Description

Chain with roller capable of being replaced quickly

Technical Field

The present invention relates to a chain, and more particularly, to a chain in which rollers can be quickly replaced.

Background

The chain of the bucket conveyor is used for mechanical transmission between a motor and a roller of the bucket conveyor, is generally a metal chain ring or a metal ring, is mainly used for mechanical transmission and traction, has the advantages of high bearing capacity, suitability for severe working environment, high transmission efficiency and small force acting on a shaft, and is widely applied to the bucket conveyor.

Some tiny parts in the prior art can be directly transmitted through a chain, a rotating roller is usually sleeved on the chain, and an anti-slip sleeve made of rubber materials is sleeved outside the rotating roller. After long-term work, because the antiskid cover is collided by the part all the time, easy deformation is impaired, leads to some antiskid cover can't contact the part, does not play the effect of transmitting the part, is infected with the dust too much moreover, can make dirty the part. At this time, the antiskid sleeve needs to be detached and replaced or cleaned, but the chain needs to be detached and cleaned due to the fact that the rotating roller is clamped between the chain plates, and the problem of complex detachment exists.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide a chain with rollers capable of being replaced quickly, and the chain has the effect of being convenient to disassemble.

In order to achieve the technical purpose, the invention provides the following technical scheme: the utility model provides a chain that roller can be swiftly changed, includes two outer link plates, every the inboard fixed mounting of outer link plate has the inner plate, the front surface fixed mounting of outer link plate has the thread tightening pin, the plain end fluting has been seted up to the front surface of thread tightening pin, the rear surface fixed mounting of outer link plate has the thread bush, fixing pin and thread bush threaded connection, the inboard movable mounting of inner plate has the rotation roller, it is equipped with annular anti-skidding cover to rotate the roller overcoat, the anti-skidding cover adopts stereoplasm rubber to make, set up jaggedly on the anti-skidding cover, the vertical extension has the interior swivel nut that inserts the breach on the rotation roller lateral wall, it is provided with the housing screw with interior swivel nut threaded connection to rotate the roller, the nut of housing screw is used for compressing tightly the both ends of anti-skidding cover breach.

Preferably, concave arc-shaped yielding grooves are formed in two ends of the notch of the anti-slip sleeve respectively, and the inner sleeve is attached to the yielding grooves.

Preferably, the outer side walls of the two ends of the notch are provided with arc-shaped positioning grooves, the outer periphery of a screw cap of the screw vertically extends downwards to form a circular positioning ring, and the positioning ring is attached to the positioning grooves and rotates.

Preferably, the outer end face of the screw is located inside the outer wall of the anti-slip sleeve.

In summary, the present invention achieves the following effects:

1. by means of the cooperation of the anti-skidding sleeves, the inner screw sleeves and the screws, the anti-skidding sleeves are quickly installed and detached.
