Description

Technical Field

[0001] This utility model relates to the field of rotary switch technology, specifically a rotary switch designed to prevent accidental activation. Background Technology

[0002] A rotary switch is a manual control element that uses rotation to turn circuits on and off, switch gears, or adjust parameters. It is widely used in household appliances, industrial equipment, instruments, and other applications. Its core function is to drive the internal mechanism through the mechanical rotation of the knob, thereby changing the circuit state.

[0003] The knobs of existing rotary switches are exposed and easily turned accidentally, which not only affects the normal operation of the equipment, but may also cause equipment failure and unnecessary damage in severe cases. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary switch to prevent accidental touch, comprising a base, a housing fixedly mounted on the top of the base, a limiting sleeve disposed inside the base, a transmission mechanism and a contact mechanism disposed sequentially from top to bottom inside the limiting sleeve, and a rotating sleeve rotatably mounted on the top of the limiting sleeve. The contact mechanism has pins at its bottom, which extend to the outside of the base. A connecting block is integrally formed on the top of the rotating sleeve, and a knob is mounted on the outside of the connecting block. The top of the inner wall of the housing has a plurality of first teeth arranged in a ring at equal intervals, and a groove is formed between adjacent first teeth. The outside of the knob has a plurality of second teeth that cooperate with the groove. An indicator is fixedly connected to the knob, and one end of the indicator has a plug rod. A circular hole is opened at the bottom of the plug rod, and a spring is installed inside the circular hole. The bottom of the spring abuts against the connecting block.

[0019] 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.

[0020] Please see Figures 1 to 7This utility model provides a technical solution: an anti-accidental touch rotary switch, including a base 1, a housing 2 fixedly installed on the top of the base 1, a limiting sleeve 8 disposed inside the base 1, the limiting sleeve 8 being used to limit the rotation of a rotating sleeve 7, making the limiting sleeve 8 more stable when rotating, and a transmission mechanism 9 and a contact mechanism 10 arranged sequentially from top to bottom inside the limiting sleeve 8. When the knob 3 is rotated, the knob 3 drives the connecting block 6 to rotate together, and the connecting block 6 causes the rotating sleeve 7 to rotate. The rotating sleeve 7 transmits power through the transmission mechanism 9, driving the contacts of the contact mechanism 10 to make contact or separate actions, thereby realizing the switching of the on and off states of the rotary switch circuit. The transmission mechanism 9 and the contact mechanism 10 are both existing technologies, so they will not be described in detail. The rotating sleeve 7 is rotatably installed on the top of the limiting sleeve 8. The bottom of the contact mechanism 10 is provided with a pin 5, which is used to connect to an external wire. The pin 5 extends to the outside of the base 1. The top of the rotating sleeve 7 is integrally formed. There is a connecting block 6, and a knob 3 is installed on the outside of the connecting block 6. The top of the inner wall of the outer shell 2 is provided with multiple first locking teeth 17 distributed in a ring at equal intervals. A groove 20 is formed between adjacent first locking teeth 17. The outside of the knob 3 is provided with multiple second locking teeth 19 that cooperate with the groove 20. The second locking teeth 19 are locked in the groove 20, which can fix the knob 3 and restrict its circumferential rotation, effectively preventing accidental rotation of the knob 3, ensuring that the knob 3 is always locked in the preset working position, and avoiding the normal operation of the equipment due to accidental contact. An indicator 4 is fixedly connected to the knob 3. One end of the indicator 4 is provided with a plug rod 11. A round hole 22 is opened at the bottom of the plug rod 11. A spring 14 is installed inside the round hole 22. The spring 14 is used to apply an upward pushing force to the knob 3 through the plug rod 11, so that the second locking teeth 19 are always in the groove 20 when no external force is applied, and the knob 3 can automatically reset after being pressed. The bottom of the spring 14 abuts against the connecting block 6.

[0021] Both the second locking tooth 19 and the first locking tooth 17 have an inclined surface 18 at one end. The inclined surface 18 is used to guide the second locking tooth 19, making it easier for the second locking tooth 19 to be aligned with the slot 20 and inserted.

[0022] The top of the connecting block 6 is provided with a insertion hole 12 for inserting the insertion rod 11. The connecting block 6 is provided with a limiting post 15, which is used to limit the spring 14 and prevent the spring 14 from shifting. The spring 14 is sleeved on the outside of the limiting post 15.

[0023] The insertion rod 11 is symmetrically provided with a first locking block 13 on its outer side. The first locking block 13 is used to fix the insertion rod 11 and the connecting block 6. The connecting block 6 is provided with a second locking block 16 on both sides. The second locking block 16 is used to fix the knob 3 and the connecting block 6.

[0024] The knob 3 has a mounting groove 21 at its bottom for the connecting block 6 to pass through. The mounting groove 21 is adapted to the connecting block 6. When the knob 3 is installed on the connecting block 6 through the mounting groove 21, the knob 3 can drive the connecting block 6 to rotate together.

[0025] Specifically, when it is necessary to rotate knob 3, press knob 3 down. Knob 3 drives the insert rod 11 and the second locking tooth 19 to move downward. When the insert rod 11 contacts the connecting block 6, the second locking tooth 19 has separated from the slot 20, and the insert rod 11 compresses the spring 14. Then, knob 3 can be rotated. After knob 3 is rotated, release knob 3. The spring 14 pops open and resets, causing the insert rod 11 to move upward. The insert rod 11 causes knob 3 to move upward, and knob 3 drives the second locking tooth 19 to move upward. Guided by the inclined surface 18, the second locking tooth 19 is engaged in the slot 20, thereby fixing knob 3 and preventing accidental rotation of knob 3.
