Abstract
The utility model relates to the shackle of a kind of D type, comprise standard D flip shackle body and pivot pin, described pivot pin afterbody is provided with at least 2 fixed pin holes, and fixed pin holes circumferentially distributes same, is locked after D type shackle body and pivot pin are threaded connection with set pin again.Described set pin is spring cotter or has elastomeric R type pin.Fixed pin holes is 2, and its axis is orthogonal.Pivot pin head is provided with the locating shoulder of locating when being connected with D type shackle body, and locating shoulder opposite side establishes eye.Compared with prior art, the beneficial effects of the utility model are: 1) pivot pin afterbody establishes set pin, and can fix from different perspectives, connect safe and reliable, convenient, flexible; 2) pivot pin head has eye, need not special tool and detachable, easy to use; 3) changing rope in lifting can be temporary fixed by pivot pin, avoids threading off landing from D type shackle body; 4) be applicable to narrow space and require the occasion of easy accessibility, use safety.
Description
Technical field
The utility model relates to a kind of rigging attaching parts, particularly relates to a kind ofly be applicable to small space and require the D type shackle of easy accessibility, use safety.
Background technology
To when having the lifting weight of lifting ear to lift, the shackle of D type often can be used.The D type of current national standard and international standard unloads and is buckled with DW type and DX type, the pivot pin head of DW type shackle has eye, therefore just dismantled and assembled without special tool, but its pivot pin afterbody is just fixed by screw thread and shackle, the possibility loosened is there is, once pivot pin skids off because of thread looseness will cause safety misadventure there being the occasion screw thread fit of vibrations; The shackle of DX type after connecting with bolt, the pivot pin at clamp nut rear portion arranges set pin, its use safety, but the spanner needing dimension during dismounting, and extremely inconvenient in the occasion dismounting that usage space is narrow and small.
Summary of the invention
The utility model provides the shackle of a kind of D type, and its pivot pin head has eye, and afterbody establishes set pin, need not special tool and detachable, and connect safe and reliable, temporary fixed on shackle body of pivot pin can be realized, be applicable to narrow space and require the occasion of easy accessibility, use safety.
In order to achieve the above object, the utility model realizes by the following technical solutions:
The shackle of a kind of D type, comprise standard D flip shackle body and pivot pin, described pivot pin afterbody is provided with at least 2 fixed pin holes, and fixed pin holes circumferentially distributes same, is locked after D type shackle body and pivot pin are threaded connection with set pin again.
Described set pin is spring cotter or has elastomeric R type pin.
Described fixed pin holes is 2, and its axis is orthogonal.
Described pivot pin head is provided with the locating shoulder of locating when being connected with D type shackle body, and locating shoulder opposite side establishes eye.
Compared with prior art, the beneficial effects of the utility model are:
1) pivot pin afterbody establishes set pin, and can fix from different perspectives, connects safe and reliable, convenient, flexible;
2) pivot pin head has eye, need not special tool and detachable, easy to use;
3) changing rope in lifting can be temporary fixed by pivot pin, avoids threading off landing from D type shackle body;
4) be applicable to narrow space and require the occasion of easy accessibility, use safety.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1-Fig. 3, it is structural representation of the present utility model, the shackle of a kind of D type of the utility model, comprise standard D flip shackle body 1 and pivot pin 2, described pivot pin 2 afterbody is provided with at least 2 fixed pin holes 23, and fixed pin holes 23 circumferentially distributes same, be locked with set pin 3 again after D type shackle body 1 and pivot pin 2 are threaded connection.
Described set pin 3 is for spring cotter or have elastomeric R type pin.
Described fixed pin holes 23 is 2, and its axis is orthogonal.
Described pivot pin 2 head is provided with the locating shoulder 21 of locating when being connected with D type shackle body 1, and locating shoulder 21 opposite side establishes eye 22.
Shackle is a kind of rigging, is widely used because the little load capacity of its volume is large.Shackle conventional on home market is generally divided into GB, American Standard by production standard, marks three classes day; Wherein American Standard is the most frequently used.Unthreaded hole is established in open end one end of standard D flip shackle body 1, and the other end establishes tapped bore, and the afterbody of pivot pin 2 establishes screw thread, pivot pin 2 from after unthreaded hole one end D type shackle body 1 penetrates by being screwed at the other end.The eye 22 of pivot pin 2 head facilitates rotation to tighten pivot pin 2, and need not use special tool.
A kind of D type of the utility model unloads and is buckled in pivot pin 2 afterbody and establishes set pin 3, prevents from being threaded loosening, makes lifting more safe and reliable.Pivot pin 2 afterbody is same circumferentially establishes at least 2 fixed pin holes 23, its quantity can be 2 ~ 4, easily can realize fixing in all directions of set pin 3 like this, be particularly suitable for shackle usage space narrow and small or the occasion of set pin 3 cannot be inserted at a certain fixed-direction by field condition restriction.
In shackle working process; often there will be after a weight is fallen; original place lifts another weight; or the situation of more change steel rope is needed because Heave Here changes; now; only need pivot pin 2 tapped bore one end from D type shackle body 1 to exit, steel rope is taken out, and then other steel rope is put into just can again lift by crane.But because D type shackle body 1 other end is unthreaded hole, bearing pin 2 is easy to skid off from unthreaded hole come off, if aloft work, not only brings impact to construction, more there is the potential safety hazard of falling object from high altitude.Adopt the utility model, during in case of changed rope, only set pin 3 need be taken off, pivot pin 2 is exited from tapped bore one end, and then in the unthreaded hole other end and D type shackle body 1, set pin 3 is fixed on fixed pin holes 23, can realize the temporary fixed of pivot pin 2, flexible and convenient to use, practicality, safety are all very strong.
