Abstract
The utility model relates to an abacus, particular is a two-use simulative abacus using for child. The structure includes a full-face frame, a beam connecting to the frame, a plurality of shelves with two ends extending into the frame respectively passing through the beam, abacus beads are stringed on the shelves, the frame in the back and the frame in the front of the abacus are injected moulding with forming in one piece by moulds, the beam connecting to the frame is provided in the frame in the back, a plurality of shelves respectively pass through the beam in the back with two ends extending into the frame in the back. The utility model combines the abacus face (front face) with the simulation face (back face) on the same one abacus, which is more convenient for use, the simulation face uses triaxiality solid structure with good hand feeling when using simulative abacus.
Description
Technical field
The utility model relates to a kind of abacus, is specially the dual-purpose analog abacus that a kind of child of being suitable for uses.
Background technology
Traditional abacus is made up of frame all around, middle beam and the shelves that are connected with frame, beam and the pearl of string on shelves.Utilize the computing method of abacus to be called rechoning by the abacus, the process of rechoning by the abacus can be dragged on to go and be calculated by the reality of bead, also can carry out mental arithmetic by imitative dialling (empty group).Now imitative dial to be to use a kind ofly have only frame, beam and do not have the special-purpose abacus of mental arithmetic of pearl, real dialling with imitative dialling do not carried out on same abacus, makes troubles to use.In addition, also having a kind of scheme that reality is dialled and imitate to dial carries out on same abacus, but real dial and the back side imitative dial be glue admittedly together, it is not firm to connect, and imitative the dialling at the back side is drawn in or is imprinted on real dialling on the plate, the visual effect that had not both had 3 D stereo does not have any feel during empty dialling yet, and is not suitable for very much child's use.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of existing abacus mental calculation abacus, provides that a kind of child of being suitable for uses, not only can dial but also can imitate the dual-purpose analog abacus of dialling in fact.
The technical solution of the utility model is as follows: a kind of dual-purpose analog abacus, comprise positive frame, the beam that is connected with frame, some pass respectively beam and two ends stretch in the frame grade, string has bead on the shelves, the frame at the abacus back side passes through the mold injection one-shot forming with the frame in front, be provided with the beam that is connected with frame in the frame at the back side, some shelves pass respectively in the beam at the back side and the frame that the back side is stretched at two ends.
Aforesaid dual-purpose analog abacus wherein, keeps the distance of 0.4～0.6cm between the plane, beam place at the abacus back side and the plane, frame place.
Aforesaid dual-purpose analog abacus wherein, all is embedded with a white wire on the beam at the abacus front and the back side.
The utility model is combined in rechoning by the abacus face (front) and falseface (back side) on the same abacus, uses more convenient.Falseface (back side) adopts 3-D solid structure, and certain feel is arranged when allowing simulation calculate.On the beam of rechoning by the abacus face (front) and falseface (back side) all embedding a white wire, can be better distinguish a position and ten bit lines with vision, its global design is more suitable for the child and uses.

Fig. 2 is falseface (back side) structural representation of dual-purpose analog abacus.
1. grades (front) 2. 3. 6. beam (back side) of bead 4. frames 5. grades (back side) of beam (front) among the figure
Embodiment
As shown in the figure, dual-purpose analog abacus comprises that the frame 4 by mold injection molding, the beam 2 that is connected with frame 4, some pass beam 2 and two ends respectively and stretch into shelves 1 in the frame 4, and string has bead 3 on the shelves 1, and above structure constitutes the rechoning by the abacus face of abacus.The frame at the abacus back side is a single injection-molded with positive frame, is provided with the beam 6 that is connected with frame 4 in the frame 4 at the back side, and some shelves 5 pass respectively in the beam 6 at the back side and the frame 4 that the back side is stretched at two ends, thus the falseface of formation abacus.The distance that keeps 0.4～0.6cm between the plane, beam place of abacus falseface and the plane, frame place forms 3-D solid structure, when allowing simulation calculate certain feel is arranged, and present embodiment is specifically chosen 0.5cm.Simultaneously, on the beam of rechoning by the abacus face and falseface all embedding a white wire, can be better distinguish a position and ten bit lines with vision, its global design is directly perceived, lively, is more suitable for the child and uses.String has 5 beads on each shelves 1 of abacus rechoning by the abacus face, and 1 is located at beam 2 tops, other 4 belows that are located at beam 2.
Claims (4)
1. dual-purpose analog abacus, comprise that positive frame (4), the beam (2) that is connected with frame (4), some pass beam (2) and two ends respectively and stretch into grade (1) in the frame (4), shelves (1) are gone up string bead (3), it is characterized in that: the frame at the abacus back side passes through the mold injection one-shot forming with the frame in front, be provided with the beam (6) that is connected with frame (4) in the frame at the back side (4), some shelves (5) pass respectively in the beam (6) at the back side and the frame (4) that the back side is stretched at two ends.
2. dual-purpose analog abacus as claimed in claim 1 is characterized in that: the distance that keeps 0.4～0.6cm between the beam at the abacus back side (6) plane, place and frame (4) plane, place.
3. dual-purpose analog abacus as claimed in claim 1 or 2 is characterized in that: all be embedded with a white wire on the beam at the abacus front and the back side.
4. dual-purpose analog abacus as claimed in claim 3 is characterized in that: each shelves (1) in abacus front are gone up string 5 beads (3), and 1 is located at beam top, other 4 belows that are located at beam.
