Description

A kind of plastic window frame section bar

The utility model relates to a kind of plastic window frame section bar, particularly relates to the middle frame section in the window frame profile.

The modified section bar of the split-type structural window that to be transom and sash be combined as a whole by the splicing frame of the center in the plastic window frame section bar, its effect is a cancellation splicing frame, simplified structure, the base of transom and the top margin of sash are integrated, form a kind of specific structure, following dress sliding window sash, top dress transom.Frame section in of the prior art has forms such as two rail formulas and three rail formulas.Its cross sectional shape of frame section is " H " shape greatly in the two rail formulas, and as shown in Figure 1, getting on the right track of center can only be adorned fixed sash, i.e. two glazing beads of transom, and needs fix glass; Its cross sectional shape of frame section is " H " shape of two amalgamations in the three rail formulas, as shown in Figure 2, getting on the right track of center also can only be adorned transom, and needs two glazing beads to fix glass, needs a cover plate that the illusory screen door track in center top is covered in addition.Its weak point is: (1) these two kinds of forms all need two glazing beads to fix glass, are positioned at outdoor glazing bead and are very easily pried open, and make the robber that the chance of burglary be arranged, and lack theftproof; (2) getting on the right track of these two kinds of forms can only be adorned transom, can't adopt the form of casement window; (3) adopt this two kinds of structures, particularly three rail formula centers owing to illusory structure is arranged and need more press strip, expend more material.

The purpose of this utility model provides a kind of middle frame section with higher theftproof.

The utility model is achieved in that a kind of plastic window frame section bar, comprise a strip center main body, it is characterized in that: described center lower body part has two tracks, top has a frame, and the section of center main body is " h " shape, and the lower railway of center main body can be adorned sliding sash, get on the right track and be " L " shape, both transom can be installed, promptly fixed casement window can be installed casement window again.

Be that the section of frame section is in the bottom of center main body increases a screen door track, be whole as another kind of form of the present utility model

Shape.

The utlity model has many advantages: (1) center main body section adopts above-mentioned " h " shape structure, when making window frame top make transom installation glass, the glass one side is near the frame on center top, another side gets final product by glazing bead is fixing indoor, this makes transom be pried open in outdoor being difficult to, and has therefore improved the theftproof of window widely; (2) because center top is L-shaped, makes window frame top not only can make transom, and can also adopt the form of casement window; Reduced the glazing bead of half when (3) transom being installed, and cancelled the screen door track on center top, need not use cover plate, therefore saved material greatly, thereby improved the exit window rate of plastic raw materials owing to window frame top; (4) adopt plastic window frame of the present utility model, outward appearance is lightly attractive in appearance, and because the height of glazing bead is reduced, thereby can increase the transom daylighting area.

Below in conjunction with drawings and Examples the utility model is further described.
