Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0022] Please refer to Figures 1-5 The utility model embodiment provides a fixed-length tightening device for a wire harness, which comprises a spool barrel 2, a protective cover 1 is installed above the spool barrel 2, a winding shaft 11 is rotatably installed in the middle of the inside of the spool barrel 2, a pay-off angle 3 is rotatably installed on the outside of the spool barrel 2, an adjusting shaft 4 for rotation is arranged between the pay-off angle 3 and the spool barrel 2, a wire outlet hole 13 is arranged in the inside of the pay-off angle 3, a sleeve 16 is fixedly installed on the left side of the spool barrel 2, clamping grooves 17 are fixedly arranged on the surface of the sleeve 16, a positioning seat 14 is rotatably installed in the inside of the sleeve 16, and threading holes 15 are fixedly arranged on the surface of the positioning seat 14.

[0023] Specifically, the surface of the winding shaft 11 is wound with a wire bundle, the wire bundle is pulled out from the wire hole 13 inside the pull-out angle 3, the pull-out angle 3 is adjusted by the rotating structure between the adjusting shaft 4 and the reel drum 2, and then the angle of the pull-out angle 3 is adjusted, the pulled-out wire bundle is inserted into the wire hole 15 on the surface of the positioning seat 14, after the wire bundle is inserted, the positioning seat 14 is rotated by using the threaded connection structure between the positioning seat 14 and the sleeve 16, after the positioning seat 14 is rotated, the wire bundle is clamped and positioned in the middle between the clamping groove 17 and the wire hole 15 on the surface of the positioning seat 14, and then the wire bundle is timely stopped, after the wire bundle is positioned when the wire bundle has reached the required length, the wire bundle is convenient to cut off.

[0024] The upper end of the winding shaft 11 is fixedly connected with the gear shaft 9, the upper end of the gear shaft 9 is fixedly connected with the rotating rod 10, the upper end of the rotating rod 10 is connected with the winding spring piece 12, the outer side of the gear shaft 9 is engagedly installed with the gear disc 8, the center line of the gear disc 8 is penetratedly installed with the connecting shaft 7, one end of the connecting shaft 7 is fixedly connected with the rotating shaft 5, one end of the rotating shaft 5 is fixedly installed with the rocker 6, the gear disc 8 and the gear shaft 9 are in meshing structure, the upper and lower ends of the gear shaft 9 are respectively fixedly installed with the rotating rod 10 and the winding shaft 11, the rotating rod 10 and the protective cover 1 are in rotating connection, the upper end of the rotating rod 10 and one end of the winding spring piece 12 are in fixed connection, the gear disc 8 and the connecting shaft 7 are in fixed connection, and the gear disc 8 and the rotating shaft 5 are in fixed connection through the connecting shaft 7;

[0025] Specifically, the center lines of the three key components, the gear shaft 9, the winding shaft 11 and the rotating rod 10, coincide with each other, which ensures that they work together to achieve the expected mechanical effect. Specifically, the teeth on the surface of the gear shaft 9 perfectly mesh with the teeth on the surface of the gear disc 8, and this meshing structure is the core of the operation of the entire mechanical device. It transmits power through the action of a rocker 6. When the operator rotates the connecting shaft 7 by rotating the rocker 6 and the rotating shaft 5, the connecting shaft 7 transmits power to the gear disc 8, which rotates in turn, thereby driving the gear shaft 9 to rotate clockwise. During the clockwise rotation of the gear shaft 9, the winding shaft 11 below it also rotates clockwise. This clockwise rotation means that the wire bundle wound on the winding shaft 11 will be gradually lengthened to the desired length. At the same time, the rotating rod 10 rotates and pulls the upper end of the winding spring piece 12. The winding spring piece 12 is gradually tensioned during the pulling process, and finally exerts a pulling force on the rotating rod 10. When the elasticity of the winding spring piece 12 reaches its elastic critical point, it will drive the rotating rod 10 to rotate back, so that the rotating rod 10 rotates in the opposite direction. During the reverse rotation of the rotating rod 10, the wire bundle is wound in the opposite direction, thereby tightening the wire bundle. The elastic critical point of the winding spring piece 12 corresponds to a certain length of the wire bundle after it is lengthened, ensuring that the wire bundle will not be excessively lengthened when it is tightened. Through this design, the winding spring piece 12 can effectively control the length of the wire bundle during reverse rotation, achieving constant length tightening of the wire bundle. This design not only avoids excessive lengthening of the wire bundle, but also ensures the stability and reliability of the entire mechanical device.

[0026] The working principle of the utility model is:

[0027] In use of the utility model, the operator first winds the wire harness on the winding shaft 11, then shakes the rocker 6, the rocker 6 drives the connecting shaft 7 to rotate through the rotating shaft 5, the connecting shaft 7 drives the gear disc 8 to rotate again, the gear disc 8 is meshed with the gear shaft 9 through the gear, so that the gear shaft 9 also rotates, the rotation of the gear shaft 9 drives the winding shaft 11 below it to rotate synchronously, thereby gradually releasing the wire harness wound on the winding shaft 11, in the process of releasing the wire, the rotating rod 10 rotates along with the rotation of the gear shaft 9 and pulls the winding spring piece 12 at the upper end, the winding spring piece 12 is gradually stretched and stores elastic potential energy, when the wire harness is released to the required length, the operator stops shaking the rocker 6, at this time the elastic potential energy of the winding spring piece 12 reaches the critical point, it drives the rotating rod 10 to rotate reversely, the reverse rotation of the rotating rod 10 drives the reverse rotation of the gear shaft 9 and the winding shaft 11, thereby winding the wire harness reversely, realizing the fixed-length tightening of the wire harness, simultaneously, the operator can change the wire releasing direction of the wire harness by adjusting the angle of the wire releasing angle 3, and clamps the wire harness between the clamping groove 17 and the wire hole 15 by rotating the positioning seat 14, facilitating the cutting and use of the wire harness, the whole device is simple in structure and convenient to operate, and can effectively realize the fixed-length tightening of the wire harness.
