Detailed Description

Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

As shown in fig. 1 to 5, it is a schematic structural diagram of the double-wall corrugation with the telescopic pipe provided by the present invention. The double-wall corrugation with telescopic pipe comprises a corrugated pipe body 10 and a telescopic pipe 20 arranged at the end of the corrugated pipe body 10, and the double-wall corrugation with telescopic pipe also comprises other functional modules, such as sealing rings, fastening screws and the like, which should be known by the skilled person, and will not be described in detail herein.

The bellows body 10 is used to transport fluid and as a carrier for mounting various components. The bellows main body 10 includes a pair of first connection portions 11 provided at both end portions of the bellows main body 10. The first connection portion 11 includes a first flange 111. A plurality of first mounting holes 112 are formed in the end surface of the first flange 111 at intervals. The first flange 111 and the first mounting hole 112 are used to connect with the telescopic tube 20, which will be described in detail below with reference to the telescopic tube 20.

The telescoping tube 20 includes an elbow 21 and a pair of telescoping tube interfaces 22 disposed at opposite ends of the elbow 21. The bellows adapter 22 is connected to the bellows body 10.

The elbow 21 includes a plurality of corrugated rings 211, and the corrugated rings 211 have certain ductility and flexibility. The crimp ring 211 may be made of polyethylene or rubber with high softness. Specifically, the bend 21 can be bent in any direction with itself as an axis, the bending range is 0 ° to 90 °, and the corrugated ring 211 can extend along the axial direction thereof. Specifically, when the bend 21 is bent, the side wall of the corrugated ring 211 forms two R angles with different radii. And the corrugated rings 211 on the side of the smaller radius R-angle are closed while the corrugated rings 211 on the side of the larger radius R-angle are stretched to accommodate the angle of the bend.

The expansion pipe joint 22 is used for connecting with the corrugated pipe main body 10. And a sealing ring 221 is arranged on the outer side wall of the connection part of the extension tube interface 22 and the end part of the corrugated tube main body 10. The sealing ring 221 may be made of high resilience rubber, so that the connection between the expansion pipe connector 22 and the bellows main body 10 is tighter, a gap at the connection between the expansion pipe connector 22 and the bellows main body 10 is filled up, the sealing performance is improved, and leakage is avoided. A first filter screen 222 is arranged on the inner side wall of one extension pipe interface 22, and a second filter screen 223 is arranged on the inner side wall of the other extension pipe interface 22. The diameter of the first filter screen 222 is larger than that of the second filter screen 223, the first filter screen 222 and the second filter screen 223 are partially arranged in a staggered manner, and the first filter screen 222 and the second filter screen 223 are partially movably sleeved. The filter screen assembly 222 can filter sharp objects such as stones, thereby reducing the damage of the sharp objects to the elbow 21, avoiding the leakage and other conditions of the elbow 21, prolonging the service life, and not causing interference to the action of the elbow 21. The end of the extension tube interface 22 away from the elbow 21 is also provided with a second connection 23. The second connecting portion 23 includes a second flange 231 and a plurality of second mounting holes 232 spaced apart from each other on the second flange 231. The second mounting holes 232 are circumferentially spaced along the outer sidewall of the expansion pipe joint 22. It is conceivable that the first flange 11 and the second flange 231 have the same structural size, and the number, positions and specifications of the first mounting holes 111 and the second mounting holes 231 correspond to each other. The first connecting portion 11 and the second connecting portion 23 may be connected and fixed by a screw connection.

The first filter 222 and the second filter 223 are respectively connected to the second connection portion 23 through a filter mounting ring 224, so that a certain gap is formed between the first filter 222 and the second filter 223 and the extension tube connector 22.

Compared with the prior art, the utility model provides a double-walled bellows with flexible pipe passes through elbow 21 makes and can connect with suitable angle between the double-walled bellows, time and human cost when reducing the installation. The filter screen 222 arranged at the end of the extension tube connector 22 can filter sharp objects such as stones, and prevent the inner wall of the corrugated ring 211 of the elbow 21 from being damaged. And the extension pipe 20 can also be used for keeping more allowance when the double-wall corrugated pipe is connected with an external interface by stretching the extension pipe, so that the construction efficiency is improved.

The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention, and any modification, equivalent replacement or improvement within the spirit of the present invention is encompassed by the claims of the present invention.
