Description
Technical field
The utility model relates to a kind of window opener, and is particularly a kind of to window keying window opener easy to use.
Background technology
The sash of existing window generally be promote about adopting or with hand with sash outwards, inwardly push-and-pull and open, close, its mode of operation is tradition relatively, window and comparatively require great effort, particularly for the window of outside unlatching, the user will stretch out arm outside window and could operate the keying of sash, use dangerously, inconvenient, particularly the operation of the window that the wind surface of big, the Heavy Weight of some volumes or its installation place is bigger is just more difficult.
Summary of the invention
In order to solve the above problems, the purpose of this utility model is to provide a kind of window opener easy to use.
The technical scheme that the invention for solving the technical problem adopted is:
A kind of window opener, it is characterized in that: comprise base, loam cake, the hole that has worm screw to pass loam cake is fixed between base and the loam cake, the upper end of worm screw is connected with handle, the bottom places on the base, on the side base of worm screw pivot pin is arranged, rotating second pull bar and rotating worm gear are installed on the pivot pin, worm gear connects with worm engaging, second pull bar is equipped with first pull bar of rotating band gear by rotating shaft, gear and worm gear engagement, the front end of first pull bar is hinged with the 3rd pull bar, and the front end of the 3rd pull bar has installing hole.
The beneficial effects of the utility model are: this window opener is installed on the window frame, its first pull bar, second pull bar is connected the bottom of sash, shake handle, the gear that worm screw is engaged with by worm-gear driven, rotate by gear driven first pull bar, second pull bar is driven round about, promptly first, second pull bar draws simultaneously to sash, push away sash is opened and closed operation, because the keying that the window of these window openers is installed only need be rotated and be shaken handle and get final product, easy to use, safety, and push away, pulling is carried out simultaneously, and is very laborsaving.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an external structure of the present utility model;
Fig. 2 is the structural representation of embodiment one of the present utility model;
Fig. 3 is the part-structure schematic diagram of embodiment one of the present utility model;
Fig. 4 is the structural representation of embodiment two of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of window opener, comprise base 1, loam cake 2, the hole 20 that has worm screw 4 to pass loam cake 2 is fixed between base 1 and the loam cake 2, the upper end of worm screw 4 cooperatively interacts to install with the spline that the internal spline of handle 3 bottom handle and worm screw top are provided with and is connected, and the bottom of worm screw 4 places on the base 1; Thereby worm screw 4 is to be fixed between base 1 and the loam cake 2 by the oblique erection column 14 that is installed on the base, certainly, installing and fixing of its worm screw 4 also has alternate manner, as in the hole 20 of loam cake 2 counterbore being arranged, worm screw 4 has positive stop lug boss, and worm screw 4 is suspended in the counterbore fixing; The limited impression of placing the worm screw bottom is being arranged on the base 1, the position-limit mechanism that prevents that worm screw from outwards extracting is being arranged on loam cake 2.
The side of worm screw 4 has pivot pin 5 to be fixed on the base 1, rotating second pull bar 7 and worm gear 6 are installed on the pivot pin 5, the upper end of described worm gear 6 has baffle plate 30 affixed with the top of pivot pin 5, worm gear 6 can be clipped between the baffle plate 30 and second pull bar 7 and rotate, and second pull bar 7 is rotatable on pivot pin 5; Certainly, pivot pin 5 can be to be fixed on the loam cake 2, and other parts are done corresponding connection and be can be considered equivalent.
Between two parts of described first pull bar 10 and gear 9 is to fixedly connected by rotating shaft 8, can not rotate mutually between the three.
If the bottom of rotating shaft 8 protrudes from the bottom face of second pull bar 7, can base 1 be provided with the groove 15 of the protuberance that is used to place rotating shaft 8, this groove is curved, is convenient to moving of rotating shaft 8, because the protruding end of rotating shaft 8 is positioned in the groove 15, can reduce the thickness of window opener.
The front end of described second pull bar 7 is equipped with slide block 14, is used for being connected use with the chute of sash.
The teeth of described worm screw 4, worm gear 6, gear 9 are corresponding helical teeth, make between worm screw 4 and the window to become certain angle of inclination, and handle can not be subjected to stopping of window frame, sash, the convenient use.
For the ease of window opener is installed on the window frame, one or more installing hole 16 is arranged on the described base 1, be convenient to the user and install according to the different hole of different size Selection.
In addition, with reference to Fig. 4, can be the integrated molding structure between first pull bar 10 and the gear 9, both are by a whole block material punch forming, and by milling, draw or alternate manner being made its helical teeth teeth, the pull bar of this band gear is by in the rotating hole that is connected second pull bar 7 of rotating shaft 8, its gear 9 and worm gear 6 engagements, and this pull bar holding capacity is strong, frangibility not, safe in utilization, and because the parts minimizing, thereby the thickness of window opener can dwindle.
The use of window opener of the present utility model is that it is configured on the window frame, install by the installing hole on the base 1 16, its first pull bar 10 is fixed in an end of sash bottom, second pull bar 7 connects by the chute of slide block 8 with the sash bottom, and when shaking handle 3, worm screw 4 drives worm gear 6, gear 9 rotates, driving first pull bar 10 and 7 pairs of sash of second pull bar draws, promotes to do, can drive sash and open and close, easy to use, laborsaving.
