By adopting technique scheme, when needing to be connected to form spendable chain between chain link, one end of the U-shaped opening of half chain link is arranged in corresponding, and fixture block is placed in draw-in groove, then by the sheathed fixation of elastic reset part, make it possible to fixing fixture block in draw-in groove, avoid the situation that fixture block comes off in draw-in groove, improve the mechanical stability between half chain link, and the using effect of chain can be improved, avoid the fracture of chain, coordinating and sheathed fixing by elastic reset part additionally by fixture block and draw-in groove, workman can be improved the efficiency coordinating chain is installed.
Chain link is divided into the first chain link and the second chain link, and the first chain link and the second chain link are cross-linked composition chain.All removably connected by fixture block and draw-in groove regardless of the first chain link and the second chain link, but wherein a kind of chain link i.e. half chain link of the first chain link is provided with groove away from the middle part of one end of U-shaped opening, this groove can use one end of clamping second chain link, and another first chain link of the other end clamping of the second chain link, groove has positioning action, and the second chain link is connected in this groove, just can with the clamping firmly of the first chain link, the chain be so cross-linked is not easy to change direction, convenient working.
Further, described chain link is provided with corresponding to the joint flip sleeve of fixture block and draw-in groove the elastic reset part avoiding fixture block and exact separation.
Further, described elastic reset part includes flip sleeve and is located at retaining ring on chain link, and be set in that on chain link and one end is fixed on retaining ring, the other end is fixed on elastic component on chain link, described Fixing shrink ring is located on the position of fixture block and draw-in groove joint.
Further, described retaining ring is provided with the block protruded towards chain link near the side of chain link, and described chain link is provided with the back-up ring protruded towards retaining ring, and back-up ring is away from the joint of fixture block and draw-in groove, and described elastic component is between block and back-up ring.
Further, described groove is made up of both sides joint and bottom, and described joint is connected with the both sides inwall of half chain link of U-shaped, and joint rounding, the joint rounding of described bottom and joint.
The utility model takes above-mentioned corrective measure to carry out, its beneficial effect is remarkable: coordinate by fixture block and draw-in groove the installation efficiency making it possible to improve workman, and by the cooperation between half chain link, make it possible to the length lengthening or shorten chain, improve the using effect of chain, by arranging retaining ring on chain link, and for spacing fixing fixture block and coordinating between draw-in groove, make it possible to the situation avoiding fixture block to come off in draw-in groove, between retaining ring and chain link, elastic component is set, the using effect of chain can be improved, and can automatically make retaining ring slide into the cooperation place of fixture block and draw-in groove, the positioning action of fit simultaneously, two chain link clampings are compacter and more stablely not easily move, improve the mechanical stability of chain.
