[utility model content]

Inconvenience when changeing and commonly use the inconvenience that box tool panel changes assembly operation in view of the battery of general battery case tool, the purpose of this utility model is to provide a kind of battery to extract the closure apparatus of box, makes panel and box body can firmly make up, use safely and be convenient to disassembly and assembly.

The closure apparatus that the utility model provides a kind of battery to extract box, this battery extract box and include a box body that is mutually combined by upper and lower cover, and are located at the panel of box body one end; It is characterized in that: on the two relative edge's faces of box body bottom, wait to be arranged with several and to protrude L-shaped rail mounted snap-latch piece, and the middle section, bottom, then be provided with the locating piece of protrusion; On panel dual-side face, be provided with the location lug that inwardly protrudes out in addition with respect to the snap-latch piece position, panel then is provided with the jamming seat of being made up of the flexure strip of space with respect to the locating piece place, this snap-latch piece engages this this locating piece of jamming seat clamping mutually with the location lug.

Described battery extracts the closure apparatus of box, and it is characterized in that: this locating piece can be set as positive taper or triangle.

Described battery extracts the closure apparatus of box, and it is characterized in that: locating piece and jamming seat can be set as one or more.

Described battery extracts the closure apparatus of box, it is characterized in that: the two relative flexure strip bottoms of this jamming seat, can bend inwards forms a bell shape that falls, and locating piece overhead kick clamping is located.

Battery of the present utility model extracts the closure apparatus of box, make panel and box body can firmly make up, use safely and be convenient to disassembly and assembly, can effectively overcome aforementionedly when commonly using battery and extracting box and only fasten the panel assembling by flange, institute may produce many disappearances that steadiness is not enough and dismounting is difficult.
