Description

Technical Field

[0001] This utility model relates to the field of buckle technology, and in particular to a fish-shaped detachable anti-loosening buckle. Background Technology

[0002] In furniture manufacturing, building decoration, and home furnishing assembly, the performance of connectors directly affects the stability and lifespan of products. A fish-shaped detachable anti-loosening buckle, as a new type of connection device, was developed based on the higher requirements placed on connectors by modern prefabricated structures. With the popularization of modular design concepts and users' increasing demands for product quality, traditional connection methods are no longer sufficient to meet the core needs of convenient assembly and disassembly and long-term anti-loosening in cross-industry applications.

[0003] In existing technologies, furniture connections mainly employ threaded fasteners, snap-fit ​​connections, or adhesive bonding. Threaded connections typically use screws and nuts, relying on the friction of the threads for fixation; snap-fit ​​connections utilize the elastic deformation of plastic parts to achieve engagement; some high-end products use metal connectors in conjunction with adhesives.

[0004] However, the main problem with existing technologies is that connectors are prone to loosening during use, especially under prolonged vibration or frequent disassembly and assembly. The anti-loosening performance of traditional structures is clearly insufficient, seriously affecting the stability and lifespan of furniture. This problem is particularly prominent during furniture transportation, daily use, and repeated disassembly and assembly. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fish-shaped detachable anti-loosening buckle, which aims to improve the problem of loosening that easily occurs in existing connectors during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fish-shaped detachable anti-loosening buckle, comprising:

[0007] Fish-shaped buckle, rubber sleeve fitted on the outside of the screw rod, screw rod that mates with the fish-shaped buckle, and rubber nut head that mates with the screw rod;

[0008] The fish-shaped buckle has a cylindrical structure with openings on both sides and an expansion joint, and a three-pronged elastic buckle at the head.

[0009] The nut of the screw rod can be held tightly by a three-jaw elastic buckle to form a mechanical interlock;

[0010] The rubber sleeve is used to enhance connection saturation and anti-loosening performance;

[0011] The rubber nut head is used to further tighten the connection structure.

[0012] Furthermore, the openings on both sides of the fish-shaped buckle are used to embed connecting components to prevent slippage.

[0013] Furthermore, the three-pronged elastic buckle can be pried open by external force to loosen the nut on the screw rod.

[0014] Furthermore, the rubber sleeve is made of elastic material, and the rubber nut head is formed by injection molding.

[0015] Furthermore, the fish-shaped buckle is made of metal.

[0016] Furthermore, the nut of the screw rod has a round head structure.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the fish-shaped buckle's three-claw elastic buckle structure forms a mechanical interlock with the screw rod. Combined with the elastic wrapping of the rubber sleeve and the secondary locking of the rubber nut head, a multi-layer anti-loosening mechanism is constructed. This not only solves the problems of easy loosening and poor stability of traditional furniture connectors, but also makes the detachable structure easier for furniture assembly, adjustment and maintenance, significantly improving the service life and user experience of furniture products.

[0019] 2. In this utility model, the connection structure is particularly suitable for furniture connection and various hanging parts installation. Its anti-loosening performance can ensure that the furniture will not loosen during long-term use. The detachable design facilitates furniture disassembly, assembly, and transportation. At the same time, the structure is simple and reliable, and the production cost is low. It can be widely used for the connection and fixing of various home furnishing products such as panel furniture, modular furniture, and wall hanging parts. Attached Figure Description

[0025] 1. Fish-shaped buckle; 2. Rubber sleeve; 3. Screw rod; 4. Rubber nut head. Detailed Implementation

[0026] 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.

[0027] Reference Figures 1-4 One embodiment of this utility model is a fish-shaped detachable anti-loosening buckle, comprising:

[0028] Fish-shaped buckle 1, rubber sleeve 2 sleeved on the outside of screw rod 3, screw rod 3 that cooperates with fish-shaped buckle 1, and rubber nut head 4 that cooperates with screw rod 3. The strip-shaped openings on both sides can effectively prevent the connecting parts from circumferential displacement during use. The specially designed three-claw elastic buckle at the head can deform and reliably hold the nut when the screw rod 3 is inserted through the opening angle and elastic modulus, so as to achieve a stable mechanical interlocking connection.

[0029] The fish-shaped buckle 1 adopts a cylindrical structure with openings on both sides and an expansion joint, and a three-pronged elastic buckle at the head.

[0030] The nut of screw rod 3 can be held by the three-jaw elastic buckle to form a mechanical interlock. Its round or hexagonal head structure can form the best fit with the three-jaw buckle. As the main force-bearing component, it not only bears the axial tensile force but also transmits the torque, ensuring the overall strength and reliability of the connection structure.

[0031] The rubber sleeve 2 is used to enhance the connection saturation and anti-loosening performance. It is tightly fitted on the outside of the fish-shaped buckle 1. Through its elastic properties, it eliminates assembly gaps, increases the contact area and friction of the connection interface, and absorbs vibration energy by utilizing the damping properties of polymer materials, significantly improving the anti-loosening performance and effectively buffering external impact.

[0032] The rubber nut head 4 is used to further tighten the connection structure. The openings on both sides of the fish-shaped buckle 1 are used to embed the connecting parts to prevent slippage. The three-pronged elastic buckle can be pried open by external force to loosen the nut of the screw rod 3. The rubber sleeve 2 is made of elastic material. The rubber nut head 4 is molded by injection molding. The fish-shaped buckle 1 is made of metal material. The nut of the screw rod 3 has a round head structure. The internal thread is precisely matched with the screw rod 3, which is convenient for manual or tool operation. Its engineering plastic material ensures sufficient strength and has a certain degree of elasticity, realizing the secondary locking function and further improving the connection stability and sealing.

[0033] Specifically, the fish-shaped buckle 1 adopts a cylindrical structure design with symmetrical strip-shaped openings on both sides to prevent circumferential sliding. The three-pronged elastic buckle at the head undergoes elastic deformation when the screw rod 3 is inserted through a precisely designed angle, firmly gripping the nut to form a mechanical interlock. The rubber sleeve 2 is made of highly elastic rubber material and is tightly fitted to the outside of the buckle. It eliminates assembly gaps through elastic deformation and absorbs vibration through damping characteristics, significantly improving the anti-loosening performance. The rubber nut head 4 is injection molded from engineering plastic and precisely matches the screw rod 3 to further lock the structure and compensate for dimensional tolerances. During assembly, the screw rod 3 is inserted axially, causing the three-pronged buckle to elastically deform and then spring back to lock. At the same time, the rubber sleeve 2 undergoes radial deformation to achieve wrapping reinforcement. During disassembly, the three-pronged buckle can be released by prying it from the side.

[0034] Working principle: When the fish-shaped detachable anti-loosening buckle is needed, the fish-shaped buckle 1 adopts a cylindrical design with holes on both sides to prevent slippage. At the same time, it has an expansion joint, which makes it easy for the fish-shaped buckle 1 to be installed in the mounting hole. After installation, the expansion joint gives the fish-shaped buckle 1 tension, which, like the holes on both sides, plays a fixing role. Its head three-prong elastic buckle holds the nut of the screw rod 3 to form a mechanical interlock. The rubber sleeve 2 enhances the connection saturation and anti-loosening performance, and the rubber nut head 4 further tightens and improves the overall stability. When connecting, the screw rod 3 is inserted into the fish-shaped buckle 1, the three-prong buckle is elastically engaged, and the rubber sleeve 2 wraps and reinforces it. When disassembling, the nut can be loosened by prying open the three-prong buckle, realizing quick disassembly and assembly. This structure is simple and reliable, and has the characteristics of anti-loosening, detachability and strong adaptability. It is suitable for connection scenarios that require shock protection or frequent disassembly and assembly.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
