Abstract
The utility model relates to an electric price counting platform balance. The electric price counting platform balance is characterized in that two symmetrical U-shaped first levers are arranged along the periphery of a base; the first levers bear the weight of a weight-bearing platform, and one of the first levers transfers force to the tail end which is connected with a second lever according to a definite lever ratio; than, the first lever transfers the force to the tail end which is connected with a sensor by a definite lever ratio again. The electric price counting platform balance can be made thinly (is a second of an ordinary machinery platform balance), and is only provided with a small volume sensor. Thus, the utility model has the advantages of low price, strong adaptability, light weight, high accuracy, etc.
Description
The utility model relates to the Weighing utensil that a kind of automatic numeral shows, i.e. computer valuation platform scale.
The ground flat table scale major part of existing medium weighing (1t-5t) is a mechanical scale, and its force transferring lever is * superimposed type, so this platform scale is heavy and thicker, use very inconvenient, and valuation Presentation Function automatically not.Along with development of electronic technology, the electronics measuring weighing instrument has appearred, and they all are to adopt 2 or 4 jumbo sensors, receive the pressure signal of bearing platform, so their prices are very high, again because of being directly to use sensor, environmental baseline is required comparatively harsh, often break down or be damaged.
The purpose of this utility model solves the shortcoming that the scale body that exists in the prior art is thick and heavy, price is high, use is tender with regard to the platform scale that provides a kind of machinery and electronics combination.
The purpose of this utility model is achieved in that
Be symmetrical arranged one-level lever and a second lever of pair of U-shaped along perimeter, one side of each one-level lever is provided with one and holds cutter, two and hold cutter and three and hold cutter, only establishing one on the another side holds cutter and two and holds cutter, one holds cutter and force bearing ring links and by the axle supporting on the base, two hold cutter and are associated in cutter on the bearing platform and hold and link, three hold cutter and an abutment ring links, abutment ring is associated on the coupling shaft that is fixed on the second lever, and the middle part of second lever is provided with a supporting-point, the end is provided with suspension ring and sensor links.
Owing to adopted technique scheme, its force transmission mechanism is made up of one-level lever and a second lever of two U-shapeds, with former mechanical platform scale * the superimposed type lever compares, not only lever itself attenuates, and become one deck by two layers of lever of * superimposed type, make the scale body thickness reduce more than 1/2.Stressed less because be located at the sensor of second lever end again, so can use than the sensor weighing of low capacity weight greater than its capacity hundreds of times.Therefore the utility model price lower (be all electronic scale about 25%), durability strong (because be the mechanical type load-bearing, sensor is directly load-bearing, does not have the tender property of electronic scales), the bearing platform ultrathin type, easy to use, precision can reach international three grades.
Routine accompanying drawing provides a most preferred embodiment of the present utility model down:
Fig. 1 is a vertical view of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to partial enlarged view;
Fig. 3 is that the B-B of Fig. 1 is to partial enlarged view;
Fig. 4 is the C-C cut-open view of Fig. 1.
As shown in the figure, base 100 is made a rectangular frame by channel-section steel, one crossbeam 101 is arranged in the middle of it, the U-shaped one-level lever that is provided with along perimeter is by minor face 201, base 200, long limit 202 constitutes (the one-level lever on the right and base center line symmetry, the Therefore, omited), base 200 is made by steel pipe, long, minor face is made by steel plate and is welded with the base steel pipe, long, all be provided with on the symmetric position of minor face the edge of a knife up and down one hold cutter 300, two hold cutter 400, as shown in Figure 2, two hold cutter 400 supporting and be associated in cutter on the bearing platform 500 and hold 401, one cuttves and hold 300 and hold 301 to pressing down cutter, cutter holds 301 and is associated on the force bearing ring 302, and it is born by the axle 303 that is fixed on the base.The other end on the long limit 202 of one-level lever is associated with three and holds cutter 600, as shown in Figure 3, it is pressed in the cutter that is coupled to abutment ring 602 bottoms and holds in 601, the top of abutment ring 602 also is associated with a cutter and holds 603, it is pressed on the coupling shaft 702 of the band edge of a knife, coupling shaft 702 is fixed in second lever 700 1 ends, as shown in figures 1 and 3, be provided with one on the position that takes at second lever 700 middle parts and hold cutter 705, base 101 relevant positions are associated with support 703, which is provided with a cutter and hold 704, its supporting is held cutter 705 on second lever.Second lever 700 left parts are associated with suspension ring 706, and it is enclosed within on the sensor 800, and sensor 800 is fixed on the base 101, and a protection box 801 is set.
