Detailed Implementation

[0023] Please see Figures 1-4 A portable badminton net stand, comprising:

[0024] The base assembly includes a pair of bases 2 arranged symmetrically on the left and right sides of the upper end of the base 2. Each base 2 has a socket 4 fixedly connected to its upper end, and a slot is formed at the upper end of the socket 4. A rubber coating is fixed to the outer side of the lower part of each pin 5. The pin 5 is inserted into the slot and has an interference fit with the slot. Two badminton players can pull the two bases 2 separately to create a gap between them, allowing the pin 5 to be inserted into the socket 4 of the base 2, thus achieving an interference fit between the pin 5 and the slot.

[0025] The telescopic frame 9 is rotatably connected inside the hinge seat 6. The telescopic frame 9 includes a sleeve 91, a pin 92, and a slide rod 93. Rotating shafts 8 are fixed to the lower left and right sides of the sleeve 91. The ends of the rotating shafts 8 pass through the hinge seat 6 and are rotatably connected to it. The slide rod 93 is slidably connected inside the sleeve 91. Limiting strips 94 are fixed to both ends of the slide rod 93. Limiting grooves are formed at both ends of the inner wall of the sleeve 91. The limiting strips 94 are located inside the limiting grooves and are slidably connected to them. Insertion holes 95 are formed on both the upper and lower sides of the surface of the limiting strip 94. The two insertion holes 95 on the same horizontal line are connected. The pin 92 movably passes through the upper part of the sleeve 91 and is inserted into the insertion holes 95. After inserting the pin 5 into the insertion seat 4 of the base 2, the telescopic frame 9 and the base assembly are completed. The assembly is as follows: by pulling out the pin 92, the slide bar 93 can be slid up and down, causing the telescopic frame 9 to extend and retract. After the telescopic frame 9 is extended, the lower insertion hole 95 corresponds to the pin 92, and then the pin 92 can be inserted so that it passes through the insertion hole 95 to limit the slide bar 93. After the telescopic frame 9 is shortened, the upper insertion hole 95 corresponds to the pin 92, and then the pin 92 can be inserted so that it passes through the insertion hole 95 to limit the slide bar 93. When it is not necessary to disassemble the telescopic frame 9 from the base assembly for easy carrying, the vertical telescopic frame 9 can be rotated backward to be horizontal. In this way, the sleeve 91 rotates through the pivot 8 and the hinge seat 6 on the insertion post 5. The hinge seat 6 is U-shaped and has a stop at the front and upper part to ensure that when the sleeve 91 is rotated to the vertical state, the front part of the sleeve 91 abuts against the stop to ensure that the sleeve 91 is vertical.

[0026] The take-up roller 10 is movably sleeved on the upper side of one of the telescopic frames 9 and is movably sleeved on the outside of one of the slide bars 93. The take-up roller 10 is located above the limiting bar 94 and can rotate on the upper part of the slide bar 93 of one of the telescopic frames 9.

[0027] A barrier net 11 is wound around the outside of the take-up roller 10. The end of the barrier net 11 is fixed to another telescopic frame 9 and another slide rod 93. The beginning of the barrier net 11 is wound around the outside of the take-up roller 10. In this way, when the distance between the bases 2 is widened, the barrier net 11 can be unwound and extended from the outside of the take-up roller 10. When the distance between the bases 2 is narrowed, the barrier net 11 can be wound around the outside of the take-up roller 10 by rotating the take-up roller 10.

[0028] The self-locking assembly 7 is mounted on the side of the hinge seat 6 and connected to the telescopic frame 9. The self-locking assembly 7 includes a ratchet box 71, a ratchet 72, a pawl 73, and a U-shaped spring plate 74. The ratchet box 71 is fixed to the hinge seat 6. The end of the rotating shaft 8 extends into the ratchet box 71. The ratchet 72 is fixed to the end of the rotating shaft 8. The pawl 73 is located above the ratchet 72 and rotatably connected inside the ratchet box 71. The U-shaped spring plate 74 is fixed to the top of the ratchet box 71, with its lower part closely abutting the pawl 73. A pressure rod 75 is fixedly connected to the rear of the pawl 73. A slide rail 76 is provided at the upper end of the ratchet box 71, and the upper part of the pressure rod 75 extends outwards... When the telescopic frame 9 is rotated from a vertical to a horizontal position, the rotating shaft 8 needs to rotate clockwise. At this time, pressing the pressure rod 75 causes the pawl 73 to rotate and separate from the ratchet 72. The pawl 73 then squeezes the U-shaped spring plate 74, allowing the ratchet 72 to rotate clockwise. This prevents the telescopic frame 9 from rotating automatically when it is in a vertical position. When it is necessary to rotate the horizontal telescopic frame 9 to a vertical position, the rotating shaft 8 will rotate counterclockwise. This causes the ratchet 72 to rotate counterclockwise, and the pawl 73 will not obstruct the ratchet 72 from rotating counterclockwise. This ensures that the vertical telescopic frame 9 is self-locking after being rotated from a horizontal to a vertical position, making it convenient to use.

[0029] The lower end of the base 2 is fixedly connected to a wear-resistant pad 3. When two people pull the distance between the base 2 apart or closer together, the wear-resistant pad 3 can prevent the ground from directly abrading the base 2.

[0030] Working principle: During use, two badminton players pull the two bases 2 respectively, widening the gap between them and moving the bases 2 outside the white lines of the badminton court. Then, they pull open the telescopic frame 9. During this process, the net 11 extends and unwinds from the outside of the take-up roller 10, inserting the pin 5 into the insertion seat 4 of the base 2, so that the pin 5 and the slot are interference-fitted, completing the assembly of the telescopic frame 9 and the base assembly. Then, the pin 92 is pulled out, so that the pin 92 is pulled out from the upper insertion hole 95. The slide bar 93 is slid upwards, so that the telescopic frame 9 extends, and the lower insertion hole 95 aligns with the pin 92. Then, the pin 92 can be inserted, so that the pin 92 passes through the insertion hole 95 to limit the slide bar 93. After that, badminton can be played. After playing badminton, the pin 92 is first pulled out from the lower insertion hole 95, and then the telescopic frame 9 is shortened, so that the upper insertion hole 95 aligns with the pin 92. Then, the pin 92 can be inserted, so that the pin 92 passes through the insertion hole 95 to limit the slide bar 93. Pin 92 passes through insertion hole 95 to limit slide bar 93. Then, the two bases 2 are pulled closer together. Then, the net 11 is rolled up outside the take-up roller 10 by rotating the take-up roller 10. Alternatively, without disassembling the telescopic frame 9 and base assembly, the telescopic frame 9 can be rotated from a vertical state to a horizontal state and placed in the trunk of a car. During this process, the pressure rod 75 needs to be pressed. The pressure rod 75 drives the pawl 73 to rotate and separate from the ratchet 72. The pawl 73 then squeezes the U-shaped spring plate 74, at which point the ratchet 72 can rotate clockwise. The pawl 73 is used to prevent the ratchet 72 from rotating clockwise, thus preventing the telescopic frame 9 from automatically rotating to a horizontal state when it is in a vertical state. This makes it convenient to put the entire portable badminton net frame in the trunk of a car. When you need to play badminton, you can take it out, set it up and use it. This makes it simple to operate and easy to carry, ensuring that playing badminton is not limited by the venue, which is conducive to the healthy development of badminton.
