Arc splicing structure

Abstract

The invention discloses an arc splicing structure. The arc splicing structure comprises a first connecting unit, a second connecting unit and a lock seat, wherein an adjustment device is arranged on the second connecting unit and comprises an adjustment rod, a sliding seat and a sliding piece, the sliding seat is fixedly sleeved on the adjustment rod, the sliding piece is slideably arranged on the sliding seat, one end of the lock seat is connected on the sliding piece, the other end is connected with the first connecting unit, the adjustment rod is used for driving one end of the lock seat to vertically move along the adjustment rod and furthermore the connecting angle between the first connecting unit and the second connecting unit is changed. The arc splicing structure is simple and compact, and compared with the synchronized adjustment of two display screen modules in the prior art, the angle of the first connecting unit relative to the second connecting unit which is adjusted by the adjustment device is high in adjustment precision, and has no clearance and is flat.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an arc splicing structure. Background technique [0002] Based on the rapid development of the LED display industry, more and more new types of products are coming to the market. Most of the current curved screens use fixed-angle connecting blocks, or use the principle of curved slide rails, or use rolling slide rail technology to realize the screen. connection to the screen. [0003] Patent No. 201310355370.2 discloses an angle-adjustable LED display connection device, which includes an adjustment rod, a connecting rod, a connection block and an adjustment slider. In this structure, since the adjustment rod can move up or down, The adjustment slider connected with the adjustment rod can slide relatively along the chute of the connection block, and is linked with the connection block through the connecting rod, so that the connection block swings around the center of...

[0003] Patent No. 201310355370.2 discloses an angle-adjustable LED display connection device, which includes an adjustment rod, a connecting rod, a connection block and an adjustment slider. In this structure, since the adjustment rod can move up or down, The adjustment slider connected with the adjustment rod can slide relatively along the chute of the connection block, and is linked with the connection block through the connecting rod, so that the connection block swings around the center of the adjustment slider, so that the clamping between the spliced ​​display screens The angle changes to change the radian of the display screen. In this structure, since the two connected LED displays change the angle at the same time during adjustment, it is difficult to solve the problems of adjustment accuracy and adjustment flatness.
