Radian lock

Technical Field

The utility model belongs to the technical field of the display screen technique and specifically relates to an radian lock.

Background

When the current display screen is spliced, a radian mechanism is generally adopted to realize the effect of an arc screen.

The first method is to adopt an arc lock: mainly adopt radian motion (hasp) to link together two boxes (assemble the unit), thereby form a concatenation angle and form the arc display screen, mainly be applied to and lease the display screen. The disadvantages are as follows: the radian lock still needs stroke angle function under the condition of guaranteeing that the box aligns, can lead to the structure of radian lock huge, complicated to influence and assemble speed and assemble the precision. As the Chinese utility model patent: 202022815169.6, an arc shaped lock catch. The structure is complex, the installation process is relatively troublesome, and the assembling speed can be influenced.

The second method is to use an angle mounting plate: the two box bodies (assembly units) are connected together by the mounting plate at an angle to form a splicing angle, so that the arc-shaped display screen is formed, and the arc-shaped display screen is mainly applied to fixedly mounting the display screen. The disadvantages are as follows: because the method generally adopts screw installation, and can not adjust the angle, the angle can only be changed by changing the angle plate, tools are needed during assembly, the speed is very low, and the high-altitude operation has discrete components, has potential safety hazards, and is not suitable for rental occasions.

Therefore, a radian lock which is used for assembling a display screen box body and has a simple structure and a large angle adjusting range is needed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above-mentioned technique not enough and provide an radian lock, the structure is comparatively simple, can assemble the angle to the display screen box and adjust, and the control range is great.

The utility model discloses an arc lock, including axis of rotation, first mount pad, second mount pad, first rotation piece and second rotation piece, all be provided with the shaft hole on first rotation piece and second rotation piece, first rotation piece, second rotation piece pass through the shaft hole setting on the axis of rotation, rotate between first rotation piece and the axis of rotation and be connected, fixed connection between second rotation piece and the axis of rotation, through the round pin hub rotation connection between one end of first rotation piece and the first mount pad, the other end of first rotation piece passes through the first connecting piece of round pin hub connection, the first connecting piece rotates with the second mount pad through the round pin axle and is connected, rotates through the round pin hub connection between one end of second rotation piece and the second mount pad and is connected, and the other end of second rotation piece passes through the second connecting piece of round pin hub connection, and the second connecting piece rotates with the first mount pad through the round pin axle and is connected; the first rotating member is provided with a guide hole, the guide hole extends into the shaft hole, positioning columns are arranged in the guide hole, and a plurality of positioning holes are arranged on the circumference of the rotating shaft corresponding to the guide hole at intervals.
