Detailed Description

The technical solution in the practice of the present invention will be clearly and completely described below with reference to the accompanying drawings in the practice of the present invention. As shown in fig. 1 to fig. 6, the following technical solutions are adopted in the present embodiment:

a ventilation pipeline convenient to install comprises a first ventilation pipeline 1, a second ventilation pipeline 2, a first fixing ring 3, a second fixing ring 4 and a convex ring 6.

The outer side surface of the first ventilating duct 1 is provided with a first fixing ring 3 in a sliding mode, and the outer side surface of the second ventilating duct 2 is provided with a second fixing ring 4 in a sliding mode.

Annular 5 has been seted up to air pipe 1 one end face, and air pipe two 2 is being provided with bulge loop 6 in the one end of being close to air pipe 1 is fixed, and bulge loop 6 is coaxial with annular 5, and bulge loop 6 and annular 5 phase-match keep rotating in 5 of inlay of annular in the time of the installation and connect, and the direction of rotation of bulge loop 6 is for the axle center circumferential direction around air pipe 1.

One end of the first ventilation pipeline 1, which is provided with the annular groove 5, is fixedly connected with a sealing ring 13. When the convex ring 6 is matched with the ring groove 5, the sealing ring 13 is extruded by the first ventilating pipeline 1 and the second ventilating pipeline 2, and a better sealing effect is provided.

The outer edge of the convex ring 6 is chamfered. The convex ring 6 is matched with the ring groove 5 conveniently.

The outer surface of the convex ring 6 is provided with a groove 7, the bottom of the groove 7 is fixedly connected with a spring 8, and the other end of the spring 8 is fixed at the bottom of the elastic block 9. The elastic block 9 is pressed downwards, and the elastic block 9 compresses the spring 8 to enable the top end of the elastic block 9 to be lower than the surface of the convex ring 6.

The two sides of the ring groove 5 are provided with sliding grooves 10 outwards, sliding blocks 11 which move up and down are arranged in the sliding grooves 10 in a sliding mode, two side walls of each sliding groove 10 are provided with long grooves 14, and two sides of the bottom end of each sliding block 11 are fixedly connected with limiting blocks 15.

The limiting blocks 15 are all arranged in the corresponding long grooves 14 in a sliding mode, and through holes 12 penetrating through the end faces of the two sides are transversely formed in the sliding blocks 11.

When the groove 7 of the convex ring 6 and the sliding groove 10 of the annular groove 5 move to corresponding positions, the spring 8 in the groove 7 recovers when the pressure is reduced, the top end of the elastic block 9 is in contact with the bottom end of the sliding block 11 and jacks up the sliding block 11, and the through hole 12 in the sliding block 11 is exposed out of the outer surface of the ventilation pipeline 1. When the sliding block 11 exposed out of the first ventilation pipeline 1 is seen, whether the connection of the first ventilation pipeline 1 and the second ventilation pipeline 2 is completed or not can be judged, and the subsequent installation is facilitated.

The position of the first fixing ring 3, corresponding to the through hole 12 exposed out of the sliding block 11, is fixedly connected with an inserting rod 16, and the position of the second fixing ring 4, corresponding to the inserting rod 16, is provided with an inserting hole 17. When the first fixing ring 3 is tightly attached to the second fixing ring 4, the connecting part of the ventilating pipeline can be protected, and the connecting part of the ventilating pipeline is prevented from being in a severe environment, so that the service life is shortened.

The outer surfaces of the first fixing ring 3 and the second fixing ring 4 are fixedly connected with connecting lugs 18, and the connecting lugs 18 are fixed through fastening bolts 19. The ventilation pipeline I1 and the ventilation pipeline II 2 are connected more firmly through the fixing bolts.

The working principle of the specific implementation mode is as follows: aligning a convex ring 6 of a first ventilation pipeline 2 with a ring groove 5 of the first ventilation pipeline 1, compressing an elastic block 9 in a groove 7 on the surface of the convex ring 6 into the groove 7, abutting the convex ring 6 against the ring groove 5 to enable a sealing ring 13 to be in contact with the first ventilation pipeline 1, rotating the second ventilation pipeline 2 to enable the elastic block 9 to rotate to the position of a sliding block 11, ejecting the elastic block 9 and the sliding block 11 by a spring 8 at the moment, exposing a through hole 12 in the sliding block 11 out of the surface of the first ventilation pipeline 1, respectively attaching a first fixing ring 3 and a second fixing ring 4 along the surface of the pipeline at the moment, aligning an inserted rod 16 on the first fixing ring 3 with the through hole 12 in the sliding block 11, aligning connecting lugs 18 on the fixing rings after the inserted rod 16 passes through the through hole 12 and is tightly attached to a jack 17 on the second fixing ring 4, placing a fixing bolt 19 to be screwed tightly to fix the fixing rings at the moment, loosening the fixing bolt 19 when disassembly is needed, separating the first fixing ring 3 from the second fixing ring 4, keeping the inserted rod 16 away from the sliding block 11 with the through hole 12, pressing down the sliding block 11 and compressing the spring 8 to enable the ventilation pipeline 7 to rotate to separate the second ventilation pipeline 2.
