[embodiment]

Embodiment one

Fig. 3 to Fig. 7 shows a kind of embodiment of the present utility model.

As Fig. 3, shown in Figure 5, this instrument transformer erecting device comprises fixed head 10, connector and knuckle spare.Fixed head 10 is a square plate, and the lower end is provided with screw hole 11; Connector comprises riser 21 and transverse slat 22, and riser 21 vertically is connected with transverse slat 22, and integral body is " L " type, and on fixed head 10, transverse slat 22 length are corresponding with instrument transformer 200 thickness d by screw for riser 21; Knuckle spare comprises first flap 31, second flap 32 and the 3rd flap 33, the first flaps 31, second flap 32 and the 3rd flap 33 vertical connection in twos, and integral body is " Z " font; Two sides of transverse slat 22 are upwards dug and are formed reinforcement 221, have strengthening action; In conjunction with Fig. 4, first flap, 31 length are corresponding with instrument transformer 200 height h, and second flap, 32 length are corresponding with instrument transformer 200 thickness d; The 3rd flap 33 is provided with screw hole 34 and suitable with the screw hole 11 of fixed head 10 lower ends; The free end of first flap 31 is a bent angle 311, offer the slotted hole suitable on transverse slat 22 free ends with bent angle 311, correspondingly form pivot 222 (for strip), first flap 31 is articulated on the transverse slat 22 behind the slotted hole that bent angle 311 inserts on the transverse slat 22, and first flap 31 can pivot around pivot 222; Two sides of second flap 32 are upwards dug and are formed reinforcement 321, have strengthening action.

When instrument transformer 200 is installed, as shown in Figure 5, pastes mutually and fix on it fixed head 10 and copper bar 100 are parallel earlier, then with the slotted hole on the bent angle 311 insertion transverse slats 22; As shown in Figure 6, instrument transformer 200 is inserted in copper bar 100 and it is abutted on the transverse slat 22, first flap 31 can pivot around pivot 222 and be fitted on the fixed head 10 until the 3rd flap 33, the shape at the position that space that this moment, fixed head 10, connector and knuckle spare surrounded and instrument transformer 200 are fixed adapts, first flap 31, second flap 32 are fitted in the respective surfaces of instrument transformer 200 respectively, and the screw hole 34 on the 3rd flap 33 aligns with screw hole 11 on the fixed head 10, and screw 40 passes screw hole 34, screw hole 11 lockings.As shown in Figure 7, one side being enclosed in the fixture of instrument transformer 200, connector and knuckle spare are " several " word shape together.Connector and knuckle spare are when being locked in fixed head 10 with screw 40, can screw hole also be set in the relevant position of copper bar 100, screw 40 can extend 100 li of copper bars and copper bar 100 is locked together like this, fixture, instrument transformer 200, copper bar 100 three's one integrated mass, there is not relative motion, even copper bar 100 vibration damage, instrument transformer 200 can not come off yet.

When instrument transformer 200 needs repairing, two screws 40 on the knuckle spare of only need dismantling, instrument transformer 200 will slide freely; Screw 40 can adopt the hexagonal screw assemblies, and dismounting is easy to, and is applicable to a lot of spanners, just can change as long as reserve the revolution space distance of spanner thickness and knuckle spare.

Embodiment two

The difference of present embodiment and execution mode one is: fixed head 10 is not set in the present embodiment fixture.When instrument transformer 200 was installed, riser 21 directly was fixed on the copper bar 100, and the 3rd flap 33 also directly is fixed on the copper bar 100.

In above execution mode, it is square that instrument transformer is that annular and cross section are, so the plate in connector and the knuckle spare is the flat sided straight plate.If the cross section of instrument transformer is circular or other shape, connector and knuckle spare made with the instrument transformer shape that the position adapts that is fixed gets final product.

During concrete enforcement, riser 21 and the 3rd flap 33 the mode on fixed head 10 or the copper bar 100 of being fixed on also can adopt the alternate manner of screw outside fastening.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
