Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof door bolt technology, specifically relating to an explosion-proof door bolt assembly for a gun and ammunition explosion-proof cabinet. Background Technology

[0002] Gun and ammunition explosion-proof cabinets, also known as gun and ammunition safes or explosion-proof gun cabinets, are specially designed storage devices for the safe storage of firearms, ammunition, explosives, or other dangerous goods. They have functions such as fire prevention, explosion prevention, and theft prevention. When using a gun and ammunition explosion-proof cabinet, the explosion-proof door installed on the surface of the cabinet needs to be reinforced for explosion prevention. This is usually achieved by installing explosion-proof door bolts. The existing explosion-proof door bolts are fasteners used to reinforce the explosion-proof door on the explosion-proof cabinet for explosion prevention, which facilitates the reinforcement and explosion-proof use.

[0003] When existing explosion-proof door bolts are installed on explosion-proof cabinets, they are directly reinforced by snapping the bolts onto the middle of one side of the cabinet. Therefore, the bolts can only reinforce one side of the cabinet door. In addition, the bolts are installed by spring-loaded snapping, and the spring force weakens with frequent snapping, reducing the bolt's stability and resulting in poor explosion-proof performance. This affects the reinforcement of the explosion-proof door bolts installed on the explosion-proof cabinet. To address this issue, this utility model proposes an explosion-proof door bolt assembly for bullet-proof cabinets. Utility Model Content

[0004] The purpose of this utility model is to provide an explosion-proof door bolt assembly for a gun and ammunition explosion-proof cabinet, in order to solve the problems mentioned in the background art, where the explosion-proof door bolt is directly installed in the middle of one side of the explosion-proof cabinet for reinforcement. Therefore, the bolt can only reinforce one side of the explosion-proof cabinet door. In addition, the bolt is installed by spring elastic engagement, and the elastic force of the spring weakens with frequent engagement, reducing the fixation of the bolt installation and resulting in poor explosion-proof performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof door bolt assembly for a gun and ammunition explosion-proof cabinet, comprising an explosion-proof door bolt body, wherein the explosion-proof door bolt body includes a mounting post, and fixing plates are provided at both ends of the mounting post; the explosion-proof door bolt body is further provided with:

[0006] A uniformly stressed reinforcement mechanism, comprising a movable adjustment component disposed at the middle position inside the mounting column, a rotation adjustment component disposed on one side of the movable adjustment component on the surface of the mounting column, and a reinforcement mounting component disposed at the connection between the end of the movable adjustment component and the interior of the fixed plate.

[0007] An anti-rotation reinforcement mechanism is provided, and the anti-rotation reinforcement mechanism includes a locking reinforcement component located in the middle of the movable adjustment component, wherein a screw-in adjustment component is provided at the connection between the end of the locking reinforcement component and the surface of the mounting column.

[0008] Preferably, the movable adjustment assembly includes a bidirectional lead screw that rotates inside the mounting column, and the end of the bidirectional lead screw is provided with a movable column inside the mounting column.

[0009] Preferably, the rotation adjustment assembly includes a rotating rod rotatably connected to the front surface of the mounting column, one end of the rotating rod being fixed with a torsion gear one inside the mounting column, the other end of the rotating rod having an internal hexagonal groove, and a torsion gear two being fixed at the middle position of the bidirectional lead screw.

[0010] Preferably, the surfaces of the first torsion gear and the second torsion gear mesh, and the rotating rod and the bidirectional lead screw are rotatably connected through the first torsion gear and the second torsion gear.

[0011] Preferably, the reinforcement installation assembly includes limiting movement grooves formed inside both ends of the installation column, and a bolt post is fixed inside the limiting movement groove at the end of the moving column. A bolt hole is formed inside the fixing plate, and the end of the bolt post engages with the inside of the bolt hole.

[0012] Preferably, the locking and reinforcing assembly includes an inner tooth engagement plate disposed at the middle position inside the mounting column on the surface of the bidirectional lead screw, the end of the inner tooth engagement plate is fixed with a pull plate, and the inner surface of the inner tooth engagement plate is in contact with the outer surface of the bidirectional lead screw.

[0013] Preferably, the screw-in adjustment assembly includes an adjustment bolt threadedly connected to the middle position of the front surface of the mounting post, and the end of the adjustment bolt is rotatably connected to the middle position of the end of the pull plate via a rotating ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By designing a uniformly stressed reinforcement mechanism, two moving columns can be moved towards each other. When the moving columns move, they drive the bolt column to move inside the limiting moving groove until the bolt column is engaged inside the bolt hole to reinforce the cabinet door. This facilitates the reinforcement and explosion-proof installation, ensuring that both ends of one side of the cabinet door are reinforced and explosion-proof. Long-term use is less prone to instability and the reinforcement remains more stable, improving the reinforcement and explosion-proof effect of the explosion-proof bolt body installed on the explosion-proof cabinet.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: an explosion-proof door bolt assembly for a gun and ammunition explosion-proof cabinet, including an explosion-proof door bolt body 100, the explosion-proof door bolt body 100 including a mounting post 101, both ends of the mounting post 101 are provided with fixing plates 102, and the explosion-proof door bolt body 100 is also provided with:

[0025] The uniform force-bearing reinforcement mechanism includes a movable adjustment component located at the middle position inside the mounting column 101. A rotation adjustment component is provided on one side of the movable adjustment component on the surface of the mounting column 101. A reinforcement installation component is provided at the connection between the end of the movable adjustment component and the inside of the fixed plate 102. When the cabinet door is closed on the explosion-proof cabinet, the uniform force-bearing reinforcement mechanism reinforces both ends of one side of the cabinet door and the end of the explosion-proof cabinet. It is less prone to instability and remains more stable and reinforced after long-term use.

[0026] In order to facilitate the simultaneous movement and reinforcement of the two bolt posts 1023 by means of the movable adjustment assembly, in this embodiment, preferably, the movable adjustment assembly includes a bidirectional lead screw 1025 that rotates inside the mounting post 101. The end of the bidirectional lead screw 1025 is provided with a movable post 1024 inside the mounting post 101. When the bidirectional lead screw 1025 rotates, it drives the movable post 1024 to move. The movement of the movable post 1024 drives the bolt posts 1023 to move and engage.

[0027] To facilitate the rotational adjustment of the bidirectional lead screw 1025 via the rotational adjustment assembly, in this embodiment, preferably, the rotational adjustment assembly includes a rotating rod 1021 rotatably connected to the front surface of the mounting post 101. One end of the rotating rod 1021 is fixed with a torsion gear 1026 inside the mounting post 101, and the other end of the rotating rod 1021 has an internal hexagonal slot. A torsion gear 1027 is fixed at the middle position of the bidirectional lead screw 1025. The surfaces of the torsion gear 1026 and the torsion gear 1027 mesh. When the rotating rod 1021 drives the torsion gear 1026 to rotate, the torsion gear 1026 rotates and meshes with the surface of the torsion gear 1027, thereby driving the bidirectional lead screw 1025 to rotate and adjust.

[0028] In order to facilitate the reinforcement of both ends of the cabinet door and the cabinet body by means of the reinforcement installation component, in this embodiment, preferably, the reinforcement installation component includes a limiting movement groove 1022 opened inside both ends of the installation column 101. The door bolt 1023 is fixed inside the limiting movement groove 1022 at the end of the moving column 1024. The fixing plate 102 has a bolt hole 1028 opened inside, and the end of the door bolt 1023 is engaged with the inside of the bolt hole 1028. When the moving column 1024 moves, it can drive the door bolt 1023 to move and engage inside the bolt hole 1028, so that the cabinet door can be locked and reinforced at both ends after closing.

[0029] The anti-rotation reinforcement mechanism includes a locking reinforcement component located in the middle of the movable adjustment component. A screw-in adjustment component is provided at the connection between the end of the locking reinforcement component and the surface of the mounting column 101. After the explosion-proof bolt body 100 is reinforced and installed, the anti-rotation reinforcement mechanism can reinforce the bidirectional screw 1025 to prevent it from rotating and loosening under force.

[0030] To facilitate the reinforcement and installation of the bidirectional lead screw 1025 using a locking and reinforcing assembly, in this embodiment, preferably, the locking and reinforcing assembly includes an inner tooth engagement plate 1012 located at the middle position inside the mounting post 101 on the surface of the bidirectional lead screw 1025. A pull plate 1013 is fixed to the end of the inner tooth engagement plate 1012, and the inner surface of the inner tooth engagement plate 1012 contacts the outer surface of the bidirectional lead screw 1025. After the bidirectional lead screw 1025 is rotated and adjusted, the pull plate 1013 drives the inner tooth engagement plate 1012 to pull and adjust, clamping it on the surface of the bidirectional lead screw 1025 for reinforcement and installation, preventing rotational loosening.

[0031] In order to facilitate the pulling and reinforcing installation of the pull plate 1013 and the internal tooth occlusal plate 1012 by means of the screw-in adjustment assembly, in this embodiment, preferably, the screw-in adjustment assembly includes an adjustment bolt 1011 threadedly connected to the middle position of the front surface of the mounting post 101, and the end of the adjustment bolt 1011 is rotatably connected to the middle position of the end of the pull plate 1013 by a rotating ring. When the adjustment bolt 1011 is rotated, the pull plate 1013 and the internal tooth occlusal plate 1012 can be pulled and reinforced on the surface of the bidirectional lead screw 1025, which facilitates the reinforcement installation and prevents rotation.

[0032] The working principle and usage process of this utility model: When using this type of explosion-proof cabinet door bolt assembly, the installation process begins by fixing the mounting post 101 to one side of the explosion-proof cabinet door. Then, the fixing plate 102 is closed at both ends of one side of the explosion-proof cabinet. Therefore, after installation, the end of the rotating rod 1021 is closed on the outer surface of the cabinet door. After the cabinet door is closed on the surface of the explosion-proof cabinet, a wrench engages with the end of the rotating rod 1021, causing the rotating rod 1021 to rotate with the first torsion gear 1026. When the first torsion gear 1026 rotates, it meshes with the surface of the second torsion gear 1027. The double-acting screw 1025 rotates, which drives the two moving columns 1024 to move towards each other. When the moving columns 1024 move, they drive the bolt column 1023 to move inside the limiting moving groove 1022 until the bolt column 1023 is engaged inside the bolt hole 1028 to reinforce the cabinet door. This facilitates the reinforcement and explosion-proof installation, ensuring that both ends of the cabinet door are reinforced and explosion-proof. Long-term use is less prone to instability and the reinforcement remains more stable, improving the reinforcement and explosion-proof effect of the explosion-proof bolt body 100 installed on the explosion-proof cabinet.

[0033] Then, when the explosion-proof door bolt body 100 is installed in the explosion-proof reinforcement, the end of the adjusting bolt 1011 is located on the surface of the cabinet door and embedded inside. After the adjustment and reinforcement installation, the wrench is engaged on the surface of the adjusting bolt 1011 again and screwed in for adjustment. When the adjusting bolt 1011 is rotated for adjustment, it pulls the pull plate 1013 and the internal tooth engagement plate 1012 to move. The inner surface of the internal tooth engagement plate 1012 moves and engages with the outer surface of the double-acting screw 1025 for reinforcement installation. After reinforcement and engagement, it is easy to lock to prevent the double-acting screw 1025 from rotating and loosening. This results in a more stable reinforcement installation and improves the rotational reinforcement of the double-acting screw 1025 when the explosion-proof door bolt body 100 is installed in the explosion-proof cabinet.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
