Abstract

The utility model discloses an unloading fastener, aim at providing one kind without the rib knitting just can be quick conveniently with pivort fixation in order to lift by crane on the button hole, maybe will sell the axle and extract the unloading fastener of button hole in order to unload. Its structure is: round pin spindle nose portion has a canceling suddenly on the outer face of cylinder, the logical recess that has a flexible hole and a pair of symmetry to distribute on the button hole, and a canceling of selling spool on and is suddenly passed flexible hole and logical recess, then will sell the rotation of axes 90 degrees, the round pin spring messenger in another blind recess to the symmetric distribution, in the round pin footstalk portion on the button hole that advances by leaps and bounds blind recess is suddenly hugged closely to the round pin, and pivort fixation is on the button hole in the locking, during the discharge, pressing round pin footstalk portion, making the round pin suddenly leave blind recess, rotatory round pin axle is 90 degrees again, and the round pin axle just can be worn out flexible hole and logical recess withdraw from the button hole. The utility model is suitable for a lift by crane the hoist.

Description

Shackle

Technical field

The utility model relates to a kind of rising and reuses part, especially relates to hoisting sling.

Background technology

Existing lifting shackle, be made up of button, buttonhole, bearing pin etc., buttonhole and button have rib-loop to be connected, lifting article, by bearing pin through buttonhole, outer for head rib-loop need be screwed into rib-loop in buttonhole; Bearing pin need be turned on rib-loop when unloading thing, waste time and energy, reduce the degree of utilization of elevator machinery.

Utility model content

The utility model overcomes the above-mentioned deficiency of prior art, provides a kind of fast easy and simple to handle, without the shackle that bearing pin and buttonhole just can be fixed or they be separated by rib-loop.

The utility model adopts following technical scheme: a kind of shackle, is made up of button, bearing pin, buttonhole, spring etc.Bearing pin head external cylindrical surface has symmetrical pair of pin dash forward, its cross-sectional plane is rectangle; On buttonhole, the pin of relative bearing pin head is dashed forward on position a pair logical groove, and at this to the midperpendicalar of logical groove line there being a pair symmetrical blind groove, this two blind groove, two logical grooves are circumferentially uniformly distributed in same footpath; A spring is had in bearing pin handle.

Dashed forward by pin on bearing pin during lifting the logical groove aimed on buttonhole, through buttonhole, pushpin footstalk, then by bearing pin 90-degree rotation, release pins footstalk, spring makes pin dash forward to be close in the blind groove on buttonhole.

During unloading, pushpin footstalk also rotates 90 degree, pin is dashed forward and deviates from from blind groove and aim at logical groove, unload lower bearing pin.

The beneficial effects of the utility model are: handling bearing pin, without rib-loop, only needs pushpin footstalk and 90-degree rotation, completes instantaneously, time saving and energy saving, improves the degree of utilization of elevator machinery.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

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

Detailed description of the invention

Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described:

Fig. 1, Fig. 2 are embodiments of the present utility model, button 1 lower end buttonhole 6 there is round tube hole, round tube hole have a pair symmetrical logical groove 3 and be positioned at this to a pair blind groove 7 on the midperpendicalar of logical groove 3 axis, this is evenly distributed on same footpath circumferentially to logical groove, blind groove; Bearing pin 2 head has a pair symmetrical pin prominent 8, and bearing pin 2 and pin dash forward 8 through the round tube hole of buttonhole and logical groove 3, then pushpin footstalk 5 90-degree rotation, releases pin footstalk 5, and spring 4 makes pin prominent 8 be close to blind groove 7; During unloading, pushpin footstalk 5 is 90-degree rotation also, pin prominent 8 is deviate from from blind groove 7, unloads lower bearing pin 2.

Claims

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

2. shackle according to claim 1, it is characterized in that two described pins are prominent symmetrical, described pin cross-sectional plane of dashing forward is rectangle, on described buttonhole described this to the axis of logical groove and this is orthogonal to blind groove axis, this logical groove, blind groove are circumferentially uniformly distributed in same footpath.
