Description

Technical Field

[0001] This utility model relates to the field of television positioning technology, specifically to a television bracket. Background Technology

[0002] With technological advancements, old-fashioned CRT televisions have gradually been replaced by LCD televisions. LCD televisions are larger and thinner, saving installation space. Typically, home LCD televisions are mounted on the wall using fixed brackets, meaning their position is fixed and cannot be adjusted, resulting in a poor user experience.

[0003] For example, Chinese utility model patent ZL202221085620.6 (publication number CN217329324U), entitled "A Six-Section Arm Multi-Angle Adjustable TV Stand," discloses such a TV stand. This TV stand includes a mounting back plate, an upper rotating arm, a lower rotating arm, a front rotating arm, a connecting plate, and a front support plate. A first bushing is provided at the first end of the front rotating arm, and a connecting shaft is provided inside the first bushing. Second bushings are provided at the ends of the upper and lower rotating arms, and the second bushings are fitted into the corresponding connecting shafts. The TV, mounted on the front support plate, can be adjusted to multiple angles within the same horizontal plane. However, during TV viewing, users adopt different sitting postures, resulting in different tilt angle requirements for the TV screen. The tilt angle of the TV needs to be adjusted accordingly to avoid reflections and image distortion. The aforementioned TV stand cannot meet the tilt angle adjustment requirements.

[0004] Therefore, further improvements are needed to the structure of the TV stand. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a TV bracket that can simultaneously satisfy the adjustment of horizontal and tilt angles, in view of the above-mentioned existing technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: the TV bracket includes:

[0007] Wall panels are used to fix the wall surface;

[0008] The rear support arm is located on the front side of the wall panel and is rotatably connected to the wall panel;

[0009] The front support arm is located above and in front of the rear support arm and is rotatably connected to the rear support arm.

[0010] A mounting plate is provided on the front side of the front support arm and can be used to fix the TV in place.

[0011] Its characteristic is that it also includes:
