[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 6As shown: a rotatable expansion plug board, including a plug board seat 1, a plug assembly 2 installed in a boss 301 with an inner cavity formed on the back plate 3 of the plug board seat 1, and the positive and negative poles of its pins 201 are interconnected with the circuit components inside the plug board seat 1. The plug assembly 2 can rotate relative to the plug board seat 1 in the boss 301, so that the plug board seat 1 can be installed in different indoor environments.

[0025] Furthermore, the rotation of the plug assembly 2 is mainly achieved through the rotating seat 202 provided therein; Figure 3 , Figure 5 As shown, the inner wall of the above-mentioned boss 301 protrudes to form a circle of convex edge 311, and a semi-circular arc-shaped limiting groove 321 is opened on the convex edge 311. After the rotating seat 202 is inserted into the boss 301 from the outside and abuts against one side of the convex edge 311, a limiting tooth 212 at the edge of the rotating seat 202 will be located in the limiting groove 321. Since the limiting tooth 212 is restricted by the left and right ends of the limiting groove 321, the plug assembly 2 as a whole can only rotate within the range of 0°-180°.

[0026] Furthermore, after the above-mentioned plug assembly 2 and the plug board seat 1 rotate relative to each other, positioning is required to ensure the stability of the structures of the two. Therefore, the plug assembly 2 also has a positioning plate 203; during the assembly process of the present design, when the above-mentioned rotating seat 202 is inserted into the boss 301 from the outside of the back plate 3, the positioning plate 203 is also inserted into the boss 301 from the inside of the back plate 3. After the two are matched with the help of mounting columns and mounting holes, the fastening holes of each other can be aligned with each other. At this time, screws are used as fasteners to fasten the two together to form a whole.

[0027] Specifically, the positioning function is achieved by the positioning structure formed between the positioning plate 203 and the convex edge 311; Figure 5-Figure 6 As shown, the circular protrusion 311 is formed with a plurality of arc-shaped teeth 331 on the side facing the positioning plate 203, and the edge of the positioning plate 203 is formed with three positioning protrusions 213 corresponding to the shape of the teeth 331. Since the positioning plate 203 is preferably made of plastic material as a whole, the positioning protrusions 213 can be positioned and matched with different teeth 331 through deformation when subjected to artificial twisting, so that the plug assembly 2 and the socket seat 1 are in a relatively fixed state after rotation.

[0028] Specifically, a through slot 223 is formed at the center of the positioning plate 203 , and a wire for connecting the plug pin 201 and the internal circuit components of the socket 1 passes through the through slot 223 .

[0029] Specifically, the plug assembly 2 may be any one of a US plug, a UK plug, a European plug or a Chinese plug, and its pin 201 is mounted on the rotating seat 202 .

[0030] As mentioned above, the expansion board of the existing design may not be installed and used due to the presence of foreign objects around the power socket; for example, the wall where the desk is usually placed in the room will have a power socket installed above the desk. If the distance between the power socket and the desk is too small, the expansion board will not be able to be plugged into the power socket because the bottom is blocked by the desk. When encountering such a situation, the design of this design can change the direction of the board socket by rotating the plug assembly, so that the expansion board can be normally plugged into the power socket for use. Compared with the traditional design, the expansion board of this design allows users to make independent adjustments according to different indoor environments, so it has higher environmental compatibility.

[0031] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
