Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of shower room sliding door fixing devices, specifically to a side-moving movable arm. Background Technology
[0002] Shower Enclosure: A separate shower cubicle. Modern homes have increasingly higher requirements for bathroom facilities, and many families desire a separate bathing space. However, due to limited bathroom space, bathing facilities and sanitary ware must be placed in one room. A shower enclosure makes full use of a corner of the room, clearly defining the shower area with a partition, forming a relatively independent bathing space.
[0003] Shower room sliding doors come in various types, including hinged, sliding, and rotating sliding types. Among them, rotating sliding doors require the door to rotate and move to one side, meaning that the door slides while rotating. Since shower room doors are mostly made of glass and are quite heavy, the support and fixation of the door are particularly important. Existing fixing devices have poor stability and high resistance to door rotation, which needs to be improved. Utility Model Content
