Abstract

The invention relates to a pin shaft easy to mount and demount. The pin shaft comprises a pin shaft body, a disc-shaped round head is coaxially formed at one end of the pin shaft body, an annular groove is formed at the other end of the pin shaft body, a mounting head is coaxially formed at the outer end of the annular groove, each of the upper end face and the lower end face of the mounting head is a plane, and each of the left side face and the right side face which connect the upper end face with the lower end face is a cambered surface. The pin shaft is reasonable in design, convenient to use, easy to manufacture and high in practicability, and by using the pin shaft, mounting and demounting efficiency can be improved, and great convenience is brought to working personnel.

Description

technical field [0001] The invention relates to a pin shaft in the field of chains, in particular to an easy-to-disassemble pin shaft. Background technique [0002] Chain is a kind of mechanical product with strong versatility. It is generally a metal link or ring, and it is mostly used for mechanical transmission. The chain is usually composed of links connected in sequence. Each link is composed of an outer link plate, an inner link plate, a pin shaft, a roller, and a sleeve. Both the outer link plate and the inner link plate are provided with through holes and pass through the pin shaft. connected. The end of the existing pin shaft is usually a round head. Since the round head is an interference fit, it is inconvenient to disassemble and assemble, resulting in prolonged working time. Contents of the invention [0003] The object of the present invention is to provide an easy-to-disassemble pin shaft with simple structure, easy manufacture and improved disassembly effi...
