Detailed Description

In order to make the technical solution of the present invention better understood, the technical solution of the embodiments of the present invention will be clearly and completely described below, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.

As shown in figures 1 to 4.

The utility model provides a connecting device for the installation of a ventilation pipe small space, which comprises a splint 1 and is characterized in that the splint 1 is welded around the central part of the outer surface of a connecting plate 2, connecting parts of the upper and lower ends of the inner side of the splint 1 and the connecting plate 2 are respectively provided with a connecting groove 3 for connecting a ventilation pipe, and the connecting groove 3 is clamped with a ventilation pipe 4; the connecting plate 2 is divided into a wide plate 21 and a narrow plate 22, the wide plate 21 and the narrow plate 22 are connected in a spaced welding mode, and clamping tongues 23 clamped with clamping grooves in the ventilation pipe 4 are arranged on the upper side and the lower side of the outer sides of the wide plate 21 and the narrow plate 22.
