Abstract
The utility model relates to an abacus, particularly an abacus of metal frame material. The abacus adopts hollow metal frame material, so that the size of the frame material can be larger and the intensity of the frame material can be increased given that the amount of the used metal material is not large. The frame material does not appear thin, and has light weight. Therefore, the utility model has the characteristics of good intensity, light weight and beautiful appearance.
Description
The utility model relates to a kind of abacus, relates in particular to the abacus of metal frame material.
The abacus of existing employing metal frame material, its frame material is solid, consider cost factor and economical with materials, the frame material can not design too much, and this abacus looks that the frame material is less, thinner, and is attractive in appearance inadequately, generous, and because the frame material is little makes that abacus intensity is relatively poor, because the frame material is solid,, increase the weight of users' such as students in middle and primary schools burden in addition though the abacus of more tiny formation is still relatively heavier.
The purpose of this utility model provide a kind of intensity better, the metal frame material abacus of light, the good looking appearance of weight.
To achieve these goals, technical solution of the present utility model is such: a kind of abacus, adopt the metal frame material, and wherein the frame material of abacus is a hollow-core construction.
Because in the above-mentioned technical solution, abacus adopts hollow metal frame material, make the size of frame material under few prerequisite, to make greatly of metal material, the also raising greatly of frame material intensity, and this frame material is not from seeming too thin in appearance, weight is lighter simultaneously, so this abacus has, and intensity is good, in light weight, the characteristics of good looking appearance.
Below in conjunction with drawings and Examples the utility model is described in further detail:
Fig. 1 is the cross-sectional view of a kind of metal frame material provided by the utility model.
Fig. 2 is the cross-sectional view of second kind of metal frame material provided by the utility model.
Fig. 3 is the cross-sectional view of the third metal frame material provided by the utility model.
Wherein: 1, end face; 2, side.
As Fig. 1, Fig. 2, shown in Figure 3, for the frame material of abacus adopts the frame material cross-sectional view of hollow-core construction, improving the resulting abacus in back on the one hand can economical with materials, has intensity height, in light weight, advantage that outward appearance is beautiful simultaneously.
Abacus frame material transversal section shown in Figure 1 is " mouth " font, and the end face 1 of frame material is one section circular arc camber.
Abacus frame material shown in Figure 2 is on the basis of abacus frame material shown in Figure 1 an one side 2 to be omitted middle one section, and the transversal section that makes the frame material is near " C " font.
Frame material transversal section shown in Figure 3 is " day " font, and the end face 1 of frame material is one section circular arc camber.
Claims (4)
1, a kind of abacus adopts the metal frame material, and it is characterized in that: the frame material of abacus is a hollow-core construction.
2, abacus according to claim 1 is characterized in that: frame material transversal section is " mouth " font, and the end face of frame material (1) is one section circular arc camber.
