[0001] This utility model relates to the technical field of building hardware and door and window accessories, and in particular to an easy-to-install aluminum alloy door and window sliding rail. Background Technology

[0002] In the installation of aluminum alloy doors and windows, the sliding rail plays a crucial supporting and guiding role as a key component. For modern buildings, the installation efficiency and operational stability of the sliding rail are particularly important, as they not only affect the opening and closing performance of doors and windows but also directly relate to the overall structural sealing and aesthetics. Due to the diverse applications of aluminum alloy doors and windows, their installation process needs to balance convenience and precision, thus placing higher demands on the design of the sliding rail. Currently, common sliding rail installation methods mostly rely on bolt fixing or embedded structures. While these methods can meet basic functional requirements, in practice, they often require numerous adjustments to ensure levelness and stability, making installation time-consuming and demanding on the technical skills of the installers. Furthermore, some sliding rails are prone to loosening or abnormal noise after long-term use, which also negatively impacts the user experience. Utility Model Content

[0019] This utility model provides an easy-to-install aluminum alloy door and window sliding track, the specific implementation of which is described in conjunction with the attached... Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1As shown, the base guide rail 1 has a long strip structure with a guide groove 4 at its top. Multiple slots 5 are evenly distributed on the inner walls of both sides of the guide groove 4. These slots 5 are used to engage with the positioning blocks 6 on the movable bracket 2 for quick positioning. The bottom of the base guide rail 1 has multiple mounting holes, into which expansion sleeves 9 are embedded. The outer wall of the expansion sleeve 9 fits tightly against the mounting hole, and the inner wall is threaded for use with fastening screws to fix it to the wall. The bottom surface of the base guide rail 1 also has multiple grooves, into which magnetic sheets are embedded. These magnetic sheets are used to attract metal tools or auxiliary installation equipment.

[0020] The movable bracket 2 slides into the guide groove 4 via a slider at its bottom. A ball bearing 10 is mounted on the slider, contacting the inner wall of the guide groove 4 to reduce sliding resistance. A dust cover is fitted around the outer ring of the ball bearing 10, and this dust cover is connected to the slider via a snap-fit ​​to prevent dust from entering. The top of the movable bracket 2 has connection holes for installing doors and windows. A removable cover plate surrounds these holes, and a rubber pad is installed on the inside of the cover plate to increase friction with the doors and windows, preventing them from wobbling during sliding. Indicator lines made of fluorescent material are installed on the side walls of the movable bracket 2, emitting a faint glow in low-light conditions to facilitate nighttime construction.

[0021] like Figure 2 As shown, a positioning block 6 is provided on the side wall of the movable support 2, and the positioning block 6 is connected to the movable support 2 through an elastic element 7. The elastic element 7 is a coil spring, one end of which is fixedly connected to the positioning block 6, and the other end is fixedly connected to the side wall of the movable support 2. A protective sleeve is provided on the outside of the coil spring to prevent dust from entering the interior of the coil spring. The end of the positioning block 6 is provided with a protrusion, and the end of the protrusion has a tapered slope. The tapered slope can automatically squeeze the edge of the slot 5 when the movable support 2 moves, causing the positioning block 6 to retract inward and disengage from the slot 5. When the movable support 2 moves to the appropriate position, the positioning block 6 is inserted into the slot 5 under the action of the elastic element 7, thereby realizing the rapid positioning of the movable support 2.

[0022] Both ends of the base guide rail 1 are fixed with end caps 3, which are connected to the base guide rail 1 by snap-fit. A buffer pad 8 is provided on the inner side of the end cap 3, such as... Figure 3 As shown, the surface of the buffer pad 8 has a wavy texture, which reduces the impact and noise when the door or window slides. The buffer pad 8 is made of silicone, and multiple micro-airbags are embedded inside the silicone. These micro-airbags can generate slight compression deformation when the door or window slides, thereby absorbing the impact and reducing noise. A decorative panel is provided on the outer side of the end cap 3. The surface of the decorative panel is coated with a scratch-resistant coating to improve aesthetics and durability.

[0023] A lubricating strip 11 is installed in the guide groove 4 of the basic guide rail 1. The lubricating strip 11 is made of polytetrafluoroethylene (PTFE), which has self-lubricating properties and can reduce the friction between the slider and the guide groove 4. The lubricating strip 11 is fixed to the bottom of the guide groove 4 by double-sided tape. The adhesive layer of the double-sided tape has been specially treated to maintain stable performance in high-temperature environments.

[0024] In actual installation, the base guide rail 1 is first fixed to the wall using expansion sleeves 9 and fastening screws. The threaded design of the expansion sleeves 9 effectively prevents the fastening screws from loosening. After installation, the slider of the movable bracket 2 is inserted into the guide groove 4. The ball bearings 10 on the slider contact the inner wall of the guide groove 4, reducing sliding resistance. When the movable bracket 2 slides along the guide groove 4, the protruding end of the positioning block 6 automatically presses against the edge of the slot 5 through the tapered inclined surface, causing the positioning block 6 to retract inward and disengage from the slot 5. When the movable bracket 2 moves to the appropriate position, the positioning block 6 is inserted into the slot 5 under the action of the elastic element 7, thereby achieving rapid positioning of the movable bracket 2. The top of the movable bracket 2 is connected to the door and window through the connecting hole. The rubber pad on the inside of the cover plate increases the friction between the bracket and the door and window, preventing the door and window from shaking during sliding.

[0025] During the sliding process of the doors and windows, the buffer pad 8 on the inner side of the end cap 3 absorbs impact and reduces noise through its wave-shaped texture and micro-airbag design. The magnetic sheet at the bottom of the base guide rail 1 can attract metal tools or auxiliary equipment, improving the convenience of the installation process. The lubrication strip 11 in the guide groove 4 is made of polytetrafluoroethylene, which has good self-lubricating properties, further reducing the friction between the slider and the guide groove 4 and extending the service life of the slide rail. The indicator marks on the side wall of the movable bracket 2 are made of fluorescent material, which can emit a faint light in low-light environments, making it easy for construction personnel to quickly adjust the installation position of the doors and windows.

[0026] This utility model achieves convenient installation and stable use of aluminum alloy door and window sliding rails through the above specific embodiments, solving the tedious steps that require repeated adjustments in traditional installation methods, while improving the user experience.

[0027] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further explained below in conjunction with a specific application scenario.

[0028] In the actual installation of aluminum alloy door and window sliding rails, the base rail 1 is first fixed to the wall using expansion sleeves 9 and fastening screws. The outer wall of the expansion sleeve 9 fits tightly against the mounting holes at the bottom of the base rail 1, and the threads on its inner wall effectively prevent the fastening screws from loosening. The key to this step is to utilize the structural characteristics of the expansion sleeve 9 to ensure the stability of the connection between the base rail 1 and the wall, thereby avoiding loosening problems that may occur during long-term use. Simultaneously, the magnetic sheet embedded in the bottom surface of the base rail 1 can attract metal tools or auxiliary equipment, improving the convenience of the construction process.

[0029] Subsequently, the movable bracket 2 is inserted into the guide groove 4 at the top of the base guide rail 1 via the bottom slider. The ball bearing 10 mounted on the slider contacts the inner wall of the guide groove 4. Due to the rolling friction characteristics of the ball bearing 10, the sliding resistance is significantly reduced. The dust cover on the outer ring of the ball bearing 10 is connected to the slider via a snap-fit, effectively preventing dust from entering and thus extending the service life of the slider. When the movable bracket 2 slides along the guide groove 4, the protruding end of the positioning block 6 automatically presses against the edge of the slot 5 through the tapered inclined surface, causing the positioning block 6 to retract inward and disengage from the slot 5. When the movable bracket 2 moves to the appropriate position, the positioning block 6 pops out under the action of the elastic element 7 and inserts into the slot 5, achieving rapid positioning. The principle of this process lies in the tapered inclined surface design of the positioning block 6, which can automatically complete the disengagement and relocking action during movement without additional adjustment, significantly improving installation efficiency.

[0030] The doors and windows are installed through the connection holes at the top of the movable bracket 2. Rubber pads are installed on the inner side of the cover plates around the connection holes. The rubber pads increase the friction between the doors and windows and prevent them from shaking during sliding. The core of this design is to improve the stability of the doors and windows after installation by increasing friction, thereby avoiding abnormal noises or shaking caused by uneven sliding.

[0031] During the sliding process of doors and windows, the buffer pads 8 installed on the inner side of the end caps 3 at both ends of the base guide rail 1 play an important role. The wavy texture on the surface of the buffer pad 8 can disperse the impact force, while the micro airbags embedded inside it can further absorb the impact energy through compression and deformation, thereby reducing the noise generated during sliding. The principle of this design is to use the elasticity of silicone material and the compressibility of micro airbags to convert the impact force into deformation energy, thereby reducing noise and vibration.

[0032] Furthermore, the lubricating strip 11 installed in the guide groove 4 of the basic guide rail 1 is made of polytetrafluoroethylene (PTFE), which has self-lubricating properties and can reduce the friction between the slider and the guide groove 4. The lubricating strip 11 is fixed to the bottom of the guide groove 4 with double-sided tape, which is specially treated to maintain stable performance in high-temperature environments. The principle of this design is to reduce sliding resistance by using a material with a low coefficient of friction, thereby extending the service life of the slide rail and improving the smoothness of sliding.

[0033] The indicator lines on the side wall of the movable support 2 are made of fluorescent material, which emits a faint light in low-light environments, making it easier for construction workers to quickly determine the position of the movable support 2 and make adjustments. The principle of this design is to utilize the luminescent properties of fluorescent materials to facilitate construction at night or in low-light environments.

[0034] In summary, this utility model, through optimized structural design of the slide rail, achieves a stable connection between the basic guide rail 1 and the wall, rapid positioning of the movable bracket 2, and vibration and noise reduction during the sliding of doors and windows. These designs are all based on specific physical principles, such as the mechanical properties of the conical inclined plane, the restoring force of the elastic element, the elastic deformation of silicone, and the self-lubricating properties of polytetrafluoroethylene, thereby ensuring convenient installation and stable use of the slide rail. The implementation methods described above not only solve the problem of repeated adjustments required in traditional installation methods but also significantly improve the user experience.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are prior art, and will not be described further here.
