In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. Moreover, the terms "first," "second," and the like are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the utility model described herein are capable of operation in sequences other than those illustrated or described herein.

Referring to the attached drawings in the specification, the utility model provides a folding chair with an adjustable angle, which comprises a first supporting leg 10 and a second supporting leg 20, wherein the middle parts of the first supporting leg and the second supporting leg are hinged. The top of this second supporting legs articulates there is a sliding sleeve 50, sets up in the sliding sleeve and holds up pole 30, holds up the top of pole and articulates with the top of first supporting legs mutually. Therefore, when in use, the hinged parts can be adjusted to proper angles, so that the folding chair can reach the most comfortable state for different users; after the use, each rod piece can be folded to a plane for storage. In this embodiment, first supporting legs and second supporting legs are upper end open-ended U-shaped, compare in separately two supporting legs that set up, the structure of U-shaped supporting legs is more stable, and the lower extreme holding surface is bigger. Meanwhile, the first supporting leg, the second supporting leg and the handrail are all hollow rods, so that the overall weight of the folding chair is smaller, and the folding chair is convenient to carry.

Furthermore, in order to control the folding angle of the folding chair, a limiting member 60 is arranged on the handrail, and the limiting member can limit the relative position of the sliding sleeve and the handrail. Specifically, this locating part cover is established on the pole of holding up, and sets up the lower extreme at the sliding sleeve, can set up a bolt that is used for fixed locating part position on the locating part, and sliding sleeve and locating part counterbalance are exactly the folding chair and expand the state to maximum angle like this. The user can move the limiting piece on the handrail to adjust the fixed position of the limiting piece, so that the folding angle of the folding chair is adjusted. Of course, the stopper may be a structure such as a damper, a latch, or the like. When the limiting part is a damper, the damper can be arranged at the hinged joint of the sliding sleeve and the second supporting leg so as to control the angle of the sliding sleeve and further control the angle of the folding chair. The limiting part can also be a bolt inserted in the sliding sleeve and the supporting rod, so that the relative position of the sliding sleeve and the supporting rod is limited. Furthermore, the ribs 51 can be added on both sides of the sliding sleeve, so that the sliding sleeve is firmer.

Further, a rest bar 40 is arranged between the two top ends of the first supporting leg, the rest bar is arc-shaped, and the rest bar can also be a hollow bar. The arc leaning rod is more in line with the ergonomics, so that the back of a user can be leaned on the arc leaning rod when the user sits on the arc leaning rod, and the arc leaning rod is more relaxed. Further, the leaning rod is hinged with the top end of the first supporting leg. Therefore, the leaning rod, the holding rod and the first supporting foot are hinged at the same position, and the relative angles of the three rod pieces can be adjusted at the same position. Specifically, the top end of the handrail is provided with a connecting piece 31 matched with the first supporting leg, the connecting piece is U-shaped, and the first supporting leg is arranged in the U-shaped opening. The end of the rest bar is provided with a connecting sheet 41, the top of the first supporting leg, the connecting sheet of the rest bar and the connecting piece of the rest bar are provided with matched holes, and the holes are internally provided with screw rods 32. Thus, the three rods are hinged at the same position. The end of the screw rod is provided with a thread, and the thread is connected with a matched bolt.

When the folding chair is used, as shown in figure 3, the two U-shaped supporting legs are unfolded, the positions of the sliding sleeve and the limiting piece are adjusted to enable the folding chair to be folded into the most comfortable state, and then the leaning rod is adjusted to a proper angle. When the folding is performed after the use, the leaning rod is firstly rotated downwards as shown in fig. 4; the two support legs are then folded together as shown in fig. 5.

Furthermore, the lower ends of the first supporting leg and the second supporting leg are provided with anti-skid members 11. Specifically, the anti-slip piece is a ring sleeve with an opening, the outer part of the ring sleeve is provided with a convex edge, and the anti-slip piece is matched with the lower end rod parts of the first supporting leg and the second supporting leg in a clamping and sleeving manner. Besides the convex edges, convex points and other anti-skidding structures can be arranged on the ring sleeve. When the antiskid performance of the ring sleeve fails, a new ring sleeve can be replaced, and only the clamping sleeve is required to be arranged on the rod part. The arrangement of the anti-slip piece prolongs the service life of the folding chair.

While the foregoing specification illustrates and describes the preferred embodiments of the present invention, it is to be understood that the utility model is not limited to the precise forms disclosed herein and is not to be considered in an exclusive sense, as the utility model may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept as expressed herein, either by the above teachings or the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the utility model as defined by the appended claims.
