Description

Technical Field

[0001] This utility model relates to the field of armored entrance door technology, specifically to an armored entrance door with anti-pinch function. Background Technology

[0002] A door refers to the entrance or exit of a building, or a device installed at the entrance or exit that can be opened and closed. A door is a physical entity that divides a limited space, and its function is to connect and close the entrances or exits of two or more spaces. Armored doors, on the other hand, use steel security doors as their basic core, while leveraging the high plasticity of wood and utilizing the flexibility of woodworking techniques.

[0003] In the prior art, patent document CN219176206U discloses an equipment using entrance door technology, including a door frame and a cover plate. The door frame has an internal mounting groove, within which a first flame-retardant board is laid. A gypsum board is laid on the side of the first flame-retardant board facing the cover plate, and a second flame-retardant board is laid on the cover plate opposite the gypsum board. A screw is provided in the mounting groove, and the first flame-retardant board and gypsum board are inserted into the screw. This invention, by laying the first flame-retardant board, gypsum board, and second flame-retardant board inside the door frame, forms a flame-retardant barrier, thereby preventing the spread of fire from the outside of the door frame into the entrance door, and also preventing the spread of fire from the inside of the entrance door outwards, thus isolating the fire and giving the entrance door a fireproof function.

[0004] To address the issue of flammable wood in armored doors made of steel and wood, existing technology involves laying a first flame-retardant board in the mounting groove of the door frame, then laying gypsum board on one side of the first flame-retardant board, and finally laying a second flame-retardant board on one side of the cover plate. However, this method still has the problem of fingers being pinched during use. Utility Model Content

[0005] The purpose of this invention is to provide an armored entrance door with anti-pinch function to solve the problems mentioned in the background art.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Example 1

[0028] like Figure 1-5As shown, this utility model provides an armored entrance door with anti-pinch function, including a door frame unit 1; and a door leaf unit 2 disposed on the outer surface of the door frame unit 1 for protection. The door frame unit 1 includes an installation assembly and a protective assembly disposed inside the installation assembly. The door leaf unit 2 includes a door leaf assembly disposed on the outer surface of the door frame unit 1 and a snap-fit ​​assembly 24 disposed on the outer surface of the door leaf assembly. The installation assembly includes a frame structure 11, the inner wall of which has an installation groove. The protective assembly includes a guide roller 13, the two ends of which are rotatably connected to the inner wall of the frame structure 11. An anti-pinch cloth strip 12 is rotatably connected to the outer surface of the guide roller 13, and a guide roller 14 is rotatably connected to the outer surface of the anti-pinch cloth strip 12. The two ends of the guide roller 14 are rotatably connected to the inner wall of the frame structure 11. One end of the anti-pinch cloth strip 12 is fixedly connected to... A take-up roller 15 is connected to the frame structure 11. Torque springs 16 are fixedly connected to both ends of the take-up roller 15. A rotating shaft seat 17 is fixedly connected to the other end of the torque spring 16. One end of the rotating shaft seat 17 is rotatably connected to the inner wall of the take-up roller 15. The outer surface of the rotating shaft seat 17 is detachably connected to the inner wall of the frame structure 11. When using the armored entrance door, the frame structure 11 is first installed in the reserved door opening. Then, the steel plate door 21 is installed inside the frame structure 11 using the hinges. At the same time, the anti-pinch cloth strip 12 is installed on the outer surface of the steel plate door 21. During the opening and closing of the steel plate door 21, the anti-pinch cloth strip 12 will stretch, so that the anti-pinch cloth strip 12 will cover the door gap. When the steel plate door 21 is closed, the anti-pinch cloth strip 12 can be wound up and stored by the cooperation of the take-up roller 15, the torque spring 16 and the rotating shaft seat 17.

[0029] Example 2

[0030] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the door assembly includes a steel plate door 21, the outer surface of the steel plate door 21 is rotatably connected to the inner wall of the frame structure 11, a protective steel plate 22 is fixedly connected to the inner and outer surfaces of the steel plate door 21, a door lock 23 is detachably connected to the inner wall of the steel plate door 21, a groove 221 is provided on the outer surface of the protective steel plate 22, and the snap-fit ​​assembly 24 includes a cover plate 241, the outer surface of the cover plate 241 is rotatably connected to the inner wall of the groove 221, and the inner wall of the groove 221 is... A rotating block 242 is rotatably connected, and a limiting block 243 is rotatably connected to the inner wall of the rotating block 242. When the steel plate door 21 is in the process of opening and closing, and remains in the open state for a long time, in order to effectively prevent the entrance door from being suddenly closed by external force and causing a hand to be pinched, the cover plate 241 can be rotated, and then the limiting block 243 and the rotating block 242 can be rotated to lock them onto the outer surface of the steel plate door 21. This allows a larger gap to be effectively created when the entrance door is closed, thereby preventing the entrance door from pinching a hand and playing a protective role.

[0031] The working principle of this armored entrance door with anti-pinch function will be explained in detail below.

[0032] like Figure 1-5 As shown, when using an armored entrance door, the frame structure 11 is first installed in the reserved door opening. Then, the steel plate door 21 is installed inside the frame structure 11 using the hinges. At the same time, the anti-pinch tape 12 is installed on the outer surface of the steel plate door 21. During the opening and closing of the steel plate door 21, the anti-pinch tape 12 will stretch, thus blocking the door gap. When the steel plate door 21 is closed, the anti-pinch tape 12 can be wound up and stored by the cooperation of the winding roller 15, the torque spring 16, and the rotating shaft seat 17. When the steel plate door 21 is in the opening and closing process and remains open for a long time, in order to effectively prevent the entrance door from being suddenly closed by external force and causing a hand to be pinched, the cover plate 241 can be rotated, and then the limiting block 243 and the rotating block 242 can be rotated to lock them onto the outer surface of the steel plate door 21. This effectively creates a larger gap when the entrance door is closed, thereby preventing the entrance door from pinching a hand and providing protection.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
