[0024] Protrusions are respectively provided on the edges of both ends of the side wall of the fixed end of the adjusting tooth ring 94, and an annular groove 911 is opened on the side wall of the T-shaped fixing plate 91 corresponding to the protrusion. The adjusting tooth ring 94 is movably engaged with the annular groove 911 through the protrusion and is movably fitted on the side wall of the T-shaped fixing plate 91. A limiting groove 98 is opened on the outer wall of one side of the movable screw 95, and a limiting block 912 is fixedly connected to the corresponding limiting groove 98 on the inner wall of the through hole of the T-shaped fixing plate 91. When the movable screw 95 is movably sleeved in the through hole of the T-shaped fixing plate 91, the limiting block 912 is movably engaged in the limiting groove 98.

[0025] The adjustment assembly 8 includes a first mounting seat 81 fixedly connected to the bottom of the seat cushion plate 5 and a hydraulic rod 82 movably connected between the side walls of the first mounting seat 81, the end of the hydraulic rod 82 is fixedly connected to a horizontal bar 83, and a U-shaped rod 84 is movably penetrated at the bottom of the support column 7 on one side of the fixed end of the hydraulic rod 82, and the support arms at both ends of the U-shaped rod 84 penetrate the side walls at both ends of the horizontal bar 83, and the ends of the support arms at both ends of the U-shaped rod 84 are movably connected to second mounting seats 85, and the ends of the second mounting seats 85 are fixedly connected to the side walls of the auxiliary support plate 6; when the auxiliary support plate 6 and the backrest plate 71 are both kept vertical to the seat cushion plate 5, the hydraulic rod 82 maintains a normal relaxation state, and at this time, the end of the spring connecting rod 96 and the anti-slip pad 97 are suspended below the seat cushion plate 5 on the inner side of the roller 2.

[0026] Specifically, when a patient or a user with lower limb mobility impairment needs to move or take a bath, he sits on the cushion board 5 and starts the hydraulic rod 82. After the hydraulic rod 82 is extended, the horizontal bar 83 is used to drive the U-shaped rod 84 to move horizontally. The U-shaped rod 84 cooperates with the support column 7 to drive the backrest board 71 to deflect downward based on the crossbeam of the frame 1. At the same time, the U-shaped rod 84 drives the auxiliary support board 6 on the crossbeam at the other end of the frame 1 to deflect upward through the first mounting seat 81 at the end. At this time, the backrest board 71, the cushion board 5 and the auxiliary support board 6 are almost horizontal. The user can lie on the backrest board 71 and the cushion board 5 with a slight tilt at this time, and the hydraulic rod 82 drives the U-shaped rod 84, the backrest board 71 and the auxiliary support board 6 to stretch and deflect in a parallelogram, thereby realizing the synchronous deflection and folding control of the backrest board 71 and the auxiliary support board 6, which is convenient for using the bathing recliner to quickly switch between sitting and lying positions. After pushing the user into the narrow bathroom, the backrest board 71 and the auxiliary support board 6 are deflected and unfolded, and when the backrest board 71 deflects downward, the fixed rod 72 drives the driving The driving gear 73 rotates, and the driving gear 73 drives the adjusting gear ring 94 to rotate on the side wall of the T-shaped fixing plate 91 through the cooperation of the driven gear 93, the speed change gear 92 and the adjusting gear ring 94, thereby pushing the moving screw 95 to move horizontally in the middle threaded hole on the adjusting gear ring 94, so that the spring connecting rod 96 at the end of the moving screw 95 passes through the frame rods in the steel ring of the roller 2, and the moving screw 95 is placed horizontally in the steel ring of the roller 2 to prevent it from rotating. At the same time, the spring connecting rod 96 at the end of the moving screw 95 extends After extending to the outside of the roller 2, it contacts the inner wall of the narrow bathroom, and the anti-skid pad 97 at the end of the spring connecting rod 96 is pushed to fit the inner wall of the bathroom by moving the screw rod 95, so that the bathing recliner is automatically fixed left and right, effectively preventing the bathing recliner from slipping due to excessive movements of the user when bathing, thereby ensuring the safety of the user when bathing. When the backrest plate 71 is folded after bathing, the moving screw 95 drives the spring connecting rod 96 and the anti-skid pad 97 in the reverse direction to automatically withdraw from the inner wall of the bathroom, and release the restriction on the roller 2, which is convenient to use.

[0027] In order to further ensure the stability of the recliner when the user is taking a bath, Figure 3 , Figure 4 and Figure 7-Figure 8 As shown, this implementation provides the following technical solutions: A hollow cavity is provided at one end of the movable screw rod 95 close to the spring connecting rod 96, and one end of the spring connecting rod 96 away from the anti-slip pad 97 extends into the interior of the hollow cavity, and the end of the spring connecting rod 96 in the hollow cavity is fixedly connected with a long column piston 951, and the long column piston 951 is movably engaged between the inner wall of the hollow cavity, and a suction chamber 952 is formed between the long column piston 951 and the inner wall of the hollow cavity, and a suction channel 961 is provided inside the spring connecting rod 96, and the two ends of the suction channel 961 are respectively connected to the suction chamber 952 and the concave cavity in the anti-slip pad 97, and the end of the long column piston 951 away from the suction chamber 952 is fixedly connected with a T-rod 953, and the end of the T-rod 953 is fixedly connected with a return spring 954, and the end of the return spring 954 is fixedly connected to the inner wall of the hollow cavity.

[0028] A connecting opening 955 is respectively provided on the side walls on both sides of the hollow cavity, and a limit hook 956 is movably arranged between the inner walls on both sides of the connecting opening 955. The limit hook 956 is used to hook on the outer wall of the skeleton rod in the steel ring of the roller 2 on both sides of the moving screw 95 when the moving screw 95 is inserted into the gap of the skeleton rod in the steel ring of the roller 2. Two groups of identical winding wheels 957 are evenly spaced between the inner walls of the installation cavity in the connecting opening 955. An adjusting rope 958 is fixedly connected to the end of the limiting hook 956 away from the hook head. After the adjusting rope 958 is passed through the outer wall of the winding wheel 957 in an S shape, the end is fixedly connected to the outer wall of the cross bar end of the T-bar 953.

[0029] When the port of the exhaust channel 961 close to one end of the long column piston 951 is close to the inner wall of the end of the exhaust chamber 952, the return spring 954 maintains a normal relaxation state. At this time, the limit hook 956 is horizontally received in the port of the connecting port 955.

[0030] Specifically, when the backrest board 71 deflects downward, the movable screw 95, driven by the adjusting gear ring 94, pushes the anti-skid pad 97 at the end of the spring connecting rod 96 to move and fit into contact with the inner wall of the bathroom. As the backrest board 71 continues to deflect downward, the movable screw 95 uses the spring connecting rod 96 to push the anti-skid pad 97 to squeeze the inner wall of the bathroom. The inner wall of the bathroom in turn pushes the anti-skid pad 97 to promote the spring connecting rod 96 to move into the hollow cavity of the movable screw 95. When the spring connecting rod 96 moves into the movable screw 95 The long column piston 951 and the T-shaped rod 953 are pushed to squeeze the return spring 954. When the long column piston 951 slides in the hollow cavity, the air in the space formed by the concave cavity of the anti-skid pad 97 and the inner wall of the bathroom is sucked into the suction chamber 952 at the end of the long column piston 951 by using the suction channel 961 in the spring connecting rod 96, so as to form a negative pressure environment in the concave cavity of the anti-skid pad 97, thereby enhancing the support stability of the bathing recliner. When the T-shaped rod 953 squeezes the return spring 954 to move, The adjusting rope 958 is driven to move, and the adjusting rope 958 is passed through the outer wall of the winding wheel 957 and then pulled on one end of the limit hook 956, so that it is deflected between the inner walls of the connecting port 955 on both sides of the installation cavity, so that the hook head of the limit hook 956 is deflected and moved to the outside of the connecting port 955, so that it moves with the moving screw 95 to press the skeleton rod in the steel ring of the roller 2, so that the hook head of the limit hook 956 selectively hooks the skeleton rod in the steel ring of the roller 2, and the return spring 9 54's elastic support and the negative pressure reaction force of the groove in the anti-slip pad 97, the frame rod in the steel ring of the roller 2 is pulled by the adjusting rope 958 in cooperation with the limiting hook 956, so as to further ensure the stability of the roller 2 when it is stationary, and the elastic tensioning of the adjusting rope 958 and the vibration buffering of the reset spring 954 are utilized to reduce the deformation and destructive stress of the frame rod in the steel ring of the roller 2 caused by the vibration of the frame 1 caused by the action during bathing, so as to prevent the frame rod in the steel ring of the roller 2 from excessive deformation and damage.
