Description

Technical Field

[0001] The utility model relates to the technical field of display screens, in particular to a combined box LED display screen. Background Art

[0002] The box of the box-type LED display screen is usually made of metal materials (such as aluminum alloy, magnesium alloy, etc.), and has good structural strength and protection performance. LED display screen modules are installed inside the box, and these modules are interconnected through connecting wires and a control system to form a complete display screen.

[0003] Chinese authorized announcement number CN215814920U discloses a combined box LED display screen, including a first box body and a second box body. A plurality of LED modules are arranged on the outer surface of the first box body or the second box body, and the first box body and the second box body are attached at 90°. The box-type LED display screen is combined by splicing two box bodies. The edges at one end of the first box body are directly attached to the edges at one end of the second box body to combine the box-type LED display screen; it solves the problems that the box-type LED display screen is not easy to assemble, the corners and edges are easily collided during the splicing process, the verticality cannot be guaranteed, and the gap between the two planar LED display screens after splicing is large, resulting in poor display visual effects.

[0004] However, the device has the following defects when in use: Although the device can assemble multiple box bodies into one body by the cooperation of positioning holes and positioning columns, the side strength of two adjacent box bodies is low, and the two box bodies are not fixed, which easily causes the assembled box bodies to scatter. In view of the above defects: For this reason, we propose a combined box LED display screen. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects in the prior art that the side strength of two adjacent box bodies is low, and the two box bodies are not fixed, which easily causes the assembled box bodies to scatter, and to propose a combined box LED display screen.

[0006] In order to solve the problems existing in the prior art, the utility model adopts the following technical scheme:

[0007] A combined box LED display screen includes an outer frame and an LED display screen module. An assembly structure is arranged between the outer frame and the LED display screen module, and an assembly structure is arranged on the surface of the outer frame. The assembly structure includes a horizontal limiting component, a vertical limiting component and a locking component;

[0008] The locking component includes connecting plates and locking plates respectively fixedly installed on two side surfaces of the outer frame, a magnetic adsorption component arranged inside the connecting plate, and a plugging component arranged on the surface of the locking plate;

[0009] The plug-in component includes a sliding hole formed on the surface of the locking plate and an iron plug slidably mounted on the inner wall of the sliding hole;

[0010] The magnetic adsorption component includes a rotating groove formed on the inner wall of the connecting plate, a magnet rotatably mounted on the inner wall of the rotating groove, and a slot formed on the right side surface of the connecting plate. The rotating shaft of the magnet extends to the outside of the connecting plate and is provided with a knob.

[0011] Preferably, a compression spring is sleeved on the surface of the iron plug. One end of the compression spring is fixedly connected to one side of the locking plate, and the other end of the compression spring is fixedly connected to the handle end of the iron plug.

[0012] Preferably, the central axis of the iron plug is coaxial with the central axis of the slot.

[0013] Preferably, the lateral limiting component includes a limiting block fixedly mounted on the right side surface of the outer frame and a strip-shaped groove formed on the left side surface of the outer frame for the limiting block to pass through.

[0014] Preferably, the longitudinal limiting component includes a limiting pin fixedly mounted on the upper surface of the outer frame and a limiting groove formed at the bottom end of the outer frame.

[0015] Preferably, the assembly structure includes a baffle fixedly mounted on the inner wall of the outer frame and a mounting bracket fixedly mounted on the back surface of the LED display module. Both the mounting bracket and the surface of the baffle are provided with bolt holes for fasteners to pass through.

[0016] Preferably, a dust-proof door that can block the outer frame is rotatably connected to the back surface of the outer frame.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] 1. By setting the assembly structure, insert the limiting block on one side of one outer frame into the strip-shaped groove on one side of the other outer frame. At this time, the limiting pin on one of the outer frames will be inserted into the limiting groove on the other outer frame, so as to preliminarily limit the two outer frames. Then, rotate the knob to drive the magnet to rotate to the position of the slot. The iron plug can be adsorbed by the magnet and enter the slot, so as to lock and fix the two outer frames by using the iron plug, thereby improving the stability after the two outer frames are connected, making the assembled box-type LED display more stable. Moreover, after rotating the magnet to a position where it disengages from the slot, the compression spring will reset and drive the iron plug to disengage from the slot, so that the two outer frames can be quickly assembled and disassembled.

[0019] 2. By setting the assembly structure, place the mounting frame on the baffle, and then use external fasteners to fix the baffle and the mounting frame, so that the LED display module can be fixed on the outer frame. When a certain LED display module on the assembled box LED display is damaged, the dust-proof door can be opened to expose the fasteners, and then the fasteners can be screwed out to separate the mounting frame from the baffle, and then any LED display module can be replaced individually, without having to remove the outer frame in sequence until the damaged LED display module, which facilitates the maintenance.
