Fig. 1 to 3 show an embodiment of the mobile power supply of the present application, and as with the conventional mobile power supply, the mobile power supply also mainly includes a power supply housing and a battery 1 accommodated in the power supply housing.

Referring to fig. 2, the key improvement of this embodiment is: the power supply case is composed of a case 2 having an open top and a case cover 3 having an open bottom. The outer surface of the housing 2 is formed with a ring-shaped outer bearing surface 201 that horizontally surrounds and a locking groove 202 above the outer bearing surface. The inner surface of the housing cover 3 is formed with a ring-shaped inner bearing surface 301 which is horizontally surrounded and a latch 302 which is located above the ring-shaped inner bearing surface. The housing cover 3 is sleeved outside the housing 2, and the latch 302 is embedded in the slot 202, so that the housing cover 3 and the housing 2 are fixed to each other by the cooperation of the latch 302 and the slot 202. An upper seal ring 4 is interposed between the top surface of the housing 2 and the annular inner bearing surface 301, and a lower seal ring 5 is interposed between the bottom surface of the housing cover 3 and the annular outer bearing surface 201.

The latch 302, the annular inner bearing surface 301 and the housing cover 3 are of an integral injection molding structure, and the slot 202, the annular outer bearing surface 201 and the housing 2 are of an integral injection molding structure. Thus, the latch 302 has a certain plastic deformation capability, when the shell cover and the shell are assembled, the shell cover can be pressed down by force, and the latch is plastically deformed under the action of external force and clamped into the clamping groove; if the interior of the power supply needs to be overhauled, the shell cover is pulled upwards with force, and the clamping tongue is plastically deformed under the action of external force and is separated from the clamping groove.

In order to better fix the position of the upper sealing ring 4, the present embodiment has a lower ring groove recessed downward on the top surface of the housing 2, and an upper ring groove recessed upward on the annular inner supporting surface 301, into which the upper sealing ring 4 is inserted.

As shown in fig. 2, the outer surface of the housing 2 above the annular outer bearing surface 201 is a vertical outer surface, and the aforementioned locking groove 202 is provided on the vertical outer surface. The inner surface of the cover 3 below the annular inner support surface 301 is a vertical inner surface on which the aforementioned latch 302 is provided.

The lower sealing ring 5 is a rubber pad coated with an adhesive to further improve the sealing property between the bottom surface of the shell cover and the annular outer bearing surface.

For convenient assembly, the openings of the housing 2 and the housing cover 3 are rectangular openings in the present embodiment, and the annular outer bearing surface 201 and the annular inner bearing surface 301 are rectangular ring structures.

The above embodiments are only for illustrating the technical concepts and features of the present application, and the purpose of the embodiments is to enable people to understand the content of the present application and implement the present application, and not to limit the protection scope of the present application. All equivalent changes and modifications made according to the spirit of the main technical scheme of the application are covered in the protection scope of the application.
