Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, specifically an auxiliary device for installing automotive wiring harness sheaths. Background Technology

[0002] An automotive wiring harness sheath installation aid is a device used to assist in the installation process of automotive wiring harness sheaths. It typically consists of a base, sliding frame, adjusting components, and support structure, and can be adapted and operated for wiring harness sheaths of different sizes and shapes.

[0003] The working principle is as follows: First, the wire harness sheath port is placed on a specific support structure. By adjusting the components, such as rotating the screw or starting the motor to drive the relevant components, the support structure is moved to widen the sheath port. Then, the displacement components, such as the motor driving the lead screw to rotate, are used to adjust the distance between the two sets of sliding frames, thereby straightening the wire harness sheath and keeping both ports open so that workers can easily pass the wire harness through the sheath.

[0004] Traditional devices often use a single-end cylinder to push or a double-claw to pull the opening. This can easily lead to localized contraction or excessive stretching of the sheath opening due to unbalanced forces. As a result, one side may be fully expanded while the other side remains close to the wire harness. When the wire harness is inserted, it may get stuck in the contracted area or even scratch the inner wall of the sheath. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes an auxiliary device for installing automotive wiring harness sheaths.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an auxiliary device for installing automotive wiring harness sheaths, including two fixed compartments, each fixed compartment being provided with a support mechanism, the support mechanism including several arc-shaped rods in two annular arrays, a rubber layer being fixedly connected to the upper part of the arc-shaped rods on the front and rear sides that are close to each other, a support rod being fixedly connected to the side of the arc-shaped rods on the front and rear sides that are far apart, a first sliding block being fixedly connected to the side of the support rods on the front and rear sides that are far apart, a threaded disc being threadedly connected to the side of the several first sliding blocks in the annular array that is far apart from the support rod, a T-shaped circular handle being fixedly connected to the outer wall of the threaded disc, and a first circular hole being opened in the middle of the T-shaped circular handle.

[0007] Preferably, the fixed chamber includes two circular fixing blocks, each with a second circular hole in the center. The two circular fixing blocks have several T-shaped sliding grooves arranged in a ring on their opposite sides, and the inner walls of the several T-shaped sliding grooves arranged in a ring on the front and rear sides have T-shaped annular grooves on their opposite sides.

[0008] Preferably, the inner wall of the T-shaped sliding groove is slidably connected to the support rod and the outer wall of the first sliding block, and the inner wall of the T-shaped annular groove is rotatably connected to the threaded disc and the outer wall of the T-shaped annular handle.

[0009] Preferably, a first sliding seat is fixedly connected to the lower part of the circular fixing block. The first sliding seat includes two connecting blocks. A second sliding block is fixedly connected to the lower part of the connecting block. A threaded hole is opened in the middle of the second sliding block. The upper part of the connecting block is fixedly connected to the lower part of the circular fixing block.

[0019] The support mechanism 1 can enlarge the sheath opening to facilitate the insertion of the wire harness. In use, by rotating the T-shaped ring handle 16, the threaded disc 15 and several sliding blocks 14 rotate. The sliding blocks 14 drive several support rods 13 and several T-shaped sliding grooves 23 to slide, thereby causing several arc rods 11 and rubber layer 12 to move outward to enlarge the sheath opening.

[0021] The output of motor 41 drives the bidirectional threaded rod 42 to rotate. The bidirectional threaded rod 42 rotates with the two threaded holes 33, causing the two second sliding blocks 32 to slide with the sliding groove 52, thus straightening the sheath.

[0022] Working principle: The support mechanism 1 can enlarge the sheath opening to facilitate the insertion of the wire harness. In use, by rotating the T-shaped ring handle 16, the threaded disc 15 and several sliding blocks 14 rotate. The sliding blocks 14 drive several support rods 13 and several T-shaped sliding grooves 23 to slide, thereby causing several arc rods 11 and rubber layer 12 to move outward to enlarge the sheath opening. This structure drives multiple support rods 13 synchronously through the threaded disc 15. The radial expansion of all support rods 13 is consistent, ensuring that the sheath opening is a perfect circle and opens evenly, completely avoiding wire jamming caused by uneven opening.

[0023] The output of motor 41 drives the bidirectional threaded rod 42 to rotate. The bidirectional threaded rod 42 rotates with the two threaded holes 33, causing the two second sliding blocks 32 to slide with the sliding groove 52, thus straightening the sheath.
