Description

A horizontal bar with elastic pedals

technical field

The utility model belongs to the technical field of sports equipment, in particular to a horizontal bar provided with elastic pedals.

Background technique

Horizontal bar is a kind of common sports apparatus, all has very important significance for physical exercise and health-care exercise. People often use the horizontal bar to do pull-ups or hangs, which is helpful for stretching the body and rectifying the body, and can effectively develop the strength of the shoulders and arms. Among them, pull-ups are also one of the national physical exercise standard tests.

The existing horizontal bar is usually composed of two vertical bars and a cross bar mounted on the top of the two vertical bars. For people with poor strength quality of the shoulder straps and arms, the existing horizontal bar cannot effectively complete the complete hanging and pull-up exercises. Action, exercise effect is very limited, can not effectively exercise shoulder girdle arm strength.

Utility model content

The technical problem to be solved by the utility model is: aiming at the deficiencies in the prior art, provide a horizontal bar equipped with elastic pedals, which can adjust the elastic force of the elastic pedals, so that people with poor shoulder strap and arm strength quality can carry out vertical lifting. Hang to exercise the strength of the shoulders and arms, and then perform pull-up exercises, so as to effectively improve the strength of the shoulders and arms.

For solving the problems of the technologies described above, the technical solution of the utility model is:

A horizontal bar provided with elastic pedals, comprising two uprights and a cross bar arranged at the top of the two uprights, an elastic pedal is arranged between the two uprights below the cross bar, and the elastic pedals include a mounting base , the mounting base is provided with two height-adjustable uprights, the middle of the two uprights is fixed with a support base, and the tops of the two uprights are provided with pedals, located between the support base and the pedals Compression springs are sleeved on the two uprights;

A plurality of vertical rods are installed on the lower surface of the pedal, and some of the vertical rods are arranged around the two described columns. Compression springs are sleeved on the several of the vertical rods. The positioning block for axial movement of the rod, the compression spring is located on the vertical rod between the positioning block and the pedal, the cross section of the positioning block is circular and is provided with external threads, and the support base plate is provided with There are screw holes matched with the positioning block.

As an improvement, the positioning block is slidably fitted on the vertical rod, and the bottom end of the vertical rod is provided with a limiting member that restricts the positioning block from sliding out of the vertical rod.

As another improvement, the top of the vertical rod is fixedly connected with the support base plate, the positioning block is provided with a screw hole with an internal thread, and the vertical rod is threadedly installed in the screw hole of the positioning block, so The internal thread on the positioning block and the external thread have the same direction of rotation and the same pitch.

As a further improvement, the positioning block is provided with an adjustment handle for easy rotation of the positioning block.

Owing to adopting above-mentioned technical scheme, the beneficial effect of the utility model is:

Due to the elastic pedal, the installation base of the elastic pedal is provided with two height-adjustable columns, and the height of the elastic pedal can be adjusted by adjusting the height of the column to adjust the distance between the elastic pedal and the cross bar. Adapt to people of different heights.

Since the column is covered with a compression spring, the compression spring is offset against the supporting base plate and the pedal, which can provide a certain amount of elastic force to support the pedal. When in use, hold the cross bar and step on the pedal. The elastic effect of the board can form a certain support for the human body, reduce the force of the arm and shoulder muscles, and for people with weak shoulder and arm strength, it can also hang for a certain period of time, effectively exercise the strength of the shoulder and arm, and then complete the pull-up , to better improve the quality of shoulder girdle arm strength.

Since some vertical rods are installed on the lower surface of the pedal, compression springs are sleeved on several vertical rods, and positioning blocks that can move axially along the vertical rods are provided on the vertical rods, and the positioning blocks can be threadedly installed on the supporting base plate In the screw hole, the positioning block can be moved to install the positioning block in the screw hole of the support base, so that the compression spring on the vertical rod can squeeze the pedal, which can provide greater support for the human body and reduce the arm's strain when hanging With force, people with poor shoulder strap arm strength can also hang for a certain period of time, effectively training the shoulder strap arm strength quality, and can adjust the supporting force of the pedals according to specific conditions, adapting to different groups of people, and easy to use.

Because the positioning block is slidably sleeved on the vertical bar, the bottom end of the vertical bar is provided with a limit piece that restricts the positioning block from sliding out of the vertical bar, so it is convenient to adjust the positioning block.

Because the top of the vertical bar is fixedly connected with the support base plate, the positioning block is threadedly connected with the vertical bar, the internal thread on the positioning block is in the same direction of rotation as the external thread and the pitch is equal, the rotating positioning block adjusts the position of the positioning block on the vertical bar, and the screwing When the positioning block moves upward, the positioning block can be threadedly connected with the support base plate, and when the positioning block is screwed and moves downward, the positioning block can be separated from the support base plate, which is convenient for adjustment.

Since the positioning block is provided with an adjusting handle for easy rotation of the positioning block, the adjusting handle is applied with force to drive the positioning block to rotate during use, which is convenient and labor-saving to use.
