The application provides an embedded cardboard locking elevator round pin axle construction adopts following technical scheme:
the utility model provides an embedded cardboard locking elevator round pin axle construction, includes elevator body and cardboard, elevator body head and the tail both ends all are provided with the connector, the round pin shaft hole has been seted up to connector tip outer wall, connector one side tip outer wall sets up threaded hole, connector outer wall lower extreme is provided with the boss, the inside fixed pin axle of pegging graft in round pin shaft hole.
Through adopting above-mentioned technical scheme, insert two fixed pin axles with the fixed pin axle in proper order, rotatory fixed pin axle is with the draw-in groove towards the boss, put the cardboard into the clearance between draw-in groove and the boss, through the bolt with cardboard fixed mounting in connector upper surface to fix the fixed pin axle, can guarantee that fixed pin axle does not follow the axial float, also restricted fixed pin axle's rotation simultaneously, carry on spacingly through the boss to the cardboard simultaneously, compare with former single bolt fastening, the reliability is greatly improved.
Optionally, a clamping groove is formed in the outer wall of one end of the fixed pin shaft, and a shaft shoulder is arranged at the other end of the fixed pin shaft.
Optionally, the outer wall of the clamping plate is provided with a fixing hole with the same size as the threaded hole.
Through adopting above-mentioned technical scheme, through the fixed orifices with cardboard fixed mounting in connector outer wall.
Optionally, the outer wall of one side of the shaft shoulder is provided with a flat platform.
Through adopting above-mentioned technical scheme, design through the platform makes to have the clearance between shaft shoulder and the connector, and the rotatory shaft shoulder of being convenient for makes the angle of adjustment of fixed pin axle in assembling process easier.
In summary, the present application includes at least one of the following advantages:
1. one end of the clamping plate is matched with the clamping groove of the fixed pin shaft, so that the fixed pin shaft is prevented from moving along the axial direction, and the rotation of the pin shaft is limited.
2. The other end of the clamping plate is matched with the boss of the connecting body, so that the movement of the clamping plate is further limited; the clamping plate and the connecting body are fixed through the fastening bolts, the axial displacement of the clamping plate is limited, and compared with the fixation of an original single bolt, the reliability is greatly improved.
3. A platform is designed on the outer circular surface of the shaft shoulder of the fixed pin shaft, so that the angle of the fixed pin shaft can be adjusted more easily in the assembling process.
