Description

Technical Field

[0001] This application relates to the technical field of tensile testing, and specifically relates to a rubber tensile tester. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformations under very small external forces, and can return to its original state after the external force is removed. Rubber belongs to a completely amorphous polymer;

[0003] After rubber is produced, it needs to be inspected. Among them, the tensile property test of rubber is one of the important indicators. When users conduct the test, an instrument will use a tensile testing machine for testing. By fixing both ends of the rubber on the clamping device of the tensile testing machine, and then starting the traction component to drive the clamping device to continuously stretch the rubber until the rubber breaks, the tensile ability of the rubber can be obtained. In order to test the tensile force of various parts of the rubber, generally two tensile testing devices are arranged between the two clamping devices to test other parts of the rubber.

[0004] For example, the patent with the publication number CN220982904U specifically discloses a rubber strip tensile ability testing device, including a fixed base, a fixed frame, a sliding rod, a threaded rod and a clamping device. Thus, it can be achieved that the two clamping devices can be driven to move away from each other through the threaded rod and the sliding rod, avoiding jitter when the clamping device stretches the rubber strip and ensuring the accuracy of the test results.

[0005] When the above-mentioned patent tensile tester is in use, two clamps clamp the rubber strip, and then two tensile ability testing devices are clamped on the surface of the rubber strip. The motor is started to rotate the two threaded rods, so that the two sliding frames move away from each other to conduct a tensile test on the rubber. However, since the stretching components are exposed outside, rubber and plastic bounce occurs during the process of the rubber breaking, which may cause harm to the testing personnel. Therefore, it is necessary to design a rubber tensile tester to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

However, since the tensile components are exposed outside, rubber and plastic bounce occurs during the process of rubber breaking, which may cause harm to the testers.

[0009] Further, the fixing mechanism includes side plates installed on both sides of the first transparent cover. An extending plate is installed on the concave frame, and a mounting seat is installed on the extending plate. Hinged rods are rotatably installed on both sides of the mounting seat. One end of each hinged rod is installed with a spring, and a hanging rod is connected between the two groups of springs. A hook rod is installed on the side plate.

[0010] Further, a round rod is installed on the concave frame, a limiting rod is installed on the test bench, and a first cross plate is installed on the concave frame.
