Description

Technical Field

[0001] This utility model relates to the technical field of dining chairs, and specifically to a novel dining chair. Background Technology

[0002] Dining chairs are commonly used furniture for children's meals. Ease of use, storage flexibility, and structural stability are core user requirements, with a particular emphasis on foldable, easily adjustable, and stable designs. However, existing dining chair technology still has the following shortcomings:

[0003] (1) Folding operation is cumbersome and the linkage is poor: Most existing foldable dining chairs adopt a "step-by-step folding" design, which requires separate operation of backrest flipping, leg storage, and plate disassembly / flipping. The steps are cumbersome and the linkage between the parts is weak. Parts are prone to jamming during the folding process, resulting in low storage efficiency.

[0004] (2) The unlocking mechanism is unreliable and difficult to operate: Most dining chair locking mechanisms require both hands to unlock, which is difficult to operate; and after long-term use, the buckles are prone to wear and the pins are prone to rust, which can lead to unlocking jams or even the safety hazard of being unable to lock.

[0005] (3) Inconvenient height adjustment and insufficient stability: Existing height-adjustable dining chairs require tools or forceful insertion and removal by hand for adjustment, which is inconvenient to operate; and the fixed structure is mostly single-point support, and the connection between the support leg and the height adjustment rod is not rigid enough after adjustment, which makes it easy to wobble when subjected to force, especially when bearing the weight of a child, which poses a risk of tipping over.

[0006] Therefore, there is an urgent need for a new type of dining chair that is easy to fold, has reliable linkage, and is height-adjustable. Utility Model Content

[0007] The technical problem to be solved by this utility model is to propose a new type of dining chair to address the above-mentioned shortcomings of the existing technology.

[0008] To achieve its purpose, this utility model adopts the following technical solution:

[0009] A novel dining chair includes: a seat, front legs, rear legs, a tray, an unlocking component, and a folding linkage component;

[0010] The seat includes a seat board and a backrest hinged to one end of the seat board. The front ends of both sides of the seat board are connected to the front support legs via long pins. The rear ends of both sides of the seat board are connected to the rear support legs via unlocking components. The backrest is hinged to both sides with traction rods.

[0011] The top of the front support leg, the top of the rear support leg, both ends of the tray, and the end of the traction rod away from the backrest are all connected to the folding linkage assembly.

[0012] The bottom of the base plate is provided with a mounting groove, and a baffle is provided in the mounting groove;

[0013] The unlocking assembly includes an unlocking button, a spring, and a short pin. The unlocking button is located in the mounting groove. One end of the spring is sleeved on the mounting protrusion inside the unlocking button, and the other end abuts against the baffle. One end of the short pin is connected to the outer end of the unlocking button, and the other end can enter and exit the positioning hole on the rear support leg.

[0014] Preferably, the folding linkage assembly includes a first rotating component, a second rotating component, a gear, and a housing. The first rotating component is connected to the dinner plate, the second rotating component is connected to the front support leg and the rear support leg, the gear is engaged between the first rotating component and the second rotating component, and the housing is fastened to the outside of the first rotating component.

[0015] The end of the traction rod away from the backrest is provided with a rotating disk, and two inclined top plates are provided on the outer end face of the rotating disk. The end face of the gear facing the rotating disk is provided with an inclined groove that cooperates with the inclined top plates.

[0016] Preferably, the gear has a retaining tooth on its outer circumference, the retaining tooth including a straight tooth portion and a helical tooth portion; the inner side of the first rotating member has a straight tooth groove that mates with the straight tooth portion of the retaining tooth; the inner side of the second rotating member has a helical tooth groove that mates with the helical tooth portion of the retaining tooth.

[0017] Preferably, the front and rear outriggers are equipped with height adjustment rods inside to adjust the height of the front and rear outriggers.

[0018] Preferably, the upper end of the height adjustment rod is provided with a spring buckle, and the front and rear support legs are provided with a number of limiting holes, and the spring buckle enters and exits the limiting holes.

[0019] Preferably, the bottom of the height adjustment rod is connected to a support plate.

[0020] The beneficial effects of this utility model are:

[0021] (1) Folding is efficient and convenient, and storage is flexible: This utility model achieves the synchronous folding of the backrest, front support legs, rear support legs and plate by integrating the design of "folding linkage component + traction rod". Only by pressing the unlock button, the short pin shaft moves out of the positioning hole, so that the seat plate and the rear support leg are unlocked. Flipping the seat plate drives the backrest and traction rod to rotate. The inclined top plate on the rotating plate pushes the gear to leave the inclined tooth groove of the second rotating part, and the first rotating part and the second rotating part can rotate, thereby driving the support legs and plate to be stored synchronously. The folding steps are simplified to 2 steps, and the efficiency is significantly improved.

[0022] (2) The unlocking operation is effortless and highly reliable: The unlocking component adopts an elastic reset structure of "button + spring + short pin". The unlocking button can be pressed with a single finger, and the spring provides a stable reset force to ensure that the short pin and the rear support leg positioning hole are precisely matched.

[0023] (3) Flexible height adjustment and stable use: The height adjustment rods built into the front and rear outriggers are combined with the "spring buckle + multi-position limit hole" design, which can be adjusted with one hand without tools; after the spring buckle is inserted into the limit hole, it forms a two-point positioning, which, together with the anti-slip support plate at the bottom of the height adjustment rod, improves the overall load-bearing stability and avoids tipping or shaking.
