LED Display screen box lock structure

Abstract

The invention belongs to the technical field of displays and discloses an LED display screen box lock structure, comprising adjusting blocks, angle blocks and curved guide rails; all the adjusting blocks, the angle blocks and the cured guide rails are arranged on a box body; the adjusting blocks are connected with the angle blocks through the curved guide rails; when the adjusting blocks are in linear motion, the angle blocks are driven to rotate through the curved guide rails; the box body is also provided with lock locking structures corresponding to the angle blocks; the angle blocks on one box body cooperate with lock locking structures of another box body to adjust the angle of the two box bodies; linear motion of the adjusting blocks is converted into rotational motion of the angle blocks through the curved guide rails so as to arrive at angle adjustment, and angle splicing precision is improved; the LED display screen box lock structure is simple in structure and convenient to operate, and has no need for machining so that the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a locking structure of an LED display box. Background technique [0002] At present, arc-shaped splicing screens mostly use arc-shaped guide rails to achieve arc-shaped splicing, and the accuracy error of the fit gap of the arc-shaped guide rails will be magnified dozens of times in the tangential direction of the arc, making it difficult to ensure the splicing accuracy of the display screen. The force direction is consistent with the adjustment direction, so the existing arc guide rail must have a locking device to ensure that the adjusted angle is fixed, and its structure is relatively complicated, and the operation is inconvenient. [0003] In the prior art, angle pads are also used to solve the problem of precision error, but one angle pad can only adjust one angle, and different angle pads must be replaced to adjust different angles, which increases the cost and is inconven...

[0003] In the prior art, angle pads are also used to solve the problem of precision error, but one angle pad can only adjust one angle, and different angle pads must be replaced to adjust different angles, which increases the cost and is inconvenient to use
