Abstract
A kind of sub-connecting switch of transformer fastener, relate to a kind of fastener, the upper end of connecting rod (4) is provided with handle (3), T-shape structure is formed by handle (3), connecting rod (4), be provided with in the lower end of connecting rod (4) and screw block (5), the described bottom faces screwing block (5) is provided with middle part trepanning (6), and middle part trepanning (6) both sides are respectively equipped with both sides extension slot (7); The utility model utilizes the length of connecting rod and screws middle part trepanning, the both sides extension slot of block, can make the quick degree of tightness of the butterfly screws of sub-connecting switch of transformer, and effectively overcoming prior art cannot near the drawback of shunting switch butterfly screws.
Description
[technical field]
The utility model relates to a kind of fastener, especially relates to a kind of sub-connecting switch of transformer fastener.
[background technology]
Known, in the maintenance or installation process of transformer, need to use spanner that shunting switch is carried out dismounting; By reference to the accompanying drawings 1, the high-low pressure sleeve pipe covering greatly setting at transformer is very intensive, in order to twist by hand during design, in the middle part of the holding screw installed is mostly and has, screw rod and middle part screw rod (2) both sides arrange the structure of butterfly screws handle (1), handling at every turn for butterfly screws need hand to enter between high-low pressure sleeve pipe, cautious handling, once rust is extremely had no idea substantially, conventional spanner carries out conventional dismounting to the shunting switch on transformer cannot be close.
[utility model content]
In order to overcome the deficiency in background technology, the utility model discloses a kind of sub-connecting switch of transformer fastener, the length utilizing connecting rod and the middle part trepanning, the both sides extension slot that screw block, can make the quick degree of tightness of the butterfly screws of sub-connecting switch of transformer, effectively overcoming prior art cannot near the drawback of shunting switch butterfly screws.
For realizing above-mentioned utility model object, the utility model adopts following technical scheme:
A kind of sub-connecting switch of transformer fastener, comprise handle, connecting rod and screw block, the upper end of connecting rod is provided with handle, T-shape structure is formed by handle, connecting rod, be provided with in the lower end of connecting rod and screw block, the described bottom faces screwing block is provided with middle part trepanning, and trepanning both sides, middle part are respectively equipped with both sides extension slot.
Described sub-connecting switch of transformer fastener, described in screw block outer edge surface be circular or polygonal structure.
Described sub-connecting switch of transformer fastener, the block outer edge surface that screws of described circle comprises ellipse.
Owing to adopting technical scheme as above, the utility model has following beneficial effect:
Sub-connecting switch of transformer fastener described in the utility model, sub-connecting switch of transformer fastener, the length utilizing connecting rod and the middle part trepanning screwing block, both sides extension slot are enclosed within butterfly screws, can make the quick degree of tightness of the butterfly screws of sub-connecting switch of transformer, effectively overcoming prior art cannot near the drawback of shunting switch butterfly screws; The utility model greatly reduces the time used in fastening or dismounting shunting switch butterfly screws process, improves operating efficiency.
[accompanying drawing explanation]
Fig. 1 is sub-connecting switch of transformer butterfly screws structural representation;
Fig. 2 is perspective view of the present utility model;
Fig. 3 of the present utility modelly screws block bottom surface trepanning structural representation
In figure: 1, butterfly screws handle; 2, middle part screw rod; 3, handle; 4, connecting rod; 5, block is screwed; 6, middle part trepanning; 7, both sides extension slot.
[detailed description of the invention]
Can explain the utility model in more detail by the following examples, open the purpose of this utility model is intended to protect all changes and improvements within the scope of the utility model, and the utility model is not limited to the following examples;
Sub-connecting switch of transformer fastener by reference to the accompanying drawings described in 2 or 3, comprise handle 3, connecting rod 4 and screw block 5, the upper end of connecting rod 4 is provided with handle 3, T-shape structure is formed by handle 3, connecting rod 4, being provided with outer edge surface in the lower end of connecting rod 4 is circular, oval or polygonal structure screws block 5, the described bottom faces screwing block 5 is provided with middle part trepanning 6, and middle part trepanning 6 both sides are respectively equipped with both sides extension slot 7.
Implement sub-connecting switch of transformer fastener described in the utility model, during use, first dismantle as required or fastening sub-connecting switch of transformer butterfly screws present position, the utility model is penetrated between high-low pressure sleeve pipe and " high-low pressure sleeve pipe had better not be touched by force ", be enclosed within middle part screw rod (2) and butterfly screws handle (1) fastening and dismounting can be carried out to butterfly screws by the middle part trepanning 6 and both sides extension slot 7 that screw block 5.
The non-detailed portion of the utility model is prior art.
