Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.

[0026] Reference Figure 1-4As shown: A rocker potentiometer with a threaded adjustment structure includes a rocker assembly 14, a housing 44, a first rotary output assembly 23, a second rotary output assembly 22, a pressure plate 24, and a return spring 26. The first rotary output assembly 23 and the second rotary output assembly 22 are respectively mounted adjacent to each other on the outer side of the housing 44. The lower part of the rocker assembly 14 is disposed inside the housing 44, and the output ends of the rocker assembly 14 extend out of the housing 44 and are connected to the first rotary output assembly 23 and the second rotary output assembly 22. The return spring 26 is disposed at the bottom of the inner cavity of the housing 44, and the pressure plate 24 is correspondingly pressed on the upper surface of the return spring 26 and its position corresponds to the bottom of the rocker assembly 14.

[0027] The outer casing 44 includes a pressure cap 18, a housing 21, and a bottom cover 27. The pressure cap 18 is correspondingly disposed on the upper surface of the housing 21, and the bottom cover 27 is correspondingly disposed on the bottom of the housing 21. The four corners of the pressure cap 18, housing 21, and bottom cover 27 are all connected and fixed by a pin 15. The outer casing 44 has an opening for the rocker arm assembly 14 to move. The four sides of the pressure cap 18 are each formed with an upper bearing sleeve 16 that cooperates with the rocker arm assembly 14. The four sides of the upper surface of the housing 21 are each formed with a lower bearing sleeve 19 that corresponds to the upper bearing sleeve 16. The upper bearing sleeve 16 and the lower bearing sleeve 19 form a rotation support hole for the rocker arm assembly 14. The outer casing 44 includes a pressure cap 18, housing 21, and bottom cover. The four sides 27 are connected and fixed by a pin 15. This facilitates assembly and can also distribute the force applied by the rocker arm assembly 14 to the rotation support hole, thereby improving the service life of the outer casing 44.

[0028] The rocker assembly 14 includes a rocker structure 45, an upper rocker arm 12, and a lower rocker arm 13. Both the upper rocker arm 12 and the lower rocker arm 13 form a space for the rocker structure 45 to deflect. The rocker structure 45 includes a hollow outer bushing 11 and an inner adjusting shaft 10. The inner sidewall of the hollow outer bushing 11 is provided with an internal thread, and the outer side of the inner adjusting shaft 10 is provided with an external thread that mates with the internal thread. The inner adjusting shaft 10 passes through the hollow outer bushing 11. The bottom of the inner adjusting shaft 10 extends out of the hollow outer bushing. The inner adjusting shaft 10 extends outward from the hollow outer sleeve 11 and forms an adjusting slot 32. The lower two sides of the hollow outer sleeve 11 are rotatably connected to the lower rocker arm 13 via a first rotating shaft 43. One side of the upper rocker arm 12 is rotatably connected to a rotating support hole, and the other side is connected to a second rotating output assembly 22. One side of the lower rocker arm 13 is rotatably connected to a rotating support hole, and the other side is connected to the first rotating output assembly 23. In actual use, a tool is inserted into the adjusting slot 32, and the relative height of the inner adjusting shaft 10 within the hollow outer sleeve 11 is rotated to change the pressure applied by the pressure cap 33 to the pressure plate 24, thereby adjusting the pressure applied by the pressure plate 24 to the return spring 26. Users can adjust the pressure according to their own usage habits, ensuring a good control feel and improving the user experience.

[0029] Both the first rotary output assembly 23 and the second rotary output assembly 22 are provided with U-shaped mounting brackets 17 on the side of the outer casing 44. The first rotary output assembly 23 and the second rotary output assembly 22 are provided with upper protrusions 35 and lower protrusions 34 on opposite sides in the width direction. The upper part of one side of the U-shaped mounting bracket 17 in the width direction has a first abutting buckle block 36 that cooperates with the upper protrusion 35 and a buckle hole 46 that cooperates with the lower protrusion 34. The lower part of the side of the U-shaped mounting bracket 17 facing the outer casing 44 is provided with an elastic buckling arm 38. The housing 21 is provided with a second abutting buckle block 39 that cooperates with the elastic buckling arm 38 at the position corresponding to the elastic buckling arm 38. In this embodiment, the first rotating output component and the second rotating output component are fixed to the outer shell by a U-shaped mounting bracket. With the cooperation of the upper protruding buckle 35, the first abutting buckle 36, the lower protruding buckle 34 and the buckle hole 46, the installation stability of the first rotating output component and the second rotating output component with the U-shaped mounting bracket is ensured. The U-shaped mounting bracket is fixed to the outer shell by the engagement of the elastic fastening arm 38 with the second abutting buckle 39, which facilitates assembly and improves assembly efficiency.

[0030] The first rotary output assembly 23 and the second rotary output assembly 22 have multiple locating pins 40 that penetrate the U-shaped mounting bracket 17 on one side of the housing 21. The housing 21 is provided with locating pin slots 41 for the locating pins 40 to be inserted. By setting the locating pins 40 and locating pin slots 41 to cooperate, positioning can be achieved quickly during assembly, which improves both the accuracy and efficiency of installation.

[0031] A limiting protrusion 37 is formed on the side of the housing 21 facing the first rotating output component 23 and the second rotating output component 22, and a U-shaped mounting bracket 17 is formed with a limiting insertion hole 47 that is interference-fitted with the limiting protrusion 37.

[0032] The upper rocker arm 12, inserted into the rotary support hole, is provided with a second rotating shaft 31, which is shaped like a teardrop with a wider top and a narrower bottom. The lower rocker arm 13, inserted into the rotary support hole, is provided with a third rotating shaft 48, which is also shaped like a teardrop with a wider top and a narrower bottom. In this embodiment, the second rotating shaft of the upper rocker arm is shaped like a teardrop with a wider top and a narrower bottom, and the third rotating shaft 48 of the lower rocker arm 13 is shaped like a teardrop with a wider top and a narrower bottom. This reduces the contact area between the rotating shaft and the rotary support hole, thereby reducing the wear caused by excessive contact area and improving service life.

[0033] The inner wall of the housing 21 has a fitting guide groove 42 formed from top to bottom, and the outer side of the pressure plate 24 has a plurality of guide protrusions 25 that are correspondingly embedded in the fitting guide groove 42. Under the guidance and cooperation of the fitting guide groove 42 and the guide protrusions 25, the pressure plate 24 can stably realize the displacement change in the vertical direction, thereby improving the stability during operation.

[0034] A limiting protrusion 28 is formed in the middle of the upper surface of the bottom cover 27, which is inserted into the reset spring 26 to prevent the reset spring 26 from being displaced.

[0035] The four sides of the bottom cover 27 have upward-facing protrusions 29 corresponding to the positions of the pins 15. The upward-facing protrusions 29 are provided with first pin mounting holes 30 for the pins 15 to pass through and connect. By providing the upward-facing protrusions 29, after the embodiment is assembled, the lower surface of the pins 15 is higher than the lower surface of the bottom cover 27, thereby ensuring that the lower surface of the bottom cover 27 can fit and be fixed to the mounting platform during normal use.

[0036] Preferably, the first rotation output component 23 and the second rotation output component 22 are configured as contact sensors or non-contact sensors. This allows for the sharing of the main structure between contact and non-contact potentiometers, reducing mold costs.

[0037] The above embodiments illustrate only one implementation of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
