[0002] Nowadays, people pay more and more attention to the physical training of teenagers. Many institutions and schools have sports equipment dedicated to training teenagers. Basketball, as a physical confrontation sport centered on hands and an Olympic Games event, is very popular among many teenagers. When training teenagers in basketball, for teenagers of different ages and heights, if the backboard equipment of the same height is used, they cannot give full play to their sports potential. If a backboard is too high, the athlete may be injured due to excessive force during the movement. If a backboard is too low, it is difficult to achieve the sports effect. Moreover, basketball backboards are relatively large and heavy, and it is impossible to require schools or sports institutions to configure backboards of multiple heights, which not only takes up a large amount of space but also increases the maintenance cost.

[0003] The technical content disclosed in the Chinese patent document (Publication No.: CN205994990U, Patent Name: Basketball Stand with Adjustable Height) is as follows: It includes a basket assembly, a base assembly, a pressure cylinder, a one-way air intake device, an air release valve, and an air pipe. The basket assembly includes a backboard, a basket, a guide rod, and a piston assembly. The piston assembly includes a lifting piston rod and a lifting piston. The upper end of the guide rod is fixedly connected to the back of the backboard, and the upper end of the piston rod is fixedly connected to the back of the backboard. The base assembly includes a base, a guide sleeve, and a lifting cylinder. The lifting cylinder and the piston assembly form a cylinder. The space enclosed by the lower surface of the lifting piston, the cylinder barrel, and the bottom surface of the lifting cylinder is the rodless cavity. The guide sleeve is fixedly connected to the base, and the guide rod and the guide sleeve form a moving pair. The pressure cylinder includes a pressure piston assembly and a pressure cylinder body. The pressure piston assembly includes a pressure piston rod and a pressure piston. The space enclosed by the lower surface of the pressure piston and the cylinder barrel of the pressure cylinder body is the pressure chamber.

One end of the intake compression spring presses the intake ball head, and the other end presses the inner wall of the intake chamber. There is an exhaust conical hole in the exhaust chamber. The small mouth of the exhaust conical hole faces the ventilation chamber, and the large mouth faces the outside air. The spherical surface of the exhaust ball head tightly blocks the exhaust conical hole. One end of the exhaust compression spring presses the exhaust ball head, and the other end presses the inner wall of the exhaust chamber.

[0004] As can be seen from the above implementation, the basketball hoop is provided with a cylinder, and the lifting of the backboard is achieved by inflating and deflating, so as to achieve the purpose of adjustable backboard height, making the basketball hoop applicable to people of different heights. However, during the process of raising and lowering the backboard, the center of gravity of the basketball hoop will change. Therefore, if the center of gravity of the basketball hoop is not adjusted in time after the backboard is raised, the center of gravity of the entire basketball hoop will rise, making the basketball hoop prone to tipping over and causing danger.
