Abstract: The present invention discloses a shower adjustment structure that keeps the water outlet direction within a predetermined range at all times, enables rapid adjustment for more convenient operation, and is foldable to reduce occupied space. The structure includes a slide rod, a water inlet device, a first structural member, a second structural member and an operating member. A guide portion is arranged on the slide rod, and the water inlet device is mounted on the slide rod. Two ends of the first structural member are pivotally fitted to the water inlet device and the second structural member respectively. The operating member is pivotally fitted to the second structural member and mounted on the slide rod through guiding fit, with its motion trajectory constrained by the guide portion. Under external force, the operating member changes its posture relative to the guide portion to undo its locked state with the guide portion.

Abstract: A shower support arm assembly includes a support arm body with an adjustment slot extending along a first direction. A sliding adjustment seat is disposed in the slot and can reciprocate along the first direction. At least one rack is fixed on an inner wall of the slot. A paired engagement structure on the adjustment seat engages with the rack in a locked state to position the seat, and moves away from the rack in an unlocked state to release the engagement, allowing the seat to move. This enables a showerhead installed on the seat to have its height adjusted by sliding along the slot. The engagement with the rack after adjustment ensures a stable and reliable position, preventing slippage or displacement.

Abstract: A shower fixing device includes a fixed seat and a movable arm. The fixed seat has a switch valve, a water inlet end, a first water outlet end, and a second water outlet end. The switch valve controls communication between the water inlet end and the first and/or second water outlet ends. The movable arm contains no waterway; one end is rotatably connected to the fixed seat, and the other end holds a first shower. The movable arm rotates 360 degrees around the fixed seat. The first water outlet end connects to the first shower via a flexible hose, while the second water outlet end supplies a second shower. This allows water output at different heights or left-right positions to meet various user needs. Moreover, the absence of a waterway in the movable arm prevents leakage during frequent rotation.
