[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 2 As shown, the utility model provides a pipeline sealing device for a sterile workshop, comprising a plurality of pipelines 1, connecting components 2 being provided on opposite sides of adjacent pipelines 1, and two mounting components 3 being provided on the left and right sides of the outer surface of the connecting component 2 in a mirror-like manner;

[0025] The internal arrangement of the connecting component 2 facilitates sealing of two adjacent pipes 1 , and at the same time, the two adjacent pipes 1 are installed and fixed through the installation component 3 .

[0026] like Figure 3 As shown, the connection component 2 includes a connecting column 21, a through hole 22 is opened in the middle of the connecting column 21, and sockets 23 are opened on the left and right sides of the through hole 22. The side of the socket 23 away from the through hole 22 is communicated with the inside and outside. The diameter of the through hole 22 is smaller than the diameter of the socket 23. A sealing rubber ring 24 is fixedly connected to the middle of the inner wall of the left and right sockets 23. The left and right ends of the plurality of pipes 1 are fixedly connected with a sleeve 11. The side of the sleeve 11 away from the pipe 1 is fixedly connected with a plug connector 12. The plug connector 12 and the sealing rubber ring 24 have two mirror-imaged conical surfaces 13 on the left and right sides. The length of the plug connector 12 is greater than the length of the sealing rubber ring 24. The outer surfaces of the sleeve 11 and the plug connector 12 are plugged into the interior of the socket 23. The outer surface of the sleeve 11 overlaps and presses against the inner side of the sealing rubber ring 24. The sealing rubber ring 24 is in a contracted state. The material of the sealing rubber ring 24 is EPDM rubber.

[0027] During use, the sleeve 11 and the plug connector 12 in the pipe 1 are inserted into the socket 23, so that the tapered surface 13 in the plug connector 12 contacts and squeezes the sealing rubber ring 24. When inserted into the appropriate position, the outer surface of the sleeve 11 fits tightly with the inner side of the sealing rubber ring 24 to achieve a sealing effect. The angle of the tapered surface 13 in the plug connector 12 is smaller than the angle of the tapered surface 13 in the sealing rubber ring 24. The arrangement of the tapered surfaces 13 in the plug connector 12 and the sealing rubber ring 24 facilitates quick removal and disassembly.

[0028] like Figure 4 As shown, the two mounting components 3 both include a positioning rubber sleeve 31, the inner side of the positioning rubber sleeve 31 is fixedly connected to the outer surface of the pipe 1, the outer surface of the positioning rubber sleeve 31 is provided with a sleeve 32, the inner wall left side of the sleeve 32 is communicated with the inside and outside, the inner side of the sleeve 32 overlaps the outer surface of the connecting column 21, and the outer surface of the sleeve 32 is provided with an L-shaped groove 33 at the top and bottom. The left side of the inner wall of the left and right horizontal directions of the L-shaped groove 33 is communicated with the inside and outside, and a positioning groove 34 is provided on the front and back horizontal left sides of the L-shaped groove 33. The upper and lower L-shaped grooves 33 and the positioning grooves 34 are mirror-set, and the interiors of the upper and lower positioning grooves 34 are clamped with L-shaped blocks 37. The horizontal left side of the L-shaped block 37 is fixedly connected to a mounting ring 36, the inner side of the mounting ring 36 is movably connected to the outer surface of the connecting column 21, and the right side of the mounting ring 36 is overlapped with an elastic rubber ring, and the inner right side of the elastic rubber ring 35 is fixedly connected to the outer surface of the connecting column 21.

[0029] After sealing, by rotating the sleeve 32 and the mounting ring 36, the L-shaped groove 33 is aligned with the L-shaped block 37 in the horizontal direction, and by pushing the sleeve 32 and the mounting ring 36 on both sides, the sleeve 32 moves and drives the positioning rubber sleeve to stretch, and the mounting ring 36 pushes and squeezes the elastic rubber ring 35, so that the L-shaped block 37 enters the interior of the L-shaped groove 33 and rotates the mounting ring 36 to drive the L-shaped block 37, and then by loosening the sleeve 32 and the mounting ring 36, the stretched positioning rubber sleeve 31 is brought The movable sleeve 32 moves to the right, and the contracted elastic rubber ring 35 pushes the mounting ring 36 to move to the left, so that the vertical outer surface of the L-shaped block 37 is clamped with the inner wall of the positioning groove 34, thereby achieving a quick installation effect. Conversely, by moving the sleeve 32 and the mounting ring 36 and stretching the positioning rubber sleeve 31, and the elastic rubber ring 35 contracts, the L-shaped block 37 is separated from the inside of the positioning groove 34 and enters the inside of the L-shaped groove 33 and the mounting ring 36 is rotated, so that the L-shaped block 37 is separated from the L-shaped groove 33, and the operation is completed.

[0030] like Figure 5 As shown, an annular groove 311 is formed in the middle of the outer surface of the positioning rubber sleeve 31, and a circular opening is formed on the right side of the sleeve 32, which is connected to the left and right sides. The inner side of the circular opening and the right outer surface of the sleeve 32 are movably connected to the inside of the annular groove 311. A sealing gasket 321 is fixedly connected to the left side of the inner wall of the sleeve 32. The left side of the sealing gasket 321 overlaps and presses against one side of the connecting column 21.

[0031] During installation, the sealing gasket 321 is tightly fitted to one side of the connecting column 21 , which facilitates the extrusion of the sealing gasket 321 and enhances the sealing performance after installation. The annular groove 311 and the circular opening are provided to facilitate the rotation of the sleeve 32 .

[0032] The following is a detailed description of the working principle of the pipeline sealing device in the sterile workshop.

[0033] When in use, the sleeve 11 and the plug connector 12 in the pipeline 1 are inserted into the socket 23, so that the tapered surface 13 in the plug connector 12 contacts and squeezes and shrinks the sealing rubber ring 24. When inserted into the appropriate position, the outer surface of the sleeve 11 is tightly fitted with the inner side of the sealing rubber ring 24 to achieve a sealing effect. After sealing, the sleeve 32 and the mounting ring 36 are rotated to align the L-shaped groove 33 with the L-shaped block 37 in the horizontal direction, and the sleeve 32 and the mounting ring 36 on both sides are pushed to move, so that the L-shaped block 37 enters the interior of the L-shaped groove 33 and the mounting ring 36 is rotated to drive the L-shaped block 37. Then, by loosening the sleeve 32 and the mounting ring 36, the vertical outer surface of the L-shaped block 37 is clamped with the inner wall of the positioning groove 34 under the action of the stretched positioning rubber sleeve 31 and the contracted elastic rubber ring 35, thereby achieving a quick installation effect.

[0034] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
