2. the inner ring block is arranged between the pipe body and the conical head, the outer ring block is further arranged on the inner wall of the nut, the pressing ring is arranged between the outer ring block and the inner ring block, the contact surfaces of the pressing ring and the outer ring block and the contact surfaces of the pressing ring and the inner ring block are in the shape of a circular arc, when the contact surfaces on the two sides of the pressing ring are stressed, the circular arc structure can form an elastic supporting effect, and the nut is high in practicability, simple in structure and good in sealing effect;

3. through setting up and being equipped with reinforcing mechanism outside the body, this reinforcing mechanism is including setting up in a plurality of enhancement rings body outside the body and setting up in a plurality of connectors between two adjacent enhancement rings bodies, through strengthening ring body and cooperation connector, then forms good enhancement effect, and the practicality is strong, and structural strength is high.

Drawings

Fig. 1 is a structural diagram of an embodiment of the explosion-proof and leak-proof sealing high-pressure oil pipe of the present invention.

The reference numbers in the figure are 1-pipe body, 10-check ring, 101-first inclined plane, 2-pressing ring, 3-nut, 30-outer ring block, 4-conical head, 40-second inclined plane, 5-inner ring block, 60-reinforcing ring body and 61-connecting body.

Detailed Description

The embodiment of the explosion-proof and leak-proof sealed high-pressure oil pipe of the present invention is further described with reference to fig. 1.

The utility model provides an explosion-proof leak-proof sealed high pressure fuel pipe, including body 1, the clamp ring 2,
