Figure 12 discloses a kind of goat's horn Slip Hook, and chain is connected with goat's horn Slip Hook by the bearing pin being arranged in goat's horn portion.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of chain and shrinks adjustment hoisting rig, it provides the connection mode of a kind of novel chain and hook.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of chain shrinks and regulates hoisting rig, comprise the neck of hook of the hook body fork-shaped square with being positioned at hook with it, the relative inner portion of two yokes of the neck of hook is equipped with the chain hanging groove tilting upward extension, backing pin is across on two yokes and backing pin can move along own axes direction, backing pin has breach, backing pin is positioned at below chain hanging groove, the definition chain link entered in chain hanging groove is the first chain link, chain link adjacent above first chain link is the second chain link, it is primary importance that backing pin is in the breach position exposed to completely between two yokes, backing pin be in primary importance could meet the first chain link to enter in chain hanging groove and the second chain link from breach by moving.
Above-mentioned chain shrinks and regulates hoisting rig, two yokes all have the pin-and-hole holding described backing pin, define two yokes and be respectively left yoke and right yoke, pin-and-hole on left yoke is the blind hole of opening towards right yoke, pin-and-hole on right yoke is the through hole that thickness direction runs through right yoke, arrange stage clip between at the bottom of backing pin and hole, right yoke is arranged and determines that backing pin moves the locating dowel pin of right stop, locating dowel pin is vertical with backing pin to be arranged.
Above-mentioned chain shrinks and regulates hoisting rig, and backing pin is provided with the groove that left and right directions extends, and locating dowel pin is arranged in groove, and groove left side wall touches the right stop that locating dowel pin is backing pin, and groove right side wall touches the left stop that locating dowel pin is backing pin.
Above-mentioned chain shrinks and regulates hoisting rig, and the right yoke lateral surface be positioned at above and below through hole is provided with lug boss.
Above-mentioned chain shrinks and regulates hoisting rig, and breach is arc notch.
Above-mentioned chain shrinks and regulates hoisting rig, and one end of stage clip is positioned at spring base hole, and spring base hole is the blind hole being opened in backing pin one end.
Backing pin has breach, backing pin is positioned at below chain hanging groove, and when chain is connected with the neck of hook, backing pin is in primary importance, namely backing pin is in breach and exposes to position between two yokes completely, first chain link enters in chain hanging groove, and the second chain link is from breach by moving, and then backing pin moves to other position, under the stop of backing pin, second chain link can not be crossed backing pin and move down, and the first chain link can not be deviate from chain hanging groove, ensure that fixing and the safety of connection.When chain and the neck of hook remove be connected namely throw off time, backing pin is in primary importance, and the second chain link is from breach by moving down, and the first chain link shifts out in chain hanging groove, can complete remove connect.Different chain links is positioned at chain hanging groove, can realize the adjustment of chain length.

Detailed description of the invention
As shown in Figure 1 to 11, a kind of chain shrinks and regulates hoisting rig, comprise the neck of hook of hook body 1 fork-shaped square with being positioned at hook with it, the relative inner portion of two yokes 8 of the neck of hook is equipped with the chain hanging groove 7 tilting upward extension, backing pin 3 is across on two yokes and backing pin can move along own axes direction, backing pin has breach 10, backing pin is positioned at below chain hanging groove.The definition chain link entered in chain hanging groove is the first chain link 13, chain link adjacent above first chain link is the second chain link 14, it is primary importance (as shown in Figure 1) that backing pin is in the breach position exposed to completely between two yokes, backing pin be in primary importance could meet the first chain link to enter in chain hanging groove and the second chain link from breach by moving.
Two yokes all have the pin-and-hole holding described backing pin, define two yokes and be respectively left yoke and right yoke, pin-and-hole on left yoke is the blind hole of opening towards right yoke, pin-and-hole on right yoke is the through hole that thickness direction runs through right yoke, between at the bottom of backing pin and hole, stage clip 11 is set, right yoke is arranged and determines that backing pin moves the locating dowel pin 2 of right stop, locating dowel pin is vertical with backing pin to be arranged.
Backing pin is provided with the groove 12 that left and right directions extends, and locating dowel pin is arranged in groove, and groove left side wall touches the right stop that locating dowel pin is backing pin, and groove right side wall touches the left stop that locating dowel pin is backing pin.
The right yoke lateral surface be positioned at above and below through hole is provided with lug boss 4, and form space 5 between lug boss, this ergonomic designs can prevent overhanging backing pin from being injured by a crashing object.
