According to an embodiment of the present utility model, fastening have 4 with circular hole, relative 2 fastening be a pair of with circular hole, and 2 pairs of fastening lines with the circular hole centers of circle are orthogonal, along body shaft to 90 degree that stagger.
According to an embodiment of the present utility model, the nut holddown groove has 4, and 2 relative nut holddown grooves are a pair of, and the line of centres of 2 pairs of nut holddown grooves is orthogonal.
According to an embodiment of the present utility model, the nut holddown groove is divided into 4 parts with body bottom, and every a body outwardly-bent 5 degree all.
According to an embodiment of the present utility model, the external diameter of traveling nut and hold-down nut is identical, and greater than fastening internal diameter with circular hole.
According to an embodiment of the present utility model, traveling nut is removably installed on the operating grip, on hold-down nut welding and the operating grip.
Adopt the technical solution of the utility model, can effectively solve the deficiency that existing fastened tools exists, possessed following advantage:
One, the fastened tools bottom nut holddown groove of the utility model design is up-narrow and down-wide shape, can adapt to the swallow-tail form nut of different size size.
Two, the fastened tools volume of the utility model design is small and exquisite, and action bars can move around, and is adapted at small space and carries out fastening to the swallow-tail form nut.
Three, the fastened tools of the utility model design can effective fastening respirator, improves the sealed horizontal of breath device, avoids steam to enter respirator, has both reduced the consumption of drier gel, has guaranteed again the quality of transformer body transformer oil.
Four, the fastened tools of the utility model design is except can be applicable to transformer swallow-tail form nut fastening, also can be used for fastening under the narrow operating space of the similar nut of other equipment.
Description of drawings
In the utility model, identical Reference numeral represents identical feature all the time, wherein:
Fig. 1 is the structural representation of the utility model transformer breather fastened tools;
Fig. 2 is the use view of the utility model transformer breather fastened tools.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
With reference to Fig. 1, transformer breather fastened tools of the present utility model mainly is divided into body and operating grip two parts.Wherein fastened tools body 3 is whole cylindrical, opens 4 fastening circular holes 1 of using at the cylinder top, and 2 relative holes are a pair of.The line in two pairs of circular hole 1 centers of circle is orthogonal, and along Cylindorical rod to 90 degree that stagger.Bottom of cylinder is driven 4 nut holddown grooves 2, and 2 relative grooves are a pair of, and the line at the center of two pairs of holddown grooves 2 is orthogonal, after 4 nut holddown grooves 2 are divided into 4 parts with bottom of cylinder, again with about outwardly-bent 5 degree of this 4 part.Slight curving purpose is to make 2 one-tenth up-narrow and down-wide shapes of nut holddown groove, so that the swallow-tail form nut of fastening different-thickness, size.
On the other hand, as shown in Figure 1, operating grip 4 is a diameter less than the fastening iron staff with circular hole 1 internal diameter of body 3, and an end is handle traveling nut 5, and with circular hole 1, this nut is detachable during use greater than fastening for the external diameter of traveling nut 5; The other end is the hold-down nut 6 of same external diameter size, and hold-down nut 6 is welded on the operating grip 4.
With reference to Fig. 2, Figure 2 shows that an embodiment of the present utility model, introduce the using method of transformer breather fastened tools.In normally used situation, the back side and left-hand operation narrow space when respirator carries out fastening operation, original instrument can't effective fastening respirator swallow-tail form nut 7.
As shown in Figure 2, the structure of respirator comprises: the pipeline 13 that connects conservator and respirator; Flange 14 on the connecting pipe, respirator is connected with pipeline 13 by flange 14.Respirator silica gel tank 9 is used for the dress discolour silica gel, and each respirator is only installed a respirator lubricating cup 10 in the bottom, leave pore on the lubricating cup 10, links up with atmosphere.Respirator also comprises swallow-tail form nut 7 and screw rod 8.Fig. 2 illustrates each two groups of nuts 7 and screw rod 8 on two-layer silica gel tank 9 and the bottom lubricating cup 10.On actual every layer of respirator silica gel tank 9 or the lubricating cup 10 3 groups of nuts 7 and screw rod 8 being arranged, be distributed in flange 14 peripheries with 120 even angle of spending, be close to oil tank wall for unillustrated one group among Fig. 2, is a group of operating space minimum.
When using fastened tools of the present utility model, the nut holddown groove 2 with this tool body 3 bottoms is stuck on this class swallow-tail form nut 7 first.Then the size in visual execute-in-place space adopts dual mode to use this instrument.
Situation 1, operating space are too narrow and small, only allow operating grip 4 to rotate 90 degree take tool body 3 as initial point, can use according to the following steps this instrument:
Unscrewing among traveling nut 5(Fig. 2 of handle this nut removes), operating grip 4 is inserted the two relative fastening circular holes 1 of using, after driving pipe axial rotation 90 degree of body 3, extract again operating grip 4, insert another to fastening with rotating 90 degree in the circular hole 1, so circulation is until nut 7 is fastened to can't rotate again.
Unscrew the traveling nut 5 of operating grip 4, operating grip 4 is inserted the two relative fastening circular holes 1 of using, traveling nut 5 with operating grip 4 reinstalls and operating grip 4 is tightened again, then after driving pipe axial rotation 180 degree of body 3, operating grip 4 is stretched out from the fastening other end with circular hole 1, again drive pipe axial rotation 180 degree of body 3, so circulation is until nut 7 is fastened to can't rotate again.Because the traveling nut 5 at handle two ends and the external diameter of hold-down nut 6 with circular hole 1 internal diameter, can not drop out fastening with circular hole 1 greater than fastening during the handle move left and right.
Those of ordinary skill in the art will be appreciated that above specification only is one or more embodiments among the numerous embodiment of the utility model, and is not to use restriction of the present utility model.Any for the above embodiment equalization variation, modification and be equal to the technical schemes such as alternative, as long as meet connotation scope of the present utility model, all will drop in the scope that claims of the present utility model protect.
