Title:
LED DISPLAY SCREEN CASE LATCH STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2019/047416
Kind Code:
A1
Abstract:
Provided is an LED display screen case latch structure, comprising: adjusting blocks (2), angle blocks (3) and curved guide rails (14). All the adjusting blocks (2), the angle blocks (3) and the cured guide rails (14) are arranged on a case body (1). The adjusting blocks (2) are connected with the angle blocks (3) by means of the curved guide rails (14). When the adjusting blocks (2) are in linear motion, the angle blocks (3) are driven to rotate by means of the curved guide rails (14). The case body (1) is also provided with latch locking structures corresponding to the angle blocks (3). The angle blocks (3) on one case body (1) cooperate with latch locking structures (4) of another case body to adjust the angle of the two case bodies. Linear motion of the adjusting blocks (2) is converted into rotational motion of the angle blocks (3) by means of the curved guide rails (14) so as to realize angle adjustment, and angle splicing precision is improved. The LED display screen case latch structure is simple in structure and convenient to operate, and has no need for machining so that the cost is greatly reduced.
