The state after pushing the seat cushion 1 to the left is as follows Figure 5In addition, a rotating device 7 is provided between the slide seat 3 and the seat cushion plate 1, and the seat cushion plate 1 can rotate relative to the slide seat 3, so that the seat cushion plate 1 can slide and rotate, thereby realizing multifunctional azimuth adjustment.
[0028] Key References Figure 1-5 The utility model also limits the sliding of the slide seat 3 by means of the limit latch 5, so as to prevent the seat pad 1 from continuing to slide after being adjusted into place. Specifically, the slide seat 3 is provided with a mounting hole 31, the plug sleeve 4 is installed on the mounting hole 31 and is connected to the mounting hole 31, the limit pin 5 is slidably inserted in the plug sleeve 4, the head of the limit pin 5 is exposed from the plug sleeve 4, the tail of the limit pin 5 is provided with a circle of flange 51, the return spring 6 is sleeved on the limit pin 5, and one end of the return spring 6 is connected to the plug sleeve 4, and the other end is abutted against the flange 51, and the supporting leg 2 is provided with a plurality of limit holes 211 along the length direction. After the slide seat 3 slides into place, the mounting hole 31 can be aligned with the limit hole 211, and the tail of the limit pin 5 can pass through the mounting hole 31 to be inserted into the limit hole 211. The original state of the return spring 6 is a stretched state. In this state, the limit pin 5 is inserted into the limit hole 211, and the slide seat 3 cannot slide.
[0029] When the position of the seat cushion 1 needs to be adjusted, the limit pin 5 can be pulled outward, the return spring 6 is compressed, the tail of the limit pin 5 is disengaged from the limit hole 211, the limit of the slide seat 3 is released, and the position of the seat cushion 1 can be adjusted by pushing the seat cushion 1; the limit pin 5 can be loosened after the slide seat 3 slides, and during the sliding process, the return spring 6 is in a compressed state until it slides into place, the mounting hole 31 is aligned with the limit hole 211 again, the return spring 6 automatically resets, and the tail of the limit pin 5 is pushed to be inserted into the limit hole 211 again to position the seat cushion 1. The utility model can not only adjust the position of the seat cushion 1, but also after the position adjustment is completed, the seat cushion 1 will no longer continue to slide, and will not affect the use of the bathing chair.
[0030] One end of the return spring 6 can be fixed or abutted against the plug sleeve 4. In this embodiment, abutment is adopted. A step abutting against one end of the return spring 6 is provided inside the plug sleeve 4, and the limit latch 5 will not fall out of the plug sleeve 4.
[0031] Key References Figure 1 and Figure 6The support bracket 2 includes four brackets 22 and two support brackets 21. One support bracket 21 connects the tops of the two brackets 22 to make the support bracket 2 present an inverted U shape. The two support brackets 21 are arranged in parallel to form a slide rail. Only one slide seat 3 can be slidably arranged on the two support brackets 21, or a slide seat 3 can be arranged on each support bracket 21. In the present embodiment, the slide seat 3 is a sliding sleeve arranged on the support bracket 21. Each support bracket 21 is provided with a slide seat 3. As long as a limit pin 5 is arranged on one of the slide seats 3, the position limitation of the seat cushion 1 can be achieved. The limit pin 5 is preferably arranged on the slide seat 3 on the front side of the seat cushion 1, and the tail of the plug sleeve 4 is vertically fixed on the mounting hole 31 of the slide seat 3. The plug sleeve 4 is perpendicular to the slide seat 3, and the head of the limit pin 5 is exposed at the head of the plug sleeve 4. This arrangement makes it more convenient to pull the limit pin 5, and it is more convenient to adjust the position of the seat cushion 1. In order to further facilitate the user to pull the limit latch 5, a pull block 52 can be fixed on the head of the limit latch 5. The pull block 52 can be plum blossom-shaped, which is convenient for the user to grasp and apply force.
[0032] Key References Figure 2-4 A linear bearing 8 is provided between the slide 3 and the support frame 21, and a plurality of balls 81 are provided between the linear bearing 8 and the support frame 21, so that the slide 3 can slide smoothly on the support frame 21. The two ends of the linear bearing 8 are radially protruded with limiting steps 82 on both sides of the slide 3 to limit the slide 3 from being separated from the linear bearing 8. In addition, a transverse groove 83 is axially provided on the outer periphery of the linear bearing 8 at the position corresponding to the limiting hole 211 to make way for the limiting pin 5. The limiting pin 5 needs to pass through the mounting hole 31 and the making way groove 32 to be inserted into the limiting hole 211.
[0033] Key References Figure 6-8 The top of the tripod 22 is vertically bent to provide a connecting portion 221 that is detachably connected to the support frame 21. The connecting portion 221 is provided with a radially retractable telescopic pin 222. Both ends of the support frame 21 are provided with engaging holes 212 that are engaged with the telescopic pin 222. When the connecting portion 221 is inserted into one end of the support frame 21, the telescopic pin 222 extends out to insert into the engaging hole 212, so that the support frame 21 and the tripod 22 can be connected. After the telescopic pin 222 is retracted to exit the engaging hole 212, the connection between the tripod 22 and the support frame 21 can be disconnected.
[0034] Specifically, a telescopic hole 223 is provided on the connecting portion 221 of the tripod 22, and a flange is radially protruded from the tail of the telescopic pin 222, and the diameter of the flange is larger than the diameter of the telescopic hole 223. The tail of the telescopic pin 222 is located inside the connecting portion 221 and a reset member is abutted against the inner wall of the connecting portion 221. The reset member can be a spring or a spring sheet, etc. This embodiment adopts a V-shaped spring 224 for easy installation. One end of the V-shaped spring 224 can be slightly bent to abut against the inner wall of the connecting portion 221. The tail of the telescopic pin 222 is provided with a socket, and the other end of the V-shaped spring 224 is vertically extended and inserted into the socket to abut against the limit pin 5. The reset member pushes the telescopic bolt 222 out of the telescopic hole 223 in the original state, and the setting of the flange can prevent the telescopic bolt 222 from slipping out of the telescopic hole 223. During the process of inserting the connecting portion 221 into the support frame 21, the telescopic bolt 222 is pushed back into the telescopic hole 223 until the telescopic hole 223 is aligned with the clamping hole 212. The reset member is reset to push the telescopic bolt 222 into the clamping hole 212, thereby completing the connection between the support frame 21 and the tripod 22. Pulling the tripod 22 with force can retract the telescopic bolt 222 into the telescopic hole 223, so that the support frame 21 and the tripod 22 are disconnected, thereby making it very convenient to disassemble and assemble the support tripod 2. In addition, the head of the telescopic bolt 222 is preferably hemispherical, which can reduce the wear between the telescopic bolt 222 and the connecting portion 221, and make it easier to push the telescopic bolt 222 to retract.
[0035] Key References Figure 6-7 , the two ends of the support frame 21 are provided with limit sleeves 213 to limit the sliding stroke of the slide 3, the engaging hole 212 is located on the inner side of the limit sleeve 213, and the slide 3 is axially provided with a clearance groove 32 on one side close to the telescopic pin 222. If only one slide 3 is provided on a support frame 21, the slide 3 is provided with a clearance groove 32 on both sides; if multiple slides 3 are provided on a support frame 21, the slides 3 located on the two most sides are provided with a clearance groove 32 on one side close to the telescopic pin 222. Even when the slide 3 slides to the position abutting the limit sleeve 213, the limit pin 5 is also located in the clearance groove 32, and the slide 3 will not touch the telescopic pin 222 when sliding, so as to avoid disconnection between the tripod 22 and the support frame 21. The transverse groove 83 on the support bearing can be aligned with the limit groove, and the linear bearing 8 can also make way for the telescopic pin 222.
