[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 and Figure 2As shown, an adjustable seating chair includes: a support member 1, which is U-shaped, consisting of two members spaced apart, with its vertical section serving as legs and its horizontal section as armrests. The top of the horizontal section of the support member 1 is fitted with a soft armrest pad 10 to enhance comfort.

[0022] A fixed support rod 2, a movable support rod 3, and the chair body 4 are provided between the two support members 1.

[0023] The fixed support rod 2 is rotatably connected at both ends to the first vertical sections of the two support members 1; the movable support rod 3 is connected at both ends to the second vertical sections of the two support members 1, and its relative height is adjustable. The lounge chair body 4 is mounted on the fixed support rod 2 and the movable support rod 3, and is fixedly connected to the fixed support rod 2 and abuts against the movable support rod 3. Specifically, the front section of the seat cushion of the lounge chair body 4 is fixedly connected to the fixed support rod 2, and the backrest of the lounge chair body 4 abuts against the movable support rod 3. When the relative height of the movable support rod 3 is different, the abutment position is different, and the seating posture of the lounge chair body 4 is different.

[0024] like Figure 3 As shown, the second vertical section of the support member 1 has a recessed sliding groove 11, and the bottom surface of the sliding groove 11 has a plurality of spaced insertion grooves 5. The plurality of insertion grooves 5 are evenly distributed along the length of the sliding groove 11. Both ends of the movable support rod 3 are provided with sliding blocks 6 that are adapted to the sliding groove 11. The sliding blocks 6 are slidably but non-rotatably fitted in the sliding groove 11, so that the movable support rod 3 can only move up and down, but cannot rotate.

[0025] like Figure 4 and Figure 5 As shown, the movable support rod 3 has a hollow interior forming a sliding mounting cavity, within which a slidable fixed rod 7 is installed. The first end of the fixed rod 7 extends from the end of the movable support rod 3 and engages with the insertion groove 5, while the second end is connected to a spring 8 located inside the sliding mounting cavity. The spring 8 holds the fixed rod 7 within the insertion groove 5; when the fixed rod 7 retracts, the spring 8 is compressed. The first end of the spring 8 is fixedly connected to the end of the fixed rod 7, and the second end is fixedly connected to the interior of the movable support rod 3. In this embodiment, the movable support rod 3 is a circular rod, and the internal sliding mounting cavity is also circular. Correspondingly, the fixed rod 7 is also a circular rod, with a chamfered end for insertion into the insertion groove 5.

[0026] A lever 9 is provided at the second end of the fixed rod 7. The lever 9 extends from a slot in the movable support rod 3 to the outside of the movable support rod 3 for manual operation. Preferably, the lever 9 is positioned towards the side of the movable support rod 3 away from the chair body 4. Simultaneously, the two fixed rods 7 are symmetrically arranged inside the movable support rod 3, and the two levers 9 are spaced apart to allow for one-handed operation. The surface of the lever 9 is provided with an anti-slip pattern to increase friction and prevent slippage during operation.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
