Abstract

The utility model relates to a window support. One end of the window support is connected with a fixed plate hinge in a beam groove of the window frame and the other end with a slide hinge in a lower beam groove of the window sash; a plug bolt goes through the end of the slide and holds against the inclined plane of the groove port. The utility model provides a window support which is convenient to be installed on aluminum alloy window frame. The slide block on the window sash is pulled by the support, slides along the runner of the window sash, thereby limiting the position of the window sash.

Description

Window fastener

[technical field] the utility model belongs to window fitting, more precisely window fastener.

In the time of will opeing the window in [background technology] building, need opening after sash pushed open with window fastener locking sash, building is used the aluminium alloys window frame more now, in order to strengthen tightness, increased elastic sealing strip on the flat opening window frame, close and to require the window frame weather strip that can multi-point lock be tight compact behind the window, the window frame materials adopt to have and hold the section bar that lockset transmits key way, are desirable to provide the window fastener that uses on the flat opening airproof aluminium alloys window frame that the section bar that transmits key way makes having.

[summary of the invention]

The utility model will provide a kind of being adapted to be mounted within to have the window fastener that uses on the flat opening airproof aluminium alloys window frame that the section bar that transmits key way makes.

The technical scheme that adopts is: the hinge axis hinge-coupled on strut one end and the detachable fixed head that is fixedly connected in the groove of window frame crossbeam, the other end and the interior slide block hinge-coupled of sash lower transverse beam groove of packing into, the other end of slide block has groove, and expansion bolt passes the slide block end face and withstands the notch inclined-plane.

After adopting such structure, provide a kind of being adapted to be mounted within to have the window fastener that uses on the flat opening airproof aluminium alloys window frame that the section bar that transmits key way makes.As Fig. 3, push sash open, be fixed on slide block on the sash and held along the chute slippage in the sash lower transverse beam by strut and define the sash position.When closing window, the slide block on strut and the sash is in line overlapping.Screw the bolt that withstands the notch inclined-plane on the chute, the distending slide block can compensate the long-term wearing and tearing of sliding of slide block.

[embodiment]

Embodiment 1: a kind of window fastener, as Fig. 1, Fig. 2, hinge axis (7) hinge-coupled on strut (4) one ends and the detachable fixed head (9) that is fixedly connected in the groove (14) of window frame crossbeam (12), the other end and interior slide block (1) hinge-coupled of sash lower transverse beam (11) groove (13) of packing into, the other end of slide block has groove (2), and expansion a chain for binding criminals bolt (3) passes the slide block end face and withstands groove (2) mouthful inclined-plane.

Embodiment 2: as Fig. 1, the end that strut (4) connects with window frame has cladding card (5) slidably outside strut, pan (6-2) is also arranged on the card, in the groove of the pan on the strut (6-1) back spring is arranged, one end of spring is pressed against on the strut, and the other end of spring presses card (5) and enters in the anticreep groove (8) on the fixed block hinge axis (7).Other are with embodiment 1.

The card compression spring that promotes on the strut makes the card pan align with the bar pan, is enclosed within on the hinge axis on the fixed head.The actuating card of card compression spring resets, and embeds in the anticreep groove on the fixed block hinge axis.Avoid strut and rotating shaft slippage.

Embodiment 3: as Fig. 3, in the detachable slide block (1) and the groove (13) between the sash rotating shaft (15) that is fixedly connected in the groove (13) of sash lower transverse beam (11) of locating piece (10).Other are with embodiment 2.

When windowing, running fix piece position can change the maximum opening angle that sash is opened.When slide block is run into locating piece, just define the maximum opening angle that sash is opened.
