Technical Field

The invention relates to the technical field of display screen splicing, in particular to a positioning connection locking device and a display screen.

Background

The display screen is a display tool for displaying electronic files on the screen through a specific transmission device. Some of large-scale LED display screens need to be spliced together through connecting tools, and the splicing of display screens means splicing more than two display screens into a whole block to reach the purpose of reinforcing visual effect, reduction space occupies. The small-spacing display screen is formed by carrying out plane assembly on a plurality of box bodies through a back assembly connecting mechanism.

Because the pixels of the small-distance display screen are small, the small-distance display screen is formed by seamlessly splicing boxes with different quantities. The requirement on the size precision between the boxes is very high, and a small size error can cause the inconsistency between the pixel interval of the splicing part between the boxes and the interval inside the boxes, so that the display effect of the whole display screen is influenced. In the assembling process, due to the fact that precision errors exist in box body machining, front and back dislocation can occur between partial box bodies in the assembling thickness direction, and the display effect of the whole screen is affected.

The existing box body assembling and connecting mechanism is characterized in that the connecting mechanism is arranged on a back support, and then an operator holds the box body and then positions and connects the box body with the connecting mechanism, so that the operator is difficult to accurately position and assemble in a short time during assembling, and needs large force to operate at the same time, thereby causing low efficiency; the box body assembling and connecting mechanism is arranged on the back of the box body, so that non-artificial loosening is easily caused, and certain potential safety hazards exist.

The small-space display screen is installed with two modes by current hoisting: one is realized by directly hoisting the whole screen by a hoisting mechanism; and the other is that the back of the whole screen is connected with a back support to form a whole, and then the whole is hoisted. Both of these approaches suffer from the same drawback: the connection between box and the box uses the connection piece at box back installation, and the atress part of every box also is this connection piece during hoist and mount, because the connection piece is at the box back, does not lie in the focus perpendicular of the whole screen body, when leading to hoist and mount like this, because box self weight, can produce open phenomenon between the front of box and back to influence whole screen display effect. Meanwhile, the connecting sheet is not arranged on the vertical plane of the center of gravity of the hung screen body, so that the whole screen can tilt forwards or backwards due to the gravity relation, the connecting sheets at different height positions are not stressed uniformly, and potential safety hazards exist.
