Abstract

The utility model discloses a chain link crosspiece with two ends serving as arc contacting surfaces for a chain link. A saddle-shaped protrusion is formed in the middle of each arc contacting surface. The chain link crosspiece has the advantage that since the protrusions are obviously formed in the middle of the arc contacting surfaces, contacting the chain link, of the crosspiece, and two ends of the crosspiece are lower to form angles, the middle part pressed into the chain link is far deeper than the two ends after the crosspiece is pressed into the chain link, so the crosspiece is fixed with the chain link more reliably. And the chain link crosspiece is simple in structure and far lower in loosening or falling off rate.

Description

A kind of cable stud

Technical field

The utility model relates to a kind of cable stud.

Background technique

It is the major part of marine anchor chain that grade common link is arranged, and shown in accompanying drawing 1-3, the size of its contact arc surface of the crosspiece in the middle of chain link R changes along with the chain link sized; As far as the crosspiece of same nominal size, the internal surface of arc surface should be a smooth, and the size of its H1 should be in the tolerance range of regulation; That is to say, after crosspiece is pressed into chain link, only if crosspiece is when putting into the chain link inboard; The putting position deviation, its compression distance should be very nearly the same.Crosspiece is mainly used in the strength and stiffness that improve chain link; Therefore; Electric welded anchor cable NBS peculiar to vessel and various countries classification society rule all require crosspiece will be fixed on the central authorities of chain link reliably; For preventing that crosspiece is in use loosening or coming off, after being pressed into chain link, the crosspiece of NBS and the regulation M3 of classification society rule level marine anchor chain should adopt manual electric arc welding, non-flash one end of welding crosspiece.This design and the effect that make to require are more obvious, but there are size deviation in chain link and crosspiece in the process of manufacturing, and crosspiece is pressed into still can not avoid occurring that tightness differs even gapped phenomenon behind the chain link.Therefore, though adopt manual electric arc welding reinforcement of weld M3 level marine anchor chain crosspiece, still can not stop anchor chain in use for some time, indivedual crosspieces become flexible or come off.For the mooring cable chain link, its crosspiece is to realize fixing through increasing with the area of contact of chain link and the plastic deformation of compression distance and chain link, and is comparatively complicated.

The model utility content

The model utility purpose: to the problems referred to above, the purpose of the utility model provides a kind of cable stud loosening or that come off of fixing reliably, prevent.

Technological scheme: a kind of cable stud, two ends are and the arc surface that contacts of chain link that said contact arc surface centre forms the convexity of saddle.

Beneficial effect: compared with prior art, the utility model has the advantages that crosspiece forms in the middle of the arc surface significantly protrudingly with a chain of the contact, two is low slightly; Shape at an angle; After crosspiece was pressed into chain link, the degree of depth that the intermediate projections position is pressed into chain link far surpassed crosspiece two, and is fixing reliable with chain link; Simple in structure, the loosening or probability that comes off reduces greatly.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiments only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.

Like accompanying drawing 4, shown in 5, a kind of cable stud, two ends be with chain link contact arc surface 1, form the convexity 2 of saddle in the middle of the contact arc surface 1.Contact arc surface 1 smooth surface, but in the middle of obviously protruding, two is low slightly, shape at an angle, maximum is no more than 9 °, the size of R1 changes along with the chain link sized, with same specification existing technology middle rail to contact arc surface R measure-alike.After crosspiece was pressed into chain link, the degree of depth that the intermediate projections position is pressed into chain link far surpassed crosspiece two.

Claims

1. cable stud, two ends be with chain link contact arc surface (1), it is characterized in that: the convexity (2) that forms saddle in the middle of the said contact arc surface (1).
