[0054] The embodiments of the present application will be introduced below with reference to the accompanying drawings of the specification:

[0055] Refer to Figures 1 to 5According to an embodiment of the present application, the dinner plate includes a dinner plate body 100 and a center column 200. The dinner plate body 100 includes a first surface 110 and a second surface 120 opposite to each other along a first direction. The first surface 110 is provided with a snap-fitting protrusion 111. The snap-fitting protrusion 111 is provided with a snap-fitting hole 1111 along the second direction. The first direction is perpendicular to the second direction. The center column 200 is located on the side where the first surface 110 is located. The center column 200 includes a column 210, a fixing portion 220 and a snap-fitting structure 230. Along the second direction, the fixing portion 220 0 is connected to one side of the column 210, the engaging structure 230 is connected to the other side of the column 210, the engaging structure 230 is provided with a limiting protrusion 231, the fixing portion 220 is connected to the first surface 110, the engaging structure 230 penetrates into the engaging hole 1111, the limiting protrusion 231 is located at one end of the engaging structure 230 that penetrates out of the engaging hole 1111, along the first direction, the limiting protrusion 231 extends toward the side away from the second surface 120, and the extension dimension of the limiting protrusion 231 is greater than the extension dimension of the engaging hole 1111 (along the first direction). Thus, the column 210 is connected to the dinner plate body 100 through the fixing portion 220 and the engaging structure 230, and the limiting protrusion 231 can limit the engaging structure 230 from being separated from the engaging hole 1111, which is beneficial to prevent the middle column 200 from being separated from the dinner plate body 100 and improve the safety of the dinner plate.

[0056] Specifically, when the engaging structure 230 is separated from the engaging hole 1111, the limiting protrusion 231 is used to abut against the hole wall of the engaging hole 1111, limiting the engaging structure 230 from being separated from the engaging hole 1111, and ensuring the engagement between the engaging structure 230 and the engaging hole 1111. The fixing portion 220 is connected to the first surface 110, and is used to limit the movement of the column 210 relative to the plate body 100, and prevent the engaging structure 230 from being separated from the engaging hole 1111. Under the joint action of the limiting protrusion 231 and the fixing portion 220, it is helpful to fully ensure the stability of the connection between the center column 200 and the plate body 100, and prevent the center column 200 from being separated from the plate body 100.

[0057] It should be noted that the dining tray is used to connect to the seat 300. The user sits on the seat 300. The center column 200 is located between the user's legs to limit the user's movements. The stable connection between the center column 200 and the dining tray body 100 is beneficial to ensuring the safety of the user.

[0058] refer to Figure 6 and Figure 7 In other embodiments, the center column 200 further includes a cross beam 240. Along the third direction, two cross beams 240 are respectively located on both sides of the column 210. The cross beam 240 is used to support the dining tray body 100 along the first direction to improve the stability of the dining tray body 100. Along the third direction, one end of the cross beam 240 away from the column 210 is provided with a groove 241, and the groove 241 is used to avoid the handle of the seat 300.

[0059] Reference Figure 4 and Figure 5 In some embodiments, along the second direction, on a side of the limiting protrusion 231 close to the engaging hole 1111, there is a first surface 2311, and on a side of the engaging protrusion 111 close to the limiting protrusion 231, there is a second surface 1211. The first surface 2311 and the second surface 1211 are in contact with each other to limit the disengaging of the engaging structure 230 from the engaging hole 1111. Both the first surface 2311 and the second surface 1211 can be perpendicular to the second surface 120. When the engaging structure 230 disengages from the engaging hole 1111, the first surface 2311 abuts against the second surface 1211 to limit the disengaging of the engaging structure 230 from the engaging hole 1111.

[0060] Specifically, along the second direction, the engaging structure 230 can penetrate into or disengage from the engaging hole 1111. Both the first surface 2311 and the second surface 1211 are perpendicular to the second direction. The first surface 2311 is used to abut against the second surface 1211 to limit the disengaging of the engaging structure 230 from the engaging hole 1111, ensuring the clamping connection between the engaging structure 230 and the engaging hole 1111. Compared with the non-planar structure contact between the engaging structure 230 and the inner wall of the engaging hole 1111, it can more effectively limit the disengaging of the engaging structure 230 from the engaging hole 1111.

[0061] Reference Figure 4 and Figure 5 In some embodiments, along the second direction, on a side of the limiting protrusion 231 away from the engaging hole 1111, there is a first guiding inclined surface 2312. Along the direction in which the engaging structure 230 penetrates into the engaging hole 1111, the first guiding inclined surface 2312 gradually inclines towards the second surface 120. The first guiding inclined surface 2312 is configured to abut against the inner wall of the engaging hole 1111 when the engaging structure 230 penetrates into the engaging hole 1111, providing guidance for the clamping connection between the engaging structure 230 and the engaging hole 1111, and facilitating the more labor-saving and smooth penetration of the engaging structure 230 into the engaging hole 1111.

[0062] Reference Figures 4 to 6 In other embodiments, along the second direction, on a side of the limiting protrusion 231 close to the engaging hole 1111, there is a first surface 2311, and on a side of the limiting protrusion 231 away from the engaging hole 1111, there is a first guiding inclined surface 2312. The first guiding inclined surface 2312 is used to abut against the inner wall of the engaging hole 1111 when the engaging structure 230 penetrates into the engaging hole 1111, facilitating the more labor-saving and smooth connection between the middle column 200 and the dinner plate main body 100. The first surface 2311 is used to abut against the inner wall of the engaging hole 1111 when the engaging structure 230 disengages from the engaging hole 1111, for limiting the disengaging of the engaging structure 230 from the engaging hole 1111 and preventing the middle column 200 from disengaging from the connection with the dinner plate main body 100. Thus, the connection between the middle column 200 and the dinner plate main body 100 is more convenient and fast, and can effectively ensure the stability of the connection between the two.

[0063] Reference Figures 4 to 6 In some embodiments, a second guiding inclined surface 1212 is provided on the inner wall of the engaging hole 1111. Along the direction in which the engaging structure 230 penetrates into the engaging hole 1111, the second guiding inclined surface 1212 gradually inclines towards the axis of the engaging hole 1111. That is, the existence of the second guiding inclined surface 1212 causes the aperture of the engaging hole 1111 to gradually decrease. When the engaging structure 230 penetrates into the engaging hole 1111, it abuts against the second guiding inclined surface 1212, facilitating the more smooth penetration of the engaging structure 230 into the engaging hole 1111.

[0064] Reference Figures 4 to 6 In other embodiments, the engaging hole 1111 includes a first hole section and a second hole section. The first hole section is communicated with the second hole section. A second guiding inclined surface 1212 is provided on the hole wall of the second hole section. Along the direction in which the engaging structure 230 penetrates into the engaging hole 1111, the aperture of the second hole section gradually decreases, thereby providing guidance for the penetration of the engaging structure 230. The aperture at any position of the second hole section is smaller than that of the first hole section. The second hole section is beneficial to restricting the engaging structure 230 from disengaging from the engaging hole 1111 and ensuring the clamping connection between the engaging structure 230 and the engaging hole 1111.

[0065] Reference Figures 4 to 6 In other embodiments, when the engaging structure 230 penetrates into the engaging hole 1111, the first guiding inclined surface 2312 abuts against the second guiding inclined surface 1212. As the engaging structure 230 penetrates, the first guiding inclined surface 2312 and the second guiding inclined surface 1212 slide relative to each other. The first guiding inclined surface 2312 and the second guiding inclined surface 1212 are configured to have the same inclination angle relative to the second surface 120, further improving the smoothness of the clamping connection between the engaging structure 230 and the engaging hole 1111.

[0066] It should be noted that after the engaging structure 230 is clamped with the engaging protrusion 111, the limiting protrusion 231 is located outside the engaging hole 1111, that is, the first guiding inclined surface 2312 is located outside the engaging hole 1111, and the first guiding inclined surface 2312 and the second guiding inclined surface 1212 lose contact. When the engaging structure 230 moves along the direction of disengaging from the engaging hole 1111, the first surface 2311 abuts against the second surface 1211, restricting the engaging structure 230 from disengaging from the engaging hole 1111. That is, the first guiding inclined surface 2312 and the second guiding inclined surface 1212 only abut against each other when the engaging structure 230 penetrates into or disengages from the engaging hole 1111, facilitating the penetration or disengagement of the engaging structure 230.

[0067] Reference Figures 5 to 8In some embodiments, the locking structure 230 includes a first locking portion 232 and a second locking portion 233. The first locking portion 232 is connected to the column 210, the second locking portion 233 is connected to the first locking portion 232, and the limiting protrusion 231 is connected to the second locking portion 233. Along the second direction, the second locking portion 233 is located on the side of the first locking portion 232 away from the column 210. Along the third direction, the width of the second locking portion 233 is smaller than the width of the first locking portion 232. The third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction. The setting of the second locking portion 233 facilitates alignment with the locking hole 1111, thereby facilitating the locking connection between the locking structure 230 and the locking protrusion 111.

[0068] Specifically, the locking structure 230 includes a narrower second locking portion 233 and a wider first locking portion 232. When the locking structure 230 penetrates into the locking hole 1111, the second locking portion 233 enters the locking hole 1111 first. The narrower setting of the second locking portion 233 facilitates alignment with the locking hole 1111. The width of the first locking portion 232 is suitable for the size setting of the locking hole 1111, and is used to abut against the inner wall of the locking hole 1111 to prevent the locking structure 230 from shaking relative to the locking hole 1111, thereby improving the stability of the locking between the locking structure 230 and the locking protrusion 111.

[0069] refer to Figures 9 to 13 According to an embodiment of the present application, the high chair includes a seat 300, a first supporting leg 410, a second supporting leg 420 and a dining tray in any of the above embodiments, the dining tray is connected to the seat 300, the first supporting leg 410 includes a first pipe 411 and a second pipe 412, the first pipe 411 and the second pipe 412 are slidably connected, the first pipe 411 is connected to the second supporting leg 420, the second pipe 412 is connected to the seat 300, the first pipe 411 and the second pipe 412 can slide relative to each other to adjust the height of the seat 300, the seat 300 can be used to carry children, and the seat 300 is height-adjustable for feeding children.

[0070] Specifically, the seat 300 is provided with a handle, and the dining tray is detachably connected to the handle. The detachability of the dining tray is more flexible and convenient on the basis of ensuring safety, and is convenient for washing, replacing and carrying the dining tray. The user is placed on the seat 300, and the center column 200 is located between the legs of the user, which restricts the user's activities and effectively prevents the user from falling from the seat 300, thereby providing higher safety. In addition, the first pipe 411 is connected to the second supporting leg 420, and there is an angle between the first pipe 411 and the second supporting leg 420. The two-leg support is beneficial to improving the stability of the high chair, thereby preventing the high chair from tipping over, and further improving the safety of the high chair.

[0071] In some other embodiments, the included angle between the first pipe fitting 411 and the second support leg 420 is adjustable, which helps to better adapt to the ground environment and improve the stability of the support.

[0072] Specifically, connection methods such as rotation and sliding can be adopted between the first pipe fitting 411 and the second support leg 420 to achieve the adjustment of the included angle therebetween.

[0073] Reference Figures 9 to 13 , in some embodiments, the first support leg 410 further includes an operating member 413, a traction member 414, and a locking assembly 415. The operating member 413 is connected to the second pipe fitting 412, and the locking assembly 415 is connected to the second pipe fitting 412. A plurality of locking holes 4111 are provided on the pipe wall of the first pipe fitting 411. The locking assembly 415 is configured to be inserted into any one of the locking holes 4111. When the locking assembly 415 is inserted into the locking hole 4111, it is used to limit the relative sliding between the first pipe fitting 411 and the second pipe fitting 412 and hold the seat 300 at a certain height. The operating member 413 is configured to drive the locking assembly 415 to move through the traction member 414 so that the locking assembly 415 disengages from the locking hole, for unlocking the first pipe fitting 411 and the second pipe fitting 412. After unlocking, the first pipe fitting 411 and the second pipe fitting 412 can slide relative to each other to achieve the height adjustment of the seat 300.

[0074] Specifically, the first pipe fitting 411 is provided with a first lumen, the second pipe fitting 412 is provided with a second lumen, a part of the second pipe fitting 412 penetrates through the first lumen, and the first pipe fitting 411 is slidably connected to the second pipe fitting 412. The operating member 413 is exposed outside the first lumen and the second lumen and is rotatably connected to the second pipe fitting 412. One end of the traction member 414 is connected to the operating member 413, the other end of the traction member 414 is connected to the locking assembly 415, and the locking assembly 415 is connected to the second pipe fitting 412. The locking holes 4111 are spaced along the length extension direction of the first pipe fitting 411. A part of the locking assembly 415 is inserted into the locking hole 4111. The cooperation between the locking assembly 415 and the locking hole 4111 is used to limit the relative sliding between the first pipe fitting 411 and the second pipe fitting 412, that is, to lock the first pipe fitting 411 and the second pipe fitting 412, for stably supporting the seat 300 at a certain height.

[0075] By pressing the operating member 413, the operating member 413 rotates relative to the second pipe fitting 412, the traction member 414 is pulled by the operating member 413, and then the traction member 414 pulls the locking assembly 415 to rotate or move relative to the second pipe fitting 412, so that the locking assembly 415 disengages from the locking hole 4111. When the locking assembly 415 is located outside the locking hole 4111, relative sliding between the first pipe fitting 411 and the second pipe fitting 412 is allowed to adjust the height of the seat 300. After the user releases the operating member 413, along with the relative sliding of the first pipe fitting 411 and the second pipe fitting 412, the locking assembly 415 can re-embed into another locking hole 4111 to achieve locking between the first pipe fitting 411 and the second pipe fitting 412. The locking assembly 415 being located in different locking holes 4111 results in different lengths of the second pipe fitting 412 exposed outside the first lumen, so that the seat 300 has different heights.

[0076] It should be noted that the more the number of locking holes 4111, the greater the height adjustment of the seat. The smaller the interval between the locking holes 4111, the finer the height adjustment of the seat 300. In addition, by arranging the traction member 414 and the locking assembly 415 inside the second lumen, the overall appearance of the high chair is cleaner, which is beneficial to preventing the user from being injured by touching the traction member 414 and the locking assembly 415, thus ensuring the safety of the high chair.

[0077] Reference Figures 9 to 13 , in some embodiments, the locking assembly 415 includes a driving member 4151 and a locking member 4152. The driving member 4151 is movably arranged in the second lumen of the second pipe fitting 412 and is respectively drivingly connected to the traction member 414 and the locking member 4152. The locking member 4152 is rotatably connected to the second pipe fitting 412. The locking member 4152 has a driving portion 4152b and a locking portion 4152a at both ends of the pivot point 4152c. The driving portion 4152b is connected to the driving member 4151, and the locking portion 4152a is used to embed into any locking hole 4111 to restrict the relative sliding between the first pipe fitting 411 and the second pipe fitting 412.

[0078] Specifically, when the user presses the operating member 413, the operating member 413 rotates relative to the second pipe fitting 412. The operating member 413 pulls the driving member 4151 through the traction member 414, so that the driving member 4151 slides relative to the second pipe fitting 412. The driving member 4151 drives the locking member 4152 to rotate relative to the second pipe fitting 412. Further, the locking member 4152 rotates clockwise relative to the second pipe fitting 412 (as Figure 12 shown), so that the locking portion 4152a disengages from the locking hole 4111, and then the relative sliding between the first pipe fitting 411 and the second pipe fitting 412 is achieved.

[0079] It should be noted that when the first pipe fitting 411 slides relative to the second pipe fitting 412, the locking member 4152 moves synchronously with the second pipe fitting 412. As the first pipe fitting 411 slides relative to the second pipe fitting 412, the locking portion 4152a of the locking member 4152 can correspond to the locking holes 4111 at different positions.

[0080] Reference Figure 12 , the locking assembly 415 further includes an elastic member 4153. The two ends of the elastic member 4153 respectively abut against the driving member 4151 and the inner cavity wall of the second pipe fitting 412. The elastic member 4153 is configured to be compressed when the traction member 414 pulls the driving member 4151, and elastically reset when the traction member 414 loses the traction on the driving member 4151. The elastic member 4153 is used to provide the elastic force for the driving member 4151 to reset. When the user releases the operating member 413, when the driving member 4151 resets, it drives the locking member 4152 to rotate counterclockwise (as Figure 12 shown) and re-embed into the locking hole 4111, realizing the locking of the first pipe fitting 411 and the second pipe fitting 412, and ensuring the stability of the high chair support.

[0081] Specifically, the elastic member 4153 can be a spring. When the traction member 414 pulls the driving member 4151 to slide relative to the second pipe fitting 412, the elastic member 4153 is compressed. At this time, the locking portion 4152a of the locking member 4152 is disengaged from the locking hole 4111, allowing the first pipe fitting 411 and the second pipe fitting 412 to slide relative to each other. When the traction member 414 releases the driving member 4151, the elastic member 4153 elastically resets. Under the abutment of the elastic member 4153, the driving member 4151 slides relative to the second pipe fitting 412, and then drives the locking member 4152 to rotate (in the counterclockwise direction as Figure 12 shown), and the locking member 4152 can re-embed into the locking hole 4111 to ensure the locking after the height adjustment of the high chair.

[0082] Reference Figure 12 , in some other embodiments, the driving member 4151 is provided with a guiding groove 4151a. A part of the driving portion 4152b is placed in the guiding groove 4151a. When the driving member 4151 moves, it drives the driving portion 4152b to move along the guiding groove 4151a, so that the locking member 4152 rotates, realizing the locking and unlocking of the first pipe fitting 411 and the second pipe fitting 412.

[0083] Reference Figures 13 to 17, in some embodiments, the first support leg 410 further includes a cover body 416. The cover body 416 is connected to the first pipe fitting 411. The first pipe fitting 411 is provided with a first lumen. The cover body 416 is provided with a through hole 4161. The second pipe fitting 412 passes through the through hole 4161 and extends into the first lumen. A convex portion 4162 is protruded from the inner wall of the cover body 416. The convex portion 4162 abuts against the pipe wall of the second pipe fitting 412, which is beneficial to improving the connection stability between the first pipe fitting 411 and the second pipe fitting 412, preventing the second pipe fitting 412 from shaking in the first lumen, and thus ensuring the stability of the high chair when bearing. The convex portion 4162 can be provided with one, two or more, and there is no specific limitation. The cover body 416 can be located at the upper end of the first pipe fitting 411. The convex portion 4162 can be integrally formed with the cover body 416 or a separate structure provided on the inner wall of the cover body. The convex portion 4162 can be made of plastic, metal or elastic material.

[0084] Reference Figures 13 to 17 , the high chair according to the embodiment of the present application includes a seat 300, a first support leg 410 and a second support leg 420. The first support leg 410 includes a first pipe fitting 411 and a second pipe fitting 412. The first pipe fitting 411 is slidably connected to the second pipe fitting 412 for adjusting the support height of the high chair. The first pipe fitting 411 is connected to the second support leg 420, and the second pipe fitting 412 is connected to the seat. The first support leg 410 further includes a cover body 416. The cover body 416 is connected to the first pipe fitting 411. The first pipe fitting 411 is provided with a first lumen. The cover body 416 is provided with a through hole 4161. The second pipe fitting 412 passes through the through hole 4161 and extends into the first lumen. A convex portion 4162 is protruded from the inner wall of the cover body 416. The convex portion 4162 abuts against the pipe wall of the second pipe fitting 412 to ensure the connection stability between the first pipe fitting 411 and the second pipe fitting 412 and avoid support shaking of the high chair. Specifically, the cover body 416 is located at the end of the connection end of the first pipe fitting 411 and the second pipe fitting 412. It can be understood that in some embodiments not shown, the cover body 416 can also be connected to the second pipe fitting 412. At this time, the first pipe fitting 411 passes through the through hole 4161 and extends into the second lumen of the second pipe fitting 412. The present application is not limited to this.
