Description

Technical Field

[0001] This utility model relates to the field of rotating shafts, specifically a rotating shaft with high stability. Background Technology

[0002] There are two main types of hinges used in existing electronic products. One type uses a cam and spring structure to enable rotation from one position to another. Most hinges are assembled from common parts to enable multi-angle rotation of the robotic arm. This type of hinge has many defects and shortcomings and needs further improvement.

[0003] Existing shafts typically employ simple cam and spring structures, or are assembled from multiple common parts. These structures lack sufficient stability features in their design and cannot effectively withstand the mechanical stresses of long-term use. For example, cam and spring structures are prone to losing elasticity due to spring fatigue during repeated rotation, leading to inaccurate positioning and loosening of the shaft. Existing shaft designs lack effective anti-loosening mechanisms. During prolonged use, frequent rotation and external mechanical stress can easily cause loosening at the shaft's connection points. For instance, threaded connections may gradually loosen under repeated torque, resulting in decreased shaft stability. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a rotating shaft with high stability, which can effectively solve the technical problem that existing rotating shafts have poor stability and are prone to loosening when rotating.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a highly stable rotating shaft, including an upper fixed seat, a lower fixed seat, and a handle. A rotating assembly is provided between the upper fixed seat and the lower fixed seat. The rotating assembly is sleeved between the upper fixed seat and the lower fixed seat. The rotating assembly includes a fixed ring formed by stacking upper and lower friction plates and a rotating component disposed on the fixed ring. The rotating component includes a fixed rotating shaft and a screw sleeved on the fixed rotating shaft. A washer is sleeved on the fixed rotating shaft. A groove is provided on the surface of the upper friction plate. One end of the washer is bent outward to form a locking block. One end of the locking block is inserted into the groove and engaged with the groove. Two spring pieces are sleeved on the end of the fixed rotating shaft near the washer. A fixing nut is sleeved on one end of the fixed rotating shaft. The fixing nut is threadedly connected to the fixed rotating shaft.

[0006] Furthermore, both the upper and lower friction plates are provided with bolts, the upper fixing seat is connected to the upper friction plate by bolts, and the lower fixing seat is connected to the lower friction plate by bolts.

[0007] Furthermore, one end of the screw extends outward to form a connecting part, and a top cover plate is fitted onto the connecting part. The top cover plate is rotatably connected to the upper fixed seat.

[0008] Furthermore, one end of both the upper and lower fixing seats has a connection port, and the surfaces of both the upper and lower fixing seats are provided with screw holes.

[0009] Furthermore, a fixing rod is provided at one end of the handle, and a spring is arranged around the surface of the fixing rod, with one end of the spring connected to the screw.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides a highly stable rotating shaft. By setting a shim and a spring on the fixed rotating shaft and using the cooperation of a locking block and a locking groove, the circumferential slippage of the shim is effectively prevented, ensuring the stability of the rotating shaft after long-term use. The setting of the spring further enhances the anti-torsion ability of the rotating shaft and prevents loosening. Attached Figure Description

Detailed Implementation

[0017] 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.

[0018] The following is combined Figures 1-4 A detailed description of a highly stable rotating shaft according to this utility model is provided:

[0019] A highly stable rotating shaft includes an upper fixed seat 1, a lower fixed seat 2, and a handle 3. A rotating assembly 20 is disposed between the upper fixed seat 1 and the lower fixed seat 2. The rotating assembly 20 is sleeved between the upper fixed seat 1 and the lower fixed seat 2. The rotating assembly 20 includes a fixed ring formed by stacking upper friction plates 15 and lower friction plates 16, and a rotating component 21 disposed on the fixed ring. The rotating component 21 includes a fixed rotating shaft 18 and a screw 19 sleeved on the fixed rotating shaft 18. A washer 9 is sleeved on the fixed rotating shaft 18. A groove 10 is provided on the surface of the upper friction plate 15. One end of the washer 9 is bent outward to form a locking block 11. One end of the locking block 11 is inserted into the groove and engaged with the groove 10. Two spring pieces 13 are sleeved on the end of the fixed rotating shaft 18 near the washer 9. A fixing nut 14 is sleeved on one end of the fixed rotating shaft 18. The fixing nut 14 is threadedly connected to the fixed rotating shaft 18.

[0020] Both the upper friction plate 15 and the lower friction plate 16 are provided with bolts 12. The upper fixed seat 1 is connected to the upper friction plate 15 by bolts 12, and the lower fixed seat 2 is connected to the lower friction plate 16 by bolts 12. The upper and lower friction plates 16 are connected to the upper and lower fixed seats 2 by bolts 12 respectively. This not only facilitates the quick disassembly and maintenance of the rotating shaft, but also ensures a tight fit between the friction plates and the fixed seats, preventing relative displacement, thereby enhancing the overall structural strength and stability of the rotating shaft.

[0021] One end of the screw 19 extends outward to form a connecting part 17. The connecting part 17 is fitted with a top cover plate 7. The top cover plate 7 is rotatably connected to the upper fixed seat 1.
