Description

Technical Field

[0001] This utility model relates to the field of security door technology, specifically a tightly connected security door. Background Technology

[0002] A security door, also known as a burglarproof security door, is a door that can resist unauthorized opening for a certain period of time, possessing anti-theft and security features. Security doors can be made of different materials, including steel, steel-wood structure, stainless steel, aluminum alloy, and copper. Different materials have different performance characteristics and advantages and disadvantages. For example, aluminum alloy security doors are widely popular due to their lightweight, sturdiness, aesthetics, and durability.

[0003] For example, a Chinese invention, CN111894415B, provides a "high-end embedded anti-theft door". This application includes an anti-theft door body and an anti-theft door frame. The anti-theft door body is installed on the inner side of the anti-theft door frame via hinges. An anti-theft door lock is located in the middle of the front of the anti-theft door body. A lock cylinder is located on the inner side of the anti-theft door lock. A movable latch is movably connected to one side of the lock cylinder. An embedded latch is located in the inner cavity of the anti-theft door body near the top of the anti-theft door lock. In this invention, when the movable latch rebounds through a forced tool, it pushes the anti-theft card. The anti-theft card connects to a second power supply and a second electromagnet. The second electromagnet generates attraction, causing the pad to move towards the side of the second electromagnet. The spring rod can fall into the spring groove. At this time, the compressed spring can push the embedded latch, causing the embedded latch to embed into the latch groove, ensuring a tight connection between the anti-theft door body and the anti-theft door frame, thus improving the anti-theft effect.

[0004] The security doors described above lack an effective sealing structure between the door frame and the door body during use, which easily leads to gaps between them, severely affecting the overall sound insulation and sealing effect, thus failing to meet the needs of users. Utility Model Content

[0005] The purpose of this utility model is to provide a tightly connected security door with a multi-layer sealing structure, which effectively improves the sealing performance and sound insulation effect of the security door after it is locked.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tightly connected security door, comprising a security door body and a security door frame, wherein rubber side pads are fixedly connected around the perimeter of the inner cavity of the security door frame, a second arc-shaped rubber pad is fixedly connected around the perimeter of the inner cavity of the rubber side pads, a sealing frame is fixedly connected around the perimeter of the inner cavity of the security door frame and behind the rubber side pads, a connecting pipe is fixedly connected between the surface of the sealing frame and the surface of the rubber side pads, an air guide groove is provided around the perimeter of the front surface of the sealing frame, a rubber pressure strip is movably connected to the surface of the air guide groove, and a first arc-shaped rubber pad is fixedly connected between the perimeter of the front surface of the rubber pressure strip and the perimeter of the front surface of the sealing frame.

[0007] As a preferred embodiment, a fiberglass wool board is fixedly connected to the right side of the inner cavity of the security door, and a PU foam board is fixedly connected between the left side of the fiberglass wool board and the left side of the inner cavity of the security door.

[0008] As a preferred embodiment, an anti-theft lock is fixedly installed at the middle of the front surface of the anti-theft door, and a peephole is fixedly installed at the top of the anti-theft door.

[0009] As a preferred embodiment, a metal hinge is fixedly installed on the left end of the front surface of the security door frame, and the right side of the metal hinge is fixedly installed on the left side of the outer surface of the security door.

[0010] As a preferred embodiment, an edge sealing strip is fixedly connected to the four sides of the outer surface of the security door frame, and a rubber sealing gasket is fixedly connected to the four sides of the front surface of the edge sealing strip.

[0011] As a preferred embodiment, a return spring is fixedly connected between the back of the rubber strip and the surface of the air guide groove.

[0012] As a preferred embodiment, the number of the second arc-shaped rubber pads is three, and the distance between two adjacent second arc-shaped rubber pads is equal.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, through the setting of a sealing frame, a first arc-shaped rubber pad, a second arc-shaped rubber pad, and rubber side pads, can effectively achieve multiple seals at the joint between the security door body and the security door frame during the locking process. This effectively avoids gaps between the security door body and the security door frame, ensuring a tight connection between them. This effectively improves the sound insulation and sealing performance between the security door body and the security door frame. Furthermore, during the locking process, the security door body can contact the first arc-shaped rubber pad, and while compressing the first arc-shaped rubber pad, it can push the rubber pressure strip along the surface of the air guide groove. The movement of the rubber pressure strip can push the air inside the air guide groove into the interior of the second arc-shaped rubber pad through the connecting pipe, causing the second arc-shaped rubber pad to expand in volume and effectively adhere to the surface of the security door body. This further improves the sealing performance of the connection between the security door body and the security door frame, greatly satisfying the user's needs.

[0015] 2. This utility model, through the installation of fiberglass cotton board and PU foam board, forms a double-layer thermal insulation and soundproofing protection inside the security door, effectively improving the thermal insulation and soundproofing performance of the security door. The installation of anti-theft lock facilitates the locking of the security door and the security door frame. The installation of peephole facilitates the observation of the outside of the room. The installation of metal hinges achieves the purpose of connecting the security door and the security door frame.

[0016] 3. This utility model, through the setting of edge sealing strip and rubber sealing gasket, can effectively seal the edge of the anti-theft door frame and the wall during the overall installation process. Through the setting of return spring, elastic support can be formed on the back of the rubber pressure strip, so that during the subsequent opening between the anti-theft door and the anti-theft door frame, the return spring can push the rubber pressure strip and the first arc-shaped rubber gasket to move and reset.
