Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description will be given with reference to the accompanying drawings and preferred embodiments in order to provide the best mode, structure, features and effects according to the present invention.

Please refer to fig. 2, fig. 3, fig. 4, the first embodiment of the present invention provides a first embodiment of a second embodiment of a third embodiment of a second embodiment of a third embodiment of a second embodiment of a third embodiment of a second embodiment of a third embodiments of a second embodiment of a third embodiments of a second embodiments of a third embodiments of a second embodiments of a third embodiments of a fourth embodiments of a third embodiments of. The area of contact of sealing washer 2 and connecting plate 31 is because of the increase of stagnant water groove 311 to promote sealed effect, sealing washer 2 increases with connecting plate 31 frictional force simultaneously, thereby prevents the displacement of sealing washer 2.

The sealing rings 2 are a pair, and the pair of sealing rings 2 are respectively fixed with the end parts of the composite pipe 1. The sealing ring 2 is provided with an axially extending limiting ring 21, and the limiting ring 21 is positioned between the fixing plate 32 and the composite pipe 1. The thickness of the sealing ring 2 is larger than that of the composite pipe 1, and the sealing ring 2 is respectively contacted with the composite pipe 1 and the connecting plate 31. The packing 2 is in contact with the end surface of the composite pipe 1, thereby preventing water inside the composite pipe 1 from contacting the end surface of the composite pipe 1.

The water stopping groove 311 is an annular groove, and the water stopping groove 311 protrudes from the surface of the connecting plate 31. During connection, the water stopping groove 311 protruding from the surface of the connecting plate 31 can be ensured to contact with the sealing ring 2 first, so that the sealing effect is ensured.

A plurality of the slips 3 are connected and fixed through bolts 4. The fixing plate 32 is provided with a first mounting hole 33, the fixing plate 32 is fixedly connected with another fixing plate 32 through the first mounting hole 33, the connecting plate 31 is provided with a second mounting hole 34, and the connecting plate 31 is fixedly connected with another connecting plate 31 through the second mounting hole 34.

The slips 3 are semicircular, and the fixing plate 32 is provided with a plurality of fixing teeth 321 corresponding to the outer wall of the composite pipe 1. When fixing, the fixing teeth 321 make the outer wall of the composite pipe 1, thereby improving the fixing effect.
