Abstract
A lifting hook comprises a ring (1) and a lifting hook main body (2) which are hinged with each other; compared with the prior art, because the ring and the lifting hook main body are hinged with each other, when an object is lifted to move, the ring and the lifting hook main body form a certain angel under the action of the weight of the lifting object, but the lifting hook main body and the object are kept to move consistently, so the object on the lifting hook main body cannot slide to the opening of the lifting hook main body to fall off, and thereby the lifting object cannot easily be broken and hurt workers below due to the falling off thereof; and meanwhile, the stress direction of the hinge part is the design stress direction of a hinge shaft, so the hinge shaft is not easy to be broken, and better reliability is obtained.
Description
Technical field:
The utility model relates to a kind of suspension hook.
Background technology:
At present, the suspension ring of market hook are all captiveed joint with the suspension hook body, when suspension hook plays object of which movement, because the article of lifting all have certain weight, so certain inertia is arranged during motion, suspension ring and suspension hook hook body will integral inclinations, and like this on the suspension hook body article in very easily landing from the suspension hook body under the influence of self gravitation, the junction of suspension ring and suspension hook body is being born the power along sense of motion at this moment simultaneously, this shearing force very easily makes the junction of suspension ring and suspension hook body lose efficacy and rupture, so safety is relatively poor, the article of feasible lifting drop easily and damage and break, also pound the staff of below easily, cause unnecessary personal safety accident.
The utility model content:
The utility model provides a kind of hoisting object to be difficult for dropping when moving at above problem, and difficult inefficacy in the junction of suspension ring and suspension hook body and then safety be suspension hook preferably.
The utility model overcomes the above problems used technical scheme: a kind of hook with following structure is provided, and it comprises suspension ring and suspension hook body, and described suspension ring and hanger bulk are hinged.
Described pivotally attached concrete structure is: described suspension ring are for falling " U " font, and two free ends of " U " font are equipped with hinge hole, the upper end of described suspension hook body is fixed with hinge, the axis of described hinge and suspension hook body are rectangular, simultaneously the two ends of hinge are in the suspension hook body outside, the hinge hole on the described suspension ring all with the suspension hook body on hinge be rotationally connected.
After adopting above structure, compared with prior art, the utility model is owing to suspension ring and suspension hook body pivotally attached, when then lifting object of which movement, under the effect of hoisting object weight, suspension ring and suspension hook body are certain angle, and the motion that is consistent of suspension hook hook body and object, the object on the suspension hook body is with regard to the opening part that can not slide into the suspension hook body and landing like this, just do not have the article landing of lifting yet after, break easily, also pound staff's problem of below easily; Simultaneously the direction of the power of bearing of hinged place is exactly the direction of the jointed shaft design power of being born, so that jointed shaft is difficult for is destroyed, reliability is better.So the utility model hoisting object is difficult for landing when motion and safety is better.
As improvement, described suspension hook body is provided with closing device, and then closing device makes that the article that lift on the suspension hook body can be from the opening part landing of suspension hook body, so safety of the present utility model is better.
As further improvement, described closing device comprises buckle that is located on the suspension hook body and the dead bolt that can outwards open, the free end of described suspension hook body openings place one end is provided with groove, described buckle is positioned at groove, and the buckle middle part is hinged in the groove, the lower surface of described buckle left end close end is provided with projection, the right-hand member of buckle is near the right-hand member of groove, the free end of one end of described dead bolt and the suspension hook body openings place other end is hinged, and the other end of dead bolt is provided with the depression that interlocks with buckle left end lower surface projection; Described suspension hook body is the concave shape structure, and the opening of suspension hook body in the horizontal direction, described suspension hook body is provided with the right-hand member of the buckle stop gear to upper limit, be provided with Bringing-back mechanism between the inwall of described buckle left end and groove, be provided with in the described groove and be used for the spacing limited post of dead bolt other end turning clockwise; Because dead bolt is outwards opened, the angle of then opening is bigger, can will be hooked on the suspension ring body with similar big rope or the shackle of the opening of suspension hook body, other of prior art has the suspension ring body of dead bolt then can't be accomplished, makes that range of use of the present utility model is wider.
As further improving again, described Bringing-back mechanism comprises ring bolt and spring, described ring bolt is fixed on the inwall of groove, one end of described spring is connected with the left end of buckle, and the other end of spring is connected with the ring of ring bolt, and then the structure of Bringing-back mechanism is simpler, so maintenance time is shorter, life-span is longer, thereby makes that the utility model is easy to safeguard that stability in use is higher.
As further improving again, described stop gear is a positioning plate, one end of described positioning plate is fixed on the suspension hook body, the other end in groove the buckle right-hand member above, then stop gear has only used positioning plate, so structure is simpler, occupation space is also just less, be easy to safeguard, and increased the stability of using.
As further improving, the upper surface near right-hand member on the described buckle is provided with projection, and then projection helps the user and is relatively easy to an end of buckle is pressed, and does not need to make that finger enters in the groove, so help opening of dead bolt.
