Description

Technical Field

[0001] The present application relates to the field of sports equipment, and in particular to a support pipe for a portable basketball hoop. Background Art

[0002] A portable basketball hoop consists of a base, a support pipe installed on the base, and a backboard connected to the support pipe.

[0003] The support pipe in the prior art includes a bottom pipe, a middle pipe, and a top pipe that are sequentially connected end to end from bottom to top. On the side wall of the top end of the bottom pipe, several first inner convex points are pressed from outside to inside along its radial direction; on the side wall of the bottom end of the middle pipe, several first inner concave strips corresponding to the several first inner concave points are pressed along its axial direction, and on the side wall of the top end of the middle pipe, several second inner convex points are pressed from outside to inside along its radial direction; on the side wall of the bottom end of the top pipe, several second inner concave strips corresponding to the second inner concave points are pressed from outside to inside along its radial direction; in practice, the bottom pipe and the middle pipe are first placed coaxially, and then the bottom end of the middle pipe is gradually inserted into the top end of the bottom pipe by an external force, so that the first inner convex points on the bottom pipe are embedded into the corresponding first inner concave strips on the middle pipe. Similarly, the bottom end of the top pipe is gradually inserted into the top end of the middle pipe, so that the second inner convex points on the middle pipe are embedded into the corresponding second inner concave strips on the top pipe; in this way, the bottom pipe, the middle pipe, and the top pipe can be sequentially connected end to end.

[0004] In the process of implementing the present application, it is found that the above technology has at least the following problems: The first inner convex points are only embedded into the corresponding first inner concave strips, but do not tightly abut against the outer wall of the middle pipe; similarly, the second inner convex points are only embedded into the corresponding second inner concave strips, but do not tightly abut against the outer wall of the top pipe. In this way, the connection between the bottom pipe and the middle pipe, and between the middle pipe and the top pipe is unstable, resulting in inaccurate positioning problems in the support pipe for the portable basketball hoop. Summary of the Invention

[0005] In order to facilitate the solution of the inaccurate positioning problem existing in the support pipe for the portable basketball hoop, the present application provides a support pipe for a portable basketball hoop.

[0006] The support pipe for a portable basketball hoop provided by the present application adopts the following technical solutions:

[0007] A support pipe for a portable basketball hoop includes several sequentially connected connecting pipes. A convex rib is provided on the side wall of one end of the connecting pipe, and a positioning notch is opened at the pipe orifice of the other end of the connecting pipe. The positioning notch on the connecting pipe is used for the convex rib on another connecting pipe connected thereto to be embedded, and the convex rib on another connecting pipe abuts against the inner wall of the connecting pipe; a limiting strip-shaped groove for the convex rib on another connecting pipe to extend into is opened on the inner wall of the connecting pipe, and a first limiting ring abutting against another connecting pipe is connected.

[0008] By adopting the above technical solution, first, the rib on one connecting pipe is inserted into the positioning slot on the other connecting pipe, and then the rib is gradually deformed by an external force and extends into the other connecting pipe. After the rib enters the other connecting pipe, it immediately extends into the limiting strip-shaped groove, and then continues to move into the connecting pipe along the limiting strip-shaped groove until the end of the connecting pipe where the rib is located abuts against the first limiting ring in the other connecting pipe, and after the rib enters the other connecting pipe, it always tightly abuts against the inner wall of the other connecting pipe; on the premise that the rib tightly abuts against the inner wall of the connecting pipe, the rib is also limited in the circumferential direction of the connecting pipe by the limiting strip-shaped groove to prevent the two connected connecting pipes from rotating relative to each other. In addition, the connecting pipes are limited in the axial direction by the first limiting ring, so as to facilitate solving the problem of inaccurate positioning in the support pipes of the portable basketball hoop.

[0009] In a specific feasible implementation, an anti-vibration ring is provided on the outer wall of the connecting pipe, and the anti-vibration ring is used to abut against the inner wall of the other connecting pipe.

[0010] By adopting the above technical solution, the anti-vibration ring and the rib connected to a certain connecting pipe jointly abut against the inner wall of the other connecting pipe, so as to facilitate preventing the connecting pipe from shaking in the other connecting pipe.

[0011] In a specific feasible implementation, a hook is hinged on the first limiting ring, and a return spring connected to the hook; a ring groove for the hook to be inserted into is provided on the connecting pipe.

[0012] By adopting the above technical solution, the hook on one connecting pipe is inserted into the ring groove on the other connecting pipe, so as to facilitate preventing the connecting pipe from detaching from the other connecting pipe on the premise that it has been positioned in the other connecting pipe.

[0013] In a specific feasible implementation, a guiding surface is provided at the end of the connecting pipe extending into the other connecting pipe, and the guiding surface is used for sliding connection with the hook.

[0014] By adopting the above technical solution, during the process of one connecting pipe extending into the other connecting pipe, the guiding surface on the connecting pipe gradually spreads open the hook through the guiding surface, so that the hook can easily enter the ring groove.

[0015] In a specific feasible implementation, a driving assembly is provided in the connecting pipe, and the driving assembly is used to drive the hook to rotate.

[0016] By adopting the above technical solution, when it is necessary to separate the two connected connecting pipes at both ends, the driving assembly can be used to drive the hook to rotate, so that the hook disengages from the ring groove, so as to facilitate the separation between the two connecting pipes.

[0017] In a specific feasible embodiment, the driving component includes a motor connected in the connecting pipe, a driving rod is connected to the output shaft of the motor, and the driving rod is connected to the hook.

[0018] By adopting the above technical solution, the driving rod is driven to rotate by the motor, so that the driving rod drives the hook to rotate, thus facilitating the purpose of disengaging the hook from the annular groove.

[0019] In a specific feasible embodiment, a placement groove is formed on the outer side wall of the connecting pipe, a control switch is arranged in the placement groove, and the control switch is electrically connected to the motor; a groove cover for closing the placement groove is further arranged on the side wall of the connecting pipe.

[0020] By adopting the above technical solution, the control switch is arranged on the outer side wall of the connecting pipe, so that it is convenient for people to drive the motor to operate from the outside of the connecting pipe, thereby realizing the rotation of the hook.

[0021] In a specific feasible embodiment, a second limiting ring is arranged on the side wall of the connecting pipe, and the second limiting ring is used for abutting against another connecting pipe.

[0022] By adopting the above technical solution, the second limiting ring on one connecting pipe abuts against another connecting pipe, so as to further prevent the two connecting pipes from moving relatively in the axial direction of the connecting pipe.

[0023] In a specific feasible embodiment, a sealing ring gasket is arranged on the second limiting ring, and the sealing ring gasket is used for abutting against another connecting pipe.

[0024] By adopting the above technical solution, it is convenient to prevent foreign matters such as dust from entering the gap between the two connecting pipes through the sealing ring gasket.

[0025] In a specific feasible embodiment, a plurality of reinforcing ribs are arranged in the connecting pipe, the plurality of reinforcing ribs are distributed along the axial direction of the connecting pipe, and a reinforcing rod is commonly connected to the plurality of reinforcing ribs.

[0026] By adopting the above technical solution, the structural strength of the connecting pipe is facilitated by the reinforcing ribs and the reinforcing rod.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. Solve the problem of inaccurate positioning in the support pipe of the portable basketball hoop;

[0029] 2. Facilitate preventing the connected connecting pipes from separating from each other through the hook;

Detailed implementation manners

[0037] The following further elaborates on the present application in conjunction with the attached Figures 1-5 for a more detailed description.

[0038] The embodiment of the present application discloses a support pipe for a portable basketball hoop. Referring to Figure 1 , the support pipe for a portable basketball hoop includes not less than two coaxially arranged and sequentially connected connecting pipes; since the connection methods between two mutually connected connecting pipes are all the same, for the sake of avoiding repetition, in the following, two mutually connected connecting pipes are taken as an example to illustrate the connection method between the connecting pipes, and these two connecting pipes are respectively denoted as the first connecting pipe 1 and the second connecting pipe 2.

[0039] Referring to Figure 2, the first connecting pipe 1 includes a first pipe body 11. A plurality of convex ribs are provided on the side wall at one end of the first pipe body 11, and the plurality of convex ribs are distributed equidistantly and at equal angles around the central axis of the first pipe body 11. For the convenience of description, the convex ribs on the first pipe body 11 are denoted as the first convex ribs 12; combined with Figure 1 , a positioning notch corresponding to the position of the first convex rib 12 is provided at the end of the first pipe body 11 away from the convex rib. For the convenience of description, the positioning notch on the first pipe body 11 is denoted as the first positioning notch 111; it should be noted that the connection line between the first convex rib 12 and the corresponding first positioning notch 111 is parallel to the central axis of the first pipe body 11.

[0040] Refer to Figure 2 , the second connecting pipe 2 includes a second pipe body 21. A positioning notch corresponding to the first convex rib 12 is provided at one end of the second pipe body 21, and the positioning notch on the second pipe body 21 is denoted as the second positioning notch 211; combined with Figure 1 , a second convex rib 22 corresponding to the position of the second positioning notch 211 is provided on the side wall at the end of the second pipe body 21 away from the second positioning notch 211. It should be noted that the connection line between the second convex rib 22 and the corresponding second positioning notch 211 is parallel to the central axis of the second pipe body 21; the width of the first convex rib 12 is the same as the width of the second positioning notch 211; the outer diameter of the first pipe body 11 is smaller than the inner diameter of the second pipe body 21; the distance from the central axis of the first pipe body 11 to the top of the first convex rib 12 is greater than the inner diameter of the second pipe body 21.

[0041] In implementation, refer to Figure 3 , first align the first convex rib 12 with the corresponding second positioning notch 211, and then gradually insert the end of the first pipe body 11 with the first convex rib 12 into the first pipe opening, so that the first convex rib 12 gradually enters the corresponding second positioning notch 211. At this time, the first convex rib 12 and the side wall of the second positioning notch 211 are in a sliding connection state. In this way, the second positioning notch 211 can play a role in limiting and guiding the first convex rib 12, that is, play a role in limiting and guiding the first pipe body 11.

[0042] Refer to Figure 3 , the first convex rib 12 is integrally formed on the first pipe body 11 by two inclined plates, and the inclined plate closer to the bottom of the second positioning notch 211 is denoted as the first inclined plate 121; when the first convex rib 12 moves to the bottom of the second positioning notch 211, the connection between the first inclined plate 121 and the first pipe body 11 abuts against the bottom of the second positioning notch 211; at this time, then move the first pipe body 11 towards the inside of the first pipe body 11. In this way, the inner wall of the second pipe body 21 also gradually presses against the first convex rib 12, so that the first convex rib 12 gradually deforms until the first convex rib 12 enters the second pipe body 21.

[0043] Refer to Figure 4, To prevent the first tube body 11 from rotating during the process of entering the second tube body 21, a limiting strip-shaped groove 213 corresponding to the first convex rib 12 one by one and into which the deformed first convex rib 12 extends is provided on the inner wall of the second tube body 21. The length direction of the limiting strip-shaped groove 213 is consistent with the axial direction of the second tube body 21, and the width of the limiting strip-shaped groove 213 is the same as the width of the first convex rib 12. In this way, after the deformed first convex rib 12 enters the second tube body 21, it can only move along the length direction of the limiting strip-shaped groove 213 and cannot rotate circumferentially. Thus, it is convenient to improve the stability of the process of the first tube body 11 entering the second tube body 21.

[0044] To prevent the first tube body 11 from extending too far into the second tube body 21, a first limiting ring 23 is fixed on the inner wall of the second tube body 21. The first limiting ring 23 is coaxially arranged with the second tube body 21. The first limiting ring 23 is arranged at one end of the limiting strip-shaped groove 213 inside the second tube body 21, and the first limiting ring 23 is used to abut against one end of the first tube body 11 extending into the second tube body 21. To enhance the stability when the first limiting ring 23 abuts against the first tube body 11, a first reinforcing ring 24 fixed to the inner wall of the second tube body 21 is connected to the side of the first limiting ring 23 away from the first tube body 11.

[0045] To further prevent the first tube body 11 from extending too far into the second tube body 21, a second limiting ring 13 is fixed on the side wall of the first tube body 11. The second limiting ring 13 is coaxially arranged with the first tube body 11, and the first limiting ring 23 is used to abut against the end of the second tube body 21. To enhance the stability when the second limiting ring 13 abuts against the second tube body 21, a second reinforcing ring 14 fixed to the inner wall of the first tube body 11 is connected to the side of the second limiting ring 13 away from the second tube body 21.

[0046] To prevent foreign matters such as dust from entering the gap between the first tube body 11 and the second tube body 21, a sealing ring gasket 15 is fixed on the side wall of the second limiting ring 13 close to the second tube body 21. The sealing ring gasket 15 is coaxially arranged with the second limiting ring 13 and is used to abut against the end of the second tube body 21.

[0047] To prevent the first tube body 11 from shaking after extending into the second tube body 21, refer to Figure 5 , A anti-shaking ring 16 is coaxially fixed on the side wall of one end of the first tube body 11 extending into the second tube body 21. The outer side wall of the anti-shaking ring 16 abuts against the inner wall of the second tube body 21.

[0048] To prevent the first tube body 11 that has extended into the second tube body 21 from detaching from the second tube body 21, a clamping component 25 for clamping the first tube body 11 is further provided on the second tube body 21. It should be noted that refer to Figure 5, a ring groove 112 is provided on the side wall of one end of the first pipe body 11 extending into the second pipe body 21; specifically, the clamping component 25 includes two hooks 251 hinged on the first limiting ring 23, and a reset spring 252 corresponding to each hook 251 is provided on the first limiting ring 23. The reset spring 252 is used to make the hook part of the hook 251 move towards the inner wall of the second pipe body 21; thus, when the end of the first pipe body 11 with the ring groove 112 extends into the second pipe body 21 and abuts against the hook 251, it can drive the hook part of the hook 251 to move away from the inner wall of the second pipe body 21 until the hook part of the hook 251 is clamped into the ring groove 112 under the action of the spring.

[0049] In order to facilitate the hook 251 to more easily enter the ring groove 112 during the process of abutting against the end of the first pipe body 11, a facilitating surface 113 slidably connected to the hook 251 is provided on the end of the first pipe body 11 extending into the second pipe body 21. The facilitating surface 113 is used to abut against the hook 251 to make the hook 251 move away from the inner wall of the second pipe body 21, so as to facilitate the hook 251 to slide into the ring groove 112 during the process of sliding connection with the facilitating surface 113.

[0050] In order to facilitate the separation of the first pipe body 11 from the second pipe body 21 when it is necessary to separate the first pipe body 11 from the second pipe body 21, a driving component 26 is provided on the second pipe body 21. Specifically, the driving component 26 includes a motor 261 fixed on the inner wall of the second pipe body 21. A rotating disk 262 is coaxially fixed on the output shaft of the motor 261. Two fixing rods 263 are fixed on the edge of the rotating disk 262. The two fixing rods 263 correspond to the two hooks 251 one by one. The two fixing rods 263 are symmetrically arranged with the center of the rotating disk 262 as the center, and the two fixing rods 263 are also arranged along the radial direction of the rotating disk 262; one end of each fixing rod 263 away from the rotating disk 262 is hinged with a connecting rod 264, and one end of each connecting rod 264 away from the corresponding fixing rod 263 is hinged with the tail of the corresponding hook 251; a control switch 265 electrically connected to the motor 261 is also provided on the second pipe body 21.

[0051] In order to facilitate manual operation of the control switch 265 and prevent the control switch 265 from being affected by the external environment, a placement groove 212 is provided on the outer side wall of the second pipe body 21. The control switch 265 is installed in the placement groove 212, and a groove cover 27 for closing the placement groove 212 is hinged on the outer wall of the second pipe body 21.

[0052] Refer to Figure 4, in order to facilitate strengthening the structural strength of the first pipe body 11 and the second pipe body 21, a number of reinforcing ribs 3 are provided in the first pipe body 11 and the second pipe body 21 along their radial directions. The reinforcing ribs 3 are distributed along the axial direction of the first pipe body 11 and the second pipe body 21, and a reinforcing rod 4 is commonly connected at the centers of the number of reinforcing ribs 3.

[0053] It should be noted that the above only introduces two of the connecting pipes that make up the support pipe for the portable basketball hoop, as well as the connection structure and connection method between these two connecting pipes. The remaining connecting pipes that make up the support pipe for the portable basketball hoop also adopt the above connection structure and connection method.

[0054] The above are all preferred embodiments of the present application. Without restricting the protection scope of the present application based on this, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
