Self-locking quick disassembling charging device, battery cart device and mobile scanning terminal

The invention discloses a self-locking quick disassembling charging device used for a mobile scanning terminal. The self-locking quick disassembling charging device comprises a battery inner cart with a storage battery for charging the mobile scanning terminal, a charging plug installed on a front panel of the battery inner cart and used for being in butt joint with a socket of the mobile scanning terminal, and a butt-joint self-locking structure installed on the front panel of the battery inner cart and used for driving the charging plug to be in butt joint with the socket and locking the battery inner cart onto an inner rail rest unit when the charging plug and the socket are in butt joint. The self-locking quick disassembling charging device can lock the battery inner cart onto the inner rail rest unit, the situation of outage caused by disengagement of the charging plug and the socket in the power supply process can be prevented, it is ensured that the mobile scanning terminal can scan and process a large quantity of electronic seal packaging bags, and the working efficiency of scanning processing is improved. The invention further provides a battery cart device used for transferring the self-locking quick disassembling charging device and the mobile scanning terminal with the self-locking quick disassembling charging device.
