Abstract
The utility model relates to a simple quick reading device for an instrument with a multi-range arrow or a cursor indicating reading. The utility model changes the fixed graduation on the existing instrument to a movable graduation belt labeled with graduations corresponding to the entire measuring range. The utility model is provided with a driving device to connect a range switching disk and the graduation belt. The graduation belt correspondingly moves along with the changed measuring range. Thus the graduation corresponding to the given measuring range is displayed in a window of the front face of the instrument. The unused graduation of the given measuring range is at the outer part of the window and is not displayed temporarily. The utility model can read out the reading number directly and quickly from the point of the arrow or the cursor indicating point. The utility model has the advantages of complete graduations, terse dial, quick and accurate reading, and no need of conversion, and the utility model is free from the influence of other graduations and is difficult to misread.
Description
The utility model is the simple device about the meter reading of multirange pointer or cursor indication.
Index dial on the instrument of used multirange pointer or cursor indication is fixed, and be marked with this and show the corresponding scale of some range, but because range is many, the area that mark can be spent is limited, does not often put on the scale of whole ranges, has both made like this, scale also seems in a jumble, when using a certain range to measure, needs to find out the scale corresponding with range from numerous scales and comes reading, often there is not corresponding scale, just need to convert, time-consuming, take sb's mind off sth, easily misread, often make mistakes.
The utility model adds and improves some devices and eliminated above-mentioned drawback on now with instrument at above-mentioned drawback, please understands the utility model in conjunction with the accompanying drawings.
An additional cover gearing (4,5,6,12,13) couples together range changeover panel (8,15) and removable scale band (1,9), utilizes the rotation of range changeover panel to drive packaged type scale band by gearing.This scale band is marked with the pairing scale of whole ranges with this table, all need rotate the range changeover panel before each the measurement and set range, this with now use instrument identical, when rotating, it is corresponding mobile that gearing drives packaged type scale band, when configuring a certain range, when the range changeover panel has been fixed on the relevant position, the scale band just also is fixed on simultaneously the pairing scale of this range is shown in window (2,10) Nei position, and other does not need the scale of reading all can not show not in window, so, eye-catching, intuitively and promptly indicate reading from pointer or cursor, the interference of other scale then disappears, and is difficult for misreading.
Be with used multirange instrument difference: range changeover panel (8,15) is provided with power wheel (14), and belt pulley (7) utilizes they and gearing (4,5,6,12,13) to couple together; Another difference is that the scale of instrument all is marked on the scale band (1,9), and it is corresponding one by one with range, and on the instrument front, do not need indexing and need offer one with the scale band on the window (2,10) that adapts of scale, its adaptability refers to manifest set range this moment on the range changeover panel scale in window, and other scale can not appear.
Specific design of the present utility model and the installation foundation instrument of adorning.The move mode of scale band is by the conversion regime decision of range changeover panel, changeover panel is continuously that rotary type (refers to and can genially rotate more than the week continuously counterclockwise, as among Fig. 1 8) then the scale band must be capable of circulation mobile, as among Fig. 11, at this moment used material should have flexible characteristic, and headtotail forms ring-type, the outside is printed on scale, in wear two axles (3); Changeover panel is that one-directional rotation (refer to cannot genial counter clockwise direction rotate continuously more than the week, as among Fig. 2 15) can adopt unidirectional portable scale band, and as among Fig. 29, the front is printed on scale, and both sides are provided with slide rail (11).The effect of gearing be the rotation with changeover panel be delivered on the scale band and make its with the rotation of changeover panel the shift position, so that its scale that exposes in window is corresponding with the range of changeover panel indication this moment, the any range that can set that requires changeover panel to set, the corresponding scale on its scale band all shows in window.Its concrete structure can be power wheel (12,13), driving-belt (5) and drive pulley (6,7), and 4 is that two umbrella shape power wheels change transmission direction to drive scale tape spool (3) among Fig. 1, requires must not skid in transmission.
Claims (2)
1, on a kind of instrument that the range changeover panel is arranged that is installed on multirange pointer or cursor indication reading, scale is the easy reading device of automatic setting with the range conversion, it is characterized in that by the packaged type scale band (1,9) that indicates each range scale, axle (3) or slide rail (11), gearing (4,5,6,7,12,13,14), window (2,10) is formed with the range changeover panel that is connected with gearing (8,15).
2, by the described device of claim 1, it is characterized in that indicating the packaged type scale band (1,9) of whole range scales, locate with range changeover panel (8,15).
