Abstract
The present invention provides a box latch. The box latch is provided with two wedge-shaped pins symmetrically arranged around its center, and the two wedge-shaped pins are movable into a wedge-shaped notch formed by mating parts of two spliced adjacent boxes and mating with the wedge-shaped pin to lock the two adjacent boxes. The two wedge-shaped pins are symmetrically arranged around its center such that only one box latch is required to lock two adjacent boxes together, reducing the number of splicing steps and box latches, further saving manpower and material resources. In addition, the wedge-shaped pin and the wedge-shaped notch are shaped and configured to mate with each other such that self-locking occurs when they are locked, thus providing a stable connection of the boxes.
