TECHNICAL FIELD

[0001] The utility model relates to children's dining chair technical field, concretely relates to a kind of detachable novel connecting structure of children's dining chair tray. BACKGROUND

[0002] Children's dining chair is the common tool that children play, study and eat and feed conveniently for children. The existing children's dining chair includes chair frame, support and tray, support is generally set on chair frame as handrail, and tray is installed on support. In the prior art, part of tray is set as rotatable connection mode, and another part of tray is set as detachable connection mode. Although rotatable connection mode is more convenient and fast in use, saves support structure, and increases active space, it is more complicated when cleaning, so most people will choose detachable connection mode when selecting dining chair. However, the detachable structure of tray in the prior art is more complex, and it is more troublesome to disassemble and assemble. For example, the detachable connecting structure of children's dining chair tray disclosed in the prior art authorization announcement CN210810164U realizes detachable connection by setting buckle that can be extended on support, and by clamping buckle between positioning sleeve. This structure is not flexible in operation, and it is difficult to disassemble and replace when buckle loses restoring force inside support. It must be replaced together with support, which is high in cost and inconvenient in operation. Therefore, the above structure is improved, and a detachable novel connecting structure of children's dining chair tray is proposed. CONTENT OF UTILITY MODEL

[0006] A children's dining chair body is provided with symmetrical supports on the upper part in transverse direction.

[0007] A tray is connected with the supports.

[0008] The tray and the supports are detachably connected through limiting lock. A positioning slot is formed in the inner side of the support. The limiting lock comprises a lock disc and a movable piece. The lock disc is fixed on the bottom of the tray, and a sliding groove is formed in the middle of the lock disc. The two sides of the sliding groove form sliding rails, and a sliding hole is formed in the middle of the lock disc body. The movable piece comprises a positioning buckle, a protruding part and a push handle part, and is an integral structure. The protruding part is located behind the positioning buckle, and a slide channel is formed below the two. The slide channel can slide along the sliding rails. The push handle part passes through the sliding hole and can slide along the sliding hole to drive the positioning buckle to insert or separate from the positioning slot.

[0009] As a further improvement of the scheme, the mounting screw holes are arranged at four corners of the locking disc, and the locking disc and the dinner plate are fixedly connected through the mounting screw holes.

[0010] As a further improvement of the scheme, the bracket is a hollow structure.

[0011] As a further improvement of the scheme, the limiting lock is a plastic part.

[0012] As a further improvement of the scheme, the spring is further arranged between the convex part and the dinner plate.

[0013] Compared with the prior art, the dinner plate and the bracket are detachably connected through the limiting lock. The limiting lock structure adopts a horizontal locking buckle mode of the locking disc and the movable part, and has the advantages of simple structure, low cost, flexible operation, quick replacement of the limiting lock when the limiting lock is damaged, and the like. Compared with the vertical ring buckle clamping and detaching mode of the prior art, the limiting lock structure is independent, and is quick to replace when damaged. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0029] EMBODIMENT

[0030] As Figures 1-12 shown, the embodiment provides a new type of detachable connecting structure of a dining plate of a child dining chair, which comprises a child dining chair body 1 and a dining plate 2. The upper part of the child dining chair body 1 is provided with symmetrical supports 11. The support 11 is a hollow structure, and the material is a steel structure or a plastic part. The support 11 is preferably a cylindrical structure.

[0031] The dining plate 2 and the support 11 are detachably connected through a limiting lock 3. The inner side of the support 11 is provided with a positioning slot 111. The limiting lock 3 comprises a lock disc 31 and a movable part 32. The lock disc 31 is fixed at the bottom of the dining plate 2. The middle part of the lock disc 31 is provided with a sliding groove 310, and the two sides of the sliding groove 310 form a sliding rail 313. The middle part of the sliding groove 310 is provided with a sliding hole 311 in the body of the lock disc 31. The movable part 32 comprises a positioning buckle 321, a protruding part 322 and a push hand 320, and is an integral structure. The protruding part 322 is located behind the positioning buckle 321, and a slide 323 is formed below the two. The slide 323 can slide along the sliding rail 313. The push hand 320 passes through the sliding hole 311 and can slide along the sliding hole 311 to drive the positioning buckle 321 to insert or separate from the positioning slot 111.

[0032] The lock disc 31 is provided with a mounting screw hole 312 at the four corners. The lock disc 31 and the dining plate 2 are fixedly connected through the mounting screw hole 312.

[0033] In the specific installation, the limiting lock 3 is a plastic piece, the lock disc 31 and the tray 2 are fixedly connected by the screw through the installation screw hole 312, in the installation, the push hand part 320 is pushed backward, the end surface of the lock disc 31 is tightly attached to the support 11, after the lock disc 31 is installed, the specific operation principle is that the push hand part 320 is pushed forward through the sliding hole 311, the sliding groove 323 formed between the convex part 322 and the positioning plug 321 slides on the sliding rail 313, the positioning plug 321 is pushed into the positioning slot 111 on the support 11 to complete the locking, when the connection between the tray 2 and the support 11 needs to be disassembled, the push hand part 320 is pushed in the opposite direction, and the positioning plug 321 is separated from the positioning slot 111, then the tray 2 is taken upward to complete the separation. The limiting lock 3 is a plastic piece, the manufacturing cost is low. The tray and the support are detachably connected through the limiting lock. The limiting lock structure adopts the transverse lock buckle mode of the lock disc and the movable piece, the structure is simple, the limiting lock is directly disassembled and replaced by the bolt when the limiting lock is damaged, the cost is low, the operation is flexible and convenient. Compared with the vertical ring buckle clamping and disassembling mode of the prior art, the limiting lock structure is more quick and flexible, and the limiting lock structure is independent, and the damage and replacement are quick.

[0034] In other embodiments, a spring (not shown in the figure) is further installed between the end, away from the positioning plug 321, of the convex part 322 and the tray 2. The positioning plug 321 can automatically enter the positioning slot 111 through the action of the spring, only the push hand part 320 needs to be pushed when disassembled, and the operation is more flexible.
