Abstract
The utility model is characterized in that the inner part of a parallel ruler 3 is dug and provided with a slide slot 8 which is parallel with the surface of the ruler, and the two ends of the slide slot 8 is provided with a group of straddling feet 9 and pulleys 4. The parallel ruler 3 are fixed on a drawing board 2 through the combination of a guide line 6 and a pulley 4 of the back surface of the drawing board 2. The utility model has the advantages of simple structure, legerity, convenient use, convenient carrying and storing. Because the guide line 6 is arranged on the back surface of the drawing board 2, the surface of the drawing board is neat, and the left side of the drawing board 2 is marked with Y shaft graduation which can clearly reflect the coordinate of a drawing point on the drawing board.
Description
The utility model relates to a kind of Graphing of Engineering instrument.
In the prior art, multiple structure draught machine is arranged, and utility model patent 92215391.4 is a kind of draught machines simple in structure, it has and general draught machine identical functions, and has simple in structure, easy to use, low cost and other advantages.Its shortcoming is to carry inconvenience, and part easily scatters and disappears when depositing.
The purpose of this utility model is to overcome above-mentioned defective, a kind of portable simple draught machine that divides chi and chart board, frame to form by pulley, parallel rule, rotation is provided, make it to have the identical function of draught machine and have simple in structure light and handy, and with convenient, advantage easy to carry and store.
The utility model is achieved in that and makes T-square into parallel rule 3 on the basis of utility model patent 92215391.4 simple and easy draught machines, two ends of parallel rule 3 be equipped with can prevent its horizontal play stride pin 9 and pulley 4.Guide line 6 and pulley 4 by the chart board back side are fixed on parallel rule 3 on the chart board, and parallel rule 3 reaches parallel mobile purpose up and down by means of pulley 4.Rotate graduated scale 1 and link to each other with parallel rule 3, by the chute on the parallel rule 8, rotate graduated scale 1 and can move freely, frame 5 is a chest, and the top and the case lid of chart board 2 are hinged, free to rotate, and the bottom of chart board 2 is provided with bayonet socket, and chart board 2 can be bearing on the casing.The left side of chart board 2 has one
Axle scale 7 can clearly reflect the position of drawing point on drawing.
Now in conjunction with the accompanying drawings embodiment of the present utility model is described as follows:
Fig. 1: the front view of the utility model portable simple draught machine.
Fig. 2: the side view of the utility model portable simple satin draught machine.
Dig a chute 8 parallel in the parallel rule 3 with the chi face, rotate have on the graduated scale 1 one can be in chute 8 parallel mobile slide block.Two ends of parallel rule 3 are equipped with one group and stride pin 9 and pulley 4, and parallel rule 3 is fixed by chart board 2 guide line 6 and 4 combinations of its pulley of the left and right sides behind.Frame 5 is a chest, and the top and the case lid of chart board 2 are hinged, and bayonet socket and casing supporting are equipped with in its bottom.
