Abstract

The present invention discloses a window opener which comprises a base and an upper cover, wherein a worm screw penetrates through a hole of the upper cover and is fixed between the base and the upper cover; the upper end part of the worm screw is connected with a swinging handle; a shaft pin is installed on a side base of the worm screw; a second push-pull rod which can rotate and a worm wheel are installed on the shaft pin; the worm screw and the worm wheel are engaged; the second push-pull rod is connected with a first push-pull rod through a rotary shaft and a gear on the rotary shaft; the gear is engaged with the worm wheel, and the front end of the second push-pull rod is hinged with a third push-pull rod of which the front end is provided with an installation hole. The window opener is installed on windows. If the shaking handle is shaken, the worm screw drives the gear engaged with the worm wheel through the worm wheel, the gear is used for driving the first push-pull rod to rotate, the second push-pull rod is driven to the opposite direction, namely, the first push-pull rod and the second push-pull rod simultaneously pull and push window sashes to open and close the window sashes. The window opener has the advantages of convenient use, high safety and great labor saving, and is widely suitable for the windows of various buildings.

Description

A kind of window opener

Technical field

The present invention relates to a kind of window opener, 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 object of the present invention is to provide a kind of window opener easy to use.

The present invention solves the technical scheme that its problem adopts:

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 second pull bar is hinged with the 3rd pull bar, and the front end of the 3rd pull bar has installing hole.

The invention has the beneficial effects as follows: this window opener is installed on the window frame, its first pull bar, second pull bar are 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, being first, second pull bar draws simultaneously, pushes away sash is opened and closed operation sash, 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, safe, and push away, spur simultaneously and carry out, very laborsaving.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples.

Fig. 1 is an external structure of the present invention;

Fig. 2 is the structural representation of embodiments of the invention one;

Fig. 3 is the part-structure schematic diagram of embodiments of the invention one;

Fig. 4 is the structural representation of embodiments of the invention two.

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.

Worm gear 6 and worm screw 4 engagements, second pull bar 7 is connected with first pull bar 10 by the gear 9 in rotating shaft 8 and the rotating shaft 8, gear 9 and worm gear 6 engagements, the front end that the front end of second pull bar 7 is hinged with the 3rd pull bar 11, the three pull bars 11 has the installing hole 12 that is connected with sash.

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 10 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 invention 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.
