[0017] To facilitate understanding of the present application, a more comprehensive description of the present application will be provided below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present application.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are intended only to describe specific embodiments and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] See also Figure 1 The present invention provides an LED display screen with a protective device, comprising a module 1, a power supply box 2, a frame 3, and a protective device 4. The module 1 is arranged on one side of the frame 3, and the power supply box 2 is arranged on the other side of the frame 3. The frame 3 includes a first protective hole, and the module 1 includes a second protective hole. The protective device 4 secures the module 1 to the frame 3 through the first and second protective holes. The module 1 also includes a buckle 5.

[0022] Please also refer to Figures 2 to 4 The protection device 4 includes a knob 41, a limit column 42, a bead 43 and a fixing tube 44. The knob 41 is screwed (eg Figure 2 As shown in the figure, the limiting column 42 is fixed to one end of the limiting column 42, and the other end of the limiting column 42 and the shifting ball 43 are arranged in the fixing tube 44.

[0023] In a specific embodiment, a protrusion 45 is provided in the middle of the limiting post 42, and a connecting hole 46 is provided at the bottom of the other end of the limiting post 42. The cross-section of the limiting post 42 includes a long side 47 and a short arc side 48, where the long side is referred to as the narrow connection position and the short arc side is referred to as the wide connection position. A spring 49 is provided between the knob 41 and the limiting post 42, and a limiting groove 442 and a ball-moving hole 441 are provided in the fixing cylinder 44. Specifically, the diameter of the ball-moving hole is smaller than the diameter of the ball, so that when the limiting post is rotated 90 degrees, the ball is retained in the hole. The connecting hole 46 can be, but is not limited to, a hexagonal socket.

[0024] like Figure 5 As shown, Figure 5 This is a schematic diagram of disassembling an LED display screen with a protective device in one embodiment of the present invention. It can be unlocked from both the back and the front of the box. The back is unlocked by rotating the knob, and the front is unlocked by using a hexagonal wrench (the wrench matches the connecting hole). In the unlocked state, the bead contacts the narrow position and retracts; it can be unlocked by extending it into the inner hexagonal hole of the limiting column through the second protective hole of the module. When locked, the bead contacts the wide position and extends out. At this time, the buckle is reversed to prevent the protective device from detaching from the buckle. At this time, the module cannot be removed from the frame. It should be noted that in both the locked and unlocked states, the protrusion on the limiting column will fall into the limiting groove, and the spring will prevent it from automatically falling out.

[0025] The knob on the rotating protection device of the utility model causes the ball in the protection device to be pushed out and engaged with the buckle on the module, so that the LED display module can be quickly and safely fixed on the frame; at the same time, when maintaining the LED display screen, the protection device can be unlocked with a wrench through the module opening on the module surface, making the entire maintenance process simple and convenient, and improving the assembly efficiency and maintenance and disassembly efficiency of the LED display screen.

[0026] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] It should be noted that the preferred embodiments of the present invention are given in the specification and drawings of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in the specification. These embodiments do not serve as additional limitations on the content of the present invention. The purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. In addition, the above-mentioned technical features continue to be combined with each other to form various embodiments not listed above, which are all considered to be within the scope of the description of the present invention; further, it is clear to those skilled in the art that improvements or changes can be made based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to the present invention.
