Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary switches, and in particular to a rotary switch with a child lock structure. Background Technology
[0002] Rotary switches are widely used in the field of electronic equipment control, but existing products have many problems.
[0003] In terms of safety, ordinary rotary switches lack child protection, and accidental operation by children may cause equipment malfunctions, leading to burns, fires, and other safety accidents, even endangering lives in medical devices. Operationally, the direct rotation method is prone to accidental activation; for example, when adjusting volume or playback progress, unintentional touches can change the switch's state, affecting usability. Regarding functionality and stability, adjustments lack precise control, and accidental rotation is easily caused by vibration or external forces; for example, in vehicle-mounted devices, bumps can cause parameters to malfunction. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a rotary switch with a child lock structure, based on the current state of the technology.
[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: a rotary switch with a child lock structure, comprising a rotary switch body, characterized in that the rotary switch body comprises:

[0012] The effects achieved by the above components are as follows: by setting the rotary switch body to include a housing, circuit board, stop block, rotor component and shaft core component, the shaft core component is unlocked by pressing and drives the rotor component to rotate, which greatly improves safety and prevents children from accidentally operating it and causing danger.

[0017] Preferably, a damping block is provided extending along the rotor component on the damping part, and a limiting block for limiting the rotation of the rotor component is provided extending along the damping block on the stop block.
[0018] The effects achieved by the above components are as follows: by setting a damping block extending along the rotor component on the damping part, and setting a limit block extending along the damping block on the rotor component for limiting the rotation of the rotor component: the rotation range is precisely limited, preventing the rotor component from being damaged due to excessive rotation, ensuring that the rotary switch works stably within the design range, improving reliability, extending the product service life, and ensuring stable operation of the equipment.
[0019] Preferably, the circuit board is provided with connection ports.

[0023] Compared with existing technologies, the advantages of this utility model are as follows: By setting a rotary switch body including a housing, circuit board, stop block, rotor component, and shaft core component, the positions and connections of each component and the operation mode of the shaft core component are clearly defined, which not only enhances safety and prevents accidental operation by children, but also optimizes the operation logic to reduce accidental touches, and the compact structure facilitates space utilization. The damping and adjustment parts on the rotor component, together with the elastic damping beads and the protrusions inside the housing, provide a good operating feel and increase rotational stability. The annular resistor layer on the circuit board and the pins of the adjustment part realize functional adjustment. The damping block and the limit block limit the rotation range and ensure stability.

[0041] By pressing the shaft core 6, the first rotating end 10 is disengaged from the locking part 7 and enters the rotating part 8, while the second rotating end 11 enters the rotor part 5. Then, the shaft core 6 is rotated, which will simultaneously drive the rotor part 5 to rotate.
[0042] By setting the rotary switch body 1 to include a housing 2, a circuit board 3, a stop block 4, a rotor 5, and a shaft core 6, the shaft core 6 can be pressed to unlock and drive the rotor 5 to rotate, which greatly improves safety and prevents children from accidentally operating it and causing danger.

The rotation of the rotor 5 drives the pins 17 of the adjustment part 13 to move on the annular resistor layer 16, changing the resistance value, thereby easily adjusting the function of electrical equipment, such as precisely adjusting the brightness of lights, motor speed, etc., to meet the needs of different scenarios.
[0047] A damping block 18 extends along the rotor component 5 on the damping part 12, and a limiting block 19 for limiting the rotation of the rotor component 5 extends along the damping block 18 on the stop block 4.

[0053] In this embodiment 2,
[0054] like Figures 1 to 4As shown, by setting up a rotary switch body 1 including a housing 2, a circuit board 3, a stop block 4, a rotor 5, and a shaft core 6, the positions and connections of each component and the operation mode of the shaft core 6 are clearly defined. This enhances safety to prevent accidental operation by children, optimizes the operating logic to reduce accidental touches, and the compact structure facilitates space utilization. The damping part 12 and the adjusting part 13 on the rotor 5, together with the elastic damping bead 14 and the protrusion 15 inside the housing 2, provide a good operating feel and increase rotational stability. The annular resistor layer 16 on the circuit board 3 and the pin part 17 of the adjusting part 13 realize functional adjustment. The damping block 18 and the limit block 19 limit the rotation range to ensure stability. The connection port 20 of the circuit board 3 facilitates circuit connection and enhances versatility.

[0055] In this embodiment 3,
[0056] As shown in Figure 1 Figure 4 As shown, when the rotary switch needs to be operated, the user presses down on the shaft core 6. The shaft core 6 moves downward against the elastic force of the elastic element 9, causing the first rotating end 10 to disengage from the locking part 7 of the stop block 4 and enter the rotating part 8. At the same time, the second rotating end 11 enters the rotor part 5. At this time, rotating the shaft core 6 causes the rotor part 5 to rotate via the second rotating end 11. The pin 17 on the adjusting part 13 of the rotor part 5 moves on the annular resistor layer 16 to achieve circuit adjustment. During rotation, the elastic damping bead 14 in the damping part 12 contacts the protrusion 15 of the housing 2, providing damping sensation. After rotating back to the initial position, releasing the shaft core 6 causes it to reset under the action of the elastic element 9, and the first rotating end 10 returns to the locking part 7, realizing the child lock function and preventing children from accidentally rotating the switch.
