The specific embodiment

See also Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the rapid unhooking device that the utility model provides comprises:

Hook seat 10 is composed of a fixed connection by two seat boards that are parallel to each other 11;

Coupler body 20 is articulated in by bearing pin 21 between two seat boards 11 of this hook seat 10, and these coupler body 20 1 ends have a reclinate hook tongue 22, and the other end is a block 23; Side at block 23 also is provided with locating dowel pin 24, and this locating dowel pin 24, is rotated to this side to prevent coupler body 20 between two seat boards 11 by screw retention;

Spanner 30 is articulated in the outside of this hook seat 10 by rotating shaft 31, and this rotating shaft 31 is fixed on this spanner 30 by tightening screw 312, and this rotating shaft 31 is rotated synchronously with this spanner 30.And Fig. 5 A, Fig. 5 B, Fig. 5 C is the three-face view of this rotating shaft, 31 pairs of this rotating shafts should coupler body 20 the position of block 23 offer one and dodge groove 311, when pushing away on this spanner 30, the cylindrical outer surface of this rotating shaft 31 is connected to the block 23 of this coupler body 20, prevent that this coupler body 20 is along the right-hand revolution shown in Fig. 1 (as shown in Figure 1), when this spanner 30 falls, the groove 311 of dodging of this rotating shaft 31 can pass through for the block 23 of this coupler body 20, this coupler body 20 can make hook tongue 22 and boat fall (not giving diagram) break away from the relation of extension of colluding along the right-hand revolution shown in Fig. 1.Can also see that from Fig. 1, Fig. 2 this spanner 30 also has a rib 33, spanner 30 is limited to push position for following master cock 40; And, this rotating shaft 31 is positioned at the location on the lower side (as shown in Figure 1) of the barycenter 34 of this spanner 30, thereby after following master cock 40 qualifications of releasing to the rib 33 of spanner, this spanner 30 makes rotating shaft 31 can initiatively break away from the block 23 of this coupler body 20 of butt by gravity;

Master cock 40, comprise fixed muffle 41, slide shaft 42, retracing spring 43 and operating handle 44, these fixed muffle 41 1 ends are the bodys 411 that pass two seat boards 11 of this hook seat 10, fixed muffle 41 other ends are the shoulders 412 that are fixed on this hook seat 10, and this shoulder 412 has a centre hole; These slide shaft 42 end wises comprise the interference section 421 that diameter reduces successively, interlude 422 and control section 423, the described retracing spring 43 of interlude 422 upper sleeve throughs at this slide shaft 42, control section 423 with this slide shaft 42 penetrates the centre hole of shoulder 412 in the body 411 of this fixed muffle 41 then, the diameter of the interference section 421 of this slide shaft 42 equals or is slightly less than body 411 diameters, make it can telescopic moving in body 411, and the two ends of this retracing spring 43 of interlude 422 upper sleeve throughs of slide shaft 42 are respectively against the shoulder 412 of fixed muffle 41 and the interference section 421 of slide shaft 42, the interference section 421 that makes slide shaft 42 is overhanging under normal conditions and block the rib 33 of this spanner 30, after the control section 423 of this slide shaft 42 passes the centre hole of shoulder 412 of this fixed muffle 41, link to each other with described operating handle 44, control the flexible state of interfering section 421 by this operating handle 44; This operating handle 44 articulates by a pin 441 mutually with the control section 423 of this slide shaft 42 in the present embodiment, and this operating handle 44 have one with the shoulder 412 contacted camming surfaces 442 of this fixed muffle 41 (this camming surface 442 also can be directly and these hook seat 10 contacted faces), point on this camming surface 442 and the distance between this pin 441 become gradually greatly and (perhaps diminish), when rotating this operating handle 44, reason owing to camming surface 442, distance between this pin 441 and the shoulder 412 can become big gradually or diminish, corresponding the changing of flexible state of this slide shaft 42, slide shaft 42 interference sections 421 will be blocked the rib 33 of this spanner 30 or disengage with this rib 33;

Protection spring 50, winding is on this fixed muffle 41, one end is fixed, the hook tongue 22 of the other end and this coupler body 20 connects, side at this protection spring 50 and an end of hook tongue 22 butts also is provided with another locating dowel pin 51, this another locating dowel pin 24 also is to be screwed between two seat boards 11, outwards ejects to prevent this protection spring 50; The effect of this protection spring 50 has two: one, the elastic-restoring force of this protection spring 50 can prevent this coupler body 20 along the anticlockwise motion shown in Fig. 1, makes the block 23 of unhook keep closed contact with the outer peripheral face of rotating shaft 31; , initiatively do not oppressing under the situation of this protection spring 50 with hook tongue 22 fits of coupler body 20 in case the lifting part of two canoes (being generally ring body) is oppressed this protection spring 50, just can not get loose, thereby prevent unexpected generation with the hook tongue 22 of coupler body 20.

Above-mentioned parts (comprising hook seat 10, coupler body 20, spanner 30, master cock 40 and protection spring 50) all are material with the corrosion-resistant steel, to prolong its service life.

Next introduce working process of the present utility model:

As shown in Figure 1, tightening state corresponding to the rapid unhooking device, at first, operating handle 44 is opened, and the interference section 421 of slide shaft 42 is retracted in the fixed muffle 41, then, spanner 30 pushes away under external force, connect until the outer peripheral face of rotating shaft 31 and the block 23 of coupler body 20, then rotate this operating handle 44, make the interference section 421 of slide shaft 42 stretch out and block the rib 33 of spanner 30.Thus, spanner 30 can't rotate, and the hook tongue 22 of unhook is remained on collude to hang the position.If add the booster action of protection spring 50, can prevent that more the accident of locking hook takes place.

And as shown in Figure 2, when needs canoe and this rapid unhooking are separated, only need open this operating handle 44, the interference section 421 of slide shaft 42 is retracted in the fixed muffle 41, spanner 30 rotates by gravity, what make rotating shaft 31 dodges groove 311 up, then the block 23 of coupler body 20 will be dodged the groove 311 from this and be passed through, under the canoe tension, and coupler body 20 right-hand revolutions (as shown in Figure 2), canoe slippage from hook tongue 22, thus the relation of extension of colluding removed.

As shown in the above, the utility model can be guaranteed to collude extension safety when colluding extension, and when need get loose, operation is simple and reliable, except being applied to also can be applied to fields such as building engineering, mechanical engineering in the marine lifting operation.

More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.
