In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The portable adjustable basketball stand comprises a support rod 1, a base 2, a backboard 3, a first support 4, a second support 5, a fixing plate 12 and an adjusting device; the lower end of the supporting rod 1 is fixed on the base 2; one end of the first bracket 4 is hinged with the support rod 1, and the hinged point is a third hinged point 8; the other end of the first bracket 4 is hinged with the backboard 3, and the hinged point is a first hinged point 6; the second bracket 5 is positioned below the first bracket 4, one end of the second bracket 5 is hinged with the support rod 1, the hinged point is a fourth hinged point 9, the other end of the second bracket 5 is hinged with the backboard 3, and the hinged point is a second hinged point 7; the fixing plate 12 is fixed below the second bracket 5 on the supporting rod 1; one end of the adjusting device is hinged with the fixing plate 12, and the other end is hinged with the outward extending end of the fourth hinge point 9 on the second bracket 5.

The first hinge point 6, the second hinge point 7, the fourth hinge point 9 and the third hinge point 8 are sequentially connected to form a parallelogram structure. The parallelogram principle is utilized, so that the basket and the ground can be always kept in a horizontal state and the backboard and the ground can be always kept in a vertical state during height adjustment.

The adjusting device comprises a connecting rod 10, an inner tube 13 and a crank 14; the upper end of the connecting rod 10 is hinged with the outward extending end of a fourth hinge point 9 on the second bracket 5, and a sleeve 11 is sleeved outside the lower end of the connecting rod 10; the sleeve 11 is hinged with the fixing plate 12; the upper end of the inner pipe 13 sequentially penetrates through the common end of the sleeve 11 and the connecting rod 10, and the inner pipe 13 is in threaded connection with a threaded hole 15 at the lower end of the connecting rod 10 through an external thread structure; the inner pipe 13 is connected with the sleeve 11 through a bearing; the crank 14 is provided at the outer end of the inner tube 13.

A clamping block 16 is arranged outside the bearing. Is used for installing the bearing and plays a role in limiting the bearing.

The inner end of the inner pipe 13 is provided with a baffle ring. The inner pipe 13 is prevented from being separated from the connection pipe 10.

And a reinforcing rib is arranged between the support rod 1 and the base 2. The stability of the whole structure is improved.
