Description

The co-ordinate-type multipurpose plotter

A kind of co-ordinate-type multipurpose plotter belongs to the drawing article technical field, is mainly used in the various charts of quick drafting and carries out plotting.

Traditional drawing article has ruler, set square, parallel rule, T-square, curve ruler etc. in prior art.Though they have advantages such as simple in structure, easy to use, can only draw better simply figure, and accuracy is low, plotting speed is slow.Through consulting existing patent gazette, finding has the innovation and creation of many this respects in recent years, but the purposes that has is single, the complex structure that has, and the operating technology level that has is too high, uses inconvenience, so do not see and put goods on the market.

It is a kind of simple in structure that the purpose of this utility model is to provide, easy processing and fabricating, easy and simple to handle, easily grasp, but not only mechanical graphics figure but also can carry out plotting, also can draw various curve maps such as thermodynamics, electronics, be convenient to be used the co-ordinate-type multipurpose plotter that the fast accuracy of plotting speed is high with traditional drawing article.

According to geometrical principle and drawing requirement, at the subject matter that exists in the prior art, basic design of the present utility model is: form a rectangular frame by interior scale in length and breadth along the band chute, in this framework, adorn the chi of slip in length and breadth that a two ends band can move along the chute in the framework, all establish guide groove in the middle of this ruler, its center is installed for inserting the crosshead of drawing pen vertical tube on their square crossing points, so both can draw horizontal line fast, vertical line, can look for point location according to coordinate figure again, other joins and holds one by one on the porose pen tube that is enclosed within crosshead, the ruler of line channel dress paintbrush is driven in the centre also can draw the garden, garden arc and oblique line, join the known protractor of its center borehole jack on the slotting vertical tube of crosshead again, also can measure.

Co-ordinate-type multipurpose plotter described in the utility model, by fixedly horizontal staff [1] and [2] up and down, about fixing vertical scale [3] and [4] and at place, four angles they are fixedlyed connected and to become the fixedly corner bracket of rectangular frame [8] formation, it is characterized in that this multipurpose plotter, its above-mentioned up and down and about fixing horizontal, the interior of vertical scale [1～4] respectively has one straight line chute [9] along the place, all have moving chi [5] of sideslip and vertical slip chi [6] that line channel [10] two ends all have the guide rail [12] that can slide along above-mentioned chute [9] in the middle of in the framework that their are formed, also being provided with, and the crosshead [7] that its center is a slotting vertical tube [11] is installed at their square crossing point.

Above-mentioned upper and lower and about upper and lower and left and right each edges of the inward flange of fixing horizontal, vertical scale [1], [2], [3], [4] and horizontal stroke, vertical slip chi [5] and [6] all can paste each chi with adhesive sticker and be long measure, crossfoot mark longitude linear foot mark latitude, crossfoot mark pressure P linear foot mark volume V, crossfoot mark temperature T linear foot mark pressure P, crossfoot and mark the electric current I linear foot and mark any scale among the voltage V etc. according to concrete purposes.

Above-mentioned chute [9] and can all both can be the right angle along their lower end of guide rail [12] of its slip and also can be acute angle.

Above-mentioned crosshead [7] center insert on its outer wall of a vertical tube [11] also can be as required at any time discrete separately the end of suit in order to picture garden, garden arc and oblique line have the internal diameter hole identical with this external diameter of pipe, the centre has additional ruler [13] and/or the center additional amount hornwork [14] in order to measuring angle and oblique line directions with holes of straight trough.

The utility model has the advantages that: this patent product comes down to the organic assembling of several rulers, so it is simple in structure, also easy processing and fabricating, both can be used for the mechanical graphics engineering drawing, also can draw pressure, PRESSURE-VOLUME RELATION figure in the thermodynamics, temperature in the meteorology, pressure dependence figure, electric current in the electronics, voltage relationship figure, current resistor graph of a relation or the like, also can carry out plotting, therefore purposes is very extensive, and plotting speed can improve 4～5 times than drawing with traditional articles for use, can improve accuracy simultaneously.

Accompanying drawing 1 is one of the utility model most preferred embodiment assembling back bulk shape structure schematic top plan view; The ruler schematic top plan view that Fig. 2 can add for one of the utility model change embodiment, Fig. 3 is the two protractor schematic top plan view that can add of the utility model change embodiment.

Fixing horizontal staff on 1 among the figure, 2 times fixing horizontal staffs, the fixing vertical scales in 3 left sides, 4 right fixing vertical scales, chi is moved in 5 sideslips, 6 vertical slip chis, 7 crossheads, 8 fixing corner brackets, 9 straight line chutes, 10 line channels, 11 insert a vertical tube, 12 guide rails, 13 rulers that add, 14 protractors that add.

Further describe architectural feature of the present utility model as follows with most preferred embodiment in conjunction with the accompanying drawings: with the upright chi length of two long two short four lucite is upper and lower fixedly horizontal staff 1 and 2, fixing vertical scale 3 and 4 about short is, the size of its size and the drawing board that matches with it adapts, their place, nearly inside edge all offers straight line chute 9, being bonded them by the fixedly corner bracket 8 of four lucite matter becomes rectangular frame, and this framework just in time is stuck on four sides of drawing board; In said frame, be provided with lucite matter two ends and all have and above-mentioned straight line right angle chute 9 the match guide rail 12 that can slide along this groove and the moving chi 5 of sideslip and the vertical slip chi 6 of middle band guide groove 10, the crosshead 7 of the lucite matter of the pen tube 11 that its center has stainless steel tube matter is installed at the place, crosspoint that they intersect vertically.

Change as present embodiment:

1, straight line chute 9 and guide rail 12 all can change acute angle into;

2, each edge up and down of the inward flange of all nonadjustable signals and slip chi all can be according to different purposes with scales such as long measure, longitude and latitude, P-V, temperature, pressure, current/voltage, current resistor on the pressure sensitive adhesive;
