Abstract

The utility model discloses an electronic measure balance comprising a base, a cover corresponding to the base, a weighing sensor, an upper support connected fixedly with the left end of the weighing sensor, damping feet arranged at four corners of the upper support, a bearing disc arranged on the damping feet, and a circuit control part and a display part, wherein a lower support is arranged on the base, the weighing sensor is arranged between the upper support and the lower support, the right end of the weighing sensor is connected fixed with the lower support, so that the bearing force of the lower support directly is applied on the support feet and will not be affected by the change of the base. The utility model has the advantages of simple structure, convenient installation, good stability and accurate measurement.

Description

Electronic price computing scale

The utility model relates to a kind of measurement instrument of weighing, the particularly a kind of electronic price computing scale that not only can weigh but also can valuate automatically.

At present the electronic price computing scale of prior art generally all is that weighing sensor is directly fixed with base, and weighing sensor is connected with upper bracket again, and placement cushions pin above the upper bracket, cushions on the step and places load-bearing plate.Because weighing sensor directly is fixed on the base, base generally adopts plastics to make, low, the poor rigidity of physical strength, and quite high to the base requirement, not only thickness is thicker, and needs to increase the reinforcement of base, and this certainly will increase base weight, has improved cost; Again since base As time goes on, temperature, environmental change meeting cause the aging distortion of plastic feet, influences the weigh transmission of power of weighing sensor, cause the weighing value to change instability, directly influence precision and accuracy that electronic price computing scale is weighed.

For overcoming the problem of above-mentioned existence, the purpose of this utility model just provides a kind of affected by environment little, the electronic price computing scale that weighing is accurate, stable.

For achieving the above object, a kind of electronic price computing scale of the present utility model, comprise base, with the corresponding cover cap of base, weighing sensor, the upper bracket of fixedlying connected with the weighing sensor left end, be arranged on four jiaos of upper brackets the buffering pin, be placed on the load-bearing plate of buffering on the pin, and circuit control section and display part, described base is provided with lower carriage, weighing sensor is arranged between upper bracket and the lower carriage, and the weighing sensor right-hand member is fixedlyed connected with lower carriage.

Described lower carriage is corresponding up and down with upper bracket.

Described base is provided with support foot for four jiaos, and set nut is set on the feet.

The utility model is because base is provided with lower carriage, and weighing sensor is arranged between upper bracket and the lower carriage, and the weighing sensor right-hand member is fixedlyed connected with lower carriage; The lower carriage bearing capacity is acted directly on the feet of base, and the influence that not changed by base has advantages such as simple in structure, easy for installation, good stability, weighing are accurate.

Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A-A cross-sectional view of the utility model Fig. 1.

Illustrated in figures 1 and 2, a kind of electronic price computing scale of the present utility model, comprise base 3, with base 3 corresponding cover caps 11, weighing sensor 6, the upper bracket 8 of fixedlying connected, the buffering pin 9 that is arranged on 8 four jiaos of upper brackets with weighing sensor 6 left ends, be placed on the load-bearing plate 10 of buffering on the pin 9, and circuit control section and display part, the circuit control section is formed, and is separately fixed on the base 1 by accumulator box 13, transformer 14 supply sockets 15, fuse 16, power switch 17; The display part is made up of display screen 12 and circuit board 18, is fixed on to constitute the front and back display panel on the base 1; Base 3 is provided with lower carriage 5 and fixing by screw 4, and weighing sensor 6 is arranged between upper bracket 8 and the lower carriage 5, and weighing sensor 6 right-hand members are fixedlyed connected with lower carriage 5 by socket head cap screw 7; Lower carriage 5 is corresponding about in the of 8 with upper bracket; Base is provided with support foot 1 for 3 four jiaos, set nut 2 is set on the feet 1, lower carriage 5 bearing capacities are acted directly on the feet 1 of base 3, can adjust the level of electronic price computing scale by regulating feet 1, with set nut 2 locking feets 1, prevent feet 1 loosening displacement.

During weighing, earlier alleged article are placed on the load-bearing plate 10, gravity acts on the LOAD CELLS 6 through load-bearing plate 10, buffering pin 9 and upper bracket 8, because the external force effect makes LOAD CELLS 6 produce deformation, resistance changes in the LOAD CELLS 6, produce electric signal output by bridge circuit, this signal is delivered to circuit board 18, through circuit amplification, A/D conversion, through the CPU computing, output signal shows weight and price to display screen, reaches the purpose of weighing from face.
