Be below the technical scheme of further improvement of the utility model:
Preferably, described movable latch hook is contained on described side plate by hook pin and also can rotates relative to side plate, the rotation path of movable latch hook is provided with one can be contained in spacer pin on side plate with pulling and pushing, when spacer pin inserts, the second arm lock is combined in second group of open card of link by movable latch hook.
The return flexible member that a driving activity latch hook and the second arm pin keep in touch described side plate is equipped with.Further, described return flexible member is return spring or blob of viscose or nylon rod.
Preferably, described two groups of open card are semicircular arc card.
Described semicircular arc card inwall is equipped with strengthens arc plate.
Described return flexible member replaces with hydraulic jack.
The opening direction of described first group of open card and the opening direction near normal of second group of open card, near normal described in the utility model refers in engineering reality, both absolute upright can not be ensured, the angle that always deviation is certain, as long as but can ensure that open card conveniently snaps in two arm pins.
Described return spring is carbon spring steel wire.
The described parts that changed are bucket or the excavator such as ridge buster or quartering hammer front end equipment.
Above structure, fixing port mechanical type hydraulic quick coupler of the present utility model eliminates the original screw rod latch hook mechanism of old money fixing port mechanical type hydraulic quick coupler, locks the arms pin of bucket or ridge buster or quartering hammer with a movable latch hook.Its advantage is: 1, technique simplifies, and movable latch hook is more strengthened than original screw locking mechanism rigidity and safety.2, simple operation, quick replacement device is more less than original hydraulic quick coupler time, more laborsaving.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple and reasonable, steel work intensity strengthen, duty time more safe and reliable, it is more convenient, time saving and energy saving to operate.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
