Description

Technical Field

[0001] The utility model relates to the technical field of safety belts, in particular to a safety belt detection device. Background Art

[0002] Seat belts are safety parts used on equipment. They are belts used to ensure safety when riding in aircraft such as airplanes, or when working at high altitudes and performing skills. The main raw materials are polyester, polypropylene, and nylon. Seat belts do not only refer to webbings. In addition to webbings, seat belts are assembled from other parts.

[0003] During the production of seat belts, a testing device is used to test the toughness of the seat belts. When testing the seat belts, due to the influence of tension on both sides, when the seat belts are subjected to too much tension, the seat belts will break after bearing a large tension. When the seat belt breaks, the testing device cannot quickly remove the traction force, and the force acting on the testing device can easily cause damage to the testing device, thereby reducing the service life of the testing device.
