Description

Technical Field

[0001] The invention relates to the technical field of outdoor tents, in particular to an outdoor tent support frame. Background Art

[0002] The outdoor tent support frame is a key structural component of the tent, and plays a vital role in the stability and reliability of the tent. It is usually made of high-strength lightweight materials, such as aluminum alloy or carbon fiber, to reduce the overall weight while ensuring strength, making it easy to carry and set up. The support frame is exquisitely designed and adopts a foldable or detachable structure for easy storage and transportation. When setting up the tent, the support frame provides a stable support for the tent through a reasonable structure and connection method. Its shape and size are carefully calculated to adapt to tents of different types and sizes, ensuring that the tent can effectively withstand wind, rain and external pressure. For example, in a strong wind environment, a sturdy support frame can keep the tent stable and provide a safe shelter for the user. Moreover, a high-quality support frame also has good corrosion resistance and durability, and can withstand the test of various outdoor environments. In short, the outdoor tent support frame is an indispensable and important component in outdoor camping, providing reliable protection for people to rest in nature;

[0003] When installing an outdoor tent, the brackets need to be spliced ​​together; however, the installation process of the brackets on the market is cumbersome and cannot achieve the effect of easy installation. Summary of the invention

[0005] The upper surface of the first connecting frame is fixedly connected with an unfolding mechanism. By setting the first connecting frame, when the top end of the movable rod moves up and down, the unfolding mechanism can also be driven to move up and down. The unfolding mechanism includes an arc tube. By setting the unfolding mechanism, the two top plates can be squeezed, and during the squeezing process, the angle between the two top plates can be changed, thereby supporting the top of the outdoor tent, so that the outdoor tent can be unfolded. The arc tube is fixedly connected to the top of the first connecting frame, and the upper surface of the arc tube is fixedly connected to the second connecting frame. The top of the second connecting frame is fixedly connected to a limiting rod, and the outer surface of the limiting rod is rotatably connected with a rotating ring, and the outer surface of the rotating ring is fixedly connected with the top plate. By setting the arc tube, the second connecting frame can be connected to the first connecting frame and the arc rod can be limited at the same time. By setting the limiting rod, the rotating ring can be limited so that the rotating ring can rotate at the end of the limiting rod, thereby enabling the two top plates to stably rotate with the limiting rod as the center of the circle, which is convenient for unfolding the outdoor tent.

By setting the trigger mechanism, when the distance between the unfolding mechanism and the bottom plate changes, the sliding block in the unfolding mechanism can be squeezed, thereby causing the sliding block and the arc rod to slide, and finally the two top plates can rotate with the limiting rod as the center.

[0007] Preferably, there are two limiting tubes, and movable rods are slidably connected to the inner cavities of the two limiting tubes. By providing two limiting tubes, the supporting strength of the first connecting frame can be increased to prevent the tent from shaking during the unfolding process.

By setting the arc rod, the arc rod can be driven to move together during the sliding of the sliding block in the inner cavity of the arc tube, thereby causing the fixed block and the first limiting ring at the end to move. By setting the first limiting ring, the first rotating block can be limited, so that the first rotating block can generate stable rotation in the inner cavity of the first limiting ring.

[0017] 2. The outdoor tent support frame can squeeze the two top plates by setting an unfolding mechanism, and during the extrusion process, the angle between the two top plates can be changed, thereby supporting the top of the outdoor tent, so that the outdoor tent can be unfolded. By setting an arc tube, the second connecting frame can be connected to the first connecting frame and the arc rod can be limited. By setting a limiting rod, the rotating ring can be limited so that the rotating ring can rotate at the end of the limiting rod, thereby making the two top plates able to stably rotate with the limiting rod as the center, which is convenient for unfolding the outdoor tent.

[0018] 3. The outdoor tent support frame is provided with a trigger mechanism, which can squeeze the sliding block in the unfolding mechanism when the distance between the unfolding mechanism and the bottom plate changes, thereby causing the sliding block and the arc rod to slide, and finally allowing the two top plates to rotate with the limit rod as the center.

[0019] 4. The outdoor tent support frame can increase the support strength of the first connecting frame by setting two limit tubes to prevent the tent from shaking during the unfolding process.
