The utility model aims to solve the problems and provides a backrest wheel.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a backrest wheel comprises a backrest wheel main body, a fixed wheel, a bolt, a round fastening piece, a shaft, a nut, a conical sleeve, a first screw hole, a shaft hole and a second screw hole.

The utility model discloses a back wheel, including back wheel main part, back wheel center line symmetry, the inside intermediate position of back wheel main part is equipped with the cone-shaped cover, the cone-shaped cover with the inner wall laminating and the both ends of back wheel main part are the opening setting, the level is provided with the axle in the cone-shaped cover, the left end tip cover of back wheel main part is equipped with the tight pulley, the upside and the downside of tight pulley are close to the tip position and follow the tight pulley center line symmetry is equipped with the screw No. one, the right side of tight pulley is equipped with circular mounting plate, the intermediate position of circular mounting plate is equipped with the shaft hole, on the circular mounting plate with a screw aligns and is provided with No. two screws, a screw with No. two screws pass through bolted connection.

Further, the fixed wheel and the backrest wheel main body are integrally formed.

Furthermore, the inner diameter of the first screw hole is the same as that of the second screw hole.

Furthermore, an opening is formed in the side face of the conical sleeve.

Furthermore, one end of the conical sleeve, which is far away from the fixed wheel, is provided with at least one key groove.

The utility model has the advantages that: simple structure, convenient to use, the toper cover has very strong elasticity, toughness, flexibility and elasticity, plays the effect of protection axle, makes things convenient for the dismantlement and the installation of axle, and circular mounting plate can the position of fixed axle, guarantees the normal work of back wheel, improves work efficiency, uses manpower sparingly and time cost.
