Description

Technical Field

[0001] This utility model relates to the field of dining chair technology, and in particular to a children's dining chair. Background Technology

[0002] The main purpose of a children's high chair is to make it easier for children to eat. Its structure mainly includes a chair frame and a plate.

[0003] To make it easier to lift a child out of and put a child back in the high chair, the tray of the high chair is usually designed to rotate inwards and outwards. When a child gets in or out of the high chair, the tray can be rotated outwards.

[0004] The existing children's high chair with a rotating tray has the tray movably mounted on the armrests on both sides of the chair frame. When the tray is rotated outward, the armrests remain stationary, and the tray rotates outward relative to the armrests to open. Its structure is complex and has many parts. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the technical problem to be solved by this utility model is to propose a children's dining chair with a simple structure and convenient operation of rotating tray.

[0006] The technical solution adopted by this utility model to solve its technical problem is to propose a children's dining chair, comprising:

[0007] A chair frame, wherein the chair frame is provided with an opening for a child to enter and exit, and a first armrest and a second armrest are respectively provided on both sides of the chair frame near the opening. The first armrest has a vertical rotation center and can rotate inward and outward along the vertical rotation center.

[0008] A locking mechanism is provided on the first armrest, including a locking member that can be locked to the chair frame to restrict the inward and outward rotation of the first armrest;

[0009] The plate is detachably mounted on the first and second armrests;

[0010] When the plate is placed on the first armrest: the plate unlocks the locking device, thereby releasing the locking device from limiting the inward and outward rotation of the first armrest; and the inward and outward rotation of the first armrest can drive the plate to rotate inward and outward at the opening.

[0011] Furthermore, the locking mechanism includes an unlocking module, which is movably disposed on the first handrail;

[0012] When the plate is placed on the first armrest, the plate pushes against the unlocking module, thereby unlocking the locking mechanism.

[0013] Furthermore, the unlocking module includes a slide block and an unlocking component. The slide block is slidably disposed in the first armrest and is connected to the locking component by a cable. The unlocking component is disposed on the slide block and can drive the slide block to slide.

[0014] Furthermore, the unlocking element extends at least partially from the first handrail.

[0015] Furthermore, the slide block is provided with an inclined groove that is inclined relative to its sliding direction, and the unlocking member is provided with a protrusion that extends into the inclined groove;

[0016] The first armrest is provided with a mounting groove, and the unlocking member is retractably and movably disposed in the mounting groove, and the direction of the retracting and extending movement of the unlocking member is perpendicular to the direction of the sliding of the slide block.

[0017] Furthermore, the first handrail is provided with a guide groove along its length, and the unlocking member at least partially protrudes from the guide groove;

[0018] The plate is provided with a guide strip. When the plate is mounted on the first armrest, the guide strip passes into the guide groove and pushes against the unlocking member.

[0019] Furthermore, the first armrest includes a mounting base disposed at one end thereof, the mounting base being rotatably mounted on the chair frame, and its rotation center being the vertical rotation center;

[0020] The chair frame is provided with a locking groove. When the locking member is locked into the locking groove, the locking member restricts the rotation of the mounting base.

[0021] Furthermore, the chair frame is provided with an arc-shaped groove along the circumference of the vertical rotation center, and the mounting base has a protrusion that extends into the arc-shaped groove;

[0022] The protrusion restricts the rotation range of the mounting base by abutting against both ends of the arc-shaped groove.

[0023] Furthermore, both the first and second handrails are equipped with slots;

[0024] The plate is equipped with a locking mechanism and a limiting component. The locking mechanism includes a first locking seat, a second locking seat, and an unlocking control component. The first locking seat, the second locking seat, the limiting component, and the unlocking control component are all movably disposed on the plate. When the plate is mounted on the first armrest and the second armrest, the first locking seat and the second locking seat are respectively locked into the locking slots of the first armrest and the second armrest, and the limiting component protrudes from the side of the second armrest, preventing the plate from detaching from the side of the second armrest. The unlocking control component can drive the first locking seat and the second locking seat to detach from the locking slots, and the limiting component can drive the second locking seat to detach from the locking slot on the second armrest.

[0025] Furthermore, both the first and second handrails are provided with multiple slots along their length; the first and second slots can be engaged in the slots at different positions, so that the plate is held at different positions on the first and second handrails.

[0026] When the limiting member is released from its position on the plate, the limiting member causes the second card holder to disengage from the slot on the second armrest, and the plate rotates as the first armrest rotates inward and outward.

[0027] Compared with the prior art, the present invention has at least the following beneficial effects:

[0028] In this invention, when the tray is not installed, the locking mechanism locks the locking element to the chair frame, restricting the inward and outward rotation of the first armrest. When the tray is installed on the first armrest, the tray unlocks the locking element, releasing the restriction on the inward and outward rotation of the first armrest. When the first armrest rotates inward and outward, the first armrest can drive the tray to rotate inward and outward accordingly, thereby controlling the opening and closing of the opening on the chair frame, rather than the tray itself rotating relative to the first armrest. The structure for realizing the tray's rotation is simple, which simplifies the structure of the dining chair, and the overall structure of the tray is also simpler.

[0029] In this invention, when the tray is installed on the first and second armrests, the first and second retaining seats respectively engage in the slots of the first and second armrests, and the limiting member protrudes from the side of the second armrest, limiting the tray and ensuring that it will not fall off the chair frame during use, thus ensuring good structural stability. When it is necessary to rotate the tray inward or outward, the limiting member is driven to release its restraint, and the limiting member will cause the second retaining seat to disengage from the slot on the second armrest. At this time, the first retaining seat does not disengage from the slot on the first armrest, ensuring reliable fixation between the tray and the first armrest. Rotating the first armrest inward or outward will cause the tray to rotate inward or outward, making the operation simple.

[0030] In this utility model, multiple slots are provided on both the first and second armrests. When the unlocking control is activated, the first and second slots are disengaged from the slots on the first and second armrests, respectively, allowing the plate to be pulled back and forth for adjustment. After adjustment, the first and second slots are re-engaged into the slots on the first and second armrests, ensuring that the plate can be held at different positions on the first and second armrests.

[0054] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0055] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0056] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0058] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0059] Combination Figures 1-3 as well as Figures 9-10As shown in the figure, the children's high chair in this embodiment mainly includes: a chair frame 1 and a tray 3. The first armrest 11 of the chair frame 1 is equipped with a locking mechanism 2, and the tray 3 is equipped with a locking mechanism 30 and a limiting member 34. The chair frame 1 has an opening 100 for children to enter and exit. This opening 100 is located on the front side of the chair frame 1, allowing adults to place children into and remove them from the high chair through the opening 100. A first armrest 11 and a second armrest 12 are respectively arranged on both sides of the chair frame 1 near the opening 100. In the accompanying drawings of this embodiment, the second armrest 12 is located on the left side of the chair frame 1, and the first armrest 11 is located on the right side of the chair frame 1. The first armrest 11 has a vertical rotation center, and the first armrest 11 can rotate inward and outward along this vertical rotation center. Specifically, the first armrest 11 is hinged to the chair frame 1 via a central shaft 13, which is configured as the vertical rotation center. A locking mechanism 2 is installed on the first armrest 11 and includes a locking element 21, which can be optionally a locking pin. The locking element 21 can be locked to the chair frame 1, restricting the inward and outward rotation of the first armrest 11. A tray 3 is detachably mounted on the first armrest 11 and the second armrest 12. When the tray 3 is installed on the first armrest 11: the tray 3 unlocks the locking element 21, releasing the locking element 21 from restricting the inward and outward rotation of the first armrest 11; and the inward and outward rotation of the first armrest 11 can cause the tray 3 to rotate inward and outward at the opening 100. That is, when the tray 3 is not installed, the first armrest 11 is in a state restricted by the locking element 21 and cannot rotate inward or outward. However, after the tray 3 is installed on the first armrest 11, it forces the locking element 21 to release the restriction on the inward and outward rotation of the first armrest 11. When the first armrest 11 rotates inward and outward, the tray 3 can rotate inward and outward along with the inward and outward rotation of the first armrest 11.

[0060] When a child needs to get in or out of the high chair, the first armrest 11 can be rotated outwards, causing the tray 3 to open outwards from the opening 100, making it easy for the child to get in and out of the high chair. During normal use of the high chair, the tray 3 is fixed to the first armrest 11 and the second armrest 12, blocking the opening 100, allowing the child to eat on the tray 3.

[0061] In this embodiment, when the tray 3 is not installed, the locking element 21 in the locking mechanism 2 locks onto the chair frame 1, restricting the inward and outward rotation of the first armrest 11 and ensuring the normal function of the armrest. When the tray 3 is installed on the first armrest 11, the tray 3 unlocks the locking element 21, releasing the restriction on the inward and outward rotation of the first armrest 11, allowing the tray 3 to rotate inward and outward with the first armrest 11. When the first armrest 11 rotates inward and outward, the first armrest 11 can drive the tray 3 to rotate inward and outward accordingly, thereby controlling the opening and closing of the opening 100 on the chair frame 1. In existing structures, the inward and outward rotation of the tray 3 is relative to the armrest, which is complex in structure and has many parts, and the structure of the tray 3 is also relatively complex. In this embodiment, the inward and outward rotation of the first armrest 11 drives the inward and outward rotation of the tray 3, rather than the tray 3 rotating inward and outward relative to the first armrest 11. In this embodiment, the structure for the rotation of the tray 3 is simple, that is, the structure of the chair can be simplified, and the overall structure of the tray 3 is simpler.

[0062] like Figures 7-10 As shown, the locking mechanism 2 in this embodiment includes an unlocking module, which is movably mounted on the first armrest 11. When the tray 3 is mounted on the first armrest 11, the tray 3 pushes against the unlocking module, causing the locking member 21 to unlock. The unlocking module is connected to the locking member 21. When the tray 3 is mounted on the first armrest 11, the tray 3 pushes against the unlocking module, thereby driving the locking member 21 to unlock from the chair frame 1, no longer restricting the inward and outward rotation of the first armrest 11.

[0063] As a preferred embodiment, the unlocking module includes a slide block 22 and an unlocking member 23. The slide block 22 is slidably disposed in the first handrail 11, specifically, the slide block 22 can slide along the length direction of the first handrail 11, and the slide block 22 is connected to the locking member 21 by a cable 24. The unlocking member 23 is disposed on the slide block 22, and the unlocking member 23 can drive the slide block 22 to slide. Specifically, the slide block 22 is provided with an inclined groove 220 that is inclined relative to its sliding direction, and the unlocking member 23 is provided with a protrusion 230 that extends into the inclined groove 220. The side of the first handrail 11 is provided with a mounting groove 111A, and the unlocking member 23 is telescopically disposed in the mounting groove 111A, and the telescopic movement direction of the unlocking member 23 is perpendicular to the sliding direction of the slide block 22, that is, the telescopic movement direction of the unlocking member 23 is perpendicular to the length direction of the first handrail 11, thus the unlocking module changes the power transmission direction. When the tray 3 is installed on the first armrest 11, the tray 3 drives the unlocking component 23 to retract inward. The unlocking component 23 then moves the slide 22 forward. The slide 22 pulls the locking component 21 via the cable 24, unlocking the locking component 21 from the chair frame 1. Both the unlocking component 23 and the locking component 21 are equipped with return springs, ensuring that the unlocking component 23 and the locking component 21 can be reset in a timely manner.

[0064] Of course, the unlocking module can also be implemented in other ways, such as: the slide 22 and the unlocking component 23 are made into a whole component. When the plate 3 is installed on the first armrest 11, by setting inclined surfaces on both the plate 3 and the unlocking module, the inclined surfaces squeeze each other, and the plate 3 squeezes the whole unlocking module, so that the unlocking module moves forward along the length of the first armrest 11, pulls the locking component 21, and unlocks the locking component 21 from the chair frame 1.

[0065] Specifically, in this embodiment, the unlocking member 23 extends at least partially from the first armrest 11, facilitating the plate 3 to push against the unlocking member 23 when it is installed on the first armrest 11. Alternatively, if the plate 3 is not installed, the user can press the protruding part of the unlocking member 23 with their hand or other tools, which will also unlock the locking member 21, making it convenient to use. Further specifically, the first armrest 11 has a guide groove 111B along its length. This guide groove 111B is an elongated groove formed on the side of the first armrest 11, and the unlocking member 23 protrudes at least partially from the guide groove 111B. A guide strip 330 is provided on the plate 3. When the plate 3 is mounted on the first armrest 11, the guide strip 330 passes through the guide groove 111B from the end of the armrest, and pushes against the unlocking member 23, causing the unlocking member 23 to retract. The unlocking member 23 drives the slide 22 to move forward, and the slide 22 pulls the locking member 21 through the cable 24, thereby unlocking the locking member 21. The cross-section of the guide groove 111B and the guide strip 330 is preferably rectangular. The combination of the guide groove 111B and the guide strip 330 can also play a guiding role when the plate 3 is extended and retracted, and can also ensure that the plate 3 does not wobble up and down during rotation.

[0066] In this embodiment, the first armrest 11 includes a mounting base 110 disposed at one end and an armrest body 111. The mounting base 110 is rotatably mounted on the chair frame 1, and its rotation center is the vertical rotation center. That is, the mounting base 110 is mounted on the chair frame 1 and can rotate inward and outward relative to the vertical rotation center (central axis 13). The inward and outward rotation of the mounting base 110 causes the first armrest 11 to rotate inward and outward as a whole. A locking groove 10 is provided on the chair frame 1. When the locking member 21 is locked into the locking groove 10, the locking member 21 restricts the rotation of the mounting base 110. When the locking member 21 is unlocked, that is, the locking member 21 disengages from the locking groove 10. Furthermore, an arc-shaped groove 14 is provided on the chair frame 1 along the circumference of the vertical rotation center. The arc-shaped groove 14 is opened with the vertical rotation center as the center. The mounting base 110 has a protrusion 110A that extends into the arc-shaped groove 14. The protrusion 110A abuts against both ends of the arc-shaped groove 14, limiting the rotation range of the mounting base 110. In this embodiment, controlling the inward and outward rotation angle range of the mounting base 110 controls the inward and outward rotation angle range of the plate 3. The inward and outward rotation angle of the plate 3 is approximately 90 degrees, which allows the plate 3 to be fully opened or closed.

[0067] In actual use, in this embodiment of the children's high chair, when the tray 3 is installed on the first armrest 11 and the second armrest 12, the first retainer 301 and the second retainer 302 respectively engage in the slots 120 of the first armrest 11 and the second armrest 12, and the limiting member 34 protrudes from the side of the second armrest 12, limiting the tray 3 and ensuring that the tray 3 will not fall off the chair frame 1 during use, thus ensuring good structural stability. When it is necessary to rotate the tray 3 inward or outward, the limiting member 34 is driven to release the limiting member, and the limiting member 34 will drive the second retainer 302 to disengage from the slot 120 on the second armrest 12. At this time, the first retainer 301 has not disengaged from the slot 120 of the first armrest 11, ensuring that the tray 3 is reliably fixed to the first armrest 11. Rotating the first armrest 11 inward or outward will drive the tray 3 to rotate inward or outward, making the operation simple.

[0068] To ensure the high chair remains compact when folded, in this embodiment, both the armrest body 111 of the first armrest 11 and the second armrest 12 can be folded onto the chair frame 1. Specifically, both the first armrest 11 and the second armrest 12 include an armrest body 111, and the first armrest 11 body also includes a mounting base 110. A locking block 15 is movably disposed on both the first armrest 11 and the second armrest 12. In normal use, the locking block 15 on the first armrest 11 locks the armrest body 111 onto the mounting base 110, ensuring that the armrest body 111 is in the unfolded state and will not fold. The locking block 15 on the second armrest 12 locks the armrest body 111 onto the chair frame 1, ensuring that the second armrest 12 is in the unfolded state. When the dining chair is not in use and needs to be folded, unlock the locking block 15 on the first armrest 11, and rotate the armrest body 111 of the first armrest 11 downwards to fold it onto the chair frame 1. Unlock the locking block 15 on the second armrest 12, and rotate the second armrest 12 downwards to fold it onto the chair frame 1.

[0069] like Figures 10-16 As shown, in this embodiment, both the first armrest 11 and the second armrest 12 are provided with slots 120, into which the first slot 301 and the second slot 302 can be inserted respectively. The plate 3 is equipped with a positioning mechanism 30 and a limiting member 34. The positioning mechanism 30 ensures the stability of the plate 3 when it is fixed to the first armrest 11 and the second armrest 12, preventing the plate 3 from detaching from them. The limiting member 34 works in conjunction with the positioning mechanism 30 to limit the plate 3, preventing it from shaking during use.

[0070] Specifically, the card-positioning mechanism 30 includes a first card seat 301, a second card seat 302, and an unlocking control 303. The first card seat 301, the second card seat 302, the limiting member 34, and the unlocking control 303 are all movably disposed on the plate 3. The first card seat 301 and the second card seat 302 are symmetrically disposed on the plate 3 and can extend and retract. One end of the limiting member 34 is hinged to the plate 3, and a tension spring is disposed on the limiting member 34 away from its hinge end. One end of the tension spring abuts against the plate 3, and the other end abuts against the limiting member 34. When the limiting member 34 is not pressed, under the action of the tension spring, the limiting member 34 protrudes outward from the plate 3 to limit the plate 3. During use, when the plate 3 is mounted on the first armrest 11 and the second armrest 12, the first retainer 301 and the second retainer 302 respectively engage in the retaining grooves 120 of the first armrest 11 and the second armrest 12, ensuring that the plate 3 is securely fixed. The limiting member 34 protrudes from the side of the second armrest 12, preventing the plate 3 from detaching from the side of the second armrest 12. When the limiting member 34 is pressed down, it changes from an outwardly convex state to an inwardly concave state, no longer limiting the plate 3, allowing the plate 3 to be easily rotated outwards.

[0071] The unlocking control 303 can drive the first card holder 301 and the second card holder 302 to disengage from the card slot 120 on the first handrail 11 and the card slot 120 on the second handrail 12, respectively, and the limiting member 34 can drive the second card holder 302 to disengage from the card slot 120 on the second handrail 12. Specifically, the unlocking control 303 is configured as an unlocking handle. Each end of the unlocking handle has a drive link, and each drive link has a cylindrical protrusion. The first card holder 301 and the second card holder 302 are each provided with a triangular through groove. The two cylindrical protrusions 110A are respectively inserted into the two triangular through grooves. When the unlocking handle (i.e. the unlocking control 303) is pushed inward, the unlocking handle pushes against the first card holder 301 and the second card holder 302 through the two cylindrical protrusions 110A. The first card holder 301 and the second card holder 302 retract inward, so that the first card holder 301 and the second card holder 302 disengage from the slots 120 on the first armrest 11 and the second armrest 12, so that the first card holder 301 and the second card holder 302 are unlocked from the first armrest 11 and the second armrest 12. After unlocking, the plate 3 can be pushed and pulled back and forth.

[0072] Both the first card holder 301 and the second card holder 302 include an upper limit plate and a claw extending downward from the upper limit plate. The claw is adapted to the card slot 120. When the first card holder 301 and the second card holder 302 are respectively engaged in the card slots 120 on the first handrail 11 and the second handrail 12, the upper limit plate is above the first handrail 11 and the second handrail 12, and the claw is engaged in the card slot 120, ensuring stable engagement. The first card holder 301, the second card holder 302, and the unlocking handle are all equipped with return springs. When the unlocking handle is released without being pushed, the return springs can drive the unlocking handle to reset. The return springs on the first card holder 301 and the second card holder 302 can respectively drive the first card holder 301 and the second card holder 302 to reset, facilitating engagement in the card slot 120.

[0073] The first armrest 11 and the second armrest 12 are provided with multiple slots 120 along their length. The first bracket 301 and the second bracket 302 can be engaged in the slots 120 at different positions, so that the plate 3 is held at different positions on the first armrest 11 and the second armrest 12. That is, as long as it is within the travel range of the plate 3's extension and retraction adjustment, the first bracket 301 and the second bracket 302 can be engaged in the slots 120 at the corresponding positions on the first armrest 11 and the second armrest 12, ensuring the structural stability of the plate 3 during use, and the plate 3 will not detach from the first armrest 11 and the second armrest 12.

[0074] In actual use, the first armrest 11 and the second armrest 12 of this embodiment are provided with multiple slots 120. When the unlocking control 303 is driven, the first slot 301 and the second slot 302 are disengaged from the slots 120 on the first armrest 11 and the second armrest 12, respectively, and the plate 3 can be pulled back and forth for adjustment. After the adjustment is completed, the first slot 301 and the second slot 302 are respectively locked into the slots 120 on the first armrest 11 and the second armrest 12, ensuring that the plate 3 can be kept at different positions on the first armrest 11 and the second armrest 12.

[0075] It needs to be explained that the bottom surface of the plate 3 has a roughly U-shaped protrusion and a roughly L-shaped protrusion. When the plate 3 is installed on the first armrest 11 and the second armrest 12, the first armrest 11 is inserted into the U-shaped protrusion and will not detach from it. The second armrest 12 is inserted into the L-shaped protrusion. To prevent the second armrest 12 from detaching from the L-shaped protrusion, a limiting member 34 is provided. In the embodiment, the limiting member 34 is configured as a limiting button. Under normal use, the limiting member 34 protrudes from the bottom surface of the plate 3 and can abut against the side wall of the second armrest 12 to prevent the plate 3 from detaching from the second armrest 12. When it is necessary to rotate the plate 3 outward, the limiting member 34 is first pressed down and recessed into the plate 3 and no longer protrudes outward. The limiting member 34 will no longer limit the plate 3. When the plate 3 rotates outward, the L-shaped protrusion will not interfere with the second handrail 12, ensuring that the plate 3 can rotate outward normally.

[0076] On the side of the second card holder 302 near the limiting member 34, a protrusion extends out. When the second card holder 302 is inserted into the slot 120 on the second armrest 12, the protrusion is above the limiting member 34, and the protrusion is opposite to the limiting member 34 through an inclined wall. When the limiting member 34 is pressed, the limiting member 34 squeezes the inclined wall on the protrusion, causing the second card holder 302 to retract inward and disengage from the slot 120 of the second armrest 12. The second card holder 302 can be unlocked by pressing the limiting member 34, making it easy for the plate 3 to detach from the second armrest 12. At this time, the first card holder 301 is not unlocked. The first card holder 301 is still engaged in the slot 120 of the first armrest 11. Because when the plate 3 rotates outward, the first armrest 11 and the plate 3 are in a fixed connection state, and the first armrest 11 and the plate 3 do not move relative to each other. The plate 3 can rotate inward and outward with the inward and outward rotation of the first armrest 11. While the plate 3 rotates inside and outside, the second armrest 12 remains stationary.

[0077] As a preferred embodiment, an unlocking button 35 can be added to the side near the plate 3. The unlocking button 35 is used to release the limiting member 34 from its position. Specifically, by pressing the unlocking button 35, the limiting member 34 retracts inward into the plate 3, thus removing its constraint on the plate 3. This solution adds a dedicated unlocking button 35 to release the limiting member 34 from its position on the plate 3. If the position of the limiting member 34 itself is inconvenient to press for unlocking, this embodiment provides the unlocking button 35 for convenient release of the limiting position.

[0078] Of course, it is also possible to eliminate the need for an additional unlock button 35. The limiter 34 can be pressed directly to retract and release the restriction on the plate 3, thus achieving the same solution. The unlock button 35 can be selected based on the user's needs.

[0079] Preferably, the plate 3 in this embodiment includes a top cover 31, an upper shell 32, and a lower shell 33. The upper shell 32 and the lower shell 33 together form an installation cavity. A locking mechanism 30 is installed in the installation cavity. The top cover 31 is detachably mounted on the upper shell 32. Specifically, an elastic buckle extends downward from each side of the top cover 31. When the top cover 31 is mounted on the upper shell 32, the two elastic buckles engage with the upper shell 32 or the lower shell 33, ensuring that the top cover 31 will not detach. When it is necessary to remove the top cover 31, the two elastic buckles are manually released from the upper shell 32 or the lower shell 33, and the top cover 31 can be removed. During use, children can eat or play with toys on the top cover 31. When the plate 3 gets dirty, the top cover 31 can be directly removed from the upper shell 32 for cleaning, without having to remove the entire plate 3 for cleaning, making cleaning convenient.

[0080] like Figure 17 As shown, in this embodiment of the children's high chair, the chair frame 1 includes a backrest 16, which can be tilted to ensure the comfort of the child. Specifically, a handle 17 is movably installed on the backrest 16, and the handle 17 is connected to two locking pins 170. Multiple locking holes 180 are provided on the main body of the chair frame 1. When it is necessary to adjust the tilt of the backrest 16, the handle 17 can be pulled first, causing the two locking pins 170 to disengage from the locking holes 180 on the left and right sides respectively, unlocking the backrest 16, and then the tilt of the backrest 16 can be adjusted. After adjustment, the two locking pins 170 respectively engage with the locking holes 180, keeping the backrest 16 in the adjusted position. Adjusting the tilt of the backrest 16 can change the child's sitting posture, improve the child's comfort, and can be used in different scenarios.

[0081] like Figure 18As shown, the chair frame 1 of the children's high chair is also equipped with a movable leg rest 40 on the front side, which can support the child's legs. Specifically, the movable leg rest 40 is fixed to the chair frame 1 by two locking gears 41. One side of the teeth of the locking gears 41 is provided with a bevel, forming a ratchet-like structure. When adjusting the leg rest 40 upward, the leg rest 40 can be rotated directly upward. When it is necessary to adjust the leg rest 40 downward, the unlocking button 42 needs to be pressed to unlock the locking gears 41 so that the leg rest 40 can be rotated downward.

[0082] Combination Figures 3-6 As shown, the working principle of the children's high chair in this embodiment is as follows:

[0083] When the tray 3 is not installed on the first armrest 11 and the second armrest 12, the locking member 21 locks into the locking groove 10 on the chair frame 1, restricting the first armrest 11 from rotating inward and outward.

[0084] When the child's high chair is needed, align the U-shaped and L-shaped protrusions on the tray 3 with the first armrest 11 and the second armrest 12 respectively, so that the first seat 301 is inserted into the slot 120 on the first armrest 11 and the second seat 302 is inserted into the slot 120 on the second armrest 12. During this process, the guide strip 330 on the U-shaped protrusion is aligned with the guide groove 111B on the first armrest 11 and slides into the guide groove 111B. At this time, the guide strip 330 pushes the unlocking member 23 inward, the unlocking member 23 retracts, and drives the slide 22 to move forward. The slide 22 pulls the locking member 21 through the cable 24, so that the locking member 21 is disengaged from the locking groove 10, and the locking member 21 no longer restricts the inward and outward rotation of the first armrest 11. In this state, in addition to the first card holder 301 being inserted into the card slot 120 on the first armrest 11 and the second card holder 302 being inserted into the card slot 120 on the second armrest 12, the limiting member 34 is also in an outward protruding state, forming a limit to prevent the plate 3 from detaching from the second armrest 12.

[0085] When the tray 3 needs to be rotated outward from the chair frame 1, the limiting member 34 is pressed down, and the limiting member 34 changes from an outward protruding state to no longer protruding on the side of the second armrest 12. The limiting member 34 no longer limits the second armrest 12. During the process of the limiting member 34 being pressed down, the limiting member 34 drives the second seat 302 to disengage from the slot 120 of the second armrest 12. The tray 3 is no longer fixedly connected to the second armrest 12, and at this time the locking member 21 is also in the state of disengaging from the locking slot 10. The inward and outward rotation freedom of the first armrest 11 is not restricted, so the tray 3 can be rotated outward to disengage from the second armrest 12. Both the tray 3 and the first armrest 11 rotate outward around the vertical rotation center, i.e., the central axis 13. The tray 3 rotates away from the opening 100, making it convenient for children to get in and out of the high chair.

[0086] When the high chair is in normal use, the tray 3 is installed on the first armrest 11 and the second armrest 12. When it is necessary to adjust the tray 3 by pulling it out, pushing the unlocking control 303 inward unlocks the handle. The unlocking control 303 causes the first retaining seat 301 and the second retaining seat 302 to retract inward, disengaging from the retaining slots 120 on the first armrest 11 and the second armrest 12, respectively. This allows the tray 3 to be pulled out and adjusted. After releasing the unlocking control 303, the first retaining seat 301 and the second retaining seat 302 re-engage into the retaining slots 120 on the first armrest 11 and the second armrest 12, respectively, keeping the tray 3 in the adjusted position.

[0087] When it is necessary to remove the plate 3 from the first armrest 11 and the second armrest 12, it is also necessary to push the unlocking control 303 inward so that the first card holder 301 and the second card holder 302 disengage from the card slot 120 of the first armrest 11 and the card slot 120 of the second armrest 12 respectively. Pull the plate 3 forward to disengage it from the first armrest 11 and the second armrest 12 and remove the plate 3.

[0088] When the tray 3 is removed from the first armrest 11 and the second armrest 12, and the chair frame 1 needs to be folded, push the locking block 15 on the armrest body 111 of the first armrest 11 outward to unlock the armrest body 111 from the mounting base 110, so that the armrest body 111 of the first armrest 11 can be rotated downward and folded onto the chair frame 1; push the locking block 15 on the second armrest 12 outward to unlock the second armrest 12 from the chair frame 1, so that the second armrest 12 can be rotated downward and folded onto the chair frame 1, reducing the space occupied by the chair frame 1.

[0089] In this solution, the structure for rotating the tray of the children's high chair is simple, the overall structure of the children's high chair is simple, the structure of the tray 3 is simple, and the rotation of the tray 3 is convenient.
