Abstract

The utility model discloses a ruler. The utility model is shaped by squeezing with aluminum products. One side face of a ruler body is provided with an arc-shaped convex part, the arc-shaped convex part can be made into hollow, the ruler body is bunted on a plane by the arc-shaped convex part, and the edges of two side rulers are slightly away from the plane. The utility model is convenient to take and draw lines, and the ruler body is not easy to bend with the help of the arc-shaped convex part which is used as a rib.

Description

Chi

The utility model relates to a kind of chi, and You Zhiyi utilizes the ruler of aluminium extrusion forming.

The general at present ruler that uses probably has plastic cement system and metal (steel) to make two kinds according to the material differentiation, and the form of just using, plastic cement system chi mostly is and uses on the secretarial work, and the metallic chi then mostly is engineering, manufacturing industry is used; Again, the strength characteristics of the material of its limitation of the chi of above-mentioned two kinds of materials own, the maximum length of general plastic cement system chi (the preferable flexible soft plastic of tool) is probably made 30cm, and it is long promptly to have and scratches curved situation generation; Moreover when plastic cement system chi cooperated high tool of hardness or cutter line to use, damage was scraped by its datum quantity limit regular meeting, and can't mark straight line according to it when reusing; In addition, the metallic chi is scraped damage except that not subjecting to cutter, is widely used in outside the carpenter, its length more can increase many than plastic cement system chi, conveniently measures use, but because this type of metallic chi mostly is steel, its weight becomes to increasing with length, and for using frequent person, its carry-on portable is felt inconvenience very much; Again, these two kinds of chi tools, the design of its chi body is all supported the back side with the subsides of chi and work (tolerance) thing and is set as a plane, though right this kind form is beneficial to the smooth working substance of chi tool measures or rules, but cause also be difficult for behind the smooth working substance of chi tool vertical get from, and need mode with horizontal sliding promote the chi tool move apart the work object space do well out of to get from; Simultaneously, because of the chi tool smooth in working substance, when time spent with the capable line of general water liquid writing brush, its black liquid is can ooze to conflict intermarginal in working substance and chi body, hereat if just the chi tool is passed immediately, its black liquid promptly has to expand along the chi edge and dyes in the anxiety on working substance surface, and this causes the user need add time-consuming processing once the dirty China ink that increases on foot, and inconvenience is arranged more.

Supervise in above-mentioned that to commonly use the general disappearance of depositing of product unavoidable, the utility model purpose is promptly to provide that a kind of intensity is good, light weight and easy-to-use chi.

For reaching above-mentioned purpose, chi of the present utility model mainly is the ruler of adopting with the aluminium extrusion forming, a side moulding one arc protuberance of chi body, and this arc protuberance can be hollow.

After adopting said structure, the utility model chi body so arc protuberance form a rib support effect, and not flexible, intensity is good; The arc protuberance is a hollow, i.e. material-saving loss of weight again; Posting working substance when line in the chi body with the arc protuberance, is to push a side to paste and support working substance and use, and pressing force disappears, and the chi body is that fulcrum makes both sides chi edge slightly from working substance with the arc protuberance promptly, unlikelyly is infected with black liquid, also can make a side perk, conveniently get from, easy-to-use.

Below in conjunction with drawings and Examples the utility model is done and to be described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the view on not stressed placement of the present utility model one plane;

Fig. 3 is the enforcement illustration that the utility model line is used;

Fig. 4 be the utility model desire to get from the time the enforcement illustration.

As shown in Figure 1, chi of the present utility model is to be set as a ruler form, be to adopt with the aluminium extrusion forming, wherein: the wide plane of structure of the body of chi can be established tool one arc flexibility, and lie across in a side (back side) of chi body 1 central authorities and to form an arc protuberance (11), and arc protuberance (11) can be a ducted body, install on a plane with arc protuberance (11) when chi body (1) and be not subjected under any power effect, as shown in Figure 2, the both sides chi edge (12) of chi body (1) are to be the fulcrum balance with arc protuberance (11), and slightly from the plane.

Because above-mentioned design and equilibrium state, when being used in line work, as shown in Figure 3, be with hand by nose bar body (1) one side, make this side chi edge (12) conflict work (tolerance) thing, again the work that can do line or cut along chi edge (12); And take behind chi body (1) when the hand of pushing, this chi body (1) promptly recovers both sides chi edge (12) voluntarily slightly from the state on plane, and the writing brush China ink liquid that this form can be avoided ruling is infected with stained working substance surface because of the slippage of chi body (1).

In addition, when on desiring, fetching the chi tool by the working substance plane, with utilizing hand one to refer to other side chi edge (12) be stuck up from working substance by nose bar body (1) one side chi edge (12), this chi body (1) and working substance from the promptly convenient finger in space stretch put with the chi tool directly vertical get from, can take to moving apart working substance and need not to pass earlier chi tool level.

Again, chi body of the present utility model (1) is provided with this arc protuberance (11), also has both a rib support effect, make flat rectangular chi body (1) tool one ribs, if its length is grown also unexpected stressed bending again, and whole chi body (1) is that to adopt the aluminium of light weight made, not Shen Chong as the steel chi; Moreover arc protuberance (11) is set as hollow, material-saving not only, also weight reduction, in the use more smoothly.

Claims (2)

1, a kind of chi is to adopt aluminium to extrude one-body moldedly, it is characterized in that: the side central authorities of chi body form an arc protuberance.

2, chi as claimed in claim 1 is characterized in that: the arc protuberance is a ducted body.
