[0002] In fields such as electrical equipment installation and mechanical structure assembly, the fixed connection between guide rails and various components is a key link to ensure the stable operation of the system.

[0003] In the field of modern industrial assembly and electrical equipment installation, reliable connections between guide rails and components are fundamental to ensuring stable system operation. Traditional guide rail fixing methods mainly employ snap-fit ​​or direct bolt fastening structures. However, snap-fit ​​fasteners lack an active locking mechanism, making them prone to loosening or even detachment under equipment vibration and long-term load, threatening safe equipment operation. Traditional bolt fastening methods not only require pre-drilling holes in the guide rail, but the installation process is also cumbersome and time-consuming. Repeated disassembly and assembly can damage the guide rail, reducing connection strength and service life.

[0004] Therefore, a fastener is needed to solve this problem. Utility Model Content

[0005] To address the problems mentioned in the background art, the present invention aims to provide a fastener that features a unique snap-fit ​​design that uses a rotating bolt to drive the snap-fit ​​to rise and fall, thereby achieving efficient locking of the guide rail by the embedded groove and the sliding groove, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fastener, including a snap-fit ​​component for use with an external guide rail. The snap-fit ​​component has a snap-fit ​​groove at its bottom, and symmetrically arranged embedding grooves on both sides of the top of the snap-fit ​​groove, which snap into the two sides of the top of the guide rail. The snap-fit ​​component has a threaded opening at its top, and a sleeve frame is provided on the surface of the snap-fit ​​component. A sliding groove is provided at the bottom of the sleeve frame, and the sliding groove is slidably connected to the snap-fit ​​component. An operating groove is provided at the top of the sleeve frame, and a locking hole is provided at the bottom of the operating groove.

The top of the sliding groove is symmetrically fixedly connected with guide blocks, and the guide blocks are slidably connected to the guide openings.

[0008] As a preferred embodiment of this utility model, the top of the snap-fit ​​component is trapezoidal in shape, the bottom of the slide groove is trapezoidal in shape, and the top of the snap-fit ​​component and the bottom of the slide groove are used in conjunction.

[0009] As a preferred embodiment of this utility model, limit openings are provided on both sides of the sleeve frame, and limit blocks are fixedly connected to both ends of the snap-fit ​​component. The limit blocks are slidably connected to the limit openings, and triangular positioning blocks are fixedly connected to the walls of the limit openings.

[0021] 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.

[0022] like Figures 1 to 5 As shown, the present invention provides a fastener including a snap-fit ​​component 1 for use with an external guide rail. The snap-fit ​​component 1 has a snap-fit ​​groove 2 at its bottom and symmetrically arranged embedding grooves 3 on both sides of the top of the snap-fit ​​groove 2, which snap into the two sides of the top of the guide rail. The snap-fit ​​component 1 has a threaded opening 4 at its top. The snap-fit ​​component 1 has a sleeve frame 5 on its surface and a sliding groove 6 at its bottom, which slides with the snap-fit ​​component 1. The sleeve frame 5 has an operating groove 7 at its top and a locking hole 8 at the bottom of the operating groove 7. A bolt 9 is threaded into the locking hole 8, and the bottom of the bolt 9 is threaded into the threaded opening 4. The sleeve frame 5 has three irregularly shaped recesses 10 symmetrically arranged on its front and back sides, which are used to mate with external connectors.

[0023] refer to Figure 2 , Figure 4 and Figure 5 The top of the snap-fit ​​1 is symmetrically provided with guide openings 11, and the guide openings 11 are connected to the embedded groove 3. The top of the sliding groove 6 is symmetrically fixedly connected with guide blocks 12, and the guide blocks 12 are slidably connected to the guide openings 11.

[0024] As a technical optimization of this utility model, the sliding cooperation between the guide block 12 and the guide port 11 provides precise guidance for the lifting and lowering of the snap-fit ​​1, preventing the snap-fit ​​1 from tilting or jamming during movement, ensuring a smooth installation process. At the same time, the guide structure can disperse the lateral force generated when the bolt 9 rotates, enhance the linkage stability between the snap-fit ​​1 and the sleeve 5, and improve the overall structural strength.

[0025] refer to Figure 3 The top of the snap-fit ​​1 is trapezoidal, the bottom of the slide 6 is trapezoidal, and the top of the snap-fit ​​1 and the bottom of the slide 6 are used together.

[0026] As a technical optimization of this utility model, the trapezoidal structure transmits lifting force through inclined contact, which can increase the contact area and reduce local wear. Then, the self-locking characteristic of the inclined surface is used to improve the anti-vibration performance after locking, and prevent the bolt 9 from loosening and causing fixing failure. At the same time, the trapezoidal surface cooperation can make the snap-fit ​​1 bear force evenly during the lifting process, avoid single-point stress concentration, and extend the service life of the component.

[0027] refer to Figure 1 and Figure 2 Limiting openings 13 are provided on both sides of the frame 5. Limiting blocks 14 are fixedly connected to both ends of the snap-fit ​​1, and the limiting blocks 14 are slidably connected to the limiting openings 13. A triangular positioning block 15 is fixedly connected to the opening wall of the limiting opening 13, and the triangular positioning block 15 and the limiting block 14 are used together.

[0028] As a technical optimization of this utility model, the lateral movement range of the snap-fit ​​part 1 is limited by the limiting block 14 and the limiting port 13 to prevent it from falling off the sleeve frame 5. Then, through the cooperation of the triangular positioning block 15 and the limiting block 14, clear positioning feedback can be provided when the snap-fit ​​part 1 is in place, ensuring that the embedded groove 3 is accurately aligned with the guide rail. Furthermore, the rigid structure of the triangular positioning block 15 can limit the displacement of the snap-fit ​​part 1 under vibration or impact conditions, thereby enhancing the dynamic load resistance of the fixing part.

[0029] refer to Figure 1 and Figure 3 The front and back of the frame 5 are symmetrically provided with mesh-like reinforcing grooves 16.

[0030] As a technical optimization of this utility model, the mesh reinforcing groove 16 optimizes the cross-sectional structure of the sleeve frame 5, thereby reducing the amount of material used and improving the overall rigidity. This prevents the sleeve frame 5 from deforming when the bolts 9 are tightened, ensuring the reliability of force transmission. In addition, the mesh structure can increase the surface area of ​​the sleeve frame 5, which can help dissipate local heat in electrical equipment application scenarios and improve system durability.

[0031] refer to Figure 1 and Figure 3 The side walls on both sides of the frame 5 are symmetrically provided with snap-in slots, which are used in conjunction with external cables.

[0032] As a technical optimization of this utility model, the slot provides a dedicated fixing position for peripheral cables, avoiding interference between cables and guide rails or other components, improving the neatness and safety of wiring, and is especially suitable for scenarios with dense cables such as electrical cabinets. In addition, the shape of the slot can form an elastic clamp for the cable, preventing the cable from loosening due to vibration or external pulling, and enhancing the reliability of the system.

[0033] The working principle and usage process of this utility model are as follows: First, when using this fastener, slide the snap-fit ​​1 into the slide groove 6 of the sleeve frame 5, so that the limiting blocks 14 on both sides of the snap-fit ​​1 are engaged in the limiting openings 13 of the sleeve frame 5. Then, tighten the bolt 9 to the top of the locking hole 8, without deeply engaging with the threaded opening 4, and the embedded groove 3 is not in contact with the top of the guide rail. Then, align the snap-fit ​​groove 2 of the snap-fit ​​1 with the top of the guide rail, so that the two sides of the top of the guide rail are aligned with the position of the embedded groove 3. Next, use an external tool to tighten the bolt 9 in the operating groove 7, so that it is screwed down into the threaded opening 4 along the locking hole 8. Due to the thread transmission between the bolt 9 and the threaded opening 4, the snap-fit ​​1 descends with the bolt 9 and slides down along the slide groove 6. At the same time, the guide block 12 slides in the guide opening 11 to ensure that the snap-fit ​​1 descends vertically and avoids deviation. When the snap-fit ​​1 descends to the point where the embedded groove 3 contacts the two sides of the top of the guide rail, stop tightening the bolt 9. At this time, the two sides of the top of the guide rail are engaged in the embedded groove 3, completing the initial positioning. Then reverse... Rotate the bolt 9 upwards. Due to the threaded drive, the snap-fit ​​1 moves upwards along the slide groove 6. At this time, the trapezoidal structure at the top of the snap-fit ​​1 cooperates with the trapezoidal structure at the bottom of the slide groove 6 to form a wedge-tightening effect, causing the embedded groove 3 to press upwards against the top two sides of the guide rail. The limiting block 14 slides within the limiting port 13. When the limiting block 14 contacts the triangular positioning block 15, a mechanical limit is formed, ensuring that the snap-fit ​​1 rises to the preset locking position. At this time, the embedded groove 3 and the bottom of the slide groove 6 clamp the guide rail together, thereby achieving locking. Finally, it is snapped with the external busbar through the concave points 10 on the front and back of the sleeve frame 5. The special structure of the concave points 10 is used to achieve electrical connection or mechanical fixation. The external cable is fixed through the snap-fit ​​grooves on both sides of the sleeve frame 5. The groove structure is used to limit the displacement of the cable. When it is necessary to remove the fixing part, turn the bolt 9 to lower it, causing the snap-fit ​​1 to move downwards, releasing the compression of the embedded groove 3 on the guide rail. When the embedded groove 3 is completely separated from the guide rail, the fixing part can be removed from the guide rail.
