Description

Combined mapper

Technical field

The present invention relates to the drawing appliance in the study and work, particularly integrate the combined mapper of set square, ruler, protractor.

Background technology

In study and work, particularly the industry science student in study, engineering technical personnel at work, use drawing instruments such as chart board, T-square, set square and protractor through regular meeting.Existing these drawing instruments generally all are single-pieces independently, and number of packages is many, and wedge angle is many, carry, keeping is inconvenient, simultaneously, the cost height, instrument disperses, use inconvenient, dimensional accuracy and quality that influence is drawn.In addition, traditional chart board is made of timber, be exposed to the sun by sunlight or drenches with rain and make moist, and all may produce distortion or goes rotten, even can be subjected to the destruction of mouse etc.

Summary of the invention

Purpose of the present invention is exactly at existing drawing appliance above shortcomings, a kind of use is provided, carries, take care of combined mapper easily.

The object of the present invention is achieved like this, and combined mapper is characterized in that the chart board and main scale, the auxilliary chi installation that are made of plastics connect to form, and main scale is horizontally installed on the chart board face, and auxilliary chi vertically is arranged on the chart board face; Be provided with guide groove around the chart board, a spike is respectively established at side two ends of chart board, and the chi head of main scale is provided with and is put in guide rail that slides in the guide groove and the button of locating with guide groove, is provided with a chute in the middle of the blade of main scale; Auxilliary chi is made up of ruler and chi card, one end of ruler is provided with the protractor of band deep-slotted chip breaker, the protractor center is crossed bearing pin with the chi cartoon and is connected, and bearing pin below is provided with guide rail and is inserted in the chute on the main scale, is provided with button with the deep-slotted chip breaker location corresponding to the chi card of deep-slotted chip breaker.

Chute both sides on the described main scale are provided with chi, Song's chi scale clearly.Described plastics are the PVC material.Main scale and auxilliary chi adopt transparent material to make.

The present invention is simple and reasonable, manufactures easily, and cost is low, and it is convenient to use, carry, take care of.Guide groove around the chart board so that main scale is made parallel sliding along guide groove, two spikes of chart board one side, prop up during use make chart board form one domatic, utilized principle of human engineering, to alleviate illustrator's sense of fatigue.The chi head of main scale has guide rail and button, and guide rail can make ruler move along guide groove, and the chi head of main scale, chi tail can be provided with guide rail, parallel sliding synchronously about assurance, and button can be used for fixing the position of ruler.Open a chute in the middle of the blade, convenient auxilliary chi horizontally slips along this groove, and carves the ruler scale of the Song dynasty and the Qing Dynasty in the groove both sides, so that the usefulness of ancient building design.Auxilliary chi is made up of a ruler and a chi card, and chi card and ruler are hinged, and makes ruler can freely rotate and read the angle that ruler rotates, and presses the button when angle is determined, locks in the deep-slotted chip breaker of ruler, promptly locks ruler and chi card.The guide rail that the hinge below is provided with can horizontally slip auxilliary chi along the chute of main scale.Thereby can draw the parallel lines and the perpendicular line of any direction.Auxilliary chi not the time spent desirable down or rotate to the position parallel with main scale.This combined mapper has the function of chart board, T-square, ruler, set square, protractor concurrently, and is not only light but also firm, long service life.Simultaneously saved timber again, helped environmental protection, can be widely used in student, engineering technical personnel's use, vast market prospect has been arranged.

Fig. 2 is laterally (A-A among Fig. 1) sectional structure synoptic diagram of chart board of the present invention;

Fig. 3 is a main scale structural representation of the present invention;

Fig. 4 is an auxilliary chi structural representation of the present invention;

Fig. 5 is a main scale afterbody sectional structure synoptic diagram of the present invention;

Among the figure: 1 chart board, 2 guide grooves, 3 main scales, 4 chutes, 5 chi cards, 6 buttons, 7 guide rails, 8 buttons, 9 chi heads, 10 bearing pins, 11 rulers, 12 spikes, 13 deep-slotted chip breakers.

Embodiment

Chart board 1 is made by PVC, around chart board, make a guide groove 2 respectively, so that main scale 3 is made parallel sliding along guide groove, a spike 12 is respectively done at two ends in a side of chart board, prop up during use and make one of chart board formation domatic, utilized principle of human engineering, to alleviate illustrator's sense of fatigue.Main scale 3 is made up of chi head 9 and blade, fixes with rivet, and guide rail 7 and button 8 are set on chi head 9, and the guide rail on the main scale can make ruler move along guide groove, and 8 on button is the position that is used for fixing main scale.(also can guide rail 7 be set simultaneously, synchronous parallel sliding about assurance) at the chi tail.The blade of main scale 3 is made (as transparent plastic, organic glass etc.) with transparent material, opens a chute 4 in the middle of the blade, and convenient auxilliary chi horizontally slips along this groove, and carves the ruler scale of the Song dynasty and the Qing Dynasty in the chute both sides, so that the usefulness of ancient building design.In addition, this groove also can be done " ungraduated ruler " (the soft pen chi of traditional Chinese Painting) use.Auxilliary chi is made up of a ruler 11 and a chi card 5, and an end of ruler is made the arc plate that is the protractor shape, is carved with angle on the arc plate, and drives a deep-slotted chip breaker 13.The chi card is made (as transparent plastic, organic glass etc.) with transparent material, and chi card 5 and ruler 11 are hinged by bearing pin 10.The base of chi card 5 is parallel with the limit of main scale 3, one 0 degree lines (can use red line) are set on the chi card 5, ruler can freely rotate around bearing pin 10, can read the angle that ruler rotates from red 0 line, when determining, angle presses the button 6, button 6 is locked in the deep-slotted chip breaker 13 of ruler, locking ruler 11 and chi card 5, and the angle line draws.Below bearing pin 10, establish a guide rail, auxilliary chi can be horizontally slipped along the chute of main scale.Thereby can draw the parallel lines and the perpendicular line of any direction.Auxilliary chi not the time spent desirable down or rotate to the position parallel with main scale.
