Problems solved by technology

[0002] The traditional small-pitch LED display does not have a protective light device. Due to the characteristics of the industry, the single box of the LED display is designed as a frameless mechanism, and the light-emitting lamp beads are small in size. The lamp beads are welded on the printed circuit board with solder paste. The lamp bead on the edge of the box will fall off or be damaged when it receives slight touch or external force, resulting in poor product performance. It is also very difficult to repair or replace a lamp bead. If the pad on the circuit board is damaged, it may directly As a result, it cannot be repaired, and the entire cabinet will be scrapped due to a damaged lamp bead, causing major economic losses
[0003] There are also some small-pitch LED displays that use additional accessories to protect the lights, that is, install a protective edge on the edge of the cabinet through screws or other methods to achieve the purpose of protecting the lights; this method is troublesome to install. The disassembly of accessories is cumbersome, and the removed extra accessories are easy to lose

Embodiment 1

[0028] refer to Figures 1 to 4 , is a structural schematic diagram of a lamp protection structure scheme of an LED display screen according to the present invention. The entire lamp protection structure is composed of two major parts, namely the base 1 and the base receiving part 2 . in figure 1 and figure 2 is a schematic diagram of the structure of the base 1 in two different directions, image 3 and Figure 4 is a schematic diagram of the structure of the base housing part 2 in two different directions. refer to figure 2 , The bottom of the base 1 is provided with a sliding post 11 , a spring 12 and a positioning nail 13 . The sliding column 11 and the positioning nail 13 can be integrally formed with the base 1 , or they can be respectively installed on the bottom of the base 1 later. The number and distribution of the positioning pins 13 can be determined according to specific implementation needs. The preferred solution is two positioning pins 13, and the posit...

Embodiment 2

[0031] refer to Figures 1 to 4 , the lamp protection structure scheme of the LED display screen can be further optimized on the basis of Embodiment 1, that is: the base housing part 2 is also provided with a stepped groove 24 and a boss 25; the base 1 is provided with a convex part matching the stepped groove 24 18. The sliding groove 21 extends from the stepped groove 24 to the corner direction to the boss 25 . Two first positioning holes 22 are disposed on the boss 25 and distributed on both sides of the sliding groove 21 , and the second positioning holes 23 are disposed in the stepped groove 24 and distributed on both sides of the sliding groove 21 . The base accommodating part 2 is also provided with a stop groove 26, and the bottom of the corresponding base 1 is provided with a stop protrusion 19. When the lamp protection structure is completely closed, the stop protrusion 19 is placed in the stop groove 26, When the lamp protection structure is closed, it can be comp...

Embodiment 3

[0033] refer to Figures 1 to 8 , The lamp protection structure scheme of the LED display screen is further optimized on the basis of Embodiments 1 and 2.

[0034] As shown in the figure, the base 1 is also provided with a handle 14 , an operation slot 15 and a magnet 16 . In a preferred solution, the handle 14 is an iron mini handle, and the handle is T-shaped. One end of the handle 14 is connected with the base 1 through a structure such as a rotating shaft to realize rotation. For the convenience of operation, there is a rib 141 in the operation groove 15 which is consistent with the shape of the handle 14 . A magnet 16 is disposed on the rib 141 . When the handle 14 is closed, the handle 14 is accommodated in the operation slot 15 and overlapped with the rib 141 , while the other end of the handle 14 is attracted by the magnet 16 . The handle 14 is opened, rotated to the maximum angle and lifted out, the positioning nail 13 can be separated from the first positioning h...

Abstract

The invention discloses a lamp protection structure of an LED display screen. The lamp protection structure is arranged on a box body frame and is characterized by comprising a base (1) and a base accommodating portion (2) arranged on the box body frame, a sliding column (11), a spring (12) and positioning nails (13) are arranged at the bottom of the base (1), a sliding groove (21) and first positioning holes (22) are formed in the base accommodating portion (2), the sliding column (11) penetrates through the sliding groove (21) and is sleeved with the spring (12), one end of the spring (12) is limited at the end of the sliding column (11), and the other end of the spring (12) abuts against the edge of the sliding groove (21), and when the sliding column (11) slides in the sliding groove (21) to arrange the positioning nails (13) in the first positioning holes (22), the local portion of the base (1) is externally arranged on the box body frame. The novel structural scheme is provided for protection of lamp beads on edges or at corners, and the lamp protection structure is convenient and quick to operate and good in applicability and stability and does not affect the splicing effect of a box body.
