DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 2In order to improve the efficiency of using and dividing the wire harness tape, the dividing mechanism 2 in this embodiment includes a dividing box 21, a support frame 22, a connecting shaft 23, a sliding wheel 24, a connecting frame 25, a supporting spring 26, a pushing block 27 and a dividing knife 28. A pulling-out port is provided on the outer side of the tape box 1, and the dividing box 21 is fixed to the inner wall of the pulling-out port. When the user pulls out the tape, the tape is pulled out from the dividing box 21. After pulling out a suitable length, the tape is wound and adhered to the wire harness. The supporting frame 22 is fixed to the inner bottom wall of the dividing box 21, and the two ends of the connecting shaft 23 are respectively connected to the inner bottom wall of the supporting frame 22. The inner walls on the left and right sides are fixed, the sliding wheel 24 is rotatably connected to the outer side of the connecting shaft 23 through a bearing, the connecting frame 25 is fixed to the inner top wall of the dividing box 21, one end of the supporting spring 26 is fixed to the right inner wall of the connecting frame 25, and the other end of the supporting spring 26 is fixedly connected to the pushing block 27. After the winding of the automobile wiring harness is completed, the pushing block 27 is pushed forward by the sliding handle 29, and the front end of the pushing block 27 contacts the dividing knife 28, so that the dividing knife 28 cuts the tape, and the pushing block 27 is slidably connected to the inner walls on the front and rear sides of the connecting frame 25, and the dividing knife 28 is fixed to the lower surface of the pushing block 27.

[0024] In this embodiment, there are three sliding wheels 24, which are evenly distributed laterally on the outside of the connecting shaft 23. The longitudinal cross-section of the push block 27 is T-shaped. A discharge port is provided on the front of the dividing box 21, and a sliding port is provided on the front of the connecting frame 25. A handle 29 is slidably connected to the inner wall of the sliding port. The back of the handle 29 is fixedly connected to the front of the push block 27. The divided tape is pulled out from the discharge port to complete the dividing process. After the dividing is completed, the rebound force of the support spring 26 can push the push block 27 back to the starting point to facilitate the next tape dividing.

[0025] See also Figure 3 In order to improve the high temperature resistance of the tape, the tape assembly 3 in this embodiment includes a release film 31 placed on the inner wall of the dividing box 21. The release film 31 makes it easy for the tape to be pulled out of the dividing box 21, reduces the friction between the tape and the inner wall of the dividing box 21, and prevents the tape from being stuck or torn. An insulating layer 32 is bonded to the outer side of the release film 31, a high temperature resistant layer 33 is bonded to the outer side of the insulating layer 32, an anti-corrosion layer 34 is bonded to the outer side of the high temperature resistant layer 33, and a wear-resistant layer 35 is bonded to the outer side of the anti-corrosion layer 34.

The high temperature resistant layer 33 is a silicone layer, which increases the high temperature resistance of the tape so that it can be used for a long time in a high temperature environment without deformation or damage. The anti-corrosion layer 34 is a chloroprene rubber layer, which increases the corrosion resistance of the tape to avoid damage caused by erosion by chemical substances. The wear-resistant layer 35 is a polyester film layer, which improves the wear resistance of the tape, extends the service life of the tape, and reduces the replacement frequency.

[0027] The working principle of the above embodiment is:

[0028] (1) When the wire harness tape is used to improve the efficiency of cutting, when the user pulls out the tape, the tape is pulled out from the cutting box 21, and after being pulled out to a suitable length, the tape is wound and adhered to the wire harness. At the same time, after the winding of the automobile wire harness is completed, the push block 27 is pushed forward by the sliding handle 29, and the front end of the push block 27 contacts the cutting knife 28, so that the cutting knife 28 cuts the tape, and the cut tape is pulled out from the discharge port, completing the cutting process. After the cutting is completed, the rebound force of the support spring 26 can push the push block 27 back to the starting point to facilitate the next tape cutting and use.

[0029] (2) When the tape is used to improve its high temperature resistance, the release film 31 makes it easy to pull the tape out of the dividing box 21, reducing the friction between the tape and the inner wall of the dividing box 21, and preventing the tape from getting stuck or tearing. The insulating layer 32 improves the insulation performance of the tape to prevent short circuits or leakage in the electrical harness. The high temperature resistant layer 33 increases the high temperature resistance of the tape, allowing it to be used for a long time in a high temperature environment without deformation or damage. The anti-corrosion layer 34 increases the corrosion resistance of the tape to prevent damage caused by erosion by chemical substances. The wear-resistant layer 35 improves the wear resistance of the tape, extending the service life of the tape and reducing the frequency of replacement.
