Embodiment
Please refer to Fig. 1, Fig. 2 and Fig. 3, a kind of switchgear door hoisting mechanism, it connects the cabinet doorframe and the sliding door 10 of this switchgear, and this mechanism comprises two linkage units 20 and a lift unit 30.
This linkage unit 20 comprises that one rotates guide finger 21, cabinet installation hinge 22 and two sliding doors installation hinge 23.This cabinet is installed hinge 22 affixed these doorframe first sides, and this sliding door is installed hinge 23 affixed these sliding door 10 first sides.This sliding door is installed the slip perforation that offers a longitudinal axis on the hinge 23, and this rotation guide finger can rotate, slide and pass this slip perforation, and affixed respectively this two sliding door in these two ends of passing is installed hinge.Thereby make: formation can vertically slide up and down the annexation of rotating relative to longitudinal axis with energy between this sliding door 10 and this doorframe.
This lift unit 30 comprises that a door lock handle 31, a fixed lever, drive handle connecting lever 32, a connecting rod 33, supports skid plate 34, a cabinet fulcrum hinge 35 and a spacer pin 36.
This door lock handle 31 can rotate the front that is arranged on this sliding door 10, this drives handle connecting lever 32 can rotate the back side that is arranged on this sliding door 10, and, this fixed lever rotates and wears this sliding door 10 and affixed this door lock handle 31 and this and drive handle connecting lever 32, can rotate this simultaneously and drives handle connecting lever 32 so that rotate this door lock handle 31.
The upper end of this connecting rod 33 is rotationally connected, and this drives handle connecting lever 32, a be rotationally connected end of this support skid plate 34 of the lower end of this connecting rod 33, this support skid plate 34 can connect this cabinet fulcrum hinge 35 rotationally, and this rotates to rotate around longitudinal axis, and, these cabinet fulcrum hinge 35 affixed these doorframes.
The back side that this spacer pin 36 is installed in the back side of this sliding door 10 and protrudes this sliding door 10.This side of driving handle connecting lever 32 has a position of the fulcrum 322, and this position of the fulcrum 322 is selected against this spacer pin 36 or away from this spacer pin 36.
This cabinet is installed hinge 22 and this cabinet fulcrum hinge 35 is installed on the switch cabinet body by bolt; By this rotation guide finger 21 and this sliding door 10 sliding doors are installed again and hinges 23 are installed sliding door 10 is connected with cabinet, slide up and down so that sliding door 10 can be done on cabinet by rotation guide finger 21, can be around the longitudinal axis switch cabinet body that is rotationally connected.
Clockwise rotate this door lock handle 31 of rotation, drive this and drive handle connecting lever 32 and clockwise rotate, promote this support skid plate 34 by this connecting rod 33 and move down (operation principle of driving the handle slide block mechanism that this has used normal quadric chain).It moves down principle: since this support skid plate 34 relatively this cabinet fulcrum hinge 35 move up and down, this cabinet fulcrum hinge 35 is fixed on the cabinet again, this support skid plate 34 can't move, therefore under reaction force acts, this sliding door 10 just moves upward, and this sliding door 10 is promoted.After rotating the dead point, this moment, spacer pin 36 stopped that driving handle connecting lever 32 is rotated further, and also was that this position of the fulcrum 322 is resisted against spacer pin 36, and entire mechanism is in position of the fulcrum, can be to lower slider, as shown in Figure 1 so can make sliding door 10 be in a high position.This dead point can refer to that the rotation center of circle, two ends of the connecting lever 32 rotation centers of circle, connecting rod is positioned on the same straight line, and this connecting lever and shaft portion overlap.This mechanism can guarantee the flexible lifting of switchgear door, can not glide automatically when guaranteeing the Men Zaigao point.
Rotate counterclockwise rotation door lock handle 31, make this position of the fulcrum 322 away from this spacer pin 36, this sliding door 10 is just moved downward, process is with reference to lifting process.After rotating the dead point, under action of gravity, sliding door 10 moves down, and last cabinet is installed plane of hinge 22 and the planes overlapping that sliding door is installed hinge 23, and sliding door 10 stops gliding, and is stabilized in the lower end under action of gravity, as shown in Figure 3.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
