Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to a backboard and rim mounting structure and a basketball hoop. Background Technology

[0002] A basketball hoop is an essential piece of sports equipment for basketball. A basketball hoop generally includes a post, an extension arm mounted on the top of the post, and a backboard and rim mounted on the front of the extension arm. The backboard and rim are common components of a basketball hoop. The backboard typically consists of a rectangular board with a square notch in the center of its bottom edge. The board is fitted and fixed within a rectangular frame, and the lower edge of the frame and the square notch on the bottom edge of the board form a mounting opening on the underside of the backboard. The structure of the rim is described in invention patent application number 201710679514.8.

[0003] Currently, the installation structure of the backboard and rim on the extension arm in a basketball hoop is as follows: A mounting bracket is provided at the front end of the extender arm. Two ear plates are fixed at the rear end of the mounting bracket, located on the left and right sides of the front end of the extender arm respectively. Each ear plate has a through hole, and the through holes of the two ear plates are coaxial and symmetrical. On the left and right side walls of the front end of the extender arm, a screw hole corresponding to the through hole of the corresponding ear plate is provided coaxially. A locking bolt is provided in the corresponding through hole and thread on each side. The screw of each locking bolt passes through the corresponding through hole and is threaded into the corresponding screw hole, thereby locking and fixing the mounting bracket to the front end of the extender arm. The mounting bracket is fitted over the lower frame strip at the mounting opening on the underside of the backboard. The backboard rests downwards on the mounting bracket via the lower frame strip, and the lower frame strip of the backboard is fixedly connected to the mounting bracket to secure the backboard together. The upper end of the backboard is connected to the extension arm via an upper pull rod, thereby mounting the backboard onto the extension arm. The front end of the mounting bracket is fixedly connected to the basketball hoop connecting seat at the rear end of the elastic basketball hoop, so that the elastic basketball hoop is fixed together with the mounting bracket, thereby allowing the elastic basketball hoop to be installed on the extension arm.

[0004] In practical applications, the backboard body is mostly made of tempered glass, the backboard frame is mostly made of aviation aluminum profile, and the mounting bracket and the rim connection seat of the elastic rim are mostly made of high-strength steel. Furthermore, for safety reasons, in order to prevent athletes' fingers from getting caught in the gap between the mounting bracket and the edge of the backboard mounting opening when performing a dunking action, the industry standard requires that the gap should not be greater than 8cm.

[0005] During the use of a basketball hoop, when an athlete dunks, the elastic rim is subjected to a downward force and swings downward relative to the backboard. When the athlete completes the dunk and releases the rim, the rim will quickly bounce upward and return to its original position under the elastic force of the internal spring.

[0006] The aforementioned backboard and rim mounting structure has the following drawbacks: When the pair of locking bolts connecting the mounting base to the front end of the extension arm loosens, after the athlete completes the dunk and releases the elastic rim, the rim will quickly spring upwards to its original position under the force of its internal spring. This upward movement exerts an upward force on the mounting frame. Since the strength of the mounting frame is much greater than that of the backboard's aluminum frame, the mounting frame, under the excessive upward instantaneous force exerted by the rim, will rotate upwards relative to the backboard around the locking bolts. On one hand, this upward rotation of the mounting frame relative to the backboard will twist the lower edge of the aluminum frame, causing deformation. Severe deformation can shatter the tempered glass. On the other hand, because the gap between the mounting frame and the edge of the backboard mounting opening is small, the mounting frame can easily contact and crush the tempered glass when rotating upwards relative to the backboard, causing it to break and affecting the safety of the basketball hoop. Utility Model Content

[0007] The first objective of this invention is to provide a backboard and rim mounting structure with high safety.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a backboard and rim mounting structure, including an extension arm, a backboard, and an elastic rim. A mounting frame is provided at the mounting opening on the lower side of the backboard. The mounting frame is fixedly connected to the lower frame strip at the mounting opening on the lower side of the backboard to fix the backboard to the mounting frame. The elastic rim is fixedly connected to the front end of the mounting frame. Two mounting plates distributed on the left and right are fixedly connected to the rear end of the mounting frame. The two mounting plates are coaxially fixedly connected to the extension arm through a locking mechanism, so that the mounting frame is fixedly connected to the front end of the extension arm. A front end plate is fixed at the front end of the extension arm. Two anti-rotation limiting members are provided on the front end plate, which are distributed vertically and protrude forward from the front end plate. The two anti-rotation limiting members are respectively forward and close to the upper and lower areas of the rear end of the mounting frame to limit the vertical rotation of the mounting frame.

[0009] Furthermore, in the aforementioned backboard mounting structure, the locking mechanism is structured as follows: Two mounting plates distributed on the left and right sides of the rear end of the mounting frame each have a coaxial first through hole. On the left and right side walls of the front end of the extension arm, a first locking screw hole coaxial with the first through hole is provided. The first through hole on the left mounting plate at the rear end of the mounting frame corresponds to the first locking screw hole on the left side wall of the front end of the extension arm, and the first through hole on the right mounting plate at the rear end of the mounting frame corresponds to the first locking screw hole on the right side wall of the front end of the extension arm. A first locking bolt is simultaneously inserted into the corresponding first locking screw hole and the first through hole on each side. After the screw of each first locking bolt passes through the first through hole on the corresponding side mounting plate, it is threaded into the first locking screw hole on the corresponding side wall of the extension arm. Tightening both first locking bolts simultaneously can coaxially fix the two mounting plates to the extension arm, thereby fixing the mounting frame to the front end of the extension arm.

[0010] Furthermore, in the aforementioned backboard and rim mounting structure, the connection structure between the mounting frame and the two mounting plates at its rear end is as follows: Each of the two mounting plates has a mounting portion at its front end; the front faces of the mounting portions of the two mounting plates together form a mounting plane parallel to the rear end face of the mounting frame. One mounting plate has a positioning hole on its mounting portion, and this positioning hole is directly opposite the center of the rear end face of the mounting frame. Several arc-shaped elongated holes are provided on the mounting portions of both mounting plates, and the centerlines of all the arc-shaped elongated holes lie on the same distributed circle centered on the center of the positioning hole. A rearwardly protruding... The mounting bracket has a positioning shaft on its rear end face that can be fitted with a coaxial insertion positioning hole. The rear end face of the mounting bracket also has connecting screw holes that correspond one-to-one with each arc-shaped elongated hole. An adjusting bolt is installed in each corresponding connecting screw hole and arc-shaped elongated hole. The screw of each adjusting bolt passes through the corresponding arc-shaped elongated hole and is threaded into the corresponding connecting screw hole on the mounting bracket. When the adjusting bolts are loosened, the backboard can rotate left and right relative to the mounting plate and extension arm around the positioning shaft and along the arc-shaped elongated hole to adjust the backboard to a horizontal position. When the backboard is adjusted to a horizontal position and the adjusting bolts are tightened, the adjusting bolts can keep the backboard in a horizontal position and lock it to the extension arm.

[0011] Furthermore, in the aforementioned backboard rim mounting structure, the two anti-rotation limiting components are two threaded limiting bolts connected to the front end plate of the extension arm. Both limiting bolts extend forward from the front end plate and respectively face forward towards the upper and lower areas of the rear end of the mounting frame, so as to limit the vertical rotation of the mounting frame.

[0012] Furthermore, in the aforementioned backboard and rim mounting structure, a tightening nut is threaded onto each limiting bolt.

[0013] Furthermore, in the aforementioned backboard mounting structure, a U-shaped pull rod is provided between the backboard and the extension arm. The two ends of the pull rod are respectively hinged to the upper end of the backboard back via coaxial pins. Two sets of front-to-back adjustable elongated holes are provided on the top wall of the middle section of the extension arm. The length direction of the adjustable elongated holes is consistent with the length direction of the extension arm. The middle part of the pull rod rests on the top area of ​​the extension arm between the two sets of adjustable elongated holes. A pull rod pressure plate is provided above the middle part of the pull rod to press the middle part of the pull rod downwards onto the extension arm. Mounting holes corresponding to the adjustable elongated holes on the corresponding sides are provided at the front and rear ends of the pull rod pressure plate. A connecting bolt passes through each corresponding adjustable elongated hole and mounting hole. The thread of each connecting bolt passes through the corresponding mounting hole and adjusting elongated hole and is threaded to a connecting nut. When each connecting nut is tightened, the pull rod pressure plate presses the pull rod downwards, thereby positioning the pull rod to synchronously position the backboard.

[0014] Furthermore, in the aforementioned backboard rim mounting structure, a baffle is provided directly in front of the gap between the mounting bracket and the edge of the mounting opening on the lower side of the backboard to block the gap. The baffle is installed at the rear end of the elastic rim or the front end of the mounting bracket.

[0015] The second objective of this invention is to provide a basketball hoop with high safety features.

[0016] To achieve the above objectives, the present invention adopts the following technical solution: a basketball hoop, including a column, an extension arm installed at the upper end of the column, and a backboard and an elastic rim installed at the front end of the extension arm, wherein the backboard and the elastic rim are installed on the extension arm using the backboard and rim installation structure described in the present invention.

[0017] Through the implementation of the above technical solutions, the beneficial effects of this utility model are: (1) By using the upper and lower distributed limit bolts, the up and down rotation of the mounting frame caused by the impact of the basketball hoop is effectively suppressed, fundamentally avoiding the risk of the backboard glass being crushed, and the safety of use is high; (2) By using the design of "mounting frame positioning shaft + mounting plate arc-shaped long hole", the backboard can rotate flexibly left and right around the positioning shaft. The backboard can be easily adjusted to an absolute level by loosening the adjusting bolts, and then locked and fixed, effectively compensating for installation errors and ensuring that the basketball hoop and backboard are in a standard level state in the horizontal direction, which is suitable for various installation environments; (3) The design of the pull rod increases the connection strength between the backboard and the extension arm, and by using the U-shaped pull rod and the upper and lower limit bolts, the pitch angle of the backboard can be further finely adjusted, effectively compensating for installation errors and ensuring that the backboard remains upright in the vertical direction.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 As shown, a backboard and rim mounting structure includes an extender arm 1, a backboard 2, and a flexible rim 3. A mounting bracket 4 is provided at the mounting opening 21 on the lower side of the backboard 2. The mounting bracket 4 is fitted over the lower frame strip 22 at the mounting opening 21 on the lower side of the backboard, so that the backboard 2 is placed on the mounting bracket 4 through its lower frame strip 22. The rear side plate 221 of the lower frame strip 22 at the mounting opening 21 of the backboard 2 is fixedly connected to the rear end of the mounting bracket 4 by a number of rear fixing bolts 6. The front end of the mounting bracket 4 is fixedly connected to the rim connecting seat 31 at the rear end of the flexible rim 3 by a number of front fixing bolts 7. Some of the front fixing bolts 7 are used when connecting the mounting bracket 4 and the rim connecting seat 31. 7 also passes through the front side plate 222 of the lower frame strip 22 at the backboard mounting opening 21. That is, in this embodiment, when the backboard 2 is placed on the mounting frame 4 through its lower frame strip 22, the rear side plate 221 of the lower frame strip 22 at the backboard mounting opening 21 is fixedly connected to the rear end of the mounting frame 4 by a number of rear fixing bolts 6, and the front side plate 222 of the lower frame strip 22 at the backboard mounting opening 21 is fixedly connected to the front end of the mounting frame 4 by a number of front fixing bolts 7, thereby fixing the backboard 2 to the mounting frame 4; and the front end of the mounting frame 4 is fixedly connected to the rim connection seat 31 at the rear end of the elastic rim 3 by a number of front fixing bolts 7, thereby fixing the elastic rim 3 to the mounting frame 4. In this embodiment, a baffle 32 is provided in front of the gap 100 between the mounting bracket 4 and the edge of the mounting opening 21 on the lower side of the backboard to block the gap 100. The baffle 32 is installed at the rear end of the elastic rim or the front end of the mounting bracket. In this embodiment, the baffle 32 is installed at the rear end of the rim connecting seat 31 of the elastic rim 3. Through the design of the baffle 32, the fingers of the athlete can be further prevented from getting stuck in the gap 100 when dunking, thus improving the safety of use.

[0035] Two mounting plates 5, distributed left and right, are fixedly connected to the rear end of the mounting bracket 4. The two mounting plates 5 are coaxially fixedly connected to the extension arm 1 by a locking mechanism to fix the mounting bracket 4 to the front end of the extension arm 1; in this embodiment, as Figure 2 , Figure 4 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 As shown, the connection structure between the mounting bracket 4 and the two mounting plates 5 at its rear end is as follows: A mounting part 51 is provided at the front end of each of the two mounting plates 5. The front ends of the mounting parts of the two mounting plates 5 together form a mounting plane parallel to the rear end face of the mounting bracket. A positioning hole 52 is provided on the mounting part 51 of one of the mounting plates 5, and this positioning hole 52 is directly opposite the center of the rear end face of the mounting bracket 4. Several arc-shaped elongated holes 53 are provided on the mounting parts 51 of the two mounting plates 5. The center line m of all the arc-shaped elongated holes 53 lies on the same distributed circle n centered on the center O of the positioning hole 52. A positioning shaft 41 is provided at the center of the rear end of the mounting bracket 4, protruding rearward from the rear end face of the mounting bracket 4 and capable of being coaxially inserted into the positioning hole 52. A connection between the arc-shaped elongated holes 53 and the rear end face of the mounting bracket 4 is also provided. Each corresponding connecting screw hole 42 has an adjusting bolt 43 installed in each corresponding connecting screw hole 42 and arc-shaped elongated hole 53. The screw of each adjusting bolt 43 passes through the corresponding arc-shaped elongated hole 53 and is threaded into the corresponding connecting screw hole 42 on the mounting bracket 4. When each adjusting bolt 43 is loosened, the backboard 2 and the elastic rim 3 can rotate left and right relative to the mounting plate 4 and the extension arm 1 around the positioning axis 41 and along the arc-shaped elongated hole 53. At this time, the backboard 2 can be adjusted to be horizontal by rotating it to the left or right, and then the elastic rim 3 fixed to the backboard 2 can be adjusted to be horizontal at the same time. After the backboard 2 is adjusted to be horizontal, tighten each adjusting bolt 43 so that each adjusting bolt 43 locks each mounting plate 5 and the mounting bracket 4 together again, so that the backboard 2 is kept horizontal and locked to the extension arm 1.

[0036] In this embodiment, as Figure 4 , Figure 13 , Figure 14 , Figure 15 As shown, the locking mechanism that coaxially fixes the two mounting plates 5 to the front end of the extension arm 1 has the following structure: A first through hole 11 is provided on each of the two mounting plates 5 distributed on the left and right sides of the rear end of the mounting frame 4; a first locking screw hole 12 coaxial with the first through hole 11 is provided on the left and right side walls of the front end of the extension arm 1. The first through hole 11 on the mounting plate 5 on the left side of the rear end of the mounting frame 4 corresponds to the first locking screw hole 12 on the left side wall of the front end of the extension arm 1, and the first through hole 12 on the mounting plate 5 on the right side of the rear end of the mounting frame 4 corresponds to the first locking screw hole 12 on the left side wall of the front end of the extension arm 1. Hole 11 corresponds to the first locking screw hole 12 on the right side wall of the front end of the extension arm 1. A first locking bolt 13 is simultaneously inserted into the first locking screw hole 12 and the first through hole 11 on each side. After the screw of each first locking bolt 13 passes through the first through hole 11 on the corresponding side mounting plate 5, it is threaded into the first locking screw hole 12 on the side wall of the corresponding side extension arm 1. When the two first locking bolts 13 are tightened at the same time, the two mounting plates 5 can be coaxially fixedly connected to the extension arm 1, thereby fixing the mounting bracket 4 to the front end of the extension arm 1.

[0037] A front end plate 8 is fixed to the front end of the extension arm 1, and the front end plate 8 faces forward directly towards the mounting portions 51 of the two mounting plates 5 at the rear end of the mounting bracket 4. Two anti-rotation limiting members, distributed vertically and protruding forward from the front end plate 8, are provided on the front end plate 8. In this embodiment, as shown... Figure 2 , Figure 6 As shown, the two anti-rotation limiting components are two threaded limiting bolts 9 connected to the front end plate of the extension arm. The two limiting bolts 9 are respectively distributed on the upper and lower sides of the first locking bolt 13. Both limiting bolts 9 extend forward from the front end plate 8 and respectively abut forward against the upper and lower areas of the mounting part 51 of the mounting plate 5 with the positioning hole 52. The end face of the mounting part that contacts the two limiting bolts 9 is a flat end face. Thus, when the first locking bolt 13 is loose, under the limiting action of the two limiting bolts 9, the mounting plate 5 cannot rotate up and down around the first locking bolt 13. That is, the upper limiting bolt 9 is used to restrict the mounting plate 5 from rotating upward, and the lower limiting bolt 9 is used to restrict the mounting plate 5 from rotating downward, thereby preventing the mounting bracket 4 fixed to the mounting plate 5 from rotating upward or downward. In this way, (1) when the rim is dunked by the athlete When the downward force is applied, the rim will simultaneously apply a downward force to the mounting bracket 5. At this time, under the limiting action of the lower limit bolt 9, the mounting bracket 5 will not rotate downward even if it is subjected to the downward force of the rim, thereby preventing the mounting bracket 4 from rotating downward and twisting the lower frame strip of the backboard, thus preventing the tempered glass from breaking due to the twisting of the lower frame strip of the backboard; (2) After the athlete completes the dunking action and releases the rim, the rim will quickly bounce upward under the elastic force of its internal spring and apply an upward force to the mounting bracket 5. At this time, under the limiting action of the upper limit bolt 9, the mounting bracket 5 will not rotate upward even if it is subjected to the upward force of the rim, thereby preventing the mounting bracket 4 from rotating upward and contacting and squeezing the tempered glass, thus preventing the mounting bracket 4 from squeezing the tempered glass upward and improving the safety of the basketball hoop. In this embodiment, as Figure 2 , Figure 6 As shown, a tightening nut 10 is threaded onto each limiting bolt 9. The tightening nut 10 can more securely fix the limiting bolt 9 to the front end plate 8 of the extension arm 1, preventing the limiting bolt 9 from loosening during the use of the basketball hoop and ensuring the limiting effect of the limiting bolt 9 on the mounting bracket 4.

[0038] In this embodiment, as Figure 1 , Figure 5 , Figure 7As shown, a U-shaped pull rod 14 is also provided between the backboard 2 and the extension arm. The two ends of the pull rod 14 are respectively hinged to the upper end of the back of the backboard 2 through coaxial pins 15. Two sets of front-to-back adjustable elongated holes 16 are provided on the top wall of the middle part of the extension arm 1. The length direction of the adjustable elongated holes 16 is consistent with the length direction of the extension arm 1, that is, the length direction of the adjustable elongated holes 16 is front-to-back. The middle part of the pull rod 14 rests on the top area of ​​the extension arm between the two sets of adjustable elongated holes 16. A pull rod pressure plate 17 is provided above the middle part of the pull rod 14 to press the middle part of the pull rod downward onto the extension arm 1. The front and rear ends of the pull rod pressure plate 17 are respectively provided with mounting holes corresponding to the corresponding adjustable elongated holes 16. A connecting bolt 19 is passed through each corresponding adjustable elongated hole 16 and mounting hole. The screw of each connecting bolt 19 passes through the corresponding mounting hole and adjustable elongated hole 16. The threaded connection has a connecting nut 20. When each connecting nut 20 is tightened, it can press the pull rod pressure plate 17 downward to tighten the pull rod 14, thereby positioning the pull rod 14 to simultaneously position the backboard 2. Through the auxiliary support of the pull rod 14 for the backboard 2, the connection strength between the backboard 2 and the extension arm 1 is greatly enhanced, so that the backboard can be more firmly connected to the extension arm, improving the overall stability and safety of the basketball hoop. Moreover, in actual assembly, the pull rod 14 can be used with two limit bolts to adjust the pitch angle of the backboard 2.

[0039] During the assembly of the basketball hoop, when it is necessary to adjust the pitch angle of the backboard 2 using two limiting bolts, the first locking bolt 13 and the connecting nut 20 can be loosened. After the first locking bolt 13 is loosened, the backboard 2 can rotate up and down around the first locking bolt 13. After the connecting nut 20 is loosened, the pull rod pressure plate 17 can release the pull rod 14. At this time, the pull rod 14 has an adjustment space for moving back and forth through the cooperation of the connecting bolt 19 and the adjusting elongated hole 16. At this time, the pitch angle of the backboard 2 can be adjusted synchronously by adjusting the extension length of the two limiting bolts. When the upper limiting bolt 9 extends, it can push the backboard 2 to rotate forward and downward around the first locking bolt 12. When the lower limiting bolt 9 extends, it can push the backboard 2 to rotate backward and upward around the first locking bolt 12. After the pitch angle of the backboard is adjusted, the first locking bolt 13 and the connecting nut 20 can be tightened again.

[0040] During the use of the basketball hoop, when the rim is subjected to a downward force by an athlete dunking, and this downward force is transmitted to the mounting bracket 5, the mounting bracket 5 will not rotate downward under the limiting action of the lower limiting bolt 9. This effectively prevents the mounting bracket 4 from rotating downward and twisting the lower frame strip of the backboard, thus avoiding the tempered glass from breaking due to the twisting of the lower frame strip. After the athlete completes the dunking action and releases the rim, the rim bounces upward rapidly under the elastic force of its internal spring, and this upward force is transmitted to the mounting bracket 5. At this time, the mounting bracket 5 will not rotate upward under the limiting action of the upper limiting bolt 9, thus preventing the mounting bracket 4 from rotating upward and contacting and squeezing the tempered glass, and preventing the mounting bracket 4 from squeezing and breaking the tempered glass, thereby improving the safety of the basketball hoop.

[0041] The advantages of the backboard and rim mounting structure described in this utility model are: (1) The upper and lower distribution of the limiting bolts effectively suppresses the up and down rotation of the mounting frame caused by the impact of the rim, fundamentally avoiding the risk of the backboard glass being crushed, and ensuring high safety in use; (2) The design of "mounting frame positioning shaft + mounting plate arc-shaped long hole" allows the backboard to rotate flexibly left and right around the positioning shaft. Loosening the adjusting bolts can easily adjust the backboard to an absolutely horizontal state, and then locking it in place, effectively compensating for installation errors and ensuring that the rim and backboard are in a standard horizontal state, suitable for various installation environments; (3) The design of the pull rod increases the connection strength between the backboard and the extension arm, and through the cooperation of the U-shaped pull rod and the upper and lower limiting bolts, the pitch angle of the backboard can be further finely adjusted, effectively compensating for installation errors and ensuring that the backboard remains upright in the vertical direction.

[0042] This utility model also protects a basketball hoop, including a column, an extension arm 1 installed at the upper end of the column, and a backboard 2 and a flexible rim 3 installed at the front end of the extension arm 1. The backboard 2 and the flexible rim 3 are installed on the extension arm 1 using the backboard and rim mounting structure described in this utility model. Because this basketball hoop uses the backboard and rim mounting structure described in this utility model, it inherits all the advantages of the backboard and rim mounting structure, effectively preventing the backboard glass from breaking when an athlete dunks, greatly improving the stability and safety of the basketball hoop.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any modifications or equivalent changes made based on the technical essence of the present utility model shall still fall within the scope of protection claimed by the present utility model.
