The threading device is an excellent auxiliary tool for pulling a guide rope in a pipe. A smooth and elastic surface can enable the threading device to easily pass through a narrow passage. In a technical solution of a threading machine with the patent number 2022203086254 and the practical name of a threading machine, the pre-tightening between the synchronous belt assembly and the guide rope disc is controlled by a tensioning assembly. Since the tensioning assembly is located in the threading machine body, it is inconvenient to adjust. SUMMARY

[0003] The purpose of the embodiment of the application is to provide a threading machine tensioning structure which can achieve the function of simple pre-tightening adjustment.

[0004] The embodiment of the application provides a threading machine tensioning structure, which comprises:

[0005] The threading machine shell is provided with a handle, and the threading machine shell is provided with a disc inside.

[0006] The threading machine shell is further provided with a tensioning mechanism, and the tensioning mechanism is located on the outside of the disc. The tensioning mechanism enables the rope on the disc to be pre-tightened on the disc.

[0007] Further, the tensioning structure comprises an adjusting screw, a fixed nut, a pressing plate, a deformation body, a fixed sheet, a limiting frame, a locking nut, a support plate, a transmission belt, a rotating wheel and a driving wheel. The fixed sheet is fixed to the support plate. The rotating wheel and the driving wheel are fixed to the support plate, and the driving wheel drives the rotating wheel to rotate through the transmission belt. The fixed nut is fixed to the threading machine shell. The relative position between the adjusting screw and the fixed nut is adjusted to control the distance between the pressing plate and the fixed sheet, and then the deformation degree of the deformation body is adjusted. The external adjusting screw is convenient to adjust.

[0008] Further, the support plate can rotate around the center of the driving wheel. The axis of the adjusting screw is parallel to the tangent line tangent to the disc. The rotating wheels are uniformly distributed on the support plate. The pressing plate is fixed to the threading machine shell, and the pressing plate is deformable. The tensioning structure is ingenious. The adjusting screw passes through the fixed nut in sequence to ensure the stability of the locking bolt. The fixed nut is on the pressing plate. The relative position between the adjusting screw and the pressing plate is adjusted to change the elasticity of the deformation body, and then the distance between the transmission belt and the guide rope is adjusted to ensure that the guide rope is collected and sent in the appropriate and reasonable range, reduce the labor intensity of the operator, enhance the use experience, and be conducive to the promotion and application of the above-mentioned threading machine in the market.
