When people need to train the lower edge of the pectoral muscles, first the staff makes the support mechanism 4 run according to the size of the people, and then the people stand between the two first support frames 3, and then adjust the adjustment mechanism 5 according to the height, and the people then Hold part of the support mechanism 4 with both hands, and then repeatedly do parallel bar arm flexion and extension exercises, and use the power of the pectoral muscles to move the body repeatedly up and down, so as to achieve the purpose of training the lower edge of the pectoral muscles. After people complete the training, people leave the support mechanism 4 and work The personnel stop the supporting mechanism 4 and return to the original position, and then adjust the adjustment mechanism 5 so that the adjustment mechanism 5 returns to the original position. If the device is used again, the above steps can be repeated.

In the initial state, the staff manually blocks the fourth support frame 45, and the first spring 48 is in a stretched state. When people need to train, the staff manually makes the fourth support frame 45 no longer block, and the first spring 48 Gradually reset from the stretched state, so that the fourth support frame 45 slides outward on the first slide rail 44, and the movement of the fourth support frame 45 drives the second slide rail 46 to move outward, and then the anti-slip sleeve 47 moves outward. When the distance between the two anti-slip sleeves 47 is enough for people to carry out training, the staff manually makes the fourth support frame 45 block again, and now the first spring 48 is in a compressed state or a stretched state, and then people stand on the two first springs. Between a support frame 3, adjust the adjustment mechanism 5 again, and then manually make the anti-slip sleeve 47 slide forward on the second slide rail 46 to a suitable position, then make the adjustment mechanism 5 fix the anti-slip sleeve 47, and then people use both hands Hold the two anti-slip sleeves 47 respectively, and then carry out the flexion and extension exercise of the parallel bars. After people complete the training, people adjust the adjustment mechanism 5 again, and then the anti-slip sleeves 47 are moved back to the original position, and then the adjustment mechanism 5 is restored to its original position. position, the staff makes the anti-slip sleeve 47 and the fourth support frame 45 move back to the original position inwardly, then fixes the fourth support frame 45, and the first spring 48 is stretched.

People manually make the positioning pin 52 slide outwards in the third slide rail 51 and the fourth support frame 45, and the second spring 53 changes from the initial state to a stretched state. When the positioning pin 52 is separated from the fourth support frame 45, people The anti-slip sleeve 47 is manually moved forward, and then the third slide rail 51 is moved forward, so that the positioning pin 52 is moved forward. When the anti-slip sleeve 47 is moved to a suitable position, people release the positioning pin 52, and the second spring 53 Stretched state is reset, and positioning pin 52 is moved inboard, and is inserted in the 4th bracing frame 45, and anti-slip cover 47 is fixed like this, thereby can prevent that anti-slip cover 47 moves arbitrarily when people train, and is relatively safe, waits for people to finish exercising Finally, people once again make the positioning pin 52 slide out to the outside in the fourth support frame 45, then the anti-slip sleeve 47 is moved back to the original position, so that the positioning pin 52 moves back to the original position, and people loosen the positioning pin 52 again. The spring 53 makes the positioning pin 52 move back to the original position inwardly.

People kneel on the support board 63, and then people perform the flexion and extension exercise of the parallel bars. When people's health moves downward, people's legs will push the support board 63 to move downward, and then the first slide block 62 will move downward on the fourth slide rail. 61 slides upwards and downwards, and when people's health moves upwards, the staff makes the first slider 62 and the support plate 63 upwardly move back to the original position, and now the support plate 63 has a certain supporting effect on people, thus achieving auxiliary training the goal of.

Under the training intensity that oneself can bear, people manually take off part of the counterweight 75 on the fifth bracing frame 74, or increase the counterweight 75 on the fifth bracing frame 74, and then train, when people utilize chest When pushing the support plate 63 downwards with force, the support plate 63 moves the first slider 62 downwards, and the first slider 62 drives the first connecting block 78 on the upper side to move downwards, and then pulls the first steel rope 79 , the first steel rope 79 is in contact with the guide wheel 77 and generates friction, the friction force makes the guide wheel 77 rotate, the guide wheel 77 plays a guiding role for the movement of the first steel rope 79, and at the same time the movement of the first steel rope 79 makes the first steel rope 79 on the lower side A connection block 78 moves upwards, and then the fifth support frame 74 slides upwards on the connection frame 73, and then the counterweight 75 moves upwards, so that the lower edge training effect of the chest muscles can be improved. When people's health moves upwards, the counterweight The block 75 moves back down due to gravity, causing the support plate 63 to move back up.

In the initial state, the first spring 48 is in a stretched state, and people manually rotate the handle 84 clockwise, thereby rotating the first rotating shaft 83, thereby rotating the reel 85 and releasing the second steel rope 86. At this time, the first spring 48 gradually resets from the stretched state, so that the fourth support frame 45 moves to the outside, and then the anti-slip cover 47 moves to the outside. When the distance between the two anti-slip covers 47 is enough for people to carry out training, people stop turning the handle 84, Make the anti-slip sleeve 47 stop moving, and then people train, while the first spring 48 is in the initial state or stretched state, because the friction force between the seventh support frame 82 and the first rotating shaft 83 is relatively large, the first spring 48 in the stretched state A spring 48 will not reset, and after people finish exercising, people manually make the handle 84 rotate in the opposite direction, and then the reel 85 winds up the second steel rope 86, so that the fourth support frame 45 and the anti-slip sleeve 47 rotate in the opposite direction. The inner side moves back to its original position and the first spring 48 is stretched.

When the support plate 63 moves downward, the support plate 63 drives the seventh slide rail 92 to move downward, and then the connecting rod 93 moves downward, so that the sponge cover 94 and the shifting block 96 move downward. The position block 91 cooperates, and the limit block 91 makes the shift block 96 move forward, and then the connecting rod 93 slides forward on the seventh slide rail 92, so that the sponge sleeve 94 moves forward, and the third spring 95 is moved forward by the initial state. Become compressed state, sponge cover 94 moves forward and presses down people's leg, can prevent people's health from shaking arbitrarily like this when training, and when support plate 63 upwards moves back to original position, makes sponge cover 94 and shift block 96 move upwards, Simultaneously, the third spring 95 resets from the compressed state, so that the sponge cover 94 and the shifting block 96 move back to their original positions.

Although the embodiments of the present invention have been shown and described, those skilled in the art can understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principle and spirit of the present invention. and modifications, the scope of the invention is defined by the appended claims and their equivalents.
