LED display module with interface protection structure and LED display device

Abstract

The invention discloses an LED display module with an interface protection structure and an LED display device. The LED display module comprises an LED display screen, a protection outer frame is fixedly connected to the right side of the LED display screen, a butt joint groove is formed in the right side of the protection outer frame, a data line butt joint mechanism is connected into the butt joint groove, and a sealing mechanism for sealing the butt joint groove is arranged at an opening of the butt joint groove; through arrangement of an extrusion plate, a movable plate and a sealing door,the problem that a data interface is exposed outside and is easily damaged by external problems to cause failure in normal operation is avoided, and through arrangement of a rotary vertical plate, arotary transverse plate and a waterproof plate, the problem of unstable data transmission caused by rainwater infiltration contact due to severe weather is avoided; and by arranging a ratchet wheel, alimiting block and a pressing plate, the problem that normal work of the LED screen is influenced by looseness between a data interface and a butt joint wire head due to severe weather is avoided.

Description

technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED display module and an LED display device with an interface protection structure. Background technique [0002] The LED display screen is an electronic display screen composed of LED dot matrix. By changing the red and green light beads on and off, the screen display content forms such as text, animation, picture, and video are converted in time, and the component display control is carried out through the modular structure, which is mainly divided into display modules. , control system and power supply system, in which the control system needs the outside world to transmit data through the data interface to control the LED screen. [0003] Among the LED display module invention cases disclosed in the prior art, the Chinese patent with the invention patent application number CN201210376560.2, an LED display module, includes: a casing, a thermal conductor, and op...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide an LED display module to solve the problem that the data interfaces of the current LED screens are all exposed outside in the above-mentioned background technology. In this way, on the one hand, the data interfaces of the LED screens have no protection measures when they are idle, and are easily damaged by sharp objects. Scratch to cause damage, resulting in the failure of the data interface and the failure to work normally. On the other hand, the LED screen is generally installed outdoors. In bad weather, the connection between the data interface and the data cable is easy to loose due to shaking, and rainwater is also easy to seep into the wiring. place, resulting in unstable or malfunctioning data transmission, affecting the normal operation of the LED screen
