Description

Technical Field

[0001] The utility model relates to a walk-in bathtub door with a positioning and locking device. Background Art

[0002] Existing bathtub door locks usually drive a locking bolt to lock by swinging a handle to drive a connecting rod. For example, a bathtub door lock disclosed in Chinese invention patent CN102561847B includes a seat fixed to the bathtub door, a handle member, a lever, a locking bolt, a locking bolt connecting rod, a conduit, and a locking bolt access port. The seat is provided with a groove. The handle member includes a handle and a swinging member connected to the handle. The swinging member is swingably connected in the groove via a rotating shaft. The lower end of the swinging member is provided with a clamping groove, and a shaft is provided in the clamping groove. One end of the lever is provided with a sliding groove. The fulcrum of the lever body is hinged to a bracket in the bathtub door. One end of the lever is provided in the clamping groove. The shaft in the clamping groove passes through the sliding groove. The other end of the lever is hinged to one end of the locking bolt connecting rod. The other end of the locking bolt connecting rod is hinged to one end of the locking bolt. The conduit is transversely provided on the side of the bathtub door. The other end of the locking bolt is connected to the conduit. The locking bolt access port is provided on the bathtub frame corresponding to the conduit. When in use, the handle drives the swinging member to swing, and the swinging member drives the lever to swing along the fulcrum, and the lock bolt is driven into / out of the lock bolt access port on the bathtub frame by the lock bolt connecting rod to lock the closed bathtub door or unlock the bathtub door lock.

[0003] The handle of this solution needs to be limited in its swing range by a seat on the bathtub. The limit seat is protruding from the bathtub door, which takes up a lot of space and hinders the bathtub user's arm placement. In addition, a groove is required on the seat to limit the range of handle movement, which increases the difficulty of sealing. Utility Model Content
