Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen installation, in particular to a plug-in structure for installing a split-type LED display screen. Background Art

[0002] The split LED display is a special LED display design that can divide a complete LED display into multiple independent units. Each unit can independently display different content, thus achieving a split-screen effect. Therefore, it is widely used in conferences, performances, exhibitions and other scenes. In the installation process of this type of display, snap-on, bolt-on, plug-in and other methods are usually used.

[0003] For example, patent document CN212906900U proposes a plug-in structure for mounting a split-type LED display screen. This plug-in structure utilizes the effect of a fixed block on a retaining ring to facilitate a certain degree of control over the extension of the output shaft, preventing it from being affected by the external environment. The elastic clip uses its own elasticity to engage the positioning groove to a certain extent, thereby securing the housing. The housing provides a certain degree of protection, and the support spring squeezes the annular plate. The elastic clip, in conjunction with the fixed block, provides a better connection between the plug-in block and the fixed block, facilitating quick and stable installation of the display screen.

[0004] However, most plug-in structures, including the above-mentioned technologies, are found to be inconvenient to use because multiple LED screens need to be installed in some temporary large-scale occasions. When they need to be dismantled after use, they need to be removed one by one, which brings more inconvenience to the dismantling work and consumes more time.

[0005] Therefore, it is necessary to provide a new plug-in structure for installing a split LED display screen to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0022] Please refer to Figure 1-Figure 5 ,in, Figure 1 A structural diagram of a preferred embodiment of the plug-in structure for installing a split-type LED display screen provided by the present invention; Figure 2 This is a schematic diagram of the front planar structure of the present utility model; Figure 3 This is a schematic cross-sectional view of the outer and inner frames of the present invention; Figure 4 This is a schematic diagram of the assembly of the socket and the wedge-shaped plug in the utility model; Figure 5The schematic diagram of the cross-sectional structure of the socket in the present invention. The plug-in structure of the split LED display screen includes: a mounting base 1, an outer frame 2 is fixedly mounted on the top of the mounting base 1, a first through slot 3 and a second through slot 4 are provided on the outer frame 2, the first through slot 3 is located above the second through slot 4, three plug-in ports 5 are provided on the top of the outer frame 2, the three plug-in ports 5 are all connected to the first through slot 3, a socket 7 is plugged into each of the three plug-in ports 5, and the bottoms of the three sockets 7 are in contact with the bottom inner wall of the first through slot 3, and the tops of the three sockets 7 are fixedly mounted. The split LED display 6 is equipped with a storage groove 8 on one side of the three sockets 7. The three storage grooves 8 are slidably installed with wedge-shaped plugs 9, and the tops of the three wedge-shaped plugs 9 are in contact with the top inner wall of the first through groove 3. The socket 7 is in contact with the bottom inner wall of the first through groove 3, and the wedge-shaped plugs 9 are in contact with the top inner wall of the first through groove 3, so that the socket 7 will not be loose, ensuring the stability of the split LED display 6 during use, and the tops of the three sockets 5 set above are One side of the outer frame 2 is provided with an inclined surface along the edge, which is adapted to the wedge-shaped plug block 9, and the two can produce sliding friction, so that when installing the split LED display 6, it is only necessary to insert the socket 7 toward the plug interface 5, without any other redundant operations, and a return spring 10 is provided in each of the three receiving grooves 8, and the two ends of the return spring 10 are respectively fixedly connected to the inner wall of one side of the receiving groove 8 and the wedge-shaped plug block 9, and a linkage rod 11 is slidably installed on one side of the outer frame 2, and one end of the linkage rod 11 extends to the second The three connecting bars 12 are fixedly installed in the through slot 4 and on the linkage rod 11. The tops of the three connecting bars 12 extend into the first through slot 3 and are slidably connected to the bottom of the first through slot 3. The three connecting bars 12 are fixedly installed with pushing rods 13. The three pushing rods 13 are respectively adapted to the three wedge-shaped plugs 9. By moving the pushing rods 13, the wedge-shaped plugs 9 can be pushed into the corresponding receiving slots 8, thereby simultaneously releasing the restrictions of the three sockets 7 and speeding up the dismantling efficiency.

[0023] In the above method, in order to drive the linkage rod 11 to move laterally, a motor 14 is fixedly installed on the top of the mounting base 1, and a disc 15 is fixedly installed on the end of its output shaft. An eccentric shaft 16 is fixedly installed on the disc 15, and an articulated arm 18 is rotatably installed on the eccentric shaft 16. A connector 17 is fixedly installed on the end of the linkage rod 11 close to the motor 14, and one side of the articulated arm 18 is rotatably connected to the connector 17. In this way, the linkage rod 11 can be driven to move laterally by rotating the disc 15 and utilizing the connection method of the articulated arm 18, so that the pushing rod 13 can smoothly push the wedge-shaped insert 9.

[0024] In this method, in order to provide a soft protection for the split LED display screen 6, three rubber pads 19 are fixedly installed on the top of the outer frame 2. The bottoms of the three split LED display screens 6 are in contact with the tops of the three rubber pads 19 respectively. The three sockets 7 pass through the three rubber pads 19 respectively and are slidably connected to the corresponding rubber pads 19. This can prevent the split LED display screen 6 from forming a hard contact with the outer frame 2.

[0025] In this embodiment, in order to limit the movement distance of the connecting strip 12, three limiting slides are opened on the bottom inner wall of the first through groove 3. The three connecting strips 12 pass through the three limiting slides respectively and contact the inner walls of the corresponding limiting slides. When the connecting strip 12 moves laterally to contact one side of the limiting slide, it indicates that the wedge-shaped plug 9 has completely entered the storage groove 8, and the pushing rod 13 will not extend into the storage groove 8, so that the socket 7 can be smoothly pulled out of the plug interface 5.

[0026] The working principle of the plug-in structure for installing the split LED display screen provided by the utility model is as follows:

[0027] When the split LED display 6 needs to be removed from the outer frame 2, the motor 14 is directly started in the forward direction. Its output shaft drives the disc 15 to rotate. When the disc 15 rotates, the eccentric shaft 16 on it rotates together, thereby pushing the linkage rod 11 away from the motor 14. At this time, the three connecting bars 12 are pushed together. When the three pushing rods 13 contact their corresponding wedge-shaped inserts 9, they squeeze and push the wedge-shaped inserts 9 until the connecting bars 12 move to contact one side of the limit slide, and the motor 14 is turned off. At this time, the wedge-shaped inserts 9 are completely pushed into the corresponding receiving slots 8, and the corresponding return springs 10 are compressed.

[0028] Then, directly pull up the split LED display 6 one by one and take it out directly;

[0029] Then, start the motor 14 in the reverse direction to bring the linkage rod 11 back to its original position;

[0030] When the cam 7 is in contact with the inner wall of the first through-slot 3, the wedge-shaped plug 9 is pushed into the receiving groove 8. At this time, the return spring 10 is in a compressed state. Until the bottom of the cam 7 contacts the bottom inner wall of the first through-slot 3, the wedge-shaped plug 9 is no longer restricted by foreign objects. The compressed return spring 10 directly releases the elastic force, and the three wedge-shaped plugs 9 pop out and finally contact the top inner wall of the first through-slot 3. In this way, the installation of a split LED display screen 6 is completed, and the remaining split LED display screens 6 can be installed in sequence in the same way as above.

[0031] Compared with the related art, the plug-in structure for installing the split LED display screen provided by the present invention has the following beneficial effects:

[0032] The present invention provides a plug-in structure for installing a split LED display screen. By designing a wedge-shaped plug block 9 and an inclined surface on one side of the plug interface 5, when installing the split LED display screen 6, the plug socket 7 can be directly inserted into the plug interface 5 from top to bottom without any unnecessary operation. When the plug socket 7 contacts the bottom inner wall of the first through groove 3, the wedge-shaped plug block 9 automatically pops out to complete the installation work. Moreover, when removing multiple split LED display screens 6 at a later stage, it is only necessary to start the motor 14 and use the three pushing rods 13 to push the three wedge-shaped plug blocks 9 into the corresponding storage grooves 8, so that the split LED display screens 6 can be directly taken out, thereby greatly saving the removal time and improving the removal efficiency.
