Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further described。

Embracing formula manual window opener in as depicted in figs. 1 and 2 a kind of, including mounting seat 1, end cap 2, drive mechanism, push-pull arm assembly and handle 5, mounting seat 1 is fixing with end cap 2 to be connected, in the accommodation space that drive mechanism is installed in mounting seat 1 and end cap 2 cooperatively forms。Drive mechanism includes the first STATEMENT OF FEDERALLY SPONSORED 31 and the second STATEMENT OF FEDERALLY SPONSORED 32, push-pull arm assembly and the second fixing connection of STATEMENT OF FEDERALLY SPONSORED 32, push-pull arm assembly includes fixing linking arm 41 and is rotationally connected arm 42, one end of fixing linking arm 41 is fixing with the second STATEMENT OF FEDERALLY SPONSORED 32 to be connected, and the other end of fixing linking arm 41 is rotatably coupled with being rotationally connected arm 42。

The end face of the contiguous end cap 2 of mounting seat 1 is extended with cylinder 11, handle 5 is provided with connecting portion 51, connecting portion 51 is through cylinder 11 and is connected with the first STATEMENT OF FEDERALLY SPONSORED 31, preferably, connecting portion 51 is connected by bolt 6 is fixing with the first STATEMENT OF FEDERALLY SPONSORED 31, and handle 5 drives the first STATEMENT OF FEDERALLY SPONSORED 31 to rotate by connecting portion 51。Second STATEMENT OF FEDERALLY SPONSORED 32 is movably set in outside cylinder 11, and the second STATEMENT OF FEDERALLY SPONSORED 32 coordinates with the first STATEMENT OF FEDERALLY SPONSORED 31 transmission, and cylinder 11 is outer to be also arranged with for limiting the torsion spring 7 that the second STATEMENT OF FEDERALLY SPONSORED 32 rotates, and the clubfoot 71 at torsion spring 7 two ends all offsets with the second STATEMENT OF FEDERALLY SPONSORED 32 and coordinates。

Specifically, the end face of contiguous second STATEMENT OF FEDERALLY SPONSORED 32 of the first STATEMENT OF FEDERALLY SPONSORED 31 is provided with the first flange 311, the end face of contiguous first STATEMENT OF FEDERALLY SPONSORED 31 of the second STATEMENT OF FEDERALLY SPONSORED 32 is respectively arranged with the second flange 321 and third lip 322, first flange 311 is inserted between the second flange 321 and third lip 322, and the first STATEMENT OF FEDERALLY SPONSORED 31 is coordinated with the second STATEMENT OF FEDERALLY SPONSORED 32 transmission by first flange the 311, second flange 321 and third lip 322；The clubfoot 71 of torsion spring 7 one end supports to be located between the first flange 311 and the second flange 321, and the clubfoot 71 of torsion spring 7 other end supports to be located between the first flange 311 and third lip 322。

Under use state, when turning handle 5 drives the first STATEMENT OF FEDERALLY SPONSORED 31 to rotate, first flange 311 of the first STATEMENT OF FEDERALLY SPONSORED 31 pushes against the corresponding clubfoot 71 of the second flange 321 (or third lip 322) and torsion spring 7, now torsion spring 7 has the trend of expansion because being subject to the active force of the first flange 311, radial clearance between torsion spring 7 and cylinder 11 is increased, so that the second STATEMENT OF FEDERALLY SPONSORED 32 and torsion spring 7 all relatively rotate with cylinder 11, second STATEMENT OF FEDERALLY SPONSORED 32 drives push-pull arm component synchronization to rotate in rotation process, it is achieved the unlatching (or closedown) to shutter；Under shutter opening, if the second STATEMENT OF FEDERALLY SPONSORED 32 is subject to the reverse masterpiece used time of push-pull arm assembly, second flange 321 (or third lip 322) of the second STATEMENT OF FEDERALLY SPONSORED 32 pushes against the corresponding clubfoot 71 of the first flange 311 and torsion spring 7, now torsion spring 7 has the trend of contraction because being subject to the active force of the second flange 321 (or third lip 322), torsion spring 7 is made to hold cylinder 11 tightly, so that the second STATEMENT OF FEDERALLY SPONSORED 32 cannot rotate relative to cylinder 11, realizing the location to shutter, now the first STATEMENT OF FEDERALLY SPONSORED 31 also cannot rotate。

This utility model is by utilizing torsion spring 7 can produce different deformation tendency when Impact direction difference, thus realizing the positioning action to the second STATEMENT OF FEDERALLY SPONSORED 32 and push-pull arm assembly, structure arranges simply, and locking positioning effect is better。Adopt and coordinated, with the second STATEMENT OF FEDERALLY SPONSORED 32, the drive mechanism constituted from the first STATEMENT OF FEDERALLY SPONSORED 31, by flange transmission between first STATEMENT OF FEDERALLY SPONSORED 31 and the second STATEMENT OF FEDERALLY SPONSORED 32, handle 5 is connected by connecting portion 51 and the first STATEMENT OF FEDERALLY SPONSORED 31, easy for installation, quick, difficulty of processing is relatively low, advantageously reduces production cost, during use, not only transmission effect is better, and advantageously reduce the stroke of handle 5 so that operating and use more convenient, service life is longer。

It is provided with the arc plate 323 matched in the outer peripheral edge with torsion spring 7 between second flange 321 and third lip 322, by arranging arc plate 323, is conducive to that torsion spring 7 is carried out radial direction spacing。First STATEMENT OF FEDERALLY SPONSORED 31 is provided with for the pressing plate 312 to torsion spring 7 axial limiting。Coordinated with arc plate 323 by pressing plate 312, be effectively increased the position degree of torsion spring 7, it is ensured that installation accuracy。

The end of connecting portion 51 is provided with the 4th flange 511, and the first STATEMENT OF FEDERALLY SPONSORED 31 is provided with the 5th flange (not shown) engaged with the 4th flange 511。By arranging the 4th flange 511 and the 5th flange, it is effectively ensured the synchronicity between handle 5 and the first STATEMENT OF FEDERALLY SPONSORED 31, it is to avoid occurring relatively rotating phenomenon between connecting portion 51 and the first STATEMENT OF FEDERALLY SPONSORED 31, result of use is better。

The above is only better embodiment of the present utility model, therefore all equivalences done according to the structure described in this utility model patent claim, feature and principle change or modify, and are all included in this utility model patent claim。
