Technical Field

[0001] This utility model belongs to the field of wire harness sheathing technology, and in particular relates to a wire harness fixing sheath. Background Technology

[0002] Wire harness fixing sleeves are key components used to protect and regulate the layout and operation of wire harnesses. They are widely used in automobiles, industrial equipment, home appliances, rail transportation and other fields. Their function is to ensure that wire harnesses work stably in complex environments by physically wrapping, fixing and protecting them, while improving the cleanliness and safety of the internal space of the equipment.

[0003] Currently, existing methods for securing wire harnesses mostly use cable ties, clips, etc., but the disassembly process is cumbersome, often requires the use of professional tools, and is prone to damaging the wire harness during disassembly. Moreover, these methods have poor compatibility with different specifications of wire harnesses.

[0004] To address the aforementioned issues, this application proposes a wire harness fixing sleeve. Utility Model Content

[0005] The purpose of this utility model is to provide a wire harness fixing sleeve, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a wire harness fixing sleeve, including a protective sleeve and a fixing base. It has a through groove, and two symmetrical inserts are arranged in the through groove. Two symmetrical elastic clips are arranged on one side of the protective sleeve, and a fixing block is fixed on the side of the elastic clips that are far apart from each other. The fixing block has a slot to insert the insert, a smooth block, and a movable block that is threadedly connected to a screw at its top. The insert is fixed to the smooth block through a connecting plate. The rotation of the screw drives the insert to move laterally through the movable block, the smooth block, and the connecting plate.

[0008] Furthermore, the fixed block has an inclined guide surface on the side away from the protective sleeve, and the smooth block has an inclined guide surface on one side.

[0009] Furthermore, the fixed base has cavities located on both sides of the through groove. The screw is rotatably installed in the cavity. A guide rod parallel to the screw is fixed in the cavity, and the guide rod is slidably connected to the guide block fixed at the bottom of the smooth block.

[0010] Furthermore, the fixing base has cavities two located on both sides of the through groove, and the fixing base also has a cavity three located above the cavity two. A bevel gear two is respectively installed in the cavity two and the cavity three, and the bevel gear two is fixedly connected to each other by a vertical rotating shaft two. A bevel gear one that meshes with the bevel gear two is installed in the cavity two, and the bevel gear one is fixed coaxially with the screw through the rotating shaft one. A bevel gear three is installed in the cavity three, and the bevel gear three is fixedly connected to each other by a horizontal rotating shaft three.

[0011] Furthermore, the fixed base has a cavity four located above the fixed base, and two meshing bevel gears four are provided in the cavity four. One bevel gear four is fixedly connected to the outer wall of bevel gear three, and the other bevel gear four is fixedly connected to the knob above the fixed base through a rotating shaft four.

[0012] Furthermore, multiple through slots are arranged laterally.

[0013] Furthermore, the protective sleeve is fixed to the elastic clip via a connecting ring, and the outer diameter of the elastic clip is equal to the inner diameter of the through groove.

[0014] Furthermore, a positioning block is fixedly provided on the outer wall of the connecting ring, and the fixing seat is provided with a positioning groove that cooperates with the positioning block.

[0015] This utility model has the following beneficial effects:

[0016] This utility model achieves rapid clamping and fixing of the wire harness by pushing the fixing block and elastic clip closer to the wire harness through the insertion block when the fixing base and protective sleeve are connected, thereby clamping and fixing the wire harness.

[0017] This invention uses a screw rotation to drive a moving block to move laterally, and a smooth block to push the connecting plate and the insertion block to move, thereby controlling the deformation of the elastic clip when the fixing seat and the protective sleeve are inserted, and thus fixing wire harnesses with different outer diameters.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0028] Please see Figure 1 - Figure 4As shown, this utility model is a wire harness fixing sleeve, including a protective sleeve 2 and a fixing base 1. A through groove 101 is provided, and two symmetrical insert blocks 4 are provided in the through groove 101. Two symmetrical elastic clips 14 are provided on one side of the protective sleeve 2, and a fixing block 15 is fixed on the side of the elastic clips 14 that are far apart from each other. The fixing block 15 has a slot 1501 to be inserted into the insert block 4. A smooth block 3 is provided, and a moving block 301 that is threadedly connected to a screw 5 is fixed at the top. The insert block 4 is fixed to the smooth block 3 through a connecting plate 401. The rotation of the screw 5 drives the insert block 4 to move laterally through the moving block 301, the smooth block 3 and the connecting plate 401.

[0029] This embodiment provides a wire harness fixing sleeve, through which the wire harness passes through the protective sleeve 2 and between two elastic clips 14. The elastic clips 14 are then inserted into the through slot 101. During insertion, the insert block 4 applies force to the fixing block 15, causing the elastic clips 14 to deform and clamp the wire harness. The outer sheath of the wire harness has a certain deformation capacity, and the wire harness can still be clamped after the insert block 4 is inserted into the slot 1501. The screw 5 rotates to drive the moving block 301 to move, and the smooth block 3 and the connecting plate 401 drive the insert block 4 to move laterally, adjusting the distance between the two insert blocks 4, thereby controlling the deformation of the elastic clips 14, realizing the adjustment of the clamping force of the wire harness or applicable to the fixing of wire harnesses with different outer diameters. The material of the elastic clips 14 can be engineering plastic or spring steel.

[0030] The fixing block 15 has an inclined guide surface on the side away from the protective sleeve 2, and the smooth block 3 has an inclined guide surface on one side. After the fixing block 15 contacts the insert block 4, the two inclined guide surfaces cooperate with each other to guide the fixing block 15 to deform the elastic clip 14.

[0031] The fixed base 1 has cavities 102 located on both sides of the through groove 101. The screw 5 is rotatably installed in the cavity 102. A guide rod 6 parallel to the screw 5 is fixed in the cavity 102. The guide rod 6 is slidably connected to the guide block 302 fixed at the bottom of the smooth block 3. The guide rod 6 and the guide block 302 cooperate to guide the movement of the smooth block 3, thereby ensuring that the insert block 4 moves smoothly laterally.

[0032] The fixed base 1 has cavities 103 on both sides of the through groove 101 and cavities 104 above the cavities 103. Two bevel gears 8 are respectively installed in cavities 103 and 104, and are fixedly connected by a vertical shaft 801. A bevel gear 7 meshes with the bevel gear 8 in cavity 103, and is coaxially fixed to the screw 5 via a shaft 701. A bevel gear 9 is installed in cavity 104, and is fixedly connected by a horizontal shaft 901. Rotation of shaft 901 drives the two bevel gears 9 to rotate, which in turn drives the bevel gear 7 in cavity 102 to rotate, thereby causing the two screws 5 to rotate synchronously, achieving synchronous adjustment of the insert block 4 and ensuring synchronous reverse movement of the insert block 4.

[0033] The fixed base 1 has a cavity 105 located above the fixed base 1, and two meshing bevel gears 10 are provided in the cavity 105. One bevel gear 10 is fixedly connected to the outer wall of the bevel gear 901, and the other bevel gear 10 is fixedly connected to the knob 11 above the fixed base 1 through the rotating shaft 1101. By rotating the knob 11, the bevel gear 10 can be rotated, thereby driving the rotating shaft 901 to rotate.

[0034] The through slots 101 are arranged horizontally in multiple ways. Each through slot 101 can independently install a protective sleeve 2, thereby fixing multiple wire harnesses on the same fixing base 1 at the same time. During subsequent maintenance or operation, a single wire harness can be removed independently without affecting the fixing of other wire harnesses.

[0035] The protective sleeve 2 is fixedly connected to the elastic clip 14 via the connecting ring 12, and the outer diameter of the elastic clip 14 is equal to the inner diameter of the through groove 101. The outer wall of the connecting ring 12 is fixed with a positioning block 1201, and the fixing seat 1 is provided with a positioning groove 106 that cooperates with the positioning block 1201. The cooperation between the positioning block 1201 and the positioning groove 106 can restrict the movement direction of the protective sleeve 2 and prevent the insertion block 4 from being misaligned with the slot 1501.

[0036] It is understandable that this utility model can quickly clamp and fix wire harnesses, and it can also be applied to clamping and fixing wire harnesses of different sizes.

[0037] A specific application of the operation process of this embodiment is as follows: the wire harness passes through the protective sleeve 2 and the connecting ring 12 and passes between the two elastic clips 14. When the elastic clips 14 are sent into the through groove 101, the positioning block 1201 is inserted into the positioning groove 106. When inserted, the insert 4 pushes the fixing block 15 closer to the wire harness, thereby driving the elastic clips 14 closer to the wire harness to clamp and fix the wire harness. Then the insert 4 is inserted into the slot 1501 to complete the connection between the fixing seat 1 and the protective sleeve 2. By rotating the knob 11, the two inserts 4 can move synchronously in opposite directions to adjust the distance between the inserts 4, thereby controlling the deformation of the elastic clips 14, realizing the control of the clamping force of the wire harness or for fixing wire harnesses with different outer diameters.
