Detailed description of the invention

(embodiment 1, electronic scale)

The present embodiment is a kind of improved electronic scale, as shown in Fig. 1 to Fig. 4, including the first support board 1, display screen 12, Condenser type 13, four, switch of regulation has the first precision LOAD CELLS assembly 2, of a spike 21 and is provided with supporting Second precision LOAD CELLS assembly 4 of part 3 and one are for bearing pressure the second precision LOAD CELLS assembly Conduct power of the leading part 5 to the first precision LOAD CELLS assembly；First support board crimping is arranged on the first precision weighing and sensing On device assembly；Second precision LOAD CELLS assembly is arranged on below the first support board, and the bottom of a spike is this electronic scale Least significant end；First support board is provided with a supporting open-work 11, and the top of supporting member is just to supporting open-work setting mutually. Gap is left between 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 the second precision LOAD CELLS assembly 4 is as follows: include that the second precision of column is surveyed Force transducer 42, it is arranged on second precision force cell one end and exceeds the supporting boss of this second precision force cell 44, being arranged on the second precision force cell other end downwardly projecting presser feet 43, the bottom of presser feet is provided with supporting plate 45, Described supporting boss 44 is provided with male threaded joint 441 as described supporting member 3, the periphery wall on this supporting boss top.

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 supporting plate 45, 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 supporting plate 45 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 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 It is provided only with a pillar on the diapire of support board, is provided with the external screw thread with supporting boss top at this pillar bottom center and is connected The inner bolt hole of portion 441 adaptation, this pillar is spirally connected and fixes on the bearer.The periphery wall of each pillar is with a corresponding supporting thoroughly Gap is left between the internal perisporium in hole.

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.

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.
