Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a display screen capable of realizing quantitative adjustment of gaps. Background Art

[0002] Liquid crystal display is a type of flat panel display. It is used for TV and computer screen display. The advantages of this display are low power consumption, small size and low radiation. Liquid crystal display uses a liquid crystal solution in two polarized materials. When current passes through the liquid, the crystals will be rearranged to achieve the purpose of imaging.

[0003] LCD screens are relatively fragile, especially the corners, which are prone to damage. The existing display screen outer protection installation frame structure is relatively simple, which is not convenient for fine-tuning according to different sizes and models, and is prone to leaving gaps, affecting the use effect. Utility Model Content

[0004] The purpose of the utility model is to provide a display screen that can realize quantitative adjustment of the gap, has the advantages of fine-tuning the gap, fitting protection, and ensuring safety in use, and solves the problems in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a display screen that can realize quantitative adjustment of the gap, comprising a side shell and an outer shell, a display screen body is installed in the middle of the outer shell, corner frames are respectively sleeved at the four corners of the outer shell, positioning holes are opened on the upper sides of the corner frames, four corner frames are provided in total, and the four corner frames are connected by transverse frames and longitudinal frames, the side shell is fixed to the outside of the transverse frame and the longitudinal frame, the middle of the inside of the transverse frame and the longitudinal frame are provided with clips, the inner ends of the transverse frame and the longitudinal frame are slidably installed with linkage pieces, and the linkage pieces are rotatably connected to the clips through hinges.

[0006] When using a display screen that realizes quantitative adjustment of the gap in the technical solution, the four corner frames are respectively connected to the four corners of the outer shell of the display screen body. During the connection process, the positioning columns are clamped in the corresponding ones. After the connection is completed, the horizontal frame and the vertical frame are respectively clamped on the four outer edges of the outer shell. At this time, the two ends of the horizontal frame and the vertical frame are respectively fitted with the two end openings of the corner frame. After the connection is completed, the joints are welded by welding equipment, and then the outer side of the side shell is threaded with a tightening screw. The bottom of the tightening screw pushes the clamping piece to move outward to fit the outer shell. The four clamping pieces are adjusted at the same time to clamp and position the outer shell. After assembly, the internal gap is eliminated and the positioning mechanism is perfectly fitted. When the clamping piece is displaced, the hinges connected at both ends pull the linkage piece. The linkage piece made of polyethylene material slides to one side of the clamping piece after being pulled. At this time, the force directions of the two ends of the linkage piece are different, resulting in slight deformation. After the tightening screw is reset, the position of the clamping piece is reset by the deformation of the linkage piece.

[0007] Preferably, positioning columns are fixed at the four corners of the upper end surface of the housing, and the positioning columns are snap-fitted into corresponding positioning holes. The positioning columns are connected to the positioning holes so that the corner frame is sleeved and positioned on the housing.

[0008] Preferably, the corner frame is designed in the shape of a right triangle, and the corner frame is adapted to the corners of the housing. The shape of the corner frame is designed to fit the corners of the housing.

[0009] Preferably, two transverse frames and two longitudinal frames are provided, and the transverse frames and the longitudinal frames are respectively sleeved on the four outer edges of the shell. The transverse frames and the longitudinal frames are attached to the shell to form external corner protection.

[0010] Preferably, a groove is provided in the middle of the outer side of the side shell, and a tightening screw is installed through the inner thread of the groove. The tightening screw is received in the groove to achieve hidden installation.

[0011] Preferably, the lower end of the tightening screw is connected to the inner side of the corresponding clamping piece. The clamping piece is moved by the lifting and lowering of the thread of the tightening screw.

[0012] Preferably, both ends of the transverse frame and the longitudinal frame are fixed with limit strips, and a limit slot is provided at the rear side of the end of the linkage piece away from the clamping piece, and the limit strip is butted with the limit slot. The limit strip cooperates with the limit slot to allow the linkage piece to move, and the polyethylene material of the linkage piece itself can be slightly deformed.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: during installation, the four corner frames are respectively connected to the four corners of the outer shell of the display screen body. During the connection process, the positioning columns are clamped in the corresponding ones. After the connection is completed, the horizontal frame and the vertical frame are respectively clamped on the four outer edges of the outer shell. At this time, the two ends of the horizontal frame and the vertical frame are respectively fitted with the two end openings of the corner frames. After the connection is completed, the joints are welded by welding equipment, and then the outer side of the side shell is threaded with a tightening screw, and the bottom of the tightening screw pushes the clip to make the clip move outward to fit the outer shell. The four clips are adjusted at the same time to clamp and position the outer shell. After assembly, the internal gap is eliminated and the positioning mechanism fits perfectly. When the clip is displaced, the hinges connected at both ends pull the linkage piece, and the linkage piece made of polyethylene material slides to one side of the clip after being pulled. At this time, the force directions of the two ends of the linkage piece are different, resulting in slight deformation. After the tightening screw is reset, the position of the clip is reset by the deformation of the linkage piece. The device has a simple structure and is easy to operate. The gap is filled by the adjustable clip, and the outer shell of the display screen body is effectively positioned to ensure its fixing quality. BRIEF DESCRIPTION OF THE DRAWINGS
