Abstract
The utility model relates to a light-weight heavy-load self-locking hook which comprises a hook body, a hook head, a closing handle, a locking handle, a closing handle spindle, a locking handle spindle, torsion springs and a stop pin, wherein the closing handle and the locking handle are respectively connected to the hook body by the closing handle spindle and the locking handle spindle to form the fixed hinge forms of two rotary pairs, and the two rotary pairs are respectively positioned in the middle parts of the closing handle and the locking handle; the torsion springs are respectively arranged on the closing handle spindle and the locking handle spindle; the outer side at the lower part of the closing handle can be tightly attached to the inner side of the hook head under the action of the torsion spring force; the stop pin is arranged at the upper part of the locking handle, the stop pin can be tightly attached to the outer side of the hook body under the action of the torsion spring force, and the stop pin is simultaneously arranged in such a position that the closing handle is limited and can not rotate in the inverse direction of the torsion spring force; and the stop pin can release the closing handle after the locking handle rotates a certain angle in the inverse direction of the torsion spring force. The utility model has the advantages of favorable self-locking performance, stable connection, high safety and reliability and the like, and is convenient and easy to manually control.
Description
Technical field
The utility model relates to a kind of light-duty heavy load self-locking to be linked up with, and particularly a kind of the requirement must have the hook that is perfectly safe and firmly is connected between tether and the hook, belongs to machinery manufacturing technology field.
Background technique
Existing steel coupling hook also have prevent and fastening between the security closure of slippage, promptly in fastening is inserted in hook after, locking device is implemented to overlap remaining silent of ingress to linking up with.But the not self-locking of existing locking device also may occur in the fastening slip phenomenon under the complex environment.And this phenomenon under any circumstance all is unallowable.Therefore design and a kind ofly have the coupling hook that entangles coefficient firm that is perfectly safe and have crucial meaning.
Summary of the invention
Light for the hook own wt of realizing lifting cargo, load is big, safety coefficient is high, the utility model proposes a kind of light-duty heavy load self-locking hook.
Above-mentioned purpose realizes implementing by the following technical programs; It is made up of coupler body, gib head, sealing handle, locking handle, the rotating shaft of sealing handle, the rotating shaft of locking handle, torsion spring, shotpin.Described sealing handle and locking handle are connected on the coupler body by sealing handle rotating shaft and the rotating shaft of locking handle respectively, and form the fixed hinge form of two rotary pairs, and two rotary pairs lay respectively at the middle part of sealing handle and locking handle; Be equipped with torsion spring in rotating shaft of described sealing handle and the rotating shaft of locking handle; The outside, the bottom of described sealing handle inboard closely connected with the ditch head under the effect of torsion spring power: described locking handle top is provided with shotpin, shotpin is closely connected with the outside of ditch body under the effect of torsion spring power, and shotpin is arranged on restriction sealing handle simultaneously and can not does on the position of contrary spring force direction rotation; Described shotpin is done can throw off the sealing handle after contrary spring force direction rotates to an angle at the locking handle.
The utlity model has self-locking property good, be connected firmly, safe and reliable, people is for controlling advantages such as convenient and simple.
Description of drawings
Accompanying drawing 1 is the structural representation under the closed self-locking state of the utility model;
Accompanying drawing 2 is the structural representation under the utility model opening released state.
In attached Fig. 1 and 2: 1 coupler body, 2 sealing handles, 3 torsion springs, 4 sealing 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 constitutes revolute with sealing handle 2 by sealing handle rotating shaft 4 and is the fixed hinge forms of motion, and revolute is positioned at the middle part of sealing handle 2.Because the inboard of coupler body 1 below inner underside, another end hook that an end that is provided with torsion spring 3 and torsion spring 3 in the sealing handle rotating shaft 4 is resisted against sealing handle 2 lean against the rotating shaft 4 of sealing handle, thereby the bottom outside of sealing handle 2 can be rotated counterclockwise under torsion spring 3 twisting forces in the sealing handle rotating shaft 4 and inboard closely connected with gib head 8, thereby make the opening between coupler body 1 and the gib head 8 be in full closeding state fully.In the left side of coupler body 1, coupler body 1 constitutes revolute with locking handle 7 by locking handle rotating shaft 6 and is the fixed hinge forms of motion, and revolute is positioned at the middle part of locking handle 7.Because the outside of coupler body 1 below inner underside, another end hook that an end that is provided with torsion spring 3 and torsion spring 3 in the locking handle rotating shaft 6 is resisted against locking handle 7 lean against the rotating shaft 6 of locking handle, again because locking handle 7 is provided with shotpin 5, and shotpin 5 is positioned at the top of locking handle rotating shaft 6, thereby shotpin 5 can be around locking handle rotating shaft 6 rotations and closely connected with the outside 1 of coupler body under the spring power effect of torsion spring 3.Meanwhile, shotpin 5 also is positioned at sealing handle 2 tops that force sealing handle 2 to do to turn clockwise.Therefore when accidental external force occurring and act on the outside of sealing handle 2 and force sealing handle 2 to turn clockwise, shotpin 5 has hindered and has sealed the rotation trend of handle 2, thus realized between coupler body 1 and the gib head 8 under non-artificial state can not release opening purpose.As shown in Figure 2, when being in the opening released state between needs coupler body 1 and the gib head 8, then first outer downside to locking handle 7 imposes the power that locking handle 7 works are rotated counterclockwise around locking handle rotating shaft 6, ends 5 disengagement sealing handles 2 thereby make.Seal handle 2 and be under no restraint on the dextrorotation veer this moment, and as long as therefore in the outside application of force of sealing handle 2, the upper and lower part of sealing handle 2 just can turn clockwise around sealing handle rotating shaft 4, realizes the opening release purpose under the artificiality.
Claims (4)
1. a light-duty heavy load self-locking is linked up with, coupler body, gib head, sealing handle, locking handle, the rotating shaft of sealing handle, the rotating shaft of locking handle, torsion spring, shotpin constitute, it is characterized in that coupler body is provided with sealing handle and locking handle, and rotating shaft is connected with coupler body with the locking handle by the rotating shaft of sealing handle respectively; Described sealing handle and locking handle and sealing handle rotating shaft and the rotating shaft of locking handle form the fixed hinge form of two rotary pairs, and two rotary pairs lay respectively at the middle part of sealing handle and locking handle.
