Description

Veneer double-purpose Safty electronic scale

Technical field

The invention belongs to electronic balance structure design field, be specifically related to a kind of veneer double-purpose Safty electronic scale.

Background technology

Body weight electronic scale in the market, its structure mainly includes carrying disk, display screen, power module and weighing and sensing Device forms, and its function is mainly used in human body of weighing, and substantially when display screen ability after claiming weight of object to exceed preset value Starting to show numerical value, this preset value is usually 5 kilograms；It addition, the range of this kind of body weight electronic scale is usually 180 kilograms, Bigger, in order to reduce cost, the LOAD CELLS that precision is relatively low the most all selected by this kind of electronic scale, such as public affairs For jin is unit, its display numerical value is one decimal place, namely its levels of precision is hectogram.So it is this traditional Body weight electronic scale, on ordinary days in addition to weighing in, substantially cannot function as its use, especially cannot be used for as kitchen electronics Scale is used.If it addition, select the LOAD CELLS that precision is higher to realize weighing, can make as electronic scale again With, be no problem technically, it is contemplated that precision to be at least up to by gram or 0.1g in units of, also want range The upper limit reaches 180 kilograms, and the cost of this LOAD CELLS will be higher, at least cannot be with conditional electronic scale in price Competition.

Summary of the invention

It is an object of the invention to provide a kind of both can be as wide range, body weight electronic scale that precision is low, again can be as little The veneer double-purpose Safty electronic scale of the electronic scale that range, precision are high.

The technical scheme realizing the object of the invention is: a kind of veneer double-purpose Safty electronic scale, including support board, has the First Weighing cell module of one spike, there is the second Weighing cell module of second spike and in external force The elastic supporting piece highly changed under effect；The bottom of second spike is less than the bottom of first spike；Second claims Weight sensor module include insulation shell, the mounting groove being arranged in insulation shell, be arranged in each mounting groove second survey Force transducer, cover each mounting groove opening and have central bore elastomeric cap, be arranged on elastomeric cap central bore Dagger, rotation are arranged described in roller on the support columns, crimp, each support column and corresponding roller combination formation Second spike；Elastic supporting piece includes elastically supported plate, and this elastically supported plate includes being bonded and fixed on support board diapire Fixed part and the elastic of downward-sloping extension, the lower end of elastic is turned by crimp and the second Weighing cell module Dynamic connected；When the weight of the object to be claimed on support board is less than or equal to the maximum rated weighing value of the second Weighing cell module Time, the bottom of first spike is less than the bottom of second spike；When the weight of the object to be claimed on support board is more than second During the maximum rated weighing value of Weighing cell module, elastic supporting piece forced compression entirety shortens, the end of second spike The bottom of end and first spike is generally aligned in the same plane.

In technique scheme, the whole height of elastic supporting piece changes within the scope of its elastic deformation.

The present invention both can be as wide range, body weight electronic scale that precision is low, again can be as small-range, kitchen that precision is high Room electronic scale.Even if it addition, the weight of object to be claimed is more than the maximum rated weighing value of the second Weighing cell module, only Want its weight maximum rated weighing value less than the first Weighing cell module, the second LOAD CELLS mould would not be damaged Block.

Detailed description of the invention

(embodiment 1)

The present embodiment is a kind of veneer double-purpose Safty electronic scale, as shown in Fig. 1 to Fig. 5, including support board 1, display Screen 11, regulation switch 12, power supply module 13, four have first spike 2 the first Weighing cell module 3, Four second Weighing cell modules 5 with second spike 4 and the most highly change four Individual elastic supporting piece 6.

In the present embodiment, the first Weighing cell module 3 is directly anchored on support board diapire, and the end of second spike End is higher than the bottom of first spike.

In the present embodiment, the concrete structure of the first Weighing cell module is as follows: includes plastic casing 71, be arranged on plastics Storage tank 72, the first force cell 73 being arranged in each storage tank in housing, cover each storage tank opening and There is the spring lid 74 of center positioning hole 741, the pillar 75 being arranged in spring lid center positioning hole and stick to outside each pillar The pad 76 of side, the bottom of each pad is downwardly projecting in spring lid center positioning hole；Each pad and corresponding one column combination First spike described in formation.

In the present embodiment, the concrete structure of the second Weighing cell module is as follows: includes insulation shell 81, be arranged on insulation Mounting groove 82, the second force cell 83 being arranged in each mounting groove in housing, cover each mounting groove opening and The elastomeric cap 84 with central bore 841, the support column 85 being arranged on elastomeric cap central bore, rotation are arranged on support Second spike described in roller 87 on post, crimp 88, each support column and corresponding roller combination formation.

Elastic supporting piece in the present embodiment only includes elastically supported plate 65, and this elastically supported plate includes being bonded and fixed at loading Fixed part 651 on plate diapire and the elastic 652 of downward-sloping extension, the lower end of elastic is by crimp 88 and the Two Weighing cell modules are rotatedly connected.Elastic 652 deforms upon under external force, and its whole height difference becomes Change.

By selecting suitable elastically supported plate so that the weight of the object to be claimed on support board is less than or equal to second and weighs biography During the maximum rated weighing value of sensor module, namely in time claiming weight of object less than or equal to 10 kilograms, elastically supported plate to On turn an angle, but in second spike, the bottom of roller is still below the bottom of first spike；Now second support Foot individually supports electronic scale self and the total weight of object to be claimed, weighing precision now up to 1 gram, such that it is able to As electronic scale.

When the weight until title object on support board is more than the maximum rated weighing value of the second Weighing cell module, namely In time claiming weight of object more than 10 kilograms, elastically supported plate turns an angle because stress continues up, suitable by selecting When torsion spring, the bottom of second spike hereafter and the bottom of first spike can be made to be generally aligned in the same plane, namely second Prop up spike and first spike supports electronic scale self and the total weight of object to be claimed, now the first weighing and sensing jointly Device module and the second Weighing cell module all play the effect of weighing, and by the intelligence computation of circuit, can pass through display screen Demonstrate that the accurate weight of object to be claimed, precision now are 100 grams, can use as body weight electronic scale.

Even if advantage of this embodiment is that when the weight of object to be claimed is more than the maximum rated title of the second Weighing cell module Value, as long as its weight is less than the maximum rated weighing value of the first Weighing cell module, would not damage second and weigh biography Sensor module.

Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not to this The restriction of the embodiment of invention.For those of ordinary skill in the field, the most also may be used To make other changes in different forms.Here without also cannot all of embodiment be given exhaustive.And this Belong to obvious change that the connotation of the present invention extended out a bit or variation still falls within protection scope of the present invention.
