[ detailed description ] embodiments

For the purpose of enhancing the understanding of the present invention, the present invention will be further described in detail with reference to the following examples and the accompanying drawings, which are only used for explaining the present invention and are not to be construed as limiting the scope of the present invention.

Referring to fig. 1-3, the present invention provides an improved joint, which comprises a joint body 1 and a fastening ring 2, wherein the joint body 1 has an inlet end and an outlet end, the inlet end is used for connecting an exhaust pipe, the outlet end is used for connecting a window baffle, the inlet end of the joint body 1 has an inner annular wall 3 and an outer annular wall 4 arranged around the inner annular wall 3, a pipeline insertion cavity 5 is formed between the inner annular wall 3 and the outer annular wall 4, the fastening ring 2 is sleeved on the outer ring wall 4, the fastening ring 2 can tighten the outer ring wall 4 to enable the outer ring wall 4 to deform inwards and tighten so as to enable the pipeline plugging cavity 5 to be reduced, when the exhaust pipe is installed, the exhaust pipe is firstly sleeved on the inner ring wall 3, namely, the exhaust pipe is embedded into the pipe inserting cavity 5, and then the outer annular wall 4 is tightly extruded through the fastening ring 2, so that the outer annular wall 4 is inwardly deformed and tightened, therefore, the pipeline insertion cavity 5 is reduced, and the exhaust pipeline is clamped by the extrusion of the outer ring wall 4 and the inner ring wall 4.

Be equipped with external screw thread structure 6 on the lateral wall of outer rampart 4, be equipped with on the inside wall of tighrening ring 2 with external screw thread structure 6 complex internal thread structure 7, external screw thread structure and internal thread structure's cooperation can convenience of customers adjustment tighrening ring 2 to more easy to assemble or dismantle the exhaust pipe.

In order to make the deformation of the outer annular wall 4 easier to control, a plurality of notches 8 are circumferentially distributed on the wall body of the outer annular wall 4, and the notches 8 divide the wall body of the outer annular wall 4 into a plurality of wall blocks, so that when the fastening ring 2 is adjusted, the plurality of independent wall blocks are easier to deform and clamp the exhaust duct.

A plurality of convex parts 9 are circumferentially distributed on the outer side wall of the fastening ring 2, the convex parts 9 form an anti-slip structure, friction force can be enhanced by the anti-slip structure, and the phenomenon of slipping of a user when the fastening ring 2 is rotated is prevented.

Connect the end that connects the end of body 1 and be equipped with the elasticity back-off 10 of at least three circumference equipartition, elasticity back-off 10 can be for connecing the end inside to warp, open on the window baffle have with connect the hole site that the end is connected, when the erection joint body, will connect the hole site that the end stretches into the window baffle to extrude elasticity back-off 10 when stretching into, thereby after elasticity back-off 10 passes through the hole site, resume to warp and detain this hole site, make and connect body 1 installation to fix on the window baffle.

Because the exhaust pipe on the market is mostly the bellows, and the inside wall of interior rampart 3 is equipped with bulge loop (not shown in the figure), and the bellows imbeds behind the pipeline grafting chamber, when fixed through the tighrening ring fastening, on the bulge loop of interior rampart 3 can imbed the recess on the bellows, played limiting displacement, can further prevent that the bellows pine from taking off.

In the present embodiment, the wall thickness of the outer annular wall 4 is 0.5-1.5mm, the wall thickness of the inner annular wall 3 is 2-5mm, the thickness of the outer annular wall 4 is preferably 1mm, and the thickness of the inner annular wall 3 is preferably 2mm, and the outer annular wall has better deformability under the design of the thickness, and the inner annular wall 3 also has certain structural stability and is not easy to deform.

The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited to the above embodiment, but equivalent modifications or changes made by those skilled in the art according to the present disclosure should be included in the scope of the present invention as set forth in the appended claims.
