Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED display installation technology, specifically to a shock-resistant and vibration-proof precision assembly screw for LED displays. Background Technology
[0002] In the field of LED display installation, loose screws can cause screen displacement, poor circuit contact, or even detachment due to outdoor wind vibration and high-frequency vibration of stage equipment.
[0003] In the existing technology, a protective shell is set on the outside of the elastic element to protect it. The closed space formed by the protective shell blocks the convection heat dissipation channel between the elastic element and the outside world. The heat dissipation efficiency is extremely low by relying solely on heat conduction. This will cause the elastic element to deteriorate due to heat accumulation, and the metal spring will soften due to high-temperature annealing and have a shortened fatigue life. Therefore, we propose a shockproof and vibration-resistant precision assembly screw for LED display screens. Utility Model Content
[0004] The purpose of this invention is to provide a shock-resistant and vibration-proof precision assembly screw for LED displays, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a shock-resistant and vibration-proof precision assembly screw for LED displays, comprising a nut, a bolt connected to the nut, a nut on the bolt, and a washer on the bolt, and further comprising:
[0006] A protective assembly, the protective assembly including a sealing shell connected to a nut, a sliding shell slidably connected to the sealing shell, and a gasket connected to the side of the sliding shell away from the sealing shell.
[0007] A heat dissipation assembly includes a rotating shaft rotatably connected to a sealing shell, a baffle rotatably connected to the rotating shaft, a spring connecting the baffle and the sealing shell, and a vent on the side of the sealing shell near the baffle.
[0008] Furthermore, a driving assembly is provided inside the sealing shell. The driving assembly includes a bimetallic strip, and a stop rod is connected to the bimetallic strip. The end of the stop rod away from the bimetallic strip is connected to a baffle.
[0009] The above technical solution involves setting up a drive component to drive the baffle to rotate, thereby exposing the vent.
[0010] Furthermore, a limiting component is provided inside the sealing shell on the side near the bimetallic strip. The limiting component includes a limiting groove formed in the inner wall of the sliding shell, and a limiting block is slidably connected in the limiting groove. The limiting block is connected to the bimetallic strip.
[0011] The above technical solution is adopted: by setting a limiting component, the bimetallic strip is limited during the process of being heated and bent, so as to prevent it from slipping.
[0012] Furthermore, the nut is provided with an anti-vibration component, which includes a spring connected to the nut, with the end of the spring away from the nut connected to a washer, and the spring is provided with damping.
[0013] The above technical solution involves setting up anti-vibration components to absorb vibration energy through elastic deformation, thereby reducing stress damage to equipment caused by impact and vibration.
[0014] Furthermore, a spring clip is provided on the side of the nut near the washer.
[0015] The above technical solution involves setting up a spring sheet. In a vibrating environment or under external impact, the spring sheet dissipates energy through deformation, reducing the displacement or damage to the equipment caused by vibration.
[0016] Furthermore, both the gasket and the spring are provided with heat dissipation holes.
[0017] The above technical solution involves setting heat dissipation holes to promptly dissipate the heat generated by the gaskets and springs.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] In this invention, by setting up a heat dissipation component, the heat generated by the elastic element due to vibration and friction can be quickly removed, avoiding problems such as softening of metal springs during annealing and degradation of rubber elastomer molecular chains. This solves the problem in the prior art where a protective shell is set on the outside of the elastic element for protection. The enclosed space formed by the protective shell blocks the convection heat dissipation channel between the elastic element and the outside world, and the heat dissipation efficiency relying solely on heat conduction is extremely low. This leads to the deterioration of the elastic element's performance due to heat accumulation, and the softening of metal springs during high-temperature annealing and shortened fatigue life.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] like Figures 1-5 As shown, this utility model provides a technical solution: a shock-resistant and vibration-proof precision assembly screw for LED displays, including a nut 1, a bolt 2 connected to the nut 1, a nut 3 set on the bolt 2, and a washer 4 set on the bolt 2, and further including:
[0035] The protective component 6 includes a sealing shell 61 connected to the nut 1, a sliding shell 62 slidably connected to the sealing shell 61, and the side of the sliding shell 62 away from the sealing shell 61 connected to the gasket 4.
[0036] The heat dissipation assembly 7 includes a rotating shaft 71 rotatably connected to the sealing shell 61, a baffle 72 rotatably connected to the rotating shaft 71, an elastic element 73 connected between the baffle 72 and the sealing shell 61, and a vent 74 opened on the side of the sealing shell 61 near the baffle 72.
[0037] A drive assembly 8 is provided inside the sealed housing 61. The drive assembly 8 includes a bimetallic strip 81, and a push rod 82 is connected to the bimetallic strip 81. The end of the push rod 82 away from the bimetallic strip 81 is connected to the baffle 72.
[0038] Specifically, the sealing shell 61 protects the shock-absorbing component 5. When the internal heat is too high, the bimetallic strip 81 will bend after being heated, thereby driving the abutment rod 82 to move. The abutment rod 82 drives the baffle 72 to rotate through the rotating shaft 71, allowing the vent 74 to leak out for heat dissipation. When the internal temperature drops, the bimetallic strip 81 returns to its original shape, driving the abutment rod 82 to move back. The baffle 72 automatically bounces back to its original position through the elastic force of the elastic element 73.
[0039] Furthermore, such as Figure 2 and Figure 3 As shown: A spring piece 10 is provided on the side of the nut 1 near the washer 4. Both the washer 4 and the spring piece 10 are provided with heat dissipation holes 11. In a vibrating environment or under external impact, the spring piece 10 consumes energy through deformation, reducing the displacement or damage to the equipment caused by vibration.
[0040] The above solution also requires that the bimetallic strip 81 be restrained during the bending process under heat, such as... Figure 5 As shown: A limiting component 9 is provided inside the sealing shell 61 on the side near the bimetallic strip 81. The limiting component 9 includes a limiting groove 91 formed in the inner wall of the sliding shell 62. A limiting block 92 is slidably connected in the limiting groove 91. The limiting block 92 is connected to the bimetallic strip 81. When the bimetallic strip 81 is heated and bent, it will drive the limiting block 92 to slide synchronously in the limiting groove 91, thereby limiting the bimetallic strip 81.
[0041] The above solutions also include the requirement to incorporate seismic resistance into bolt 2, such as... Figure 2 As shown: A shock-absorbing component 5 is provided on the nut 1. The shock-absorbing component 5 includes a spring 51 connected to the nut 1. The end of the spring 51 away from the nut 1 is connected to the washer 4. A damper 52 is provided inside the spring 51. By setting the shock-absorbing component 5, vibration energy is absorbed through elastic deformation, thereby reducing stress damage to the equipment caused by impact and vibration.
[0042] The working principle provided by this utility model is as follows: Figures 1-5 As shown: When vibration occurs, the spring 51 and damper 52 absorb the vibration energy, reducing stress damage to the equipment caused by impact and vibration. The sealing shell 61 protects the anti-vibration component 5. When the internal heat is too high, the bimetallic strip 81 will bend after being heated, thereby driving the abutment rod 82 to move. When the bimetallic strip 81 is heated and bent, it will drive the limit block 92 to slide synchronously in the limit groove 91, thereby limiting the bimetallic strip 81. The abutment rod 82 drives the baffle 72 to rotate through the rotating shaft 71, allowing the vent 74 to leak out for heat dissipation. When the internal temperature drops, the bimetallic strip 81 returns to its original shape, driving the abutment rod 82 to move back. The baffle 72 automatically bounces back to its original position through the elastic force of the elastic element 73.
[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
