The present embodiment is substantially the same manner as Example 5, and difference is: during in the present embodiment, the top of second spike is no longer at the open-work of the first support board.
In the present embodiment, the roof of each second spike is bonded and fixed on the diapire of the first support board, the top of each second spike is provided with annular spacing groove 636 and is positioned at the connection screw 637 of this annular spacing groove center, and this annular spacing groove and connection screw are positioned at the underface of a corresponding open-work；Each second precision weigh assembly also include supporting member 67, screw thread spring 68 and regulation screw 69；A corresponding open-work is just arranged by supporting member, and the center of supporting member is provided with adjustment hole 671, and the periphery wall of supporting member is provided with the annular stop crimping boss 672 of evagination；The bottom of spring is positioned in annular spacing groove, and is crimped on second spike, and the top apical grafting of spring is on the diapire of supporting member；Regulation screw is sequentially provided with the portion of screwing 691, slide connecting part 692 and the spiro union portion 693 adaptive with adjustment hole from top to bottom, screws the external diameter external diameter more than slide connecting part in portion, and the shape of slide connecting part is the cylinder that outer wall is smooth；The adjustment hole of supporting member is stepped hole, is the bigger less slide opening district 6712 of crimping porose area 6711 and aperture, aperture the most successively, and the diapire of crimping porose area is as electrolysis 6713, and slide opening district is the circular hole that hole wall is smooth；Described spiro union portion be spirally connected be fixed on second spike top connection screw in；During free state, under the top pressure effect of spring, spacing crimping boss exceeds the roof of the second support board, and the portion of screwing is positioned in crimping porose area, and the diapire screwing portion is crimped on the diapire of crimping porose area, namely on described electrolysis；Slide connecting part is then positioned in slide opening district；Under external force, slide connecting part can slide up and down in slide opening district, so that supporting member can move up and down under the guide effect of regulation screw slide connecting part；During supporting member pressure-bearing stress, compression spring thus driven spacing crimping boss to move down, when supporting member pressure-bearing stress is to predeterminable level, spacing crimping boss is crimped on the roof of the second support board.
The present embodiment is when using as electronic scale, it is possible to use four supporting members are as the strong point so that the first support board is above ground level, prevents from scratching the first support board；Additionally, the present embodiment is when as body weight electronic scale, by selecting the distance between suitable spring and annular stop crimping boss 672 and the first support board roof, can ensure that spring passes to the pressure maximum holding capacity not over the first precision LOAD CELLS of the first precision LOAD CELLS, prevent the first precision LOAD CELLS from will not agree and press through weight and damage.
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.
