It can automatically adjust the height of the net and, through a photoelectric switch, precisely position the net height, ensuring it strictly conforms to the rules of the game and guaranteeing fairness and standardization. However, this patent still has the following problems in practical use: Although this type of volleyball and badminton dual-purpose net post can accurately position the net height through the setting of photoelectric switches, ensuring that the net height strictly conforms to the competition rules, it is not convenient for net storage, and its production and maintenance costs are relatively high. Volleyballs are often used outdoors or in stadiums, and dust, cobwebs, etc. may block the photoelectric sensor, affecting accuracy.

[0004] A multifunctional air volleyball column is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional air volleyball column to solve the problems mentioned in the background art.

[0012] Preferably, an elongated strip is provided directly below the J-shaped hook, and the bottom of the elongated strip is fixedly connected to the concave frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this multifunctional volleyball column, by setting a self-locking mechanism, enables the quick disassembly and assembly of the cover plate, thereby facilitating the removal of the counterweight and the net; by setting a lifting mechanism, the height of the volleyball column can be manually adjusted, thus reducing the manufacturing cost of the product. The specific details are as follows: 1. The self-locking mechanism enables quick assembly and disassembly of the cover plate, facilitating the removal of the counterweight and net. The engagement between the protrusion and the base box allows for quick installation of the cover plate. Pressing the button lever moves the cylinder within the slide groove, while the pin limits the connecting frame, causing the protrusion to retract into the groove and releasing the protrusion's restriction on the base box, thus enabling quick disassembly of the cover plate. 2. By setting up a lifting mechanism, the height of the air volley column can be manually adjusted, which can reduce the manufacturing cost of the product. By pulling the support rod upward, the sawtooth block can be driven to rotate around the support rod. At the same time, the reaction force after the second spring is compressed can ensure that the sawtooth block and the sawtooth strip are always in a meshing state, thus changing the height of the air volley column, thereby adapting to different usage scenarios and improving the practicality of the device.

There are four pins 103, and the pins 103 are evenly distributed at the top corner of the cover plate 102. The base box 101 is hollow, and counterweights of different materials can be added according to the size of the base box 101, which facilitates the storage of the ball net. By setting four pins 103, two people need to press the button rod at the same time to open the cover plate 102, so it has a certain anti-theft effect when the user is unaware. A groove 104 is provided at the center of the bottom side inside the pin 103. A protrusion 105 is slidably connected inside the groove 104. The outer side of one end of the protrusion 105 is engaged with the base box 101. A corresponding slot is provided near the protrusion 105 in the base box 101. A groove 106 is provided at the center of the protrusion 105. A cylinder 107 is slidably connected inside the groove 106. A connecting bracket 108 is sleeved on the outer side of both ends of the cylinder 107. The outer side of the connecting bracket 108 is slidably connected to the pin 103. A slot is provided near the connecting bracket 108 in the pin 103 to restrict the connecting bracket 108 from moving left and right inside the pin 103. A button rod 109 is fixedly connected to the top of the connecting bracket 108. The outer side of the button rod 109 is slidably connected to the pin 103. One side of the button rod 109 is fixedly connected to the first spring 110. The end of the first spring 110 away from the button rod 109 is fixedly connected to the pin 103. By setting the first spring 110, the button rod 109 and the protrusion 105 can be automatically reset. The lifting mechanism 2 includes a concave frame 201. The bottom of the concave frame 201 is fixedly connected to the base box 101. Sawtooth strips 202 are symmetrically fixedly connected to both sides of the inner wall of the concave frame 201. A limiting groove 203 is opened on the side of the concave frame 201 near the sawtooth strips 202. A slide bar 204 is slidably connected inside the limiting groove 203. The sawtooth shape at the top of the sawtooth strip 202 is larger than the sawtooth shape below. A support rod 205 is fixedly connected to the top of the slide bar 204. The outer side of the support rod 205 is slidably connected to the concave frame 201. The top of the support rod 205 is fixedly connected to the guide structure 206. A tightening wheel 207 is fixedly connected to one side of the bottom of the support rod 205. The tightening wheel 207 is located below the guide structure 206. A connecting seat 208 is fixedly connected to the side of the support rod 205 away from the tensioning wheel 207. Second springs 209 are fixedly connected symmetrically on the left and right sides of the connecting seat 208. A sawtooth block 210 is fixedly connected to the end of the two second springs 209 away from the connecting seat 208. The reaction force after the second springs 209 are compressed can ensure that the sawtooth block 210 and the sawtooth strip 202 are always in a meshing state. The end of the serrated block 210 near the second spring 209 is rotatably connected to the support rod 205. The side of the serrated block 210 away from the second spring 209 is attached to the serrated strip 202. A limit post 211 is fixedly connected to the outer side of the end of the serrated block 210 away from the second spring 209. A J-shaped hook 212 is provided on one side of the limit post 211. A torsion spring post is provided on the outer side of the end of the J-shaped hook 212 away from the limit post 211. The torsion spring post is fixedly connected to the support rod 205. Moreover, the torsion spring post can keep the J-shaped hook 212 in a horizontal state when it is not subjected to external force. A long strip 213 is provided directly below the J-shaped hook 212. The bottom of the long strip 213 is fixedly connected to the concave frame 201. When the support rod 205 is lowered to the lowest end, the J-shaped hook 212 can be separated from the limiting post 211 by the action of the long strip 213 on the J-shaped hook 212.

[0018] Working principle: Before using this multi-functional air volleyball column, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 13As shown, when the net needs to be removed from the base box 101, press the button lever 109 to move the cylinder 107 in the slide groove 106. At the same time, the pin 103 limits the connecting bracket 108, which can retract the protrusion 105 into the groove 104, thereby releasing the protrusion 104 from limiting the base box 101, and thus enabling the cover plate 102 to be quickly disassembled. Secondly, the two ends of the net are placed on the outside of the support rod 205, and the nylon rope at the end is passed through the guide structure 206 and wrapped around the surface of the tensioning wheel 207. The net can be taut by rotating the tensioning wheel 207. Then, pulling the support rod 205 upwards can cause the sawtooth block 210 to rotate around the support rod 205. At the same time, the reaction force after the second spring 209 is compressed can ensure that the sawtooth block 210 and the sawtooth strip 202 are always in a meshing state, which can change the height of the air volley column. Finally, when it is necessary to lower the height of the air volley column, first move the support rod 205 to its highest position, then use the large serrations at the highest point of the serrated bar 202 to drive the serrated block 210 to rotate and move to the inside of the J-shaped hook 212. By utilizing the cooperation between the J-shaped hook 212 and the limiting post 211, the serrated block 210 can be separated from the serrated bar 202. Gravity can then be used to lower the support rod 205. When the support rod 205 reaches its lowest point, the action of the elongated bar 213 on the J-shaped hook 212 can be used to separate the J-shaped hook 212 from the limiting post 211. At the same time, the reaction force after the second spring 209 is compressed can ensure that the serrated block 210 and the serrated bar 202 are in an engaged state to ensure the subsequent use of the device.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
