Description
Technical field
The utility model relates to a kind of drawing instrument, especially a kind of parallel engineer's scale.
Background technology
When map making and other planes, need actual range to reduce (or expansion) by certain ratio, then be drawn on drawing.At this moment, the ratio of map range and corresponding actual range will be determined.The map range of one width figure and the ratio of actual range, be called the engineer's scale of this width figure.In drawing process, just need the engineer's scale using various special ratios; But when parallel lines drawn by usage ratio chi, need to use other instruments to coordinate, operation comparatively bothers, and easily causes error because moving the instrument of reference because of carelessness, make troubles to drafting parallel lines.In addition, often kind of engineer's scale all only has specific a kind of ratio at present, need bulk/volume buying with the use of, cost is higher.
Utility model content
For the problems referred to above, the utility model provides a kind of parallel engineer's scale, chi body arranges two rollers, also added the fixture of fixing rotating direction, solve the problem causing error because of careless moving ratio chi, and multiple specific engineer's scale is provided and conveniently sees the magnifying glass of scale.
The technical scheme adopted for realizing the utility model object is:
A kind of parallel engineer's scale, comprise chi body, involution plate and roller, chi body is provided with graduated three the chi faces of picture, and chi body two ends are provided with the race with opening, and race inner transverse is provided with a back shaft; Involution plate is connected to the two ends of chi body and seals the opening of race; Roller one side is provided with swivelling chute, and another side is provided with holddown groove, and involution plate is provided with the through hole matched with holddown groove, and through hole is supporting a fixture.
Further, roller is arranged in race, and its swivelling chute is inserted with support bar, and thus, roller can rotate around back shaft, impels and moves horizontally chi body.
Further, fixture is cuboid or tri-prismoid, and thus, when fixture inserts holddown groove, race can not rotate around back shaft again.
Further, involution plate is bonded in chi body two ends by viscose, or is connected to chi body two ends by latch and pin-and-hole, thus, is convenient to, by involution plate and the assembly and disassembly of chi body, roller to be taken out from race.
Further, chi face is provided with chute, coordinates slidably slide block in chute, and slide block is connected through the hinge one for the magnifying glass of magnification ratio scale, thereby, it is possible to clearly observe the numerical value on scale.
The structure of the utility model to existing engineer's scale is improved, chi body arranges two rollers, also added the fixture of fixing rotating direction, solve the problem causing error because of careless moving ratio chi, and multiple specific engineer's scale is provided and conveniently sees the magnifying glass of scale, for study, work bring convenience, be applicable to various drawing occasion.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
The structure of the parallel engineer's scale of the utility model a kind of embodiment as shown in Figure 1.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of parallel engineer's scale, comprise chi body, involution plate and roller, chi body is provided with three the chi faces being decorated with different scale, both sides, each chi face are provided with different scale numerical value, and chi body two ends are provided with the race with opening, race inner transverse is provided with a back shaft; Involution plate is bonded in the two ends of chi body and seals the opening of race; Roller one side is provided with swivelling chute, and another side is provided with holddown groove; Roller is arranged in race, and its swivelling chute is inserted with support bar; Involution plate is provided with the through hole matched with holddown groove, and through hole is supporting a fixture, and fixture is tri-prismoid, and thus, when fixture inserts holddown groove through through hole, race can not rotate, thereby, it is possible to move horizontally chi body around back shaft again.
Fixture in the utility model can also be cuboid, and its through hole coordinated and holddown groove are the cuboid agreed with it, and its structure equally also can impel roller to fix.
During the utility model assembling, first roller is put into race, be inserted in swivelling chute by back shaft simultaneously, then involution plate is bonded in chi body two ends and seals the opening of race, at this moment, roller can be stuck in race by involution plate, avoids it to depart from race; The chi face choosing needs again carries out measuring and setting-out, meanwhile, can facilitate attachable mechanical stage body by roller, when needing fixed idler whell, fixture is inserted in the holddown groove of roller.
These are only a kind of embodiment of the present utility model, to those skilled in the art, under the prerequisite not departing from the utility model creation design, also can carry out some distortion and improvement, these all belong to protection domain of the present utility model.
