Abstract

The utility model discloses a mould plate composed of the integral combination of a straight rule, a T-square, an angle square, a dimension scale, a protractor, a drawing gage, etc. and used for the user optionally adjusting various proportions. The mould plate can also be used as the straight rule to plot all classes of geometrical figures or other optional parallel lines. The utility model has the advantages of flexible operation, convenient portability and simple production process.

Description

Combined self-adjusting drawing pattern plate

The utility model is a kind of combined type self-regulated drawing template.

Present drawing template, ruler, angle square, T-square etc. all are independent existence, but be used again.Modulus figure on the drawing template lacks flexibility, and figure with the modulus typing of template is identical and figures that size is different just suffer restraints when drawing, and is just difficult more when particularly describing the parallel lines of the various spacings on the figure; The oversize easy flexural deformation of the blade of T-square is gone out to carry also inconvenient.

Task of the present utility model provide a kind ofly melt ruler, T-square, angle square, engineer's scale, half-round compasses, picture rule are the combined type self-regulated drawing template of one, be available for users to be adjusted to as required the template of various model specifications, removablely again select for use respectively as required.

Task of the present utility model is finished as follows: utilize transparent organic glass or hard high-strength transparence plastics to make a dedicated ruler, 4 sliding parts (two fixing sliding parts, two movable sliding pieces), step on the limit ruler for 2, an angle square, combining in certain sequence just to become a cover combined type self-regulated drawing template.

Describe in detail below in conjunction with accompanying drawing:

Fig. 1 is an overall schematic of the present utility model

Fig. 2 is movable sliding pieces plane (wherein A-A, B-B are respectively the profile in length and breadth of movable sliding pieces)

Fig. 3 is the profile of dedicated ruler.

Fig. 4 is the profile of the fixedly sliding part on the angle square (6)

Fig. 5 is a profile of stepping on the limit ruler

Fig. 6 is the A-A profile of Fig. 2

Fig. 7 is the B-B profile of Fig. 2

(1) is dedicated ruler among Fig. 1, have Yi Changkou on the dedicated ruler, on one side two limits on the Chang Kou limit are the millimeter rule, another side is the 1:2 proportional scale, the Chang Kou limit also is provided with chute and slides use for movable sliding pieces (2), (2), and detailed structure is seen Fig. 3.(3) are the inlets of movable sliding pieces that dark chute is cut open on the dedicated ruler, only need that the movable sliding pieces upper end is pushed in the chute lower end level and put into the installation that (3) locate just to finish movable sliding pieces, and the movable sliding pieces detailed structure is seen figure A-A and figure B-B.In addition, a millimeter scale is wherein carved on one side on two long limits on the dedicated ruler, and another side is carved the 1:2 scale graduation, uses when gage and inspection diagram linear dimension in the time of can be for combination, also can independently use when ruler and engineer's scale use.(4) be safety groove, it cooperates with pin on the movable sliding pieces installs guaranteeing drafting accuracy, and its purpose one is in order to allow the movable sliding pieces also can be along this groove slip except sliding in chute; The 2nd, two limits behind the dedicated ruler opening are caught allow two limits remain balance unlikely bending and influence drawing quality and result of use.(5), (8) for equating inequality two of scale, size steps on the limit ruler, these two rulers remove works as slide rule, outside slide bar uses, the inspection diagram linear dimension used when the interior sideband millimeter scale of two correspondent equal sizes was drawn for combination in addition, scale graduation is carved with as engineer's scale in the outside of two other correspondent equal, wherein a ratio is 1:3, another piece ratio is the described center of stepping on the limit ruler of 1:4, the circular hole that various spacing same diameter are arranged on the line is to be used for trace, circle and arc replace compasses to use, particularly disposable best results when drawing many manifolding figure and replace compasses to draw round or arc with carbon paper.(6) the angle square big angle for the band angle is that 60 ° of little angles are 30 °, its profile is trapezoidal, its two hypotenuse is prolonged the crossing right angled triangle that just can constitute, a millimeter scale is carved with on this angle square base, top margin is carved with the 1:6 scale graduation, the 1:5 scale graduation is carved with on the right, and the 1:7 scale graduation is carved with on the left side; In addition, the right also has a half-round compasses to use for measuring angle.(7), (7 ') for being fixed on the angle square (6) two fixedly sliding parts, detailed structure is seen Fig. 4, steps on the limit ruler and slides use for wearing.There is a straight interior mantle fiber circular hole by 8MM at sliding part (2), (2 ') and (7), (7 ') center on the line in addition, step on limit ruler and angle square and dedicated ruler so that be screwed.As long as be used as and will step on the limit ruler when T-square uses and be fixed on the angle square by screw, dedicated ruler can be along movable sliding pieces, and movable sliding pieces can be regulated as required for the user and gets final product along stepping on slide the arbitrarily template that constitutes various different sizes, model of limit ruler.(9), (9 ') are used for anchor pin on the movable sliding pieces and the special angle ruler groove of insuring.(10), (10 ') slide use for the chute at the place of slotting on the tenon on the movable sliding pieces and the dedicated ruler cooperates.(11) step on limit ruler use for the perforate of movable sliding pieces side for installing.(12) be interior mantle fiber circular hole on the movable sliding pieces center line.(12 ') are the interior mantle fiber circular hole on the fixing sliding part center line.

Claims

1, a kind of combined type self-regulated drawing template, it is characterized in that it by dedicated ruler, sliding part, step on limit ruler and the angle square combination forming that is slidingly installed.

2, combined type self-regulated drawing template as claimed in claim 1 is characterized in that fixedly sliding part, two are stepped on limit ruler and angle square combination forming that is slidingly installed by a dedicated ruler, two movable sliding pieces, two for it.

3, combination self-regulated drawing template as claimed in claim 2 is characterized in that the centre of dedicated ruler is opened long mouthful for the movable sliding pieces slip one.

4, as claim 2,3 described combined type self-regulated drawing templates, it is characterized in that two movable sliding pieces are installed on the dedicated ruler, two fixedly sliding part be installed on the angle square, with two step on the limit ruler respectively with two on two movable sliding pieces on the dedicated ruler and the angle square fixedly sliding part to flexibly connect be one.
