Description

Technical Field

[0001] This utility model relates to the field of sliding rail technology, specifically a silent sliding door sliding rail structure. Background Technology

[0002] Sliding doors are a common type of door, offering significant advantages in space utilization and convenience due to their unique sliding opening mechanism. Sliding doors achieve planar sliding of the door panels through a track system, eliminating the need for swaying and thus greatly saving interior space. They come in a variety of designs, allowing users to choose materials, styles, and functions such as glass, wood, or metal to suit different needs, easily matching various interior design styles. Sliding doors are widely used in homes, commercial spaces, and public places, such as kitchens, bedrooms, balconies, and shop entrances, providing a convenient and stylish opening method.

[0003] The rollers at the bottom of sliding doors are typically mounted flexibly via a movable axle. This axle design allows the rollers to move freely horizontally, ensuring smooth opening and closing of the door. However, these movable axles often lack effective lubrication, leading to wear and tear over time. As wear increases, the noise generated when the sliding door slides also becomes louder, affecting the user experience and overall noise reduction. Utility Model Content

[0004] The purpose of this invention is to provide a silent sliding door track structure to solve the problem of easy wear of the moving shaft in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silent sliding door track structure, including a sliding track, on which a pulley body is rotatably mounted, and a pulley frame is mounted on the pulley body. The upper end of the pulley frame has a mounting through hole, and a movable shaft is rotatably mounted inside the pulley frame. A lubrication mechanism is provided at the connection between the movable shaft and the pulley frame. The lubrication mechanism includes sealing covers fixedly mounted on both sides of the pulley frame and protrusions fixedly mounted on the edges of both ends of the movable shaft. A lubricating oil channel is fixedly mounted on the upper end of the sealing cover. A spring seat is fixedly installed inside, and a compression spring is provided below the spring seat. A sealing steel ball is movably installed at the lower end of the lubricating oil passage. An oil storage mechanism is connected to the pulley frame. The oil storage mechanism includes lubricating oil tanks fixedly installed on both sides of the pulley frame. A docking pipe is provided at the bottom of the lubricating oil tank, and the lower end of the docking pipe is connected to the upper end of the lubricating oil passage. A docking base is fixedly installed on the lubricating oil tank. A branch pipe is connected to the lubricating oil tank, and a refueling pipe is connected to the branch pipe. A sealing end cap is installed at the end of the refueling pipe. After opening the sealing end cap, oil can be added to the lubricating oil tank.

[0006] Preferably, the spring seat has an oil passage hole, the bottom of the lubricating oil passage has an oil injection hole, and a sealing steel ball is plugged in the oil injection hole.

[0007] Preferably, the sealing cover has an installation port, and the lubricating oil passage is installed on the sealing cover through the installation port.

[0008] Preferably, one end of the compression spring is fixed to the spring seat, and the other end of the compression spring is fixed to the sealing steel ball. The protrusion and the sealing steel ball are located in the same vertical plane. The compression spring provides elastic force to the sealing steel ball, causing the sealing steel ball to tend to move downward.

[0009] Preferably, the docking base has docking through holes at its four corners, and bolts are installed in the docking through holes. The docking base is fixed to the pulley frame by bolts.

[0010] Preferably, the lubricating oil tank is provided with a connection port, and the branch pipe is connected to the lubricating oil tank through the connection port.

[0011] Preferably, the lubricating oil tank is installed on both sides of the pulley frame via a docking base, one end of the branch pipe is connected to the refueling pipe, and the other end of the branch pipe is connected to the lubricating oil tank.

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

[0013] 1. In this application, after the lubricating oil tank is fixed on both sides of the pulley frame, the refueling pipe can be installed on the side wall of the aluminum alloy door frame. The user only needs to open the sealed end cap to add lubricating oil to the lubricating oil tank, and the lubricating oil in the lubricating oil tank can be transported to the lubricating oil channel through the docking pipe.

[0014] 2. In this application, during the rotation of the movable shaft, the protruding block driven by it rotates accordingly. During the rotation, the protruding block periodically applies pressure to the sealing steel ball, causing the oil injection hole at the bottom of the lubrication channel to open. Once the oil injection hole at the bottom of the lubrication channel is opened, the lubricating oil in the lubrication channel can enter the sealing cover body. Subsequently, this lubricating oil will penetrate to the connection part between the movable shaft and the pulley frame body, thereby achieving the lubrication effect on the movable shaft and reducing the generation of noise.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a silent sliding door track structure, including a sliding track 1, a pulley body 2 rolled on the sliding track 1, a pulley frame 3 mounted on the pulley body 2, an installation through hole 4 at the upper end of the pulley frame 3, a movable shaft 5 rotatably mounted inside the pulley frame 3, a lubrication mechanism 7 provided at the connection between the movable shaft 5 and the pulley frame 3, and an oil storage mechanism 6 connected to the pulley frame 3. Through the cooperation of the oil storage mechanism 6 and the lubrication mechanism 7, the movable shaft 5 can be lubricated, thereby reducing the generation of noise.

[0022] like Figure 2 and Figure 3 As shown, the oil storage mechanism 6 includes a lubricating oil tank 605 fixedly installed on both sides of the pulley frame 3. The bottom of the lubricating oil tank 605 is provided with a docking pipe 607, and the lower end of the docking pipe 607 is connected to the upper end of the lubricating oil passage 701. A docking base 603 is fixedly installed on the lubricating oil tank 605. A branch pipe 606 is connected to the lubricating oil tank 605. A refueling pipe 602 is connected to the branch pipe 606. A sealing end cap 601 is installed at the end of the refueling pipe 602. A docking through hole 604 is opened at the four corners of the docking base 603, and a bolt is provided in the docking through hole 604. The docking base 603 is fixed to the pulley frame 3 by bolts. A connection port is opened on the lubricating oil tank 605, and the branch pipe 606 is connected to the lubricating oil tank 605 through the docking port.

[0023] Specifically, the lubricating oil tank 605 is firmly fixed to both sides of the pulley frame 3. In this way, the user can easily install the oil filling pipe 602 on the side wall of the aluminum alloy door frame. When the user needs to add lubricating oil, he / she can simply open the sealing end cap 601 to easily inject the lubricating oil into the lubricating oil tank 605. In addition, the lubricating oil in the lubricating oil tank 605 can be smoothly transported to the lubricating oil channel 701 through the connecting pipe 607 to ensure that the lubrication needs of the entire system are met. This design not only facilitates the user's operation, but also ensures the smooth flow of lubricating oil, thereby improving the operating efficiency and service life of the equipment.

[0024] like Figure 2 and Figure 4 As shown, the lubrication mechanism 7 includes a sealing cover 704 fixedly installed on both sides of the pulley frame 3 and a protrusion 705 fixedly installed on the edges of both ends of the movable shaft 5. A lubrication oil passage 701 is fixedly installed on the upper end of the sealing cover 704. A spring seat 702 is fixedly installed inside the lubrication oil passage 701. A compression spring 703 is provided below the spring seat 702. A sealing steel ball 706 is movably installed at the lower end of the lubrication oil passage 701. An oil passage 707 is provided on the spring seat 702. An oil injection hole is provided at the bottom of the lubrication oil passage 701, and the sealing steel ball 706 is plugged in the oil injection hole. An installation port is provided on the sealing cover 704, and the lubrication oil passage 701 is installed on the sealing cover 704 through the installation port.

[0025] Specifically, the compression spring 703 provides elasticity to the sealing steel ball 706, causing the sealing steel ball 706 to block the oil injection hole. After the movable shaft 5 rotates, it will drive the protrusion block 705 to rotate. During the rotation of the protrusion block 705, it will press the sealing steel ball 706 back and forth, causing the oil injection hole at the bottom of the lubrication channel 701 to open. After the oil injection hole at the bottom of the lubrication channel 701 is opened, the lubricating oil in the lubrication channel 701 will enter the sealing cover 704. The lubricating oil entering the sealing cover 704 will then seep into the connection between the movable shaft 5 and the pulley frame 3, thereby lubricating the movable shaft 5 and reducing the generation of noise.

[0026] Working principle: During use, the docking base 603 is fixed to the pulley frame 3 with bolts, thereby fixing the lubricating oil tank 605 to both sides of the pulley frame 3. After the lubricating oil tank 605 is fixed to both sides of the pulley frame 3, the filling pipe 602 can be installed on the side wall of the aluminum alloy door frame. The user only needs to open the sealing end cover 601 to add lubricating oil to the lubricating oil tank 605, and the lubricating oil in the lubricating oil tank 605 can be transported to the lubricating oil channel 701 through the docking pipe 607. The pulley body 2 moves along the sliding track 1 When it rolls, it will drive the movable shaft 5 to rotate. After the movable shaft 5 rotates, it will drive the protrusion 705 to rotate. During the rotation of the protrusion 705, it will press the sealing steel ball 706 back and forth, so that the oil injection hole at the bottom of the lubricating oil channel 701 will open. After the oil injection hole at the bottom of the lubricating oil channel 701 is opened, the lubricating oil in the lubricating oil channel 701 will enter the sealing cover 704. The lubricating oil that enters the sealing cover 704 will seep into the connection between the movable shaft 5 and the pulley frame 3, thereby lubricating the movable shaft 5 and reducing the generation of noise.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
