Embodiment 1
[0009] Embodiment 1: The present invention will be further described below in conjunction with the drawings.
[0010] Such as figure 1 with figure 2 Shown: Built-in reference standard height ruler, it includes ruler body 1, scale 2, movable board 3, height reference standard ruler 4, etc. The feature is: ruler body 1 can be made of wood or plastic, divided into three Level, with a scale 2 on the front, a movable board 3 that can be moved up and down is nested on the scale; the middle layer is a height standard 4, the age corresponding to the scale is displayed on the scale (male and female standard left and right columns), and there is a push on the side The rod can push the middle standard ruler to the other side so that it can be clearly seen as a standard reference; the back layer is 5.

The invention belongs to the field of daily necessities, and particularly relates to a height ruler embedded with a reference standard ruler. The height ruler embedded with the reference standard ruler comprises a ruler body, a scale ruler, a movable board, the height reference standard ruler and the like. The ruler body can be made of wood or plastics. The height value can be read conveniently due to the movable board nested on the scale ruler, and therefore the purpose of accurate measurement is achieved. The height requirements which should be met by people of different ages are listed in detail on the height reference standard ruler embedded in the middle layer according to the different sexes, an estimator can visually estimate the height conditions of children, whether the heights of measured people meet the requirement for growth and development or not can be judged without further searching data, and therefore the measurement, assessment and evaluation processes are simple, scientific and fast.
Description
Technical field [0001] The invention relates to a height ruler, which belongs to daily necessities. Background technique [0002] Height is one of the important indexes for clinical evaluation of children's growth and development level, and height rod is a common tool used to measure height. Common height rods generally have only simple scales, from which the evaluator can read the corresponding height value of the child. However, these existing measurement tools generally have problems such as inaccurate measurement and lack of normal reference standards, so that the evaluator cannot accurately and intuitively judge whether the height of the measured person meets the requirements of normal growth and development. Therefore, designing a height ruler with embedded height reference standards helps the evaluator to accurately and quickly evaluate the height level of children. This invention can be widely used in hospitals, schools, homes, etc. Summary of the invention [0003] The ...
