DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example: See Figure 1-5 The utility model discloses a highly sealed connectable double-walled corrugated pipe, comprising a first connecting pipe 1 and a second connecting pipe 3. A sealing locking mechanism 2 is provided at the connection between the first connecting pipe 1 and the second connecting pipe 3. The sealing locking mechanism 2 is composed of a first connecting sleeve 4 and a second connecting sleeve 6. A first stop block 5 is provided inside the first connecting pipe 1, and a second stop block 7 is provided inside the second connecting pipe 3. By setting the sealing locking mechanism 2, the double-walled corrugated pipe can be better connected and the sealing of the double-walled corrugated pipe connection can be ensured; both the first connecting sleeve 4 and the second connecting sleeve 6 are provided with abutting grooves 12, the first connecting pipe 1 abuts in the abutting groove 12 of the first connecting sleeve 4, the second connecting pipe 3 abuts in the abutting groove 12 of the second connecting sleeve 6, the first connecting sleeve 4 Abutment pads 8 are provided on the side ends of the abutment grooves 12 with the second connecting sleeve 6. By arranging the abutment pads 8 between the connecting pipe and the abutment block, the abutment block can be better pressed against the connecting pipe, thereby ensuring the air tightness of the connection between the first connecting sleeve 4 and the second connecting sleeve 6; the first connecting sleeve 4 and the second connecting sleeve 6 are both sleeved with tie rings 9, and a threaded clamping mechanism 11 is provided at the connection of the tie rings 9. The threaded clamping mechanism 11 is composed of two pads and two connecting bolts. The pads are fixedly connected to the two ends of the tie ring 9, and two connecting bolts are symmetrically penetrated on the pads. Through the arrangement of the tie ring 9 and the threaded clamping mechanism 11, the air tightness of the connection between the abutment block, the connecting pipe and the connecting sleeve can be further enhanced by clamping, and the position of the connecting sleeve on the connecting pipe can be fixed.

[0021] In the present invention, the first connecting sleeve 4 and the second connecting sleeve 6 are both provided with connecting holes 10 for passing fixing bolts, and sealing gaskets are provided on the abutting mounting surfaces of the first connecting sleeve 4 and the second connecting sleeve 6.

The setting of the abutment ring groove 13 on the block 7 can increase the friction between the abutment block and the connecting pipe, thereby enhancing the anti-separation ability of the connection between the first connecting pipe 1 and the second connecting pipe 3; the side surfaces of the first abutment block 5 and the second abutment block 7 abut against each other, and the side surfaces of the first abutment block 5 and the second abutment block 7 are equidistantly provided with a number of sealing convex rings 14 for abutting and squeezing each other. Through the setting of the sealing convex rings 14 on the abutment blocks, the sealing convex rings 14 can abut against each other when the first connecting pipe 1 and the second connecting pipe 3 are connected to form an abutting rubber seal, thereby providing auxiliary sealing for the connection of the device.

[0022] Working principle: When the utility model is used, the first connecting sleeve 4 is first sleeved on the first connecting pipe 1, and then the abutment pad 8 at the bottom of the first connecting sleeve 4 is extended into the first connecting pipe 1, and at the same time, the first abutment block 5 is pressed and inserted into the first connecting pipe 1 together, and then the outer layer of the first connecting sleeve 4 is sleeved with the tie ring 9, and then the tightness of the tie ring 9 fixing the first abutment block 5, the first connecting pipe 1 and the first connecting sleeve 4 is controlled by adjusting the connecting bolts on the threaded clamping mechanism 11, and then the second connecting sleeve 6 and the second abutment block 7 are fixed on the second connecting pipe 3 according to the above operation, and then the first connecting pipe 1 and the second connecting pipe 3 are fixed by abutting the fixing bolts inserted into the connecting hole 10, and the fixing bolts and sealing gaskets inserted in the connecting hole 10 can better prevent the connection from loosening, thereby improving the air tightness of the connection between the first connecting sleeve 4 and the second connecting sleeve 6, and the sealed connection of the double-wall corrugated pipe is completed.
