Abstract

The utility model discloses a rack type window opening device, comprising a shell, a spur rack which is connected with the window sash and a driving component. One end of the shell is opened with a cut. The spur rack is movably arranged inside the shell and capable of extending out of the shell cut. The driving component is provided with a driving gear, and the gear is engaged with the spur rack. The driving component is controlled by a control circuit to transmit power and directly drive the gear into bidirectional rotation, and the spur gear is correspondingly driven to extend, then the opening and closing of the window cash are achieved. The utility model has a rather simple structure, thereby correspondingly reducing production cost, with more reliable capability for using and low failure rate.

Description

A kind of rack-and-pinion window opener
Technical field
The utility model relates to a kind of electric window-opening device.
Background technology
Window opener has appearred in convenience and safety for window uses on the market, generally have manually and electronic two kinds, in general can only use the electric window-opening device under the convenience of using and some occasion.Existing electric window-opening device generally all is to adopt chain structure, mainly by motor through the train of reduction gears rear driving wheel, make chain push or close sash open, but this complex structure, the manufacturing cost height.
Summary of the invention
The purpose of this utility model is to provide a kind of window opener simple in structure, and use is more reliable, and reduces manufacturing cost.
The utility model is to realize above-mentioned purpose like this:
A kind of rack-and-pinion window opener is characterized in that comprising housing, spur rack that is connected with sash and driver part, described housing one end opening, being installed in the housing of spur rack activity also can be stretched out from shell nozzle, and described driver part is provided with driven wheel, this gear and spur rack engagement.
Described driver part also comprises motor and train of reduction gears, the input gears engaged of the output shaft of motor and train of reduction gears, and the output gear of train of reduction gears links to each other with driven wheel.
Be useful on window opener is installed on installation sign indicating number on the window frame, it connects in housing by rotating shaft.
Be useful on the connection sign indicating number that spur rack is connected with sash, the one end is fixedlyed connected with sash, and the other end links to each other with spur rack by another rotating shaft.
The beneficial effects of the utility model are: directly drive driven wheel by control circuit control driver part outputting power and produce rotating, the flexible opening and closing that can realize sash of corresponding drive spur rack, structure is quite simple, therefore can correspondingly reduce manufacturing cost, and use is more reliable, and fault rate is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a broken away view of the present utility model;
Fig. 2 is the user mode figure after sash is closed;
Fig. 3 is the user mode figure after sash is opened.
The specific embodiment
With reference to Fig. 1, a kind of rack-and-pinion window opener, comprise housing 1, spur rack 2 that is connected with sash 4 and driver part 3, described housing 1 one end openings, being installed in the housing 1 of spur rack 2 activities also can be stretched out from housing 1 opening, and described driver part 3 is provided with driven wheel 31, this gear 31 and spur rack 2 engagements.Produce rotating by the direct driven wheel 31 of control circuit control driver part 3 outputting powers, the corresponding drive spur rack 2 flexible opening and closing that can realize sash 4, structure is quite simple, therefore can correspondingly reduce manufacturing cost, and use is more reliable, and fault rate is low.
Wherein, described driver part 3 also comprises motor 32 and train of reduction gears 33, the input gears engaged of the output shaft of motor 32 and train of reduction gears 33, and the output gear of train of reduction gears 33 links to each other with driven wheel 31.Can slow down by train of reduction gears 33 and to adjust the speed of sash 4 switches, also can increase driving moment simultaneously.
With reference to Fig. 2 and Fig. 3, installation for the ease of window opener, also include and sign indicating number 6 is installed and is connected sign indicating number 7, be respectively applied for and window opener be installed on window frame 5 and spur rack 2 is installed on the sash 4, because sash 4 position between window frame 5, sash 4 and window opener relation in the process of switch need change, therefore sign indicating number 6 is installed and is connected yards 7 and all be connected with housing 1 and spur rack 2 by rotating shaft respectively.Along with sash 4 motions, window opener can rotate respectively around the shaft to adapt to the variation of position.
