Description

Special-purpose Switch for door and window driver and snap close

Technical field

The utility model belongs to the Switch for door and window driver installed on the door and window that the steel-plastic coextrusion section bar constitutes and the improvement of snap close, particularly special-purpose Switch for door and window driver and snap close.

Background technology

The steel-plastic coextrusion section bar is a kind of special-purpose section of novel making door and window, and this novel section bar is compared with the common PVC plastic material, is all to be better than the common PVC plastic material on quality, intensity and practicality.In production and use, common door and window switch driver and snap close are installed on the door and window of steel-plastic coextrusion section bar making.The sector gear of common door and window switch driver has the rotating shaft of square hole and driver rack shaft hole movingly, and two fixed supporting leg riveted and fixed are just passed through on the pedestal of driver in the bottom of driver support, the riveted joint contact surface is little, intensity is low, application life is short, and after using a period of time, the riveting point is loosening, the driver support is come off, and switch driver is damaged.Snap close is the rib that the both sides in central screw hole on the holder are being provided with symmetry.Its holder is narrow, only passes through a screw on doorframe and window frame, and fixedly contact area is little, and intensity is low, is easy to damage.

Summary of the invention

The purpose of this utility model is to provide a kind of special-purpose Switch for door and window driver and snap close, the special-purpose Switch for door and window driver of installing on the door and window that the plastic-steel co-extrusion section bar is constituted uses flexibly, switch is convenient, and the syndeton contact area of switch driver and pedestal is big, the fastness that connects is reliable, snap close and doorframe and window frame contact area are big, and the intensity height strengthens its application life.

The purpose of this utility model is achieved in that a kind of special-purpose Switch for door and window driver and snap close, comprise that supporting the driver support that sector gear is installed is fixed on the pedestal, the centre is evenly equipped with perforation, two ends are connected with the drive link of pin respectively, its uniform perforation matches with sector gear, pin matches with the gathering sill at pedestal two ends respectively, on the dual-side at flat-shaped pedestal middle part, offer the groove of symmetry respectively, on the dual-side at flat-shaped drive link middle part, offer the groove of symmetry respectively, wherein the groove of drive link is longer than the groove of pedestal, the Connection Block of driver support bottom matches with the groove of pedestal both sides, and snap together with pedestal, the guide groove of driver support is slidingly matched with the drive link of offering the groove section.The snap close that cooperates with pin is being for being provided with the symmetrical rib that has the central screw hole in a fixing side of seat surface, at the fixing opposite side of seat surface two screw holes with central screw hole symmetry is being set.

Because the Connection Block of the utility model driver support bottom matches with the groove of pedestal both sides, and snaps together with pedestal.The Connection Block of driver support is wrapped on the pedestal, and the groove by the pedestal both sides fixes, be installed on the pedestal with making driver support fastness, contact area is big, the working strength height, the phenomenon of having avoided driver support and pedestal riveting point to become flexible, come off has strengthened application life of the present utility model effectively.Owing on the fixedly seat surface of snap close, increased by 2 screw holes, seat surface is widened.Snap close be by three screw on doorframe and window frame.Increased and installed and fixed area and bonding strength, made door-window section bar not easy-to-draw bad, improved the application life of door and window greatly, and made the locking of door and window more reliable.
