Description

Technical Field

[0001] The utility model relates to the technical field of LED screen connection, in particular to a connection locking mechanism. Background Art

[0002] LED screens have good energy-saving effects and longer service life. When the lamp beads are well packaged and the lamps are assembled, the LED screens have good dust and water resistance and can adapt to outdoor working environments. Therefore, they are often used in outdoor lamps, light boxes, and advertising screens.

[0003] In some larger advertising screens, the length or width can reach several meters or tens of meters. For this type of LED screen, it is almost impossible to produce it directly. The usual practice is to splice small module screens to large screens. Large LED display screens are often temporarily built at some large exhibitions, outdoor stages, outdoor film and television events. Of course, there are also some large LED display screens used for construction indoors or outdoors, especially large LED display screens for outdoor advertising. Small module screens are designed to be waterproof and dustproof in most cases, and they also take heat dissipation into account. Therefore, small module screens often pile materials on the package and use a lot of metal to increase heat dissipation, making the small module screen heavier. More importantly, during the construction of large LED display screens, a large number of fasteners are often needed to lock the small module screens, and the disassembly and assembly speed is slow, making large LED display screens difficult to build.

The sliding end 221 is slidably disposed in the sliding groove 2122, and the toggle end 222 extends out of the lock box 21 through the opening 2123 of the lock box 21. The sliding end 221 is located in the lock box 21 and slides in the lock box 21, and the toggle end 222 is a structure for toggling the lock plate 22 to move during disassembly and assembly.

[0045] In some embodiments of the lock box 21, such as Figure 5 , Figure 6 As shown, the lock box 21 includes a bottom plate 211 and a box cover 212. The box cover 212 is buckled on the bottom plate 211, and one side of the box cover 212 is provided with an opening 2123. One end of the lock plate 22 is a sliding end 221, and the other end of the lock plate 22 is a toggle end 222. The sliding end 221 is slidably disposed in the lock box 21, and the toggle end 222 extends out of the lock box 21 through the opening 2123 of the lock box 21. The specific structure of the lock box 21 includes a box cover 212 and a bottom plate 211. The box cover 212 is buckled on the bottom plate 211, and the sliding end 221 slides in the box cover 212, and the toggle end 222 extends out of the box cover 212 through the opening 2123.

[0046] Furthermore, if Figure 6As shown, at least one support 2124 extending toward the bottom plate 211 is provided in the box cover 212, and a mounting hole 2125 is provided on the box cover 212, and the mounting hole 2125 penetrates through the support 2124 to the bottom plate 211. The bottom plate 211 is a structure directly connected to the frame 3, and the support 2124 is provided to maintain the spacing between the box cover 212 and the bottom plate 211, and when the lock box 21 is fixed to the frame 3, the lock box 21 is prevented from clamping the lock piece 22 due to excessive deformation.

[0047] Furthermore, if Figure 5 , Figure 6 As shown, the locking piece 22 is provided with a travel hole 224 extending along the moving direction thereof. One of the pillars 2124 passes through the travel hole 224. The travel hole 224 moves with the movement of the locking piece 22, and the travel hole 224 is limited by the pillar 2124. In this embodiment, the travel hole 224 is provided to limit the moving area of ​​the locking piece 22, and in particular, the locking position and the release position of the locking piece 22 can be limited by the pillar and the travel hole 224.

[0048] In some embodiments of the fixing member 11, such as Figure 2 , Figure 3 As shown, the fixing member 11 includes a fixing plate 111 and a collar 112. The fixing plate 111 is used to connect with the frame 3 and is a direct fixed installation structure. The collar 112 is arranged on the fixing plate 111. Specifically, the collar 112 can be a structure integrally formed, cast or processed with the fixing plate 111, or can be a structure additionally fixed to the fixing plate 111. The second through hole 113 passes through the collar 112 and the fixing plate 111. The movable rod 12 is provided with a guide groove 123 extending along its axial direction.

[0049] like Figure 3 As shown, the movable rod 12 is provided with a guide groove 123 extending along its axial direction. The lock assembly 1 also includes a guide pin 13, which is arranged on the fixing member 11, extends to the second through hole 113, and passes through the fixing member 11 and extends into the guide groove 123. Specifically, the guide pin 13 is arranged on the collar 112, and the guide pin 13 passes through the collar 112 and extends into the guide groove 123.

[0050] Through the cooperation of the guide groove 123 and the guide pin 13, the movable rod 12 is guided to move along its axial direction. The guide groove 123 limits the moving range of the movable rod 12 to prevent the movable rod 12 from slipping off the ring 112. The guide groove 123 can also limit the distance that the movable rod 12 extends into the first through hole 2121, ensuring that the slot 122 of the locking end 121 is located in the lock box 21, especially the slot 122 is aligned with the locking hole 223.

[0051] In some embodiments of the lock assembly 1, the lock assembly 1 also includes a locking handle 14, which is disposed on the movable rod 12 and is threadedly connected to the movable rod 12. By providing the locking handle 14, a hand-held structure is provided when the movable rod 12 is moved, thereby improving the convenience of moving the movable rod 12. The locking handle 14 is disposed on the movable rod 12, and itself can serve as a limiting structure, which limits the movable rod 12 from continuing to move toward the locking assembly 2 when the movable rod 12 abuts against the fixing member 11. By adjusting the position of the locking handle 14 on the movable rod 12, when the locking handle 14 abuts against the fixing member 11, the card slot 122 of the locking end 121 can be located in the lock box 21 and aligned with the locking hole 223. In addition, when moving the locking plate 22 to lock the movable rod 12, the locking handle 14 can also be rotated, the locking handle 14 abuts against the fixing member 11, the fixing member 11 limits the locking handle 14 from moving toward the locking assembly 2, and the movable rod 12 is moved away from the lock box 21 by the action of the thread, thereby locking the locking connection between the movable rod 12 and the locking plate 22.

[0052] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
