Abstract
The present invention relates to a kind of Self-locking hanging hook, and it is made up of coupler body, gib head, closing handle, locking handle, the rotating shaft of closing handle, the rotating shaft of locking handle, torsion spring, shotpin.Closing handle and locking handle are connected on coupler body by closing handle rotating shaft and locking handle rotating shaft respectively, and form the fixed hinge form of two rotary pairs, and two rotary pairs are respectively positioned at the middle part of closing handle and locking handle；Torsion spring is equipped with closing handle rotating shaft and locking handle rotating shaft；The lower outside for closing handle is closely connected with the inner side of ditch head in the presence of torsion spring power；Locking handle top is provided with shotpin, and shotpin is closely connected with the outside of ditch body in the presence of torsion spring power, and shotpin is arranged on limitation closing handle and can not made on the position that inverse spring force direction rotates simultaneously；Shotpin makees disengagable closing handle after inverse spring force direction rotates to an angle in locking handle.The present invention have the advantages that self-locking property is good, be connected firmly, securely and reliably, artificially manipulate it is convenient and simple.
Description
Technical field
It is particularly a kind of to require there is the hook for being perfectly safe and firmly connecting between tether and hook the present invention relates to a kind of Self-locking hanging hook, belong to machinery manufacturing technology field.
Background technology
Existing steel coupling hook also has the security closure for preventing from slipping between attachment, i.e., after attachment is inserted in hook, locking device is implemented to remain silent to hook sleeve porch.But existing locking device not self-locking, it is also possible to the attachment slip phenomenon under complex environment occurs.And this phenomenon is all unallowable under any circumstance.Therefore design it is a kind of have be perfectly safe entangle firm coefficient coupling hook tool be of great significance.
The content of the invention
In order to realize that the hook own wt of lifting cargo is light, load is big, safety coefficient is high, the present invention proposes a kind of Self-locking hanging hook.
Above-mentioned purpose is realized to be implemented by the following technical programs；It is made up of coupler body, gib head, closing handle, locking handle, the rotating shaft of closing handle, the rotating shaft of locking handle, torsion spring, shotpin.The closing handle and locking handle are connected on coupler body by closing handle rotating shaft and locking handle rotating shaft respectively, and form the fixed hinge form of two rotary pairs, and two rotary pairs are respectively positioned at the middle part of closing handle and locking handle；Torsion spring is equipped with the closing handle rotating shaft and locking handle rotating shaft；The lower outside of the closing handle is closely connected with the inner side of ditch head in the presence of torsion spring power；The locking handle top is provided with shotpin, and shotpin is closely connected with the outside of ditch body in the presence of torsion spring power, and shotpin is arranged on limitation closing handle and can not made on the position that inverse spring force direction rotates simultaneously；The shotpin makees disengagable closing handle after inverse spring force direction rotates to an angle in locking handle.
The present invention have the advantages that self-locking property is good, be connected firmly, securely and reliably, artificially manipulate it is convenient and simple.
Brief description of the drawings
Accompanying drawing 1 is the structural representation under present invention closure self-locking state；
Accompanying drawing 2 is the structural representation under present invention opening released state.
In attached Fig. 1 and 2：1 coupler body, 2 closing handles, 3 torsion springs, 4 closing handle rotating shafts, 5 shotpins, 6 locking handle rotating shafts, 7 locking handles, 8 gib heads.
Embodiment
As shown in Figure 1, coupler body 1 is with closing handle 2 by closing the composition revolute of handle rotating shaft 4 and being fixed hinge forms of motion, and revolute is positioned at the middle part of closing handle 2.Inner underside, another end hook that one end due to being provided with torsion spring 3 and torsion spring 3 in closing handle rotating shaft 4 is resisted against closing handle 2 lean against the inner side for closing coupler body 1 below handle rotating shaft 4, thus the lower outside of closing handle 2 can make rotate counterclockwise and closely connected with the inner side of gib head 8 under the twisting force of torsion spring 3 in closing handle rotating shaft 4, so that the opening between coupler body 1 and gib head 8 is completely in full closeding state.In the left side of coupler body 1, coupler body 1 forms revolute by locking handle rotating shaft 6 with locking handle 7 and is fixed hinge forms of motion, and revolute is located at the middle part of locking handle 7.One end due to being provided with torsion spring 3 and torsion spring 3 in locking handle rotating shaft 6 is resisted against the inner underside of locking handle 7, another end hook leans against the outside of coupler body 1 below locking handle rotating shaft 6, again because locking handle 7 is provided with shotpin 5, and shotpin 5 is located at the top of locking handle rotating shaft 6, thus shotpin 5 can rotate and closely connected with the outside 1 of coupler body under the spring force effect of torsion spring 3 around locking handle rotating shaft 6.At the same time, shotpin 5 is also located at forcing closing handle 2 to make the top of closing handle 2 to turn clockwise.Therefore when the accidental external force of appearance acts on the outside of closing handle 2 and forces closing handle 2 to turn clockwise, shotpin 5 hinders the rotating tendency of closing handle 2, it is achieved thereby that can not unlock opening purpose under non-artificial state between coupler body 1 and gib head 8.As shown in Figure 2, when needing to be in opening released state between coupler body 1 and gib head 8, then locking handle 7 is imposed to the outer downside of locking handle 7 first and makees the power around the rotate counterclockwise of locking handle rotating shaft 6, so that shotpin 5 disengages closing handle 2.Handle 2 is now closed to be under no restraint on direction turning clockwise, as long as therefore in the outside force of closing handle 2, closing the upper and lower part of handle 2 can turn clockwise around closing handle rotating shaft 4, realize that the opening under artificiality unlocks purpose.
