Description

A kind of rotating disc type tension fitness machine

technical field

The utility model relates to the field of rehabilitation fitness equipment, in particular to a turntable type tension fitness equipment.

Background technique

Stretcher is a kind of equipment suitable for mass fitness exercises, and it is also used for exercise and rehabilitation training for patients with certain mobility impairments. It has a wide range of applicable people and use bases. There are many kinds of tension fitness machines on the market, such as spring tension fitness machines, which are composed of several springs and handles fixed at both ends of the springs, which can be used for chest expansion exercises, or stretched around the back of the body for back stretching. Lying-lying tension fitness equipment, the fitness person lies on the fitness bed on his back, and pulls down the handle from above with both hands. The handle is connected to the gravity weight on the side of the fitness equipment through steel cables and pulleys, and the weight of the weight can be changed to change the tension. Size: elastic cord tensioner, the handle is connected to the elastic cord, and the other end of the elastic cord is connected to the wall or a fixed bracket, so that the bodybuilder can perform stretching exercises in various postures. The main action when using tension is to bend the forearm or the upper arm. When bending the arm, it also uses muscles in other parts of the body, such as the pectoral muscles and back muscles, which can exercise most of the upper body muscles.

But existing tension gauge also has its weak point, and spring tension body building device is simple in structure, and is easy to carry, but function is also less, only applicable to the action of one or two kinds of stretching; Stretching actions in specific postures such as sitting or sitting, and the equipment is huge, which is only suitable for wide spaces such as gyms; the elastic rope fitness machine has a simple structure, but the tension cannot be adjusted, and the length of the rope is long, so it is not easy to carry.

By inquiring prior art documents and patents, the following retrieval results about the tension fitness device with the turntable structure are obtained:

1. A tension fitness device; application number: CN99242219.1; applicant: Wu Zairong; abstract: a tension fitness device, mainly composed of steel wire, spring steel sheet, directional shaft, resistance ring and a central shaft fixed on the shell And a pair of friction pads. The steel wire is wound on the directional shaft, one end is fixed on the directional shaft, and the other end extends out of the shell; the directional shaft is placed on the central shaft; the two ends of the spring steel sheet are respectively fixed on the central shaft and the directional shaft; the resistance ring fixed sleeve Placed on the directional shaft; a pair of friction pads are clamped on both sides of the resistance ring. The tension fitness device is small in size, and the size of the force can be adjusted arbitrarily according to the different needs of different bodybuilders, and the escape function can be added.

2. Adjustable tension fitness device; application number: CN201420404677.7; applicant: Deng Yuefei; abstract: adjustable tension fitness device, including a shell, a tension device and a tension adjustment device. The tension device includes two handles and a drawstring. One end of the rope is fixed on one side of the handle, and the other end of the pull rope is wound around the lower end of the pulley. The tension adjusting device includes two symmetrically arranged pulleys. The lower ends of the two pulleys are connected by an elastic belt. The middle position of the body is fixed with a rotating shaft, the two sides of the rotating shaft are respectively provided with threads, the directions of the threads are opposite, and a shaft sleeve is respectively screwed on the threads on both sides, and the shaft sleeves are respectively fixed with elastic belts, and the shaft sleeves are arranged in a slide rail for Sliding, one end of the rotating shaft is provided with a knob, using the above device, the bodybuilder can adjust the tension of the elastic belt by turning the knob, and then adjust the tension, which is convenient to use.

It can be seen from the above that the existing stretching fitness equipment has the disadvantages of complex structure, inconvenient maintenance, and undiversified ways of realizing the stretching action of the bodybuilder.

Contents of the invention

The utility model provides a turntable type tension fitness device, which has a compact structure, is convenient to carry, and is convenient to maintain, and can realize stretching actions in various postures of the user. Besides daily fitness use, it can also be applied in the field of rehabilitation exercise for patients' limbs.

The technical scheme of the utility model is achieved in that:

A kind of turntable type tension fitness machine, two symmetrical turntables are arranged in parallel inside the housing, the turntables can rotate around the rotating shaft, resistance parts are set on the turntables to make the turntables have a restoring force, and the restoring force is the pulling force that the bodybuilder needs to apply. One end is respectively fixed on the peripheral edge of the turntable, that is, the drag cable only revolves along the peripheral edge of the turntable, and the other end of the drag cable extends out of the tension fitness device from the cable hole below the casing, and is connected with a handle at the end.

The rotating shaft is located at the center of the turntable. The resistance component is a torsion spring. The torsion spring is coaxial with the turntable axis. One end of the torsion spring is fixed on the turntable, and the other end is fixed on the housing. That is, the torsion spring provides the restoring force to the turntable. One's own situation selects the tension fitness equipment with torsion spring of different specifications to use.

The peripheral edge of the turntable is groove-shaped or V-shaped, which can effectively prevent the drag cable from slipping out from the peripheral edge of the turntable.

A rotatable hook is arranged above the casing, and the hook can be hung in a firm position, and the bodybuilder pulls the handle under the tension fitness device. Or the hook is hooked in the horizontal position, and the body builder pulls the handle at the side of the tension body building apparatus. The hook can also be a closed hook to prevent the hook from coming off.

At the limit position, the corresponding fixing ball on the cable is located outside the casing. The diameter of the ball is larger than that of the cable hole. The ball can fix the limit position of the cable and prevent the cable from being thrown when the cable is not stressed. The dynamic friction cable hole is damaged.

The edge of the cable hole is smooth and has a rounded shape to prevent friction and wear of the cable edge. In addition, the cable can also be stretched at multiple angles or even perpendicular to the direction of the tension fitness machine, which can meet the needs of bodybuilders in different exercise directions.

The utility model has the advantages of:

1. The utility model's turntable tension fitness device is small in size, light in weight, easy to carry and easy to maintain.

2. The rotary disc type tension fitness device of this utility model can realize stretching at various angles and positions of the bodybuilder, and has powerful functions and wide uses.
