[0013] Furthermore, the protrusion is provided with a first inclined wall, and the slot is provided with a second inclined wall, with the first inclined wall movably abutting against the second inclined wall;
[0014] The protrusion can press against the second inclined wall through the first inclined wall, causing the second locking member to move away from the protrusion.
[0015] Furthermore, a first tension spring is provided between the backrest and the second locking member, with one end of the first tension spring abutting against the backrest and the other end abutting against the second locking member;
[0016] When the protrusion pushes against the second locking member, unlocking the dinner plate and the backrest: the first tension spring is compressed.
[0017] Furthermore, the second locking member is configured as a locking gear, and the locking gear has a plurality of slots along its circumference, and the rear foot has a plurality of protrusions, with the plurality of protrusions corresponding one-to-one with the plurality of slots.
[0018] Furthermore, the seat plate is rotatably connected to the front foot, and a seat plate bracket is provided on the rear foot, with a locking groove on the seat plate bracket;
[0019] When the child high chair is in the unfolded state: the seat support bracket supports the seat, and the first locking member locks into the locking groove, locking the seat between the front leg and the rear leg.
[0020] Furthermore, a second tension spring is provided between the seat plate and the first locking member, with one end of the second tension spring abutting against the first locking member and the other end abutting against the seat plate;
[0021] When the first locking member is pulled to disengage from the locking groove, the second tension spring is compressed.
[0022] Furthermore, the seat plate bracket is rotatably mounted on the rear foot, and the seat plate is rotatably connected to the seat plate bracket;
[0023] When the first locking member releases its lock on the seat plate, the front foot and the rear foot rotate and fold together, and the seat plate and the seat plate bracket fold onto the front foot and the rear foot.
[0024] Furthermore, the first locking member is slidably disposed at the bottom of the seat plate;
[0025] The base plate is provided with a through groove running from top to bottom, and a pull rope is connected to the first locking member, which passes through the through groove from bottom to top.
[0026] Furthermore, both the front foot and the rear foot are provided with multiple limiting protrusions for the strap to be wound around;
[0027] Both the front and rear legs can be supported on the seat, and the straps can be wrapped around the limiting protrusion to fix the child dining chair to the seat.

[0051] like Figures 1-4 As shown, a foldable children's high chair has an unfolded state and a folded state. When the children's high chair is in the unfolded state (e.g., Figures 1-3 When the child is seated in the high chair (as shown), they can eat. When the high chair is folded down (as shown), the child can eat while seated in the high chair. Figure 9 As shown in the last picture, the folded children's high chair is compact in size, occupies little space, and is easy to store and carry. The foldable children's high chair in this embodiment mainly includes: support legs 1, seat 2, tray 3, and backrest 4. Among them, the support legs 1 mainly include front legs 11 and rear legs 12.
[0052] The support leg 1 includes a rotatably connected front leg 11 and rear leg 12. Specifically, both the front leg 11 and rear leg 12 are approximately U-shaped, and each end of the front leg 11 and rear leg 12 has a joint. The two joints of the front leg 11 and the two joints of the rear leg 12 are rotatably connected, realizing the rotatable connection between the front leg 11 and the rear leg 12. In this embodiment of the child high chair, both the front leg 11 and the rear leg 12 are provided with multiple limiting protrusions 110 for the strap to be wound around. Each limiting protrusion 110 includes a small-diameter protrusion and a large-diameter protrusion. The large-diameter protrusion is located at the end of the small-diameter protrusion. When the strap is wound around the limiting protrusion 110, the strap can be wound around the small-diameter protrusion, while the large-diameter protrusion can prevent the strap from slipping off the small-diameter protrusion, ensuring reliable winding of the strap, that is, ensuring that the strap can reliably fix the child seat.
[0053] In actual use, both the front legs 11 and the rear legs 12 of the children's high chair can be supported on the seat, and the straps can be wrapped around the limiting protrusions 110 to fix the children's high chair to the seat. When the children's high chair is placed on the ground, it can be used as a regular dining chair. When both the front legs 11 and the rear legs 12 are supported on the seat, and the straps are wrapped around the limiting protrusions 110 to fix the children's high chair to the seat, it can be used as a high chair, thus realizing the function of a chair-on-chair for children.
[0054] like Figures 7-8 and combined Figure 4 As shown, the seat 2 is movably mounted on the support leg 1, specifically, the seat 2 is movably mounted between the front leg 11 and the rear leg 12. The seat 2 is provided with a first locking member 20, which can lock the seat 2 between the front leg 11 and the rear leg 12. Specifically, in the children's high chair of this embodiment, a seat support 14 is provided on the rear leg 12. The seat support 14 is rotatably mounted on the rear leg 12. The seat support 14 is provided with a locking groove 140, which can be locked into by the first locking member 20. The seat 2 and the seat support 14 are rotatably connected.
[0055] In actual use, when the first locking element 20 is unlocked: the seat plate 2 can be folded onto the support leg 1, and the front leg 11 and the rear leg 12 can rotate and come closer together to fold. That is, when the first locking element 20 is unlocked, the seat plate 2 is unlocked, and the locking effect of the seat plate 2 on the front leg 11 and the rear leg 12 is also released. Therefore, the front leg 11 and the rear leg 12 can rotate relative to each other and fold together. The seat plate 2 and the seat plate bracket 14 will both fold onto the front leg 11 and the rear leg 12. When the children's high chair is in the unfolded state: the seat plate bracket 14 supports the seat plate 2, ensuring the overall support strength of the seat plate 2, and the first locking element 20 is locked into the locking groove 140, and the seat plate 2 is locked between the front leg 11 and the rear leg 12. When the seat plate 2 is locked between the front leg 11 and the rear leg 12, the seat plate 2 cannot be folded. The seat plate 2 limits the front leg 11 and the rear leg 12, and at this time the front leg 11 and the rear leg 12 cannot rotate relative to each other, ensuring the structural stability of the child high chair when it is unfolded, and ensuring the safety of the child sitting in the child high chair.
[0056] In this embodiment of the children's high chair, a second tension spring 21 is provided between the seat plate 2 and the first locking member 20. One end of the second tension spring 21 abuts against the first locking member 20, and the other end abuts against the seat plate 2. The provision of the second tension spring 21 ensures that the first locking member 20 can be reset after unlocking, and ensures that the first locking member 20 can automatically lock into the locking groove 140 after the children's high chair is unfolded, and ensures that the locking of the first locking member 20 is reliable and will not disengage from the locking groove 140, so that the children's high chair remains in the unfolded state.
[0057] In actual use, when the first locking member 20 is pulled to disengage it from the lock groove 140, the second tension spring 21 is compressed. Specifically, in this embodiment, the first locking member 20 is slidably disposed at the bottom of the seat plate 2. The seat plate 2 has a through groove 2A running from top to bottom, and a pull rope 22 is connected to the first locking member 20, passing through the through groove 2A from bottom to top. That is, when it is necessary to unlock the first locking member 20, the pull rope 22 is pulled, and the pull rope 22 causes the first locking member 20 to slide away from the lock groove 140, so that the first locking member 20 disengages from the lock groove 140, the first locking member 20 is unlocked, and the locking of the first locking member 20 to the seat plate 2 is released.
[0058] like Figures 4-6 and combination Figure 9As shown, the tray 3 and backrest 4 are rotatably mounted on the support leg 1, and a second locking member 10 is movably mounted on the support leg 1. The second locking member 10 can lock the tray 3 and backrest 4 onto the support leg 1. When the children's high chair is in the unfolded state, the second locking member 10 locks the tray 3 and backrest 4 onto the support leg 1, specifically onto the rear leg 12 of the support leg 1. At this time, both the tray 3 and backrest 4 are in the unfolded state. When the first locking member 20 is unlocked, the seat 2 is unlocked, and the seat 2 releases the lock on the front leg 11 and the rear leg 12. When the front leg 11 and the rear leg 12 rotate and fold together, the second locking member 10 can be driven to release the lock on the tray 3 and backrest 4. After the tray 3 and backrest 4 are unlocked, they can be folded down.
[0059] Specifically, in this embodiment, the second locking member 10 is configured as a locking gear. The second locking member 10 is movably mounted on the rear leg 12. Several protrusions 121 protrude from the rear leg 12 towards the side closest to the second locking member 10. The second locking member 10 is provided with corresponding slots 101. Specifically, multiple protrusions 121 are provided circumferentially at the joint of the rear leg 12, and the second locking member 10, i.e., the locking gear, is provided with corresponding slots 101. Each of the multiple protrusions 121 corresponds one-to-one with a multiple slot 101. The protrusions 121 are provided with a first inclined wall 121A, and the slots 101 are provided with a second inclined wall 101A. The first inclined wall 121A movably abuts against the second inclined wall 101A. Furthermore, the protrusion 121 can press the second inclined wall 101A through the first inclined wall 121A, causing the second locking member 10 to move away from the protrusion 121, thereby releasing the second locking member 10 from locking the plate 3 and the backrest 4.
[0060] In actual use, when the second locking member 10 locks the plate 3 and the backrest 4 onto the support leg 1: the protrusion 121 is engaged in the slot 101. At this time, the protrusion 121 and the slot 101 are aligned and engaged, so the second locking member 10 is located on the side closer to the rear leg 12. The second locking member 10 locks the plate 3 and the backrest 4 onto the rear leg 12, that is, the plate 3 and the backrest 4 are locked in the display position. When the first locking member 20 is unlocked and the seat plate 2 is unlocked, when the front leg 11 and the rear leg 12 rotate and fold together: the protrusion 121 pushes against the second locking member 10, causing the second locking member 10 to move away from the protrusion 121, releasing the locking of the plate 3 and the backrest 4, and the protrusion 121 disengages from the slot 101. Specifically, when the rear foot 12 rotates, the first inclined wall 121A of the protrusion 121 pushes against the second inclined wall 101A on the second locking member 10, causing the second locking member 10 to move away from the rear foot 12, and the second locking member 10 releases the locking of the plate 3 and the backrest 4.
[0061] In this embodiment, the multiple protrusions 121 on the rear foot 12 correspond one-to-one with the multiple slots 101 on the second locking member 10 (i.e., the locking gear). When the second locking member 10 is in the locked state, the protrusions 121 are engaged in the slots 101 to ensure stable locking. When unlocking, the protrusions 121 press against the second inclined wall 101A on the slot 101 through the first inclined wall 121A, and the protrusions 121 disengage from the slot 101, resulting in smooth and unobstructed unlocking.
[0062] Furthermore, a first tension spring 13 is provided between the backrest 4 and the second locking member 10. One end of the first tension spring 13 abuts against the backrest 4, and the other end abuts against the second locking member 10. When the protrusion 121 pushes against the second locking member 10, unlocking the tray 3 and the backrest 4, the first tension spring 13 is compressed. The first tension spring 13 ensures that the second locking member 10 can quickly reset after unlocking, and ensures reliable locking when the second locking member 10 is locked, preventing accidental locking.
[0063] like Figures 7-9 As shown, the folding principle of the children's high chair in this embodiment is as follows: When the children's high chair is in the unfolded state, both the first locking member 20 and the second locking member 10 are in the locked state. At this time, the tray 3 and the backrest 4 are locked and cannot be folded. At the same time, the seat board 2 is locked, and the seat board 2 limits the front leg 11 and the rear leg 12. That is, the seat board 2 and the front leg 11 and the rear leg 12 cannot be folded at this time. When the folding high chair is needed, the operator pulls the pull cord 22. The pull cord 22 causes the first locking member 20 to slide away from the locking groove 140, disengaging the first locking member 20 from the locking groove 140. The first locking member 20 is unlocked, the seat plate 2 is released, and the seat plate 2 no longer restricts the relative rotation of the front legs 11 and the rear legs 12. The front legs 11 and the rear legs 12 are rotated and folded together, causing the seat plate 2 and the seat plate support 14 to fold as well. The protrusion 121 on the rear legs 12 pushes against the second locking member 10, causing the second locking member 10 to move away from the rear legs 12, thus unlocking the second locking member 10. The second locking member 10 releases its lock on the tray 3 and the backrest 4, allowing the tray 3 and the backrest 4 to be folded up until the high chair is completely folded up. Figure 9 The last image shows the folded state.
[0064] In this design, when the first locking element 20 is unlocked, the seat 2 can be folded onto the support leg 1, and the front leg 11 and rear leg 12 can rotate and come together for folding. During the folding process, the second locking element 10 will be unlocked, releasing the lock on the tray 3 and backrest 4. The backrest 4 and tray 3 can then be folded onto the support leg 1, completing the overall folding of the children's high chair. During the folding process, the user only needs to unlock the first locking element 20 once, and the second locking element 10 can automatically unlock during the folding process. The folding operation is convenient, and the overall space occupied after folding is small.
