Description

Technical Field

[0001] This invention relates to the field of wire harness fixing technology, and in particular to a wire harness frame fixing device. Background Technology

[0002] A wiring harness is a group of metal components bound together with electrical circuitry, serving as a connection for signals and power between devices. It is a wiring component in automotive circuitry that connects various electrical devices.

[0003] However, traditional wire harness frames use clamps to fix the wire harness one by one. This process requires adjusting the position of each clamp to accommodate the curvature of the wire harness, which is relatively cumbersome. If a fixed structure is used to fix the wire harness, it is difficult to adapt to curved wire harnesses. When using a fixing bracket to fix the wire harness, the spring clamp method is prone to loosening, resulting in poor fixing effect. The wire harnesses have different heights, and it is difficult to adjust the fixing device to accommodate wire harnesses of different heights. Summary of the Invention

[0004] In view of this, the present invention provides a fixing device for a wire harness frame, which has a connector that can connect multiple sets of support bases and can also change the bending angle to adapt to the fixing of wire harnesses with different degrees of bending.

The linkage includes a toothed rod, a pushing block, and a fixing rod, wherein the toothed rod penetrates the base, and the fixing rod is fixed and vertically connected to the top surface of the base. The first transmission gear is movably connected to the top surface of the base via a shaft.

The second transmission gear is movably connected to the top surface of the base via a shaft. The clamping member consists of a fixing ring, a rotating tube, a sliding plate, a clamping block, and a stop block. The fixing ring is fixedly connected to the top surface of the base via a rod, and the stop block is fixedly installed on the top surface of the base via a vertical rod. The connector includes a fixing tube, a snap ring, a torsion ring, and a threaded rod. The fixing tube is fixedly connected to the side of the base, and the threaded rod is threadedly engaged inside the fixing tube.

The outer end face of the strap is a pull strap, and the bottom end of the pull strap is fixedly connected to the connecting frame, which passes through the support base.

[0008] Optionally, the toothed rod has an insertion hole at its lower interior, into which a connecting frame is inserted. A wedge plate is fixedly installed on the upper part of the toothed rod. The inner side of the push block has a wedge structure, and the inclined surface of the wedge structure fits against the inclined surface of the wedge plate on the toothed rod. The outer end of the push block is connected to the upper part of the fixed rod through a spring and a telescopic sleeve. A rectangular rod is fixedly installed on the inner side of the push block, and the end of the rectangular rod is engaged inside the rotating plate.

[0009] Optionally, two sets of rings are fixedly installed on the lifting rod, and the two sets of rings abut against the upper and lower surfaces of the rotating plate respectively. The rotating plate has a circular hole inside, through which a wire harness passes.

[0010] Optionally, the fixed retaining ring has a movable retaining tube inside, the outside of the retaining tube is provided with teeth, the teeth are meshed with the second transmission gear, the inside of the retaining tube is provided with a threaded rod through threaded engagement, the threaded rod is fixedly connected to the inside of the slide plate, and the clamping block is fixedly connected to the slide plate through a bolt assembly, the height of the clamping block and the abutment block correspond to each other.

[0011] Optionally, the outer sleeve of the fixed tube is fitted with a snap ring, and the upper part of the snap ring is provided with a through groove, through which a torsion ring passes, and the threaded rod is connected to the inside of the fixed tube by thread engagement. Beneficial effects

[0012] 1. Compared with traditional fixing devices, this invention connects two sets of fixing tubes through a threaded rod, making the two sets of support bases a single unit. Rotating the torsion ring causes the locking ring to rotate, changing the shape of the fixing tube. This allows adjustment of the connection angle between adjacent sets of support bases, enabling adjustments based on the curvature of the wire harness when multiple sets of support bases are connected, thus improving adaptability.

[0013] 2. After the second transmission gear is driven to rotate by the pull rod, it drives the rotating tube to rotate. The rotating tube drives the threaded rod to move through the threaded engagement, which in turn drives the slide plate to slide in the direction of the slide groove, changing the distance between the clamping block and the abutment block. Adjusting the clamping force between the clamping block and the abutment block achieves the fixing of the wire harness. After the adjustment is completed, the pull rod is bent to prevent it from moving back, thereby fixing the position of the pull rod. The connecting bracket is bent to fix it to the outside of the support base, thereby fixing the position of the toothed rod and achieving the fixing of the wire harness.

[0014] 3. Pulling the connecting frame up and down moves the strap up and down, thus adjusting the tension of the strap. When the pull rod is pulled, the first transmission gear is driven to rotate through the toothed groove, which in turn moves the slider to change the position of the strap, adjusting the tension and position of the strap. The toothed rod drives the first transmission gear to rotate through meshing, and the first transmission gear drives the lifting rod to move up and down, thereby adjusting the height of the rotating plate to meet the constraints of the wire harness position.

[0019] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0020] Example: Please refer to Figures 1 to 7 : This invention proposes a fixing device for a wire harness frame, including a base 1, a linkage 3, a first transmission gear 4, a torsion member 5, a second transmission gear 6, a clamping member 7, and a connecting member 8; a fixing strap assembly 2 is installed on the top surface of the base 1; the fixing strap assembly 2 consists of a slider 21, a strap 22, and a connecting frame 23; the linkage 3 includes a toothed rod 31, a pushing block 32, and a fixing rod 33, wherein the toothed rod 31 passes through the base 1, and the fixing rod 33 is fixed and vertically connected to the top surface of the base 1; the first transmission gear 4 is movably connected to the top surface of the base 1 via a shaft; the torsion member 5 includes a lifting rod 51 and a rotating plate 52. The lifting rod 51 passes through the base 1 and is movably engaged inside the rotating plate 52; the second transmission gear 6 is movably connected to the top surface of the base 1 via a shaft; the clamping member 7 consists of a fixing ring 71, a rotating tube 72, a sliding plate 73, a clamping block 74, and a stop block 75. The fixing ring 71 is fixedly connected to the top surface of the base 1 via a rod, and the stop block 75 is fixedly installed on the top surface of the base 1 via a vertical rod; the connecting member 8 includes a fixing tube 81, a clamping ring 82, a torsion ring 83, and a threaded rod 84. The fixing tube 81 is fixedly connected to the side of the base 1, and the threaded rod 84 is connected to the inside of the fixing tube 81 via threaded engagement.

[0021] In addition, as attached Figure 1 Appendix Figure 4 and attached Figure 7 As shown, a pull rod 2101 is fixedly installed on the front end face of the slider 21. The top of the pull rod 2101 is provided with a toothed groove, which meshes with the first transmission gear 4. The outer end face of the strap 22 is a pull strap 2201. The bottom end of the pull strap 2201 is fixedly connected to the connecting frame 23. The connecting frame 23 passes through the base 1. Pulling the connecting frame 23 up and down moves the pull strap 2201 up and down, thereby adjusting the tightness of the strap 22. When the pull rod 2101 is pulled, the first transmission gear 4 is driven to rotate through the toothed groove, which in turn moves the slider 21 to change the position of the strap 22, thus adjusting the tightness and position of the strap 22. After adjustment, the pull rod 2101 is bent so that it cannot move back, thereby fixing the position of the pull rod 2101. The connecting frame 23 is bent so that it is fixedly engaged with the outside of the base 1, thereby fixing the position of the toothed rod 31 and fixing the wire harness.

[0022] In addition, as attached Figure 2 and attached Figure 3 As shown, the top surface of the support base 1 is provided with a sliding groove 101, and the bottom of the slide plate 73 is slidably engaged inside the sliding groove 101. The sliding groove 101 provides a directional sliding base for the slide plate 73. The support base 1 supports and connects other components to form a fixing device for the wire harness workshop. The fixing tube 81 on the side of the support base 1 cooperates with the threaded rod 84 to complete the connection between multiple sets of support bases 1, so that the device can be used individually or in multiple sets, and the length can be changed for more flexible use.

[0023] In addition, as attached Figure 5 As shown, two sets of rings are fixedly installed on the lifting rod 51. The two sets of rings abut against the upper and lower surfaces of the rotating plate 52 respectively. The rotating plate 52 has a circular hole inside, through which the wire harness passes. When the connecting frame 23 moves up and down, it drives the toothed rod 31 to move up and down through the insertion hole 3101. The toothed rod 31 drives the first transmission gear 4 to rotate through meshing transmission. The first transmission gear 4 drives the lifting rod 51 to move up and down, thereby adjusting the height of the rotating plate 52 to meet the constraints of the wire harness position.

[0024] In addition, as attached Figure 2 Appendix Figure 4 and attached Figure 7 As shown, the fixed retaining ring 71 internally engages with the rotating tube 72. The rotating tube 72 has teeth on its exterior, which mesh with the second transmission gear 6. The rotating tube 72 internally has a threaded rod that is fixedly connected to the inside of the slide plate 73. The clamping block 74 is fixedly connected to the slide plate 73 by a bolt assembly. The clamping block 74 and the abutment block 75 are at the same height. When the second transmission gear 6 is driven to rotate by the pull rod 2101, it drives the rotating tube 72 to rotate. The rotating tube 72 drives the threaded rod to move through the threaded engagement, which in turn drives the slide plate 73 to slide in the slide groove 101, changing the distance between the clamping block 74 and the abutment block 75. This adjusts the clamping force between the clamping block 74 and the abutment block 75, thus fixing the wire harness.

[0025] In addition, the outer sleeve of the fixed tube 81 is fitted with a snap ring 82. The snap ring 82 has a through groove at the top inside, through which a torsion ring 83 passes. The threaded rod 84 is connected to the inside of the fixed tube 81 by threaded engagement. When two sets of fixed tubes 81 are connected by the threaded rod 84, the two sets of support bases 1 are connected as one. Rotating the torsion ring 83 causes the snap ring 82 to rotate, and the shape of the fixed tube 81 changes. This allows the connection angle between two adjacent sets of support bases 1 to be adjusted. When multiple sets of support bases 1 are connected and used, the angle can be adjusted according to the curvature of the wire harness, improving the adaptability.

[0026] In addition, as attached Figure 5As shown, a insertion hole 3101 is provided inside the lower part of the toothed rod 31, and a connecting bracket 23 is inserted into the insertion hole 3101. A wedge plate is fixedly installed above the toothed rod 31. The inner side of the push block 32 is a wedge structure, and the inclined surface of the wedge structure fits against the inclined surface of the wedge plate on the toothed rod 31. The outer end of the push block 32 is connected to the upper part of the fixed rod 33 through a spring and a telescopic sleeve. A rectangular rod is fixedly installed on the inner side of the push block 32, and the end of the rectangular rod is engaged inside the rotating plate 52. When the toothed rod 31 moves down, it drives the push block 32 to move, causing the rectangular rod on the inner side of the push block 32 to push the rotating plate 52 to rotate, thereby changing the angle of the rotating plate 52. When the toothed rod 31 moves up, it drives the push block 32 to move, causing the rectangular rod on the inner side of the push block 32 to pull back the rotating plate 52, thereby tightening and binding the wire harness passing through the interior of the rotating plate 52.

[0027] The specific usage and function of this embodiment: In this invention, pulling the connecting frame 23 up and down causes the pull strap 2201 to move up and down, thereby adjusting the tightness of the strap 22. When the pull rod 2101 is pulled, the first transmission gear 4 is driven to rotate through the tooth groove for transmission, and at the same time, the slider 21 is moved to change the position of the strap 22, thereby adjusting the tightness and position of the strap 22. The tooth rod 31 causes the first transmission gear 4 to rotate through meshing transmission. The first transmission gear 4 drives the lifting rod 51 to move up and down, thereby adjusting the height of the rotating plate 52 to meet the constraints of the wire harness position. The second transmission gear 6 is driven to rotate by the pull rod 2101, which in turn drives the rotating tube 72 to rotate. The rotating tube 72 drives the threaded rod to move through the threaded engagement, which in turn drives the slide plate 73 to slide in the direction of the slide groove 101, causing the distance between the clamping block 74 and the abutment block 75 to change. Adjusting the clamping force between the clamping block 74 and the abutment block 75 achieves wire harness fixation. After adjustment, the pull rod 2101 is bent so that it cannot move back, thereby fixing the position of the pull rod 2101. The connecting bracket 23 is bent so that it is fixedly snapped onto the outside of the base 1, thereby fixing the position of the toothed rod 31 and achieving wire harness fixation.
