Abstract
A key for a switch cabinet of a high-voltage transformer substation comprises a key body and a rotary handle. Threads corresponding to a door lock of the switch cabinet are arranged in the front end of the key body. The tail end of the key body is a hexagonal prism. The specifications of the hexagonal prism correspond to those of a hexagonal connector of an electric screwdriver. The top end of the hexagonal prism is provided with a sliding mounting groove. The two sides of the inner wall of the sliding mounting groove are provided with mounting locking concave points. The rotary handle is of a strip shape. The middle of the rotary handle is provided with a sliding mounting block. The shape of the sliding mounting block corresponds to that of the sliding mounting groove. The two sides of the sliding mounting block are provided with mounting locking convex points. The mounting locking convex points are connected with each other through an elastic component.
Description
Technical field
The present invention relates to a kind of key, particularly relate to a kind of key for high voltage substation switch cubicle.
Background technology
In routine duties, switch cubicle needs frequent operation in transformer station, therefore just needs the frequent cabinet door opening and closing switch cubicle.Cabinet door lock due to switch cubicle is all adopt screw type door lock, needs to rotate 8-10 circle, existing normal key with key during unlatching, and turning moment is very little, wastes time and energy, finally have influence on the power transmission of user during the operation of therefore persistent opening and closing again.When relating in particular to the operation of bus transmission or not, relate to feeder line more, relate to user wide, can fast and reliable ground cabinet door, can effectively improve power transmission efficiency, guarantee client electricity consumption.
Summary of the invention
Technical problem underlying to be solved by this invention is to provide a kind of key, and turning moment is large, can open high voltage substation switch cubicle fast.
In order to solve above-mentioned technical problem, the invention provides a kind of key for high voltage substation switch cubicle, comprising key body and rotary handle;
The screw thread corresponding with described lock for door of switch cabinet is provided with in the front end of described key body; The tail end of described key body is hexagonal prism, and the specification of described hexagonal prism is corresponding with the hexagonal interface of electric screw driver; The top of described hexagonal prism is provided with the groove that is slidably installed, described in the be slidably installed inwall both sides of groove be provided with kayser concave point be installed;
Described rotary handle is strip, and the middle part of described rotary handle is provided with the block that is slidably installed, described in the be slidably installed shape of block corresponding with the described groove that is slidably installed; The both sides of the described block that is slidably installed are provided with installs kayser salient point, is connected between described installation kayser salient point by elastomeric element.
In a preferred embodiment: the one side of the block that is slidably installed described in described rotary handle is arranged has wavy groove, the shape of described groove and the shape of human finger adapt.
In a preferred embodiment: described in the be slidably installed cross section of groove be convex shape.
In a preferred embodiment: described elastomeric element is spring.
Compared to prior art, technical scheme of the present invention possesses following beneficial effect:
1. a kind of key for high voltage substation switch cubicle provided by the invention, has possessed the rotary handle of strip, has effectively increased moment, so make the required power applied of user diminish.
2. a kind of key for high voltage substation switch cubicle provided by the invention, key body can be separated with rotary handle, and its tail end of the key body after separation is hexagonal prism, can be arranged in electric screw driver.By the driving of electric screw driver, can quickly cabinet door be opened.
Accompanying drawing explanation
Fig. 1 is the structural representation of key body and rotary handle during the present invention preferably implements;
Fig. 2 is the internal structure schematic diagram of rotary handle in the preferred embodiment of the present invention.
Detailed description of the invention
Hereafter in conjunction with detailed description of the invention, the present invention will be further described.
With reference to figure 1, a kind of key for high voltage substation switch cubicle, comprises key body 1 and rotary handle 2;
The screw thread corresponding with described lock for door of switch cabinet is provided with in the front end 11 of described key body 1; The tail end 12 of described key body 1 is hexagonal prism, and the specification of described hexagonal prism is corresponding with the hexagonal interface of electric screw driver; The top of described hexagonal prism is provided with the groove 13 that is slidably installed, described in the be slidably installed inwall both sides of groove 13 be provided with kayser concave point 14 be installed; In the present embodiment, described in the be slidably installed cross section of groove be convex shape chute.After arranging like this, spacing by described installation kayser concave point in horizontal direction, the bottom by described convex shape groove on vertical direction is spacing.Thus make described rotary handle and key body in the vertical direction and horizontal direction all complete kayser.
Described rotary handle 2 is strip, uses the rotary handle of strip, adds the moment of handle, therefore it also reduces and rotates externally applied forces needed for key.The middle part of described rotary handle 2 is provided with the block 21 that is slidably installed, described in the be slidably installed shape of block corresponding with the described groove that is slidably installed; The described both sides being slidably installed block 21 are provided with installs kayser salient point 22, and connected by elastomeric element 23 between described installation kayser salient point 22, in the present embodiment, described elastomeric element 23 is spring.The one side of block 21 of being slidably installed described in described rotary handle 1 is arranged has wavy groove 24, and the described shape of groove 24 and the shape of human finger adapt.Meet ergonomics, increase the comfort level of user, and contribute to force.
A kind of key for high voltage substation switch cubicle that the present embodiment provides, has possessed the rotary handle 2 of strip, has effectively increased moment, so make the required power applied of user diminish.And key body 1 can be separated with rotary handle 2, its tail end of key body 1 after separation is hexagonal prism, can be arranged in electric screw driver.By the driving of electric screw driver, can quickly cabinet door be opened.
Above embodiment is only and illustrates that the principle of the invention is used, and the only embodiment of non-invention.Above-described embodiment should not be considered as limiting the scope of the invention.Those skilled in the art is reading and while understanding of aforementioned detailed description, can modify and change.Concrete protection domain should be as the criterion with claims.
