Description

Technical Field

[0001] The utility model belongs to the field of door body structures, and in particular relates to an improved entrance door. Background Art

[0002] In modern residential buildings, entrance doors, as an important part connecting indoor and outdoor environments, not only need to have basic safety and isolation functions, but also need to have good insulation, sound insulation, aesthetics, weather resistance, etc. With the improvement of living standards, people's performance requirements for entrance doors are getting higher and higher.

[0003] Traditionally, many residential entrance doors are made of color steel plates. Color steel plates have been widely used in the production of entrance doors for a period of time due to their relatively low cost, simple manufacturing process and convenient installation. However, color steel plate door panels have the following significant disadvantages:

[0004] 1. Poor thermal insulation effect: The thermal conductivity coefficient of the color steel plate is relatively high, which results in it being unable to effectively isolate the temperature difference between outdoor and indoor areas in a living environment that is warm in winter and cool in summer, thus affecting the living comfort.

[0005] 2. Easy to corrode: Especially in coastal areas or rainy environments, color steel plates are prone to corrosion due to moisture, which in turn affects the structural strength and service life of the door. Over time, rust and marks may appear on the surface of the color steel plates due to corrosion or scratches, affecting the overall aesthetics.

[0006] Therefore, the market demand for entrance doors with better thermal insulation, weather resistance and aesthetics is increasing. In view of the defects of color steel plates, the industry urgently needs to develop door panels made of new materials to improve the overall performance of entrance doors and meet consumers' pursuit of high-quality life.

The door panel 10 comprises an EPS board 11, and an anti-corrosion board 12 is bonded to the front and back surfaces of the EPS board 11. The door frame 20 is equipped with a mounting seat 30 for assembling a door lock on one side of the door panel 10. The EPS board 11 is made of expandable polystyrene, which is light in weight and has good thermal insulation performance. The anti-corrosion board 12 is made of one of an aluminum alloy board and an FRP board. The surface of the aluminum alloy material can be sprayed with a water-based paint, and the water-based paint is a PVDF water-based paint that is chemically resistant, UV-resistant, heat-resistant and wear-resistant. For example, the inner door panel 10 is made of an aluminum alloy board, and the outer door panel 10 is made of an FRP board. The FRP board is made of glass fiber reinforced plastic. The FRP board and the aluminum alloy board have good corrosion resistance and can effectively protect the door panel 10. The structural design of the door panel 10 composed of the EPS board 11, the aluminum alloy board and the FRP board can effectively prevent the door panel 10 from being corroded, and has excellent thermal insulation performance.

[0032] In the present utility model, the specific structure of the door frame 20 is as follows: the door frame 20 is welded by a plurality of aluminum profiles 21, and the end faces of the aluminum profiles 21 used to connect adjacent aluminum profiles 21 are inclined at 45 degrees. This design is conducive to the connection between the aluminum profiles 21, and can ensure the overall structural stability of the door frame 20, and avoid deformation of the door frame 20. The door frame 20 is equipped with a hinge 22 on one side used to connect the wall. The hinge 22 is a damping rotation structure, which is conducive to reducing vibration and noise, and reducing the rotation wear of the hinge 22. The upper and lower ends of the hinge 22 are equipped with a sheath 23. The design of the sheath 23 can effectively prevent the hinge 22 from wearing, and avoid the overall sinking of the entrance door due to the wear of the hinge 22. A limited edge is set on the door frame 20, and the limited edge prevents the door body from rotating indoors by limiting the relative position of the entrance door and the wall.

[0033] In the utility model, the door panel 10 is equipped with fixing plates 13 around it, so that the connection between the EPS board 11 and the anti-corrosion board 12 is firm and debonding is avoided. The EPS board 11 is equipped with ASA strips 14 around it, and the ASA strips 14 are located in the space surrounded by the EPS board 11, the anti-corrosion board 12 and the fixing plate 13. ASA material is an impact-modified resin copolymerized by styrene, acrylonitrile and acrylic rubber, which has excellent weather resistance, heat resistance, chemical corrosion resistance, good impact resistance and color stability. The design of the ASA strips 14 is conducive to strengthening the strength of the entrance door. The fixing plate 13 is equipped with a sealing strip 25, and the sealing strip 25 is assembled and connected with the door frame 20. The sealing strip 25 can prevent dust, liquid, etc. from entering the door frame 20 and the door panel 10.

[0034] Preferably, the mounting base 30 and the protective cover 23 described in the present invention can be made of plastic material to reduce the overall weight of the entrance door and reduce the production cost of the entrance door.

[0035] refer to Figure 6 As another embodiment of the present invention, the mounting seat 30 is exposed from the front and back surfaces of the door panel 10. This design is conducive to the disassembly and assembly of the door lock and can avoid damage to the aluminum alloy plate and the FRP plate when disassembling and assembling the door lock.
