description The present disclosure belongs to the technical field of head-mounted products and particularly relates to an adjustable head-mounted structure. The adjustable head-mounted structure comprises a first head strip and a second head strip arranged in an overlapped and staggered manner, and one end of each of the first head strip and the second head strip are respectively arranged in the groove-shaped bracket. The first head strip is fixedly connected with the groove-shaped bracket. A sliding cavity extending in the length direction of the first head strip is provided on an end thereof. A plurality of limiting slots are provided at intervals at a lateral side of the sliding cavity. A notch is provided at the end of the second head strip. An elastic piece is fixedly connected with the second head strip, and comprises a connecting portion, and a bending portion located in the notch. The bending portion is inserted into the sliding cavity and is clamped into one of the limiting slots. An elongated through hole extending in the length direction of the groove-shaped bracket is provided on a sidewall of the groove-shaped bracket which is close to the limiting slot. A button is provided in the groove-shaped bracket and comprises a pressing portion which is to be inserted into the elongated through hole and a baffle plate connected with the pressing portion. A fixed connection structure is provided between the baffle plate and the second head strip. The adjustable head-mounted structure solves the problems of the existing head-mounted structures that length adjustment is inconvenient and the position cannot be fixed after adjusted in place.
