Abstract

The utility model relates to a sliding window, which mainly comprises a window sash, a window frame, a wind-shielding block, a water drainage pipe and a non-return valve, wherein, the middle part of the wind-shielding block is provided with a groove; the side wall of a guide track at a relevant position is provided with a water drainage hole; the water inlet end of the water drainage pipe is connected with a water drainage hole on the side wall of the window frame, and the water outlet end of the water drainage pipe is connected with the non-return valve. The utility model has the advantages that the utility model can effectively drain and choke, enhance the water-tightness and air-tightness of the sliding window, and enlarge the application field of the sliding window.

Description

Sliding window high sealing performance

The utility model relates to general window, specifically is a kind of sliding sash of high leakproofness.

The sliding sash sealing performance of using is relatively poor at present.This window to enter the rainwater between the guide rail and is provided with drain hole in order to discharge, therefore not only make atmosphere in the drain hole inlet chamber, reduced tightness, and when outside wind pressure is big, rainwater can flow backwards into indoor from drain hole, therefore also greatly reduces watertightness performance.

Main purpose of the present utility model provides a kind of improved sliding sash, makes the sliding sash after the improvement, has higher tightness, watertightness.

Realize above-mentioned purpose the utility model, include the piece that keeps out the wind, gutter, flap valve.The water inlet end of gutter connects the drain hole of window frame, and the water side of gutter connects flap valve.The water side of gutter is lower than the water inlet end of gutter.The piece that keeps out the wind is middle to be a groove, at the sash guide sidewall corresponding with groove, is provided with a drain hole to the outdoor direction perforation.The guiding cheekn bottom of the outdoor side of the piece that keeps out the wind is provided with a drain hole to the outdoor direction perforation.The drain hole lower edge is the reinforcing rib that has a down dip in guide rail bottom.The sliding sash of structure like this, closure of check ring when outside wind pressure increases stops in the air-flow inlet chamber, when rainwater gathers, the flap valve opening water discharge.

Therefore the utility model is a kind of draining by all kinds of means, utilizes the flap valve single slope drainage, stops the sliding sash in the air-flow inlet chamber.See that thus major advantage of the present utility model is, compared with prior art, under condition of similarity, can improve the tightness and the watertightness of sliding sash, obviously improved the applicability of sliding sash and the economy of building.

Description of drawings:

Fig. 1 is a cross-sectional schematic of the present utility model.

Fig. 2 is an outdoor facade perspective diagram of the present utility model.

A preferred embodiment of the present utility model as shown in drawings.Below in conjunction with accompanying drawing and example the utility model is specified.

See that by Fig. 1 the utility model sliding sash mainly is made of keep out the wind piece 10 of two sash, 1,15, one window frames, 5, one gutters, 7, one flap valve 8.In the present embodiment two

sash

1,15 be located in respectively with

On two

guide rails

2,16 of window frame 5 one.One piece 10 that keeps out the wind is installed, draining between two

guide rails

2,16

The water inlet end of pipe 7 connects the drain hole 6 of window frame 5 sidewalls bottom, and its water side connects flap valve 8.One check valve 9 is installed on the flap valve 8.Be to cooperate draining, the sidewall bottom of the guide rail 2 of the both sides that (see also accompanying drawing 2) about the groove of piece 10 that keeps out the wind is through with

drain hole

3,4 and 13,14 respectively from inside to outside.

Unimpeded for ease of

drain hole

3,4,13,14 (see figure 2) drainings as Fig. 1 finding the utility model, between the

drain hole

3 and 4, the lower edge between the drain hole 13 and 14 is a downward-sloping reinforcing rib 12.

Working method of the present utility model as shown in Figure 2.See that by figure when rainwater entered between sash 15 and the guide rail 2, rainwater was discharged from drain hole 13,14.When rainwater entered in the groove of the piece 10 that keeps out the wind, rainwater was discharged from drain hole 3,4.When rainwater enters between sash 1 and the guide rail 16, rainwater from bottom discharge hole 11 via drain hole 6, gutter 7, flap valve 8, back down check valve 9 and discharge.When outside wind pressure strengthens, or the rainfall blast is when increasing simultaneously, and valve 9 is closed, and stops in air-flow and the rainwater inlet chamber.
