[0031] Elderly or infirm people need to use a bathing chair when taking a bath. Some existing rotatable bathing chairs include a foot frame assembly 100, a seat assembly 200 and a rotating mechanism 300. The rotating structure generally adopts a rotating structure similar to a dining table turntable, including an inner ring and an outer ring, wherein the inner ring is fixed to the seat assembly 200, and the outer ring is fixed to the foot frame assembly 100. Ball bearings are arranged between the outer circumferential wall of the inner ring and the inner circumferential wall of the outer ring, so as to meet the requirement of smooth rotation. However, in actual application, when a user sits on the seat assembly 200, a large downward pressure will be formed, so that the inner ring is pressed against the upper part of the foot frame assembly 100 or the outer ring is pressed against the bottom surface of the seat assembly 200, which increases the friction resistance, reduces the smoothness of rotation, and is inconvenient to use.

[0032] Reference Figures 1 to 6 , which is a rotatable bathing chair according to an embodiment of the utility model, comprises a foot frame assembly 100 , a seat assembly 200 and a rotating mechanism 300 . The seat assembly 200 is located above the foot frame assembly 100; the rotating mechanism 300 is arranged between the foot frame assembly 100 and the seat assembly 200, the rotating mechanism 300 includes a rotating seat 310, a rotating shaft 320, an upper limit member 330 and a first plane support assembly 340, the upper limit member 330 is connected to the upper end of the rotating shaft 320, the upper limit member 330 is arranged on the seat assembly 200, the rotating seat 310 is arranged on the foot frame assembly 100, the rotating shaft 320 is passed through the rotating seat 310 in the up and down directions, the first plane support assembly 340 is arranged between the upper limit member 330 and the rotating seat 310, the first plane support assembly 340 includes a first upper ring 341, a first rolling member 342 and a first lower ring 343 arranged vertically, the first upper ring 341 abuts the upper limit member 330, the first lower ring 343 abuts the rotating seat 310, and the first rolling member 342 is arranged between the first upper ring 341 and the first lower ring 343.

[0033] By setting a first planar support assembly 340 between the upper limit positioning member 330 and the rotating seat 310, the first planar support assembly 340 provides an axial force to support the position of the upper limit positioning member 330 and the chair back assembly relative to the rotating seat 310 and the foot frame assembly 100, and reduces the contact force between the upper limit positioning member 330 and the upper end of the rotating seat 310, so that when the chair back assembly rotates, the friction between the upper limit positioning member 330 and the upper end of the rotating seat 310 is reduced, and the friction is reduced by the rolling connection between the first upper ring 341 and the first lower ring 343 through the first rolling member 342, so that the chair back assembly rotates smoothly and the user experience is improved.

[0034] It is understandable that the first planar support assembly 340 can reduce part of the contact force between the upper limit member 330 and the rotating seat 310 , or can reduce the entire contact force between the upper limit member 330 and the rotating seat 310 .

[0035] In an embodiment, the upper limit positioning member 330 is spaced apart from the upper end of the rotating seat 310 so that there is no direct contact between the upper limit positioning member 330 and the rotating seat 310. The rotating seat 310 provides an axial force to support the chair back assembly via the first planar support assembly 340, thereby reducing the total contact force between the upper limit positioning member 330 and the rotating seat 310. The chair back assembly rotates more smoothly and with less noise, further improving the user experience.

[0036] In the embodiment, an upper receiving hole 311 is provided at the upper part of the rotating seat 310, and the hole axis of the upper receiving hole 311 is arranged along the up-down direction. The first planar support assembly 340 is arranged in the upper receiving hole 311, and the first lower ring 343 abuts against the hole bottom of the upper receiving hole 311. The depth of the upper receiving hole 311 is smaller than the axial dimension of the first planar support assembly 340. The upper receiving hole 311 is provided to accommodate part of the first planar support assembly 340, so that the axial structure of the rotating mechanism 300 is more compact; and the axial dimension of the first planar support assembly 340 is larger than the depth of the upper receiving hole 311, so that the upper limit member 330 and the upper end of the rotating seat 310 can be arranged at intervals. The hole wall of the upper receiving hole 311 also has the function of a protective cover of the first planar support assembly 340, so as to avoid the risk of water or detergent splashing into the first planar support assembly 340 during bathing and affecting the service life of the first planar support assembly 340, so as to make the bathing chair more durable.

[0037] Specifically, the first plane support component 340 is a thrust ball bearing in a plane thrust bearing, which has a relatively good use effect and can be directly purchased as a standard part. The first rolling element 342 is a ball. It is conceivable that the first plane support component 340 can also be other structures that can provide axial support force, such as thrust spherical roller bearings, tapered roller bearings, thrust roller bearings, four-point contact ball bearings, thrust cylindrical roller bearings, thrust needle roller bearings or thrust tapered roller bearings, etc., or other structures that can provide axial thrust, and those skilled in the art can make specific configurations according to actual needs.

[0038] Specifically, the outer peripheral wall of the first lower ring 343 is tightly matched with the lower end hole wall of the upper accommodating hole 311, so that the first lower ring 343 can be installed and fixed on the upper accommodating hole 311. The upper accommodating hole 311 is provided with a reamer at one end close to the hole opening. The upper accommodating hole 311 is in a stepped hole shape, so that the outer peripheral wall of the first upper ring 341 and the hole wall of the reamer of the upper accommodating hole 311 are spaced apart, and the inner hole of the first upper ring 341 is tightly matched with the rotating shaft 320. The above structure facilitates the first planar support assembly 340 to be installed in the upper accommodating hole 311, and can radially limit the rotating shaft 320, so that the rotating shaft 320 can rotate relative to the rotating seat.

[0039] It is conceivable that, in some embodiments, the lower portion of the first planar support assembly 340 may also be directly placed on the upper end surface of the rotating seat 310 to allow the upper limit member 330 to be spaced apart from the upper end of the rotating seat 310. Those skilled in the art may configure the configuration according to actual needs.

[0040] Specifically, the upper limit member 330 is a plate, and the rotating shaft 320 and the upper limit member 330 are an integral part. It is conceivable that the upper limit member 330 and the rotating shaft 320 can also be two parts assembled with each other, and the upper limit member 330 can also be a nut threadedly connected to the upper end of the rotating shaft 320.

[0041] In an embodiment, the rotating mechanism 300 also includes a lower limit member 350 and a second planar support assembly 360, the lower limit member 350 is located below the rotating seat 310 and is connected to the rotating shaft 320, the second planar support assembly 360 is arranged between the lower limit member 350 and the rotating seat 310, the second planar support assembly 360 includes a second upper ring 361, a second rolling member 362 and a second lower ring 363 arranged vertically, the second upper ring 361 abuts the rotating seat 310, the second lower ring 363 abuts the lower limit member 350, and the second rolling member 362 is arranged between the second upper ring 361 and the second lower ring 363. The upper limit member 330 and the lower limit member 350 jointly limit the vertical position of the rotating shaft 320 relative to the rotating seat 310, and usually, the upper limit member 330 and the lower limit member 350 clamp the rotating seat 310 so that the seat assembly 200 does not shake up and down. Therefore, there is usually a large friction between the lower limit member 350 and the lower end of the rotating seat 310, and a relatively large force is required to rotate the backrest assembly, and a large noise may be generated between the two, affecting the user experience. Therefore, a second plane support assembly 360 is further provided to reduce the contact force between the lower limit member 350 and the lower end of the rotating seat 310, and the friction and noise of the second plane support assembly 360 are relatively small when used, so that the backrest assembly can be rotated with a relatively small force, and the noise generated when the backrest assembly is rotated is further reduced, thereby improving the user experience of the bathing chair.

[0042] It is understandable that the second planar support assembly 360 can reduce part of the contact force between the lower stopper 350 and the rotating seat 310 , or can reduce the entire contact force therebetween.

[0043] Specifically, the upper limit member 330 is connected to the chair back assembly by screw locking, so that the upper limit member 330 is fixed to the chair back assembly. It is conceivable that the upper limit member 330 can also be connected to the chair back assembly by welding, or by riveting.

[0044] Specifically, the chair back assembly includes a seat cushion, armrests connected to opposite sides of the seat cushion, and a chair back connected to the rear side of the seat cushion. The seat cushion is provided with a plurality of drainage holes to conveniently and quickly drain the accumulated water on the seat cushion.

[0045] In an embodiment, the lower limit member 350 is spaced apart from the lower end of the rotating seat 310 so that the lower limit member 350 is no longer in direct contact with the lower end of the rotating seat 310, thereby reducing the total contact force between the lower limit member 350 and the lower end of the rotating seat 310. Since the friction and noise of the second planar support assembly 360 are relatively small when in use, the force required to rotate the chair back assembly is minimized, and the noise when the chair back assembly is rotated is minimized.

[0046] In the embodiment, a lower receiving hole 312 is provided at the lower part of the rotating seat 310, and the hole axis of the lower receiving hole 312 is arranged along the up-down direction. The second planar support assembly 360 is arranged in the lower receiving hole 312, and the second upper ring 361 abuts against the bottom of the lower receiving hole 312. The depth of the lower receiving hole 312 is smaller than the axial dimension of the second planar support assembly 360. The lower receiving hole 312 is provided to accommodate part of the second planar support assembly 360, so that the axial structure of the rotating mechanism 300 is more compact; and the axial dimension of the second planar support assembly 360 is larger than the depth of the lower receiving hole 312, so that the lower stopper 350 and the lower end of the rotating seat 310 can be arranged at intervals. The hole wall of the lower receiving hole 312 also has the function of a protective cover for the second planar support assembly 360, so as to avoid the risk of water or detergent splashing into the second planar support assembly 360 during bathing and affecting the service life of the second planar support assembly 360, so as to make the bathing chair more durable.

[0047] Specifically, the second plane support component 360 is a thrust ball bearing in a plane thrust bearing, which has a relatively good use effect and can be directly purchased as a standard part. The second rolling element 362 is a ball. It is conceivable that the second plane support component 360 can also be other structures that can provide axial support force, such as thrust spherical roller bearings, tapered roller bearings, thrust roller bearings, four-point contact ball bearings, thrust cylindrical roller bearings, thrust needle roller bearings or thrust tapered roller bearings, etc., or other structures that can provide axial thrust, and those skilled in the art can make specific configurations according to actual needs.

[0048] Specifically, the outer peripheral wall of the second upper ring 361 is tightly matched with the upper end hole wall of the lower accommodating hole 312, so that the second upper ring 361 can be installed and fixed to the lower accommodating hole 312. The lower accommodating hole 312 is provided with a hole expansion part at one end close to the hole mouth. The lower accommodating hole 312 is in a stepped hole shape, so that the outer peripheral wall of the second lower ring 363 is spaced from the hole wall of the hole expansion part of the lower accommodating hole 312, and the inner hole of the second lower ring 363 is tightly matched with the rotating shaft 320. The above structure facilitates the second planar support assembly 360 to be installed in the lower accommodating hole 312, and can radially limit the rotating shaft 320, so that the rotating shaft 320 can rotate relative to the rotating seat.

[0049] It is conceivable that, in some embodiments, the upper portion of the second planar support assembly 360 may also directly abut against the lower end surface of the rotating seat 310 to allow the lower limit member 350 to be spaced apart from the lower end of the rotating seat 310. Those skilled in the art may configure the configuration according to actual needs.

[0050] Specifically, the lower limit member 350 is a nut, which is threadedly connected to the lower part of the rotating shaft 320. The upper limit member 330 and the lower limit member 350 clamp the rotating seat 310 through the first plane support assembly 340 and the second plane support assembly 360, thereby firmly limiting the upper and lower positions of the seat assembly 200 and preventing it from shaking. It is conceivable that the lower limit member 350 can also be a retaining ring or other limiting structures, and those skilled in the art can make specific configurations according to actual needs.

[0051] In the embodiment, the rotating mechanism 300 further includes a first bayonet 370 and a first elastic member 380. At least two locking grooves 313 are arranged on the outer side of the rotating seat 310 around the rotation axis of the rotating shaft 320. The first bayonet 370 is slidably arranged on the upper limit member 330 and can be inserted into or pulled out of the locking groove 313. The first elastic member 380 is arranged between the first bayonet 370 and the upper limit member 330 and can drive the first bayonet 370 to press against the outer side of the rotating seat 310. The first bayonet 370 and the first elastic member 380 are arranged. When the first bayonet 370 is inserted into the locking groove 313 of the rotating seat 310, the first bayonet 370 limits the rotation of the upper limit member 330 relative to the rotating seat 310, so that the seat assembly 200 cannot rotate. When the seat assembly 200 needs to be rotated, the user can pull the first latch 370 out of the locking slot 313, and then rotate the direction of the backrest assembly. During this period, after releasing the first latch 370, the first elastic member 380 will drive the first latch 370 to press against the outer side of the rotating seat 310 until the first latch 370 is inserted into another locking slot 313, and the direction of the backrest assembly is automatically locked. With the above structure, the backrest assembly will not rotate at will, and can only rotate when the first latch 370 is pulled out, and the gear position can be automatically locked after rotation. The backrest assembly can rotate or be fixed in position, with a simple structure and good safety.

[0052] Specifically, four positioning grooves 313 are evenly distributed around the outer side of the rotating seat 310, the first elastic member 380 is a spring, and the first bayonet 370 is provided with a blocking piece, one end of the spring abuts against the blocking piece, and the other end of the spring abuts against the upper limit member 330, thereby applying an elastic force to the first bayonet 370. It is conceivable that two, three or more positioning grooves 313 may be provided around the outer side of the rotating seat 310, and the first elastic member 380 may also be a spring sheet, a torsion spring or a rubber block, etc., and those skilled in the art may make specific configurations according to actual needs.

[0053] Specifically, a first handle 390 is provided at the outer end of the first bayonet 370 , so that the user can pull out the first bayonet 370 through the first handle 390 . The structure is simple and easy to implement.

[0054] Specifically, the moving direction of the first bayonet 370 is along the radial direction of the rotating seat 310, so that when the first bayonet 370 is inserted into the locking groove 313, the positioning effect of the upper limit member 330 and the rotating seat 310 is relatively good. It is conceivable that the moving direction of the first bayonet 370 can also be inclined relative to the radial direction of the rotating seat 310, and those skilled in the art can make specific configurations according to actual needs.

[0055] In the embodiment, the tripod assembly 100 includes a tripod body 110, a sliding platform 120 and a positioning mechanism 130. The tripod body 110 is provided with two guide tubes 111. The sliding platform 120 is provided with a guide assembly that is slidably matched with the guide tubes 111 in a one-to-one manner. The guide assembly includes a sliding sleeve 121 and two sliding matching parts 122. The two sliding matching parts 122 are spaced apart in the sliding sleeve 121. The sliding matching parts 122 are provided with through holes that are slidably matched with the guide tubes 111. A spacing area is formed between two adjacent sliding matching parts 122. The positioning mechanism 130 includes a second pin 131 and two positioning holes 132. The positioning holes 132 are provided on the guide tube 111. The second pin 131 is slidably provided on the sliding sleeve 121 and is located in the spacing area. The second pin 131 can be inserted into or pulled out of the positioning hole 132 to lock or unlock the position of the sliding platform 120 relative to the tripod body 110. The rotating mechanism 300 is connected to the sliding platform 120.

[0056] The two sliding fittings 122 are arranged at intervals in the sliding sleeve 121, so that the sliding platform 120 can slide more smoothly relative to the tripod body 110; when the second pin 131 is inserted into the positioning hole 132, the sliding platform 120 cannot slide relative to the tripod body 110, thereby fixing the position of the seat assembly 200 relative to the tripod assembly 100; when the second pin 131 is pulled out of the positioning hole 132, the position of the sliding platform 120 and the seat assembly 200 can be moved, thereby meeting different usage requirements and having better safety.

[0057] Specifically, a mounting plate is disposed around the outer side of the rotating seat 310, and the mounting plate is threadedly connected to the sliding table 120 by screws, so as to be installed and fixed to the sliding table 120. It is conceivable that the rotating seat 310 can also be connected to the sliding table 120 by welding, or fixed to the sliding table 120 by riveting.

[0058] Specifically, the two sliding sleeves 121 are located at opposite ends of the sliding platform 120 , and the two sliding sleeves 121 are connected by a reinforcing rod, so that the structure of the sliding platform 120 is relatively firm.

[0059] In the embodiment, the sliding fitting 122 is a linear bearing, and the guide assembly is provided with two sliding fittings 122, and the two sliding fittings 122 are respectively provided at the opposite ends of the sliding sleeve 121. By respectively providing the two sliding fittings 122 at the opposite ends of the sliding sleeve 121, it is not easy for the sliding platform 120 to deviate to the opposite ends of the guide tube 111, and the stability of the seat assembly 200 is better when sliding; the sliding fitting 122 adopts a linear bearing, and the sliding of the seat assembly 200 is relatively labor-saving and noise-reducing. It is conceivable that the sliding fitting 122 may not be provided at the opposite ends of the sliding sleeve 121, and the sliding fitting 122 may also adopt other structures, such as nylon sleeves, etc., which also have a good sliding effect.

[0060] Specifically, the sliding fitting 122 is fixed in the sliding sleeve 121 through a retaining spring. It is understandable that the sliding fitting 122 can also be fixed in the sliding sleeve 121 through a method such as screw locking.

[0061] Specifically, the tripod body 110 is provided with two guide tubes 111, so that the sliding platform 120 can slide relatively smoothly and simplify the structure of the tripod assembly 100. It is conceivable that the tripod body 110 can also be provided with only one guide tube 111, in which case the guide tube 111 can be a flat elliptical tube, which can also make the seat assembly 200 relatively stable; or the tripod body 110 can also be provided with three or more guide tubes 111, and those skilled in the art can make specific configurations according to actual needs.

[0062] Specifically, the positioning mechanism 130 includes a second bayonet 131 and two positioning holes 132. The guide tube 111 is provided with two positioning holes 132 arranged at intervals along the length direction, so that the sliding platform 120 can be positioned at different positions relative to the tripod body 110 to meet different usage requirements. It is conceivable that the positioning mechanism 130 may also include one or more than two positioning holes 132, so that the sliding platform 120 can be positioned at a specified position through the second bayonet 131; the second bayonet 131 may also be provided with two or more to improve the firmness of the sliding platform 120 when it is positioned.

[0063] In the embodiment, the positioning mechanism 130 further includes a second elastic member 133, which is disposed between the second bayonet 131 and the sliding sleeve 121 and can drive the second bayonet 131 to press against the outer side of the guide tube 111. After the second bayonet 131 is pulled out of the positioning hole 132, the sliding platform 120 is moved along the guide tube 111 to adjust the position of the seat assembly 200, during which the second bayonet 131 can be released. Under the action of the second elastic member 133, the second bayonet 131 continues to press against the outer side of the guide tube 111. When the sliding platform 120 slides until the second bayonet 131 passes through the positioning hole 132, the second elastic member 133 automatically drives the second bayonet 131 to insert into the positioning hole 132, thereby realizing the automatic locking of the sliding platform 120 and the seat assembly 200, and facilitating the seat assembly 200 to form a similar position gear adjustment function, with a simple structure and good safety.

[0064] Specifically, the second elastic member 133 is a spring, the sliding sleeve 121 is provided with a bayonet guide tube 134 in the radial direction, a closing structure is provided at the outer end of the bayonet guide tube 134, the second bayonet 131 includes a connecting shaft and a plug head with an outer diameter larger than that of the connecting shaft, the second bayonet 131 is penetrated by the bayonet guide tube 134, the closing structure allows the connecting shaft to pass through but restricts the plug head from passing through, the spring is sleeved on the outer side of the connecting shaft and is located in the bayonet guide tube 134, one end of the spring abuts against the closing structure, and the other end of the spring abuts against the plug head, thereby providing an elastic force toward the guide tube 111 to the second bayonet 131. The bayonet guide tube 134 is provided to facilitate the relatively accurate sliding direction of the second bayonet 131, and when the second bayonet 131 is pulled out of the positioning hole 132, the structure of the second bayonet 131 limits the pull-out range of the second bayonet 131, thereby preventing the second bayonet 131 from accidentally detaching from the bayonet guide tube 134, and having good stability in use.

[0065] Specifically, the second handle 140 is connected to one end of the second bayonet 131 away from the guide tube 111. The second handle 140 can facilitate pulling out the second bayonet 131 and can also limit the position of the second bayonet 131 for easy use. The second handle 140 can be connected to the end of the second bayonet 131 by threaded connection or by welding.

[0066] Specifically, the sliding sleeve is provided with a mounting hole 123, the axis of the mounting hole 123 is coaxial with the central axis of the bayonet guide tube 134, and the second bayonet 131 can be installed in the bayonet guide tube 134 through the mounting hole 123. After the spring is arranged on the outer surface of the second bayonet 131, the second bayonet 131 penetrates into the bayonet guide tube 134 from the mounting hole 123, and the connecting shaft of the second bayonet 131 extends out of the closing structure. At this time, the second handle 140 is installed on the end of the connecting shaft to limit the movement stroke of the second pull pin.

[0067] Specifically, an extension section is provided on the inner side of the bayonet guide tube 134 toward the sliding sleeve 121 , so as to further improve the moving track accuracy of the second bayonet 131 .

[0068] Specifically, both ends of the guide tube 111 are provided with limiters, which are used to limit the sliding range of the sliding platform 120. The limiters are screws, which are threadedly connected to the guide tube 111, and the heads of the screws can stop the sliding fittings 122, thereby limiting the maximum sliding range of the sliding platform 120.

[0069] In the embodiment, the leg frame body 110 includes a connecting frame and four legs 150. The connecting frame is provided with a plug-in rod, and the legs 150 are provided with plug-in holes for plugging with the plug-in rod. The legs 150 are detachably plugged into the connecting frame. When the bathing chair needs to be transported or stored, the four legs 150 can be detached from the connecting frame, thereby reducing the storage space of the bathing chair and facilitating storage and transportation.

[0070] Furthermore, the plug-in rod is provided with a spring pin, and the support leg 150 is provided with a plurality of spring pin holes arranged along the length direction of the plug-in hole. The spring pin is inserted in one of the gear holes. The spring pin can be switched and inserted in different gear holes to adjust the overall height of the bathing chair, making the bathing chair more flexible to use.

[0071] Specifically, when the height of the bathing chair needs to be adjusted, the spring pin is pressed out of the gear hole, and the support leg 150 can be pulled relative to the connecting frame until the spring pin is automatically inserted into another gear hole, and the height gear adjustment of the bathing chair is achieved.

[0072] Specifically, the support leg 150 is provided with five gear holes, and the bathing chair can be adjusted to five gears in height. It is conceivable that the support leg 150 can also be provided with two, three or more gear holes, and those skilled in the art can configure the specific configuration according to actual needs. The spring pin is a common structure in the market and will not be described in detail here.
