Abstract

A locking assembly for locking a first frame to a second frame, comprising a shell, a sliding component, a locking block and a transmission. The shell for connecting to the first frame. The sliding component slidably connected to the shell, and a guiding slot is defined on the sliding component. The locking block rotatably connected to the shell, a clamping notch is defined on the locking block and exposed from a top side of the shell for clamping a locking member on the second frame. The transmission group is connected to the sliding component by the guiding slot, the transmission group is further connected to the locking block. The transmission group is configured to rotate the locking block to clamp or unclamp the locking member, when the sliding component slides along a first direction to guide the transmission group by the guiding slot.

First claim
