Description
Technical field
The utility model relates to pipeline field, in particular to a kind of bellows.
Background technique
Cable is generally embedded in underground, and there may be microorganisms in ground sweat and ground, if directly by cable burial
In underground, the crust of cable is easy to be corroded, and so as to cause conducting wire exposure and is damaged.
In the prior art, generally cable protection pipe can be set in cable jacket, cable is protected.And cable protection pipe is
One section, one section is mutually spliced to form entire protective conduit end to end, after being all arranged cable protection pipe outside all cables, then will
Protection pipe is filled.And the installation between the every section of cable protection pipe may be fixed by connector, or by cable protection pipe
One end be arranged to big opening, one end of the small opening of adjacent cable protection pipe and big opening grafting.
In the above-mentioned prior art, adjacent cable protection pipe is by being plugged in big opening end for small open end, only simply
Grafting is unable to ensure being connected and fixed between adjacent protection pipe, is easy to disengage.
Utility model content
It directly cannot ensure the deficiency being connected and fixed the purpose of the utility model is to overcome adjacent tubes in the prior art, and
A kind of bellows is provided, has achieved the effect that be connected and fixed between raising adjacent tubes.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of bellows, including tube body, the multiple protrusions being set on the outside of tube body, tube body includes protection section, connection insertion
The linkage section of section and protection section, the cross-sectional area of inserting paragraph are greater than the cross-sectional area of protection section, and the protection section offers
Internal screw thread and external screw thread, the internal screw thread are set to protection section close to the inner wall of inserting paragraph one end, and external screw thread is set to protection
Outside wall surface of the section far from inserting paragraph one end；The internal screw thread of tube body and the external screw thread of adjacent tubes cooperate.
By adopting the above technical scheme, the internal screw thread of the external screw thread of a section tube body and adjacent section tube body is subjected to screw thread company
It connects, realizes the connection and fixation of adjacent tubes；Threaded connection, which is that one kind is widely used, to be removably fixedly connected, and has structure
Simply, connection is reliable, the advantages that being convenient to mount and dismount.
Further preferably are as follows: the one end of the protection section far from inserting paragraph is construction section, and protrusion is located at protection section and insertion
The outer surface of section；External screw thread is located on construction section.
By adopting the above technical scheme, due to being provided with protrusion on the outside of bellows, the spiral shell between adjacent tubes may be will affect
Line open up and mutual threaded connection；So one section of construction section is arranged, it is not provided with protrusion on construction section, facilitates opening for screw thread
And if the threaded connection with adjacent tubes.It only uses construction section when installation to be installed, reducing convex outer surfaces may be to phase
The influence and interference that connection between adjacent tube body generates.
Further preferably are as follows: the caulking groove for abutting adjacent tubes construction section is offered in the protection section, internal screw thread is opened
On caulking groove inner wall.
By adopting the above technical scheme, if construction section is directly abutted and is threadedly coupled with the inner wall of protection section, construction section
Thickness can occupy the volume in protection section, occupy the space for placing cable, if the space in protection section is natively little, just
All conducting wires can be accommodated well, then the installation between adjacent tubes will encounter difficulties.After opening up caulking groove, by part construction section
Thickness reduces the occupancy to protection intersegmental part volume in caulking groove.
Further preferably are as follows: the thickness of the construction section and the depth of caulking groove are identical.
By adopting the above technical scheme, so that construction section is not take up the volume in protection section.
Further preferably are as follows: the ramp blocks abutted with linkage section inner wall are provided on the construction section.
By adopting the above technical scheme, when the thickness difference of construction section and protection section, it will appear spare region above construction section
Domain, and linkage section is to be obliquely installed, and is not easy to abut, after construction section is installed, it is likely that will lead to protection section one end with
The abutting of inserting paragraph line and face, contact area are small, it is easy to generate abrasion and damage.Inclination using ramp blocks, with linkage section
Face abuts, and increases contact area, reduces the generation of abrasion and damage.
Further preferably are as follows: described ramp blocks one end is abutted with protection section.
By adopting the above technical scheme, ramp blocks one end is connect with protection section, is avoided between occurring between protection section and ramp blocks
Gap, foreign matter are fallen into.
Further preferably are as follows: the sealing block abutted for the inserting paragraph inner wall with adjacent tubes is provided on the tube body.
By adopting the above technical scheme, inserting paragraph hollow part is filled using sealing block, on the one hand reduces soil and enters insertion
Section, is on the other hand that support is provided for inserting paragraph, reduces a possibility that inserting paragraph is by soil briquetting.
Further preferably are as follows: the protection section and the round and smooth connection of inserting paragraph.
By adopting the above technical scheme, reducing sharp edge may damage caused by tube body.
In conclusion the utility model has the following beneficial effects:
1, by setting internal screw thread and external screw thread, being connected and fixed for adjacent tubes is realized；
2, by setting construction section, the influence that protrusion may may cause the connection of adjacent tubes is reduced；
3, by setting caulking groove, construction section is reduced to the occupancy of protection intersegmental part volume, guarantees that conducting wire has sufficient space
It wears；
4, it by setting sealing block, on the one hand reduces soil and enters inserting paragraph, be on the other hand to provide support for inserting paragraph,
Reduce a possibility that inserting paragraph is by soil briquetting.
