[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-2 As shown, a single-axis rotating adjustable lighting angle USB light includes a USB housing and a lamp housing that are rotatably mounted together.

[0023] The USB housing includes a USB plug 1, a rotating core top cover 2, a rotating core bottom cover 3, and a rotation damping ring 4. The rotating core bottom cover 3 and the rotating core top cover 2 are snapped together. One end of the USB plug 1 is snapped between the rotating core bottom cover 3 and the rotating core top cover 2. The other end of the rotating core bottom cover 3 and the rotating core top cover 2 is formed with a rotating core for rotating and mounting the lamp housing. The end of the rotating core top cover 2 near the lamp housing is integrally formed with a first semi-circular rotating core 21, and the end of the rotating core bottom cover 3 near the lamp housing is integrally formed with a second semi-circular rotating core 31. The first semi-circular rotating core 21 and the second semi-circular rotating core 31 are joined together to form the rotating core. The rotating core has a channel for installing positive and negative power lines. The rotation damping ring 4 is fitted on the outside of the rotating core and rotates and cooperates with the lamp housing.

[0024] The lamp housing includes a top cover 5, a bottom cover 6, a light-transmitting lampshade 7, and a PCB lamp board 8. The top cover 5 and the bottom cover 6 are snapped together, with one end rotatably mounted on the end of the USB shell. The top cover 5 near the USB plug 1 has a first rotating core cover 51 integrally formed, and the bottom cover 6 near the USB plug 1 has a second rotating core cover 61 integrally formed. The first rotating core cover 51 and the second rotating core cover 61 are assembled together and rotatably mounted on the outside of the rotating body. A rotation damping ring 4 is rotatably mounted inside the rotating body formed by the first rotating core cover 51 and the second rotating core cover 61. The rotation damping ring 4 can effectively support angular stability, keeping the lamp housing and the USB shell at a fixed angle without rotation when no external force is applied. The PCB lamp board 8 is snapped between the top cover 5 and the bottom cover 6. The light-transmitting lampshade 7 is embedded on the top cover 5 at the position of the LED on the PCB lamp board 8. The PCB lamp board 8 is electrically connected to the USB plug 1 through positive and negative power lines.

[0025] In this embodiment, the first semi-circular rotating core 21 is formed on one side edge of the rotating core top cover 2, the second semi-circular rotating core 31 is formed on one side edge of the rotating core bottom cover 3, the first rotating core cover 51 is formed on one side edge of the lamp housing top cover 5, and the second rotating core cover 61 is formed on one side edge of the lamp housing bottom cover 6. The lamp housing can rotate vertically by ±90° to a total of 180° relative to the USB plug 1, adjusting the lighting at any angle and improving its practicality during use.

[0026] like Figure 3-4 As shown, the content of this embodiment is largely the same as that of Embodiment 1, except that:

[0027] In this embodiment, the first semi-circular rotating core 21 is formed in the middle of the rotating core top cover 2, the second semi-circular rotating core 31 is formed in the middle of the rotating core bottom cover 3, the first rotating core cover 51 is formed in the middle of the lamp housing top cover 5, and the second rotating core cover 61 is formed in the middle of the lamp housing bottom cover 6. The lamp housing can rotate horizontally relative to the USB plug 1. The second semi-circular rotating core 31 and the second rotating core cover 61 are formed with matching tabs 9a and 9b. The tabs 9a and 9b limit the rotation of the lamp housing relative to the USB plug 1 to prevent the rotation from exceeding 360°, which would cause the positive and negative power lines connecting the USB plug 1 and the PCB lamp board 8 to twist and break, affecting the service life.

[0028] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.

[0029] Components not described in detail in this article are existing technologies.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
