In the time of need unloading scale pan, only need push rod is pushed away in sleeve, under the promotion on the truncated cone-shaped inclined-plane of push rod termination, securing rod can be pushed in the withdrawal bar hole, and can take off scale pan easily this moment from sleeve.In the time of scale pan need being installed, the outer end of scale pan being aimed at push rod inwardly pushes away, under the effect on inclined-plane, push rod outer end in the securing rod withdrawal bar hole, when scale pan is moved on the fixed via position, unclamp push rod, and rotate scale pan and align with fixed via, at this moment until the bar hole, securing rod inserts in the fixed via under the promotion of microsprings, with the position relation locking of scale pan and sleeve.
Adopt such scheme, can reach following effect:
1. use the present invention installs and unloads scale pan and compare very efficient and convenient with traditional helicitic texture.
2. because scale pan is not to rely on screw thread to be fixed on the lever, therefore in the process of lifting or placing down the weight, no matter produce great moment of torsion, scale pan all can't slide from lever.So just eliminated the potential safety hazard that causes because of the scale pan landing in the barbell exercise.
3. because securing rod is mutually 120 ° of circle distribution, make the latching force equilibrium between scale pan and the sleeve, locking effect is better.
