Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum profiles, specifically to an aluminum profile with a screw-limiting anti-loosening structure. Background Technology
[0002] Aluminum profiles are widely used in various building and industrial settings due to their excellent properties such as light weight and corrosion resistance. They are often installed on roofs or other base plates using fasteners such as screws.
[0003] However, in actual use, due to the lack of an effective anti-loosening structure between the aluminum profile and the screw, the screw is prone to loosening or even falling off after being subjected to vibration, external impact, or long-term use. This not only affects the stability and firmness of the aluminum profile installation, leading to structural safety hazards, but may also cause a series of problems such as equipment failure and component damage, increasing maintenance costs and downtime, and bringing many inconveniences to production and daily life.
[0004] Therefore, developing an aluminum profile structure that can effectively prevent screws from loosening is of great practical significance. Utility Model Content
[0005] The purpose of this utility model is to provide an aluminum profile with a screw-limiting and anti-loosening structure to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an aluminum profile with a screw limiting and anti-loosening structure, comprising an aluminum profile body, a long-shank screw inserted into the surface of the aluminum profile body, and pre-reserved grooves integrally formed on the four side walls of the aluminum profile body. The pre-reserved grooves are provided with screw anti-loosening components. After the long-shank screw penetrates the aluminum profile body, it squeezes one end of the screw anti-loosening component to produce elastic deformation. The screw anti-loosening component rebounds and supports the long-shank screw to prevent it from being loosened. The screw anti-loosening limiting component is provided in two sets, which are distributed on both sides of the long shank screw. The two sets of screw anti-loosening limiting components are squeezed to clamp and limit the long shank screw.
[0007] Preferably, the screw anti-loosening limiting component includes a metal strip and a rubber strip. The metal strip has a "C"-shaped strip structure. The length of the metal strip and the aluminum profile body are equal. A gap is left between one end of the metal strip and the reserved groove. The rubber strip is fixed in the gap between one end of the metal strip and the reserved groove, and the length of the long side of the rubber strip is equal to the length of the long side of the metal strip.
[0008] Preferably, after the long-shank screw penetrates the aluminum profile body, one end of the long-shank screw compresses the metal strips and rubber strips on both sides to produce deformation. The rubber strips and metal strips rebound and support one end of the long-shank screw to move back, and the long-shank screw and the through hole of the aluminum profile body are tightly engaged.
[0009] Preferably, a rubber clip is fixed to one end of the metal strip near the long shank screw. The long side of the rubber clip is equal to the long side of the metal strip. After the two metal strips are clamped and moved toward the long shank screw and deformed, the rubber clip is clamped between the long shank screw and the metal strips.
[0010] Preferably, the surface of the reserved groove is provided with holes for inserting long-handled screws.
[0011] Compared with the prior art, the beneficial effects of this utility model are: The aluminum profile with screw limiting and anti-loosening structure proposed in this utility model has a screw anti-loosening component set in the reserved groove of the aluminum profile body. When the long shank screw passes through the aluminum profile body and is screwed and locked, one end of the long shank screw squeezes the metal strips and rubber strips on both sides to deform. The elasticity of the rubber strips and metal strips supports one end of the long shank screw to move back, so that the long shank screw and the through hole of the aluminum profile body are tightly engaged, effectively preventing the long shank screw from falling off. This greatly enhances the stability and firmness of the aluminum profile installation and reduces the structural safety hazards caused by screw loosening.
[0012] The screw anti-loosening limiting component has two sets distributed on both sides of the long shank screw. Pressing the two sets of screw anti-loosening limiting components can clamp and limit the long shank screw. At the same time, a rubber clip is fixed to one end of the metal strip near the long shank screw. After the metal strip moves toward the long shank screw and deforms, the rubber clip clamps between the long shank screw and the metal strip, further enhancing the anti-loosening effect and providing double protection for the stable installation of aluminum profiles.
[0013] After the long-handled screw passes through the aluminum profile body and is fixed to the substrate, the metal strips on both sides of the long-handled screw can be clamped by hand pliers. The metal strips are stretched and deformed to clamp the long-handled screw, and the metal strips will not spring back. This secondary reinforcement method further prevents the long-handled screw from falling off, and further improves the safety and reliability of the aluminum profile installation.

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0016] Please see Figures 1-4 This utility model provides a technical solution: an aluminum profile with a screw limiting and anti-loosening structure, including an aluminum profile body 1, a long-shank screw 5 inserted into the surface of the aluminum profile body 1, and a reserved groove 101 integrally formed on each of the four side walls of the aluminum profile body 1. The reserved groove 101 is provided with a screw anti-loosening component. After the long-shank screw 5 penetrates the aluminum profile body 1, it squeezes one end of the screw anti-loosening component to produce elastic deformation. The screw anti-loosening component rebounds and supports the long-shank screw 5 to prevent it from being loosened. The surface of the reserved groove 101 is provided with a hole 102 for the long-shank screw 5 to be inserted. The screw anti-loosening limiting component includes a metal strip 2 and a rubber strip 3. The metal strip 2 has a "C"-shaped strip structure. The length of the metal strip 2 is equal to that of the aluminum profile body 1. A gap is left between one end of the metal strip 2 and the reserved groove 101. The rubber strip 3 is fixed in the gap between one end of the metal strip 2 and the reserved groove 101, and the length of the long side of the rubber strip 3 is equal to the length of the long side of the metal strip 2. After the long-shank screw 5 penetrates the aluminum profile body 1, one end of the long-shank screw 5 presses against the metal strips 2 and rubber strips 3 on both sides to cause deformation. The rubber strips 3 and metal strips 2 rebound and support one end of the long-shank screw 5 to move back. The long-shank screw 5 and the through hole of the aluminum profile body 1 are tightly engaged.
[0017] When installing the aluminum profile body 1 on the roof or other substrate, holes 102 are formed by drilling holes in the reserved groove 101 area between the two metal strips 2. The long shank screw 5 is passed through the hole 102 and screwed onto the substrate. As the long shank screw 5 is tightened, it is tightened until the end of the long shank screw 5 abuts against one end of the metal strip 2. The long shank screw 5 is then tightened, and the long shank screw 5 pushes forward, squeezing one end of the metal strip 2 to deform it and then squeezing the rubber strip 3. The rebound support of the metal strip 2 and the rubber strip 3 makes the long shank screw 5 tightly screwed together, thereby preventing the long shank screw 5 from falling off.
[0018] To improve the anti-loosening effect of the long shank screw 5, the following is proposed: Two sets of screw anti-loosening limiting components are provided, and the two sets of screw anti-loosening limiting components are distributed on both sides of the long shank screw 5. The two sets of screw anti-loosening limiting components are squeezed to clamp and limit the long shank screw 5. A rubber clip 4 is fixed to one end of the metal strip 2 near the long shank screw 5. The long side length of the rubber clip 4 is equal to the long side length of the metal strip 2. After the two metal strips 2 are clamped and moved towards the long shank screw 5 and deformed, the rubber clip 4 is clamped between the long shank screw 5 and the metal strip 2.
[0019] After the long-handled screw 5 passes through the aluminum profile body 1 and is fixed to the substrate, the metal strips 2 on both sides of the long-handled screw 5 are held by hand with pliers. After the metal strips 2 are stretched and deformed, they hold the long-handled screw 5. At this time, the metal strips 2 will not spring back, thus preventing the long-handled screw 5 from falling off.
[0020] Instructions for using aluminum profiles with screw-locking and anti-loosening structures: An aluminum profile with a screw-limiting and anti-loosening structure is prepared. The aluminum profile includes an aluminum profile body 1. Pre-formed grooves 101 are integrally formed on the four side walls of the aluminum profile body 1. Holes 102 for inserting long-shank screws 5 are opened on the surface of the pre-formed grooves 101. Screw anti-loosening components are installed inside the pre-formed grooves 101. Two sets of screw anti-loosening limiting components are provided, distributed on both sides of the long-shank screws 5. Each set of screw anti-loosening limiting components includes a metal strip 2 and a rubber strip 3. The metal strip 2 has a "C"-shaped structure. The length of the metal strip 2 is equal to that of the aluminum profile body 1. A gap is left between one end of the metal strip 2 and the pre-formed groove 101. The rubber strip 3 is fixed in this gap, and the length of the long side of the rubber strip 3 is equal to the length of the long side of the metal strip 2. A rubber clip 4 is fixed to the end of the metal strip 2 near the long-shank screw 5, and the length of the long side of the rubber clip 4 is equal to the length of the long side of the metal strip 2. Place the aluminum profile body 1 on the roof or other substrate. After determining the installation position, drill holes 102 in the reserved groove 101 area between the two metal strips 2. Pass the long-shank screw 5 through the hole 102 and screw it onto the substrate. Tighten the long-shank screw 5 until the end of the long-shank screw 5 abuts against one end of the metal strip 2. Continue to tighten the long-shank screw 5, which pushes one end of the metal strip 2 to deform it, thereby compressing the rubber strip 3. At this time, one end of the long-shank screw 5 simultaneously compresses the metal strips 2 and the rubber strip 3 on both sides, causing deformation. Since the rubber strip 3 and the metal strip 2 are elastic, they will rebound. When rebounding, the end supporting the long-shank screw 5 moves back, so that the long-shank screw 5 and the through hole of the aluminum profile body 1 are tightly engaged. At the same time, the rubber clip 4 clamps between the long-shank screw 5 and the metal strip 2 after the metal strip 2 is deformed. The two sets of screw anti-loosening limiting components clamp the long-shank screw 5 to limit it, further improving the anti-loosening effect. After the long-handled screw 5 passes through the aluminum profile body 1 and is fixed to the substrate, if it is necessary to further ensure that the long-handled screw 5 does not fall off, you can hold the metal strips 2 on both sides of the long-handled screw 5 with pliers, stretch and deform the metal strips 2 to make them clamp the long-handled screw 5. At this time, the metal strips 2 will not spring back, thereby preventing the long-handled screw 5 from falling off.
[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
