[0002] Outdoor camping is a recreational activity and a short-term outdoor lifestyle. Typically, campers bring tents and leave the city to camp in the wild for one or more nights. Camping can be categorized into regular camping, car camping, and RV camping. Outdoor camping chairs, also known as picnic chairs or portable chairs, are designed specifically for outdoor activities. They are designed to allow people to enjoy comfort outdoors, especially during activities such as camping, picnics, fishing, or outdoor barbecues.

[0003] A search revealed that Chinese utility model patent application number CN202022642937.2 discloses an outdoor chair, including a pair of side frames. The pair of side frames are connected by three crossbars located at the head, middle, and tail of the side frames respectively. All three crossbars are fixed to the side frames by bolt assemblies. Each side frame has a pressure plate embedded on its outer surface, which is fixed to the side frame by a first bolt. A frame is fixed to the outer side of each pressure plate. The two ends of the frame are bent to form support legs. An armrest is fixed to the top of the frame. A seat cushion is fixed to the side frames and crossbars. The various components inside this utility model are connected together by bolts. This improves the overall aesthetics of the outdoor chair. At the same time, since the components are not fixed by welding, there is no need to polish the joints of the components, which facilitates the production of the outdoor chair.

[0004] While the existing outdoor chairs can meet basic usage needs, they still have some shortcomings. First, adjusting the backrest angle is cumbersome, reducing their practicality. Second, it is difficult to adjust the armrests, making them less suitable for user needs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a camping chair with an adjustable backrest, in order to address the above-mentioned defects of the prior art. This solves the problem that adjusting the backrest angle of existing outdoor chairs is cumbersome and that it is difficult to adjust the armrests.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An adjustable-back camping chair includes a seat cushion, a support frame fixed to the bottom of the seat cushion, a backrest provided at the top of the seat cushion, armrest frames fixed to both sides of the seat cushion, armrests provided at the top of the armrest frames, and soft padding fixed to the surface of the armrests. A rotating mechanism is provided on the surface of the armrest frames, and the armrest frames are rotatably connected to the armrests through the rotating mechanism. An adjustment mechanism is provided inside the seat cushion, and the seat cushion is rotatably connected to the backrest through the adjustment mechanism.

[0008] Preferably, the rotating mechanism consists of a fixed ball, an arc-shaped block, an arc-shaped groove, a recess, and a telescopic spring. The fixed ball is fixed to the surface at the top of the handrail, and the fixed ball and the handrail rotate in coordination. The surface of the fixed ball is provided with a recess, and the interior of the recess is provided with an arc-shaped block.

[0009] Preferably, the surface of the handrail is provided with an arc-shaped groove, and the arc-shaped groove and the arc-shaped block are interlocked. Each groove is equipped with a telescopic spring, and one end of the telescopic spring is fixed to the surface of the arc-shaped block.

[0010] Preferably, the adjustment mechanism includes a fastening stud, a throttle, a drive gear, a driven gear, and a fixing groove. The surface of the seat cushion is provided with a fixing groove, and the drive gear is provided inside the fixing groove. The drive gear and the fixing groove rotate and cooperate with each other.

[0011] Preferably, a driven gear is provided inside the fixed groove, and the driven gear rotates and engages with the fixed groove. The driven gear meshes with the driving gear, and the surface of the driven gear is fixed to the surface of the backrest.

[0012] Preferably, a throttle is mounted on the surface of the seat cushion, and one end of the throttle penetrates the seat cushion and is fixed to the surface of the drive gear. A fastening stud is threadedly connected to the surface of the top position of the throttle, and one end of the fastening stud penetrates the throttle and is threadedly fastened to the surface of the drive gear.

[0013] By adopting the above technical solution, the camping chair with an adjustable backrest provided by this utility model has the following beneficial effects: 1. By setting an adjustment mechanism, loosening the fastening stud and then turning the handle causes the handle to drive the drive gear to rotate. Under the meshing action of the drive gear and the driven gear, the driven gear rotates inside the fixed groove. Under the action of the driven gear, the backrest rotates. When the backrest is adjusted to the desired angle, tightening the fastening stud fixes the drive gear, thereby fixing the driven gear and the backrest, thus realizing the function of quickly adjusting the backrest angle of the outdoor chair. This improves the practicality of the outdoor chair; 2. By setting up a rotating mechanism, when a person places their arm on the surface of the armrest, the comfort of the armrest is enhanced by the soft padding. Due to different needs, the angle of the armrest can be adjusted to better meet people's needs. When the armrest moves, it rotates on the surface of the fixed ball, and under the elastic force of the telescopic spring inside the groove, it drives the arc-shaped block to move into the corresponding arc-shaped groove, thereby fixing the armrest to the surface of the armrest frame. This realizes the function of adjusting the armrest of the outdoor chair, making the armrest more in line with people's needs. Attached Figure Description
