Description

Technical Field

[0001] The utility model relates to the technical field of plastic-steel window sealing, in particular to an easy-to-slide plastic-steel window with good sealing effect. Background Art

[0002] When the current plastic-steel windows are in use, since the bottom of the plastic-steel windows needs to be constantly pushed and pulled left and right, air leakage is easy to occur between the bottom of the plastic-steel windows and the plastic-steel window tracks. Especially in the north, when the range hood is turned on, a low-pressure environment is formed indoors and the outdoor wind pressure increases. The plastic-steel windows often have poor sealing effects at the bottom, causing wind to invade the room through the gaps, which not only affects the indoor comfort, but may also cause noise, dust and other problems, and even affect the exhaust effect of the range hood, aggravating kitchen fume pollution. Therefore, we have improved some structures of the plastic-steel windows and plastic-steel window tracks to enhance the sealing effect of their sealing points. Utility Model Content

[0003] The technical problem to be solved by the utility model is to address the deficiencies of the existing technology and provide an easy-to-slide plastic-steel window with a handle that can be quickly opened and closed and has a good sealing effect while providing certain anti-theft safety performance.

[0004] The technical problem to be solved by the utility model is achieved through the following technical solutions: a sliding plastic-steel window with good sealing effect, comprising a plastic-steel window embedded in a window track, a sliding sealing mechanism provided between the bottom of the plastic-steel window and the window track, the sliding sealing mechanism comprising:

[0005] The sealing strip partition is fixed vertically on the bottom surface of the window track, thereby dividing the window track into two sealing grooves, one inner and one outer. A guide groove for inserting the sealing strip partition is opened on the bottom wall of the plastic-steel window;

[0006] Two U-shaped sealing strips, both of which are transversely arranged in the window track and with their outer circumferences in contact with the bottom surface of the window track, the U-shaped sealing strip having one end with a groove as an open end and the other end as a raised end, the raised ends of the two sealing strips both abutting against a side wall of the sealing strip partition;

[0007] There are two sets of roller mechanisms, each sealing groove has a set of said roller mechanisms, the upper end of the roller mechanism is set as the installation end fixed on the bottom surface of the plastic steel window, and the lower end is the sliding end that slides in contact with the top surface of the U-shaped sealing strip.

[0008] The technical problem to be solved by the present invention can also be achieved through the following technical solutions. The above-mentioned easy-to-slide plastic-steel window with good sealing effect, the roller mechanism includes a column, a channel steel and a roller, the top of the column is vertically fixed on the bottom surface of the plastic-steel window, the channel steel is fixedly installed on the bottom surface of the column, and the roller is hinged on the inner wall of the channel steel.

[0009] The technical problem to be solved by the present invention can also be achieved through the following technical solutions: in the above-mentioned easy-to-slide plastic-steel window with good sealing effect, the bottom surface of the column is formed into an inclined plane with an angle of 15° to the horizontal plane.

[0010] The technical problem to be solved by the present invention can also be achieved through the following technical solutions. In the above-mentioned easy-to-slide plastic-steel window with good sealing effect, a felt is fixed on one end surface of the guide groove parallel to the top surface of the sealing strip partition.

[0011] Compared with the prior art, the beneficial technical effects of the present invention are:

[0012] (1) The window track is divided into two inner and outer sealing grooves by the sealing strip partition. With the use of two U-shaped sealing strips, a multiple sealing structure is formed. Under the action of the gravity of the plastic steel window, the U-shaped sealing strip is squeezed, so that the U-shaped sealing strip fits tightly with the bottom surface of the window track, and the two ends of the U-shaped sealing strip are respectively abutted against the inner wall of the sealing groove, which greatly reduces the gap and effectively prevents air leakage.

[0013] (2) The design of the roller mechanism enables the plastic-steel window to easily overcome friction during the sliding process and achieve smooth movement. The bottom surface of the column is tilted, which allows the outer surface of the roller to better contact the arc-shaped outer surface of the U-shaped sealing strip, ensuring the sealing effect between the two and extending the service life.

[0014] (3) The setting of the felt in the guide groove further enhances the sealing effect, while also reducing the noise and vibration during pushing and pulling, improving the user experience and being highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1, with reference to Figure 1-3 A sliding plastic-steel window with good sealing effect comprises a plastic-steel window 2 embedded in a window track 1, the plastic-steel window 2 is formed into a substantially square frame-shaped window structure, a sliding sealing mechanism is provided between the bottom of the plastic-steel window 2 and the window track 1, the sliding sealing mechanism comprising;

[0022] The sealing strip partition 3 is formed into a roughly square plate-shaped structure, which is vertically fixed to the bottom surface of the window track 1, thereby dividing the window track 1 into two sealing grooves, one inner and one outer. The sealing groove is formed into a square groove structure. A guide groove 4 for inserting the sealing strip partition 3 is opened on the bottom wall of the plastic-steel window 2. The guide groove 4 is formed into a square groove structure. A felt is fixed on one end surface of the guide groove 4 parallel to the top surface of the sealing strip partition 3.
