A device for testing tensile strength

Abstract

The present invention discloses a tensile strength testing device. The tensile strength testing device comprises a frame body, a stretching device disposed inside the frame body, and a gas injection device mounted on the upper end of the frame body, the stretching device comprises a first air chamber on the right side of the stretching device, and a first movable block on the left side of the first air chamber, and the first movable block is slidably coupled with the first air chamber, a first sealing recess is disposed on the side of the first movable block, a first sealing ring is disposed in the first sealing recess, a first movable bar is disposed on the left side of the first movable block, and the right side of the first movable bar is fixedly coupled with the first movable block, the left end of the first movable bar is fixedly provided with a stretching rod, the right end of the stretching rod is fixedly coupled with the first movable bar, and the left end of the stretching rodis fixedly connected with a clamp .

Description

technical field [0001] The invention relates to the technical field of tensile strength testing, in particular to a tensile strength testing device. Background technique [0002] In today's life and production process, it is necessary to test the tensile strength of some strips. For example, the safety belts that we use every day when we travel in the car, and the transport belts used to drive and transport items in the construction area must ensure a certain strength. , otherwise it will cause an unpredictable accident, so these safety belts, belts and other items need to be sampled for tensile strength testing before or during mass production, but the lack of special equipment for strength testing of these items , so many companies can only outsource these tests to other companies or research institutes, which is not only costly, but also slow to respond to the test results, often after a large number of products are produced, the test results are not known until they are ...

Problems solved by technology

[0002] In today's life and production process, it is necessary to test the tensile strength of some strips. For example, the seat belts we use every day when we travel by car, and the transport belts used for transporting items on the construction site must ensure a certain strength. , otherwise it will cause unpredictable accidents. Therefore, before or during the mass production of these seat belts and belts, samples are required to be tested for tensile strength. However, due to the lack of special equipment for strength testing of these items , so many companies can only outsource these tests to other companies or research institutes, which is not only costly, but also slow to respond to the test results, often after a large number of products are produced to know whether the test results are qualified, so a simple and effective design Tensile strength testing device, it is very necessary for enterprises to conduct product testing by themselves
