Tensioner

Abstract

The invention provides a tensioner. The tensioner comprises a base, wherein square upright posts with hollow structures are vertically arranged at the two ends of the base; the top ends of the two square upright posts are connected with a U-shaped hollow pipe; the middle part of the lower end of the U-shaped hollow pipe is provided with a circular hole; a plurality of hanging rings are further arranged at the lower end of the U-shaped hollow pipe; a generator is arranged inside one of the square upright posts; a gear is arranged on a revolving shaft of the generator; a rack which rotates in cooperation with the gear is fixedly arranged on the inner side face of one of the square upright posts; the rack is arranged vertically; the generator is fixedly connected with a tension wire; the tension wire passes through the circular hole from the insides of the square upright posts and the U-shaped hollow pipe; the end part of the tension wire is connected with a pull ring; a storage battery is arranged inside the base; the storage battery is electrically connected with the generator through a power line; the output end of the storage battery is electrically connected with a USB (Universal Serial Bus) interface. The tensioner is simple in structure; the generator is pulled through the tension wire, so that body building and power generation of the generator are performed synchronously, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment, and in particular relates to a tensioner. Background technique [0002] There are many types of tensioners, generally spring tensioners, rubber strip tensioners and heavy hammer pulley tensioners. Spring tensioners are more commonly used, generally consisting of 5 wire springs and two wooden handles. Its pulling force is very large, and there is a pulling force of 6 kg per contract. The rubber strip tensioner can also be made into the style of a spring tensioner. A rubber strip of about 3 meters can be used to fix the handle at its two ends, which is more convenient to carry and has good practicability. The heavy hammer pulley tensioner is composed of a handle, a wire rope, a heavy hammer and a fixed pulley. Generally, they are fixed on the wall or used on a special metal frame. There are single-arm and double-arm styles. These stretchers can all realize the purpose of exercising th...
