Abstract
The utility model relates to a multi-functional steel tape for location measurement, it is applicable to various length dimension and measures and surperficial anomalous internal diameter and inner chamber size measurement. The utility model is provided with a scale mouth with a value indicating line; one end of the ruler box is provided with a reference surface parallel to the indicating line; a standard dimension line and a positioning dimension line are carved on the surface of one side of the ruler strip; the reading of the starting point of the positioning dimension line is the distance between the indicating value line and the reference surface; the portable chain connected with the ruler box is provided with a caliper gauge. The utility model has the advantages of simple structure, convenient and accurate reading, multiple measuring functions and small measuring error.
Description
The utility model relates to the steel tape that linear measure longimetry is used.The particularly a kind of internal diameter of surface imperfection and multi-functional location survey steel tape that inner cavity size is measured of being used for.
Steel tape of the prior art when the internal diameter that is used for surface imperfection and inner cavity size are measured, because chi box self contour structures directly influences the accuracy of measurement, causes error big, the band tape damage that is subject to overwhelm.
The purpose of this utility model is to provide a kind of multi-functional location survey steel tape, and it can measure the internal diameter or the inner cavity size of all lengths size and surface imperfection effectively, improves measurement accuracy.
The purpose of this utility model is achieved in that multi-functional location survey is made up of chi hook, chi bar, chi box, chi mouth, dimension line, positioning key, portable chain with steel tape.Chi bar (2) one side surfaces are carved with standard size line (14) and location dimension line (15), the zero reading (18) of location dimension line (15) is the distance between indicating line (5) and the reference field (6), and zero reading (18) scale mark afterwards is identical with the scale separated time mode of standard size line (14).Indicating line (5) is housed on the chi mouth (4), and chi box (3) one ends are equipped with the reference field (6) that is parallel to this indicating line (5).One end of portable chain (8) links to each other with chi box (3) upper end, and the other end is equipped with calliper (16), and two measuring staff bodies (9) of calliper (16) are connected by bearing pin (10), and measuring staff hinge point (12) connects corresponding measuring staff body (9) and measuring staff (11) respectively.The thickness of measuring staff (11) is 1 millimeter, and the termination of measuring staff (11) is provided with corresponding interior measuring point (13) and outer measuring point (17).
The utility model is because of on the chi box that steel tape only need be arranged indicating line and reference field being set, dimension line and location dimension line set up standard on the chi bar, on portable chain, dispose calliper, so whole steel tape is simple in structure, simultaneously because the zero reading of location dimension line is the distance between indicating line and the reference field, so convenient reading is accurate when irregular internal diameter of surface measurements or inner cavity size; It is many that the utility model also has a measurement function, the advantage that measuring error is little.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the structural representation of multi-functional location survey with steel tape.
Among the figure, 1, the chi hook, 2, the chi bar, 3, the chi box, 4, chi mouth, 5, indicating line, 6, reference field, 7, positioning key, 8, portable chain, 9, the measuring staff body, 10, bearing pin, 11, measuring staff, 12, the measuring staff anchor point, 13, interior measuring point, 14, standard size line, 15, the location dimension line, 16, calliper, 17, outer measuring point, 18, zero reading, 19, the measuring staff inner edge.
When Measuring Object length or external diameter, chi hook (1) in the measured object outer rim, is pulled out chi bar (2), make indicating line (5) aim at another edge of measured object, on the standard size line (14) under the indicating line (5), read the dimension figure of surveying.
When the internal diameter of Measuring Object spacing or surface imperfection and inner cavity size, chi hook (1) is withstood on measured object one end face, pressing positioning key (7) pulls out chi bar (2), reference field (6) with chi box (3) leans against on the measured object other end, unclamp positioning key (7) locking chi bar (2), on the location dimension line (15) under the indicating line (5), read the dimension figure of surveying.
When the internal diameter of testee spacing or surface imperfection and inner cavity size less than indicating line (5) during to the spacing dimension of reference field (6), during promptly less than location dimension line zero reading (18), on two tested end faces that the interior measuring point (13) or the outer measuring point (17) of the measuring staff (11) on the calliper (16) can be leaned against measured object respectively, the measured object aperture pitch that two measuring points are measured is placed on the standard size line (14) of chi bar (2) and compares and measures then, reads measurement size at last.
When measuring the non-cross-sectional length size of spheroid, cylinder, cone, adjusting bearing pin (10) and measuring staff strand company's point (12) press from both sides the tested position of Cui abreast with two measuring staffs (11) of calliper (16), make two measuring staff inner edges (19) of tested position contact calliper (16), then corresponding two measuring points are placed on the standard size line (14) of chi bar (2) and compare and measure, read the measured size reading at last.
Claims (4)
1, a kind of multi-functional location survey steel tape is made up of chi hook, chi bar, chi box, chi mouth, indicating line, positioning key, portable chain.It is characterized in that: chi bar (2) one side surfaces are carved with standard size line (14) and location dimension line (15), indicating line (5) is housed on the chi mouth, chi box (3) one ends are equipped with the reference field (6) that is parallel to this indicating line (5), one end of portable chain (8) links to each other with chi box (3) upper end, and the other end is equipped with calliper (16).
