In the present embodiment, being provided with containing cavity bottom opening at holding part bottom center, this opening part is provided with the capping 15 for blocking containing cavity bottom opening, is provided with center hole 151 at cap central；The bottom propping up spike extends downwardly from the center hole of capping, and leave gap between periphery wall and the inwall of cap central circular hole of a spike, thus ensure that mounting seat does not directly contact with a spike, prevent from leading power support and self pressure is directly passed to a spike by holding part, it is ensured that lead that power support passes sequentially through mounting plate portion self pressure, the second precision LOAD CELLS passes to a spike.Capping 15 with holding part with the use of, the first precision LOAD CELLS being pointed in containing cavity is preferably protected.
In the present embodiment, the range of the first precision LOAD CELLS is less than the range of the second precision LOAD CELLS, in other words the maximum of the first precision LOAD CELLS value of weighing is less than the maximum of the second precision LOAD CELLS and weighs value, by choosing suitable spring, and select suitable power of leading pressure contact portion and the distance led between power support, first precision LOAD CELLS pressure can be limited in its range ability, thus prevent the first LOAD CELLS because of overweight and by crushing；The advantage of this limiter protected mode is: owing to the elastic deformation of strain gauge load cell is the least; such as in the present embodiment, the deformation difference in height in the whole range of the first precision LOAD CELLS is calculated in microns; if using rigid support to replace the spring in the present embodiment; then the gap between power of leading pressure contact portion and power of the leading support of mounting seat of upper supporting part also must be weighed with micron; this is the most too high to requirement on machining accuracy; and the material caused in view of the error in materials processing molding and the temperature difference expands change, industrial it is difficulty with；If but use spring to amplify deformation, just can the most effectively reduce requirement on machining accuracy and manufacturing cost.
The outer wall of the present embodiment mounting seat is provided with the clamping installation portion 14 for installing self entirety, and this clamping installation portion 14 is the wedge shape latch outwardly formed from mounting seat outer wall.Base 92 is provided with four buckling grooves, and each pair of rank double precision LOAD CELLS is fixed in a corresponding buckling groove by clamping installation portion；This mounting means more simplifies, and each pair of rank double precision LOAD CELLS can independently dismount, it is simple to overhauls and changes.After four double rank double precision LOAD CELLSs are installed on base, then the top 50 of each pair of rank double precision LOAD CELLS Elastic supporting member is adhesively fixed on the diapire being arranged on support board.
The operation principle of the present embodiment is:
Upper supporting part is in free state namely when not being stressed, and the top 50 of upper supporting part exceeds the top 120 leading power support；
Move down during upper supporting part pressure-bearing stress, when upper supporting part pressure-bearing stress is less than 5 kilogram, namely time in the first rank range ability, by selecting suitable spring and selecting suitable power of leading pressure contact portion and lead the spacing of power support, during so that weigh in this rank range, the power pressure contact portion of leading will not be crimped onto and cause on support, namely upper supporting part bears whole pressure, and pass to spring, lower supporting part, the first precision LOAD CELLS, mounting plate portion, the second precision LOAD CELLS and a spike successively；Showing, now by external central control circuit, the data that the first precision LOAD CELLS measures, its accuracy value is up to 1 gram；
When upper supporting part pressure-bearing stress is less than 50 kilograms and is more than or equal to 5 kilogram; namely time in second-order range ability; the power pressure contact portion of leading can be crimped on leads on power support, owing to spring pressure is not further added by, thus effectively protects the first precision LOAD CELLS will not be because of overweight crushing；Now in upper supporting part pressure, there are 5 kilograms in concrete practice, this force value may be slightly changed because of machining accuracy error, but not over the maximum load value of the first precision LOAD CELLS, from passing to spring, lower supporting part, the first precision LOAD CELLS, mounting plate portion, the second precision LOAD CELLS and a spike successively without damaging the first precision LOAD CELLS；Remaining pressure then passes to mounting plate portion, the second precision LOAD CELLS and spike successively by leading power support；At this moment showing, by central control circuit, the data that the second precision LOAD CELLS measures, its accuracy value only has 100 grams.

In the present embodiment, the aperture of described elastomeric pad 62 central bore is more than the external diameter of the stopper section 513 of upper supporting part, thus does not affect moving up and down of upper supporting part；In concrete practice, also the aperture of elastomeric pad 62 central bore can be made the external diameter of the stopper section 513 less than upper supporting part, if but use this structure, described stopper section 513 is then to slide up and down between anticreep pressure contact portion 611 and elastomeric pad 62 roof, power of the leading pressure contact portion of upper supporting part is the most no longer to be displaced downwardly to directly be crimped on power of the leading support of mounting seat, but is displaced downwardly to be crimped on elastomeric pad.
The advantage of this kind of structure is: in concrete practice, in elastic component, the concordance of spring 52 is difficult to ensure that, typically can use four double rank double precision LOAD CELLSs due to weighing scale and kitchen scale simultaneously, the spring that concordance is difficult to ensure that will cause the height of four LOAD CELLSs slightly to be distinguished, impact assembles and uses, even when user picks up electronic scale observation, the most at grade, pole is unsightly in the bottom of each spike；The present embodiment uses governor motion to adjust the whole height of elastic supporting piece, even if so that the present embodiment uses the slightly larger spring of error, also has only to a regulation gland to be rotated in place, can ensure the concordance of whole height.Additionally, here the effect of elastomeric pad is not only and is prevented from regulating loosening of gland, the gap between whole height, or power of leading pressure contact portion and power of the leading support of mounting seat of regulation upper supporting part can also be adjusted, with the demand under satisfied different occasions by selecting the elastomeric pad of differing heights.
In the present embodiment, leading power support top and be provided with static contact 123, power of the leading pressure contact portion of upper supporting part is provided with the moving contact 514 adaptive with this static contact；When this lead power pressure contact portion be crimped on lead on power support time, moving contact crimping be arranged on static contact, both realize electrical connection.
In concrete practice, when moving contact and static contact electrical contact, produces one signal of telecommunication to connected external central control circuit, when central control circuit receives this signal, show the data that the second precision LOAD CELLS measures on a display screen；When central control circuit does not receives this signal, show the data that the first precision LOAD CELLS measures on a display screen；In other words, this dynamic/static contact combines the signal switch automatically can changed as display screen video data.
In concrete practice, also can use other structure, replace the combination of this dynamic/static contact for example with tongue tube, proximity switch etc..This kind of structure has the advantage that the real-time conversion that can realize the first precision LOAD CELLS and the second precision LOAD CELLS coherent detection data, and structure more simplifies.
Obviously, the above embodiment of the present invention is only for clearly demonstrating example of the present invention, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.And the obvious change that these connotations belonging to the present invention are extended out or variation still fall within protection scope of the present invention.
