Description

Technical Field

[0001] This utility model relates to the field of plastic buckle technology, and in particular to a plastic buckle with a built-in anti-loosening bolt. Background Technology

[0002] Plastic clips are fasteners that utilize the elastic deformation of engineering plastics to achieve rapid assembly, enabling tool-free instant fixation. These clips offer advantages such as lightweight, low cost, corrosion resistance, and vibration and noise reduction. They are widely used in automotive interiors, appliance housings, consumer electronics, and other fields sensitive to assembly efficiency and weight. They are mainly used for connecting cover parts or lightweight components. Among them, plastic clips with built-in anti-loosening bolts are composite fasteners. They integrate a metal bolt with an anti-loosening structure (such as a nylon locking ring or pre-applied adhesive) in the center of a traditional plastic clip base through an insert injection molding process.

[0003] However, in existing technologies, the design of the snap-fit ​​mechanism is flawed, resulting in unclear tactile feedback, difficulty in snapping in, or abnormal noise during initial installation, severely slowing down the assembly process and reducing production efficiency. Furthermore, if there are gaps or loosening between the snap-fit ​​and the mounting plate after pre-fixing, it will not only make subsequent bolt tightening difficult, but also, under vibration, the unstable foundation will prevent the final anti-loosening bolts from forming a uniform and reliable clamping force, reducing practical efficiency.

[0004] Therefore, this application provides a plastic clip with a built-in anti-loosening bolt to meet the requirements. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the above-mentioned background technology that it is not more convenient and stable when snapping, and not more secure when snapping, and to propose a plastic snap with a built-in anti-loosening bolt.

[0006] The technical problem to be solved by this utility model is to provide a plastic clip with a built-in anti-loosening bolt to solve the problem of existing plastic clips with built-in anti-loosening bolts.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a fastener is included, wherein a snap-fit ​​assembly is provided inside the fastener, the snap-fit ​​assembly includes an elastic plate, a contact head and a rounded corner, one side of the elastic plate is fixedly installed to one side of the inner wall of the fastener, the front and back sides of the contact head are fixedly installed, and the rounded corner is provided at one end of the right side of the contact head.

[0008] Preferably, the fastener has a snap-fit ​​groove inside, and a snap-fit ​​block is snapped into the snap-fit ​​groove. The left end of the snap-fit ​​block is provided with a second rounded corner, and after the second rounded corner abuts against the first rounded corner, the elastic plate can be pressed down, so that the snap-fit ​​groove slides into the interior of the fastener.

[0009] Preferably, the front of the card block has a card slot, which follows the card block into the interior of the fastener and engages with the rounded corner.

[0010] Preferably, the other side of the contact head is also provided with a rounded corner for separation between the card block and the fastener, and the shape and size of the contact head are the same as the internal shape and size of the card slot.

[0011] Preferably, a pushing groove is provided on the right side of the card block, and anti-slip protrusions are evenly distributed on the right side of the pushing groove. The anti-slip protrusions are used to prevent slippage when the card block is pushed into the fastener.

[0012] Preferably, the fastener has a threaded groove inside, a screw is rotatably mounted on the inner wall of the threaded groove, and a nut is fixedly mounted on one end of the screw.

[0013] Preferably, the inner wall of the card block is provided with a second threaded groove, and the shape and size of the second threaded groove are the same as those of the first threaded groove. The inner wall of the second threaded groove is rotatably mounted to the outer surface of the screw.

[0014] Preferably, the internal size of the snap-fit ​​groove is the same as the width of the left side of the snap-fit ​​block, and the internal size of the snap-fit ​​groove is larger than the narrow width of the right side of the snap-fit ​​block.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects: In the above scheme, the elastic plate is guided to undergo elastic deformation by the cooperation of the beveled surfaces of rounded corner two and rounded corner one, so that the locking block can slide in smoothly. The assembly process is simple and labor-saving. When the locking groove and the contact head are aligned, the rebound characteristics of the elastic plate are used to make the contact head accurately lock into the locking groove, which can achieve the effect of preventing loosening. The structure with rounded corner one on both sides of the contact head makes it easy to press down the elastic plate again to separate during disassembly, realizing a convenient disassembly function. In this way, the overall structure combines the quick connection of the snap-fit ​​and the reliability of the bolt anti-loosening, improving the vibration resistance and long-term stability of the connection point.

[0016] In the above solution, a powerful secondary mechanical locking force is generated by rotating the nut to drive the screw in, providing double protection for connection stability. The combination design of the push groove and anti-slip convex plate significantly improves the assembly operability. By increasing the contact area and friction coefficient of the pushing torque, it is ensured that the locking block can be pushed into the fastener smoothly, effortlessly and accurately, effectively avoiding slippage during operation.

[0023] Please see Figure 3 and Figure 4A plastic clip with a built-in anti-loosening bolt includes a fastener 1. The fastener 1 has a clip assembly 6 inside. The clip assembly 6 includes an elastic plate 601, a contact head 602, and a rounded corner 603. One side of the elastic plate 601 is fixedly installed to one side of the inner wall of the fastener 1. The front and back sides of the contact head 602 are fixedly installed. The rounded corner 603 is located at one end of the right side of the contact head 602. The fastener 1 has a locking groove 2 inside, and a locking block 7 is engaged inside the locking groove 2. The left end is provided with a rounded corner 604, and after the rounded corner 604 abuts against the rounded corner 603, the elastic plate 601 can be pressed down, so that the snap-fit ​​groove 2 slides into the interior of the fastener 1. The front of the snap-fit ​​block 7 is provided with a snap-fit ​​groove 605. After the snap-fit ​​groove 605 follows the snap-fit ​​block 7 into the interior of the fastener 1, it snaps against the rounded corner 603. The other side of the contact head 602 is also provided with a rounded corner 603 for separating the snap-fit ​​block 7 from the fastener 1. The shape and size of the contact head 602 are the same as the internal shape and size of the snap-fit ​​groove 605.

[0024] Specifically, through the cooperative design of the elastic plate 601 and the rounded corner 603 on the contact head 602 in the snap-fit ​​assembly 6, the rounded corner 604 on the snap-fit ​​block 7, and the snap-fit ​​groove 605, a relatively stable connection structure can be formed after the snap-fit ​​block 7 and the fastener 1 are snapped together. This effectively prevents the bolts from loosening and improves the reliability of the connection. The elastic plate 601 is pressed down by the abutment of the rounded corner 603 and the rounded corner 604, realizing the snap-fit ​​and separation operation between the snap-fit ​​block 7 and the fastener 1. No complicated tools or cumbersome steps are required, which is convenient and quick and improves work efficiency. The overall structure consists of several main parts such as the fastener 1, the snap-fit ​​assembly 6, and the snap-fit ​​block 7. The connection and cooperation relationship between each component is clear and easy to manufacture and process, reducing production costs.

[0025] Please see Figure 1 , Figure 2 and Figure 4 The right side of the locking block 7 is provided with a pushing groove 8, and anti-slip protrusions 9 are evenly distributed on the right side of the pushing groove 8. The anti-slip protrusions 9 are used to prevent slippage when the locking block 7 is pushed into the fastener 1. The fastener 1 is provided with a threaded groove 3. A screw 4 is rotatably installed on the inner wall of the threaded groove 3. A nut 5 is fixedly installed on one end of the screw 4. The inner wall of the locking block 7 is provided with a threaded groove 10. The shape and size of the threaded groove 10 are the same as those of the threaded groove 3. The inner wall of the threaded groove 10 is rotatably installed on the outer surface of the screw 4. The size of the locking groove 2 is the same as the size of the left wide part of the locking block 7. The size of the locking groove 2 is larger than the size of the right narrow part of the locking block 7.

[0026] Specifically, the design of the push groove 8 and the anti-slip protrusion 9 allows operators to easily push the locking block 7 into the fastener 1 without slipping during the pushing process. The movement of the locking block 7 is controlled by rotating the nut 5 to drive the screw 4, enabling quick installation and removal of the locking block 7 and the fastener 1 without the need for complex tools or cumbersome steps, thus improving work efficiency. The design of the locking groove 2, whose internal size is the same as the width of the left side of the locking block 7 and larger than the narrow side of the right side, ensures stable locking of the locking block 7 within the locking groove 2, preventing wobbling or displacement. The precise fit between the screw 4 and the threaded grooves 3 and 10 also ensures the stability of the entire structure under stress, enhancing its overall strength and stability.

[0027] Working principle: During use and assembly, external force pushes the locking block 7, causing it to contact the inclined surface of the rounded corner 604 of the fastener 1's internal snap-fit ​​assembly 6. This forces the elastic plate 601 to undergo elastic deformation and press down, allowing the locking block 7 to slide smoothly into the snap-fit ​​groove 2 inside the fastener 1. When the locking block 7 continues to move until its groove 605 aligns with the rounded corner 603, the elastic plate 601 rebounds, driving the contact head 602 to snap into the groove 605, forming a mechanical interlock. This achieves the initial fastening of the locking block 7 and the fastener 1. Finally, by rotating the nut 5, the screw 4 is screwed into the threaded groove 10, generating a strong axial clamping force between the locking block 7 and the fastener 1. The self-locking characteristic achieves a reliable anti-loosening effect.
