Description

Anti-rotation structure of ventilation window body fixing element

Technical Field

The utility model relates to the technical field of anti-rotation structures, in particular to an anti-rotation structure of a window fixing element of a ventilation window.

Background

The ventilation window structure is to hinge a window body on a window frame to open or close the window by pulling the window body outward or inward. The window needs to be positioned on the window frame so as not to be accidentally opened. The taiwan patent publication number is TWM403132U, the name of which is a probe connector, a spring and a movable bump are arranged in a shell, the spring normally pushes the bump outwards through the elastic thrust of the spring, and then the bump can extend out and be embedded into a positioning groove on a window frame. However, after a certain period of use, the spring may gradually lose its elasticity due to the long-term use, since the elastic fixing element can only be replaced without an adjustment mechanism.

The Chinese patent with the publication number of CN206477765U is: a window fixing element for ventilating window features that a hollow casing is provided with a screw rod, an adjusting nut, a connector and a spring, which are screwed to one end of screw rod, the connector is at another end of screw rod, and the spring is between said adjusting nut and connector for normally pushing the connector to expose part of connector to the casing for clamping it in the locating slot of window frame. Compared with the previous elastic fixing element structure, the window fixing element structure can adjust the pushing elastic force of the spring to the connector by rotating the adjusting nut, so that the service life is prolonged. However, in the process of opening and closing the window, the connector continuously abuts against the wall surface of the positioning groove under the action of the thrust of the spring, and the phenomenon of dragging occurs, so that the connector rotates, and even the adjusting nut rotates in a joint way. If the adjustment nut moves up due to rotation, the length of the spring becomes long so that the elastic force of the pushing connection head is lost, thereby weakening the fixing effect of the window.
