Description

Intelligent height measuring instrument

Technical Field

The utility model belongs to the technical field of teaching equipment, and particularly relates to an intelligent height measuring instrument.

Background

At present commonly used height measuring apparatu when measuring, all need a staff to stand by the dipperstick, surveyed people stands well the back before the dipperstick, and the staff removes the level bar to surveyed people top with the hand, then reads numerical value on the dipperstick alright obtain surveyed people's height value. Such height measuring instruments have the following problems: for group physical examination, such as annual check-up of soldiers, college entrance examination and other routine student physical examinations, collective physical examination of unit workers and the like, the staff needs to frequently move the level, the labor intensity of the staff is high, and the efficiency is low; on the other hand, different workers move the level to the top of the head of the tested person, and due to human factors, the contact tightness between the level and the head of the tested person is different, different measurement results can be obtained, and the problem of inaccurate measurement occurs. Therefore, it is necessary to develop an intelligent height measuring instrument which can measure accurately and display the measurement result visually.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an intelligent height measuring instrument.

The utility model aims to realize the purpose, the scale rod comprises a hollow scale rod, a screw rod is arranged in the hollow scale rod, the bottom of the screw rod is connected with a servo motor, a sliding block is sleeved on the screw rod and connected with a stress detection sheet, a stress sensor is arranged on the stress detection sheet, a sliding groove capable of supplying the stress detection sheet to slide up and down is formed in the scale rod, the screw rod is fixed on a reference table, and the servo motor, the stress sensor and a voice broadcast device are all electrically connected with a controller.

Compared with the prior art, the utility model has the following technical effects:

the brand-new height measuring mode does not need to use a ruler and draw scale lines, the distance can be measured through stress induction, then the distance is displayed in real time through an electronic display screen, voice broadcasting is carried out simultaneously, convenience for adults is brought, the device is more suitable for families with children, the device is more convenient to compare with a traditional ruler for measuring heights of infants and teenagers, and the change condition of the heights of the children from small to large can be counted as long as the device is recorded according to rules.

FIG. 2 is a schematic front view of the overall structure of the present invention;

FIG. 3 is an enlarged view of portion A of FIG. 2;

in the figure: 1-scale rod, 11-chute, 2-screw rod, 3-servo motor, 4-slide block, 5-stress detection sheet, 6-stress sensor, 7-electronic display screen, 8-seat board, 9-support and 10-universal wheel.

Detailed Description

The utility model is further described with reference to the accompanying drawings, but the utility model is not limited in any way, and any alterations or substitutions based on the teaching of the utility model are within the scope of the utility model.

As shown in the figure, the measuring scale comprises a measuring scale rod 1, the measuring scale rod 1 is of a hollow structure and is internally provided with a screw rod 2, the bottom of the screw rod 2 is connected with a servo motor 3, a slide block 4 is sleeved on the screw rod 2, the slide block 4 is connected with a stress detection piece 5, a stress sensor 6 is arranged on the stress detection piece 5, a chute 11 capable of supplying the force detection piece 5 to slide up and down is formed in the measuring scale rod 1, and the screw rod 2 is fixed on a reference table.

The bottom of the reference table is provided with universal wheels 10.

The base plate is provided with a seat plate 8, the seat plate 8 is fixed on the base plate through a support column 9, and the seat plate 8 is connected with the support column 9 through a hinge.

And an electronic display screen 7 is arranged on the front surface of the scale rod 1.

Scale pole 1's side on be provided with the scale mark, we can compare according to voice broadcast's data and the numerical value on the scale, when needing to carry out quality control, can compare through the numerical value of scale mark and electronic display screen's numerical value, verify whether measured data is accurate.

And a voice broadcasting device is arranged in the electronic display screen 7.

The working principle and the working process of the utility model are as follows:

the intelligent height measuring instrument provided by the utility model drives the screw rod to slide the stress detection piece up and down through the servo motor, when the stress detection piece touches the head of a measured person, the stress sensor transmits a signal to the servo motor, the motor stops acting, the electronic display records and displays the data, and the built-in voice broadcaster broadcasts the numerical value. The measuring instrument does not need to use a ruler, draw scale lines and read the reading by naked eyes. The measurement is more accurate. The pressure plate does not need to be manually and frequently removed in a sliding mode, deviation caused by vertical sliding of the traditional pressure plate is avoided, measurement is more accurate, only the motor needs to be started in measurement, and after measurement is finished, the stress detection plate automatically returns.
