Description

Technical Field

[0001] The utility model relates to the field of drainage, in particular to the technical field of drainage pipes, and specifically refers to an annular connecting piece. Background Art

[0002] The drain pipe is an important component in the waterproof system for collecting and discharging water. The water is collected in the drain pipe through the water inlets on both sides of the drain pipe for collection and discharge. The drain pipe is widely used in projects such as sponge cities.

[0003] Since the plane shape of drainage pipes is often irregular, not square, and varied, on the one hand, it is difficult for rigid straight drainage grooves to completely cover the irregular positions of the planting roof (for example, curved edges); on the other hand, there are multiple connection angles between straight drainage grooves that are optimized according to the shape of the planting roof, which are difficult to meet the limited specifications of three-way drainage grooves or four-way drainage grooves, and there is a problem of difficulty in connecting straight drainage grooves. Therefore, the existing drainage grooves have the problem of single layout shape and connection form, which is difficult to meet the needs of complete coverage of the planting roof and rapid construction. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an annular connecting piece to meet the needs of completely covering a planting top plate and rapid construction.

[0005] The utility model is realized through the following technical scheme: a circumferential connector, comprising a pipe body, wherein the pipe body comprises a pipe head, a pipe body and a pipe tail, wherein the pipe body comprises a plurality of pipe segment units which are arranged in sequence and hinged in sequence, wherein the pipe head is hinged to the frontmost pipe segment unit, and the pipe tail is hinged to the rearmost pipe segment.

[0006] When the utility model is in use, since the pipe body includes a plurality of pipe section units that are arranged in sequence and hinged in sequence, adjacent pipe section units can rotate relative to each other, so that it is suitable for laying drainage pipes on edge terrains and the use of various layout shapes to meet the needs of completely covering the planting top plate and rapid construction.

[0007] Preferably, the pipe segment unit comprises an insertion segment and a plug-in segment connected in sequence, the insertion segment is inserted into the plug-in segment of the next pipe segment unit, the outer top surface / outer bottom surface of the insertion segment is fixedly connected with a hinge shaft extending upward / downward, and the inner bottom surface / inner top surface of the plug-in segment is provided with a hinge hole cooperating with the hinge shaft.

[0008] When this preferred solution is in use, the pipe segment units are arranged head to tail in sequence, and then the insertion segment of the rear pipe segment unit is inserted into the plug-in segment of the front pipe segment unit, and the hinge shaft is inserted into the hinge hole, thereby completing the hinge connection of the tails of several pipe segment units in sequence. After the insertion segment is inserted into the plug-in segment, the two ports of the two adjacent plug-in segments are arranged opposite to each other, and when the two plug-in segments rotate relative to each other, the two ports form a limit opening that limits the relative rotation angle of the two plug-in segments.

[0009] Preferably, the insertion section is fixedly connected to one end of the pipe head close to the pipe section unit, and the plug-in section is fixedly connected to one end of the pipe tail close to the pipe section unit.

[0010] This preferred solution facilitates connection with the pipe section unit by providing a pipe head and a pipe tail.

[0011] Preferably, the top plate and bottom plate of the plug-in section are adapted in shape, and two end surfaces of the top plate of the plug-in section are arc surfaces adapted to each other.

[0012] This preferred solution avoids interference between the two plug-in sections when the two plug-in sections rotate relative to each other by setting the arc surface, and at the same time reduces the gap between the two plug-in sections, thereby ensuring the supporting strength of the two pipe section units at the plug-in point.

[0013] Preferably, in one pipe segment unit, a through hole is provided on a side surface of the plug-in segment, and the through hole extends in a direction away from the insertion segment and extends to a port of the plug-in segment.

[0014] When this preferred solution is in use, the relative rotation angle of two adjacent pipe section units is increased by setting the through holes, so as to facilitate adaptation to more curved edge terrains and various layout shapes of drainage pipes.

[0015] Preferably, the outer side of the plug-in section is further provided with criss-cross reinforcing ribs.

[0016] This preferred solution facilitates enhancing the strength of the pipe section unit by providing reinforcing ribs.

[0017] The beneficial effects of the utility model are as follows: since the pipe body includes a plurality of pipe segment units which are arranged in sequence and hinged in sequence, adjacent pipe segment units can rotate relative to each other, so that it is suitable for laying drainage pipes on edge terrains, and for the use of a variety of arrangement shapes, meeting the needs of complete coverage of the planting top plate and rapid construction; the pipe segment units are arranged head to tail in sequence, and then the insertion section of the rear pipe segment unit is inserted into the plug-in section of the front pipe segment unit, and the hinge shaft is inserted into the hinge hole, so as to complete the hinge connection of the tails of the plurality of pipe segment units in sequence, and after the insertion section is inserted into the plug-in section, the two ports of the two adjacent plug-in sections are arranged relative to each other, and when the two plug-in sections rotate relative to each other, the two ports form a limit opening for limiting the relative rotation angle of the two plug-in sections.
