[0027] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] See also Figure 1-7 As shown, a rotating folding chair comprises:

[0029] An upper connecting seat 1, wherein the upper connecting seat 1 is provided with a plurality of supporting frames 3, and a seat cloth 4 is supported by the plurality of supporting frames 3;

[0030] A lower connecting seat 2, wherein the lower connecting seat 2 is provided with a plurality of supporting legs 5, and the plurality of supporting legs 5 can be folded to a folded state, or unfolded to a supporting state;

[0031] The upper connecting seat 1 is connected to the lower connecting seat 2 via a rotating structure 6 , and the upper connecting seat 1 can be rotatably arranged along an axis B.

[0032] After adopting the above structure, the swivel folding chair of the utility model has the following advantages compared with the prior art: when in use, the user can unfold the support legs 5 to the supporting state, and support the support legs 5 on the ground, and after the support frame 3 and the seat cloth 4 are set, the user can sit on the seat cloth 4;

[0033] The lower connecting seat 2 is rotatably connected to the upper connecting seat 1 through a rotating structure 6. The direction of the upper connecting seat 1 is adjustable, and the user can easily adjust the direction of the seat without moving the entire chair, which is convenient for quickly adapting to the direction of viewing or communication in different occasions;

[0034] Plus, the swivel feature reduces movement of the chair, helping to reduce wear and tear and extend its life.

[0035] As an improvement of the present invention, the rotating structure 6 includes an annular groove 6.1 and a protruding portion 6.2, wherein the annular groove 6.1 is arranged on the bottom end surface of the upper connecting seat 1 along the circumference of the upper connecting seat 1, and the protruding portion 6.2 is arranged on the upper end surface of the lower connecting seat 2, and the protruding portion 6.2 is loosely matched with the annular groove 6.1. After the above improvement, the annular groove 6.1 and the protruding portion 6.2 form a loose fit to form a ring-guided limiting structure, so that the rotation function of the upper connecting seat 1 is stable and reliable.

[0036] As an improvement of the present invention, the protrusion 6.2 is an annular structure, and the upper connecting seat 1 is supported as a whole by the protrusion 6.2. The protrusion 6.2 is an annular structure, and after the protrusion 6.2 enters the annular groove 6.1, the upper connecting seat 1 can be supported as a whole. The contact surface between the upper connecting seat 1 and the lower connecting seat 2 is only between the protrusion 6.2 and the annular groove 6.1, which reduces the surface contact, reduces the rotation resistance, improves the stability of the rotation function, and improves the user experience.

[0037] As an improvement of the present utility model, a first through hole 1.1 is provided at the center position of the upper connecting seat 1, and a second through hole 2.1 is provided at the center position of the connecting seat. A connecting shaft 7 is passed through the first through hole 1.1 and the second through hole 2.1. A limiting member 7.1 is provided at the lower end of the connecting shaft 7 to form a blocking fit with the bottom end surface of the second through hole 2.1. A threaded hole 7.2 is provided at the upper end of the connecting shaft 7, and a screw 7.3 is connected to the threaded hole 7.2. The head of the screw 7.3 forms a blocking fit with the upper end surface of the first through hole 1.1. After the above improvements, when the upper connecting seat 1 and the lower connecting seat 2 are assembled, the head of the connecting shaft 7 is inserted from the bottom of the second through hole 2.1, and further, the screw 7.3 is inserted from the upper end of the first through hole 1.1 and connected with the threaded hole 7.2 of the head of the connecting shaft 7. The distance between the bottom of the screw 7.3 and the limiter 7.1 is slightly larger than the distance between the upper end face of the first through hole 1.1 and the bottom end face of the second through hole 2.1, so that the upper connecting seat 1 and the lower connecting seat 2 float up and down within a reasonable range (axial limit), and when the upper connecting seat 1 rotates, the screw 7.3 will not be locked with the upper connecting seat 1, resulting in synchronous rotation and disengagement from the threaded hole 7.2, and has the characteristics of stable connection and reliable operation.

[0038] As an improvement of the present invention, the lower ends of the plurality of support frames 3 are respectively hinged to the upper connecting seat 1, and the upper ends of the plurality of support frames 3 are respectively and independently connected to the cloth corners of the seat cloth 4;

[0039] The upper connecting seat 1 is provided with a limiting portion 1.2, and the support frame 3 can be rotated upward until the inner wall abuts against the limiting portion 1.2 to form an inverted "eight"-shaped position state.

[0040] After the above improvement, the upper end of the support frame 3 is connected to the cloth corner of the seat cloth 4, and the support frame 3 is rotated upward to form an inverted "eight" shape position. At this time, the middle area of ​​the seat cloth 4 can be used for the user to sit. When the user sits, the support frame 3 is forced to continue to rotate upward until the inner wall and the limit part 1.2 are against each other, and the support frame 3 can stably and effectively support the seat cloth 4;

[0041] The support frame 3 can also be rotated downward to a folded position, which can further reduce the space occupied by the device and facilitate the user's carrying.

[0042] As an improvement of the present utility model, the lower connecting seat 2 is provided with a receiving groove 2.2 corresponding to each supporting leg 5, and the upper end of the supporting leg 5 is hinged in the receiving groove 2.2, and the supporting leg 5 can be unfolded to the outer wall against the outer side wall of the receiving groove 2.2 to form an "eight"-shaped supporting state. When the supporting leg 5 is unfolded to the "eight"-shaped supporting state, the supporting leg 5 is supported on the ground at this time. When the user sits, the supporting leg 5 is forced to continue to unfold and rotate, and the outer wall of the supporting leg 5 is against the outer wall of the receiving groove 2.2, and the supporting leg 5 can be stably in the supporting state.

[0043] As an improvement of the present invention, the support frame 3 is a telescopic support frame 3. The telescopic support frame 3 can further reduce space occupation, and the telescopic support frame 3 can be provided with a locking structure to lock the length after telescoping.

[0044] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
