Detailed description of the invention

(embodiment 1, electronic scale)

The present embodiment is a kind of electronic scale, as shown in Fig. 1 to Fig. 4, including the first support board 1, display screen 12, electric capacity Formula 13, four, switch of regulation has the first precision LOAD CELLS assembly 2, four of a spike 21 and is provided with supporting member 3 The second precision LOAD CELLS assembly 4 and four for the second precision LOAD CELLS assembly is born pressure conduction Power of leading part 5 to the first precision LOAD CELLS assembly；First support board crimping is arranged on the first precision LOAD CELLS group On part；Second precision LOAD CELLS assembly is arranged on below the first support board, the bottom of spike be this electronic scale Low side；First support board is provided with four supporting open-works 11, and a corresponding supporting open-work is just arranged by the top of each supporting member. Gap is left between each supporting member and the first support board.

In the present embodiment, the concrete structure of each first precision LOAD CELLS assembly 2 is as follows: include being provided with storage tank 22 Insulating base 23, the first precision force cell 24 being arranged in insulating base, cover storage tank opening and tool There are the spring lid 25 of centre bore, the support column 26 being arranged in spring lid centre bore, stick to the spring washer 27 of support column bottom； Each support column and corresponding spring washer combination form described spike 21.The inwall of insulating base 23 roof is provided with draw-in groove, First precision force cell 24 is fixed in this draw-in groove.The top of insulating base 23 is directly bonded and fixed at first On support board diapire.

In the present embodiment, the concrete structure of each second precision LOAD CELLS assembly 4 is as follows: include insulation clamping seat 41, card The the second precision force cell 42 being located in deck, the presser feet 43 being fixedly installed on the second precision force cell 42, Crimping is fixedly installed on the supporting member 3 on insulation clamping seat 41 top, and the center, top of described supporting member is provided with limited impression 31.In the present embodiment, described each second precision force cell 42 is provided with two open-works, and the top of presser feet 43 is provided with Two riveting boss, each riveting boss riveting is fixed in a corresponding open-work, thus this presser feet is fixedly installed on second On precision force cell.

In the present embodiment, leading power part 5 is the accommodation seat 6 with diapire 61 and sidewall 62, the second precision LOAD CELLS Assembly is arranged on the diapire of this accommodation seat by the crimping of its presser feet 43, and the sidewall top of accommodation seat is bonded and fixed at first On support board diapire.It leads power principle: the second precision LOAD CELLS assembly self is born by its presser feet 43 Pressure transmission, to the diapire of accommodation seat, is then transferred on the first support board by the sidewall of accommodation seat, then by the first load Thing plate passes to the first precision LOAD CELLS assembly.In concrete practice, use other shapes of supporting member 3 instead, be also Feasible.

In the present embodiment, the first precision force cell 24 selects wide range, the body weight sensor of low precision, its range Being 0 kilogram to 180 kilograms, precision (also referred to as scale division value) is 100 grams；Second precision force cell 42 is selected little Range, high-precision LOAD CELLS for kitchen use, its range is 0 to 20 kilogram, and precision (also referred to as scale division value) is 1 Gram.

The present embodiment in use, can use separately as body weight electronic scale；Also can with external second support board with the use of, Second support board crimping is arranged on the bearer, can weigh little article with this second support board, thus as kitchen electronics Scale.

(embodiment 2, double precision electronic scale)

Present embodiment discloses a kind of double precision electronic scale using above-described embodiment 1 to make, as shown in Fig. 5 to Fig. 8, It is with the difference of embodiment 1: also include the second support board 8；Second support board be higher than the first support board, second The diapire of support board is provided with downwardly projecting four pillar 81, and each pillar is crimped on phase after a corresponding supporting open-work Answer on a supporting member；Specifically, during the bottom of described each pillar is positioned at a corresponding limited impression 31.Each pillar Periphery wall and corresponding one supporting open-work internal perisporium between leave gap, also stay between each supporting member and the first support board There is gap.

The present embodiment in use, when needs weigh little article, is just placed on the second support board weighing, when needs claim During amount human body weight, just allow people stand on the first support board and weigh；So the present embodiment can be used as body weight electronic scale, also Can be as electronic scale.

In the present embodiment, the second support board in use, can directly shelve crimping on the bearer, when without using the During two support boards, also can be taken off and separately be put, it is to avoid it is hindered the normal use of the first support board.

(embodiment 3, double precision electronic scale)

The present embodiment is substantially the same manner as Example 2, and difference is: as shown in Fig. 9 and Figure 10, and each pillar 81 is not The most directly it is crimped on a corresponding supporting member, between diapire and the supporting member of each pillar, leaves gap；The present embodiment includes The back-moving spring 82 being set on each pillar, the upper end apical grafting of each back-moving spring on the diapire of the second support board, lower side pressure It is connected on a corresponding supporting member；This structure has the advantage that by selecting proper height and the reset of coefficient of elasticity Spring, so that when the second support board bears after pressure exceedes preset value, and the second support board overcomes the elastic force of back-moving spring, Directly being crimped on the first support board, this structure effectively prevents due to the second support board load excessive damage electronic scale.

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.
