Description

technical field [0001] The invention relates to an adjustable head-mounted locking mechanism, which is used on a strap of a head-mounted device to adjust the tightness of the strap. Background technique [0002] At present, head-mounted 3D glasses products in the market usually adopt bandage type. Its tightness adjustment mechanism is mainly made up of bandage and adjustment buckle. The main disadvantages of this type of adjustment mechanism design are: (1) It is not easy to adjust the tightness after wearing the head; (2) The service life of the strap is relatively low; (3) It takes up a lot of space. [0003] The product structure of other head-mounted 3D glasses is as follows: [0004] An adjustable head-mounted locking mechanism is disclosed in the Chinese utility model patent "Ring-shaped headband and head-mounted device with the same" (CN205139466U), which is provided with a connecting strap and an adjustable locking plate. Both are equipped with transmission teeth,...
