Line chi

Technical field

This utility model relates to a kind of stationery, particularly relates to a kind of line chi.

Background technology

The subjects such as line chi also has person to be a chi, has accurate straight line seamed edge, is used for measuring length and mapping, is generally used for measuring shorter distance or drawing straight line, is widely used in mathematics, measures, engineering.Application number is a kind of line chi disclosed in the Chinese invention patent description of 201310347877.3, comprise line chi body, the outer end of the upper surface of described line chi body is provided with hypotenuse, described hypotenuse is carved with scale, in use, line chi is placed on paper, and scale is little to the distance of paper, when positioning on paper with pen, it is more accurate to position.But when using above-mentioned line chi setting-out, hands often exceeds line chi, the especially easy problem occurring that line drawing is uneven.

Utility model content

The shortcoming of prior art in view of the above, the technical problems to be solved in the utility model is in that to provide a kind of line chi, and described line chi solves the problem that setting-out is uneven.

For achieving the above object, this utility model provides a kind of line chi, and including body, the outer end of the upper surface of described body is provided with hypotenuse, and described hypotenuse is provided with scale；Described body is provided with slotted hole, and described slotted hole is provided with chute, and described line chi also includes a pointer, and described pointer coordinates with described slide, and the high order end in described slotted hole is provided with pen.

Preferably, described scale is protruding on described hypotenuse.

Preferably, described pointer includes connecting portion and L-shaped pointer body, and described pointer body is made up of limit anyhow and vertical edge, and described vertical edge points to described scale, and described limit anyhow is connected with described connecting portion, and described connecting portion coordinates with described slide.

Preferably, described chute is made up of two dovetail grooves, and described connecting portion is arranged to the dovetail shaped corresponding with described dovetail groove.

Preferably, the lower surface of described line chi is additionally provided with skid resistant course.

As it has been described above, the line chi that this utility model relates to, have the advantages that this utility model simple in construction, modern design, with low cost, by the body of online chi arranges elongated hole, and coordinate pointer, solve the problem that setting-out is uneven, and be accurately controlled the length of setting-out.

Detailed description of the invention

By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily.

Notice, the structure of this specification institute accompanying drawings depicted, ratio, size etc., all only in order to coordinate the disclosed content of description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the adjustment of the modification of any structure, the change of proportionate relationship or size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still drop on the disclosed technology contents of this utility model and obtain in the scope that can contain.Simultaneously, in this specification cited as " on ", D score, "left", "right", " centre " etc. term, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.

As depicted in figs. 1 and 2, this utility model provides a kind of line chi, and including body 1, the outer end of the upper surface of described body 1 is provided with hypotenuse 11, and described hypotenuse 11 is provided with scale 2；Described body 1 is provided with slotted hole 3, and the position that described body 1 is connected with described slotted hole 3 is provided with chute 12, and described line chi also includes a pointer 4, and described pointer 4 is slidably matched with described chute 12.When using this device; pen 6 is positioned at the high order end of described slotted hole 3; then setting-out to the right; described pointer 4 is promoted to move right; pointer 4 arrives and stops when specifying position; neat in order to ensure setting-out, the width of described slotted hole 3 lower surface is less than the width of upper surface, and the lower surface of described slotted hole 3 can hold nib traverse.

As in figure 2 it is shown, generally line chi adopts ink to be printed as scale, but be easily worn, therefore, this utility model can by described scale 2 projection on described hypotenuse 11, even if ink fades also can clearly represent scale.

As shown in Figure 1 to Figure 3, preferably, described pointer 4 includes connecting portion 41 and L-shaped pointer body 42, described pointer body 42 is made up of limit 421 anyhow and vertical edge 422, described vertical edge 422 points to described scale 2, and described limit anyhow 421 is connected with described connecting portion 41, and described connecting portion 41 is slidably matched with described chute 12, the pen core of described vertical edge 422 and described pen 6 is positioned on same axis, and reading is more accurate.

Preferably, described chute 12 is made up of two dovetail grooves, and described connecting portion 41 is arranged to the dovetail shaped corresponding with described dovetail groove, and during use, mobile described pointer 4 is more flexible light.

Preferably, the lower surface of described line chi is also fixed with skid resistant course 5, and when effectively preventing from using described line chi, the mobile situation causing setting-out uneven occurs in line chi, and described skid resistant course 5 can be moccasin layer.In order to further ensure the effect of setting-out, whole line chi is made of clear material.

In sum, this utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.

Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for restriction this utility model.Above-described embodiment all under spirit of the present utility model and category, can be modified or change by any those skilled in the art.Therefore, art has all equivalence modification or changes that usually intellectual completes under the spirit disclosed without departing from this utility model with technological thought such as, must be contained by claim of the present utility model.
