Description

Technical Field

[0001] This utility model relates to the field of display device installation technology, and in particular to a fixing structure for a bus LED display screen. Background Technology

[0002] With the development of smart cities and public transportation informatization, LED displays are widely used in bus stops, rail transit platforms and other places to publish real-time vehicle arrival information, advertising and other content.

[0003] However, in the existing technology, most bus displays are set on the front, rear and sides of the vehicle body for quick identification of people in the surrounding area. However, most of the bus displays are installed using a fixed structure, which makes disassembly and replacement during maintenance complicated. At the same time, due to the variety of sizes of some bus displays and the single function of some bracket structures, there are certain limitations in the installation of bus displays. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art: most of the bus display screens are installed using a fixed structure, which makes disassembly and replacement during maintenance complicated. At the same time, due to the variety of sizes of some bus display screens and the single function of some bracket structures, there are certain limitations in the installation of bus display screens.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a fixing structure for a bus LED display screen, comprising: a mounting base; multiple mounting slots disposed at the four corners of the top surface of the mounting base; and further comprising:

[0006] A protective structure is disposed on the surface of the mounting base, the protective structure comprising:

[0007] Multiple mounting rods are movably embedded inside the mounting groove, and the mounting rods slide up and down inside the mounting groove. The surfaces of the multiple mounting rods are provided with round holes, and the top surfaces of the multiple mounting rods are connected by a protective cover.

[0008] A positioning structure is disposed on the surface of the mounting base, the positioning structure further comprising:

[0009] Two sets of springs are fixedly mounted on the surface at symmetrical locations on the mounting base.

[0010] Preferably, the positioning structure further includes: positioning pins fixedly disposed on one end surface of the two sets of springs, and one end of the two sets of positioning pins being embedded in the interior of the circular hole.

[0011] The technical effect of adopting the above-mentioned further solution is that the positioning pins on a pair of surfaces are fixed by the spring, which makes it convenient for the positioning pins to be embedded in the inside of the round hole for positioning.

[0012] Preferably, a guide rod is fixedly provided on the inner wall of the mounting base, and a stepper motor is provided on the outer surface of the mounting base through the frame.

[0013] The technical effect of adopting the above-mentioned further solution is that the bidirectional lead screw on the inner wall is fixed by the mounting seat.

[0014] Preferably, the output end of the stepper motor is fixedly provided with a bidirectional lead screw, and a mounting bracket is threaded onto the symmetrical part of the outer surface of the bidirectional lead screw.

[0015] The technical effect of adopting the above-mentioned further solution is that when the stepper motor is working, the bidirectional lead screw on the output end surface rotates, and at the same time, the bidirectional lead screw drives the mounting bracket on the outer surface to move in a centered manner.

[0016] Preferably, the two mounting brackets are slidably fitted onto the surface of the guide rod, and T-slots are formed on the surfaces of the two mounting brackets facing each other.

[0017] The technical effect of adopting the above-mentioned further solution is that the guide rod provides a limiting function for the mounting bracket, and the T-slot on the surface of the mounting bracket facilitates the installation of parts.

[0018] Preferably, mounting blocks are slidably embedded inside the two T-slots, and positioning holes are provided at symmetrical locations on the surfaces of the two mounting blocks.

[0019] The technical advantage of adopting the above-mentioned further solution is that the mounting block is limited and installed by means of a T-slot, and the positioning holes on the surface of the mounting block facilitate positioning work.

[0020] Preferably, the two mounting blocks are connected by a mounting frame, the inner wall of the mounting frame is provided with a display screen, and the outer surfaces of the two mounting frames opposite each other are fixedly provided with springs.

[0021] The technical effect of adopting the above-mentioned further solution is that the mounting frame is fixedly connected by two mounting blocks, which facilitates the protection of the internal display screen, while the mounting bracket provides fixed support for the second spring.

[0022] Preferably, one end of each of the two sets of springs is fixedly provided with a positioning pin, and one end of each of the two sets of positioning pins is movably embedded inside the positioning hole.

[0023] The technical effect of adopting the above-mentioned further solution is that the second spring provides a fixing function for the second positioning pin, while one end of the second positioning pin is movably embedded in the inside of the positioning hole, thus completing the positioning work of the mounting block.

[0024] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0025] 1. In this utility model, the stepper motor is started according to the length of the display screen, which drives the bidirectional lead screw to rotate, so that the mounting bracket at the symmetrical part of the outer surface moves along the guide rod to center. When the positioning pin on the surface of the second spring is pulled, the mounting block on the surface of the mounting frame is installed downward along the T-slot. When it is released, the positioning pin is embedded in the positioning hole by means of the restoring force, which completes the quick positioning work and facilitates the disassembly and maintenance work in the future.

[0026] 2. In this utility model, after installation, bolts and other parts are used to install the mounting base onto the vehicle body as a whole, and the mounting rod on the surface of the protective cover is embedded along the inside of the mounting groove. The positioning pin on the surface of the spring is pulled beforehand. When the mounting rod is embedded in the inside of the mounting groove, it is released so that the positioning pin is embedded in the inside of the round hole, thus completing the overall fixing of the protective cover, thereby providing protection for the display screen inside the mounting frame. The mounting frame is made of transparent or semi-transparent material for easy viewing. Attached Figure Description
