Description
Technical field:
The utility model relates to a kind of curtain drive unit.
Background technology:
Existing roller shutter drum driving apparatus all is to handle by the pelletron (stay cord) of a ring-type, realizes opening or backrush of roller shutter.But because pelletron (stay cord) is ring-type, so pelletron (stay cord) is suspended on the fake that forms a U-shaped when aerial, when child played near the fake of U-shaped, child was suspended to neck and causes unexpected dead thing to happen occasionally in the fake.Therefore, its safety, particularly the safety for child is not enough.In order to address this problem, disclosed as patent application 200610132312.3, the inventor has designed this patent application technology and has solved the problems referred to above, this patent application technology is by box body, rotation is actively socketed on the runner in the box body, the rotating shaft that the drive reel that links together with runner rotates, the stay cord runner that rotation is actively socketed on the runner constitutes, the stay cord runner is provided with the clockwork spring groove, be provided with clockwork spring in the clockwork spring groove, one end of clockwork spring is connected on the stay cord runner, the other end and box body link together, in being actively socketed on axis hole on the runner, the rotation of stay cord runner is horizontally arranged with one or more than one ball grooves, be provided with by annular guide channel along the runner external surface, the side of annular guide channel is provided with the one or more groove that protrudes from annular guide channel, be provided with gathering sill between groove and annular guide channel, between annular guide channel and ball groove, be provided with ball, at the external surface of stay cord runner around stay cord is arranged.During work, the pulling stay cord, stay cord drives the stay cord runner and rotates, the stay cord runner drives clockwork spring simultaneously and tightens and drive ball and move along the annular guide channel of runner external surface, when ball enters the groove of annular guide channel side, then drive and rotate, thereby drive reel curtain is opened, after stay cord draws to the greatest extent, unclamp stay cord, the stay cord runner is in the effect turning down of clockwork spring screen resilience, make stay cord again rollback to the stay cord runner, during the revolution of stay cord runner, because ball can not enter the groove of annular guide channel side, therefore, ball can only move along annular guide channel, therefore,, the revolution of stay cord runner the time is that can not to drive runner rotating, like this, constantly draw, put stay cord, just drive reel curtain is opened fully.Owing to be single rope, when child played, child just can not be suspended to neck in the fake, and therefore, it is safe.But, because curtain reel revolution is with on the curtain rollback reel time, must rotate together with runner, be subjected to structural restriction, the diameter of stay cord runner is bigger, and the volume of drum driving apparatus is the restriction that is subjected to environment for use, can not be very big, cause the not very long rope of intrinsic energy of stay cord runner, and curtain reel when revolution, the influence of the resistance of the runner that can be subjected to therewith rotating has inevitably influenced its rotating smoothness.
Summary of the invention:
The drum driving apparatus that goal of the invention of the present utility model is to provide the roller shutter many ropes of a kind of stay cord runner intrinsic energy, that not influenced by the stay cord driving mechanism during revolution of curtain reel to use.
The utility model is to realize like this, by be fixed on stay cord rotating disk box on the Curtain rod, rotate the stay cord rotating disk that is wound with stay cord that is arranged in the stay cord rotating disk box, rotate the curtain reel on the spool shaft that is arranged on stay cord rotating disk box, the one-way clutch that is arranged between curtain reel and stay cord rotating disk constitutes, and is provided with the backrush spring between stay cord rotating disk and stay cord rotating disk box.The rotating shaft that arrangement of clutch is rotated by the drive curtain reel that is arranged on the curtain spool axis, the clutch slip rotary head that is positioned on the same axis of rotating shaft constitutes, the end face that rotating shaft and clutch slip rotary head join is provided with the tooth of one way engagement, stay cord rotating disk box is provided with the curtain reel and is positioned at axis hole on the same axis, clutch rotating shaft and clutch slip rotary head that rotating shaft and clutch slip rotary head join are positioned on the axis hole, the other end of clutch slip rotary head is positioned at the cover of stay cord rotating disk side, the external surface of the other end of clutch slip rotary head is provided with skewed slot, be provided with slide block in the cover of the stay cord rotating disk side of corresponding skewed slot, between clutch slip rotary head external surface and axis hole, be connected with turn.During use, stay cord down, drive the stay cord dial rotation, stay cord rotating disk band cover and is rotated together with slide block, owing to have certain stiction between turn and clutch slip rotary head external surface and axis hole, this stiction is greater than the frictional force between slide block and skewed slot, slide block is moved along skewed slot, promote clutch slip rotary head and move, its end face and the engagement of rotating shaft end face to rotating shaft, like this, clutch slip rotary head drives rotating shaft and rotates, and rotating shaft then drives the curtain reel and rotates, when unclamping stay cord, under the drive of backrush spring, stay cord rotating disk revolution is pulled back the stay cord rolling on the rope rotating disk, simultaneously, stay cord rotating disk band cover and is reversed together with slide block, slide block is oppositely moved along skewed slot, and it is moving that promotion clutch slip rotary head leaves rotating shaft, and its end face leaves the rotating shaft end face, make rotating shaft be in free state, rotating shaft is rotated along sliding together with the curtain reel.Since do not had prior art must runner, therefore, can adopt bigger backrush spring, make the stay cord rotating disk of same diameter can hide many stay cords.
Here, the turn lateral surface leans against on the shaft hole inner wall, is vertically arranged with groove at clutch slip rotary head outer wall, and a wherein end of turn is positioned at groove.During work, owing to have certain stiction between turn and axis hole, this stiction is greater than the frictional force between slide block and skewed slot, and a wherein end of turn is limited by the groove that clutch slip rotary head outer wall vertically is provided with, turn can not be rotated relative to clutch slip rotary head, but can move along the vertical non-resistance of groove, slide block is moved along skewed slot, promoting clutch slip rotary head moves to rotating shaft, its end face and the engagement of rotating shaft end face, like this, clutch slip rotary head drives rotating shaft and rotates, and rotating shaft then drives the curtain reel and rotates.When rotating in order to make clutch slip rotary head drive rotating shaft, kinetic force of friction between turn and axis hole can not increase, the spring of turn is identical around the rotation direction when driving the rotating shaft rotation with clutch slip rotary head, like this, when clutch slip rotary head drives the rotating shaft rotation, the termination of the turn by being positioned at groove drives turn and rotates, because the spring of turn is identical around the rotation direction when driving the rotating shaft rotation with clutch slip rotary head, like this, the termination of the turn of clutch slip rotary head by being positioned at groove drives turn when rotating, the diameter of turn is diminished, turn is ended the dependence upon on shaft hole inner wall, the kinetic force of friction between turn and axis hole is diminished.
The utility model compared with the prior art, owing to adopted clutch, and clutch has adopted form of structure cleverly, therefore, have the many ropes of stay cord runner intrinsic energy, the revolution of curtain reel the time is not subjected to the stay cord driving mechanism influences, advantage of simple structure.
