Description

Splicing method of LED display screen box bodies with various specifications

Technical Field

The invention belongs to the technical field of splicing LED display screen box bodies, and particularly relates to a splicing method of LED display screen box bodies with various specifications.

Background

The box of current LED display screen is at the concatenation in-process, in order to reach the requirement of box concatenation roughness, all uses the locating pin to accomplish the box location requirement. When the box bodies are spliced up and down, the positioning pins in the box bodies below are inserted into the positioning holes in the box bodies above, and then the splicing is completed. The existing splicing structure can perfectly splice boxes with the same shape and the same size, but can not be connected if the boxes with the same shape and different sizes are spliced. The common application is that the rear connecting sheet is spliced to be flat as much as possible, but the joint of the positioning pin and the positioning hole is reduced, and the mounting process is actually disturbed.

Disclosure of Invention

In order to overcome the defects in the prior art, the invention provides a splicing method of LED display screen box bodies with various specifications.

In order to achieve the purpose, the invention adopts the following technical scheme:

the splicing method of the LED display screen box bodies with different specifications is applied to splicing more than two box bodies with the same style but different lengths, at least two threaded holes are respectively arranged on the upper end surface of each box body at intervals along the length direction of the box body, positioning pins are fixedly connected on the at least two threaded holes in a threaded manner, at least two positioning holes capable of being in splicing fit with the positioning pins are respectively arranged on the upper end surface of each box body at intervals along the length direction of the box body, and at least two detachable wire passing holes are respectively arranged on the upper end surface and the lower end surface of each box body at intervals; the splicing method realizes the arbitrary splicing of the box bodies with the same style but different lengths by moving or adding the positioning pin and selectively detaching the wire passing hole.

By adopting the technical scheme, when the box bodies of the same style and different lengths are spliced, the positioning pins are moved/added), and the wire passing holes are selectively disassembled, so that the box bodies can be spliced at will.
