Abstract
The utility model discloses a small tightener for a service wire, which comprises a hook, an adjusting instrument and a cable chain used for connecting the hook and the adjusting instrument; the adjusting instrument comprises a hook provided with an external threaded rod, an adjusting sleeve and a joint lever; the external threaded rod of the hook is matched with an internal thread arranged in one end of the adjusting sleeve; the other end of the adjusting sleeve is matched with one end of the joint lever; the other end of the joint lever is connected with the cable chain; the adjusting sleeve and the joint lever are connected by matched threads; twist grips are arranged on the rod of the hook and the outer wall of the adjusting sleeve; a plurality of hooks are arranged on the cable chain; the total length of the tightener is shortened by converting the rotating motion of the twist grips, the hooks and the adjusting sleeve into linear motion, thereby achieving the goal of straightening bent service wires.
Description
Technical field
This use is novel to relate to a kind of instrument of straining beformable body class workpiece, especially a kind ofly is used for the small-sized wire grip that electric power, telecommunication connection construction tension service wire are used.
Background technology
The power transmission line wire grip is a kind of common tool of power circuit construction and maintenance, it is used that existing power transmission line wire grip mostly is the electric pole stringing, if for the circuit of registering one's residence with common power transmission line wire grip, because its volume is bigger, weight is bigger, and scope of activities is bigger during work, carry inconvenience, labour intensity is big when causing the workmen to use, inefficiency, even can not use.
The utility model content
It is less, easy to carry that the purpose of this utility model provides a kind of volume, can improve the small-sized wire grip at the line applications of registering one's residence of workman's working condition.
To achieve these goals, the small-sized wire grip of service wire of the present utility model comprises hook, adjusting device and is used for coupling hook and the rope chain of adjusting device, adjusting device comprises hook, adjustment cover and the connecting rod that has external thread rod, the external thread rod of hook matches with the internal thread of the interior setting of adjusting cover one end, the other end of adjusting cover is equipped mutually with an end of connecting rod, and the other end of connecting rod and rope chain link.
As improvement of the present utility model, adjusting cover is to connect by the screw thread that matches with connecting rod.
As improvement of the present utility model, on the shank of hook, adjust on the outer wall of cover and can be respectively arranged with rotary handle.
As further improvement of the utility model, on the rope chain, can be provided with a plurality of hooks.
Adopt the small-sized wire grip of this novel service wire, because it is simple in structure, easy to use, is convenient to the workmen and carries, operation very easily just can reach the purpose of stringing.
Description of drawings
Describe embodiment of the present utility model below with reference to accompanying drawings in detail.
Fig. 1 is first kind of execution mode structure chart of the present utility model.
Fig. 2 is second kind of novel execution mode structure chart of this use.
According to Fig. 1 as can be known, the utility model comprises hook 1, adjusting device 2 and is used for coupling hook 1 and the rope chain 3 of adjusting device 2, adjusting device 2 comprises hook 21, adjustment cover 22 and the connecting rod 23 that has external thread rod, the external thread rod of hook 21 matches with the internal thread of the interior setting of adjusting cover 22 1 ends, the other end of adjusting cover 22 is equipped mutually with an end of connecting rod 23, and the other end of connecting rod 23 and rope chain 3 link.
According to Fig. 2 as can be known, adjusting cover 22 in the utility model is a kind of execution modes that connect by the screw thread that matches with connecting rod 23.
Among Fig. 1 and Fig. 2, at the hook that has external thread rod 21 of adjusting device 2 with have on the internal thread adjustment cover 22 rotary handle 24,25 is installed.
During use, hook 2 is hung over and is positioned on the fixed mount that is used for fixing service wire one end on the wall, this moment, one end of service wire was fixed on this fixed mount, service wire from another adjacent fixed mount turn back and be connected with the hook 21 that has external thread rod, by rotary handle 24,25, the adjustment cover 22 that has the hook 21 of external thread rod and cooperate with it shortens the total length of wire grip by the conversion rectilinear motion that rotatablely moves, thereby stretching crooked service wire.
