When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] like Figure 1-4As shown in the embodiment of this utility model, a rotating shaft with a limiting structure includes a movable component 10, a main shaft 20, and a housing 30. The housing 30 is provided with a cavity 31, the main shaft 20 is disposed within the cavity 31, the movable component 10 is sleeved on the main shaft 20, and the movable component 10 moves along the main shaft 20 within the cavity 31. A limiting groove 32 is provided on one side of the housing 30, and a limiting block 11 is provided on one side of the movable component 10 corresponding to the limiting groove 32. The limiting block 11 is movably limited within the limiting groove 32. In this embodiment, the cavity 31 provided within the housing 30 facilitates the installation of the main shaft 20 and the movable component 10, effectively improving the compactness and integration of the structure; it provides precise movement space for the main shaft 20 and the movable component 10, thereby improving the accuracy of the movable component 10's movement within the cavity 31.

[0028] like Figure 1 As shown, the movable component 10 includes a movable platform 12 and a connecting end 13; the movable platform 12 includes a first movable surface 121 and a second movable surface 122, and the limiting block 11 is disposed at one end of the first movable surface 121. In this embodiment, the cooperation of the first movable surface 121 and the second movable surface 122 enhances the stability of the movable component 10 moving along the main shaft 20 within the cavity 31, and the limiting block 11, disposed at one end of the first movable surface 121, effectively improves the accuracy of the movable component 10 moving within the cavity 31. Furthermore, the cooperation between the limiting block 11 and the limiting groove 32 enhances the limiting performance of the movable component 10, improves its accuracy, and makes it highly practical.

[0029] like Figure 2 As shown, a through groove 123 is provided between the first movable surface 121 and the second movable surface 122, and one end of the main shaft 20 can pass through the through groove 123. In this embodiment, the through groove 123 allows the main shaft 20 to pass through the through groove 123 and connect with the movable part 10, enhancing the stability of the connection between the main shaft 20 and the movable part 10. This allows the main shaft 20 to install the movable part 10 in the wall, enabling the movable part 10 to move within the cavity 31, improving the movement accuracy of the movable part 10, effectively reducing the deformation or loosening of the movable part 10 caused by external forces and prolonged use, and extending the service life of the movable part 10 within the cavity 31. This design is highly practical.

[0030] The main shaft 20 includes a connecting rod 21. A wave spring 22 is disposed above the connecting rod 21 near the first movable surface 121, and a mounting nut 23 is disposed above the connecting rod 21 near the wave spring 22. The connecting rod 21, together with the wave spring 22 and the mounting nut 23, forms a first damping zone 24. In this embodiment, the connecting rod 21 is used to connect and install the movable component 10 into the cavity 31, improving the structural stability and integration. The main shaft 20 is also provided with the wave spring 22 and the mounting nut 23 to form the first damping zone 24. Through the first damping zone 24, the vibration and impact generated when the movable component 10 moves on the connecting rod 21 can be absorbed and dispersed to a certain extent, thereby effectively reducing the wear between the movable component 10 and the main shaft 20 and extending the service life of the movable component 10. The wave spring 22, in conjunction with the mounting nut 23, effectively improves the compactness of the movable component 10's movement on the main shaft 20 and enhances the movement accuracy of the movable component 10.

[0031] The wave spring 22 includes a first spring 221, a second spring 222, and a third spring 223. One end of the first spring 221 and the second spring 222 is provided with a first flat end 224 facing the movable member 10, and one end of the third spring 223 is provided with a first groove 225 facing the movable member 10. In this embodiment, the first flat end 224 and the first groove 225 facilitate the connection and engagement between the main shaft 20 and the housing 30. The first flat end 224 is used to position the movable member 10 when it is installed in the cavity 31, improving installation strength and preventing improper installation. The first groove 225, in conjunction with the movable member 10, improves the movement accuracy of the movable member 10 within the cavity 31.

[0032] An elastic washer 25 is disposed below the connecting rod 21 near the second movable surface 122, and a protective washer 26 is disposed below the elastic washer 25 at one end of the connecting rod 21. The connecting rod 21 forms a second damping zone 27 through the elastic washer 25 and the protective washer 26 disposed above the second movable surface 122. In this embodiment, the second damping zone 27 is used to limit the second movable surface 122, thereby improving the accuracy of the moving part 10 in its movement on the main shaft 20. The elastic washer 25 provides a damping effect when the moving part 10 moves on the connecting rod 21, thereby effectively improving the movement accuracy of the moving part 10.

[0033] like Figure 3As shown in the above embodiments, by respectively setting the first damping area 24 and the second damping area 27 at the upper and lower ends of the movable part 10, the installation strength of the movable part 10 on the main shaft 20 can be enhanced, and the damping generated when the movable part 10 moves on the connecting rod 21 can be improved, so as to improve the movement accuracy of the movable part 10 and effectively protect the movable part 10 to avoid the movable part 10 abutting against the outer shell 30 when it moves in the cavity 31, thereby causing wear. This structure is compact, highly integrated, and practical.

[0034] The elastic pad 25 includes a first pad 251 and a second pad 252. One end of the first pad 251 is provided with a second groove 253 facing the movable member 10, and one end of the second pad 252 is provided with a second flat end 254 facing the movable member 10. In this embodiment, one end of the first groove 251 and the second groove 253 contacts the connecting rod 21 to improve the installation accuracy between the spindle 20 and the movable member 10. Both the first groove 225 and the second groove 253 are annular, so that when the movable member 10 moves along the spindle 20, it drives the first groove 225 and the second groove 253 to move on the positioning pin 12, which greatly enhances the stability of the movable member 10 on the spindle 20 and thus improves the movement accuracy. The double-layer elastic pad 25 can greatly improve the elasticity of the movable member 10 on the spindle 20, thereby enhancing the user's experience and improving practicality.

[0035] One end of the connecting rod 21 is rounded, and the other end is provided with a limiting plate 211, one side of which is flat. In this embodiment, the rounded corner of one end of the connecting rod 21 facilitates the assembly of the moving part 10 and the outer shell 30, effectively reducing wear on the moving part 10 and the outer shell 30; and the limiting plate 211 at the other end allows the elastic pad 25, the moving part 10, and the wave spring 22 to be stacked, resulting in a compact structure and strong practicality.

[0036] Limiting strips 311 are provided on the inner wall of the cavity 31. Multiple sets of limiting strips 311 are provided, and a flat groove 312 is provided between adjacent sets of limiting strips 311. The flat groove 312 is used to install the first planar end 224 and the second planar end 254, which are then limited by the limiting block 11. In this embodiment, the flat groove 312 facilitates the installation of the first planar end 224 and the second planar end 254 between the elastic pad 25 and the wave spring 22, effectively improving the installation accuracy of the main shaft 20 driving the movable part 10 within the cavity 31 and enhancing installation stability.

[0037] The outer casing 30 includes a mounting element 33 and a mounting end cap 34. The mounting element 33 is used to mount the outer casing 30, and the mounting end cap 34 is disposed on the top of the cavity 31. In this embodiment, the mounting element 33 is used to mount other objects onto the outer casing 30, and the mounting end cap 34 is provided on the outer casing 30. The mounting end cap 34 can be fastened to the top of the cavity 31 to protect the main shaft 20 and the moving parts 10 inside the cavity 31, preventing the entry of impurities from affecting the movement of the moving parts 10. This design is highly practical.

[0038] In an embodiment of this utility model, a rotating shaft with a limiting structure includes a movable component 10, a main shaft 20, and a housing 30. The housing 30 has a cavity 31, the main shaft 20 is disposed within the cavity 31, the movable component 10 is sleeved on the main shaft 20, and the movable component 10 moves along the main shaft 20 within the cavity 31. A limiting groove 32 is provided on one side of the housing 30, and a limiting block 11 is provided on one side of the movable component 10 corresponding to the limiting groove 32. The limiting block 11 is movably limited within the limiting groove 32. The main shaft 20 is used to install the movable component 10 within the cavity 31, allowing the movable component 10 to move within the cavity 31, improving the flexibility and smoothness of the movable component 10, and resulting in a compact structure. It features a high degree of integration; the main spindle 20 is equipped with a wave spring 22 and an elastic pad 25, which are respectively set at both ends of the movable part 10 to form a first damping zone 24 and a second damping zone 27 at both ends of the movable part 10. When the movable part 10 moves on the main spindle 20, the first damping zone 24 and the second damping zone 27 cooperate to limit the movable part 10 on the main spindle 20, thereby achieving internal limiting and improving the accuracy of the movement. The limiting groove 32 on the outer shell 30 and the limiting block 11 on the movable part 10 cooperate to limit the movement, thereby achieving external limiting. Through the inner and outer limiting structure, the accuracy of the movable part 10 in limiting the movement within the cavity 31 can be greatly improved. It is highly practical and has good application prospects.
