[0003] A height-adjustable basketball stand is disclosed in Chinese Patent No. CN207694205U, which includes a support base and a backboard coupled to the support base. The two ends of a short connecting rod are respectively hinged to the backboard and the support base. One end of a long connecting rod is hinged to the backboard, and the middle part of the long connecting rod is hinged to the support base. The other end of the long connecting rod is movably coupled to an adjusting device. The long connecting rod and the short connecting rod are arranged in parallel and spaced apart. The length of the long connecting rod and the short connecting rod between the respective two hinged points is equal. The backboard is raised or lowered by operating the adjusting device through the long connecting rod.

[0004] For the related technology in the above, in the prior art, the worker uses the plug-in cooperation of the locking pin and the plug rod to limit the vertical freedom degree of the sleeve pipe, so as to achieve the effect of locking the height of the backboard. However, this requires the worker to slide the locking pin out of the sleeve pipe and exert force to pull down the connecting seat. Therefore, the worker needs to overcome the gravity of the entire backboard when exerting force, and it is particularly laborious to pull the connecting seat, which brings inconvenience to adjusting the height of the backboard. SUMMARY

[0005] In order to facilitate the adjustment of the height of the backboard, the present application provides a height-adjustable basketball stand.

[0006] The height-adjustable basketball stand provided by the present application adopts the following technical solution:

[0007] A height-adjustable basketball stand includes a support base, a support column, and a backboard. The support column is connected to the support base, and the backboard is arranged on the support column. The support column is provided with a connecting assembly for maintaining the vertical state of the backboard and a height-adjusting assembly for adjusting the height of the backboard. The connecting assembly is connected to the backboard. The height-adjusting assembly includes an adjusting cylinder, an adjusting rod, and a rotating handle. The adjusting rod is rotationally connected to the support column. The adjusting cylinder is rotationally connected to the connecting assembly. The adjusting rod is plug-in cooperated in the adjusting cylinder. The rotating handle is rotationally connected to the adjusting cylinder and screw-threadedly cooperated with the adjusting rod.

[0008] By adopting the technical scheme, when the height of the backboard is adjusted, the worker rotates the rotating handle, the adjusting rod is connected with the supporting column, the adjusting cylinder is moved, the connecting assembly is moved, and the height of the backboard is adjusted. The worker adjusts the height of the backboard by rotating the rotating handle, the friction between the rotating handle and the adjusting rod overcomes the gravity of the backboard, the worker does not need to bear the gravity from the backboard, and rotating the rotating handle becomes more labor-saving, so that the height of the backboard is adjusted more conveniently.

[0009] Optionally, the supporting column is inclined, the supporting seat is provided with an auxiliary supporting plate for supporting the supporting column, the connecting assembly comprises a first frame, a second frame, a third frame and a mounting plate, the third frame is vertically connected to the supporting column, the first frame is rotationally connected to the lower end of the third frame, the second frame is rotationally connected to the upper end of the third frame, the first frame is parallel to the second frame, the mounting plate is also vertically arranged and rotationally connected between the first frame and the second frame, the adjusting cylinder is rotationally connected to one end of the first frame away from the mounting plate, and the backboard is detachably connected to the mounting plate.

[0010] By adopting the technical scheme, compared with the vertical supporting column, the inclined supporting column is matched with the auxiliary supporting plate, the connection strength between the supporting column and the supporting seat is further improved, and the load capacity of the supporting column is improved; the lower the height is, the farther the relative distance between the supporting column and the backboard is, which is a safety distance; thus, after sprinting and shooting, the athlete moves a small distance due to inertia, the athlete does not collide with the supporting column at the first time due to the safety distance, the athlete is provided with reaction time, and the possibility of injury of the athlete is reduced. The adjusting cylinder is lowered, the first frame is rotated clockwise, the second frame is also rotated clockwise, the third frame is stationary and vertically arranged, the mounting plate is kept in a vertical state during movement, and the backboard is also kept in a vertical state.

[0011] Optionally, a mounting assembly is arranged between the mounting plate and the backboard, the mounting assembly comprises a mounting frame, a plug-in plate, a locking block and an ejection spring, the mounting frame is connected to the mounting plate, one end of the plug-in plate is connected to the backboard, the other end of the plug-in plate is plug-in matched in the mounting frame, a sliding groove is formed in the plug-in plate, the locking block is slidingly matched in the sliding groove, an inclined surface is arranged on the locking block, the ejection spring is arranged in the sliding groove and located between the locking block and the bottom wall of the sliding groove, a locking groove is formed in the mounting frame at a position corresponding to the sliding groove, and the locking block abuts against the inner top wall of the locking groove.

[0012] By adopting the technical scheme, when the backboard is installed, the staff inserts the plug-in plate into the installation frame, the inclined surface abuts against the edge of the installation frame, the locking block enters the sliding groove, the ejecting spring is compressed, until the plug-in plate abuts against the inner groove bottom wall of the installation frame, at this time the locking groove coincides with the sliding groove, the locking block moves under the action of the ejecting spring, and the locking block partially enters the locking groove, the locking block abuts against the inner top wall of the locking groove, thereby limiting the plug-in plate from coming out of the installation frame, and the locking effect of the backboard is achieved.

[0013] Optionally, a buffer pad is arranged in the installation frame and located between the plug-in plate and the installation frame.

[0014] By adopting the technical scheme, when the backboard is used, the backboard will be impacted by the basketball, and the vibration energy will be transmitted to the installation plate through the plug-in plate, so that the support column is vibrated, and with long-time use, the possibility of dislocation and deviation of the various rotating connection parts of the connecting assembly due to the vibration energy exists. The staff utilizes the elastic deformation of the buffer pad to absorb the vibration energy from the backboard to a certain extent, relieves the vibration energy received by the connecting assembly, and prolongs the service life of the connecting assembly.

[0015] Optionally, an auxiliary dismounting assembly is arranged on the installation frame, the auxiliary dismounting assembly comprises rotating pliers, a pushing column and a pressing spring, the rotating pliers are rotatably connected to the installation frame at two ends, the two rotating pliers are oppositely arranged, one end of the rotating pliers extends to a position of the installation frame close to the locking groove, the pushing column is connected to one end of the rotating pliers, and the pressing spring is connected between the other ends of the two rotating pliers.

[0016] By adopting the technical scheme, when the backboard is damaged and needs to be replaced, the locking block is inside the locking groove, which increases the difficulty of dismounting the plug-in plate, and therefore an auxiliary structure for dismounting the plug-in plate is needed. When the backboard is dismounted, the staff presses the other ends of the two rotating pliers to move the other ends of the two rotating pliers towards each other, the pressing spring is compressed, one end of the rotating pliers is close to the locking groove, the pushing column pushes the locking block, until the locking block enters the moving groove, and then the plug-in plate can be removed to dismount the backboard. When the staff releases the rotating pliers, the rotating pliers will be automatically returned to the initial angle position under the action of the pressing spring.

[0017] Optionally, the support column and the auxiliary support plate are rotatably connected to the support seat, an angle adjusting assembly is arranged on the support column, the angle adjusting assembly comprises a rotating rod and a rotating ball, the support column is provided with a containing groove at a position corresponding to the auxiliary support plate, the rotating ball is connected in the containing groove, the rotating rod passes through the rotating ball and the auxiliary support plate, the rotating rod is threadedly connected to the auxiliary support plate and rotatably connected to the rotating ball, and a locking piece for locking the rotating rod on the auxiliary support plate is arranged on the rotating rod.

[0018] By adopting the technical scheme, when installing the basketball stand, in order to ensure the vertical accuracy of the backboard and provide a better experience for the players when shooting, the inclination angle of the support column needs to be finely adjusted. When adjusting the angle of the backboard, the worker rotates the rotating rod, so that the distance between the auxiliary support plate and the support column changes, the angle between the ball and the rotating rod also changes, and the angle of the support column also changes, until the backboard reaches the vertical state, and then the rotating rod is locked by the locking piece, so that the effect of adjusting the angle of the backboard is achieved.

[0019] Optionally, the locking piece is a locking nut, and the locking piece abuts against the auxiliary support plate.

[0020] By adopting the technical scheme, when locking the rotating rod, the worker rotates the locking piece, so that the locking piece moves on the rotating rod until the locking piece abuts against the auxiliary support plate, so as to increase the friction between the rotating rod and the auxiliary support plate, thereby limiting the rotation of the rotating rod.

[0021] Optionally, a fixing rod is connected to the second frame, a buffer spring is connected between the fixing rod and the mounting plate, and the height of the top end of the support column is higher than the height of the top end of the third frame.

[0022] By adopting the technical scheme, with the long-term use of the basketball stand, the connecting assembly is continuously affected by the vibration energy, and the third frame may be separated from the support column. Since the first frame is rotationally connected to the support column, at this time the backboard and the second frame will be turned over and fall off, and the backboard has a safety hazard. The spring is used to pull the second frame, so that the third frame rotates (if the third frame is separated from the support column), and the top end of the third frame is quickly abutted against the support column, so as to stop the turning over of the backboard, and the possibility of occurrence of the safety hazard of the backboard is reduced.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. When adjusting the height of the backboard, the worker rotates the rotating handle, and since the adjusting rod is connected to the support column, the adjusting cylinder moves, driving the connecting assembly to move, so as to adjust the height of the backboard. The worker adjusts the height of the backboard by rotating the rotating handle, and the friction between the rotating handle and the adjusting rod overcomes the gravity of the backboard, so that the worker does not need to bear the gravity of the backboard, and rotating the rotating handle becomes more labor-saving, so that adjusting the height of the backboard is more convenient.

[0025] 2. When installing the backboard, the worker inserts the insertion plate into the installation frame, the inclined surface abuts against the edge of the installation frame, the locking block enters the sliding groove, the ejection spring is compressed, until the insertion plate abuts against the inner groove bottom wall of the installation frame, at this time the locking groove and the sliding groove coincide, the locking block moves under the action of the ejection spring, and the locking block partially enters the locking groove, the locking block abuts against the inner top wall of the locking groove, thereby limiting the insertion plate from coming out of the installation frame, and the locking effect of the backboard is achieved;
