Technical Field

The utility model relates to an electric power fitting field, concretely relates to bird shape wire drawing hook.

Background

The stay wire hook has holding rod and hook to constitute, mainly is applied to cable installation, maintenance in-process, when the height is not enough or construction environment is dangerous, grips the holding rod, manipulates the hook and pulls the cable, but current stay wire hook structure is too simple, can not adjust the length of holding rod in a flexible way and adapt to different altitude requirement, and the whole overlength of stay wire hook is difficult to nimble operation or whole overlength is difficult to draw the cable of pulling more eminence.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a bird-shaped wire drawing hook which is simple in operation and can flexibly adjust the length.

The utility model discloses a following technical scheme realizes: the bird-shaped wire drawing hook comprises a holding rod and a claw fixed at the front end of the holding rod, wherein a connecting sleeve is arranged at the rear end of the holding rod and is connected with the holding rod and an extension assembly, the extension assembly comprises a sleeve rod and an extension rod penetrating through the sleeve rod, a piston is arranged at the bottom of the extension rod, the top of the extension rod is fixedly connected with the connecting sleeve, and compressed nitrogen is sealed between the piston and the bottom of the sleeve rod;

the outer wall of the sleeve rod is provided with a through hole with internal threads, a screw rod is arranged in the through hole in a matched mode, and the screw rod penetrates through the through hole and props the extension rod.

The outer wall of the extension rod is provided with a containing groove, the notch of the containing groove faces the screw rod, the inner wall of the loop bar is annularly provided with a limiting ring, and the limiting ring is located below the through hole.

The bottom of the loop bar is fixed with a magnet piece, and the magnet piece is attracted by magnetic force and is provided with a balancing weight.

The middle part of magnet piece is equipped with the guide post, the axis of guide post with the axis coincidence of loop bar, the middle part of balancing weight is equipped with the through-hole, the guide post is worn to establish in the through-hole.

Compared with the prior art, the utility model has the advantages that when in work, the screw rod is unscrewed, the locking effect of the screw rod on the extension rod is removed, at the moment, the compressed nitrogen expands and pushes the extension rod to extend out of the loop bar, so that the overall length of the stay wire hook is prolonged; in the process that the extension rod stretches out, the screw rod can be screwed again at any time, the extension rod is locked, and therefore after the extension length of the extension rod is enough, the overall length of the wire drawing hook is controlled, flexible adjustment is achieved, and the operability of the wire drawing hook is improved to the maximum extent.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-3, the bird-shaped wire drawing hook comprises a holding rod 1 and a claw 2 fixed at the front end of the holding rod 1, wherein a connecting sleeve 3 is arranged at the rear end of the holding rod 1, the connecting sleeve 3 is connected with the holding rod 1 and an extension component 4, the extension component 4 comprises a sleeve rod 5 and an extension rod 6 penetrating through the sleeve rod 5, a piston 7 is arranged at the bottom of the extension rod 6, the top of the extension rod is fixedly connected with the connecting sleeve 3, and compressed nitrogen is sealed between the piston 7 and the bottom of the sleeve rod 5; the connecting sleeve 3 is of a hollow tubular structure, the holding rod 1 and the extension rod 6 are respectively inserted from two ends of the connecting sleeve 3, and finally the holding rod 1, the connecting sleeve 3 and the extension rod 6 are fixedly connected by welding, riveting or screws;

the outer wall of the loop bar 5 is provided with a through hole 8 with internal threads, a screw rod 9 is arranged in the through hole 8, and the screw rod 9 penetrates through the through hole 8 and props the extension bar 6. When the extension assembly 4 is in a non-working state, the screw 9 is screwed, the screw 9 extrudes the extension rod 6, the extension rod 6 is in a static and fixed state, nitrogen is in a compressed state, when the original length of the holding rod 1 is not enough, the extension assembly 4 works, the screw 9 is unscrewed, the locking effect of the screw 9 on the extension rod 6 is removed, at the moment, the compressed nitrogen expands, the extension rod 6 is pushed to extend out of the loop rod 5, and the whole length of the wire drawing hook is extended; furthermore, because the expansion of nitrogen and the extension of the extension rod 6 are relatively slow processes, when the extension rod 6 extends out to a sufficient length, the screw rod 9 is screwed again and the extension rod 6 is locked, so that the length of the whole stay wire hook is controlled after the extension length of the extension rod 6 is ensured to be sufficient, the stay wire hook is flexibly adjusted, and the operability of the stay wire hook is improved to the maximum extent.

The outer wall of the extension rod 6 is provided with a containing groove 10, the notch of the containing groove 10 faces the screw rod 9, the inner wall of the loop bar 5 is annularly provided with a limiting ring 11, and the limiting ring 11 is located below the through hole 8. When the extension assembly 4 is in a non-working state, the containing groove 10 is flush with the through hole 8, and the screw 9 penetrates through the through hole 8 and then extends into the containing groove 10, so that the screw 9 can reliably lock the extension rod 6; after the piston 7 touches the limiting ring 11, the extension rod 6 stops moving, the nitrogen is still in a compressed state, but the pressure is lower than the initial pressure, so that the nitrogen still has a pushing effect on the extension rod 6 when in the maximum extension state, the overall connection firmness of the stay wire hook is improved, and the extension rod 6 is prevented from easily retracting when in use.

The bottom of the loop bar 5 is fixed with a magnet piece 12, and a balancing weight 13 is attracted on the magnet piece 12 through magnetic force. The counterweight block 13 is arranged, so that on one hand, the overall weight of the stay wire hook is increased, the stay wire hook is more labor-saving when the cable is pulled downwards, on the other hand, when the extension component 4 needs to be recovered after use, the stay wire hook is caused, and the extension rod 6 can be rapidly and labor-saving recovered and locked under the action of the sleeve rod 5 gravity, the counterweight block 13 gravity and artificial pressing force; further, be connected through magnetic force between balancing weight 13 and the magnet piece 12, can conveniently, adjust the quantity of balancing weight 13 fast to adapt to different operation demands more fast.

The middle part of magnet piece 12 is equipped with guide post 14, the axis of guide post 14 with the axis coincidence of loop bar 5, the middle part of balancing weight 13 is equipped with the through-hole, guide post 14 wears to establish in the through-hole. The guide posts 14 serve as a guide and a limit function when the counterweight block 13 is assembled, and prevent the connection between the counterweight block 13 and the magnet piece 12 from being damaged when being held.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
