Description

Technical Field

[0001] The present invention relates to the field of display screens, and particularly to an LED display screen maintenance device. Background Art

[0002] An LED display screen generally includes a display screen box body and a plurality of display modules mounted on the display screen box body. During use, the display screen will incur certain wear and tear. In most cases, its maintenance requires removing the display module for repair or replacement. Currently, most display screens that require rear maintenance still adopt the traditional sheet metal box body structure, and the LED display module is fixed in the sheet metal box body structure.

[0003] As Figure 1 shown, an LED display module is usually composed of a plurality of LED light bars arranged in parallel at intervals, and fixing ribs for fixing the plurality of LED light bars are provided on both sides and in the middle. For easy loading and unloading, a plurality of magnets are provided on the ribs on both sides of the LED display module for directly adsorbing to corresponding positions of the sheet metal box body structure without being fixed by screws. During disassembly, the LED display module can be pushed out from the inside to the outside or pulled out from the outside to the inside of the sheet metal box body structure by a maintenance tool. Then, due to the low strength of the LED light bar, it is easy to cause damage to the LED light bar during disassembly, resulting in damage to the entire LED module. In addition, when pushing out or pulling out the LED display module forcefully, it is easy to cause the LED display module to fall and be damaged, resulting in inconvenient loading and unloading. Summary of the Invention

[0004] The purpose of the present invention is to provide an LED display screen maintenance device that facilitates technicians to load and unload LED modules.

The finger sliding block is fixedly connected to one end of a guide rod that is parallel to the support legs and passes downward through the handle frame. The other end of the guide rod is fixedly connected to the push block. A spring is sleeved on a part of the guide rod between the push block and the handle frame. When the finger sliding block moves upward, the spring is compressed, and the guide rod drives the push block away from the pad block. When the finger sliding block returns to its position, the spring pushes the push block to press on the pad block.

[0006] In an embodiment of the present invention, the plurality of pad blocks are strip-shaped and parallel to each other.

[0007] In an embodiment of the present invention, the finger sliding block is fixed to the guide rod by a guide rod screw.

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] The implementation of the present invention will be described in detail below in conjunction with specific embodiments.

[0022] As Figure 2 shown, in an embodiment of the present invention, a maintenance device for an LED display screen is provided for picking and placing LED modules in the LED display screen. The LED display screen maintenance device includes a handle 1, a hollow handle frame 2 disposed below the handle, a finger sliding block 3 disposed in the handle frame 2, a plurality of support legs 4 spaced apart below the handle frame 2, a plurality of foot pad blocks 5 disposed at the bottoms of the support legs 4, and a push block 6 pressed on the plurality of foot pad blocks 5 and perpendicularly intersecting the plurality of foot pad blocks 5. The plurality of foot pad blocks 5 are strip-shaped and parallel to each other.

[0023] One end of the finger sliding block 3 is fixedly connected to one end of a guide rod 7 passing downward through the handle frame 2, and the other end of the guide rod 7 is fixedly connected to the push block 6. The guide rod 7 is parallel to the support legs 4. The finger sliding block 3 is fixed to the guide rod 7 by a guide rod screw 8. A spring 9 is sleeved on a portion of the guide rod 7 between the push block 6 and the handle frame 2. It should be noted that the length of the spring 9 is just equal to or slightly greater than the distance between the push block 6 and the handle frame 2, so that the push block 6 closely adheres to the foot pad block 5.

[0024] The handle 1 is used for a user to hold the LED display screen maintenance device. The finger sliding block 3 is provided with a round hole and an arc-shaped depression structure for the user's finger to grip. The user can grip the finger sliding block 3 to drive the finger sliding block 3 to move upward, thereby driving the push block 6 away from the foot pad block 5. When the finger sliding block 3 moves upward, the spring 9 is compressed, and the guide rod 7 drives the push block 6 away from the foot pad block 5; when the finger sliding block 3 returns to its original position, the spring 9 pushes the push block 6 to press on the foot pad block 5.

[0025] Preferably, a buffer cotton 51 is provided on the foot pad block 5. A protruding step 61 is provided at the bottom of the push block 6, and the protruding step 61 perpendicularly intersects and contacts the plurality of foot pad blocks 5. A buffer pad 62 is provided at the bottom of the protruding step 61. When the foot pad block 5 and the push block 6 cooperate to clamp the LED display module, the buffer cotton 51 and the buffer pad 62 can play a role in protecting the LED display module and prevent the LED display module from being pinched.

[0026] In an embodiment of the present invention, the handle 1 is a hollow cylinder, and anti-slip patterns are provided on its surface. A plurality of guiding grooves (not labeled) corresponding to the positions of the support legs 4 are provided on the pushing block 6. The guiding grooves are arranged closely against the support legs 4 to prevent the pushing block 6 from deviating in position during the up and down movement.

[0027] As Figure 3 shown, when the LED display screen maintenance device of the present invention is used for post-screen maintenance of the LED display screen, the finger sliding block 3 is used to lift the pushing block 6, and the foot pad block 5 is inserted through the gap between the light bars of the LED display module and extended under the fixing ribs of the LED display module. Then, the finger sliding block 3 is released, so that the pushing block 6 returns to its position and abuts against a plurality of LED light bars of the LED display module. Pushing the LED display screen maintenance device outward can push out the LED display module. Since the LED display module is clamped and fixed by the LED display screen maintenance device when it is pushed out of the LED display screen box body, there is no risk of dropping and damage.

[0028] As Figure 4 shown, when the LED display screen maintenance device of the present invention is used for pre-screen maintenance of the LED display screen, the finger sliding block 3 is used to lift the pushing block 6, and the foot pad block 5 is inserted through the gap between the light bars of the LED display module and extended under the fixing ribs of the LED display module. Then, the finger sliding block 3 is released, so that the pushing block 6 returns to its position and abuts against a plurality of LED light bars of the LED display module. Pulling the LED display screen maintenance device outward can lift the LED display module. Since the LED display module is clamped and fixed by the LED display screen maintenance device when it is pulled out of the LED display screen box body, there is no risk of dropping and damage.

[0029] In summary, in the LED display screen maintenance device of the present invention, when the finger sliding block moves upward, the spring is compressed, and the guiding rod drives the pushing block away from the foot pad block. When the finger sliding block returns to its position, the spring pushes the pushing block to press on the foot pad block, so as to facilitate the staff to control the picking and placing of the LED module of the LED display screen by hand-held means, which can not only perform pre-screen maintenance but also facilitate post-screen maintenance.
