Double-ruler-strip height measurer bringing convenience to observation

Abstract

The invention discloses a double-ruler-strip height measurer bringing convenience to observation, and relates to a measuring tool. The double-ruler-strip height measurer brings convenience to measurement and the observation. A user does not need to bend over. Particularly, a person to be measured can directly see and read the height measurement value of the person when the person is measured. According to the technical scheme, the double-ruler-strip height measurer comprises a foot plate, a bottom bar, a draw rod, a range pole and a weighing meter. A flexible ruler is arranged at the top end of the draw rod. The flexible ruler comprises two overlapped ruler strips. Ruler heads of the ruler strips are both vertically pulled downwards in parallel and penetrate through all sections of the draw rod until the ruler heads are fixedly connected with a portion, located at the same horizontal position as the foot plate, of the bottom bar, namely a bottom bar lower end tip. Opposite windows for the observation are arranged in a draw rod tube wall at a position slightly lower than the top end of the draw rod in a front-and-back mode. A round stay bar which separates the two ruler strips towards the front and the back respectively in a supporting mode is arranged on the draw rod tube wall and between the two windows for the observation in the radial direction. The value of the distance between the windows for the observation and the top end of the draw rod is the start value, from the ruler heads, on the ruler strips. The double-ruler-strip height measurer bringing convenience to the observation is suitable for various height measuring activities.

Description

Technical field: [0001] The present invention is related to a measuring appliance, specifically a height measuring device. Background technique: [0002] Height-measuring instruments are widely distributed in places such as physical examination and medical treatment, and are important tools for people to understand their own or the physical condition of the person being measured. At present, such special-purpose instruments that are widely seen are generally assembled with weight measuring scales and have dual functions. Yes, the ruler rod used for measuring height is set in the form of a multi-section hollow drawer rod whose thickness gradually changes from low to high. When measuring height, the thinnest section is generally pulled out first, and then pulled down section by section as needed. The readings are taken from the engraved values ​​at the joints of the upper and lower joints. Because the position here is relatively low, it is necessary to bend down to get accurat...

[0002] Height-measuring instruments are widely distributed in places such as physical examination and medical treatment, and are important tools for people to understand their own or the physical condition of the person being measured. At present, such special-purpose instruments that are widely seen are generally assembled with weight measuring scales and have dual functions. Yes, the ruler rod used for measuring height is set in the form of a multi-section hollow drawer rod whose thickness gradually changes from low to high. When measuring height, the thinnest section is generally pulled out first, and then pulled down section by section as needed. The readings are taken from the engraved values ​​at the joints of the upper and lower joints. Because the position here is relatively low, it is necessary to bend down to get accurate readings every time you observe. Frequent use of the pull rod can also easily lead to engraved engraved marks on the wall of the pull rod. The marks of lines and numbers become blurred. In addition, as the measured person, he cannot directly see and read his own height measurement value while measuring. Therefore, people need a kind of improved and easy-to-observe height measurement tool. to facilitate their measurement activities
