Description

Be used for the Winder that window shade promotes operating system

Technical field

The utility model relates to the window shade field, specifically, is the Winder that is used for the window shade lifting about a kind of.

Background technology

Along with the continuous propelling of social modernization, people's living standard is more and more higher, and for example, window shade control mechanization and automation have also obtained utilization more and more widely in the daily life, thereby provide more convenience for people on the living conditions.

On the market, the structure of window shade lift control system is varied, and its parts that are used to promote are mainly moved the window shade tape by the mode of friction pulley or reel and move.Wherein, the friction pulley mode is to rely on the frictional force between friction pulley and the window shade line to drive window shade line generation motion, uses its frictional force of this mode to be difficult to control, easily produces skidding; And existing reel mode, easy overlapping card line when the window shade line twines the second layer makes the window shade line not twine uniform sequentially, will cause window shade in use operating trouble to take place easily, increases maintenance cost.

Summary of the invention

The utility model provides a kind ofly is used for the Winder that window shade promotes operating system, and one of its purpose is to solve skidding in window shade line and the roll coiling process, superimposing thread, card line problem, make wind the line uniform sequential; Two of purpose is to make window shade steadily to promote synchronously, and Winder left end or right-hand member are concordant with window shade, all can reach identical effect.

For addressing the above problem, the Winder that is used for window shade lifting operating system that the utility model provides comprises bobbin winoler seat, roll, and the bobbin winoler seat is connected with roll is coaxial, and described roll surface is an external thread structure; A guider is arranged on the described roll, and this guider is a female thread structure, and is mutually nested with the external thread structure on roll surface.

As a kind of preferred version of the present utility model, described roll left side has two incoming lines, this incoming line to be used for fixing window shade lifting line.

As a kind of preferred version of the present utility model, described guider is a guide sleeve, and this guide sleeve has two leading blocks.

As a kind of preferred version of the present utility model, described guide sleeve has two projectioies, and this projection is close to bobbin winoler seat bottom, makes guide sleeve steadily move along bobbin winoler seat bottom.Described guide sleeve has a position limit arm.

As a kind of preferred version of the present utility model, the leading block of described guide sleeve upper left side is vertically mounted on the guide sleeve, and the leading block level of lower right side is installed on the guide sleeve.

As a kind of preferred version of the present utility model, respectively there is a location pulley at described bobbin winoler seat two ends; Described location pulley is vertically mounted on the bottom of bobbin winoler seat.

As a kind of preferred version of the present utility model, the window shade of walking around leading block promotes line and both can also can connect by the location pulley of bobbin winoler seat right-hand member by the location pulley of bobbin winoler seat left end.

Technique effect of the present utility model is that because external thread structure is adopted on the roll surface, guider adopts female thread structure, mutually nested by internal and external screw thread, make window shade promote line and be close to the screw thread winding in the coiling process, it is uniform sequential to wind the line, and is difficult for overlapping; Simultaneously, window shade promotes line and is connected to the location pulley of bobbin winoler seat one end by leading block, makes window shade promote the drive of line by pulley, and window shade steadily promotes.Simultaneously, window shade line of the present utility model has two kinds of connected modes, and the location pulley that can pass through bobbin winoler seat left end or right-hand member respectively connects, thereby, this Winder has two kinds of concordant connected modes of the left and right sides with window shade, and two kinds of connected modes can both make window shade steadily promote synchronously.

Description of drawings

Below in conjunction with accompanying drawing and better embodiment the utility model is described in further detail.

6 location pulleys

The specific embodiment

Below in conjunction with preferable specific embodiment, the utility model is described in further detail.

As shown in Figure 1, the Winder that is used for window shade lifting operating system of the present utility model comprises bobbin winoler seat 5, roll 1, bobbin winoler seat 5 and 1 coaxial being connected of roll, described roll 1 surface is an external thread structure 4, the diameter of described roll 2 screw threads is more than or equal to the diameter of window shade line; A guide sleeve 3 is arranged on the described roll 1, and guide sleeve 3 is nested in move left and right on the roll 1; Two leading blocks 31 are arranged on the described guide sleeve 3, and respectively there is a location pulley 6 at described bobbin winoler seat 5 two ends.

There are two incoming lines 2 in described roll 1 left side, and this incoming line 2 is used for fixing window shade and promotes line, and window shade promotes and after line penetrates incoming line 2 the end knotting is fixed in the roll 1, promotes the line other end and passes external screw thread 4 uniform winding of incoming line 2 along roll 1.
