Abstract
The invention relates to a chain joint component comprising two joint chain pieces, two joint chain pins and a fastener. The two joint chain pieces are arranged to face each other in a spaced manner; the two joint chain pins penetrate through chain pin holes in the two ends of the two joint chain pieces correspondingly; the fastener is fastened to the two joint chain pins. A chain pin head portion is formed at one end of a chain pin rod body of each joint chain pin and an insertion connection end portion with a smaller diameter is formed at the other end of the chain pin rod body; the chain pin rod portions penetrate through chain pin holes of one joint chain piece and the insertion connection end portions penetrate through the chain pin holes of the other joint chain piece, so that a loose fit combination structure is formed. When the chain joint component is used for connecting the two ends of a chain unit assembly, the convenience of assembly is maintained; the joint chain pieces can be piece bodies identical with outer chain pieces, so that the die making cost is reduced.

Technical field
The present invention relates to a kind of chain, espespecially relate to the adapter assembly in a kind of chain
Background technique
The composition of one chain, it consists predominantly of most group chain unit and an adapter assembly, described majority group chain unit at least comprises two inner chain sheets, two outer chain sheets and a chain pin, described two inner chain sheets are oppositely arranged, one chain roller is set between the two, or directly form chain roller portion in described two inner chain sheet sides, described two outer chain sheets are relatively arranged on the outside of described two inner chain sheet one end, described majority group chain unit sequentially connects and forms the chain unit assembly of a strip, described adapter assembly then comprises two fitting chain sheets, two joint chain pins and a fastener, described fitting chain sheet is arranged at outside the inner chain sheet at described chain unit assembly two ends respectively, and be each passed through fitting chain sheet and inner chain sheet with described two joint chain pins, again with two joint chain pins described in fastener snapping, and make the chain of an annular.
In aforementioned chain composition structure, the fitting chain sheet of described adapter assembly is for ease of connecting into an annular link chain by the two ends of chain unit assembly, it must be loose fit state between fitting chain sheet and joint chain pin, be different from the chain sheet chain pin in chain unit and outer chain sheet drive fit kenel, the chain pin-and-hole aperture of the chain pin-and-hole in fitting chain sheet and outer chain sheet is not etc., make fitting chain sheet that another must be used to organize special mould to manufacture, therefore, the manufacture of fitting chain sheet and outer chain sheet has been come by two groups of different specialized moulds respectively, cause the Mold Making high expensive of chain entirety.
Summary of the invention
In order to solve in the chain joint assembly described in background technique, because fitting chain sheet is different from outer chain sheet, cause the problem of Mold Making high expensive, the invention provides a kind of chain joint assembly.
In order to achieve the above object, technical solution proposed by the invention is: provide a kind of chain joint assembly, it comprises:
Two fitting chain sheets, it is relative spacing arrangement, and described fitting chain two end part are respectively provided with a chain pin-and-hole;
Two joint chain pins, described joint chain pin respectively comprises a chain pin rod portion, and the chain pin head part be formed separately in two ends, chain pin rod portion and a grafting end, the diameter of chain pin head part is greater than the diameter in chain pin rod portion, and the diameter of grafting end is less than the diameter in chain pin rod portion, described two joint chain pins are respectively with the chain pin-and-hole of its chain pin rod portion through the fitting chain sheet in described two fitting chain sheets, the chain pin-and-hole that the grafting end of described two joint chain pins is arranged in another fitting chain sheet is loose fit, and described grafting end is stretched out outside another fitting chain sheet described; And
One fastener, it is arranged at outside another fitting chain sheet described, and is buckled on the grafting end of described two joint chain pins simultaneously.
Preferably, the fitting chain sheet in the chain pin rod portion of described two joint chain pins and described two fitting chain sheets is drive fit.
Preferably, the fitting chain sheet in the chain pin rod portion of described two joint chain pins and described two fitting chain sheets is loose fit.
Preferably, the section that the grafting end of described joint chain pin is stretched out outside another fitting chain sheet forms a catching groove, described fastener is U-shaped clip cramp, described U-shaped clamping cramp comprises two spaced engaging portion, and described two engaging portion are buckled in the catching groove of the grafting end of described two joint chain pins respectively.
In other words, chain joint assembly provided by the invention also has following preferred version:
In chain joint assembly as above, the fitting chain sheet in the chain pin rod portion of described two joint chain pins and described two fitting chain sheets is drive fit or loose fit.
In chain joint assembly as above, the section that the grafting end of described joint chain pin is stretched out outside another fitting chain sheet forms a catching groove, described fastener is U-shaped clip cramp, described U-shaped clamping cramp comprises two spaced engaging portion, and described two engaging portion are buckled in the catching groove of the grafting end of described two joint chain pins respectively.
The attainable beneficial effect of the present invention is: described chain joint assembly mainly utilizes waney structure sized by the chain pin rod portion of described two joint chain pins and grafting end, its two fitting chains sheet is enable to adopt the lamellar body being same as chain outside link, each joint chain pin is made to be arranged in described two fitting chain sheets, with the chain pin-and-hole of chain pin rod portion through one fitting chain sheet, be the composite constructions such as loose fit with the chain pin-and-hole of grafting end and another fitting chain sheet.Thus, when chain joint component application of the present invention is in time connecting the two ends of chain unit assembly, the chain pin rod portion of described two joint chain pins is arranged on a fitting chain sheet in advance and forms a joint member, again with described joint member two joint chain pin through the inner chain sheet being inserted in chain unit assembly two ends, another fitting chain sheet is socketed in loose fit mode on the grafting end of described two joint chain pins, again with the grafting end of fastener two joint chain pins described in snapping outside another fitting chain sheet described, described chain joint assembly is made to be connected at described chain unit assembly two ends and make a ring chain.Therefore, chain joint assembly of the present invention can maintain the convenience at its group chain unit assembly two ends, and enables fitting chain sheet select the lamellar body being same as outer chain sheet, uses same mould to manufacture, therefore reduces Mold Making cost.
On the other hand, in joint chain pin of the present invention, sized by its chain pin rod portion and grafting end, waney structure directly can complete in the manufacture process of joint chain pin, compare the manufacture of existing straight-bar type joint chain pin, class's formula that joint chain pin of the present invention forms grafting end in chain pin rod portion end undergauge constructs the problem not having manufacture cost and increase.And, the present invention makes joint chain pin be the chain pin head part that one end, chain pin rod portion forms larger external diameter, and be a T-shaped rod member with better intensity, so, joint chain pin is arranged between fitting chain sheet can provide excellent adhesive strength, and chain pin head part can be utilized to be resisted against outside friction tight fitting chain sheet, and more firmly combine to each other.
