[0001] This utility model relates to the field of sliding door technology, and more specifically, to a sliding door with a self-lubricating structure. Background Technology

[0002] Sliding doors are a common type of door. When a user pulls a sliding door, the door moves within the door frame via wheels. However, during prolonged rotation, the connection between the wheels and the door may become stuck or friction may increase. Additionally, the wheels may also become stuck between themselves and the door frame. All of these issues can cause unusual noises when the user pushes or pulls the door, and may also cause the door to become stuck. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a sliding door with a self-lubricating structure, which has the advantage of self-lubrication.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-lubricating sliding door, including a door frame, a sliding door body disposed within the inner cavity of the door frame, a connecting ring fixedly connected to the bottom end of the sliding door body, a traveling wheel movably sleeved within the inner cavity of the connecting ring, an anti-slip transmission belt movably sleeved on the surface of the traveling wheel, a storage box fixedly connected to the inner cavity of the sliding door body, a threaded blocking tube fixedly connected to the bottom end of the storage box, a threaded rod threadedly connected to the front side of the threaded blocking tube, a blocking block fixedly connected to the rear side of the threaded rod, a discharge pipe fixedly connected to the bottom end of the threaded blocking tube, an application bin fixedly connected to the bottom end of the discharge pipe, and an application wheel movably connected to the bottom end of the application bin.

[0005] As a preferred embodiment of this utility model, the bottom end of the mounting door frame is provided with a threaded groove, the inner cavity of the threaded groove is threadedly connected to a mounting bolt, and a blocking plate is movably fitted on the surface of the mounting bolt.

[0006] As a preferred embodiment of this utility model, an adding tube is fixedly connected to the top of the storage box, and the adding tube communicates with the inner cavity of the storage box.

[0007] As a preferred embodiment of this utility model, a threaded ring is fixedly connected to the front side of the threaded blocking tube, and the threaded rod is threadedly connected to the inner cavity of the threaded ring.

[0008] In a preferred embodiment of this invention, the walking wheel is connected to the application wheel via an anti-slip transmission belt, and the application wheel is in contact with the walking wheel.

[0009] As a preferred embodiment of this utility model, a rotating rod is fixedly connected to the front side of the threaded rod, and the blocking block is in contact with the inner wall of the threaded blocking tube.

[0010] As a preferred embodiment of this utility model, the side of the coating wheel closest to the coating chamber is located inside the coating chamber, the center of the coating wheel is located below the outer side of the coating chamber, and the discharge pipe is in communication with the inner cavity of the coating chamber.

[0011] As a preferred embodiment of this utility model, there are four threaded grooves, which are respectively opened on the upper and lower sides of the mounting door frame, and the blocking plate is in contact with the front side of the mounting door frame.

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

[0013] 1. This utility model achieves self-lubrication of the connection between the traveling wheel and the door frame by rotating the traveling wheel within the inner cavity of the mounting frame, and by driving the application wheel to apply the lubricating oil from the application chamber to the surface of the traveling wheel. This lubricates the connection between the traveling wheel and the mounting frame, and the lubricating oil also enters the connection between the traveling wheel and the connecting ring, thus preventing jamming or abnormal noise.

[0014] 2. This utility model rotates the mounting bolt by turning it, and then moves the mounting bolt to the outside of the mounting door frame through the threaded groove. After the mounting bolt leaves the inner cavity of the threaded groove, the blocking plate is released, allowing the blocking plate to be disassembled. Then, the sliding door body can be placed in the inner cavity of the mounting door frame or taken out of the inner cavity of the mounting door frame. This improves the convenience of installing or removing the sliding door body and avoids the situation where the sliding door body is stuck during disassembly. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a sliding door with a self-lubricating structure, including a door frame 1, a sliding door body 2 in the inner cavity of the door frame 1, a connecting ring 3 fixedly connected to the bottom end of the sliding door body 2, a traveling wheel 4 movably sleeved in the inner cavity of the connecting ring 3, an anti-slip transmission belt 5 movably sleeved on the surface of the traveling wheel 4, a storage box 6 fixedly connected to the inner cavity of the sliding door body 2, a threaded blocking tube 8 fixedly connected to the bottom end of the storage box 6, a threaded rod 9 threadedly connected to the front side of the threaded blocking tube 8, a blocking block 10 fixedly connected to the rear side of the threaded rod 9, a discharge pipe 12 fixedly connected to the bottom end of the threaded blocking tube 8, an application chamber 13 fixedly connected to the bottom end of the discharge pipe 12, and an application wheel 14 movably connected to the bottom end of the application chamber 13.

[0023] When lubrication is needed, rotating the rotating rod 11 drives the threaded rod 9 to rotate. Then, through the meshing between the threaded rod 9 and the threaded blocking tube 8, the blocking block 10 is moved, causing the blocking block 10 to leave the connection between the threaded blocking tube 8 and the storage box 6. At this time, the lubricating oil in the inner cavity of the storage box 6 enters the inner cavity of the coating chamber 13 along the threaded blocking tube 8 and the discharge pipe 12. When the traveling wheel 4 rotates and moves in the inner cavity of the mounting frame 1, the anti-slip transmission belt 5 drives the coating wheel 14 to rotate, thereby driving the coating wheel 14 to apply the lubricating oil in the inner cavity of the coating chamber 13 to the surface of the traveling wheel 4, thus lubricating the traveling wheel 4 and the mounting frame 1. The lubricating oil also enters the connection ring 3 and the traveling wheel 4 along the traveling wheel 4, thus lubricating them. This achieves self-lubrication of the connection between the traveling wheel 4 and the connecting ring 3, as well as between the traveling wheel 4 and the mounting frame 1, thereby preventing jamming or abnormal noise.

[0024] Among them, the bottom end of the mounting door frame 1 is provided with a threaded groove 15, the inner cavity of the threaded groove 15 is threadedly connected with a mounting bolt 16, and a baffle plate 17 is movably fitted on the surface of the mounting bolt 16.

[0025] By rotating the mounting bolt 16 and then moving it outward through the threaded groove 15, the mounting bolt 16 is released from the inner cavity of the threaded groove 15, allowing the blocking plate 17 to be disassembled. Then, the sliding door 2 can be placed in the inner cavity of the mounting door frame 1 or removed from the inner cavity of the mounting door frame 1. This improves the convenience of installing or removing the sliding door 2 and avoids the situation where the sliding door 2 gets stuck during disassembly.

[0026] The top of the storage box 6 is fixedly connected to an addition tube 7, which is in communication with the inner cavity of the storage box 6.

[0027] The addition tube 7 at the top of the storage tank 6 is connected to the inner cavity of the storage tank 6, allowing the user to add lubricating oil to the inner cavity of the storage tank 6 to replenish the lubricating oil in the inner cavity of the storage tank 6.

[0028] Among them, a threaded ring is fixedly connected to the front side of the threaded blocking tube 8, and the threaded rod 9 is threadedly connected to the inner cavity of the threaded ring;

[0029] The threaded rod 9 is threaded into the threaded ring, so that the threaded rod 9 can move when it rotates. In turn, the threaded rod 9 can drive the blocking block 10 to move. The movement of the blocking block 10 can block the connection between the storage tank 6 and the threaded blocking pipe 8, or remove the blocking block 10 to allow the storage tank 6 and the threaded blocking pipe 8 to pass through, thereby controlling the flow of lubricating oil.

[0030] Among them, the walking wheel 4 is connected to the coating wheel 14 via the anti-slip transmission belt 5, and the coating wheel 14 is in contact with the walking wheel 4;

[0031] The traveling wheel 4 is connected to the application wheel 14 via the anti-slip transmission belt 5, so that when the traveling wheel 4 rotates, it can drive the anti-slip transmission belt 5 to rotate, and then the rotation of the anti-slip transmission belt 5 drives the application wheel 14 to rotate. Through the contact between the application wheel 14 and the traveling wheel 4, the application wheel 14 can evenly apply lubricating oil to the surface of the traveling wheel 4.

[0032] Among them, the front side of the threaded rod 9 is fixedly connected to the rotating rod 11, and the blocking block 10 is in contact with the inner wall of the threaded blocking tube 8;

[0033] The rotating rod 11 on the front side of the threaded rod 9 allows the user to rotate the rotating rod 11 by hand, thereby driving the threaded rod 9 to rotate, which improves the convenience of the user when rotating the threaded rod 9.

[0034] The side of the coating wheel 14 closest to the coating chamber 13 is located inside the coating chamber 13, and the center of the coating wheel 14 is located below the outside of the coating chamber 13. The discharge pipe 12 is connected to the inner cavity of the coating chamber 13.

[0035] The applicator wheel 14 is located in the inner cavity of the applicator 13 near the applicator 13, so that the lubricating oil in the inner cavity of the applicator 13 can be applied to the surface of the travel wheel 4. The center of the applicator wheel 14 is located on the lower outer side of the applicator 13, so that the travel wheel 4 can be connected to the applicator wheel 14 through the anti-slip transmission belt 5.

[0036] There are four threaded grooves 15, which are respectively opened on the upper and lower sides of the mounting door frame 1, and the blocking plate 17 contacts the front side of the mounting door frame 1.

[0037] The four threaded grooves 15 enable the installation of four mounting bolts 16, thereby fixing the blocking plate 17 and facilitating its disassembly. This makes the installation and disassembly of the sliding door 2 easier.

[0038] The working principle and usage process of this utility model are as follows: unscrew the mounting bolt 16 from the inner cavity of the threaded groove 15, then remove the blocking plate 17, then place the sliding door body 2 in the inner cavity of the mounting door frame 1, and then pull the sliding door body 2 to slide in the inner cavity of the mounting door frame 1 to push and pull.

[0039] When lubrication is required at the connection between the connecting ring 3 and the traveling wheel 4, as well as at the contact surface between the traveling wheel 4 and the mounting frame 1, the rotating rod 11 is turned to rotate the threaded rod 9. The threaded rod 9 engages with the threaded blocking tube 8, thereby causing the blocking block 10 to move along the threaded rod 9. This allows the lubricating oil in the storage box 6 to be discharged from the threaded blocking tube 8 to the inner cavity of the discharge pipe 12, and then enters the inner cavity of the coating chamber 13 along the discharge pipe 12. When the traveling wheel 4 rotates and moves within the inner cavity of the mounting frame 1, it drives the coating wheel 14 to rotate. The lubricating oil in the inner cavity of the coating chamber 13 is then applied to the surface of the traveling wheel 4 to lubricate it. The lubricating oil also enters between the connecting ring 3 and the traveling wheel 4 along the traveling wheel 4 to lubricate the connection between the connecting ring 3 and the traveling wheel 4.
