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.

[0018] The present invention will now be further described with reference to the accompanying drawings.

[0019] This utility model provides the following technical solution: As attached Figure 1-6As shown, this utility model discloses a track socket adapter with a novel ball positioning structure 3, including an adapter body 1 and a power supply bracket 2. The power supply bracket 2 is rotatably mounted on the adapter body 1. The adapter body 1 is provided with the ball positioning structure 3. The power supply bracket 2 is provided with positioning holes 4 and guide grooves 5 corresponding to the ball positioning structure 3. Several positioning holes 4 are arranged in a circular array and evenly spaced on the power supply bracket 2. The guide grooves 5 are arranged between adjacent positioning holes 4 and connected to adjacent positioning holes 4. During the rotation of the power supply bracket 2, the ball positioning structure 3 slides in the guide grooves 5. When the power supply bracket 2 rotates to a preset position, the ball positioning structure 3 engages with the corresponding positioning hole 4, realizing the positioning of the power supply bracket 2. Specifically, in this design, the ball positioning structure 3 includes a ball and a ball spring 12. The ball is disposed at one end of the ball spring 12, and the other end of the ball spring 12 is fixed to the adapter body 1. Under the action of the ball spring 12, the ball always tends to engage with the positioning hole 4. When the power supply bracket 2 rotates, the ball slides within the guide groove 5. When the power supply bracket 2 rotates to the preset position, the ball, under the action of the ball spring 12, engages with the corresponding positioning hole 4, thus positioning the power supply bracket 2. Furthermore, the guide groove 5 ensures smoother ball movement. Simultaneously, the ball positioning structure 3 makes the rotation of the power supply bracket 2 more stable, preventing wobbling during rotation and improving the safety of the track socket adapter.

[0020] Furthermore, the adapter body 1 includes an adapter shell 6, an adapter base 7, and an inner pressure cover 8. An inner cavity is formed between the adapter shell 6 and the adapter base 7. A copper sheet assembly 9 is disposed within the inner cavity. A ball bearing positioning post 10 protrudes from the inner wall of the inner cavity on the adapter base 7. A through ball bearing positioning groove 11 is formed within the ball bearing positioning post 10. A ball bearing positioning structure 3 is disposed within the ball bearing positioning groove 11, with one end extending into the ball bearing positioning groove 11 and into the guide groove 5 on the power supply bracket 2. The inner pressure cover 8 is snap-fitted to the adapter base 7, pressing the copper sheet assembly 9 within the inner cavity and the ball bearing positioning structure 3 within the ball bearing positioning groove 11. Specifically, in this embodiment, the inner pressure cover 8 is fixedly connected to the adapter base 7 via a snap-fit ​​structure, which not only facilitates disassembly and installation but also ensures the stability of the various components within the inner cavity. The inner pressure cover 8 is designed to effectively prevent dust and moisture from entering the inner cavity, protect the copper sheet assembly 9 and the ball positioning structure 3 from external environmental interference, and extend the service life of the track socket adapter.

[0021] Furthermore, the depth of the guide groove 5 is less than the depth of the positioning hole 4, and the width of the guide groove 5 is less than the inner diameter of the positioning hole 4. Specifically, in this embodiment, the design of the guide groove 5 allows the ball to be constrained during sliding, preventing it from detaching from the guide groove 5. Simultaneously, the depth of the guide groove 5 being less than the depth of the positioning hole 4 ensures the ball is more securely engaged in the positioning hole 4, preventing it from easily dislodging due to external forces. Additionally, the width of the guide groove 5 being less than the inner diameter of the positioning hole 4 also ensures the ball fits tightly against the inner wall of the positioning hole 4, further improving the positioning stability of the power supply bracket 2. This design not only improves the safety of the track socket adapter but also ensures the smoothness and stability of the power supply bracket 2 during rotation, providing users with a more convenient and safer power experience.

[0022] Furthermore, the ball positioning structure 3 includes a spring 12 and a ball body 13. One side of the ball body 13 extends into the spring 12 and abuts against it, while the other side extends out of the ball positioning groove 11 and into the guide groove 5. Specifically, in this embodiment, the ball body 13 maintains a tendency to engage with the positioning hole 4 under the action of the spring 12. This design makes the ball positioning structure 3 more sensitive and reliable. When the power supply bracket 2 rotates, the ball body 13 slides smoothly in the guide groove 5. Once the power supply bracket 2 rotates to the preset position, the ball body 13 quickly engages with the corresponding positioning hole 4 under the action of the spring 12, achieving precise positioning of the power supply bracket 2. This cooperative design of the ball positioning structure 3 and the guide groove 5 not only improves the stability of the rotation of the power supply bracket 2 but also effectively avoids safety hazards caused by shaking, further improving the performance and user experience of the track socket adapter.

[0023] Furthermore, the adapter base 7 is provided with a snap-fit ​​end 14, and the inner pressure cover 8 is provided with a pressure cover groove 15 corresponding to the snap-fit ​​end 14. The snap-fit ​​end 14 extends into the pressure cover groove 15 and snaps into the adapter base 7. Specifically, in this embodiment, the cooperative design of the snap-fit ​​end 14 and the pressure cover groove 15 makes the connection between the adapter base 7 and the inner pressure cover 8 more secure and reliable. During installation, simply align the snap-fit ​​end 14 with the pressure cover groove 15 and press gently to achieve the snap-fit ​​connection between the adapter base 7 and the inner pressure cover 8, greatly simplifying the installation steps and improving installation efficiency. At the same time, this snap-fit ​​connection method also facilitates the user's disassembly and maintenance of the track socket adapter when needed, providing great convenience to the user.

[0024] Furthermore, the copper plate assembly 9 includes a live wire copper plate 16, a neutral wire copper plate 17, and a ground wire copper plate 18. A corresponding contact piece 19 is provided within the power supply bracket 2, with one end of the contact piece 19 extending into the inner cavity and plugged into the copper plate assembly 9 for fixation. Specifically, in this embodiment, the arrangement of the live wire copper plate 16, neutral wire copper plate 17, and ground wire copper plate 18 meets the three-phase power supply requirements of the track socket adapter, ensuring the safety and stability of power use. The design of one end of the contact piece 19 extending into the inner cavity and plugged into the copper plate assembly 9 not only makes the connection between the power supply bracket 2 and the copper plate assembly 9 more robust and reliable, but also facilitates the user's disassembly and replacement of the power supply bracket 2 when needed, improving the flexibility and practicality of the track socket adapter. At the same time, this plug-in fixed connection method greatly simplifies the installation steps, improves installation efficiency, and provides users with a more convenient installation experience.

[0025] Furthermore, the live wire copper sheet and the neutral wire copper sheet are arranged symmetrically. Both the live wire copper sheet 16 and the neutral wire copper sheet 17 have copper clamp portions 21. Each copper clamp portion 21 has an upper clamping arm 22, a lower clamping arm 23, and a side clamping arm 24. The side clamping arm 24 is located on one side of the copper clamp portion 21 near the center position between the live wire copper sheet 16 and the neutral wire copper sheet 17. A clamping groove 25 is formed between the upper clamping arm 22, the lower clamping arm 23, and the side clamping arm 24. Specifically, in this embodiment, the symmetrical arrangement of the live wire copper sheet 16 and the neutral wire copper sheet 17 not only ensures the balance of power supply but also improves the overall structural strength of the copper sheet assembly 9. The design of the copper clamp portion 21 enables the copper sheet to firmly clamp the wire, preventing the wire from loosening or falling off, and ensuring the stability and safety of current transmission. The clamping groove 25 formed between the upper clamping arm 22, the lower clamping arm 23 and the side clamping arm 24 provides a suitable clamping space for the wire, so that the wire can be tightly and evenly clamped between the copper sheets, further improving the efficiency of current transmission.

[0026] Furthermore, the grounding copper sheet 18 has a grounding copper clamp 26, which consists of two opposing grounding clamp arms 27. Each grounding clamp arm 27 has an upper arm 28 and a lower arm 29, which are spaced apart. Both the upper arm 28 and the lower arm 29 have perforated holes 30. Specifically, in this embodiment, the design of the grounding copper clamp 26 allows the grounding copper sheet 18 to firmly clamp the grounding wire, preventing it from loosening or falling off, thus ensuring electrical safety and stability. The spacing between the upper arm 28 and the lower arm 29 provides sufficient clamping space for the wire, while the perforated holes 30 reduce the weight of the grounding copper sheet 18, making the entire copper sheet assembly 9 lighter. In addition, the perforated holes 30 also serve a heat dissipation function, helping to reduce the temperature of the copper sheet assembly 9 during operation and extending its service life. The design of this grounding copper clip 26 not only improves the safety of the rail socket adapter, but also enhances its practicality and durability, providing users with more reliable and safer power protection.

[0027] Furthermore, a limiting rib 31 is provided between the upper arm portion 28 and the lower arm portion 29. Specifically, in this embodiment, the provision of the limiting rib 31 further enhances the structural strength of the ground wire copper clamp portion 26, making the ground wire copper sheet 18 more stable and reliable when clamping the ground wire.

[0028] Furthermore, each of the copper sheet assemblies 9 is provided with a corresponding slot structure 20, into which the contact piece 19 extends and is inserted and fixed to the copper sheet assembly 9. Specifically, in this embodiment, the slot structure further enhances the connection stability between the contact piece 19 and the copper sheet assembly 9. The shape and size of the slot structure match the contact piece 19, ensuring that the contact piece 19 can be accurately and firmly inserted into the slot, avoiding safety hazards caused by unstable connection. At the same time, the slot structure design also facilitates the user to disassemble and replace the power supply bracket 2 when needed, improving the maintainability and practicality of the track socket adapter.
