Flange type angle lock device and display screen module

Abstract

The invention provides a flange type angle lock device. The flange type angle lock device comprises a lock cylinder assembly and a quick lock assembly which is matched and locked with the lock cylinder assembly; the lock cylinder assembly comprises an angle turning core, a turning core cover plate fixedly connected with the angle turning core, an angle adjusting knob fixedly connected with the turning core cover plate, and a compression locking device installed in the angle adjusting knob, wherein the turning core cover plate is located between the angle turning core and the angle adjusting knob; the angle adjusting knob is located between the turning core cover plate and the compression locking device; and the lock cylinder assembly further comprises a positioning and mounting assembly connected with the angle turning core. By using the technical scheme provided by the invention, not only the rapid splicing and locking of a display screen module is realized, but no tools are needed inthe entire splicing process, so that the splicing process is simplified while the splicing precision is improved, and the cost of the product is also saved.

Description

technical field [0001] The invention relates to the technical field of locking connection, in particular to a technical field for splicing and locking of LED display modules. Background technique [0002] The LED display industry is developing rapidly, and the application fields are constantly expanding. The development trend of this industry is constantly approaching large screens and super large screens, and the traditional flat screens can no longer meet the growing demand of the market. More and more curved screens or multi-shaped screens The development of the screen is put on the agenda. [0003] However, large-size display screens and multi-model display screens are not easy to realize in terms of technology and the transportation efficiency in product transportation is not high, which has always been a pain point in the industry. The current popular technology is to divide the large-size display into multiple small-size display modules, manufacture the small-size mo...

Problems solved by technology

[0003] However, large-size display screens and multi-model display screens are difficult to realize in terms of technology and the transportation efficiency in product transportation is not high. It has always been a pain point in the industry.

The current popular technology is to divide the large-size display into multiple small-size display modules, manufacture the small-size modules in the factory with the existing technology, and then transport the small-size modules to the installation site according to the large-size The design of the display screen requires splicing, which solves the problems that the large-size display screen is not easy to realize in technology and the transportation efficiency is low

[0004] In industrial practice, spliced ​​large-size display screens need to be tightly and securely connected and locked each component module. For flat-screen display screens, there are many locking methods in the prior art that can meet the design and installation requirements. If the screen is a curved surface (or curved surface) or a multi-shaped surface, it is necessary to design a special locking device according to the design curvature or shape of the display screen, which increases the design difficulty of large-size multi-shaped display screens and causes product parts Versatility Difficulties

[0005] Although there are universal multi-angle locking devices on the market, it still cannot eliminate the relatively large assembly gap and ensure the high-precision assembly requirements required by the design.
