Abstract
The utility model provides a collapsible abacus, form including frame, crossbeam, pearl pole and bead, the frame is including the left side frame and the right frame, and the crossbeam includes and left crossbeam and right crossbeam all are provided with the skid resistant course on frame and the crossbeam face, and fixedly connected with crossbeam in the frame, pearl pole pass the crossbeam, goes up the lower extreme and fixes at the frame inboardly, and frame and the right frame all are equipped with through hinged joint between left crossbeam and the right crossbeam and fold paper on the left, and the cross -section of pearl pole is crossly, and the bead middle part is offered one and is cross perforation. The utility model discloses can enough reduce the noise of bead collision production mutually in the time of the operation, the design of pearl pole also can avoid controlling of bead to roll, can also realize the folding of abacus, simple structure, convenient to use.
Description
Technical field
The utility model relates to a kind of operational tool, is specifically related to a kind of Foldable counting frame.
Background technology
Abacus, as the simple computational tool of one of ancient Han people's innovation and creation, has been employed several thousand always.Even if can also play an important role in the society that nowadays computing machine is quite popularized.
The housing of the structure of abacus, crossbeam, pearl bar and bead composition, wait mutual collision between bead in use and easily produce noise, and when computing because traditional pearl bar is cylindric, bead easily left and right rolls, and due to the volume of abacus comparatively large, be inconvenient to for the user carry.
Summary of the invention
(1) technical matters solved
For the deficiencies in the prior art, the utility model provides a kind of Foldable counting frame, can either reduce bead collide with each other when computing produce noise, the pearl bar simultaneously redesigned also can avoid the left and right of bead to roll, can also realize abacus fold.
(2) technical scheme
For realizing above object, the utility model is achieved by the following technical programs:
A kind of Foldable counting frame, comprise housing, crossbeam, pearl bar and bead composition, housing comprises left frame and left frame, and crossbeam comprises left crossbeam and right crossbeam, it is characterized in that, described housing and crossbeam face are provided with skid resistant course, housing internal fixtion is connected with crossbeam, and described pearl bar is through crossbeam, and upper and lower side is fixed on inside housing, the cross section of pearl bar is cross, and it is cross perforation that described bead middle part offers a shape.
Further, described bead two sides is provided with magnetic sheet, and is provided with skid resistant course again on magnetic sheet.
Further, described skid resistant course is wear-resisting latex.
(3) beneficial effect
The utility model provides a kind of Foldable counting frame, and in the middle part of housing and crossbeam, the folding be provided with is connected through the hinge, and can be folded by abacus as required, be convenient for carrying.The design of pearl bar simultaneously, cross section is cross, structure, with crossly matching of boring a hole in the middle of bead, make bead that the shaking phenomenon of left and right not easily occur when computing, the two sides of bead is more provided with magnetic sheet, makes bead convenient mobile when computing, and the wear-resisting emulsion skidproof layer that magnetic sheet outside surface is also provided with is more effective to prevent from eliminating when abacus computing phase mutual friction between bead and the noise that produces.
Be provided with wear-resisting emulsion skidproof layer at the housing of abacus and beam outer surface, make abacus can be anti-skidding at smooth desktop.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.

Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, in the present embodiment, a kind of Foldable counting frame, comprise housing 1, crossbeam 2, pearl bar 3 and bead 4 form, housing 1 comprises left frame 101 and left frame 102, crossbeam comprises left crossbeam 201 and right crossbeam 202, housing 1 and 2, crossbeam are provided with skid resistant course 6, can easily slide when placing on the table by effectively preventing abacus, housing 1 internal fixtion is connected with crossbeam 2, pearl bar 3 is through crossbeam 2, upper and lower side is fixed on inside housing 1, be connected through the hinge between on the left side frame 101 and left frame 102 and be provided with a folding 8, same being connected through the hinge between left crossbeam 201 and right crossbeam 202 is provided with a folding 8, the convenient folding effect used can be played, the cross section of pearl bar 3 is cross, bead 4 middle part offers one for cross perforation 7, bead 4 two sides is provided with magnetic sheet 5, the more effective bead 4 that makes of magnetic sheet 5 energy is when computing, conveniently moving is quick, magnetic sheet 5 is provided with wear-resisting emulsion skidproof layer 6 again, wear-resisting emulsion skidproof layer 6 also can be eliminated bead 4 and produce unnecessary noise when computing.
Above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
