- a front cover, comprising:
- Alternatively, a waterproof groove can be provided in the surrounding edges of the frame, and the waterproof strip corresponding to the waterproof groove is disposed in the interior walls of the two sides' edges of the back cover and the interior wall of the blind end of the back cover.
- Moreover, the waterproof strip and the groove can be swapped from one another, i.e. the waterproof strip can be provided at the edges of the frame, and the waterproof groove corresponding to the waterproof strip can be disposed in the interior walls of two sides' edges of the back cover and the interior wall of the blind end of the back cover.
- According to an embodiment of the present invention, the waterproof case further comprises an outer locking shell to improve the waterproof performance, wherein the outer locking shell encases the assembly formed by the front cover and the back cover, and makes the two covers tight enough in order to achieve better waterproof performance.
- For better tight connection between the outer locking shell and the back cover, the present invention can be accomplished by two following concepts:
- First concept, the outer locking shell further comprises two lateral sides, each of which has a positioning slot for fixing the outer locking shell and the back cover; while a positioning bulge is disposed on each outer side wall of the back cover. When fixing the outer locking shell to the back cover, the positioning bulge will be inserted into the positioning slot of the outer locking shell for tight connection between the outer locking shell and the back cover. Further the positioning slot of the outer locking shell is likely a long narrow slot, and the positioning bulge of the back cover is also long narrow bulge.
- Second concept, the outer locking shell further comprises two lateral sides, each of which has a positioning bulge for fixing the outer locking shell and the back cover; while a positioning slot is disposed on each outer side wall of the back cover. When fixing the outer locking shell to the back cover, the positioning bulge will be inserted into the positioning slot for tight connection between the outer locking shell and the back cover. Further the positioning bulge of the outer locking shell is likely a long narrow track, and the positioning slot of the back cover is also long narrow-shaped.
- According to an embodiment of the present invention, the outer locking shell has an opening corresponding to the charger port or the headphone jack of the electronic device in order to use the electronic device conveniently upon placing the outer locking shell.
- According to an embodiment of the present invention, in order to improve the close fit between the open end of the back cover and the bottom wrap of the front cover, the open end of the back cover is provided with multi-step grooves, and the bottom wrap of the front cover is also provided with multi-step raised platforms corresponding to the multi-step grooves. The multi-step grooves will be joined to the multi-step raised platforms hermetically and the case can be sealed when in use. According to an embodiment of the present invention, the waterproof case can be designed in the following two ways, so that the first opening can be sealed.
- As first way, the first sealing plug is of L shape which consists of a horizontal plane member and a vertical member. A locking bulge is disposed on the inner wall of the horizontal plane member to snap the back side of the bottom wrap. The vertical member is of arc-shape corresponding to the curve side of the bottom wrap. A one-piece gasket is disposed on the inner wall of the vertical member to plug the first opening. Moreover, skid-proof strips can be disposed on the outer side of the vertical member in order to operate the L-shaped plug conveniently.
- As second way, a square slot is provided around the first opening, and the first opening is within the square slot. The first sealing plug is embedded in the square slot and can be slid within the slot to seal the first opening. Moreover, skidproof strips are provided on the outer surface of the plug in order to make it easy to slide the plug in.
