when the athlete sits on the seat plate 2, the seat plate 2 and the tapered column 40 are pressed down by the weight of the athlete, and the tapered column 40 does not contact with the tapered slot 39 sufficiently, so that the rotation ring 38 and the first swing arm 3 and the second swing arm 4 can rotate freely.
An anti-rotation block 44 is fixedly installed on the outer wall of the pressing plate 41, the anti-rotation block 44 is arranged on the inner wall of an anti-rotation groove 45 in a sliding mode, the anti-rotation groove 45 is formed in the inner side wall of the vertical groove 42, and the pressing plate 41 can be prevented from rotating due to the sliding arrangement of the anti-rotation block 44 in the anti-rotation groove 45;
in this embodiment, a locking strip may be further disposed on an outer wall of the tapered post 40, and a locking slot may be disposed on an inner wall of the tapered slot 39, so that when the tapered post 40 is locked in the tapered slot 39, the position of the rotating ring 38 may be further locked, and the rotating ring 38 may be prevented from rotating.
The working principle and the using process of the invention are as follows:
when the lacing wire is needed, the body of a sportsman sits on the seat board 2, the two legs are respectively placed on the first swing arm 3 and the second swing arm 4, the sportsman can respectively swing the first swing arm 3 and the second swing arm 4 by controlling the rotation of the two knobs 16 with hands, so that the lacing wire can be freely performed, the left leg can be opened by swinging the first swing arm 3, the right leg can be opened by swinging the second swing arm 4, the two legs can be simultaneously opened, the lacing wire effect is better, the use is more convenient, and the upper half body does not need to do large-amplitude movement;
the first bevel gear 19 can be rotated by screwing the knob 16 through the rotating rod 18, the first bevel gear 19 rotates to drive the second bevel gear 20 meshed with the outer wall of the first bevel gear to rotate, the second bevel gear 20 rotates to drive the screw rod 21 to rotate, and the screw rod 21 rotates to drive the screw nut 23 in threaded connection with the outer wall of the first bevel gear to move up and down;
a first traction rope 26 is arranged between the top of the nut 23 and the first receiving roller 27, a second traction rope 33 is arranged between the sliding block 12 and the second receiving roller 32, the first receiving roller 27 and the second receiving roller 32 are connected through a first gear 29 and a second gear 30, and the arc-shaped spring 15 provides downward traction force for the sliding block 12 all the time;
when the nut 23 is in a stable position, the arc spring 15 pulls the slider 12 to pull the second pulling rope 33 to make the second receiving roller 32 and the second gear 30 tend to rotate, but because the position of the nut 23 is not changed, the positions of the first pulling rope 26, the first receiving roller 27 and the first gear 29 are also not changed, so that the first gear 29 and the second gear 30 are kept in a stable meshing state, and the slider 12 cannot move;
when the screw 23 moves downwards, the first traction rope 26 gradually stretches out of the first storage roller 27, so that the first storage roller 27, the first rotating shaft 28 and the first gear 29 rotate clockwise, the first gear 29 rotates clockwise to drive the second gear 30 meshed with the outer wall of the first gear to rotate anticlockwise, the second gear 30 rotates anticlockwise to also gradually release the second traction rope 33 on the second storage roller 32, the second traction rope 33 is released, so that the sliding block 12 can also be pulled by the arc-shaped spring 15 to move downwards, so that the first swing arm 3 or the second swing arm 4 rotates outwards, and the muscle-pulling exercise is facilitated;
when the first swing arm 3 or the second swing arm 4 rotates outwards to perform muscle stretching exercise, the athlete can also clamp the two legs forcefully so as to overcome the traction force of the arc spring 15 to enable the first swing arm 3 or the second swing arm 4 to move inwards, so that the muscle of the legs can be exercised conveniently;
when an athlete utilizes two legs to overcome the traction force of the arc-shaped spring 15 to enable the first swing arm 3 or the second swing arm 4 to move inwards, the second traction rope 33 is in a loose state at the moment, the nut 23 can be controlled to move upwards, the nut 23 moves upwards, the first storage roller 27, the first rotating shaft 28 and the first gear 29 lose the traction of the first traction rope 26 and can rotate anticlockwise under the action of the clockwork spring to tighten the first traction rope 26, meanwhile, the first gear 29 rotates anticlockwise to drive the second gear 30 to rotate clockwise, and the second gear 30 rotates clockwise to tighten the second traction rope 33 through the second storage roller 32, so that the first swing arm 3 or the second swing arm 4 is fixed at the position for the next use;
the blocking wheels 10 on the fixing frame 9 play a role in blocking, and when the two legs of the athlete are placed on the first swing arm 3 and the second swing arm 4, the blocking wheels 10 can block the two legs of the athlete, so that the two legs of the athlete can be effectively opened to carry out lacing wire exercise;
when the stretching amplitude of the two legs of the athlete exceeds the bearing capacity of the two legs of the athlete, the corresponding two legs also have inward thrust, at the moment, the two legs can push the pull rod 34 to move through the catch wheels 10 and the fixed frame 9, the pull rod 34 can compress the first spring 37 through the pull plate 35 when moving, the pressure of the two legs of the athlete is buffered by utilizing the displacement of the pull plate 35, and the injury to the athlete caused by the overlarge stretching amplitude of the two legs is prevented;
when the athlete does not sit on the seat board 2, the seat board 2 and the tapered column 40 are ejected out by the second spring 43, and the tapered column 40 is embedded in the tapered groove 39, so that the rotation of the rotating ring 38 and the first swing arm 3 and the second swing arm 4 can be prevented, the tension of the second traction rope 33 is effectively reduced, and the service life of the second traction rope 33 is prevented from being shortened due to damage caused by the fact that the second traction rope 33 is always pulled by the arc-shaped spring 15 and the sliding block 12;
when the athlete sits on the seat plate 2, the seat plate 2 and the tapered column 40 are pressed down by the weight of the athlete, and the tapered column 40 does not contact with the tapered slot 39 sufficiently, so that the rotation ring 38 and the first swing arm 3 and the second swing arm 4 can rotate freely.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
