Description

Technical Field

[0001] This utility model relates to the field of door and window technology, and in particular to a window frame profile and a sliding door and window. Background Technology

[0002] With technological advancements, automatically moving sliding doors and windows have emerged on the market. These types of sliding doors and windows typically have an actuator installed on the top side of the window frame. The actuator is connected to at least one movable door leaf via a connector, causing the movable door leaf to move back and forth within the window frame. Because space needs to be reserved on the top side of the window frame for the actuator installation, air convection occurs between the indoor and outdoor air during use. This can generate significant wind noise, especially when outdoor wind pressure is high, at the top of the window frame. Therefore, there is an urgent need for a window frame material with better sealing performance. Utility Model Content

[0003] The purpose of this utility model is to provide a window frame profile and a sliding door / window to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A window frame profile includes: an upper frame with a front guide rail and a rear guide rail arranged on the bottom side along the front-rear direction, wherein an installation area is formed between the front guide rail and the rear guide rail; and a retaining frame connected to the front guide rail and partially obscuring the installation area, wherein an avoidance gap is formed between the retaining frame and the rear guide rail.

[0006] This technical solution has at least the following beneficial effects: During installation, the upper frame is located above the external movable sash. The front and rear guide rails limit the top positions of the two movable sashes, allowing them to move left and right relative to the upper frame. Electrical components that drive the movable sashes are installed between the front and rear guide rails. At this time, the baffle can partially cover the installation area, leaving only a clearance between the baffle and the rear guide rail for the electrical components to drive the movable sash located at the rear. This effectively reduces the convection of indoor and outdoor air through the installation area, thereby improving the airtightness of the window frame profile. By partially covering the area where the electrical components are installed on the upper frame with the baffle, the overall insulation and airtightness of the window are improved, and noise problems under high wind pressure are effectively reduced, thus improving user comfort.

[0007] As a further improvement to the above technical solution, the baffle frame includes a baffle and a connecting plate. The connecting plate is connected to the front guide rail, the baffle is connected to the top of the connecting plate and extends rearward, and the clearance gap is formed between the baffle and the rear guide rail.

[0008] As a further improvement to the above technical solution, an upper hook is formed on the top side of the connecting plate, and a lower hook is formed on the bottom side of the connecting plate. The upper hook and the lower hook are respectively engaged with the front guide rail.

[0009] As a further improvement to the above technical solution, an upwardly bent connecting hook is formed on the rear side of the front guide rail, a pressure rib is provided on the bottom side of the front guide rail, the lower hook forms an upwardly facing slot, an elastic body is placed in the slot, the pressure rib presses down against the elastic body and enters the slot, and the upper hook engages with the connecting hook.

[0010] As a further improvement to the above technical solution, a downwardly extending partition is connected to the bottom side of the baffle, and the partition is spaced apart from the connecting plate.

[0011] As a further improvement to the above technical solution, the front and rear sides of the partition are respectively provided with first brush grooves.

[0012] As a further improvement to the above technical solution, a second sliver groove is provided on the front side of the rear guide rail.

[0013] A sliding door and window includes a front movable sash, a rear movable sash, and the aforementioned window frame profile. The front guide rail extends into the top of the front movable sash, and the rear guide rail extends into the top of the rear movable sash. A driver is provided on the bottom side of the upper frame at the installation area. The driver is driven by a transmission plate, and the driver can drive the transmission plate to move left and right. The transmission plate passes through the clearance gap and is connected to the rear movable sash.

[0014] This technical solution has at least the following beneficial effects: During installation, the upper frame is located above the external movable sash. The front and rear guide rails limit the top positions of the front and rear movable sashes respectively, improving the stability of their left and right movements. The drive unit is installed in the installation area formed between the front and rear guide rails. At this time, the baffle can cover part of the installation area, leaving only the clearance between the baffle and the rear guide rail for the transmission plate to connect with the rear movable sash. This effectively reduces the convection of indoor and outdoor air through the installation area, thereby improving the airtightness of the window frame profile. In this way, the baffle partially covers the area where electrical components are installed on the upper frame, improving the thermal insulation and airtightness of the sliding doors and windows, effectively reducing noise problems when the wind pressure is high, and improving user comfort.

[0015] As a further improvement to the above technical solution, a first adhesive strip groove is provided on the rear side of the top of the front movable fan, corresponding to the position of the baffle frame.

[0016] As a further improvement to the above technical solution, a second rubber strip groove is provided on the top of the rear movable fan corresponding to the position of the transmission plate.

[0027] Reference Figure 1 A window frame profile includes an upper frame 100 and a backrest. The lower side of the upper frame 100 is provided with a front guide rail 110 and a rear guide rail 120 along the front-to-back direction. An installation area 130 is formed between the front guide rail 110 and the rear guide rail 120. The backrest is connected to the front guide rail 110 and partially covers the installation area 130. An clearance gap 140 is formed between the backrest and the rear guide rail 120. In practical applications, the front guide rail 110 may be located on the outdoor side and the corresponding rear guide rail 120 may be located on the indoor side, or the front guide rail 110 may be located on the indoor side and the corresponding rear guide rail 120 may be located on the outdoor side.

[0028] As described above, during installation, the upper frame 100 is located above the external movable sash. The front guide rail 110 and the rear guide rail 120 respectively limit the top position of the two movable sashes, allowing the two movable sashes to move left and right relative to the upper frame 100. Electrical components that drive the movable sashes are installed between the front guide rail 110 and the rear guide rail 120. At this time, the baffle can cover part of the installation area 130, leaving only the clearance 140 between the baffle and the rear guide rail 120 for the electrical components to be connected to the movable sash located at the rear. This can effectively reduce the convection of indoor and outdoor air through the installation area 130, thereby improving the airtightness of the window frame profile. In this way, by partially covering the area of ​​the upper frame 100 where the electrical components are installed by the baffle, the overall heat insulation and airtightness of the window are improved, and the noise problem when the wind pressure is high is effectively reduced, thus improving the comfort of use.

[0029] The baffle is mainly used to partially cover the mounting area 130 at the bottom of the front guide rail 110 and the rear guide rail 120, thereby reducing the exposure of the mounting area 130. It has various structural forms. In this embodiment, the baffle includes a baffle 210 and a connecting plate 220. The connecting plate 220 is connected to the front guide rail 110, and the baffle 210 is connected to the top of the connecting plate 220 and extends rearward. The clearance gap 140 is formed between the baffle 210 and the rear guide rail 120. The connecting plate 220 is mainly used to connect with the front guide rail 110, so that the entire baffle is relatively fixed at the installation area 130. The baffle 210 extends horizontally and mainly serves to shield the installation area 130. It also avoids the two movable fans by cooperating with the front guide rail 110 and the rear guide rail 120 respectively. In use, the front guide rail 110 and the connecting plate 220 can be inserted into the interior of one movable fan, while the baffle 210 extends above the other movable fan, forming a clearance gap 140 with the rear guide rail 120 for the transmission connection of the power supply components located at the rear movable fan.

[0030] There are several ways to connect the connecting plate 220 to the front guide rail 110. For example, the connecting plate 220 and the front guide rail 110 can be fixed by screws. In this embodiment, the top side of the connecting plate 220 has an upper hook 221, and the bottom side of the connecting plate 220 has a lower hook 222. The upper hook 221 and the lower hook 222 are respectively engaged with the front guide rail 110. During installation, the connecting plate 220 can be detached from the front guide rail 110 first. After the electrical components are installed in the installation area 130, the connecting plate 220 is then connected to the guide rail. At this time, the upper hook 221 on the top side and the lower hook 222 on the bottom side of the connecting plate 220 are respectively engaged with the front guide rail 110, which can realize the quick installation of the connecting plate 220. When maintenance of the electrical components is required, the upper hook 221 and the lower hook 222 can be removed from the front guide rail 110, improving the convenience of maintenance.

[0031] To improve the tightness of the connection between the connecting plate 220 and the front guide rail 110, in this embodiment, an upwardly bent connecting hook 111 is formed on the rear side of the front guide rail 110, a pressure rib is provided on the bottom side of the front guide rail 110, and the lower hook 222 forms an upwardly facing slot. An elastic body 223 is placed in the slot. The pressure rib presses down against the elastic body 223 and enters the slot. The upper hook 221 engages with the connecting hook 111. Naturally, the upper hook 221 is a downwardly bent hook-shaped structure, so as to engage with the connecting hook 111. In practical applications, the elastic body 223 can be made of materials such as rubber, and the elastic body 223 extends along the length direction of the slot. When connecting the connecting plate 220 to the front guide rail 110, align the pressure rib on the bottom side of the front guide rail 110 with the slot of the lower hook 222, and then move the connecting plate 220 upward. At this time, the pressure rib presses down against the elastic body 223, causing the elastic body 223 to deform elastically, and the pressure rib can enter the slot. When the upper hook 221 passes the connecting hook 111 upward, the upper hook 221 is engaged with the connecting hook 111. Remove the external force on the connecting plate 220. The elastic body 223 can reduce the assembly gap at the connection between the lower hook 222 and the pressure rib, making the connection between the two tighter, and can provide downward elastic pressure on the connecting plate 220, making the engagement between the upper hook 221 and the connecting hook 111 more stable.

[0032] To further reduce air convection between the two movable fans, in this embodiment, a downwardly extending partition 230 is connected to the bottom side of the baffle 210, and the partition 230 is spaced apart from the connecting plate 220. In use, the partition 230 is located between the two movable fans. Even if airflow passes through the movable gap between the front guide rail 110 and the front movable fan to the position of the baffle 210, the airflow can be blocked by the baffle 210, reducing the amount of airflow entering the rear movable fan or flowing into the installation area 130 through the clearance gap 140. Furthermore, the partition 230 between the two movable fans also further stabilizes their positions.

[0033] In some embodiments, the partition 230 is provided with first wool strip grooves 231 on its front and rear sides respectively. In use, wool strips can be inserted into the two first wool strip grooves 231, so that the two wool strips abut against the front and rear movable fans respectively, thereby improving the sealing between the partition 230 and the front and rear movable fans 320.

[0034] Similarly, a second wool strip groove 121 is provided on the front side of the rear guide rail 120. In use, wool strips can be inserted into the second wool strip groove 121, and the wool strips abut against the transmission plate 420, which can effectively reduce the airflow from the movable gap between the rear guide rail 120 and the transmission plate 420 into the installation area 130, and further improve the sealing performance during use.

[0035] like Figure 2 As shown, a sliding door / window includes a front movable sash 310, a rear movable sash 320, and the aforementioned window frame profile. The front guide rail 110 extends into the top of the front movable sash 310, and the rear guide rail 120 extends into the top of the rear movable sash 320. A drive unit 410 is provided on the bottom side of the upper frame 100 at the position of the installation area 130. The drive unit 410 is driveably connected to a transmission plate 420, and the drive unit 410 can drive the transmission plate 420 to move left and right. The transmission plate 420 passes through the clearance gap 140 and is connected to the rear movable sash 320. The movable fan 320 is connected, and the driver 410 is mainly used to provide the driving force for the transmission plate 420 to reciprocate in a straight direction. There are various structural forms. For example, the driver 410 includes a motor mounted on the upper frame 100, a transmission wheel connected to the motor, and a transmission belt connected to the transmission wheel. The transmission plate 420 is connected to one side of the transmission belt. The motor can drive the transmission wheel to rotate, and the transmission wheel drives the transmission belt to rotate. The transmission plate 420 is connected to the transmission belt. With the forward and reverse rotation of the motor, it can drive the transmission plate to move to the left or right.

[0036] During installation, the upper frame 100 is positioned above the external movable sash. The front guide rail 110 and the rear guide rail 120 respectively limit the top positions of the front movable sash 310 and the rear movable sash 320, improving the stability of the left and right movement of the front movable sash 310 and the rear movable sash 320. The driver 410 is installed in the installation area 130 formed between the front guide rail 110 and the rear guide rail 120. At this time, the baffle can cover part of the installation area 130, leaving only the clearance 140 formed between the baffle and the rear guide rail 120 for the transmission plate 420 and the rear movable sash 320 to make transmission connection. This can effectively reduce the convection of indoor and outdoor air through the installation area 130, thereby improving the airtightness of the window frame profile. In this way, by partially covering the area where electrical components are installed on the upper frame 100 through the baffle, the heat insulation and airtightness of the sliding door and window are improved, and the noise problem when the wind pressure is high is effectively reduced, improving the comfort of use.

[0037] In some embodiments, a first adhesive strip groove 311 is provided on the rear top side of the front movable fan 310 corresponding to the position of the baffle frame. An adhesive strip can be inserted into the first adhesive strip groove 311, and the adhesive strip abuts against one side of the baffle frame, that is, against the connecting plate 220. In this way, the movable gap between the front movable fan 310 and the connecting plate 220 can be blocked, effectively reducing the amount of air entering the movable gap between the front movable fan 310 and the baffle frame.

[0038] Similarly, a second adhesive strip groove 321 is provided on the top of the rear movable fan 320 corresponding to the position of the transmission plate 420. In use, an adhesive strip can be inserted into the second adhesive strip groove 321, and the adhesive strip abuts against the transmission plate 420 passing through the clearance gap 140, thereby reducing the movement gap between the rear movable fan 320 and the transmission plate 420 and further improving the overall airtightness.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
