Abstract

The utility model relates to a line drawing board, which is characterized in that extremely dense flanges are uniformly distributed on the surface of a board body, each flange is regularly and closely connected, the tips of all the flanges and the connected pits thereof form parallel linear arrangement, measuring scale scales are arranged on the periphery near the surface of the board body, and a criss-cross grid is arranged in the center of the board body to provide reference, so that a straight line can be drawn quickly without being skewed.

Description

Scribing plate

The utility model relates to a kind of line tool, particularly a kind of scribing plate.

Generally carry out the custom of free-hand setting-out or drafting form by people, in order to make the lines of drawing straight, be nothing but directly to utilize aids such as various ruler or angle square, as shown in Figure 1, utilize this ruler or angle square to have straight side, and make nib near and displacement gradually so that obtain the effectiveness of straight lines.

Yet though the traditional setting-out mode of this kind can obtain the effect of straight lines, but still the disadvantage that has inevitable shortcoming and use is analyzed as the back now one by one:

1. not really practical:

Tradition uses various straight (angle) chi when carrying out setting-out, only can draw single straight lines, and then can't reach easily for parallel lines, and must can reach by other auxiliary scale tool, be that practicality is not high; Secondly, about in the use,,, cause the situation that when removing, causes the paper spot unclean if the situation that this nib has is excessive, leakage of oil is black tends to be infected with on it because of nib must slide displacement near the side of straight (angle) chi.

2. poor durability:

Straight (angle) chi of tradition widespread usage reaches picture straight line purpose, its main cause is that its material is harder, when nib near the time be difficult for crooked, and the straight lines that can draw, but owing to may crack or breach occur because of human factor causes side after long-term use the, and then the straight lines that can't draw; And softer straight (angle) chi of another kind of material of using always on the market, though can improve above-mentioned shortcoming, but in the use, the user must directly (angle) chi be smooth stably on paper, straight lines can draw, therefore very inconvenience in the use, and this chi easily is heated or overbending and produce distortion, also can cause user's puzzlement in use in the future.

Because tradition is used the aid of chi, various shortcoming and disadvantage that it has when setting-out or drafting form, this creator is constantly studied improvement with great concentration, and has the utility model of this practicality to produce eventually, and thoroughly address the above problem, use for popular easy to use.

Main purpose of the present utility model is that a kind of scribing plate will be provided, and it can use for people are convenient, reaches according to this easily, setting-out fast or draw form and the use aid of need not arranging in pairs or groups.

Another purpose of the present utility model is that a kind of scribing plate will be provided, and it has suitable locating effect, uses and avoids in the setting-out process causing the crooked situation of lines because of improper slip.

For achieving the above object, the utility model provides a kind of scribing plate, it is characterized in that: mainly be to be formed with equally distributed superfine close flange in a plate body, and on plate body surface nearly periphery is provided with the gage scale, central authorities are provided with crisscross grid as reference, all flanges are closely to link to each other regularly simultaneously, and its depression most advanced and sophisticated and that be connected with another flange all forms arranged in a straight line, by this, when paper is layed on the plate body, must provide the guide function of nib when the setting-out by this depression, and the straight lines that can draw easily.

The utility model is simple in structure, sees through the depression guide function of setting-out plate body, does not need by other straight (angle) chi aid, just can be easily, setting-out fast or draw form; The design of this scribing plate bottom surface matsurface, can increase plate body put on the table frictional force and strong fix on desktop, the carrying out that helps setting-out or draw form.

Further specify the technical solution of the utility model and embodiment below in conjunction with accompanying drawing.

Description of drawings;

Fig. 1 is the enforcement view of known setting-out mode;

Fig. 2 is a planar structure front view of the present utility model;

Fig. 3 is a surface structure stereogram of the present utility model;

Fig. 4 is a partial structurtes schematic diagram of the present utility model;

Fig. 5 is a partial structurtes cutaway view of the present utility model;

Fig. 6 is an enforcement view of the present utility model;

Fig. 7 is a surface structure bottom view of the present utility model.

Shown in Fig. 2,3,4, structure of the present utility model, comprise a rectangular plate body 1 substantially, this plate body 1 is to be formed with even distribution and very fine and closely woven flange 10 on the surface, and is printed with gage scale 11 in nearly edge, and is provided with crisscross grid 12 in central authorities, use provide, user's benchmark or reference in use, and this flange 10 as shown in Figure 5, is to bring together towards most advanced and sophisticated 14 from the bottom, and slightly is pyramid modeling by what analyse and observe sight; Each flange 10 is regularly arranged and closely links to each other each other again, and the depression 15 of the tip 14 of all flanges 10 and connecting place thereof all forms parallel arranged in a straight line on the plate body 1; And must carrying out smoothly for operations such as free-hand setting-out of user or drafting forms by above structure.

According to said structure, when the utility model on reality is used, as shown in Figure 6, earlier plate body 1 is placed on the desktop, again the paper tiling is located on the plate body 1, so when operations such as setting-out or drafting form, can be earlier according to the grid 12 of being located at plate body 1 surperficial antermarginal scale 11 and central authorities, and the preliminary election decision position of desiring setting-out on paper, then as long as the application of force a little, just light direct required lines that on paper, draw by pen; Because nib is to slide against rule and equally distributed each flange 10 its depression that are connected to each other 15 on the plate body 1, therefore, sees through depression 15 guide functions of plate body 1, the lines that just can easily draw obtain straight effectiveness.

Secondly, if the user for fear above-mentioned in the setting-out process because of paper slides accidentally, and cause the lines that draw crooked, then can utilize general geometrical clamp commonly used to give the clamping location, just can prevent the displacement slip of paper by this effectively.

As shown in Figure 7, this case also can impose coarse processing and form the form with matsurface 13 in plate body 1 bottom surface, and by the design of this matsurface 13, can increase the friction that contacts with desktop when plate body 1 is seated in desktop, so so that firm in use being positioned on the desktop of plate body 1, help setting-out or draw the carrying out of operations such as form.

In sum, the bottleneck commonly used that the technological thought that the utility model constitutes is broken through, have outstanding advance and practicality, in fact can not be singly can get close examination with general scientific principle or experience, and through looking into correlation technique data and commercially available situation, all do not have and duplicate in the utility model, its novelty is indubitable especially, be to meet the regulation of Patent Law utility model fully, so file an application in accordance with the law.
