AI Technical Summary
The existing leather tensile strength detection device lacks clamping force when the tension increases, resulting in loosening of the leather and unstable air pressure during cylinder stretching, resulting in distortion of the test data.
A leather tensile strength detection device is designed, using inverted "U" grooves to clamp the leather, and gradually apply tension through the screw, combined with handwheel and screw locking to ensure clamping stability and accuracy of test data.
The clamping stability is improved through the inverted "U" groove clamping and screw locking design, ensuring the accuracy of the test data, and avoiding the problems of leather loosening and air pressure instability.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of leather detection, in particular to a leather tensile strength detection device. Background Art
[0002] Before leather leaves the factory, its indicators need to be tested, such as color fastness, tensile strength, corrosion resistance, etc. At present, the tensile strength testing device clamps the leather with a chuck for tensile testing, wherein the chuck includes an upper clamping plate and a lower clamping plate, and the upper clamping plate and the lower clamping plate press each other to clamp the leather. During the stretching process, due to the gradual increase in tension, before the leather breaks, the leather is easy to loosen from between the upper clamping plate and the lower clamping plate due to insufficient clamping force, resulting in test failure. Moreover, the cylinder is currently used to stretch the leather. During the test, the air pressure is prone to instability. When the air pressure is too high, the leather is easily broken at once, resulting in distortion of the test data. Utility Model Content
