[0006] It is further configured as follows: a positioning step is provided on one side of the groove, and a limiting protrusion is provided on the other side.

[0007] It is further configured as follows: a limiting ring is provided on the outer wall of the end of the plug-in platform, and an inward limiting edge is provided on the inner edge of the decorative cover.

[0008] It is further configured as follows: an opening is provided on one side of the decorative cover, and a reinforcing rib extending inwardly is provided on the decorative cover at the inner side of the opening.

[0009] It is further configured as follows: an end cover is provided at the rear end of the hollow main body, two symmetrical extension pieces are provided on the side of the end cover, and an extension groove is provided at the rear end of the hollow main body.

[0010] It is further configured as follows: an end cover is provided at the rear end of the hollow body, two symmetrical through holes are provided on the side of the end cover, and a fixing hole corresponding to the through holes is provided on the side of the rear end of the hollow body.

[0011] In summary, the utility model has the following beneficial effects: the decorative cover can be doubly fixed by the limiting ring and the annular ring, so that when the decorative cover is detached, it can be found and installed back in time, avoiding the decorative cover from falling off and affecting the appearance and connection stability. At the same time, the rear end of the hollow body also double fixes the end cover, which can also ensure the stability of the structure inside the charging module. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0016] The USB mobile phone charging module comprises a hollow body 1, a ring sheet 2 is arranged on the side of the front end of the hollow body 1, a docking station 3 is arranged at the front end of the ring sheet 2, and a USB socket (i.e., a charging port, a power plug port and an indicator light) is arranged on the front of the docking station 3.

[0017] An annular ring 4 is arranged on the side of the docking station 3, and two clamping blocks 5 are symmetrically arranged on the annular ring 4. A circular decorative cover 6 is arranged on the docking station 3, and an inner edge 7 is arranged on the inner wall of the decorative cover 6, and a groove 8 corresponding to the clamping block 5 is arranged on the inner edge 7.

[0018] A limiting ring 11 is provided on the outer wall of the end of the plug-in platform 3, and an inward limiting edge 12 is provided on the inner edge 7 of the decorative cover 6. When the decorative cover 6 is installed, the limiting edge 12 can be first clamped on the limiting ring 11, and then the position is adjusted and continued to be pressed, so that the limiting edge 12 is clamped on the annular ring 4, and at the same time, the clamping block 5 is embedded in the groove 8. On the one hand, the decorative cover 6 is prevented from falling off by two layers of limiting (i.e., the limiting ring 11 and the annular ring 4), and on the other hand, the decorative cover 6 is prevented from rotating, thereby increasing the stability of the installation.

[0019] A positioning step 9 is provided on one side of the groove 8, and a limiting protrusion 10 is provided on the other side. The positioning step 9 can facilitate the alignment of the groove 8 and the block 5 when the decorative cover 6 rotates. The limiting protrusion 10 can abut against the block 5 to further prevent the decorative cover 6 from rotating.

[0020] An opening 13 is provided on one side of the decorative cover 6, and a reinforcing rib 14 extending toward the inner edge 7 is provided on the decorative cover 6 at the inner side of the opening 13. When the decorative cover 6 is covered, the decorative cover 6 can be opened by going deep into the opening 13, and the reinforcing rib 14 can increase the durability of this position and avoid damage.

[0021] An end cap 15 is provided at the rear end of the hollow body 1, and two extension pieces 16 are provided on the side of the end cap 15, and the extension pieces 16 are symmetrically arranged. An extension groove 17 is also provided on the side of the rear end of the hollow body 1, and the extension piece 16 corresponds to the extension groove 17. When the end cap 15 is installed, the extension piece 16 enters the extension groove 17, thereby achieving the fixation of the end cap 15. Further, a through hole 18 is provided on the end cap 15, and a fixing hole 19 is also provided at the rear end of the hollow body 1. A screw is inserted into the fixing hole 19, and the screw is inserted into the through hole 18 to further fix the end cap 15.

[0022] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
