Abstract
The utility model relates to a multi-functional micro electronic scale comprising a scale body, a weighing sensor, an operational amplifier, an A / D conversion chip, a weighing switch and a display screen. The weighing sensor is connected with the operational amplifier that is connected with the A/D conversion chip; and the A / D conversion chip is connected with the display screen. A groove is arranged in the middle of the scale body; the weighing sensor is arranged in the groove; and the display screen and the weighing switch are arranged at the surface of the scale body. An L-shaped groove is arranged in the surface of the scale body at the axial direction; an L-shaped hook is arranged in the L-shaped groove; and a gap is left between the L-shaped groove and the L-shaped hook. According to the scheme, the electronic scale with the small and exquisite size can be carried conveniently. The electronic scale can be used for weighing the weight of an object; and a plastic bag can be suspended at the L-shaped hook, so that a problem of hand ache caused by directly holding the plastic bag by the hand can be solved.
Description
Technical field
The utility model relates to a kind of multifunction micro electronic scale.
Background technology
People do shopping while buying vegetables in daily life, and a lot of people like taking a spring balance or electronic scale, the weight of the article such as the dish of buying is examined, but most volume such as current spring balance and electronic scale etc. are larger, carries inconvenience; After shopping, people are carrying shopping bag with hand, and the hand that a little while will be strangled by shopping bag aches, although there is people to design the carrying handle of carrying polybag, its volume is larger, carries inconvenience, and function singleness, and few people use.
Utility model content
The shortcoming existing in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of structure small and exquisite, and not only ponderable quantity article also can be used as the multifunction micro electronic scale of polybag carrying handle.
In order to address the above problem, the utility model is by the following technical solutions: a kind of multifunction micro electronic scale, it is characterized in that, comprise and claim body, LOAD CELLS, operational amplifier, A/D conversion chip, weigh switch and display screen, described LOAD CELLS is connected with operational amplifier, described operational amplifier and A/D conversion chip, described A/D conversion chip is connected with display screen; In the middle of described title body, be provided with groove, LOAD CELLS is arranged in described groove, and described display screen and the switch of weighing are arranged on and claim surface; Axially be provided with " L " type groove in described title surface, in described " L " type groove, be provided with " L " type hook, between described " L " type groove and " L " type hook, leave gap.
Further, be provided with LED lamp in one end of described title body, claiming that surface is provided with lamp switch.
Further, claim the right and left of body respectively arrange one described in " L " type groove.
Preferably, described operational amplifier is LM385 chip, and described A/D conversion chip is ICL7107 chip.
The beneficial effects of the utility model are: its volume is small and exquisite, easy to carry, not only can weigh the weight of article, and, its " L " type hook is upper can hanging plastic bag, solved direct use portable the hand the strangled when polybag problem of aching.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model side view;
Fig. 3 is the utility model LOAD CELLS mounting structure schematic diagram.
Embodiment
As shown in Figure 1 to Figure 3, an embodiment of the present utility model comprises title body 1, LOAD CELLS, operational amplifier, A/D conversion chip, weigh switch 2 and display screen 3, described LOAD CELLS is connected with operational amplifier, described operational amplifier and A/D conversion chip, described A/D conversion chip is connected with display screen; In the middle of described title body 1, be provided with groove 4, LOAD CELLS is arranged in described groove 4, the shape of groove 4 and the mounting means of sensor carry out difference setting according to the difference of sensor kind, for example, adopt resistance strain type sensor, as shown in Figure 3, in groove 4, be provided with two steps 401, the two ends of the sensitive beam 402 of resistance strain type sensor are separately positioned on two steps 401, the bottom surface of sensitive beam is provided with resistance strain gage 403, while weighing, the handle of polybag is placed in the sensitive beam 402 in groove 4, sensitive beam 402 produces deformation, thereby weighs; Described display screen 3 and the switch 2 of weighing are arranged on and claim body 1 surface; Described title body 1 surface is axially provided with " L " type groove 5, in described " L " type groove 5, be provided with " L " type hook 6, the bottom of " L " type hook 6 is fixedly connected with title body 1, in the time making, can, directly claiming body 1 and " L " type hook 6 to be made into integrative-structure, between described " L " type groove 5 and " L " type hook 6, leave gap.
Further, be provided with LED lamp 7 in one end of described title body 1, claiming that body 1 surface is provided with lamp switch 8.
Further, claim the right and left of body 1 respectively arrange one described in " L " type groove 5.
Preferably, described operational amplifier is LM385 chip, and described A/D conversion chip is ICL7107 chip.
Need to weigh time, open the switch 2 of weighing, the handle of polybag 9 is put in groove 4, the LOAD CELLS in groove 4 sends operational amplifier to weight signal, then through A/D conversion chip, is presented on display screen 3; After weighing completes, take off polybag 9, the handle of polybag 9, from claiming the gap between body 1 one sides " L " type groove 5 and " L " type hook 6 to pass, until " L " type is linked up with 6 bottom, when walking, is grasped and claims body 1; If in night, can press lamp switch 8 and throw light on.
The above is preferred implementation of the present utility model; for those skilled in the art; not departing under the prerequisite of the utility model principle, can also make some improvements and modifications, these improvements and modifications are also regarded as protection domain of the present utility model.
