1. Technical specifications
The length of the basketball stand arm is 3.35m, the upper edge of the basketball hoop is 3.05m above the ground, and the size of the basketball stand box is: length × width × front height × rear height = 2.4 × 1.2 × 0.85 × 0.41 (m). The product meets the technical requirements of the International Basketball Federation. The basketball stand is suitable for a venue (minimum) of 38 meters.
2. Product materials
The base of the basketball stand is welded from 80X120X8mm, 80X120X4mm rectangular tubes and δ10mm steel plates. The front and rear arms are welded from 80X120X4mm rectangular tubes. The arms are welded from 150X150X4mm rectangular tubes and 80X120X3mm rectangular tubes and δ3mm steel plates. The upper pull rod is a φ48X3mm welded pipe, the lock rod is a φ60X6mm seamless pipe, the weld surface is uniform and smooth, the backboard ears are made of precision aluminum alloy, and the die-casting process is adopted, with beautiful appearance and reliable performance.
3. Structural principle
The basketball stand adopts an electric intelligent control system and a hydraulic system. The main body of the basketball stand is lifted by a four-bar linkage. The motor uses a 220V, 50HZ single-phase power supply to drive the oil pump. The microcomputer or remote control system causes the oil cylinder to produce telescopic movement, thereby lifting the basketball stand arm and raising and lowering the box wheel. At the same time, the basketball stand can be remotely controlled to move forward, backward, and turn. There are two universal wheels at the front end of the box and two directional wheels at the rear end.
4. Backboard
The backboard adopts a high-strength safety glass backboard (12mm thick tempered glass), with specifications: 1800×1050 (mm), which has the characteristics of high transparency, good weather resistance, anti-aging, corrosion resistance, and not easy to blur. The tempered glass is affixed with an explosion-proof film to ensure the integrity of the glass after the tempered glass is broken, thereby ensuring the personal safety of the athletes. EVA polyester strips are covered on the bottom edge and sides of the backboard to protect athletes from injury when dunking. The height and thickness of the front and rear surfaces of the protection ring are ≥20mm, and the bottom thickness is ≥50mm. The screw holes on the rubber strip are covered with special plugs, which have a beautiful appearance and protect the athlete's fingers. In accordance with FIBA rules, the backboard elasticity is 500N/min, the center deflection is ≤6mm, and the backboard returns to its original state after the external force is removed for 1min. ★The backboard rubber strip has passed the GB/T10125-2012 salt spray resistance limit test for 1000h, and there is no obvious corrosion on the surface. A test report from a nationally recognized laboratory (providing CNAS and CMA certification of the laboratory) is issued, with a screenshot of the online query attached.
5. Basket
The basket ring is made of φ20mm round steel, with good bending resistance. There is a stamped arc-shaped net hook welded under the ring. The twelve sections are evenly distributed with appropriate gaps. The net is fixed with elastic nylon rope, which is easy to install and replace. When a static load of 105kg is applied to the top of the farthest point of the hoop, the hoop rotates downward at an angle of not less than 10 degrees and not more than 30 degrees, which can ensure the stability of the hoop when the athlete shoots and the safety of the dunk.
6. Fasteners
All fasteners are plated with Dacromet to ensure that they will not rust all year round.
7. Protective measures
The front arm, box, and extension arm of the basketball stand are equipped with special sheaths to effectively protect athletes from impact injuries. The rear is equipped with special counterweights, each with a weight of 480kg, to ensure that the basketball stand does not tip over when a static load of 3200N is applied to the root of the hoop. A special insurance mechanism is installed between the front arm and the extension arm to effectively ensure safety and stability during use.
8. Surface treatment
All steel parts are degreased and physically rust-removed (shot blasting) before being electrostatically sprayed with epoxy powder on the spray line. The coating thickness is 90-110um, and the pencil hardness is 3H+. The product is acid-resistant, heat-resistant, anti-aging, and beautiful in appearance. It is suitable for humid and acid rain environments and does not contain harmful substances.
9. 24-second timer (optional)
The 24-second controller controls the light strip switch, and the light strip is synchronized with the 24-second timer.
