Pull rings 10 for facilitating the movement of the folded basketball stand are respectively installed on the left and right side walls of the front end of the base 1; the lower end of the rear support frame 3 is hinged to the rear end of the base 1 through a first pin shaft 11, and the upper end of the rear support frame 3 is hinged to the lower end of the column 4 through a hinge 24. A column expansion angle positioning mechanism is provided between the rear support frame 3 and the column 4, and the column expansion angle positioning mechanism can make the column 4 just upright when it is flipped upward and expanded to the extreme position relative to the rear support frame 3. In this embodiment, the structure of the column expansion angle positioning mechanism includes: the rear support frame 3 is a square tube with a hollow interior and an open upper end, and the column 4 is also a square tube, and the outer wall of the rear side plate 400 at the lower end of the column 4 is hingedly connected to the outer wall of the rear side plate 300 at the upper end of the rear support frame 3 by a hinge 24, and a positioning plate 25 is fixed to the lower end of the column 4 in front of the hinge 24. When the column 4 is turned upward and expanded relative to the rear support frame 3, the positioning plate 25 will be turned into the rear support frame 3 from the open upper end of the rear support frame, and when the positioning plate 25 is turned into the rear support frame 3 and pressed backward against the inner wall of the rear side plate 300 of the rear support frame, the column 4 is just turned upward and expanded to an upright shape relative to the rear support frame 3. The above-mentioned column expansion angle positioning mechanism is positioned by cooperating with the positioning plate and the square tube-shaped rear support frame, the structure is simple, and due to the small number of components, it is easy to install and maintain;

[0027] The backboard 7 is connected to the column 4 through a parallel four-bar linkage structure, and the backboard 7 is always kept parallel to the column 4 through the parallel four-bar linkage structure. The parallel four-bar linkage structure includes: an upper pull rod 13 and a lower pull rod 14 arranged in parallel, one end of the upper pull rod 13 is hinged to the backboard 7 through a third pin 15, and the other end of the upper pull rod 13 is hinged to the column 4 through a fourth pin 16, one end of the lower pull rod 14 is hinged to the backboard 7 through a fifth pin 17, and the other end of the lower pull rod 14 is hinged to the column 4 through a sixth pin 18. The backboard 7, the upper pull rod 13, the lower pull rod 14 and the column 4 together constitute a parallel four-bar linkage structure; an energy band is provided between the backboard 7 and the column 4. The pneumatic assembly for the dynamic backboard 7 to be moved forward and expanded relative to the upright post 4 or moved backward and retracted onto the upright post 4 comprises: a gas spring 19 arranged between the backboard 7 and the upright post 4, one end of the gas spring 19 being hinged to the upper end of the backboard 7 via a seventh pin 20, and the other end of the gas spring 19 being hinged to the lower end of the upright post 4 via an eighth pin 21. The gas spring 19 has only two use states: a piston rod extension state and a piston rod shortened state. When the piston rod of the gas spring 19 is in the extension state, the gas spring 19 will pull the backboard 7 to move backward relative to the upright post 4 and retract onto the upright post 4. When the piston rod of the gas spring 19 is in the shortened state, the gas spring 19 will push the backboard 7 to move forward and expand relative to the upright post 4.

[0028] The front side of the sheath bracket 2 is covered with a sheath plate 22. The lower end of the sheath bracket 2 is hinged to the front end of the base 1 through a ninth pin 23. The upper end of the sheath bracket 2 can be connected and fixed to the upright column 4 that is unfolded through a connecting mechanism to put the basketball stand in an unfolded state. The counterweight 5 is used to be placed on the base 1 of the basketball stand in the unfolded state. The counterweight 5 is a plurality of counterweight buckets. In this embodiment, the number of counterweight buckets is four, and the four counterweight buckets are evenly distributed on the base 1. In this embodiment, the structure of the connecting mechanism includes: two symmetrical mounting ear plates 26 are fixed to the upper end of the sheath bracket 2, the two mounting ear plates 26 are distributed on both sides of the column 4, the gap between the two mounting ear plates 26 constitutes a positioning hole 27 for facilitating the insertion of the column 4, a pair of first mounting holes 28 are symmetrically provided on the two mounting ear plates 26, and a second mounting hole 29 is provided at the lower end of the column 4 that passes through the column 4. The column 4 that is flipped upward relative to the rear support frame 3 and unfolded to an upright shape is snapped into the two mounting plates of the sheath bracket. When the positioning opening 27 formed by the ear plate 26 is formed, the first mounting holes 28 of the two mounting ear plates 26 of the sheath bracket just correspond to the second mounting holes 29 of the column 4 at the same time, and a locking bolt 30 is passed through the corresponding first mounting hole 28 and the second mounting hole 29. The screw of the locking bolt 30 passes through the first mounting hole 28 of one mounting ear plate 26, the second mounting hole 29 of the column 4 and the first mounting hole 28 of the other mounting ear plate 26 in sequence and is threadedly connected with a locking nut 31, thereby securing the sheath bracket. The frame 2 is connected and fixed to the column 4; when the basketball stand needs to be folded, it is only necessary to loosen and remove the locking nut 31, and then pull the locking bolt 30 out of the first mounting hole 28 and the second mounting hole 29. At this time, the sheath bracket 2 is separated from the column 4. At this time, the sheath bracket 2 can be freely turned around the ninth pin 23 relative to the base 1, and the column 4 can be freely turned around the hinge 24 relative to the rear support frame 3. At the same time, the rear support frame 3 can also be freely turned around the first pin 11 relative to the base 1, so that the basketball stand can be folded and retracted;

[0029] When the basketball stand needs to be unfolded for use, the upright column 4 is first flipped upward relative to the rear support frame 3 around the hinge 24 and unfolded. During the process of flipping the upright column 4 upward relative to the rear support frame 3, the positioning plate 25 at the bottom of the upright column 4 will flip into the rear support frame 3 from the upper opening of the rear support frame. When the positioning plate 25 flips into the rear support frame 3 and presses backward against the inner wall of the rear side plate 300 of the rear support frame, the upright column 4 is just flipped upward relative to the rear support frame 3 and unfolded into an upright position. Then, keeping the upright column 4 in an upright position, the upright column 4 is snapped into the positioning hole 27 formed by the two mounting ear plates 26 of the guard bracket 2 with the flip angle adjusted. Then, the screw of the locking bolt 30 is passed through the first mounting hole 28 of one mounting ear plate 26, the second mounting hole 29 of the upright column 4 and the first mounting hole 28 of the other mounting ear plate 26 in sequence, and then the locking nut 31 is tightened, so that the guard bracket is fixed by the locking bolt 30 and the locking nut 31. The sleeve bracket 2 is fixed to the column 4. At this time, the sleeve bracket 2 and the column 4 fixed together will form a stable triangular structure with the rear support frame 3 and the base 1. Then the backboard 7 is pulled forward, so that the gas spring 19 is in a shortened state that gradually tilts forward from the bottom to the top. In the process of the gas spring 19 adjusting from the extended state to the shortened state that gradually tilts forward from the bottom to the top, the gas spring 19 will push the backboard 7 forward relative to the column 4 and expand. Since the backboard 7 is connected to the column 4 through a four-bar structure, the backboard 7 and the column 4 will always be parallel. Since the column 4 is upright at this time, the backboard 7 also always remains upright at this time. When the piston rod of the gas spring 19 is in a shortened state, the backboard 7 and the basket ring 6 are in an expanded state that can be used by children. Then the four counterweight buckets are evenly placed on the base 1. At this time, the basketball stand as a whole is in an expanded and usable state that can be used by children.

[0030] When the basketball stand needs to be stored, it is only necessary to loosen and remove the locking nut 31, and then pull the locking bolt 30 out of the first mounting hole 28 and the second mounting hole 29. At this time, the sheath bracket 2 is separated from the column 4. At this time, the sheath bracket 2 can be freely flipped relative to the base 1 around the ninth pin 23, and the column 4 can be freely flipped relative to the rear support frame 3 around the hinge 24. At the same time, the rear support frame 3 can also be freely flipped relative to the base 1 around the first pin 11, so that the basketball stand can be folded and retracted; then, the sheath bracket 2 is first flipped backward and downward around the ninth pin 23, folded and retracted to the base 1, and then the rear support frame 3 is flipped forward and downward around the first pin 11, folded and retracted. The sheath bracket 2, then the column 4 is flipped backward and downward around the hinge 24, folded and stored in the rear support frame 3, and then a force is applied to the backboard 7 toward the column 4, so that the gas spring 19 is in an extended state that is gradually tilted downward and backward, so that the backboard 7 is folded and stored relative to the column 4, thereby completing the folding of the basketball stand. The basketball stand in the folded state occupies a small space, so it occupies a small transportation space during transportation and a small storage space during storage. When the basketball stand is in the folded state, the front end of the basketball stand can be lifted by the pull ring 10, so that the basketball stand as a whole can touch the ground through the rear wheels 8, and the basketball stand can be conveniently moved at this time.

[0031] The advantages of the present invention are: (1) the basketball stand can be folded, and the basketball stand in the folded state occupies little space, so it takes up little space during transportation and little space during storage. Moreover, when the basketball stand is in the folded state, the front end of the basketball stand can be lifted by the pull ring so that the entire basketball stand can touch the ground through the rear wheels, and the basketball stand can be easily moved at this time; (2) the basketball stand has a simple structure and is very convenient to unfold and assemble.

[0032] The above description is only a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any modification or equivalent change made based on the technical essence of the present invention shall still fall within the scope of protection required by the present invention.
