Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to a high-pressure-resistant oil pipe joint. Background Art

[0002] Oil pipe joints are mainly used to connect water pipes, air pipes, gas pipes, etc., and play the role of sealing and connecting pipes;

[0003] When crimping the oil pipe joint, if the crimping amount is too small, the joint and the hose will be too loose, and the joint may come out of the joint under the action of oil pressure in the early stage of use. If the crimping amount is too large, the oil pressure will be too high, which will exert too much pressure on the interface of the oil pipe joint, resulting in leakage. If the joint and the hose are pressed too tightly, it is easy to cause local damage to the inner layer of the hose, resulting in cracks. The hydraulic oil will directly enter the steel wire layer from the crack, and then leak out along the gaps between the steel wires to the tail of the jacket, or continue to leak along the steel wire layer to accumulate somewhere, causing the outer layer of the rubber to bulge or even rupture.

[0004] Therefore, the present application provides a high-pressure resistant oil pipe joint to meet the demand. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the above-mentioned background technology and to propose a high-pressure-proof oil pipe joint.

[0013] Preferably, the reinforcement is in the shape of a hexagonal prism, and the interior of the reinforcement is hollow.

[0014] Preferably, the end corners of the reinforcement are connected with connecting pieces, and the connecting pieces are in the shape of rectangular strips, and six groups of trapezoidal cavities are formed between the reinforcement, the connecting pieces and the connecting pipes.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, a reinforcement is provided inside the connecting pipe. The reinforcement is in the shape of a hexagonal prism and is hollow inside.
