Technical Field

[0001] The utility model relates to the technical field of spring strength detection, in particular to a spring tensile strength detection device. Background Art

[0002] A spring's tensile strength refers to the maximum stress it can withstand when subjected to a tensile force. The type of spring material significantly influences its tensile strength. For example, high-carbon steel springs typically have higher strength and hardness, resulting in a relatively high tensile strength. Stainless steel springs, on the other hand, offer better corrosion resistance but may have slightly lower tensile strength than high-carbon steel springs.

[0003] When testing the tensile strength of a spring, the tensile performance of the spring is tested by stretching the spring and observing the state of the spring when it is stretched to a specific value. The existing spring testing device does not have any protective equipment. When the spring is stretched, the spring may collapse, and the collapsed spring may easily cause injury to the experimenter.

[0004] To this end, the utility model provides a spring tensile strength detection device to solve the above problems. Utility Model Content
