Description

Technical Field

[0001] The utility model relates to the technical field of abacus, in particular to a folding abacus. Background Art

[0002] Abacus, also known as abacus or counting beads, is a form of manually operated calculation aid. Before the emergence of Arabic numerals, abacus was a widely used calculation tool in the world. The structure of abacus generally includes four parts: frame, beam, gear, and beads. The frame is the border around the abacus, which plays a supporting and connecting role; the beam is the horizontal bar connected to the abacus frame, usually two bars, which divides the abacus into two parts: upper beads and lower beads; the gear is a thin rod that passes the counting beads. The upper set of the beam is called the upper gear, and the lower set of the beam is called the lower gear.

[0003] Abacus is widely used in life. The overall structure of the abacus is mostly an integrated structure, so it is fixed. However, since the volume and shape of the abacus cannot be changed, it takes up a large space when carried. For people who need to move or carry the abacus frequently, this undoubtedly increases the inconvenience. In addition, it takes up a certain storage space when stored, especially when space is limited, which may cause troubles in storage and organization. For this reason, a foldable abacus is proposed.

The upper frame stops moving, thereby realizing the contraction of the abacus as a whole from top to bottom. The overall volume of the abacus can be further reduced before folding, and the convenience is high. BRIEF DESCRIPTION OF THE DRAWINGS
