Description

Technical Field

[0001] The utility model belongs to the technical field of reinforcement accessories, in particular to a novel reinforcement accessory for a civil air defense door. Background Art

[0002] Civil defense doors are the doors at the entrances and exits of people's defense projects. There are distinct classifications of civil defense doors, including ordinary single-leaf and double-leaf protective closed doors and closed doors, movable threshold single-leaf and double-leaf protective closed doors and closed doors, and other civil defense equipment.

[0003] When in use, most existing civil air defense doors are locked only by mechanical locks or by locking pins engaged with locking pin grooves. This is the only reinforcement, which results in poor overall impact resistance of the civil air defense door, and ultimately poor safety performance of the civil air defense door. Utility Model Content

[0004] The technical problem that the utility model aims to solve is that the overall anti-collision performance of the existing civil air defense doors is relatively poor, which ultimately leads to the poor safety performance of the civil air defense doors.

[0005] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: a new type of civil defense door reinforcement accessory, including a civil defense door body, a reinforcement frame and a support plate, the reinforcement frame is arranged on the side wall of the civil defense door plate body, the top of the support plate is slidably arranged on the reinforcement frame, the bottom of the reinforcement frame is rotatably hinged with a support arm, the end of the support arm is rotatably connected to the support plate through an axis, and telescopic parts are provided on the top of the reinforcement frame and the support plate.

[0006] Preferably, the support plates are provided in multiple groups, and connecting plates are provided between the support plates.

[0007] Preferably, the telescopic member comprises an electric telescopic rod, a fixed end of the electric telescopic rod is arranged on the top of the reinforcement frame, and a movable end of the electric telescopic rod is arranged on the connecting plate.

[0008] Preferably, a steel mesh is provided inside the reinforcement frame, a pad is provided at the edge of the reinforcement frame, and the pad is connected to the civil defense door body by bolts.

[0009] Preferably, a support seat is rotatably hinged at the bottom end of the support plate, and a rubber pad is provided at the bottom of the support seat.

[0010] Preferably, the side wall of the civil defense door body is provided with a hinge chain.

[0011] The utility model adopts the above structure to achieve the following beneficial effects: the top of the support plate is driven downward by the telescopic part, and the support arm and the support arm are expanded to form a triangular structure. At the same time, the bottom end of the support plate is pressed against the ground to reinforce the civil defense door body, realizing double reinforcement in addition to the mechanical lock, and triple reinforcement is achieved in conjunction with the steel mesh.

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-4As shown, the utility model proposes a new type of civil defense door reinforcement accessory, including a civil defense door body 1, a reinforcement frame 2 and a support plate 3, the reinforcement frame 2 is arranged on the side wall of the civil defense door plate body, the top of the support plate 3 is slidably arranged on the reinforcement frame 2, the bottom of the reinforcement frame 2 is rotatably hinged with a support arm 4, the end of the support arm 4 is rotatably connected to the support plate 3 by an axis, and the support plates 3 are provided with multiple groups, and connecting plates 6 are provided between the support plates 3. A telescopic member 5 is provided on the top of the reinforcement frame 2 and the support plate 3, and the top of the support plate 3 is driven downward by the telescopic member 5, so that a triangular structure is expanded between the support arm and the support arm 4, and at the same time, the bottom end of the support plate 3 is pressed against the ground to reinforce the civil defense door body 1, thereby realizing double reinforcement in addition to the mechanical lock.

[0020] The telescopic member 5 includes an electric telescopic rod 7, a fixed end of which is disposed on the top of the reinforcement frame 2, and a movable end of which is disposed on the connecting plate 6. The electric telescopic rod 7 can be extended and retracted to drive the support plate 3 to rest against the ground or be retracted.

[0021] A steel mesh 8 is provided inside the reinforcement frame 2, and a pad 9 is provided at the edge of the reinforcement frame 2. The pad 9 is connected to the civil air defense door body 1 by bolts. The steel mesh 8 can be used to perform triple reinforcement on the civil air defense door panel body.

[0022] The bottom end of the support plate 3 is rotatably hinged with a support seat 10 , and a rubber pad 11 is provided at the bottom of the support seat 10 , so as to increase the friction between the support seat 10 and the ground.

[0023] The side wall of the civil air defense door body 1 is provided with a hinge chain 12 for connecting with an external support.

[0024] During specific use, the electric telescopic rod 7 is extended to drive the top of the support plate 3 to move downward, and the support arm and the support arm 4 are expanded to form a triangular structure. At the same time, the support seat 10 and the rubber pad 11 at the bottom of the support plate 3 are pressed against the ground to reinforce the civil defense door body 1. In addition to the double reinforcement of the mechanical lock, the electric telescopic rod 7 is contracted to retract the support plate 3 to facilitate the opening and closing of the civil defense door body 1, and the steel mesh 8 can be used to triple reinforce the civil defense door panel body.
