13 can be driven to prevent pounding teeth continuous rotation；So that entire piping unit continuously moves down；So that pipeline is all
The soil enclosed is constantly rolled on the upside of pipeline；The impact force that can be subject to by the soil on the upside of pipeline with buffering pipe；Protection
Pipeline；Annular flexural pivot set is mounted on the inner headed face that connection structure one end is equipped on interior conduit by ball hinged supporting in the present invention
On；Annular hinged ball is installed on the periphery of intermediate conduit one end；One end of intermediate conduit passes through annular hinged ball and annular flexural pivot
Set is fitted in interior conduit；The other end of intermediate conduit is located on the inside of adjacent interior conduit；When integrated piping unit to
When lower mobile；The piping unit will misplace between adjacent piping unit；Piping unit adjacent at this time will press
Compel corresponding intermediate conduit；So that intermediate conduit is swung around annular flexural pivot set and annular hinged ball；It is to guarantee to be pounded that it, which is acted on,
When misplacing between piping unit and adjacent duct units；Liquid on the inside of two interior conduits being capable of smooth flow；The present invention
The effect of middle connection sliding block, slide block slot and link block is to prevent from being pounded pipeline when moving down；Pounded piping unit with it is adjacent
It is interfered between piping unit；Shaft is connected in the present invention and is linked and the effect of axis hole is prevents from being pounded piping unit and putting
It is interfered between adjacent duct units when dynamic.The anti-teeth of pounding that the present invention designs can be around teeth shaft axis after being pounded
It turns an angle；It is so that piping unit is more smooth during rolling up soil that it, which is acted on,.
When the pipeline that people are designed using the present invention；When pipeline is hit and rum point is located at anti-pound in teeth；?
Prevent that pounding teeth can swing around teeth shaft axis under the action of impact force；Prevent that pounding teeth swing will drive driving circular column turn
It is dynamic；Driving circular column rotation will drive 13 and prevent pounding teeth respectively around teeth shaft swing corresponding thereto；13 simultaneously
It is anti-pound teeth during the swing and just will drive integrated piping move down；So that the soil of pipeline is rolled on pipeline
Side；The impact force that can be subject to by the soil on the upside of pipeline with buffering pipe；Protect pipeline；When two adjacent anti-on pipeline
It pounds when being hit between teeth；Impact force can squeeze crushing block；So that crushing block moves down；Crushing block, which moves down, to be squeezed
Press pushing block；So that pushing block is around interior conduit center rotating certain angle；Pushing block rotation just will drive anti-circular column of pounding and turn
It is dynamic；Prevent pounding circular column rotation and just will drive preventing pounding teeth rotation；At this time impact force will move with to the crushing block phase being knocked
The anti-of neighbour is pounded in teeth；So that this anti-teeth of pounding is swung；Prevent that pounding teeth swing will drive driving circular column rotation；Drive circular column
Rotation will drive 13 and prevent pounding teeth respectively around teeth shaft swing corresponding thereto；Prevent that pounding teeth is swinging for 13 simultaneously
It just will drive integrated piping in the process to move down；So that the soil of pipeline is rolled on the upside of pipeline；By on the upside of pipeline
The impact force that can be subject to buffering pipe of soil；Protect pipeline.
