Screws play a vital role in industry, and as long as industry exists on Earth, the function of screws will always be important. Screws are a common invention of human production and life over thousands of years. In terms of application, they are humankind's greatest invention. LED displays require screws for fixing during installation. Because the screws used are small, they need to be manufactured using high-strength materials to prevent damage and stripping.

[0003] Chinese Patent Publication No. CN220435216U discloses an anti-loosening screw, including a bolt and a fixing plate. The bolt is connected to a nut with a turning groove. The fixing plate is connected to a positioning post and a sliding rod. The bolt has a first sliding groove, and the side wall of the turning groove has a through groove and other structures. By nailing the positioning post into the fixed object and inserting the limiting rod into the limiting hole, the fixing plate and the bolt become a single entity, thus preventing the bolt from easily rotating or moving up and down, improving the bolt's stability and effectively preventing the screw from loosening.

[0004] While the above technical solution can prevent bolts from loosening, it requires additional tools to achieve the anti-loosening effect during installation, and it is inconvenient to disassemble and reuse after installation, thus making it inconvenient for users. Utility Model Content

[0005] The purpose of this utility model is to provide a self-locking anti-loosening LED display fixing screw, which solves the problem that existing screws require external tools to achieve the anti-loosening effect and are inconvenient to install and disassemble by working together with anti-loosening components and limiting components.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A self-locking anti-loosening LED display fixing screw includes a screw rod, one end of which is fixedly connected to a nut, and the end of the screw rod away from the nut is tapered. It further includes: a groove formed on the screw rod, a silicone ring installed in the groove, an anti-loosening nut threaded onto the outside of the screw rod, the anti-loosening nut having uniformly distributed anti-slip textures on its outer surface; an anti-loosening component installed inside the anti-loosening nut to prevent the anti-loosening nut from loosening from the screw rod; and a limiting component installed on the anti-loosening nut to limit the movement of the anti-loosening component.

[0008] Preferably, the anti-loosening component includes a circular groove inside the anti-loosening nut, and symmetrical sliding rods are arranged inside the circular groove. The ends of the two sliding rods that are close to each other are rotatably connected to positioning beads, and the ends of the two sliding rods that are far apart from each other pass through the anti-loosening nut and are fixedly connected to a lever.

[0009] Preferably, an arc-shaped plate is fixedly connected to the outside of the two slide rods, and a return spring is fixedly connected to the outside of the two arc-shaped plates. The return spring is sleeved on the outside of the slide rods, and the end of the return spring away from the arc-shaped plate is fixedly connected to the inner wall of the circular groove.

[0010] Preferably, compression springs are symmetrically fixedly connected inside both of the two arc-shaped plates, and auxiliary beads are fixedly connected to the outside of each of the multiple compression springs.

[0011] Preferably, the limiting component includes sleeves, which are symmetrically installed on the outside of the anti-loosening nut. Both sleeves are slidably connected to limiting rings, and both limiting rings are provided with openings.

[0012] Preferably, both slide rods are fixedly connected to limit blocks on their exteriors, the width of both limit blocks is smaller than the opening, and both slide rods are rotatably connected to the limit ring.

[0013] Preferably, a connecting rod is fixedly connected to the bottom of the nut, and a screw cap is connected to the outside of the connecting rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model is equipped with an anti-loosening component. The nut has a positioning bead and an auxiliary bead, which can be inserted into the silicone ring inside the groove. The silicone ring is soft and elastic, which can effectively prevent the anti-loosening nut from loosening with the screw.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] The following description is intended to disclose the present invention and to enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0029] Example 1: Please refer to Figures 1-7 The diagram shows a self-locking, anti-loosening LED display fixing screw, including a screw rod 1, one end of which is fixedly connected to a nut 2. The screw rod 1 and the nut 2 are made of high-strength stainless steel. The high strength ensures that the screw will not deform or break when subjected to large tensile and compressive forces, providing reliable fixing support for the LED display. The end of the screw rod 1 away from the nut 2 is tapered, which facilitates alignment with the mounting hole and easy drilling. The screw rod 1 also includes a groove 9 formed on the screw rod 1, in which a silicone ring 10 is installed. The silicone ring 10 is made of high-quality silicone rubber. Silicone rubber not only possesses good elasticity, allowing it to tightly conform to the screw 1 and the fixed object, enhancing friction, but also exhibits high and low temperature resistance. The screw 1 is externally threaded with an anti-loosening nut 5, which is made of high-strength alloy steel with a special anti-rust treatment. It not only has high hardness and can withstand large torques, but also has good wear resistance. The anti-loosening nut 5 has uniformly distributed anti-slip textures 6 on its exterior, increasing friction between the nut and the operator's hand or tools, facilitating tightening and loosening. Additionally, an anti-loosening component 7 is installed inside the anti-loosening nut 5 to prevent the anti-loosening nut 5 from loosening from the screw 1. Furthermore, a limiting component 8 is installed on the anti-loosening nut 5 to limit the movement of the anti-loosening component 7.

[0030] Furthermore, the anti-loosening component 7 includes a circular groove 11 inside the anti-loosening nut 5. Symmetrical sliding rods 12 are arranged inside the circular groove 11. Positioning beads 14 are rotatably connected to the ends of the two sliding rods 12 that are close to each other. The positioning beads 14 are made of stainless steel. When the positioning beads 14 contact the silicone ring 10 inside the groove 9, they will compress the silicone ring 10, thus forming a snap-fit ​​structure, which can prevent the anti-loosening nut 5 from loosening from the screw 1. The ends of the two sliding rods 12 that are far apart from each other both penetrate the anti-loosening nut 5 and are fixedly connected to a lever 17. The lever 17 is arc-shaped, making it convenient for the user to use the sliding rods 12 to move the positioning beads 14 out of the screw 1.

[0031] Furthermore, an arc-shaped plate 13 is fixedly connected to the outside of the two slide rods 12. Both the slide rods 12 and the arc-shaped plate 13 are made of aluminum alloy. Aluminum alloy has the characteristics of being lightweight and high-strength, which can reduce the overall weight of the screw while ensuring the durability and reliability of the component. A return spring 15 is fixedly connected to the outside of the two arc-shaped plates 13. The return spring 15 is sleeved on the outside of the slide rod 12. The end of the return spring 15 away from the arc-shaped plate 13 is fixedly connected to the inner wall of the circular groove 11. The return spring 15 can drive the slide rod 12 and the positioning bead 14 to return to their original position.

[0032] Specifically: compression springs 16 are symmetrically fixedly connected inside the two arc-shaped plates 13, and auxiliary beads 22 are fixedly connected to the outside of the multiple compression springs 16. The auxiliary beads 22 are made of the same material as the positioning beads 14 and can be evenly engaged with the silicone ring 10, thereby effectively preventing the anti-loosening nut 5 and the screw 1 from loosening.

[0033] Example 2: This embodiment is a further explanation of Example 1, based on... Figure 4 , Figure 6 and Figure 7 As shown, it is worth noting that the limiting component 8 includes a sleeve 18, which is made of stainless steel. The sleeves 18 are symmetrically installed on the outside of the anti-loosening nut 5. Both sleeves 18 are slidably connected to a limiting ring 19 inside. Both limiting rings 19 are provided with an opening 20. The limiting rings 19 are made of aluminum alloy.

[0034] Specifically, both slide rods 12 are fixedly connected to limit blocks 21 on their exteriors. The width of both limit blocks 21 is smaller than that of the opening 20. Both slide rods 12 are rotatably connected to the limit ring 19. When the lever 17 is rotated, the slide rods 12 can be rotated, which in turn causes the limit blocks 21 to align with the opening 20. This allows the lever 17 to be pushed outward, causing the slide rods 12 and the limit ring 19 to move outward. This disengages the positioning bead 14 and the auxiliary bead 22 from the screw 1, reducing the friction between the anti-loosening nut 5 and the screw 1, making it easier to unscrew the anti-loosening nut 5 and complete the disassembly operation.

[0035] Further reference Figure 5 As shown, a connecting rod 3 is fixedly connected to the bottom of the nut 2, and a screw cap 4 is connected to the outside of the connecting rod 3. By rotating the connecting rod 3 through the screw cap 4, the nut 2 is gradually tightened, thus achieving the initial fixation of the LED display screen without the need for external tools, thereby improving the convenience and speed of installation and disassembly.

[0036] The principle behind this solution is as follows:

[0037] First, pass the tapered end of the screw 1 through the mounting hole of the LED display screen, and rotate the connecting rod 3 by rotating the nut 4 to gradually tighten the nut 2, thus achieving the initial fixation of the LED display screen;

[0038] Secondly, screw the anti-loosening nut 5 onto the screw 1. When the positioning bead 14 and auxiliary bead 22 inside the nut reach the surface of the groove 9, they will automatically be locked into the silicone ring 10 under the action of the return spring 15 and the compression spring 16. Since the silicone ring 10 is soft and elastic, it can wrap the positioning bead 14 and auxiliary bead 22, thereby effectively preventing the anti-loosening nut 5 and the screw 1 from loosening.

[0039] Finally, when it is necessary to remove the anti-loosening nut 5, rotating the lever 17 can drive the slide rod 12 to rotate, thereby causing the limiting block 21 to correspond with the opening 20. Then, the lever 17 can be moved outward, causing the slide rod 12 and the limiting ring 19 to move outward, so that the positioning bead 14 and the auxiliary bead 22 are disengaged from the screw 1, reducing the friction between the anti-loosening nut 5 and the screw 1, making it easier to unscrew the anti-loosening nut 5 and complete the disassembly operation.

Furthermore, under the teachings of this utility model, modifications to these features and embodiments can be made to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
