In each figure, 1 is chassis, and 2 is column, and 3 is panel, and 4 is sliding stone roller, and 5 is the arm beam of steelyard, and 6 is target, and 7 is notch, and 8 is mark post, and 9 is marking peg, and 10 is knee, and 11 is needle pivot, and 12 is axis hole, and 13 is pointer, and 14 is T-slot, and 15 is words identification.

embodiment:

Below in conjunction with accompanying drawing to the design's explanation for example.

As Fig. 1, shown in Fig. 2, the common lever balance theory that utilizes carrys out the platform scale of work primarily of chassis 1, column 2, panel 3 and the arm beam of steelyard 5, sliding composition such as parts such as stone roller 4 grade, the design item of the easy reading platform scale mentioned in background technology has then set up target 6, notch 7, mark post 8, marking peg 9 associated components, the present on this basis, the right-hand member of the notch 7 on panel 3 is continued to process a T-slot 14 again, corresponding target 6 is also done same processing and is provided with semicircular low middle high words identification 15 on the right side of T-slot on target, the arm beam of steelyard 5 faced under T-slot upwards connects a warpage knee 10 once forward, as Fig. 2, Fig. 3, shown in Fig. 4, the tip portion of knee 10 the upper half protrudes upward T-slot and also wears a pointer 13, wear tail end and left end that position refers to pin, connection is worn by the perforation strengthened, the tip of pointer and right-hand member then point to the low middle high words identification 15 on right side, longitudinal microscler axis hole 12 is processed with in the centre of pointer 13, the needle pivot 11 that one top arranges die penetrate in axis hole with the target under pointer and panel affixed with the rotary middle point of positioning pointer 13 substantially.In weighing operation when sliding stone roller 4 horizontally slips the horizontal equilibrium point finding the arm beam of steelyard on the arm beam of steelyard 5, what the arm beam of steelyard 5 was inevitable will swing up and down certain pitch angle relative to horizontal (0 ° of angle), i.e. Fig. 4, Fig. 5, high, normal, basic location status shown in Fig. 6, very naturally and the knee 10 that links together of the arm beam of steelyard also can synchronous follow-up, in this upper and lower servomechanism process of knee, the tail end of the pointer 13 of its upper sleeve through is because be by the perforation connection of increasing and the Action of Gravity Field of own wt so the state that arranges that only can can't be tilted by it thereupon moving up and down drives be close on T-slot 14 do swing (die on needle pivot 11 is arranged also can produce downward tube bank effect to pointer), as Fig. 4, Fig. 5, it is exactly the demonstration of this swing effect shown in Fig. 6, corresponding drive pointer 13 rotates to an angle around needle pivot 11 and makes its needle point direction point to the words identification 15 of different low middle high positions, specifically, when the arm beam of steelyard 5 is in horizontal just, can set corresponding pointer 13 point to being designated of positive right side " in " position, location status as shown in Fig. 5 and Fig. 3, when to be in as shown in Figure 4 high-order for the arm beam of steelyard, corresponding knee 10 also culminates, the tail end of its pointer 13 driven then is in the location status that shape is forward as shown in Figure 4, and pointer needle point has then pointed to the location status of " height " as shown in the zoomed-in view in left side in Fig. 3, when the arm beam of steelyard is in low level as shown in Figure 6, corresponding knee 10 also reaches low spot, the tail end of its pointer 13 driven then is in shape rearward position state as shown in Figure 6, and pointer needle point has then pointed to the location status of " low " as shown in the zoomed-in view on right side in Fig. 3, because knee 10 its right position when swinging up and down motion does not change, if the axis hole 12 on pointer 13 is not arranged to longitudinally elongated hole but only slightly larger than the circular hole of needle pivot rugosity, pointer 13 then can be made to occur when swinging up and down motion along with knee blocking other situation, because obviously as shown in enlarged drawing in Fig. 3, when knee drives the high, normal, basic position of pointer to change, needle pivot 11 does not immobilize to the distance length of the tail end of pointer 13 but can change, microscler axis hole 12 has just eaten up part of this distance change when knee swings relative to the additional space of the rugosity of needle pivot, eliminate the other phenomenon of the card likely produced, make whole plant running rationally reliable, the instruction of high, normal, basic position is synchronous and accurate.Like this, when sliding stone roller horizontally slips the equilibrium point determining the arm beam of steelyard arm beam of steelyard high and low position will synchronous reaction on the right side of platform scale panel on pointer and low middle high words identification on, only need observe easily and just can know whether and be adjusted to equilibrium position and the high and low position of facing upward the observation arm beam of steelyard right-hand member of head without the need to bending again, the design and the cooperatively perfect optimizational function of common platform scale of front design, make the display device operated and observed reading all can no longer be bent to face upward head and only need be observed easily on platform scale panel, it is the useful improvement that this tradition of platform scale weighs utensil.
