[0019] Further, the first armrest includes a mounting seat arranged at one end thereof, the mounting seat is rotatably arranged on the chair frame, and its rotation center is the vertical rotation center;

[0020] The chair frame is provided with a locking groove, and when the locking member is locked into the locking groove, the locking member restricts the mounting seat from rotating.

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

[0022] The protrusion limits the rotation range of the mounting seat by abutting against two ends of the arc-shaped groove.

[0023] Furthermore, the first armrest and the second armrest are both provided with a card slot;

[0024] The dinner tray is provided with a locking mechanism and a limiting member, the locking mechanism comprises a first locking seat, a second locking seat and an unlocking control member, the first locking seat, the second locking seat, the limiting member and the unlocking control member are all movably arranged on the dinner tray, when the dinner tray is mounted on the first armrest and the second armrest, the first locking seat and the second locking seat are respectively locked in the locking grooves of the first armrest and the second armrest, and the limiting member protrudes from the side of the second armrest to limit the dinner tray from detaching from the side of the second armrest; the unlocking control member can drive the first locking seat and the second locking seat to detach from the locking grooves respectively, and the limiting member can drive the second locking seat to detach from the locking grooves on the second armrest.

[0025] Furthermore, the first armrest and the second armrest are each provided with a plurality of slots along their length direction; the first card holder and the second card holder can be inserted into the card slots at different positions, so that the dining tray is kept at different positions on the first armrest and the second armrest;

[0026] When the limiting member limiting the position of the dining tray is released, the limiting member drives the second card seat to disengage from the card slot on the second armrest, and the dining tray rotates along with the inward and outward rotation of the first armrest.

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

[0028] In the present invention, when the dining tray is not installed, the locking member in the locking mechanism is locked to the chair frame, limiting the inward and outward rotation of the first armrest; when the dining tray is installed on the first armrest, the dining tray unlocks the locking member, releasing the inward and outward rotation limit of the first armrest. When the first armrest is rotated inward and outward, the first armrest can drive the dining tray to rotate inward and outward accordingly, thereby controlling the opening and closing of the opening on the chair frame, rather than the dining tray itself rotating relative to the first armrest. The structure for realizing the rotation of the dining tray is simple, which can simplify the structure of the dining chair, and the overall structure of the dining tray is also simpler.

[0029] In the present invention, when the dining tray is mounted on the first armrest and the second armrest, the first holder and the second holder are respectively engaged in the slots of the first armrest and the second armrest, and the limiting member protrudes from the side of the second armrest to limit the dining tray, thereby ensuring that the dining tray will not fall off the chair frame during use, and the structural stability is good. When the dining tray needs to be rotated inward and outward, the limiting member is driven to release the limit, and the limiting member will drive the second holder to disengage from the slot on the second armrest, while the first holder at this time does not disengage from the slot of the first armrest, thereby ensuring that the dining tray and the first armrest are reliably fixed, and the first armrest can drive the dining tray to rotate inward and outward by rotating inward and outward, and the operation is simple.

[0030] In the present invention, a plurality of card slots are provided on the first armrest and the second armrest. When the unlocking control component is driven to disengage the first card seat and the second card seat from the card slots on the first armrest and the second armrest respectively, the dining plate can be adjusted by pulling it forward and backward. When the adjustment is completed, the first card seat and the second card seat are respectively inserted into the card slots of the first armrest and the second armrest, so as to ensure that the dining plate can be kept at different positions of the first armrest and the second armrest.

[0054] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0055] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0056] In addition, in the present invention, descriptions such as "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0057] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0059] Combination Figure 1-Figure 3 as well as Figure 9-10As shown, the children's dining chair of this embodiment mainly includes: a chair frame 1 and a dining tray 3. The first armrest 11 of the chair frame 1 is provided with a locking mechanism 2, and the dining tray 3 is provided with a locking mechanism 30 and a stopper 34. Among them, the chair frame 1 is provided with an opening 100 for children to enter and exit. The opening 100 is located at the front side of the chair frame 1. Adults can put children into the children's dining chair through the opening 100, and can also take children out of the children's dining chair through the opening 100. The first armrest 11 and the second armrest 12 are respectively provided on both sides of the chair frame 1 near the opening 100. In the drawings of this embodiment, it is shown that the second armrest 12 is on the left side of the chair frame 1 and the first armrest 11 is 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 the vertical rotation center. Specifically, the first armrest 11 is hinged to the chair frame 1 through a central axis 13, and the central axis 13 is configured as the vertical rotation center. The locking mechanism 2 is arranged on the first armrest 11, and includes a locking member 21, which can be a locking pin. The locking member 21 can be locked to the chair frame 1 to limit the first armrest 11 from rotating inward and outward. The dining tray 3 is detachably arranged on the first armrest 11 and the second armrest 12. When the dining tray 3 is installed on the first armrest 11, the dining tray 3 unlocks the locking member 21, so that the locking member 21 releases the limit of the first armrest 11 from rotating inward and outward; and the first armrest 11 rotates inward and outward to drive the dining tray 3 to rotate inward and outward at the opening 100. That is, when the dining tray 3 is not installed, the first armrest 11 is in a state of being limited by the locking member 21 and cannot rotate inward and outward. After the dining tray 3 is installed on the first armrest 11, the locking member 21 is forced to release the limit of the first armrest 11 from rotating inward and outward. When the first armrest 11 rotates inward and outward, the dining tray 3 can rotate inward and outward along with the first armrest 11 rotating inward and outward.

[0060] When a child needs to get in or out of the child dining chair, the first armrest 11 can be rotated outward to drive the dining tray 3 to rotate outward and open, that is, the dining tray 3 is opened outward from the opening 100, so that the child can get in or out of the child dining chair conveniently. When the child dining chair is used normally, the dining tray 3 is mounted and fixed on the first armrest 11 and the second armrest 12, the dining tray 3 blocks the opening 100, and the child can eat on the dining tray 3.

[0061] In this embodiment, when the dining tray 3 is not installed, the locking member 21 in the locking mechanism 2 is locked to the chair frame 1, limiting the first armrest 11 from rotating inward and outward, thereby ensuring the normal use function of the armrest. When the dining tray 3 is installed on the first armrest 11, the dining tray 3 unlocks the locking member 21, releasing the inward and outward rotation limit of the first armrest 11, so that the dining tray 3 can 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 dining tray 3 to rotate inward and outward accordingly, thereby controlling the opening and closing of the opening 100 on the chair frame 1. In the existing structure, when the dining tray 3 rotates inward and outward, it rotates inward and outward relative to the armrest, and its implementation structure is complex, with many parts, and the structure of the dining tray 3 is also relatively complex. In this embodiment, the first armrest 11 rotates inward and outward to drive the dining tray 3 to rotate inward and outward, rather than the dining tray 3 itself rotating inward and outward relative to the first armrest 11. In this embodiment, the implementation structure of the rotation of the dining tray 3 is simple, that is, the structure of the dining chair can be simplified, and the overall structure of the dining tray 3 is simpler.

[0062] like Figure 7-10 As shown, the locking mechanism 2 of this embodiment includes an unlocking module, which is movably arranged on the first armrest 11. When the dining tray 3 is mounted on the first armrest 11, the dining tray 3 pushes the unlocking module to unlock the locking member 21. The unlocking module is connected to the locking member 21. When the dining tray 3 is mounted on the first armrest 11, the dining tray 3 pushes the unlocking module, thereby driving the locking member 21, so that the locking member 21 is unlocked from the chair frame 1, and the first armrest 11 is no longer restricted from rotating inward and outward.

[0063] As a preferred embodiment, the unlocking module of this embodiment includes a slide 22 and an unlocking member 23. The slide 22 is slidably arranged in the first armrest 11, specifically, the slide 22 can slide along the length direction of the first armrest 11, and the slide 22 is connected to the locking member 21 by a cable 24. The unlocking member 23 is arranged on the slide 22, and the unlocking member 23 can drive the slide 22 to slide. Specifically, the slide 22 is provided with an inclined groove 220 inclined relative to its sliding direction, and the unlocking member 23 is provided with a protrusion 230, and the protrusion 230 extends into the inclined groove 220. A mounting groove 111A is provided on the side of the first armrest 11, and the unlocking member 23 is telescopically arranged in the mounting groove 111A, and the telescopic movement direction of the unlocking member 23 is perpendicular to the sliding direction of the slide 22, that is, the telescopic movement direction of the unlocking member 23 is perpendicular to the length direction of the first armrest 11, and the unlocking module changes the power transmission direction. When the dining tray 3 is mounted on the first armrest 11, the dining tray 3 drives 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 to unlock the locking member 21 from the chair frame 1. The unlocking member 23 and the locking member 21 are both provided with reset springs, which can respectively ensure that the unlocking member 23 and the locking member 21 can be reset in time.

[0064] Of course, the unlocking module can also be implemented in other ways, for example: the slide seat 22 and the unlocking piece 23 are made into an integral component. When the dining tray 3 is installed on the first armrest 11, inclined surfaces are provided on the dining tray 3 and the unlocking module. The inclined surfaces squeeze each other, and the dining tray 3 squeezes the integrated unlocking module, so that the unlocking module moves forward along the length direction of the first armrest 11, pulling the locking piece 21 to unlock the locking piece 21 from the chair frame 1.

[0065] Specifically, in this embodiment, the unlocking member 23 at least partially extends from the first armrest 11, so that when the dining tray 3 is installed on the first armrest 11, it is convenient for the dining tray 3 to push the unlocking member 23. In addition, if the dining tray 3 is not installed, the user can press the protruding part of the unlocking member 23 by hand or other tools, and the locking member 21 can also be finally unlocked by the unlocking member 23, which is convenient to use. More specifically, the first armrest 11 is provided with a guide groove 111B along its length direction, and the guide groove 111B is a long groove opened on the side of the first armrest 11, and the unlocking member 23 at least partially protrudes from the guide groove 111B. A guide slide convex strip 330 is provided on the dining tray 3. When the dining tray 3 is mounted on the first armrest 11, the guide slide convex strip 330 penetrates into the guide slide groove 111B from the end of the armrest, and the guide slide convex strip 330 pushes the unlocking member 23, so that the unlocking member 23 retracts and moves. The unlocking member 23 drives the slide seat 22 to move forward, and the slide seat 22 pulls the locking member 21 through the cable 24, so that the locking member 21 is unlocked. The cross-sections of the guide slide groove 111B and the guide slide convex strip 330 are preferably rectangular. The cooperation between the guide slide groove 111B and the guide slide convex strip 330 can also play a guiding role when the dining tray 3 is telescopically adjusted, and can also ensure that the dining tray 3 does not shake up and down during the rotation process.

[0066] In this embodiment, the first armrest 11 includes a mounting seat 110 disposed at one end thereof, and also includes an armrest body 111. The mounting seat 110 is rotatably disposed on the chair frame 1, and its rotation center is the vertical rotation center, that is, the mounting seat 110 is disposed on the chair frame 1 so as to be rotatable inward and outward relative to the vertical rotation center (central axis 13). The mounting seat 110 rotates inward and outward, so that the first armrest 11 rotates 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 seat 110. When the locking member 21 is unlocked, the locking member 21 escapes from the locking groove 10. In addition, an arc groove 14 is provided on the chair frame 1 along the circumference of the vertical rotation center. The arc groove 14 is opened with the vertical rotation center as the center. The mounting seat 110 has a protrusion 110A, and the protrusion 110A extends into the arc groove 14. The protrusion 110A limits the rotation range of the mounting seat 110 by abutting against the two ends of the arc groove 14. In this embodiment, by controlling the inner and outer rotation angle range of the mounting seat 110, the inner and outer rotation angle range of the dining tray 3 can be controlled. The inner and outer rotation angle of the dining tray 3 is approximately 90 degrees, which can control the dining tray 3 to be fully opened or folded.

[0067] In actual use, when the dining tray 3 is mounted on the first armrest 11 and the second armrest 12, the first holder 301 and the second holder 302 are respectively engaged 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 to limit the dining tray 3, thereby ensuring that the dining tray 3 does not fall off the chair frame 1 during use, and the structural stability is good. When the dining tray 3 needs to be rotated inward and outward, the limiting member 34 is driven to release the limit, and the limiting member 34 will drive the second holder 302 to disengage from the slot 120 on the second armrest 12, while the first holder 301 at this time does not disengage from the slot 120 of the first armrest 11, thereby ensuring that the dining tray 3 is reliably fixed to the first armrest 11, and the first armrest 11 can drive the dining tray 3 to rotate inward and outward by rotating inward and outward, and the operation is simple.

[0068] In order to ensure that the volume of the children's dining chair is compact after being folded, in this embodiment, the armrest body 111 of the first armrest 11 and the second armrest 12 can be folded onto the chair frame 1. Specifically, the first armrest 11 and the second armrest 12 both include an armrest body 111, and the first armrest 11 body also includes a mounting seat 110, wherein a locking block 15 is movably provided on the first armrest 11 and the second armrest 12. In a normal use state, the locking block 15 on the first armrest 11 locks the armrest body 111 of the first armrest 11 on the mounting seat 110, ensuring that the armrest body 111 of the first armrest 11 is in an unfolded state and will not be folded. The locking block 15 on the second armrest 12 locks the armrest body 111 of the second armrest 12 on the chair frame 1, ensuring that the second armrest 12 is in an unfolded state. When the dining chair is not in use and needs to be folded, the locking block 15 on the first armrest 11 is unlocked, and the armrest body 111 of the first armrest 11 is rotated downward and folded onto the chair frame 1. The locking block 15 on the second armrest 12 is unlocked, and the second armrest 12 is rotated downward and folded onto the chair frame 1.

[0069] like Figure 10-Figure 16 As shown, in this embodiment, the first armrest 11 and the second armrest 12 are both provided with a slot 120, which can be respectively inserted into the first and second holders 301 and 302. The dinner tray 3 is provided with a locking mechanism 30 and a limiting member 34. The locking mechanism 30 can ensure the stability of the dinner tray 3 when it is mounted and fixed on the first and second armrests 11 and 12, and the dinner tray 3 will not be separated from the first and second armrests 11 and 12. The limiting member 34 cooperates with the locking mechanism 30 to limit the dinner tray 3, and the dinner tray 3 is placed so as not to shake when in use.

[0070] Specifically, the locking mechanism 30 includes a first locking seat 301, a second locking seat 302 and an unlocking control member 303. The first locking seat 301, the second locking seat 302, the limiting member 34 and the unlocking control member 303 are all movably arranged on the dinner plate 3. The first locking seat 301 and the second locking seat 302 are symmetrically arranged on the dinner plate 3 and can move telescopically. One end of the limiting member 34 is hinged to the dinner plate 3, and a tensioning spring is arranged on the limiting member 34 away from its hinged end. One end of the tensioning spring abuts against the dinner 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 tensioning spring, the limiting member 34 protrudes outward from the dinner plate 3 so as to limit the dinner plate 3. During use, after the dining tray 3 is mounted on the first armrest 11 and the second armrest 12, the first clamping seat 301 and the second clamping seat 302 are respectively clamped in the clamping slots 120 of the first armrest 11 and the second armrest 12, ensuring that the dining tray 3 is reliably fixed, and the limiting member 34 protrudes from the side of the second armrest 12, limiting the dining tray 3 from being separated from the side of the second armrest 12. When the limiting member 34 is pressed, it changes from a convex state to a concave state, and no longer limits the dining tray 3, so that the dining tray 3 can be conveniently rotated outward.

[0071] The unlocking control member 303 can drive the first card holder 301 and the second card holder 302 to disengage from the card slot 120 on the first armrest 11 and the card slot 120 on the second armrest 12 respectively, and the limiting member 34 can drive the second card holder 302 to disengage from the card slot 120 on the second armrest 12. Specifically, the unlocking control member 303 is configured as an unlocking handle, and the two ends of the unlocking handle are respectively provided with a driving connecting rod, and a cylindrical convex portion protrudes from the driving connecting rod. A triangular through groove is provided on the first card seat 301 and the second card seat 302, and two cylindrical protrusions 110A are respectively inserted into the two triangular through grooves. When the unlocking handle (i.e., the unlocking control member 303) is pushed inward, the unlocking handle pushes the first card seat 301 and the second card seat 302 respectively through the two cylindrical protrusions 110A, and the first card seat 301 and the second card seat 302 both retract inward, so that the first card seat 301 and the second card seat 302 are disengaged from the card slot 120 on the first armrest 11 and the card slot 120 on the second armrest 12, so that the first card seat 301 and the second card seat 302 are unlocked from the first armrest 11 and the second armrest 12, and the dining tray 3 can be pushed and pulled forward and backward after unlocking.

[0072] The first card holder 301 and the second card holder 302 each include an upper limit plate and a claw extending downward from the upper limit plate, and the claw is adapted to the card slot 120. When the first card holder 301 and the second card holder 302 are respectively clamped in the card slot 120 on the first armrest 11 and the second armrest 12, the upper limit plate is above the first armrest 11 and the second armrest 12, and the claw is clamped in the card slot 120 to ensure stable clamping. A reset spring is provided on the first card holder 301, the second card holder 302 and the unlocking handle. When the unlocking handle is no longer pushed and released, the reset spring thereon can drive the unlocking handle to reset. The reset 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, so as to facilitate the clamping in the card slot 120.

[0073] The first armrest 11 and the second armrest 12 are both provided with a plurality of slots 120 along their length direction; the first slot holder 301 and the second slot holder 302 can be inserted into the slots 120 at different positions, so that the dining tray 3 is kept at different positions on the first armrest 11 and the second armrest 12. That is, as long as the dining tray 3 is within the travel range of telescopic adjustment, the first slot holder 301 and the second slot holder 302 can be inserted into the slots 120 at corresponding positions of the first armrest 11 and the second armrest 12, respectively, to ensure the structural stability of the dining tray 3 when in use, and the dining tray 3 will not be separated from the first armrest 11 and the second armrest 12.

[0074] In actual use, in this embodiment, a plurality of slots 120 are provided on the first armrest 11 and the second armrest 12. When the unlocking control member 303 is driven to disengage the first card holder 301 and the second card holder 302 from the slots 120 on the first armrest 11 and the second armrest 12 respectively, the dining tray 3 can be adjusted by pulling it forward and backward. When the adjustment is completed, the first card holder 301 and the second card holder 302 are respectively inserted into the slots 120 of the first armrest 11 and the second armrest 12 to ensure that the dining tray 3 can be maintained at different positions of the first armrest 11 and the second armrest 12.

[0075] It needs to be explained that the bottom surface of the dining tray 3 is provided with a roughly U-shaped protrusion and a roughly L-shaped protrusion. When the dining tray 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 the first armrest 11 will not be separated from the U-shaped protrusion. The second armrest 12 is inserted into the L-shaped protrusion. In order to prevent the second armrest 12 from being separated from the L-shaped protrusion, a limiting member 34 is provided. The limiting member 34 of the embodiment is configured as a limiting button. Under normal use, the limiting member 34 protrudes outward from the bottom surface of the dining tray 3 and can be abutted against the side wall of the second armrest 12 to prevent the dining tray 3 from being separated from the second armrest 12. When the dining tray 3 needs to be rotated outward, the limiting member 34 is first pressed down, and the recessed dining tray 3 no longer protrudes outward, and the limiting member 34 will no longer form a limiting effect on the dining tray 3. When the dining tray 3 rotates outward, the L-shaped outer protrusion will not interfere with the second armrest 12, thereby ensuring that the dining tray 3 can rotate outward normally.

[0076] A protrusion extends from one side of the second holder 302 close to the stopper 34. When the second holder 302 is inserted into the slot 120 on the second armrest 12, the protrusion is located above the stopper 34 and is opposite to the stopper 34 through an inclined wall. When the stopper 34 is pressed, the stopper 34 squeezes the inclined wall on the protrusion, causing the second holder 302 to retract and disengage from the slot 120 of the second armrest 12. The second holder 302 can be unlocked by pressing the stopper 34, which facilitates the separation of the dining tray 3 from the second armrest 12. At this time, the first holder 301 is not unlocked and is still engaged with the slot 120 of the first armrest 11. Because when the dining tray 3 rotates outward, the first armrest 11 and the dining tray 3 are in a fixed connection state, and the first armrest 11 and the dining tray 3 do not move relative to each other. The dining tray 3 can rotate inward and outward with the inward and outward rotation of the first armrest 11. While the dining tray 3 is rotating inward and outward, the second armrest 12 is in a stationary state.

[0077] As a preferred embodiment, an unlocking button 35 can be added at the side position close to the dining tray 3. The unlocking button 35 is used to release the limit of the limit member 34. That is, by pressing the unlocking button 35, the unlocking button 35 drives the limit member 34 to retract into the dining tray 3, so that the limit member 34 no longer limits the dining tray 3. This solution is to add a dedicated unlocking button 35 to release the limit of the dining tray 3 by the limit member 34. If the position of the limit member 34 itself is not convenient for pressing to unlock, the unlocking button 35 is configured in this embodiment to facilitate the release of the limit operation.

[0078] Of course, there is no need to add an additional unlocking button 35. The solution can be implemented by directly pressing the limiting member 34 to retract the limiting member 34 and release the limit on the dining plate 3. The unlocking button 35 can be selected according to the needs of the user.

[0079] Preferably, the dinner plate 3 of this embodiment comprises a top cover 31, an upper shell 32 and a lower shell 33, the upper shell 32 and the lower shell 33 enclose an installation cavity, the locking mechanism 30 is installed in the installation cavity, the top cover 31 is detachably arranged on the upper shell 32, specifically, both sides of the top cover 31 extend downwardly from an elastic buckle, when the top cover 31 is installed on the upper shell 32, the two elastic buckles are engaged with the upper shell 32 or the lower shell 33, ensuring that the top cover 31 will not be separated, when the top cover 31 needs to be removed, the two elastic buckles are manually buckled to separate the elastic buckles 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, and when the dinner plate 3 is dirty, the top cover 31 can be directly removed from the upper shell 32 to clean the top cover 31, without removing the entire dinner plate 3 for cleaning, which is convenient for cleaning.

[0080] like Fig.17 As shown, in the children's dining chair of this embodiment, the chair frame 1 includes a backrest 16, and the backrest 16 can be adjusted in inclination to ensure the comfort of the child. Specifically, a handle 17 is movably provided on the backrest 16, and the handle 17 is connected to two bayonet pins 170. A plurality of lock holes 180 are provided on the main body of the chair frame 1. When the inclination of the backrest 16 needs to be adjusted, the handle 17 can be pulled first, so that the two bayonet pins 170 are respectively disengaged from the lock holes 180 on the left and right sides, and the backrest 16 is unlocked, and then the inclination of the backrest 16 is adjusted. After the adjustment is completed, the two bayonet pins 170 are correspondingly inserted into the lock holes 180, so that the backrest 16 remains in the position after the adjustment. Adjusting the inclination of the backrest 16 can change the sitting posture of the child, improve the comfort of the child, and can be used in different scenarios.

[0081] like Fig.18As shown, a movable leg rest 40 is also provided on the front side of the chair frame 1 of the children's dining chair, and the movable leg rest 40 can be used to support the legs of the child. Specifically, the movable leg rest 40 is fixed to the chair frame 1 through two locking gears 41, and a bevel is provided on one side of the gear teeth of the locking gear 41 to form a ratchet-like structure. When the leg rest 40 is adjusted upward, the leg rest 40 can be directly rotated upward. When the leg rest 40 needs to be adjusted downward, the unlocking button 42 needs to be pressed to unlock the locking gear 41 so that the leg rest 40 can be rotated downward.

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

[0083] When the dining tray 3 is not mounted on the first armrest 11 and the second armrest 12 , the locking member 21 is locked into the locking slot 10 on the chair frame 1 , thereby restricting the first armrest 11 from rotating inwards and outwards.

[0084] When the children's dining chair needs to be used, the U-shaped outer protrusion and the L-shaped outer protrusion on the dining tray 3 are aligned with the first armrest 11 and the second armrest 12 respectively, so that the first holder 301 is inserted into the slot 120 on the first armrest 11, and the second holder 302 is inserted into the slot 120 on the second armrest 12. During this process, the guide slide convex strip 330 on the U-shaped outer protrusion is aligned with the guide slide groove 111B on the first armrest 11 and slides into the guide slide groove 111B. At this time, the guide slide convex strip 330 pushes the unlocking piece 23 inward, and the unlocking piece 23 retracts, driving the slide seat 22 to move forward. The slide seat 22 pulls the locking piece 21 through the cable 24, so that the locking piece 21 is disengaged from the locking slot 10, and the locking piece 21 no longer restricts the first armrest 11 from rotating inward and outward. In this state, in addition to the first holder 301 being inserted into the slot 120 on the first armrest 11 and the second holder 302 being inserted into the slot 120 on the second armrest 12 , the limiting member 34 is also in an outwardly convex state, forming a limit to prevent the dining tray 3 from detaching from the second armrest 12 .

[0085] When the dining tray 3 needs to be rotated outward from the chair frame 1, the limiting member 34 is pressed down, and the limiting member 34 switches from the convex state to no longer convex state on the side of the second armrest 12, and the limiting member 34 no longer forms a limit on the second armrest 12. In the process of pressing down the limiting member 34, the limiting member 34 drives the second holder 302 to disengage from the slot 120 of the second armrest 12, and the dining tray 3 is no longer fixedly connected to the second armrest 12, and the locking member 21 is also in a state of disengaging from the locking slot 10 at this time, and the first armrest 11 is not restricted in its inward and outward rotation freedom, so that the dining tray 3 can be rotated outward to disengage from the second armrest 12, and the dining tray 3 and the first armrest 11 are both rotated outward around the vertical rotation center, that is, the central axis 13, and the dining tray 3 is rotated away from the opening 100, so that children can enter and exit the dining chair conveniently.

[0086] The children's dining chair is in normal use, and the dining tray 3 is installed on the first armrest 11 and the second armrest 12. When the dining tray 3 needs to be pulled forward and backward, the unlocking control member 303 is pushed inward to unlock the handle, and the unlocking control member 303 drives the first clamping seat 301 and the second clamping seat 302 to retract, and respectively disengage from the clamping slot 120 on the first armrest 11 and the clamping slot 120 on the second armrest 12, so that the position of the dining tray 3 can be adjusted by pulling. After releasing the unlocking control member 303, the first clamping seat 301 and the second clamping seat 302 are respectively clamped into the clamping slot 120 on the first armrest 11 and the clamping slot 120 on the second armrest 12, so that the dining tray 3 is kept at the adjusted position.

[0087] When the dinner tray 3 needs to be removed from the first armrest 11 and the second armrest 12, it is also necessary to push the unlocking control part 303 inward to disengage the first card holder 301 and the second card holder 302 from the card slot 120 of the first armrest 11 and the card slot 120 of the second armrest 12 respectively, and pull the dinner tray 3 forward to disengage the dinner tray 3 from the first armrest 11 and the second armrest 12, and remove the dinner tray 3.

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

[0089] In this solution, the structure for implementing the rotation of the dining tray of the children's dining chair is simple, the overall structure of the children's dining chair is simple, the structure of the dining tray 3 is simple, and the dining tray 3 is easy to rotate.
