Description

A utility window that is convenient to clean and can be fully opened

technical field

The utility model relates to the field of building doors and windows, in particular to a practical window that can be fully opened for convenience and cleaning.

Background technique

The windows used in the prior art are generally of the structure of a sliding window or a casement window. For a movable window sliding on a flat rail, it slides on a flat rail, and rollers are required below. Since the service life of the rollers is not long for such a movable window, once it is necrotic , it will be very difficult to open the movable window, and it is very troublesome to replace the rollers, which will reduce the service life of the overall movable window, and the degree of firmness is low, the air tightness is poor when closed, and the anti-shock safety is poor;

The sash of the casement window is combined with the window frame through the hinge. The sash can be rotated and opened. The structure is simple. The whole window can be opened on both sides at the same time. At the same time, it is inconvenient to clean the outside of both when cleaning.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a practical window that is simple in structure, easy to use, good in sealing, high in flexibility, and easy to clean.

The purpose of this utility model is achieved through the following technical solutions:

A practical window that is convenient to clean and can be fully opened. Window frame connection.

In the utility model, a rectangular frame is arranged inside the middle fan, and the rotating shaft is divided into upper and lower two short shafts and fixed on the rectangular frame. The joint surface of the side fan and the middle fan is a convex groove. A notch is provided at the joint between the edge of the window frame and the side sash.

Due to the adoption of the above technical scheme, the utility model solves the problem that the casement window takes up a large space when opening the sash and the problem that the sliding window cannot be opened 100%. Since the middle sash is connected with the window frame through the rotating shaft, the middle sash can be placed in the window frame at 360 degrees. Rotate at a high degree, if you need greater ventilation, you can rotate the two side fans to the sides of the middle fan, and then rotate the middle fan around the vertical axis to the required angle to meet the ventilation requirements; when cleaning, because the middle fan can rotate 360 degrees around the axis Rotate, so you can easily clean both sides of the three sashes only indoors, which is convenient and safe.

In summary, the utility model, a practical window that can be fully opened with convenience and cleaning, has the advantages of simple structure, convenient use, good sealing performance, high flexibility, and convenient cleaning, and is suitable for industrial production.

Detailed ways

Below in conjunction with the accompanying drawings, the specific implementation of the practical window that is convenient for cleaning and can be fully opened will be described in detail.

As shown in Figures 1 and 2, a utility window that is convenient to clean and can be fully opened includes a window frame 1 and a window sash 2. The window sash 2 includes a middle sash 3 and two side sash 4. The two sides of the sash 3, the middle sash 3 is connected with the window frame 1 through a rotating shaft.

In the present utility model, as shown in FIG. 7 , a rectangular frame 7 is arranged inside the middle fan 3 , and the rotating shaft 8 is divided into upper and lower two short shafts and fixed on the rectangular frame 7 . The joint surface of the side fan 4 and the middle fan 3 is a convex groove. A notch 5 is provided at the joint between the edge of the window frame 1 and the side leaf 4 .

As shown in Fig. 3, 4, 5, 6, in the utility model, the window sash 2 is divided into three leaves with the same size, the middle leaf 3 can rotate around the rotating shaft 8 connected to the window frame 1, and the two side leaves 4 are connected with the middle leaf by a hinge (hinge). The fan 3 is connected and can turn to the front and back sides of the middle fan 3 around the edge axis of the middle fan 3 .

In order to improve the airtightness of the utility model, the contact surface between the side fan 4 and the middle fan 3 is in the form of concave-convex grooves. At the same time, a notch 5 is provided at the joint between the edge of the window frame 1 and the side leaf 4 . Middle fan 3 can not be the form of notch 5 because will rotate, can add sealing strip up and down in middle fan 3 to improve airtightness.

Since the middle fan 3 is rotated by the rotating shaft 8, and the rotating shaft 8 does not pass through the middle fan 3, the rotation of the middle fan 3 by the two short shafts at the upper and lower ends has relatively high requirements on components and processes. The following methods can be used to solve the problem: in the middle fan 3 Make a rectangular frame 7 inside, fix the two minor axes on the rectangular frame 7 to form an integral frame, and then assemble the external profiles.

Some positions of the window sash 2 in the window frame 1 need to be fixed, which can be realized by structural members such as bolts and slide grooves, or by the frictional damping of the rotation of the window sash 2. The window frame 1 can be of ordinary linear shape or corresponding It is based on the three-segment broken-line shape of the three sashes to increase its artistic beauty and rotational orientation.

When opening the window at ordinary times, only the two side fans 4 can be rotated to the two sides of the middle fan 3 to meet the ventilation requirements without taking up space.

If greater ventilation is required, after the two side fans 4 are rotated to both sides of the middle fan 3, the middle fan 3 is rotated around the rotating shaft 8 to a required angle to realize the ventilation requirement.

When cleaning, since the middle fan 3 can rotate freely around the rotating shaft 8, it is convenient and safe to clean both sides of the three sashes only indoors.
