Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotating shaft technology, and in particular to a rotating shaft structure that provides audible prompts. Background Technology
[0002] When two relatively rotating objects (such as a rotating faucet or a rotating bracket) are connected, a pivot or rotating joint is required. To allow the user to feel and observe the angle of rotation during operation, a friction-generating mechanism is usually incorporated into the pivot or rotating joint to produce a clicking sound as the objects rotate relative to each other. For example, Chinese utility model patent CN219552887U discloses a knob structure that produces an adjustable sound effect. This structure includes a knob body, a spring, an adjusting spring block, a device cover, and a knob seat. The device cover has a mounting through hole, and an annular wave rib is provided along the outer periphery of the mounting through hole. The knob seat is located below the mounting through hole. A pivot is fixedly mounted on the knob body, which is positioned above the mounting through hole, allowing the pivot to pass through the mounting through hole and rotate to connect with the knob seat. An adjusting spring block is axially slidably mounted on the knob body, resting against the wave rib. As the knob body rotates, the adjusting spring block reciprocates up and down, vibrating relative to the wave rib to produce sound.
[0003] However, this structure is limited by installation space, and its springs and adjusting blocks need to be made relatively small. Small springs are more prone to fatigue failure, and their prompting sound effect tends to deteriorate after a period of use, so improvements are needed. Utility Model Content
[0004] To address the aforementioned problems, the purpose of this utility model is to provide a rotating shaft structure that emits a sound prompt. This structure is simple and reliable, easy to process and assemble, and can continuously emit a crisp shifting sound while maintaining a good shifting feel during rotation.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rotating shaft structure for emitting sound prompts includes an outer ring and an inner ring that can rotate relative to each other. The inner ring has a central hole. A rotating sound-emitting plate and an elastic element are provided between the outer ring and the inner ring. The outer ring has a cavity to accommodate the rotating sound-emitting plate and the elastic element. The inner wall of the outer ring has a ring of evenly arranged tooth grooves. The inner ring has a limiting plate for fitting the rotating sound-emitting plate. The rotating sound-emitting plate has meshing teeth. When the outer ring and the inner ring rotate relative to each other, the meshing teeth continuously engage with the tooth grooves to emit sound.
[0007] Furthermore, the elastic element includes an elastic ring with an opening and an elastic short rod, and the rotating sound-generating plate has a groove for accommodating the elastic short rod. The elastic ring presses the meshing teeth toward the groove through the elastic short rod.
[0008] Furthermore, an inner cover plate is provided at one end of the inner ring.
[0009] Furthermore, the inner cover plate and the inner ring are either integrally formed or separate components.
[0010] Furthermore, an outer cover plate is provided at one end of the outer ring.
[0011] Furthermore, the outer cover plate and the outer ring are either integrally formed or separately formed.
[0012] Furthermore, the rotating sound-generating plate is provided with an anti-rotation stop that cooperates with the limiting plate.
[0013] Furthermore, the limiting card platform includes at least two limiting edges.
[0014] Furthermore, the outer ring is circular or polygonal in shape.
[0015] Furthermore, the central hole of the inner ring is circular or polygonal.
[0016] This utility model has the following beneficial effects:
[0017] 1. This utility model features a rotating sound-generating plate and an elastic element positioned between a rotatable outer ring and an inner ring. The rotating sound-generating plate has meshing teeth, and the outer ring has a ring of evenly arranged tooth grooves. When the outer and inner rings rotate relative to each other, the meshing teeth continuously engage with the tooth grooves, producing a crisp clicking sound and maintaining a good tactile feel during rotation. Furthermore, the relative rotation angle is maintained after rotation, preventing significant wobbling. The rotating sound-generating plate and elastic element have a simple structure, high component strength, and are easy to process and assemble. After assembly, during rotational adjustment, the meshing teeth make active contact with the tooth grooves in the circumferential direction, reducing fatigue wear during use and facilitating long-term use.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1:
[0028] See Figure 1-4 As shown, a rotating shaft structure for emitting sound prompts includes an outer ring 1 and an inner ring 2 that can rotate relative to each other. The inner ring 2 has a central hole 21. A rotating sound-emitting plate 3 and an elastic element 4 are provided between the outer ring 1 and the inner ring 2. The outer ring 1 has a cavity 11 that accommodates the rotating sound-emitting plate 3 and the elastic element 4. The inner wall of the outer ring 1 has a ring of evenly arranged toothed grooves 12. The inner ring 2 has a limiting plate 22 for fitting the rotating sound-emitting plate 3. The rotating sound-emitting plate 3 has meshing teeth 31. The thickness of the rotating sound-emitting plate 3 and the meshing teeth 31 can be set according to strength requirements. The end shape of the meshing teeth 31 can be arc-shaped or pointed, and can be reinforced to ensure strength. When the outer ring 1 and the inner ring 2 rotate relative to each other, the meshing teeth 31 continuously mesh with the toothed grooves 12 to emit sound. After the rotation stops, the meshing teeth 31 remain engaged with a toothed groove 12 at the stop position, so that the outer ring 1 and the inner ring 2 will not rotate relative to each other at will. The elastic element 4 includes an elastic ring 41 with an opening and an elastic short rod 42. The rotating sound-generating plate 3 has a groove 32 for accommodating the elastic short rod 42. After being squeezed by the inner ring of the toothed groove 12, the elastic ring 41, which is elastically deformed, presses the meshing teeth 31 against the toothed groove 12 through the elastic short rod 42. One end of the inner ring 2 is provided with an inner cover plate 23. The inner cover plate 23 is integrally formed with the inner ring 2. One end of the outer ring 1 is provided with an outer cover plate 13. The outer cover plate 13 is integrally formed with the outer ring 1. The outer ring 1 and the inner ring 2 are circular in shape. The central hole 21 of the inner ring 2 is circular. Keyways and mounting holes for installation and connection can be provided on the outer ring 1 and the inner ring 2.
[0029] The rotating sound-generating plate 3 is provided with an anti-rotation stop 33 that cooperates with the limiting plate 22. The limiting plate 22 includes at least two limiting edges. Example 2:
[0030] See Figure 5 and Figure 6 As shown, a rotating shaft structure for emitting sound prompts includes an outer ring 1 and an inner ring 2 that can rotate relative to each other. The inner ring 2 has a central hole 21. A rotating sound-emitting plate 3 and an elastic element 4 are provided between the outer ring 1 and the inner ring 2. The outer ring 1 has a cavity 11 that accommodates the rotating sound-emitting plate 3 and the elastic element 4. The inner wall of the outer ring 1 has a ring of evenly arranged toothed grooves 12. The inner ring 2 has a limiting plate 22 for fitting the rotating sound-emitting plate 3. The rotating sound-emitting plate 3 has meshing teeth 31. When the outer ring 1 and the inner ring 2 rotate relative to each other, the meshing teeth 31 continuously mesh with the toothed grooves 12 to emit sound. The elastic element 4 includes an elastic ring 41 with an opening and an elastic short rod 42. The rotating sound-emitting plate 3 has a groove 32 that accommodates the elastic short rod 42. The elastic ring 41 presses the meshing teeth 31 against the toothed grooves 12 through the elastic short rod 42.
[0031] See Figure 6 As shown, the inner ring 2 has an inner cover plate 23 at one end. The inner cover plate 23 and the inner ring 2 are separate components. The outer ring 1 has an outer cover plate 13 at one end. The outer cover plate 13 and the outer ring 1 are separate components. The outer ring 1 and the inner ring 2 are polygonal in shape, and the central hole 21 of the inner ring 2 is polygonal, such as a quadrilateral or hexagon. The rotating sound-generating plate 3 has an anti-rotation stop 33 that cooperates with the limiting plate 22. The limiting plate 22 includes at least two limiting edges, such as quadrilateral edges or hexagonal edges.
