Abstract
The utility model discloses a telescopic ruler. The telescopic ruler is formed by sequentially splicing a plurality of sections of rulers from inside to outside through a pin shaft, the sides of the plurality of sections of rulers are all provided with scales, and the rulers are made of stainless steel or plastic. The number of the plurality of sections of rulers is 5 to 6, and the length of each section is the same. The measuring range of the plurality of sections of rulers is 20 to 25 centimeters. The minimum scale unit is millimeter. The cross sections of the plurality of sections of rulers are rectangular. After the plurality of sections of rulers are spread, the sides with the scales are sequentially connected and flush with one another. After the telescopic ruler is spread, the sides are flush, so that straight ruling is not affected on the basis of ensuring high measurement precision; and the telescopic ruler has simple integral structure, is convenient to carry, and can meet the length measurement operation of multiple occasions.
Description
Technical field
The utility model relates to a kind of stationery, and especially a kind of can freely stretching changes the chi of length.
Background technology
The ruler range ability of student's use at present generally arrives 15cm at 10cm, be used for length greater than the measurement of 20cm normally used be steel tape or leather measuring tape, the common defects of steel tape and leather measuring tape is that stretching, extension hardness is not enough, in measuring process, be easy to generate phenomenons such as bending, cause problems such as measurement result out of true, make troubles to surveying work.
The utility model content
The purpose of this utility model provide a kind of easy to carry, can accurately measure shrinkage-rule greater than 20cm length, measuring process is simple and convenient.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of shrinkage-rule wherein, is formed by the bearing pin grafting from inside to outside successively by number joint ruler, and the side of described number joint ruler is equipped with scale.
Above-mentioned shrinkage-rule wherein, is made by stainless steel or plastics.
Above-mentioned shrinkage-rule, wherein, described number joint rulers be 5 joints to 6 joints, the length of every joint is identical.
Above-mentioned shrinkage-rule, wherein, the range of described number joint ruler is 20cm to 25cm.
Above-mentioned shrinkage-rule, wherein, described scale least unit is a millimeter.
Above-mentioned shrinkage-rule, wherein, the xsect of described number joint ruler is rectangular.
Above-mentioned shrinkage-rule, wherein, a side that has scale after described number joint rulers launch connects successively and flushes mutually.
The utility model launches the back avris and flushes, and can not influence the straight flat of line on guaranteeing than the basis of high measurement accuracy, and one-piece construction is simple, and is easy to carry, can satisfy the linear measure longimetry work of multiple occasion.
Description of drawings
Fig. 1 is the structural representation after the utility model shrinkage-rule launches;
Fig. 2 is the structural representation after the utility model shrinkage-rule shrinks.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as qualification of the present utility model.
Please referring to illustrated in figures 1 and 2, a kind of shrinkage-rule of the utility model is formed by the stainless steel forging and pressing, and perhaps plastic injection-moulded making formed by bearing pin 11 grafting from inside to outside successively by number joint ruler 1, and the side of number joint ruler is equipped with scale 12.Number joint ruler 1 be 5 joints to 6 joints, the length of every joint is identical, range is 20cm to 25cm, the scale least unit be millimeter.The xsect of number joint rulers 1 is rectangular, and a side that has scale after the expansion connects successively and flushes mutually, is convenient for measuring and rules.During use, the number joint rulers 1 of this shrinkage-rule are curled up expansion by each bearing pin 11 successively from inside to outside, bearing pin 11 has the elastic force of compressing, and can make every joint ruler 1 stationkeeping after the expansion automatically.The scale of every joint ruler 1 avris is to arrange continuously, can directly read measured length, does not need to do and outer addition, and is easy to use.Ruler 1 uses up and must draw on ecto-entad ground, draws the back profile in and is that joint and be positioned at the profile that outermost also is the wideest ruler 1, because volume is small and exquisite, the place such as can be placed in the writing case arbitrarily.
The above only is the utility model preferred embodiment; be not so limit claim of the present utility model; so the equivalent structure that all utilization the utility model instructionss and diagramatic content have been done changes, and all is included in the protection domain of the present utility model.
Claims (7)
1. a shrinkage-rule is characterized in that, being pegged graft by bearing pin successively from inside to outside by number joint ruler forms, and the side of described number joint ruler is equipped with scale.
2. shrinkage-rule according to claim 1 is characterized in that, is made by stainless steel or plastics.
3. shrinkage-rule according to claim 1 is characterized in that, described number joint rulers be 5 joints to 6 joints, the length of every joint is identical.
