[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 and Figure 2 FIG. 1 is a schematic diagram of an embodiment of a quick connector for disassembling and assembling a transformer respirator provided by the present invention. In this embodiment, it includes:

[0026] Female flange 1, female quick connector 2, male quick connector 3, male flange 4, fastening screws 5; the male flange 4 is connected to the respirator flange 6 by a plurality of fastening screws 5, and the female flange 1 is fixedly connected to the equipment end flange 7; the other end of the female flange 1 is also connected to the female quick connector 2, and the other end of the male flange 4 is also connected to the male quick connector 3, and the male quick connector 3 and the female quick connector 2 are mutually engaged and fixed; the respirator flange 6 is arranged on the respirator body 8, and the equipment end flange 7 is arranged on the transformer. It can be understood that there is an equipment end flange 7 on the equipment end, and there is a respirator flange on the respirator body 8, which is mainly used to connect the equipment end flange 7 and the respirator flange 6, so as to realize the air path connection between the equipment end and the respirator. The male flange 4 is connected to the respirator flange 6 by fastening screws 5, and the female flange 1 is also connected to the equipment end flange 7 by screws. When the respirator is subsequently installed, the respirator can be quickly disassembled and assembled only through the quick disassembly and assembly structure of the quick connector female 2 and the quick connector male 3, thereby improving maintenance efficiency.

[0027] An embodiment, such as Figure 3 and Figure 5 As shown, the male quick connector 3 includes a tapered connector 9 arranged in the middle, a male connector block 10 is arranged outside the tapered connector 9, and the tapered connector 9 is connected to the respirator body 8 through the male flange 4. The male connector block 10 is integrally formed with the tapered connector 9, and an internal thread 11 is arranged on the inner wall of the male connector block 10. An outer hexagonal profile 17 is arranged on the outer wall of the male connector block 10 to facilitate the insertion of a wrench.
