Description

Technical Field

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

[0002] As an important component of buildings, doors and windows play a core role in separating spaces, providing lighting and ventilation, thermal insulation, security and protection, and decorative aesthetics. Doors and windows are mainly divided into two types: sliding doors and double doors.

[0003] Existing sliding windows are generally composed of two glass frames, and ventilation can only be achieved by moving one of the glass frames. The function is relatively simple. Although it saves more space compared to double-opening windows, the ventilation area is smaller and cannot be used according to specific needs. Therefore, we continue to improve the structure of existing doors and windows. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a sliding aluminum alloy door and window.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sliding aluminum alloy door and window, including a mounting frame and two sets of glass frames disposed within the mounting frame. Each mounting frame has a sliding groove, and each mounting frame has a limiting groove communicating with the sliding groove at a position corresponding to the two sets of glass frames. The two sliding grooves are respectively disposed on the inner top wall and inner bottom wall of the mounting frame. A sliding block is fixed on each glass frame and slides in cooperation with the limiting groove. A positioning rod is provided through the sliding block and cooperates with it. A positioning through hole is provided through the mounting frame for the positioning rod to pass through and cooperate with it. A lifting mechanism is provided on the glass frame for driving the positioning rod to rise and fall. The number of sliding blocks, the number of limiting grooves, the number of positioning rods, and the number of positioning through holes are all equal and their positions correspond one-to-one. The number of lifting mechanisms is equal to the number of glass frames and their positions correspond one-to-one.

[0006] By adopting the above technical solution, the operator first lowers the positioning rod using the lifting mechanism to separate it from the positioning through hole. Then, the glass frame is pulled, causing the sliding block to move until it moves from the limiting groove to the sliding groove. Finally, the glass frame is pushed towards another glass frame until it can no longer move, thus achieving ventilation on both sides of the installation frame. Furthermore, because the positioning rod is inserted through and engages with the sliding block, and the positioning through hole allows the positioning rod to pass through and engage, both sets of glass frames can be directly rotated. The two sets of positioning rods will move within the sliding block and positioning through hole until the two sets of glass frames can no longer rotate, thereby increasing the ventilation area on both sides of the installation frame. This product can be used according to specific needs, increasing the functionality of doors and windows.

[0007] Furthermore, the lifting mechanism includes a positioning component, which includes a rotating connecting plate rotatably mounted inside the glass frame, a vertical rod rotatably mounted on the end of the rotating connecting plate away from the positioning rod, and a fixing block fixed inside the glass frame. The rotating connecting plate is rotatably connected to the positioning rod, and the vertical rod passes through the fixing block and is slidably engaged. The lifting mechanism also includes a lifting component for driving the vertical rod to rise and fall.

[0008] By adopting the above technical solution, the vertical rod is driven to rise by the lifting component. Since the vertical rod is rotatably connected to the rotating connecting plate and the rotating connecting plate is rotatably installed inside the glass frame, the end of the rotating connecting plate away from the positioning rod flips upward, while the end of the positioning component close to the positioning rod flips downward, causing the positioning rod to descend until the positioning rod separates from the positioning through hole, thus ensuring the normal use of the doors and windows.

[0009] Furthermore, the lifting assembly includes a limiting block fixed to the vertical rod and located below the fixed block, a return spring fixed between the limiting block and the fixed block, a rotating rod that passes through and is rotatably connected to the glass frame, a lifting block fixedly sleeved on the rotating rod and located inside the glass frame, and an arc block fixed to the side wall of the lifting block. The distance between the side wall of the arc block away from the lifting block and the axis of the lifting block gradually decreases from the middle of the arc block to both sides.

[0010] By adopting the above technical solution, the rotating rod drives the lifting block to rotate 90 degrees. The arc block rotates and approaches the vertical rod until the middle of the side wall of the arc block away from the lifting block abuts against the vertical rod. Since the distance between the side wall of the arc block away from the lifting block and the axis of the lifting block gradually decreases from the middle of the arc block to both sides, the vertical rod gradually rises during this process, thereby achieving the purpose of separating the positioning rod from the positioning through hole.

[0011] Furthermore, a locking mechanism is provided on both the mounting frame and the glass frame. The locking mechanism includes a connecting rod slidably mounted on the lifting block, a locking block rotatably mounted on the connecting rod, and a vertical plate fixed in the mounting frame and located between the two sets of glass frames. The locking block passes through the glass frame and is slidably engaged. A limiting through hole is provided on the vertical plate to engage with the locking block. An adjustment groove is provided on the lifting block and is eccentrically positioned. The connecting rod is slidably engaged with the adjustment groove.

[0012] By adopting the above technical solution, the rotating rod rotates forty-five degrees. During this process, due to the eccentric setting of the rotating rod and the adjusting groove, the adjusting groove and the connecting rod are slidably connected. The connecting rod drives the locking block to move away from the vertical plate until the locking block separates from the limiting through hole. At this time, the glass frame can be rotated, and the purpose of ventilation on both sides of the installation frame can be achieved. The setting of the locking mechanism improves the stability when the glass frame is connected to the installation frame.

[0013] Furthermore, an auxiliary mechanism is provided on both the glass frame and the rotating rod. The auxiliary mechanism includes an auxiliary component, which includes a movable connecting plate fixed to the rotating rod and coaxially arranged with the rotating rod, a handle fixed to the movable connecting plate, and a limiting tube fixed to the glass frame and coaxially arranged with the movable connecting plate. The movable connecting plate and the limiting tube are rotatably connected. The auxiliary mechanism also includes a limiting component for limiting the handle.

[0014] By adopting the above technical solution, rotating the handle drives the movable connecting plate to rotate, which in turn drives the rotating rod to rotate, thereby ensuring the normal use of the device.

[0015] Furthermore, an installation groove is provided on the inner wall of the handle. The limiting component includes a movable block slidably disposed in the installation groove, a limiting spring fixed between the movable block and the inner wall of the installation groove, and a locking block fixed on the movable block and having an L-shaped structure. The horizontal section of the locking block penetrates the side wall of the handle near the movable connecting plate and is slidably engaged. The horizontal section of the locking block penetrates the movable connecting plate and is slidably engaged. A limiting groove is provided on the inner wall of the limiting tube. An arc groove communicating with the limiting groove is provided on the inner wall of the limiting tube. The vertical section of the locking block is slidably engaged with the arc groove. There are three arc grooves.

[0016] By adopting the above technical solution, firstly, the movable block is moved away from the mounting frame, and the limiting spring gradually contracts. The locking block moves from the limiting groove to the arc groove. At this time, the handle is rotated, causing the locking block connected to the handle to rotate until it moves to the position of the middle arc groove. Then, the movable block is released, and the limiting spring gradually extends. Both the movable block and the locking block move towards the mounting frame until the locking block slides into the arc groove. At this point, the locking block separates from the limiting through hole, allowing the glass frame to rotate. Similarly, the locking block is separated from the middle arc groove, and the handle is rotated until the locking block moves to the position of another arc groove. The locking block is then connected to the arc groove. At this point, the positioning rod separates from the positioning through hole, allowing the glass frame to slide. The setting of the limiting component improves the stability of the rotating rod when it is stationary.

[0017] Furthermore, rollers that are rotatably mounted on the vertical rod and are in rolling connection with the lifting block are also mounted on it.

[0018] By adopting the above technical solution, the roller configuration reduces the friction between the vertical rod and the lifting block.

[0019] Furthermore, a limiting rod is fixed inside the glass frame, and the limiting rod passes through the locking block and slides in engagement with it.

[0020] By adopting the above technical solution, the setting of the limit rod improves the stability of the locking block during movement.

[0021] In summary, this utility model has the following beneficial effects: In this application, by improving the structure of the prior art, this product can be used according to specific needs, thus increasing the functionality of doors and windows. Attached Figure Description

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] like Figure 1-10As shown in the figure, this application discloses a sliding aluminum alloy door and window, including a mounting frame 1, a glass frame 2, a lifting mechanism 8, a locking mechanism 9, and an auxiliary mechanism 10. The glass frame 2 is disposed within the mounting frame 1 and is used for the installation of transparent glass. Two sets of glass frames 2 are provided and symmetrically arranged about the middle of the mounting frame 1. Each set of the mounting frame 1 has a sliding groove 3. A limiting groove 4 communicating with the sliding groove 3 is provided on the mounting frame 1 at a position corresponding to the two sets of glass frames 2. The two sliding grooves 3 are respectively disposed on the inner top wall and inner bottom wall of the mounting frame 1. A sliding block 5 is fixed on the glass frame 2 and slides with the limiting groove 4. A positioning rod 6 that cooperates with the sliding block 5 is provided through the sliding block 5. A positioning through hole 7 is provided through the mounting frame 1 for the positioning rod 6 to pass through and cooperate. The number of sliding blocks 5, the number of limiting grooves 4, the number of positioning rods 6, and the number of positioning through holes 7 are all equal and their positions correspond one-to-one. First, the operator lowers the positioning rod 6 using the lifting mechanism 8, separating it from the positioning through hole 7. Then, the glass frame 2 is pulled, causing the sliding block 5 to move from the limiting groove 4 into the sliding groove 3. Finally, the glass frame 2 is pushed towards another glass frame 2 until it can no longer move, thus achieving ventilation on both sides of the installation frame 1. Furthermore, since the positioning rod 6 is inserted through and engages with the sliding block 5, and the positioning through hole 7 allows the positioning rod 6 to pass through and engage, both sets of glass frames 2 can be directly rotated. The two sets of positioning rods 6 will move within the sliding block 5 and the positioning through hole 7 until the two sets of glass frames 2 can no longer rotate, thereby increasing the ventilation area on both sides of the installation frame 1. This product can be used according to specific needs, increasing the functionality of doors and windows.

[0035] A lifting mechanism 8 is mounted on the glass frame 2 and is used to drive the positioning rod 6 to rise and fall. The number of lifting mechanisms 8 is equal to the number of glass frames 2, and their positions correspond one-to-one. The lifting mechanism 8 includes a positioning component 81 and a lifting component 82. The positioning component 81 includes a rotating connecting plate 811, a vertical rod 812, and a fixing block 813. The rotating connecting plate 811 is rotatably mounted inside the glass frame 2 and is rotatably connected to the positioning rod 6. The vertical rod 812 is rotatably mounted on the end of the rotating connecting plate 811 away from the positioning rod 6. The vertical rod 812 passes through the fixing block 813 and is slidably engaged. The fixing block 813 is fixed inside the glass frame 2. The lifting assembly 82 drives the vertical rod 812 to rise. Since the vertical rod 812 is rotatably connected to the rotating connecting plate 811, and the rotating connecting plate 811 is rotatably installed inside the glass frame 2, the end of the rotating connecting plate 811 away from the positioning rod 6 flips upward, while the end of the positioning assembly 81 close to the positioning rod 6 flips downward, causing the positioning rod 6 to descend until the positioning rod 6 separates from the positioning through hole 7, so as to ensure the normal use of the door and window.

[0036] The lifting assembly 82 is used to drive the vertical rod 812 to rise and fall. The lifting assembly 82 includes a limiting block 821, a return spring 822, a rotating rod 823, a lifting block 824, and an arc block 825. The limiting block 821 is fixed to the vertical rod 812 and located below the fixed block 813. The return spring 822 is fixed between the limiting block 821 and the fixed block 813. The rotating rod 823 passes through and is rotatably connected to the glass frame 2. The lifting block 824 is fixedly sleeved on the rotating rod 823 and located inside the glass frame 2. The arc block 825 is fixed to the side wall of the lifting block 824. The distance between the side wall of the arc block 825 away from the lifting block 824 and the axis of the lifting block 824 gradually decreases from the middle of the arc block 825 to both sides. Rotating the rotating rod 823 causes the lifting block 824 to rotate 90 degrees. The arc block 825 rotates and approaches the vertical rod 812 until the middle of the side wall of the arc block 825 away from the lifting block 824 abuts against the vertical rod 812. Since the distance between the side wall of the arc block 825 away from the lifting block 824 and the axis of the lifting block 824 gradually decreases from the middle of the arc block 825 to both sides, the vertical rod 812 gradually rises during this process, thereby achieving the purpose of separating the positioning rod 6 from the positioning through hole 7.

[0037] A locking mechanism 9 is jointly mounted on the mounting frame 1 and the glass frame 2. The locking mechanism 9 includes a connecting rod 91, a locking block 92, and a vertical plate 93. The connecting rod 91 is slidably mounted on the lifting block 824, and the locking block 92 is rotatably mounted on the connecting rod 91. The locking block 92 passes through the glass frame 2 and is slidably engaged. The vertical plate 93 is fixed inside the mounting frame 1 and located between the two sets of glass frames 2. A limiting through hole 95 is provided on the vertical plate 93 to engage with the locking block 92. An adjusting groove 96 is provided on the lifting block 824 and is eccentrically positioned thereon. The connecting rod 91 is slidably engaged with the adjusting groove 96. Rotating rod 823 rotates forty-five degrees. During this process, due to the eccentric setting of rotating rod 823 and adjusting groove 96, adjusting groove 96 is slidably connected to connecting rod 91. Connecting rod 91 drives locking block 92 to move away from vertical plate 93 until locking block 92 separates from limiting through hole 95. At this time, glass frame 2 can be rotated, and ventilation on both sides of mounting frame 1 can be achieved. The setting of locking mechanism 9 improves the stability when glass frame 2 is connected to mounting frame 1.

[0038] Auxiliary mechanism 10 is jointly mounted on glass frame 2 and rotating rod 823. Auxiliary mechanism 10 includes auxiliary component 101 and limiting component 102. Auxiliary component 101 includes movable connecting plate 1011, handle 1012, and locking block 1023. Movable connecting plate 1011 is fixed to rotating rod 823 and coaxially arranged with rotating rod 823. Movable connecting plate 1011 is rotatably connected to limiting tube 1013, and handle 1012 is fixed to movable connecting plate 1011. Mounting groove 11 is provided on the inner side wall of handle 1012. Limiting tube 1013 is fixed to glass frame 2 and coaxially arranged with movable connecting plate 1011. Limiting groove 12 is provided on the inner side wall of limiting tube 1013. Three arc grooves 13 are provided on the inner side wall of limiting tube 1013, which communicate with limiting groove 12. Rotating the handle 1012 causes the movable connecting plate 1011 to rotate, which in turn drives the rotating rod 823 to rotate, thus ensuring the normal use of the device.

[0039] The limiting component 102 is used to limit the handle 1012. The limiting component 102 includes a movable block 1021, a limiting spring 1022, and a locking block 1023. The movable block 1021 is slidably disposed in the mounting groove 11, and the limiting spring 1022 is fixed between the movable block 1021 and the inner sidewall of the mounting groove 11. The locking block 1023 is fixed to the movable block 1021 and has an L-shaped structure. The horizontal section of the locking block 1023 penetrates the sidewall of the handle 1012 near the movable connecting plate 1011 and is slidably engaged. The horizontal section of the locking block 1023 penetrates the movable connecting plate 1011 and is slidably engaged, and the vertical section of the locking block 1023 is slidably engaged with the arc groove 13. First, press the movable block 1021 to move it away from the mounting frame 1. The limiting spring 1022 gradually contracts, and the locking block 1023 moves from the limiting groove 12 to the arc groove 13. At this time, rotate the handle 1012 to make the locking block 1023 connected to the handle 1012 rotate until the locking block 1023 moves to the position of the middle arc groove 13. Then release the movable block 1021, and the limiting spring 1022 gradually extends. Both the movable block 1021 and the locking block 1023 move towards the mounting frame 1 until the locking block 1023 slides into the arc groove 13. At this time, the locking block 92 is separated from the limiting through hole 95, and the glass frame 2 can be rotated. Similarly, after separating the locking block 1023 from the middle arc groove 13, continue to rotate the handle 1012 until the locking block 1023 moves to the position of another arc groove 13, and connect the locking block 1023 to the arc groove 13. At this time, the positioning rod 6 is separated from the positioning through hole 7, and the glass frame 2 can be pushed, pulled and slid. The setting of the limiting component 102 improves the stability of the rotating rod 823 when it is stationary.

[0040] The positioning assembly 81 also includes rollers 814, which are rotatably mounted on the vertical rod 812 and rollably connected to the lifting block 824. The rollers 814 reduce the friction between the vertical rod 812 and the lifting block 824.

[0041] A limiting rod 94 is fixed inside the glass frame 2, and the limiting rod 94 passes through the locking block 92 and slides in engagement with it. The setting of the limiting rod 94 improves the stability of the locking block 92 during movement.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
