Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of chain of easy for installation, easy maintenance.
For achieving the above object, the utility model provides following technological scheme: a kind of chain of easy disassembly, comprise chain link, described chain link is connected and composed by the half chain link symmetry that two take the shape of the letter U, the both ends of the surface of the U-shaped open at one end of described half chain link are provided with the fixture block that end face is swallow-tail form, the U-shaped open at one end of second half chain link described corresponds to fixture block place and is provided with the draw-in groove matched with fixture block, and the joint flip sleeve that described chain link corresponds to fixture block and draw-in groove is provided with the elastic reset part avoiding fixture block and exact separation.
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.
The utility model is set to further: described elastic reset part includes flip sleeve and is located at the retaining ring on chain link and is set on chain link and one end and be fixed on retaining ring, the other end is fixed on the elastic component on chain link, and described Fixing shrink ring is located on the position of fixture block and draw-in groove joint.
The utility model is set to further: described retaining ring is provided with near one end of the joint of fixture block and draw-in groove the block protruded towards chain link, described chain link is provided with the back-up ring protruded towards retaining ring, and back-up ring is positioned at one end place of retaining ring away from the joint of fixture block and draw-in groove, described elastic component is between block and back-up ring.
The utility model has following advantage: 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, improve the mechanical stability of chain.
