Abstract
The invention relates to an electric tensile resistance tester which is characterized by comprising a bracket and pulleys. Two pulleys are arranged on the top of the bracket, a scale is arranged on the bracket; one end of a first pulley is connected with a fixed weight test device through a steel wire, the other end of the first pulley is connected with a second pulley through a steel wire, and the second pulley is connected with a motor through a steel wire. The fixed weight test device comprises a gravity sensing device, a hook, a control box and a liquid crystal display screen, wherein the hook is arranged at the lower end of the gravity sensing device, the gravity sensing device is connected with the control box through a wire, and the control box is provided with the liquid crystal display screen. The bracket is an expansion bracket. By adopting three tensile tests, the telescopic bracket can test objects with different lengths. The practical ability of a student is cultured through an electric tensile resistance test, and different tensile resistance ability of different materials can be tested. The creative spirit and the scientific capacity of the student are cultured through a test activity.
Description
Technical field
The present invention relates to a kind of tensile resistance tester, relate in particular to a kind of electric tensile resistance tester.
Background technology
The student is in the test of the different stretching resistance of experimental determination different materials, adopt usually manual from the scale the distortion situation of Direct observation object, waste time and energy like this, and error is big out of true.
Summary of the invention
Have defective for overcoming prior art, real time reaction goes out the stretching resistance data when the invention provides a kind of test, observes the electric tensile resistance tester of deformation of body situation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of electric tensile resistance tester, be characterized in, comprise support, pulley, prop up top of the trellis and be equipped with two pulleys, be equipped with scale on the support, described first pulley, one end is connected and fixed Weight measurement device by steel wire, the other end connects second pulley by steel wire, and described second pulley connects motor by steel wire.
The said fixing Weight measurement device comprises gravity sensing device, hook, and control enclosure, LCDs, described gravity sensing device lower end is equipped with hook, and gravity sensing device connects control enclosure by lead, on the described control enclosure LCDs is set.
Above-mentioned support is an expansion bracket.
Beneficial effect of the present invention: can adopt three kinds of tensile tests, telescope support, but test objects with different lengths.Gravity sensing device and LCDs go out the pulling force situation in the test real time reaction.The fixed weight determinator is determined certain pulling force before survey, stop drag when reaching predetermined pull, observes the distortion situation of object.Scale: needed pulling force situation when deformation of body arrives to a certain degree.By electric tensile resistance test cultures students practise manipulative ability, can measure the different stretching resistance ability of different materials, by measuring movable students innovation spirit and the science power cultivated.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1: a kind of electric tensile resistance tester, be characterized in, comprise support 1, pulley 2, described support 1 top is equipped with two pulleys, is equipped with scale on the support, and described first pulley, one end is connected and fixed Weight measurement device 7 by steel wire 8, the other end connects second pulley by steel wire, and described second pulley connects motor 10 by steel wire.
Fixed weight determinator 7 comprises gravity sensing device 6, hook, and control enclosure 4, LCDs 5, described gravity sensing device lower end is equipped with hook, and gravity sensing device connects control enclosure 4 by lead, on the described control enclosure 4 LCDs 5 is set.The fixed weight determinator is determined certain pulling force before survey, stop drag when reaching predetermined pull, observes the distortion situation of object.Scale: needed pulling force situation when deformation of body arrives to a certain degree.Gravity sensing device and LCDs go out the pulling force situation in the test real time reaction.
Support 1 is an expansion bracket.But test objects with different lengths.
Three kinds of tensile tests by electric tensile resistance test cultures students practise manipulative ability, can be measured the different stretching resistance ability of different materials, cultivate students innovation spirit and science power.
