When people need to exercise the latissimus dorsi, firstly, people adjust the adjusting mechanism 5 according to the height of the upper half of the body, then people sit at the top of the seat 3, then the arms of people straighten, and the two hands grasp part of the adjusting mechanism 5, then the back is utilized to exert force to enable the adjusting mechanism 5 to operate, the adjusting mechanism 5 operates to drive the pull-down mechanism 4 to operate, then the two hands of people loosen the adjusting mechanism 5, enable the adjusting mechanism 5 to restore the original position, so that people enable the adjusting mechanism 5 and the pull-down mechanism 4 to operate repeatedly, thereby achieving the purpose of exercising the latissimus dorsi, after people exercise, the people enable the pull-down mechanism 4 and the adjusting mechanism 5 to restore the original position, and then leave the seat 3, if the equipment is used again.
When the adjusting mechanism 5 is operated, the adjusting mechanism 5 rotates the third supporting frame 43, and further rotates the first rotating shaft 42, thereby moving the barbell disc 44 upward, and then the person releases the adjustment mechanism 5 with both hands, the barbell disc 44 moves back into position due to gravity, thereby enabling the first rotating shaft 42 and the third supporting frame 43 to rotate back, meanwhile, the limiting frame 45 can prevent the third supporting frame 43 from rotating too much, in addition, the third supporting frame 43 makes the adjusting mechanism 5 operate to the adjusted state, the barbell plate 44 moves up and down to make the waist and the back of the person do repeated stretching movement, so as to exercise the latissimus dorsi of people, if people need to replace barbell plates 44 with different weights, people manually slide the barbell plates 44 outwards on the third supporting frames 43, it is then replaced and moved back into position, and the exercise is continued, after the person has finished exercising, the person moves the barbell disc 44 back down into position.
In the initial state, if a person cannot grasp the handle 53 with both hands when sitting on the seat 3, the person can manually slide the limiting rod 55 upwards in the fourth supporting frame 54 until the limiting rod 55 and the third supporting frame 43 are separated, at this time, the first spring 56 is changed from the initial state to the stretched state, then the person manually slides the handle 53 downwards, further the first slider 52 slides downwards in the first slide rail 51 and the third supporting frame 43, after the handle 53 moves to a proper height, the person loosens the limiting rod 55, the first spring 56 is reset from the stretched state, the limiting rod 55 moves downwards due to the elastic force, the limiting rod 55 and the third supporting frame 43 are matched again, further the handle 53 can be prevented from moving forwards and backwards, if the person can grasp the handle 53 with both hands when sitting on the seat 3, the height of the handle 53 does not need to be adjusted, then the person sits on the seat 3, arms stretch, and both hands respectively grasp the two handles 53, the handle 53 is pulled downwards by the back force, the first slide block 52 moves downwards, the first slide rail 51 moves to enable the third support frame 43 to rotate, the barbell disc 44 moves upwards, then the handle 53 is released by people, the barbell disc 44 moves back to the original position due to gravity, the handle 53 moves upwards, therefore, people pull the handle 53 downwards repeatedly, the latissimus dorsi is exercised, after the exercise is finished, people pull the limiting rod 55 upwards again, then the handle 53 is moved back to the original position manually, then the limiting rod 55 is released, and the first spring 56 enables the limiting rod 55 to return to the original position.
After people sit on the seat 3, the second rotating shaft 62 is manually rotated ninety degrees downwards, and then the sixth supporting frame 63 is rotated ninety degrees downwards, so that the central shaft 64 moves forwards and downwards, and then the sponge roller 65 is pressed on the thighs of people, thereby achieving the effect of pressing the legs, so that the exercise effect can be improved, after people take exercise, people rotate the second rotating shaft 62 back to the original position, so that the sponge roller 65 moves back to the original position, and then the two legs leave the sponge roller 65.
People make first rack 72 slide down on second slide rail 71 manually, second spring 73 becomes compression state by initial condition, then people take exercise, when first pivot 42 rotates, first pivot 42 can drive first gear 74 and rotate, wait for people to take exercise after, people loosen first rack 72, second spring 73 is reset by compression state, elasticity makes first rack 72 move back the normal position, first rack 72 and the meshing of first gear 74, when people change barbell piece 44, first rack 72 can prevent that first gear 74 from rotating at will, and then can prevent that third support frame 43 from rotating at will, and is comparatively safe.
When the air cylinder 83 is opened, the air cylinder 83 is operated to move the second rack 84 upwards, because the second rack 84 is meshed with the second gear 85, the second rack 84 moves to rotate the second gear 85 ninety degrees and further rotate the second rotating shaft 62 ninety degrees downwards, so that the sponge roller 65 presses the legs of a person, then the air cylinder 83 is closed, the thighs lift up the sponge roller 65 upwards, so that the sponge roller 65 moves upwards for a short distance, and further the second gear 85 rotates reversely, so that the second rack 84 moves downwards, and further the air cylinder 83 moves downwards, the air cylinder 83 moves to enable the second sliding block 82 to slide downwards on the third sliding rail 81, the third spring 821 is changed from an initial state to a compressed state, the second sliding block 82 moves to enable the first connecting rod 86 to move downwards, and further the first rack 72 moves downwards, and at the moment, the first rack 72 does not block the first gear 74, then, people do exercise for latissimus dorsi again, after people do exercise, people enable thighs not to abut against the sponge roller 65 any more, at the moment, the third spring 821 is reset from the compressed state, the first rack 72 is made to move back to the original position, the sponge roller 65 moves to the horizontal direction, people open the air cylinder 83 again, the second rack 84 is made to move back to the original position downwards, the sponge roller 65 is made to move back to the original position, and at the moment, people close the air cylinder 83, and the sponge roller 65 is made not to move any more.
People manually make third pivot 92 upwards rotate ninety degrees, and then make briquetting 93 upwards rotate ninety degrees, fourth torsion spring 94 becomes compression state by initial condition, people sit on seat 3 afterwards to lean on the waist on briquetting 93, people take exercise afterwards, briquetting 93 can make people utilize the rear portion better to exert oneself this moment, treat that people take exercise after the end, people loosen third pivot 92, fourth torsion spring 94 resets by compression state, make briquetting 93 and third pivot 92 turn back the normal position.
When the second rack 84 moves upwards, the second rack 84 drives the second wedge block 107 to move upwards, so that the first wedge block 106 moves forwards, the second connecting rod 103 slides forwards in the eighth supporting frame 102, the fourth rack 104 moves forwards, the fifth spring 105 changes from the initial state to the stretching state, the fourth rack 104 moves forwards to enable the third gear 101 to rotate, the third rotating shaft 92 rotates upwards by ninety degrees, and the pressing block 93 rotates upwards by ninety degrees due to the fact that the fourth rack 104 is meshed with the third gear 101, the purpose of automatic rotation is achieved, when the second rack 84 moves back downwards to the original position, the first wedge block 106 is separated from the second wedge block 107, the fifth spring 105 is reset from the stretching state, the fourth rack 104 is reset, and the third gears 101 and the pressing block 93 reversely rotate back to the original position.
It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by using equivalent alternatives or equivalent variations fall within the scope of the present invention.
