DETAILED DESCRIPTION

[0022] The following will be combined with the drawings of the specification to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only 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.

[0023] Embodiment 1: Combination Figure 1-Figure 4 As shown, the utility model provides a technical solution: an impact-resistant steel anti-theft door, comprising a door frame 1 and a door panel 4, wherein the door frame 1 and the door panel 4 are hinged by hinges;

[0024] A decorative panel 2, fixedly mounted on the outer end of the door panel 4;

[0025] The stabilizing frame 3 is provided with a plurality of them, all of which are fixedly installed inside the decorative plate 2. The first clamping plates 31 are slidably connected to the two sides of the stabilizing frame 3 in a transverse direction. The inner ends of the two first clamping plates 31 are fixedly connected to the arc-shaped plates 32. The inner ends of the arc-shaped plates 32 are rotatably connected to the pushing blocks 33. The other end of the pushing blocks 33 is rotatably connected to the second clamping plates 34. The second clamping plates 34 are slidably installed on the stabilizing frame 3 in a vertical direction. The first clamping grooves 35 corresponding to the first clamping plates 31 and the second clamping plates 34 are opened on the door frame 1.

[0026] The first clamping plate 31 is made of steel, and the shape of the first clamping plate 31 matches the shape of the first clamping slot 35 .

[0027] In the embodiment of the present invention, the decorative panel 2 is made of impact-resistant steel material, which can ensure that it can remain intact when subjected to external force impact. The arc plate 32 has an elastic force. When the decorative panel 2 is impacted by external force, it is recessed inward. This deformation causes the arc plate 32 to deform accordingly. At this time, the arc plate 32 will drive the first clamping plates 31 on both sides to move inward. This action not only enhances the impact resistance of the decorative panel, but also provides an additional protective layer for the door panel 4. In order to further enhance the stability of the door panel 4, the design also cleverly adds a matching push block 33 and a second clamping plate 34. When the decorative panel 2 is impacted and drives the first clamping plate 31 to move inward, the matching push block 33 will also play a role, pushing the second clamping plate 34 to move into the first clamping groove 35. This design enables the door panel 4 to quickly form a snap fit when subjected to external force impact, thereby effectively preventing the door panel 4 from being hit open by external forces. In addition, in order to improve the durability of the decorative panel, its surface is also specially treated to make it rust-proof and wear-resistant.

[0028] Embodiment 2: Combination Figure 3 , Figure 4 As shown, on the basis of the first embodiment, the door panel 4 is internally rotatably connected with a positioning shaft 51, the inner end of the positioning shaft 51 is fixedly connected with a turning handle 52, the outer wall of the positioning shaft 51 is fixedly connected with a gear 53, the tooth surface of the gear 53 is symmetrically meshed with two second racks 55 arranged in a vertical direction at one end away from the turning handle 52, and the tooth surface of the gear 53 is symmetrically meshed with two first racks 54 at one end close to the door frame 1, the other ends of the first rack 54 and the second rack 55 are fixedly connected with a clamping block 56, and a second clamping groove 57 corresponding to the clamping block 56 is provided on the door frame 1;

[0029] The first rack 54, the second rack 55 and the clamping block 56 are all slidably mounted in the door frame 1;

[0030] The clamping block 56 is made of steel, and the shape of the clamping block 56 matches the shape of the second clamping groove 57 .

[0031] In an embodiment of the present invention, when the door panel 4 needs to be self-locked, the positioning shaft 51 is driven to rotate by the turning handle 52, so that the positioning shaft 51 drives the gear 53 to rotate synchronously, and the gear 53 drives the first rack 54 and the second rack 55 to move outward, so that the first rack 54 and the second rack 55 drive the block 56 to slide outward, so that the block 56 is engaged with the second slot 57, thereby realizing all-round protection of the door panel 4 to prevent people from forcibly prying the door from outside; when it is necessary to release the self-locking of the door panel 4, it is only necessary to rotate the turning handle 52 in the opposite direction so that the block 56 disengages from the second slot 57 and enters the inside of the door panel 4.

[0032] Working principle of impact-resistant steel anti-theft door: When the decorative panel 2 is impacted by external force, it is sunken inwards. This deformation causes the arc plate 32 to deform accordingly. At this time, the arc plate 32 will drive the first clamping plates 31 on both sides to move inwards. This action not only enhances the impact resistance of the decorative panel, but also provides an additional protection layer for the door panel 4. At the same time, when the decorative panel 2 is impacted and drives the first clamping plate 31 to move inwards, the push block 33 will also play a role, pushing the second clamping plate 34 to move into the first clamping groove 35. This design enables the door panel 4 to quickly form a clamping when it is impacted by external force, thereby effectively preventing the door panel 4 from being hit open by external forces;

[0033] When the door panel 4 needs to be self-locked, the positioning shaft 51 is driven to rotate by the turning handle 52, so that the positioning shaft 51 drives the gear 53 to rotate synchronously, and the gear 53 drives the first rack 54 and the second rack 55 to move outward, so that the first rack 54 and the second rack 55 drive the block 56 to slide outward, so that the block 56 is engaged with the second slot 57, thereby realizing all-round protection of the door panel 4 to prevent people from forcibly prying the door from outside; when it is necessary to release the self-locking of the door panel 4, it is only necessary to rotate the turning handle 52 in the opposite direction to make the block 56 disengage from the second slot 57 and enter the inside of the door panel 4.

[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 the 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.
