Being operated first personnel pulls pull ring 145 to move down, and pull ring 145 moves downwards through bracing wire 143 and drives ratchet 142
To lower swing, ratchet 142 is not contacted to lower swing with ratchet 7, and second spring 146 is compressed, and stops drag pull ring 145, Ji Kela
Dynamic arc sleeve 131 moves down to contact with barbell with curved rod 132 to be fixed.When arc sleeve 131 and curved rod 132 are solid
After being scheduled on barbell, pull ring 145 is unclamped, because of the effect of second spring 146, ratchet 142, which is moved up, contacts engagement with ratchet 7,
Weight lifting personnel can start weight lifting, and during weight lifting, because of the effect of scroll spring 8, ratchet 7 is reversed on ratchet 142 and slides,
Meanwhile the cooperation of ratchet 7 and ratchet 142 can prevent from barbell from falling suddenly damaging weight lifting personnel.When needing to put barbell
When lower, pull ring 145 can be pulled to move down again, ratchet 142 is detached to lower swing and ratchet 7, because of the weight of barbell itself,
Barbell moves down recovery to original position, and unclamping again pull ring 145 makes ratchet 142 be swung up recovery to original position.
After the completion of weight lifting personnel's weight lifting, operator can pull motion bar 155 to be swung up, and motion bar 155 is upward
It swings and arc panel 156 is driven to be swung up, meanwhile, motion bar 155, which is swung up, drives fixture block 157 to slide in arc groove 158,
When fixture block 157 slides into 158 right end of arc groove, fixture block 157 is contacted with bar 1510, and then bar 1510 is matched with fixture block 157
It closes and fixes motion bar 155, be in contact with it, barbell can be put that is to say, bright arc panel 156 is swung up to barbell lower section
Under, barbell, which moves down, drives arc panel 156 to move down, and arc panel 156, which moves down, drives motion bar 155 to move down,
It is buffered because of the effect of third spring 153, when can be downward to barbell.After barbell is moved down with ground face contact, i.e.,
Bar 1510 can be pulled to move right, the 4th spring 1511 stretches, and bar 1510 moves right and do not contact with fixture block 157
It pulls motion bar 155 to drive arc panel 156 to restore to lower swing to original position to lower swing, bar 1510 can be unclamped, because of the 4th
The effect of spring 1511, bar 1510 are moved to the left recovery to original position.In this way, the excessive velocities that barbell can be prevented downward cause to lift
Weight personnel cannot make a response in time.
When initial, torque spring 18 is tensional state, when arc sleeve 131 is fixed on barbell with curved rod 132, behaviour
Making personnel can pull movable plate 17 to move right, and be detached from kelly 20 and card slot 19, because of the effect of torque spring 18, movable plate
17 are in a horizontal state to lower swing, and then when weight lifting personnel lift barbell, barbell is contacted with movable plate 17 and slipped over it, when
When barbell is fallen suddenly, movable plate 17 can block barbell.After the completion of weight lifting personnel's weight lifting, movable plate 17 can be pushed upward
Swing is caught in kelly 20 in card slot 19, unclamps movable plate 17.In this way, the safety fallen downwards to barbell can be reinforced.
When arc panel 156 and barbell contact, operator can haul handle 24, slowly make handle 24 to moving to left
Dynamic, handle 24, which is moved to the left, loosens wire 23, and because of the weight of barbell, barbell, which moves down, drives arc panel 156 to moving down
It is dynamic.When barbell moves down when being contacted with ground, handle 24 can be unclamped.In this way, can make operator more easily by barbell
It puts down.
