Embodiment approach

[0044] The best way to implement it is:

[0045] The first embodiment is mainly used for the measurement of children, and the second embodiment is mainly used for the measurement of adults. In order to be easy to carry, the measuring rod can be made into a foldable and pull-out type. In the first embodiment, the hand-held part 3 It can be made into a flexible connection with the measuring rod 1, and the flexible connection part can be tightened and fixed after being bent, and the hand-held part 3 is properly extended, which is convenient for measuring when the height of the measurer is smaller than the height of the measured person.

[0046] In the second embodiment, the positioning device 12 can be made into a concave shape or a hat shape to ensure correct positioning. When the positioning device is not at the midpoint of the measuring rod 1, the positioning device 12 can be used to locate the ultrasonic distance measuring probes 2a, 2b respectively. distance, and the paramet...

Abstract

The invention discloses a head placement type height measurement method, which relates to the technical field of the measurement and aims to solve the technical problem of height measurement. The measurement method comprises the following steps of: 1) arranging a ranging probe on a measuring rod; 2) arranging a horizontal device on the measuring rod; 3) placing the measuring rod on the head top of a measured person; 4) observing the horizontal device, and adjusting the measuring rod to a horizontal state; 5) starting the measurement; and 6) displaying a measured value. In the head placement type height measurement method, the influence of hair shape of the measured person on the measurement is avoided because the measuring rod is directly placed on the top of the head of the measured person; moreover, the measured rod is small in volume, low in cost, and convenient to carry.

Description

technical field [0001] The invention relates to a height measurement technology, in particular to a head-mounted height measurement method. Background technique [0002] The currently known height measurement method is to use a skateboard to move from top to bottom, stop when it reaches the person's head, and then calculate the height through the distance moved by the skateboard. The other is to place the ultrasonic distance measuring probe on the person being measured. above. Measure the distance from the probe to the subject's head and calculate the height. However, the former method is bulky and cumbersome, and the measurement accuracy of the latter ultrasonic wave is also affected by the shape of the subject's hair, so the measurement accuracy is not high. Contents of the invention [0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is to provide a head-mounted height measurement method that pl...
