Abstract
The utility model relates to a ruler special for convergence meters, which is composed of a ruler frame and a ruler band. The utility model is characterized in that the ruler frame is provided with an open architecture, the ruler band is made of 65 Mn steel, the thickness is 0.3 mm, the width is 12.5 mm, the hole distance is 25 mm, the pore diameter is phi 3.5 mm, and the surface is provided with a euphotic zone with chromium coating. The utility model has the advantages of free and easy ruler frame for receiving and placing the ruler band, high strength of the special ruler band and large rigidity, the tension is increased by near twice than the city-sold product, the tensile deformation is smaller by over 30 percents, the anti bending performance is increased greatly, and the reading of the euphotic zone in a tunnel is conspicuous.
Description
The utility model relates to a kind of measuring instrument accessory, and definitely saying so relates in the underground works, measures the special ruler that disposes on a kind of convergence gauge of country rock deformation.
At present, the convergence gauge of domestic production all adopts the common boxlike steel tape of selling with cloth to make the measurement chi tool of accessory, and its GB parameter is the thick 0.18-0.2mm in cross section, wide 10-12mm, and pitch-row 25mm, there is following shortcoming in aperture φ 3mm as the convergence gauge special ruler:
1, the steel tape belt tension is little, its cross section parameter and material all are difficult to satisfy the requirement that convergence gauge perforate chi band loads hightension, Yi Huokong, easily bending, and the chi band is analysed the curved change that all can cause actual measurement length a little, and is inapplicable as this chi band of accurate measurement.
Easy slide calliper rule when 2, the boxlike chi frame of common boxlike steel tape is put chi, and its rocking handle common design is too small, grabs by very inconvenient, footage is also required great effort.
3, commercially available boxlike steel tape is black-tape, and is not eye-catching in the road, unfavorable to measuring.
The purpose of this utility model is: for the user provides a kind of accurate measuring convergence gauge special ruler of underground works that is suitable for, its chi band strength height, rigidity is big, the warping resistance performance is good, can satisfy the requirement that hightension loaded and hanged down tensile deformation under the perforate condition, and chi belt surface light reading in the tunnel is eye-catching, and the special ruler frame of design can make the folding and unfolding of chi band free and relaxed.
The purpose of this utility model is achieved by the following technical solution:
A kind of convergence gauge special ruler, comprise by chi frame and dress rocking handle thereon, the perforate chi band assembly that is contained in the chi frame constitutes, it is characterized in that: the chi frame adopts long rocking handle, Open architecture, it is that 0.3mm, width are 12.5mm that the chi band is then made thickness with the 65Mn steel, pitch-row is 25mm, and the aperture is φ 3.5mm, and the surface has the special ruler band of chrome plating.
Advantage of the present utility model is: because the chi frame is an Open architecture, can not produce card shows completely and resembles, folding and unfolding chi band is very free and relaxed, and the special ruler band has the intensity height, characteristics such as rigidity is big, its chi belt tension has improved nearly twice than the commercially available prod, under equal tension force condition, test also shows, self tensile deformation amount of this chi band is littler more than 30% than commercially available ordinary steel tape measure, satisfied that hightension under the perforate condition loads and the requirement of low stretcher strain, and the warping resistance performance is greatly improved, chi band light is convenient to make things convenient for reading in the tunnel.
The utility model has following accompanying drawing:
Fig. 1 is the convergence gauge special ruler composition of signing an undertaking.
Mark among the figure: 1 is the chi frame, and 2 is the chi band, and 3 is rocking handle, and 4 is chi end connector, and 5 is chi frame one lever web member.
Embodiment: chi frame shape and structure: have long rocking handle, Open architecture, the long 135mm of frame, chi band 65Mn steel is made, belt surface has chrome plating, bandwidth 12.5mm, thick 0.3mm, pitch-row 25mm, aperture φ 3.5mm, this chi tool can pass through chi frame one lever web member, and the chi tool is contained in convergence gauge lever below, can also be by chi end connector, as grab cassette measuring point connector, measuring point up and down uses more convenient quickly and easily.
Claims (1)
1, a kind of convergence gauge special ruler, the perforate chi band assembly that includes the chi frame, is contained in the chi frame constitutes, it is characterized in that: the chi frame adopts Open architecture, it is 0.3mm that the chi band is made thickness by the 65Mn steel, width is 12.5mm, pitch-row is 25mm, and the aperture is φ 3.5mm, and the surface has the bright steel band of the high strength of chrome plating, big rigidity, high warping resistance.
