Description

Strength training device for physical exercise Technical Field

[0001] The present invention relates to the technical field of sports equipment, in particular to a strength training device for physical exercise. Background Art

[0002] Physical exercise refers to physical activities that people choose based on their physical needs, use various sports methods, and combine natural forces and hygiene measures to develop the body, improve health, enhance physical fitness, regulate the mind, enrich cultural life and manage leisure time. It is generally divided into horizontal bars, parallel bars, dumbbells, etc., among which the horizontal bar is usually used for pull-ups and other movements to exercise the upper limbs, back and core muscles.

[0003] However, when performing pull-ups on existing horizontal bar equipment, the entire center of gravity needs to be placed above the horizontal bar. This movement process will cause the horizontal bar to shake slightly. After performing pull-ups for a long time, there may be a safety risk that the horizontal bar will break or loosen, affecting the life safety of the trainees. At the same time, a large amount of sweat will be generated on the hands during training. The sweat will reduce the friction of the hands and cause signs of falling off, causing harm to the trainees. Technical issues

[0004] In view of the deficiencies in the prior art, the present invention provides a strength training device for physical exercise to solve the problems mentioned in the above background technology. Technical Solutions

[0005] The top end face of the lifting link is fixedly provided with a lifting power of 1.5 years, and the lifting power is 2.5 years that of the lifting link is lifted in the up-down knob.

[0006] As a preferred technical solution of a strength training device for physical exercise described in the present invention, the extrusion assembly includes a plurality of partitions fixedly connected around the bottom of the inner wall of the hexagonal shell. During the pull-up process, excessive movement will cause the horizontal bar seat to shake. During the shaking process, it will tilt. The extrusion force caused by the tilt will push the bent rod to move up and down. The up and down movement of the bent rod will drive the rotating rod to move, and the rotating rod will drive the fixed wheel to move. Therefore, the stability of the device is enhanced by the provision of multiple fixed wheels, and the damage of the device due to violent movement is prevented. The movement of the fixed wheel will squeeze the lifting plate, and the lifting plate is squeezed and drives the extrusion plate to move. When the exercise is carried out, the extrusion plate squeezes the annular bag, and the reset spring is provided so that the extrusion plate can squeeze the annular bag differently during the exercise. The annular bag is squeezed, and the generated air flow moves to the inside of the first rubber sleeve through the provided elbow. The air flow is exhausted through multiple air holes provided at the first rubber sleeve, thereby reducing the sweat generated on the hands of people when exercising. The joint action of the provided first rubber sleeve enhances the anti-slip effect of the device, improves the safety of people, and enhances the protection effect. A lifting plate is slidably connected between the two partitions, and the two ends of the bottom of the lifting plate are respectively fixedly connected to reset springs, and the bottom of the reset spring is fixedly connected to the bottom of the inner wall of the hexagonal shell.

[0010] As a preferred technical solution of a strength training device for physical exercise described in the present invention, the cleaning component includes arc-shaped sleeves respectively sleeved and slidably connected to the two ends of the inner wall of the second rubber sleeve. When the exercise is finished, the inside of the first rubber sleeve is no longer squeezed, the air pressure returns to normal, and the auxiliary spring rebounds, driving the arc-shaped sleeve to move in the opposite direction. Due to the elastic effect of the auxiliary spring, the protective component will move repeatedly. The setting of the auxiliary sliding sleeve and the cleaning cotton block can repeatedly clean the inner surface and the outer surface of the first rubber sleeve, thereby reducing the adhesion of sweat in the first rubber sleeve, preventing the odor and stickiness caused by long-term adhesion of sweat, and improving the attractiveness of the device. Several auxiliary springs are fixedly connected around one end of the arc-shaped sleeve, the inner wall of the arc-shaped sleeve is sleeved and fixedly connected to the first magnetic ring, and the inner walls of the two ends of the inner cavity of the first rubber sleeve are slidably connected to the second magnetic ring.

During use, when a person is exercising, he places his hand on the outside of the first rubber sleeve and grasps it. The force generated by the grasping squeezes the second rubber sleeve, causing the second rubber sleeve to deform, and the internal airflow generates movement, and the airflow pushes the two arc-shaped sleeves outward, and the arc-shaped sleeve drives the first magnetic ring to move, and the magnetic force of the first magnetic ring drives the second magnetic ring to move, and the second magnetic ring drives the auxiliary sliding sleeve to move, and the second magnetic ring drives the connecting rod to move, and the connecting rod drives the circular plate to move, and the circular plate drives the cleaning cotton pieces to move, and the circular plate drives the reinforcement rod to move, and the reinforcement rod is aligned with the circular hole set on the disc, thereby enhancing the overall stability of the device, reducing the shaking caused by pull-ups, and preventing the device from being damaged. Beneficial effects

[0014] (1) When in use, when a person is exercising, he places his hand on the outside of the first rubber sleeve and grasps it. The force generated by the grasp squeezes the second rubber sleeve, causing the second rubber sleeve to deform and the internal airflow to move. The airflow pushes the two arc sleeves outward, and the arc sleeve drives the first magnetic ring to move. The magnetic force of the first magnetic ring drives the second magnetic ring to move.

The circular plate drives the cleaning cotton block to move. The circular plate drives the reinforcing rod to move. The reinforcing rod is aligned with the circular hole set on the disc, thereby enhancing the overall stability of the device, reducing the shaking caused by pull-ups, and preventing the device from being damaged.

[0015] (2) During the pull-up process, excessive movement will cause the horizontal bar seat to shake. During the shaking process, it will tilt. The squeezing force caused by the tilt will push the bent rod to move up and down. The up and down movement of the bent rod will drive the rotating rod to move, and the rotating rod will drive the fixed wheel to move. Therefore, the stability of the device is enhanced by the multiple fixed wheels, which prevents the device from being damaged due to violent movement. The movement of the fixed wheels will squeeze the lifting plate. The lifting plate is squeezed and drives the squeezing plate to move. The squeezing plate squeezes the annular bag. The reset spring can make the squeezing plate squeeze the annular bag differently during the movement. The annular bag is squeezed, and the air flow generated by the squeezing moves to the inside of the first rubber sleeve through the set bend pipe. The air flow is exhausted through the multiple air holes set on the first rubber sleeve, thereby reducing the sweat generated on the hands of people during exercise. The anti-slip effect of the device is enhanced in conjunction with the set first rubber sleeve, which improves the safety of people and enhances the protection effect.

[0016] (3) When the exercise is finished, the interior of the first rubber sleeve is no longer squeezed, and the air pressure returns to normal. At the same time, the auxiliary spring rebounds, driving the arc sleeve to move in the opposite direction. Due to the elastic effect of the auxiliary spring, the protective component moves repeatedly. The setting of the auxiliary sliding sleeve and the cleaning cotton block can repeatedly clean the inner surface and the outer surface of the first rubber sleeve, thereby reducing the adhesion of sweat in the first rubber sleeve, preventing the odor and stickiness caused by the long-term adhesion of sweat, and improving the attractiveness of the device.
