[0001] This utility model relates to the field of household appliance technology, specifically to a track socket adapter with a novel knob ring structure. Background Technology

[0002] In the prior art, the knob ring on the track socket adapter is usually a one-piece solid structure. The knob ring is in direct contact with the adapter body shell. During rotation, the friction between adjacent parts is relatively large. After long-term use, wear is likely to occur, causing the knob ring to loosen and wobble, and the feel to deteriorate. Utility Model Content

[0003] In view of this, the present invention provides a track socket adapter with a novel knob ring structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A track socket adapter with a novel knob ring structure includes an adapter body, a rotatable knob ring mounted on the adapter body, and a power supply component electrically connected to the track socket and mounted on one side of the adapter body. The adapter body contains a rocker arm, and the knob ring has a ramp transmission part connected to the rocker arm. The knob ring includes an inner ring and an outer ring, and the ramp transmission part is formed by the inner ring protruding toward the rocker arm. The inner ring and the outer ring are spaced apart.

[0006] Preferably, the inner wall of the outer ring of the knob ring near the adapter body is recessed to form an annular guide step, and the adapter body protrudes to form a connecting end corresponding to the annular guide step, and the connecting end is guided and engaged with the annular guide step.

[0007] Preferably, the power-gathering component includes a power-gathering base and a power-gathering bracket. The power-gathering base is fixedly connected to the adapter body, and the power-gathering bracket is rotatably disposed between the power-gathering base and the adapter body. After the power-gathering component is inserted into the track socket, rotating the adapter body causes the power-gathering base to rotate and disengage from the power-gathering bracket to achieve electrical connection with the track socket. A jump board is provided on the power-gathering base, and a swing arm is movably connected to the jump board. During the swinging process driven by the jump board transmission part, the swing arm drives the jump board to swing to achieve circuit on / off control.

[0008] Preferably, the springboard transmission part has a transmission groove, and the swing rod partially extends into the transmission groove and is connected to the springboard transmission part for limiting. Rotating the knob ring drives the swing rod through the springboard transmission part, thereby controlling the swing of the springboard and controlling the circuit on / off of the adapter.

[0009] Preferably, a conductive sheet assembly is provided on the portion of the power-feeding base that extends into the adapter body. The conductive sheet assembly includes a conductive sheet and a conductive sheet cover. A swing arm movable groove is formed on one side of the conductive sheet cover. The swing arm is swayably disposed in the swing arm movable groove, and one end of the swing arm passes through the swing arm movable groove and connects to the jump plate.

[0010] Preferably, the power base has a placement groove, the conductive sheet is placed in the placement groove, the conductive sheet cover seals and positions the placement groove, and the conductive sheet cover is snap-fitted to the power base bracket.

[0011] Preferably, an adapter panel is also provided inside the knob ring. A stepped portion protrudes from the inner wall of the inner ring of the knob ring.

The adapter panel protrudes towards the adapter body to form a panel positioning end. A screw is provided between the panel positioning end and the adapter body and is fixed by the screw.

[0012] The beneficial effects of this utility model are as follows: the knob ring is an injection-molded one-piece structure. The inner ring and outer ring of the knob ring are connected as a whole by a connecting bridge structure. The connecting bridge is evenly distributed in the gap between the inner ring and the outer ring along the circumference. This not only ensures the integrity and strength of the overall structure of the knob ring, but also reduces the contact area between the inner ring, the outer ring and the adapter body, reduces the friction when the knob ring rotates, reduces the amount of wear during long-term rotation, effectively slows down the aging and loosening of the components, and extends the service life of the knob ring.

[0018] 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.

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] This utility model provides the following technical solution:

[0021] As attached Figure 1-4 As shown, this utility model discloses a track socket adapter with a novel knob ring structure, including an adapter body 1, a knob ring 2 rotatably disposed on the adapter body 1, and a power supply component disposed on one side of the adapter body 1 and electrically connected to the track socket. The adapter body 1 is provided with a swing rod 3, and the knob ring 2 is provided with a springboard transmission part 4. The springboard transmission part 4 is connected to the swing rod 3. The knob ring 2 includes an inner ring part 5 and an outer ring part 6. The springboard transmission part 4 is formed by the inner ring part 5 protruding towards the swing rod 3, and the inner ring part 5 and the outer ring part 6 are spaced apart. Specifically, in this design, the knob ring 2 is an injection-molded one-piece structure. The inner ring 5 and the outer ring 6 on the knob ring 2 are connected as a whole by a connecting bridge structure. The connecting bridge is evenly distributed in the gap between the inner ring 5 and the outer ring 6 along the circumference. This ensures the integrity and strength of the overall structure of the knob ring 2, while also reducing the contact area between the inner ring, the outer ring and the adapter body. This reduces the friction when the knob ring rotates, reduces the amount of wear during long-term rotation, effectively slows down the aging and loosening of the components, and extends the service life of the knob ring.

[0022] Furthermore, an annular guide step 7 is formed on the inner wall of the outer ring portion 6 of the knob ring 2 near the adapter body 1, and a corresponding connecting end 8 is formed on the adapter body 1. The connecting end 8 is guided and engaged with the annular guide step 7. Specifically, in this embodiment, the radial movement of the knob ring 2 during rotation can be limited by the guiding engagement between the annular guide step 7 and the connecting end 8, ensuring that the knob ring 2 always rotates stably around a preset axis without any rotational deviation or jamming. The user's operation and rotation feel are also smoother and more uniform.

[0023] Furthermore, the power-gathering component includes a power-gathering base 9 and a power-gathering bracket 10. The power-gathering base 9 is fixedly connected to the adapter body 1, and the power-gathering bracket 10 is rotatably disposed between the power-gathering base 9 and the adapter body 1. After the power-gathering component is inserted into the track socket, rotating the adapter body 1 causes the power-gathering base 9 to rotate and disengage from the power-gathering bracket 10, thus achieving an electrical connection with the track socket. A jump plate 11 is provided on the power-gathering base 9, and the swing rod 3 is movably connected to the jump plate 11. During the swinging process driven by the jump plate transmission part 4, the swing rod 3 drives the jump plate 11 to swing, thereby achieving circuit on / off control. Specifically, in this embodiment, when it is necessary to connect or disconnect the power supply of the track socket, rotating the knob ring 2 will push the swing rod 3 to swing through the jump plate transmission part 4. The bottom end of the swing rod 3 directly acts on the jump plate 11 of the power-gathering component, driving the jump plate 11 to complete the corresponding swinging action. There is no need to transmit power through multiple stages of transmission, resulting in less power transmission loss, more direct control action, and clearer feedback when the user rotates the knob. Compared to traditional multi-stage transmission switch structures, this design reduces the number of transmission components, lowers the impact of accumulated machining tolerances on transmission performance, controls manufacturing costs, and further reduces the probability of component wear and jamming after long-term use, thus improving the stability and lifespan of the adapter's on / off control. Simultaneously, the two ends of the lever 3 directly connect to the spring plate transmission part 4 at the knob ring 2 and the spring plate 11 at the power take-up base 9, respectively. During assembly, no additional positioning or fixing of the lever 3 is required; it only needs to be placed within its corresponding movement space to function normally. This further simplifies the overall assembly process of the adapter and adapts to the batch assembly requirements of automated production lines.

[0024] Furthermore, a transmission groove 12 is formed on the springboard transmission part 4. The swing rod 3 partially extends into the transmission groove 12 and is limited to the springboard transmission part 4. Rotating the knob ring 2 drives the swing rod 3 through the springboard transmission part 4, thereby controlling the swing of the springboard 11 and controlling the circuit on / off of the adapter. Specifically, in this embodiment, after the swing rod 3 extends into the transmission groove 12, the groove wall can limit the range of motion of the swing rod 3, preventing the swing rod 3 from coming off or deviating during transmission, further improving the reliability of the transmission fit. When the user rotates the knob ring 2 to drive the springboard transmission part 4 to rotate, the side wall of the transmission groove 12 directly pushes the swing rod 3 to swing in a preset direction, without slippage or force misalignment, further enhancing the stability of power transmission. This groove-type fit structure does not require additional snap-fit ​​fixing to the end of the swing rod 3, making parts processing more difficult. During assembly, the swing rod 3 only needs to be directly inserted into the transmission groove 12 to be in place, without adding additional assembly steps, and is suitable for existing mass production process requirements. Meanwhile, the transmission groove 12 will continuously limit the movement of the rocker arm 3 during long-term use. Even if the rocker arm 3 is subjected to repeated alternating forces, it will not disengage from the transmission position, effectively extending the service life of the entire switch transmission structure.

[0025] Furthermore, a conductive sheet assembly is provided on the portion of the power base 9 that extends into the adapter body 1. The conductive sheet assembly includes a conductive sheet 13 and a conductive sheet cover 14. A swing arm movable groove 15 is formed on one side of the conductive sheet cover 14. The swing arm 3 is swayably disposed within the swing arm movable groove 15, and one end of the swing arm 3 passes through the swing arm movable groove 15 and connects to the jump plate 11. Specifically, in this embodiment, the conductive sheet cover 14 can both press and fix the conductive sheet 13 to the corresponding position of the power base 9 through its own structure, ensuring the stability of the conductive connection, and can also integrally form a space for the swing arm 3 to move, eliminating the need for an additional separate swing arm 3 limiting bracket, further reducing the number of parts inside the adapter and simplifying the internal assembly process. When the swing arm 3 swings within the swing arm movable groove 15, the groove wall can limit the swing path of the swing arm 3, preventing the swing arm 3 from deviating and touching surrounding live parts during swing, thus improving the accuracy of the swing action and enhancing the electrical insulation safety inside the adapter. After passing through the swing arm movable slot 15, the swing arm 3 directly connects to the lower jump plate 11. The transmission path is not obstructed or interfered with by any additional structure, ensuring smooth power transmission throughout the entire process without any jamming or transmission loss, further guaranteeing the sensitivity and reliability of the circuit on / off control. The opposite side walls of the swing arm movable slot 15 protrude to form a rotating shaft. Corresponding rotating holes or slots are provided on the swing arm, allowing the swing arm to engage with the rotating shafts.

[0026] Furthermore, a placement groove 16 is formed on the power base 9, and the conductive sheet 13 is placed in the placement groove 16. The conductive sheet cover 14 seals and positions the placement groove 16, and the conductive sheet cover 14 is snap-fitted to the power base 9 bracket. Specifically, in this embodiment, the placement groove 16 can pre-position and limit the conductive sheet 13, preventing displacement or misalignment of the conductive sheet 13 during installation and improving assembly accuracy. After the conductive sheet cover 14 is sealed on the outside of the placement groove 16, it is directly connected and fixed to the power base 9 through the snap-fit ​​structure, without the need for additional screws, adhesives, or other fixing methods. This further simplifies the assembly steps of the conductive sheet assembly. Assemblers only need to press it into place to complete the fixation, greatly improving assembly efficiency and adapting to automated batch assembly operations. The snap-fit ​​connection structure has stronger fixing reliability and will not loosen or detach after long-term use. It can continuously maintain the pressing and positioning effect on the conductive sheet 13, ensuring the stability of the conductive connection and reducing the probability of power outages or poor contact failures during adapter use.

[0027] Furthermore, an adapter panel 17 is also provided inside the knob ring 2. A stepped portion 18 protrudes from the inner wall of the inner ring portion 5 of the knob ring 2. One side of the adapter panel 17 abuts against the stepped portion 18 and is in a limiting contact with the knob ring 2. The adapter panel 17 protrudes towards the adapter body 1 to form a panel positioning end 19. A screw is provided between the panel positioning end 19 and the adapter body 1 and the screw is used for connection and fixation. Specifically, in this embodiment, the adapter panel 17 serves as an axial limiting structure for the knob ring 2. Together with the stepped portion 18 on the inner wall of the inner ring portion 5, it can limit the axial movement range of the knob ring 2, preventing axial movement of the knob ring 2 during rotation, further improving the stability of the knob ring 2's rotation, and providing a better user operating feel. After the adapter panel 17 is fixed to the adapter body 1 with screws, the stepped portion 18 can hold the knob ring 2 against it. This eliminates the need for additional axial limiting parts such as axial retaining rings or retaining rings, reducing the number of parts and simplifying the assembly process. Simultaneously, the panel itself can cover the opening of the adapter body 1, protecting the internal structure and preventing dust and moisture from entering the adapter body 1 and affecting the operational stability of the live components, thus improving the overall insulation performance of the adapter. In this installation method, the knob ring 2 is clamped between the adapter body 1 and the adapter panel 17. After assembly, the axial clearance is uniform, preventing the knob ring 2 from being too tight to rotate or too loose to wobble or misalign, ensuring a stable and smooth rotation feel.
