Description

Technical Field

[0001] This utility model relates to the technical field of sliding doors and windows, and in particular to a top and bottom horizontal profile and sliding doors and windows using the same. Background Technology

[0002] Currently, sliding doors and windows are a type of door and window structure that opens by sliding horizontally or vertically. They are widely used in residential and commercial applications. Sliding doors and windows consist of door panels, window frames, tracks, pulleys, and sealing strips. The door panel is surrounded by glass panels, hooks, upper horizontal rails, and lower horizontal rails. The upper and lower horizontal rails are the core load-bearing and connecting components of the sliding door and window system, serving as the upper guide rail base and lower load-bearing frame, respectively. They bear key functions such as glass fixing, pulley assembly, load transfer, and sealing protection. They are suitable for sliding doors and windows in residential and commercial buildings and are core components that ensure smooth opening and closing, structural stability, and durability. Currently, the upper and lower horizontal rails are usually locked with bolts when installing the pulleys. However, relying solely on bolt locking will cause the bolts to loosen over time, leading to instability in the pulleys. Utility Model Content

[0003] To address the aforementioned shortcomings, the purpose of this utility model is to propose an upper and lower horizontal profile and a sliding door and window using it, thereby solving the problem of existing pulleys becoming loose and unstable after long-term use.

[0004] To achieve this objective, the present invention adopts the following technical solution: A vertical profile includes a profile body, a cavity in the middle of the profile body, a glass fixing frame on one side of the profile body, the glass fixing frame being recessed toward the cavity, a glass slot on the outward side of the glass fixing frame, and a pulley fixing frame on the other side of the profile body. The pulley fixing frame includes two sets of fixing parts, two sets of mounting parts, and two sets of sealing parts; one end of each of the two sets of fixing parts is respectively disposed at both ends of the profile body, and the other end of the fixing part is connected to one end of the mounting part through a connecting part. The fixing part and the mounting part are parallel to each other, and the connecting part is perpendicularly connected to the fixing part and the mounting part respectively. The inner surface of the fixing part forms a sealing groove for installing a sealing strip; the other end of the mounting part is provided with a sealing part, and an installation opening is formed between the two sealing parts.

[0005] Preferably, the two sets of sealing parts are respectively disposed on the inner side of the two sets of mounting parts, and a mounting groove is provided on the opposite side of the sealing part, the mounting groove being a rectangular groove.

[0006] Preferably, the middle part of the mounting groove is recessed to both sides to provide limiting grooves.

[0007] Preferably, a bolt mounting seat is provided on one side of the profile body, the bolt mounting seat is disposed between the two sets of fixing parts, and a bolt mounting hole is provided in the middle of the bolt mounting seat.

[0008] Preferably, the glass fixing frame includes two sets of connecting sections and limiting sections. The two sets of connecting sections are symmetrically arranged at both ends of the profile body. The two ends of the limiting sections are respectively connected to the other ends of the two sets of connecting sections. The distance b between the two sets of connecting sections is 13.9-14.1cm.

[0009] Preferably, an extension strip is provided on the opposite side of the outer ends of the two sets of connecting segments. The extension strip is perpendicular to the connecting segment, and the distance d between the extension strips is 9.9-10.1cm.

[0010] Preferably, the middle part of the limiting segment is provided with an arc-shaped groove, and the cross-section of the arc-shaped groove is semi-circular.

[0011] Preferably, the depth h of the arc-shaped groove is 0.2-0.3 mm.

[0012] This application also proposes a sliding door / window that utilizes the aforementioned upper and lower horizontal profiles.

[0013] One of the above technical solutions has the following advantages or beneficial effects: The upper and lower horizontal profiles are used to fix the glass frame for installation, while the pulley fixing frame is used to install the pulley that slides with the window frame. The other end of the fixing part is connected to one end of the mounting part through the connecting part, so that the inner side of the fixing part forms a groove. When installing the pulley, a sealing strip can be set in the sealing groove to limit and fix the pulley. The outer frame of the pulley squeezes the sealing strip, and the elastic deformation reaction force of the sealing strip limits and fixes the pulley, ensuring the stability of the pulley. At the same time, it is also easier to disassemble, avoiding the situation where the bolts will loosen after long-term use due to bolt locking alone, which will lead to the instability of the pulley.

[0019] The following is combined with Figures 1 to 4This invention describes an upper and lower horizontal profile and a sliding door and window using the same. The upper and lower horizontal profile includes a profile body 1, a cavity 100 is provided in the middle of the profile body 1, a glass fixing frame 2 is provided on one side of the profile body 1, the glass fixing frame 2 is recessed towards the cavity 100, a glass slot 200 is provided on the outward side of the glass fixing frame 2, and a pulley fixing frame 3 is provided on the other side of the profile body 1. The pulley fixing frame 3 includes two sets of fixing parts 31, two sets of mounting parts 32, and two sets of sealing parts 33. One end of each of the two sets of fixing parts 31 is respectively disposed at both ends of the profile body 1. The other end of each fixing part 31 is connected to one end of each mounting part 32 through a connecting part 34. The fixing parts 31 and the mounting parts 32 are parallel to each other. The connecting part 34 is perpendicularly connected to the fixing parts 31 and the mounting parts 32 respectively. A sealing groove 310 for installing a sealing strip is formed on the inner side of the fixing part 31. The other end of each mounting part 32 is provided with a sealing part 33, and an installation opening 300 is formed between the two sealing parts 33.

[0020] The upper and lower horizontal profiles of the sliding door and window sash are used to install above and below the glass. In this embodiment, a cavity 100 is set in the middle of the profile body 1. While reducing the overall material usage of the profile and lowering production and transportation costs, the hollow structure of the cavity 100 can disperse external forces, improve the profile's resistance to bending and deformation, and avoid structural damage caused by uneven stress during long-term use, thus balancing lightweight and structural stability. The glass fixing frame 2 is used to install the glass, and the pulley fixing frame 3 is used to install the pulley that slides with the window frame. The other end of the fixing part 31 is connected to one end of the mounting part 32 through the connecting part 34, so that the inner side of the fixing part 31 forms a groove. When installing the pulley, a sealing strip can be set in the sealing groove 310 to limit and fix the pulley. The outer frame of the pulley squeezes the sealing strip, and the elastic deformation reaction force of the sealing strip limits and fixes the pulley, ensuring the stability of the pulley. At the same time, disassembly is also more convenient, avoiding the situation where the bolts will loosen and cause the pulley to become unstable after long-term use if only bolt locking is used. The recessed glass fixing frame 2 has a glass slot 200, which allows the glass to be quickly embedded and positioned during installation, avoiding installation misalignment. The glass slot 200 can precisely limit the edge of the glass, and the glass can be fixed without the need for additional positioning parts, reducing assembly steps and improving the glass installation efficiency in scenarios such as doors and windows, while avoiding the risk of shaking or breakage caused by loose glass.

[0021] Furthermore, the two sets of sealing parts 33 are respectively disposed on the inner side of the two sets of mounting parts 32, and a mounting groove 330 is provided on the opposite side of the sealing part 33, the mounting groove 330 being a rectangular groove.

[0022] Specifically, the function of the mounting groove 330 is to provide an installation reference for the installation of the sealing strip, reducing the difficulty of assembly and improving the convenience of assembly and subsequent maintenance. The main function of the sealing strip is to prevent dust, rainwater and other debris from entering the pulley fixing frame 3, thereby protecting the pulley. The rectangular mounting groove 330, through the "encircling constraint" of the groove wall, restricts the vertical movement of the strip by the upper and lower groove walls and restricts the horizontal displacement by the side groove walls, which can firmly fix the sealing strip in the preset position, preventing the strip from falling off or shifting due to friction and vibration during the sliding of doors and windows, and ensuring the long-term stability of the sealing effect.

[0023] Furthermore, the middle part of the mounting groove 330 is recessed to both sides to provide limiting grooves 331.

[0024] Specifically, the limiting groove 331 is provided on the upper and lower side walls of the mounting groove 330. The cross-section of the sealing strip is usually designed with a protrusion that matches the slot, or it can fit the recessed limiting groove 331 through its own elastic deformation. The shape of the recessed limiting groove 331 can form a "protrusion-recession" interlocking relationship with the strip, so that after the strip is embedded in the mounting groove 330, its corresponding position will be locked into the limiting groove 331. This is equivalent to adding a "buckle structure" in the middle of the mounting groove 330, which effectively prevents the strip from coming out along the opening direction of the mounting groove 330.

[0025] Furthermore, a bolt mounting seat 4 is provided on one side of the profile body 1, the bolt mounting seat 4 is disposed between the two sets of fixing parts 31, and a bolt mounting hole 400 is provided in the middle of the bolt mounting seat 4.

[0026] Specifically, the bolt mounting holes 400 provide preset assembly positions for the bolts, avoiding positioning deviations caused by on-site drilling, ensuring accurate connection positions between the profiles and external components (such as door and window vertical frames), thereby ensuring the squareness of the overall door and window frame and avoiding problems such as uneven glass installation gaps and pulley slippage caused by connection deviations.

[0027] Furthermore, the glass fixing frame 2 includes two sets of connecting sections 21 and limiting sections 22. The two sets of connecting sections 21 are symmetrically arranged at both ends of the profile body 1, and the two ends of the limiting sections 22 are respectively connected to the other ends of the two sets of connecting sections 21. The distance b between the two sets of connecting sections is 13.9-14.1cm.

[0028] Specifically, the two sets of connecting sections 21 and limiting sections 22 form a surrounding positioning structure. Together, they constitute a glass slot 200 with a "U-shaped constraint space". This can firmly fix the glass within the glass slot 200, preventing the glass from moving along the length direction (left and right) or thickness direction (inside and outside) when the door and window are pushed, pulled or vibrated. This prevents the glass from colliding with the glass slot 200 and causing damage, or causing sealing gaps due to displacement. The spacing range of 13.9-14.1cm precisely matches the "glass + sealing strip" combination specifications commonly used in the door and window industry. This spacing ensures that after the glass is embedded in the glass slot 200, the sealing strip can be evenly squeezed to fill the gap. It will not cause the glass to shake due to excessive spacing, nor will it cause the glass to be excessively squeezed due to excessive spacing.

[0029] Furthermore, an extension strip 23 is provided on the opposite side of the outer ends of the two sets of connecting segments 21. The extension strip 23 is arranged perpendicular to the connecting segment 21, and the distance d between the extension strips 23 is 9.9-10.1cm.

[0030] Specifically, extension strips 23 are provided on both sides of the opening of the glass slot 200. When installing glass, they can cooperate with the glass to form a filling groove. By filling and sealing the strip, the glass can be stabilized. It can adapt to different glass thicknesses, so the installation stability is not affected. At the same time, it is very simple to operate, and when not in use, it can also ensure the integrity of the light fixture and its aesthetics are not affected. The spacing range of 9.9-10.1cm can match the installation size of thinner doors and windows.

[0031] Furthermore, an arc-shaped groove 221 is provided in the middle of the limiting segment 22, and the cross-section of the arc-shaped groove 221 is semi-circular.

[0032] Specifically, the arc-shaped groove 221 helps with water drainage, preventing water accumulation from affecting the stability of the glass, especially in outdoor or humid environments, reducing the risk of the glass getting damp. Moreover, the arc-shaped groove 221 can increase the moment of inertia of the limiting section 22, preventing stress concentration from causing deformation or damage to the limiting section 22, and improving the bending and torsional resistance of the glass fixing frame 2.

[0033] Furthermore, the depth h of the arc-shaped groove 221 is 0.2 to 0.3 mm.

[0034] In one specific embodiment of this utility model, the depth h of the arc-shaped groove 221 is 0.2mm, which can just avoid stress concentration causing deformation or damage to the limiting section 22, improve the bending and torsional resistance of the glass fixing frame 2, and avoid excessive depth affecting the rigidity of the limiting section 22.

[0035] Furthermore, this application also proposes a sliding door / window that utilizes the aforementioned upper and lower horizontal profiles.

[0036] Sliding doors and windows constructed using glass sashes fixedly installed with these upper and lower horizontal profiles maintain stability and reliability even after long-term use, resulting in a longer service life.

[0037] The upper and lower horizontal profiles according to the present utility model, as well as other components and operations of sliding doors and windows using the same, are known to those skilled in the art and will not be described in detail here.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
