Put in groove two, dirt-proof boot on the other hand can be coordinated to adsorb on opening.
This utility model is more preferably:Gap setting between one end of described roll shaft and roller set.
By adopting technique scheme, an end of roll shaft can make roller set with bearing rolling with the gap setting of roller set
When, just there is not friction with the roll shaft portion of being not in contact with roller set, thus allow maintaining roller set smoothly to rotate.
This utility model is more preferably:Another end of described roll shaft is provided with circular hole, is provided with bolt in circular hole, and
It is provided with pad between bolt and roll shaft.
By adopting technique scheme, bolt thus can be tightened by pad and a raised clamping frame or installation
Seat, roll shaft is fixed in frame or mounting seat.
By adopting technique scheme, this utility model hinge structure is compared:By the projection one on bearing
With spring collar one to the axial fixing bearing of cooperation, the spring collar two that roller puts and projection are same in the axial fixing bearing of cooperation
When also roller set is fixed, only need to take off spring collar two when dismantling, installing, by roll shaft pull-out can complete change, also set up
Spliced dust cap, and covered in roller by magnet absorption and connect, can either reach dust-proof effect it is also possible to fast quick-detach, peace
Dress, easy access.
