[0003] Generally, the structure of the traditional discus throwing cage net includes a support frame, an isolation net, and a connection between the support frame and the ground. In the previous structure, the support frame is inserted into the ground (holes of appropriate depth are pre-dug on the ground at the boundary of the venue, and then the bottom or end of the support frame is inserted into these holes, and then filled with soil or concrete to fix the support frame. This method is suitable for venues with relatively solid soil) or fixed by anchor bolts or concrete foundations. The above fixing methods have the following defects during use: insufficient stability. When the soil of the venue is unstable or the geological conditions are complex, the fixing method may not provide sufficient stability, which may easily cause the cage net to tilt, shake or collapse, thereby affecting the progress of the game or increasing safety hazards. Difficult maintenance. The unstable soil venue may cause the fixed facilities to be damaged or loose, requiring frequent maintenance and repair, which increases the maintenance cost and workload. The moving cost is high. If the cage net needs to be moved frequently, and the fixing method is not flexible enough, additional manpower and time costs may be required to disassemble, move and reinstall the cage net, increasing the complexity and cost of the operation. Damage to the site. Using a fixed method may require digging or drilling on the surface of the site, which can easily cause damage to the site. Especially when the cage needs to be moved frequently, it may have a greater impact on the site. Utility Model Content
