Abstract
The invention discloses a shackle which comprises a shackle main body and a connection piece, wherein the shackle is detachably connected; the shackle is characterized in that the shackle main body comprises two semi-closed main bodies with openings; connection lug bosses and/or connection grooves are formed in two opening ends of the semi-closed main bodies; the connection lug bosses are matched with the connection grooves; through holes are formed in the side walls of the connection lug bosses and the connection grooves; the two semi-closed main bodies are provided with two connection lug bosses and two connection grooves totally. Compared with the prior art, the shackle has the advantages that by the adoption of two matched structures consisting of the connection lug bosses and the connection grooves, the shackle is hinged through coaxial through holes; during use, the shackle can be opened only by dismounting any one of the hinged structures; a lifting rope can be put into the shackle or taken out of the shackle conveniently, so that the convenience in use is improved.
Description
Technical field
The present invention relates to hanging device field, be specially a kind of shackle.
Background technology
In modern architecture is produced, large-tonnage lifting is more and more, more and more higher to the requirement of hoisting connecting piece, requires reliability and durability.Current shackle great majority used are the shackle of D shape or bow shackle, and mode of operation is that D shape or arcuate section and bolt lift for steel rope, and constructional feature is bolt longer dimension, due to lifting circumstance complication, discontinuity causes a large amount of shackle distortion, causes dismounting difficulty, affects handling efficiency.
Summary of the invention
For above-mentioned technical matters, the invention provides a kind of simple in structure, easy to loading and unloading, the shackle that reliability is high.Concrete technical scheme is as follows:
A kind of shackle, comprise shackle main body and attaching parts, the detachable connection of shackle, is characterized in that: shackle main body comprises two semiclosed main bodys with opening, semiclosed main body two open ends have the boss of connection and/or connecting groove, connect boss and connecting groove and match; Connect boss and connecting groove sidewall and be provided with through hole; Two semiclosed main bodys have two connection boss and two connecting grooves altogether.
Preferably, two semiclosed agent structures are identical, and one of them open end of any one semiclosed main body has connection boss, and another open end has connecting groove.
Preferably, two semiclosed agent structures are different, and two open ends of any one semiclosed main body have connection boss, and two open ends of another semiclosed main body have connecting groove.
Preferably, semiclosed main body is bow shackle main body.
Preferably, semiclosed main body is D shape shackle main body.
Preferably, two semiclosed main body two ends are all articulated as one by bolt of rear end plate is detachable.
Preferably, two semiclosed main body one end are hinged by bearing pin, and the other end is articulated as one by bolt of rear end plate is detachable.
Preferably, semiclosed body cross-section is circular or oval or other arbitrary shapes.
Compared to existing technology, shackle of the present invention adopts the fit structure of two cover connection boss and connecting groove, hinged by coaxial through-hole, in use, as long as remove wherein any one articulated structure, just can open shackle, facilitate hoist cable to put into or exit, improved the convenience of using; In addition, with the shackle of traditional D shape, compare with bow shackle, as long as the bolt of rear end plate of this shackle meets the hinged requirement of coaxial through-hole, therefore length is shorter, not yielding, has strengthened reliability and the durability of shackle, can effectively reduce the damage rate of shackle, save cost.Overall structure is simple, safe ready, reliability are high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is bolt of rear end plate and arcuate main body connection diagram;
Fig. 3 is arcuate main body matching relationship schematic diagram in embodiment.
In figure: 1-arcuate main body, 11-connect boss, 12-connecting groove, 13-through hole, 2-bolt of rear end plate.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As Fig. 1, a kind of shackle, shackle main body is hinged by bolt of rear end plate 2, shackle main body is surrounded and is formed by two semiclosed main bodys with opening, semiclosed main body adopts arcuate main body 1, and arcuate main body 1 one of them open end has the boss 11 of connection, and another open end has connecting groove 12; Connection boss 11 and connecting groove 12 sidewalls are provided with through hole 13, two arcuate main body 1 and connect as one by inserting the bolt of rear end plate 2 of through hole 13 on two ends connection boss 11 and connecting groove 12 sidewalls, are class 8-shaped.
By upper, two arcuate main body 1 structures are identical, remove the bolt of rear end plate 2 of any one end of shackle, can open shackle, lay or remove hoist cable work.
Certainly, based on above-described embodiment, two arcuate main body 1 structures can also be different, and one of them arcuate main body 1 two ends is and connects boss 11, and another arcuate main body 1 two ends are connecting groove 12.Or two arcuate main body 1 one of them coupling end adopt non-removable bearing pin hinged, another coupling end adopts bolt of rear end plate 2 to connect, and also can realize object of the present invention; Or arcuate main body 1 can also replace with other forms of structure, D shape main body for example, as long as have two-end structure of the present invention, wherein one end is detachable hinged, can realize object of the present invention and all should think and belong to protection scope of the present invention; Arcuate main body 1 is regardless of shape of cross section in addition, can for circular, oval, there is the square of rounding or chamfering, or other do not affect arbitrarily the shape of using function.
Within not deviating from the scope of aim of the present invention, those of ordinary skills can according to above-mentioned specific embodiment by various be equal to replace obtain technical scheme, but these technical schemes all should be included in the scope of claim of the present invention and the scope that is equal within.
