Interior case 3 is located in the raising middle flask 2, and itself and raising middle flask 2 relative positions are provided with vertical slide rail 30, with the two combination, and can borrow the control of transmission device 4 and upper and lower displacement, and two sides of interior case 3 inner edge rear ends are provided with tooth bar 31 (referring to Fig. 2) relatively;

Transmission device 4, be located at raising middle flask 2 dorsal parts, drive motor 40 and lifting drive motor 41 before and after it includes, front and back drive motor 40 interlocks one power transmission shaft 42, these power transmission shaft 42 2 ends are provided with tooth bar 11 engagements of travelling gear 43 and housing 1 inner edge two sides, so as to making raising middle flask 2 front and back displacements (because transmission device 4 is to be fixed in raising middle flask 2, tooth bar 11 is to be fixed in housing 1, so when 43 turns of front and back drive motor 40 transmission travelling gears, raising middle flask 2 will advance to shift out housing 1 or retreat in housing 1 and reply in the housing 1 along horizontal slide rail 10,20); These lifting drive motor 41 transmissions have a drive 44, drive 44 links one of cable wire 45 end, the end in addition of cable wire 45 is fixedly linked on the fixed bar 46 of interior case 3 bottoms, use case 3 upper and lower displacements in the order, and two sides of interior case 3 inner edge rear ends are provided with tooth bar 31 relatively, the side is provided with a driven axle 47 under the transmission device 4, two ends of this driven axle 47 are respectively equipped with driven

gear

48,48 of this driven gears and 31 engagements of aforementioned interior case 3 inner edge tooth bars, with can be when interior case 3 upper and lower displacements with interior case 3 location, and make upper and lower displacement smooth and easy (when raising middle flask 2 advance shift out housing 1 after, lifting drive motor 41 is done 44 rotations of command of execution drive, make cable wire 45 rise or descend, and then case 3 descend or rises and reply in raising middle flask 2 in making).Space below the enforcement of the utility model, housing 1 can utilize, and can't utilize cabinet lower space person than the direct descending manner of prior art, has the enhancement on the effect.

The sequence of movement of the utility model use is:

1. interior case 3 rises (referring to Fig. 2), 41 starts of lifting drive motor, and case 3 rises a little in making, with the location of disengaging with raising middle flask 2;

2. raising middle flask 2 is together with moving (referring to Fig. 3) outside the

interior case

3, and 43 turns of front and back drive motor 40 transmission travelling gears make raising middle flask 2 advance in housing 1 along

horizontal slide rails

10,20 and shift out housing 1;

3. interior case 3 descends (referring to Fig. 4), 41 starts of lifting drive motor, and case 3 drops to the precalculated position in making, the interior article of case 3 in taking in order to the user;

4. interior case 3 rises (referring to Fig. 5), after finishing using, and 41 starts of lifting drive motor, home position in raising middle flask 2 is replied in case 3 risings in making;

5. raising middle flask 2 is together with moving (referring to Fig. 6) in the

interior case

3, and 43 turns of front and back drive motor 40 transmission travelling gears make raising middle flask 2 retreat outside housing 1 along

horizontal slide rail

10,20 and move in the housing 1;

6. interior case 3 descends (referring to Fig. 7), and 41 starts of lifting drive motor descend interior case 3 a little and reply initial position location, make cable wire 45 not bear any weight.The utility model is adopted the manner of execution that rises and descend earlier, can make cable wire 45 not bear any mechanism weight when inactive state, to increase the service life.

Moreover, see also shown in Figure 8, the utility model is provided with tightening mechanism 5 in addition on transmission device 4, this tightening mechanism 5 includes the support 50 of being located at the transmission device top, support 50 belows are provided with elastic parts 51, one of support end is provided with pole 52, pole 52 is provided with a guide wheel 53 in drive 44 tops of lifting drive motor 41, the side is provided with a movable guide rod 54 and location guide 55 in addition under the guide wheel 53, and 54 of guide wheel 53 and movable guide rods also connect to one with connecting rod 56, cable wire 45 is after drive 44 makes progress solderless wrapped connection guide wheel 53, pass 55 of movable guide rod 54 and location guides again, link fixedly fixed bar 46 again, when 41 starts of lifting drive motor, the strength of cable wire stretching struts elastic parts 51, make guide wheel 53 and movable guide rod 54 to top offset, make cable wire 45 be a straight line and do upper and lower displacement action, finish and work as the upper and lower displacement action, during the 41 not starts of lifting drive motor, can guide wheel 53 and movable guide rod 54 be moved to resting position downwards by the elastic force of elastic parts 51, but press and compressing cable wire 45 under the movable guide rod 54 of mat this moment, make cable wire 45 also be the stretching state when mechanism's inactive state, this can prevent that cable wire 45 from skidding off the track of drive 44 in inactive state.

In addition, the utility model drive 44 usefulness are that the track 440 of solderless wrapped connection cable wire 45 is around forming with different inner diameters, in the present embodiment, directly less within two ends before and after the track, the centre is big (consulting Fig. 9), when drive 44 rotates, cable wire 45 transmission speeds of solderless wrapped connection on it slow-fast-slow transmission speed, if when applying to the kitchen cabinet,, use of the design of this class in this application as gear owing to taken in the article of bottle Bottle ﹠ Can jar in the cabinet, speed slow (because cable wire is wire-wrapped in little inner radius) when it starts, can avoid the interior article of cabinet to rock, and the static preceding speed that puts in place is slack-off, can avoid inertia to cause article to rock displacement.

The above person of thought, it only is the preferable possible embodiments of one of the utility model, be not in order to arrest the scope of limit the utility model, such as be familiar with this skill personage, the equivalent structure that utilization the utility model specification and claim are done changes, and ought to be included in the claim of the utility model.
