Abstract

A hook with a dropping prevention mechanism comprises a hook body consisting of a hook handle and a hook ring which are connected, wherein a pin shaft penetrates through the joint of the hook handle and the hook ring, and is connected with a tongue plate and a pulling component which is fixedly connected with the tongue plate. The hook has simple structure and convenient operation, and the pulling component can drive the tongue plate to rotate and displace by using the pins shaft as the axes only through slightly pulling the puling component, thereby realizing the enter and exit of a steel wire rope, a chain, a hoisting belt, a spreader and the like, and protecting the connection. The hook has low risk and high efficiency, improves the speed and quality of hoisting, avoids using a torsion spring, and further guarantees the personal safety.

Description

Suspension hook with anti-shedding mechanism

Technical field

The utility model relates to and is used for transmitting hoisting force to the object, be attached to crane lifting, fall or trailer coupling on or be used for hanging element or device with these mechanism's bonded assembly load, specifically, relate to a kind of suspension hook that prevents that load unintentionally from coming off that has.

Background technology

Promote, fall or draw gear on hang element with load usually, be used to hang, drawbar load, for example, the suspension hook on the hoisting crane etc.If these are hung element the anti-shedding mechanism that matches is not set, so in the course of the work, the connecting portion of connection load or rope etc. just might not only cause device damage from hanging landing on the element, also may cause the generation of personnel casualty accidents.

In order to prevent that load from coming off from suspension hook, present way is that elastic tongue piece is set on suspension hook, and promptly tongue piece installs torsion spring additional, and the dependence torsion spring resets tongue piece and fixes.For example the anti-slip mechanism of the disclosed a kind of crane hook of Chinese patent publication number CN201172576 at bearing pin of the inboard riveted joint of the bar portion of mechanism, is equipped with torsion spring on the bearing pin, and an end of torsion spring leans against the bar portion inboard of suspension hook, and the other end leans against the tongue piece inboard.Under the effect of torsion spring, the end of tongue piece is against the inboard of suspension hook bill.When the rope of crane hook overcomes the torsion of torsion spring, enter suspension hook when inner, tongue piece is under the effect of torsion spring, and its end is against the inboard of suspension hook structure point, makes that rope is unlikely to come off in suspension hook, has played the safety precaution effect.

But this elastic tongue piece that generally uses also exposes some problems in practice gradually at present, mainly is to fall short of service life, and after use after a while, torsion spring is damaged than being easier in operation repeatedly, needs to change.Also can there be certain security risk, for example in the production use in workshop,, will collapses owing to the elastic force of self and be mapped to any direction, may wound on-the-spot staff like this if torsion spring breaks away from and collapses out from suspension hook suddenly.

The utility model content

The technical problems to be solved in the utility model provides a kind of simple in structure, and is both easy to operate, the safe and reliable again suspension hook with anti-shedding mechanism.

In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:

A kind of suspension hook with anti-shedding mechanism comprises the suspension hook body that is connected and composed by the neck of hook and shackle, and the joint cross-under of the described neck of hook and described shackle has bearing pin, described bearing pin be connected with tongue piece and with tongue piece affixed stir parts.

The end of described tongue piece is resisted against the structure point inboard of described suspension hook body.

The beneficial effects of the utility model are:

Anti-shedding mechanism of the present utility model is simple in structure; easy to operate, only need stir parts outward gently, stirring parts, will to drive tongue piece be that the axle center is rotated and is shifted with the bearing pin; so not only realize the turnover of steel rope, chain, hanging belt, suspender etc., and play connecting the effect of protection.Therefore risk of the present utility model is low, and efficient is high again, has improved handling speed and quality, also avoids the use to torsion spring, has guaranteed personal safety better.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a use scheme drawing of the present utility model.

Among the figure: the neck of hook---11, shackle---12, bill---13,

Bearing pin---2, tongue piece---3, stir parts---4.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

As shown in Figure 1, the utility model provides a kind of suspension hook with anti-shedding mechanism, comprise the suspension hook body that connects and composes by the neck of hook 11 and shackle 12, the described neck of hook 11 has bearing pin 2 with the joint cross-under of described shackle 12, described bearing pin 2 is connected with tongue piece 3, and the end of described tongue piece 3 is resisted against bill 13 inboards of described suspension hook body.Described tongue piece 3 can be made by steel plate or round steel.Described tongue piece 3 is connected with by bearing pin 2 and stirs parts 4.

As shown in fig. 1, tongue piece in the present embodiment 3 is made into arc by sheet steel, stirs parts 4 and is made by round steel, under non-working condition, stirs parts 4 and takes and be against shackle 12 outsides.Described concrete shape of stirring parts 4 can also have multiple variation, as long as be convenient to hand-held stirring.

During use, as shown in Figure 2, only need stir parts 4 outward gently, stirring parts 4, will to drive tongue piece 3 be that the axle center is rotated and is shifted with bearing pin 2, realizes the turnover of steel rope, chain, hanging belt, suspender etc. like this, and play the effect of protecting connecting.

Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the present utility model.

Claims

1. the suspension hook with anti-shedding mechanism comprises the suspension hook body that is connected and composed by the neck of hook and shackle, it is characterized in that, the joint cross-under of the described neck of hook and described shackle has bearing pin, described bearing pin be connected with tongue piece and with tongue piece affixed stir parts.

2. the suspension hook with anti-shedding mechanism according to claim 1 is characterized in that, the end of described tongue piece is resisted against the structure point inboard of described suspension hook body.
