Description

Technical Field

[0001] This invention relates to the field of basketball hoop technology, and more specifically to a suspended basketball hoop. Background Technology

[0002] Suspended basketball hoops are widely used in indoor venues due to their advantage of not occupying limited floor space. They are classified into manual and electric suspended types based on their operation.

[0003] Patent application number 2023111238736.8 discloses a manually operated suspended basketball hoop. Its structure includes: two sets of suspension rods fixedly installed on the connecting beams of the indoor stadium's roof frame, the two sets of suspension rods being spaced apart in a front-to-back direction; a crossbeam is connected to the lower end of each set of suspension rods, with cable pulleys supported on the front and rear crossbeams respectively; the upper end of the hoop is hinged to the front crossbeam, and a backboard assembly consisting of a backboard and a rim is installed at the lower end of the hoop; a hanging seat is fixed in the middle of the hoop; one end of a steel wire rope is connected to the hanging seat, and the other end passes sequentially around the cable pulleys on the rear and front crossbeams before finally being led out and connected to a hand-cranked self-locking cable winder fixedly installed on the indoor stadium's pillars.

[0004] By tightening the steel cable with a hand-cranked winder, the basketball hoop can be flipped upwards around the hinge point of the front crossbeam to a horizontal, stowed state. When not in use, the entire basketball hoop can be folded into the roof beam, thus reducing space occupation. When in use, the steel cable can be released by the hand-cranked winder, and the basketball hoop will flip downwards under gravity to a vertical use state, at which point the backboard assembly is at the specified standard height.

[0005] However, the aforementioned manually suspended basketball hoops have the following drawbacks: these hoops are only hinged at the top to the front crossbeam and suspended diagonally by steel wire ropes in the middle, with no rigid support structure at the bottom. When the backboard assembly is subjected to external forces in the front-rear direction, the hoops are prone to swaying. This swaying not only reduces the stability of the hoops, interferes with the accuracy of subsequent shots, and affects the user experience, but also exacerbates fatigue wear on key connection points such as the hinge point between the hoops and the crossbeam, thereby reducing the service life and safety reliability of the equipment.

[0006] In addition, a utility model patent with patent application number CN202320684913.4 also discloses an electric suspended basketball hoop. In the structure of this electric suspended basketball hoop, the upper end of the hoop is hinged to a crossbeam located on the front side, and the lower end of the hoop is equipped with a backboard assembly consisting of a backboard and a rim. A folding rod is connected between the lower end of the hoop and the crossbeam behind the hoop. The folding rod includes a U-shaped connecting block, a folding support rod one, and a folding support rod two. One end of the folding support rod one is inserted into the U-shaped connecting block and hinged to one end of the U-shaped connecting block. The other end of the folding support rod one is hinged to the lower end of the hoop. One end of the folding support rod two is inserted into the U-shaped connecting block and hinged to the other end of the U-shaped connecting block. The other end of the folding support rod two is hinged to the crossbeam behind the hoop.

[0007] However, the aforementioned electric suspended basketball hoop has the following drawbacks: The hoop uses a U-shaped connecting block and two folding support rods to form a multi-hinged support structure. The overall structure is a flexible hinged support without a rigid limiting and locking structure, resulting in poor overall structural rigidity and resistance to deformation. When the backboard assembly is subjected to impacts from the front and back, especially from the back of the backboard to the front, the multi-hinged structure is prone to rotation around the hinge points, failing to form effective collinear rigid support. This makes it difficult to effectively restrain the hoop, causing significant swaying. This swaying not only reduces the stability of the hoop, interferes with the accuracy of subsequent shots, and affects the user experience, but also accelerates fatigue wear on key connection points such as the hinge points between the hoop and the crossbeam, thereby reducing the equipment's lifespan and reliability. Summary of the Invention

[0008] The purpose of this invention is to provide a suspended basketball hoop that maintains structural stability when subjected to external impact in its unfolded state, preventing the basketball hoop from shaking and thus improving the stability and safety of the basketball hoop.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a suspended basketball hoop, comprising a front hanger, a rear hanger, a main frame, a first supporting sub-frame, a second supporting sub-frame, and a traction mechanism; The front and rear hangers are arranged in a front-to-back configuration and are fixedly connected to the roof beams of the indoor venue; The upper end of the main frame is hinged to the lower end of the rear hanger, and a backboard assembly is installed at the lower end of the main frame; the first support sub-frame and the second support sub-frame are both located on the front side of the main frame. The upper end of the first support sub-frame is hinged to the lower end of the front hanger, the lower end of the first support sub-frame is hinged to the upper end of the second support sub-frame, and the lower end of the second support sub-frame is hinged to the lower end of the main frame. A limiting plate is fixed at the lower end of the first supporting sub-frame. The limiting plate is located above the hinge point between the first supporting sub-frame and the second supporting sub-frame, and extends beyond the hinge point to the lower end of the first supporting sub-frame so that the second supporting sub-frame can abut against it. When the second supporting sub-frame is flipped and unfolded relative to the first supporting sub-frame to abut against the limiting plate, the first supporting sub-frame and the second supporting sub-frame are unfolded into a straight line. At this time, the first supporting sub-frame and the second supporting sub-frame, which are in a straight line, together constitute a diagonal brace frame that supports and locks the main frame in a vertical use posture. The traction mechanism is connected to the lower end of the first support sub-frame and is used to pull the lower end of the first support sub-frame upwards, so as to drive the first support sub-frame and the second support sub-frame, which are unfolded in a straight line, to fold around their hinge and flip towards the roof beam; at the same time, through the hinge linkage between the lower end of the second support sub-frame and the lower end of the main frame, the main frame is driven to flip around its hinge with the rear hanger towards the roof beam, so that the first support sub-frame, the second support sub-frame and the main frame are all gathered together in the roof beam.

[0010] Furthermore, in the aforementioned suspended basketball hoop, the traction mechanism includes a winding wheel, a winding wheel rotation drive mechanism, and a steel wire rope; The winding wheel is rotatable about its own axis and is supported by the roof beam of the indoor venue. The winding wheel rotation drive mechanism is connected to the winding wheel to drive the winding wheel to rotate forward or in reverse. Transition wheels that can rotate freely around their own axes are respectively installed on the upper middle part of the first supporting sub-frame, the lower middle part of the second supporting sub-frame, the upper middle part of the main frame, and the indoor stadium roof beam between the front hanger and the rear hanger. One end of the wire rope is fixed to the axle of the winding wheel, and the other end of the wire rope passes in sequence over the transition wheel at the middle of the upper end of the first support sub-frame, the transition wheel at the middle of the lower end of the second support sub-frame, the transition wheel at the middle of the upper end of the main frame, and the transition wheel on the roof beam of the indoor stadium, and is then fixedly connected to the middle of the lower end of the first support sub-frame. When the winding wheel rotation drive mechanism drives the winding wheel to rotate forward and release the wire rope, the main frame, the first support sub-frame and the second support sub-frame rotate and unfold around the corresponding hinge under their own gravity until the second support sub-frame rotates and abuts against the limiting plate so that it is in a straight line with the first support sub-frame. At this time, the main frame also rotates around the corresponding hinge to the vertical use posture. At this time, the first support sub-frame and the second support sub-frame, which are in a straight line, together form a diagonal brace frame to support and lock the main frame in the vertical use posture. When the winding wheel rotation drive mechanism drives the winding wheel to reverse and wind the wire rope, the wire rope pulls the lower end of the first support sub-frame upwards, causing the first and second support sub-frames, which are unfolded in a straight line, to fold around their hinge and flip towards the roof beam. At the same time, through the hinge linkage between the lower end of the second support sub-frame and the lower end of the main frame, the main frame is driven to flip around its hinge with the rear hanger towards the roof beam, so that the first support sub-frame, the second support sub-frame, and the main frame are all gathered together on the roof beam.

[0011] Furthermore, in the aforementioned suspended basketball hoop, the winding wheel rotation drive mechanism includes a motor and a reducer. A drive pulley is mounted on the output shaft of the motor, and a driven pulley is mounted on the input shaft of the reducer. A transmission belt is wound between the drive pulley and the driven pulley, and the output shaft of the reducer is coaxially connected to the axle of the winding wheel.

[0012] Furthermore, in the aforementioned suspended basketball hoop, the connection structure between the rear hanger and the roof beam is as follows: the rear hanger has two rear hanger rods distributed to the left and right, and a first mounting plate is fixed to the top of each of the two rear hanger rods; the two rear hanger rods are correspondingly arranged with two parallel connecting beams on the roof beam, and two first U-bolts are correspondingly arranged above each rear hanger rod; each first U-bolt is fitted downwards onto the corresponding connecting beam with its opening facing downwards, and the threaded portions on both sides of the first U-bolt pass downwards through the first mounting plate at the top of the corresponding rear hanger rod and are threaded with a first fastening nut.

[0013] Furthermore, in the aforementioned suspended basketball hoop, the connection structure between the front hanger and the roof beam is as follows: the front hanger has two front hanger rods distributed to the left and right, and a second mounting plate is fixed to the top of each of the two front hanger rods; the two front hanger rods are correspondingly arranged with two parallel connecting beams on the roof beam, and two second U-bolts are correspondingly arranged above each front hanger rod; each second U-bolt is fitted downwards onto the corresponding connecting beam with its opening facing downwards, and the threaded portions on both sides of the second U-bolt pass downwards through the second mounting plate at the top of the corresponding front hanger rod and are threaded with a second fastening nut.

[0014] The beneficial effects of implementing the above technical solution are as follows: (1) When the basketball hoop is in the unfolded state, the first support sub-frame and the second support sub-frame are limited by the limiting plate designed at a specific position to form a straight rigid bracing frame. When subjected to external impact, the straight bracing frame will not fold, thereby locking the main frame in a stable vertical position, thus effectively preventing the basketball hoop from shaking when subjected to external impact. When it is necessary to fold it up, only the lower end of the first support sub-frame needs to be pulled. Through the hinge linkage between the three frames, the first support sub-frame, the second support sub-frame and the main frame can be rotated around the corresponding hinge axis and folded up smoothly together on the roof beam. This realizes the convenient switching between unfolding and locking and folding and folding, which greatly improves the stability, safety and ease of operation.

[0015] (2) The basketball hoop can be electrically deployed and retracted by driving the winding wheel with an electric motor and a reducer. The specific winding arrangement of the wire rope allows the wire rope to play a traction and support role during the retraction process, making the retraction action more stable and effortless. At the same time, the wire rope can limit the frame from falling accidentally in both the retracted and deployed states. Combined with the reliable locking of the winding wheel by the self-locking reducer, the safety of use is further improved.

[0016] (3) Both the front and rear hangers are fixed to the connecting beam of the roof beam frame by U-bolts. The front and rear positions can be adjusted along the direction of the connecting beam by loosening the fastening nuts. The installation and positioning are convenient and can meet the installation needs of different venues. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] For ease of description, let's use Figure 1 The left-hand direction is defined as "forward". Figure 1 The right-hand direction is defined as "back". Figure 1 "Above" is defined as "above". Figure 1 The term "down" is defined as "below" and a coordinate system is established based on it to determine the directions "left", "right", "front", "back", "up" and "down". All directional terms involving the directions "front", "back", "left", "right", "up" and "down" in this invention are defined based on this direction.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, a suspended basketball hoop includes a front hanger 1, a rear hanger 2, a main frame 3, a first supporting sub-frame 4, a second supporting sub-frame 5, and a traction mechanism; the main frame 3, the first supporting sub-frame 4, and the second supporting sub-frame 5 are all frame structures welded together from multiple horizontal bars, vertical bars, and diagonal bars.

[0030] The front hanger 1 and the rear hanger 2 are arranged in a front-to-back manner and are fixedly connected to the connecting beam 101 of the roof beam frame 100 of the indoor venue; The upper end of the main frame 3 is hinged to the lower end of the rear hanger 2 via the first hinge shaft 7. The lower end of the main frame 3 is equipped with a backboard assembly 8, which consists of a backboard fixedly installed at the lower end of the main frame 3 and a rim installed on the backboard. The first supporting sub-frame 4 and the second supporting sub-frame 5 are both located on the front side of the main frame 3. The upper end of the first support sub-frame 4 is hinged to the lower end of the front hanger 1 via the second hinge shaft 9, the lower end of the first support sub-frame 4 is hinged to the upper end of the second support sub-frame 5 via the third hinge shaft 10, and the lower end of the second support sub-frame 5 is hinged to the lower end of the main frame 3 via the fourth hinge shaft 27. A limiting plate 6 is fixed at the lower end of the first supporting sub-frame 4. The limiting plate 6 is located above the third hinge axis 10 of the first supporting sub-frame 4 and the second supporting sub-frame 5, and extends beyond the third hinge axis 10 to the lower end of the first supporting sub-frame 4 so that the second supporting sub-frame 5 can abut against it. When the second supporting sub-frame 5 is rotated and unfolded relative to the first supporting sub-frame 4 around the third hinge axis 10 until it abuts against the limiting plate 6, the first supporting sub-frame 4 and the second supporting sub-frame 5 are unfolded into a straight line. At this time, the first supporting sub-frame 4 and the second supporting sub-frame 5, which are in a straight line, together constitute a diagonal brace frame that supports and locks the main frame 3 in a vertical use posture. The traction mechanism is connected to the lower end of the first support sub-frame 4 and is used to pull the lower end of the first support sub-frame 4 upward, so as to drive the first support sub-frame 4 and the second support sub-frame 5, which are unfolded in a straight line, to fold around the third hinge axis 10 and flip towards the roof beam 100; at the same time, through the hinge linkage between the lower end of the second support sub-frame 5 and the lower end of the main frame 3, the main frame 3 is driven to flip around the first hinge axis 7 towards the roof beam 100, so that the first support sub-frame 4, the second support sub-frame 5 and the main frame 3 are all gathered together in the roof beam 100.

[0031] In this embodiment, as Figure 4 , Figure 7 As shown, the traction mechanism includes a winding wheel 11, a winding wheel rotation drive mechanism, and a wire rope 12; The winding wheel 11 is rotatable about its own axis and is supported on the roof beam 100 of the indoor venue; The winding wheel rotation drive mechanism is connected to the winding wheel 11 to drive the winding wheel 11 to rotate forward or in reverse. Transition wheels 13 that can rotate freely around their own axes are respectively provided on the upper middle part of the first supporting sub-frame 4, the lower middle part of the second supporting sub-frame 5, the upper middle part of the main frame 3, and the indoor stadium roof beam frame 100 between the front hanger 1 and the rear hanger 2. One end of the wire rope 12 is fixed to the axle of the winding wheel 11, and the other end of the wire rope 12 passes sequentially around the transition wheel 13 at the middle of the upper end of the first support sub-frame 4, the transition wheel 13 at the middle of the lower end of the second support sub-frame 5, the transition wheel 13 at the middle of the upper end of the main frame 3, and the transition wheel 13 on the roof beam 100 of the indoor stadium, and is then fixedly connected to the middle of the lower end of the first support sub-frame 4. When the winding wheel rotation drive mechanism drives the winding wheel 11 to rotate forward and release the wire rope 12, the main frame 3, the first support sub-frame 4 and the second support sub-frame 5 will rotate and unfold around the corresponding hinge under their own gravity until the second support sub-frame 5 rotates and abuts against the limiting plate 6 so that it is in a straight line with the first support sub-frame 4. At this time, the main frame 3 also rotates around the corresponding hinge to the vertical use posture. At this time, the first support sub-frame 4 and the second support sub-frame 5, which are in a straight line, together form a diagonal brace frame to support and lock the main frame 3 in the vertical use posture. When the winding wheel rotation drive mechanism drives the winding wheel 11 to reverse and wind the wire rope 12, the wire rope 12 pulls the lower end of the first support sub-frame 4 upward, thereby causing the first support sub-frame 4 and the second support sub-frame 5, which are unfolded in a straight line, to fold around the third hinge axis 10 and flip towards the roof beam 100; at the same time, through the hinge linkage between the lower end of the second support sub-frame 5 and the lower end of the main frame 3, the main frame 3 is driven to flip around the first hinge axis 7 towards the roof beam 100, so that the first support sub-frame 4, the second support sub-frame 5 and the main frame 3 are all gathered together in the roof beam 100; During the process of retracting the first supporting sub-frame 4, the second supporting sub-frame 5, and the main frame 3 together upwards to the roof beam 100, the steel wire rope 12 not only pulls the lower end of the first supporting sub-frame 4 upwards to rotate, but also supports the lower ends of the main frame 3 and the second supporting sub-frame 5 upwards, making the retraction action more stable and effortless; moreover, the steel wire rope 12 can also limit the accidental downward fall of each frame, improving the overall safety of the basketball hoop.

[0032] In this embodiment, the winding pulley rotation drive mechanism includes a motor 14 and a reducer 15. The reducer 15 is a commercially available reducer with a self-locking function. A drive pulley 16 is mounted on the output shaft of the motor 14, and a driven pulley 17 is mounted on the input shaft of the reducer 15. A transmission belt 18 is wound between the drive pulley 16 and the driven pulley 17. The output shaft of the reducer 15 is coaxially connected to the axle of the winding pulley 11. When the motor stops rotating, the reducer can reliably lock the winding pulley, thereby locking the wire rope and ensuring the stability of the basketball hoop in both the folded and unfolded states, thus improving the overall safety and reliability of the basketball hoop.

[0033] In this embodiment, the connection structure between the rear hanger 2 and the roof beam 100 is as follows: the rear hanger 2 has two rear hanger rods 19 distributed to the left and right, and the top of each of the two rear hanger rods 19 is fixed with a first mounting plate 20; the two rear hanger rods 19 are arranged one-to-one with the two parallel connecting beams 101 on the roof beam 100, and two first U-bolts 21 are provided above each rear hanger rod 19; each first U-bolt 21 is sleeved downward on the corresponding connecting beam 101 with its opening facing downward, and the threaded portions on both sides of the first U-bolt 21 pass downward through the first mounting plate 20 at the top of the corresponding rear hanger rod 19 and are threaded with a first fastening nut 22. The connection structure between the front hanger 1 and the roof beam 100 is as follows: the front hanger 1 has two front hanger rods 23 distributed on the left and right, and the top of each of the two front hanger rods 23 is fixed with a second mounting plate 24; the two front hanger rods 23 are arranged one-to-one with the two parallel connecting beams 101 on the roof beam 100, and two second U-bolts 25 are provided on the top of each front hanger rod 23; each second U-bolt 25 is sleeved downward on the corresponding connecting beam 101 with the opening facing downward, and the threaded parts on both sides of the second U-bolt 25 pass downward through the second mounting plate 24 at the top of the corresponding front hanger rod 23 and are threaded with a second fastening nut 26.

[0034] By adopting the above-mentioned connection structure between the rear hanger 2 and the roof beam 100, and the connection structure between the front hanger 1 and the roof beam 100, the front and rear positions of the basketball hoop as a whole on the roof beam 100 can be easily adjusted.

[0035] The working principle of this invention is as follows: During installation, the front hanger 1 and the rear hanger 2 are fixed to the connecting beam 101 of the roof beam 100 using U-bolts. After loosening the corresponding fastening nuts, the front and rear positions of the front hanger 1 and the rear hanger 2 can be adjusted along the direction of the connecting beam 101, thereby facilitating the adjustment of the overall position of the basketball hoop on the roof beam 100 to meet the installation requirements of different venues. After the position adjustment is completed, tightening the fastening nuts completes the installation positioning.

[0036] In the initial state, the basketball hoop is in the retracted state. In the retracted state, the first supporting sub-frame 4, the second supporting sub-frame 5, and the main frame 3 are all retracted together to the roof beam 100.

[0037] When the basketball hoop is needed, the motor 14 is started and rotates forward. The motor 14 drives the reducer 15 through the driving pulley 16, the transmission belt 18, and the driven pulley 17. The reducer 15 drives the winding wheel 11 to rotate forward and release the wire rope 12. As the wire rope 12 is released, the main frame 3, the first support sub-frame 4, and the second support sub-frame 5 rotate downward and unfold around their respective hinge axes under their own gravity. During this process, the main frame 3 swings downward and backward relative to the rear hanger 2 around the first hinge axis 7, the first support sub-frame 4 swings downward and forward relative to the front hanger 1 around the second hinge axis 9, and the second support sub-frame 5 rotates downward and backward relative to the first support sub-frame 4 around the third hinge axis 10. When the second support sub-frame 5 rotates and abuts against the limiting plate 6, the first support sub-frame 4 and the second support sub-frame 5 are exactly unfolded into a straight line, and at the same time, the main frame 3 also swings to a vertical use position. At this time, the first support sub-frame 4 and the second support sub-frame 5, which are in a straight line, together form a diagonal bracing frame. This diagonal bracing frame stably supports and locks the main frame 3 in a vertical use position. At this time, the basketball hoop is in the unfolded use state.

[0038] When the basketball hoop is in its unfolded state, with the first supporting sub-frame 4 and the second supporting sub-frame 5 aligned and the main frame 3 in a vertical position, and the backboard assembly 8 is subjected to an impact force (i.e., a forward impact) from the front to the back of the backboard, the impact force is transmitted along the axial direction of the two sub-frames because the first supporting sub-frame 4 and the second supporting sub-frame 5 are exactly collinear. No lateral component force perpendicular to the sub-frame axis is generated at the third hinge axis 10 between them, preventing the frame from folding. Therefore, the first supporting sub-frame 4 and the second supporting sub-frame 5 will not fold at the third hinge axis 10. At this time, the diagonal brace... The frame firmly supports the main frame to prevent the basketball hoop from wobbling. When the backboard assembly is subjected to an impact force from the back of the backboard to the front (i.e., a backward impact), the second supporting sub-frame 5 is restricted by the limiting plate 6, preventing it from rotating upward relative to the first supporting sub-frame 4 from its collinear position around the third hinge axis 10. In other words, the first and second supporting sub-frames 4 will not fold at the third hinge axis 10 and remain collinear. At this point, the diagonal bracing frame holds the basketball hoop in place, preventing it from wobbling. In other words, when the backboard assembly 8 is impacted, the first and second supporting sub-frames 4 and 5 remain in a straight line. The diagonal bracing frame formed by the first and second supporting sub-frames 4 and 5, the main frame 3, and the connecting beam 101 form a stable triangular support structure, effectively preventing the basketball hoop from wobbling and improving its stability and safety.

[0039] When the basketball hoop needs to be retracted, the motor 14 is started and reversed, driving the winding wheel 11 to reverse and wind the wire rope 12. The winding direction of the wire rope 12 is as follows: Figure 1 As indicated by the middle arrow, the steel wire rope 12 pulls the lower end of the first support sub-frame 4 upward and flips it, causing the first support sub-frame 4 to swing upward and backward around the second hinge axis 9. Through the hinge linkage between the first support sub-frame 4, the second support sub-frame 5, and the main frame 3, during the upward and backward swing of the first support sub-frame 4 around the second hinge axis 9, the second support sub-frame 5 folds upward and forward relative to the first support sub-frame 4 around the third hinge axis 10. At the same time, the second support sub-frame 5 folds relative to the main frame 3 around the fourth hinge axis 27, and causes the main frame 3 to swing upward and forward around the first hinge axis 7. Finally, the first support sub-frame 4, the second support sub-frame 5, and the main frame 3 are all gathered together at the roof beam 100.

[0040] Throughout the retraction process, the steel wire rope 12 not only provides traction but also supports the lower ends of the main frame 3 and the second support sub-frame 5, making the retraction action smoother and less strenuous. Furthermore, the steel wire rope 12 prevents the frames from accidentally falling downwards, improving the overall safety of the basketball hoop. Simultaneously, when the motor 14 stops rotating, the self-locking reducer 15 reliably locks the winding wheel 11, thereby locking the steel wire rope 12 and ensuring the stability of the basketball hoop in both the retracted and unfolded states, further enhancing overall safety and reliability.

[0041] The advantages of this invention are: (1) When the basketball hoop is in the unfolded state, the first support sub-frame and the second support sub-frame are limited by the limiting plate designed at a specific position to form a straight rigid bracing frame. When subjected to external impact, the straight bracing frame will not fold, thereby locking the main frame in a stable vertical position, thus effectively preventing the basketball hoop from shaking when subjected to external impact. When it is necessary to fold it up, only the lower end of the first support sub-frame needs to be pulled. Through the hinge linkage between the three frames, the first support sub-frame, the second support sub-frame and the main frame can be rotated around the corresponding hinge axis and folded up smoothly together on the roof beam. This realizes the convenient switching between unfolding and locking and folding and folding, which greatly improves the stability, safety and ease of operation.

[0042] (2) The basketball hoop can be electrically deployed and retracted by driving the winding wheel with an electric motor and a reducer. The specific winding arrangement of the wire rope allows the wire rope to play a traction and support role during the retraction process, making the retraction action more stable and effortless. At the same time, the wire rope can limit the frame from falling accidentally in both the retracted and deployed states. Combined with the reliable locking of the winding wheel by the self-locking reducer, the safety of use is further improved.

[0043] (3) Both the front and rear hangers are fixed to the connecting beam of the roof beam frame by U-bolts. The front and rear positions can be adjusted along the direction of the connecting beam by loosening the fastening nuts. The installation and positioning are convenient and can meet the installation needs of different venues.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any modifications or equivalent changes made based on the technical essence of the present invention shall still fall within the scope of protection claimed by the present invention.

A limiting plate is fixed at the lower end of the first supporting sub-frame. The limiting plate is located above the hinge point between the first supporting sub-frame and the second supporting sub-frame, and extends beyond the hinge point to the lower end of the first supporting sub-frame so that the second supporting sub-frame can abut against it. When the second supporting sub-frame is flipped and unfolded relative to the first supporting sub-frame to abut against the limiting plate, the first supporting sub-frame and the second supporting sub-frame are unfolded into a straight line. At this time, the first supporting sub-frame and the second supporting sub-frame, which are in a straight line, together constitute a diagonal brace frame that supports and locks the main frame in a vertical use posture. The traction mechanism is connected to the lower end of the first support sub-frame and is used to pull the lower end of the first support sub-frame upwards, so as to drive the first support sub-frame and the second support sub-frame, which are unfolded in a straight line, to fold around their hinge and flip towards the roof beam; at the same time, through the hinge linkage between the lower end of the second support sub-frame and the lower end of the main frame, the main frame is driven to flip around its hinge with the rear hanger towards the roof beam, so that the first support sub-frame, the second support sub-frame and the main frame are all gathered together in the roof beam.

2. A suspended basketball hoop according to claim 1, characterized in that: The traction mechanism includes a winding reel, a winding reel rotation drive mechanism, and a wire rope; The winding wheel is rotatable about its own axis and is supported by the roof beam of the indoor venue. The winding wheel rotation drive mechanism is connected to the winding wheel to drive the winding wheel to rotate forward or in reverse. Transition wheels that can rotate freely around their own axes are respectively installed on the upper middle part of the first supporting sub-frame, the lower middle part of the second supporting sub-frame, the upper middle part of the main frame, and the indoor stadium roof beam between the front hanger and the rear hanger. One end of the wire rope is fixed to the axle of the winding wheel, and the other end of the wire rope passes in sequence over the transition wheel at the middle of the upper end of the first support sub-frame, the transition wheel at the middle of the lower end of the second support sub-frame, the transition wheel at the middle of the upper end of the main frame, and the transition wheel on the roof beam of the indoor stadium, and is then fixedly connected to the middle of the lower end of the first support sub-frame. When the winding wheel rotation drive mechanism drives the winding wheel to rotate forward and release the wire rope, the main frame, the first support sub-frame and the second support sub-frame rotate and unfold around the corresponding hinge under their own gravity until the second support sub-frame rotates and abuts against the limiting plate so that it is in a straight line with the first support sub-frame. At this time, the main frame also rotates around the corresponding hinge to the vertical use posture. At this time, the first support sub-frame and the second support sub-frame, which are in a straight line, together form a diagonal brace frame to support and lock the main frame in the vertical use posture. When the winding wheel rotation drive mechanism drives the winding wheel to reverse and wind the wire rope, the wire rope pulls the lower end of the first support sub-frame upwards, causing the first and second support sub-frames, which are unfolded in a straight line, to fold around their hinge and flip towards the roof beam. At the same time, through the hinge linkage between the lower end of the second support sub-frame and the lower end of the main frame, the main frame is driven to flip around its hinge with the rear hanger towards the roof beam, so that the first support sub-frame, the second support sub-frame, and the main frame are all gathered together on the roof beam.
