Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is done further detailed introduction.

Fig. 1 is the front view of universal quick connecting connector.

Fig. 2 is that half sectional view is looked on the left side of universal quick connecting connector.

The specific embodiment

From Fig. 1 and Fig. 2 as can be known, universal quick connecting connector mainly is made up of pendulous device, slewing reduction apparatus, quick-acting connector, oil cylinder 3.

Pendulous device wherein mainly is made up of symmetrical two side plates 4, junction plate 11, mount pad 13: symmetrical two side plate 4 upper ends all have two pin-and-holes, the middle bearing pin 12 that interts is respectively with the front end of excavator boom and the rod hinge connection of excavator; The junction plate 11 of the lower end of left side plate 4 and front and back symmetry is welded into general frame; The all fixedly connected mount pad 13 in the outside of left side plate 4, mount pad 13 adopts flange to fix with the cylinder end of oil cylinder 3.

Slewing reduction apparatus mainly is made up of with worm gear 9, U-shaped ear seat 5, otic placode 14 intermeshing worm screw 8 in hydraulic motor 2, casing 7, the casing 7: the left end of worm screw 8 is connected with hydraulic motor 2, and right-hand member matches with the side plate hole in the casing 7; The all symmetrical fixedly U-shaped ear seat 5 in the outside of casing 7 front-backs, hinged with the circular arc ear seat that inserts junction plate 11 wherein by gyroaxis 10; Casing 7 left and right sides symmetries are stretched out otic placode 14, and are hinged with the rod end earrings of oil cylinder 3 by bearing pin 15.

Quick-acting connector mainly is made up of pallet 6, former and later two symmetrical side plates 1: pallet 6 is connected by pressing plate 16 with worm gear 9, the centre of gyration of the centre of gyration of pallet 6 and worm gear 9 coincides, with end about the front and back side plate 1 of pallet 6 welding semicircle open slot is arranged all, be connected with the connecting pin of facility such as excavator bucket.
