Abstract
The utility model belongs to a device for surveying, mapping and metering of lengths which applies the technology of capacitance grating to a digital display standard ruler. A fixed grating is arranged on a base-ruler. A slide ruler is installed on the fixed grating and the base-ruler. The slide ruler is composed of a movable grating digital display assembly, a fiducial matching plate and a supporting frame. When the utility model is used, an aligning line is aligned with the initiation point for measurement, a zero adjustment press button on the movable grating digital display assembly is pressed. When the aligning line is moved to the terminal point for measurement, a liquid-crystal display plate can correctly display the displacement reading of the measurement. The utility model is in accordance with the HB8004-91 standard of China, the length of the measurement can reach 1000 mm, the resolution can achieve 0.01 mm, and has the advantages of quick operation and convenient operation.
Description
The utility model belongs to a kind of length mapping and gauging instrument.
In the prior art, what length mapping and gauging instrument were the most frequently used is the metal lines chi, the disadvantage reading mode of this class standard chi is read for estimating with magnifier, differentiate rate variance, though occurred digimatic calipers modern age, but the measurement range of these class slide calliper rule is less, and the general measure scope is only limited to measuring workpieces and can not be used for mapping and metering all less than 500mm.Also do not see the digital display standard metre bar that measurement range can reach 1000mm.
The purpose of this utility model provides a kind of third-class standard metre bar of digital display that meets the HB8004-91 standard of State General Bureau of Surveying Cartography's promulgation.
Embodiment of the present utility model is that the appearance gate technique is applied on the digital display standard metre bar, on basic chi, be equipped with and measure the fixed grid that length conforms to, installing one on this fixed grid and basic chi can be by surveying and drawing the slide rule that direction be done parallel displacement, this slide rule is made up of line plate and moving grid digital display assembly support, benchmark, chute coupling on the footing of this support and the basic chi makes the slide rule that whole moving grid digital display assembly is housed do parallel displacement on basic chi and fixed grid.
The utility model has the advantages that: a kind of third-class standard metre bar of digital display that meets the HB8004-91 standard of State General Bureau of Surveying Cartography's promulgation is provided, mapping length can reach 1000mm, be longer than existing digimatic calipers greatly, resolution can reach 0.01mm, no longer needing to use magnifier to estimate reads, mobile slide rule will show reading automatically, and it is convenient rapidly to use.
The utility model description of drawings is as follows:
Accompanying drawing 1 is the structural drawing of the utility model embodiment.
Accompanying drawing 2 is the fixed grid structure principle chart.
Accompanying drawing 3 is a moving grid digital display modular construction schematic block diagram.
Drawing is described as follows:
The 1-fixed grid, 2-base chi, the 3-moving grid, the 4-LCD panel, the 5-slide rule, the 6-surface-mounted integrated circuit, 7-zero setting button, 8-fine motion adjusting screw, the fastening slide block of 9-, 10-benchmark are to the line plate, and 11-support, 12-hold grid reflection pole plate, and 13-holds grid ground connection pole plate.
Embodiment:
Accompanying drawing 1 is the structural drawing of the utility model embodiment.On basic chi 2, be equipped with and measure the fixed grid 1 that length range conforms to, a slide rule 5 is installed on basic chi 2, slide rule 5 is by support 11, benchmark is formed line plate 10 and moving grid digital display assembly, the chute coupling of the footing of support 11 and basic chi 2 both sides is installed a fastening slide block 9 and a fine motion adjusting screw 8 for the ease of using the parallel interlock with slide rule of adjusting.Accompanying drawing 2 is the structure principle chart of fixed grid, and fixed grid 1 is made up of the appearance grid reflection pole plate 12 and the ground connection pole plate 13 of series of parallel.Moving grid digital display assembly is made up of moving grid 3, LCD panel 4, surface-mounted integrated circuit 6 and zero setting button 7, its structural principle as shown in Figure 3, moving grid 3 is made of emitting electrode and receiving electrode, and surface-mounted integrated circuit 6 comprises oscillatory circuit, receiving circuit, operational amplification circuit and output circuit.Moving grid digital display assembly also can be selected the HT-91997 standard component for use.The third-class standard metre bar of this capacitive grid numeral display, during use with benchmark to the alignment line on the line plate 5 to the locating tab assembly starting point, then zero setting button 7 is pressed in zero-bit, when moving to whole slide rule 5 to the locating tab assembly terminal point, LCD panel 4 will correctly demonstrate the displacement readings of measurement.
Claims (3)
1, the third-class standard metre bar of a kind of capacitive grid numeral display, it is characterized in that: it is to be equipped with on a foundation chi and to measure the fixed grid that length conforms to, on this fixed grid and basic chi, the slide rule that can do parallel displacement by the mapping direction is installed, this slide rule is made up of line plate and moving grid digital display assembly support, benchmark, the chute coupling of the support footing of slide rule and basic chi both sides.
