Detailed Description

The following provides a detailed description of a docking assembly for a heating and ventilation duct according to the present invention with reference to the accompanying drawings.

In order to solve the technical problem of air leakage at the joint of the pipelines, a butt joint component for a heating ventilation pipeline is provided as shown in fig. 1, 2 and 3, and is characterized in that: including interior body 1 and outer body 2, through fixed block 3 fixed connection between the department in the middle of interior body 1 and the outer body 2, all be connected through a plurality of centre gripping subassemblies 4 between interior body 1 both ends and the outer body 2, centre gripping subassembly 4 is including setting up the swing arm 4.1 in the outer body 2 outside, swing arm 4.1 one side fixedly connected with runs through the threaded rod 4.2 through the 2 lateral walls of outer body, threaded rod 4.2 is kept away from 4.1 one end rotations of swing arm and is connected with grip block 4.3.

As shown in fig. 1, 2 and 3, in the present invention, the outer tube 2 is sleeved outside the inner tube 1.

As shown in fig. 1 and fig. 3, the outer surfaces of the two ends of the inner tube body 1 are provided with seal rings 5.

As shown in fig. 3, in the present invention, a rubber cushion 4.4 is disposed on a side surface of the clamping block 4.3 close to the inner tube 1.

As shown in fig. 1 and fig. 3, the utility model discloses in be equipped with the screw hole that supplies threaded rod 4.2 to pass through on the 2 lateral walls of outer body, threaded rod 4.2 surface is equipped with the external screw thread, it is equipped with the internal thread that meshes mutually with the external screw thread to lie in screw hole department on the 2 lateral walls of outer body.

As shown in fig. 1 and fig. 3, in the utility model, one end of the threaded rod 4.2 is rotatably connected with the clamping block 4.3 through the bearing 4.5, the clamping block 4.3 is provided with a bearing groove for installing the bearing 4.5.

As shown in fig. 3, the plurality of clamping blocks 4.3 located on the same side form a circular ring shape, and the clamping blocks 4.3 are adapted to the inner pipe body 1.

The working principle is as follows: the utility model discloses when concrete implementation, at first this it is installed between two heating air pipe, when installing heating air pipe, with heating air pipe pot head between interior body 1 and outer body 2, heating air pipe pot head is in the outside of interior body 1 one end this moment, it rotates 4.1 drive threaded rod 4.2 to rotate the swing arm 4.2, because the external screw thread on threaded rod 4.2 surface meshes with the internal thread of screw hole department mutually, consequently can move to 1 one side of interior body when threaded rod 4.2 pivoted, because threaded rod 4.2 rotates through bearing 4.5 with grip block 4.3 and is connected, consequently, grip block 4.3 moves to 1 one side of interior body, and carry out the centre gripping to the heating air pipe of pot head in the interior body 1 outside and fix, simultaneously sealing washer 5 can make interior body 1 inseparabler with heating air pipe be connected, rubber cushion 4.4 can play the guard action to heating air pipe and interior body 1, prevent that heating air pipe and interior body 1 between fixed inseparable, prevent simultaneously that heating air pipe and interior body 1 from receiving the extrusion and taking place the damage, the phenomenon of having avoided gas leakage takes place.
