Abstract

The utility model which discloses an electronic price balance consists of a lower shell body (7), an upper shell body (3), a weight bearing stent (4), earthquake-resistant pads (1), weight bearing discs (2), a circuit control part and an electronic display part, and the upper shell body (3) is fixedly connected with the lower shell body (7), and the earthquake-resistant pads (1) are arranged at the four corners of the weight bearing stent (4), and the weight bearing discs (2) are put on the earthquake-resistant pads (1), and the lower shell body (7) is provided with a quad (18), and one end of a weigh sensor (5) is fixedly connected with the quad (18) on the lower shell body (7) while the other end of the weight sensor (5) is connected with the weight bearing stent (4); support legs which are arranged at the four corners of the lower shell body (7) is provided with a locking nut (8); a horizontal bulb (17) is arranged at the lower shell body (7); a stiffener (19) on the lower shell body (7) is arranged in the shell body. By adopting the structure of the utility model, the weight bearing stent can be saved, and the production, assembly and debug can be easier, and the utility model has the advantages of simple and reasonable structure, low cost, convenient horizontal regulation and correct weighing.

Description

Electronic price computing scale

One, technical field

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.

Two, background technology

The electronic price computing scale that uses generally all is that weighing sensor is fixed on the following support bracket of lower house at present, and weighing sensor is fixedlyed connected with following support bracket again, and last support bracket is fixedlyed connected with LOAD CELLS, and places crash roll and load-bearing plate thereon.Because support bracket under being fixed with on lower house, this certainly will increase the weight and the installation difficulty of loom, has also improved production cost.The horizontal adjustment difficulty influences the accuracy of weighing besides.

Three, summary of the invention

For overcoming the difficult problem of above-mentioned existence, problem to be solved in the utility model provide a kind of simple and reasonable, install produce easily, cost is low, horizontal adjustment electronic price computing scale easily.The technical solution adopted in the utility model is, it comprises lower house, upper shell, support bracket, crash roll, load-bearing plate, and circuit control section and electronics display part, upper shell is fixedlyed connected with lower house, crash roll is arranged on four jiaos of support bracket, and load-bearing plate is placed on the crash roll, and lower house is provided with abaculus, LOAD CELLS one end is fixedlyed connected with the abaculus on the lower house, and the other end is connected with support bracket; Lower house is provided with support foot for four jiaos, and set nut is set on the support foot; Lower house is provided with spirit bubble, and the reinforcement on the lower house is arranged on the inside of housing.After adopting said structure, can save down support bracket, production, installation, debugging are more prone to, and have advantages such as simple and reasonable, that cost is low, horizontal adjustment is convenient, weighing is accurate.

Fig. 3 is second kind of structural representation of the utility model.

Fig. 4 is the B-B diagrammatic cross-section of second kind of structure of the utility model.

Five, embodiment

Illustrated in figures 1 and 2, specific embodiments for first kind of electronic price computing scale of the utility model, it comprises lower house 7, upper shell 3, support bracket 4, crash roll 1, load-bearing plate 2, and circuit control section and electronics display part, the circuit control section is by accumulator box 11, transformer 14, supply socket 12, fuse 13, power switch 15 is formed, the electronics display part is made up of display screen 10 and circuit board 20, upper shell 3 is fixedlyed connected with lower house 7, crash roll 1 is arranged on four jiaos of support bracket 4, load-bearing plate 2 is placed on the crash roll 1, lower house 7 is provided with abaculus 18, LOAD CELLS 5 one ends are fixedlyed connected with the abaculus 18 on the lower house 7, and the other end is connected with support bracket 4.Lower house is provided with support foot 9 for 7 four jiaos, and set nut 8 is set on the support foot 9, and support foot 9 is installed on the mounting hole 16; For horizontal adjustment, on lower house 7, be provided with spirit bubble 17; In order to increase the physical strength of lower house, lower house 7 is provided with reinforcement 19, and reinforcement 19 is arranged on the inside of housing.

Fig. 3 and shown in Figure 4, specific embodiments for second kind of electronic price computing scale of the utility model, the reinforcement 19 that different is on the lower house 7 is arranged on the bottom of housing, the position difference that accumulator box 11 transformers 14 are provided with, other and first kind of embodiment are basic identical, at this repeated description no longer.

During weighing, article are placed on the load-bearing plate 2, gravity acts on the LOAD CELLS 5 through load-bearing plate 2, support bracket 4, make LOAD CELLS 5 produce deformation, the resistance in the LOAD CELLS 5 changes, and produces electric signal output by bridge circuit, this signal is delivered to circuit board 10, through circuit amplification, A/D conversion, CPU computing, output signal shows weight and prices to display screen 20, thereby reaches the purpose of weighing.
