Abstract

The invention relates to a small electronic tension tester. Two lead screws are vertically arranged at the upper end of a working table board, polish rods at the upper ends of the lead screws are connected to inner holes of a bearing partially; inner holes in two ends of a fixed cross beam are fixedly connected to the outer diameter of the bearing; the two lead screws can rotate in the bearing holes in two ends of the fixed cross beam, a loading cross beam is vertically arranged between the middle ends of the two lead screws, two ends of the loading cross beam are connected to lead screw nuts,the lead screw nuts are in engaged connection to the lead screws, and the loading cross beam can move up and down on the lead screws. The small electronic tension tester provided by the invention hasthe technical effect that the small electronic tension tester has the advantages of a small size, a simple structure, steady loading, large selection range of the loading speed, a rate selecting range of 0.5-200 mm/min, digital display of a force value and the like.

Description

technical field [0001] The invention relates to an electronic tensile testing machine, in particular to a small electronic tensile testing machine. Background technique [0002] At present, there are various types of electronic tensile testing machines for testing the tensile strength of various materials. The smallest measurement unit of these devices is expressed in Newton (N), and the minimum resolution is only 0.2 Newton. However, the tensile strength of many materials All are smaller than 0.2 Newton, such as the strength of a single cotton, thread, silk, hair, hair, and the test of magnetic force, biological living skin and tiny adhesion between objects. Generally, the electronic tensile testing machine cannot meet the test smaller than 0.2 Newton, which may easily cause large measurement errors or fail to measure the maximum force at all. Contents of the invention [0003] The purpose of the present invention is to provide a small electronic tensile testing machine,...
