Automatically open locking bar.
In order to realize the purpose of this utility model, intend using following technical scheme：
A kind of safety hook equipped with anti-drop device, including suspension hook, connecting cylinder and locking bar：
Connecting cylinder top plate is equipped with hanging ring, and snap-gauge is equipped in connecting cylinder, connects tube end plate and snap-gauge is equipped with through hole, suspension hook
Shank is inserted through hole, and suspension hook shank top is equipped with handle cap, and handle cap is stuck in above snap-gauge；Suspension hook shank close to the side of bill and
Its offside is equipped with a pair of of rack, this coordinates rack with a pair of of the gear for being hung at connecting cylinder bottom by otic placode；It is remote on locking bar
One end of off-hook point is equipped with two-arm, and locking bar two-arm is fixedly folded in the gear both sides far from bill side.
Further, the distance that handle cap moves up and down in connecting cylinder is the 1/7 ~ 1/5 of pitch circle perimeter.
Further, the two-arm of locking bar is pyriform.
Further, the top plate of connecting cylinder is designed as thickening top plate, or object block of the setting for weightening on top plate.
The utility model has the beneficial effects that：
1, can realize be closed locking bar automatically when lifting weight, unload weight after automatically open locking bar, can effectively carry
High production operation efficiency mitigates the labor intensity of labour personnel；
When 2, opening locking bar, locking bar is rotated outside suspension hook, be can effectively solve the problem that and is designed locking bar in the prior art to suspension hook
In the case of interior rotation, when the weight that is hooked in suspension hook or excessive rope body, the problem of easily blocking locking bar.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
The utility model belongs to hoisting machinery technical field, is related to a kind of safety hook equipped with anti-drop device, as Fig. 1,
Shown in Fig. 2, including suspension hook 1, connecting cylinder 2 and locking bar 3：
2 top plate of connecting cylinder is equipped with hanging ring 21, is equipped with snap-gauge 22 in connecting cylinder 2,2 bottom plate of connecting cylinder and snap-gauge 22 are equipped with
Through hole, 1 shank of suspension hook are inserted through hole, and 1 shank top of suspension hook is equipped with handle cap 11, and handle cap 11 is stuck in 22 top of snap-gauge；Suspension hook 1
Shank is equipped with a pair of of rack 12 close to the side of bill and its offside, this is hung at connecting cylinder 2 to rack 12 and by otic placode 23
A pair of of gear 24 of bottom coordinates；One end far from bill is equipped with two-arm 31 on locking bar 3, and locking bar two-arm 31 is fixedly folded in far
24 both sides of gear of off-hook point side.
The operation principle of the utility model is as follows：
Weight is hung in suspension hook 1, lifting rope is connected on hanging ring 21, and lifting rope pulls connecting cylinder 2 to move up on crane, even
The gear 24 being connected on connecting cylinder 2 is moved up along the rack 12 of 1 shank of suspension hook, and gear 24 is generated during moving up and rotated counterclockwise,
The locking bar 3 being fixedly connected with gear 24 is driven to rotate counterclockwise simultaneously, locking bar 3 is fastened at the bill of suspension hook 1, to prevent
Weight breaks off relations；Weight is hung to when needing to be put down behind target location, transfers lifting rope, connecting cylinder 2 is under the effect of gravity
It moves down, gear 24 also moves down therewith, and gear 24 rotates clockwise, and drives locking bar 3 to rotate clockwise, that is, opens button
Close the locking bar 3 on the bill of suspension hook 1.
The utility model in use, locking bar 3 can be closed automatically when lifting weight, unload weight after automatically open
Locking bar 3 can effectively improve production operation efficiency, mitigate the labor intensity of labour personnel；Meanwhile when opening locking bar 3, locking bar 3
It is to be rotated outside suspension hook, can effectively solve the problem that and locking bar 3 is designed as in the case of being rotated into suspension hook 1 in the prior art, when hanging
When the weight or excessive rope body that hook in hook 1, the problem of easily blocking locking bar 3.
It, can be it is further preferable that handle cap 11 moves down on connecting cylinder 2 is interior to advanced optimize the using effect of the utility model
Dynamic distance is the 1/7 ~ 1/5 of 24 pitch circumference of gear；In this way, the maximum angle of opening locking bar 3 can be made to be about 50 ° ~ 70 °, carry
For enough open angles to ensure that weight or rope body are successfully linked into suspension hook 1 or the taking-up out of suspension hook 1.
It, can be it is further preferable that as shown in figure 3, by the two-arm of locking bar to advanced optimize the using effect of the utility model
31 are designed as pyriform, make have enough spaces between the two-arm of locking bar 3, ensure that locking bar 3 does not produce in rotation process with 1 shank of suspension hook
Raw friction, or stopped and cannot normally be rotated by 1 shank of suspension hook.
It, can be it is further preferable that the top plate of connecting cylinder 2 be designed as thickening to advanced optimize the using effect of the utility model
Top plate, or object block of the setting for weightening on 2 top plate of connecting cylinder, in this way, when can make decentralization weight, connecting cylinder 2 has enough
Its own gravity makes it move down automatically, to ensure that locking bar 3 can be automatically opened successfully.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, under the premise of not departing from utility model design, various modifications and improvements can be made, these belong to this reality
With novel protection domain.
