Description

Technical Field

[0001] The utility model relates to the technical field of sliding doors and windows, in particular to an upper rail connecting structure of sliding doors and windows. Background Art

[0002] Sliding doors and windows are a type of door and window widely used in the modern construction industry, named after the way they are opened. Sliding doors and windows are more convenient to open than traditional doors and windows, and have the advantages of being easy to open, not occupying indoor space, and being beautiful and elegant. Generally, a pulley is provided at the bottom of the sliding door and window, and a guide strip is provided on the lower track of the outer frame to cooperate with the door and window pulley, so that the sliding sash can slide in a straight line along the lower track guide strip. Although the bottom pulley and the guide strip cooperate to make the sliding sash smooth to reduce swinging, as the sliding sash becomes larger and larger, the height of the sliding sash is higher and the upper and lower distances are farther, it is difficult to prevent the top of the sliding sash from swinging by relying solely on the pulley and the guide strip at the bottom and the sealing strip on the outer frame. The top of the sliding sash will still swing, making the sliding sash vulnerable to damage, and will also cause the sliding sash to deviate from the guide strip and fail to close normally. In the prior art, a sealing and limiting structure for a sliding window with the publication (announcement) number CN205858124U discloses a movable sash window, wherein the movable sash window is provided with a limiting device, wherein the limiting device is arranged on the end face of the movable sash window, and the limiting device is arranged higher than the end face of the movable sash window; the limiting device has a card slot and a stopper, wherein the stopper is arranged close to the card slot, and the card slot is plugged with a sealing member. When the movable sash window is closed, the stopper contacts the sealing member of the card slot, thereby ensuring the normal closure of the sliding sash and improving its tightness. However, this structure can only produce a limiting effect in the closed state, that is, when the stopper and the card slot are combined. During the pushing and pulling process, the top of the sliding sash will still swing, and the problem of the top of the sliding sash swinging during the pushing and pulling process cannot be effectively solved.

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] As shown in the accompanying drawings, the utility model provides an upper rail connection structure for sliding doors and windows, including an upper rail profile 1 and a sliding fan 2. A pulley is provided at the bottom of the sliding fan 2, and a guide bar is provided in the lower rail profile at the bottom of the outer frame. The pulley slides linearly on the guide bar. This belongs to the basic structure of existing sliding doors and windows. A top profile 21 is provided at the top of the sliding fan 2, and the upper rail profile 1 includes a track groove 10. Figure 1 As shown, the track groove 10 is symmetrically provided with limiting ribs 11 on the front and rear side walls in the thickness direction of the push-pull fan 2. The two limiting ribs 11 are arranged horizontally, and the length of the limiting rib 11 is equal to the length of the upper rail profile 1, and the side where the two limiting ribs 11 are close to each other is set to be spherical. The top of the top profile 21 is symmetrically provided with two adapter profiles 22. The total width of the two adapter profiles 22 corresponds to the thickness of the top profile 21, and the two adapter profiles 22 have the same shape, which is more convenient for production. At the same time, the two adapter profiles 22 and the top profile 21 are split structures. The length of the two adapter profiles 22 is equal to the length of the top profile 21, which is convenient for installation. The two adapter profiles 22 are both rotatably connected. There is an anti-sway roller 23, and the transfer profile 22 has a profile inner cavity. The two anti-sway rollers 23 are respectively abutted against the two limiting ribs 11. The anti-sway roller 23 is rotatably set in the inner cavity of the transfer profile 22, and partially protrudes from the transfer profile 22 and is slidably connected to the limiting rib 11. As the sliding fan 2 moves, the anti-sway roller 23 slides on the limiting rib 11. At least one anti-sway roller 23 is set on a transfer profile 22, and preferably two or more are set. The two anti-sway rollers 23 are respectively located at the front and rear parts of the length direction of the transfer profile 22. In the static state, the anti-sway roller 23 abuts against the corresponding limiting rib 11. When people move the sliding fan 2, the anti-sway roller 23 slides on the limiting rib 11.

[0019] The present invention provides an upper rail connection structure for sliding doors and windows, which makes the sliding sash 2 and the upper rail profile 1 abut against each other through two limiting ribs 11 symmetrically arranged in the rail groove 10, which cooperate with the anti-sway roller 23 provided on the top profile 21, thereby preventing the top of the sliding sash 2 from shaking back and forth during the pushing and pulling process. That is, the top of the sliding sash 2 is positioned by the limiting rib 11 and the anti-sway roller 23, and the bottom is positioned by the pulley and the guide bar of the lower rail profile, which effectively solves the problem of the sliding sash 2 swinging during the pushing and pulling process, and the anti-sway roller 23 slides on the limiting rib 11 as the sliding sash 2 is pushed and pulled, ensuring smooth and stable pushing and pulling.

[0020] In this embodiment, two slide grooves 210 are provided on the top of the top profile 21, and slide plates 221 slidably connected to the slide grooves 210 are provided at the bottom of the two adapter profiles 22, which are convenient for installing and connecting the top profile 21 and the adapter profile 22. The adapter profile 22 is inserted into the slide groove 210 from the end of the slide groove 210 through the slide plate 221. At this time, the adapter profile 22 can slide on the top profile 21. Preferably, the length of the top profile 21 is equal to the length of the adapter profile 22. A fixing screw is provided between the bottom of the slide plate 221 and the slide groove 210. When the adapter profile 22 slides to the appropriate position, the adapter profile 22 is fixedly connected to the top profile 21 by the fixing screw.

[0021] In this embodiment, one side of the two transition profiles 22 is in contact with each other, and the other side is provided with an opening 220. The anti-sway roller 23 is horizontally arranged in the transition profile 22 and extends to the outside through the opening 220. When the two transition profiles 22 are installed on the top of the top profile 21, one side of the two transition profiles 22 is in contact with each other, and the anti-sway roller 23 is horizontally arranged in the inner cavity of the transition profile 22 and protrudes from the other side of the transition profile 22 through the opening 220. The protruding part of the anti-sway roller 23 is in contact with the limit The ribs 11 are offset against each other, and the middle part of the anti-sway roller 23 is rotatably connected to a rotating shaft 230, and is rotatably connected to the adapter profile 22 through the rotating shaft 230. A notch 222 for positioning and installing the rotating shaft 230 is provided on the top of the adapter profile 22. The rotating shaft 230 is installed on the adapter profile 22. The notch 222 on the top of the adapter profile 22 is mainly convenient for positioning and installing the rotating shaft 230. The rotating shaft 230 penetrates the inner cavity of the adapter profile 22 at the notch 222 and is connected to the bottom of the adapter profile 22 through the anti-sway roller 23. The two transition profiles 22 are in contact with each other on one side thereof, and a semicircular groove 223 is provided correspondingly, thereby forming a circular hole, and a connecting column 224 is provided in the circular hole. The two transition profiles 22 are positioned and installed by connecting the slide plate 221 and the slide groove 210. At this time, there is still a gap between the anti-sway roller 23 on the transition profile 22 and the limiting rib 11, and the connecting column 224 can be inserted into the circular hole, thereby spreading the two transition profiles 22 to both sides, and then making the anti-sway roller 23 press against the limiting rib 11. The distance between the two limit ribs 11 corresponds to each other, and generally they are adapted to each other. At the same time, the installation position of the rotating shaft 230 can be moved when installing the anti-sway roller 23, so that the anti-sway roller 23 can protrude or retract a certain distance to achieve the distance adapted to the limit rib 11. For example, the main purpose of setting the connecting column 224 is to further fix the two adapter profiles 22 on the top profile 21, and to stretch the two adapter profiles 22 apart, so that the anti-sway roller 23 and the limit rib 11 are more tightly connected.

[0022] In this embodiment, mounting portions 101 for mounting sealing strips are provided on both sides of the groove opening of the track groove 10. The mounting portion 101 and the limiting rib 11 are both provided on the same vertical plane. The sealing strip belongs to the structure on the existing sliding doors and windows. A sealing strip is provided on the outer frame to abut against the sliding fan 2 to form a sealed partition. The current sealing strip is made of soft plastic material, and when it abuts against the sliding fan 2, it will produce a certain compression deformation. Therefore, the limiting rib 11 corresponds to the mounting portion 101, so that a certain gap can be left between the mounting portion 101 and the sliding fan 2 to install the sealing strip, and a certain deformable space can be provided for the sealing strip.

[0023] During installation, the sliding fan 2 can be installed into the outer frame first. You can refer to the installation steps of existing sliding doors and windows. After the installation is completed, insert the adapter profile 22 from the end face of the sliding fan 2, and insert it into the corresponding slide groove 210 through its slide plate 221. At this time, the adapter profile 22 can slide in the top profile 21. Slide the adapter profile 22 to align with the top profile 21 of the sliding fan 2. At this time, the anti-sway roller 23 on the adapter profile 22 also abuts against the limiting rib 11. Fix the adapter profile 22 by inserting screws between the slide plate 221 and the slide groove 210 from the end face. If it is found that the abutment between the anti-sway roller 23 and the limiting rib 11 is not tight, the two adapter profiles 22 can be stretched apart by installing a connecting column 224 in the circular hole, so that the abutment between the anti-sway roller 23 and the limiting rib 11 is tighter.

[0024] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the scope of protection of the present invention.
