Abstract

The utility model belongs to a triangular ruler with compasses. The utility model is composed of a ruler, an edge ruler, a sliding ruler, a sliding block, a pencil core, a pencil core clamp, a positioning needle, a positioning needle clamp, and a connecting pin, wherein a sliding groove is arranged on the ruler, one end of the ruler is hinged with the edge ruler, the other end of the edge ruler is hinged with the sliding ruler, the other end of the sliding ruler is connected in the sliding groove arranged on the ruler, the sliding block which can be horizontally moved is also arranged in the sliding groove, and the positioning needle clamp used for gripping the positioning needle is arranged at one end where the ruler is connected with the edge ruler, during drawing, the distance between the pencil core and the positioning needle is determined through moving the sliding block, the triangular ruler can demonstrate through forming a right-angle triangular ruler, an equilateral triangular ruler, and the compasses during the operation process, thereby the purpose of drawing a straight line, a circle, or a semicircular curved line is realized, one tool is multi-purpose, and the carrying and the operation are convenient.

Description

The set square that has compasses

One, affiliated technical field

The utility model belongs to the drawing aid, particularly a kind of set square with compasses.Belong to operation Department of Transportation by International Patent Classification (IPC) (1PC) division, printing branch is write or drawing appliance; The big class of office appliance is write or drawing article; The assistant product group of writing or draw, other class drawing instrument not to be covered or write or big group of drawing appliance or annex the little technical group field of multiple writing device.Classification number is B43L 13/00.

Two, background technology

At present, drawing instruments such as existing set square, compasses various in style, but function is all comparatively single, the usefulness of generally can only draw, measuring, also modified drawing instruments such as some multipurpose set square, Napier's compasses, but complex structure is still arranged, use weak point such as inconvenience, this brings inconvenience to work such as the drawing of user in study, teaching, scientific research process, measurements.

Three, summary of the invention

The purpose of this utility model is to overcome the above-mentioned deficiency of prior art, a kind of set square that has compasses is provided, this has the set square of compasses, can compatible function of drawing straight line, circle or radius curve, can solve common set square and the single problem of compasses purposes, simple in structure, highly versatile.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of set square that has compasses, by ruler, the limit chi, slide rule, slide block, pen core, the pen core folder, pilot pin, the pilot pin folder, connecting pin is formed, it is characterized in that: on ruler, offer a chute, ruler one end and limit chi hinge, the limit chi other end and slide rule hinge, and the slide rule other end is connected among the chute of offering on the ruler, thereby form one respectively with ruler, limit chi and slide rule are the set square on three limits, because move left and right in the chute that an end of slide rule can be offered on ruler forms drawing square or equilateral triangle chi so can demonstrate.

In the such scheme, also be provided with a slide block in the chute of on ruler, offering, an end that is connected with the limit chi at ruler is provided with the pilot pin folder that is used for the clamping pilot pin, described slide block is provided with a pen core folder that is used for the clamping pen core, can horizontally slip in the chute that this slide block is offered on ruler, during drawing, can determine distance between pen core and the pilot pin by moving slider, promptly determine the picture radius of a circle, so that adapt to the needs when drawing with compasses.

In such scheme, described ruler is marked with the scale of measuring commonly used, and ruler can be used to draw straight line or measure Len req unit as the long limit of set square, also can directly measure radius and draw circle on ruler.Also can on limit chi and slide rule, marking measure as required, select so that have more measurement unit when drawing.

In the above scheme, described limit chi and slide rule equal in length.Connector at ruler and limit chi, limit chi and slide rule hinge place is a connecting pin.

In the such scheme, described pilot pin folder and slide block can rotate 90 degree.When drawing straight line, can pilot pin folder and moving 90 degree of slide block be placed and the ruler parallel position with the set square of band compasses.When the set square of band compasses is used as compasses draw circles or radius curve, can turn to pilot pin folder and slide block and the ruler upright position, make pilot pin and pen core become the bipod of compasses, thereby realize that the utility model can compatible purpose of drawing straight line, circle or radius curve.

The beneficial effects of the utility model are: because the utility model has adopted slide rule and slide block structure with respect to the ruler activity in technical scheme, form drawing square, equilateral triangle chi and compasses so in use can demonstrate, thereby realize the many usefulness of a tool, carry, easy to use.

Four, description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Schematic diagram when Fig. 1 is the utility model place set square state.

Schematic diagram when Fig. 2 is the utility model place compasses state.

Fig. 3 is the partial enlarged drawing of the utility model slide block structure.

In the drawings: 1. ruler, 2. chute, 3. scale, 4. slide block, 5. pen core, 6. pilot pin, 7. pilot pin folder, 8. connecting pin, 9. limit chi, 10. slide rule, 11. pen cores folder.

Five, the specific embodiment

A kind of set square that has compasses, by ruler 1, limit chi 9, slide rule 10, slide block 4, pen core 5, pen core folder 11, pilot pin 6, pilot pin folder 7, connecting pin 8 is formed, it is characterized in that: on ruler 1, offer a chute 2, ruler 1 one ends and limit chi 9 hinges, limit chi 9 other ends and slide rule 10 hinges, and slide rule 10 other ends are connected among the chute of offering on the ruler 12, thereby form one respectively with ruler 1, limit chi 9 and slide rule 10 are the set square on three limits, because move left and right in the chute 2 that an end of slide rule 10 can be offered on ruler 1 forms drawing square or equilateral triangle chi so can demonstrate.

In the such scheme, also be provided with a slide block 4 in the chute of on ruler 1, offering 2, an end that is connected with limit chi 9 at ruler 1 is provided with the pilot pin folder 7 that is used for clamping pilot pin 6, described slide block 4 is provided with a pen core folder 11 that is used for clamping pen core 5, can horizontally slip in the chute 2 that this slide block 4 is offered on ruler 1, during drawing, the distance that can determine between pen core 5 and the pilot pin 6 by moving slider 4, promptly determine the picture radius of a circle, so that adapt to the needs when drawing with compasses.

In such scheme, described ruler 1 is marked with the scale of measuring commonly used, and ruler 1 can be used to draw straight line or measure Len req unit as the long limit of set square, also can directly measure radius and draw circle on ruler 1.Also can on limit chi 9 and slide rule 10, marking measure as required, select so that have more measurement unit when drawing.

In the above scheme, described limit chi 9 and slide rule 10 equal in length.Is connecting pin 8 with limit chi 9, limit chi 9 with the connector at slide rule 10 hinge places at ruler 1.

In the such scheme, described pilot pin folder 7 and slide block 4 can rotate 90 degree.When drawing straight line with the set square of band compasses, can press from both sides 7 and slide block 4 moving 90 degree to pilot pin, place and ruler 1 parallel position.When the set square of band compasses is used as compasses draw circles or radius curve, can pilot pin press from both sides 7 and slide block 4 turn to and ruler 1 upright position, make pilot pin 6 and pen core 5 become the bipod of compasses, thereby realize that the utility model can compatible purpose of drawing straight line, circle or radius curve.
