Description

Technical Field

[0001] This utility model belongs to the field of children's dining chair technology, and in particular relates to a children's dining chair with an adjustable tray. Background Technology

[0002] A high chair is a special seat designed for infants and preschool children, mainly used to assist children in eating. Currently, most high chairs on the market come with a tray.

[0003] Most common children's high chairs currently use a fixed tray design. However, there are individual differences among children, and their body sizes vary. As children grow rapidly, their body sizes change continuously, and the fixed tray cannot flexibly adapt to their body shape. This results in the tray being too close or too far away during use. Therefore, there is a need for a children's high chair with an adjustable tray. The tray position can be adjusted through a sliding locking structure to adapt to children of different body sizes and optimize their eating posture. Utility Model Content

[0004] The purpose of this invention is to provide a children's dining chair with an adjustable tray, which allows the tray position to be adjusted via a sliding locking structure, thereby adapting to children of different sizes and optimizing their eating posture, in order to solve the aforementioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A children's dining chair with an adjustable plate, comprising: two symmetrical limiting slide grooves fixedly connected to the surface of the children's dining chair; a plate is provided at the top of the limiting slide groove; a sliding rod is fixedly connected to the inner wall of the limiting slide groove; a slider is sleeved on the surface of the sliding rod; the slider is slidably connected to the sliding rod; two symmetrical connecting plates are provided between the two limiting slide grooves; the connecting plates are fixedly connected to the sliders and the plate; a slot is opened on the opposite side of the two limiting slide grooves; a locking hole is opened on the opposite side of the two sliders; the locking hole extends to the inner cavity of the sliding hole on the surface of the slider; the locking hole communicates with the sliding hole on the surface of the slider; a threaded sleeve is fixedly connected to the side of the locking hole; a locking bolt is threadedly connected to the inner wall of the threaded sleeve; one end of the locking bolt passes through the locking hole.

[0006] Preferably, the surface of the children's high chair is fixedly connected to two symmetrical limiting rods, and the bottom of the limiting rods is fixedly connected to a limiting circular block.

[0007] Preferably, a foot pedal is provided between the two legs of the children's dining chair, and the limiting rod passes through the foot pedal and is slidably connected to the foot pedal.

[0008] Preferably, the back of the foot pedal has two symmetrical threaded holes that extend into the inner cavity of the through hole on the surface of the foot pedal and are connected to the through hole on the surface of the foot pedal.

[0009] Preferably, the inner wall of the threaded hole is threaded with a locking bolt, one end of which extends through a through hole on the surface of the foot pedal.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model adjusts the position of the plate by pulling it forward, causing the plate to slide forward on the surface of the sliding rod via the connecting plate. Rotating the locking bolt makes one end of the locking bolt contact the surface of the sliding rod, and then tightening the locking bolt through the threaded sleeve increases the lateral pressure and friction of the locking bolt on the sliding rod, thereby locking the slider on the surface of the sliding rod. This achieves the purpose of adjusting the position of the plate through the sliding locking structure, thus adapting to children of different sizes and optimizing their eating posture.

[0012] 2. This utility model uses a combination of a limiting rod, a foot pedal, a threaded hole, and a locking bolt. By sliding the foot pedal on the surface of the limiting rod up and down, the height of the foot pedal can be adjusted. At this time, the locking bolt in the inner cavity of the threaded hole is tightened, so that one end of the locking bolt contacts the limiting rod in the through hole of the foot pedal. This causes the locking bolt to apply pressure and friction to the limiting rod, thereby locking the foot pedal. Attached Figure Description

[0021] In the following description, embodiments of the children's high chair with an adjustable tray of the present invention will be described with reference to the accompanying drawings.

[0022] Figures 1-5 This invention illustrates a children's high chair with an adjustable tray according to an embodiment of the present invention. The high chair includes a children's high chair 1. Two symmetrical limiting grooves 3 are fixedly connected to the surface of the high chair 1. Two symmetrical limiting rods 11 are also fixedly connected to the surface of the high chair 1. Through the cooperation of the limiting rods 11, foot pedals 12, threaded holes 13, and locking bolts 14, the height of the foot pedals 12 can be adjusted by sliding them up and down on the surface of the limiting rods 11. At this time, the locking bolts 14 are tightened in the inner cavity of the threaded holes 13, so that one end of the locking bolts 14 contacts the limiting rods 11 through the holes of the foot pedals 12. This causes the locking bolts 14 to apply pressure and friction to the limiting rods 11, thereby locking the foot pedals 12. A limiting circular block is fixedly connected to the bottom of the limiting rods 11. A foot pedal 12 is provided between the two legs of the high chair 1. Two symmetrical threaded holes 13 are opened on the back of the foot pedals 12, extending into the inner cavity of the through holes on the surface of the foot pedals 12. A locking bolt 14 is threadedly connected to the inner wall of the threaded hole 13. One end of the locking bolt 14 passes through a through hole on the surface of the foot pedal 12. The threaded hole 13 communicates with the through hole on the surface of the foot pedal 12. A limiting rod 11 passes through the foot pedal 12 and is slidably connected to the foot pedal 12. A plate 2 is provided at the top of the limiting slide groove 3. A sliding rod 4 is fixedly connected to the inner wall of the limiting slide groove 3. A slider 5 is sleeved on the surface of the sliding rod 4. The slider 5 is slidably connected to the sliding rod 4. A space is provided between the two limiting slide grooves 3. Two symmetrical connecting plates 6 are fixedly connected to the slider 5 and the plate 2. The two limiting slides 3 have slots 7 on opposite sides. The two sliders 5 have locking holes 8 on opposite sides. The locking holes 8 extend into the inner cavity of the sliding hole on the surface of the slider 5. The locking holes 8 communicate with the sliding hole on the surface of the slider 5. A threaded sleeve 9 is fixedly connected to the side of the locking hole 8. A locking bolt 10 is threadedly connected to the inner wall of the threaded sleeve 9. One end of the locking bolt 10 passes through the locking hole 8.

[0023] Working Principle: When using this invention, the user pulls the plate 2 forward. Since the plate 2 is fixedly connected to the connecting plate 6, and the connecting plate 6 is fixedly connected to the slider 5, and the slider 5 is slidably connected to the sliding rod 4, the plate 2, through the connecting plate 6, causes the slider 5 to slide forward on the surface of the sliding rod 4, thereby adjusting the position of the plate 2. At this time, rotating the locking bolt 10 causes one end of the locking bolt 10 to contact the surface of the sliding rod 4 because the locking hole 8 communicates with the sliding hole on the surface of the slider 5, and the sliding rod 4 passes through the slider 5. The locking bolt 10 is then tightened through the threaded sleeve 9, increasing the lateral pressure and friction of the locking bolt 10 on the sliding rod 4. This locks the slider 5 on the surface of the slide bar 4, allowing the position of the slide bar 4 to be adjusted via the sliding locking structure. This adapts to children of different sizes and optimizes their dining posture. Through the combined use of the limiting rod 11, foot pedal 12, threaded hole 13, and locking bolt 14, the height of the foot pedal 12 is adjusted by sliding the foot pedal 12 on the surface of the limiting rod 11 up and down. At this time, the locking bolt 14 in the inner cavity of the threaded hole 13 is tightened, so that one end of the locking bolt 14 contacts the limiting rod 11 in the through hole of the foot pedal 12. This causes the locking bolt 14 to apply pressure and friction to the limiting rod 11, thereby locking the foot pedal 12.

[0024] In summary, this children's high chair with an adjustable tray allows for adjustment of the tray's position by pulling the tray 2 forward, causing the slider 5 to slide forward on the surface of the slide rod 4 via the connecting plate 6. Rotating the locking bolt 10 brings one end of it into contact with the surface of the slide rod 4, and tightening the locking bolt 10 via the threaded sleeve 9 increases lateral pressure and friction on the slide rod 4, thus locking the slider 5 on the surface of the slide rod 4. This sliding locking structure allows for adjustment of the tray's position, adapting it to children of different sizes and optimizing their eating posture.
