Abstract
A multipurpose combined calculating ruler is composed of a ruler body. The gauge is characterized in that the gauge is divided into a fixed gauge and a movable gauge, one end of the movable gauge is provided with a shaft which is movably connected with the center of a sliding block, and the movable gauge is provided with a locking device of the fixed gauge, the movable gauge and the sliding block. The slide block can be inlaid in the middle groove of the fixed rule to drive the movable rule to make linear motion on the fixed rule, and the movable rule has the advantages of simple structure, wide application, portability and convenient use, can be used for drawing included angle lines, parallel lines, circular arcs, radioactive rays and the like of straight lines and any angles, can replace various drawing instruments such as a T-square, a set square, a folding rule, compasses, a protractor and the like to use, and is an indispensable good helper in drawing.
Description
Scale is calculated in a kind of multipurpose combination, is made up of ruler, is mainly used in the technical staff of various field of engineering technology, and the student of universities, middle and primary schools drawing, tabulation and data are handled, and belong to stationery category.
The drawing instrument that present all kinds of technical staff, the student of universities, middle and primary schools use is a lot, as T-square, ruler, folding rule, set square, garden rule etc.But all can not be conveniently used for drawing various angle lines, parallel lines, garden arc and multiple radioactive ray, use several instruments just can achieve the goal simultaneously, data computing is handled also must rely on computational tool, and this has brought a lot of troubles to working and learning.
The purpose of this utility model is exactly the troublesome problem that will solve in above-mentioned drawing and the data handling procedure, uses a drawing instrument to achieve the goal.
This practical scale that is characterised in that is made up of scale and moving chi, and moving chi one end has axle to be connected with the slide block central movable, and has the locking device of moving chi, scale and slide block, and the medial launder that slide block can be inlaid into scale drives moving chi moving linearly on scale.Wherein an end of scale is provided with half garden rule, has groove on the corresponding wall in the medial launder, and there is scale on the medial launder both sides.Slide block can be inlaid on two mosaic surfaces of scale medial launder fin, and fin is bumped in the groove of corresponding wall of scale medial launder, slide block can be in scale moving linearly.The end of moving chi and the coaxial end of slide block is a garden shape, is the garden heart with the axle center, is provided with full garden rule, on moving two straight flanges of chi scale is arranged, on the moving chi center line several through holes are arranged, moving chi and slide block are fixed with projection with the scale uniform thickness with the other end of one side, move chi and make with transparent material.
Below by description of drawings architectural feature of the present utility model and using method:
In the accompanying drawing, 1 scale, 2 scale medial launders, 3 scales, half garden rule, 4 slide blocks, 5 moving chis, 6 moving chi projections, 7 moving chi center line through holes.During use, scale 1 is put in the suitable position of the paper that requires drawing.As drawing parallel lines, can make slide block 4 moving linearly in the scale medial launder with moving chi 5 and slide block 4 lockings, parallel lines can draw.As require to draw and have the straight line of certain angle, can in proper range, rotate moving chi 5, by the scale on the rule of full garden, required angle line can draw.As drawing the garden arc, scale 1 and slide block 4 lockings can be rotated moving chi 5, can utilize the through hole 7 on the moving chi to draw arc.As drawing radioactive ray, scale 1 and moving chi 5 can be used, and rotate moving chi 5 and can achieve the goal.Use as making slide ruler, can overlap with scale 1 moving chi 5, moving chi 5 of locking and slide block 4 get final product.
The utility model has the advantages that simple in structurely, have only two rulers to combine.Purposes is many, can draw straight line, angle line, parallel lines, garden arc and radioactive ray etc.Easy to use, a multi-functional combination is calculated scale and can be replaced multiple drawing instruments such as T-square, set square, folding rule, protractor and garden rule, can also carry out data computing as slide ruler and handle.And being easy to carry, is engineers and technicians, the student's of universities, middle and primary schools optimal selection.
Embodiment:
With the lucite is raw material, makes scale and moving chi.The long 200mm of scale, wide 40mm, thick 3mm, medial launder are split into wide 20mm, dark 1.5mm, groove two arms bottom is driven the groove of 0.5 * 0.5mm again into, and the end is half garden rule, and medial launder is opened to the diameter of half garden rule.The moving long 240mm of chi, wide 40mm, thick 1.5mm, an end are diameter and the wide identical garden shape of scale, the center is that the square slide block center of 20mm is connected with hollow screw axis and each length of side, with sunk screw precession hollow screw axis, adds wing nut on the hollow screw axis.The fin that 0.5 * 0.5mm is arranged on the slide block four edges can directly be bumped into scale medial launder moving linearly, and the moving chi other end and slide block are with having the thick boss of 3mm on the one side, and size is 30 * 40mm, and having row's diameter on the moving chi center line is the through hole of 3mm.The study chi that scale can be used as the student of universities, middle and primary schools is calculated in the multipurpose combination of making, and also can satisfy when various professional and technical personnel draw tabulation and use.
Claims (4)
1, scale is calculated in a kind of multipurpose combination, ruler by the band scale is formed, it is characterized in that this scale is divided into scale and moving chi, moving chi one end has axle to be connected with the slide block central movable, and having the locking device of moving chi, scale and slide block, slide block can be inlaid into the scale medial launder and drive moving chi moving linearly on scale.
