The utility model discloses simple structure, the size that can realize weight, foot is the automatic measure simultaneously, and it not only measures the accuracy, has overcome traditional artifical measuring drawback, and the measuring speed is fast moreover, can realize measuring on the device as long as the people stands.
Description
Technical field
The utility model relates to the long measurement mechanism of a kind of body weight pin.
Background technology
In solving criminal cases technical field, be very important to the information acquisition of suspect, tradition is by ruler measurement to pin measurement of length, so not only measures inaccurate, and measures and need others to help just to complete; In addition, measure pin long, also will measure body weight, waste the plenty of time.
Utility model content
For overcoming the problems referred to above, the purpose of this utility model is to provide the long measurement mechanism of a kind of body weight pin.
The utility model adopts following scheme to realize: the long measurement mechanism of a kind of body weight pin, comprise a scale, it is characterized in that: the rear side of described scale top panel is provided with the limit notch of two interval one preset distances, the left and right sides of described scale top panel is symmetrically arranged with a strip gab, described strip gab is added is provided with a baffle plate, the bottom of the support of described baffle plate is set on screw rod, and this screw rod is under the driving of a motor, movable on described strip gab in order to baffle plate; Four angles below the top panel of described scale are provided with pressure transducer, the output terminal of described pressure transducer is connected with a MCU, described MCU be connected with motor-drive circuit, display screen, for detecting Hall element and the voice broadcast circuit of motor speed.
In the utility model one embodiment, described screw rod comprises the first screw rod and the second screw rod, and the end of described first screw rod and the second screw rod is provided with a worm gear, the output shaft of described motor is arranged with the worm screw for driving described worm gear wheel.
In the utility model one embodiment, described display screen is arranged at the upper surface of described limit notch.
In the utility model one embodiment, the surface of described scale top panel is provided with sole pattern.
The utility model structure is simple, and can realize the size measurement automatically simultaneously of body weight, pin, it is not only measured accurately, overcomes the drawback that Traditional Man is measured, and measuring speed is fast, as long as people station can realize measuring on the apparatus.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figures 1 to 4, the present embodiment provides a kind of body weight pin long measurement mechanism, comprise a scale, the rear side of described scale top panel 1 is provided with the limit notch 2 of two interval one preset distances, the left and right sides of described scale top panel is symmetrically arranged with a strip gab 3, and described strip gab is added is provided with a baffle plate 4, and the bottom of the support 5 of described baffle plate is set on screw rod 6, this screw rod 6 is under the driving of a motor 11, movable on described strip gab in order to baffle plate; Four angles below the top panel of described scale are provided with pressure transducer 7, the output terminal of described pressure transducer is connected with a MCU, described MCU be connected with motor-drive circuit, display screen, for detecting Hall element and the voice broadcast circuit of motor speed.
In the utility model one embodiment, described screw rod comprises the first screw rod and the second screw rod, and the end of described first screw rod and the second screw rod is provided with a worm gear 8, the output shaft 12 of described motor 11 is arranged with the worm screw 9 for driving described worm gear wheel.
In the utility model one embodiment, described display screen 10 is arranged at the upper surface of described limit notch.
In the utility model one embodiment, the surface of described scale top panel is provided with sole pattern.Such user can know the placement direction of pin intuitively.
The utility model in use, as long as user stands on top panel, and heel aims at limit notch, then scale starts to weigh, after weighing terminates, described MCU controls electric machine rotation, motor drives bolt rotary through worm and gear, then baffle plate moves to direction of toe of last, slowing of motor detected when Hall element or stop, then illustrate that baffle plate touches toe, then MCU controls motor stopping, and by based on the number of turns of electric machine rotation, obtain the distance of baffle plate movement, the original residing distance of such baffle plate deducts the distance of movement, be exactly the length of pin, after measuring again, MCU controls motor and reverses, then baffle plate playback, the utility model arranges the long measurement function of automatic pin cleverly on scale, not only structure is simple, and can automatically measure, overcome the existing drawback needing human assistance to measure, there is good use value.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
