The left and right side of activity safety baffle plate, so that the horizontal side plate in the L-shaped bending plate can just insert the activity safety gear
In lifting breach on plate；The one end of described flap with cam and positioning hinge hole, is passed through with a positioning jointed shaft
The slideway of the be hinged left side plate for being affixed to the drawer chassis of positioning hinge hole not with the drawer chassis left and right sides
Plate is fixedly connected with the opposite sides in face；The ladder bending on the flap causes the hinge hole phase with described driver plate one end
Be hinged one corrects can contact face-to-face each other, the driver plate with another hinge hole the other end then with the slip
The vertical side plate of the L-shaped bending plate on grillage is hinged, and the slip grillage is by through two slide rails
Elongated hole, and three multi-diameter shafts being connected on the left side plate of the drawer chassis moved up and down in two slide rail elongated holes
And its plain cushion and shaft retaining ring are connected on the drawer chassis；The positioning jointed shaft on the flap is connected on the slideway
Position and the multi-diameter shaft be connected in the position on the drawer chassis left side plate and the cam on the flap
It is shaped as：When the slide plate of the drawer chassis is being shaken into realize that the grafting energization of breaker body and the drawer chassis acts
When, the slide plate promotes the cam on the flap that flap is rotated around the positioning jointed shaft, and the flap is another
End promotes one end of the driver plate, and then the other end of driver plate then promotes the slip grillage vertically upward along described two
Bar slide rail elongated hole moves, so that the level for the L-shaped bending plate being inserted into breach described in the activity safety baffle plate
The distance that side plate moves up, which reaches, makes the grafting window on the activity safety baffle plate with being connected in consolidating on the drawer chassis
The center line for determining the grafting window of safety screen coincides；In addition in the slip grillage with described two slide rail elongated holes
On flat board, also one is used to tangle the hole for stopping back-moving spring one end that the slip grillage moves up, the reset bullet
The other end of spring is connected on the drawer chassis left side plate.
The present invention has the advantages and positive effects of：The actuating mechanism of the safety screen of universal circuit breaker drawer seat is steady
It is fixed reliable, both ensured that the movement of safety screen also ensure that the opening of baffle plate interface, while institutional adjustment is spacing facilitates this dress
Put easy for installation, reliable and stable, versatile, cost is relatively low.

Embodiment
For present disclosure, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing detailed
It is described as follows：
As shown in Figure 1,2,3, 4, slider-crank mechanism is made up of flap 2, driver plate 3 and slip grillage 4.Slide grillage 4
It is made up of a L-shaped bending plate 7 and a U-board 6.Two slide rail elongated holes are carried on the side flat board 5 of U-board 6；U-board 6
The side plate riveting vertical with L-shaped bending plate 7 of opposite side flat board.It is to have one to determine on one end of one piece of strip-shaped steel plate on flap 2
Position hinge hole, a positioning jointed shaft 19 are fixed on the slideway 8 of drawer chassis side plate 1 by positioning hinge hole, and according to lifting
The cam 9 rotated around positioning jointed shaft 19 of height rotational angle design, flap 2 cause to meet the motion of two-dimensional space
The plate face of the other end of flap 2 can side plate vertical with L-shaped bending plate 7 carried out each other with the needs that plane is connected at middle part
Bending, on the hole of the two hinge holes one end that driver plate 3 can be hinged on multi-diameter shaft 13 of the other end of flap 2.Transmission
Plate 3 is the symmetrical plate of outline, and the hole of its other end connects the vertical side plate of the L-shaped bending plate 7 on slide plate 4 with jointed shaft 14
On.The two slide rail elongated holes carried on the flat board 5 on grillage 4 are slided to be used for through multi-diameter shaft 15 and the plain cushion 16 of multi-diameter shaft 15
It is fixed on shaft retaining ring 17 on drawer chassis, L-shaped bending plate 7 is fixed as one with U-board 6 with riveting nail 18.The side on flat board 5
Semicircle orifice 10 be used to hang return spring 20, the other end for hanging return spring 20 is fixed on drawer chassis side plate 1.Slide the L-shaped of grillage 4
The part of horizontal grillage 11 of bending plate 7 is for insertion into the lifting breach on activity safety baffle plate 21, with activity safety baffle plate
21 with slide grillage 4 move up when be also lifted up.The transmission of right crank slide block mechanism on right left drawer chassis side plate
Mechanism is identical with the transmission mechanism mirror image of left crank slide block mechanism.
The slide plate 23 for being placed with the drawer chassis of omnipotent breaker body is shaken into realize that grafting of the body with taking out seat is led to
When electric, when the slide plate 23 of drawer chassis moves forward, slide plate is promoted towards the upper angle of activity safety baffle plate one end and is hinged on drawer chassis
Flap 2 rotate and overcome the counter-force of reset tension spring 20, the passing power of flap 2 promote driver plate 3 rotate, driver plate 3 promotes again
Grillage 4 is slided, so slip grillage 4, which is changed into the rotation of flap 2, vertically moves, and slides grillage 4 and is carried upwards along slide rail elongated hole
Rise activity safety baffle plate 21 to rise, being finally reached activity safety baffle plate 21, staggeredly grafting window overlaps one with fixed safety screen 22
Cause, slider-crank mechanism of the invention does not reoperate, and drawer chassis continues the final copper for realizing breaker body and drawer chassis of action
Busbar grafting, so as to complete to plug together connection between drawer chassis copper bus-bar and breaker body.When drawer chassis slide plate 23 reversely from
When being plugged into isolated location action, the pulling slip grillage 4 of reset tension spring 20 does the final drawer chassis of homing action vertically downward
Slide plate 9 returns to original position, and all devices of safety screen also all reset.
