Description

Sealing device for window gaps

technical field

The invention relates to a window gap sealing device, which belongs to the technical field of window gap sealing.

Background technique

At present, there is a lot of dust in spring in Northwest my country, and the pervasive dust has disturbed many urban residents. It seems that no matter how frequently the furniture at home is wiped, it is inevitable to touch the dust, especially for sliding windows. Given a certain window installation space, wind and sand prevention in spring has to be a difficult problem in front of everyone. Nowadays, in addition to the doors and windows for wind and sand prevention, more people choose the emerging fresh air system, which can achieve the purpose of circulating indoor air without opening the windows, but this method is expensive, and many residents are forced to accept it due to high operating costs. . Moreover, due to the poor sealing when the sliding window is closed, the outdoor noise also disturbs people's sleep. Therefore, through the study of the characteristics of wind and sand flow and the principle of mechanical sealing, the design of the plug-type sealing structure is studied for the existing windows, and a sealing with simple structure, convenient operation, and thermal insulation, heat insulation and dustproof effect is produced. The device has a broad market prospect.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a sealing device for the window gap, which can easily control the sealing of the window gap, enhance the airtightness of the window, increase its dustproof effect, and make up for the The problem of poor dust resistance of traditional sliding windows has greatly improved the development prospects.

In order to solve the above technical problems, the technical solution of the present invention is: a sealing device for a window gap, which comprises:

a fixed base, which is fixed on the sash frame and has a sliding cavity inside;

The slot card, the bottom of which coincides with the sliding track of the sash at the bottom of the outer window frame;

The rotatable card is slidably fitted in the sliding cavity of the fixed base, and can rotate circumferentially in the sliding cavity. The bottom of the rotatable card is connected with the top of the slot card; When sliding, the bottom of the connecting groove card abuts or separates from the sash sliding track of the outer window frame.

Further, in order to better ensure that the groove of the sliding track of the sash is closed during sealing and improve the airtightness of the window, the bottom of the slot card is provided with a slot sealing gasket at a position in contact with the sliding track of the sash.

Further, in order to increase the sealing performance between the adjacent sash and improve the sealing effect of the window, the sealing device for the window gap also includes an inter-frame gasket, which is arranged on the sash frame and located on the adjacent sash frame. The closure of the box.

Further, the top of the slot card is provided with a slot card hole, and the bottom of the rotatable card is installed in the slot card hole.

Further, in order to control the range of movement of the rotatable card, the fixed base has an arched fixing ring, and the rotatable card is inserted into the arched fixing ring.

Further provided is a fixing method of the fixed base, wherein the two ends of the fixed base are respectively provided with fixing parts, and the two ends of the fixed base are respectively fixed on the sash frame through the fixing parts.

Furthermore, it is not only to keep an appropriate distance between the two layers of insulating glass, and to prevent water or water vapor from entering the air cavity, so as to prevent the insulating glass from fogging and achieve sealing effect, but also to prevent heat transfer, reduce the fogging of the side glass on the indoor side, and prevent the window from being fogged. The gap sealing device also includes a spacer bar, which is arranged between two layers of hollow glass of the window sash.

After adopting the above technical solution, the rotatable card can move up and down in the sliding cavity to control the opening or closing of the slot card. The above structure can make the sealing device easier to manually operate, which makes up for the poor dustproof performance of traditional sliding windows. Insufficient, so that the prospect of development is greatly improved, the slot card and the rotatable card are connected into one through the slot card hole on the slot card, achieving the purpose of synergistic effect, and the addition of the slot gasket more effectively prevents air and Sand and dust enter the room to achieve a good thermal insulation, sound insulation and dustproof effect.

detailed description

In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, a sealing device for a window slit includes:

The fixed base 1 is fixed on the sash frame 11, and the fixed base 1 is provided with a sliding cavity; the fixed base 1 is made of a solid wear-resistant material, and its shape and size can be changed according to actual needs.

The slot card 3, its bottom coincides with the sash sliding track 4 at the bottom of the outer window frame 14; the material of the slot card 3 should ensure corrosion resistance, and its thickness can be changed according to actual needs.

The rotatable card 7 is slidably fitted in the sliding cavity of the fixed base 1, and can rotate circumferentially in the sliding cavity. The bottom of the rotatable card 7 is connected with the top of the slot card 3; when the rotatable card 7 is in the fixed When sliding in the sliding cavity of the negative film 1, the bottom of the connecting slot card abuts or separates from the sash sliding track of the outer window frame; the main body of the rotatable card 7 is composed of a cylinder, and the thickness of the main body can be adjusted according to actual needs. Change;

Wherein, the structure of the sash sliding track 4 is as follows: it is a groove, and the vertical cross-sectional shape of the groove "U" is oppositely matched, and left and right symmetrical; (i.e. the baffle plate 2), the material generally adopts a solid and foldable material, and its shape and size can be changed according to actual needs.

As shown in FIG. 2 , the bottom of the joint slot card 3 is provided with a joint slot gasket 5 at a position in contact with the sliding track 4 of the sash. The groove seal gasket 5 thickness is 2mm, and it can be separated from the bottom end of the groove card 3, and it can be assembled when the window frame is to be installed.

As shown in FIG. 2 , the window gap sealing device further includes an inter-frame gasket 8 , and the inter-frame gasket 8 is arranged on the sash frame 11 and is located at the closing position of the adjacent sash frames 11 .
