[0018] In order to more clearly describe the present invention, the present invention is further described below in conjunction with specific embodiments. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figures 1 to 3 The adjustable rotating headrest of a bathing chair shown in the figure comprises a push rod 1, a rotating assembly, a headrest assembly, a rotating limit assembly, a sleeve 2, a connecting piece 11 and a locking mechanism 3. The push rod 1 is connected to the headrest assembly through the rotating assembly and the rotating limit assembly. The push rod 1 is provided with a sleeve 2 on the outside, and the sleeve 2 is provided with a locking mechanism 3 for locking the push rod 1. The sleeve 2 is provided with a connecting piece 11 for connecting to the bathing chair. Slide rails are provided on both sides of the push rod 1, and a slide groove matching the slide rails is provided in the sleeve 2. One end of the longitudinal mounting tube 10 is provided in the connecting piece 11, and the other end is connected to the bathing chair.

[0020] In this embodiment, the sliding sleeve 2 and the locking mechanism 3 are fixed together preferably by means of rivets.

[0021] In this embodiment, the locking mechanism 3 is preferably a toggle switch.

[0022] The rotating assembly includes a rotating rod 12 and a rotating ball head 7. One end of the rotating rod 12 is connected to the push rod 1 through a fixing member 4, and the other end is fixedly connected to the rotating ball head 7. A cavity is provided in the push rod 1, and the rotating rod 12 is detachably inserted in the cavity.

[0023] The rotation limit assembly includes a mounting seat outer shell 5 and an inner shell 6. The mounting seat outer shell 5 is provided with a mounting groove for mounting the inner shell 6. The mounting seat outer shell 5 and the inner shell 6 are both provided with through holes for the rotation rod 12 to pass through. The headrest assembly includes a headrest frame 8 and a foamed outer skin 9. The headrest frame 8 is arranged above the rotation limit assembly. The headrest frame 8 is fixedly connected to the mounting seat outer shell 5 and the inner shell 6. The headrest frame 8 is placed in a mold during foaming, and the foamed outer skin 9 is solidified on the headrest frame 8 by foaming. A cavity for accommodating the rotating ball head 7 is provided between the headrest frame 8 and the rotation limit assembly. The headrest assembly and the rotation limit assembly are rotationally connected to the rotating ball head 7, so that the headrest can rotate in multiple directions.

[0024] like Figures 1 to 3 The utility model shows an adjustable rotating headrest for a bathing chair. When the locking mechanism 3 is closed, the bottom of the locking mechanism 3 is close to the push rod, and the push rod 1 and the sliding sleeve 2 are locked together by friction. When the headrest assembly needs to be adjusted in height, the locking mechanism 3 is lifted upward, and a gap appears between the push rod 1 and the sliding sleeve 2 to unlock the lock, and the push rod 1 is pushed, so that the sliding sleeve 2 and the push rod 1 can slide relative to each other. At this time, the rotating assembly and the headrest assembly can move together with the push rod 1, thereby realizing the headrest height adjustment function. The design of the rotating ball head 7 allows the headrest assembly to rotate in multiple directions, thereby realizing the rotation function of the headrest, providing multi-angle head support and protection for the user.

[0025] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any modification without creative work made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
