Specific embodiment
The invention will now be further described with reference to specific embodiments, the advantages and features of the present invention will be with description and
It is apparent.But examples are merely exemplary for these, and it is not intended to limit the scope of the present invention in any way.Those skilled in the art
Member it should be understood that without departing from the spirit and scope of the invention can details to technical solution of the present invention and form into
Row modifications or substitutions, but these modifications and replacement are fallen within the protection scope of the present invention.
Referring to Fig. 1 to Fig. 7, the present invention relates to a kind of ROV friendly fast shackle trippers, including shackle main body 1, master
Pin shaft 5, spring 6, fixed lateral pin 2 and limit bolt 3, the shackle main body 1 are arranged in headset shape, one end of the main pin 5
Be inserted into a fixed lateral pin 2 afterwards across two ears (the first ear 11 and the second ear 12) of shackle main body 1, the fixation lateral pin 2 with
Main pin 5 is vertically arranged, and the limit bolt 3 is arranged along the axial direction of main pin, and the limit bolt 3 is by main pin 5 and fixes
Lateral pin 2 links together；Described 6 sets of spring are on the axis 52 of main pin 5, one end of the spring 6 and the head 51 of main pin
Weld together, the other end is located at the outside of the first ear 11 of shackle main body, and moves cooperation with first ear 11.
Square hole 53 is offered on the axis 52 of the main pin, the fixation lateral pin 2 is adapted to square hole 53, sliding
Be mounted in square hole 53, the both ends of the fixation lateral pin 2 are located at the outside of square hole；Master in one end close to square hole 53
It is provided with two pieces of baffles being parallel to each other 4 on the axis of pin shaft, forms the space for accommodating limit bolt 3 between two block baffles 4.
It is provided with limit pin jack on the axis 53 of the main pin, is provided with spacer pin big hole 21 on fixed lateral pin 2
With spacer pin small sircle hole 22, the limit bolt 3 sequentially passes through limit pin jack, spacer pin big hole 21 and spacer pin roundlet
Behind hole 22, it is plugged in together with the fixed lateral pin.
Circular magnet is inlaid in the limit pin jack, on the fixation lateral pin outside the spacer pin small sircle hole
