According to the tool, a clamping hook structure is designed on the back plate, a small support is omitted, a screw hole is omitted in the rear shell, and a clamping hook is designed, so that the clamping hook of the rear shell and the clamping hook of the back plate are directly matched and fixed, the attractiveness is improved, and the component cost and the production cost are saved.

Description

Technical Field

[0001] The utility model belongs to the technical field of liquid crystal display and accessory installation technology, in particular to a hook fixing tool for a screwless structure. Background Art

[0002] Currently, there are two main methods for securing the back cover of LCD TVs: screws and hooks. Screws create numerous screw holes on the exterior surface, which detracts from the appearance and increases both the cost of screws and production. To improve appearance and save costs, hooks have emerged. However, the current mainstream hook-based method uses a separate small bracket to secure the back cover, eliminating the screw holes and designing hooks in the corresponding locations to secure the back cover and back cover together.

[0003] See Figure 1 As shown, the existing hook-fixed structure includes a bracket 1, a rear shell hook 2 and a back plate 3, all of which are connected by screws 4. Such a connection relationship has an extra small bracket and screws, high component cost, increased assembly time, and high production cost. Summary of the Invention

[0004] Technical solution: In order to solve the above technical problems, the utility model, under the requirements of improving appearance and reducing costs, eliminates the use of brackets and screws by directly designing a hook structure on the back panel, while canceling the screw holes in the back shell and designing hooks, so as to achieve the purpose of both aesthetics and cost saving, and further provides a hook fixing tool for a screw-free structure, specifically including a back panel hook, a back shell hook, a positioning hole, and a positioning column; the back panel hooks are provided in plurality, which are independently and spaced apart and distributed on the back panel side opposite to the back shell, and are a bent plate structure extending from the back panel; the back shell hooks are provided in plurality, which are distributed on the back panel side opposite to the back shell in accordance with the installation position of the back panel hooks; the positioning holes are installed on one side of the back panel hooks for positioning; the positioning columns are installed on one side of the back panel hooks and adaptively correspond to the positioning holes; when the back panel is connected to the back shell, a pair of back panel hooks and the back shell hooks are connected, and a pair of positioning holes and the positioning columns are connected.

[0005] As an improvement, eight pairs of back panel hooks and rear shell hooks are cooperatively installed on the top side and left and right sides where the back panel and rear shell of the LCD TV are installed.

[0006] As an improvement, it also includes reinforcing ribs and two vertical plate structures, which are installed at intervals at the roots of the rear shell hooks.

[0007] Beneficial effect: Compared with the existing conventional ones, the tooling structure proposed by the utility model eliminates the need for a small bracket by designing a hook structure on the back panel, cancels the screw holes on the back shell, and designs a hook. In this way, the back shell hook and the back panel hook are directly matched and fixed, which not only improves the aesthetics, but also saves component costs and production costs.

[0017] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0018] The structure of the present invention is to design a hook structure on the back panel to replace the conventional small bracket and screws; the screw holes are eliminated from the back shell, and hooks are designed at the corresponding positions; thus, installation can be achieved by directly fixing the back shell and the back panel with the hooks.

[0019] See Figure 2As shown, this is a schematic diagram of the hook fixing tooling for the screwless structure of the utility model, including back panel hooks 6 and rear shell hooks 5, which are cooperatively installed on the top side where the back panel and rear shell of the LCD TV are installed, with eight pairs on each side. It replaces the conventional screw installation structure, saves screw costs and labor costs, and also improves the aesthetics after installation.

[0020] See Figure 3-8 As shown, the hook fixing tool for the screwless structure specifically includes a back panel hook 6, a rear shell hook 5, a positioning hole 7, and a positioning column 8; the back panel hook 5 is provided in plurality, which is independently and spaced apart and distributed on the side of the back panel opposite to the rear shell, and is a bent plate structure extending from the back panel; the rear shell hook 5 is provided in plurality, which is distributed on the side of the rear shell opposite to the back panel and the rear shell in accordance with the installation position of the back panel hook 6; the positioning hole 7 is installed on one side of the back panel hook 6 for positioning; the positioning column 8 is installed on one side of the back panel hook 6 and corresponds to the positioning hole 7 in accordance with the positioning hole 7; when the back panel is connected to the rear shell, a pair of back panel hooks 6 and the rear shell hooks 5 are connected, and a pair of positioning holes 7 and the positioning column 8 are connected.

[0021] See Figure 4 As shown, it also includes a reinforcing rib 9, which is provided with two vertical plate structures and is installed at intervals at the root of the rear shell hook. Figure 5 As shown, the backboard hook 6 of the present invention is a bent plate structure extending from the backboard. Due to this design, the hook is formed after the backboard is bent and flanging, which makes operation simpler.

[0022] See Figure 7-8 As shown, the present invention designs positioning holes and positioning columns near the side hooks, which facilitates the positioning of the hooks and makes installation more accurate and quick.

[0023] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
