LED display system, gap adjusting device for fixing and assembling screen bodies and adjusting method

Abstract

The invention belongs to the technical field of assembly and aims to provide a gap adjusting device for fixing and assembling screen bodies. The gap adjusting device comprises a first adjusting component, a second adjusting component and a connecting plate which is used for connecting a first screen body unit with a second screen body unit; the invention also aims to provide an LED display system and an adjusting method of the gap adjusting device. According to the invention, a first adjusting cushion block and a second adjusting cushion block are respectively arranged on the back surfaces of two adjacent screen body units, and movable blocks respectively corresponding to the first adjusting cushion block and the second adjusting cushion block can move in respective slide ways with the same inclination, so that the front sides of the two adjacent LED screen body units are flush with each other through stepless fine adjustment; through the rotation of a first eccentric shaft and / or a second eccentric shaft, the distance between the matching center of each eccentric shaft and the connecting plate, and that of the respective opposite eccentric shaft and the connecting plate can be adjusted, so that gaps between the two adjacent screen body units in the vertical and horizontal directions can be subjected to stepless fine adjustment, and further, the requirement for small space assembly is satisfied and the display effect of the high density LED display system is improved.

Description

Technical field [0001] The invention belongs to the technical field of assembling, and relates to a gap adjustment device, in particular to an LED display system, a gap adjustment device for fixed and assembled screens, and an adjustment method of the gap adjustment device. Background technique [0002] LED display screens are generally assembled by a combination of several independent LED display units, and LED display units generally adopt a box structure or a unit board structure. Therefore, the fixed assembly of the LED display screen is mainly reflected in the box of each LED display unit. The connection between the body or the connection between the unit boards. Obviously, in order to ensure the image display quality of the LED display screen assembled by such a combination, it is an important technology to control the surface flatness of the entire display screen within a certain range. [0003] In the prior art, the connection between the fixed and assembled boxes of the L...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the technical problem that the existing assembly method cannot meet the assembly requirements and seriously affect the display effect when the screen body units are adjusted in a small distance range during the fixed assembly process of the screen body. The eccentric shaft on the component, and the push rod or gear shaft of one of the two adjustment components is selected to push the corresponding movable block to move, so as to realize the stepless fine-tuning of the fit gap in all directions during the screen body fixing and assembling process.
