Description of drawings
Below, in conjunction with the accompanying drawings to the specific embodiment of the present utility model:
Fig. 1 is an embodiment schematic diagram of the present utility model;
Fig. 2 is another embodiment schematic diagram of the present utility model;
Fig. 3 is a side schematic view of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of lifting/lowering device of self-neutralization door and window, it comprises upper beam 1, underbeam 15 and some shades 17 horizontally disposed between them, that also be connected in turn with some stay cords 16, described shade 17 is a blade, also can be the cloth of folding up, upper beam 15 is a hollow material, and its inside is provided with a horizontally disposed spool 5, and described lifting/lowering device of self-neutralization door and window also comprises:
One screw rod 3, it is arranged on an end of spool 5, and one end and spool 5 are to be threaded, and the other end is connected with the screwed hole 2 of an end of upper beam 1;
One band drive unit; It comprises a motor 10, and it is installed in the motor cabinet of being located on the upper beam 19, and is positioned at spool 5 other ends;
One taper spool 8, it comprises conical section and the flat segments that fuses, the conehead of conical section and spool 5 are rigidly connected, the output shaft of flat segments and motor 10 is connected described flat segments, its junction be provided with one be located at put the beams in place in 1, and can be with a support member 4 of spool 5 move left and right, present embodiment is a bearing; The junction of described spool 5 and screw rod 3, spool 5 and taper spool 8 also is connected by other bearing 4 and supports;
In order to reduce friction, the utility model is provided with a pair of fixed pulley 7, and they are installed on the upper beam 1 of taper spool 8 both sides; After hanging down after successively by two fixed pulleys 7, the conical section larger diameter end of taper spool is being connected with a balancing weight 12 near the epimere of a stay cord 16 of motor 10 sides after smaller diameter end is reeled, U type groove is housed as the shade feeder 14 that holds shade 17 at the two ends of described underbeam 15, Fig. 3 shows that its width is slightly greater than shade 17 width.
In another embodiment of the present utility model (seeing also Fig. 2), described support member 4 is put the beams in place on 1 and is set in nut on the spool 5 for being fixed on, and is provided with thread segment on the spool 5 of relevant position, and spool 5 can utilize its screw thread to realize move left and right; It also is provided with a counterweight stay cord 11, and the upper end of this counterweight stay cord 11 is fixed on the conical section larger diameter end of taper spool 8, and conical section is provided with metallic channel with guiding counterweight stay cord 11.
Further illustrate operating principle of the present utility model by first embodiment below: still see also Fig. 1.Present embodiment is a blind that adopts the utility model device, when louver curtain is in complete hang, stay cord 16 tops have only several circles to be wound on the cylinder of spool 5 and taper spool 8, at this moment, that section stay cord 16 that connects balancing weight 12 fully is wrapped on the taper seat of taper spool 8, its free end is positioned at the minimum place of diameter, and taper spool 8 and spool 5 are in equilibrium state; When motor 10 starts, when having drawn high louver curtain, the stay cord pulling force is increasing, the stay cord of reeling on spool 5 and taper spool 8 is more and more, torque to spool 5 and taper spool 8 also increases gradually, simultaneously because the rotation of spool 5 and taper spool 8, the screw rod 3 of the other end drives them and is moved to the left, stay cord 16 number of turns of the coiling on the taper spool 8 are fewer and feweri, the diameter of free end present position is increasing, then balancing weight 12 increases synchronously by the opposing torque that stay cord 16 produces, as long as select the taper spool 8 of suitable tapering and the balancing weight 12 of suitable weight, can make spool 5 and taper spool 8 be in equilibrium state all the time.
Those of ordinary skill in the art will be appreciated that, above embodiment and principle explanation only be used for illustrating of the present utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, and all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
