Description

Technical Field

[0001] This utility model relates to the field of LED display technology, specifically to an anti-detachment LED display for server racks. Background Technology

[0002] In modern electronic devices, LED displays for server racks are widely used. Currently, the most common way to install LED displays in server racks is by using the mounting groove formed between the elastic lugs and the mounting door panel. While this method meets basic installation requirements to some extent, it has significant drawbacks. During daily use, the elastic lugs are easily retracted due to accidental pressure. Once retracted, the LED display can easily detach from the cabinet door panel, severely affecting the stability of the installation. Poor connection stability can not only lead to loosening and shaking of the display during use, affecting display quality, but also cause equipment damage or even safety hazards due to accidental detachment. Therefore, developing a technical solution that effectively solves these problems and improves the installation stability of LED displays for server racks is of significant practical importance. Utility Model Content

[0003] In view of the shortcomings in the background technology, this utility model provides an anti-detachment LED display screen for server racks.

[0004] The technical solution adopted by this utility model is: an anti-detachment LED display screen for cabinets, including a shell, a limiting step extending outward from the front of the shell, a groove provided on the side of the shell, an elastic lug provided in the groove, an installation groove for installing a door panel formed between the elastic lug and the limiting step, and a fixing mechanism for preventing the elastic lug from retracting, a rotating groove provided on the side of the groove, a limiting groove provided in the rotating groove, and the fixing mechanism including a telescopic shaft and a return spring;

[0005] The telescopic shaft is provided with a limiting block. The telescopic shaft and the telescopic hole on the elastic lug are rotated and telescopically engaged. By rotating the telescopic shaft, the limiting block can be rotated out or in the limiting groove.

[0006] A retraction spring, one end of which is fixedly connected to the bottom wall of the telescopic hole and the other end of which is fixedly connected to the telescopic shaft, has an elastic pulling force to pull the telescopic shaft back into the telescopic hole.

[0007] Furthermore, the depth of the limiting groove is less than 2 / 3 of the outer shell wall thickness.

[0008] Furthermore, the limiting block is disposed on the end of the telescopic shaft.

[0009] Furthermore, a spring step is provided on the end of the telescopic shaft away from the limiting block, and an anti-detachment step is provided on the opening of the telescopic hole to prevent the telescopic shaft from detaching from the telescopic hole.

[0010] Furthermore, a rotating ring is provided on the telescopic shaft, and a number of protruding teeth are provided at equal intervals on the outer ring of the rotating ring.

[0011] The beneficial effects of this utility model are:

[0012] 1. By setting up a fixing mechanism, the problem of the elastic lugs easily retracting and causing the display screen to fall off in traditional installation methods is effectively solved. When the telescopic shaft is inserted into the rotating groove, the limiting block and the limiting groove cooperate with each other, and the telescopic shaft abuts against the bottom wall of the rotating groove, which can stably prevent the elastic lugs from retracting, greatly enhancing the connection stability of the display screen installation.

[0013] 2. The fixing mechanism does not hinder the original disassembly and assembly structure, making disassembly, maintenance, or replacement of the display screen simple and easy. Simply rotate the telescopic shaft to move the limit block out of the limit groove, and the return spring will quickly pull the telescopic shaft back into the telescopic hole, easily releasing the fixing. This design balances installation stability with ease of disassembly, significantly improving equipment maintenance efficiency and reducing maintenance costs.

[0014] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] This utility model provides an anti-detachment LED display screen for server racks.

[0024] In this embodiment, refer to Figure 1-5 The cabinet uses an anti-detachment LED display screen, including a housing 1. A limiting step 2 extends outward from the front of the housing 1. A groove 3 is provided on the side of the housing. An elastic lug 4 is provided in the groove. An installation groove 5 for installing a door panel is formed between the elastic lug 4 and the limiting step. It also includes a fixing mechanism to prevent the elastic lug from retracting. A rotating groove 6 is provided on the side of the groove. A limiting groove 7 is provided in the rotating groove 6. The fixing mechanism includes a telescopic shaft 8 and a return spring 9.

[0025] The telescopic shaft is provided with a limiting block 10. The telescopic shaft and the telescopic hole 11 on the elastic lug are rotatably telescopically engaged. By rotating the telescopic shaft, the limiting block can be rotated out or rotated in the limiting groove.

[0026] A retraction spring, one end of which is fixedly connected to the bottom wall of the telescopic hole and the other end of which is fixedly connected to the telescopic shaft, has an elastic pulling force to pull the telescopic shaft back into the telescopic hole.

[0027] In the above technical solution, the telescopic shaft in the fixing mechanism rotates and extends with the telescopic hole on the elastic lug. When the telescopic shaft is engaged in the rotating groove, rotating the shaft allows the limiting block to enter the limiting groove, preventing the telescopic shaft from retracting. Simultaneously, the telescopic shaft abuts against the bottom wall of the rotating groove, preventing the elastic lug from retracting. One end of the return spring is connected to the bottom wall of the telescopic hole, and the other end is connected to the telescopic shaft. When the display screen needs to be disassembled, rotating the telescopic shaft causes the limiting block to rotate out of the limiting groove, and the elastic force of the return spring pulls the telescopic shaft back into the telescopic hole, releasing the restriction on the elastic lug.

[0028] By adopting the above structure, the inward retraction of the elastic lugs is effectively prevented, greatly enhancing the stability of the LED display screen installed on the cabinet door and preventing the display screen from accidentally falling off.

[0029] Specifically, the depth of the limiting groove is less than 2 / 3 of the outer shell wall thickness.

[0030] In this embodiment, by limiting the depth of the limiting groove to less than 2 / 3 of the outer shell wall thickness, while ensuring that the limiting block enters the limiting groove to achieve the function of limiting the elastic lug, a sufficiently thick outer shell wall is retained to maintain the mechanical strength of the outer shell, so that the outer shell can withstand various external forces during the operation of the cabinet and ensure a stable installation environment for the display screen.

[0031] Specifically, the limiting block is located at the end of the telescopic shaft.

[0032] Specifically, a spring step 12 is provided on the end of the telescopic shaft away from the limiting block, and an anti-detachment step 13 is provided on the opening of the telescopic hole to prevent the telescopic shaft from detaching from the telescopic hole.

[0033] In this embodiment, the diameter of the spring step is larger than the opening diameter of the telescopic hole, which can prevent the telescopic shaft from being pulled out of the telescopic hole.

[0034] Specifically, a rotating ring 14 is provided on the telescopic shaft, and a number of protruding teeth 15 are provided at equal intervals on the outer ring of the rotating ring 14.

[0035] In this embodiment, the rotating ring is mounted on the telescopic shaft, and the evenly spaced protrusions on its outer ring increase the friction between the operator's hand and the telescopic shaft when the operator rotates it. This increased friction allows the operator to control the rotation of the telescopic shaft more stably and accurately, thereby making it easier to rotate the limiting block out of or into the limiting groove, and improving the controllability of the entire operation process.

[0036] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
