Description

Technical Field

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

[0002] At present, some large LED display screens are mostly spliced ​​together by multiple small LED display screens. The common installation method is that the staff fixes the mounting frame of the LED display screen on the wall in advance, and then the staff installs multiple small LED display screens on the mounting frame. However, since the back of the small LED display screen is equipped with independent connection lines, the staff needs to wire the lines on the back of the display screen and connect them to the bus on the mounting frame before the display screen can be used. Since the display screen is backed by the wall, the wiring process of the staff is more troublesome and it is not convenient to connect multiple lines.

[0003] To solve the above problems, we proposed a spliced ​​LED display screen. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 5A spliced ​​LED display screen includes a support plate 1, which is arranged in a rectangular shape. A plurality of mutually spliced ​​screen panels 13 are fixedly installed on the front side wall of the support plate 1. The four corners of the support plate 1 are fixedly connected to extension plates 2 outwardly, and the rear side walls of the extension plates 2 are fixedly connected to angle plates 3. The angle plates 3 include horizontal plates and vertical plates. The vertical plates of the angle plates 3 are fixedly connected to the corresponding extension plates 2. The horizontal plates of the angle plates 3 are fixedly inserted with vertical downward insertion shafts 4. The outer walls of the insertion shafts 4 are smoothly arranged. The rear sides of the insertion shafts 4 are arranged with vertical plates 5. The front side walls of the vertical plates 5 are provided with vertical slide grooves. Slide blocks 6 are slidably arranged in the slide grooves, and the ends of the slide blocks 6 extend forward from the slide grooves. A vertical socket 7 is provided at the end of the slider 6, and the socket 7 passes through the upper and lower outer walls of the slider 6. The inner wall of the socket 7 is smoothly set. The slider 6 is movably sleeved on the corresponding plug shaft 4 through the socket 7, that is, the slider 6 can slide up and down along the plug shaft 4. The top of the vertical plate 5 is fixedly connected with a horizontally set pad 8, and the pad 8 extends to the front side of the vertical plate 5. The pad 8 is located on the lower side of the horizontal plate of the angle plate 3. Affected by the gravity of the support plate 1, the horizontal plate of the angle plate 3 will be pressed on the pad 8. The lower side wall of the horizontal plate of the angle plate 3 is fixedly provided with a gasket. The function of the gasket is to reduce the friction between the pad 8 and the horizontal plate of the angle plate 3. The front end of the pad 8 is provided with an arc-shaped notch corresponding to the plug shaft 4.

[0021] A spring 9 is fixedly connected between the slider 6 and the corresponding pad 8. When the pad 8 is squeezed and contacted with the gasket on the horizontal plate of the angle plate 3, the slider 6 will be sleeved on the corresponding plug-in shaft 4 under the action of the elastic force of the spring 9. A connecting seat 10 is fixedly provided on the outer wall of the slider 6. The slider 6 can be driven to slide in the corresponding slide groove through the connecting seat 10. A vertical pull rod 11 is fixedly connected between the connecting seats 10 on the same side of the support plate 1. Operating the pull rod 11 can simultaneously drive the two sliders 6 on the same side to slide in the same direction. The rear side walls of the vertical plates 5 on the same side of the support plate 1 are commonly fixedly connected with a vertical positioning plate 12. A plurality of positioning holes 15 are opened on the positioning plate 12. The positioning plate 12 is sleeved on the prefabricated bolts of the wall through the positioning holes 15. The positioning plate 12 can be fixed to the wall by tightening the nuts.

[0022] The left and right side walls of the support plate 1 are fixedly connected with handles 14, and the handles 14 are located between the two extension plates 2 on the same side. The length of the slide groove on the vertical plate 5 is greater than twice the length of the plug-in shaft 4 to ensure that when the pull rod 11 is pulled downward to separate the slider 6 from the corresponding plug-in shaft 4, the slider 6 is not easy to slide out of the slide groove. When wiring operations need to be performed on the back of the support plate 1, the pull rod 11 on any side of the support plate 1 is pulled downward, and the pad 8 supports the horizontal plate of the angle plate 3 to keep the support plate 1 fixed. The pull rod 11 will simultaneously drive the two sliders 6 on the same side to slide downward until the slider 6 is separated from the corresponding plug-in shaft 4. At this time, the handle 14 on the same side of the support plate 1 is driven to drive the support plate 1 to deflect horizontally through the handle 14, so that the horizontal plate of the angle plate 3 is separated from the pad 8, and the back of the support plate 1 will be away from the wall, which is convenient for the staff to work on wiring.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
