Connector used for connecting chains in series

Abstract

The invention relates to a connector used for connecting chains in series. The connector used for connecting the chains in series comprises a connecting ring, the connecting ring is provided with an opening for allowing a chain link of an external chain to clamp into the connecting ring and hook parts positioned on two sides of the opening, the hook parts are used for being connected with the chain link of the chain, a gap space between two connecting ends of the connecting ring forms the opening, and the connector further comprises a locking piece detachably connected to the connecting ring.The locking piece can be connected with the two connecting ends of the connecting ring in a locking manner, so that the connecting ring is in a closed state at the opening position, and the two connecting ends of the connecting ring are locked together by the locking piece, so that the connecting ring is not easy to deform even if the connecting ring bears larger tension, the overall strength of the connector is effectively improved, and on the other hand, the locking piece is connected to the opening position of the connecting ring, so that the whole connecting ring is in a closed state, theproblem that the chain link of the chain fall off from the connecting ring is effectively avoided, and the use reliability of the connector is improved.

Description

technical field [0001] The invention relates to the technical field of chain accessories, in particular to a connector for connecting chains in series, wherein the chains can be anti-skid chains and animal husbandry chains, and the connector is especially suitable for animal husbandry chains. Background technique [0002] There are many functions of chains, anti-skid chains and animal husbandry chains are some of them. The car chain hook is a car safety accessory specially designed for the chain to be firmly tensioned on the tire tread. Using the structural characteristics of the hook to overcome the defects of the traditional vehicle chains that are easy to slide and loosen, to ensure that the structure of the vehicle chain is not deformed, it can be tightly and evenly attached to the tire tread, and to ensure the reliability of the vehicle chain. At present, the most common chain hook for vehicles is a crescent-shaped hook. The crescent-shaped hook includes two hook ears, ...

AI Technical Summary

Problems solved by technology

This structure has the following disadvantages: when the resultant force on the two hook lugs is less than the force on the tension buckle, the chain on the hook lug will slide by a large margin, because the openings of the two hook lugs are facing the same direction and Forms a large opening from which the chain can easily fall out during sliding

[0004] The S-shaped hook for vehicle chains in the above-mentioned patent still has certain deficiencies in actual use. Although it can prevent the chain from detaching from the lugs to a certain extent, due to the opening position of the two lugs of the S-shaped hook It is still not closed. During the driving of the vehicle, when the tension between the two chains is too large, the single hook ear is still prone to deformation. After a period of use, the opening position of the hook ear will gradually become larger, eventually causing the chain from The opening of the hook ear comes out
