Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of high-voltage feedback power latching device for switch of the utility model, as shown in Figure 1, including blocking device body 1, locking dress
It puts body 1 to be made of L-shaped portion 10 and 11 two parts of hollow circular cylinder portion, holding section 9, hollow circular cylinder is provided in L-shaped portion 10
Bolt A2 and axis pin 3 in portion 11 are housed, padlock 4 is connected on axis pin 3.
In the high-voltage feedback power latching device for switch of the utility model：As shown in Figure 1, Figure 2, Figure 3 and Figure 4, hollow circular cylinder
Hole A5 and hole D8 are respectively arranged in portion 11, hole B6 is provided on bolt A2, hole C7 is provided on axis pin 3；The screw thread of bolt A2
End passes through hole D8 by the end face in hollow circular cylinder portion 11；Axis pin 3 also cross hole A5 and hole B6, with blocking device body 1 and
The screw cap end connection of bolt A2；The end cap diameter of axis pin 3 is more than the aperture of hole A5；Padlock 4 is connected through hole C7 with axis pin 3.
The effect difference of critical piece is as follows in a kind of high-voltage feedback power latching device for switch of the utility model：
Bolt A2：Screw cap end is fixed by axis pin 3 and padlock 4, and the bolt B that the end of thread is carried with high-voltage feedback power switch passes through
It is threadedly coupled, then is fixed high-voltage feedback power switch handle by bolt B；
Axis pin 3：End cap diameter is more than the aperture of hole A5, and other end connection padlock 4 makes axis pin 3 be fixed on blocking device sheet
In body 1.
Holding section 9：Blocking device is sleeved at the internal thread groove of bolt B by holding section 9, further fixing bolt B.
The high-voltage feedback power latching device for switch of the utility model, the course of work are as follows：
Before high voltage electric equipment maintenance is carried out, high-voltage feedback power switch handle need to be beaten in the position cut off the power, and protected
It is fixed to demonstrate,prove switch handle.Bolt B is carried on high-voltage feedback power switch, has internal thread groove in bolt B, first by one end of bolt B
