The present invention relates to the field of chair technologies, and more particularly, to a multifunctional outdoor leisure rotary chair.
A chair is a kind of daily life furniture, and is a seat with a backrest and armrests. Modern chairs pursue aesthetics and fashion, and some chairs are no longer just used as seats, but make human life more convenient with the combination of science and technology.
The patent No. CN201921135335.9 discloses an armchair, including a support structure, a base structure, a backrest structure, and an armrest structure. The support structure is movably connected to the base structure, the backrest structure is movably connected to the base structure, and the armrest structure has one end movably connected to the support structure and the other end connected to the backrest structure. The armchair further includes a buffer support device arranged on the armrest structure and configured to support the backrest structure. The buffer support device includes a supporting rod, two clamping blocks provided with identical slideways, an elastic member, and two positioning rods respectively arranged in the slideways of the two clamping blocks and configured to stabilize the elastic member. Both ends of the positioning rod are respectively fixedly connected to two side surfaces of the slideway. The elastic member is sleeved on the positioning rod. Both ends of the supporting rod are provided with through holes matching the diameter of the positioning rod. The supporting rod is sleeved on one end of the positioning rod close to the backrest structure through the through holes, and the supporting rod slides on the positioning rod. The elastic member is pressed on a side of the supporting rod away from the backrest structure.
The patent No. CN200720052714.2 discloses a combined chair base structure, including a base supporting column, and a cylindrical cover is arranged on the base supporting column. A concave groove is arranged in the cylindrical cover, and the base supporting column is arranged in the concave groove of the cylindrical cover. Further, an upper cover is arranged at a base central part to which the base supporting column is connected, and the upper cover is made of a plastic material. A mounting hole is arranged at the base central part to which the base supporting column is connected, and the base supporting column is cutting from a metal material. The concave groove at the bottom of the above cylindrical cover is a notch opened on a plane, and a middle part of the base supporting column is provided with a clamping position that protrudes outward.
The armchair in the patent No. CN201921135335.9 solves the problems of a relatively vertical backrest and poor user experience due to that the chair cannot be stable when laid flat. The combined chair base structure in the patent No. CN200720052714.2 has a low cost and solves the problem that electroplating of welding points is not bright enough, which affects the appearance of the chair. However, it cannot solve the problem of a damage to the overall structure of the device caused by inability of bearing the weight as the overall structure is excessively deformed due to the excessive weight, and the problem of affecting packaging and shipping due to the inability of stacking many groups during transportation.
The purpose of the present invention is to provide a multifunctional outdoor leisure rotary chair, so as to address the problems raised in the above background, such as the problem of a damage to the overall structure of the device caused by inability of bearing the weight as the overall structure is excessively deformed due to the excessive weight, and the problem of affecting packaging and shipping due to the inability of stacking many groups during transportation.

An outer end surface of the reinforcing arm is mounted on a lower end surface of the supporting inclined column, and the reinforcing arm is a component made of an alloy material. When a user sits on a seat cushion, the weight of the user above the seat cushion provides the gravity downward to the supporting frame, and a distance between the series member and the fitting member is adjusted by using the telescopic cylinder, so that the overall device has a certain degree of buffering, which improves the comfort of the user. By means of the arranged reinforcing arm, when the overall device sinks, the supporting inclined column will bend downward to fit an upper end surface of the reinforcing arm, so as to avoid a damage to the overall structure of the device caused by inability of bearing the weight as the supporting inclined column is excessively deformed due to the excessive weight.
