Description
Technical Field
The invention relates to the technical field of LED screens, in particular to an outdoor self-locking LED display screen.
Background
Along with the improvement of the outdoor LED display screen process, the technology is mature day by day and the cost is reduced, the application field is wider and wider, but the thick and heavy installation mode of the conventional LED display screen also limits the application of some occasions, such as urban streets, doorheads and outer walls of shopping malls, lamp box advertisements with smaller installation positions are replaced, the installation positions of the places are relatively smaller, the visual range is smaller, and the population of the places is relatively dense, so the installation thickness of the screen body applied to the positions is as thin as possible, the construction amount is as small as possible, the time is short, the pixel density of the screen body is high, the visible viewing distance is small, the installation and maintenance are rapid and convenient, and the like. Due to the limitation of installation thickness, the installation of the screen body needs to be installed and maintained from the display surface of the screen body.
The front maintenance display screen is installed in the market, the light and thin installation thickness of the screen body can be achieved, however, due to the designed locking structure and the installation mode, the pixel density of the screen body is limited to be not high, the screen body is limited to the LED display screen with large pixel distance, and the installation and maintenance time is long. For example, when the module is mounted and dismounted, the rotary locking devices are mounted on two sides or four corners of the display module, the display module is inserted from the front of the display module by using an inner hexagonal screwdriver during mounting, the clamping piece is driven to rotate by the rotating device, the module is clamped to the inner side of the box body and locked, and the module is mounted on the structural box body. When the display module is maintained, the hexagonal screwdriver is inserted from the front of the display module, and the clamping piece is driven to be loosened from the box body by the reverse rotation, so that the module is taken out. When the screen body is installed, the four-corner modules of the box body are taken out, the four-corner installation structure of the box body is exposed, the box body is fixed on the steel frame through screws, and then the four-corner modules are installed on the box body.
This kind of mounting means need reserve certain space aperture on the module display surface and supply the interior hexagonal screwdriver to insert, and this hole still need keep apart the PCB waterproof, in addition because rotary device and the clamping piece of being connected with the box be the direct-connected mode, need have certain moment of torsion and can drive the clamping piece, so the external diameter of interior hexagonal screw can not be too little. In order to prevent water and influence display, holes reserved on the module surface need to be arranged among four LEDs arranged in a matrix, so that the arrangement of the LEDs is displayed, and a high-density outdoor LED display screen cannot be realized. In addition, tools are needed when the display screen module is installed, so that the installation speed and the installation time are influenced. The screen body installation efficiency is not high.
