Abstract
The utility model discloses a weighing apparatus, comprising a weight dropper and a balancing lever. The essential technical proposal is that the balancing lever adopts an automatic variable moment type, the balancing lever is provided with an angular displacement display device, the angular displacement display device is directly connected with the balancing lever, the balancing lever can be connected with a pointer or a dial or an angular displacement sensor through gears, cams, or a four-link mechanism, and the balancing lever can be made into a folding lever type or a pulling lever type. The utility model has the advantages of small size, convenient carryover, high precision, and low manufacturing cost.
Description
The utility model relates to a kind of weighing apparatus.
The weighing apparatus that uses has steelyard, counter scale or electronic scales etc. now.These several scales all have common shortcoming, promptly carry inconvenience, and the precision of counter scale is not subjected to the influence of its supporting plane, and spring balance then can reduce accuracy because of it is tired.
The purpose of this utility model provides a kind of novel weighing apparatus, and it can overcome existing shortcoming in the prior art.
The purpose of this utility model is achieved in that it comprises weight, balance stem, it is characterized in that balance stem adopts automatic torque-changing formula balance stem, is equipped with the angular displacement display device on the balance stem.
Fig. 1-the 8th is for further specifying the structural representation of five kinds of embodiment that the technical solution of the utility model proposes.
Fig. 4 is the automatic torque-changing balance stem, and it can adopt any suitable angle, is right-angle type as Fig. 1, Fig. 2 is the obtuse angle formula, and the angular displacement display device fixedly is housed on the automatic torque-changing balance stem, is pointer 1 among Fig. 1, be fixedly connected with balance stem, together swing with balance stem.Be index dial 2 among Fig. 2, index dial is fixed in an end of balance stem, swings with balance stem.Be that position, an angle claims sensor 6 among Fig. 3, what link with it has digital converter 7 and a digital indicator 8.End at the automatic torque-changing balance stem among Fig. 1 hangs alleged weight 3, and the other end is hung weight 5.Balance stem one end is hung weight 3 among Fig. 2, and weight 5 links with pointer 1, is articulated in the balance stem other end.Fig. 4 and shown in Figure 5 be the angular displacement display device with balance stem in addition two kinds connect form.Be meshed with gear 9 between balance stem and the pointer among Fig. 4.Be connected with four connecting rods 10 between balance stem among Fig. 5 and the pointer.Have cam 11 on the balance stem among Fig. 6, angular displacement be transformed into the rectilinear motion of pointer, be reduced volume, be easy to carry by cam, balance stem can be made as shown in Figure 7 the pole formula or flexible rod-type as shown in Figure 8.
The utility model has the advantages that: volume is little, and is easy to carry, and precision height and cost are low.
Claims (5)
1, a kind of weighing apparatus, it comprises weight, balance stem, it is characterized in that balance stem adopts automatic torque-changing formula balance stem, is equipped with the angular displacement display device on the balance stem.
2, weighing apparatus according to claim 1, it is characterized in that the angular displacement display device directly and balance stem link.
3, weighing apparatus according to claim 1 is characterized in that linking with gear, cam or four-bar mechanism between angular displacement display device and the balance stem.
4,, it is characterized in that the angular displacement display device can be pointer, index dial or angular displacement sensor according to claim 1 or 2 or 3 described weighing apparatus.
5, weighing apparatus according to claim 1 is characterized in that balance stem can make pole or rod-pulling type.
