Abstract

The utility model discloses a kind of repeatedly used roll, including roll body, roll sleeve, lock collar and key, wherein, roll sleeve is sleeved on roll body, the edge at the both ends of the roll pedestal of roll body is provided with the first keyway, the second keyway is set with the correspondence position of the first keyway at the both ends of inner wall of roll sleeve, insert key after first keyway is corresponding with the second keyway, the centre of lock collar is provided with the stomidium for passing through the end of roll body, through hole is set in lock collar and corresponding screw hole is set in roll pedestal, is fixed lock collar and roll body by screw；By the suit of roll sleeve, roll body can be used for multiple times, reduce production cost, make resource rational utilization, meanwhile, by being used cooperatively for keyway and lock collar, it ensure that the stability of roll sleeve suit.

Description

A kind of repeatedly used roll

Technical field

Roll structure is the utility model is related to, more particularly to a kind of repeatedly used roll.

Background technology

After long-term use, surface has abrasion to roll, and causes to use, it is necessary to replace roll, so A large amount of wastes of resource can be caused, and production cost can be greatly improved.

Utility model content

The defect existing in the prior art for more than, the main purpose of the utility model is that overcome the deficiencies in the prior art Part, discloses a kind of repeatedly used roll, including roll body, roll sleeve, lock collar and key, wherein, the roll sleeve suit On the roll body, the edge at the both ends of the roll pedestal of the roll body is provided with the first keyway, in the roll sleeve The correspondence position of both ends and first keyway of inner wall the second keyway, first keyway and second keyway pair are set Should after be inserted into the key, the centre of the lock collar is provided with the stomidium for passing through the end of the roll body, in the lock collar Upper setting through hole simultaneously sets corresponding screw hole in the roll pedestal, by screw by the lock collar and the roll body It is fixed.

Further, the through hole in the lock collar at least sets 3, and corresponding screw hole is also provided with 3.

Further, the edge of the lock collar is between diametric(al) is in the inner and outer wall of the roll sleeve.

Further, the key is fixedly connected with the lock collar.

Further, the key is integrally formed with the lock collar.

Further, first keyway and the second keyway at least set one group.

Further, first keyway and the second keyway are provided with three groups.

The beneficial effect that the utility model obtains：

By the suit of roll sleeve, roll body can be used for multiple times, reduce production cost, make resource rationally sharp With change, meanwhile, by being used cooperatively for keyway and lock collar, it ensure that the stability of roll sleeve suit.

Embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with the accompanying drawings and implement Example is described in further detail the utility model.It should be appreciated that specific embodiment described herein is only explaining this reality With new, it is not used to limit the utility model.

As shown in Figs. 1-3, a kind of repeatedly used roll of the utility model, including roll body 1, roll sleeve 2, lock Disk 3 and key 4, wherein, roll sleeve 2 is sleeved on roll body 1, and the edge at the both ends of the roll pedestal 11 of roll body 1 is provided with First keyway 12, the second keyway 21, the first keyway 12 are set at the both ends of inner wall of roll sleeve 2 with the correspondence position of the first keyway 12 Insert key 4 after corresponding with the second keyway 21, makes roll body 1 not rotated against with roll sleeve 2, the first keyway 12 and the second key Groove 21 at least sets one group；Preferably, the first keyway 12 and the second keyway 21 are provided with three groups；The centre of lock collar 3, which is provided with, to be made The stomidium that the end 13 of roll body 1 passes through, through hole is set in lock collar 3 and sets corresponding spiral shell in roll pedestal 11 Hole, is fixed lock collar 3 and roll body 1 by screw；Through hole in lock collar 3 at least sets 3, and corresponding screw hole Set 3.

The edge of lock collar 3, so both can be with the shifting of blocks key 4 between diametric(al) is in the inner and outer wall of roll sleeve 2 It is dynamic, and can stop that roll sleeve 2 moves axially, to roll sleeve 2 with roll body 1 is opposing stationary plays dual fail-safe.

In another specific embodiment, more stablize to make key 4 be between the first keyway 12 and the second keyway 21, key 4 are fixedly connected with lock collar 3, it is preferred that key 4 is integrally formed with lock collar 3.

It these are only the preferred embodiment of the utility model, be not used for limiting the scope of the utility model；If The spirit and scope of the utility model are not departed from, to the utility model technical scheme is modified or replaced equivalently, should all be covered in this reality Among new scope of the claims.
