Problems solved by technology

However, the muscles acquired through final motion load training have the following problems. Because of their weak flexibility and elasticity, they become the main cause of inability to perform necessary body movements in actual competitions, etc.
In addition, the terminal load training makes the parts that can be exerted less force, and the training is performed in a different movement state and output state than the actual movement, so there may be a problem of uncomfortable feeling in the body movement.
In addition, muscle tension hinders the supply of oxygen to muscle cells, and blood washout cannot be performed, so the produced lactic acid and other fatigue substances accumulate, causing problems such as muscle pain and fatigue to increase the burden on the body
Furthermore, there is a problem that muscle hardening becomes a major cause of failure

Embodiment 1

[0021] Such as Figure 1-4 As shown, a high pulley puller includes a swing arm 7, a fixed rod 20, and a counterweight box 4. The swing arm 7 is connected to the fixed rod 20 through a positioning pin 10, and the bottom end of the fixed rod 20 is connected to one end of the chassis 16. The other end of the underframe 16 is connected to the seat 2 through the seat bracket 17, the middle part of the underframe 16 is connected with the web 13 and the support pad 14 through the middle vertical rod 15, the underframe 16 is connected with the base 1 of the counterweight box 4, and the swing Arm 7 is connected to counterweight box 4 via pulley 9 and steel cable 6 . When the user pulls the swing arm 7 downward, the user's shoulders and arms pass the load of the weight box 4 transmitted through the tension member, and the grip part is loaded upward, so that the muscles near the shoulder girdle and the like It is "stretched" and at the same time resists the load of the counterweight box...

Embodiment 2

[0029] The working principle of the high-roller pull-down device of the present invention is: the top of the swing arm 7 of the present invention is connected with a holding body 8 that adopts a non-slip protective rubber sheath, the swing arm 7 is positioned on the fixed rod 20 through the positioning pin 10, and the bottom of the fixed rod 20 end is connected with one end of the underframe 16, the other end of the underframe 16 is connected with the seat 2 through the seat bracket 17, the middle part of the underframe 16 is connected with the web 13 and the support pad 14 through the middle vertical rod 15, and the outer periphery of the support pad 14 is covered The cushioning material, the position of the support pad 14 can be changed and selected through the positioning pin 19, which can stabilize the user and increase the safety factor. In order to increase the safety of training and improve the function and coordination of muscles and nerves, the material of the abdomina...

Abstract

The invention discloses a high pulley pull-down device, and belongs to the technical field of fitness equipment. The high pulley pull-down device comprises a swing arm, a fixed rod and a weight box. The swing arm is connected to the fixed rod through a positioning pin. The bottom end of the fixed rod is connected with one end of a bottom frame. The other end of the bottom frame passes through a seat support to be connected with a seat. The middle of the bottom frame is connected with an abdomen plate and a supporting cushion through a middle vertical rod. The bottom frame is connected with a base of the weight box. The swing arm is connected with the weight box through a pulley and a steel rope. The high pulley pull-down device has the advantages that the timing of relaxing, stretching and shortening of all muscle groups can be achieved, co-contraction is avoided, functions and harmony of nerves and muscles are improved, and soft and elastic muscles are obtained; the pull-down device is simple in structure, a user can adjust the magnitude of loads according to actual demands, activity injuries can not be easily caused, and the pull-down device is safe and reliable and can be easily operated without the aid of a trainer during training.

Description

technical field [0001] The invention belongs to the technical field of fitness equipment, in particular to a high pulley pull-down device. Background technique [0002] From the day of human birth, sports have been accompanied by its growth process. Early people's sports were mainly carried out outdoors, such as running, rowing, swimming, and later cycling, basketball, football, mountain climbing, skiing, etc. These sports can be collectively classified as outdoor sports. However, outdoor sports will be limited by time, space, climate, equipment, etc., and people cannot perform specific sports arbitrarily. This objective limitation stimulates the desire of human beings to conquer nature. People hope to break the limitation of objective conditions and carry out sports as they like. With the continuous development of material civilization, a group of mental workers began to explore in this area, studying how human beings can bring outdoor sports into indoors. The developmen...
