Description

Technical Field

[0001] The utility model relates to the technical field of folding chairs, in particular to a support structure of a folding chair with rotating and shaking functions. Background Art

[0002] At present, the folding chairs sold on the market are generally made of Oxford cloth or plastic board. Among them, Oxford cloth folding chairs are more convenient to carry and are often used for outdoor leisure camping. Oxford cloth folding chairs are mainly composed of steel pipes and Oxford cloth. The surface of the steel pipe is sprayed with plastic, which is rust-proof and beautiful. In addition, the important parts of the force are processed with process mechanics, and the load-bearing capacity is greatly enhanced. The specifications of Oxford cloth are mainly 600D or 800D, which improves the service life and comfort of the seat surface.

[0003] For example, the patent with publication number CN220308735U discloses an integrated folding chair, including a seat cover, a seat cover support tube and a support foot, the seat cover is made of Oxford cloth, there are four support feet arranged in front, back, left and right, the upper ends of the four support feet are rotatably connected through connecting seats, there are four seat cover support tubes corresponding to the support feet, the lower ends of the seat cover support tubes are rotatably mounted on the outer side of the support foot through joints, the upper ends of the seat cover support tubes are connected to the seat cover, the seat cover support tubes are telescopic tubes, and the outer side surface of the support foot is formed with a strip groove along the length direction for the seat cover support tube to be inserted after being retracted and folded;

[0004] The problem with the above technology is that after the folding chair is unfolded, the seat cover support tube and the support leg are relatively still. When the user sits on the folding chair, the back is supported by the Oxford cloth. The angle of the user's backward leaning is affected by the deformation of the Oxford cloth. In order to better support the user's back, the deformation of the Oxford cloth is generally small, and the user needs to stand up and then adjust the seat angle when adjusting the seat angle. The seat has a small range of motion, which is not convenient for some users with mobility problems or older users.

[0005] Therefore, a support structure of a folding chair that can be tilted backward and rotated is proposed to solve the above technical problems. Utility Model Content

[0028] Reference Figures 1 to 5 A support structure of a folding chair with a rotating and shaking function, comprising a fixed seat 1, a rotating seat 2 rotating on a horizontal plane is rotatably connected to the top of the fixed seat 1, a connecting seat 3 rotating on a vertical plane is rotatably connected to the rotating seat 2, and a spring 4 is arranged between the connecting seat 3 and the rotating seat 2;

[0029] The support structure of the folding chair can adjust the angle of the seat and increase the range of motion of the seat by rotating the rotating seat 2 relative to the fixed seat 1 on the horizontal plane to drive the connecting seat 3 to rotate. When the connecting seat 3 rotates on the vertical plane relative to the rotating seat 2, the spring 4 is squeezed. The spring 4 can give the user a buffering feeling to prevent the connecting seat 3 from tilting too much. The support structure can adjust the tilt angle of the seat according to the user's sitting posture, giving the user a better use experience. At the same time, the support structure is compact and light, which is easy for users to carry and suitable for outdoor activities.

When the user leans forward, the connecting seat 3 and the rotating seat 2 are relatively still, and the front side wall of the second axle seat 21 is always in contact with the inner side wall of the accommodating cavity 31. The seat can be tilted forward, providing the user with safer use.

[0033] In the preferred embodiment, a groove 211 is provided on the second shaft seat 21, and the first shaft seat 32 is movably provided in the groove 211. This structure can shorten the distance between the connecting seat 3 and the rotating seat 2, making the bracket structure more compact.

[0034] In the preferred embodiment, a first mounting groove 22 is provided at the top of the rotating seat 2, a second mounting groove 33 is provided on the inner side of the top of the accommodating cavity 31, and the top and bottom of the spring 4 are respectively provided in the second mounting groove 33 and the first mounting groove 22.

[0035] In the preferred embodiment, a bearing 23 is provided at the bottom of the rotating seat 2, and an annular groove 11 is provided at the top of the fixed seat 1. The bearing 23 is movably arranged in the annular groove 11. The bearing 23 can reduce the friction between the rotating seat 2 and the fixed seat 1, so that the user can rotate the seat more smoothly.

[0036] In a preferred embodiment, a mounting hole 24 is provided on the rotating seat 2, a through hole 12 is provided on the fixed seat 1, and the mounting hole 24 and the through hole 12 are connected by rivets.

[0037] In the preferred embodiment, it also includes at least three supporting legs 5, and at least three first joints 13 are evenly arranged around the outer edge of the fixed seat 1. The supporting legs 5 are rotatably connected to the first joints 13. By folding and unfolding the supporting legs 5, the use state of the seat can be switched, which is convenient for storage.

[0038] In the preferred embodiment, at least three support tubes 6 are further included. At least three second joints 34 are evenly arranged around the outer edge of the connecting seat 3. The support tubes 6 are rotatably connected to the second joints 34. Oxford cloth is mounted on the support tubes 6 to support the user. By folding and unfolding the support tubes 6, the use state of the seat can be switched, which is convenient for storage.
