Abstract
The invention relates to the technical field of electronic weighing equipment, in particular to a portable electronic scale which comprises a plastic casing with a handle. Accommodating slots are formed in two sides of the casing, bolts are fixedly mounted above the accommodating slots, and the handle is provided with slide slots in which the bolts can slide. A weight sensor and a main circuit board are disposed in the casing and are connected with each other through an electric wire. A connecting rod is arranged at the bottom of the casing, one end of the connecting rod is connected with the weight sensor, and the other end of the connecting rod is connected with a hook. The portable electronic scale is reasonable in design. The handle can be accommodated in the accommodating slots through the slide slots formed in the handle, thus size of the electronic scale is reduced and the electronic scale is convenient to carry. In addition, with buttons and LED lights, the electronic scale is convenient to operate and suitable to use in dark environments.
Description
Technical field
The present invention relates to electronic weighing appliance technical field, especially a kind of Portable handheld electronic scale being widely used in light industry, electronics, chemical industry, trade and daily life.
Background technology
Electronic scales belongs to the one of weighing apparatus, utilizes the lever balance theory of Hooke's law or power to measure the instrument of mass of object.Electronics Portable electronic scale, with light, thin, short, little, is easy to carry as principal feature, is widely used in the every aspect in light industry, electronics, chemical industry, trade and daily life.Electronic portable scale is mainly by LOAD CELLS, amplifying circuit, A/D convertor circuit, single chip circuit, display circuit, the electric circuit constitutes such as keyboard circuit.Electronic scales adopts Modern Sensor Technology, electronic technology and the integrated electronic weighting equipment of computer technology, could meet and solve " fast, accurately, continuously, automatically " that in actual life, propose and weigh requirement, effectively eliminate personal error simultaneously, make it more to meet the application requirements of legal system measuring control and industrial processes control, can set up the function of electronic portable scale, make it more can meet the demand of people in live and work.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, a kind of Portable handheld electronic scale simple in structure is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Portable handheld electronic scale, have the housing that plastics are made, housing is provided with handle, and described housing dual-side is provided with accommodating groove, accommodating groove top is installed and is fixed with bolt, offers the chute sliding along bolt on handle; Described housing is built-in with weight sensor and circuit main board, between weight sensor and circuit main board, is connected by electric wire; Described housing bottom is provided with connecting rod, and connecting rod one end is connected with weight sensor, and the connecting rod other end is connected with hook.
Further, described surface of shell is provided with display screen, button and switch switch, and display screen, button and switch switch are all electrically connected with circuit main board, and display screen is provided with LED lamp around.
Further, described back side of shell is provided with power pack, and power pack is electrically connected with circuit main board.
Further, between described connecting rod and hook, be provided with abutment ring.
Further, described display screen is arranged with the translucent cover of waterproof and oilproof outward.
Measuring principle: in the time that object hangs on hook, the stressed weight sensor that is applied to of connecting rod, this weight sensor generation deformation, thus impedance is changed, use driving voltage to change, the simulating signal of a variation of output simultaneously.This signal amplifies and outputs to analog to digital converter through amplifying circuit, converts the digital signal of being convenient to process to and outputs to circuit main board, and circuit main board outputs to display screen according to button command and program by this result, until show this result.
The invention has the beneficial effects as follows: the present invention is reasonable in design, handle is provided with chute, handle can be received to accommodating groove, smaller volume, be easy to carry, be provided with button and LED lamp, easy to operate, also can be suitable at dim environment.
