In order to achieve the above purpose, the utility model adopts the following technical scheme:

a hook device convenient for hoisting operation comprises a lifting lug, a baffle and a hook, wherein the baffle is fixed at the bottom of the lifting lug, the hook is movably arranged on the baffle, a stop block is fixedly arranged at the lower part of the baffle, a first spring is fixedly arranged at the root of the hook, and one end of the first spring is fixed on the stop block; the inner side surface of the hook is provided with a strip hole communicated with the spring groove; a second spring and a sliding block are arranged in the spring groove; the top end of the sliding block penetrates through the strip hole and extends outwards, and the sliding block is arranged in the spring groove in a sliding mode; one end of the second spring is fixed at the root of the hook, and the other end of the second spring is fixed on the sliding block.

Preferably, the cross-sectional shape of the spring slot is circular, and the width of the bar hole is smaller than the diameter of the cross-sectional circle of the spring slot.

Preferably, the slider is L-shaped, the bottom section of the slider is circular, the diameter of the bottom section of the slider is smaller than that of the spring groove section circle, and the diameter of the bottom section of the slider is larger than the width of the bar hole.

Preferably, the second spring is arranged in the spring groove along a sectional curve of the spring groove.

The utility model discloses a design can realize taking the automatic tripping of self-locking function's couple, can save a large amount of manpower consumptions, and convenient operation eliminates the potential safety hazard when artifical the dropout, ensures operation personnel's safety.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 to 3, a hook device convenient for lifting operation comprises a lifting lug 1, a baffle 8 and a hook 6, wherein the baffle 8 is fixed at the bottom of the lifting lug 1, the hook 6 is movably arranged on the baffle 8, a stop block 2 is fixedly arranged at the lower part of the baffle 8, a first spring 7 is fixedly arranged at the root part of the hook 6, one end of the first spring 7 is fixed on the stop block 2, the first spring 7 applies tension to the baffle 8, an opening of the hook 6 can be opened under the condition of no bearing, meanwhile, the hook 6 can be prevented from being closed with the stop block 2 by the tension of the first spring 7 to the baffle 8, a spring groove 9 is formed in the inner side surface of the hook 6, and the shape of the section curve of the spring groove 9 is the same as that of the section curve of the inner side surface of the hook 6 and is in the shape of an arc; the inner side surface of the hook 6 is provided with a strip hole 4 communicated with the spring groove 9; a second spring 5 and a sliding block 3 are arranged in the spring groove 9; the top end of the sliding block 3 penetrates through the strip hole 4 and extends outwards, and the sliding block 3 is arranged in the spring groove 9 in a sliding mode; one end of the second spring 5 is fixed at the root of the hook 6, the other end of the second spring is fixed on the sliding block 3, and the sliding block 3 is jacked to the tip of the hook 6 by the second spring 5 in a natural state.

Furthermore, the cross section of the spring groove 9 is circular, and the width of the strip hole 4 is smaller than the diameter of the cross section circle of the spring groove 9, so that the second spring 5 cannot be ejected from the strip hole 4 when moving in the spring groove 9.

Furthermore, the slider 3 is L-shaped, the bottom section is circular, the diameter of the bottom section is smaller than that of the section circle of the spring groove 9 and larger than the width of the strip hole 4, and the slider 3 can only slide along the spring groove 9 and cannot fall out of the spring groove 9 in the sliding process.

Further, the second spring 5 is arranged in the spring groove 9 along the section curve of the spring groove 9, so that the second spring 5 extends and contracts along the shape of the spring groove 9, and the smoothness of extension and contraction of the second spring 5 is ensured.

When the hook is used, under the condition of no load bearing, the first spring 7 pulls the baffle 8 to enable the hook 6 to rotate on the baffle 8 for a certain angle, so that the opening at the tip end of the hook 6 is opened, and the hook 6 can be conveniently hung with a hanging belt; when the hook 6 is hung with the hanging belt, the hanging belt enters the hook 6 from the opening of the tip end of the hook 6, the sliding block 3 is pressed to the root position of the hook 6 from the tip end of the hook 6 along the spring groove 9, and meanwhile, the second spring 5 is compressed; under the action of gravity, the hook 6 bears downward gravity to offset the tension of the first spring 7, so that the hook 6 is in a naturally drooping state, the hook 6 is closed and self-locked, and the tip end of the hook 6 is close to the stop block 2; after putting down the heavy object, first spring 7 exerts pulling force to dog 2, makes the opening of couple 6 reopen, and second spring 5 resumes simultaneously, drives slider 3 and slides to the most advanced position of couple 6, pushes out couple 6 with hanging the area, accomplishes the unhook.
