[0002] A tent is a shelter erected on the ground to protect against wind, rain, and sunlight, and to provide temporary shelter. It is an indispensable piece of equipment for outdoor activities and emergencies, providing people with temporary shelter and protection from the elements. Tents are widely used not only in outdoor camping but also play a vital role in emergencies. For example, during natural disasters or war, tents can serve as temporary refuges, providing people with a safe place to live. Furthermore, inflatable construction tents are widely used on construction sites to provide temporary work or living spaces.

[0003] Tent frames are structures used to support the tent fabric and prevent the tent from collapsing. However, existing tent frames lack sufficient stability, are cumbersome to assemble and disassemble, and cannot guarantee the safety of the tent in various outdoor situations, making them inconvenient to use.

[0004] Therefore, a stable tent frame that can enhance stability and is easy to assemble and disassemble is needed. Utility Model Content

Example 1

[0021] Reference Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 8 As shown, specifically, a stable tent support includes connecting plates 1. Two connecting plates 1 can connect two C-shaped frames 2 together. Connecting grooves 11 are symmetrically provided at the ends of the connecting plates 1 for accommodating the C-shaped frames 2. A connecting shaft 111 is fixed to the inner wall of the connecting groove 11 to connect the C-shaped frames 2. The C-shaped frames 2 are movably sleeved on the outer side of the connecting shaft 111 to support the support tube 3. Rotating holes 22 are symmetrically provided at the ends of the C-shaped frames 2, allowing the C-shaped frames 2 to rotate about the connecting shaft 111. The connecting shaft 111 is movably sleeved inside the rotating hole 22. A moving groove 12 is provided in the middle of the inner wall of one side of the connecting groove 11 for moving a limiting plate 13. A control groove 121 is provided on the top surface of the inner side of the moving groove 12 for moving a control plate 131. A limiting plate 13 is movably inserted into the inner side of the moving groove 12 to restrict the rotation of the C-shaped frames 2. A control plate 131 is fixed to the edge of the frame for manually controlling the movement of the limiting plate 13. The control plate 131 passes through the control groove 121. A spring 132 is fixed to one end of the limiting plate 13, which can push the limiting plate 13 to move through the elastic force. The spring 132 is located inside the moving groove 12, and one end of the spring 132 is fixed to the inner wall of the moving groove 12. The inner wall of the rotating hole 22 is provided with a limiting groove 221. The other end of the limiting plate 13 is movably inserted into the inner side of the limiting groove 221 to fix the C-shaped frame 2. In this solution, the elastic force of the spring 132 pushes the limiting plate 13 to insert into the inner side of the limiting groove 221, thereby fixing the C-shaped frame 2. By moving the control plate 131, the limiting plate 13 can be manually moved out of the inner side of the limiting groove 221, so that the C-shaped frame 2 can rotate. The two C-shaped frames 2 can be folded together by rotating relative to each other, thereby reducing space occupation and facilitating transportation and carrying. Example 2

[0022] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9As shown, specifically, a fixing cylinder 21 is symmetrically fixed on the top surface of the C-frame 2, connecting to the support tube 3. The support tube 3 is movably inserted into the inner side of the fixing cylinder 21, providing support for the U-frame 4. An insertion cylinder 31 is fixed to the upper outer wall of the support tube 3 for connecting the insertion rod 5. The insertion rod 5 is movably inserted into the inner side of the insertion cylinder 31, reinforcing the structure. The U-frame 4 is movably inserted into the upper inner side of the support tube 3, supporting the tent fabric. The outer wall of the U-frame 4 has a rectangular hole 41 for connecting the support plate 6. The support plate 6 is movably inserted into the inner side of the rectangular hole 41, preventing the upper end of the tent fabric from denting. The connecting plate 1, C-frame 2, support tube 3, and U-frame 4 of this solution form a complete tent frame. The support plate 6 and insertion rod 5 strengthen the overall structure, increasing stability and making it easy to assemble and disassemble, facilitating outdoor use. Example 3

[0023] In another embodiment of this solution, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, specifically, a first threaded cylinder 211 is fixed to the upper outer wall of the fixed cylinder 21 for connecting the first screw 212. The first threaded cylinder 211 is connected to the inner side of the fixed cylinder 21, and the first screw 212 is threadedly connected to the inner side of the first threaded cylinder 211, which can fix the support tube 3. A second threaded cylinder 32 is fixed to the upper outer wall of the support tube 3 for connecting the second screw 321. The second threaded cylinder 32 is connected to the inner side of the support tube 3, and the second screw 321 is threadedly connected to the inner side of the second threaded cylinder 32, which can fix the support tube 3. The U-shaped frame 4 is limited in position. A third threaded cylinder 42 is fixed to the outer wall of the U-shaped frame 4 for connecting the third screw 421. The third threaded cylinder 42 is connected to the inner side of the rectangular hole 41. The third screw 421 is threaded to the inner side of the third threaded cylinder 42 to fix the support plate 6. In this solution, the first screw 212 is used to fix the support tube 3, the second screw 321 is used to fix the U-shaped frame 4, and the third screw 421 is used to fix the support plate 6. The structure is simple, the stability is good, and the operation is convenient. Disassembly only requires turning the screw.

[0024] The working principle and usage process of this utility model: In use, the tent fabric is supported by two connecting plates 1, two C-shaped frames 2, four support tubes 3, and two U-shaped frames 4. Support plate 6 at the top prevents the tent fabric from collapsing, and two plug-in rods 5 reinforce the structure on both sides. One end of the first screw 212 abuts against the support tube 3 for positioning, one end of the second screw 321 abuts against the U-shaped frame 4 to prevent movement, and the third screw 421 abuts against the support plate 6 from below for fixation. To disassemble, the third screw 421 is turned down to remove it from contact with the support plate 6, allowing the support plate 6 to be removed from the rectangular hole 41. Pull out the U-shaped frame 4, then turn the second screw 321 so that it is no longer in contact with the U-shaped frame 4. Pull the U-shaped frame 4 out from the inside of the support tube 3. Then turn the first screw 212 so that it is no longer in contact with the support tube 3. Pull the support tube 3 out from the inside of the fixing cylinder 21. Then pull the plug rod 5 out from the inside of the plug cylinder 31. Finally, control the limit plate 13 to move out of the limit groove 221 by moving the control plate 131. Then flip the C-shaped frame 2 upwards and flip the two C-shaped frames 2 so that the two C-shaped frames 2 can be folded and stored. The disassembly process is completed. It is very simple and convenient.
