Secret door with an outward opening angle greater than 150 degrees

Abstract

The invention discloses a blank door with an outward-opening angle larger than 150 degrees. The blank door comprises an outer frame (1), an inner frame (5) and a positioning assembly. The positioning assembly comprises an outer frame positioning part (91), an inner frame positioning part (92) and a positioning shaft (93). The outer frame (1) is fixed on a surrounding wall body connecting part I (2). The upper and lower sides of the outer frame (1) are fixed to the outer frame positioning part (91), and the matched position of the inner frame (5) and the outer frame (1) is fixed to the inner frame positioning part (92). The outer frame positioning part (91) and the inner frame positioning part (92) are provided with positioning holes, the inner frame (5) is fixed in the outer frame (1) through the positioning holes and the positioning shaft (93), and the front side of the inner frame (5) is fixed to a door leaf (8). The outward-opening angle of the blank door can be larger than 150 degrees, is flexible, free of sound, reliable in quality, free of maintenance and potential safety hazard and is not provided with matched parts on the appearance, the benefit is improved through batch production, the comprehensive cost is saved, and high-quality productization decoration is achieved.

Description

technical field [0001] The invention relates to a hidden door with an outward opening angle greater than 150 degrees. Background technique [0002] At present, there are still various tube wells and fire hydrant doors on the walls of many hotels, residences, and office buildings, which have a great impact on the overall sense of space. With the continuous improvement of decoration quality, secret door technology has been adopted in some engineering decoration, but the effect is still not ideal. [0003] Conventional methods have the following disadvantages: [0004] 1. On the wall of wallpaper or latex paint, such as wooden doors, the height of the doors on the whole wall is inconsistent, resulting in fragmented walls. [0005] 2. If the door is made of latex paint or wallpaper, the flatness, the size of the door gap, and the treatment of the corners are not easy to control. [0006] 3. Concealed hinge doors, if the opening angle does not reach 90 degrees, it will affect ...

AI Technical Summary

Problems solved by technology

[0004] 1. On the wallpaper or latex paint wall, such as wooden doors, the height of the overall wall door is inconsistent, resulting in fragmented walls

[0005] 2. If the door is made of latex paint or wallpaper surface, the flatness, the size of the door gap, and the treatment of the corners are not easy to control

[0006] 3. Concealed hinge door, if the opening angle is less than 90 degrees, it will affect the use of fire protection, maintenance requirements and the size of the gap formed by the door sagging

[0007] 4. The high maintenance rate of the above 2 and 3 increases the project cost

[0008] 5. There are door hardware on the surface that cannot meet the requirements of hidden doors
