Description

TECHNICAL FIELD

[0001] The utility model relates to the field of plastic pipeline, especially a plastic pipeline structure for communication cable laying. BACKGROUND

[0002] The grid pipe can also be called a grid format plastic pipe or a grid format communication pipe, and is mainly used for laying, guiding, isolating and protecting underground communication optical cables and cables. The grid pipe currently includes a four-hole grid pipe, a five-hole grid pipe, a six-hole grid pipe and a nine-hole grid pipe, and is an integrated structure made by using an integrated molding process. When laying and using, different grid pipes with different numbers of holes need to be selected according to different use scenarios.

[0003] It can be seen that the current grid pipe has poor laying flexibility. For example, when different numbers of pipes need to be used in the laying process, the entire pipe must be replaced, and the number of holes cannot be adjusted on site. There is also a situation that cannot be expanded later. For example, when the demand increases in the future, the entire pipe system may need to be replaced, and the number of holes of the existing grid pipe cannot be simply expanded.

[0004] Therefore, the utility model provides a plastic pipeline structure for communication cable laying, which adopts a combined pipeline structure. Different assembly structures can be adjusted according to different use requirements, so that the number of holes of the pipeline can be adjusted, and the technical effects of facilitating the pipeline laying process and facilitating the later adjustment can be achieved.

DETAILED DESCRIPTION

[0036] In order to facilitate the person skilled in the art understanding, the utility model will be described further in detail in conjunction with the drawings and examples below:

[0038] In the utility model, the pipeline main body is used for laying cables, and is formed by stacking nine sub-pipelines 1, and is square as a whole and fixed by the fixing assembly. The fixing assembly is attached to the outer side wall of the pipeline main body to fix the pipeline main body.

[0039] In the utility model, different sub-pipelines 1 in the pipeline main body can be used for laying different types of cables, so that different types of cables can be separated during cable laying, for example, power cables and communication cables can be laid through different sub-pipelines 1 respectively, which can effectively reduce the influence of power cables on communication cables.

[0040] In the utility model, the laying process of the pipeline main body is as follows: first, the sub-pipelines 1 are stacked together to form the pipeline main body, and then the fixing assembly is sleeved on the pipeline main body to fix the stacked sub-pipelines 1. The sub-pipelines 1 in the pipeline main body are independent of each other and do not have a connecting structure, and the fixing assembly sleeved on the pipeline main body is attached to the outer side wall of the pipeline main body to fix the pipeline main body. Therefore, the sub-pipelines 1 in the pipeline main body can be separated from each other and can be pulled out of the pipeline main body. Therefore, during laying of the pipeline, the number of sub-pipelines 1 in the pipeline main body (the number of sub-pipelines 1 in the pipeline main body is at most nine) can be selectively adjusted according to requirements, that is, when different numbers of holes are required in the laying process, the number of holes of the pipeline can be adjusted on site without replacing the entire pipeline, which can effectively improve the convenience of the pipeline laying process.

[0041] In addition, after the pipeline is laid, if it is required to increase the number of sub-pipelines 1 to increase the number of cables laid in the future, the number of sub-pipelines 1 can be increased on the existing pipeline main body (the sub-pipeline 1 to be increased is inserted into the fixing assembly and stacked with other sub-pipelines 1), without replacing the entire pipeline. It is worth noting that the number of sub-pipelines 1 can be increased only when the number of sub-pipelines 1 in the pipeline main body is less than nine.

[0042] In one embodiment, the outer side walls on both sides of the sub-pipe 1 are partially inwardly recessed to form a vertically arranged first mounting groove 11, the outer side walls on both sides of the sub-pipe 1 are partially inwardly recessed to form a second mounting groove 12, the second mounting groove 12 is arranged vertically to the first mounting groove 11 and is staggered with the first mounting groove 11; the first mounting grooves 11 on adjacent sub-pipes 1 are spliced together to form a first mounting hole, and the second mounting grooves 12 on adjacent sub-pipes 1 are spliced together to form a second mounting hole; the first mounting holes in the pipe body are spliced together to form a first fixed insertion hole 5, and the second mounting holes in the pipe body are spliced together to form a second fixed insertion hole 6; the fixing assembly is provided with a first via hole communicating with the first fixed insertion hole 5 at both ends corresponding to the first fixed insertion hole 5, and a second via hole communicating with the second fixed insertion hole 6 at both ends corresponding to the second fixed insertion hole 6; further comprising a first fixed rod 3 and a second fixed rod 4 embedded in the first fixed insertion hole 5 and the second fixed insertion hole 6, both ends of the first fixed rod 3 extend to the first via hole and are detachably connected with the first via hole, and both ends of the second fixed rod 4 extend to the second via hole and are detachably connected with the second via hole.

[0043] In this embodiment, when the sub-pipes 1 are stacked, the first mounting grooves 11 and the second mounting grooves 12 thereon need to be aligned with each other, at this time, the first mounting grooves 11 and the second mounting grooves 12 on the sub-pipes 1 will be spliced together to form first mounting holes and second mounting holes, and adjacent first mounting holes and second mounting holes will be spliced together to form first fixed insertion holes 5 and second fixed insertion holes 6, wherein the first fixed insertion holes 5 are vertically arranged, and the second fixed insertion holes 6 are horizontally arranged.

[0044] In this embodiment, the first fixed rod 3 is used to be inserted into the first fixed insertion hole 5 and the corresponding first via hole at the same time, at this time, the first fixed rod 3 is embedded in the first fixed insertion hole 5, and both ends of the first fixed rod 3 are detachably connected with the first via hole, therefore, the first fixed rod 3 can fix the sub-pipes 1 in the fixed ring in the horizontal direction, limit the movement of the sub-pipes 1 in the pipe body left and right, correspondingly, the second fixed rod 4 inserted into the second fixed insertion hole 6 can limit the movement of the sub-pipes 1 in the pipe body up and down, therefore, the existence of the first fixed rod 3 and the second fixed rod 4 can realize the fixation of the sub-pipes 1 in the pipe body, even if some sub-pipes 1 in the pipe body are removed, the displacement of the sub-pipes 1 in the pipe body can also be avoided.

[0045] Wherein, since the two ends of the first and second fixed rods 3 and 4 are detachably connected to the first and second through holes respectively, the fixing of the sub-pipes 1 can be released by detaching the first and second fixed rods 3 and 4 from the first and second through holes, at this time, the sub-pipes 1 can be pulled out from the fixing assembly to adjust the number of the sub-pipes 1 in the pipe body, and after reducing the number of the sub-pipes 1, the first and second fixed rods 3 and 4 are inserted into the original positions to continue to fix the sub-pipes 1 in the pipe body.

[0046] In addition, the two ends of the first and second fixed rods 3 and 4 embedded in the first and second fixed jacks 5 and 6 are connected with the first and second through holes to support the pipe body and the fixing assembly, and the existence of the first and second fixed rods 3 and 4 can also strengthen the structural strength of the pipe body.

At the same time, compared with the integrated structure, the first and second fixing rings 21 and 22 are separated from each other, the pipe body between the first and second fixing rings 21 and 22 has a certain length, thereby improving the fixing effect of the first and second fixing rings 21 and 22 and the first and second fixed rods 3 and 4 on the pipe body.

[0049] In one embodiment, the first fixing ring 21 is composed of two first half rings which are detachable, and the second fixing ring 22 is composed of two second half rings which are detachable.

[0050] In this embodiment, the first fixing ring 21 is composed of the first half rings, and the second fixing ring 22 is composed of the second half rings, so that when the first and second fixing rings 21 and 22 are sleeved on the pipe body to fix the sub-pipes 1, the first and second half rings can be combined, which is more convenient than inserting the sub-pipes 1 into the first and second fixing rings 21 and 22 in sequence to fix the sub-pipes 1 by the first and second fixing rings 21 and 22.

[0051] In one embodiment, the first mounting slot 11 and the second mounting slot 12 are semicircular in cross section, the first fixed rod 3 and the second fixed rod 4 are cylindrical, and the first fixed rod 3 and the second fixed rod 4 embedded in the first fixed insertion hole 5 and the second fixed insertion hole 6 are respectively arranged in abutment with the inner side surface of the first fixed insertion hole 5 and the second fixed insertion hole 6.

By making the diameter of the first fixed rod 3 and the second fixed rod 4 the same as the diameter of the first mounting hole and the second mounting hole, the first fixed rod 3 and the second fixed rod 4 inserted into the first fixed insertion hole 5 and the second fixed insertion hole 6 can be in abutment with the inner side wall of the first fixed insertion hole 5 and the second fixed insertion hole 6, which can avoid relative movement between the sub-pipes 1 and has good fixing effect. At the same time, the first fixed insertion hole 5 and the second fixed insertion hole 6 and the first fixed rod 3 and the second fixed rod 4 are all cylindrical, which can also facilitate the insertion operation of the first fixed rod 3 and the second fixed rod 4.

[0053] In addition, preferably, the first fixed insertion rod, the second fixed insertion rod, the first fixed insertion hole 5 and the second fixed insertion hole 6 have the same diameter, so that the first fixed insertion rod and the second fixed insertion rod can be used interchangeably, which can improve the convenience of pipeline laying to a certain extent.

[0056] In one of the embodiments, one end of the first fixed rod 3 is fixedly provided with a first abutting block 31; and one end of the second fixed rod 4 is fixedly provided with a second abutting block 41.

[0057] In the embodiment, the first abutting block 31 at the end of the first fixed rod 3 is used to abut against the outer surface of the fixed assembly to limit the displacement of the first fixed rod 3, and at the same time, the locking of the threaded connection structure between the first fixed rod 3 and the fixed assembly can be realized through the interaction force between the first abutting block 31 and the fixed assembly, and the strength of the connection structure between the first fixed rod 3 and the fixed assembly can be further increased, so that the structural stability of the pipeline body can be further increased; correspondingly, the second abutting block 41 on the second fixed rod 4 can also play a role in increasing the structural stability of the pipeline body.
