Abstract
The utility model relates to a portable electronic scale with digital display, comprising a handle, a scale body, a scale hook, and a digital display device. The utility model is characterized in that a capacitance and gating displacement sensor is adopted; the variation of the position and the shape of the spring is linked into the displacement variation of movbale gatings; signals outputted by a capacitance and gating circuit is processed by a CMOS chip for digitally displaying. The utility model can replace steelyards rejected by nation definitely. The utility model has the advantages of low production cost, large weighing range, and high weighing precision. The utility model is suitable to be holden by hands for explicit weighing.
Description
The utility model belongs to meausring apparatus, is specifically related to a kind of portable digital-display electronic weigher.
The steelyard that the existing market circulation is used, because degree of expressing is poor, it is inaccurate to decide star, often for illegal businessman provides fraudulent chance, State Bureau of Technical Supervision has determined to be eliminated, progressively stops to produce and using.The present alternative weighing-appliance of releasing is platform balance for example, is applicable to stationary applica-tions, and volume is bigger, and inconvenience portably uses.Still there is not at present the portable steelyard that country's typing is promoted.In the electronic scales technology,, adopt A/D converter as " pocket-size electronic scale " technical scheme of No. 2096050 patent disclosures, on the high side, " the multi-functional practical scale of miniature calculation and valuation timing " technical scheme of CN2071331 patent disclosure, structure is comparatively numerous and jumbled, and practicality is restricted.
The purpose of this utility model is to provide a kind of delicate structure, and degree of expressing is good, and weighing range is big, the portable electronic digital display scale of accurate measurement.
The utility model is taked following technical scheme.
Portable digital-display electronic weigher, include handle, scale body, steelyard hook, digital display device, the arm beam of steelyard links with cantilever and distortion spring, measuring system adopts capacitive displacement transducer, its moving grid to be arranged on the arm beam of steelyard that connects steelyard hook, the displacement that matches of the moving grid fixed grid interior with being fixedly installed on the scale body, displacement signal reaches digital display device through the cmos data process chip, realized the conversion of weight and displacement, digital display device adopts liquid crystal display, and the CMOS chip adopts E78112B.
The utility model exquisiteness simple in structure, range of weighing is big, data handling system can realize 1: 1,1: 2,1: 4,1: 10 data presentation, measuring accuracy can reach weigh ± 0.5% have tangible practical function.
Below be description of drawings of the present utility model:
Fig. 1 is portable digital-display electronic weigher master TV structure figure;
Fig. 2 looks cut-open view for the portable digital-display electronic weigher right side.
Among the figure, 1 is zero clearing, peeling (unhairing is heavy), locking control knob, and 2 is the steelyard handle, and 3 are control zero clearing locking lead, 4 is the scale body, and 5 is power switch, and 6 is the digital display liquid crystal display, 7 is the number lock button, and 8 are zero clearing, peeling, unlock button, and 9 is moving grid, 10 is the arm beam of steelyard, and 11 is chain sling, and 12 is steelyard hook, 13 is nut, and 14 for adjusting screw, and 15 are the distortion spring, 16 is the fixed grid assembly, and 17 is screw, and 12 is button cell.
Moving grid plate 9 is installed on the arm beam of steelyard 10, and one end and steelyard hook 12 link, and the other end links by cantilever and distortion spring 15.The morpheme of distortion spring changes interlock and is the change in displacement of moving grid plate 9 with the fixed grid assembly 16 of fixed in position, the signal that holds the output of grid circuit reaches digital display liquid crystal display 6 through the CMOS-E72112B processing, carries out zero clearing, peeling (Zhi Maochong), locking by zero clearing, peeling, locking press button.Carry out release by zero clearing, peeling (Zhi Maochong), unlock button 8.Circuit adopts button cell 18, little power consumption, and failure rate is low.The structure member size changes slightly, and circuit still can guarantee bigger weighing range.
Claims (2)
1, portable digital-display electronic weigher, include handle, scale body, steelyard hook, digital display device, the arm beam of steelyard links with cantilever and distortion spring, of the present utility model being characterised in that, measuring system adopts capacitive displacement transducer, its moving grid is arranged on the arm beam of steelyard that connects steelyard hook, the displacement that matches of the moving grid fixed grid interior with being fixedly installed on the scale body, and displacement signal reaches digital display device through the cmos data process chip.
2, portable digital-display electronic weigher as claimed in claim 1 is characterized in that said data processing chip is E78112B.
