Description

Technical Field

[0001] The utility model relates to the technical field of TV frames, in particular to a light leakage prevention liquid crystal TV frame. Background Technique

[0002] A liquid crystal TV is generally used to receive analog TV programs broadcast by a TV station, and the received analog TV programs are processed and then the images are reproduced. A complete TV generally includes several major components such as a screen, a main board, a power supply, wires, fasteners and a cabinet. Among them, the cabinet is an important component for carrying the other major components. The cabinet needs to be reasonably designed in terms of structure considering various factors such as space, heat dissipation and market popularity. Nowadays, in order to reduce the production difficulty and improve the assembly efficiency of the TV at the same time, the cabinet is generally split into a front frame, a middle frame, a frame and a rear shell according to the actual situation and injection molded separately. Therefore, corresponding and matching connection structures are provided on the cabinet components such as the front frame, the middle frame, the frame and the rear shell.

[0003] The stability of the existing snap connection part between the frame and the rear shell is generally poor, and the snap part is prone to shaking. When the shaking degree is too large, the snap part is prone to damage. Moreover, the existing frame is generally used to carry a backlight module and a liquid crystal screen, and there will inevitably be a fitting gap in the snap connection method, which will easily cause light leakage at the snap connection position between the frame and the rear shell. In addition, the mechanical strength of the existing frame is low, which causes the frame to be easily damaged during use and also shortens the overall service life of the frame.
