The support leg also includes a locking assembly, which includes a plurality of locking slots spaced apart along the axial direction of the lifting rod, a button seat disposed on the support leg, and a locking button pivotally connected to the button seat in the middle. One end of the locking button has a locking part, and the other end of the locking button is an unlocking end. The locking part passes into the support leg and engages with the corresponding locking slot. When the unlocking end is pressed, the locking part is released from the corresponding locking slot.

[0007] Furthermore, the button base is provided with a cavity extending axially along the support leg and used to accommodate the locking button. The locking button is pivotally connected to the cavity in the middle in the vertical direction. The locking part is located at the lower end of the locking button. A first through hole is provided on the bottom wall of the cavity. A second through hole is provided on the outer periphery of the support leg at the position corresponding to the first through hole. The first through hole and the second through hole form a channel for the locking part to pass into the support leg.

[0008] Furthermore, the engaging assembly also includes a compression spring. The upper end of the engaging button has a first protrusion protruding outward. The first protrusion and the engaging part are located on the same side of the engaging button. The bottom wall of the cavity has a groove at the position corresponding to the first protrusion. The bottom wall of the groove has a second protrusion protruding outward. The two ends of the compression spring are respectively sleeved on the first protrusion and the second protrusion. The compression spring is located between the bottom wall of the groove and the engaging button.

[0009] Furthermore, the button base is provided with a through hole for the support leg to pass through. The through hole has an opening along its axial direction, and clamping parts extend outward from both ends of the opening of the through hole. Fasteners are transversely inserted on the two clamping parts so that the button base is clamped to the support leg.

[0010] Furthermore, the button base is located at the bottom end of the support leg.

[0011] Furthermore, the bottom end of the lifting rod is fitted with an anti-slip sleeve.

[0012] Furthermore, both the support leg and the lifting rod are square tubes.

[0013] A lounge chair includes a seat and a folding frame. The folding frame includes left and right frames arranged symmetrically. The left frame includes a left front leg and a left rear leg, and the right frame includes a right front leg and a right rear leg. Each leg is an adjustable height support leg as described above.

[0014] Furthermore, each chair leg is fixedly fitted with a connecting seat. A first reinforcing rod is fixedly connected between the connecting seats on the left and right front chair legs, and a second reinforcing rod is fixedly connected between the connecting seats on the left and right rear chair legs. The button seats on the left and right front chair legs are respectively connected to the first reinforcing rod through connecting rods, and the button seats on the left and right rear chair legs are respectively connected to the second reinforcing rod through connecting rods.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] First, it is easy to operate: simply press the unlock end of the locking button to release the locking button from the slot, push the lifting rod to the appropriate height, release the button, and then pull the lifting rod slightly to make the locking part engage with the adjacent slot, thus completing the height adjustment. No tools are required, and the adjustment process is simple and efficient.

[0017] Secondly, it has high stability: the locking part inserts into the support leg and engages with the slot. With the reset force of the compression spring, it ensures a stable engagement and effectively prevents loosening or shaking after adjustment. Attached Figure Description
