TECHNICAL FIELD

[0001] The utility model belongs to the field of daily necessities, specifically relates to a connecting piece that can be quickly unfolded, a mosquito net rod assembly and a mosquito net. BACKGROUND

[0002] In daily necessities, mosquito nets have been widely used since ancient times as a traditional and effective tool for preventing mosquitoes. It not only provides a safe and comfortable sleeping environment for people, but also is particularly suitable for protecting people from mosquito bites during hot seasons or outdoor activities. However, the traditional mosquito net design has many inconveniences: they usually need to be manually unfolded and stored, which often takes a lot of time and is not convenient for users, especially in limited spaces such as dormitories and camping sites. The traditional support structure cannot meet the needs of modern people for quick setup and efficient storage, which is particularly inappropriate in today's fast-paced life. SUMMARY

[0003] In addition, most mosquito net supports on the market currently use fixed frame structures or simple folding designs. These designs, while solving the support problem of mosquito nets to some extent, have exposed a series of problems in actual use. For example, the unfolding and storage process is relatively cumbersome, and users need to spend extra time to complete these steps; moreover, due to design limitations, these mosquito nets are not easy to maintain their shape after being stored, and may need to be adjusted again when used, seriously affecting the user experience. Especially for modern consumers who pursue efficiency and convenience, such designs obviously cannot fully meet their needs.

[0004] Chinese patent CN105332977B discloses a connecting piece of a folding support, belonging to the field of connecting pieces of folding supports, designed to solve the problems of existing connecting pieces, such as complicated disassembly and assembly, poor load-bearing capacity, etc. The connecting piece of the folding support includes a hinge part and a locking piece; the hinge part is arranged between the first rod body and the second rod body to be connected, and the second rod body can rotate around the hinge part; when the second rod body is in an unfolded state, the locking piece can clamp the second rod body relative to the first rod body. The connecting piece of the folding support has simple disassembly and assembly procedures, is convenient to use, saves time and effort, and has good clamping effect. The above device realizes the rotation of the connecting piece through the hinge part and the locking piece, and the pressure is concentrated in the hinge part during use, so only one hinge part is set, which is worn out and causes the overall device to have a short service life. Therefore, it is urgent for technical personnel in the field to solve the above technical problems. SUMMARY
