Abstract
The utility model discloses a universal drawing rule for garment cutting, which comprises a main rule with a middle belt slot and a sliding rule, wherein the main rule is a straight rule and a curved rule, and the upper surface and the lower surface of the main rule are marked with a common scale and a city scale. The main scale is marked with the scale with different proportions, the slide scale is formed by connecting an upper scale and a lower scale by a sliding block, the upper scale and the lower scale synchronously slide in the main scale groove by the sliding block, the slide scale is provided with a vernier, a numerical value of a certain scale is aligned by the vernier, the calculated proportional numerical value can be checked from the corresponding vernier of the ruler, and the calculation is very convenient.
The ruler integrates the functions of straight ruler, curved ruler, calculation, official system and city system conversion, so that the cutting and drawing are fast and accurate, and the ruler is suitable for calculation and drawing of different cutting methods.
Description
The utility model relates to a kind of chi, is the omnipotent drawing rule of a kind of tailoring specifically.
General cutting clothes are used alternatingly sometimes with ruler, trisquare, use up one and look for another inconvenience, tailoring often need be calculated in addition, as every of the front and back sheet of trousers is respectively a certain numerical value of four of hip circumference/add and subtract again and again, if hip circumference is not can be by four values that divide exactly with regard to bad mental arithmetic, also having often needs metric system, Chinese system of weights to convert when cutting cloth, and the number that has is bad to convert with mental arithmetic.
The purpose of this utility model is to provide a kind of multipurpose ruler that collects ruler, trisquare, public affairs, Chinese system of weights conversion, is calculated as one, makes things convenient for the cutting personnel to use.
The utility model is made up of a main scale and the slide rule that can slide on main scale, one side of main scale is ruler, ruler is trisquare on one side relatively, the upper and lower surface of ruler indicates metric system, city's scale making and corresponding one by one respectively, the slide rule groove is arranged on the main scale, dwindle a certain proportion of engineer's scale on the main scale in addition; Slide rule has two chis up and down, they are respectively in the outside of main scale top and bottom, slide rule two chis is up and down used and can be connected at the slide block that the slide rule groove moves, make it to become one, can slide simultaneously, fractional expression and the vernier line of desiring the demagnification number are arranged on the slide rule, have the corresponding desire demagnification of locating to count vernier by ruler one side on the slide rule in the calculating ratio.
On the main scale cutting pithy formula can also be arranged.
Advantage of the present utility model is to be convenient to calculate, converts, draws cutting figure quickly and accurately, and is applicable to the calculating and the drawing of different method of cutting out, indicates pithy formula; Make the beginner more convenient.
Fig. 1 is the utility model embodiment schematic diagram.
Main scale (1) is ruler (3) on one side as seen from Figure 1, another side is trisquare (4), the centre is slide rule groove (5), the top and bottom of ruler indicate metric system scale (13) and city's scale making (12) respectively, also indicate the engineer's scale (7) and the cutting pithy formula (8) of different proportions such as 1:4 and 1:5 on the main scale; Slide rule (2) is made for transparent organic glass, it has two chis up and down, respectively in the outside of main scale upper and lower surface, its middle being linked to each other with two chis by slide block makes it to form one and slip simultaneously, have on the slide rule and dwindle 4 times of vernier (10) and vernier lines (9) that are calculating actual size 1/4, also have 1/4 vernier (11) by ruler one side, this vernier is to indicate the result of calculation size.The slip slide rule makes the vernier line (9) of vernier (10) aim at a certain numerical value of 1:4 engineer's scale, and this numerical value is removed institute's value can be found this numerical value on ruler vernier (11) result of calculation by 4.Can also add some equally to vernier, as adding a pair of 1/5 vernier again, just can calculate 1/5 of a certain value with the 1:5 engineer's scale on the main scale what are, a pair of vernier and its corresponding engineer's scale (1:4) of calculation 1/4 are used same color, and a pair of in addition vernier and corresponding engineer's scale are painted with another kind of color.During use if will calculate 1/4 o'clock of 30 cun of chest measurements, " 30 " position of 1:4 engineer's scale aimed at the vernier line of vernier (10) (9) by elder generation's slip slide rule, look into the vernier line of 1/4 vernier (11) of color right ruler numerical value be exactly " 7.5 ", the pairing numerical value in its back side is the conversion numerical value of metric system and Chinese system of weights.This calculating all can be done in public Chinese system of weights two sides, and (6) refer to that main scale has upper and lower surface, and (14) are the trisquare scale.
Claims (3)
1, the omnipotent drawing rule of a kind of tailoring, it is characterized in that it is made up of main scale (1) and slide rule (2), main scale is ruler (3) on one side, relative trisquare (4) on one side, the ruler upper and lower surface indicates metric system scale (13) and city's scale making (12) respectively, and corresponding one by one, a slide rule groove (5) is arranged on the main scale, the upper and lower surface of main scale (1) also has respectively and dwindles a certain proportion of engineer's scale (7); Slide rule (2) is two chis up and down, they are respectively in the outside of the top and bottom of main scale (1), two chis up and down of slide rule link with the slide block that can slide in groove (5), slide rule is marked with vernier (10) and the vernier line (9) of desiring the demagnification number, has the corresponding desire demagnification that calculates the location in proportion to count vernier (11) by straightedge rule one side on the slide rule.
2, the omnipotent drawing rule of tailoring according to claim 1 is characterized in that its main scale is marked with the cutting pithy formula.
3, the omnipotent drawing rule of tailoring according to claim 1 is characterized in that its slide rule is made of transparent material.
