Description

Technical Field

[0001] The utility model relates to the technical field of a fixing method of a PCB board of a liquid crystal panel on a backlight module, and in particular to an umbrella-shaped elastic buckle structure compatible with PCB boards of liquid crystal panels with different board widths. Background Art

[0002] In the prior art, there are two main ways to fix the PCB board of the LCD panel on the backplane:

[0003] 1. The use of foam + double-sided tape for fixing is easily affected by ambient temperature and operator negligence, resulting in the risk of the PCB board of the LCD panel falling off;

[0004] 2. Plastic clips are used for fixing. Although this fixing method does not require double-sided tape, this structure is not compatible with PCB boards of different board widths. PCB boards of LCD panels of different widths correspond to one plastic clip, resulting in a large variety of developed materials and poor sharing, which can easily lead to waste of costs such as obsolete materials. Summary of the invention

[0005] The utility model aims to overcome the deficiencies of the prior art and provide an umbrella-shaped elastic buckle structure compatible with PCB boards of liquid crystal panels with different board widths.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An umbrella-shaped elastic snap-in structure compatible with liquid crystal panel PCB boards of different board widths comprises a board body, at least one snap-in structure is arranged on the back of the board body, and the snap-in structure is used to snap-in and fix in a positioning hole of the back board; a retaining wall is arranged at the lower end of the board body, and two elastic umbrella rib arms are arranged downwardly to both sides respectively at the upper end of the board body, and hooks are arranged at the free ends of the two umbrella rib arms respectively.

[0008] Furthermore, the umbrella-shaped elastic buckle structure is integrally injection-molded using a polymer material.

[0009] Furthermore, the snap-fit ​​structure is composed of two small snap buckles arranged at intervals, and the free ends of the small snap buckles are large ends.

[0010] The utility model adopts the above technical solution. Since the two umbrella arms are elastic (can be expanded and contracted), during installation, the two umbrella arms can be expanded outward according to the width of the liquid crystal panel PCB board. After the PCB board is inserted into the retaining wall below, the two umbrella arms automatically rebound and fasten the PCB board, thereby adapting to the fixation of PCB boards of different widths. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0012] Figure 1 It is a schematic diagram of the umbrella-shaped elastic buckle structure of the utility model;

[0013] Figure 2 A schematic diagram of the umbrella-shaped elastic buckle structure of the utility model from another perspective;

[0014] Figure 3 It is a schematic diagram of an umbrella-shaped elastic buckle structure clamping and fixing a liquid crystal panel PCB board. DETAILED DESCRIPTION

[0015] like Figure 1-3 As shown, the utility model is an umbrella-shaped elastic buckle structure compatible with LCD panel PCB boards of different board widths. The overall structure utilizes the strength and toughness of polymer materials and is integrally injection-molded into an elastic buckle structure.

[0016] The umbrella-shaped elastic snap-on structure includes a plate body 1, and at least one snap-on structure 2 is provided on the back of the plate body 1, and the snap-on structure 2 is used to snap-on and fix in the positioning hole of the back plate. Among them, the snap-on structure 2 is composed of two small snaps arranged at intervals, the free end of the small snap is the large end, and the connection end of the small snap and the plate body 1 is the small end. When the large ends of the two small snaps are inserted into the positioning holes of the back plate, they are first compressed, and after the insertion, the two small snaps return to their positions, and the large ends of the small snaps play a limiting role, thereby fixing the entire umbrella-shaped elastic snap-on structure on the back plate. When the umbrella-shaped elastic snap-on structure is to be disassembled, pinch the large ends of the two small snaps and then pull out the umbrella-shaped elastic snap-on structure.

[0017] A retaining wall 3 is provided at the lower end of the plate body 1, and two elastic umbrella arms 4 (capable of being expanded and contracted) are respectively extended downward to both sides at the upper end of the plate body 1, and hooks 5 are respectively provided at the free ends of the two umbrella arms 4, wherein the two umbrella arms 4 are symmetrical structures.

[0018] The use of the utility model:

[0019] 1. Insert the clamping structure 2 on the back of the board body 1 into the corresponding positioning hole of the back plate;

[0020] 2. Insert the PCB board 6 of the LCD panel into the hooks 5 of the two umbrella arms 4 (open the umbrella arms 4);

[0021] 3. The PCB board 6 of the liquid crystal panel is inserted into the lower retaining wall 3, and the two umbrella arms 4 rebound (contract), and the hooks 5 at the lower ends of the two umbrella arms 4 clamp and fix the PCB board of the liquid crystal panel.

[0022] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
