. The fastening limiting mechanism is located on the upper part of the support frame and slides vertically along the height direction of the support frame, so that a storage limiting area is formed between the base and the fastening limiting mechanism.

An L-shaped plate 6 is fixedly connected to the upper side of the storage bracket body 1. A threaded rotating rod 7 is rotatably connected between the storage bracket body 1 and the L-shaped plate 6.

[0027] The outer surface of the threaded rotating rod 7 is threadedly connected to a lifting plate 8. U-shaped stop seats 9 are fixedly installed on the lower side of both lifting plates 8. The internal rotatable connection of the storage bracket body 1 is a double-ended screw rod 13. The outer surface of the double-ended screw rod 13 is threadedly connected to two symmetrically distributed L-shaped clamping plates 14. Rubber strips 15 are arrayed on one side of each of the two L-shaped clamping plates 14. Two screw rods 10 are threadedly connected on one side of each of the two U-shaped stop seats 9. Clamping blocks 11 for fixing the main body 4 of the air defense door are fixedly connected on one side of each of the two screw rods 10.

[0028] Four self-locking casters 5 are fixedly connected to the lower side of the storage bracket body 1 for moving the storage bracket body 1. The self-locking casters 5 can be used to move the storage bracket to the installation position for assembling the air defense door accessories. The second U-shaped stop 9 is located directly above the first U-shaped stop 2. The L-shaped clamp 14 is located inside the first U-shaped stop 2. One side of the screw 10 passes through the second U-shaped stop 9 and extends into the interior of the second U-shaped stop 9. Rubber pads 12 are fixedly connected to one side of each of the two clamps 11. Through the installation and use of the rubber pads 12 and rubber strips 15, the friction with the air defense door can be increased by using the rubber pads 12 on the clamps 11 and the rubber strips 15 on the L-shaped clamps 14, so as to stably and reliably fix the air defense door in the two sets of U-shaped stops.

[0029] A square base 23 is fixedly provided on the upper side of the main body 1 of the storage bracket. An extension frame 24 is snapped into the inside of the square base 23. An accessory storage box 25 is fixedly connected to the upper side of the extension frame 24. An array of L-shaped sliding plates 29 are slidably snapped into both ends of the accessory storage box 25.

The upper side of the rotating shaft 26 passes through the accessory storage box 25 and extends to the upper side of the accessory storage box 25. A second operating handwheel 28 is fixedly provided on the upper side of the rotating shaft 26. Two symmetrically distributed U-shaped handles 88 are fixedly connected to the upper side of the accessory storage box 25.

[0031] Four reinforcing columns 20 are fixedly connected to the upper side of the main body 1 of the storage bracket. Each of the four reinforcing columns 20 has a lifting ring 21 threaded on its upper side. The entire storage bracket can be lifted by the lifting ring 21, allowing it to be moved to the transportation position so that the storage bracket can be transported stably and safely for the personnel door accessories. A support rod 22 is fixedly installed between two reinforcing columns 20.

[0032] The storage bracket body 1 is internally fixedly connected to a first limiting rod 16. The interior of two L-shaped clamping plates 14 is slidably connected to the outer surface of the first limiting rod 16. The first limiting rod 16 can guide and limit the movement trajectory of the two L-shaped clamping plates 14, allowing the two L-shaped clamping plates 14 to stably clamp the air defense door. A first operating handwheel 17 is fixedly installed on one side of the storage bracket body 1. One side of the first limiting rod 16 is fastened to the first operating handwheel 17. A second limiting rod 19 is fixedly connected between the L-shaped plate 6 and the threaded rotating rod 7. The interior of the lifting plate 8 is slidably connected to the outer surface of the second limiting rod 19. The second limiting rod 19 can guide the up and down movement of the lifting plate 8, allowing the two U-shaped stops 9 to move up and down smoothly for clamping air defense doors of different sizes. A servo motor 18 is fixedly installed on the upper side of the L-shaped plate 6. The output shaft of the servo motor 18 is fastened to the threaded rotating rod 7.

[0033] The working principle of the air defense door accessory storage bracket provided by this utility model is as follows:

[0034] By placing the main body 4 of the air-raid shelter door onto the rollers 3 inside the U-shaped stop 2, the air-raid shelter door can be moved by rolling, allowing it to be easily moved to the clamping position. Then, the output shaft of the servo motor 18 drives the threaded rotating rod 7 to rotate, so that the lifting plate 8 on the threaded rotating rod 7 can move downward, allowing the two U-shaped stop 9s at the lifting plate 8 to move and position themselves above the air-raid shelter door. Next, the screw 10 is rotated in sequence, which drives the clamping block 11 to move, allowing the clamping block 11 to move. The upper position of one side of the air-raid shelter door is clamped and positioned. Then, the first operating handwheel 17 is turned to drive the double-ended screw 13 to rotate, so that the two L-shaped clamps 14 on the double-ended screw 13 move towards each other, so that the two L-shaped clamps 14 can clamp to the lower position of one side of the air-raid shelter door. In this way, the U-shaped stop, clamp 11 and L-shaped clamp 14 can clamp air-raid shelter doors of different sizes without the need to replace the matching storage bracket, thus expanding the application range of the storage bracket and improving the applicability of the air-raid shelter door accessory storage bracket.

[0035] By sequentially pulling out the insert rod 32 and rotating the four limiting plates 31 away from the riser 24, and then holding the two U-shaped handles 88, the accessory storage box 25 on the riser 24 can be moved out from inside the square base 23, so that the accessory storage box 25 on the air defense door accessory storage bracket can be flexibly and conveniently removed for the installation of air defense door accessories. Then, turn the second operating handwheel 28 to drive the double-headed convex plate 27 on the rotating shaft 26 to rotate. In this way, the double-headed convex plate 27 can squeeze multiple air defense door accessory boxes 30 and move the air defense door accessory boxes 30, so that all the air defense door accessory boxes 30 are in the open state, so as to quickly find the required air defense door accessories, saving time and effort.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
