Respectively correspond installation axle sleeve in the symmetrically arranged support plate, shaft by axle sleeve be mounted on two support plates it
Between,
Master arm is fixedly connected in the shaft, master arm rear end is fixedly connected with load board, and rear end lower is provided with base
Plinth counterweight, the load board is perpendicular to master arm axis, and several loads hooks of load board rear side axis connection, front side is arranged hinged
Ear, load board lower part are provided with several limit spring seats, and limit spring seat is corresponding with load hook position, before and after limit spring seat
Two sides are equipped with limit spring, and rear side limit spring one end is connect with load hook front side,
The L-type limit plate is at an angle of and is composed of a fixed connection by No. 1 plate and No. 2 plates, and fixed connection place is provided with hingedly
Ring, hinge eyes, hinge ear are connected by pin shaft, and No. 1 plate of L-type limit plate is located above master arm, before No. 2 plates and corresponding position
The connection of lateral confinement position spring one end,
Described support arm one end is fixed with axle sleeve, and other end lower part is provided with counterweight, and axle sleeve is sleeved in shaft, the branch
Brace rear end and load hook cooperation,
The limited block is mounted between two support plates, is located at master arm and support arm lower part, for limit master arm with
Support arm,
The camshaft is mounted between two support plates, and camshaft one end is provided with knob, on camshaft protrusion with plus
Hook rear contact is carried, the wedge joint and disengagement of the protrusion control load hook on camshaft with support arm rear end.
The counterweight is tension spring, and the spring other end is fixed on the pedestal of support plate.
The counterweight is clump weight.
Fitness equipment load regulation mechanism of the invention, it is reasonable in design, transmission system is greatly simplified, equipment structure is made
It is simplified, reduces equipment volume, simultaneously because system is simplified, entire transmission system be can integrate in a lesser space
It is interior, it is rotated by knob when use, drives the cam axle of knob connection, the cam arranged on camshaft is pushed away with movement
It moves corresponding loading mechanism and makes different selections, connection and disconnection between different loads and master arm are controlled, to realize
Load number how many variation, has reached the adjusting of intensity of load.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is that camshaft of the present invention pushes load hook and support arm cooperating schematic illustration.
