DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0038] Please refer to Figures 1-4 As shown, the present application proposes a children's high chair 1 which is highly safe to use.

[0039] The children's high chair 1 includes a fixed base 10, a seat 20, and a limiting member 30. The fixed base 10 has an assembly position 11 and a locking portion 12. The locking portion 12 is provided on both sides of the assembly position 11 along the left-right direction YY' of the children's high chair 1. The seat 20 includes a base 21 and a locking assembly 22. The base 21 is provided on the fixed base 10 corresponding to the assembly position 11. The locking assembly 22 is installed on both sides of the base 21 along the left-right direction YY' of the children's high chair 1. The locking assembly 22 has a locked state and an unlocked state. In the locked state, the locking assembly 22 is configured to lock with the locking portion 12 to lock the base 21 to the fixed base 10. In the unlocked state, the locking assembly 22 is configured to disengage from the locking portion 12 to release the base 21 from the fixed base 10. The locking assembly 22 can switch between the locked state and the unlocked state. The limiting member 30 is provided on at least one of the rear side wall of the fixing seat 10 and the rear side wall of the base 21; when the lock / release assembly 22 is in the locked state, the limiting member 30 is clamped between the rear side wall of the fixing seat 10 and the rear side wall of the base 21 to limit the relative movement of the fixing seat 10 and the base 21 in the front-to-back direction XX' of the children's high chair 1.

[0040] The following combination Figures 1-11 The specific structure of the children's high chair 1 is introduced in detail.

[0041] like Figures 1-4 As shown, the children's high chair 1 includes a fixing base 10 , a seat 20 and a limiting member 30 .

[0042] The fixed seat 10 serves as a support for the children's high chair 1; the specific structure of the fixed seat 10 is not limited here, and designers can make reasonable designs according to actual needs; for example, the fixed seat 10 includes a bottom wall, a rear side wall, and left and right side walls, and the bottom wall, rear side wall, and left and right side walls are connected to enclose a support structure with openings on both sides.

[0043] The fixing base 10 has an assembly position 11; the assembly position 11 is the position on the fixing base 10 for installing the base 21 (a subcomponent of the seat 20, which will be introduced below); for example, when the fixing base 10 includes a bottom wall 11a, a rear side wall 11b and left and right side walls 11c, the area enclosed by the bottom wall 11a, the rear side wall 11b and the left and right side walls 11c serves as the assembly position 11.

[0044] The fixed seat 10 has a locking portion 12; this is the structure on the fixed seat 10 that cooperates with the lock / release assembly 22 (a subcomponent of the seat 20, described below) to achieve relative fixation or change of position between the base 21 and the fixed seat 10. The specific form of the locking portion 12 is not limited here; designers can reasonably design it based on actual needs. For example, the locking portion 12 can be, but is not limited to, a physical structure provided on the fixed seat 10, such as a lock buckle 12a. In another example, the locking portion 12 can also be, but is not limited to, a virtual structure formed on the fixed seat 10, such as a keyhole.

[0045] The locking portions 12 are disposed on either side of the assembly position 11 along the left-right direction YY' of the children's high chair 1. For example, when the fixing base 10 includes a bottom wall 11a, a rear side wall 11b, and left and right side walls 11c, the area enclosed by the bottom wall 11a, the rear side wall 11b, and the left and right side walls 11c serves as the assembly position 11, and the locking portions 12 are disposed on the left and right side walls 11c.

[0046] like Figures 1-4 As shown, the seat 20 is used as the seat of the children's high chair 1 for children to sit on. The seat 20 includes a base 21 and a lock and release assembly 22.

[0047] The base 21 serves as the seat body of the chair 20; the specific structure of the base 21 is not limited here, and designers can make reasonable designs according to actual needs; for example, the base 21 includes a bottom wall 21a, a rear side wall 21b and left and right side walls 21c, and the bottom wall 21a, the rear side wall 21b and the left and right side walls 21c are connected to enclose a seat body structure with openings on both sides.

[0048] The base 21 is disposed on the fixing base 10 in correspondence with the assembly position 11. For example, when the fixing base 10 includes a bottom wall 11a, a rear side wall 11b, and left and right side walls 11c, the area enclosed by the bottom wall 11a, the rear side wall 11b, and the left and right side walls 11c serves as the assembly position 11. In this case, the base 21 corresponds to the assembly position 11, and a portion of the base 21 is embedded in the assembly position 11, thereby forming a partially nested structure between the base 21 and the fixing base 10. This effectively enhances the overall structural strength of the children's high chair 1, thereby improving the safety of the children's high chair 1.

[0049] The lock / release assembly 22 serves as the locking mechanism for the seat 20. When a caregiver needs to assemble the seat 20 onto the fixed seat 10 for a child to ride on, the lock / release assembly 22 can be used to relatively secure the base 21 and the fixed seat 10. Furthermore, the lock / release assembly 22 serves as the unlocking mechanism for the seat 20. When a caregiver needs to remove the seat 20 from the fixed seat 10 for a child to ride on their own, the lock / release assembly 22 can be used to release the lock / release mechanism from the fixed seat 10. The specific structure of the lock / release assembly 22 will be described in detail below.

[0050] The locking and releasing components 22 are installed on both sides of the base 21 along the left-right direction YY' of the children's high chair 1. For example, when the base 21 includes a bottom wall 21a, a rear side wall 21b and left and right side walls 21c, the locking and releasing components 22 are installed on the left and right side walls 21c.

[0051] The unlocking assembly 22 has a locked state, and when the unlocking assembly 22 is in the locked state, the unlocking assembly 22 is configured to lock with the matching locking portion 12 to lock the base 21 to the fixed seat 10. At this time, the base 21 is positioned on the fixed seat 10 via the unlocking assembly 22, and the position between the base 21 and the fixed seat 10 is relatively fixed, and the caregiver can allow the child to sit on the combination formed by the seat 20 and the fixed seat 10.

[0052] The lock release assembly 22 also has a released state, and when the lock release assembly 22 is in the released state, the lock release assembly 22 is configured to disengage from the matching lock portion 12 to unlock the base 21 from the fixed seat 10. At this time, the base 21 is released from the fixed seat 10 via the lock release assembly 22, and the position between the base 21 and the fixed seat 10 is relatively changed, so that the caregiver can let the child sit on the seat 20 alone.

[0053] The lock / release assembly 22 can switch between the aforementioned locked and unlocked states. It should be noted that the lock / release assembly 22 can be switched between the locked and unlocked states manually, such as by applying a pressing force, or automatically, such as by providing a transmission force to the lock / release assembly 22. It should be understood that the specific structure of the lock / release assembly 22 will vary depending on the different modes, and the specific form of the locking portion 12 that cooperates with the lock / release assembly 22 will also vary.

[0054] like Figures 1-4 As shown, the limiting member 30 serves as a limiting structure of the children's high chair 1 and can be used to limit the relative movement between the fixing seat 10 and the base 21 in the front-to-back direction XX' of the children's high chair 1. The specific form of the limiting member 30 will be described in detail below.

[0055] The limiting member 30 is provided on at least one of the rear side wall 11b of the fixing seat 10 and the rear side wall 21b of the base 21. For example, the limiting member 30 can be provided solely on the rear side wall 11b of the fixing seat 10; for another example, the limiting member 30 can also be provided solely on the rear side wall 21b of the base 21; for another example, the limiting member 30 includes two parts, one part can be provided on the rear side wall 11b of the fixing seat 10, and the other part can be provided on the rear side wall 21b of the base 21. In this embodiment, as Figure 4 As shown, the limiting member 30 is arranged on the rear side wall 21b of the base 21, specifically, it is arranged on the side of the rear side wall 21b of the base 21 facing the fixed base 10, extends toward the rear side wall 11b of the fixed base 10, and abuts against the rear side wall 11b of the fixed base 10. When the base 21 is locked to the fixed base 10, the base 21 and the fixed base 10 are tightly matched, which can prevent the base 21 from moving relative to the fixed base 10 in the front-to-back direction XX'. There is no limitation on the specific connection method between the limiting member 30 and the rear side wall 11b of the fixing seat 10 and / or the rear side wall 21b of the base 21, and designers can make reasonable designs according to actual needs; for example, the limiting member 30 can be, but is not limited to, a detachable connection with the rear side wall 11b of the fixing seat 10 and / or the rear side wall 21b of the base 21 by at least one of screw connection, snap connection or plug-in connection; for another example, the limiting member 30 can also be, but is not limited to, a non-detachable connection with the rear side wall 11b of the fixing seat 10 and / or the rear side wall 21b of the base 21 by gluing, riveting or integral molding.

[0056] When the lock / release assembly 22 is in the locked state, the limiting member 30 is clamped between the rear side wall 11b of the fixing seat 10 and the rear side wall 21b of the base 21 to limit the relative movement of the fixing seat 10 and the base 21 in the front-to-back direction XX' of the children's high chair 1.

[0057] Based on the children's high chair 1 in the embodiment of the present application, by designing a limit member 30, in the above-mentioned locked state of the lock and release assembly 22, the limit member 30 is clamped between the rear side wall 11b of the fixed seat 10 and the rear side wall 21b of the base 21. The limit member 30 abuts against the rear side wall 11b of the fixed seat 10 and the rear side wall 21b of the base 21 to limit the relative movement of the fixed seat 10 and the base 21 in the front-to-back direction XX' of the children's high chair 1. This can effectively reduce the possibility of the seat 20 shaking relative to the fixed seat 10 when assembled on the fixed seat 10, thereby effectively improving the safety of the children's high chair 1.

[0058] It is worth mentioning that when the unlocking assembly 22 is in the above-mentioned locked state, the base 21 corresponds to the assembly position 11 and the fixed seat 10 to form an inner and outer nested structure, which can limit the relative movement of the fixed seat 10 and the base 21 in the left and right direction YY' of the children's high chair 1; the unlocking assembly 22 is locked with the matching lock portion 12, which can limit the relative movement of the fixed seat 10 and the base 21 in the up and down direction ZZ' of the children's high chair 1; and the limiting member 30 is clamped on the rear side wall 11b of the fixed seat 10 and the base. The rear side wall 21b of 21 can limit the relative movement of the fixing seat 10 and the base 21 in the front-to-back direction XX' of the children's high chair 1; in this way, the fixing seat 10 and the base 21 can be positioned and matched in multiple directions in the left-right direction YY', the up-down direction ZZ' and the front-to-back direction XX' of the children's high chair 1, so as to further effectively reduce or even avoid the possibility of the seat 20 shaking relative to the fixing seat 10 when assembled on the fixing seat 10, thereby effectively improving the safety of the children's high chair 1.

[0059] like Figure 3-Figure 4 As shown, the limiting member 30 includes a limiting rib 31; the limiting rib 31 is disposed on the rear sidewall 21b of the base 21. Specifically, the limiting rib 31 is disposed on the side of the rear sidewall 21b of the base 21 facing the fixing base 10, extends toward the rear sidewall 11b of the fixing base 10, and abuts against the rear sidewall 11b of the fixing base 10. When the lock / release assembly 22 is in the locked state, the side of the limiting rib 31 facing away from the rear sidewall 21b of the base 21 abuts against the rear sidewall 11b of the fixing base 10.

[0060] The limiting rib 31 may be, but is not limited to, detachably connected to the rear side wall 21b of the base 21 by at least one of screwing, snapping, or plugging. The limiting rib 31 may also be, but is not limited to, non-detachably connected to the rear side wall 21b of the base 21 by gluing, riveting, or integral molding. The number of limiting ribs 31 may be one or more (two or more). For example, when there is one limiting rib 31, the limiting rib 31 may be, but is not limited to, located in the middle of the rear side wall 21b of the base 21. For another example, when there are multiple limiting ribs 31, the multiple limiting ribs 31 may be, but are not limited to, arranged at intervals on the rear side wall 21b of the base 21 along the left-right direction YY' of the children's high chair 1.

[0061] By designing the limiting rib 31, when the lock / release assembly 22 is in the locked state, the limiting rib 31 is clamped between the rear side wall 11b of the fixing seat 10 and the rear side wall 21b of the base 21. The side of the limiting rib 31 facing away from the rear side wall 21b of the base 21 abuts against the rear side wall 11b of the fixing seat 10, thereby limiting relative movement between the fixing seat 10 and the base 21 in the front-to-back direction XX' of the children's high chair 1. This effectively reduces the possibility of the seat 20 rocking relative to the fixing seat 10 when assembled on the fixing seat 10, thereby effectively improving the safety of the children's high chair 1. It is worth noting that the limiting rib 31 designed on the rear side wall 21b of the base 21 also acts as a reinforcing rib, which can enhance the structural strength of the rear side wall 21b of the base 21, effectively reducing the possibility of deformation or breakage of the base 21 when a child is seated on the seat 20, thereby improving the safety of the children's high chair 1.

[0062] Specifically, the limiting rib 31 extends along the vertical direction ZZ' of the children's high chair 1 and is in the form of an elongated strip. This increases the contact area between the elongated strip and the rear sidewall 11b of the mounting base 10 when the lock / release assembly 22 is in the locked state. This improves the stability of the base 21 mounted on the mounting base 10, further reducing the possibility of the seat 20 shaking relative to the mounting base 10 when assembled, thereby further enhancing the safety of the children's high chair 1. The limiting rib 31 has a thickness D in the front-to-back direction XX' of the children's high chair 1, and the thickness D of the limiting rib 31 gradually increases from top to bottom along the up-down direction ZZ' of the children's high chair 1 to match the fitting curvature of the rear side wall 11b of the fixing seat 10 and the rear side wall 21b of the base 21; thus, based on the inclination of the rear side wall 21b of the base 21, the limiting rib 31 with varying thickness D can provide better support stability for the base 21 and improve the structural strength of the rear side wall 21b of the base 21.

[0063] The limiting rib 31 is integrally formed with the rear side wall of the base 21 by injection molding or 3D printing, which can effectively reduce the difficulty of processing between the limiting rib 31 and the rear side wall 21b of the base 21.

[0064] Of course, in other embodiments, the limiting member 30 may also include a bayonet (not shown in the figure), which extends along the front-to-back direction XX' of the children's high chair 1, and is arranged on at least one of the rear side wall 11b of the fixing seat 10 and the rear side wall 21b of the base 21. At least the other of the rear side wall 11b of the fixing seat 10 and the rear side wall 21b of the base 21 is provided with a locking hole (not shown in the figure), and the bayonet is engaged with the locking hole to limit the relative movement of the fixing seat 10 and the base 21 in the front-to-back direction XX' of the children's high chair 1.

[0065] like Figure 5-Figure 6 As shown, the lock / release assembly 22 includes an operating member 221 and a locking member 222. The operating member 221 is disposed on the left and right side walls 21c of the base 21 and is movably connected to the left and right side walls 21c of the base 21. The locking member 222 is connected to the operating member 221. The operating member 221 is configured to move relative to the base 21 under the action of an external force, thereby driving the locking member 222 to disengage from the locking portion 12, thereby unlocking the base 21 from the fixed base 10. By designing the operating member 221 and the locking member 222, an external force is applied to the operating member 221, causing the operating member 221 to move relative to the base 21 under the action of the external force. The movement of the operating member 221 drives the connected locking member 222 to disengage from the locking portion 12, at which point the base 21 is released from the fixed base 10, and the seat 20 can be removed from the fixed base 10.

[0066] Specifically, the specific forms of the operating member 221 and the locking member 222, as well as the specific forms of the corresponding locking portion 12, may include but are not limited to the following embodiments.

[0067] In one embodiment, if Figure 5-Figure 6 As shown, the locking portion 12 includes locks 12a disposed on the left and right side walls 21c of the base 21; the operating member 221 includes a handle 221a, which is rotatably connected to the left and right side walls 21c of the base 21 (the rotation axis of the handle 221a extends along the front-to-back direction XX' of the children's high chair 1); and the locking member 222 includes a hook 222a, which is cantilevered. The fixed end of the hook 222a is fixedly connected to the handle 221a, and the hook end of the hook 222a is engaged with the lock 12a. When the handle 221a rotates relative to the base 21 under the action of an external force, the rotation of the handle 221a drives the connected hook 222a to rotate relative to the base 21 until the hook end of the hook 222a disengages the lock 12a. At this time, the base 21 and the fixed base 10 are released, and the seat 20 can be removed from the fixed base 10.

[0068] Of course, based on the above embodiment, the lock releasing assembly 22 further comprises a first elastic member 223, two ends of the first elastic member 223 respectively abut against the left and right side walls of the base 21 and the handle 221a; when the handle 221a rotates relative to the base 21, the first elastic member 223 elastically deforms. The first elastic member 223 can be but is not limited to a spring; when the handle 221a rotates relative to the base 21, the first elastic member 223 is stretched by the handle 221a to elastically deform. By designing the first elastic member 223, when the handle 221a is not subjected to an external force, the two ends of the first elastic member 223 respectively abut against the left and right side walls 21c of the base 21 and the handle 221a, so that the first elastic member 223 has an initial elastic deformation, and the handle 221a can drive the clasp hook 222a connected thereto and make the hooking end of the clasp hook 222a abut against the lock catch 12a under the elastic force generated by the initial elastic deformation, so as to enhance the connection stability between the clasp hook 222a and the lock catch 12a, thereby enhancing the connection stability when the base 21 is positioned on the fixing base 10. By designing the first elastic member 223, the first elastic member 223 is suitable for further elastically deforming (greater than the initial elastic deformation) under the action of the external force, and the elastic force generated by the elastic deformation is suitable for acting on the external force on the handle 221a after the external force is removed to realize the automatic reset of the clasp hook 222a.

[0069] In another embodiment not shown, the lock portion 12 comprises a lock hole (not shown in the figure) formed on the left and right side walls 21c of the base 21; the operating member 221 comprises a button (not shown in the figure), which is in sliding connection with the left and right side walls 21c of the base 21 (the button can slide relative to the base 21 along the up-down direction ZZ' of the high chair 1); the locking member 222 comprises a locking pin (not shown in the figure), which is in sliding connection with the left and right side walls 21c of the base 21 (the locking pin can slide relative to the base 21 along the left-right direction YY' of the high chair 1), and the locking pin has a driving slope; the button abuts against the driving slope of the locking pin. Under the action of an external force, the button slides relative to the base 21, and the button slides to push the driving slope to make the locking pin slide relative to the base 21 to disengage the locking pin from the lock hole, at which time the base 21 is released from the fixing base 10, and the seat 20 can be detached from the fixing base 10.

[0070] Of course, based on the above embodiment, the lock release assembly 22 also includes a second elastic member (not shown in the figure), the two ends of which respectively abut the left and right side walls 21c of the base 21 and the locking pin; when the button slides relative to the base 21, the button pushes the driving inclined surface so that the locking pin squeezes the second elastic member and moves to disengage from the lock hole. The second elastic member can be, but is not limited to, a spring or a spring sheet, and the second elastic member is suitable for generating elastic deformation under the squeezing action of the locking pin. By designing the second elastic member, when the button is not subjected to external force, the two ends of the second elastic member respectively push against the left and right side walls 21c of the base 21 and the locking pin, so that the second elastic member has an initial elastic deformation. Under the action of the elastic force generated by the initial elastic deformation, the locking pin can be pressed against the lock hole to enhance the connection stability between the locking pin and the lock hole, thereby enhancing the connection stability when the base 21 is positioned on the fixing seat 10. By designing a second elastic member, the second elastic member is suitable for further generating elastic deformation (greater than the above initial elastic deformation) under the action of the above external force. The elastic force generated by the elastic deformation is suitable for realizing automatic resetting of the locking pin after the external force acting on the button is removed.

[0071] like Figure 7 As shown, the seat 20 also includes a backrest 23 and a shielding member 24; the backrest 23 is connected to the base 21; the shielding member 24 is arranged on at least one of the backrest 23 and the base 21, and the shielding member 24 is used to cover the assembly gap formed between the backrest 23 and the base 21.

[0072] The backrest 23 serves as the backrest of the seat 20. The specific structure of the backrest 23 is not limited here, and designers can reasonably design it according to actual needs. The backrest 23 can be rotatably connected to the base 21. In this case, the backrest 23 can be rotatably connected to the base 21 via a rotating shaft to allow the angle of the backrest 23 to be adjusted. Of course, the backrest 23 can also be fixedly connected to the base 21.

[0073] The shielding member 24 serves as a shielding structure for the seat 20, and is used to shield the assembly gap formed between the backrest 23 and the base 21, thereby reducing or even preventing the possibility of pinching a child's fingers. The specific form of the shielding member 24 will be described in detail below. The specific connection method between the shielding member 24 and the backrest 23 and / or the base 21 is not limited here, and designers can make reasonable designs based on actual needs. For example, the shielding member 24 can be, but is not limited to, detachably connected to the backrest 23 and / or the base 21 by at least one of screwing, snapping, or plugging. For another example, the shielding member 24 can be, but is not limited to, non-detachably connected to the backrest 23 and / or the base 21 by gluing, riveting, or integral molding.

[0074] The backrest 23 is designed to be connected to the base 21 to provide support for the child's back and / or head, thereby improving the comfort of the children's high chair 1. The shielding member 24 is designed to cover the assembly gap between the backrest 23 and the base 21, thereby effectively reducing or even preventing the possibility of pinching a child's fingers.

[0075] Specifically, the specific forms of the shielding member 24 may include, but are not limited to, the following embodiments.

[0076] In the first embodiment, the shielding member 24 includes a first shielding rib 241, which is provided on the left and right side walls of the backrest 23 and blocks the upper side of the assembly gap formed between the backrest 23 and the base 21. The first shielding rib 241 is arc-shaped, and the arc-shaped first shielding rib 241 extends generally along the front-to-back direction XX' of the children's high chair 1. The first shielding rib 241 is integrally formed with the left and right side walls of the backrest 23 by injection molding or 3D printing, which effectively reduces the processing difficulty between the first shielding rib 241 and the left and right side walls of the backrest 23. By designing the first shielding rib 241, the first shielding rib 241 is used to effectively block the upper side of the assembly gap formed between the backrest 23 and the base 21, which effectively reduces or even avoids the possibility of pinching a child's fingers.

[0077] In the second embodiment, the shielding member 24 includes a second shielding rib 242, which is provided on the left and right side walls of the backrest 23, and the second shielding rib 242 shields the rear side of the assembly gap formed between the backrest 23 and the base 21. The second shielding rib 242 is linear, and the linear second shielding rib 242 extends approximately along the up-down direction ZZ' of the children's high chair 1. The second shielding rib 242 is integrally formed with the left and right side walls of the backrest 23 by injection molding or 3D printing, which effectively reduces the processing difficulty between the second shielding rib 242 and the left and right side walls of the backrest 23. By designing the second shielding rib 242, the second shielding rib 242 is used to effectively shield the rear side of the assembly gap formed between the backrest 23 and the base 21, which effectively reduces or even avoids the possibility of pinching children's fingers.

[0078] In the third embodiment, the shielding member 24 includes a first shielding rib 241 and a second shielding rib 242. The first shielding rib 241 and the second shielding rib 242 are disposed on the left and right side walls of the backrest 23, and are disposed at an angle thereto. Specifically, the first shielding rib 241 extends generally along the front-to-back direction XX' of the children's high chair 1 and shields the upper side of the assembly gap formed between the backrest 23 and the base 21. The second shielding rib 242 extends generally along the vertical direction ZZ' of the children's high chair 1 and shields the rear side of the assembly gap formed between the backrest 23 and the base 21.

[0079] Of course, in other embodiments not shown, the shielding member 24 may also include multiple shielding columns (not shown in the figure), and the multiple shielding columns are arranged on at least one of the backrest 23 and the base 21, and the interval between two adjacent shielding columns is small, so as to effectively shield the assembly gap formed between the backrest 23 and the base 21.

[0080] like Figure 8-Figure 9 As shown, the rear sidewall 21b of the base 21 is provided with a through-hole 21d. The children's high chair 1 also includes a fixing member 40 disposed on the rear sidewall 21b of the base 21 and adjacent to the through-hole 21d. The children's high chair 1 also includes a strap (not shown) passing through the through-hole 21d and connected to the fixing member 40.

[0081] The through hole 21d is an opening formed on the rear side wall 21b of the base 21 for the strap to pass through. The number of the through holes 21d can be one, two, or more (more than two).

[0082] The fixing member 40 serves as a fixing structure for the children's high chair 1, and is used to secure the strap to prevent the end of the strap from falling off. The specific form of the fixing member 40 will be described in detail below. The specific connection method between the fixing member 40 and the rear side wall 21b of the base 21 is not limited here, and designers can reasonably design it according to actual needs. For example, the fixing member 40 can be, but is not limited to, a detachable connection to the rear side wall 21b of the base 21 through at least one of screwing, snapping, or plugging. For another example, the fixing member 40 can also be, but is not limited to, a non-detachable connection to the rear side wall 21b of the base 21 through gluing, riveting, or integral molding.

[0083] The straps serve as the binding structure of the children's high chair 1 and are used to bind and position a child carried on the seat 20 to improve the child's safety. The number of straps can be one, two, or more (more than two); for example, when there is one strap, both the head and tail ends of the strap are provided with through holes 21d and connected to the fixing member 40. In this case, the strap is elastic and the child can be bound within the circle formed by the strap; for another example, when there are two straps, both tail ends of the straps are provided with through holes 21d and connected to the fixing member 40. In this case, the head ends of the two straps are connected by a buckle, and the child can be bound within the circle formed by the two straps connected by the buckle.

[0084] By designing a through hole 21d on the rear side wall 21b of the base 21, the strap passes through the through hole 21d and is connected to the fixing member 40 so that the strap is fixed on the fixing member 40. This can effectively prevent the end of the strap from falling off, thereby ensuring the safety of the child being tied with the strap, and preventing the end of the strap from falling off and interfering with the installation and use of other components.

[0085] Specifically, the fixing member 40 includes a fixing plate 41; one end of the fixing plate 41 is connected to the rear side wall 21b of the base 21; and the end of the strap is looped and fits over the fixing plate 41. The fixing plate 41 is L-shaped, with a portion of the L-shaped fixing plate 41 connected to the rear side wall 21b of the base 21 and extending along the front-to-back direction XX' of the children's high chair 1; another portion of the L-shaped fixing plate 41 extends along the up-down direction ZZ' of the children's high chair 1 and is parallel to and spaced apart from the rear side wall 21b of the base 21 (i.e., the fixing plate 41 is cantilevered). It is understood that the fixing plate 41 is disposed on the side of the rear side wall 21b of the base 21 that faces away from the rear side wall 11b of the fixing base 10, and a gap is formed between the fixing plate 41 and the rear side wall 21b of the base 21 to secure and accommodate the end of the strap. The fixing plate 41 is integrally formed with the rear sidewall 21b of the base 21 through injection molding or 3D printing, effectively simplifying the processing between the fixing plate 41 and the rear sidewall 21b of the base 21. The design of the fixing plate 41 allows the ends of the strap to form a loop and fit over the fixing plate 41, confining the strap to the fixing plate 41. This effectively prevents the strap from falling off, ensuring the safety of the child being restrained by the strap.

[0086] Of course, in other embodiments not shown, the fixing member 40 may also include a fixing pin (not shown in the figure), which passes through the strap and is plugged into the socket on the rear side wall 21b of the base 21 to fix the strap.

[0087] like Figure 10-11 As shown, the children's high chair 1 further includes a support leg 50 , which includes an upper rod 51 and a lower rod 52 . The upper rod 51 and the lower rod 52 are detachably connected, and the fixing seat 10 is connected to the upper rod 51 .

[0088] The upper rod 51 and the lower rod 52 are detachably connected. The position of the fixing base 10 relative to the upper rod 51 is adjustable, and the fixing base 10 can be fixedly connected to the upper rod 51 by at least one of screw connection, clamping connection or plug connection, but is not limited to the above.

[0089] By designing the support legs 50 as detachable upper rods 51 and lower rods 52 , a caregiver can change the height of the children's high chair 1 by removing the lower rod 52 to adapt to the children's riding needs in different scenarios.

[0090] Specifically, a snap-fitting arm 53 is provided on one of the bottom end of the upper rod 51 and the top end of the lower rod 52, and a snap-fitting hole 54 is provided on the other of the bottom end of the upper rod 51 and the top end of the lower rod 52. The free end of the snap-fitting arm 53 snaps into the snap-fitting hole 54 to achieve relative fixation between the upper rod 51 and the lower rod 52. This facilitates the installation of the upper rod 51 and the lower rod 52. Conversely, the upper rod 51 and the lower rod 52 can be removed by applying a force to the snap-fitting arm 53 to disengage the free end of the snap-fitting arm 53 from the snap-fitting hole 54.

[0091] More specifically, the support leg 50 further includes a connecting base 55, the upper rod 51 includes a front upper support rod 511 and a rear upper support rod 512, and the lower rod 52 includes a front lower support rod 521 and a rear lower support rod 522. The top ends of the front upper support rod 511 and the rear upper support rod 512 are both rotatably connected to the connecting base 55, and the bottom ends of the front upper support rod 511 and the rear upper support rod 512 are both provided with a snap-fitting elastic arm 53; the top ends of the front lower support rod 521 and the rear lower support rod 522 are both provided with a snap-fitting hole 54. The top end of the front lower support rod 521 is sleeved over the bottom end of the front upper support rod 511 and engages with the free end of the engaging arm 53 through the engaging hole 54 to achieve relative fixation between the front lower support rod 521 and the front upper support rod 511. The top end of the rear lower support rod 522 is sleeved over the bottom end of the rear upper support rod 512 and engages with the free end of the engaging arm 53 through the engaging hole 54 to achieve relative fixation between the rear lower support rod 522 and the rear upper support rod 512. The fixing base 10 is connected to the front upper support rod 511. The free end of the engaging arm 53 is provided with an engaging protrusion 531. When engaged, the engaging protrusion 531 of the free end of the engaging arm 53 engages with the engaging hole 54. When disassembled, the engaging protrusion 531 is pressed to compress the engaging arm 53, thereby causing the engaging protrusion 531 to retreat from the engaging hole 54.
