Abstract

The utility model relates to a mobile electronic balance, comprising a balance seat, a balance rack, a weight sensor, a display control, etc. The bottom of the weight sensor (10) is arranged on a movable vehicle-body seat (9); the balance rack (13) is vertically fixed on the weight sensor to keep the balance rack parallel with the movable vehicle-body seat, and limit screws are vertically fixed on the balance rack; the output end of the weight sensor is connected to the input end of the display controller; the movable vehicle-body is provided with wheels which can be pushed on by a single person; a spirit bubble for testing the levelness of the vehicle-body seat is horizontally installed on the vehicle body. The utility model has the advantages of that the weighing platform can be moved freely and flexibly; a sensor protection device is provided; digital weight display, rapid, intuitive and accurate display and reliable operation are also available.

Description

The mobile electron scale

Technical field

The utility model relates to electronic scales, and particularly a kind of being used for stores in a warehouse, and the scale body arbitrarily can be moved, and can show, analyze, handle and expand the mobile electron scale of other functions to testee weight.

Technical background

The weight measurement of storage material is used comparatively general with platform scale and weighbridge in China at present.This type of is measured and claims to move comparatively difficulty, and measuring accuracy is low, and speed is slow, and then more apparent backwardness aspect data processing can't be carried out computer data and be gathered and control automatically, the requirement of incompatibility Management of Modern Physical Distribution.

Summary of the invention

The purpose of this utility model provides a kind of with the automatic acquired signal of electronic controller, automatically calculates, and shows weight with numeral, with institute's check weighing amount record go forward side by side the Xingqi he handle the electronic scales that the scale body can arbitrarily move.

Said mobile electron scale is that the electronization of platform scale commonly used, weighbridge is improved design, form by scale base, scale frame, weight sensor, display controller etc., it is characterized in that: said sensor is a kind of being installed in movably on the car body in order to obtain the weight sensor of testee weight, and the output terminal of weight sensor links to each other with the display controller input end; Said display controller can show, analyze, handle and expand the equipment of other functions to testee weight.

It is to aim at the axis of scale frame on the scale base and with sensor axis that aforesaid weight sensor is vertically fixed on the base of car body movably, and the scale frame is vertically fixed on and makes the scale frame parallel with the car body base on the weight sensor.Limited screw is vertically fixed on the scale frame, when the mobile electron scale need transport, can tighten limited screw and makes its ancient cooking vessel on scale base, thereby can protect weight sensor; Sensor is perpendicular to the ground when guaranteeing to weigh, and flatly fixes a spirit bubble on the base of car body movably, can detect the horizontality of car body base, thereby guarantee to show the accuracy of weight.

Said movably car body is that wheel is installed, the single dolly that can promote.Hydraulic pressure is housed on the dolly, the height on scalable car base and ground, more flexible thereby car body moves.

Said display controller is made up of A/D change-over circuit, input/output interface circuit, keyboard and demonstration etc., can show, analyze, handle and expand the equipment of other functions to testee weight.

By as can be known above-mentioned, the present utility model has following advantage, as:

1, weighing platform can arbitrarily move, the dirigibility height;

2, has protective device to sensor;

3, the weight numeral shows, display speed is fast, accurate, reliable operation directly perceived;

4, can expand gather, function such as printing, data transmission;

Embodiment

When object was pressed on the weight sensor, the voltage signal of weight sensor output changed, and behind the A/D change-over circuit, the A/D change-over circuit is exported the digital signal of corresponding weight of object and given single-chip microcomputer, after single-chip microcomputer is handled, testee weight is shown.If expand other functions, but growth data storer, program storage, LCD demonstration etc. reach external connection keyboard, printer, IC-card read write line etc. on the single-chip microcomputer; Single-chip microcomputer adopts 80 or 96 Series chip chips.The number of divisions of weight sensor reaches 3000.

Claims
