Storage rack for outdoor LED display screen

Abstract

The invention provides a storage rack for an outdoor LED display screen, and relates to the field of LED display screens. The storage rack for the outdoor LED display screen comprises a fixing frame, a containing groove is formed in the fixing frame, a wire passing groove is formed in the containing groove, a bearing frame is fixedly connected to the top end of the fixing frame, and fixing frames are inserted into the positions, located at the upper end and the lower end of the containing groove, of the interior of the fixing frame. When the storage rack for the outdoor LED display screen is used, a servo motor drives a worm to rotate, the worm drives a worm gear to rotate, the worm gear drives a driving wheel to rotate, the driving wheel drives a driven wheel to rotate under the action of a first connecting frame, the first connecting frame rotates under the action of the driving wheel and the driven wheel, and meanwhile a connecting frame rotates; the first connecting frame drives the second connecting frame to rotate through the fixing rod, the second connecting frame drives the swing frame to rotate through the first rotating wheel and the second rotating wheel, at the moment, the swing frame, the connecting frame and the fixing frame are located on the same horizontal line, and storage is convenient.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to a storage rack for outdoor LED display screens. Background technique [0002] LED display: LED is light emitting diode, the English abbreviation of light emitting diode, referred to as LED, it is a display method by controlling semiconductor light emitting diodes, its general appearance is composed of many usually red light emitting diodes, relying on lights It is a display screen used to display characters, graphics, images, animations, market quotations, videos, video signals and other information. [0003] In order to realize the splicing of the LED display screen, the support back frame is generally built on the site. At present, the mainstream installation of the steel structure of the LED display screen is the method of welding aluminum profiles. The steel structure occupies a large space, is expensive, and is complicated to operate. It will cause environmental...

Problems solved by technology

[0003] In order to realize the splicing of the LED display screen, the support frame is generally built on the site first. At present, the mainstream installation of the LED display screen is still to use the welding aluminum profile. It will cause environmental pollution. When the existing LED display screen is assembled, the staff needs to hold the LED display screen and fix the four corners of the screen with bolts. The installation is difficult and the labor cost is high.
