[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] See also Figure 1-Figure 7 , a folding chair, comprising a plurality of load-bearing parts 1, and further comprising:

[0035] A plurality of adjustable pillars 2, which are respectively mounted on the top of the load-bearing member 1 in a one-to-one correspondence;

[0036] A plurality of sliding members 3, which are respectively mounted on the outer sides of the adjustable pillars 2 in a one-to-one correspondence;

[0037] A plurality of side support rods 4, which are respectively installed on one side of the load-bearing member 1;

[0038] The folding assembly 5 is installed on the top of the plurality of adjustable pillars 2 .

[0039] Two rotation grooves 11 are symmetrically arranged on one side of the top of the load-bearing member 1 .

[0040] Specific implementation method: The load-bearing member 1 plays a supporting role, and its bottom material can be rubber to improve the stability of the folding chair on uneven ground and increase friction. The adjustable pillar 2 also plays a supporting role. At the same time, since it has the function of adjusting the length, the user can adjust the length to achieve the final height adjustment of the folding chair. During the adjustment process, the user can adjust different adjustable pillars 2 to different lengths, so that the supporting pad 54 tilts at a certain angle to adapt to the user's sitting posture preference. The rotation of the side support rod 4 causes the sliding member 3 to slide up and down, thereby realizing the folding function of the folding chair. The rotating groove 11 opened on the top of the load-bearing member 1 is used to rotatably install the side support rod 4.

[0041] Adjustable Strut 2 includes:

[0042] A main support rod 21, which is fixedly mounted on the other side of the top of the load-bearing member 1;

[0043] An adjusting sleeve 22, which is slidably connected to one end of the main support rod 21 and has a thread 23 on its inner side;

[0044] A threaded plate 24, which is threadedly connected to the inner side of the adjusting sleeve 22 through the thread 23, and the inner side of which is slidably connected to the outer side of the main support rod 21;

[0045] A support cylinder 25, which is fixedly mounted on the top of the threaded plate 24;

[0046] The main support rod 21 can extend into the inner cavity of the support tube 25 .

[0047] Specific implementation method: When adjusting the height of the folding chair, the user manually rotates the adjusting sleeve 22 so that the thread 23 is released from the threaded connection with the threaded plate 24. The threaded plate 24 is made of soft material and can be deformed to a certain extent. After the threaded connection between the thread 23 and the threaded plate 24 is released, the threaded plate 24 expands outward to restore its original state. The user manually pulls the main support rod 21 until it extends out of the support tube 25 to an appropriate length. At this time, the adjusting sleeve 22 is rotated in the opposite direction to make the thread 23 threadedly connected with the threaded plate 24. During the rotation process, the threaded plate 24 is squeezed inwardly, so that the threaded plate 24 shrinks inward and is in close contact with the main support rod 21, increasing the distance between the two. The friction between them ultimately plays a role of stable support. For people with different sitting preferences, users can adjust the extended length of the main support rod 21. If the extended lengths of several main support rods 21 are the same, the folding chair can be raised or lowered as a whole. If the extended lengths of several main support rods 21 are different, the supporting pad 54 can be tilted to adapt to different usage scenarios. The outer sides of the main support rod 21 are slidingly connected to the inner sides of the adjustment sleeve 22 and the threaded plate 24 respectively, but do not contact the inner side of the support tube 25. The adjustment sleeve 22 and the threaded plate 24 are made of plastic non-slip material, which can increase the friction between them and the main support rod 21, while reducing the wear on the outer coating of the main support rod 21.

[0048] The sliding member 3 is slidably connected to the outside of the supporting tube 25 , and has two second rotation grooves 31 symmetrically formed on one side thereof.

[0049] One end of the side support rod 4 is rotatably connected to the inner side of a rotation groove 11 opened on one side of the load-bearing component 1, and the other end thereof is rotatably connected to the inner side of a rotation groove 2 31 opened on one side of a sliding component 3 installed on the outer side of an adjacent adjustable pillar 2, and the middle parts of the two side support rods 4 between two adjacent adjustable pillars 2 are rotatably connected.

[0050] Specific implementation method: When carrying the folding chair, the user rotates the two side support rods 4 between two adjacent adjustable pillars 2. Since the two side support rods 4 are rotatably connected in the middle, they can rotate, and one end of the side support rod 4 can rotate inside the rotation groove 11, and the other end can rotate inside the rotation groove 2 31. The folding function of the folding chair is achieved by rotating at three connection points. The structure is simple and easy to maintain, avoiding the defects of high failure rate and inconvenient maintenance caused by complex structure.

[0051] The folding assembly 5 includes: a plurality of rotating members 51, which are rotatably connected to the top of the support tube 25 one by one, and the inner side of the rotating member 51 is rotatably connected to an arc support member 52, and one side of the arc support member 52 is rotatably connected to a connecting member 53, and the connecting member 53 is rotatably connected to one side of an adjacent arc support member 52.

[0052] The folding assembly 5 further comprises a supporting pad 54 , and a plurality of collars 55 are fixedly mounted on the outer side of the supporting pad 54 , and the inner side of the collars 55 is movably connected to the outer side of the arc support member 52 .

[0053] Specific implementation method: The arc support member 52 is a 1 / 4 arc, which is connected to each other through a connecting member 53 to form a full circle, providing support for the supporting pad 54. During the folding process, since the distance between adjacent adjustable pillars 2 is continuously reduced, it is difficult for the arc support member 52 to maintain the state of being spliced ​​into a full circle. The arc support member 52 will rotate along the inner side of the rotating member 51, and rotate with the connecting member 53 at the same time, and also drive the rotating member 51 to flip outward to achieve the folding effect. When the folding chair is opened for use, the arc support member 52 will rotate along the inner side of the rotating member 51, and rotate with the connecting member 53 at the same time, and also drive the rotating member 51 to flip inward, and finally spliced ​​into a full circle.

[0054] The support pad 54 is made of double-layer 600D Oxford cloth with cotton in the middle, which improves comfort. At the same time, it is movably connected to the outer side of the arc support member 52 through the ring 55, has a certain degree of freedom of movement, and can adapt to slight movements of the user in a sitting state.

[0055] Working principle: in the carrying state, the user rotates the two side support rods 4 connected to each other, causing the sliding of the sliding part 3, thereby realizing the rotation of the rotating part 51 and the arc support part 52, and folding the supporting pad 54. At this time, the folding chair occupies less space, which is convenient for users to carry. At the same time, its structure is simple, avoiding the high failure rate and inconvenient maintenance defects caused by the complex structure. When using the folding chair, the user rotates the two side support rods 4 connected to each other in reverse to open the folding chair. The operation is simple. At the same time, for users of different heights, the folding chair can achieve height adjustment through the adjustable pillars 2. The adjustment mechanism is simple and has a low failure rate. During the adjustment process, the user can adjust different adjustable pillars 2 to different lengths, so that the supporting pad 54 tilts at a certain angle to adapt to the user's sitting posture preference. The supporting pad 54 has a certain degree of freedom of movement and can adapt to the user's slight movement in a sitting state. At the same time, it adopts a double-layer 600D Oxford cloth with cotton in the middle design to improve comfort.

[0056] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
