Abstract
The utility model relates to a chain link plate with a square through hole. The chain link plate comprises a link plate body which is provided with two through holes including one circular through hole and the square through hole. The chain link plate is characterized in that one of the through holes is the square hole. The chain link plate is reasonable in design, the square through hole on the link plate body is matched with a chain pin shaft with a square head, runout of the pin shaft in the through hole of the link plate is effectively prevented, operation stability of a chain is improved, abrasion of the pin shaft from the link plate is avoided and the service life of the chain is prolonged.
Description
Technical field
The utility model belongs to field of chains, especially a kind of chain and chain-plate with square through hole.
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.The through hole that existing carrier bar surface is provided with is manhole, bearing pin also is circular and is inserted in the manhole of carrier bar simultaneously, because large load chain in the course of the work, bearing pin can produce play in manhole, therefore, 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 and chain-plate with square through hole 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 and chain-plate with square through hole comprises the carrier bar body, is provided with two through holes at the carrier bar body surface, and a through hole is manhole, and the another one through hole is square through hole.
Advantage of the present utility model and good effect are:
The utility model is reasonable in design, the carrier bar body is provided with square through hole and cooperates with the chain hinge pin with square head portion, 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 the chain hinge pin structural representation with square head portion that matches with the utility model;
Fig. 3 is that the A of Fig. 2 is to view.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
A kind of chain and chain-plate with square through hole as shown in Figure 1, comprises carrier bar body 2, is provided with two through holes at the carrier bar body surface, and a through hole is manhole 1, and the another one through hole is square through hole 3.
The utility model cooperates with the chain hinge pin with square head portion 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 hinge pin structure of square head portion as shown in Figures 2 and 3, this bearing pin comprises bearing pin body 5, this bearing pin body one end is provided with bottom 4, the other end of bearing pin body is provided with square head portion 6, on square head portion, radially be shaped with a bearing pin through hole 7, the square head portion of this bearing 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.
