Abstract
The utility model discloses a corrugated pipe for protecting an automobile wire harness, which comprises a corrugated pipe body, wherein metal reinforcing ribs are embedded in the inner sides of the convex parts of the outer wall of the corrugated pipe body, and flame-retardant rubber pipes are arranged between the adjacent convex parts on the inner wall of the corrugated pipe body. According to the corrugated pipe for protecting the automobile wire harness, the outer wall of the corrugated pipe body is coated with the flame-retardant coating, external flame retardance can be achieved, the flame-retardant rubber pipe is burnt through flame when the automobile wire harness is burnt inside, high-pressure dry powder filled in the flame-retardant rubber pipe is sprayed out to extinguish the fire, the interior is made to be flame-retardant, and therefore the corrugated pipe for protecting the automobile wire harness has the effects of internal flame retardance and external flame retardance, and the use safety is improved.
Description
Technical Field
The utility model relates to the technical field of corrugated pipes, in particular to a corrugated pipe for protecting an automobile wire harness.
Background
The corrugated pipe is a tubular elastic sensitive element which is formed by connecting foldable corrugated sheets along the folding and stretching direction. The corrugated pipe has wide application in instruments and meters, and is mainly used as a measuring element of a pressure measuring instrument to convert pressure into displacement or force. The corrugated pipe has thin pipe wall and high sensitivity, and the measurement range is from tens of Pa to tens of MPa. Its open end is fixed, its sealed end is in free state, and its elasticity is increased by using auxiliary helical spring or reed. When working, the pipe is extended along the length direction under the action of internal pressure, so that the movable end generates displacement in a certain relation with the pressure. The movable end drives the pointer to directly indicate the pressure. Bellows are often combined with displacement sensors to form pressure sensors that output an electrical quantity, sometimes also acting as isolation elements. The response speed of the bellows is slower than that of the bourdon tube because of the large volume change required for the expansion of the bellows. The bellows is adapted to measure low pressure.
The bellows is used in protection of current car wiring harness, and its compressive capacity is relatively poor, and easy extrusion deformation damages, also easily causes the manual extrusion of inside car wiring harness to damage, and secondly current bellows is used in protection of car wiring harness does not possess outside and inside fire-retardant function, so can not satisfy user's demand.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a corrugated pipe for protecting an automobile wire harness, which can be used for carrying out auxiliary support on a corrugated pipe body through the arrangement of a metal reinforcing rib, so that the compression resistance of the corrugated pipe is improved, and the internal automobile wire harness is prevented from being extruded and damaged.
In order to achieve the purpose, the utility model adopts the following technical scheme: the corrugated pipe for protecting the automobile wire harness comprises a corrugated pipe body, wherein metal reinforcing ribs are embedded in the inner sides of the protruding portions of the outer wall of the corrugated pipe body, and flame-retardant rubber pipes are arranged between the adjacent protruding portions on the inner wall of the corrugated pipe body.
As a further description of the above technical solution:
the two ends of the flame-retardant rubber tube are sealed structures, and high-pressure dry powder is filled in the flame-retardant rubber tube.
As a further description of the above technical solution:
the corrugated pipe body, the metal reinforcing ribs and the flame-retardant rubber pipe are of an injection molding integrated forming structure.
As a further description of the above technical solution:
and the outer wall of the corrugated pipe body is coated with a flame-retardant coating.
The utility model provides a corrugated pipe for protecting an automobile wire harness. The method has the following beneficial effects:
(1) this corrugated pipe is used in car pencil protection through the setting of metal strengthening rib, can carry out auxiliary stay by the bellows body, improves its compressive property, also prevents that inside car pencil from receiving the extrusion damage.
(2) This corrugated pipe for protection of automobile wire harness, corrugated pipe body outer wall coating has flame retardant coating, can carry out outside fire-retardant, through the setting of the flame retardant rubber pipe of inside setting for when inside automobile wire harness burns, burn out the flame retardant rubber pipe through flame, the high pressure dry powder blowout of flame retardant rubber intraductal intussuseption is put out a fire, makes inside fire-retardant, thereby makes this corrugated pipe for protection of automobile wire harness possess inside fire-retardant still outside fire-retardant effect, improves the security of its use.
