Abstract

The utility model relates to a sectional symbol drawing ruler, which is composed of a fixed ruler and a main ruler which are hinged by a revolving pair. The utility model is characterized in that the main ruler can rotate corresponding to the fixed ruler, and the angular dimension can be read; the main scale is provide with through grooves with different structural characteristics; along the through grooves, various circles and any angle and parallel lines with various distances and various sectional symbols in accordance with the national standard 'GB4457.5-84' can be drawn, and angles can be measured. The utility model has the advantages of convenient operation, simple manufacture, and easy implementation. The utility model is an ideal drawing tool for drawing personnel.

Description

Sectional symbol drawing ruler

The utility model belongs to the mechanical drawing drawing instrument.

Practical at present drawing rule does not have Taoism draw magic figures or incantations to close the function of the various section symbols of GB4457.5-84.

The purpose of this utility model is to provide a kind of section symbols drawing rule, can take measurement of an angle, and draws various gardens, draws arbitrarily angled, various spacing parallel lines, and Taoism draw magic figures or incantations closes the various section symbols of GB4457.5-84.

The purpose of this utility model is achieved in that fixed ruler and main scale are hinged by revolute pair, main scale can rotate and read angle with respect to fixed ruler, maybe can the draw groove of section symbols such as meeting GB4457.5-84 " basis earth on every side ", " timber vertical section ", " timber cross section, " of the long groove that has the parallel lines that can draw on the main scale.

The purpose of this utility model also be to be achieved in that main scale (3) have 10-50 be parallel to each other, groove width equates, separation equates long groove (7).

The purpose of this utility model also be to be achieved in that the optimum structure feature of main scale be have 40 be parallel to each other, groove width equates to equate for the rectangle groove of 6mm and the groove of the section symbols such as meeting GB4457.5-84 " basis earth on every side ", " timber vertical section ", " timber cross section " that can draw for 2mm, separation.

Characteristics of the present utility model are grooves that main scale has the different structure feature, can draw fast and meet the various section symbols of GB4457.5-84, be easy to realize the standardization of section symbols, improve drawing efficiency and quality, parallel lines arbitrarily angled, various spacings fast particularly can draw, not only be fit to the picture section symbols, the tabulation lattice are also very convenient.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

Fig. 1 is a section symbols drawing rule schematic diagram.

As shown in Figure 1, the utility model is by fixed ruler (1), rivet (bolt) (2), main scale (3) is formed, fixed ruler (1) and main scale (3) are hinged by rivet (bolt) (2), fixed ruler (1) has-90 ° of-+90 ° of angle grooves (6) and position line (4), main scale (3) is carved with angle index line (5) with fixed ruler (1) connection, be carved with length groove (11) on one side, main scale (3) has 40 and is parallel to each other, groove width equates to be 2mm, separation equates be that the rectangle groove (7) of 6mm, main scale (3) also have to draw meets GB4457.5-84 " basis earth on every side ", " timber vertical section ", the groove (8) of section symbols such as " timber cross sections ", (9), (10).

Main scale (3) can rotate arbitrarily angled with respect to fixed ruler (1), can measure arbitrarily angled, draw arbitrarily angled oblique line, end along rectangle groove (7) can be drawn various circles, can draw the parallel lines of arbitrarily angled, various spacings and meet the various section symbols that GB4457.5-84 has parallel lines along groove (7), can draw respectively along groove (8), (9), (10) meets " earth around the basis ", " timber vertical section ", " timber cross section " and the section symbols such as " wooden plywoods " of GB4457.5-84.
