Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the another kind of displacement deformation of measuring of the utility model is implemented illustration.
Embodiment
Of the present utility modelly to realize technological means, creation characteristic in order making, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of novel high-precision electronic surveying ruler, comprise the bracket base 1, rack beam 5, the fixation measuring head 11 that connect successively, force cell 2 is installed on described bracket base 1, bracket base 1 outside that force cell 2 is installed is provided with measures indicating meter 3, the transducing signal output terminal of force cell 2 is connected with the measuring-signal input port of measuring indicating meter 3 by wire 4, and the measuring junction of described force cell 2 is provided with the right base 6 of dynamometer spring; Described rack beam 5 is equipped with traverse measurement 9, described traverse measurement 9 smooth being enclosed within on rack beam 5 also can be moved arbitrarily, a side and testee 10 applyings near the traverse measurement of fixation measuring head 11 9, opposite side is provided with the left base 8 of dynamometer spring, between the left base 8 of dynamometer spring and the right base 6 of dynamometer spring, dynamometer spring 7 is installed.
Before the utility model uses, pack in measuring indicating meter 3 battery or directly access power supply, during measurement, mobile traverse measurement 9 is put into testee 10 between traverse measurement 9 and fixation measuring head 11, and traverse measurement 9 makes traverse measurement 9 clamp testee 10 with fixation measuring head 11 under the effect of the elastic force of dynamometer spring 7.Because testee 10 is clamped between traverse measurement head and fixation measuring head, make traverse measurement the 9 compression dynamometer spring 7 that moves to right produce elastic force, and be passed on force cell 2 by the right base 6 of dynamometer spring, force cell 2 changes elastic force into electric signal after receiving elastic force, be transferred to through wire 4 and measure indicating meter 3, show the testee size by measuring indicating meter 3.
When testee 10 sizes change, the elastic force that dynamometer spring 7 produces also will change, elastic force after change reaches force cell 2, force cell 2 changes elastic force into electric signal, be transferred to through wire 4 and measure indicating meter 3, just can accurately read size or the changing value of testee 10 like this on measurement indicating meter 3.
As shown in Figure 2, this practical another kind of embodiment is measured object deformational displacement value:
a kind of novel high-precision electronic surveying ruler, comprise T-shaped bracket base 1, rack beam 5 and bracket fixing plate 13, the vertical beam end of described T-shaped bracket base 1 is connected with rack beam 5 one ends by hinge 12, described bracket fixing plate 13 1 ends are fixed on the vertical beam of T-shaped bracket base 1 by hinge 12, bracket fixing plate 13 is provided with waist-shaped hole, the waist-shaped hole of bracket fixing plate 13 is fixed on rack beam 5 by set nut 14, force cell 2 is installed on described rack beam 5, rack beam 5 outsides that force cell 2 is installed are provided with measures indicating meter 3, the transducing signal output terminal of force cell 2 is connected with the measuring-signal input port of measuring indicating meter 3 by wire 4, the measuring junction of described force cell 2 is provided with dynamometer spring upper bed-plate 15, described rack beam 5 other ends are provided with guiding outer tube 20, be provided with guiding sliding bar 19 in described guiding outer tube 20, described guiding sliding bar 19 upper ends are provided with upper limit setting nut 21, guiding sliding bar 19 lower ends are provided with measuring head 22, described measuring head 22 is fixed on guiding sliding bar 19 by nut 17, measuring head 22 upper ends are provided with dynamometer spring lower bottom base 16, be provided with dynamometer spring 7 between measuring spring upper bed-plate 15 and measuring spring lower bottom base 16, described measuring head 22 lower ends are provided with basic point 18, and described basic point 18 is close to testee 10.
During measurement, first unclamp set nut 14, adjusting pole crossbeam 5 moves set nut 14 in the mounting hole of bracket fixing plate 13, until measuring head 22 is close on the basic point 18 of testee 10.
When deformational displacement occurs in testee 10, cause deformation and the force variation of dynamometer spring 7, and the electric signal that force cell 2 transforms also can change, the electric signal that force cell 2 produces is transferred to by wire 4 and measures indicating meter 3, measures indicating meter 3 and finally demonstrates object deformational displacement value by processing.
Above demonstration and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and instructions just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
