Background

The high-pressure oil pipe is a component of a high-pressure oil circuit, the oil pipe is required to bear certain oil pressure and has certain fatigue strength, the sealing requirement of a pipeline is ensured, the vehicle high-pressure oil pipe mainly appears in a high-pressure injection diesel engine and a high-pressure injection gasoline direct injection engine and can bear the oil pressure required in the running process of the engine, the traditional high-pressure oil pipe is composed of a steel wire winding framework layer and inner and outer oil-resistant and corrosion-resistant synthetic rubber, and has a certain compression-resistant effect, but when the high-pressure oil pipe is impacted with high strength, the high-pressure oil pipe is still easy to damage.

SUMMERY OF THE UTILITY MODEL

The utility model provides a pair of protection type high pressure fuel pipe can solve high pressure fuel pipe and receiving the easy problem of damaging of high strength impact.

The utility model discloses a solve above-mentioned problem, the technical scheme who proposes is: including the high pressure fuel pipe body, high pressure fuel pipe body both ends are rotated respectively and are connected with coupling nut, the fixed cover in the high pressure fuel pipe body both ends outside is equipped with solid fixed ring, high pressure fuel pipe body outside cover is equipped with elastic bellows, elastic bellows inner wall evenly is equipped with a plurality of buffer blocks.

Preferably, the two ends of the elastic corrugated pipe are respectively fixedly connected with the fixing rings, the elastic corrugated pipe can play a certain protection role on the high-pressure oil pipe body, and the movement of the high-pressure oil pipe is not influenced.

Preferably, buffer block one side and elastic bellows inner wall fixed connection, opposite side and high pressure fuel pipe body outer wall fixed connection, buffer block and elastic bellows all can play the buffering effect to make high pressure fuel pipe be difficult to damage.

Preferably, the elastic corrugated pipe is made of rubber.

Preferably, the buffer block is made of rubber.

The utility model has the advantages that: the utility model discloses a setting of elasticity bellows and buffer block has played the buffering effect to the high pressure fuel pipe body, and is not fragile more when the high pressure fuel pipe body receives the high strength impact.
