Description

Arm strength exercising equipment

Technical Field

The utility model relates to an exercise technical field specifically is an arm strength exercise equipment.

Background

The arm strength exerciser is also called a holding rod and is used for exercising arm muscle groups, mainly exercising arm strength and pectoral muscles and assisting in exercising wrist strength. The arm power exerciser is a sports apparatus for forearm wrist flexor, and has certain danger. The force required for use is classified into different levels, generally into several levels of 20, 30, 40, 50, 60, 80, 100 and 110KG, which are the force required for bending the arm exerciser. The existing arm strength exerciser needs to be selected according to different levels when in use, but the level needs to be changed after long-time exercise, but the cost is high, and the arm strength exerciser is easy to get rid of hands and hurt people when in use, so that certain danger exists.

SUMMERY OF THE UTILITY MODEL

Not enough to the above-mentioned that prior art exists, the utility model provides an arm strength exercise equipment.

The utility model provides a following technical scheme: an arm strength exercising device comprises a supporting arm, a connecting seat, a swinging arm and a tension spring;

the support arm is installed on the connecting seat, and the swing arm is equipped with two and rotates with the connecting seat through the connecting axle to be connected, install the screw rod on swing arm and the support arm, install the different tension spring of multiunit length through the screw rod between swing arm and the support arm.

Preferably, the other end of the swing arm is provided with an anti-slip handle.

Preferably, the section of the connecting seat is U-shaped, the connecting seat is arranged in the middle of the supporting arm, and the swing arms are symmetrically distributed on the connecting seat through the connecting shaft.

Preferably, the tension spring comprises a spring, a threaded sleeve and connecting rings, two ends of the spring are respectively connected with the two connecting rings, the connecting rings are arranged on the end face of the threaded sleeve, and the threaded sleeve is in threaded connection with the screw.

Preferably, the groups of tension springs with different lengths are installed to be kept parallel.

Compared with the prior art, the utility model discloses possess following beneficial effect:

this arm strength exercise equipment, assemble the tension spring assembly that multiunit length is different between swing arm and support arm, utilize multiunit tension spring to increase the pulling force of swing arm, and assemble the tension spring of different quantity, the pulling force of adjustable swing arm, so that adjust, and after the later stage adaptation, can be continuous increase tension spring, increase the degree of difficulty, this arm strength exercise equipment mainly tears two swing arms with the fingers and thumb in addition, the support arm has the effect that blocks the swing arm after taking off the hand, launch the back support arm and collide with the people in advance, so the injury is less, the security is higher.
