Description

Technical Field

[0001] The utility model relates to the technical field related to detection devices, and in particular to a polyurethane elastomer shock-absorbing material performance detection device. Background Art

[0002] Among organic elastomer materials, polyurethane elastomers have the best mechanical properties, including tensile strength, tear strength and wear resistance. Polyurethane elastomers are used as elastomer shock absorber materials, especially in situations where high load-bearing capacity requirements are required. They have been fully recognized and widely used in the industry.

[0003] When testing the performance of polyurethane elastomers, they first need to be subjected to a tensile test. Generally, a specimen of a certain length, diameter and wall thickness is cut from the polyurethane elastomer and then placed in a fixture for testing. Current fixtures generally use a screw rod to drive the clamp to clamp the clamp, but after each stretching, broken test pieces and debris will remain inside the machine body, requiring staff to clean them up after each test. Some debris will remain on the fixture or the screw rod, which can easily affect the normal use of the fixture and is relatively inconvenient. Utility Model Content
