Description

A kind of angle square

Technical field

This utility model relates to a kind of stationery, is specifically related to a kind of angle square.

Background technology

In present teaching process, commonly use protractor and ruler is drawn angle or draws arc, traditional stationery can only be used alone, such as protractor angle measurement, ruler setting-out section, compasses draw circle or arc, and multiple stationery need to pick and place back and forth the class period of waste student, and multiple stationery uses needs to reorientate back and forth, mapping data error will definitely do not caused in location.

Number of patent application 201420386616.2 relates to a kind of angle square, including the blade plate that line drawing ruler and thickness of slab are vertically extending, blade plate offers the angulation hole running through blade plate upper and lower side, described angulation hole is a shoulder hole, angulation hole has macropore section setting up and down and aperture section, described line drawing ruler is arranged in described macropore section, line drawing ruler is arranged on the blade plate corresponding with described aperture section by the jointed shaft that axis is vertically extending, the two ends of line drawing ruler are with big, the spacing cooperation of step surface between aperture section, namely this structure can be made ruler and use with doing protractor, but its drawn straight line is confined to the length of ruler, described use scope is wideless.

The open a kind of angle square of Chinese Patent Application No. 01237947.6, including main scale and secondary chi, one end of main scale is semicircle protractor, one end of secondary chi is hinged at the circle place of protractor with main scale, this structure both can make ruler with being also used as measurement and drawing angle, but the angle reflex angle more than 180 ° cannot be drawn by this mechanism.

Summary of the invention

This utility model is to solve prior art problem, it is provided that a kind of angle square, by arranging the main scale and protractor joined that slide, not only realizes ruler and angle measuring function uses simultaneously, and reach far-ranging purpose of drawing.

The technical solution adopted in the utility model is as follows:

A kind of angle square, including main scale, protractor and secondary chi, described main scale arranges centre zero scale line, arranging dentation chute between described centre zero scale line, described secondary chi one end is connected by hinge arrangement with described protractor central point, and described hinge arrangement one end arranges the slide block matched with described dentation chute, described slide block includes main body and R shape shell fragment, described main body offers groove, and described R shape shell fragment is arranged in described groove, and described R shape shell fragment matches with the tooth of described dentation chute.

Preferably, described main scale and/or secondary chi arrange magnifier.

Preferably, described main scale two ends arrange cushion block, and described secondary chi arranges clamping part away from one end of described hinge arrangement.

Preferably, described clamping part is take-up clip.

Preferably, described main scale is shrinkage-rule.

Compared with prior art, the beneficial effects of the utility model are:

Main scale of the present utility model arranges dentation chute, and the slide block being matched therewith is set on hinge arrangement, make protractor can move left and right by relative ruler with secondary chi, and all can relative to occurring angle to rotate between main scale, protractor, secondary chi three, protractor can be designed to 360 ° of protractors, this design is effective increases the scope drawing angle, and namely this structure can realize the drafting at 0-360 ° of angle; The groove that additionally slider body is offered is provided with R shape shell fragment, R shape shell fragment matches with the tooth in dentation chute, namely realize slide block to slidably reciprocate in dentation chute, and can after skid to a certain position, slide block is made to fix by R shape shell fragment and cooperating of tooth, now drawing the position of maintenance dose hornwork when angle or angle measurement to maintain static, effectively reduce error in measurement, this structural design is that those skilled in the art are not readily conceivable that.

Additionally, main scale and/or secondary chi arrange magnifier, magnifier can be used alone amplification font, effective raising use scope of the present utility model; Main scale two ends arrange cushion block, secondary chi arranges clamping part away from one end of hinge arrangement, increasing under the premise of this utility model whole height at cushion block, clamping part can be installed pencil and directly draw circular arc or circle, and this structural design makes this utility model play the effect of compasses; Clamping part is take-up clip, and take-up clip can adjust the openings of sizes of clamping part, is conducive to installing in clamping part different types of pen, improves the scope of application of the present utility model; Main scale is shrinkage-rule, and when main scale shrinks, now the length of secondary chi is more than the length of main scale, and this utility model can be made to draw circle, during main scale elongation, is effectively increased this utility model and measures straight line or draw the length of straight line.

To sum up, the disclosed a kind of angle square of this utility model has the functions such as use scope is wide, functional diversities, error in measurement are little, and hinge structure has substantive distinguishing features and marked improvement.

Detailed description of the invention

Embodiment one

As shown in Figure 1 to Figure 3, this utility model includes main scale 1, protractor 2 and secondary chi 3, protractor is 360 ° of protractors, main scale 1 is provided with centre zero scale line for shrinkage-rule and surface, dentation chute 4 is set between centre zero scale line, tooth in dentation chute 4 is round-arced tooth 8, secondary chi 3 lower left corner is connected by pivot structure 7 with protractor 2 central point, secondary chi 3 arranges magnifier 9, pivot structure 7 one end arranges the slide block matched with dentation chute 4, slide block includes main body 5 and R shape shell fragment 6, main body offers groove, R shape shell fragment 6 is fastened in described groove, R shape shell fragment 6 matches with round-arced tooth 8.

In the present embodiment protractor 2 as a whole with secondary chi 3 and can the relative movement of relative main scale 1, this structure can realize secondary chi 3 at 0-360 ° of all-directional rotation, and use this utility model can draw or measure 0-360 ° of all of angle;The fixed point that can realize protractor 2 and secondary chi 3 that cooperates of round-arced tooth 8 and R shape shell fragment 6 measures, and now the relative dentation chute 4 of slide block is fixing engaging, and effectively in prevention use procedure, protractor 2 and secondary chi 3 move back and forth the measurement or rendering error that cause.

Embodiment two

The present embodiment is essentially identical with the structure of embodiment one, the difference is that: as shown in Figure 4, main scale 1 two ends arrange cushion block 10, and secondary chi 3 is flexibly connected clamping part 11 away from one end of pivot structure 7, and clamping part 11 is take-up clip, and clamping part 11 inner clip is equipped with pen 12.

This structural design can realize the picture function of compasses, and the relative dentation chute of slide block 4 is fixing, and with pivot structure 7 center, namely the zero graduation line of secondary chi 3 is for round dot, with the scale value corresponding to pen 12 for radius picture circle or circular arc. This structure is conducive to increasing use scope of the present utility model.

Utilize technical scheme described in the utility model, or those skilled in the art is under the inspiration of technical solutions of the utility model, design similar technical scheme, and reach above-mentioned technique effect, all fall into protection domain of the present utility model.
