[specific embodiment]

The utility model will be further described below in conjunction with accompanying drawing.

Extremely shown in Figure 5 as Fig. 1, the utility model drawout cubicle lowering or hoisting gear is on structural design, mainly be that the drawout cubicle 10 and the cabinet plate 20 of its end face are done the separate type design, reserve a tank 11 in drawout cubicle 10 both sides respectively and establish one group of cover receipts formula adjustment arm 1 for organizing respectively, laterally be provided with the groove 12 that always connects both sides tank 11 again in drawout cubicle 10 end faces, be horizontally set with a trace 2 in this groove 12 and obtain the continuous action relation that arm 1 is adjusted in both sides to insert knot;

This adjustment arm 1 mainly be by a matrix 30 with organize formula expansion plate 40 cover groups in the lump and form, wherein:

This matrix 30 is a plate body punch forming, and utilize bolt 3 to be locked in drawout cubicle 10 both sides tanks 11 positions admittedly, fold the top board 31 that forms a tool limitting casing 32 in matrix 30 tops, and must be matched with drawout cubicle 10 end faces locks and establish a cresting plate 13 to increase the aesthetic property of assembly, matrix 20 nearly hypomeres are a pair of frame gripping arm 33 of punch forming then, by utilizing 33 pairs of expansion plates of this limitting casing 32 and frame gripping arm 30 to form the spacing effect of holding of leading, be provided with a ratchet-gear wheel 34 in middle part, matrix 30 top in addition, and be provided with a perforation 35 with respect to ratchet-gear wheel 34 shaft core positions, the axle center of tying in two ratchet-gear wheels 34 is inserted in the perforation 35 that above-mentioned trace 2 is adjusted arm 1 matrix 30 by both sides, use the continuous action relation of obtaining two ratchet-gear wheels 34, simultaneously, the middle part of the arm of side adjustment therein 1 matrix 30 is provided with together vertically guide groove 36, this vertical guide groove 36 has laterally extended multistage locating groove 37, and these locating grooves 37 can be in order to regulate the relativeness of location expansion plate 40 and matrix 30;

This expansion plate 40 is by two microscler plates 41,42 and set up jointly, its top is respectively by one group of fixed head 21 and cabinet plate 20 rank knots, the place is provided with a vertical toothrow sheet 43 in the middle of its inboard plate 41 medial surfaces depart from, and make this toothrow sheet 43 and the ratchet-gear wheel 34 of aforementioned substrates 30 obtain the relation of being engaged and linked, and therein a side adjust arm 1 expansion plate 40 in, outside plate 41,42 are folded with a location connecting rod 44, this positioning linkage rod 44 is hubbed at the control 45 of pulling at plate 41 tops, the outside and is pulled the control interlock, the lower end of positioning linkage rod 44 then sees through inboard plate 42 default hole slots 421 and ties with the spacer 46 eccentric pivots of being located at medial surface, this spacer 46 is by a pin 4 and inboard plate 42 pivots knot location, and lead for spacers 46 1 side lugs 5 by inboard plate 42 prefabricated arc guide grooves 422 and to hold, be provided with a snib 6 in spacer 46 movable ends again, obtain card fastening position in order to cooperate with the locating groove 37 of aforementioned substrates 30, and establish a back-moving spring 48 with 47 groups on a bolt in expansion plate 40 inboard plates 42 precalculated positions, these back-moving spring 48 1 end bars support and to terminate in the prefabricated card lug 423 of inboard plate 42, other end bar is then inserted and is butted on spacer 46 1 side lugs 5 places, the utility model drawout cubicle lowering or hoisting gear is broken away from from positioning states by these positioning linkage rod 44 drawing spacers 46 pivots, and makes spacer 46 reply card fastening position by back-moving spring 48.

As shown in Figure 6 and Figure 7, when the utility model drawout cubicle lowering or hoisting gear is operated the height lift adjustment of cabinet plate 20 when desire, need to adjust the arm 1 expansion plate 40 outside plates 41 default controls 45 of pulling and pull upwards interlock of control interlock positioning linkage rod 44 by a side wherein, can impel spacer 46 led by arc guide groove 422 spacing of inboard plate 42 to hold and produce beat, make the snib 6 of spacer 46 movable ends break away from the locating groove 37 that matrix 30 vertical guide grooves 36 are extended, discharge the positioning relation of expansion plate 40 and matrix 30, make it be operated the lifting slippage of expansion plate 40, thereby carry out the high and low position adjustment of cabinet plate 20, and when expansion plate 40 up or down is shifted, vertical toothrow sheet 43 that these inboard plate 42 1 sides set firmly makes the ratchet-gear wheel 34 of engaged transmission matrix 30 produce rotation, and interleave the interlock effect that the trace 2 of knot is given via two ratchet-gear wheels 34 that arm 1 matrix 30 is adjusted in both sides, drive ratchet-gear wheel 34 rotations of other side, and then mesh its relative toothrow sheet 43 and produce synchronization lifting together with its expansion plate 40, rank is organized in the cabinet plate 20 on both sides expansion plate 40 tops, be able to lean to one side under the action that expansion plate 40 synchronization liftings adjust two, form lift in height adjustment very stably, and at released strip this pull control 45 pull the control strength after, the response force that can utilize back-moving spring 48 to accumulate pushes back spacer 46, the snib 6 of spacer 46 movable ends is snapped in the default locating groove 37 of matrix 30 once more, reply matrix 30 and locate, make the height state of cabinet plate 20 be obtained firmly to keep with the relativeness of expansion plate 40.By above explanation, the utility model is on cabinet plate 20 Height Adjustment of drawout cubicle 10 as can be known, design to innovation the adjustment arm 1 that forms by matrix 30 and expansion plate 40 cover groups, cooperate the design of a trace 2 interlock both sides with toothrow sheet 43 engagement ratchet-gear wheels 34, make it only need to do synchronous lift adjustment by the one-sided expansion plate 40 that can impel both sides to adjust arm 1 of controlling, make the high and low position adjustment of cabinet plate 20 can obtain to implement very reposefully, have multistage simultaneously and adjust positioning function, make the height of cabinet plate 20 be complied with best adjustment of actual user mode work, and keep the very firm location of acquisition.
