However, the existing automobile corrugated pipe cannot realize quick connection with an external pipe body, welding is often required, most of the pipe bodies are unstable in connection, and the pipe bodies are inconvenient to mount and dismount by users, so that the whole pipeline connection efficiency is influenced; therefore, the existing requirements are not met, and the automobile corrugated pipe which is free of welding and convenient to install is provided for the requirements.
Disclosure of Invention
The invention aims to provide a welding-free automobile corrugated pipe, which solves the problem that the existing automobile corrugated exhaust pipe is difficult to assemble with an external pipe body.
In order to achieve the purpose, the invention adopts the technical scheme that:
the utility model provides an exempt from welded car bellows, includes car bellows body, wherein, the peripheral cover of bellows body is equipped with sealed cylinder net cover, the both ends cover of bellows body is equipped with cylindric connector, the connector extends sealed cylinder net cover's both ends, be provided with a plurality of logical grooves on the connector, the extending direction who leads to the groove with the extending direction of connector is unanimous, the one end that leads to the groove with the one end of connector is on the coplanar, the cover is equipped with separable snap ring on the connector, the connector inner wall still is provided with the packing ring, the internal diameter of packing ring with the external diameter phase-match of the external body of bellows.
Preferably, the other end of the through groove is arc-shaped.
Preferably, the net cover is a steel wire net cover, and meshes exist on the steel wire net cover.
Preferably, the through slots are not uniform in length.
Due to the application of the technical scheme, compared with the prior art, the invention has the following advantages:
the invention relates to a welding-free automobile corrugated pipe, which comprises a corrugated pipe body, wherein a sealing net sleeve is sleeved on the periphery of the corrugated pipe body, columnar connectors are sleeved at two ends of the corrugated pipe body, a plurality of vertical through grooves are arranged on the connectors, one end of each through groove starts from the end surface of one end of each connector, a separable snap ring is sleeved on each connector, the inner diameter of each snap ring can be adjusted at will, a gasket is arranged on the inner wall of each connector, the gasket is sleeved on the outer wall of an external pipeline of the corrugated pipe when in use, the connectors at two ends are sleeved after other external pipelines of an automobile, the snap rings are fixed, the fixation of an automobile exhaust pipe is realized, the traditional welding mode is avoided, the through grooves are arranged in a way which can enable the use range of the connectors to be wider, the connectors can be sleeved on the external pipeline with larger diameter, after the gaskets are added, under the condition that the snap rings are fixed, the external pipeline of the connection can be prevented from being broken to the maximum extent.
