Embodiment
As shown in the figure, a kind of draw out switchgear cabinet drawer type propelling device, it has fixed mount, fixed mount is installed one and advance spiral 3, this propelling spiral 3 have many spiral grooves that can be engaged with the keeper on drawer-bottom board, described propelling spiral 3 has the driving shaft stretching out fixed mount front, described driving shaft has for connecting the interface driving spanner;
Described driving shaft is provided with sleeve gear 1 regularly, sleeve gear 1 is engaged with locating wheel 2, described locating wheel has front end face and rear end face, the neighboring of the rear end face of locating wheel arranges multiple drawer advanced positions location notch, fixed mount is provided with a locating shaft 21, locating shaft has the retainer spring that locating shaft can be biased toward locating wheel, locating shaft can coordinate with described drawer advanced positions location notch, for positioning when drawer advances to diverse location; Fixedly mount a position indicating dial 5 in the central area of the front end face of locating wheel, described position indicating dial 5 is used to indicate the advanced positions of drawer; The leading flank of locating wheel arranges a radial lock slots 19;
Fixed mount comprises bolt drive system fixed head, this bolt drive system fixed head is provided with bolt drive system, this bolt drive system fixed head has leading flank and trailing flank, one end of pull bar 8 is hinged on the leading flank of drive system fixed head, hinged in one end of the middle part of pull bar 8 and bolt 9, the other end of pull bar 8 is fixedly connected with one end of connecting pin, bolt drive system fixed head offers penetrating arc groove, connecting pin passes this arc groove and the other end of described connecting pin is fixedly connected with one end of fork arm 7, the other end of described fork arm 7 has elongate slot, one end of hinged driving rocking arm 6 on the trailing flank of drive system fixed head, at the jointed shaft place of described driving rocking arm 6, there is driving interface, driving the other end of rocking arm 6, there is drive pin, described drive pin can be slidably matched with the described elongate slot of described fork arm 7, the rotation of rocking arm 6 can drive fork arm 7, connecting pin, pull bar 8 to rotate together thus, and connecting pin can slide in arc groove, the leading flank of described fixed head also arranges spacing hole, bolt 9 is through this spacing hole, and bolt 9 and spacing hole are a kind of matched in clearance, this matched in clearance can make bolt 9, under the effect of rotating produced thrust or pulling force by pull bar 8, axial relative motion occur in spacing hole, the other end of bolt 9 can coordinate with described lock slots 19 when described lock slots 19 moves to correct position, thus can lock in place wheel rotation.
Valuably, the quantity of described drawer advanced positions location notch is three.
Valuably, after locating wheel is located by locating shaft, lock slots moves to the correct position that can coordinate with the other end of described bolt 9.
When drawer and cabinet released state, in the separation point position location notch that the three position locating shafts 21 of positioning ejection reed one end embed locating wheel 2 143, when operating grip insertion sleeve gear 1 rotates clockwise, drive advance spiral 3 now the three position locating shafts 21 of positioning ejection reed one end exit separation point position location notch 143 and collide auxiliary switch and carry out disconnection action, advance spiral 3 to produce with keeper to be engaged, drives drawer moves in cabinet simultaneously.
When entering test position, hear " gear " sound, the three position locating shafts 21 of positioning ejection reed one end embed in the test position location notch 142 of locating wheel 2, realize test position location, simultaneously because three position locating shaft 21 positions of positioning ejection reed one end are replied, auxiliary switch is made to carry out closed action energising.Now due to the restriction of locating wheel 2, main switch can not be closed a floodgate, and drawer can not be extracted out, and position indicator 5 shows test position.
Again during rotary axle box gear 1, first the three position locating shafts 21 of positioning ejection reed one end exit test position location notch 142, and auxiliary switch carries out disconnection action, advance spiral 3 drives drawer to move in cabinet.Locating wheel 2 rotates simultaneously.When arriving link position, hear " gear " sound, the three position locating shafts 21 of positioning ejection reed one end embed in link position location notch 141, realize link position location.Simultaneously because three position locating shaft 21 positions of positioning ejection reed one end are replied, auxiliary switch is made to carry out closed action energising; Now just aim at bolt 9 by the rotation combined floodgate location notch 19 of locating wheel 2, therefore main switch can close a floodgate, and after main switch closes a floodgate, mechanism can not rotate, and now position indicator 5 shows link position, finally be rotated counterclockwise the accessories apparatus on cabinet panel, cover the handle hole of operating mechanism.
By with upper type, those skilled in the art can make various change according to mode of operation within the scope of the invention.
