technical field

The invention relates to a physical exercise training device, in particular to an upper limb training device.

Background technique

Physical exercise is one of the effective ways for modern people to enhance their physique, prevent diseases, adjust their psychology, entertain their bodies and minds, and adapt to society. It uses a variety of equipment to exercise upper limbs, and exercises various parts of the human body to improve people's performance in a certain sport. athletic ability. For the exercise of upper limb strength, people have invented some upper limb exercise equipment that can adjust the damping of parts when they move, but the resistance adjustment range of this type of upper limb exercise equipment is relatively narrow, which cannot satisfy the user's upper limb exercise, and this type of upper limb exercise equipment The structure is complex, there are many accessories, the noise is loud during use, the moving parts are easy to wear, accidents are prone to cause user injuries, the requirements for the site are high, and the cost is high.

Contents of the invention

The object of the present invention is to provide an upper limb training device capable of exercising the user's upper limbs, which has a simple structure and can adjust the exercise intensity of the user.

In order to achieve the above object, the present invention adopts the following technical solutions: an upper limb training device, comprising a base and a bracket fixed on the base, the bracket is provided with several exercise rope rollers arranged up and down, and the exercise rope rollers at least include damping Roller and several driven rollers, exercise rope is surrounded on the exercise rope roller, and the damping roller is matched with damping device, and the damping device is used to adjust the damping size when the damping roller rotates.

When using the equipment of the present invention, the user pulls the exercise rope by hand and drives the damping roller and the driven roller to rotate, and the user pulls the exercise rope by climbing to make the upper limb exert force and move so as to achieve the purpose of exercising the upper limb. The invention has fewer parts, lower production cost, lower requirements on the site, lower noise during use, and can avoid safety accidents caused by damaged parts.

Preferably, the damping device includes several cylinders, the cylinders are formed with a first chamber and a second chamber, the first chamber communicates with the second chamber, and the second chamber is relatively located in the second chamber. On the upper side of a chamber, and a regulating valve is provided between the first chamber and the second chamber, the cylinder has an outlet shaft, the inner end of the outlet shaft is located in the first chamber, and the outlet shaft The outer end of the cylinder extends to the outside of the cylinder and is linked with the damping roller. The end of the cylinder away from the outer end of the shaft is hinged to the bracket. The damping roller rotates to make the shaft retract or extend. The first chamber is filled with liquid, and the regulating valve is used to adjust the size of the passing section when the liquid flows from the first chamber to the second chamber.

When using the equipment of the present invention, the user pulls the exercise rope by hand and drives the damping roller and the driven roller to rotate. Since the output shaft of the cylinder body is linked with the damping roller, the output shaft of the cylinder body will perform a reciprocating motion of retracting and extending. When the output shaft retracts, the output shaft pushes the liquid to be resisted, and the damping roller continues to rotate so that the output shaft continues to push the liquid into the second chamber; then the output shaft extends outward, because the second chamber is located above the first chamber and is located The liquid in the second chamber flows back to the first chamber under the influence of gravity.

Touch the regulating valve as needed to adjust the size of the section through which the liquid flows from the first chamber to the second chamber. When the size of the section through which the liquid can pass becomes larger, the inner end of the outlet shaft is easier to enter the first chamber. When the liquid is pushed, the damping of the damping roller is small, and the user can easily pull the exercise rope; when the cross-sectional size that the liquid can pass through becomes smaller, the inner end of the output shaft pushes the liquid to flow to the second chamber. The damping suffered by the roller is relatively large, and the exercise intensity of the user is improved. Wherein, in order to facilitate the flow of the liquid driven by the output shaft and also to seal the first chamber, a piston may be arranged at the inner end of the output shaft. Wherein, different numbers of cylinders are provided according to needs, so that when the user pulls the exercise rope, he can receive the resistance exerted by the damping device all the time, or receive the resistance exerted by the damping device at intervals.
