Description

Technical Field

[0001] This utility model relates to the field of display device technology, and specifically to a splicing display screen. Background Technology

[0002] Video wall displays are combinations of multiple display units that enable large-size, high-resolution image or video displays. They are widely used in commercial advertising, information dissemination, security monitoring and other fields, and are characterized by high flexibility, high scalability and uniform display effect.

[0003] Traditional video wall systems use rigid fixed frames or complex snap-fit ​​designs, which are time-consuming to install and have low alignment accuracy, making it easy for adjacent display units to misalign or have uneven gaps. Secondly, during the installation process, the frame may bend or the display units may have different thicknesses, which changes the flatness and affects the consistency of the display. In addition, there are no connecting parts at the splicing gaps between display units, and they are mostly directly pressed together, which makes it easy for heat to accumulate here, thus affecting the lifespan of internal components. Utility Model Content

[0004] This utility model provides a modular splicing display screen, which solves the problems of complex splicing structure, inability to adjust flatness, and poor heat dissipation of existing screens by optimizing the connection structure.

The connecting frame adopts a modular splicing structure, including a positioning frame, a connecting frame, and a plug-in plate. The positioning frame is fixedly connected to the back of the display unit, and the two ends of the connecting frame are plugged and fixed to the positioning frame on the back of the adjacent display unit. The plug-in plate is plugged between adjacent display units and plugged into the middle of the connecting frame. The positioning frame is a square groove structure, and each of the four sides of the positioning frame is provided with elastic buckles, which are plugged and fixed to the two ends of the connecting frame. The connecting frame is a U-shaped structure, and the middle of the connecting frame is provided with multiple elongated fixing holes.

[0006] As a preferred embodiment of this utility model, the back of the display unit is fixedly connected to the positioning frame by multiple bolts, and an adjustment shim is provided between the display unit and the positioning frame to adjust the flatness of the display unit, and the bolts pass through the adjustment shim and are fixed to the display unit.

[0007] As a preferred technical solution of this utility model, the positioning frame is provided with a corresponding positioning port at the connecting frame, and the inner side of the positioning port is provided with a limiting plate that abuts against the outer side of the positioning frame, and the adjacent limiting plates are spliced ​​together to form an L-shaped structure.

[0008] As a preferred technical solution of this utility model, the two sides of the connecting frame are provided with a plurality of equidistant positioning holes at the elastic buckle.

[0009] As a preferred technical solution of this utility model, the elastic buckle includes two positioning plates extending from the positioning frame, a positioning pin passing through the two positioning plates, and a compression spring located between the two positioning plates. The positioning pin is slidably connected to the positioning plates, and a force-bearing plate is provided between the positioning pin and the positioning plates. The compression spring is sleeved on the outside of the positioning pin, and one end abuts against the force-bearing plate.

[0010] As a preferred technical solution of this utility model, an L-shaped auxiliary pin is provided on one side of the positioning pin, and the front end of the auxiliary pin is flush with the front end of the positioning pin, which is used to assist in positioning the connecting frame and prevent the connecting frame from rotating.

[0011] As a preferred technical solution of this utility model, the connecting frame is provided with a slot in the middle for insertion into the plug-in plate, and the plug-in plate is provided with a corresponding slot. An expansion gap of 0.1-0.3mm is formed between adjacent display units, and a thermally conductive silicone strip is provided on the plug-in plate to fill the expansion gap.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] This splicing display screen reduces splicing steps through modular design. It achieves quick locking by inserting the positioning pin in the elastic buckle with the connecting frame, which can save a lot of time and manpower.

[0014] This splicing display screen compensates for screen errors by adjusting the number or thickness of the shims, preventing the screens from not being on the same plane during installation and improving visual consistency.

[0015] This splicing display screen fills the gap between adjacent display units by setting up a connector plate between them, which prevents collisions. At the same time, it uses thermally conductive silicone strips embedded in the expansion gap to balance heat dissipation and structural sealing. Attached Figure Description
