Description

Liquid crystal support structure convenient for checking liquid crystal display pin continuous welding Technical Field The utility model relates to the technical field of liquid crystal display equipment, in particular to a liquid crystal bracket structure convenient for checking the pin connection welding of a liquid crystal display. Background In the prior art, when a liquid crystal screen is assembled to a circuit board through a bracket and welded, the technical defects that 1) the tin-plating time is different in the welding process, the adjacent pins are easy to generate continuous welding, the continuous welding phenomenon is difficult to directly observe in appearance, hidden quality hazards exist, 2) the traditional liquid crystal bracket is flatly mounted on the circuit board, high-temperature soldering tin is easy to enable the back of the bracket to be scalded and deformed during welding, the continuous welding faults are further covered after deformation, and the product function is poor, 3) the traditional bracket structure cannot visually check the tin-plating state of the circuit board after welding, and the efficiency is low and the liquid crystal bracket is damaged by means of additional tools or disassembly inspection. Therefore, a liquid crystal bracket structure convenient for inspecting the pin connection welding of the liquid crystal display is provided. Disclosure of Invention The utility model aims to solve the problems and provides a liquid crystal bracket structure which is convenient for checking the pin connection welding of a liquid crystal display. In order to achieve the purpose, the utility model provides a liquid crystal support structure convenient for inspecting the pin connection welding of a liquid crystal display, which comprises a liquid crystal support body and is characterized in that one side of the liquid crystal support body connected with a circuit board is provided with a step structure, a reserved space for inspecting the pin connection welding of the liquid crystal display is formed between the liquid crystal support body and the circuit board in the step structure, and a through hole which is used for the pin of the liquid crystal display to pass through and corresponds to the welding hole position on the circuit board is formed in the liquid crystal support body. Preferably, the step structure is arranged at a position corresponding to the through hole on the liquid crystal bracket body. Preferably, the top of the liquid crystal support body is provided with an installation groove for embedding and installing a liquid crystal screen, and both sides of the liquid crystal support body are provided with a buckle connected with the circuit board in a clamping way and a guide rod used for positioning.
