Abstract
The utility model relates to a chain pin shaft provided with a square head. The chain pin shaft provided with the square head comprises a pin shaft body, a bottom is installed at one end of the pin shaft body, the head is installed at the other end of the pin shaft body, and a pin shaft through hole is processed in the head along the radial direction. The chain pin shaft provided with the square head is characterized in that the shape of the head is square. The chain pin shaft provided with the square head is reasonable in design, the square head installed on the pin shaft body is matched with a link chain plate provided with a square through hole, the pin shaft is effectively prevented from shifting inside the through hole of the link chain plate, work stability of a chain is improved, the link chain plate is prevented from abrading the pin shaft, and service life of the chain is prolonged.
Description
Technical field
The utility model belongs to field of chains, especially a kind of chain hinge pin with square head portion.
Background technique
Chain is the stronger engineering goods of a kind of versatility, because it has gear and belt concurrently, therefore all is widely used at transmission, conveying and some special occasions.Chain is connected and composed successively by chain link usually, each chain link connects and composes by outer plate, inner plate, bearing pin, roller, sleeve, outer plate and inner plate are equipped with through hole and link together by bearing pin, and sleeve is installed outside bearing pin, be provided with roller and realize transmitting function between inner plate.It is circular that existing bearing pin is generally, in use, its head is inserted in the manhole of carrier bar and fixing, because large load chain in the course of the work, bearing pin can produce play in manhole, therefore, and its less stable, simultaneously bearing pin rotation meeting causes bearing pin damaged so that carrier bar produces to shear to bearing pin, has affected the working life of chain.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the chain hinge pin with square head portion of a kind of reasonable in design, stable performance and long service life is provided.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of chain hinge pin with square head portion comprises the bearing pin body, is provided with the bottom at bearing pin body one end, is provided with head at the other end of bearing pin body, radially is shaped with a bearing pin through hole on this head, this head be shaped as square head portion.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design, the square head portion that the bearing pin body is provided with also cooperates with the chain and chain-plate with square through hole, has effectively prevented bearing pin play in the carrier bar through hole, has improved the stability of chain work, the wearing and tearing of carrier bar to bearing pin have been prevented simultaneously, the working life of having improved chain.
Description of drawings
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is that the A of Fig. 2 is to view;
Fig. 3 is the chain and chain-plate structural representation with square through hole that matches with the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of chain hinge pin with square head portion as shown in Figures 1 and 2, comprises bearing pin body 2, is provided with bottom 1 at bearing pin body one end, is provided with at the other end of bearing pin body and is shaped as square head 3, radially is shaped with a bearing pin through hole 4 on this square head.
The utility model cooperates with the chain and chain-plate with square through hole and inner plate and outer plate can be linked together, and can effectively prevent bearing pin play in the carrier bar through hole.Has the chain and chain-plate structure of square through hole as shown in Figure 3, this chain and chain-plate comprises carrier bar body 6, be provided with two through holes at the carrier bar body surface, a through hole is manhole 5, the another one through hole is square through hole 7, in use, the square head portion of chain hinge pin is inserted in the square through hole of the square through hole of inner plate and outer plate, inserts the pin formation chain that inner plate, outer plate, sleeve, roller can be linked together in the bearing pin through hole.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other mode of executions that the technical solution of the utility model draws, belong to equally the scope of the utility model protection.
