The utility model aims to provide a replaceable roller so as to solve the problem that the roller is inconvenient to replace.

In order to achieve the above purpose, the present utility model provides the following technical solutions: a replaceable roll comprising: the roller body and connecting axle, the symmetry is provided with the constant head tank on the roller body, the inside guide way that is provided with of connecting axle, the inboard slip of guide way is provided with the linking axle, the inboard at the constant head tank is pegged graft to the linking axle.

Preferably, a spring is arranged between the guide groove and the connecting shaft, and the connecting shaft is pushed to move outwards along the guide groove and is inserted into the inner side of the positioning groove through the elasticity of the spring.

Preferably, the inner side of the positioning groove is slidably provided with a supporting block, the supporting block is connected with the connecting shaft, and the supporting block moves along the positioning groove to abut against the connecting shaft to push the connecting shaft out of the positioning groove.

Preferably, the roller body is provided with a connecting pipe in a sliding manner, the connecting pipe is fixedly connected with the abutting block, and the connecting pipe moves along the roller body to drive the abutting block to move along the positioning groove.

Preferably, the inside strong magnet that is fixed with of linking axle, strong magnet with support piece fixed connection, the linking axle is supported the piece through strong magnet's magnetism and is prevented linking axle from coming off in the constant head tank.

Preferably, grooves are symmetrically formed in the connecting pipe, and the grooves are arranged to drive the connecting pipe to move along the roller body conveniently through abutting the supporting rod against the grooves.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the connecting pipe is pushed to move outwards along the roller body, and the abutting block is utilized to extrude the connecting shaft from the inner side of the positioning groove, so that the roller body can be taken out from the inner side of the mounting frame, and the roller body is convenient to detach and replace.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

Referring to fig. 1 and 2, an alternative roll is shown, comprising: the roller body 1 and the connecting shaft 6 are symmetrically provided with positioning grooves 2 on the roller body 1, the positioning grooves 2 are L-shaped square grooves, guide grooves 7 are formed in the connecting shaft 6, the guide grooves 7 are square grooves, connecting shafts 9 are slidably arranged on the inner sides of the guide grooves 7, and the connecting shafts 9 are spliced on the inner sides of the positioning grooves 2.

A spring 8 is arranged between the guide groove 7 and the connecting shaft 9, after the roller body 1 is installed, the connecting shaft 9 is pushed to move outwards along the guide groove 7 and insert into the inner side of the positioning groove 2 through the elasticity of the spring 8, and meanwhile, the positioning block 3 is abutted to prevent the positioning block 3 from moving along the positioning groove 2.
