Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft door production, and particularly relates to an anti-theft door with good sound insulation effect. Background Technique

[0002] The interior of an anti-theft door is usually filled with high-efficiency sound insulation materials, such as high-density rock wool, glass fiber cotton or special sound insulation foam, etc. These materials can absorb and block the transmission of sound, reducing the external noise to the lowest level. At the same time, rubber strips or silicone strips with excellent sealing performance are installed around the door frame to ensure that the gap between the door and the door frame is tightly sealed, preventing sound from penetrating through the gap.

[0003] Over time, the sealing pads on the outer surface of the anti-theft door frame gradually age. In order to maintain the good sound insulation and sealing effects of the anti-theft door, it is necessary to replace the aging sealing pads. In the current replacement operation, after separating the aging sealing pads from the door frame, it is necessary to clean the residual glue on the outer surface of the door frame. Since the space between the door frame and the door body is usually small, workers need to operate difficultly in a narrow space during the process of removing the residual glue and installing the new sealing pads. Not only is the work efficiency low, but also operation errors are likely to occur, resulting in the sealing pads being installed insecurely or unevenly, causing the situation of poor sealing of the anti-theft door. Therefore, there is a problem that it is not convenient to replace the sealing pads. Content of the Utility Model

[0004] The main purpose of the utility model is to provide an anti-theft door with good sound insulation effect, which can effectively solve the problems put forward in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieved purposes and functions of the utility model easy to understand, the utility model will be further described below in conjunction with specific embodiments.

[0022] Such asFigure 1 - Figure 4 As shown in Figure 4 , a burglary-proof door with good sound insulation effect includes a door frame 1, a sound insulation mechanism 2 and a disassembly and assembly mechanism 3. The outer surface of the sound insulation mechanism 2 is hinged to the inner side surface of the door frame 1, and the outer surface of the disassembly and assembly mechanism 3 is attached to the outer surface of the door frame 1. The disassembly and assembly mechanism 3 includes a mounting frame 302 attached to the outer surface of the door frame 1. A card slot 304 is provided on the outer surface of the door frame 1, and a mounting groove 303 is provided on the outer surface of the mounting frame 302. A snap spring 306 is fixedly connected to the outer surface of the mounting frame 302 away from the mounting groove 303, and a fixing protrusion 305 is fixedly connected to the outer surface of the snap spring 306.

[0023] In order to facilitate the replacement of the gasket, a gasket 301 is clamped on the outer surface of the mounting groove 303. The outer surface of the gasket 301 is attached to the outer surface of the burglary-proof door housing 201. By attaching the outer surface of the gasket 301 to the outer surface of the burglary-proof door housing 201, it is convenient to increase the sealing performance between the door frame 1 and the burglary-proof door housing 201. The outer surface of the fixing protrusion 305 is slidably connected to the outer surface of the card slot 304. The snap spring 306 and the fixing protrusion 305 facilitate the clamping of the mounting frame 302, and thus facilitate the disassembly and replacement of the mounting frame 302. The cross-section of the mounting groove 303 is a convex structure, and a convex protrusion is provided on the outer surface of the gasket 301. By pulling the outer surface of the gasket 301 and then exerting force to pull, the gasket 301 can drive the mounting frame 302 to move, and thus facilitate the separation of the fixing protrusion 305 and the card slot 304. The snap spring 306 and the fixing protrusion 305 are both made of plastic structure, and the fixing protrusion 305 and the snap spring 306 are integrally formed structures. The fixing protrusion 305 and the snap spring 306 facilitate the limitation of the mounting frame 302, and thus facilitate the replacement of the gasket 301.

[0024] It is worth mentioning that by pulling the outer surface of the gasket 301 and then exerting force to pull backward, it is convenient to disassemble the mounting frame 302. Then pull the gasket 301 to one side to separate the gasket 301 from the mounting frame 302, which is convenient to disassemble the old and damaged gasket 301. Then snap the new gasket 301 into the mounting groove 303, which is convenient to replace the gasket 301. Then insert the fixing protrusion 305 into the card slot 304, and then pat the outer surface of the card slot 304, which is convenient to clamp the fixing protrusion 305 in the card slot 304, and thus convenient to replace the gasket 301 and improve the sound insulation performance of the burglary-proof door.

[0025] In order to enhance the strength of the anti-theft door, the sound insulation mechanism 2 includes an anti-theft door outer shell 201 hinged to the outer surface of the door frame 1. The inner wall of the anti-theft door outer shell 201 is filled with multiple groups of sound insulation boards 203. Among them, a fixed frame 202 is fixedly connected to the inner wall of the anti-theft door outer shell 201, and the outer surface of the fixed frame 202 is fixedly connected to the outer surface of the sound insulation board 203. The fixed frame 202 facilitates increasing the strength of the door frame 1.

[0026] It is worth mentioning that the fixed frame 202 facilitates increasing the strength of the anti-theft door outer shell 201, and the sound insulation board 203 facilitates increasing the sound insulation performance of the anti-theft door outer shell 201.

[0027] Working principle: Pull the outer surface of the sealing gasket 301, and then exert force to pull it backward. The sealing gasket 301 drives the mounting frame 302 to move, so that the fixed protrusion 305 slides on the outer surface of the card slot 304, and then the snap spring 306 returns to its original position, facilitating the disassembly of the mounting frame 302. Then pull the sealing gasket 301 to one side, so that the sealing gasket 301 and the mounting frame 302 are separated, facilitating the disassembly of the old and damaged sealing gasket 301. Then snap the new sealing gasket 301 into the mounting groove 303, facilitating the replacement of the sealing gasket 301. Then insert the fixed protrusion 305 into the card slot 304, and then pat the outer surface of the card slot 304, so that the fixed protrusion 305 slides into the card slot 304, and at the same time the snap spring 306 deforms, thus facilitating the clamping of the fixed protrusion 305 in the card slot 304 and facilitating the positioning of the mounting frame 302. The fixed frame 202 facilitates increasing the strength of the anti-theft door outer shell 201, and the sound insulation board 203 facilitates increasing the sound insulation performance of the anti-theft door outer shell 201.
