Described calibration steel tape; It is characterized in that described chi band is made up of two parts up and down, top is the footage number that breaks, and the bottom is continuous footage number; The continuous footage number threshold value of bottom is zero, the threshold value of disconnected footage number for the length at the right angle, left end starting point to housing footing right side of contrast footage number with.
Described calibration steel tape is characterized in that described elongated slot top is provided with the perspective window, and the perspective window is arranged on disconnected footage number one side of chi band.
Described calibration steel tape, the scope that it is characterized in that the disconnected footage number threshold value of described chi band is 3-50cm.
Described calibration steel tape is characterized in that described perspective window is provided with lens.
Described calibration steel tape is characterized in that described housing below is provided with scale mark, and the scale mark of the rightmost side is zero, and right-to-left increases progressively successively.
Described calibration steel tape is characterized in that the below of described housing and elongated slot is provided with continuous scale mark, and the scale mark of the rightmost side is zero, and right-to-left increases progressively successively.
The utlity model has following advantage:
1) housing footing right side is set to the right angle, when measuring, in can being convenient for measuring apart from and do not need bending chi band, directly footing setting-out after measuring in addition along the housing right angle, very convenient;
2) at housing bottom fluting is set, the sunk part and the fluting of chi band are complementary, and when measuring, make chi band bottom equal with the testee surface as much as possible, reduce measuring error;
3) in the chi band exit of housing elongated slot is set, the perspective window is set on elongated slot, on the perspective window lens can be set, make things convenient for reading, generally will have an X-rayed window and be opened in the chi band top that disconnected footage number one side is set;
4) the chi band is made up of two parts up and down, and top is the footage number that breaks, and the bottom is continuous footage number; The continuous footage number of bottom is the same with normal tape measure, starts from scratch, and break footage number and housing bottom and the elongated slot incompatible realization reading that matches; The threshold value of disconnected footage number for the length at the right angle, left end starting point to housing footing right side of contrast footage number with, like this when measuring, when measuring the size that needs; The directly footing place setting-out at the right angle of housing has made things convenient for reading, has also made things convenient for setting-out;
5) on housing bottom and elongated slot, also be provided with scale mark, place, housing bottom right angle is 0 scale mark, increases successively left, is convenient for measuring.

Embodiment
Below in conjunction with Figure of description the utility model is further specified:
The calibration steel tape comprises housing 1, locking key 3, rotating drum 2, wheel foot 13 and chi band 4, and chi band 4 and rotating drum 2, wheel foot 13, locking key 3 interoperations are realized chi band 4 turnover housings 1; Housing 1 footing right side is set to the right angle, and wheel foot 13 is arranged on this top, right angle, guarantees that chi band 4 always goes out near the position the right angle, guarantees the depth of parallelism of itself and housing bottom; Because housing 1 footing right side is set to the right angle, when measuring, in can being convenient for measuring apart from and do not need bending chi band; Directly footing setting-out after measuring in addition along the housing right angle, very convenient, be provided with fluting 8 in housing 1 bottom centre; The width of fluting 8 is 3:5 with the ratio of chi band 4 width, is unlikely to like this when pulling chi band, and the chi band drops out from fluting; The sunk part of chi band 4 and described fluting 8 are complementary, and when measuring, make chi band 4 bottoms equal with the testee surface as much as possible; Reduce measuring error, wherein locking key 3 is identical with prior art with rotating drum 2, repeats no more at this.
During practical implementation, can elongated slot 5 be set in the chi band exit of housing 1, housing 1 all is provided with fluting 8 with the bottom of elongated slot 5, and the width of fluting 8 is 3:5 with the ratio of chi band 4 width.Chi band 4 is made up of two parts up and down, and top is the footage number 10 that breaks, and the bottom is continuous footage number 11; The continuous footage number 11 of bottom is the same with normal tape measure, and threshold value is zero, the threshold value of disconnected footage number 10 for the length at the right angle, left end starting point to housing footing right side of contrast footage number 12 and; The left end starting point that promptly contrasts footage number 12 to the length of the length of housing and housing bottom and; Like this when measuring, when measuring the size that needs, directly footing place setting-out at the right angle of housing; Make things convenient for reading, also made things convenient for setting-out; Generally speaking, the scope of disconnected footage number threshold value is 3-50cm; Above elongated slot 5, be provided with perspective window 7, perspective window 7 is provided with lens, makes things convenient for reading, and perspective window 7 is arranged on disconnected footage number 10 1 sides of chi band; In elongated slot 5, also be provided with the contrast footage number 12 that matches with chi band 4 readings, can guarantee the precision of reading, contrast footage number 12 can be a scale or many scales, is as the criterion with its high order end starting point place during reading; Below housing 1 and elongated slot 5, be provided with continuous scale mark 9, the scale mark of the rightmost side is zero, and right-to-left increases progressively successively, convenient actual measurement.
The utility model can use as tape measure separately, also can be used with other equipment.For example the described tape measure of the utility model is cooperated with cutting machine; The fixedly locating rack of tape measure is set on cutting machine; When section bar is placed on the cutting machine; Section bar one end can touch the hook of tape measure, and section bar moves pulls out the chi band of tape measure, so just can realize the tolerance of section bar yardstick very convenient.
The utility model is not limited to above embodiment, and the variation that all thought that accordings to the utility model is carried out is all within the protection domain of the utility model.
