Description

Technical Field

[0001] This utility model relates to the field of adjustment knob reset technology, specifically to a rotary adjustment knob reset mechanism. Background Technology

[0002] A "rotary control knob" generally refers to a control component that allows for adjustment by turning a circular or similar shape. Rotary control knobs serve different functions in different devices and scenarios: on audio equipment, they may be used to adjust volume or pitch; on stoves, they may be used to control the heat; on some tools or machines, such as a bench drill, they are used to adjust the spindle speed or feed rate; and on some lighting fixtures, they are used to adjust the brightness or color of the light.

[0003] Some existing rotary adjustment knobs have limit components during adjustment to allow users to more clearly know the rotation range. After the knob is rotated to a certain angle, the limit component applies resistance to the knob. After rotating a certain angle, the resistance must be overcome before it can continue to rotate, so that the user can accurately know the rotation angle. However, during the reset process, since the rotary adjustment knob does not have a reset function, manual reverse rotation to reset also requires overcoming resistance, resulting in a slow reset speed and some inconvenience in use.

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] Example 1

[0028] like Figure 1-11As shown, this utility model provides a rotary adjustment knob reset mechanism, including a housing 1, a base plate assembly 2 fixedly connected to the bottom of the housing 1, a knob assembly 3 rotatably connected inside the housing 1, a limit assembly 4 fixedly connected to the surface of the base plate assembly 2, a reset assembly 5 inserted inside the knob assembly 3, the reset assembly 5 including a reset button 51, a connecting post 52 fixedly connected to the top of the inner cavity of the reset button 51, a reset spring 53 movably sleeved on the surface of the connecting post 52, a connecting rod 54 movably sleeved on the inner wall of the lower end of the reset spring 53, a connecting plate 55 fixedly connected to the bottom of the connecting rod 54, a top of the connecting rod 54 fixedly connected to the bottom of the connecting post 52, a reset rod 56 fixedly connected to the top of one end of the connecting plate 55, and a sliding block 57 fixedly connected to one end of the reset rod 56.

[0029] In this embodiment, by pressing the reset button 51 downwards, the connecting post 52 causes the connecting rod 54 to move downwards under the pressure, while simultaneously compressing the reset spring 53. As the connecting rod 54 moves downwards, the connecting plate 55 causes the reset rod 56 to move the sliding block 57 to pull the locking block 46 downwards, thereby disengaging the locking block 46 from the limiting post 33. Under the action of the torsion spring 35, the rotary adjustment knob 31 is reset. Then, by releasing the reset button 51, the locking block 46 returns to the space between the limiting posts 33 under the action of the reset spring 53, making it easier to reset.

[0030] Example 2

[0031] like Figure 1-11As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the base plate assembly 2 includes a base plate 21, a first locking block 22 is fixedly connected to one side of the base plate 21, a second locking block 23 is fixedly connected to one side of the top of the base plate 21, and a mounting member 24 is fixedly connected to the top of the base plate 21. The interior of the mounting member 24 is slidably connected to the surface of the connecting rod 54, and the top of the mounting member 24 overlaps with the top of the return spring 53. The knob assembly 3 includes a rotary adjustment knob 31, a limit ring 32 is inserted into the bottom of the rotary adjustment knob 31, a limit post 33 is fixedly connected to the bottom of the limit ring 32, a first protrusion 34 is fixedly connected to the inner wall of the rotary adjustment knob 31, and a torsion spring 3 is overlapped on the surface of the first protrusion 34. 5. The surface of the torsion spring 35 overlaps with the inner wall of the rotary adjustment knob 31. The limiting component 4 includes a mounting box 41. The bottom of the mounting box 41 is fixedly connected to the top of the mounting component 24. Limiting plates 42 are fixedly connected to both sides of the inner cavity of the mounting box 41. A sliding plate 43 is slidably connected to the inner wall of the mounting box 41. A spring 44 is fixedly connected to one side of the sliding plate 43. The other end of the spring 44 is fixedly connected to the inner wall of the mounting box 41. A connecting block 45 is fixedly connected to the other side of the sliding plate 43. A locking block 46 is slidably connected to the surface of the connecting block 45. The surface of the locking block 46 overlaps with the surface of the limiting post 33. A sliding groove 47 is provided at the bottom of the locking block 46. The inner wall of the sliding groove 47 is slidably connected to the surface of the sliding block 57.

[0032] In this embodiment, during use, rotating the rotary adjustment knob 31 causes the limiting ring 32 to rotate. Simultaneously, the limiting post 33 pushes the locking block 46 to retract, causing the sliding plate 43 to compress the spring 44. When the limiting post 33 disengages from the locking block 46, the locking block 46 resets under the action of the spring 44, applying resistance to the next limiting post 33 again, so that the user can accurately know the rotation angle of the rotary adjustment knob 31.

[0033] Example 3

[0034] like Figure 1-11 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the outer shell 1 includes a shell 11, and a second protrusion 12 is provided on the surface of the shell 11 and on one side of the first protrusion 34, and the surface of the second protrusion 12 overlaps with the surface of the torsion spring 35.

[0035] In this embodiment, during the rotation process, the first protrusion 34 pushes one end of the torsion spring 35 to rotate, while the other end of the torsion spring 35 remains stationary under the limit of the second protrusion 12, thereby putting the torsion spring 35 into a stored state.

[0036] The working principle of the rotary adjustment knob reset mechanism will be explained in detail below.

[0037] like Figure 1-11As shown, during use, rotating the rotary adjustment knob 31 causes the limiting ring 32 to rotate. Simultaneously, the limiting post 33 pushes the locking block 46 to retract, compressing the sliding plate 43 and spring 44. When the limiting post 33 disengages from the locking block 46, the spring 44 causes the locking block 46 to reset, reapplying resistance to the next limiting post 33. This allows the user to accurately determine the rotation angle of the rotary adjustment knob 31. During rotation, the first protrusion 34 pushes one end of the torsion spring 35 to rotate, while the other end of the torsion spring 35 remains stationary under the limitation of the second protrusion 12. When the torsion spring 35 is in a charged state and the rotary adjustment knob 31 is reset, the reset button 51 is pressed down. Under the pressure, the connecting column 52 drives the connecting rod 54 to move down, while compressing the reset spring 53. As the connecting rod 54 moves down, the connecting plate 55 drives the reset rod 56, causing the sliding block 57 to pull the locking block 46 down, thereby disengaging the locking block 46 from the limiting column 33. Under the action of the torsion spring 35, the rotary adjustment knob 31 is reset. Then, the reset button 51 is released, and under the action of the reset spring 53, the locking block 46 returns to the space between the limiting columns 33, making it easier to reset.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
