Description

Set square

Technical field

The utility model belongs to stationery or realia field, and in particular to a kind of set square.

Background technique

Existing set square is typically all the fixed right angle triangle of configuration or isoceles triangle plate etc., and in teaching classroom On, teacher is frequently necessary to draw triangle of various shapes, use it is very inconvenient, in addition, existing set square function compared with To be single, purposes is not extensive.

Utility model content

The problem of fixing and have a single function purpose of the utility model is to solve existing triangle panel configuration, and provide A kind of set square.

The utility model provides a kind of set square, described including set square ontology and the slide rule connecting with set square ontology Set square ontology be right angle triangles that both ends are 30 degree and 60 degree angles, the one end at 30 degree of angles is equipped with anti-slippery fellow, institute First sliding groove is equipped with inside three side ruler bodies of the set square ontology stated, first sliding groove is equipped with sliding slot mouth, is equipped in first sliding groove Two sliding blocks, the sliding block connecting screw, screw rod are external by sliding slot mouth stretching set square sheet；

It is equipped with second sliding slot inside the ruler body of the slide rule, screw rod is connect with second sliding slot, and slide rule passes through screw rod and three The connection of gusset ontology；

The slide rule is equipped with written end close to the one end at 30 degree of angles of set square ontology, inserts in written end equipped with chalk Hole.

Preferably, the anti-slippery fellow is made of rubber material.

Preferably, graduation mark is equipped on the interior outside of the set square body outer surface.

Preferably, the screw rod is equipped with nut far from one end of sliding block.

Preferably, the PVC material that the set square ontology and slide rule are all made of addition fluorescent powder is made.

The beneficial effects of the utility model

The utility model provides a kind of set square, and by the slide rule and sliding block of setting, adjustable slide rule is in first sliding groove Interior movement moves it any position on three sides, arbitrarily adjusts the angle, draws the triangle of different shape angle, when When not needing special shape, two sliding blocks can be located on one of side of set square ontology, make slide rule and set square sheet The coincidence on one side of body, when conventional set square uses；Meanwhile set square of the invention by slide rule one end be arranged written end and The one end at 30 degree of angles is equipped with anti-slippery fellow, can use when compasses, vdiverse in function, practical.

Specific embodiment

The utility model provides a kind of set square, as shown in Figure 1-3, include set square ontology 1 and connect with set square ontology 1 The PVC material that the slide rule 5 connect, the set square ontology 1 and slide rule 5 are all made of addition fluorescent powder is made, and can be improved in this way The brightness of whole set square.Graduation mark 4 is equipped on the interior outside of 1 outer surface of set square ontology.The set square Ontology 1 is the right angle triangles that both ends are 30 degree and 60 degree angles, and the one end at 30 degree of angles is equipped with anti-slippery fellow 2, and described is anti- Slippery fellow 2 is made of rubber material.First sliding groove 9, first sliding groove 9 are equipped with inside three side ruler bodies of the set square ontology 1 For closed form, first sliding groove 9 is equipped with sliding slot mouth 3, sets that there are two sliding block 10,10 connecting screws of sliding block in first sliding groove 11, screw rod 11 is stretched out outside set square ontology 1 by sliding slot mouth 3；Screw rod 11 is equipped with nut 7. far from one end of sliding block 10

It is equipped with second sliding slot 6 inside the ruler body of the slide rule 5, screw rod 11 is connect with second sliding slot 6, logical by screw rod 11 Crossing connect slide rule 5 with set square ontology 1 across second sliding slot 6；

As shown in Figures 4 and 5, the slide rule 5 is equipped with written end 8, nib close to the one end at 30 degree of angles of set square ontology 1 Chalk jack 12 is equipped in end 8.

Set square described in present embodiment when in use, when needing to draw triangle of different shapes, loose nut 7, sliding block 10 can slide, and after adjusting slide rule 5 is moved into any position, tightens nut 7, make slide rule 5 and set square ontology 1 It is relatively fixed, when drawing required triangle, but needing conventional set square, it is only necessary to which two sliding blocks 10 are slided into set square Ontology 1 wherein on one side on, make the overlapping on one side of slide rule 5 and set square ontology 1.

When needing picture bowlder, loose nut 7, sliding block 10 can be slided, and adjusted slide rule 5, be inserted into powder in chalk jack 12 Pen makes the radius of written end 8 circle at a distance from anti-slippery fellow 2, tightens nut 7, keep slide rule 5 and set square ontology 1 relatively fixed, It is the center of circle with anti-slippery fellow 2, rotary triangle plate allows chalk to do circumference telemechanical, circle required for drawing.
