Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood by concrete condition
Concrete meaning in the present invention.
The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
A kind of novel pipeline extension apparatus, as shown in Figure 1, including casing 1 and telescoping tube 2, middle sleeve 1 is consolidated with mud tube
Fixed part connects, casing 1 and the mud tube flanged joint added.2 one end of telescoping tube is set in casing 1, and telescoping tube 2 and set
The sliding connection of pipe 1.2 plug-in-sleeve of telescoping tube, 1 one end is circumferentially equipped with three row's guide slip shoes 3, in order to slide.
Casing 1 is inserted into one end for telescoping tube 2 and is provided with sealing device 4, and sealing device 4 includes seal pipe 41, airtight and watertight padding
42 and hold down assembly 5.Seal pipe 41 is set in outside telescoping tube 2, and with 1 flanged joint of casing.Seal pipe 41 with 1 flange of casing
One end is connected, extends inwardly at telescoping tube 2 and is formed with abutting platform 411；Airtight and watertight padding 42 in a ring, is sheathed with telescoping tube one by one
Between 2 and seal pipe 41, and it is connected to and abuts on platform 411.
Hold down assembly 5 include clamping sleeve 51, bolt 52 and elastic component 53.Clamping sleeve 51 includes tube body 511 and from tube body
The connecting portion 512 that 511 one end are radially expanded.511 end of tube body is inserted between seal pipe 41 and telescoping tube 2, and will be close
Packing material 42, which is pressed in, to abut on platform 411.For seal pipe 41 close to 512 one end of connecting portion, radially expansion is formed with connection
