Abstract

A slip-proof split type chain wheel structure for bicycles and electric bicycles comprises a chain wheel sleeve (1) and a chain wheel (2), wherein the chain wheel sleeve (1) is of a three-tooth gear-shaped structure, and three teeth of the chain wheel sleeve (1) are embedded into the chain wheel (2); any tooth of the tooth disc sleeve (1) is cast with an opening (3), and a rivet (4) is pressed in the opening (3). The structure is stable, and the phenomenon of slipping is avoided unless the material is damaged, so that the gear failure caused by the traditional gear abrasion and brute force operation is avoided; and the manufacture, the assembly and the disassembly are more convenient, and the cost is saved.

Description

Anti-slip split type chain wheel structure for bicycle and electric bicycle

Technical Field

The utility model relates to a chain wheel structure, more specifically the utility model relates to a bicycle, electric bicycle are with preventing split type chain wheel structure of skidding that says so.

Background

At present, power acted on pedals in a manual driving system of an electric bicycle or the bicycle can be transmitted to a driving wheel through a rotating shaft, a split type chain wheel, a chain and a flywheel, so that a bicycle body moves forwards. The split type chain wheel comprises a chain wheel body and a chain wheel sleeve, the traditional chain wheel sleeve is square or circular, and after a gear is designed on the other side of the chain wheel sleeve and is embedded into the chain wheel through a cold heading technology, the gear at the other end is clamped to prevent the chain wheel sleeve from slipping. However, this structure is prone to gear failure due to gear wear and rough running, and is inconvenient to manufacture and assemble and disassemble and relatively costly.

Disclosure of Invention

An object of the utility model is to provide a bicycle, electric bicycle are with preventing split type chain wheel structure that skids to the above-mentioned problem that exists among the prior art.

In order to achieve the above object, the technical solution of the present invention is: the utility model provides a bicycle, electric bicycle are with split type chain wheel structure of preventing skidding, includes chain wheel cover and chain wheel, chain wheel cover be three-tooth gear shape structure, chain wheel cover three-tooth gear all imbed in the chain wheel.

Any tooth of the tooth disc sleeve is cast with an opening, and a rivet is pressed in the opening.

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

the utility model has the advantages that the special-shaped design of the three-tooth gear-shaped chain wheel sleeve is directly embedded into the chain wheel, the structure is stable, the sliding phenomenon can be avoided unless the material is damaged, and the gear failure caused by the traditional gear abrasion and the brute force operation is avoided; and the manufacture, the assembly and the disassembly are more convenient, and the cost is saved.

In the figure, a chain wheel sleeve 1, a chain wheel 2, an opening 3, a rivet 4 and a rotating shaft 5.

Detailed Description

The invention is described in further detail below with reference to the following description of the drawings and the detailed description.

Referring to fig. 1, the anti-slip split type chain wheel structure for the bicycles and the electric bicycles comprises a chain wheel sleeve 1 and a chain wheel 2, wherein the chain wheel sleeve 1 is of a three-tooth gear-shaped structure, and three teeth of the chain wheel sleeve 1 are all embedded into the chain wheel 2. The chain wheel 2 is fixedly arranged on a rotating shaft 5 of a manpower driving system through a chain wheel sleeve 1.

Referring to fig. 1, an opening 3 is cast on any tooth of the facing 1, a rivet 4 is pressed in the opening 2, and the rivet 4 can further prevent the facing 1 from rotating.

Referring to fig. 1, in the dental plate structure, a dental plate sleeve 1 is embedded into a dental plate 2 by using a special-shaped structure of the dental plate sleeve, and after the dental plate sleeve 1 is cold-headed to the dental plate 2, a rivet 4 is pressed into an opening 3 of one tooth, so that the dental plate sleeve 1 is further prevented from rotating. The structure is stable, and the phenomenon of slipping is avoided unless the material is damaged, so that the gear failure caused by the traditional gear abrasion and brute force operation is avoided; and the manufacture, the assembly and the disassembly are more convenient, and the cost is saved.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, above-mentioned structure should all be regarded as belonging to the utility model discloses a protection scope.

Claims
