Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0042] refer to Figures 1 to 11 ,like Figure 1 As shown, this embodiment provides a portable folding basketball hoop based on a dual-limit module and an anti-loosening structure. The basketball hoop includes: a base 1, a first limiting module 2, a support column 3, a support rod 4, a backboard 6, a second limiting module 8, and a basket 7. The base 1 is placed on the ground. The first limiting module 2 is installed between the base 1 and the support column 3. The support rod 4 is slidably disposed with respect to the support column 3. The backboard 6 is fixed to the top of the support rod 4. The second limiting module 8 is installed between the backboard 6 and the basket 7. The structure of the second limiting module 8 is the same as that of the first limiting module 2. The first limiting module 2 allows the support column 3 to rotate relative to the base 1, facilitating its transition from an unfolded state to a folded state, and vice versa. Similarly, the second limiting module 8 allows the basket 7 to rotate relative to the backboard 6, facilitating its transition from an unfolded state to a folded state, and vice versa.

[0043] When in use, the support column 3 and the basket 7 are unfolded. After use, the support column 3 and the basket 7 are folded to save space and facilitate storage and transportation.

[0044] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the first limiting module 2 consists of a base 21, a limiting seat 22, and a limiting component 24. The base 21 is fixed to the upper end of the base 1. The base 21 has a U-shaped structure and is made by stamping. The base 21 consists of a mounting plate 211 and a pair of limiting plates 212. The pair of limiting plates 212 are symmetrically fixed at both ends of the mounting plate 211 (e.g., ...). Figure 3 and Figure 4 Each pair of limiting plates 212 has a shaft hole 2123, and the two shaft holes 2123 are coaxially arranged. The upper edge of the limiting plate 212 has a vertical groove 2121, and the side edge has a horizontal groove 2122.

[0045] The upper end of the limiting seat 22 is fixedly connected to the bottom of the support column 3. The lower end of the limiting seat 22 is located between a pair of limiting plates 212. A rotating shaft 23 is fixed at the lower end of the limiting seat 22. The two ends of the rotating shaft 23 are respectively pivotally connected in the corresponding shaft holes 2123. Movable grooves 221 are provided on both sides of the limiting seat 22. The movable grooves 221 are connected to the mounting grooves 222 of the limiting seat 22. A pair of movable grooves 221 are symmetrically arranged on both sides of the mounting grooves 222.

[0046] The limiting assembly 24 consists of an elastic connecting assembly and a limiting post 245. The elastic connecting assembly comprises a connecting rod 2441, a control plate 244, a pair of sliding rods 242, and a compression spring 241. The lower end of the connecting rod 2441 is fixedly connected to the middle of the limiting post 245. The control plate 244 is fixedly connected to the upper end of the connecting rod 2441. The pair of sliding rods 242 are spaced apart and accommodated within the mounting groove 222. The upper ends of the sliding rods 242 are fixed to the top wall of the mounting groove 222. The two ends of the control plate 244 are slidably sleeved on the pair of sliding rods 242. The compression spring 241 connects the top wall of the mounting groove 222 and the control plate 244. An end plate 243 is installed at the lower end of the sliding rod 242. The end plate 243 prevents the control plate 244 from detaching from the sliding rod 242, thus serving as a limiting device.

[0047] The limiting post 245 has a slot 2451. The lower end of the connecting rod 2441 extends into the slot 2451 and is fixed by a cylindrical pin. The cooperation between the connecting rod 2441 and the slot 2451, as well as the fixing by the cylindrical pin, makes the positioning of the connecting rod 2441 and the limiting post 245 more accurate and the connection more secure. The cylindrical pin connection also facilitates the installation and removal of the connecting rod 2441 and the limiting post 245.

[0048] When the support column 3 is in the unfolded state, the limiting column 245 is engaged in the vertical slot 2121. When the support column 3 is in the folded state, the limiting column 245 is engaged in the horizontal slot 2122.

[0049] like Figure 1 , Figure 2 and Figure 4As shown, when the support column 3 and the base 1 are folded, the control plate 244 is raised, which compresses the compression spring 241. At the same time, the limiting column 245 moves upward and disengages from the vertical slot 2121. At this time, the limiting seat 22 is rotated clockwise, and then the control plate 244 is released. Under the reset action of the compression spring 241, the limiting column 245 is locked in the horizontal slot 2122, thus completing the folding.

[0050] like Figure 2 , Figure 4 and Figure 7 As shown, when the support column 3 and the base 1 are unfolded, the control plate 244 is moved to the right, which compresses the compression spring 241. At the same time, the limiting column 245 moves to the right and disengages from the horizontal slot 2122. At this time, the limiting seat 22 is rotated counterclockwise, and then the control plate 244 is released. Under the reset action of the compression spring 241, the limiting column 245 is locked in the vertical slot 2121, and the unfolding is completed.

[0051] like Figure 1 and Figure 7 As shown, the structure of the second limiting module 8 is exactly the same as that of the first limiting module 2. In the second limiting module 8, the base 21 is connected to the left side of the limiting seat 22. The vertical slot 2121 in the second limiting module 8 is located below and to the right of the horizontal slot 2122. In addition, the mounting plate 211 of the base 21 of the second limiting module 8 is fixed to the side of the backboard 6, and the limiting seat 22 of the second limiting module 8 is fixed together with the basket 7. When folding the basket 7, the limiting post 245 is disengaged from the vertical slot 2121, and the basket 7 is rotated counterclockwise so that the limiting post 245 is engaged in the horizontal slot 2122, thus completing the folding of the basket 7 and the backboard 6.

[0052] When unfolding the basket 7, the limiting post 245 disengages from the horizontal slot 2122. The basket 7 is then rotated clockwise so that the limiting post 245 is engaged in the vertical slot 2121, thus completing the unfolding of the basket 7 and the backboard 6.

[0053] like Figure 1 and Figure 2 As shown, the support column 3 is composed of a seat plate 31 and a rectangular column 32. The seat plate 31 and the rectangular column 32 are welded together. The seat plate 31 is fixedly connected to the top of the limiting seat 22. A guide hole is opened in the rectangular column 32, and a pair of through holes are opened on the outer wall. The guide hole is used to accommodate the support rod 4, and the guide hole and the support rod 4 are slidably engaged.

[0054] In one embodiment, such as Figure 1 and Figure 3As shown, the support rod 4 has several adjustment holes 41. The threaded section of the bolt 5 passes through the front through hole, the adjustment hole 41, and the rear through hole in sequence, extending to the rear side of the rectangular column 32. The hexagonal nut 9 is threaded onto the rear end of the threaded section of the bolt 5 to fix the support rod 4 to the rectangular column 32. In use, the bolt 5 is connected to different adjustment holes 41 to achieve the extension and retraction between the support rod 4 and the rectangular column 32, thereby adjusting the height of the basket 7 relative to the ground to meet the needs of people of different heights.

[0055] like Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, an anti-loosening structure 10 is installed on the bolt 5. The anti-loosening structure 10 can lock the hexagonal nut 9 and prevent the hexagonal nut 9 from loosening. The anti-loosening structure 10 consists of an anti-loosening washer 101 and an anti-loosening baffle 102. The anti-loosening washer 101 is sleeved on the bolt 5 and is located between the rectangular column 32 and the hexagonal nut 9.

[0056] A through hole 1022 is provided in the middle of the anti-loosening baffle 102. Knurled screws 103 pass through the through hole 1022 to fix the anti-loosening baffle 102 to the bolt 5. Both ends of the anti-loosening baffle 102 have bent arms 1021. The two bent arms 1021 abut against the two opposite sides of the hexagonal nut 9. The bent arms 1021 can prevent the hexagonal nut 9 from loosening and ensure that the connection between the support rod 4 and the rectangular column 32 is stable and reliable.

[0057] like Figure 11 As shown, the anti-loosening washer 101 has several protrusions 1011 arranged in a ring on it. The protrusions 1011 can increase the anti-slip ability between the anti-loosening washer 101 and the rectangular column 32, and prevent the hexagonal nut 9 from loosening.

[0058] The support column 3 and the support rod 4 are fixed together by bolts 5. When the support rod 4 slides to the bottom of the rectangular column 32, the bolt 5 connects with the bottom adjustment hole 41, thereby reducing the length of the support column 3 and the support rod 4 to the minimum, thus reducing the volume. Furthermore, the support rod 4 can be removed from the support column 3, so that the support rod 4 and the support column 3 can be separated, which can further facilitate transportation and save storage space.

[0059] In summary, this application enables length adjustment between the support column 3 and the support rod 4, folding and unfolding between the support column 3 and the base 1, and folding and unfolding between the basket 7 and the backboard 6, facilitating use and transportation. In the folded state, it is easy to transport and requires minimal storage space.

[0060] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The embodiments of the present application can be variously changed and modified by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
