Description

A kind of pulley assembly with dustproof construction
Technical field
The present invention relates to a kind of pulley assembly, more precisely, being a kind of pulley assembly with dustproof construction.
Background technology
Roller is a kind of common industrial activity equipment, and the bottoms for being installed on housing, are moved easily more.Existing roller exists During rolling, easily dust and impurity are brought into the bearing arrangement above rolling wheel support, influence the service life of roller.
The content of the invention
The present invention mainly solves the technical problem present in the prior art, so as to provide a kind of pulley with dustproof construction Component.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals:
A kind of pulley assembly with dustproof construction, it is characterised in that the pulley assembly with dustproof construction includes one Fixing bracket, the support bracket fastened top are equipped with a rotatable fixed substrate, and the center of the fixation substrate is equipped with One first connected circular hole, the support bracket fastened afterbody are equipped with a movable locking plectrum, and the fixing bracket includes one To the stent intermediate plate being arranged in parallel, the support clamp on piece is respectively equipped with an intermediate plate circular hole, is set between the stent intermediate plate There is a dismountable roller, a connecting screw extends through the intermediate plate circular hole and roller, and is connected with an attaching nut, The support bracket fastened top is equipped with an outstanding dust cover, and the bottom of the dust cover is equipped with one second connection and justifies Hole, the dust cover is interior to be equipped with a separable dirt-proof boot, and the dirt-proof boot includes the dust-proof housing of a dish, described The bottom margin of dust-proof housing is equipped with the sealing flange of an annular, and the top of the dust-proof housing is equipped with one the 3rd connection and justifies Hole, a connection column cap extend through the 3rd connected circular hole, the second connected circular hole and first connected circular hole.
As preferred embodiments of the present invention, the dirt-proof boot is made of silica gel.
The pulley assembly with dustproof construction of the present invention has the following advantages:In use, using the dirt-proof boot in dust cover, It can effectively prevent the dust on roller to seal in the bearing on fixed substrate, substantially prolongs the roll wheel assembly uses the longevity Life.Once aging occurs for dirt-proof boot, as long as user is simply replaced, maintenance cost is cheap.Further, since dust cover It is outstanding so that dirt-proof boot does not influence the rolling of roller.The pulley block structure with dustproof construction is simple, positive effect, It is of low cost, it is highly practical.
