Description

Technical Field

[0001] This utility model belongs to the field of children's products technology, and relates to a footrest installation structure for a children's dining chair. Background Technology

[0002] Most existing children's high chairs have fixed, non-adjustable footrests, which cannot accommodate children of different ages and have a limited range of applications. While height-adjustable footrests have appeared on the market, their installation stability between the footrest and the chair's support legs is poor, and their installation structure is relatively complex, often requiring screw removal to adjust the footrest's height, making the adjustment process cumbersome. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a detachable and height-adjustable footrest mounting structure for a children's dining chair.

[0004] The objective of this utility model can be achieved through the following technical solution: A footrest mounting structure for a children's dining chair, comprising a footrest and multiple hollow support legs. Both ends of the footrest are connected to the support legs via a mounting structure. The mounting structure includes a mounting block and multiple U-shaped springs. The sides of the U-shaped springs are provided with positioning protrusions. The support legs are provided with multiple first positioning holes of different heights. The U-shaped springs are located inside the support legs. The ends of the positioning protrusions extend out of the first positioning holes, so that all the U-shaped springs are respectively mounted at different heights on the support legs. The mounting block is mounted on the end of the footrest. The mounting block is provided with mounting holes for the support legs to pass through. The sidewall of the mounting hole is provided with a second positioning hole. The mounting block is sleeved on the support legs, with the ends of the positioning protrusions extending out of the second positioning holes, thereby mounting the mounting block and the footrest onto the support legs.

[0005] In the footrest mounting structure of the aforementioned children's high chair, the mounting block has a mounting protrusion on its side, and a movable groove is formed on the mounting protrusion. Two spaced-apart insertion plates are provided in the movable groove. The opposing sides of the two insertion plates are provided with protruding locking blocks. A positioning step is formed between the locking blocks and the insertion plates. A guide slope is formed on the locking blocks. The end of the footrest is provided with a mounting groove. An insertion hole is formed on the groove wall of the mounting groove. The mounting protrusion is located in the mounting groove. Both insertion plates are inserted into the insertion holes. The locking blocks pass through the insertion holes.

[0006] In the foot pedal installation structure of the above-mentioned children's high chair, the bottom surface of the foot pedal is provided with a first disassembly hole that communicates with the insertion hole. The two insertion plates are moved relative to each other through the first disassembly hole, shortening the distance between the two locking blocks. At the same time, the mounting block is pulled outward, causing the locking block to disengage from the insertion hole, and the mounting block is removed from the foot pedal.

[0007] In the aforementioned footrest mounting structure of the children's high chair, the mounting protrusion has a second disassembly hole that communicates with the second positioning hole. By pressing the positioning protrusion through the second disassembly hole, the positioning protrusion is disassembled from the second positioning hole, thus completing the disassembly of the mounting block, the footrest, and the support leg.

[0008] Compared with existing technologies, the footrest mounting structure of this children's high chair allows for disassembly of the mounting block, footrest, and support leg by squeezing the positioning protrusion to disengage it from the second positioning hole. The elasticity of the U-shaped spring allows the positioning protrusion to quickly return to its original position. At this time, the footrest can move up and down relative to the support leg, allowing the mounting block to engage with the U-shaped springs of the remaining height to adjust the footrest height. The mounting block and footrest are engaged by a locking block and an insertion hole. The mounting protrusion on the mounting block provides force support for the footrest, ensuring a firm, stable, and reliable installation. The first disassembly hole facilitates the disassembly of the mounting block, and the second disassembly hole facilitates the squeezing of the positioning protrusion, making it easy to disassemble the footrest and adjust its height.

Detailed Implementation

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1-5 As shown, the footrest mounting structure of this children's high chair includes a footrest 1 and multiple hollow support legs 2. Both ends of the footrest 1 are connected to the support legs 2 via a mounting structure 3. The mounting structure 3 includes a mounting block 31 and multiple U-shaped spring pieces 32. The sides of the U-shaped spring pieces 32 are provided with positioning protrusions 33. The support legs 2 are provided with multiple first positioning holes 21 at different heights. The U-shaped spring pieces 32 are located inside the hollow support legs 2, and the ends of the positioning protrusions 33 extend out of the first positioning holes 21, so that all the U-shaped spring pieces 32 are respectively installed at different heights on the support legs 2. The mounting block 31 is installed at the end of the footrest 1. The mounting block 31 is provided with mounting holes 34 for the support legs 2 to pass through. The side wall of the mounting hole 34 is provided with second positioning holes 35. The mounting block 31 is sleeved on the support legs 2, and the ends of the positioning protrusions 33 extend out of the second positioning holes 35, thus installing the mounting block 31 and the footrest 1 onto the support legs 2. By squeezing the positioning protrusion 33 to disengage it from the second positioning hole 35, the disassembly of the mounting block 31, foot pedal 1 and support leg 2 can be completed. The elasticity of the U-shaped spring 32 allows the positioning protrusion 33 to quickly return to its original position. At this time, the foot pedal 1 can move up and down relative to the support leg 2, so that the mounting block 31 can cooperate with the U-shaped spring 32 of the remaining height to complete the height adjustment of the foot pedal 1.

[0017] In the above technical solution: the mounting block 31 has a mounting protrusion 36 on its side, and a movable groove 37 is formed on the mounting protrusion 36. Two spaced-apart insertion plates 38 are provided in the movable groove 37, and protruding locking blocks 39 are formed on the opposite sides of the two insertion plates 38. A positioning step 310 is formed between the locking block 39 and the insertion plate 38, and a guide slope 311 is formed on the locking block 39. The foot pedal 1 has a mounting groove 11 at its end, and an insertion hole 12 is formed on the groove wall of the mounting groove 11. The mounting protrusion 36 is located in the mounting groove 11. Both insertion plates 38 are inserted into the insertion hole 12. During the insertion process, the locking block 39 and the hole wall of the insertion hole 12 squeeze each other, causing the two insertion plates 38 to move relative to each other. The guide slope 311 plays a guiding role until the locking block 39 passes through the insertion hole 12. The two insertion plates 38 are reset. The positioning step 310 of the locking block 39 cooperates with the bottom surface of the mounting groove 11 to prevent the insertion plates 38 from falling out of the insertion hole 12, thus completing the installation between the mounting block 31 and the foot pedal 1.

[0018] In the above technical solution: the bottom surface of the foot pedal 1 is provided with a first disassembly hole 13 that communicates with the insertion hole 12. The two insertion plates 38 are moved relative to each other through the first disassembly hole 13, shortening the distance between the two locking blocks 39. At the same time, the mounting block 31 is pulled outward, and the locking block 39 is disengaged from the insertion hole 12, thereby removing the mounting block 31 from the foot pedal 1.

[0019] In the above technical solution: the mounting protrusion 36 has a second disassembly hole 312 that communicates with the second positioning hole 35. The positioning protrusion 33 is pressed through the second disassembly hole 312, causing it to disengage from the second positioning hole 35, thus completing the disassembly of the mounting block 31, the foot pedal 1, and the support leg 2. The second disassembly hole 312 facilitates the pressing of the positioning protrusion 33, and facilitates the disassembly and height adjustment of the foot pedal 1.

[0020] The footrest mounting structure of this children's high chair allows for disassembly of the mounting block 31, footrest 1, and support leg 2 by pressing the positioning protrusion 33 to disengage it from the second positioning hole 35. The elasticity of the U-shaped spring 32 allows the positioning protrusion 33 to quickly return to its original position. At this time, the footrest 1 can move up and down relative to the support leg 2, allowing the mounting block 31 to engage with the U-shaped spring 32 at other heights, thus adjusting the height of the footrest 1. The mounting block 31 and footrest 1 are engaged by the engagement of the locking block 39 and the insertion hole 12. The mounting protrusion 36 on the mounting block 31 provides force support for the footrest 1, ensuring that the footrest 1 is firmly, stably, and reliably installed. The first disassembly hole 13 facilitates the disassembly of the mounting block 31, and the second disassembly hole 312 facilitates the pressing of the positioning protrusion 33, making it convenient for the disassembly and height adjustment of the footrest 1.
