Description

Mechanical height and weight measuring instrument

technical field

The utility model relates to a measuring device, in particular to a height and weight measuring instrument.

Background technique

At present, the height and weight measuring instruments on the market are divided into two types: mechanical and electronic. The disadvantages of the existing mechanical measuring instruments are: 1. The person being measured cannot directly read the height reading; 2. The height value during the measurement operation It needs to be obtained by adding two parts, which is not intuitive enough; 3. If any section is not completely pulled out, the obtained height value will be inaccurate; 4. The measurement operator needs to bend down to read the data every time a height is measured; electronic The measuring instrument simplifies the operation due to the involvement of some advanced technologies such as ultrasonic measuring technology, but it is expensive and not easy to popularize and use.

Utility model content

In view of the above-mentioned shortcomings of existing mechanical and electronic height and weight measuring instruments, the applicant provides a mechanical height and weight measuring instrument with simple operation, low cost and reliable measurement.

The technical scheme adopted in the utility model is as follows:

A mechanical height and weight measuring instrument, comprising a base, a column is fixedly installed on the base, a sliding device in the column has a plurality of measuring slide bars, and the upper end of the measuring slide bar is connected to a measuring cross bar, and the feature is that: the device on the column has a body weight dial; the top of the measuring slide bar has an observation window, and the observation window includes a front window arranged on the front side of the measuring slide bar and a rear window arranged on the rear side of the slide bar; the upper end device of the measuring slide bar has a tape measure frame, A tape measure is installed in the tape measure frame, the tape measure has a ruler with double-sided scale, the ruler passes through the measuring slide bar and the column, the lower end of the ruler is fixed on the base, the zero scale line of the ruler is connected with the base There is a first distance between the upper surfaces, and there is a second distance between the reference line of the observation window and the lower surface of the measuring crossbar, and the first distance is equal to the second distance.

Further technical solutions are:

The upper end of the measuring slide bar is rotatably connected to the measuring cross bar;

The range of the second distance is 6-10cm.

The beneficial effects of the utility model are as follows:

The utility model adopts the combination of the measuring slide bar and the measuring tape, which has simple structure and low manufacturing cost; the weight dial is arranged at the waist of the human body to facilitate reading; the front and rear observation windows are set on the measuring slide bar to reduce the reading error.

Detailed ways

Below in conjunction with accompanying drawing, illustrate the specific embodiment of the present utility model.

See Fig. 1 to Fig. 4, the utility model comprises a base 1, a column 2 is fixedly installed on the base 1, and the sliding device in the column 2 has a multi-section measuring slide bar 4, and the inner and outer sleeves of the measuring slide bars 4 are mutually telescopic; the measuring slide bar 4 The upper end of the upper end is connected to the measuring bar 5 by rotation, and the measuring bar 5 can be retracted when not in use to reduce the occupied space; the weight dial 3 is installed on the column 2, and the weight dial 3 is installed on the upper end of the column 2, which is located above the waist of the human body location, reading is convenient and fast; the upper part of the measuring slide bar 4 has an observation window, and the observation window includes a front window 41 arranged on the front side of the measuring slide bar 4 and a rear window 42 arranged on the rear side of the slide bar 4. The front window 41 is convenient The measured person directly reads, and the rear window 42 is suitable for measuring the operator's reading; the upper end device of the measuring slide bar 4 has a tape measure frame 7, and a tape measure 6 is installed in the tape measure frame 7, and the tape measure 6 has a ruler sheet 61 with a double-sided scale. The sheet 61 passes through the measuring slide bar 4 and the column 2, and the lower end of the ruler sheet 61 is affixed to the base 1. When the measuring slide bar 4 stretches up and down, the ruler sheet 61 is also elongated or shortened thereupon;

There is a first distance between the zero scale line of the scale 61 and the upper surface of the base 1, a second distance between the reference line 43 of the observation window and the lower surface of the measuring crossbar 5, the first distance is equal to the second distance, and the second distance is equal to the second distance. The spacing is determined by the distance from the top of the human head to the eyes. Generally, it is set at 6-10cm, preferably 8cm. Since the first spacing is equal to the second spacing, it can be read directly from the observation window, which can ensure the eyes of the measured person when reading. Look straight up, not squint, so as to avoid errors caused by squint.

The above description is an explanation of the utility model, not a limitation of the utility model. For the limited scope of the utility model, please refer to the claims. The utility model can be modified in any form without violating the spirit of the utility model. the
