Description

Injector protective cap unscrewing torque detection equipment Technical Field The utility model relates to the technical field of torque detection, in particular to a device for detecting unscrewing torque of a protective cap of an injector. Background As a common medical apparatus, the screwing and unscrewing performance of the protective cap of the syringe is directly related to the use safety and the operation convenience. The protective cap is used as an important component of the injector, and mainly plays roles of sealing the needle, preventing pollution and protecting medical staff and patients. Before clinical use, medical staff need unscrew the protective cap to carry out injection operation, and whether the unscrewing torque of the protective cap is in a reasonable range is one of key indexes for measuring the use performance of the injector.
