Description

Technical Field

[0001] This utility model relates to the field of anti-collision door technology, specifically to an iron door with good anti-collision effect. Background Technology

[0002] Iron doors are doors made of materials such as sheet metal, square iron tubes, and round iron tubes welded together. According to their opening method, they include swing doors, sliding doors, and revolving doors. Among them, sliding doors are widely used because they occupy less space.

[0003] When a sliding door is locked, one side of the door moves within the track, while the other side is fixed to the door frame by the lock body. Its anti-collision effect is limited, so sliding doors with anti-collision function need further research. Utility Model Content

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] Example 1

[0028] Combined with appendix Figure 1-5 A type of iron door with good anti-collision effect includes a door frame 1 and a door body 2 that is movably installed inside the door frame 1. A fixing plate 3 that is symmetrically arranged and cooperates with the door body 2 is provided in the middle position of the door frame 1.

[0029] The inner side of the door frame 1 is provided with a fixing device 4 that can fix the door body 2 on the fixing plate 3;

[0030] The door body 2 includes a door shell 5 and several reinforcing plates 6 that are welded and fixed inside the door shell 5 in a cross pattern. The inner side of the door shell 5 is provided with a handle 7 to facilitate opening the door body 2.

[0031] The door body 2 is formed by interlocking and welding a door shell 5 and several reinforcing plates 6 arranged in a crisscross pattern. When the door body 2 is impacted, the reinforcing plates 6 deform longitudinally and can withstand a high impact force, thereby improving the anti-collision effect of the door body 2. The fixing device 4 can fix the door body 2 when it is closed to prevent the door body 2 from being pried open.

[0032] The bottom of the door 2 is provided with cross-arranged rollers 10 and anti-pry blocks 11.

[0033] One end of the door frame 1 is provided with a through hole 8 to facilitate the entry of the door body 2 into the door frame 1. A baffle 9 is provided inside the through hole 8. The through hole 8 facilitates the installation of the door body into the door frame 1, so that the top and bottom of the door body 2 are fitted with the door frame, preventing the door body 2 from being pried open from the outer gap.

[0034] The fixing device 4 includes a plurality of evenly arranged fixing holes 12 that penetrate the fixing plate 3. The fixing plate 3 is provided with a U-shaped part 13, the U-shaped part 13 is provided with an opening 14, the U-shaped part 13 is provided with a vertical rod 15, the vertical rod 15 is provided with a plurality of fixing rods 16 that are movably provided in the fixing holes 12, and the vertical rod 15 is provided with a T-shaped handle 17 provided in the opening 14.

[0035] The fixing plate 3 is provided with a cylinder 18 that cooperates with the fixing hole 12 to prevent the fixing rod 16 from falling out.

[0036] When a person pulls the T-shaped handle 17, the T-shaped handle 17 causes the vertical rod 15 and the fixing rod 16 to disengage from the fixing hole 12, thus opening the door. Pushing the T-shaped handle 17 causes the fixing rod 16 to move into the fixing hole 12, where the fixing rod 16 blocks the door 2 and locks it. The cylinder 18 prevents the fixing rod 16 from falling out of the fixing hole 12 when it disengages.

[0037] The reinforcing plate 6 includes a first reinforcing plate 19 and a second reinforcing plate 20 that interlock with each other. Both the first reinforcing plate 19 and the second reinforcing plate 20 are provided with interlocking notches 21. The first reinforcing plate 19 and the second reinforcing plate 20 are interlocked and welded together. When the door body 2 is impacted, the first reinforcing plate 19 and the second reinforcing plate 20 deform longitudinally, providing a high anti-collision function.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, alterations, deletions of some features, additions of features, or recombinations of features to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the innovative principles of the present invention shall still fall within the scope of the technical solutions of the present invention.
