Description

Technical Field

[0001] The utility model relates to the technical field of wire harness sheaths, in particular to a rotating sheath for an automobile wire harness. Background Art

[0002] Wire harness covers are tubular structures used to protect wire harnesses. They provide physical protection, such as preventing abrasion and damage to the wire harness.

[0003] After searching, a Chinese patent with publication number CN216598805U discloses a wiring harness rotation guide sheath, whose technical solution includes a first adapter tube; a second adapter tube; a sheath body, one end of the sheath body is rotatably connected to the first adapter tube, and the other end of the sheath body is rotatably connected to the second adapter tube, a through hole is opened on the sheath body, and a branch pipe is integrally provided with the sheath body along the outer peripheral surface of the through hole; the patent has the advantages of being rotatable and guideable, while avoiding interference between the wiring harness and surrounding parts.

[0004] Based on the above search and combined with the existing technology, we found that:

[0005] In order to meet the flexible needs during operation, the existing technology will set the sheath to be rotatable, such as the above-mentioned patent. However, the number of branching structures on the surface of the sheath is often fixed, and it cannot be flexibly increased or decreased according to the construction requirements of the wire harness. In actual wire harness construction, different projects or equipment may require different numbers of branching structures to meet the needs of organizing and managing the wire harness. Since the number of branching structures cannot be flexibly increased or decreased, this limits the applicability of this sheath in different construction scenarios, resulting in a narrow actual scope of application, and therefore has limitations. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a rotating sheath for automobile wiring harness, which can increase or decrease the number of branch pipes according to design requirements. At the same time, the sheath body can be rotated at will to meet operational requirements.

[0007] The technical solution to achieve the purpose of the utility model is: an automobile wiring harness rotating sheath, comprising a sheath body, both sides of which are provided with corrugated protective tubes, and also comprising a connecting mechanism and a branching mechanism;

[0008] The connecting mechanism is provided between the sheath body and the corrugated protective tube;

[0009] The branching mechanism includes a plurality of equidistantly arranged grooves on the outer peripheral wall of the sheath body, and a circular opening is provided at the middle end of the groove, and a branching pipe is slidably installed in each circular opening, and a tensioning spring is fixedly installed between each branching pipe and the inner peripheral wall of the sheath body. A sealing unit is also provided in the groove, and the sealing unit is used to seal the circular opening.

[0010] Preferably, the connecting mechanism includes a pair of adapter ring plates fixedly mounted on one end of the two corrugated protective tubes, and limiting ring grooves are provided on opposite ends of the two adapter ring plates.

[0011] Preferably, both sides of the sheath body are rotatably connected to the limiting ring grooves on the adapter ring plate.

[0012] Preferably, a pair of limit blocks are fixedly installed on the inner peripheral wall of the sheath body at positions close to the branch pipes, and the distance between the limit blocks and the adjacent circular openings is the same as the length of the branch pipes.

[0013] Preferably, the sealing unit comprises a plurality of pairs of cover plates, the plurality of pairs of cover plates are slidably connected to the inner wall of the sink, and a protrusion integrally formed with the outer wall of one side of each cover plate is provided.

[0014] Preferably, a corrugated membrane is fixedly connected between the opposite sides of each pair of cover plates and the sink.

[0015] Preferably, each of the cover plates is provided with a number of recesses on both sides, and a hemispherical head block is slidably installed in the recess, a reset spring is fixedly connected between the hemispherical head block and the recess, and a number of hemispherical slots are provided on the inner walls on both sides of the sink, and the hemispherical slots are adapted to the hemispherical head block.

[0016] Compared with the prior art, the present invention has the following significant advantages:

[0017] Firstly, the utility model adopts the above structure, when the sealing unit is pulled away from the circular opening, the branch pipes provided can be extended from the circular opening under the action of the tension spring, so that the number of branch pipes can be increased or decreased according to actual operation requirements, greatly improving its flexibility;

[0018] Secondly, under the action of the reset spring, when the hemispherical slot and the hemispherical head block are aligned, they can be engaged and thus fix the cover plate. The cover plate will only move when pushed by an external force. Therefore, when branching is not needed, the corresponding two cover plates can be pushed to the top of the circular opening to retract the branch pipe. Conversely, when the two cover plates are pushed away from each other, the branch pipe can be automatically ejected under the action of the tension spring, thereby adding a branching structure and improving the flexibility of the rotating sheath.

[0019] The invention solves the problem in the prior art that the number of wiring harness arc sleeve branching structures is fixed and the number of branching structures cannot be flexibly increased or decreased according to design requirements. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides an automobile wiring harness rotating sheath through improvement. The technical solution of the utility model is:

[0030] like Figure 1-5 As shown, a rotating sheath for automobile wiring harness includes a sheath body 3, with corrugated protective tubes 1 provided on both sides of the sheath body 3, and also includes a connecting mechanism and a branching mechanism;

[0031] The connecting mechanism is provided between the sheath body 3 and the corrugated protective tube 1 ; the connecting mechanism is used to achieve rotational connection between the sheath body 3 and the corrugated protective tube 1 .

[0032] The branching mechanism includes a plurality of equidistant grooves 11 on the outer peripheral wall of the sheath body 3, and a circular opening is provided at the middle end of the grooves 11, and a branching branch pipe 8 is slidably installed in each circular opening, and a tensioning spring 9 is fixedly installed between each branching branch pipe 8 and the inner peripheral wall of the sheath body 3. A sealing unit is also provided in the groove 11, and the sealing unit is used to seal the circular opening; through the above structure, when the sealing unit is pulled away from the circular opening, under the action of the tensioning spring 9, the branching branch pipe 8 can be extended from the circular opening, so that the number of branching branch pipes 8 can be increased or decreased according to actual operation requirements, which greatly improves its flexibility.

[0033] Further, such as Figure 2-Figure 3 As shown, the connection mechanism includes a pair of adapter ring plates 2 fixedly mounted on one end of the two corrugated protective tubes 1, and a limiting ring groove 10 is provided on the opposite end of the two adapter ring plates 2.

[0034] Furthermore, both sides of the sheath body 3 are rotatably connected to the limiting ring grooves 10 on the adapter ring plate 2; through this arrangement, the sheath body 3 can be rotated compared to the corrugated protective tube 1, thereby improving its flexibility of use.

[0035] As a further solution of the present invention, Figure 2-Figure 3 As shown, a pair of limit blocks 7 are fixedly installed on the inner wall of the sheath body 3 near the branch pipe 8, and the distance between the limit blocks 7 and the adjacent circular opening is the same as the length of the branch pipe 8; through the above structure, when the circular opening is blocked, the branch pipe 8 can be retracted into the circular opening, and the limit blocks 7 set can be used to fix the branch pipe 8 well.

[0036] As a further solution of the present invention, the sealing unit includes multiple pairs of cover plates 4, which are slidingly connected to the inner wall of the sink 11, and each cover plate 4 is provided with a protrusion 5 with an integral structure on one side of the outer wall; through the above structure, the provided protrusion 5 is utilized to facilitate external force to push the cover plate 4 to move.

[0037] Further, such as Figure 1 and Figure 3 As shown, a corrugated membrane 6 is fixedly connected between the opposite sides of each pair of cover plates 4 and the sink 11 ; the provided corrugated membrane 6 can improve the protection effect of the sink 11 .

[0038] Further, such as Figure 5 As shown, a plurality of recesses 12 are provided on both sides of each cover plate 4, and a hemispherical head block 14 is slidably installed in the recess 12, and a return spring 13 is fixedly connected between the hemispherical head block 14 and the recess 12, and a plurality of hemispherical slots 15 are provided on the inner walls on both sides of the sink 11, and the hemispherical slots 15 are adapted to the hemispherical head block 14.

[0039] Through the above structure, under the action of the reset spring 13, when the hemispherical slot 15 is aligned with the hemispherical head block 14, they can be snap-fitted to achieve the fixation of the cover plate 4. Only when the cover plate 4 is pushed under the action of external force, the cover plate 4 will move; therefore, when there is no need to branch the line, the corresponding two cover plates 4 can be pushed to the top of the circular opening to achieve the retraction of the branch line branch 8; on the contrary, when the two cover plates 4 are pushed away from each other, under the action of the tensioning spring 9, the branch line branch 8 can automatically pop out, thereby realizing the addition of a branch line structure and improving the flexibility of the rotating sheath.

[0040] The specific working method is: when in use, the sheath body 3 is rotated compared with the corrugated protective tube 1 through the provided adapter ring plate 2 and the limiting ring groove 10, thereby improving its flexibility in use; when there is no need to branch the line, the corresponding two cover plates 4 can be pushed to the top of the circular opening to realize the retraction of the branch line pipe 8, and at the same time, cooperate with the provided limiting block 7 to fix the branch line pipe 8 well; on the contrary, when the two cover plates 4 are pushed away from each other, the branch line pipe 8 will no longer be blocked, and under the action of the tensioning spring 9, the branch line pipe 8 automatically pops out. At this time, the popped-out branch line pipe 8 can be used for branching, and the flexible increase or decrease of the branch line structure can be used to achieve the purpose of improving the flexibility of the rotating sheath.
