Mask box having a buckling structure

摘要

A mask box having a buckling structure includes a base, a cover and a plurality of buckling elements. The base is configured to support a mask and has a plurality of troughs. The cover covers the base and has a plurality of pivotal portions. The buckling elements are positioned to correspond to the troughs. Each buckling element includes an engaging block and an elastic arm connected to the pivotal portion. The engaging block moves away from the periphery of the cover when the engaging block is subjected to an external force. The engaging block is buckled into the trough via an elastic restoring force of the at least one elastic arm when the external force is removed. By this arrangement, the assembly of the buckling elements is simplified and its product cost is reduced. Further, the present invention conforms to the requirements for environmental protection.

主权项

1. A mask box having a buckling structure, including;
a base, configured to support a mask, a bottom edge of the base having a plurality of troughs; a cover, covering the base, an inner periphery of the cover having a plurality of pivotal portions; and a plurality of buckling elements, positioned to correspond to the troughs, each buckling element comprising an engaging block and at least one elastic arm extending from the engaging block, the other end of the at least one elastic arm being connected to one pivotal portion; wherein the engaging block moves away from the periphery of the cover when the engaging block is subjected to an external force, the engaging block is buckled into the trough via an elastic restoring force of the at least one elastic arm when the external force is removed, and wherein each pivotal portion is configured as a pivotal shaft, an end of the at least one elastic arm connected to the pivotal portion is configured as a sleeve, and the sleeve is put on the pivotal shaft and rotatable relative to the pivotal shaft.
