Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
As shown in fig. 1, the present embodiment provides an elastic modulus measuring apparatus, which includes:
a modulus display communicator a having a top port and a bottom port and being disposed in a vertical direction;
a medium container b in a form of being disposed in parallel with the modulus displaying communicating vessel a, the overall shape of the medium container b being the same as the shape of the main body portion of the modulus displaying communicating vessel a (e.g., cylindrical or tubular, etc., and having a top port and a bottom port), while the inside of the medium container b is filled with a liquid medium (not labeled in the figure);
a piston c, which is sleeved in the medium container b from the top port of the medium container b and is in sliding contact with the inner peripheral wall of the medium container b;
a weight holder d contacting an upper surface of the piston c for being connected to a bottom end of the object a to be measured such as a steel wire;
a measured object fixer e which is arranged right above the weight support d and is used for connecting with the top end of a measured object A such as a steel wire, and the specific structure of the measured object fixer e can be selected according to actual requirements, such as a clamp, a hanging device and the like;
and a medium communication pipe f, which may be made of a material such as plastic, for communicating the bottom port of the modulus display communicating vessel a with the bottom port of the medium container b.
The measuring instrument of the embodiment can be used for visually, conveniently, rapidly and accurately measuring the elasticity modulus of the measured object A according to the principle of the communicating vessel; the method specifically comprises the following steps: taking the measured object A as an example of a steel wire, after the steel wire is hung between the measured object fixer e and the weight support d, and the weight B is added on the weight support d, the weight support d can push the piston c to move downwards (at the same time, the steel wire can be stretched), thereby the liquid medium in the medium container b is pressed into the modulus display communicating vessel a through the medium communicating tube f, since the amount of the piston c moving downwards is the elongation of the steel wire, and the elongation is visually represented by the amount of the liquid medium entering the modulus display connector a, during specific design, through the selection and configuration of the volume of the medium container b and the volume of the modulus display communicating vessel a (for example, the inner diameter of the medium container b and the inner diameter of the modulus display communicating vessel a are set in a fixed multiple relation), a tester can accurately, quickly and intuitively obtain an elastic modulus value; meanwhile, the whole measuring instrument is simple in structure, convenient to disassemble and assemble and operate and low in cost, and can effectively meet the measuring requirements for the elastic modulus in various fields.
As a preferable scheme, the liquid medium of this embodiment is preferably castor oil, so that the characteristics of castor oil, such as good fluidity, low friction coefficient and certain color, are utilized, the friction force between the piston c and the medium container b can be effectively reduced, and the test value can be conveniently read by a tester. Of course, other liquids having similar properties may be used for the liquid medium.
In order to simplify the structure of the whole measuring instrument to the maximum extent and provide favorable conditions for the testers to read the test values intuitively, quickly and accurately, the modulus display communicating instrument a of the embodiment comprises a scale plate 10 arranged along the vertical direction and a communicating pipe 20 arranged on the scale plate 10 along the vertical direction, the scale plate 10 is provided with scale gauges 30 distributed in parallel with the communicating pipe 20, the bottom port of the communicating pipe 20 is connected with the bottom port of a medium container b through a medium communicating pipe f, and the top port is communicated with the outside. Therefore, after the liquid medium is squeezed into the communicating pipe 20, the tester can quickly obtain the test value through the scale table 30 corresponding to the liquid level of the communicating pipe 20, so that the elastic modulus value of the steel wire is finally obtained through the inner diameter configuration relationship between the medium container b and the communicating pipe 20.
As a preferable aspect, the communication pipe 20 of the present embodiment may adopt a tubular structure body made of a transparent material such as plastic, glass, or the like, as the case may be.
In addition, in order to increase the magnification, the inner diameter of the medium container b of the present embodiment is an integral multiple (e.g., 10 times, etc.) of the inner diameter of the communication pipe 20. Therefore, when the piston c pushes the liquid medium to move downwards by a small amount in the medium container b, the liquid level in the communicating pipe 20 rises by a large amount according to the principle of the communicating device, and the elongation of the steel wire can be amplified by multiple times by utilizing the multiple relation between the medium container b and the inner diameter of the communicating pipe 20, so that a tester can conveniently obtain corresponding test values.
The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings, or directly or indirectly applied to other related technical fields, are included in the same way in the protection scope of the present invention.
