Detailed Description

The utility model will be further described with reference to the following figures and specific examples, but the scope of the utility model is not limited thereto.

As shown in fig. 1, the semi-automatic pin-releasing shackle device of the present invention includes a fixed cylinder 1, a spring 2, a shackle body 3, and a pin 4. The pin shaft 4 is of a cylindrical structure with a smooth surface, and a hollow cylindrical handle 6 is vertically welded at one end of the pin shaft 4, so that a constructor can conveniently pull the pin shaft 4; the pull rope is connected to the hollow cylindrical handle 6, and the other end of the pull rope is connected with the pull ring, so that a constructor can pull the pin shaft 4 by using the pull ring without climbing to a higher position, construction safety is guaranteed, and potential safety hazards are reduced; the length of the pull rope is selected according to actual construction requirements.

As shown in fig. 1 and 2, a snap ring 7 is welded on the outer surface of a pin shaft 4 near a handle 6, a spring 2 is installed on the pin shaft 4 between the snap ring 7 and the handle 6, the diameter of the snap ring 7 is larger than the diameter of the cross section of the spring 2, and the snap ring 7 can fix the spring 2 on the pin shaft 4.

As shown in fig. 1, the shackle body 3 is preferably of an arch structure, two pin holes 5 for the pin 4 to pass through are symmetrically arranged at two ends of the shackle body 3, the two pin holes 5 are the same in size, and the diameter of the pin hole 5 is matched with the size of the pin 4.

As shown in fig. 1 and 3, the fixed cylinder 1 is a hollow cylindrical structure, the two ends of the fixed cylinder 1 are both provided with a fixed plate 8, the center of the fixed plate 8 is provided with a through hole, and the diameter of the through hole is matched with the size of the pin shaft 4; the fixed cylinder 1 is fixedly arranged on the pin shaft 4, the clamping ring 7 and the spring 2 are both positioned in the fixed cylinder 1, one end of the fixed cylinder 1, far away from the handle 6, is welded with the end of one end of the shackle body 3, the center of the fixed cylinder 1 is ensured to be consistent with the center of the pin hole 5, and the pin shaft 4 can conveniently penetrate through holes in the centers of the pin hole 5 and the fixed plate 8.
