Abstract

The utility model discloses an electronic scale with mechanical dial display. The electronic scale with mechanical dial display comprises a scale body, a main control board, a weighing sensor and a load-carrying mechanism. The load-carrying mechanism, the weighing sensor and the main control board are connected in succession. The scale body further comprises a power supply module which is used for providing power supply voltage for a circuit. A mechanical dial used for displaying a weighing value and a motor used for controlling the mechanical dial are arranged on the scale body. The motor is connected with the main control board and the mechanical dial respectively.

Background technology

Growing along with society, the making rapid progress of science and technology, but people have a kind of consciousness of missing old times or old friends, no matter science and technology progress how, and people can cherish the memory of as a child used or contacted article.Electronic scales is to be developed by former mechanical spring balance, and old-fashioned weighing apparatus wants that with present electronic scales than the most obvious difference be in the indication of weighing, and old-fashioned electronic scales all is to use index dial, or pointer is indicated the weight of the article of weighing.Can allow like this user see whole change procedure of weighing, it is comparatively tangible that the user feels.LCDs or the LED display of now electronic scales employing, its advantage is user's convenient reading.But some user who has been accustomed to the use of mechanical scale can feel that its weight numerical value is to become out, produces the suspection to its accuracy.

Summary of the invention

For addressing the above problem, the electronic scales that the purpose of this utility model is to provide accuracy of reading, shows with mechanical index dial.

The technical scheme that the invention for solving the technical problem adopts is:

A kind of electronic scales with mechanical index dial demonstration, comprise scale body, master control board, LOAD CELLS and force mechanism, described force mechanism, LOAD CELLS are connected with master control board and are connected, described scale body also comprises for the power module that supply voltage is provided to circuit, also be provided with on the scale body for demonstration weigh numerical value mechanical index dial and be used for controlling the motor of mechanical index dial, described motor respectively with master control board be connected index dial and be connected.

The weighing-up wave that master control board receives LOAD CELLS to detect, and rotate according to the weighing-up wave drive motor also drives the mechanical index dial of system and rotates and show reading in the time of electric machine rotation.

Further, also be provided with on the described scale body for the weigh LCDs of reading of demonstration, described LCDs links to each other with master control board.The user reads when weighing numerical value easily because the reasons such as angle produce error by mechanical index dial, not only can show the numerical value of weighing accurately by LCDs is set, and satisfy modern's use habit.

Further, also be provided with key-press module on the described scale body, described key-press module links to each other with master control board.Can realize the switch of electronic scales by key-press module, also can adjust the parameter of electronic scales by key-press module.

Further, described LOAD CELLS is separately positioned on four angles of scale body.This design can increase the weighing precision of electronic scales.

Further, described mechanical index dial comprises the graduated graduation indication dish of printing and can block the occlusion part of graduation indication dish high scale that the moving graduation indication dish of described motor and graduation indication dribbling rotates.Drive the graduation indication dish in the time of electric machine rotation and rotate, the mode of blocking graduation indication dish high scale by occlusion part is indicated the numerical value of weighing, and its stability is better, and the machinery index dial does not have reading to show when shutdown, designs more fashion.

The beneficial effects of the utility model are: a kind of electronic scales with mechanical index dial demonstration that the utility model adopts, not only solved the read untrue that old-fashioned mechanical city graduation indication causes because of the wearing and tearing of machinery easily, replaced " the spring mechanical structure " of old-fashioned mechanical scale as indicating graduation, all greatly improve in accuracy and on the life-span, and can satisfy the user that custom uses mechanical scale to show, increased user's experience sense.
