Description

Technical Field

[0001] This utility model relates to the field of sports equipment, and in particular to a highly stable main shaft. Background Technology

[0002] The global basketball hoop market continues to expand, driven by the fitness boom and the growing popularity of basketball. Market demand is strong, particularly for high-quality basketball hoops in commercial real estate, entertainment venues, schools, public parks, and community centers. Furthermore, increasing demand for home entertainment is also fueling the need for basketball hoops from individuals and families. Basketball hoop technology is constantly innovating to meet consumer demand for high-quality, multi-functional products. New basketball hoops are continuously being optimized in terms of design, materials, and functionality.

[0003] Adjustable basketball hoops, adaptable to different user groups, are increasingly favored by consumers. The connection method of the main pole determines its stability. Currently, adjustable main poles suffer from complex structures and high production costs. Some simpler adjustable main poles, however, exhibit poor stability. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model specifically designs a lifting structure and a basketball hoop with the structure.

[0005] The present invention adopts the following technical solution:

[0006] The main rod is highly stable and consists of at least two inner tubes and an outer tube. The inner tubes and the outer tubes are fastened together by a strong clamp. The main rod is a special-shaped rod with a limiting groove. The bottom of the outer tube is equipped with a retaining ring and the top has multiple expansion joints.

[0007] Preferably, the retaining ring has an opening and outward protrusions around its perimeter.

[0008] Preferably, the bottom of the outer tube is provided with a limiting groove that matches the outward protrusion.

[0009] Preferably, the outer tube is further provided with a bushing on the inner side of the top, the bushing is provided with a limiting protrusion, and the outer tube is provided with a limiting hole that matches the limiting protrusion.

[0010] Furthermore, the main rod is composed of a lower rod, a middle lower rod, a middle upper rod, and an upper rod, which are from thickest to thinnest. The bottom of the lower rod, the middle lower rod, and the middle upper rod are all equipped with retaining rings, and multiple expansion joints are opened at the top. The inner side of the top is provided with bushings.

[0011] Meanwhile, this application provides a basketball hoop, including a base, a backboard, and a highly stable main pole as described in any of the preceding claims. The bottom of the main pole is connected to the base, the backboard is fixed to the top of the main pole, and a basket is provided on the backboard.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The protruding feature on the retaining ring extends beyond the outer surface of the tube it is attached to. As the tube moves upward, the movement stops when the upper surface of the protruding feature contacts the bushing mounted on the upper part of the outer tube. Conversely, as the tube moves downward, the movement stops when the lower surface of the tube contacts the retaining ring inside the outer tube. This controls the up-and-down stroke of the main rod system.

[0014] Each tube is a uniquely shaped tube with grooves to prevent relative rotation between tubes. When the desired position is reached, tightening the strong clamps secures the main pole, making the raising and lowering of the main pole reliable and convenient. Attached Figure Description

Detailed Implementation

[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0028] Example 1:

[0029] The main rod is highly stable and comprises at least two inner and outer tubes, which are fastened together by a strong clamp 305. The main rod is a special-shaped rod with a limiting groove. The bottom of the outer tube is equipped with a retaining ring 306, and the top has multiple expansion joints 310. The expansion joints provide space for the strong clamp to tighten.

[0030] The retaining ring has an opening to facilitate installation during production. The retaining ring has outward protrusions around its perimeter, and the bottom of the outer tube has a limiting groove that matches these protrusions. The protrusions engage within the limiting grooves, ensuring that the main rod will not shift upon impact after installation, resulting in high reliability.

[0031] A bushing 307 is also provided on the inner side of the top of the outer tube. The bushing has a limiting protrusion 308, and the outer tube has a limiting hole 309 that matches the limiting protrusion. The limiting protrusion 308 is engaged with the limiting hole to limit the position of the bushing and prevent it from shifting during the raising and lowering of the main rod.

[0032] The bushing is cylindrical with a longitudinal opening in the middle for easy installation during the production process.

[0033] During the production process, the retaining ring and bushing are assembled before leaving the factory, making production and assembly convenient. After assembly, due to the existence of the limiting structure, the reliability is high and the function is stable.

[0034] Example 2:

[0035] The main rod is composed of a lower rod 301, a middle lower rod 302, a middle upper rod 303, and an upper rod, which are arranged from thick to thin. The bottom of the lower rod, the middle lower rod, and the middle upper rod are all equipped with retaining rings, and multiple expansion joints are opened at the top. The inner side of the top is provided with bushings.

[0036] The main rod is an irregularly shaped rod with a limiting groove, and the lower rod, middle lower rod, middle upper rod, and upper rod are fastened together by strong clamps.

[0037] The protruding feature on the retaining ring extends beyond the outer surface of the tube it is attached to. As the tube moves upward, the movement stops when the upper surface of the protruding feature contacts the bushing mounted on the upper part of the outer tube. Conversely, as the tube moves downward, the movement stops when the lower surface of the tube contacts the retaining ring inside the outer tube. This controls the up-and-down stroke of the main rod system.

[0038] Each tube is a specially shaped tube with grooves to prevent relative rotation between tubes. When the tube is moved to the desired position, the strong clamp is tightened to fix the main rod.
