[0047] like Figure 1-8As shown, as a first embodiment of the present invention, a children's sensory integration turntable is provided, including a base unit 1 and a turntable unit 2. The base unit 1 includes a base structure 11 for being placed on a support surface such as the ground or the floor, and a mounting structure 12 arranged on the upper part of the base structure 11, and a supporting interface 10 for abutting against the support surface is formed in the circumferential direction at the lower part of the base structure 11. The mounting structure 12 includes a mounting channel 110 that passes through the base structure 11, a mounting support 121 located in the mounting channel 110, and a connecting channel 120 that is arranged along the center of the mounting support 121 and passes through the base structure 11. The turntable unit 2 includes a bearing structure 21 and a connecting structure 22 connected to the lower part of the bearing structure 21. The connecting structure 22 includes a supporting member 221 wrapped by the lower part of the bearing structure 21 and a connecting member 222 connected to the supporting member 221. The lower part of the connecting member 222 is set as a rotating shaft 2222, which is sleeved in the connecting channel 120 and connected to the base unit 1, thereby driving the turntable unit 2 to rotate relative to the base unit 1.The children's sensory integration turntable of this embodiment includes a base unit 1 and a turntable unit 2. The turntable unit 2 includes a bearing structure 21 and a connecting structure 22 connected to the lower part of the bearing structure 21. The bearing structure 21 and the connecting structure 22 are processed and connected as an integrated structure during production. The connection is stable and reliable, and the supporting member 221 of the connecting structure 22 is wrapped by the lower part of the bearing structure 21, so that the supporting member 221 of the connecting structure 22 is firmly wrapped and fixed in the lower part of the bearing structure 21, and the connecting structure 22 will not fall off from the bearing structure 21, thereby greatly improving the connection structure 22. The stability and reliability of the connection between the turntable unit 222 and the bearing structure 21 make the children's sensory training safer and more suitable for children to carry out sensory training. The connecting member 222 and the supporting member 221 are an integrated structure, and no additional screws are required for connection, which simplifies the structure. After the turntable unit 2 is connected to the base unit 1 through the rotating shaft 2222, it is arranged at an angle with the support interface 10 of the base unit 1, and is rotatable relative to the base unit 1 along its axial direction through the rotating shaft 2222, so that the turntable unit 2 has a height difference during rotation, and the child rides on the turntable unit 2 to rotate. When the child sits on the carrying structure 21, he or she can not only feel the horizontal rotation, but also feel the rising and falling, which makes the sensory stimulation to the child more comprehensive, increases the fun of playing, and can stimulate the child's interest in sensory training; the upper part of the carrying structure 21 is provided with a carrying part 2111 with an arc-shaped surface for the human body's buttocks, legs or other toys to abut against, so that the child can sit on the carrying part 2111 and rotate, or place various toys on the carrying part 2111 to rotate and play. The carrying part 2111 is set as an arc surface, which is more in line with the human body structure. When the child sits on the carrying part 2111, the carrying part 2111 is more suitable for the human body structure. The turntable unit 2 has better stability and is not easy to fly out of the turntable unit 2 under the centrifugal force of rotation, which further improves the safety of children's sensory training; the support interface 10 is arranged along the circumferential direction of the lower part of the base structure 11, and can support the pressure applied at various angles during the rotation of the turntable unit 2 in a 360° direction, and the outer surface of the base structure 11 is arranged in an arc shape from the top to the bottom, so that during the rotation of the turntable unit 2, the force on each part of the base unit 1 is relatively uniform, so that the structure is stable and strong, not easy to be damaged, which further improves the safety of children's sensory training.

[0048] like Figure 2As shown, in some specific embodiments, the bearing structure 21 includes a bearing plate 211 and a gripping member 2112 arranged on the bearing plate 211 for gripping when driving the bearing structure 21 to rotate. The bearing portion 2111 is configured as a panel structure formed by the upper surface of the bearing plate 211 along the circumferential direction. When a child rides on the bearing portion 2111 and rotates, the gripping member 2112 can be grasped by hand to further prevent the child from flying out of the turntable unit 2 under the action of the centrifugal force of the rotation, thereby further improving the safety of the child during sensory training. The gripping member 2112 is composed of a partial external flange of the bearing portion 2111, which simplifies the structure. In other embodiments, the gripping member 2112 can also be configured as an independent structure connected to the bearing portion 2111, which can also be used for gripping during the rotation of the child.

[0049] like Figure 3 As shown, in some specific embodiments, a plurality of first support members 212 for providing support force are provided at the lower part of the bearing plate 211. The first support members 212 are arranged at intervals and linearly along the lower surface of the bearing plate 211 and are arranged in a block-shaped structure protruding from the bottom end surface of the bearing plate 211. The bearing structure 21 is made of plastic material and is formed by injection molding, blow molding and other production processes to facilitate mass production. The first support members 212 are used to strengthen the structural strength of the bearing plate 211 and improve the stability and load-bearing capacity of the bearing structure 21 for supporting children. In other embodiments, the first support members 212 may not be provided, and the bearing structure 21 may also be made of other materials such as metal and wood.

[0050] In some specific embodiments, a plurality of first support members 212 are provided, wherein a portion of the first support members 212 are provided as strip structures and are arranged in a clockwise direction with the center of the supporting plate 211, so as to provide direct and strong support for the pressures at various angles applied to the supporting plate 211 by the child when sitting on the supporting portion 2111, thereby preventing the supporting plate 211 from breaking. One of the first support members 212 is provided as a circular structure and is arranged coaxially with the connecting shaft 2221, and the radius is set to be greater than the radius of the connecting shaft 2221. A portion of the first support members 212 with strip structures is arranged on the outer side of the first support member 212 with circular structure, and one end is combined with the external flange 2113, and the other end is combined with the first support member 212 with circular structure. Another portion of the first support members 212 with strip structures is arranged on the inner side of the first support member 212 with circular structure, and one end is combined with the first limiting member 214, and the other end is combined with the first support member 212 with circular structure, so that the structure of the supporting structure 21 is more stable and strong. In other embodiments, the first support member 212 may also be configured as a curved structure or other shaped structures, which can be used to enhance the structural strength of the supporting plate 211 .

[0051] like Figure 3 ,7 -8, in some specific embodiments, the supporting plate 211 has an external flange 2113, and the external flange 2113 is arranged to be a boss distributed along the outer circumference of the supporting plate 211 and extending from the upper surface of the supporting portion 2111 toward the bottom. When the turntable unit 2 rotates relative to the base unit 1 through the rotating shaft 2222, the curved surface from the highest point to the center point of the supporting portion 2111 is arranged at an M angle with the support interface 10, which is consistent with the human body structure. When a child sits on the supporting portion 2111, the calf can be pressed against the external flange 2113, and the calf is in surface contact with the external flange 2113, so as to avoid scratching the legs and improve the riding comfort of the child. The end of the first support member 212 is combined with the inner surface of a portion of the external flange of the supporting plate 211, which can strengthen the structural strength of the external flange 2113, improve the stability and load-bearing capacity of the external flange 2113 in supporting children, and prevent the external flange 2113 from breaking. That is, the structural strength of the outer circumference of the supporting plate 211 is strengthened, and the outer circumference structure of the supporting plate 211 is prevented from breaking, thereby further improving the strength of the overall structure of the supporting structure 21.

[0052] In some specific embodiments, the connection structure 22 is made of metal materials such as iron and aluminum, and has a stable and strong structure, so that the overall structure of the turntable unit 2 has strong stability and load-bearing capacity. Figure 7 , 8 As shown, the upper part of the connecting structure 22 is completely covered by the lower structure of the bearing structure 21, and the upper part of the connecting structure 22 can be fully wrapped and fixed, thereby improving the stability of the connection between the connecting structure 22 and the bearing structure 21. In other embodiments, the upper part of the connecting structure 22 can also be configured to be partially covered by the lower structure of the bearing structure 21, and the upper part of the connecting structure 22 can also be firmly wrapped and fixed in the lower structure of the bearing structure 21.

[0053] like Figure 4 As shown, in some specific embodiments, a wrapping area 213 is provided at the lower portion of the bearing structure 21, and the supporting member 221 is located in the wrapping area 213 and covered by the outer end surface of the bearing structure 21, so that the supporting member 221 can be axially limited in the bearing structure 21 along the rotating shaft 2222, thereby preventing the connecting structure 22 from moving relative to the bearing structure 21 along the rotating shaft 2222 axially, and preventing the connecting structure 22 from falling off from the bearing structure 21.

[0054] like Figure 4As shown, in some specific embodiments, the connecting member 222 includes a connecting shaft 2221 connected to the supporting member 221, the lower portion of the connecting shaft 2221 forms the rotating shaft 2222, and the upper portion of the connecting shaft 2221 protrudes outward and is provided with a connecting plate 2223 arranged along the length direction of the connecting shaft 2221, and the upper portion of the connecting shaft 2221 and a partial structure of the connecting plate 2223 are located in the wrapping area 213 and are covered by the outer end surface of the supporting structure 21, so as to limit the connecting plate 2223 in the circumferential direction of the rotating shaft 2222 within the supporting structure 21, thereby avoiding the circumferential movement of the connecting structure 22 relative to the supporting structure 21 along the rotating shaft 2222, and preventing the connecting structure 22 from rotating relative to the supporting structure 21.

[0055] In some specific embodiments, the support member 221 is configured as a panel structure corresponding to the arrangement direction of the bearing portion 2111, and has a larger contact area with the bearing structure 21, which can better prevent the connection structure 22 from moving relative to the bearing structure 21 along the axial direction of the rotation axis 2222, and prevent the connection structure 22 from falling off the bearing structure 21. In this embodiment, the support member 221 is configured as a disc structure with a simple structure. In other embodiments, it can also be configured as a square disc structure, a five-pointed star structure, or other shaped structures. Several connecting plates 2223 are arranged at intervals along the circumferential direction of the connecting axis 2221, and have a larger contact area with the bearing structure 21, which can better prevent the connection structure 22 from moving relative to the bearing structure 21 along the circumferential direction of the rotation axis 2222, and prevent the connection structure 22 from rotating relative to the bearing structure 21. Each connecting plate 2223 is arranged along the radial direction of the connecting shaft 2221 and is vertically connected to the lower surface of the supporting member 221, so that the connecting plates 2223 form a triangular supporting structure between the connecting shaft 2221 and the supporting member 221, which can enhance the stability and load-bearing capacity of the supporting member 221 structure, thereby enhancing the stability and load-bearing capacity of the overall structure of the turntable unit 2, and is more conducive to preventing the connecting structure 22 from moving relative to the bearing structure 21 along the circumferential direction of the rotating shaft 2222. Of course, in other embodiments, the supporting member 221 can also be set as a rod-shaped structure or other structures, and only one connecting plate 2223 can be set, and the connecting plate 2223 can also be arranged at an inclined angle to the radial direction of the connecting shaft 2221 or at an inclined angle to the lower surface of the supporting member 221. These embodiments all achieve mutual positioning between the connecting structure 22 and the bearing structure 21.

[0056] like Figure 3 As shown, in some specific embodiments, the bearing structure 21 further includes a first stopper 214 protruding from the lower surface of the bearing plate 211 and arranged corresponding to the upper portion of the connecting shaft 2221, and a second stopper 215 protruding from the lower surface of the bearing plate 211 and arranged corresponding to the connecting plate 2223. Figure 7 , 8As shown, the wrapping area 213 includes a first area 2131 disposed in the lower structure of the carrier plate 211, a second area 2132 disposed in the first stopper 214, and a third area 2133 disposed in the second stopper 215. The support member 221 is wrapped in the first area 2131 and covered by the outer end surface of the carrier plate 211, the top surface of the support member 221 abuts or combines with the top surface of the first area 2131, the bottom surface of the support member 221 abuts or combines with the bottom surface of the first area 2131, and the peripheral side surface of the support member 221 abuts or combines with the peripheral side surface of the first area 2131, so that the support member 221 is firmly wrapped and fixed in the first area 2131, and the support member 221 is prevented from axially or radially moving relative to the carrier plate 211. Part of the structure of the upper portion of the connecting shaft 2221 is wrapped in the second region 2132 and covered by the outer end surface of the first stopper 214. The circumferential side surface of the upper portion of the connecting shaft 2221 abuts or combines with the circumferential side surface of the second region 2132, thereby firmly wrapping and fixing the upper portion of the connecting shaft 2221 in the second region 2132, and preventing the upper portion of the connecting shaft 2221 from moving radially relative to the first stopper 214. Part of the structure of the connecting plate 2223 is wrapped in the third region 2133 and covered by the outer end surface of the second stopper 215. One side surface of the connecting plate 2223 abuts or combines with one side surface of the third region 2133, the other side surface of the connecting plate 2223 abuts or combines with the other side surface of the third region 2133, and the end surface of the connecting plate 2223 abuts or combines with the end surface of the third region 2133, thereby firmly wrapping and fixing the connecting plate 2223 in the third region 2133, and preventing the connecting plate 2223 from moving circumferentially or radially relative to the second stopper 215. In other embodiments, the entire structure of the upper portion of the connecting shaft 2221 and the connecting plate 2223 may be located in the wrapping area 213 and covered by the outer end surface of the supporting structure 21, or the entire structure of the upper portion of the connecting shaft 2221 may be wrapped in the second area 2132 and covered by the outer end surface of the first stopper 214, or the entire structure of the connecting plate 2223 may be wrapped in the third area 2133 and covered by the outer end surface of the second stopper 215, so as to increase the wrapping range and improve the stability of the wrapping fixation.

[0057] like Figure 7As shown, in some specific embodiments, the mounting support 121 is configured as at least one bearing 1211, which is conducive to driving the turntable unit 2 to rotate more smoothly relative to the base unit 1. The diameters of the upper opening 1101 and the lower opening 1102 of the mounting channel 110 are both smaller than the outer diameter of the bearing 1211, so that the bearing 1211 is limited and supported in the mounting channel 110. While supporting the bearing 1211 through the friction between the side wall of the installation channel 110 and the outer side of the bearing 1211, the top wall of the lower opening 1102 can also provide more direct and powerful support to the bottom of the bearing 1211, thereby greatly improving the load-bearing capacity of the base unit, and providing more stable support to the rotating shaft 2222 and the turntable unit 2 as a whole. The bottom of the lower bearing 1211 is limited by the top wall of the lower opening 1102, and the top of the upper bearing 1211 is limited by the bottom wall of the upper opening 1101, so that the installation and positioning structure of the bearing 1211 is more stable, preventing the bearing 1211 from falling off relative to the installation channel 110, thereby avoiding the risk of children tipping over or slipping during rotation, and improving safety during use. The bearing 1211 and the base structure 11 are processed and connected as an integral structure during production, and the bearing 1211 is firmly wrapped and fixed in the installation channel 110 and cannot move relative to the installation channel 110, thereby improving the stability and reliability of the connection between the bearing 1211 and the base structure 11.

[0058] In some specific embodiments, the bearings 1211 are set to three, with strong support and load-bearing capacity, so that the overall load-bearing capacity of the children's sensory integration turntable is better. In other embodiments, the bearings 1211 can also be set to two or other numbers. The bearings 1211 are stacked and placed along the height direction of the installation channel 110. The bearings 1211 include an outer sleeve limited in the installation channel 110 along the height direction of the installation channel 110, and an inner sleeve rotatably connected to the inner side of the outer sleeve. The inner sleeve is coaxially arranged with the outer sleeve, and the center combination of each inner sleeve forms the connection channel 120.

[0059] like Figure 4 , 7-8, in some specific embodiments, the upper portion of the rotating shaft 2222 protrudes outward along its circumferential direction to form a limiting platform 2224, and the lower end of the rotating shaft 2222 is provided with a docking portion 2225 for cooperating with the fastening structure 223. The rotating shaft 2222 can extend into the connecting channel 120 from the upper end of the connecting channel 120, and is clamped between the limiting platform 2224 and the fastening structure 223 by the inner sleeves of each bearing 1211 to limit the height direction of the connecting channel 120. When the turntable unit 2 is driven to rotate, the inner sleeves of each bearing 1211 are driven to rotate. The shaft sleeve rotates relative to the outer shaft sleeve, thereby realizing the rotational connection between the turntable unit 2 and the base unit 1, and can prevent the rotation shaft 2222 from axially moving relative to the connecting channel 120, thereby preventing the turntable unit 2 from axially moving relative to the base unit 1. The rotation shaft 2222 and the connecting channel 120 are mutually abutted or combined to prevent the rotation shaft 2222 from radially moving relative to the connecting channel 120, thereby preventing the turntable unit 2 from radially moving relative to the base unit 1, thereby realizing the installation positioning and rotational connection between the turntable unit 2 and the base unit 1, and the structure is simple and easy to assemble. In this embodiment, the outer wall of the limit platform 2224 has the same radius as the outer wall of the upper part of the connecting shaft 2221, and is smoothly connected as a whole, which simplifies the structure. In other embodiments, the outer wall of the limit platform 2224 can also be arranged at a distance from the outer wall of the upper part of the connecting shaft 2221.

[0060] like Figure 4 , 7 As shown, in some specific embodiments, the fastening structure 223 includes a fastener 2231 and a stopper 2232. The fastener 2231 has a connection end 22311 and an operating end 22312 connected to the connection end 22311. The stopper 2232 is connected to the connection end 22311 and the operating end 22312. The docking portion 2225 is configured as a docking channel formed by a depression on the end surface of the rotating shaft 2222. The connection end 22311 extends into the docking channel and is connected to the rotating shaft 2222. After the connection, the upper side of the stopper 2232 abuts against the lower side of the inner sleeve of the lower end bearing 1211. An internal thread structure is provided in the docking channel, and an external thread structure is provided at the connection end 22311. The fastener 2231 and the rotating shaft 2222 are fastened and connected by the threaded cooperation between the external thread structure and the internal thread structure, which is convenient for installation or disassembly. In this embodiment, the fastener 2231 and the limit block 2232 are integrally formed, and the structure is simple and practical. In other embodiments, the limit block 2232 can also be connected only to any one of the connection end 22311 or the operating end 22312. The fastener 2231 and the limit block 2232 can also be respectively set as independent structures, and the limit block 2232 is mounted on the outside of the connection end 22311 and limited on the operating end 22312 for detachable connection.

[0061] like Figure 7As shown, in some specific embodiments, the limit platform 2224 is arranged in the upper opening 1101 of the installation channel 110 and is spaced apart from the side wall of the upper opening 1101, and the limit block 2232 is arranged in the lower opening 1102 of the installation channel and is spaced apart from the side wall of the lower opening 1102. That is to say, during the rotation of the turntable unit 2 relative to the base unit 1, the limit platform 2224 does not contact the upper opening 1101, and the limit block 2232 does not contact the lower opening 1102, thereby reducing friction and facilitating the smooth rotation of the turntable unit 2.

[0062] like Figure 5-6 As shown in , 8, in some specific embodiments, the base structure 11 includes a base frame 111 at the bottom, a mounting plate 112 at the top, and a base plate 113 arranged along the circumferential direction of the mounting plate 112, the upper end of the base plate 113 is connected to the mounting plate 112 as an integral structure, the lower end of the base plate 113 is connected to the base frame 111 as an integral structure, and the outer surfaces of the mounting plate 112, the base plate 113 and the base frame 111 are smoothly transitioned and connected to form an arc-shaped support structure extending from the top of the mounting plate 112 to the bottom of the base frame 111, the support interface 10 is arranged at the bottom of the base frame 111, and the mounting structure 12 is arranged on the mounting plate 112. The setting of the arc-shaped supporting structure ensures that the forces on various parts of the base unit 1 are relatively uniform during the rotation of the turntable unit 2, so that the structure is stable and strong and not easy to be damaged. The mounting plate 112 is supported at a certain height by the base frame 111 and the base plate 113, and is arranged at intervals from supporting surfaces such as the ground and the floor to form a spherical groove space on the lower side of the base structure 11 for placing objects.

[0063] like Figure 6 As shown, in some specific embodiments, the lower parts of the base frame 111, the mounting plate 112 and the base plate 113 are all provided with a plurality of second support members 114 for providing support force, and the second support members 114 are arranged as block structures protrudingly arranged at intervals and linearly along the lower surface of the base frame 111, the mounting plate 112 or the base plate 113. The base structure 11 is made of plastic material and is processed and formed by production processes such as injection molding and blow molding, which is convenient for mass production. The second support members 114 are used to strengthen the structural strength of the base frame 111, the mounting plate 112 and the base plate 113, and improve the stability and load-bearing capacity of the base structure 11. In other embodiments, the second support members 114 can also be arranged on only one or two structures of the base frame 111, the mounting plate 112 and the base plate 113, which can also strengthen the structural strength of the base structure 11 to a certain extent. The base structure 11 can also be made of other materials such as metal and wood.

[0064] In some specific embodiments, a plurality of second support members 114 are provided, wherein each second support member 114 on the lower surface of the mounting plate 112 includes a second support member 114 with a circular structure and a plurality of second support members 114 with a strip structure and arranged in a clockwise direction with respect to the center of the mounting plate 112. The second support member 114 with a circular structure is coaxially arranged with the connecting shaft 2221, and the radius is set to be larger than the radius of the connecting shaft 2221. A mounting base 1121 arranged corresponding to the mounting channel 110 extends downward from the center of the mounting plate 112 from its lower surface. The mounting structure 12 is provided on the mounting base 1121. The connecting shaft 2221, the mounting channel 110 and the mounting base 1121 are all arranged at an angle with the support interface 10. The angle is set to be greater than 75° and less than 90°, especially greater than 80° and less than 90°, which can ensure the safety of children's sensory integration training. In this case, children can clearly feel the rising and falling sensations during the rotation process. The multiple second support members 114 with strip structures are arranged on the inner side of the second support member 114 with circular structure, and one end is combined with the mounting base 1121, and the other end is combined with the second support member 114 with circular structure, so that the structure of the mounting plate 112 is more stable and strong. The second support members 114 on the lower surface of the base plate 113 are arranged in a strip structure, and one end of a part of the second support members 114 with strip structures is combined with the second support member 114 with circular structure on the lower surface of the mounting structure 12, and the other end is combined with the flange structure on the edge of the base plate 113, so that the structure of the base plate 113 is more stable and strong, which can provide direct and strong support for the pressure at various angles applied to the base structure 11 when the children sit on the load-bearing part 2111, thereby avoiding the mounting plate 112 or the base plate 113 from breaking. The base frame 111 is configured as a double ring structure that is connected to each other at the upper end, and each second support member 114 on the lower surface of the base frame 111 is configured as a strip structure, and the second support members 114 are arranged in a clockwise direction with the center of the base frame 111, and one end of the second support member 114 is connected to the outer ring of the double ring structure, and the other end is connected to the inner ring of the double ring structure, so that the structure of the base frame 111 is more stable and strong, and the support interface 10 is arranged at the bottom of the double ring structure. In this embodiment, an anti-skid pad installed and arranged in the double ring structure is provided, and the bottom of the double ring structure and the bottom surface of the anti-skid pad jointly form the support interface 10. In other embodiments, the anti-skid pad can also be arranged at the bottom of the double ring structure, and the support interface 10 can also be completely formed by the bottom of the double ring structure, or completely formed by the bottom surface of the anti-skid pad. The second support member 114 can also be configured as a curved structure or other shape structures, which can be used to strengthen the structural strength of the mounting plate 112.

On the one hand, it can save materials and production costs. On the other hand, the hollow structure 1130 is connected to the spherical groove space formed on the lower side of the base structure 11, and can be used as a storage channel for the spherical groove space.

[0066] In some specific embodiments, the hollow structure 1130 includes a plurality of first hollow channels 1131 arranged along the circumferential direction of the mounting plate 112, the first hollow channels 1131 extending from the vicinity of the base frame 111 toward the vicinity of the mounting plate 112, the first hollow channels 1131 being evenly spaced, a base member 1133 being formed between two adjacent first hollow channels 1131, the base member 1133 being a plate-like structure, the upper end of the base member 1133 being connected to the mounting plate 112 as an integral structure, and the lower end of the base member 1133 being connected to the base frame 111 as an integral structure. In this embodiment, the first hollow channel 1131 is configured as a fan-shaped structure, the distance between the two sides of the base member 1133 gradually increases from the lower end to the upper end thereof, and the area of ​​the first hollow channel 1131 can be maximized while ensuring stable support for the mounting plate 112, thereby further saving production costs and making it more convenient for children to place or take items into the spherical groove space through the first hollow channel 1131.

[0067] In some specific embodiments, the hollow structure 1130 further includes a plurality of second hollow channels 1132 arranged along the circumferential direction of the mounting plate 112, and the second hollow channels 1132 extend from the vicinity of the mounting plate 112 toward the vicinity of the lower end of the base member 1133, further saving production costs. A base portion 11331 is formed between two adjacent first hollow channels 1131 and second hollow channels 1132, and the upper end of the base portion 11331 is connected to the mounting plate 112 as an integral structure, and the lower end of the base portion 11331 is connected to the base frame 111 as an integral structure.

[0068] In some specific embodiments, the upper ends of the two base portions 11331 arranged on both sides of the first hollow channel 1131 are connected by an arc surface transition, and the lower ends of the two base portions arranged on both sides of the first hollow channel 1131 and the base frame 111 are connected by an arc surface transition. Compared with the transition connection through two intersecting planes, the force on each part of the mounting plate 112, the base plate 113 and the base frame 111 is more uniform and less prone to damage, and the inner wall of the first hollow channel 1131 is smoother and less likely to scratch children.

[0069] like Figure 1-2As shown in Figures 8 and 9, in some specific embodiments, the bearing structure 21 is configured as a disc structure with a simple structure. The opposite sides of the bearing plate 211 are respectively penetrated with gripping channels 2115 for the operator's fingers to insert into, and the gripping member 2112 is arranged on the outside of the gripping channel 2115, so that it is convenient for children to grip the gripping member 2112. The height of the gripping member 2112 is higher than the height of the center point of the bearing portion 2111, and the gripping angle is more in line with the human body structure, and the comfort is better.

[0070] like Figure 9-11 As shown, as the second embodiment of the present invention, a children's sensory integration turntable is also provided. The main difference between the second embodiment and the first embodiment is that a reinforcing column 22231 is further provided on the connecting plate 2223, and the upper end of the reinforcing column 22231 is connected to the lower surface of the supporting member 221, and the reinforcing column 22231 is arranged parallel to the connecting shaft 2221, so as to further enhance the stability and load-bearing capacity of the supporting member 221 structure.

The upper ends of the positioning columns 2114 are combined with the top surface of the first area 2131, and the lower ends of the positioning columns 2114 are combined with the bottom surface of the first area 2131, thereby further firmly wrapping and fixing the support member 221 in the first area 2131, and preventing the support member 221 from circumferentially moving relative to the supporting plate 211.

[0071] like Figure 12-13 As shown, as the third embodiment of the present invention, a children's sensory integration turntable is also provided. The main difference between the third embodiment and the first embodiment is that the bearing structure 21 is set as a fish-shaped structure, which has a richer shape and can better stimulate children's interest in sensory integration training. In other embodiments, the bearing structure 21 can also be set as other animal-shaped structures such as pigs, cows, ducks, or other shaped structures such as triangles, polygons, flowers, etc.
