Description

Technical Field

[0001] The utility model relates to the technical field of infant products, in particular to a height-adjustable home dining chair. Background Art

[0002] Early home dining chairs were relatively simple in design, usually with a basic seat structure made of wood or metal. Their main function was to provide people with a seat for dining. With the improvement of people's living standards and the pursuit of quality of life, the design of home dining chairs has gradually developed towards functional diversification.

[0003] Currently, in the existing technology, traditional home dining chairs are usually fixed structures and occupy a certain amount of space even when not in use. This is a rather troublesome problem for families with limited living space. In addition, the adaptability to different age groups and usage scenarios is still limited. For example, ordinary dining chairs may not meet the dining needs of infants and young children, and special infant dining chairs need to be purchased separately. In view of this, we propose a height-adjustable home dining chair. Utility Model Content

[0004] The main purpose of the present invention is to provide a height-adjustable home dining chair that can solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention proposes a height-adjustable home dining chair, comprising a base, a lower surface of the base being rotatably connected to a roller, a slidably connected educational component on the base, the base being detachably connected to a dining chair body via an upper and lower interlaced structure, the dining chair body being movably connected to the detachable component via a rotating component, a height adjustment device being provided on the base, an adjustment and accommodation device being provided within the base, the height adjustment device comprising:

[0006] A slideway is provided on the surface of the base, a sliding groove is provided in the slideway, and a sliding plate is slidably connected to the sliding groove;

[0007] The flip plate is clamped with the sliding plate, and the flip plate is fixedly connected to the multi-speed armrest. The multi-speed armrest is provided with two groups, and the two groups of multi-speed armrests are rotatably connected with dual-purpose plates.

[0008] Preferably, the educational component includes an oblique groove, and the inner wall of the base is provided with an oblique groove, and the oblique groove is provided with three groups, and the three groups of oblique grooves are respectively slidably connected with an erasable drawing board, a splicing building block board and a magnetic puzzle board. When the infant wants to draw, the erasable drawing board can be placed in the third group on the innermost side of the oblique groove. The inclination angle of the oblique groove is convenient for the infant to draw on it. After the painting is completed, the painting can be erased using a matching erasing tool. The infant also places the splicing building block board in the middle group of the oblique groove, and then splices building blocks of different shapes according to his imagination and creativity. When it is necessary to play a puzzle, the magnetic puzzle board is placed in the outermost group of oblique grooves. Due to the magnetic properties of the magnetic puzzle board itself, the puzzle pieces can be adsorbed on the board, which is convenient for the infant to perform the puzzle operation.

[0009] Preferably, the upper and lower interlaced structures include a give way slot 1, a give way slot 1 and a give way slot 2 are provided on the surface of the base, the give way slot 1 is connected with an interlaced plate, a movable block is fixedly connected to the interlaced plate, the movable block is rotatably connected to the dining chair body, and a split movable switch is elastically provided on the movable block. In the high-leg dining chair mode, there is 180mm of thigh space, 180mm of calf space, 330mm of chair back height, 215mm of first gear seat depth, 250mm of second gear seat depth, and 285mm of third gear seat depth, which is in line with ergonomic design. The inserting plate slides forward in the chair-type state for use as a footrest. By pressing the movable switch, the clamping relationship between the inserting plate and the first clearance slot is released, and the inserting plate is changed from being clamped in the first clearance slot to being clamped in the second clearance slot. The high-legged dining chair is switched to the chair-type dining chair mode. The movable switch is released to realize the clamping connection between the inserting plate and the second clearance slot. It is suitable for self-adjustment of height in different environments, which is convenient for infants and young children to dine. The clamping relationship of the inserting plate is disassembled separately, and the movable block is directly rotated to drive the rotation of the inserting plate. The Z shape is straightened, and the two sets of inserting plates are placed on the ground. The dining chair body is switched from the high-legged dining chair to the small chair-type dining chair mode.

[0010] Preferably, mounting holes are provided on the surface of the dining chair body, and there are five groups of mounting holes. The five-point safety belts are fixedly connected to the mounting holes, and the infant is fixed through the connection points of the five mounting holes, respectively on both sides of the shoulders, both sides of the waist and the crotch, which can effectively prevent the infant from slipping off the dining chair body or breaking free from the safety belts, and provides more comprehensive protection than three-point safety belts.

[0011] The cam is engaged with the locking slot and the locking slot is communicated with the through slot, and the through slot is sleeved on the fixing frame, and the through slot is provided on the outer wall of the connecting seat. When the locking block moves to the locking slot position, the locking block will be engaged with the locking slot, and the fixing frame passes through the through slot, thereby realizing the connection between the connecting seat and the dining chair body. When the armrest rotary switch is rotated, the fixing frame will rotate accordingly, and the locking block on the fixing frame drives the connecting seat to flip through the locking slot. When the fixing frame flips upward and is at the same horizontal line with the inclined plate of the dining chair body, the non-dining mode serves as an armrest to assist infants and young children to stand. When the fixing frame flips upward and forms a triangular fixed structure with the flipped interlaced plate, the non-dining mode serves as a support and will not shake or shift during use, making it convenient for infants and young children to eat.

[0012] Preferably, the detachable component includes a connecting seat, the upper surface of which is provided with a plate receiving surface, and the connecting seat is engaged with the detachable plate through an arc-shaped clamping plate, the detachable plate is placed on the plate receiving surface of the connecting seat, and then the arc-shaped clamping plate is engaged with the corresponding structure on the connecting seat, so that the plate is fixed on the connecting seat. When disassembly is required, only a certain external force needs to be applied to release the engagement between the arc-shaped clamping plate and the connecting seat, and the detachable plate can be easily removed, which is convenient for disassembly and keeps the detachable plate clean and hygienic. At the same time, the connecting seat can also be disassembled as needed, which is convenient for cleaning and maintenance of the entire device.

[0013] Preferably, the adjustment and accommodating device includes an auxiliary plate, the inner wall of the base is fixedly connected to the auxiliary plate, the accommodating plate is slidably connected to the auxiliary plate, the inner wall of the base is provided with a limiting groove, the limiting groove is engaged with the limiting block, and the limiting block is fixedly connected to the partition.
