Detailed ways

Referring to Figures 1-4, the utility model provides a LED desk lamp with a rotating lamp head, which includes an LED lamp head 1 and a base 3, and the LED lamp head 1 is connected to the base 3 through a foldable telescopic bracket 2. This embodiment The telescopic support 2 used in the above is composed of two connecting rods. One end of the telescopic support 2 is hinged on the base 3, and the other end is provided with a rotary joint 4. The rotary joint 4 is hinged on the telescopic support 2. Set on the rotary joint 4 Shaft 40, the LED lamp head 1 is rotatably connected to the shaft 40, that is, the LED lamp head 1 can rotate around the hinge through the rotating joint 4, and can also rotate around the shaft 40, so that it can be adjusted both horizontally and vertically The LED lamp holder 1 can adjust the height by using the telescopic bracket 2 at the same time, and can adjust the lighting angle in multiple directions. It is convenient to use and operate, has a more practical structure, and has a wider application range.

As shown in Figure 5, in the above-mentioned structure, the shaft post 40 is provided with a protruding ring 41, and a ring groove cooperating with the protruding ring 41 is provided in the LED lamp cap 1 for clamping the LED lamp cap 1. When assembling, the protruding ring 41 is rotatably locked in the ring groove, so that the LED lamp holder 1 can rotate around the shaft 40 firmly. Preferably, a limit block 42 is also provided on the shaft column 40, and at the same time, a stopper is provided in the housing of the LED lamp head 1 at the connection with the rotating shaft. When the LED lamp head 1 rotates, the stopper blocks the limit block 42 to limit the LED The rotation of the lamp cap 1 means that the LED lamp cap 1 cannot rotate 360° circularly, so as to avoid twisting the wiring of the LED lamp cap 1 due to excessive rotation.

In the structure of the base 3 described above, the base 3 is built with a rechargeable battery, and the base 3 is provided with a control switch connected to the rechargeable battery, a charging plug and a power indicator light. In this embodiment, the base 3 used is an integrated structure with clips. The specific structure is that a splint 5 and an elastic member 6 are provided at the bottom of the base 3. The elastic member 6 is a torsion spring, and the middle position of the splint 5 is hinged on the At the bottom of the base 3, the elastic member 6 is installed on the hinge between the splint 5 and the base 3, so that the splint 5 and the base 3 form a clip structure, that is, the base 3 also has a clip function. Preferably, the base 3 and the splint 5 are respectively provided with anti-slip protrusions located inside the clamping portion of the clip. When in use, the base 3 can be directly clamped on the edge of the countertop, bookshelf, etc., which is flexible and convenient to use, and has a wider application range.

The above embodiments are only used to illustrate the technical solution of the utility model and not to limit it. Any modification or equivalent replacement that does not depart from the spirit and scope of the utility model shall be covered within the scope of the utility model technical solution.
