Technical Field

[0001] This utility model relates to the field of dining chair technology, and in particular to a portable folding dining chair. Background Technology

[0002] With social development and improved living standards, portable furniture has gradually gained popularity, among which portable folding dining chairs are particularly common in homes and outdoors.

[0003] Existing portable dining chairs are usually cumbersome to fold and unfold, have an insufficiently compact structural design, and lack stability. In addition, many existing portable dining chairs are inconvenient to disassemble and clean, making it difficult to meet users' needs for hygiene and convenience.

[0004] Therefore, designing a portable folding dining chair that is simple to operate, compact in structure, safe to use, and easy to clean has become an urgent problem to be solved.

[0005] Therefore, we propose a portable folding dining chair to solve the existing problems. Utility Model Content

[0006] The purpose of this invention is to address the problems existing in the background technology by proposing a portable folding dining chair.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable folding dining chair, comprising a front support leg, a rear support leg, a seat plate, a backrest plate, a connecting plate, and a shaft head. The front support leg, the connecting plate, and the shaft head are coaxially rotatably connected via a shaft rod. The other end of the connecting plate is rotatably connected to the upper end of the backrest plate. The bottom end of the backrest plate is rotatably mounted on the seat plate. The seat plate is rotatably connected to the front support leg, and the rear support leg is rotatably connected to the front support leg. A sliding rod is provided on the seat plate, and an arc-shaped sliding track is provided on the rear support leg. The sliding rod is slidably mounted on the arc-shaped sliding track. A dining board is movably inserted into the shaft head via a plug-in assembly. Two sets of support assemblies are symmetrically arranged on the lower surface of the seat plate, and the working ends of the support assemblies are plugged into the rear support legs.

[0008] Preferably, the plug-in assembly consists of a pressure block and an inner spring. The pressure block is slidably disposed on the lower surface of the shaft head, and the inner spring is disposed inside the pressure block. One end of the inner spring abuts against the lower surface of the shaft head, and the other end of the inner spring abuts against the bottom end of the inner wall of the pressure block. The original length of the inner spring is greater than the height of the pressure block.

[0009] Preferably, the end of the plate that is inserted into the shaft head has a notch, and the pressure block extends into the notch under the action of the inner spring.

[0010] Preferably, the support assembly consists of a base plate, a limiting block, a limiting hole, a limiting head, and an outer spring, with the limiting holes symmetrically opened on the rear support leg.

[0011] Preferably, the base plate is bolted to the lower surface of the seat plate, the limiting block is slidably disposed on the base plate, one end of the outer spring abuts against the base plate, and the other end of the outer spring abuts against the limiting block.

[0012] Preferably, the limiting head is located at the end of the outer wall of the limiting block, and the limiting head corresponds to the limiting hole.

[0013] Preferably, one end of the limiting block is provided with a lever, and the bottom end of the lever protrudes from the lower surface of the substrate.

[0014] Preferably, the lower surfaces of the front and rear outriggers are provided with rubber pads, which are symmetrically distributed on the lower surfaces of the front and rear outriggers, respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] When this portable folding dining chair is needed, the device is unfolded through the rotational connection between the various structures. During the unfolding process, the slide rod slides in the arc-shaped slide, and the limiting head gradually approaches the limiting hole. When the device is fully unfolded, the limiting head and the limiting hole are in the same position. Then, under the elastic force of the outer spring, the limiting block slides on the base plate, so that the limiting head is inserted into the limiting hole, thereby providing support for the seat plate.

[0017] Then rotate the spindle head to make the food board horizontal, then place the child on the seat board, put the food on the food board, and you can feed the child.

[0018] Furthermore, when the dining chair needs to be folded and stored, the person applies force to the lever of the limiting block, so that the two limiting blocks come closer to each other. At this time, the limiting block compresses the spring and deforms until the limiting head disengages from the limiting hole, and the device can then be folded and stored.

[0019] Furthermore, when it is necessary to clean or replace the tabletop, the insertion component is used. Personnel press the pressure block with their fingers to retract the pressure block into the shaft head and away from the tabletop. At this time, the tabletop can be pulled off the shaft head, thus completing the disassembly of the tabletop.

[0020] This utility model features a convenient folding and unfolding design. The portable folding dining chair achieves easy folding and unfolding through a clever rotating connection between the front and rear legs, seat, and backrest, as well as the cooperation of the sliding rod and the arc-shaped slide rail. During unfolding, the limiting head and limiting hole automatically position themselves through the action of an external spring, providing solid support. Operation is convenient and efficient. The plug-in assembly allows for quick disassembly of the dining board through elastic pressure blocks, making cleaning and replacement more convenient and meeting hygiene requirements.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] like Figures 1-6As shown, the present invention proposes a portable folding dining chair, including a front support leg 1, a rear support leg 2, a seat plate 3, a backrest plate 4, a connecting plate 5, and a shaft head 6. The front support leg 1, the connecting plate 5, and the shaft head 6 are coaxially rotatably connected by a shaft rod 8. The other end of the connecting plate 5 is rotatably connected to the upper end of the backrest plate 4. The bottom end of the backrest plate 4 is rotatably mounted on the seat plate 3. The seat plate 3 is rotatably connected to the front support leg 1, and the rear support leg 2 is rotatably connected to the front support leg 1. The seat plate 3 is provided with a sliding rod 9, and the rear support leg 2 is provided with an arc-shaped slide rail 10. The sliding rod 9 is slidably mounted on the arc-shaped slide rail 10. A dining board 7 is movably inserted into the shaft head 6 through a plug-in assembly. Two sets of support assemblies are symmetrically arranged on the lower surface of the seat plate 3, and the working ends of the support assemblies are plugged into the rear support leg 2.

[0032] Based on Example 1:

[0033] When this portable folding dining chair is needed, the device is unfolded through the rotational connection between the various structures. During the unfolding process, the slide bar 9 slides in the arc-shaped slide rail 10. At this time, the limiting head 16 gradually approaches the limiting hole 13. When the device is fully unfolded, the limiting head 16 corresponds to the limiting hole 13. Then, under the elastic force of the outer spring 17, the limiting block 12 slides on the base plate 11, so that the limiting head 16 is inserted into the limiting hole 13, thereby providing support for the seat plate 3.

[0034] Then rotate the shaft head 6 to make the food board 7 horizontal. Then place the child on the seat board 3 and place the food on the food board 7 to feed the child.

[0035] Furthermore, when the dining chair needs to be folded and stored, the person applies force to the lever of the limiting block 12, so that the two limiting blocks 12 move closer to each other. At this time, the limiting block 12 compresses the outer spring 17 and deforms until the limiting head 16 disengages from the limiting hole 13, and the device can be folded and stored.

[0036] Furthermore, when it is necessary to clean or replace the plate 7, the insertion component is used. Personnel press the pressure block 14 with their fingers to retract the pressure block 14 into the shaft head 6 and away from the plate 7. At this time, the plate 7 can be pulled off the shaft head 6, thus completing the disassembly of the plate 7.

[0037] Example 2

[0038] like Figures 1-6As shown, the portable folding dining chair proposed in this utility model, compared with Embodiment 1, further includes: a support assembly consisting of a base plate 11, a limiting block 12, a limiting hole 13, a limiting head 16, and an outer spring 17. The limiting holes 13 are symmetrically opened on the rear support legs 2. The base plate 11 is bolted to the lower surface of the seat plate 3. The limiting block 12 is slidably disposed on the base plate 11. One end of the outer spring 17 abuts against the base plate 11, and the other end of the outer spring 17 abuts against the limiting block 12. The limiting head 16 is located at the end of the outer wall of the limiting block 12. The limiting head 16 corresponds to the limiting hole 13. During the unfolding process, the slide rod 9 slides in the arc-shaped slide 10. At this time, the limiting head 16 gradually approaches the limiting hole 13. When the device is fully unfolded, the limiting head 16 corresponds to the limiting hole 13. Then, under the elastic force of the outer spring 17, the limiting block 12 slides on the base plate 11, so that the limiting head 16 is inserted into the limiting hole 13, thereby providing support force for the base plate 3.

[0039] When folding and storing the dining chair, the person applies force to the lever of the limiting block 12, causing the two limiting blocks 12 to move closer to each other. At this time, the limiting block 12 compresses the outer spring 17 and deforms until the limiting head 16 disengages from the limiting hole 13, and the device can then be folded and stored.

[0040] One end of the limiting block 12 is provided with a lever. The bottom end of the lever protrudes from the lower surface of the base plate 11. The lever is easy to operate. Users can release the locking of the limiting block 12 by applying light force, making it convenient to fold and store.

[0041] The insertion assembly consists of a pressure block 14 and an inner spring 15. The pressure block 14 is slidably disposed on the lower surface of the shaft head 6, and the inner spring 15 is disposed inside the pressure block 14. One end of the inner spring 15 abuts against the lower surface of the shaft head 6, and the other end of the inner spring 15 abuts against the bottom end of the inner wall of the pressure block 14. The original length of the inner spring 15 is greater than the height of the pressure block 14. The end of the tableware 7 that is inserted into the shaft head 6 has a notch. Under the action of the inner spring 15, the pressure block 14 extends into the notch. When a person presses the pressure block 14 with their fingers, the pressure block 14 retracts into the shaft head 6 and moves away from the tableware 7. At this time, the tableware 7 can be pulled off the shaft head 6, thus completing the disassembly of the tableware 7.

[0042] Both the front outrigger 1 and the rear outrigger 2 are equipped with rubber pads on their lower surfaces, which are symmetrically distributed on the lower surfaces of the front outrigger 1 and the rear outrigger 2.
