Description

Technical Field

[0001] This technical solution relates to the field of children's dining chair technology, specifically a children's dining chair with a rocking function. Background Technology

[0002] A high chair is a special seat designed for infants and toddlers to assist them with eating or feeding. It is usually designed with high legs, equipped with a safety belt or tray, and has a stable structure to prevent tipping.

[0003] For example, Chinese patent CN220988268U discloses an adjustable child seat, including a support frame, a connecting rod, and a seat. A lifting adjustment mechanism is provided between the seat and the connecting rod to adjust the position of the seat on the connecting rod to change the seat height. A locking mechanism is also provided between the seat and the connecting rod to limit the swing of the connecting rod relative to the support frame. The connecting rod also has an unlocking position. When the seat moves relative to the connecting rod to the unlocking position, the locking mechanism can be unlocked, so that the connecting rod can swing relative to the support frame, thereby realizing the integration of a child seat and a cradle, which can be switched by adjusting the seat height.

[0004] In the aforementioned adjustable child seat, the seat moves and changes position along the connecting rod by switching between locking and unlocking. When the seat is moved to the unlocked position, it can be used by swinging. When the child seat is converted to cradle mode, the connecting rod swings freely. Due to the dynamic relative motion, the cross hinge point will repeatedly open and close during the swing. There is a gap between the connecting rod and the two side support frames. Children's fingers may stick into this gap, which may cause a risk of pinching.

[0005] The ends of the connecting rod, the first support frame, and the second support frame are hinged together. The hinged end is connected by a simple stacked hinge (i.e., connected by a single hinge shaft), which results in a large lateral dimension (width) of the hinged end, occupying a lot of space. Furthermore, the swing plane of the connecting rod is located inside the support surface of the first and second support frames, and the swing motion is suspended inside the support structure. The cantilever state leads to insufficient lateral stability, which is not conducive to the stable use of the cradle. The stability is poor and needs to be improved. Utility Model Content

[0006] This technical solution aims to improve the problem that when the existing chair is switched to rocking chair use, the connecting rod is in a cantilever state and the center of gravity of its swing structure is biased towards the inside of the support structure, resulting in poor stability. It provides a children's dining chair with a rocking function.

[0007] The purpose of this technical solution is achieved as follows: A children's high chair with a rocking function includes a seat and a frame. The frame is connected to opposite sides of the seat. The frame includes a first support frame, a second support frame, and a swing frame. The frame is mounted on the swing frame and swings relative to the first and second support frames. The projections of the two side arms of the swing frame along the swing direction are limited to the planar area formed between the first and second support frames.

[0008] Through the above technical solution, when a children's dining chair with a rocking function is used normally, and the seat is switched to a rocking chair with a rocking function, the swing frame swings back and forth between the two support frames. The projection of the swing frame on both sides along its swing direction is always limited to the plane range formed by the first support frame and the second support frame. This ensures that during the swinging process of the swing frame carrying the seat, its center of gravity shift is effectively constrained within the plane range of the support structure. Compared with the original cantilever state where the center of gravity is biased to the inside of the support structure, the overall stability of the rocking use is improved.

[0009] Preferably, the end of the first support frame is provided with a connecting seat, the connecting seat having a connecting plate, and the side of the connecting seat corresponding to the connecting plate having a movable groove. The second support frame is hinged to the first support frame via a hinge shaft. The end of the second support frame is provided with a connecting seat two. The connecting seat two has a connecting plate two, which is embedded in the movable groove. The side of the connecting seat two corresponding to the connecting plate two is formed with a movable groove two. The groove depth of the movable groove two is less than the groove depth of the movable groove one. The swing frame has a movable disc extending from its end. The movable disc is embedded in the movable groove 2, and the movable disc makes way for the positions of the connecting disc 1 and the connecting disc 2.

[0010] Through the above technical solution, the connecting plate 2 is embedded in the movable groove 1 to form the first layer of connection. At this time, a planar area can be formed between the first support frame and the second support frame. The movable plate at the end of the swing frame is embedded in the movable groove 2 with a smaller groove depth on the connecting seat 2 of the second support frame to form the second layer of connection. The movable plate makes way for the connecting plate 1 and the connecting plate 2. The hinge ends of the three frames fit tightly, so that the chair frame has a narrower width.

[0011] Preferably, the shape of the connecting disk two and the movable disk corresponding to the movable groove one corresponds to the movable groove one, and the stacking thickness of the connecting disk two and the movable disk is adapted to the groove depth of the movable groove one.

[0012] Through the above technical solution, the connecting plate 2 and the movable plate and the movable groove 1 form a precise multi-layered interlocking structure, which reduces the radial movement of the swing frame during swinging, reduces the overall width of the three plates stacked together, and makes the first support frame, the second support frame and the swing frame on the same side on the same plane, thus having good stability.

[0013] Preferably, the chair frame is provided with a cover, the cover has a cavity, and the connecting seat one, connecting seat two and the movable plate are all embedded in the cavity.

[0014] Through the above technical solution, the cover encloses the connecting seat 1, connecting seat 2 and the movable plate entirely within its cavity. The opening size of the cavity covers the movement stroke of the swing frame and the maximum support range of the two side support frames. Physical isolation reduces external interference and avoids the risk of pinching when hands are inserted into the interlocking gaps, thus improving protection and safety.

[0015] Preferably, the connecting plate 2 has an assembly groove 1 on one end face away from the movable groove 2, and the assembly groove 1 has a set of matching grooves 1 along its circumferential inner wall. The connecting plate 1 has a corresponding assembly groove 2, and the assembly groove 2 has at least two sets of matching grooves 2 along its circumferential inner wall. The assembly groove 1 and the assembly groove 2 are fitted with shaft limiting discs, and the shaft limiting discs are provided with assembly blocks for embedding the matching grooves 1 and the corresponding matching grooves 2. Both the first and second connecting seats are provided with arc-shaped grooves, and two pins extend from the inner sidewall of the cover, with each pin corresponding to one of the two arc-shaped grooves.

[0016] Through the above technical solution, the first support frame and the second support frame are fully unfolded, and the ends of the connecting seat one and the connecting seat two abut against each other to form a rigid limit; when the two support frames need to approach each other around the hinge axis, the arc direction of the arc groove is precisely matched with the hinge rotation trajectory, and the corresponding pin of the arc groove avoids the pin until the support frame is fully folded and the pin reaches the other end of the groove, providing further limit protection.

[0017] The two sides of the shaft limiting disc are respectively embedded in the first and second assembly slots. The assembly blocks are embedded one-to-one in the first matching slot. The other side of the assembly block can be selected to be fitted into different sets of the second matching slots. By changing the assembly block embedded in different sets of the second matching slots, the assembly position of the shaft limiting disc can be switched between the first position and the second position. When the shaft limiting disc is assembled in the first position, the first support frame and the second support frame can be unfolded to support the ground. When the shaft limiting disc is assembled in the second position, the first support frame and the second support frame move closer to each other and fold together, realizing the folding and storage of the overall structure, effectively reducing the volume and facilitating transportation or storage.

[0018] Preferably, two lifting adjustment mechanisms are provided between the seat and the swing frame. These mechanisms can switch between a locked state and an unlocked state. Each lifting adjustment mechanism includes: An adjusting sleeve is slidably fitted onto the swing frame, the adjusting sleeve has a mounting groove, and the seat is hinged to the adjusting sleeve; An adjustment button is installed in the mounting groove and hinged to the adjustment sleeve. One end of the adjustment button is provided with a snap-fit ​​block, and the bottom of the mounting groove is provided with a clearance hole for the snap-fit ​​block to pass through. The elastic element has two ends that abut against the adjustment button and the bottom of the mounting groove, respectively. The swing frame has a snap-fit ​​hole along its length. The snap-fit ​​block is fitted into different snap-fit ​​holes. The elastic force of the elastic element pushes the snap-fit ​​block to fit into the snap-fit ​​hole, so that the lifting adjustment mechanism is in a locked state, locking the seat and the swing frame.

[0019] With the above technical solution, when the seat height needs to be adjusted, pressing the adjustment buttons on both sides causes them to rotate around the hinge point and compress the elastic element, causing the locking block to disengage from the locking hole of the current swing frame. At this time, the lifting adjustment mechanism is in the unlocked state, and the adjustment sleeve can slide freely along the swing frame. The seat changes its height position synchronously. When the seat moves to the desired position, the locking block needs to be aligned with the corresponding locking hole. After releasing the adjustment buttons on both sides, the elastic element pushes the locking block to automatically embed into the corresponding locking hole, and the lifting adjustment mechanism is in the locked state. The design, through the linear operation logic of pressing-sliding-releasing and the multi-level locking hole spacing layout, ensures that the seat has multiple adjustment levels. The elastic self-locking mechanism improves the smoothness of adjustment and the stability of locking, and improves the convenience of operation.

[0020] Preferably, the second support frame is provided with a locking assembly, the locking assembly comprising: A locking sleeve is disposed on the second support frame; A locking bar is rotatably mounted on the locking sleeve. The locking bar has a locking groove, and the locking groove has an opening that passes through the side of the locking block along the rotation direction. A clearance groove is provided on the side wall of the locking groove, and the clearance groove connects the locking groove to the outside. A locking block is disposed on the swing frame. The locking block has a protruding ring portion, and the locking block uses a relief groove to allow the protruding ring portion to be inserted into the locking groove through an opening.

[0021] With the above technical solution, when the seat needs to be adjusted to a locked state where it cannot rock, the swing lever is rotated close to the second support frame, and the locking lever is rotated so that its opening is aligned with the locking block. The convex ring of the locking block is inserted into the locking groove through the opening, and the locking block passes through the clearance groove accordingly to complete the mechanical locking. The convex ring abuts against the inner wall of the locking groove to restrict the swing of the swing lever. When unlocking, the locking lever is rotated in the opposite direction to make the convex ring come out of the opening again, thus separating the seat and realizing the switching between the sitting and rocking usage states. The operation is convenient.

[0022] Preferably, the seat is provided with an angle adjustment mechanism, the angle adjustment mechanism comprising: A movable gear lever is disposed on the seat, the seat having a sliding groove, and the movable gear lever is slidably confined within the sliding groove; Two movable levers are respectively located on the symmetrical sides of the movable gear lever, one end of each lever is connected to the movable gear lever, and the other end has a locking part; The adjustment assembly includes an adjustment rod and an adjustment elastic member. One end of the adjustment rod is engaged with a locking part, and the other end has a fixed pin protruding from it. The seat has a stop block protruding from it. The adjustment elastic member is confined within the stop block, and both ends of the adjustment elastic member abut against the stop block and the fixed pin, respectively. The adjusting sleeve has at least two fixed holes. The elastic force of the adjusting elastic element makes the fixed pin tend to be embedded in the fixed hole. When the movable shift lever slides, it drives the movable rods on both sides, and the movable rods drive the fixed pin of the adjusting rod to disengage from the fixed hole.

[0023] With the above technical solution, during adjustment, the movable gear lever is manually pressed and slid along the sliding groove. The movable gear lever drives the movable rods on both sides to move closer to each other. The movable rods drive the corresponding adjustment rods to move through the locking part. Based on the fixed position of the stop block, the fixed pin compresses the adjustment elastic element, and the fixed pin disengages from the fitted fixed hole. The seat can be unlocked and rotated freely. When switching to another fixed hole, the movable gear lever is released, and the adjustment elastic element automatically pushes the fixed pin back into the new gear hole, thereby realizing the seat angle adjustment.

[0024] Preferably, the seat has a protruding baffle portion, the baffle portion is formed with a guide groove, and the movable rod is fitted into the guide groove; The sliding groove is provided with an orientation groove, the movable rod has a defined end for embedding into the orientation groove, the inner side of the movable shift lever is provided with a guide groove, the inner sidewalls of the guide groove along the sliding direction of the movable shift lever are all inclined sidewalls, the defined end protrudes with a guide protrusion for embedding into the guide groove, the movable shift lever pushes against the guide protrusion through the inclined sidewall, thereby driving the movable rod to slide along the guide groove.

[0025] The above technical solution uses guide grooves and directional grooves to fit with the movable rod, limiting its reciprocating movement direction and ensuring that the positioning pin is inserted into the positioning hole in an axial vertical posture, reducing angle and position deviations, eliminating the need for repeated adjustments, and providing good linkage and insertion accuracy.

[0026] Preferably, the adjusting sleeve has a rotation limiting part protruding towards the bottom of the seat; The seat is equipped with a pedal, which is hinged to the seat, and the pedal can change its rotation angle relative to the seat by adjusting the structure. The seat is equipped with a table and has two armrests hinged to it. The two armrests are located on opposite sides of the seat. The table is detachably connected to the two armrests via a quick-release mechanism.

[0027] Through the above technical solution, the upper edge of the rotation limiting part can abut against the bottom of the seat, limiting the excessive rotation of the seat and ensuring that the degree of adjustment is within the normal range; the pedal can be placed for the child's feet, the pedal can be flipped for use or folded up, and the table can be used for the child to eat.

[0028] The key and beneficial technical effects of this technical solution compared to existing technologies are: 1. This technical solution uses a swing frame that is oscillating on the first support frame and the second support frame. The projection of the two side arms of the swing frame along the swing direction is limited to the plane interval formed between the first support frame and the second support frame, which effectively constrains the center of gravity offset, improves the anti-sway capability of the rocking chair mode, and improves the stability of the rocking chair state.

[0029] 2. This technical solution uses a multi-layer nested connection, with the second connecting plate embedded in the first movable groove and the movable plate embedded in the second movable groove. The movable plate makes room for the positions of the first and second connecting plates. The stacking thickness of the second connecting plate and the movable plate is adapted to the groove depth of the first movable groove. The hinge ends of the three frames are tightly fitted together, thus giving the chair frame a narrower width.

[0030] 3. This technical solution features a cover on the chair frame. The cover encloses the connecting seat one, connecting seat two, and movable plate through a cavity. The opening of the cavity covers the swing frame's travel range and the maximum unfolding range of the support frame. Physical isolation reduces external interference, avoids the risk of pinching injuries from hands probing into the interlocking gaps, and improves protection and safety. Attached Figure Description

[0032] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0033] Example: See Figure 1 and Figure 6 A children's high chair with a rocking function, which can be switched between a high chair and a rocker, includes a seat 1 and a frame 2. The seat 1 has a seat for a toddler, and a cushion can be laid on the inside of the seat 1. A footrest 34 and a table 35 are installed on the front of the seat 1. The table 35 is positioned above the footrest 34 and can be used to place food. The seat 1 has two armrests 47 hinged to it, which are located on opposite sides of the seat 1. The table 35 is detachably connected to the two armrests 47 via a quick-release structure. The detachable table 35 is prior art and will not be described in detail here. Figure 1 As shown, when using the rocking chair, the table 35 needs to be removed from the armrests 47 on both sides; the footboard 34 is hinged to the seat 1, and the footboard 34 changes its angle relative to the seat 1 by adjusting the structure, so that the footboard 34 can be flipped and limited to a specific tilt angle to support the child's legs.

[0034] See Figure 2 , Figure 3 and Figure 4 The chair frame 2 is connected to the opposite sides of the seat 1. The chair frame 2 includes a first support frame 21, a second support frame 22, and a swing frame 23. The three frames are all U-shaped. The first support frame 21 is located at the rear of the second support frame 22. The upper ends of the two support frames are hinged to each other, and the lower ends are matched to provide stable support on the horizontal ground. The hinge of the first support frame 21 and the second support frame 22 is achieved by the first support frame 21 having a connecting seat 31. Each of the two arm ends of the first support frame 21 has a connecting plate 41. The connecting seat 31 has a movable groove 51 formed on the inner side of the connecting plate 41 near the seat 1. The two arm ends of the second support frame 22 also have two connecting seats 32. Each connecting seat 32 has a connecting plate 42, the size of which is adapted to the movable groove 51, so that the connecting plates 41 on both sides are embedded into the movable grooves 51 on both sides. The hinge is achieved by the hinge passing through the connecting plates 41 and the connecting plates 42.

[0035] The connecting plate 2 42 has an assembly groove 391, which is located on the side of the connecting plate 2 42 near the connecting plate 1 41. The assembly groove 391 also has a set of locking grooves 401 along the circumferential direction, which includes two grooves. The two grooves are symmetrically arranged along the hinge axis between the first support frame 21 and the second support frame 22, and are respectively connected to the opposite side wall of the assembly groove 391. Correspondingly, the connecting plate 1 41 has an assembly groove 392, which is formed on the bottom of the movable groove 51. The assembly groove 392 has at least two sets of locking grooves 402 along the circumferential direction. The layout of the locking grooves 402 is similar to that of the locking grooves 401. When the connecting plate 1 41 and the connecting plate 2 42 are connected, the positions of the assembly grooves 392 and the assembly grooves 391 can be spliced ​​to form a complete assembly groove, so that the shaft limiting plate 43 is embedded in both the assembly grooves 391 and the assembly grooves 392. The shaft limiting plate 43 has symmetrically protruding assembly blocks 44 on both sides.

[0036] When the shaft limiting disk 43 is assembled, one side of it is first inserted into the first mounting groove 391. At this time, the mounting blocks 44 on both sides are inserted into the first matching grooves 401 on both sides respectively. The other side of the mounting block 44 is selected with different groups of matching grooves 402 and then close together for fitting. The hinge shaft 49 passes through the first connecting disk 41, the shaft limiting disk 43 and the second connecting disk 42 in sequence. The shaft limiting disk 43 is provided with a bearing 50 sleeved on the corresponding hinge shaft 49. The hinge shaft 49 is guided to rotate by the bearing 50. By changing the group of matching grooves 402 into which the mounting block 44 is inserted, different fitting angles between the first support frame 21 and the second support frame 22 can be achieved. This embodiment shows the situation where the assembly position of the shaft limiting disk 43 is switched between the first position and the second position. When the shaft limiting disk 43 is assembled in the first position, the first support frame 21 and the second support frame 22 are opened and the two support frames can be supported on the ground.

[0037] See Figure 12 When the shaft limiting disk 43 is assembled in the second position, the first support frame 21 and the second support frame 22 move closer to each other and fold together, realizing the folding and storage of the overall structure, effectively reducing the storage volume and making it easy to transport or store.

[0038] Movable discs 6 are installed at the ends of both side arms of the swing frame 23. Connecting seat 2 32 has a movable groove 2 52 located on the side of connecting disc 2 42 opposite to the locking groove 1 401. The size of the movable disc 6 matches the movable groove 2 52. The movable disc 6 provides clearance for the positions of connecting disc 1 41 and connecting disc 2 42. The movable disc 6 is embedded in the movable groove 2 52 and is passed through by a hinge shaft. The stacking thickness of connecting disc 2 42 and movable disc 6 matches the groove depth of movable groove 1 51. Figure 5 As shown, the two side arms of the first support frame 21 and the second support frame 22 are arranged opposite each other to form a planar interval. The two side arms of the swing frame 23 are exactly within the planar interval on both sides, that is, the projection of the swing frame 23 on both sides along the swing direction is limited to the planar interval. The swing of the swing frame 23 can positively contact and approach the first support frame 21 and the second support frame 22.

[0039] See Figure 5 Two lifting adjustment mechanisms 9 are provided between the seat 1 and the swing frame 23. Each lifting adjustment mechanism 9 includes an adjustment sleeve 91, an adjustment button 92, and an elastic element 93. The adjustment sleeve 91 is sleeved on the side rod of the swing frame 23 and is hinged to the seat 1. The adjustment sleeve 91 slides along the swing frame 23, and its sliding direction corresponds to the direction of the side rod. The swing frame 23 has a number of snap-fit ​​holes 13, which are distributed at intervals along the length of the side rod of the swing frame 23. The adjustment sleeve 91 has a mounting groove 10, and the bottom of the mounting groove 10 has a clearance hole 12. The position of the clearance hole 12 can be aligned with any snap-fit ​​hole 13.

[0040] The adjustment button 92 is installed in the mounting groove 10 and is hinged to the adjustment sleeve 91, so that it swings within the mounting groove 10. The adjustment button 92 can be switched between the open and closed states by pressing. The elastic element 93 is preferably a spring, with one end abutting against the bottom of the mounting groove 10 and the other end abutting against the corresponding rear end of the adjustment button 92. The adjustment button 92 is provided with a locking block 11, which is fixed to the front end of the adjustment button 92 away from the elastic element 93. The locking block 11 can pass through the relief hole 12. The elastic force of the elastic element 93 pushes the adjustment button 92 to rotate, so that the locking block 11 has a tendency to protrude outward from the relief hole 12.

[0041] During use, both lifting and adjusting mechanisms 9 on both sides need to be operated simultaneously. By pressing the adjustment button 92 on one side where the elastic element 93 is located, the adjustment button 92 drives the locking block 11 to move. The locking block 11 retracts into the clearance hole 12, disengaging from the corresponding locking hole 13. At this time, the lifting and adjusting mechanism 9 is in the unlocked state, and the adjusting sleeve 91 slides freely along the swing frame 23 to adjust the seat. When the lifting and adjusting mechanism 9 is switched to the locked state, the elastic element 93 is released, and the elastic element 93 pushes the adjustment button 92 to reset. The adjustment button 92 drives the locking block 11 to move, and the locking block 11 is inserted into the corresponding locking hole 13, thereby limiting the adjusting sleeve 91. When the seat 1 is in the lower locked position, it can be used for rocking.

[0042] See Figure 6 , Figure 7 and Figure 8 The second support frame 22 is provided with locking components 14, two of which are provided corresponding to the two arms of the second support frame 22. Each locking component 14 includes a locking sleeve 141, a locking bar 142, and a locking block 143. The locking sleeve 141 is fitted and fixed on the arm corresponding to the second support. The locking bar 142 is rotatably connected to the outside of the locking sleeve 141. The locking block 143 protrudes and is fixed to the outside of the corresponding arm of the swing frame 23. The locking block 143 has a protruding ring portion 18, which protrudes from the end of the locking block 143 away from the support frame. The locking bar 142 has a locking groove 15, which has an opening 16 on the side of the locking block 143 along the rotation direction. The size of the opening 16 is adapted to the size of the protruding ring portion 18. The locking groove 15 also has a relief groove 17, which connects the locking groove 15 to the outside, and the end facing the opening 16 is also through.

[0043] By rotating the swing frame 23 closer to the second support frame 22, the locking bars 142 on both sides, the locking grooves 15 of each locking bar 142 are aligned with the locking blocks 143 for fitting, the protruding rings 18 are embedded in the locking grooves 15, and the clearance grooves 17 provide clearance, so that the locking blocks 143 abut against the groove walls of the locking grooves 15 along the swing direction of the swing frame 23, thereby achieving relative locking between the swing frame 23 and the second support frame 22, and eliminating the rocking use of the seat 1.

[0044] See Figure 9 , Figure 10 and Figure 11 The seat 1 is equipped with an angle adjustment mechanism 19, which includes a movable gear lever 191, two movable rods 192, and an adjustment component 193. A sliding groove 20 is provided at the bottom of the seat 1. The inner side of the movable gear lever 191 is embedded in the sliding groove 20, and the outer side of the movable gear lever 191 is exposed in the sliding groove 20. In this embodiment, the outer side is shown to have a handle-like shape. The movable gear lever 191 slides back and forth along the sliding groove 20, and its sliding direction is perpendicular to the hinge axis of the swing frame 23. The two movable rods 192 are respectively movably connected to the opposite sides of the movable gear lever 191 along the sliding direction, and their moving direction is perpendicular to the sliding direction of the movable gear lever 191. The other end of the two movable rods 192 is provided with a locking part 48. The movable gear lever 191 can drive the two movable gear levers 191 on both sides to move relatively closer or further apart.

[0045] The seat 1 is also provided with a stop block 38. The adjustment component 193 is limited within the stop block 38. The adjustment component 193 includes an adjustment rod 1931 and an adjustment elastic element 1932. In this embodiment, the stop block 38 is shown to have a chamber with through holes at both ends. One end of the adjustment rod 1931 passes through the through hole and engages with the locking part 48 of the movable rod 192, and the other end protrudes with a fixing pin 27. The adjustment elastic element 1932 is sleeved on the adjustment rod 1931. One end of the elastic element abuts against the rear end of the fixing pin 27, and the other end abuts against the corresponding inner wall of the chamber of the stop block 38. The adjustment sleeve 91 has at least two fixing holes 28. The elastic force of the adjustment elastic element 1932 pushes the adjustment rod 1931, so that the fixing pin 27 tends to slide and fit into the fixing hole 28.

[0046] Each adjusting sleeve 91 has a rotation limiting part 33 that protrudes toward the bottom of the seat 1.

[0047] The two fixed holes 28 correspond to two different adjustment angles of the seat 1. The seat 1 can be switched between the first adjustment angle and the second adjustment angle. When the seat 1 is in the first adjustment angle, it is used as a rocking chair. When in use, by moving the movable lever 191, the movable lever 191 simultaneously drives the movable rods 192 on both sides to move. The two movable rods 192 respectively pull the two adjustment rods 1931 to move synchronously. The fixed pin 27 compresses the adjustment elastic element 1932, and the fixed pin 27 disengages from the corresponding fixed hole 28. At this time, the seat 1 can be rotated to adjust the angle. After the seat is flipped forward to switch to the second adjustment angle, the fixed pin 27 is aligned with the other fixed hole 28. The movable lever 191 is released, and the adjustment elastic element 1932 pushes the fixed pin 27 into the fixed hole 28. The seat can then be used as a dining chair.

[0048] The specific work process of this plan is as follows: This technical solution uses a connecting plate 2 42 embedded in a movable slot 1 51 for the first layer of connection. At this time, a planar area can be formed between the first support frame 21 and the second support frame 22. The movable plate 6 at the end of the swing frame 23 is embedded in a movable slot 2 52 with a smaller groove depth on the connecting seat 2 32 of the second support frame 22 for the second layer of connection. The movable plate 6 makes way for the connecting plate 1 41 and the connecting plate 2 42. When the seat 1 needs to switch to the rocking chair function, the swing frame 23 can swing relative to the second support frame 22. The projection of the swing frame 23 on both sides along its swing direction is always limited to the planar area formed by the first support frame 21 and the second support frame 22. This ensures that during the swing of the swing frame 23 carrying the seat 1, its center of gravity shift is effectively constrained within the planar area of ​​the support structure, avoiding the problem of the center of gravity shifting to the inside of the support structure in the original cantilever state, thereby improving the overall stability of the rocking chair during use.

[0049] Example 2: See Figure 12 and Figure 13 A children's high chair with a rocking function differs from Embodiment 1 in that the seat 1 is provided with a baffle portion 29, which includes multiple baffle portions 29. The multiple baffle portions 29 are mutually clamped to form a guide groove 30. The rod body of the movable rod 192 is embedded in the guide groove 30. A directional groove 45 is formed in the sliding groove 20. The groove of the directional groove 45 is set in the sliding direction corresponding to the movable rod 192. One end of the movable rod 192 is provided with a limiting end 46, which is embedded in the directional groove 45. The limiting end 46 is provided with a guide protrusion 26, which protrudes from the side end face of the limiting end 46 away from the bottom of the directional groove 45. The movable lever 191 is provided with a guide groove 24 on its inner side for the guide protrusion 26 to be embedded. The guide groove 24 has an inclined sidewall 25 on the opposite inner sidewall along the sliding direction of the movable lever 191. The sliding of the movable lever 191 uses the inclined sidewall 25 to drive the movable rods 192 on both sides to move closer or further away.
