Description

Technical Field

[0001] This utility model relates to the field of daily life, and in particular to a spring-connected mosquito net bracket with anti-slip sleeve. Background Technology

[0002] Chinese Patent ZL202421584593.6 discloses a mosquito net support frame, including a crossbar, a three-way tube on one side of the crossbar, a limiting mechanism on one side of the crossbar, and a positioning mechanism on one side of the three-way tube. This mosquito net support frame, by setting a fixing ring, allows for the fixing of side rods one and two. First, a fixing ring is fixedly connected to one end of side rod two. A lever and a positioning block are rotatably connected to one side of the fixing ring via a fixing plate. The positioning block allows for the compression and limiting of side rod one, thus fixing side rod one inside side rod two. When side rods one and two need to be stored, rotating the lever causes the positioning block to detach from one side of side rod one, allowing side rod one to slide inside side rod two. This device facilitates the fixing of side rods one and two.
