Abstract
A positioning numerical reading expansion rule belongs to a measuring tool for measuring residential area. Present measuring rules for measuring residential area comprise straight rules, ribbon tapes, measuring tapes, etc. and are inconvenient in measuring. Therefore, a numerical reading expansion rule is developed. The utility model is composed of a standard rule and two expansion rules, wherein, the scale line of the standard rule is arranged from small to large, and the scale line of the expansion rule is arranged from large to small. The expansion rule is pulled out when an object which is longer than the standard rule is measured, and the read-out number on the expansion rule corresponding to the end face of the standard rule is the length of the measured object. The rule has the characteristics of high measuring speed, high precision and easy use. The utility model has the advantages of high speed, high precision and convenient operation.
Description
The positional readings shrinkage-rule is a kind of measurer of measuring length, and particularly suitable is measured the area of dwelling house.
Measure the measurer of the area of dwelling house at present, have ruler, tape measure, tape measure etc. to survey chi, the thing that put the firmly chamber that has is more, and is very inconvenient during measurement, needs two, three people to work simultaneously sometimes.
Task of the present utility model is: develop a kind of positional readings shrinkage-rule of measuring convenience, accuracy of reading.
Task of the present utility model is that following method is finished: this chi is made up of the two large divisions, and a part is station meter, and the reading of its scale mark is arranged from small to large: a part is shrinkage-rule, and the reading of its scale mark is arranged from big to small.The corresponding reading of the end face of shrinkage-rule and station meter is the length of measured object.
Accompanying drawing is examples of implementation of the utility model.
Fig. 1 is the front elevation of positional readings shrinkage-rule.
Fig. 2 is the front elevation of station meter.
Fig. 3 is shrinkage-rule (a 4) front elevation.
Fig. 4 is shrinkage-rule (a 7) front elevation.
The positional readings shrinkage-rule is made up of station meter (1) and shrinkage-rule (4,7).The reading of the scale mark of station meter (1) is arranged from small to large, from 0 to 1700 millimeter; The reading of shrinkage-rule (4,7) scale mark is arranged from big to small, and shrinkage-rule (7) is from 3350 millimeters to 1700 millimeters, and shrinkage-rule (4) is from 5000 millimeters to 3350 millimeters; Station meter (1) and shrinkage-rule (4,7) all are that aluminium alloy is made, and xsect is a hollow rectangle, and shrinkage-rule (4,7) respectively has a drawing strickle guide (9,10).A loose pin (6) is arranged on shrinkage-rule (7), a spring (8) is arranged, spacing shelves (2,5) are respectively arranged on station meter (1) and shrinkage-rule (4) in the below of register pin (6).When measuring length greater than 1700 millimeters, the corresponding reading in side end face (3) of shrinkage-rule (4) or shrinkage-rule (7) and station meter (1) is the length of measured object.
If the length of measured object is during greater than 3350 millimeters, shrinkage-rule (7) has arrived extreme position, register pin (6) is ejected by spring (8), shrinkage-rule (7) is locked on the shrinkage-rule (4), continue to pull out a certain position of shrinkage-rule (4), shrinkage-rule this moment (4) and the corresponding reading of station meter (1) end face (3) are the length of measured object.
This survey chi has characteristics easy to use, that measuring speed is fast, precision is high.
Claims (5)
1, a kind of positional readings shrinkage-rule that is used to measure the area of residence is made up of station meter (1), shrinkage-rule (4,7), of the present utility model being characterised in that: the reading of station meter (1) scale mark is arranged from small to large, and the reading of the scale mark of shrinkage-rule (4,7) is arranged from big to small.
2, according to the positional readings shrinkage-rule of claim 1, it is characterized in that: station meter (1) and shrinkage-rule (4,7) all are that aluminium alloy is made, and xsect is a hollow rectangle.
3, according to the positional readings shrinkage-rule of claim 1, it is characterized in that: shrinkage-rule (4,7) respectively has a drawing strickle guide (9,10), and a loose pin (6) is arranged on shrinkage-rule (7), in the below of register pin (6) spring (8) is arranged.
4, according to the positional readings shrinkage-rule of claim 1, it is characterized in that: spacing shelves (2,5) are respectively arranged at station meter (1) and shrinkage-rule (4).
5, according to the positional readings shrinkage-rule of claim 1, the corresponding reading of station meter (1) end face (3) is the length of measured object.
