Technical Field
[0001] This utility model belongs to the field of sliding door technology, and in particular relates to a design structure for a noise-proof sliding door for high-rise residential buildings. Background Technology
[0002] Sliding doors for residential buildings have become a popular choice in modern home decoration due to their space-saving, aesthetic, and practical features. They are often used to separate living rooms from balconies and to block out spaces between living rooms and kitchens, providing flexible space division. However, they have relatively weak sound insulation.
[0003] Currently, many residential sliding doors, while appearing to fit tightly when closed, have significant flaws in actual use. During windy weather, due to insufficient sealing in their structure and minute gaps between the track and the door, strong winds can easily enter through these gaps or edges, creating a pushing force that causes the door to be blown open. This unstable closure not only fails to effectively block external wind and noise, disrupting the quiet and comfortable indoor environment, but also generates sharp, piercing noise from the violent shaking of the door, severely interfering with residents' daily lives and rest. Over time, the frequent collisions and friction between the door and the track accelerate component wear, shortening the sliding door's lifespan and further increasing maintenance costs and safety hazards.
[0004] Chinese patent 202010597044.2 describes a sliding door with a buffer function, comprising an upper fixed frame, a lower fixed frame, and several sliding components located between the upper and lower fixed frames. The inner surface of the upper fixed frame has an opening buffer box and a closing buffer box corresponding to the sliding components. Adjacent sliding components are staggered. Each sliding component includes an H-shaped mounting groove located within the fixed frame. The mounting side of the H-shaped mounting groove connects to the door leaf, which is an integral curved structure. The connecting side of the H-shaped mounting groove connects to the upper fixed frame via a pulley, and a limiting component is also provided on the connecting side of the H-shaped mounting groove. This invention, employing the above-described structure, provides a sliding door with a buffer function, solving the problems of noise and rebound when the sliding door is pushed or pulled too forcefully. It also prevents hands from being pinched by the sliding door. Furthermore, the curved structure of the door leaf makes it aesthetically pleasing.
[0005] However, it cannot solve the problem that when sliding doors are closed, there are gaps, and strong winds can easily enter from the gaps or edges, creating a pushing force that causes the sliding doors to be blown open. Utility Model Content
[0006] The purpose of this utility model is to provide a noise-proof sliding door design for high-rise residential buildings, which addresses the problem that existing sliding doors do not close tightly, allowing wind to enter the gap and create a pushing force that causes the sliding door to be blown open. This causes repeated vibrations under wind force, generating noise and also causing wear and tear on the door leaf.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: a noise-proof sliding door design structure for high-rise residential buildings, comprising:
[0008] A door frame, with its side end mounted on a wall and its bottom mounted on the ground, wherein a plurality of parallel first guide rails are provided on the ground and a plurality of parallel second guide rails are provided on the top of the door frame;
[0009] The double-linkage sliding door has its top slidably connected to the second guide rail and its bottom slidably connected to the first guide rail;
[0010] A cam limiting component, which is connected to the inner wall of the top of the door frame, is used to limit the closing of the double-linkage sliding door.
[0011] As a further description of the above technical solution:
[0012] The double-linkage sliding door includes a first sliding door and a second sliding door. The bottom of the first sliding door is slidably connected to the first guide rail inside, and the top of the first sliding door is slidably connected to the second guide rail inside.
[0013] As a further description of the above technical solution:
[0014] The bottom of the second sliding door is slidably connected to the first guide rail on the outside, and the top of the second sliding door is slidably connected to the second guide rail on the outside.
[0015] As a further description of the above technical solution:
[0016] The second sliding door is provided with a limiting plate, which extends to the inside of the first sliding door.
[0017] As a further description of the above technical solution:
[0018] The cam limiting component includes a fixed plate, a connecting shaft, and a cam. The cam is connected to the connecting shaft via a torsion spring, and the connecting shaft is connected to the fixed plate. The top of both the first sliding door and the second sliding door is provided with a receiving groove, and the cam and the receiving groove correspond to each other.
[0019] As a further description of the above technical solution:
[0020] The bottom of the cam is V-shaped.
[0021] As a further description of the above technical solution:
[0022] Both the first sliding door and the second sliding door include a frame and double-glazed glass, with the double-glazed glass installed within the frame.
[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0024] 1. In this utility model, a cam limiting component is installed on the inner wall of the top of the door frame. The cam limiting component is located at the side end of the first and second sliding doors. The top of the frames of the first and second sliding doors are provided with receiving grooves. When the first and second sliding doors are closed, the cam at the side end abuts against the outer wall of the receiving groove, thereby making the entire double-linkage sliding door form a sealed closed structure, which will not be affected by external wind force. To open the first and second sliding doors, simply push the first and second sliding doors by hand, so that the cam rotates along the connecting shaft and retracts into the receiving groove. When the first and second sliding doors are fully opened, the cam comes out of the receiving groove and resets under the action of the torsion spring, thus limiting the first or second sliding door and preventing it from vibrating due to wind force. This structure reduces maintenance costs and improves service life.
[0025] 2. In this utility model, a limiting plate is provided on the second sliding door. The limiting plate abuts against the first sliding door, which prevents the user from moving the sliding door in the wrong direction and also ensures the tightness of the double linkage sliding door when it is closed, thereby preventing it from being affected by external forces and reducing noise.

[0039] Please see Figure 1-4 This utility model provides a technical solution: a design structure for a noise-proof sliding door in a high-rise residential building, comprising:
[0040] The door frame 1 is mounted on the wall at its side and on the ground 2 at its bottom. Several parallel first guide rails 3 are provided on the ground 2, and several parallel second guide rails 4 are provided on the top of the door frame 1.
[0041] The double-linkage sliding door 5 is slidably connected at the top to the second guide rail 4 and slidably connected at the bottom to the first guide rail 3;
[0042] The cam 63 limiter 6 is connected to the top inner wall of the door frame 1 and is used to limit the double linkage sliding door 5 after it is closed.
[0043] The double-linkage sliding door 5 includes a first sliding door 51 and a second sliding door 52. The bottom of the first sliding door 51 is slidably connected to the first guide rail 3 inside, and the top of the first sliding door 51 is slidably connected to the second guide rail 4 inside.
[0044] The bottom of the second sliding door 52 is slidably connected to the first guide rail 3 on the outside, and the top of the second sliding door 52 is slidably connected to the second guide rail 4 on the outside.
[0045] A limiting plate 7 is provided on the second sliding door 52, and the limiting plate 7 extends to the inside of the first sliding door 51. This improves the sealing performance of the first and second sliding doors when they are tightly closed, preventing air from entering the gaps and exerting a pushing force on them.
[0046] The limiting member 6 of the cam 63 includes a fixed plate 61, a connecting shaft 62 and a cam 63. The cam 63 is connected to the connecting shaft 62 by a torsion spring. The connecting shaft 62 is connected to the fixed plate 61. The top of the first sliding door 51 and the second sliding door 52 are both provided with receiving grooves 8. The cam 63 and the receiving grooves 8 correspond to each other.
[0047] The bottom of the cam 63 is V-shaped. This facilitates the limiting of the side walls of the first and second sliding doors, and also allows the cam to rotate along the connecting shaft and retract into the receiving groove by manual pushing and pulling, and slide within the receiving groove, so that the first and second sliding doors can be pulled smoothly.
[0048] Both the first sliding door 51 and the second sliding door 52 include a frame and double-glazed glass, with the double-glazed glass installed within the frame. This improves sound insulation.
[0049] Working principle: A cam limiting component is installed on the inner wall of the top of the door frame. The cam limiting component is located at the side end of the first and second sliding doors. The top of the frames of the first and second sliding doors are provided with receiving grooves. When the first and second sliding doors are closed, the cam at the side end abuts against the outer wall of the receiving groove, thus forming a sealed closed structure for the entire double-linkage sliding door, which is not affected by external wind force. To open the first and second sliding doors, simply push the first and second sliding doors by hand, causing the cam to rotate along the connecting shaft and retract into the receiving groove. When the first and second sliding doors are fully opened, the cam comes out of the receiving groove and returns to its original position under the action of the torsion spring. This can limit the first or second sliding door and prevent it from vibrating due to wind force. This structure reduces maintenance costs and increases service life.
[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
