Description

Novel lower window frame structure

Technical Field

The utility model relates to a door and window section bar technical field especially involves a novel lower window frame structure.

Background

The lower window frame of existing window frames is usually provided with a screen track, so that the lower window frame profile presents two structures: (1) the screen window track is directly arranged on the outer side of the lower window frame section, and the screen window has the defects that the screen window can derail and fall off when being installed and used, so that potential safety hazards are caused, mosquitoes and insects easily enter a room from the lower edge of the screen window track, and the actual effect of the screen window is influenced; (2) the screen window rail is externally provided with a baffle or a flange, and the defects that the baffle and the flange are usually integrated with the main body of the lower window frame section bar, so that the material consumption of the lower window frame section bar is increased, the weight of the lower window frame section bar is increased, the volume of the lower window frame section bar is also increased, and the transportation and the cost control are not facilitated.

Disclosure of Invention

In view of this, the utility model aims at providing a simple structure, can improve the novel lower window frame structure of security.

In order to solve the technical problem, the technical scheme of the utility model is that:

the utility model provides a novel lower window frame structure, includes window frame section bar down and by interior casement track, outer casement track and the screen window track of inside-out shaping on window frame section bar down the outside shaping of window frame section bar has L type flange down, L type flange is in with the form shaping of cantilever the outside of window frame section bar is surperficial down.

Preferably, the L-shaped rib is formed at an upper portion of an outer side surface of the lower window frame profile.

Preferably, the top of the vertical edge of the L-shaped rib is higher than the horizontal plane of the outer sash rail and the screen rail.

Preferably, the outer sash track and the screen window track are located on the same horizontal plane, and the horizontal plane of the inner sash track is higher than the horizontal planes of the outer sash track and the screen window track, so that the horizontal planes of the inner sash track, the outer sash track and the screen window track form a ladder shape.

Furthermore, an inverted T-shaped slot is formed in a stepped vertical surface formed by the inner sash track, the outer sash track and the screen window track, and an inserting strip is installed in the inverted T-shaped slot.

Furthermore, the cutting is provided with a plush outer surface for reducing the collision friction between the lower side of the outer sash and the lower frame profile.

Furthermore, the outer surface of the inserting strip is molded into a silica gel material and used for buffering the collision between the side surface of the lower part of the outer window sash and the lower window frame section.

The utility model discloses technical effect mainly embodies in following aspect: the L-shaped flanges are formed outwards on the outer sides of the lower window frame sectional materials and are arranged on the upper portions of the outer side surfaces of the lower window frame sectional materials in a cantilever mode, so that the L-shaped flanges have the functions of preventing the screen window from derailing and falling and shielding the gap of the lower edge of the screen window under the condition that materials are reduced as far as possible, the production cost and the transportation cost are reduced, and the safety can be improved.

Drawings

Fig. 1 is a schematic view of the structure of the lower window frame section of the present invention.

Detailed Description

The following detailed description will be made with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master, and for convenience of understanding, the left side of the attached drawings of the present invention is defined as the outside, and the right side is defined as the inside.

As shown in fig. 1, a novel lower window frame structure includes a lower window frame section bar 1, and an inner sash rail 11, an outer sash rail 12, and a screen window rail 13 formed on the lower window frame section bar 1 from inside to outside, wherein an L-shaped rib 14 is formed outside the lower window frame section bar 1, the L-shaped rib 14 is formed on an outer side surface 1a of the lower window frame section bar 1 in a cantilever manner, the position where the L-shaped rib 14 is formed is specifically on an upper portion of the outer side surface 1a of the lower window frame section bar 1, and may be specifically one fifth of the outer side surface 1a of the lower window frame section bar 1, and a vertical edge top of the L-shaped rib 14 is higher than horizontal planes of the outer sash rail 12 and the screen window rail 13, so as to ensure that the L-shaped rib 14 can play a role in preventing screen window derailing and dropping.

The outer sash rail 12 and the screen window rail 13 are positioned on the same horizontal plane, and the horizontal plane of the inner sash rail 11 is higher than the horizontal planes of the outer sash rail 12 and the screen window rail 13, so that the horizontal planes of the inner sash rail 11, the outer sash rail 12 and the screen window rail 13 form a ladder shape, the screen window and the outer sash are conveniently installed firstly, and then the inner sash is installed.

An inverted T-shaped slot 15 is formed in a stepped vertical surface formed by the inner sash rail 11, the outer sash rail 12 and the screen window rail 13, an inserting strip is installed in the inverted T-shaped slot 15, and the inserting strip is provided with a plush-shaped outer surface and used for reducing collision friction between the lower side surface of the outer sash and a lower window frame section; or the outer surface of the inserting strip is molded into a silica gel material and used for buffering the collision between the side surface of the lower part of the outer window sash and the lower window frame section.
