Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, an embodiment of the lamp connecting structure of the present invention is provided:

a lamp connecting structure comprises a lamp arm 2, a lamp holder 1, a connecting piece 4, a shielding piece 3 and a lamp holder fixing piece 5.

The front end connecting part of the lamp arm 2 is divided into a first connecting part 21 and a second connecting part 22, the first connecting part 21 is arranged at the rightmost end, the cross section of the first connecting part 21 is a regular octagon, the second connecting part 22 is arranged at the left side of the first connecting part 21, and the side surface of the second connecting part 22 is provided with a lamp arm external thread 23. The rightmost end of the front end of the first connecting part 21 is also provided with pins 24, and the pins 24 are four in total and arranged in a rectangle.

The base fixing member 5 is provided at the bottom with a base fixing member first external thread 53 capable of fixing the base fixing member 5 to the lamp base 1. The lamp holder fixing member 5 is provided with a connection groove 51 at the top, a second external screw 54 of the lamp holder fixing member is provided outside the connection groove 51, and four insertion holes 52 adapted to the pins 24 are provided at the bottom of the connection groove 51, and the four insertion holes 52 are arranged in a rectangular shape.

The connector 3 is provided with a connector internal thread 41 on the inside and the shield 3 is provided with a shield internal thread 31 on the inside. Both the connector internal thread 41 and the shield internal thread 31 are adapted to the lamp arm external thread 23.

When fixed, lamp stand mounting 5 fixes on lamp stand 1 earlier, then on with shielding piece 3 screw in lamp arm 2, then with connecting piece 4 screw in lamp arm 2 on, at this moment, during the screw in, with shielding piece 3 toward lamp arm 2 left end screw in a lot of for connecting piece 4 bottom screw in lamp arm external screw thread 23 right-hand member. The lamp arm 2 is then electrically connected to the lamp holder 1 by inserting the pins 24 into the insertion holes 52. At this time, the first connecting portion 21 of the lamp arm 2 is inserted into the connecting groove 51, and the lamp arm 2 is restrained by the connecting groove 51. Then the connecting piece 4 is rotated to make the bottom of the connecting piece 4 tightly attached to the lamp holder 1, and then the shielding piece 3 is rotated downwards to tightly attach to the lamp holder 1, thereby completing the installation process.

1, the purpose of switching is to facilitate modularization of the lamp part and also enhance safety by using the pins 24 and the jacks 52.

2, the first connecting part 21 and the connecting groove 51 which are in the shape of a regular octagon can limit the lamp arm 2, and the lamp arm 2 cannot be screwed on the premise of not unscrewing the connecting piece 4. Thereby being safe, firm and stable.

The reason why the shielding member 3 is additionally used instead of designing the shielding member 3 and the connecting member 4 as a whole is that the connecting member 4 needs to be made of a more durable and more stable material, the shielding member 3 is not used, the weight and the bearing capacity of the lamp arm 2 are different, the required connecting member 4 is also different, and the cost can be saved by providing the shielding member 3 instead of a part of the connecting member 4.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
