Description

Technical Field

[0001] The present invention relates to the technical field of background wall decoration, and particularly to a background wall and an installation method thereof. Background Art

[0002] The floating background wall belongs to one type of background wall and is a common decorative wall in modern home decoration. Due to its unique design style and visual effect, it can add a sense of fashion and hierarchy to the space. By installing brackets or hangers on the wall, the background wall is fixed to the wall surface, forming a certain space between it and the wall surface, thus creating a floating effect. This installation method is applicable to background walls of various materials, but it is necessary to ensure that the wall can bear the weight of the background wall, and the installation process requires professional construction techniques to ensure the stability and safety of the background wall. Installing a hidden light strip inside the background wall can make the background wall present a soft halo at night, as if floating in the air. Moreover, a TV is installed in the viewing reserved hole of the floating background wall.

[0003] Currently, the installation method of the floating background wall is as follows: First, build a wooden dragon skeleton according to the drawings, then install a base board on the wooden dragon skeleton, and finally install the decorative board on the base board. The installation method is relatively cumbersome, affecting the installation efficiency. At the same time, after the installation is completed, it is also necessary to paste the light strip inside the background wall with double-sided tape or the like. This is not only inconvenient for its installation and fixation, affecting the installation efficiency, but also inconvenient for later disassembly. Moreover, it is not convenient to install the TV into the viewing reserved hole, which not only affects the installation efficiency but also is inconvenient for later cleaning, maintenance and replacement.

The rotation of the handwheel drives the rotation of the threaded rod, thereby driving the push plate to move downward. At this time, the push pin slides upward along the inclined groove. At the same time, the connecting block, connecting plate and L-shaped block can drive the mounting plate to move along the decorative panel away from the second metal frame, so that the telescopic plate is gradually compressed, and the mounting plate can be moved outward along the inner wall of the rectangular frame and moved to the outside. At this time, it is convenient to install and fix the TV on the mounting plate, making the installation of the TV more convenient and fast. Moreover, during subsequent maintenance, cleaning and replacement, it is also more convenient and fast. After the TV is installed, reverse the handwheel. At this time, the push plate can be driven to move upward and reset, so that the push pin moves downward along the inclined groove to reset, thereby driving the mounting plate and the TV to gradually move into the rectangular frame to ensure the installation effect.

At this time, the installation and fixation of the first metal frame and the wall are realized. Then, set the second metal frame on the side wall of the first metal frame and align the second installation hole with the first threaded hole. Then, insert the first bolt into the second installation hole and screw it into the first threaded hole to tighten and fix it, realizing the installation and fixation of the second metal frame and the first metal frame. Then, insert the rectangular frame into the second metal frame. At the same time, align the second bolt with the second threaded hole and tighten it to realize the installation and fixation of the decorative panel and the second metal frame, thus facilitating the assembly of the entire background wall and making the installation more convenient and fast.

[0016] (2) For this kind of background wall and its installation method, by setting the limiting mechanism, etc., after the second metal frame and the first metal frame are installed and fixed, the light strip can be attached to the light strip groove. When the light strip abuts against the top of the inclined plate, it can push the clamping block to move. At the same time, the first sleeve rod slides into the first sleeve, and the first spring is compressed. When the light strip abuts against the bottom of the light strip groove, under the action of the first spring, the first ball can abut against both sides of the light strip, thus facilitating the installation and limiting of the light strip. At the same time, through the setting of the first ball, it is convenient to move and adjust the light strip to ensure the installation effect. After the installation is completed, the power cord of the light strip can pass through the second avoidance groove and the third avoidance groove into the wire protection sleeve on the wall, facilitating the wiring operation. When the light strip needs to be removed from the light strip groove, under the action of the first ball, just pull the light strip away from the light strip groove, making the installation and disassembly of the light strip more convenient and fast, and improving the installation efficiency of the background wall.

[0017] For this kind of background wall and its installation method, by setting up a moving mechanism, etc., after the installation of the light strip is completed, first pass the power cord and light harness of the TV through the through hole, and then pass through the wire protection sleeve on the wall through the first avoidance groove, the second avoidance groove and the third avoidance groove, which is convenient for wiring operation. Then, install and fix the decorative panel to the second metal frame. After the installation and fixation are completed, rotate the handwheel. The rotation of the handwheel drives the rotation of the threaded rod, so as to drive the moving push plate to move downward. At this time, the push pin slides upward along the inclined groove. At the same time, it can drive the mounting plate to move along the decorative panel away from the second metal frame through the connecting block, the connecting plate and the L-shaped block, so that the telescopic plate is gradually compressed, and thus the mounting plate can be moved outward along the inner wall of the rectangular frame and can be moved to the outside. At this time, it is convenient to install and fix the TV on the mounting plate, making the installation of the TV more convenient and fast. Moreover, during subsequent maintenance, cleaning and replacement, it is also more convenient and fast. After the TV is installed, reverse the handwheel. At this time, it can drive the push plate to move upward and reset, so that the push pin moves downward along the inclined groove to reset, thereby driving the mounting plate and the TV to gradually move into the rectangular frame to ensure the installation effect.
