Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

as shown in fig. 1 to 7, the utility model provides a removable battery formula smoke detector, include: shell, circuit board and battery, the shell includes: the battery box comprises an upper cover 1, an intermediate box body 2, an offline limiting mechanism 3, an arched cover 4 and a lower cover 5, wherein the upper cover 1 covers the intermediate box body 2, a circuit board is installed between the upper cover 1 and the intermediate box body 2, the intermediate box body 2 is sunken towards one side of the upper cover 1 to form the arched cover 4, the bottom of the intermediate box body 2 is covered by the lower cover 5, the lower cover 5 and the arched cover 4 are matched to clamp a battery, an insertion hole 21 is formed in the intermediate box body 2, an insertion part 6 is formed in the lower cover 5, the insertion hole 21 is used for inserting the insertion part 6 in a direction parallel to the central line of the intermediate box body 2, the offline limiting mechanism 3 located beside the insertion hole 21 is installed on the intermediate box body 2, and the offline limiting mechanism 3 is used for limiting the insertion part 6 to be detached from the intermediate box body 2; the offline limiting mechanism 3 includes: the middle box body 2 is provided with a convex part 31 and a pressing arm 32, the side close to the upper cover 1 of the middle box body 2 is protruded to form the convex part 31, the convex part 31 is positioned beside the insertion hole 21, the pressing arm 32 is arranged on the arched cover 4, the pressing arm 32 is elastic, and the pressing arm 32 is matched with the middle box body 2 to limit the insertion part 6 to cross the convex part 31.

In order to ensure the strength of the pressing arm 32 and adjust the elastic performance of the pressing arm 32, a reinforcing rib 33 is installed on one side of the pressing arm 32 close to the upper cover 1. The reinforcing ribs 33 reinforce the thickness of the pressing arm 32, thereby increasing the strength of the pressing arm 32; the thickness of the reinforcing ribs 33 directly affects the elastic performance of the pressing arms 32, so that the elastic performance of the pressing arms 32 can be adjusted by adjusting the reinforcing ribs 33, and the requirement that a certain vertical beam is applied to rotate the lower cover 5 can be met, so that the insertion part 6 on the lower cover 5 can span the convex part 31, and the lower cover 5 can be detached.

In order to guide the rotation of the pressing arm 32, a rotation support leg 331 is formed at an end portion of the reinforcing rib 33 connected to the arch cover 4, and the rotation support leg 331 acts on the upper cover 1 to guide the rotation of the pressing arm 32. For convenience of production and guiding of rotation of the pressing arm 32, the upper cover 1 is designed to be tightly attached to the rotation supporting foot 331, and increase of production cost caused by guiding of rotation of the pressing arm 32 by means of an external component is avoided.
