Abstract
The utility model relates to a crack width gauge with a movable indexing plate. The crack width gauge is provided with a shell with a display screen; a penetrating drive rod is arranged inside the shell; a knob is connected to one end of the drive rod; two equal drive gears are sleeved on the drive rod; meshed racks are arranged at the upper parts of the drive gears; and the transparent indexing plate higher than the display screen is fixedly connected with the racks. The indexing plate of the crack width gauge moves left and right, so that a scale mark on the indexing plate is aligned with one end of a cracked image; and the crack width gauge is simple to operate and convenient for reading, and avoids the damage to a measurement probe.
Description
Technical field
The utility model relates to a kind of New Instrument for Crack Width, and especially a kind of index dial is New Instrument for Crack Width movably.
Background technology
At present, known New Instrument for Crack Width is comprised of main frame, measuring sonde, signal wire, two legs of measuring sonde are placed on the crack, can see the crack pattern picture that is exaggerated on the display screen of main frame, when measuring sonde makes crack pattern picture namely can read fracture width vertical with rule, but for accurate reading out data, often need to align crack pattern as the scale mark that coils at an end and quarter, this just need to adjust the position of measuring sonde by a small margin, adjustment process is not only to the measuring sonde injury, and operates wayward.
The utility model content
In order to overcome existing New Instrument for Crack Width damage measurement probe, to operate uppity deficiency, the utility model provides movably New Instrument for Crack Width of a kind of index dial, this index dial movably New Instrument for Crack Width index dial moves left and right, scale mark on index dial is alignd as an end with crack pattern, simple to operate, facilitate reading, and can be to the measuring sonde injury.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of index dial is New Instrument for Crack Width movably, comprises tooth bar, index dial, display screen, drive link, housing, transmission gear, knob; This index dial movably New Instrument for Crack Width is provided with housing with display screen, enclosure interior is provided with the drive link of perforation, drive link one end is connected with knob, on drive link, cover has two transmission gears that grade is large, transmission gear top is provided with the tooth bar of engagement, is fixedly connected with the transparent index dial that exceeds display screen on tooth bar; During use, after occurring the crack pattern picture on screen to be shown, turning knob on one side the scale mark on index dial is alignd with the crack pattern picture, can facilitate and read accurately fracture width.
The beneficial effects of the utility model are that index dial moves left and right, and the scale mark on index dial is alignd as an end with crack pattern, and is simple to operate, facilitates reading, and can be to the measuring sonde injury.
