Abstract
The utility model discloses a simple device for drawing a window curtain comprising a set of revolving wheel system. A rotating knob can cause a window curtain or a bamboo curtain to rotate deasil and widdershins by a rope pulley to open and close the window curtain and the bamboo curtain.
Description
The utility model relates to frame for movement---the manufacturing technology of cyclic train.
The utility model " simple and easy Curtain switch " mainly is with manually control, need not any exterior power.Rotary switc turn-knob, two root window curtain backguys on the switch be through the transmission of cyclic train, forward or reverse on rope sheave, thus realize drawing back and closing of curtain.
Present employed Curtain switch mainly is to connect rope sheave by motor, by the positive and negative Kai Heguan that realizes curtain of power switch.Owing on curtain,, will in the room, pull out very long electric wire again and connect switch by adorning one group of motor and rope sheave.Therefore bothering by loading onto, and the single purchase cost is higher, so influenced its popularization and use socially.
The utility model is achieved in that
When moving turn-knob with hand-screw, turn-knob drives the empty planetary gear that is enclosed within on the H as planetary whirling arm mechanism H.The utility model uses three planetary gears with balance torsion, planetary gear is done revolution and rotation in internal gear and central gear, make central gear with times over the equidirectional rotation of the angular speed of turn-knob, because centre wheel and rope sheave are glued together, so centre wheel and rope sheave are with fast.Module of the present utility model all is 1mm, and internal gear is 75 teeth, and planetary gear, central gear respectively are 25 teeth, and the rope sheave diameter is φ 80mm.Therefore turn-knob is 1/3(i (H)/13=(Z with the ratio of rope sheave
1Z
2)/(Z
2Z
3)=(75 * 25)/(25 * 25)=3), add the rotation of pivoted arm H itself, therefore when turn-knob circles, around rope sheave has just changeed, the diameter of rope sheave is φ 80mm, so stay cord has moved 4 * 80 * π=1005mm, we draw back simultaneously or close and calculate with the curtain two sides, the mobile simultaneously 1005mm of relative direction, promptly actual mobile 2010mm altogether, like this, for one meter wide window, as long as turn round and all to open or to close with hand one.
In addition, on the rope sheave on the utility model basis, load onto a cover ratchet mechanism, so, just can control shutter and bamboo screen, and can regulate height arbitrarily.
The utility model has the advantages that, simple in structure, easy to manufacture, easy to use and should not break down.
Description of drawings:
1. base 7.12. planetary gear
2. rope sheave 8.13. nut
3. central shaft 9.14. planet wheel spindle
4. loam cake 10. central gears
5. stay cord 11. screws, packing ring
6. internal gear 15. turn-knobs
The utility model " simple and easy Curtain switch " is to twist turn-knob (15) with hand, and turn-knob drives planetary gear (7.12), and planetary gear drives centre wheel (10), will rotate with turn-knob by certain speed ratio with the rope sheave that centre wheel is joined together like this.Rope on the rope sheave is when rope sheave rotates, receive on rope sheave with rope sheave for one, emit from rope sheave for one, rope between such two pulleys will move around the other way around, as an end of an end of curtain and rope is linked up, curtain will move around with rope, thereby realizes the opening and closing of curtain.
Claims (2)
1, a simple and easy Curtain switch is characterized in that, is made up of to become base plate, shell and a cover cyclic train, and turn-knob and whirling arm mechanism are an integral body, and centre wheel and rope sheave are an integral body, and three planetary gear skies are enclosed within three axles in the pivoted arm.
2, as the described simple and easy Curtain switch of claim (1), its feature also is to load onto one group of ratchet mechanism in rope sheave, with the sagging gravity of control shutter and bamboo curtain splint.
