Referring to fig. 1 to 3, the present application provides a child dining chair, including a frame 100 and a seat 200 slidably mounted on the frame 100, wherein the frame 100 includes a first leg bar 110 having a plurality of locking grooves 111 along a length direction, the seat 200 is provided with a sliding sleeve 210 slidably engaged with the first leg bar 110, the sliding sleeve 210 is movably mounted with a locking pin 211 corresponding to the locking grooves 111, and the locking pin 211 has a locking state inserted into the locking grooves 111 and a releasing state withdrawn from the locking grooves 111. The support 100 may only include one leg (the first leg 110), or as shown in the drawings, the support 100 further includes a second leg 120 movably connected to the first leg 110. The extension of the locking groove 111 along the length of the first leg 110 is to be understood as the first leg 110 having a straight section on which the locking groove 111 is arranged; of course, the section of the locking groove 111 disposed on the first leg 110 may also be an arc-shaped section. The locking slot and the locking pin constitute a locking mechanism for maintaining the fixed state of the seat relative to the first leg bar 110.

The seat in this embodiment comprises a seat plate 220 for supporting the buttocks of the child, a backrest 230 for supporting the back of the child, and two side stoppers 240, wherein the two side stoppers 240 are connected to both sides of the seat plate 220 to prevent the child from falling and to be held by the child when the child sits on the seat plate, and the sliding sleeve 210 is fixedly installed on the side stoppers 240. The side keeps off inside being provided with can be along the gliding driving medium 250 that is used for driving locking pin 211 of first direction, and movable mounting has the unblock piece 260 of taking interference portion 261 on the driving medium 250, and unblock piece 260 has:

in the first position, the interference part 261 abuts against the side stop 240 to limit the sliding of the transmission member 250;

in the second position, the interference portion 261 clears the side stop 240, allowing the unlocking member 260 to slide along with the transmission member 250 in the first direction.

The unlocking member 260 may be mounted to rotate or slide relative to the transmission member 250, and is switched between the first position and the second position by corresponding movement. The driving member 250 can be understood as an unlocking element of the locking mechanism, and the unlocking member 260 and the side rail 240 constitute a two-way locking mechanism, which improves safety in use, and a part of the two-way locking mechanism is the side rail 240, reducing manufacturing costs. And the unlocking member 260 may be an extension of the driving member 250 when in the second position, facilitating the unlocking operation.

Referring to fig. 4 to 11, in an embodiment, the unlocking member 260 slides along a second direction, which is not the same direction as the first direction, and the driving member 250 is provided with a first elastic member 310 (e.g., a spring) acting on the unlocking member 260 at the first position. The unlocking member 260 has a button 262 protruding from the side stop 240, and a part of the button 262 protrudes radially to form an interference portion 261. The second direction is in the plane of radial place, and button 262 protrusion side fender 240 sets up, and on the one hand makes things convenient for the operator to discern, and on the other hand button 262 interference portion 261 protrudes in side fender 240 equally, and the outer peripheral face of trunk side fender 240 offsets in the figure in the bottom surface of interference portion 261, and side fender 240 need not to set up the step, and the outward appearance is succinct. The top of the button 262 is recessed to provide a groove 265 for placing a finger for driving, so as to facilitate force application.

In order to facilitate the unlocking element 260 to slide, the transmission element 250 is provided with a first sliding groove 251 extending along the second direction, the unlocking element 260 is provided with a first sliding block 263 matched with the first sliding groove 251, and the first elastic element 310 is arranged in the first sliding groove 251 and acts on the first sliding block 263. The first slider 263 has an i-shaped cross section, so that the unlocking member 260 slides more stably and smoothly.

In order to avoid the unlocking member 260 from sliding between the first position and the second position, and to prevent the other part of the button 262 from abutting against the side stop 240 due to the excessive sliding stroke, in an embodiment, the bottom of the button 262 is provided with a projection 264 that abuts against the first chute wall 253 in the second position, so as to limit the sliding stroke in the sliding process.

The side stop 240 is provided with a second sliding groove 241 engaged with the transmission member 250, the second sliding groove 241 is provided with a second elastic member 320 acting on the transmission member 250, the second sliding groove 241 is provided with an opening 242 allowing the button 262 to enter, and the second elastic member 320 is a spring, so that the button 262 can protrude out of the side stop 240 when the transmission member 250 is reset. The groove wall of the second sliding groove 241 is adapted to the transmission member 250 to play a role of sliding guide, in addition, the first sliding groove 251 has a notch 252 for the unlocking member 260 to be slidably installed, and the notch 252 is closed by the groove wall of the second sliding groove to prevent the unlocking member 260 from slipping out of the transmission member 250.

Referring to fig. 12 and 13, in an embodiment, the locking pin 211 is rotatably connected in the side rail 240, and the seat 200 includes a first link member 270, a second link member 280, and a third elastic member (not shown in an assembled state), wherein the first link member 270 is slidably disposed in the side rail 240, and is connected to the locking pin 211 to drive the locking pin 211 to rotate; the second linkage member 280 is rotatably disposed in the side stop 240, and the second linkage member 280 has a first end pivotally connected to the first linkage member 270, and a second end acted on by the transmission member 250; the third elastic member is a torsion spring, which is disposed in the side stopper 240 and acts to insert the locking pin 211 into the locking groove 111.

Referring now to fig. 10-13 in conjunction with the above embodiment and again, the process of adjusting the seat is described in detail:

s1: the button 262 is driven to make the unlocking piece 260 slide along the second direction until the boss 264 abuts against the wall of the first chute;

s2: pressing the unlocking member 260 in the first direction makes the transmission member 250 slide synchronously, pushing against one end of the second linkage member 280 to drive the other end of the second linkage member 280 to rotate, the first linkage member 270 connected with the second linkage member to slide, and the corresponding locking pin 211 rotates and exits from the locking groove 111;

s3: the seat 200 is moved to the desired position and the button 262 is released near the corresponding latch slot 111, waiting for the latch pin 211 to align with the latch slot 111 and then automatically extending to complete the latching.

The utility model provides a child dinning chair is provided with two latch mechanisms that are used for adjusting the seat height, and food safety is higher. The two lock mechanisms utilize the original side block and are disassembled on the traditional transmission piece (the unlocking piece in the prior art), so that the elements to be added are reduced as much as possible, and the manufacturing cost is reduced.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.

The above examples only express several embodiments of the present application, and the description thereof is more specific and detailed, but not to be construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application.
