Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-5, the elastic sealing sleeve comprises a fixed block 1, wherein two sides of the fixed block 1 are both provided with a connecting pipe 2, the surface of the connecting pipe 2 is provided with a sleeve nut 5 through an external thread 3 and an internal thread 4, the interior of the sleeve nut 5 is fixedly connected with an extrusion block 6, the top and the bottom of one side of the two extrusion blocks 6 are both fixedly connected with a sleeve 18, the inner wall of the connecting pipe 2 is fixedly connected with a vertical plate 8, the bottom of one side of the vertical plate 8 is provided with an extrusion plate 9, two sides of the top of the extrusion plate 9 are both fixedly connected with first rotating blocks 13, the top of the two first rotating blocks 13 is provided with first connecting rods 12, one ends of the two first connecting rods 12 far away from the first rotating blocks 13 are both provided with second connecting rods 11, one ends of the two second connecting rods 11 far away from the first connecting rods 12 are both provided with second rotating blocks 10, and one sides of the two, and the top of two second turning blocks 10 all with the top fixed connection of connecting pipe 2 inner walls, utilize extrusion spring 14 self elastic force to paste extrusion plate 9 and cutting ferrule 18 tightly mutually, and make cutting ferrule 18 more paste tightly with water pipe 7, thereby the leakproofness of connecting pipe 2 and water pipe 7 has been guaranteed, again because the setting of extrusion spring 14, make novice also can not lead to cutting ferrule 18 or water pipe 7 to damage because of violently too hard when rotating several rings of cutting ferrule nuts 5 carelessly, make the installation convenient and fast more, and reduce the potential safety hazard.

Further, the top of stripper plate 9 and the equal fixedly connected with third turning block 15 in top of 2 inner walls of connecting pipe, all rotate between the relative one side of two third turning blocks 15 and connect back connecting rod 16, fixedly connected with spring telescopic link 17 between the relative one side of two connecting rods 16 further increases the elastic force between stripper plate 9 and cutting ferrule 18, guarantees the leakproofness.

Furthermore, both sides of the fixing block 1 are communicated with one end of the connecting pipe 2, and the bottom of one side of the vertical plate 8 is rotatably connected with one side of the extrusion plate 9.

Further, the inner wall threaded connection of external screw thread 3 and internal thread 4 and cutting ferrule nut 5 is passed through on the surface of connecting pipe 2, and external screw thread 3 sets up in the surface of connecting pipe 2, and internal thread 4 sets up in the inner wall of cutting ferrule nut 5.

Further, the tops of the two first rotating blocks 13 are rotatably connected with one end of the first connecting rod 12, one ends of the two first connecting rods 12, which are far away from the first rotating blocks 13, are rotatably connected with one ends of the second connecting rods 11, and one ends of the two second connecting rods 11, which are far away from the first connecting rods 12, are rotatably connected with the bottoms of the second rotating blocks 10.

Further, the opposite sides of the extrusion plate 9 and the clamping sleeve 18 are fixedly connected with a sealing ring 19, and the opposite sides of the two extrusion blocks 6 are movably connected with a water pipe 7, so that the sealing performance between the water pipe 7 and the connecting pipe 2 is further improved due to the arrangement of the sealing ring 19.

The working principle is as follows: the elastic sealing cutting sleeve, through the arrangement of the first rotating block 13 and the first connecting rod 12, when the cutting sleeve nut 5 rotates to drive the cutting sleeve 18 to move, the cutting sleeve 18 extrudes the extrusion plate 9 to drive the first rotating block 13 to move, the first rotating block 13 drives the first connecting rod 12 and the second connecting rod 11 to move, and simultaneously drives the extrusion spring 14 to generate deformation, so that the pressing plate 9 and the ferrule 18 are tightly attached to each other by the elastic force of the pressing spring 14 itself, and the ferrule 18 is more tightly attached to the water pipe 7, thereby ensuring the tightness of the connecting pipe 2 and the water pipe 7, and because of the arrangement of the pressing spring 14, so that the clamping sleeve 18 or the water pipe 7 can not be damaged by over-force when a novice rotates a plurality of rings of clamping sleeve nuts 5 carelessly, the installation is more convenient and faster, and the potential safety hazard is reduced, and the sealing performance between the water pipe 7 and the connecting pipe 2 is further increased due to the arrangement of the sealing ring 19.
