Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, specifically to a rocker arm rotation structure and a lighting fixture. Background Technology

[0002] With the continuous advancement of technology, all kinds of lighting fixtures have begun to enter thousands of households, and people's requirements for adjusting the illumination angle of lighting fixtures are also constantly increasing. The rocker arm rotation structure is a rotation adjustment structure that is suitable for a wide range of lighting fixtures such as magnetic track lights, ordinary track lights, ceiling lights, chandeliers, wall lights, table lamps, and floor lamps.

[0003] Chinese Patent No. CN210035187U discloses a rocker arm lamp structure, which includes a wall box, a lamp body, several lamp arms, and several rotating joints. The wall box is rotatably connected to one end of a lamp arm near the wall box via the rotating joints. Adjacent lamp arms are rotatably connected via rotating joints. The end of a lamp arm away from the wall box is connected to the lamp body. The rotating joint includes an upper rotating cover, a lower rotating cover, and a locking element for locking the upper and lower rotating covers. The upper rotating cover has a first annular groove, and the lower rotating cover has a protruding ring for engaging with the first annular groove. The protruding ring extends into the first annular groove, and a silicone ring is installed in the first annular groove. A nylon ring is installed in a second annular groove. This utility model has a novel structure, reasonable design, is easy to use, simple to operate by hand, has good wear resistance, long service life, maintains good and stable friction in the rotating joints, allows for smooth rotation of the lamp arms, and can achieve stable mutual positioning, making the structure reliable.

[0004] However, in the above technical solution, the distance and position between the lamp body and the wall box can only be adjusted by rotating the joint and the lamp arm. However, in this structure, the cable needs to be threaded into the lamp arm, which makes it inconvenient to disassemble during later maintenance and installation. Utility Model Content

[0013] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] In this invention, the method of requiring cables to pass through two lamp arms is replaced by multiple cables spliced ​​together. The current path is formed by the cables located in the first and second lamp arms. The first and second lamp arms are connected to conductive contacts through spring pin connectors. At the same time, the conductive slip ring can maintain the current flow when the first and second lamp arms rotate. It has a relatively simple structure for installation and disassembly.

[0022] Example 1

[0023] like Figures 1-6 As shown, the present invention proposes a rocker arm rotation structure, including a base 1, a support 2, a first lamp arm 3 and a rotation connection assembly, with the support 2 connected to the base 1.

[0024] In an optional embodiment, the support base 2 is provided with a fourth connector 10 that is electrically connected to the first connector 4; the fourth connector 10 is connected to a cable that is connected to an external power supply device.

[0025] One end of the first lamp arm 3 is rotatably connected to the support base 2; the support base 2 has an annular mounting groove, a bearing is connected in the mounting groove, a connecting ring is connected on the bearing, and multiple screws pass through the first lamp arm 3 and are connected to the connecting ring, so as to maintain the connection with the support base 2 without affecting the rotation.

[0026] A rotating connection assembly is provided on the first lamp arm 3. The rotating connection assembly includes a first connector 4, a second connector 5, conductive slip rings 6 and a connecting cable 7. The stators of the two conductive slip rings 6 are connected to both ends of the first lamp arm 3. The two ends of the connecting cable 7 are electrically connected to the stators of the conductive slip rings 6. The first connector 4 and the second connector 5 are connected to the rotors of the two conductive slip rings 6.

[0027] The second lamp arm 8 is connected to a third connector 9 at one end, and the third connector 9 is electrically connected to the second connector 5; the second lamp arm 8 is provided with the same bearing and connecting ring as the support base 2 at one end to connect to the other end of the first lamp arm 3.

[0028] In an optional embodiment, the first connector 4 and the third connector 9 are male.

[0029] In an optional embodiment, the second connector 5 and the fourth connector 10 are female connectors.

[0030] In one optional embodiment, the male connector is a spring pin connector, and the female connector is a conductive contact that is adapted to the spring pin connector. The spring pin connector and the conductive contact are existing technologies commonly found in wristbands or smartwatches. The circuit can be connected by the contact between the two, which reduces the impact of wear caused by ordinary plug-in connectors.

[0031] In an optional embodiment, the first lamp arm 3 is a split structure, which is an upper and lower split structure that are connected radially along the first lamp arm 3; the split design allows the first lamp arm 3 to be easily and directly disassembled. When disassembling, removing part of it makes it easy to directly expose the entire cable for inspection or replacement, reducing maintenance and installation time.

[0032] Example 2

[0033] like Figures 1-6 As shown, the present invention proposes a lamp, including a rocker arm rotation structure as described in Embodiment 1.

[0034] In summary, when using this utility model, the operator connects the base 1 to the wall or wall embedded parts using screws. When the structure is in normal use, the operator can manually pull the first lamp arm 3 and the second lamp arm 8 to adjust the specific position of the lamp at one end of the second lamp arm 8 to achieve the desired effect. When the second lamp arm 8 is pulled to rotate, the bearing at one end of the second lamp arm 8 rotates. At the same time, the rotor of the conductive slip ring 6 rotates, maintaining the connection between the third connector 9 and the second connector 5, and maintaining the circuit connection between the two to continuously supply power to the lamp. The other end of the first lamp arm 3 also moves away when rotating. The rotor of the conductive slip ring 6 maintains the connection between the connecting cable 7 and the cable or power supply on the support base 2. The cables on the first lamp arm 3 and the second lamp arm 8 are spliced ​​together to form a complete circuit to transmit current to the lighting fixture.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
