Description

1253500 IX. Description of the invention: [Technical field of invention] High-measurement device, in particular, 'received by an ultrasonic wave. The present invention relates to a portable ultrasonic type, which is a small type of ultrasonic wave emitted by an ultrasonic transmitter. The portable ultrasonic height P receives, and then calculates a measuring device for the height of the human body. [Prior Art] There are not many types of height measuring devices used in practice, but there are also several different measuring methods and styles; those who use tape measure, those who use stickers attached to indoor walls, have usage and weight The height measuring device that integrates the meter and the height of the body, the use of a similar high-altitude unilateral device, the body of the singularity of the tooth, the latest type is the height of the coin-operated electronic digital display placed in a public place. Measuring device. Silk analysis shows that various height measuring devices have their own disadvantages: Using tape measure: This method is the most common method used by families to understand the child's growth; its measurement The step is that after the measured person stands against the wall, the measurer must use a straight ruler or a hard plate to gently press on the head of the measured person, so that the ruler or the plate is perpendicular to the wall. The height of the measured person is marked on the wall. When the measured person leaves the wall, the measurer uses the tape measure to measure the height of the floor to the position of the mark. The disadvantage of this method is that the ruler or the plate often cannot be perpendicular to the wall at a temperature of 123500, which causes the inaccuracy in the writing. When measuring, the tape measure often cannot be parallel with the body of the measured person. The offset will cause the error of the measured value'. With the increase of the measurement frequency, the marking on the wall will also increase, which will destroy the neatness and beauty of the wall. 2. Use the paper ruler attached to the wall to measure. · This measurement method is used in the classrooms of kindergartens and national elementary schools. The bedroom walls of ordinary family children are also commonly used for payment; the steps are that the measured person is attached to the room. After the wall of the paper ruler is standing, the tester still needs to use a straight ruler or a hard plate to gently press on the head of the measured person, so that the ruler or the plate is perpendicular to the wall, and the measured person is left. The wall's measurer can read the height of the measured person from the lower edge of the ruler or the plate against the scale of the paper ruler. The disadvantage of this method is the same as the measurement using a tape measure, that is, the ruler or the plate often cannot be perpendicular to the wall at 9 degrees, resulting in a deviation in the value read. 3. Height measuring device integrated with the weight scale: This device is widely used by large and small hospitals or school health schools at all levels; its main disadvantages are large and bulky, difficult to move, and quite expensive, non-general activities. Households with limited space and a low economy can buy users. 4. Height measuring device similar to the unilateral device of the high jump frame: This device is also widely used by large and small hospitals or school health clinics at all levels; its main disadvantages are large and slender, high cost of packaging and transportation, if placed in the family. It also hinders the family's view, so few families buy and use. 5. Coin-operated electronic digital display height measuring device: This device is mainly placed in the public 1253500, which belongs to the business-like family. It can be used in a common place where the general family can do it. For example: a station, a department store, a supermarket, etc. ! With its coin-operated design, it will be – outside the market segment, and the volume is awkward, and the price is not used for purchase. As far as the height measuring device is concerned, it is most common to use a single-side device with a jump-high stand. The packaging cost of the package is not the case of the Republic of China Intellectual Property Office No. 25673 (hereinafter referred to as the citation). Improvement, its main components are: the upper and lower sections of the extrusion type, the base, the sliding rectangular groove and the pressure plate are separated and packaged to reduce the packaging transportation cost; and when it is assembled, the upper and lower (four) extrusion groove The folding element is pivoted so that the class drill piece locked by the upper end of the extruded end just abuts the concave end of the lower end of the lower extrusion type, and the angled white locking piece just abuts the top end of the lower extruded aluminum front end The concave notch' and the hole provided on the end surface of the class locking piece correspond to the locking hole of the flat locking piece locked by the top end of the aluminum extrusion type, and the screw is locked, and then the lower part of the combination is The sleeve is placed in the longitudinal locking block, and the vertical plate of the base plate corresponds to the keyhole of the indented type, and is screwed and locked on the end face of the locking block, and then the sliding rectangular groove is sleeved. In the upper and lower sections of the aluminum extrusion type, that is, the composition - height measurement By. The improvement of the citation case of Guan Guan still cannot be separated from the shortcomings of large size and slenderness after being assembled. Nowadays, the economy is developed and the society is progressing. Parents pay more attention to the growth and over-development of their children. The growth of children is based on the regular measurement of the child's height. The above five conventional height measuring devices have the same or different 1253500 disadvantages, but their common disadvantage is that after the height measurement, the measurement date and the measured value must be recorded in the notebook, otherwise the growth process for the child Whether it is normal, whether it is abnormal or not, it is difficult to accurately grasp it. Therefore, in view of the shortcomings derived from the above-mentioned conventional height measuring instruments, the inventors of the present invention have innovated and developed after a lot of painstaking research, and finally developed a very small, precise measuring and multi-functionality that breaks the tradition completely new. Portable ultrasonic height measuring device for people and multiple memory functions. I hope that this invention will enable every family to grasp the growth of their children simply, quickly and accurately, and contribute to the promotion of health for future owners. It is also expected that every family can easily enjoy innovative technology for us. Convenience.
