Abstract
The utility model discloses a novel gauge in which two functions of line drawing and circle drawing are combined. The novel gauge has the following advantages: simple structure, accurate dimension and small error. The line-circle dual-use gauge is composed of fives parts, namely a ruler, a supporting leg, a slider, a pen ring and a ruler plug. The ruler is similar with the common student ruler. Different measuring ranges and division values can be selected according to different requirements. The ruler is provided with grooves for mounting the supporting leg and the slider. The slider can move repeatedly in the groove of the ruler. When a circle is drawn, the slider is fixed at a corresponding dimension of the ruler. The supporting leg can be rotated to open and closed. The pen ring can be mounted and detached according to requirement. When a line is drawn, the supporting leg is closed and the pen ring is detached. When the circle is drawn, the supporting leg is rotated to open, and the pen ring is mounted. According to the line-circle dual-use gauge, the prior mode for drawing circle is changed. The line-circle dual-use gauge further has the advantages of high convenience in use, and high social benefit.
Description
Technical field
The utility model relates to a kind of student and uses drafting instrument, and especially a kind of straight line of will drawing is justified the dual-purpose type ruler that two kinds of functions are incorporated into one with drawing.
Background technology
In the existing drafting instrument, ruler and compasses separate, and ruler only is used for setting-out, and compasses are used for the picture circle.These two kinds of instruments come with some shortcomings in use, when the bowlder of wanting a diameter appointment of picture, must earlier measure certain-length with ruler, compasses are opened up into the corresponding angle of this length then after, just can draw circle.This picture circle mode is very inconvenient, loses time, and will fix after compasses are assigned to certain angle of wanting, tends in operation the situation that subtended angle changes occur, and the round size of coming that causes finally drawing changes, and has than mistake.At present, also lack a kind of two kinds of functions of picture straight line and picture circle that have concurrently in the drafting instrument of one.
Summary of the invention
The purpose of this utility model is the technological deficiency that solves existing ruler drafting instrument, provide a kind of easy to use, precision is high, the dual-purpose type ruler of good reliability, it both can be used for line and also can be used for the picture circle.When needs picture straight line, the dual-purpose type ruler can directly use, and its range and scale division value are identical with ruler with the student of national Specification.When needs picture bowlder, the ruler stiff end is opened, sliding slider is to required size, makes index line on it and corresponding size to it, just can be used for the circle of picture respective diameters size.
The utility model is made up of lattice chi, supporting leg, slide block, pen ring and chi plug.
Described lattice chi is improved by the pass student ruler and forms, and its range is the same with ruler with the student with scale division value.The lattice chi is marked with corresponding range and size, and scale division value is 1mm; The left end of lattice chi has a groove, and right-hand member has the groove of an outer narrow inner width, and there is a through hole groove middle, is used for installing supporting leg, and described groove is used for installing slide block.
Described supporting leg is a tapered rod, and its upper end is a cam structure, and there is a through hole middle, can be installed on the lattice chi by screw.In use, the supporting leg rotation that is equivalent to common compasses is taken out.
Described slide block is a trapezoid block, be installed in the groove of lattice chi, have a screwed hole and an index line in the front center position of slide block, adjusting slider is to different positions, make the corresponding different size scale of index line, this size value is exactly drawn diameter of a circle.Screwed hole and pen ring threaded engagement are used for fixedly pencil.
Described pen ring is a conical ring, and upper end open is big, and lower ending opening is little, and its effect is fixing pencil.On the pen ring double-screw bolt is arranged, the threaded engagement on double-screw bolt and the slide block when slide block moves to certain position, screws the pen ring and makes it be fixed on this position.When drawing bowlder the pen ring is installed on the slide block, when drawing straight line it is taken off.
Described chi plug is installed in the right-hand member of lattice chi, and its dative chi constitutes a pair of joinery and its construction, and its dative chi is tightly connected together, and anti-limited slip block skids off or comes off.
The beneficial effects of the utility model are: ruler and compasses are combined, both can be used for the picture straight line and also can be used for the picture circle, can select different functions for use according to different use occasions, change the mode of in the past drawing circle, the size of drawn circle is more accurate, and error is little.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is axonometric drawing of the present utility model;
Fig. 2 is front view of the present utility model;
Fig. 3 is the utility model lattice chi front view;
Fig. 4 is the utility model lattice chi left view;
Fig. 5 is the utility model supporting leg front view;
Mark among the figure: lattice chi 1, pen ring 2, slide block 3, chi plug 4, supporting leg 5.
The specific embodiment
A kind of line circle of the utility model dual-purpose type ruler is made up of lattice chi 1, pen ring 2, slide block 3, chi plug 4 and supporting leg 5.Lattice chi 1 is the main body of whole design, is carved with scale value on it, has a groove at lattice chi left end, and right-hand member has a groove, and a through hole is arranged in the groove.Described supporting leg lower end is a cone, and the upper end is a cam structure, and there is a through hole middle, and supporting leg 5 is installed in the groove by screw, and when supporting leg 5 was outwarded winding, the contact of the least radius place of maximum radius place dative chi 1 groove of cam was with supporting leg 5 chuckings.Groove is used for installing slide block 3, and groove adopts the structure of outer narrow inner width, and slide block 3 can move around in groove inside.Chi plug 4 is installed in the right-hand member place of lattice chi 1, and chi has four tenons beyond the Great Wall, assigns in the corresponding hole of lattice chi right section, and its effect is that anti-limited slip block skids off or comes off.
When drawing straight line, supporting leg 5 closures, pen ring 2 unloads, and this moment, ruler 1 was equivalent to ruler.When drawing bowlder, supporting leg 5 is outwarded winding, owing to be a cam structure above the supporting leg 5, when supporting leg was outwarded winding, the maximum radius of cam just was stuck in the least radius place of lattice chi groove, and supporting leg is fixed, the supporting leg axis is perpendicular to the straight flange of lattice chi, and the zero graduation line of fulcrum dative chi aligns; Then pen ring 2 is installed on the slide block 3, sliding slider 3 makes dimension line alignment on the index line dative chi on the slide block 3 to drawn diameter of a circle size place, and this moment, drawn circle was exactly the circle that is of a size of diameter with this.
The utlity model has the picture straight line and draw two kinds of functions of circle, can draw straight line and circle according to different needs, be characterized in simple in structure, easy to use, size is accurate, and error is little.
