[0001] This utility model relates to the field of household protective devices, and in particular to a foldable rod connection assembly and a foldable mosquito net support frame. Background Technology

[0002] Currently, the frame-type mosquito net support structure on the market typically uses multiple poles assembled together via T-joints or multi-joint connectors to form a support frame for hanging the mosquito net body. The poles in this type of mosquito net support frame are mostly connected by threads. Assembly requires matching numerous poles of varying lengths, aligning them, and then twisting them together before inserting each pole into multiple connectors. This connection method is cumbersome during installation and disassembly, and can easily lead to assembly difficulties or damage to the connectors.

[0003] Furthermore, existing foldable frame mosquito nets have complex connection structures between the poles, and these connections are unstable. They tend to wobble significantly under external forces, and after prolonged use, they are prone to loosening, leading to a decrease in the overall stability of the frame and affecting the effectiveness and safety of the mosquito net.

[0004] In response to the above situation, there is an urgent need in the market for a rod connection component that can achieve rapid assembly and disassembly, ensure stable connection, and facilitate storage, so as to solve the problems of cumbersome installation and disassembly, inconvenient storage, and insufficient connection stability in the existing technology.
