The specific embodiment
With reference to Fig. 1, Fig. 2, the structural representation of embodiments of the invention one, its structure is as follows: window opener, comprise base 1, loam cake 2, have on the base 1 window opener is fixed on installing hole 30 on the window frame, the hole 6 that has worm screw 10 to pass loam cake 2 is fixed between base 1 and the loam cake 2, the upper end of worm screw 10 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, the bottom of worm screw 10 places on the base 1, thereby worm screw 10 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 10 also has alternate manner, as in the hole 6 of loam cake 2 counterbore being arranged, worm screw 10 has positive stop lug boss, and worm screw 10 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.
12 engagements of the teeth 11 of worm gear 5 and the teeth of worm screw 10 connect, and both teeth 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, makes things convenient for use.
In Fig. 1, Fig. 2, pull bar 4 is one, and by worm gear 5 rotating sides that are fixed on worm screw 10, pull bar 4 is one section, and front end has installing hole 7, is fixed with slide block 8 in the installing hole 7, is used for being connected use with the chute of sash.
During use, window opener is installed on the window frame by the installing hole on the base 30, and its pull bar 4 connects with the chute of sash by slide block 8, when shaking handle 3, worm screw 10 drives worm gear 5 and rotates, and drives pull bar 4 and 13 rotates around the shaft, can drive sash and open and close, easy to use.
With reference to Fig. 3, Fig. 4, the structure of its base 1, loam cake 2, worm screw 10, worm gear 5 is identical with the structure of embodiment one, its difference is: the bar of described pull bar 4 partly is first section 4 ' and second section 4 "; be articulated and connected between the two-section; the front end of pull bar 4 have and sash between fixing installing hole 7, this window opener is suitable on the less window of volume.
In the pull bar 4 of band worm gear 5, between worm gear 5 and the pull bar 4 can be to be fixed by connected modes such as welding, rivet, spline are connected by two independent parts, certainly, for the use of pull bar 4 that makes band worm gear 5 safer reliable, worm gear 5 is integrated molding structures with pull bar 4, make its holding capacity strong, frangibility is not safe in utilization.
With reference to Fig. 5, Fig. 6, Fig. 7 and Fig. 8, embodiments of the invention three are a kind of window openers that the openable windows family that makes progress is opened and closed that are applicable to, its structure is as follows: described pull bar has two, be connected in the both sides of worm screw 10 respectively by worm gear 5, every pull bar is divided into two-section, wherein first of a pull bar section 4 ' and second section 4 " hinged between first section end 51 and second section front end 52; rotatable between the two; that other pull bar in like manner; first section 40 ' and second section 40 " hinged between first section end 53 and second section front end 54, rotatable between the two, article two, first of pull bar section end 51,53 upwarp, second section front end 52,54 and first sections ends 51,53 is parallel, first section 4 ', 40 ' stage casing and second section 4 "; 40 " to shrink the back at two pull bars parallel in the stage casing.
Be connected and fixed for the ease of making between pull bar and the sash, the end of described two pull bars connects by connecting rod 20, and is rotatable between connecting rod 20 and the pull bar, is useful on the mounting groove 23 and the snap close 22 of fixed sash on connecting rod.
When shaking handle 3, worm screw 10 is rotated, the worm gear 5 that drives both sides drive two pull bars do relative motion in draw close, each pull bar parts protracts, first section 4 ' of pull bar, 40 ' and second section 4 "; 40 " between become deployed condition by overlap condition, because first section end 51,53 upwarp, this moment second section front end 52,54 respectively around first section end 51,53 rotations, become deployed condition by folded state, this moment second section 4 "; 40 " the stage casing, terminal than its front end 52,54 stick up De Genggao, meet the sash that upwardly opens window and rotate and the boundary frame area of sash moves the angle of opening and bringing obliquely upward and changes around its apical axis.
