CN209838219U - Lower frame and drain hole of casement window - Google Patents

Abstract

The utility model provides a flat-open window lower frame and wash port, the problem that solve is: how to prevent the drain hole from being blocked. The utility model has the following main points: the main section bar is a section bar with a cross section in a Chinese character 'xi' shape, wherein the opening part is arranged on the upper part and faces outwards, and a drainage hole is arranged on the upper side plate of the drainage groove. Thus, the window sash limiting edge of the utility model is not provided with a drain hole. The drainage path is as follows: the accumulated water on the surface of the side plate on the lower frame of the window frame, namely the drainage groove, sequentially passes through the drainage hole on the side plate on the drainage groove, the drainage groove and the notch of the drainage groove to drain water outwards. The utility model has the advantages that: the invisible drain hole is formed, so that the phenomenon that outdoor impurities and dust easily enter the drain hole directly is avoided; secondly, ponding at the window frame lower frame flows into the water drainage tank through the wash port downwards, has improved drainage efficiency.

Description

Lower frame and drain hole of casement window

Technical Field

The utility model relates to a flat-open window, the lower frame of flat-open window frame and wash port specifically says so.

Background

Referring to fig. 1, a lower frame 1 of a conventional casement window frame includes a main sectional material 13 and a sash limiting edge 11 (also called a sash baffle), the main sectional material is a horizontal square tube for supporting, the cross section of the main sectional material is square, the sash limiting edge is located at the upper part of the main sectional material, and the outdoor side of the sash abuts against the limiting edge when the window is closed. And a drainage hole 12 is formed on the limiting edge, and accumulated water on the lower frame of the window frame is drained outwards horizontally through the drainage hole. Because the drainage hole is arranged on the limiting edge and faces outdoors, outdoor impurities and dust can easily enter the drainage hole directly to cause the blockage of the drainage hole and influence the drainage effect; secondly, ponding at the window frame lower frame outwards drains water in the horizontal mode, influences drainage efficiency.

Disclosure of Invention

In order to solve the technical problem, the utility model aims at providing a lower frame of casement window and wash port.

The purpose of the utility model is realized like this: the shape of the lower frame main body section is improved, specifically, a square tube with a square section is changed into a section with an inverted cross-section, a groove on the upper half part of the main body section is called a drainage groove, the notch of the drainage groove faces the outside, and a drainage hole is arranged on the upper side plate of the drainage groove. Thus, the window sash limiting edge of the utility model is not provided with a drain hole. Use the utility model discloses replace current main part section bar, main part section bar sectional geometry and the spacing limit of casement do not change promptly. The drainage path is as follows: ponding on the side plate surface on the side plate on the frame lower frame is the drain tank, flows into the drain tank downwards through the wash port on the side plate on the drain tank, outwards drains water from the notch of drain tank again.

Compared with the prior art, the utility model has the positive effects that: because the drain hole is arranged on the upper side plate of the drain tank, the drain hole is not opposite to the outdoor, and a hidden drain hole is formed, thereby avoiding the phenomenon that outdoor impurities and dust easily enter the drain hole directly; secondly, the drainage path is through the drain hole on the drain tank upper side board downward inflow drain tank, has improved drainage efficiency.

Drawings

The present invention will be further described with reference to the accompanying drawings.

Fig. 2 is the section schematic view of the lower frame section of the aluminum-plastic aluminum casement window frame of the utility model.

Detailed Description

Referring to fig. 2, the shape of the lower frame main body section bar 1 is improved, specifically, a square tube with a square section is changed into a section bar with an inverted cross-section, a groove in the upper half of the main body section bar is called a drainage groove 13, a notch of the drainage groove faces the outside, and a drainage hole 12 is arranged on an upper side plate of the drainage groove. Thus, the window sash limiting edge 2 of the utility model is not provided with a drain hole any more. Use the utility model discloses replace current main part section bar, main part section bar sectional geometry and the spacing limit of casement do not change promptly. The drainage path is as follows: ponding on the side plate surface on the side plate on the frame lower frame is the drain tank, flows into the drain tank downwards through the wash port on the side plate on the drain tank, outwards drains water from the notch of drain tank again.
