Abstract

The invention discloses a shackle, and provides the shackle which has the advantages that a hinge pin can be fixed on a shackle hole quickly and conveniently to enable articles to be hoisted, without a thread, or the hinge shaft is pulled out of the shackle hole to enable the articles to be unloaded. The shackle adopts the structure that a pair of pin bulges is arranged on the external cylindrical surface of the head of the hinge pin, a circular through hole and a pair of through grooves distributed symmetrically are formed in the shackle hole, the hinge pin and the pair of pin bulges in the hinge pin penetrate the circular through hole and the through grooves, then the hinge pin is rotated for 90 degrees, the pin bulges enter another pair of blind grooves, distributed symmetrically, in the shackle hole, the pin bulges cling to the blind grooves by virtue of a spring in the handle part of the hinge pin, and the hinge pin is fixed on the shackle hole through locking; and in unloading, the handle part of the hinge pin is pressed, so that the pin bulges leave from the blind grooves, and then the hinge pin is rotated for 90 degrees, so that the hinge pin penetrates the circular through hole and the through grooves to be withdrawn from the shackle hole. The shackle is suitable for hoisting a lifting appliance.

Description

Shackle

Technical field

The present invention relates to a kind of rising reuses part, especially relate to hoisting sling.

Background technology

Existing lifting shackle, is made up of button, buttonhole, bearing pin etc., and buttonhole and button have rib-loop to connect, and lift by crane article, bearing pin need to be passed through buttonhole, and outer for head rib-loop is screwed into rib-loop in buttonhole；Unload and bearing pin need to be turned on rib-loop during thing, waste time and energy, reduce the utilization rate of hoisting machinery.

Content of the invention

The present invention overcomes the above-mentioned deficiency of prior art, provides a kind of easy and simple to handle quick, the shackle that just can fix bearing pin with buttonhole without rib-loop or separate them.

The present invention adopts the following technical scheme that：A kind of shackle, is made up of button, bearing pin, buttonhole, spring etc. and there is symmetrical a pair of pin to dash forward on bearing pin head external cylindrical surface, its cross section is rectangle；Relative to having a pair logical groove, also a pair symmetrical blind groove on the prominent position of the pin of bearing pin head on buttonhole, the axis of this two blind groove is orthogonal with the axis of this two logical groove, and logical groove, blind groove are uniformly distributed on the circumference of same footpath；There is a spring in bearing pin handle, before spring, have a packing ring.

By the logical groove on the pin prominent be aligned buttonhole on bearing pin during lifting, through buttonhole, pushpin footstalk, then bearing pin is ratated 90 degrees, release pins footstalk, spring makes pin dash forward in the blind groove being close on buttonhole.

During unloading, pushpin footstalk simultaneously rotates 90 degree, makes pin dash forward to deviate from from blind groove and be directed at logical groove, unloads lower bearing pin.

The invention has the beneficial effects as follows：Handling bearing pin, without rib-loop, only needs pushpin footstalk and ratates 90 degrees, moment completes；And, bearing pin the either end of two buttonholes can insert from button, time saving and energy saving, improves the utilization rate of hoisting machinery.

Brief description

Fig. 1 is the structural representation of the present invention；

Fig. 2 is the C of Fig. 1 to enlarged drawing.

Specific embodiment

The invention will be further described with specific embodiment below in conjunction with the accompanying drawings：

Fig. 1, Fig. 2 are embodiments of the invention, there is round tube hole on button 1 lower end buttonhole 6, symmetrical a pair is had on round tube hole lead to groove 3 and be located at and a pair blind groove 7 on this perpendicular bisector to logical groove 3 axis, this is evenly distributed on the circumference of same footpath to logical groove 3, blind groove 7；Bearing pin 2 head has a pair symmetrical pin to dash forward 8, and bearing pin 2 and pin are dashed forward 8 round tube hole and the logical grooves 3 passing through buttonhole 6, then pushpin footstalk 5 ratating 90 degrees, releases pin footstalk 5, and spring 4 makes pin dash forward 8 to be close to blind groove 7；During unloading, pushpin footstalk 5 simultaneously ratates 90 degrees, and so that pin prominent 8 is deviate from from blind groove 7, unloads lower bearing pin 2.

Claims

1. a kind of shackle, is made up of button, buttonhole, bearing pin etc., it is characterized in that having a pair of pin to dash forward on bearing pin, bearing pin shank has a spring, and buttonhole has A pair logical groove and a pair blind groove and a round tube hole.

2. it is characterised in that two described pins are prominent symmetrical, the prominent cross section of described pin is rectangle, described button for shackle according to claim 1 Described on eye, this is orthogonal to blind groove axis with this to the axis of logical groove, and this logical groove, blind groove uniformly divide on the circumference of same footpath Cloth.
