(22) The technical solution of the utility model is further expounded below with reference to the embodiments to be better understood. Those skilled in the art can easily appreciate other advantages and effects of the utility model on the basis of the contents in the specification, and can also implement or apply the utility model in other embodiments and make various transformations or changes on the details in the specification on the basis of different viewpoints and applications without deviating from the spirit of the utility model.

Embodiment 1

(23) As shown in FIGS. 1-9, FIG. 11, FIGS. 13-21, this embodiment discloses a crosswise-folding rocking chair which comprises a chair cloth 1 and a chair frame 2, wherein the chair frame 2 includes two back tubes 3, two turnover bases 4, two armrest tubes 5A, four armrest limit sleeves 6A, four bushings 7, four step rivets 8, two base frames 9, and two wear-resistant foot casings 10, wherein the two back tubes 3 are respectively welded to the two turnover bases 4, which are respectively riveted to the two armrest tubes 5A and can axially rotate around the rivets. Each base frame 9 is formed by a bent steel tube having a necked end, and the necked end is inserted into a non-necked end to form a closed polygonal frame. The two base frames 9 are riveted together in an X shape, and the polygonal frames have lower arc segments and upper joint segments. Two bushings 7 are respectively disposed around two sides of each joint segment through the necked end and the non-necked end, two armrest limit sleeves welded to one armrest tube 5A are respectively disposed around the two bushings, two step rivets penetrate through annular limit grooves in the two armrest limit sleeves to fix the two bushings to one base frame, and the armrest limit sleeves drive the armrest tube welded to the armrest limit sleeves to rotate until the armrest tube makes contact with the rivets. A seat cushion and a backrest of the chair cloth are respectively installed on the joint segments of the base frames and the back tubes; and the two wear-resistant foot casings are respectively arranged on the arc segments of the two base frames.

(24) Preferably, the wear-resistant foot casings 10 have openings in a length direction, and the arc segments are embedded into the wear-resistant foot casings 10 via the openings.

(25) Preferably, two sides of the seat cushion of the chair cloth 1 are respectively disposed around the joint segments of the two base frames 9, and the necked ends are inserted into the non-necked ends to be covered with the cloth on two sides of the seat cushion, so that end-to-end joints of the base frames are prevented from exposure.

(26) The back tubes 3 and the turnover bases 4 which are welded together are riveted to the armrest tubes 5A and can axially rotate around the rivets (as shown in FIG. 13). Each base frame 9 is formed by a bent steel tube having a necked end (as shown in FIG. 18), and the necked end is inserted into a non-necked end to form a closed square frame (as shown in FIG. 19). The two base frames 9 assembled together in a cross manner, the two bushings 7 are disposed around the joint segment of each base frame 9 via two joints, and then the two armrest limit sleeves 6A welded to the armrest tube 5A are respectively disposed around the two bushings 7. The seat cushion of the chair cloth 1 wraps the base frames 9, and the necked ends are inserted into the non-necked ends to be covered with the cloth. The four step rivets 8 penetrate through annular limit grooves in the armrest limit sleeves 6A to fix the four bushings 7 to the base frames 9 (as shown in FIG. 16 and FIG. 17), so that the armrest limit sleeves 6A can drive the armrest tubes 5A welded to the armrest limit sleeves 6A to rotate simultaneously until the armrest tubes 5A make contact with the step rivets 8. The two base frames 9 are riveted together in an X shape in such a manner that the arc segments are located below the joint segments. The wear-resistant foot casings 10 are installed on the arc segments to reduce noises and paint scrapes (as shown in FIG. 11). The backrest of the chair cloth 1 is fixed to the back tubes 3 (as shown in FIG. 7).

(27) The operating principle of the rocking chair in this embodiment is as follows:

(28) When the chair needs to be folded: in an unfolded state (as shown in FIG. 7 and FIG. 11), the back tubes 3 are folded to be horizontal first (as shown in FIG. 13). Then the two crossed base frames 9 are folded (as shown in FIG. 14); and finally, the two armrest tubes 5A rotate outwards to drive the back tubes 3 on the armrest tubes 5A and the chair cloth 1 to rotate simultaneously until the armrest tubes make contact with each other after rotating by 180° (as shown in FIG. 8 and FIG. 15).

(29) When the chair needs to be unfolded: in a folded state (as shown in FIG. 8 and FIG. 15), the armrest tubes 5A are rotated upwards by 180° to drive the back tubes 3 on the armrest tubes 5A and parts, located on the back tubes 3, of the chair cloth 1 to rotate simultaneously upwards (as shown in FIG. 14). The two crossed base frames 9 are unfolded to tighten and unfold the seat cushion of the chair cloth 1 (as shown in FIG. 13). At this moment, the armrest limit sleeves 6A on the armrest tubes 5A exactly abut against the step rivets 8 to prevent the armrest tubes 5A from continuously rotating inwards, so that the armrest tubes 5A are perpendicular to the ground; and the back tubes 3 are turned upwards until the turnover bases 4 abut against the armrest tubes 5A and drive the backrest of the chair cloth 1 to be erected (as shown in FIG. 7 and FIG. 11).

Embodiment 2

(30) Different from Embodiment 1, as shown in FIG. 10 and FIG. 12, this embodiment provides a chair frame of another structure, which includes two back tubes 3, two turnover bases 4, two armrest tubes 5B, four armrest fixing bases 6B, two base frames 9, and two wear-resistant foot casings 10, wherein the two back tubes 3 are respectively welded to the two turnover bases 4, which are respectively riveted to the two armrest tubes 5B and can axially rotate around the rivets. Each base frame 9 is formed by a bent steel tube having a necked end, and the necked end is inserted into a non-necked end to form a closed polygonal frame. The two base frames 9 are riveted together in an X shape, and the polygonal frames have lower arc segments and upper joint segments. The armrest fixing bases 6B are respectively arranged on two sides of the necked end and non-necked end of each joint segment, and the two armrest tubes 5B are respectively riveted to the armrest fixing bases 6B on the two joint segments. A seat cushion and a backrest of the chair cloth 1 are respectively installed on the joint segments of the base frames and the back tubes 3; and the two wear-resistant foot casings 10 are respectively arranged on the arc segments of the two base frames 9.

(31) The armrest fixing bases 6B in this embodiment are preferably arranged on external sides of the joint segments of the base frames 9 and are each formed by two symmetrical fins, and installation holes used for riveting the armrest fixing bases 6B to the armrest tubes are formed in the middle of the fins.

(32) The operating principle of the rocking chair in this embodiment is as follows:

(33) When the chair needs to be folded: in an unfolded state (as shown in FIG. 7 and FIG. 12), the back tubes 3 are folded to be horizontal first (as shown in FIG. 13). Then the two crossed base frames 9 are folded (as shown in FIG. 14); and finally, the two armrest tubes 5B rotate outwards to drive the back tubes 3 on the armrest tubes 5B and the chair cloth 1 to rotate simultaneously until the armrest tubes make contact with each other after rotating by 180° (as shown in FIG. 8 and FIG. 15).

(34) When the chair needs to be unfolded: in a folded state (as shown in FIG. 8 and FIG. 15), the armrest tubes 5B are rotated upwards by 180° to drive the back tubes 3 on the armrest tubes 5B and parts, located on the back tubes 3, of the chair cloth 1 to rotate simultaneously upwards (as shown in FIG. 14). The two crossed base frames 9 are unfolded to tighten and unfold the seat cushion of the chair cloth 1 (as shown in FIG. 13). At this moment, the lower ends of the armrest tubes 5B are dragged by the armrest fixing bases 6B, and the middles of the armrest fixing bases 6B abut against the base frames 9 to prevent the armrest tubes 5B from continuously rotating inwards, so that the armrest tubes 5B are perpendicular to the ground; and the back tubes 3 are turned upwards until the turnover bases 4 abut against the armrest tubes 5B and drive the backrest of the chair cloth 1 to be erected (as shown in FIG. 7 and FIG. 12).

(35) The above embodiments are preferred ones of the utility model, and are not intended to limit the protection scope of the utility model. All transformations and improvements achieved by those skilled in the art on the basis of the design conception of the utility model should fall within the protection scope of the utility model.
