Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy sliding door technology, specifically an aluminum alloy sliding door with a buffer structure. Background Technology

[0002] Aluminum alloys are lightweight, high-strength, corrosion-resistant, easy to process, and highly recyclable, making them an ideal alternative to traditional wood and steel. In modern homes and commercial spaces, aluminum alloy sliding doors are widely used due to their lightweight, corrosion-resistant, and aesthetically pleasing properties.

[0003] Traditional aluminum alloy sliding doors, lacking an effective buffer structure, are prone to generating significant impact forces between the door leaf and frame when closed. This can easily cause wear and tear on the sliding door components, reduce their service life, and potentially pose safety hazards. Therefore, those skilled in the art have provided an aluminum alloy sliding door with a buffer structure to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum alloy sliding door with a buffer structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sliding aluminum alloy door with a buffer structure includes a door frame body, a fixed door leaf connected inside the door frame body, and sliding tracks provided on the inner bottom wall and the inner top wall of the door frame body. A set of pulleys is slidably connected inside each of the two sliding tracks, and a movable door leaf is connected to the side of the two sets of pulleys that are close to each other. Limiting mechanisms are provided on the inner bottom wall and the inner top wall of the door frame body. Two first grooves are provided on the inner side wall of the door frame body, and a first magnet is installed on the inner wall of each of the two first grooves. Second magnets are connected to the left and right sides of the movable door leaf. Two second grooves are provided on the inner side wall of the door frame body, and hydraulic cylinders are installed on the inner walls of each of the two second grooves. Piston rods are installed at the output ends of each of the two hydraulic cylinders, and fixed discs are connected to the ends of the two piston rods that are close to each other. Buffer springs are connected to the inner walls of each of the two first grooves. A door handle is connected to the front of the movable door leaf.

[0007] As a further improvement of this utility model: both of the limiting mechanisms include limiting grooves, and each limiting groove has a set of limiting blocks slidably connected inside. The sides of the two sets of limiting blocks that are close to each other are respectively connected to the bottom surface and the top surface of the movable door leaf.

[0008] As a further improvement of this utility model: the door frame body is made of high-strength aluminum alloy profile, and the outer surface of the door frame body is provided with an oxide film.

[0009] As a further improvement of this utility model: each piston rod is made of high-strength alloy material, the hydraulic cylinder is made of stainless steel material, and each buffer spring is made of high-quality spring steel material.

[0010] As a further improvement of this utility model: the outer surfaces of both the movable door leaf and the fixed door leaf are frosted, and both the first magnet and the second magnet are made of neodymium iron boron permanent magnet material.

[0011] As a further improvement of this utility model: a sealing strip is connected to the outer surface of the door frame body, and a buffer pad is connected to the side of the two fixing plates that are close to each other.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This aluminum alloy sliding door with a buffer structure uses a buffer spring in conjunction with a hydraulic cylinder. When the sliding door reaches the end of its travel, the buffer spring first provides initial buffering, absorbing some of the impact force. Then, the piston rod of the hydraulic cylinder drives the fixed plate to further slow down the closing speed of the door. This effectively reduces the impact force generated by the collision between the sliding door and the door frame, thus not only avoiding wear and damage caused by the collision, but also extending the service life of the sliding door. At the same time, it also avoids noise generated by violent collisions, creating a quiet environment for use. Attached Figure Description

[0022] Please see Figures 1-5In this embodiment of the present invention, an aluminum alloy sliding door with a buffer structure includes a door frame body 1, a fixed door leaf 2 connected inside the door frame body 1, a slide rail 3 provided on the inner bottom wall and the inner top wall of the door frame body 1, a set of pulleys 4 slidably connected inside the two slide rails 3, and a movable door leaf 5 connected to the side of the two sets of pulleys 4 that are close to each other, a limit mechanism 6 provided on the inner bottom wall and the inner top wall of the door frame body 1, two first grooves 7 provided on the inner side wall of the door frame body 1, a first magnet 8 installed on the inner wall of the two first grooves 7, and the left and right sides of the movable door leaf 5 are connected to... A second magnet 9 is connected to the inner wall of the door frame body 1. Two second grooves 10 are opened on the inner wall of the two second grooves 10. A hydraulic cylinder 11 is installed on the inner wall of each of the two second grooves 10. A piston rod 12 is installed on the output end of each of the two hydraulic cylinders 11. A fixed plate 13 is connected to the end of each piston rod 12 that is close to each other. A buffer spring 14 is connected to the inner wall of each of the two first grooves 7. A door handle 15 is connected to the front of the movable door leaf 5. Through the mutual attraction between the first magnet 8 and the second magnet 9, the movable door leaf 5 can be tightly attracted to the door frame body 1 when closed, which can enhance the sealing between the movable door leaf 5 and the door frame body 1.

[0023] Both limiting mechanisms 6 include limiting grooves 601, and each limiting groove 601 has a set of limiting blocks 602 slidably connected inside. The two sets of limiting blocks 602 are connected to the bottom surface and the top surface of the movable door leaf 5 respectively on their side closest to each other. The door frame body 1 is made of high-strength aluminum alloy profile, and the outer surface of the door frame body 1 is covered with an oxide film. Each piston rod 12 is made of high-strength alloy material, the hydraulic cylinder 11 is made of stainless steel material, and each buffer spring 14 is made of high-quality spring steel material. By using the cooperation of the limiting grooves 601 and the limiting blocks 602, combined with the upper slide rail 3 and the pulley 4, the movable door leaf 5 can be kept stable during the sliding process without shaking or deflection. The oxide film on the outer surface of the door frame body 1 can improve its wear resistance, corrosion resistance and aesthetics. The stainless steel material of the hydraulic cylinder 11 and the high-strength alloy material of the piston rod 12 can not only ensure its sealing and corrosion resistance, but also ensure that it will not deform or wear during long-term use.

[0024] The outer surfaces of both the movable door leaf 5 and the fixed door leaf 2 are frosted. The first magnet 8 and the second magnet 9 are both made of neodymium iron boron permanent magnet material. The outer surface of the door frame body 1 is connected with a sealing strip 16. The two fixed plates 13 are connected with buffer pads 17 on their adjacent sides. By using the neodymium iron boron permanent magnet material of the first magnet 8 and the second magnet 9, the movable door leaf 5 and the door frame body 1 can be tightly closed together. The sealing strip 16 can further enhance the sealing between the door frame body 1 and the wall.

[0025] The working principle of this utility model is as follows: When the movable door leaf 5 needs to be opened, the user holds the door handle 15 and applies external force, which in turn drives the movable door leaf 5 to overcome the attraction between the first magnet 8 and the second magnet 9, so that the movable door leaf 5 slides along the slide 3 under the action of the pulley 4 in the slide 3. At the same time, the limiting block 602 slides synchronously in the limiting groove 601, limiting and guiding the sliding of the movable door leaf 5 to ensure its smooth sliding. When the movable door leaf 5 slides to the side close to the door frame body 1, the buffer spring 14 on the side close to the door frame body 1 first contacts the movable door leaf 5 and is compressed, thus initially buffering and decelerating the movable door leaf 5. As the movable door leaf 5 continues to move, the piston rod 12 of the hydraulic cylinder 11 extends under hydraulic action, driving the fixed plate 13 to contact the movable door leaf 5, further buffering the movable door leaf 5 until the movable door leaf 5 stops completely. At this time, the first magnet 8 and the second magnet 9 attract each other, so that the movable door leaf 5 is tightly closed. The above is the complete operation process of this device.
