Furthermore, the first connecting grooves 2211, the second connecting grooves 2212 and the third connecting groove 2213 respectively have avoiding openings 2211a, 2212a and 2213a close to the cross rod 21 and stop portions 2211b, 2212b and 2213b away from the cross rod 21. The avoiding openings 2211a, 2212a and 2213a are used to avoid the first rotating connecting heads 2221, the second rotating connecting heads 2231 and the third rotating connecting head 2241 when the two lower supporting rods 222 and 223 and the upper supporting rod 224 are folded, and the stop portions 2211b, 2212b and 2213b are used to stop and position the first rotating connecting heads 2221, the second rotating connecting heads 2231 and the third rotating connecting head 2241 when the two lower supporting rods 222 and 223 and the upper supporting rod 224 are unfolded.

[0035] The interior of the connecting seat 221 is provided with a hollow cavity 2214 in communication with the first connecting groove 2211, the second connecting groove 2212 and the third connecting groove 2213, the locking mechanism 225 comprises a locking block 2251 and a locking block spring 2252, the locking block 2251 is movably arranged in the hollow cavity 2214, the outer periphery of the locking block 2251 is formed with three locking portions 2251a, the first rotating connecting head 2221, the second rotating connecting head 2231 and the third rotating connecting head 2241 are respectively provided with a locking groove 2221a, 2231a and 2241a, when the two lower supporting rods 222 and 223 and the upper supporting rod 224 are in the unfolded position, the three locking portions 2251a are respectively clamped into the corresponding locking grooves 2221a, 2231a and 2241a, thereby locking the two lower supporting rods 222 and 223 and the upper supporting rod 224 in the unfolded position, the locking block spring 2252 directly or indirectly acts on the locking block 2251 to make the three locking portions 2251a respectively keep the tendency of clamping into the corresponding locking grooves 2221a, 2231a and 2241a.

[0036] The locking mechanism 225 further comprises an unlocking button 2253, the unlocking button 2253 comprises a rod portion 2254 and a cap portion 2255 arranged as one body, the rod portion 2254 penetrates into the hollow cavity 2214 and is fixedly connected with the locking block 2251, the cap portion 2255 is exposed outside the side of the hollow cavity 2214 away from the cross rod 21 for pressing operation when unlocking, and the side wall of the hollow cavity 2214 away from the cross rod 21 is provided with a through hole 2215 for the rod portion 2254 to penetrate into the hollow cavity 2214, the locking block spring 2252 is sleeved on the rod portion 2254, and one end of the locking block spring 2252 abuts against the cap portion 2255 and the other end abuts against a positioning step portion 2216 in the through hole 2215.

[0037] When it is needed to loosen the locking of the two lower supporting rods 222 and 223 and the upper supporting rod 224 by the locking mechanism 225, only the cap portion 2255 of the unlocking button 2253 needs to be pressed to make the rod portion 2254 move with the locking block 2251 towards the direction close to the cross rod 21, and then the three locking portions 2251a are respectively separated from the corresponding locking grooves 2221a, 2231a and 2241a, at this time, the two lower supporting rods 222 and 223 and the upper supporting rod 224 can be rotated and folded.

[0038] The included angle between the two lower supporting rods 222 and 223 is 120 degrees, and the included angle between the upper supporting rod 224 and the two lower supporting rods 222 and 223 is also 120 degrees.

[0039] The two lower supporting rods 222 and 223 are inclined from top to bottom to the front and rear direction and the left and right direction of the horizontal rod 21 after unfolding, and the inclination angle of the two lower supporting rods to the front and rear direction of the horizontal rod 21 is greater than the inclination angle to the left and right direction of the horizontal rod 21, and the upper supporting rod 224 is in the form of a vertical rod inclined to the left and right direction of the horizontal rod 21 after unfolding. In this way, the supporting stability of the supporting frame 2 after unfolding can be effectively improved.

[0040] The side of the connecting seat 221 facing the horizontal rod 21 is provided with a connecting sleeve part 226, and the end of the horizontal rod 21 is inserted into the connecting sleeve part 226 and fixedly connected thereto by a screw.

[0041] The folding swing chair of the utility model can detach and separate the chair seat 1 and the supporting frame 2, and fold and store the detached and separated chair seat 1 and supporting frame 2 respectively, so as to reduce the storage volume of the folding swing chair, and further facilitate carrying or storage. The folding and storage process of the supporting frame 2 is as follows: first, loosen the locking mechanism 225 in the two foldable supporting units 22, and then synchronously rotate and fold the two lower supporting rods 222 and 223 and the upper supporting rod 224 in the two foldable supporting units 22 towards the horizontal rod 21.

[0042] The above is only a preferred embodiment of the utility model, and cannot limit the scope of the utility model, that is, any simple equivalent changes and modifications made according to the patent application range and the utility model description are still within the scope of the utility model patent.
