Background technology
Current safe distance and the insulating requirements when meeting earth connection operation, the insulating bar of earth connection is generally long, and in the actual production process of power station, earth connection is mainly used in Repair of Transformer or various busbar overhaul, the high-pressure side of dry-type transformer is generally cable and connects, low-pressure side is copper bar, and the bus of station service electrical system all adopts copper bar to form, be limited to the internal structure of dry-type transformer, busbar type of attachment and space size, existing earth connection often can exist and articulate inconvenience in actual use, miscellaneous equipment disturbs insulating bar and affects the problem hanging of hook, its main cause is that clamp for ground wire is fixedly connected with insulating bar, its relative position can not arbitrarily regulate.
Utility model content
The technical problems to be solved in the utility model is just: the technical problem existing for prior art, the utility model provide a kind of simple in structure, easy and simple to handle, hook is flexibly connected with insulating bar and have auto-lock function, can meet the hook type earth connection that different angles and different azimuth hang requirement.
For solving the problems of the technologies described above, the technical scheme the utility model proposes is:
A kind of hook type earth connection, comprise hook and insulating bar, one end of described insulating bar is provided with insulation handle, the other end is provided with Connection Block, one end of described hook is provided with ratchet, and described ratchet is rotatably installed on described Connection Block by a bearing pin, and a side of described Connection Block is hinged with fork, one end of described fork is provided with the detent matching with described ratchet, is provided with and orders about the spring that detent compresses ratchet between described fork and Connection Block.
Further improvement as technique scheme:
The middle part of described fork is hinged on described Connection Block.
Described spring is Compress Spring, and one end of described Compress Spring is connected with fork one end away from described detent, and the other end is connected with described Connection Block.
Described insulating bar is fiberglass epoxy resins insulation bar.
Compared with prior art, the utility model has the advantage of:
Hook type earth connection of the present utility model, is arranged to the connected mode of insulating bar and hook movable, hang requirement, thereby applicable different places is used in the time of can meeting different angles and different azimuth; On Connection Block, be hinged with in addition fork, one end of fork is provided with detent, and detent is the ratchet on compression hook under the ordering about of spring, thereby guarantees that hook can not rotate when normal hook, convenient and practical.

Number in the figure represents: 1, insulating bar; 11, handle; 12, Connection Block; 2, hook; 21, ratchet; 3, bearing pin; 4, fork; 41, detent; 42, spring.
Embodiment
Below in conjunction with Figure of description and specific embodiment, the utility model is further described.
Fig. 1 to Fig. 5 shows the embodiment of a kind of hook type earth connection of the present utility model, this hook type earth connection, comprise hook 2 and insulating bar 1, one end of insulating bar 1 is provided with insulation handle 11, the other end is provided with Connection Block 12, one end of hook 2 is provided with ratchet 21, ratchet 21 is rotatably installed on Connection Block 12 by a bearing pin 3, on hook 2, be also connected with earth terminal (not shown), one side of Connection Block 12 is hinged with fork 4, one end of fork 4 is provided with the detent 41 matching with ratchet 21, between fork 4 and Connection Block 12, be provided with and order about the spring 42 that detent 41 compresses ratchet 21.Hook type earth connection of the present utility model, is arranged to insulating bar 1 and the connected mode of hook 2 movable, hang requirement, thereby applicable different places is used in the time of can meeting different angles and different azimuth; During use, detent 41 and ratchet 21 are thrown off, thereby free rotational hook 2 is adjusted angle, while articulating, spring 42 orders about detent 41 and compresses ratchet 21, be that detent 41 snaps in the self-locking that realizes ratchet 21 in the teeth groove of ratchet 21, thereby hook 2 is articulating Shi Buhui rotation, and it is easy to operate, simple in structure.
In the present embodiment, the middle part of fork 4 is hinged on Connection Block 12, and spring 42 adopts Compress Spring, one end of Compress Spring is connected with fork 4 one end away from detent 41, the other end is connected with Connection Block 12, during use, Compress Spring is in compressive state, one end that fork 4 connects Compress Springs can be under the elastic force of Compress Spring to the movement outside of Connection Block 12, thereby the detent 41 that impels fork 4 other ends snaps in the braking that realizes ratchet 21 in the teeth groove of ratchet 21, when needs unclamp detent 41, one end of Compress Spring is set by draft link 4, the other end is outwards motion, detent 41 is thrown off with ratchet 21, realize freely rotating of ratchet 21.In other embodiments, spring 42 is extension spring, between detent 41 and pin joint one section of one end of extension spring and fork 4 is connected, the other end is connected with Connection Block 12, during normal condition, extension spring is in extended state, fork 4 one end that connect extension spring can be under the pulling force of extension spring to the interior lateral movement of Connection Block 12, thereby detent 41 is snapped in to the braking that realizes ratchet 21 in the teeth groove of ratchet 21, when needs unclamp detent 41, press draft link 4 away from one end of detent 41, detent 41 is thrown off with ratchet 21, realize freely rotating of ratchet 21.
In the present embodiment, insulating bar 1 is fiberglass epoxy resins insulation bar, good insulating, the fail safe of raising operation.
Although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model.Any those of ordinary skill in the art, in the situation that not departing from technical solutions of the utility model scope, all can utilize the technology contents of above-mentioned announcement to make many possible changes and modification to technical solutions of the utility model, or be revised as the equivalent embodiment of equivalent variations.Therefore, every content that does not depart from technical solutions of the utility model,, all should drop in the scope of technical solutions of the utility model protection any simple modification made for any of the above embodiments, equivalent variations and modification according to the utility model technical spirit.
