Abstract
The utility model relates to a driver for opening and closing a window curtain, which comprises a box body, a motor, a speed reducer, a first rack and a second rack and is characterized in that the shaft end of the motor arranged in the box body is fixedly connected with a power input bevel gear of the speed reducer; the power input bevel gear of the speed reducer is meshed with a power output bevel gear of the speed reducer; a power straight gear fixedly connected with the power output bevel gear of the speed reducer is meshed with the first rack and the second rack; and two ends of the box body are respectively provided with a supporting limit bracket. The first-stage speed reducer is formed by adopting the motor through the power input bevel gear and the power output bevel gear which are meshed, and the power straight gear fixedly connected with the power output bevel gear is meshed with the first rack and the second rack to drive the double sash casement window curtain, thus being simple in structure; also, the two ends of the box body are respectively provided with the supporting limit bracket, and the rigidity of the box body is good, thus having no deformation; and the driver has good opening and closing track linearity of the window curtain, stable opening and closing, long service life, automatic window opening and closing and the like.
Description
Technical field
The utility model is a kind of curtain open/close driver.
Background technology
The decelerator of existing curtain open/close driver is made up of multi-stage gear, and two tooth bars of two-way folding curtain are respectively by separately gears engaged, its complex structure, the box body volume is big, and the support stiffness of box body is poor, the folding track poor linearity of curtain, folding is not steady, and service life is low.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of simple in structure, the box body good rigidity, and the folding track linearity of curtain is good, and folding is steady, long service life, the curtain open/close driver of folding curtain automatically.
The technical scheme that solves its technical problem employing is: a kind of curtain open/close driver, it comprises box body, motor, decelerator, first tooth bar and second tooth bar, it is characterized in that: the power that is fixed with decelerator at the built-in motor shaft end of box body is imported bevel gear, and the power input bevel gear of decelerator is meshed with the power output bevel gear of decelerator, and the power spur gear that the power output bevel gear of decelerator is connected is meshed with first tooth bar and second tooth bar.Be fixed with the curtain hanging piece on first tooth bar and second tooth bar.The support limit frame all is equipped with at two ends at box body.
Curtain open/close driver of the present utility model, because the one-level decelerator that curtain open/close driver of the present utility model only adopts motor to be meshed and to form by power input bevel gear and power output bevel gear, and the power spur gear that power output bevel gear is connected is meshed with first tooth bar and second tooth bar and drives the structure of double sash casement window curtain, and it is simple in structure; Again owing to the support limit frame all is housed at the two ends of box body, the box body good rigidity, indeformable; The folding track linearity with curtain is good, and folding is steady, long service life, advantage such as folding curtain automatically.
