Description

The self-locking type suspension hook

Technical field

The utility model relates to a kind of suspension hook, is specifically related to a kind of self-locking type suspension hook.

Background technology

At present, the self-locking type suspension hook of lifting machinery and equipment is all the integral type structure, mainly there is following defective in the self-locking type suspension hook of this integral structure: the one, because opening degree is less, be subjected to the impact of the factors such as space or position, when installing in the suspension ring on the machinery and equipment or the hole of hanger, relatively waste time and energy; The 2nd, in order to prevent that hanging thing breaks off relations, the article such as needs use iron wire are with the closure of openings of suspension ring.Above-mentioned two defectives have been brought and have been used inconvenience, ineffective adverse consequences.

The utility model content

The technical problems to be solved in the utility model is for defects, and a kind of convenient to use and self-locking type suspension hook that can increase work efficiency is provided.

In order to solve the problems of the technologies described above, the utility model provides a kind of self-locking type suspension hook of following structure, its constructional feature is to comprise hangs box, hang and be connected with lifting rope on box top and install ring, hang to be provided with in box by hinge and be hinged on lock box on its two side, be set with torsion spring on hinge, an end of torsion spring contacts with the inner roof wall that hangs box, and the other end of torsion spring contacts with lock box; Hang on the box bottom surface and be connected with the main hook body, be hinged with the auxiliary hook body on the main hook body; Hang box and enter away from the free end that an end of main hook body is provided with for the auxiliary hook body side opening that hangs in box, the free end of auxiliary hook body is provided with free end when the auxiliary hook body and enters the dead bolt that can insert after hanging in box in lock box and be locked by lock box.

Described lock box comprises the lock box body, the lock box body one end sealing other end opens wide, the end face of lock box body closed end is the dip plane, the dip plane is provided with the dead bolt insert port, the diapire of lock box body and two side are from its open end formation open slot that stretches out, and the two side of open slot is provided with the hinge axis hole that installs for hinge.

Be equipped with the instrument jack that the lock box bottom surface is exposed on described relative two sides of hanging box.

The utility model links together because its main hook body and auxiliary hook body adopt hinged mode, and namely both non-pin jointed end can be relatively movable, and therefore, the opening angle of main hook body and auxiliary hook can change arbitrarily.During use, can conveniently the auxiliary hook body be penetrated in the hole of suspension ring or hanger.After the auxiliary hook body penetrates in the hole of suspension ring or hanger, upset auxiliary hook body enters its free end and hangs in box, dead bolt on auxiliary hook body free end is contacted with the dip plane of lock box body, continue upset auxiliary hook body, dead bolt just orders about and turns on the lock box body until dead bolt enters the dead bolt insert port, and remove the auxiliary hook body application of force this moment, and the lock box body resets under the effect of torsion spring, the end wall of the lock box body of dead bolt insert port top can hook dead bolt, thereby realizes self-locking.

In sum, the utility model has the advantage of: simple in structure, use efficient and conveniently, have auto-lock function.

Description of drawings

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:

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

Fig. 2 is the structural representation of lock box shown in Fig. 1;

Fig. 3 is the birds-eye view of Fig. 2.

The specific embodiment

As shown in Figure 1, the self-locking type suspension hook comprises and hangs box 1, hangs to be connected with lifting rope on box 1 end face and to install ring 2, hangs on box 1 bottom surface and is connected with main hook body 6, is hinged with auxiliary hook body 7 on main hook body 6; Hanging box 1 is that non-pin jointed end enters the side opening 9 that hangs in box 1 away from the free end that an end of main hook body 6 is provided with for auxiliary hook body 7.Hang to be provided with in box 1 by hinge 3 and be hinged on lock box 4 on its two side, be set with torsion spring 5 on hinge 3, an end of torsion spring 5 contacts with the inner roof wall that hangs box 1, and the other end of torsion spring 5 contacts with the diapire of lock box 4; The free end of auxiliary hook body 7 is provided with dead bolt 8.With reference to Fig. 2 and Fig. 3, described lock box 4, comprise lock box body 41, the lock box body 41 1 end sealing other ends open wide, the end face of lock box body 41 closed ends is dip plane 42, dip plane 42 is provided with the dead bolt insert port 43 near the 41 bottom surfaces settings of lock box body, the diapire of lock box body 41 and two side stretch out from its open end and form open slot 44, the two side of open slot 44 is provided with the hinge axis hole 45 that installs for hinge 3, and lock box 4 is hinged on by the hinge 3 that passes hinge axis hole 45 and hangs box 1 on its two side.

see figures.1.and.2, the end face of lock box body 41 closed ends is dip plane 42, be that lock box body 41 has an end wall that is obliquely installed, dead bolt insert port 43 is located on this end wall that is obliquely installed, when the free end of auxiliary hook body 7 enter by side opening 9 hang box 1 interior after, dead bolt can be attached on the described end wall that is obliquely installed, the auxiliary hook body 7 that continues to overturn can make dead bolt order about on lock box body 41 and turn over, dead bolt just can insert dead bolt insert port 43, remove turning auxiliary hook body 7 application of forces this moment, lock box body 41 resets under the effect of torsion spring 5, the above-mentioned end wall that is obliquely installed just can hook dead bolt, thereby realize self-locking.If need to can insert crowbar by side opening 9 to the dead bolt release, prize lock box body 41 with crowbar and make it to turn over, itself and dead bolt are broken away from.But under the stopping of auxiliary hook body 7, be subjected to space constraint, prize 41 of lock box bodies from side opening requires great effort very much, therefore, can make above-mentioned release work become easier by following measures, namely all establish instrument jack 10 hanging on the relative two sides of box 1, the position of instrument jack 10 will be exposed as standard take lock box 4 bottom surfaces, just can prize lock box body 41 with crowbar insertion tool jack 10.
