Description

Technical Field

[0001] This utility model relates to the field of security door technology, specifically a security door with a steel front and wooden back panel. Background Technology

[0002] A security door, also known as a burglarproof security door, combines the functions of theft prevention and security. Equipped with a burglarproof lock, it can resist unauthorized opening under certain conditions for a certain period of time. It possesses a certain level of security protection and meets the corresponding burglarproof security level. Security doors can be made of different materials, but only those that meet standard testing requirements and obtain a production license for security products can be called security doors. To enhance the aesthetics of security doors after installation, steel-front, wood-backed security doors with inserts have appeared on the market. These inserts enhance the door's sealing, preventing unauthorized personnel from entering the room through the door gaps, thus providing additional security. Furthermore, a variety of inserts are available, with different styles and colors to choose from, satisfying both decorative needs and enhancing the room's aesthetics.

[0003] Currently, the sound insulation effect of existing steel-front and wood-back panel security doors is not ideal. When the security door is closed, gaps are often left between the security door and the frame. The existence of these gaps greatly reduces the sound insulation and heat preservation capabilities of the security door. Therefore, we propose a steel-front and wood-back panel security door. Utility Model Content

[0004] The purpose of this utility model is to provide a front steel and rear wood panel security door, which has the advantages of good sound insulation and heat preservation. It solves the problem that the sound insulation effect of existing front steel and rear wood panel security doors is not ideal, and that gaps are often left between the security door and the frame when the security door is closed. The existence of these gaps greatly reduces the sound insulation and heat preservation capabilities of the security door.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a front steel and rear wooden insert security door, comprising an outer protective frame, a wooden insert protective plate inserted into the front of the outer protective frame, an inner protective frame inserted into the front end of the wooden insert protective plate, a door body movably connected to the left end of the inner side of the outer protective frame via a hinge, a square groove provided on the outer side of the door body, an elastic rubber bladder adhered to the inner side of the square groove, an L-shaped edge protection provided on the rear side of the door body, a sealing rubber bladder provided between the L-shaped edge protection and the outer protective frame, and a connecting pipe provided between the sealing rubber bladder and the elastic rubber bladder.

[0006] Preferably, both the inner and outer protective frames are made of stainless steel.

[0007] Preferably, a combination lock body and a handle are fixedly installed on the right side of the rear side of the door from top to bottom.

[0008] Preferably, the sealing rubber bladder is fixedly connected to the L-shaped guard.

[0009] Preferably, there are multiple connecting pipes, and the distance between any two adjacent connecting pipes is equal.

[0010] Preferably, the sealing rubber bladder is a hollow L-shaped structure, and the elastic rubber bladder is a hollow square-shaped structure.

[0011] Preferably, the inner side of the door is filled with a layer of rock wool and a layer of centrifugal glass wool from front to back, and the inner side of the outer protective frame is bonded with a cushioning pad.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. When the door is closed by the handle, the door can move the L-shaped guard synchronously. When the L-shaped guard moves the sealing rubber bladder to contact the rear side of the outer frame, the sealing rubber bladder is compressed, and the front of the door can fit against the buffer pad, thus providing a door-closing buffer. When the sealing rubber bladder is compressed, the gas inside can enter the elastic rubber bladder through the connecting pipe. When the door and the outer frame are closed and locked, the gas in the elastic rubber bladder can expand, and the expansion range can fill the gap between the inner frame and the door. With the assistance of the compressed sealing rubber bladder and the buffer pad for door-closing buffer, this security door has triple sealing protection, minimizing the existence of gaps, thereby improving the heat insulation and sound insulation effect of this security door.

[0014] 2. This utility model improves the sound insulation and heat preservation effect of the door itself by setting up a rock wool layer and a centrifugal glass wool layer. Attached Figure Description
