Sealing ring (not shown) is included, sealing ring is arranged between the branch pipe 110 of pipeline 101 and first.The setting of sealing ring, makes pipeline
101 and first connect between branch pipe 110 it is even closer.
Further, sealing ring can be the material with certain water imbibition, such as the polyethylene glycol of polyurethanes or poly-
Ether dihydric alcohol.Polyethylene glycol, polyether Glycols have certain expansion rate of water absorption.
Hydrophilic radical or material containing sufficient amount in polyethylene glycol, polyether Glycols, when it is contacted with water, moisture
Son can be entered inside it by adsorption, capillarity and diffusion etc., with the parent in polyethylene glycol or polyether Glycols
Water base group forms extremely strong adhesion, and with being continuously increased for hydrone, sealing ring expands deformation.Sealing ring is arranged at pipe
Between the branch pipe 110 of road 101 and first, after the part water in sealing ring extraction duct 101, sealing ring is in anti deformational force and osmotic pressure
When reaching balance, sealing ring keeps relative stability.Sealing ring makes to connect between the branch pipe 110 of pipeline 101 and first even closer
Meanwhile the first branch pipe 110 will not also be burst.
It is understood that in other embodiment of the present utility model, sealing ring can also be other materials, such as rubber
Glue, polyethylene, polypropylene etc..
It is understood that in other embodiment of the present utility model, sealing ring can also be arranged at pipeline 101 and
Between two branch pipes 120, or sealing ring is arranged between the branch pipe 130 of pipeline 101 and the 3rd.Further, multi-directional rotation limits
The three-way connection structure 100 of position formula can also include two sealing rings or three sealing rings, and two sealing rings are alternatively set
In the first branch pipe 110, the second branch pipe 120, the 3rd branch pipe 130 it is any both between pipeline 101.Correspondingly, three it is close
Seal ring is respectively arranged between the first branch pipe 110, the second branch pipe 120, the 3rd branch pipe 130 and pipeline 101.
Fig. 4 is the limit-type visual angle of three-way connection structure 100 second of the multi-directional rotation of the utility model embodiment offer
Structural representation, refer to Fig. 4.
In other embodiment of the present utility model, length direction of the pipeline 101 along pipeline 101 is provided with multiple limited blocks
102.In use, may exist and the length of pipeline 101 is changed.For example, disconnected from the centre position of pipeline 101,
To reduce the length of pipeline 101, the setting of multiple limited blocks 102, pipeline 101 after disconnection can preferably with multi-directional rotation
Limit-type three-way connection structure 100 is attached matching.
Second branch pipe 120 or the 3rd branch pipe 130 and the annexation of pipeline 101 and attachment structure and the first branch pipe 110 with
The annexation of pipeline 101 is identical with attachment structure.Correspondingly, the first chute 111, the second chute 121 and the 3rd chute 131
Set-up mode is identical, and is arranged at the limited block 102 of pipeline 101 with being arranged at pipeline 101a limited block 102 and being arranged at
The structure of pipeline 101b limited block 102 is also identical.It is understood that in other embodiments, the structure of above-mentioned three with
And the annexation of three can also differ.
In other embodiment of the present utility model, the limit-type three-way connection structure 100 of multi-directional rotation can also wrap
Connector (not shown) is included, it is any that the first branch pipe 110, the second branch pipe 120 and the 3rd branch pipe 130 are stretched out in connector connection
The limited block 102 of two.In other words, pipeline (101,101a, 101b) and the first branch pipe 110, the second branch pipe 120 and the 3rd
Pipe 130 connects, and being arranged at the limited block 102 of pipeline (101,101a, 101b) has part to stretch out outside branch pipe, and connector will stretch out branch
Two limited blocks 102 outside pipe are attached, and fetter the slip of limited block 102.In other embodiments, connector will can also be stretched
Three limited blocks 102 gone out outside branch pipe are attached.Limited block 102 is attached by connector, avoids limited block 102 from existing
Slided in chute, reduce abrasion of the limited block 102 to chute, the limit-type three-way connection structure 100 of increase multi-directional rotation
Service life.
In detail, connector can be flexible fixed strip (such as nylon rope or steel wire rope etc.), and connector can also be
The connection ring, elastic rubber ring etc. of elasticity.
The major advantage for the limit-type three-way connection structure 100 of multi-directional rotation that the utility model embodiment provides exists
In：
Pipeline 101 is provided with limited block 102, and the first branch pipe 110, the second branch pipe 120 and the 3rd branch pipe 130 are provided with
