Description

High strength is threading pipe for communication

Technical Field

The utility model relates to a pipe fitting technical field is used in underground communication cable, the installation of optical cable, especially relates to a high strength is threading pipe for communication.

Background

The structure of a common seven-hole plum blossom tube is shown in figure 1, and comprises six sub-tubes 1-1 which are arranged in a surrounding way, wherein the tube walls of every two adjacent sub-tubes in the six sub-tubes 1-1 are mutually crossed and fused to form a plum blossom ring, the plum blossom tube needs to be buried underground when in use, due to the porous combined structure, the integral structure of the plum blossom tube is not stable enough, the pre-buried depth is influenced, in order to enhance the structural strength of the air-hole plum blossom tube, a reinforced plum blossom tube appears later, as shown in figure 2, a first reinforcing tube 1-2 and a second reinforcing tube 1-3 are coated on the outer side of the six sub-tubes 1-1, a plurality of supporting ribs 1-4 are uniformly arranged between the first reinforcing tube 1-2 and the second reinforcing tube 1-3 along the circumferential direction, the supporting ribs 1-4 are arranged along the radial direction, the inner ends of the supporting ribs 1-4 are fused with the first reinforcing tube 1-2, the outer ends of the supporting ribs 1-4 are fused with the second reinforcing pipes 1-3, the corrugated pipes 1-5 are arranged on the outer sides of the second reinforcing pipes 1-3, and the wave troughs of the corrugated pipes 1-5 are fused with the second reinforcing pipes 1-3, so that the integral bearing strength of the reinforced structure is greatly improved, but a certain improvement space still exists: if the supporting ribs 1-4 are all arranged along the radial direction, the load presenting capability of the supporting ribs 1-4 for presenting the shearing force with a certain angle with the supporting ribs is poor, and the influence is larger along with the increase of the embedded depth.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to avoid prior art's weak point, provide a threading pipe is used in high strength communication to effectively solve the weak point that exists among the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a high strength threading pipe for communication, is including encircleing the six root canals that set up, and two double-phase adjacent sub-pipe walls fuse each other in the six root canals, enclose into quincunx circle, the outside of sub-pipe is provided with bearing structure including being provided with first reinforced pipe and second reinforced pipe between first reinforced pipe and the second reinforced pipe, the outside of second reinforced pipe is provided with the bellows, and the trough and the second reinforced pipe of bellows fuse, bearing structure's cross section is circumferential wave, and bearing structure's inboard trough fuses with first reinforced pipe, and bearing structure's outside crest and second reinforced pipe fuse.

Furthermore, 10-16 positions are arranged on the inner side wave trough and the outer side wave crest.

Further, the first reinforcing pipe is of a structure with smooth inner and outer surfaces.

Further, the second reinforcing pipe is of a structure with smooth inner and outer surfaces.

The above technical scheme of the utility model following beneficial effect has: the utility model discloses a change the bearing structure of traditional radial brace rod into annular wave structure, the shearing force that resistance that can be fine comes from all directions has further improved the holistic mechanical properties of threading pipe, has increased its pre-buried degree of depth, has prolonged life.
