Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a gear transmission type track socket adapter. Background Art

[0002] The track-type socket includes a track and several adapters slidably arranged on it. The track is provided with a conductive socket electrically connected to the power supply line, and the adapter has a conductive plug and a socket. When using the track-type socket, the conductive plug of the adapter is inserted into the conductive socket of the track plate and electrically contacts the conductive socket. In this way, when the plug of an electrical appliance is inserted into the socket of the adapter, the electrical appliance can draw power from the adapter.

[0003] The existing adapter structure still has shortcomings: For example, the technical solution disclosed in Chinese patent CN201921086035.6 (a quick wiring socket): the wiring plugs on the positioning column include a live wire plug, a neutral wire plug and a ground wire plug, wherein the live wire plug and the neutral wire plug are located on the same side, and the ground wire plug is set away from the live wire plug. The above technical solution has an unreasonable structural design: (1) The live wire plug and the neutral wire plug are located on the same side, resulting in a thicker portion of the entire adapter inserted into the track, so the track must also be made thicker, which is inconvenient to use; (2) The adapter lacks a positioning function when it is rotated and installed in place, and it is easy to make misjudgments based on personal experience; (2) The adapter is easy to loosen after being installed on the track, which is of poor practicality. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a gear-driven track socket adapter which has a reasonable structural design, can reduce the thickness of the adapter, has reliable positioning, is easy to use and has good practicality.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a gear-driven track socket adapter, comprising a base and a shell, wherein a rotating ring, a first conductive plug and a second conductive plug are arranged in the base, at least one limiting slot is arranged at the upper end of the rotating ring, and a driving protrusion is integrally arranged on the inner wall surface of the shell aligned with each limiting slot position, and the driving protrusion is inserted into the aligned limiting slot;

[0006] A gear transmission assembly is provided between the rotating ring, the first conductive plug and the second conductive plug, and the rotating ring drives the first conductive plug and the second conductive plug to rotate through the gear transmission assembly;

[0007] A positioning protrusion is provided at a local position of the inner wall surface of the rotating ring, a positioning groove is provided at a position below the positioning protrusion on the inner bottom surface of the base, a positioning spring is provided in the positioning groove, and the positioning spring is partially connected to the positioning protrusion;

[0008] The bottom of the base is integrally provided with an insert protection bracket, and the side of the insert protection bracket is provided with a plurality of elastic positioning buckles.

[0009] The utility model is further configured as follows: the gear transmission assembly includes a first rotating pin, a second rotating pin, a first gear and a second gear; the lower end of the first rotating pin is fixedly connected to one end of the first conductive plug, and the first gear is fixedly sleeved on the upper end of the first rotating pin; the lower end of the second rotating pin is fixedly connected to one end of the second conductive plug, and the second gear is fixedly sleeved on the upper end of the second rotating pin;

[0010] The rotating ring is integrally provided with driving teeth, and the first gear and the second gear are both meshed and driven with the driving teeth on the rotating ring;

[0011] The lower end surfaces of the first conductive plug and the second conductive plug are flush.

[0012] The utility model is further configured as follows: a first conductive rod is arranged in the first rotating pin, the lower end of the first conductive rod is electrically connected to the first conductive plug, the upper end of the first conductive rod is sleeved with a first conductive bracket, and the first conductive bracket is integrally provided with a first conductive socket at an end facing away from the first conductive rod; a second conductive rod is arranged in the second rotating pin, the lower end of the second conductive rod is electrically connected to the second conductive plug, the upper end of the second conductive rod is sleeved with a second conductive bracket, and the second conductive bracket is integrally provided with a second conductive socket at an end facing away from the second conductive rod.

[0013] The utility model is further configured as follows: a grounding metal plug is arranged between the first conductive plug and the second conductive plug, a plug through hole is arranged on the inner bottom surface of the base in alignment with the grounding plug position, the lower end of the grounding metal plug is inserted into the plug through hole, and the upper end of the grounding metal plug is sleeved with a grounding conductive plug sleeve.

[0014] The utility model is further configured as follows: the active tooth is arranged on the inner wall surface of the rotating ring or on the upper end surface of the rotating ring or on the lower end surface of the rotating ring; the first gear and the second gear are both full gears or both side gears.

[0016] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model has a reasonable structural design. When the user rotates the shell, the shell drives the rotating ring to rotate through the driving protrusion.

The rotating ring and the base are positioned and matched by the positioning spring and the positioning protrusion, so that the user has a greater change in hand feeling, which plays a role in prompting the rotation to be in place, and does not completely rely on personal experience, avoids misjudgment, ensures that the adapter is installed in place, and improves the user experience; and the elastic positioning structure has a certain positioning function, which can prevent the problem of easy loosening between the rotating ring 3 and the base 1 during use, and the positioning is reliable and easy to use.

[0018] The elastic positioning buckle arranged on the side of the bottom insert protection bracket of the base can ensure that the adapter is reliably connected to the track after being installed on the track, and is not easy to loosen or fall off, and has good practicality.
