Problems solved by technology
[0004] However, during the rotation of the first adapter 11 relative to the second adapter 29, the conductive wire is often scratched by the boss 18 in the middle of the first adapter 11, so that there is a hidden danger of disconnection in the lamp. At the same time, the boss 17, 18 and 19 are small in size, and the friction with the second adapter 29 is relatively large, which may easily lead to a large change in the original size and make the lamp head unable to be positioned

Embodiment Construction
[0014] see Figure 1 to Figure 2 , is a preferred embodiment of the lamp shaft device 100 of the present invention. The shaft device 100 includes a first adapter 60 and a second adapter 53 . The second adapter 53 is disposed at one end of a light pole 50 . The second adapter 53 and the light pole 50 can be manufactured separately or integrally formed. In this embodiment, the second adapter 53 is integrally formed on the light pole 50 . A conductive wire (not shown) passes through the first adapter 60 , the second adapter 53 and the light pole 50 to respectively connect the lamp holder (not shown) and the lamp socket (not shown) of the lamp.
[0015] The light pole 50 is composed of a first elongated shell 51 and a second shell 55 matched with the first shell 51 . The first housing 51 includes a longitudinal connecting portion 54 in the middle and receiving portions 52 at opposite ends of the connecting portion 54 . The second housing 55 is symmetrical to the first housing ...

The invention relates to a barring gear of a luminaire used for connecting a lamp cap and a lamp post, comprising a first adaptor connected with the lamp cap and a second adaptor connected with the lamp post; wherein, the first adaptor is equipped with a fixing part connected with the lamp cap and a pivot part connected with the fixing part, and an arc-shaped boss is arranged on the pivot part; the second adaptor is provided with a circular groove to accommodate the boss of the pivot part; the boss together with the second adaptor forms an arc clearance concyclic with the boss; and the arc ofthe clearance is longer than the half circumstance of the circle where the clearance is positioned to lead a conductor wire to pass through. In the barring gear of a luminaire of the invention, as the arc passing through the clearance is longer than the half circumstance, the conductor wire passing through the clearance does not contact with the boss, thus effectively preventing the conductor wire from being scraped in the process of rotation of the first adaptor.
Description
technical field [0001] The invention relates to a lamp rotating shaft device, in particular to a lamp rotating shaft device used for desk lamps. Background technique [0002] A desk lamp in the prior art usually includes a lamp base, a lamp post connected to the lamp base, and a lamp base connected to the lamp post. Wherein the lamp holder and the lamp holder are equipped with necessary electronic components, such as the lamp holder is provided with a transformer and a power line connected to the outside, and the lamp holder is provided with a light bulb or a lamp tube. The electronic components in the lamp holder are electrically connected with the electronic components of the lamp head through conductive wires, and the conductive wires are generally accommodated inside the lamp pole. In order to adjust the irradiation angle of the lamp head of the desk lamp to meet the needs of lighting in different directions, the lamp head is connected to the lamp post, and the lamp pos...
