Refer to FIG. 8 and FIG. 9, which are cross-sectional views of a locking cover module of the waterproof accommodating container for a battery of the present disclosure. In this embodiment, the battery-accommodating waterproof container 100 has multiple measures of waterproofing designs. First, for the first opening 11 at the bottom of the housing 10, the base-sealing element 24 of the transmission seat 20 can block moisture from entering into the housing 10. For the second opening 12 at the top end of the housing 10, firstly, the locking cover module 30 is covered on the second opening 12. If liquid accidently flows into the second opening 12, it still has multiple measures of waterproofing and absorbance. The first measure is that, the second sealing-element 433 is contacted against an inner surface of the housing 10 for blocking liquid. The second measure is that, the first absorbent element 434 fully surrounds the periphery of the battery-holding seat 40 for absorbing liquid. The third measure is that, the first sealing-element 431 is used to block liquid. Even if liquid is flowed to the receiving portion 41, a top end of the receiving portion 41 further provides the second absorbent element 432.
Refer to FIG. 8, which shows the battery-holding seat 40 is assembled in the housing 10, the elastic transmit-element 423 is compressed and an elastic force is accumulated. As shown in FIG. 9, if want to unlock the locking cover module 30 relative to the housing 10, an external force F is continuously exerted to the pressing unit P, and the latching bolts 32a, 32b move inward along the oblique rod 332 away from the wedging holes 14 of housing 10. In the meanwhile, an elastic force is exerted by the elastic transmit-elements 423 to push the battery-holding seat 40 away from the housing 10, so that a user can take out the battery-holding seat 40. The locking cover module 30 and the battery-holding seat 40 are ejected out of the housing 10 at the same time, so as to avoid losing the locking cover module 30 accidently.
Refer to FIG. 8, which shows the condition of the external force F is released from the button-module 35. In the meanwhile, the elastic element 36 provides the button-module 35 a restoring force for pushing the oblique rod 332 upward, and the latching bolts 32a, 32b are moved outward along the oblique rod 332 to engage into the wedging holes 14 of the housing 10. The waterproof accommodating structure 100 is restored to a locking condition. The locking process of the present disclosure is effortless. Since the housing 10 has the oblique portion 13, the latching bolts 32a, 32b can slide downward along an inner slanted surface of the oblique portion 13 until entering into the wedging holes 14. During the locking process, it is effort-saving, and it does not need to press the pressing unit P continuously.
