Abstract
The utility model relates to a self-locking hook capable of being used conveniently. The self-locking hook comprises a hook body, fixing shafts arranged on the two sides of the tail portion of the hook body, and a lock petal hinged to the hook body through the fixing shafts. The top end of the lock petal is arranged in a groove in the inner side of the front end of the hook body. Two connecting arms are arranged on the lock petal and are respectively hinged to a connecting ring. Torsion springs are arranged on the fixing shafts in a sleeved mode. According to the self-locking hook, a self-locking device is arranged, so that the self-locking hook is safe, reliable, and simple and convenient to operate at utilization time; the top end of the lock petal is arranged in the groove so as not to be capable of breaking open at utilization time; the connecting arms are arranged on the lock petal, and the lock petal can be opened as long as the connecting arms are pulled and dragged, so that utilization is convenient.
Description
Technical field
The utility model relates to a kind of convenient Self-locking hanging hook used.
Background technique
At present, in the insulator string work of changing 500kV EHV transmission lines road, after need to connecting suspension rod with leading screw, replace insulator to be connected with wire, play the effect of fixing cord.Usually, leading screw is connected by U-loop with suspension rod, and U-loop need to be fixed with bolt, the staff when high-lift operation, due to limited space, the one-man service, need portable a suspension rod (heavily about 30-35 jin), dismounting on the other hand, and in the glove situation of wearing, the bolt of dismounting U-loop is inconvenience extremely, and movement range is larger, the activity duration is long, inefficiency, high to operating personnel's physical fitness requirement, there is potential safety hazard.In this case, usually need two people's coordinating operations, just can complete associative operation.For addressing the above problem, we need to replace with device easy and simple to handle U-shaped ring to connect suspension rod and leading screw.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of Self-locking hanging hook that can connect the simple in structure of suspension rod and leading screw and the convenient use that Security is higher.
The utility model adopts following technological scheme:
The utility model comprises the hook main body, is arranged on the stationary axle of hook main body two sides of tail and the lock lobe be hinged by stationary axle and hook main body, and described hook body front end inboard is provided with groove, and the top of described lock lobe is placed in groove; Be provided with two link arms on described lock lobe, described two link arms are hinged with connecting ring respectively; Be provided with two torsion springs between described hook main body and described lock lobe, described two torsion springs are nested with respectively on two stationary axle; The bottom of described hook main body is provided with connecting base, and described connecting base bottom is provided with threaded connection hole.
Can be provided with stay cord on connecting ring described in the utility model.
Good effect of the present utility model is as follows:
While using the utility model, main body will be linked up with and leading screw links together by the threaded connection hole that is arranged on connecting base bottom, because lock lobe and hook main body are hinged by stationary axle, and the two ends of the torsion spring be nested with on stationary axle are respectively against on lock lobe and hook main body, like this under the effect of external force, the lock lobe rotates to the hook main body is inboard, the hook opening opens, together with link on suspension rod buckles, then under the effect of torsion spring, lock lobe appliance for releasing single is got back to original position, to link up with opening pins, safe and reliable, simple to operate, reduce high-altitude personnel's workload, increase work efficiency.
Because the top of locking lobe is placed in the groove of hook body front end inboard, lock like this lobe and both be not easy outwards to collapse out, also be not easy to be pried open by the object accident be connected with hook, greatly increased the safety coefficient of hook; Owing on the lock lobe, being provided with two link arms, connecting ring is hinged with two link arms respectively, after finishing using, pulls down and is dynamically connected ring or pulls stay cord, and the lock lobe inwardly rotates, and the hook opening opens, and without with hand pressing lock lobe, just hook can be taken.
Use the utility model to connect suspension rod and leading screw, no matter buckle or dismantle, operate all very easyly, and Security is higher, has alleviated high-lift operation personnel's burden.
The accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is for being provided with the torsion spring structural representation between the utility model hook main body and lock lobe;
Accompanying drawing 3 is provided with the threaded connection hole structural representation for the utility model connecting base bottom.
In the accompanying drawings: 1 hook main body, 2 grooves, 3 lock lobes, 4 stationary axle, 5 connecting bases, 6 leading screws, 7 torsion springs, 8 threaded connection holes, 9 connecting rings, 10 link arms.
Embodiment
As accompanying drawing 1 ~ 3 is depicted as specific embodiment of the utility model, the utility model comprises hook main body 1, is arranged on the stationary axle 4 of hook main body 1 two sides of tail and the lock lobe 3 be hinged by stationary axle 4 and hook main body 1, described hook main body 1 front end inboard is provided with groove 2, and the top of described lock lobe 3 is placed in groove 2; Be provided with two link arms 10 on described lock lobe 3, described two link arms 10 are hinged with connecting ring 9 respectively; Be provided with two torsion springs 7 between described hook main body 1 and described lock lobe 3, described two torsion springs 7 are nested with respectively on two stationary axle 4; The bottom of described hook main body 1 is provided with connecting base 5, and described connecting base 5 bottoms are provided with threaded connection hole 8; Can be provided with stay cord on described connecting ring 9.
As shown in Figure 1, while using the utility model, to link up with main body 1 by the threaded connection hole 8 that is arranged on connecting base 5 bottoms links together with leading screw 6, because lock lobe 3 and hook main body 1 are hinged by stationary axle 4, and the two ends of the torsion spring 7 be nested with on stationary axle 4 are respectively against on lock lobe 3 and hook main body 1, like this under the effect of external force, lock lobe 3 rotates to hook main body 1 is inboard, the hook opening opens, together with link on suspension rod buckles, then under the effect of torsion spring 7, lock lobe 3 appliance for releasing singles are got back to original position, to link up with opening pins, safe and reliable, simple to operate, reduce high-altitude personnel's workload, increase work efficiency.
Because the top of locking lobe 3 is placed in the groove 2 of hook main body 1 front end inboard, lock like this lobe 3 and both be not easy outwards to collapse out, also be not easy to be pried open by the object accident be connected with hook, greatly increased the safety coefficient of hook; Owing on lock lobe 3, being provided with two link arms 10, connecting ring 9 is hinged with two link arms 10 respectively, after finishing using, pulls down and is dynamically connected ring 9 or pulls stay cord, and lock lobe 3 inwardly rotates, and the hook opening opens, and without with hand pressing lock lobe 3, just hook can be taken.
Use the utility model to connect suspension rod and leading screw, no matter buckle or dismantle, operate all very easyly, and Security is higher, has alleviated high-lift operation personnel's burden, and reduction labor intensity, can effectively increase work efficiency.
