This invention relates to the field of bathing aids technology and discloses an improved shower chair structure, including a chair frame assembly, a seat, a backrest, and armrest assemblies. The chair frame assembly is formed by hinged front and rear frames, and a load-bearing structure for mounting the seat is provided between the chair frame assemblies. The load-bearing structure includes a first pivot support at the hinge of the front and rear frames and a second pivot support composed of a first load-bearing column, a second load-bearing column, and a connecting rod. One end of the connecting rod is pivotally connected to the seat by a bolt, and the other end is fitted onto the first load-bearing column. The top end of the connecting rod is placed in a connecting rod limiting groove, and the connecting rod also has a pointed protrusion that abuts against the end of the connecting rod limiting groove when folded. This solves the technical problem in the prior art that shower chairs cannot stand freely after folding and sometimes open on their own, causing safety issues. It provides a new shower chair structure that is simple in structure, low in cost, ergonomically designed, sturdy in support, safe and stable in opening and closing, and healthy and comfortable.

This utility model discloses a combined extrusion die for aluminum alloy profiles, belonging to the field of aluminum alloy profile die technology. It includes an extrusion die and a forming tube. Fixed plates are fitted at both ends of the forming tube. Connecting ears are provided at the corners of the fixed plates and the extrusion die. Fins, flush with the edges of the fixed plates, are evenly spaced on the surface of the forming tube. Extrusion strips are provided on the inner wall of the forming tube. By evenly spaced fins on the outer side of the forming tube, the tube's strength is enhanced while the high temperature transmitted from the material to the forming tube is quickly dissipated outwards, causing the temperature of the material moving inside the forming tube to decrease accordingly. This gives the material a certain strength within the forming tube. Simultaneously, the extrusion die and forming tube form the material in two stages, allowing for segmented processing of the material. This distributes the pressure generated during processing, preventing the material from rapidly losing temperature and pressure after leaving the processing area, thus avoiding deformation.
