Description
Technical Field
[0001] The utility model relates to the technical field of connecting and fixing components, and in particular to a universal wiring harness or pipeline fixing structure. Background Art
[0002] Wire harness and pipe fixtures are key components to ensure the normal operation of the vehicle's electrical and fluid systems. These devices can effectively fix the wire harness and pipes to various parts of the vehicle to prevent them from being damaged by vibration, friction or collision, while also helping to improve the layout aesthetics and safety and reliability of the vehicle.
[0003] After searching, the Chinese patent with announcement number: CN203067935U discloses a fixing device that can adapt to the secure connection and fixation of wire harnesses or pipelines to sheet metal parts at various angles, which overcomes the shortcomings of existing wire harness or pipeline fixing devices that cannot achieve secure fixation of wire harnesses or pipelines at various angles when fixing wire harnesses or pipelines to sheet metal parts. The wire harness or pipeline fixing device described includes a main body, and the main body is provided with a fixing chuck and a perforated buckle. The fixing chuck and the perforated buckle are arranged on both sides of the main body. The perforated buckle includes a plurality of spring pieces and a main rod. The distance between the spring piece and the main rod increases from the direction away from the main body to the direction close to the main body, and the fixing chuck is U-shaped. The utility model is suitable for occasions where previous wire harness or pipeline fixing devices are applicable, and has the advantages of being able to achieve the connection and fixation of wire harnesses or pipelines to sheet metal parts at various angles.
[0004] The existing devices have some disadvantages during use. For example, the method of connecting and fixing with cable ties is currently more commonly used, that is, putting the wire harness or pipeline together with the sheet metal part, and then tying it tightly with cable ties. However, in actual use, some problems may occur when tying the cable ties at certain positions on the sheet metal part. For example, when the contact point between the sheet metal part and the cable tie is a bevel rather than a regular plane, it will cause the cable tie to be difficult to tighten and easy to slip. Therefore, this method cannot fully meet the fixation of the wire harness or pipeline at various angles. Utility Model Content
[0005] The purpose of the utility model is to provide a universal wiring harness or pipeline fixing structure to solve the problem that when the contact point between the sheet metal and the cable tie is an oblique edge rather than a regular plane, it will cause the cable tie to be difficult to tighten and easy to slip. Therefore, this method cannot fully meet the problem of fixing the wiring harness or pipeline at various angles.

[0015] In the above solution, the sliding of the guide block in the guide groove not only ensures the stability of the movement of the upper clamping ring, but also makes the adjustment process smoother and more labor-saving.
[0016] As a preferred embodiment of the above technical solution, a filling protection block is fixedly connected to the inner walls of the lower clamping ring and the upper clamping ring, and the filling protection block is an arc-shaped structure.
[0017] In the above scheme, the arc-shaped filling protection block can better adapt to the curved shape of the wire harness or pipeline, and can achieve uniform and stable clamping regardless of whether it is a straight section or a curved section.
[0018] As a preferred embodiment of the above technical solution, a through hole is provided at the connection between the upper clamping ring and the lower clamping ring.

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example
[0028] like Figure 1 and Figure 4 As shown, the utility model provides a technical solution: a universal wiring harness or pipeline fixing structure, including a screw 10, a plurality of openings 11 are annularly opened on the outer wall of the screw 10, a restraining mechanism for assisting the screw 10 in fixing is arranged at the top of the screw 10, a clamping and fixing mechanism for bundling the wiring harness or pipeline is arranged at the top of the restraining mechanism, the clamping and fixing mechanism and the screw 10 are detachably fixed, and during specific use, the screw 10 is fixed to the area to be fixed, the opening 11 of the screw 10 can increase the grip of the thread, thereby improving the fastening effect, preventing the screw 10 from sliding or loosening when subjected to force, and improving the safety of use, the design of the restraining mechanism can assist the fixation of the screw 10, ensure that the screw 10 is more stable in the fixed area, and the wiring harness or pipeline can be conveniently bundled by the provided clamping and fixing mechanism, the detachable fixing design between the clamping and fixing mechanism and the screw 10 makes this fixing structure have greater flexibility, and in actual use, the clamping and fixing mechanism can be replaced or adjusted at any time as needed to meet the fixing requirements of different wiring harnesses or pipelines.
[0029] As an implementation method in this embodiment, Figure 3 As shown, the restraining mechanism includes a lower elastic disk 20 and an upper elastic disk 21, and the lower elastic disk 20 and the upper elastic disk 21 are both sleeved and fixed on the outer wall of the top of the screw 10, and a diaphragm spring 22 is fixedly connected between the upper elastic disk 21 and the lower elastic disk 20. During specific use, the lower elastic disk 20 and the upper elastic disk 21 are both made of elastic material (such as rubber), which enables them to generate corresponding elastic force when compressed or stretched. When the screw 10 is fixed to the wall, the lower elastic disk 20 will contact the wall and generate a certain compression. Due to the characteristics of the elastic material, the lower elastic disk 20 will generate a backward pulling force, which is transmitted to the upper elastic disk 21 through the diaphragm spring 22, thereby forming a stable restraining force. This restraining force can effectively prevent the screw 10 from shaking left and right when subjected to force, thereby enhancing the stability and safety of the fixation.
[0030] As an implementation method in this embodiment, Figure 1As shown, the clamping and fixing mechanism includes a chassis 30, the upper end surface of the chassis 30 is fixedly connected to a lower clamping ring 31, one end of the lower clamping ring 31 is fixedly connected to an upper clamping ring 32, the end of the lower clamping ring 31 away from the upper clamping ring 32 is fixedly connected to a clamping protrusion 33, and the inner wall of the end of the upper clamping ring 32 away from the lower clamping ring 31 is provided with a clamping groove 34 adapted to the clamping protrusion 33. In specific use, the lower clamping ring 31 and the upper clamping ring 32 together constitute the main body of the clamping, and the upper clamping ring 32 can be adjusted by adjusting the clamping ring 32. The position relative to the lower clamping ring 31 can adapt to wire harnesses or pipelines of different thicknesses to ensure the tightness and stability of the clamping. In addition, a clamping protrusion 33 is provided at the end of the lower clamping ring 31 away from the upper clamping ring 32, and a clamping groove 34 is provided on the inner wall of the end of the upper clamping ring 32 away from the lower clamping ring 31. When it is necessary to fix the upper clamping ring 32 and the lower clamping ring 31 together, it is only necessary to align the clamping protrusion 33 with the clamping groove 34 and insert it to achieve a quick connection between the two, thereby improving the stability and reliability of the clamping.
[0031] As an implementation method in this embodiment, Figure 2 As shown, a through hole 301 is provided at the center of the chassis 30, a mounting hole 311 is provided at the middle end of the lower clamping ring 31, a threaded hole 101 is provided at the top end of the screw 10, and bolts 40 are inserted into the inner sides of the through hole 301, the mounting hole 311 and the threaded hole 101. The chassis 30 is detachably fixed to the screw 10 by the bolt 40. During specific use, the through hole 301 at the center of the chassis 30, the mounting hole 311 at the middle end of the lower clamping ring 31, and the threaded hole 101 at the top end of the screw 10 together constitute an aligned connection channel, so that the bolt 40 can smoothly pass through these holes, thereby realizing the connection between the various components. When the bolt 40 fixes the various components, the upper clamping ring 32 is in an open state.
[0032] As an implementation method in this embodiment, Figure 1 As shown, a guide plate 50 is fixedly connected to one side of the upper end surface of the chassis 30, a guide groove 51 is opened at the end of the guide plate 50, and a guide block 52 adapted to the guide groove 51 is fixedly connected to the outer wall of the end of the upper clamping ring 32. During specific use, the guide groove 51 opened at the end of the guide plate 50 plays a guiding and positioning role. When the position of the upper clamping ring 32 needs to be adjusted, the guide groove 51 can ensure that the upper clamping ring 32 moves along a predetermined path to avoid offset or misalignment.
[0033] As an implementation method in this embodiment, Figure 1As shown, a filling protection block 60 is fixedly connected to the inner wall of the lower clamping ring 31 and the upper clamping ring 32. The filling protection block 60 is an arc-shaped structure. The existence of the filling protection block 60 enables the lower clamping ring 31 and the upper clamping ring 32 to fit more closely to the surface when clamping the wiring harness or pipeline. This close fit not only reduces the risk of falling off due to shaking, but also enhances the stability of clamping, ensuring that the wiring harness or pipeline will not move in a fixed position. In addition, the filling protection block 60 is made of a soft material (such as rubber or elastic plastic). They can buffer the clamping force during the clamping process to prevent the surface of the wiring harness or pipeline from being clamped or scratched, which is especially important for wiring harnesses or pipelines that need to be fixed for a long time and whose surfaces are easily damaged.
[0034] As an implementation method in this embodiment, Figure 1 As shown, a through hole 70 is provided at the connection between the upper clamping ring 32 and the lower clamping ring 31. The existence of the through hole 70 reduces the solid part of the clamping ring, so that the upper clamping ring 32 is easier to bend. The upper clamping ring 32 and the lower clamping ring 31 can be made of rubber or elastic plastic.
[0035] Working principle: First, fix the screw 10 to the area to be fixed. The opening 11 of the screw 10 can increase the grip of the thread, thereby improving the fastening effect and preventing the screw 10 from sliding or loosening when subjected to force. Then, the chassis 30 is detachably fixed to the screw 10 by bolts 40. By adjusting the position of the upper clamping ring 32 relative to the lower clamping ring 31, it can adapt to wire harnesses or pipelines of different thicknesses to ensure the tightness and stability of the clamping. In addition, a clamping protrusion 33 is provided at the end of the lower clamping ring 31 away from the upper clamping ring 32, and a groove 34 is provided on the inner wall of the end of the upper clamping ring 32 away from the lower clamping ring 31. When the upper clamping ring 32 and the lower clamping ring 31 need to be fixed together, just align the clamping protrusion 33 with the groove 34 and insert it to achieve a quick connection between the two.
[0036] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
