Abstract
The utility model provides a hydraulic human body weight measurement device and belongs to the field of hydraulic machinery. The device measures weight of a human body by adopting the principle of liquid force transmission. The device is provided with a hydraulic cylinder. A hydraulic sensing element is switched on the hydraulic cylinder. The weight of the human body is transmitted to the sensing element by liquid in the hydraulic cylinder. A weight signal is displayed by a secondary electronic instrument, or a liquid pressure display meter is directly switched on the hydraulic cylinder to directly display the weight of the human body. The device can accurately measure the weight of the human body, solves the problem of inaccurate indicating value caused by overload and deformation of a spring in the conventional device and has the advantages of low price and good reliability.
Description
Technical field
The utility model belongs to the weight measurement field, is specifically related to a kind of fluid pressure type measuring body weight instrument.
Background technology
Along with the raising of people's living standard, people more and more worry the obesity of health.The variation of monitoring body wt is healthy more and more important to people's.
At present, human body weighing's mode is generally adopted the principle of spring stress deformation, but, cause indicating value inaccurate owing to after the spring overload distortion, be difficult to restore to the original state.
The utility model content
The purpose of this utility model is to solve a difficult problem that exists in the above-mentioned prior art, and a kind of fluid pressure type measuring body weight instrument is provided, and measures human body weight by the principle of using the liquid power transmission, realizes accurately measuring the purpose of human body weight, and cheap, good reliability.
The utility model is achieved through the following technical solutions:
A kind of fluid pressure type measuring body weight instrument comprises weight measurement mechanism and indication mechanism, and described weight measurement mechanism comprises the hydrostatic transmission structure; Described hydraulic gear comprises hydraulic cylinder and piston; Described weight measurement mechanism also comprises foot platform, and described foot platform is horizontally disposed with, and the bottom of described foot platform is connected the axis normal of described foot platform and described piston or piston rod with the piston of described hydraulic cylinder or the external part of piston rod; Described indication mechanism is electrically connected with described weight measurement mechanism.
In order to realize that hydraulic data is weight data by being converted into, and with its output.Described indication mechanism comprises hydraulic pressure transducer, control module, power supply and display assembly; Described hydraulic pressure transducer is connected with described hydraulic cylinder, measures to obtain the interior pressure values of hydraulic cylinder by the human body weight that described control module and display assembly obtain conversion, shows by display screen.
In application, described indication mechanism is the fluid pressure indicator gauge, and described fluid pressure indicator gauge is connected on the described hydraulic cylinder, directly human body weight is shown.Described display assembly adopts the secondary electron instrument.Transfusion screw and tapping screw are installed on the described hydraulic cylinder, and described transfusion screw is installed in the upper surface of pedal platform, and screw passes piston rod and piston center, straight-through hydraulic cylinder, and described tapping screw is installed in the side, below of described hydraulic cylinder.The liquid of filling in the described hydraulic cylinder can be water or hydraulic oil
Compared with prior art, the beneficial effects of the utility model are: utilize this device accurately to measure human weight, solved in the conventional apparatus and be out of shape the problem that causes indicating value inaccurate because spring overloads, and this device is cheap, good reliability.
