Preferably, the buckles without springs are arranged on the upper flange at equal intervals, and the I-shaped buckle with the springs is arranged between two buckles without springs.

Preferably, a welding clearance groove is formed at the joint of the upper part of the upper flange and the outer pipe, and a welding clearance groove is formed at the joint of the lower part of the lower flange and the inner pipe.

Compared with the prior art, the utility model has the following advantages of solving the problems that the hanging fireplace pipeline needs to be assembled and disassembled by using special tools and being assisted by multiple persons in the process of assembling and disassembling. The product is more perfect in appearance. During assembly, a first pipeline is fixed to a roof surface, then when a second pipeline is installed, an upper flange of the second pipeline is aligned with a lower flange of the first pipeline, particularly, a buckle is required to be aligned with a clamping groove, an I-shaped buckle with a spring is jacked into a buckle notch by hands or a straight rod, other buckles are also aligned and jacked into the buckle notch, then the second pipeline is integrally rotated, so that the buckle can enter a positioning notch along an arc-shaped precession groove, all buckles can be lapped on the positioning notch, the I-shaped spring with the spring buckle can abut against the bottom of the upper flange, and the arrangement can prevent the second pipeline from rotating, and ensure the connection stability of the first pipeline and the second pipeline.
