Description

Safety hook

Technical field

The utility model relates to a kind of suspension hook, in particular for the safety hook of the weight of slinging.

Background technology

At present, domestic the building or the lifting industry in be extensive use of suspension hook, it is carrying weight by hook, to be on the safe side, dead bolt is housed on hook, switch for the ease of dead bolt, people have designed the mechanism of many restriction dead bolt switches, but because these mechanisms are comparatively complicated in operation, and self-locking is relatively poor, in case danger occurs, its consequence is difficult to the imagination.

Summary of the invention

The present utility model purpose is the self-locking problem that solves suspension hook, and a kind of safety hook is provided.

For achieving the above object, the utility model adopts following design plan: a kind of safety hook of the present utility model,

A kind of safety hook of the present utility model, it comprises: hook, dead bolt, suspension ring, bearing pin and adapter shaft, dead bolt inserts in the hook by adapter shaft, and is riveted together by bearing pin and hook, and suspension ring link to each other with adapter shaft; Wherein: it also comprises: pull bayonet lock, straight pin, spring, clamp and slotted countersunk flat head screw, pull bayonet lock and straight pin is fixed together, straight pin penetrates in the hole of spring and clamp, clamp is fixed together by slotted countersunk flat head screw and hook, an end that pulls bayonet lock moves in clamp, the other end is blocked by the top of dead bolt, regulates dead bolt and rotates;

A kind of safety hook of the present utility model, wherein: the described top that pulls bayonet lock is a conical end, and the top of dead bolt has groove, and conical end is blocked by the groove of the top of dead bolt;

A kind of safety hook of the present utility model, wherein: described spring is installed in and pulls between bayonet lock and the clamp;

A kind of safety hook of the present utility model, wherein: described suspension ring are contained on the adapter shaft, and by hexagon slotted nut and packing ring suspension ring and adapter shaft are spun together;

A kind of safety hook of the present utility model, wherein: described suspension ring are the U type, and it and adapter shaft are one, and the both sides of the U type opening of suspension ring respectively have a hole, and bolt passes above-mentioned two holes, will be bolted on the suspension ring with spring cotter.

The utility model safety hook is compared with employed suspension hook in the market, and is more convenient to operate, use safelyr, is the good assistant of building and lifting industry.

Description of drawings

Fig. 2 is the forward scheme drawing of the utility model safety hook second embodiment;

The specific embodiment

Embodiment 1

As shown in Figure 1, a kind of safety hook, it comprises: suspension ring 1, hook 4, dead bolt 10, bearing pin 3 and adapter shaft 2, dead bolt 10 insertion adapter shafts 2 backs are inserted together in the hook 4 and by bearing pin 3 and hook 4 with adapter shaft 2 and are riveted together; Safety hook also comprises: pull bayonet lock 5, straight pin 6, spring 7, clamp 8 and slotted countersunk flat head screw 9, pull bayonet lock 5 and straight pin 6 is fixed together, straight pin 6 penetrates in the hole of spring 7 and clamp 8, be installed in and pull between bayonet lock 5 and the clamp 8, clamp 8 is fixed together by slotted countersunk flat head screw 9 and hook 4, an end that pulls bayonet lock 5 moves in clamp 8, the top of its other end is a conical end 15, the top of dead bolt 10 has groove 16, conical end 15 is blocked by the groove 16 of the top of dead bolt 10, is used to regulate dead bolt 10 and rotates.。

Suspension ring 1 are contained on the adapter shaft 2, and by hexagon slotted nut 12 and packing ring 11 suspension ring 1 and adapter shaft 2 are spun together, and suspension ring 1 are used to collude the hook of hanging up heavy-duty machine.

Embodiment 2:

As shown in Figure 2, this embodiment is substantially the same manner as Example 1, identical part is not repeated, identical parts have used identical numbering, and different is: suspension ring 1 change into and are U type opening, and U type opening and adapter shaft 2 become one, the both sides of U type opening respectively have a hole, bolt 13 passes above-mentioned two holes, with spring cotter 14 bolt 13 is fastened on the suspension ring 1, and bolt 13 is used to collude the hook of hanging up heavy-duty machine.

When safety hook is started working, user's pulling pulls bayonet lock 5, pull bayonet lock 5 drive straight pins 6 hole of hook 4 and clamp 8 move down to the right, the conical end 15 that pulls bayonet lock 5 withdraws from from dead bolt groove 16, at this moment, dead bolt 10 can be around bearing pin 3 clickwises, and the user can carry out loading or unloading with goods in the ring that hook 4 and dead bolt 10 are surrounded; When safety hook begins to sling goods, unclamp and pull bayonet lock 5, because the effect of spring 7, the conical end 15 that pulls bayonet lock 5 upwards inserts dead bolt groove 16, dead bolt is locked; Make the dead bolt 10 can not be, the goods of lifting is pinned tightly in the ring that hook 4 and dead bolt 10 are surrounded around bearing pin 3 clickwises.

More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, the utility model can be done any type of modification.
