[0021] Please refer to Figures 1 to 4 This invention provides a height-adjustable bathtub grab bar, comprising a base 10, a grab bar body 20, and a locking component 30. The base 10 is provided with a receiving tube 11. The grab bar body 20 includes an adjusting tube 21 with one end extending into the receiving tube 11 and a grab bar 22 integrally connected to the other end of the adjusting tube 21. In this embodiment, the grab bar is an arc-shaped grab bar. In other embodiments, the grab bar can also be other shapes, such as U-shaped, elliptical, or circular. The adjusting tube 21 has multiple positioning holes 211 along its length. The receiving tube 11 forms an annular groove 111 around its outer circumference. The annular groove 111 is provided with a locking hole 112 that can be aligned with any of the positioning holes 211. The locking component 30 includes an arc-shaped quick-connect clip 31 and a locking mechanism fixed inside the arc-shaped quick-connect clip 31. The locking pin 32 is rotatably connected at one end to the annular groove 111, and the other end of the arc-shaped quick-connecting clip 31 can clamp and position itself in the annular groove 111. The locking pin 32 is then inserted into the lock hole 112 and the positioning hole 211 aligned with the lock hole 112, thereby connecting and positioning the adjusting tube 21 within the receiving tube 11. In this invention, adjusting the height of the armrest body 20 is equivalent to adjusting the distance between the armrest body 20 and the base 10. The user only needs to pry the arc-shaped quick-connecting clip 31 to disengage the locking pin 32 from the lock hole 112, which allows the adjusting tube 21 to move. When the desired height is reached, the locking pin 32 is inserted through the lock hole 112 into the corresponding lock hole 112 to connect the receiving tube and the adjusting tube together, achieving a locking effect.

[0022] In this embodiment, the annular groove 111 is defined by two radial flanges 111A extending radially outward around the outer circumference of the receiving tube 11. In some embodiments, as long as the wall of the receiving tube 11 is thick enough, the annular groove 111 can also be formed by the outer circumference of the receiving tube 11 being radially recessed inward. One end of the arc-shaped quick-connect clamp 31 is rotatably connected to the two side walls of the annular groove 111 via a rotating shaft A. The other end of the arc-shaped quick-connect clamp 31 is provided with a positioning part 311. The arc-shaped quick-connect clamp 31 and the locking pin 32 are integrally formed. Whether made of metal or plastic, the positioning part 311 can be clamped to the bottom wall of the annular groove 111 by means of the arc-shaped characteristics of the arc-shaped quick-connect clamp 31.

[0023] In this embodiment, in order to quickly pry open the arc-shaped quick-connect clip, a prying part 312 is provided at the end of the arc-shaped quick-connect clip 31 on the same side as the positioning part 311, so as to achieve the effect of quickly separating the arc-shaped quick-connect clip 31 from the receiving tube 11.

[0024] To better lock and position the arc-shaped quick-connect clip 31, the bottom wall of the annular groove 111 is provided with a positioning groove 113 for the positioning part 311 to be inserted into, so as to increase the stability of the connection and positioning of the receiving tube 11 and the adjusting tube 21 and prevent loosening. In addition, the user can quickly separate the positioning part 311 of the arc-shaped quick-connect clip 31 from the positioning groove 113 with one hand through the lever part 311, without the need for two fingers of one hand or both hands to operate, thus achieving a quick height adjustment effect.

[0025] In this embodiment, there are two receiving tubes 11, and correspondingly, there are also two adjusting tubes 21. Figure 5 As shown, the anti-slip sleeve is made of PVC.

[0026] In this embodiment, as Figure 4As shown, the base 10 includes an L-shaped main clamping block 12, a secondary clamping block 13, an L-shaped square tube 14, a screw 15, and an adjusting handle 16. A receiving square tube 17 is fixed to the top of the L-shaped main clamping block 12. The receiving tube 11 is fixedly disposed on the top of the L-shaped main clamping block 12. One end of the L-shaped square tube 14 is movably inserted into the receiving square tube 17. The secondary clamping block 13 is movably connected to the L-shaped square tube 14 via a pivot (not shown) and faces the L-shaped main clamping block 12. One end of the screw 15 extends into the receiving square tube 17 and is screwed to the end of the L-shaped square tube 14. The adjusting handle 16 is fixed to the other end of the screw 15. In this embodiment, the L-shaped square tube 17 can move in the receiving square tube 17 but cannot rotate. Therefore, by rotating the screw 15 through the adjusting handle 16, the screw 15 is screwed into the L-shaped square tube 14, so as to achieve the effect of the L-shaped square tube 14 moving in the receiving square tube 17. This allows the distance between the secondary clamping block 13 and the L-shaped main clamping block 12 to be adjusted by rotating the adjusting handle 16. In actual use, the L-shaped main clamping block 12 and the secondary clamping block 13 are clamped at a predetermined position in the bathtub through the cooperation of the secondary clamping block 13.

[0027] This utility model is installed in a bathtub or other location where a handrail is needed for support. Users can quickly lock or unlock the receiving tube and the adjusting tube by manually bending the arc-shaped quick-connect clip, making it convenient for children to use and achieving a quick height adjustment effect.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
