Abstract

The utility model relates to a locking hook for a ground wire. The locking hook comprises a hook head and a hook rod, wherein the hook head and the hook rod are mutually connected. A hook seat opposite to the hook head is fixedly connected with the lower portion of the hook rod; a guide sliding block is installed at the hook rod; and a moving top block is arranged between the hook seat and the hook head and is fixed at the guide sliding block. A transmission worm parallel to the axis of the hook rod is arranged at the hook seat; a bolt connected with the moving top block is inserted into the transmission worm; a thread cooperating with the bolt is arranged at the inner wall of the transmission worm; a worm wheel cooperating with the transmission worm is arranged at the hook seat; and an insulated handle for driving the worm wheel to rotate is arranged at the worm wheel. According to the scheme, the moving top block is arranged and the ground wire is clamped tightly based on cooperation with the hook head, so that good contact between the ground wire and the lead is ensured; the worm wheel, the transmission worm and the bolt are arranged, so that the moving top block can move conveniently and thus the self-locking function of the device can be ensured.

Description

Locking hook for a kind of earth connection
Technical field
The utility model relates to power engineering field, particularly locking hook for a kind of earth connection.
Background technology
In order to prevent that the induced voltage in the unexpected incoming call of dead line or circuit from refluxing, need to carry out electrical verification trouble-shooting to power circuit, and before electrical verification, need hanging earthing conductor, avoid personnel in electrical verification process, to have the potential safety hazards such as electric shock.In prior art, because of tower structure pattern difference, what have need to be at hanging earthing conductor under level, and there is angle problem in conventional clamp for ground wire form, be difficult to realize under level earth connection is installed, and traditional ground wire connecting device adopts non-fastening-type, will there is the problem that flow conductivity is poor, contact is relaxed.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, guarantees that earth connection contact well with wire, has auto-lock function, and the locking that realizes different angles installation and horizontally suspend earth connection is linked up with.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of earth connection locking hook, comprise interconnective gib head and shank, the bottom of shank is fixedly connected with the hook base being oppositely arranged with gib head, be characterized in, on described shank, guide runner is housed, between described hook base and gib head, be provided with mobile jacking block, mobile jacking block is fixed on guide runner, on described hook base, be provided with the transmission worm screw be arrangeding in parallel with shank axis, in transmission worm screw, be inserted with the bolt joining with mobile jacking block, on the inwall of transmission worm screw, be provided with the screw thread matching with bolt, on described hook base, be provided with the turbine coordinating with transmission worm screw, turbine is provided with the insulated handle that drives turbine rotation.
Technical problem to be solved in the utility model can also further realize by following technical scheme, in above-described earth connection is linked up with locking: be provided with on described mobile jacking block and coordinate the deep-slotted chip breaker that clamps earth connection with gib head.
The utility model, by establishing mobile jacking block, coordinates with gib head and clamps earth connection, guarantees that earth connection contacts with wire well, can not relax.By establishing turbine, transmission worm screw and bolt, easily promote mobile jacking block and move up and down, and there is good auto-lock function, on turbine, establish insulated handle, drive turbine rotation, easy to operate.By establishing guide runner, guide runner is connected with mobile jacking block, and mobile jacking block can not be misplaced, and also can not swing.Compared with prior art, it is reasonable in design, easy to use, has good auto-lock function, guarantees that earth connection contacts well with wire, has realized the installation of different angles and has horizontally suspended earth connection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to Fig. 1, locking hook for a kind of earth connection, comprise interconnective gib head 4 and shank 5, the bottom of shank 5 is fixedly connected with the hook base 2 being oppositely arranged with gib head 4, on described shank 5, guide runner 6 is housed, between described hook base 2 and gib head 4, be provided with mobile jacking block 3, mobile jacking block 3 is fixed on guide runner 6, on described hook base 2, be provided with the transmission worm screw 10 be arrangeding in parallel with shank 5 axis, in transmission worm screw 10, be inserted with the bolt 9 joining with mobile jacking block 3, on the inwall of transmission worm screw 10, be provided with the screw thread matching with bolt 9, on described hook base 2, be provided with the turbine 8 coordinating with transmission worm screw 10, turbine 8 is provided with the insulated handle 7 that drives turbine 8 to rotate.
On described mobile jacking block 3, be provided with gib head 4 and coordinate the deep-slotted chip breaker that clamps earth connection.
The gib head of hook 4 is hung on earth connection, by insulated handle 7, turbine 8 is rotated, thereby drive transmission worm screw 10 to move in a circle, transmission worm screw 10 rotarily drives bolt 9 and carries out elevating movement, and under the guiding of guide runner 6, the glide direction of mobile jacking block 3 is parallel with the axis of shank 5, realizing mobile jacking block 3 coordinates clamping earth connection or exits clamped condition with gib head 4, there is auto-lock function, also can make earth connection contact with wire well, easy and simple to handle.

Claims (2)

1. a locking hook for earth connection, comprise interconnective gib head and shank, the bottom of shank is fixedly connected with the hook base being oppositely arranged with gib head, it is characterized in that: on described shank, guide runner is housed, between described hook base and gib head, be provided with mobile jacking block, mobile jacking block is fixed on guide runner, on described hook base, be provided with the transmission worm screw be arrangeding in parallel with shank axis, in transmission worm screw, be inserted with the bolt joining with mobile jacking block, on the inwall of transmission worm screw, be provided with the screw thread matching with bolt, on described hook base, be provided with the turbine coordinating with transmission worm screw, turbine is provided with the insulated handle that drives turbine rotation.
