Description

Technical Field

[0001] The utility model belongs to the technical field of anti-theft doors, and in particular relates to an anti-theft door with strong impact resistance. Background Art

[0002] The anti-theft door, full name "anti-theft safety door", has both anti-theft and safety performance. It is equipped with an anti-theft lock, which can resist abnormal opening under certain conditions within a certain period of time, has certain safety protection performance and meets the corresponding anti-theft safety level. According to the "General Technical Conditions for Anti-theft Safety Doors", qualified anti-theft doors cannot be pried open or open a 615 square centimeter opening on the door leaf within 15 minutes using ordinary hand tools such as chisels, screwdrivers, crowbars, and portable power tools such as hand drills, or open a 38 square millimeter opening within a semicircle of 150 square millimeters at the locking point. In addition, the locks used on anti-theft doors must be special anti-theft door locks with anti-drilling functions that have passed the inspection of the Ministry of Public Security Testing Center.

[0003] The impact resistance of common anti-theft doors on the market still needs to be improved. Once impacted, these doors are often unable to effectively conduct and disperse the impact, resulting in almost all the impact acting directly on the door body. This deficiency greatly reduces the effectiveness and safety of anti-theft doors in actual use, and severely limits their protective capabilities. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-theft door with strong impact resistance, which can conduct the impact force. This conduction helps to disperse the impact force and reduce the direct impact on a single part, thereby improving the stability and safety of the entire structure of the anti-theft door.

[0005] The technical solutions adopted in this utility are as follows:

[0006] A highly impact-resistant anti-theft door comprises a door frame, an inner side of which is rotatably mounted a door body via hinges, the number of the hinges being at least three, a buffer cavity being arranged inside the door body, a plurality of horizontal plates being arranged in a vertical array inside the buffer cavity, a plurality of vertical tubes being fixed between the plurality of horizontal plates, a plurality of guide grooves being penetrated through the inner top wall and the inner bottom wall of the buffer cavity, an extrusion block being slidably mounted inside the guide groove, a sliding block being slidably connected to the vertical tube being fixed to one side of the extrusion block, an arc-shaped steel plate being arranged between the upper and lower extrusion blocks, and a rubber block in contact with the arc-shaped steel plate being arranged on one side of the horizontal plate.

[0007] Furthermore, the arc-shaped steel plate is a 304 stainless steel plate with a thickness of 0.8-1.2 mm, the vertical pipe is made of alloy steel, and the outer diameter of the vertical pipe is 80 mm and the wall thickness is 6 mm.

[0008] Furthermore, the convex surface of the arc-shaped steel plate is provided with a plurality of reinforcing rings fixed to the inner side of the buffer cavity.

[0009] Furthermore, a limiting strip which can limit the position of the door body is arranged on the inner side of the door frame.

[0010] The technical effects achieved by this utility model are:

[0011] The utility model discloses an anti-theft door with strong impact resistance, in which an arc-shaped steel plate is arranged. When the door body is subjected to impact force, the impact force will cause the two ends of the arc-shaped steel plate to move outwards, that is, the so-called "opening" or "expansion" phenomenon occurs, and push the extrusion block to move. The extrusion block is squeezed on the inner side of the door frame to conduct the impact force. Such conduction helps to disperse the impact force and reduce the direct impact on a single part, thereby improving the stability and safety of the entire structure of the anti-theft door.

[0017] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0018] like Figure 1-3As shown, an anti-theft door with strong impact resistance includes a door frame 1, a door body 2 is rotatably installed on the inner side of the door frame 1 through hinges, the number of hinges is at least three, and the stability of the connection between the door body 2 and the door frame 1 is improved. A buffer cavity 6 is arranged inside the door body 2, and the buffer cavity 6 is filled with foam plastic filler to improve the buffering effect of the door body 2. A plurality of horizontal plates 7 are arranged in a vertical array on the inner side of the buffer cavity 6, and a plurality of vertical pipes 8 are fixed between the plurality of horizontal plates 7. A plurality of guide grooves 11 are opened through the inner top wall and the inner bottom wall of the buffer cavity 6, and an extrusion block 10 is slidably installed inside the guide groove 11. A slider 9 slidably connected to the vertical pipe 8 is fixed on one side of the extrusion block 10, and an arc-shaped steel plate 12 is arranged between the upper and lower extrusion blocks 10. When the arc-shaped steel plate 12 is subjected to impact force, the impact force will cause the two ends of the arc-shaped steel plate 12 to move outward, that is, the so-called "opening" or "expansion" phenomenon occurs, and the extrusion block 10 is pushed to move. The extrusion block 10 is squeezed on the inner side of the door frame 1 to conduct the impact force, which helps to disperse the impact force and reduce the direct impact on a single part, thereby improving the stability and safety of the entire structure of the anti-theft door. A rubber block 14 in contact with the curved steel plate 12 is provided on one side of the cross plate 7. The rubber block 14 can buffer the curved steel plate 12, thereby improving the impact resistance of the anti-theft door. The structure is simple, which improves the anti-collision and anti-theft capabilities of the anti-theft door, helps to prevent the door body 2 from deforming or loosening when subjected to external pressure or force, and ensures the stability and reliability of the door body 2; the curved steel plate 12 is a 304 stainless steel plate with a thickness of 0.8-1.2mm, which improves the strength and toughness of the curved steel plate 12. The vertical pipe 8 is made of alloy steel, and the outer diameter of the vertical pipe 8 is 80mm and the wall thickness is 6mm, which increases the structural strength of the door body 2 and further improves the anti-collision and anti-theft capabilities.

[0019] The convex surface of the arc-shaped steel plate 12 is provided with a plurality of reinforcing rings 13 fixed to the inner side of the buffer cavity 6, which further improves the strength and stability of the connection between the arc-shaped steel plate 12 and the buffer cavity. The reinforcing rings 13 are provided in a circular contact, and the force effect is relatively uniform, thereby improving the strength of the door body 2;

[0020] The inner side of the door frame 1 is provided with a limit strip 15 which can limit the door body 2, further increasing the anti-collision strength of the anti-theft door, and can limit the rotation of the door body 2, further improving the safety of the door body 2;

[0021] A door lock 3 is provided on one side of the door body 2. The door lock 3 is convenient for fixing the anti-theft door and improving the safety of the equipment. A cat's eye observation block 4 is fixed on the outer wall of the door body 2 and located on one side of the door lock 3. The cat's eye observation block 4 allows people in the house to clearly observe people outside the door without opening the door, so as to judge the true identity of the visitor and avoid unnecessary security risks; a doorbell button 5 is provided on the outer wall of the door body 2 and located below the cat's eye observation block 4, which provides a way for visitors to notify people in the house so that they know that someone is visiting, which is relatively complete.

[0022] The working principle of the utility model is as follows: when the door body 2 is subjected to impact force, the impact force is transmitted to the arc-shaped steel plate 12. When the arc-shaped steel plate 12 is subjected to the impact force, the impact force will cause the two ends of the arc-shaped steel plate 12 to move outward, that is, the so-called "opening" or "expansion" phenomenon occurs, and pushes the extrusion block 10 to move. The extrusion block 10 is squeezed on the inner side of the door frame 1 to conduct the impact force. This conduction helps to disperse the impact force and reduce the direct impact on a single part, thereby improving the stability and safety of the entire structure of the anti-theft door.

[0023] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
