FIG. 2 is a top view of the quick release check shackle.

Wherein, the curved ring 1, the transverse pin 2, the self-locking nut 3, the wrenching sleeve 4 and the rail part 5.

Detailed Description

Referring to fig. 1 to 2, the present invention is explained as follows:

as shown in fig. 1, a quick-release withdrawal stopping shackle is provided, which comprises a curved ring 1, wherein a transverse pin 2 is arranged in the curved ring in a penetrating and assembling manner, the head part of the transverse pin is provided with a threaded section, and the tail part of the transverse pin is an optical axis;

the first locking mechanism is as follows: the screw thread section of horizontal pin is joined in marriage in the screw hole of reserving on the first looper handle 3a1 of looper, the afterbody of horizontal pin passes looper second looper handle 3a2 and outwards extends, is located between first looper and the second looper handle the self-locking nut is joined in marriage on the screw thread section, and the head end of horizontal pin is equipped with the hand-operated handle, and self-locking nut 3 and hand-operated handle set up respectively and press from both sides tight first looper in the both sides of first looper, and the self-locking nut can the auto-lock when the atress like this.

The second locking mechanism is as follows: a transverse shaft vertically penetrates through the second curved ring, a pulling sleeve 4 which surrounds along the periphery of a handle of the second curved ring is assembled on the transverse shaft, a concave-shaped blocking rod part 5 which is used for limiting the transverse pin is formed at the bottom of the pulling sleeve, a concave bayonet is formed at the extending part of the tail part of the transverse pin, which corresponds to the blocking rod part, which penetrates through the handle of the second curved ring, the blocking rod part is just matched in the bayonet, the blocking rod part is positioned at the outer side of the handle of the second curved ring, a gap is reserved between the top edge of the blocking rod part and the bayonet surface, the inner shape of the blocking rod part is a wedge shape which is gradually thinned and becomes a slope surface beyond the second curved ring handle, a torsion spring which is used for providing rotary force for the pulling sleeve is arranged between the pulling sleeve and the second curved ring handle, the torsion spring is limited between the pulling sleeve and the second curved ring handle through small bulges respectively positioned on the pulling sleeve and the second curved ring handle, and the position of the wedge-shaped high point of the blocking rod, after the self-locking nut fails, the cross pin is limited at the outer side of the second bent ring handle by the rail part, and a second defense line is formed.

The third locking mechanism is as follows: the wedge-shaped high point of the blocking rod part is higher than the bottom edge of the second bent ring handle and the socket of the transverse pin, the wedge-shaped low point of the blocking rod part is lower than the bottom edge of the second bent ring handle and the socket of the transverse pin, the height difference is beta, the wedge-shaped high point is inserted into the bayonet, and the wedge-shaped low point is located outside the bayonet.

In order to ensure the integral rigidity of the component, the corner of the outer wall of the curved ring is a right-angle corner, the corner of the inner wall of the curved ring is an arc-shaped corner, and the tail end of the transverse pin is a tip end.

In the using process: penetrate first curved ring handle with the horizontal pin, with the locking nut assembly in the screw thread section, will pull the cover and fall down, penetrate the horizontal pin and pass the opening that second curved ring handle had, then loosen and pull the cover, pull the automatic card of cover and go into the bayonet socket.
