in the upper diagram: the device comprises a sticking and blocking pipe main body 1, an upper transverse isolation rubber ring 2, a middle transverse isolation rubber ring 3, a lower transverse isolation rubber ring 4, a longitudinal isolation rubber strip 5, an upper joint 6, a connecting hole 7, a fixed inner pipe 8, a steel nail supporting seat 9 and an ejector 10.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Example 1, referring to fig. 1, the utility model provides a bushing leakage repairing type plugging pipe, which comprises a plugging pipe main body 1, an upper transverse isolation rubber ring 2, a middle transverse isolation rubber ring 3, a lower transverse isolation rubber ring 4, a longitudinal isolation rubber strip 5, an upper joint 6, a connecting hole 7 and a steel nail launching device, the sticking pipe main body 1 is of a cylindrical structure, a steel nail launching device is arranged in the inner cavity of the sticking pipe main body 1, the outer wall of the sticking pipe main body 1 is sequentially provided with an upper transverse isolation rubber ring 2, a middle transverse isolation rubber ring 3 and a lower transverse isolation rubber ring 4 at intervals, the inner cavities of the upper transverse isolation rubber ring 2, the middle transverse isolation rubber ring 3 and the lower transverse isolation rubber ring 4 are respectively provided with a longitudinal isolation rubber strip 5 which isolates a plurality of grid-shaped grooves, a plurality of groups of connecting holes 7 are arranged in the latticed groove, and steel nails in the steel nail launching device extend out of the connecting holes 7 to be anchored with the inner wall of the sleeve.
Referring to fig. 2, the steel nail launching device comprises a fixed inner tube 8, a steel nail supporting seat 9 and an ejector 10, a plurality of groups of steel nail supporting seats 9 are installed in a gap between the fixed inner tube 8 and the sticking and blocking tube main body 1, a steel nail is installed in an inner cavity of each steel nail supporting seat 9, and the ejector 10 triggered by the steel ball is arranged on the rear side of the steel nail.
The upper transverse isolation rubber ring 2, the middle transverse isolation rubber ring 3 and the lower transverse isolation rubber ring 4 are fixed on the outer wall of the sticking and plugging pipe main body 1.
The longitudinal isolation rubber strips 5 are provided with a plurality of groups and are respectively arranged between the upper transverse isolation rubber ring 2 and the middle transverse isolation rubber ring 3 and between the middle transverse isolation rubber ring 3 and the lower transverse isolation rubber ring 4.
The upper transverse isolation rubber ring 2, the middle transverse isolation rubber ring 3, the lower transverse isolation rubber ring 4 and the longitudinal isolation rubber strip 5 are respectively made of water-swelling rubber, and swell after meeting water, so that the sealing is better, and the leakage is avoided.
The steel nail launching device is triggered through the steel ball, the outer diameter of the steel ball is slightly smaller than the inner diameter of the fixed inner tube 8, and the ejector of the steel nail launching device arranged at the position of the fixed inner tube 8 can be hit after the steel ball is thrown down.
