Description

Technical Field

[0001] This application relates to the field of basketball hoop technology, specifically a triangular basketball hoop with high stability. Background Technology

[0002] Basketball hoops are essential equipment for basketball courts. Basketball equipment, including backboards and backboard supports, is installed in the center of both ends of the basketball court.

[0003] Existing patent (publication number: CN207871438U) discloses a basketball hoop, including a backboard, a rim, and a support frame for supporting the backboard. The support frame has a rotating device, which includes a pivot shaft whose center line passes through the center of the rim. This invention, by designing a rotating device, drives the backboard to rotate by rotating the support frame, while maintaining the rim's center position during rotation, only adjusting the backboard's orientation, allowing users to practice shooting from different angles. Furthermore, it incorporates as many positioning structures as possible, allowing the support frame to rotate at more angles and then fixing its position after rotation.

[0004] The aforementioned basketball hoop rotates the backboard by rotating the support frame, while keeping the center position of the basket unchanged during rotation, only adjusting the orientation of the backboard to facilitate users practicing shooting from different angles. It incorporates as many positioning structures as possible to allow the support frame to rotate at more angles and fix its position after rotation. However, during use, the backboard is continuously subjected to the impact of the basketball, and after prolonged use, the backboard and rotating support frame are prone to deformation and bending, ultimately affecting shooting accuracy and the equipment's lifespan. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a highly stable triangular basketball hoop, which possesses advantages such as high stability and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a highly stable triangular basketball hoop, comprising a supporting base plate, a bottom basket pole fixedly connected to the upper surface of the supporting base plate, a top basket pole fixedly installed at the top of the bottom basket pole, and a backboard fixedly installed at the top of the top basket pole; Both sides of the supporting base plate are provided with bottom support members, and the top of each of the two bottom support members is provided with an arc-shaped mounting sleeve. The two arc-shaped mounting sleeves are fixedly connected by bolts. The bottom basket rod is located between the two arc-shaped mounting sleeves, and the arc-shaped mounting sleeves of the two bottom support members and the supporting base plate form a triangular structure.

[0007] The top of the bottom basket pole is fixedly connected to a hinge seat, and a top support is provided inside the hinge seat; The upper surface of the support base plate is provided with a sliding groove, and a counterweight assembly is provided on the upper surface of the support base plate.

[0008] Furthermore, the bottom support includes a threaded sleeve, with connecting rods threaded to both ends of the threaded sleeve. The lower connecting rod is hinged to one side of the support base plate, and the uppermost connecting rod is hinged to the arc-shaped mounting sleeve.

[0009] The above solution, through the setting of the threaded sleeve, allows for adjustment of the overall length of the bottom support component, thereby adjusting the supported position according to the total length of the bottom and top basket poles.

[0010] Furthermore, the top support includes an adjusting plate, the bottom end of which is hinged to a hinge seat. An extension sleeve is slidably fitted onto the outer surface of the adjusting plate. Two symmetrically arranged support plates are rotatably connected to the top end of the extension sleeve. A connecting block is hinged to the other end of the two support plates. The connecting block can be fixed to the backboard with bolts. A handle is fixedly connected to the outer surface of the extension sleeve. The extension sleeve can be fixed to the adjusting plate with bolts.

[0011] The above solution, through the connection of the extension sleeve and the adjustment plate, can provide auxiliary support for backboards of different heights. At the same time, the extension sleeve, the support plate and the bottom basket pole form a right-angled triangle structure, and the two support plates and the backboard form a triangular structure. The right-angled triangular support formed by the connection of the extension sleeve and the adjustment plate, together with the double triangular structure formed by the support plate and the backboard, decomposes the vertical impact load into axial pressure and lateral shear force, effectively preventing backboard deformation.

[0012] Furthermore, the counterweight assembly includes a lead screw and an L-shaped plate. The two ends of the lead screw are rotatably connected to the two inner sidewalls of the slide groove. A movable block is threadedly connected to the outer surface of the lead screw. The movable block is slidably connected to the slide groove. A counterweight is fixedly connected to the upper surface of the movable block. The L-shaped plate is fixedly connected to the upper surface of the support base plate. A drive shaft is rotatably connected to the upper surface of the L-shaped plate. A rocker arm is fixedly connected to the top end of the drive shaft. A bevel gear is installed at the bottom end of the drive shaft and one end of the lead screw. The two bevel gears are meshed together.

[0013] The above scheme allows the rocker arm to be turned, which in turn drives the lead screw to rotate, thereby moving the counterweight away from the backboard and improving the anti-overturning force.

[0014] Furthermore, a set of mounting slots are provided at the bottom of the support base plate, and a self-braking wheel is installed inside each mounting slot.

[0015] The above solution, through the embedded installation design of the self-braking wheel, preserves the mobility for rapid deployment of the equipment.

[0016] Furthermore, the connection between the top and bottom basket poles is detachable.

[0017] With the above solution, the connection between the two is fixed by bolts, and the top basket poles of different lengths can be replaced, thus making it suitable for the standard basket height.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects: This highly stable triangular basketball hoop utilizes a triangular mechanical structure formed by a bottom support and an arc-shaped mounting sleeve, combined with a double triangular support structure created by an adjustable top support. This effectively transmits the impact force received by the backboard. The bottom triangular structure, through rigid connection, disperses vertical loads and horizontal impact forces to the support base plate, preventing concentrated stress at the base of the basket. The right-angled triangular support formed by the top support plate and the adjustment plate decomposes the shooting impact load into axial pressure and lateral shear force. Combined with the secondary triangular reinforcement formed by the support plate and the backboard, it achieves multi-directional decomposition and balanced bearing of impact forces. The lateral displacement adjustment function of the counterweight components can adjust the overall center of gravity distribution, significantly improving anti-overturning performance. Through the multi-level triangular structure linkage, it solves the deformation problem caused by single-point stress in traditional basketball hoops, effectively improving impact resistance and long-term stability while ensuring structural lightweighting.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1 , Figure 4 and Figure 5 This embodiment presents a highly stable triangular basketball hoop, including a supporting base plate 1. A bottom basketball pole 2 is fixedly connected to the upper surface of the supporting base plate 1. A top basketball pole 3 is fixedly installed at the top of the bottom basketball pole 2. A backboard 4 is fixedly installed at the top of the top basketball pole 3. A set of mounting slots 11 are provided at the bottom of the supporting base plate 1. Each mounting slot 11 is equipped with a self-braking wheel 12. The embedded installation design of the self-braking wheel 12 preserves the mobility of the equipment for rapid deployment. The connection between the top basketball pole 3 and the bottom basketball pole is detachable and fixed by bolts. Different lengths of top basketball pole 3 can be replaced, making it suitable for standard basketball hoop heights. The top basketball pole 3 and the bottom basketball pole 2 are specifically made of 7075-T6 aviation aluminum alloy, which achieves overall weight reduction while ensuring a bending strength of ≥450MPa. A single pole can withstand a static torque of 3000N·m.

[0023] Please see Figure 1 , Figure 2 and Figure 3 Both sides of the supporting base plate 1 are provided with bottom support members 5. The top of each bottom support member 5 is provided with an arc-shaped mounting sleeve 6. The bottom support member 5 includes a threaded sleeve 501. Both ends of the threaded sleeve 501 are threadedly connected to connecting rods 502. The lower connecting rod 502 is hinged to one side of the supporting base plate 1, and the uppermost connecting rod 502 is hinged to the arc-shaped mounting sleeve 6. Through the setting of the threaded sleeve 501, the overall length of the bottom support member 5 can be adjusted, and the supported position can be adjusted according to the total length of the bottom basket pole 2 and the top basket pole 3. The two arc-shaped mounting sleeves 6 are fixedly connected by bolts. The bottom basket pole 2 is located between the two arc-shaped mounting sleeves 6. The two bottom support members 5, the arc-shaped mounting sleeves 6 and the supporting base plate 1 form a triangular structure. Through the above settings, the bottom support members 5, the arc-shaped mounting sleeves 6 and the base plate form a stable triangular mechanical structure, effectively dispersing vertical load and horizontal impact force, and preventing the base of the basket pole from deforming or tilting due to long-term stress.

[0024] Please see Figure 1 , Figure 2 and Figure 3The bottom basket pole 2 is fixedly connected to a hinge seat 7. A top support member 8 is installed inside the hinge seat 7. The top support member 8 provides multi-directional mechanical support for the backboard 4. The shooting impact force is transmitted to the bottom basket pole 2 through the triangular support structure of the support plate 803 and the adjustment plate 801, preventing bending or loosening of the connection due to single-point force on the backboard 4. The top support member 8 includes an adjustment plate 801. The bottom end of the adjustment plate 801 is hinged to the hinge seat 7. An extension sleeve 802 is slidably fitted onto the outer surface of the adjustment plate 801. Two symmetrically arranged support plates 803 are rotatably connected to the top end of the extension sleeve 802. A connecting block 804 is hinged to the other end of the two support plates 803. The extension sleeve 802 can be fixed to the backboard 4 with bolts. The outer surface of the extension sleeve 802 is fixedly connected with a handle 805. The extension sleeve 802 can be fixed to the adjusting plate 801 with bolts. Through the sleeve connection between the extension sleeve 802 and the adjusting plate 801, the backboard 4 at different heights can be provided with auxiliary support. At the same time, the extension sleeve 802, the support plate 803 and the bottom basket 2 form a right-angled triangle structure. The two support plates 803 and the backboard 4 form a triangular structure. The sleeve connection between the extension sleeve 802 and the adjusting plate 801 forms a right-angled triangular support. Combined with the double triangular structure formed by the support plate 803 and the backboard 4, the vertical impact load is decomposed into axial pressure and lateral shear force, effectively preventing the backboard 4 from deforming.

[0025] Please see Figure 1 , Figure 4 and Figure 5 The upper surface of the support base plate 1 is provided with a sliding groove 9, and a counterweight assembly 10 is provided on the upper surface of the support base plate 1. After installation, the overall center of gravity position can be optimized by adjusting the lateral displacement of the counterweight assembly 10. The counterweight assembly 10 includes a lead screw 101 and an L-shaped plate 102. The two ends of the lead screw 101 are rotatably connected to the two inner side walls of the sliding groove 9. A moving block 103 is threadedly connected to the outer surface of the lead screw 101. The moving block 103 is slidably connected to the sliding groove 9. The upper surface of the moving block 103 is fixedly connected to... The counterweight 104 and the L-shaped plate 102 are fixedly connected to the upper surface of the support base plate 1. The upper surface of the L-shaped plate 102 is rotatably connected to the drive shaft 105. The top end of the drive shaft 105 is fixedly connected to the rocker arm 106. The bottom end of the drive shaft 105 and one end of the lead screw 101 are both equipped with bevel gears 107. The two bevel gears 107 are meshed together. By rotating the rocker arm 106, the lead screw 101 can be driven to rotate, thereby driving the counterweight 104 to move away from the backboard 4, thereby improving the anti-overturning force.

[0026] The working principle of the above embodiment is as follows: When the basketball hoop is assembled, the bottom support members 5 on both sides are rigidly connected to the bottom basket pole 2 through the arc-shaped mounting sleeve 6. The lower end of the bottom support member 5 is hinged to the support base plate 1, and the upper end is clamped and fixed to the basket pole through the arc-shaped mounting sleeve 6, forming a stable triangular structure. This structure transmits the impact load and horizontal thrust borne by the backboard 4 to the support base plate 1 through a rigid connection, avoiding the risk of deformation or tilting caused by stress concentration at the base of the basket pole in the traditional single-pole support structure. The adjustment plate 801 of the top support member 8 and the extension sleeve 802 form a right-angled triangular support through the sleeve structure. When the backboard 4 is impacted by a shot, the impact force is first transmitted to the extension sleeve 802 through the support plate 803, and then converted into axial pressure and lateral shear force through the right-angled triangular structure. At the same time, the support plate 803 and the back plate of the backboard 4 form a triangular reinforcement structure, further decomposing the impact force into oblique components. Through multi-directional transmission, the single-point force on the backboard 4 is avoided. If the bending or loosening of the connecting parts occurs, the rocker arm 106 drives the bevel gear 107 to rotate, which in turn drives the lead screw 101 to rotate, causing the moving block 103 to move laterally along the slide groove 9. This, in turn, pushes the counterweight block 104 to move away from the backboard 4. The anti-overturning torque generated by the counterweight block 104 can effectively counteract the overturning caused by external forces, significantly improving overall stability. The bottom support 5 adjusts the length of the connecting rod 502 through the threaded sleeve 501, which can adjust the support position according to the height change of the top basket pole 3, ensuring that the triangular frame always maintains the best stress state. The extension sleeve 802 of the top support 8 can slide axially along the adjustment plate 801 to adapt to the installation requirements of backboards 4 of different heights, while maintaining the right-angled triangular support structure. The self-braking wheel 12 is embedded in the support base plate 1. When the equipment is deployed, the position can be locked by the braking mechanism to ensure the stability of use. When it needs to be moved, the brake can be released to achieve rapid movement, taking into account both the fixed requirements of professional basketball hoops and the mobility characteristics of portable equipment.
