Description
Technical field
This utility model belongs to measurement instrument field, is specifically related to a kind of digital display flatness verifying concrete test die and the most satisfied requirement of other body surface flatness and measures chi.
Background technology
It is to complete with edge of a knife chi, clearance gauge that the most conventional concrete test die and other body surface flatness measure.This assay method be by edge of a knife chi centered by die trial side and locating surface diagonal intersection point, measure the maximum gap i.e. surface smoothness in plane with clearance gauge.The accuracy of this measurement result and comfort level are easily affected with surface irregularity structure by testee shape, and need debugging to be repeated several times with clearance gauge and can determine its flatness.As a example by surveying (150*150*150) mm concrete test die flatness, when surveying its locating surface flatness, clearance gauge bending can need to be tested；And if survey (100*100*100) mm concrete test die locating surface flatness, then detection can be made to become to be difficult to due to diminishing of space；Or measured surface certain leaves gap, but gap width is narrower than clearance gauge width, then be that not measure it defective in this way.Therefore a kind of mensuration chi that can accurately read flatness is designed particularly necessary.
Summary of the invention
This utility model is in order to enable Accurate Determining concrete test die and other body surface flatness, and is not affected with surface irregularity structure by testee shape, uses simpler, quick, and then provides a kind of digital display flatness mensuration chi.
This utility model adopts the following technical scheme that
A kind of digital display flatness measures chi, and including blade, the lower end of described blade is provided with chi sword, and upper end is provided with slipmat, and the positive Middle face of blade has sliding tray, is provided with sliding handle in sliding tray, and sliding handle connects displacement transducer；The middle and lower part, the back side of blade is provided with draw-in groove, and the bottom of displacement transducer is placed in draw-in groove, and the top of displacement transducer is connected with blade by fixing.
Described displacement transducer includes measuring staff, and connecting bottom measuring staff has rolling ball, rolls ball and is placed in draw-in groove, and measuring staff top is provided with the connector being connected with blade.
Described measuring staff is the scalable determinator of built-in spring.
The front of described blade is provided with on & off switch and reset key, and the side of blade is provided with display screen connectivity port and charging port.
This utility model has the advantages that
1, compared with existing check meter tool, the present invention can accurately measure the flatness of measured surface any point, as long as the place that can put down blade just can measure its flatness, not by testee shape and spacial influence, range of application is more extensive；
2, this utility model is in use, slowly moves sliding handle, can the corresponding flatness numerical value of reality in the display, operate simple, quick and easy；
3, this utility model is that the displacement transducer by stretching structure measures flatness, and reading has seriality, and measured value is more accurate.

Detailed description of the invention
In conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
Digital display flatness as shown in Figure 1, 2, 3 measures chi, and including blade 3, the lower end of described blade 3 is provided with chi sword 6, upper end is provided with slipmat 4, the positive Middle face of blade 3 has sliding tray 5, is provided with sliding handle 72 in sliding tray 5, and sliding handle 72 connects displacement transducer 9；The middle and lower part, the back side of blade 3 is provided with draw-in groove 8, and the bottom of displacement transducer 9 is placed in draw-in groove 8, and the top of displacement transducer 9 is connected with blade 3 by fixing 71.
Described displacement transducer 9 as shown in Figure 4, including measuring staff 91, connects bottom measuring staff 91 and has rolling ball 92, roll ball 92 and be placed in draw-in groove 8, and measuring staff 91 top is provided with the connector 93 being connected with blade 3.Displacement sensor is fixed on blade by fixing, can move with rolling ball simultaneously, roll when ball can make displacement transducer move and reduce the frictional force with measured surface in groove.Described measuring staff is the scalable determinator of built-in spring.
Blade 3 side is provided with display connection port 10, is set to charging port 11 below display connection port, can Real Time Observation measured value by display screen.
During use, first slipmat is held, chi sword is placed in the relevant position of measured surface, display screen is connected with blade, press on & off switch, adjust sliding handle simultaneously and make displacement transducer be positioned at mensuration chi left end, check whether the rolling ball of displacement transducer, chi sword contact with measured surface, after contact to be determined, display makes zero.Slowly mobile sliding handle, shows in display that numerical value is measured surface flatness at this.
The flatness of measured surface any point can accurately be measured by mensuration chi described in the utility model, as long as the place that can put down blade just can measure its flatness, not by testee shape and spacial influence, operates simple, quick and easy.
