Problems solved by technology

[0005] In the prior art, the pipe body 1' is generally a seamless steel pipe, and the two ends of the seamless steel pipe are generally welded in the connecting sleeve 2'1. Since the seamless steel pipe is a rigid structure, it is not easy to bend or deform, and The two ends of the seamless steel pipe are respectively welded and fixed in the connecting sleeve 2'1, so when processing the seamless steel pipe, the accuracy of the processing technology must be very high, otherwise it is difficult to assemble on the engine
[0006] In addition, since the seamless steel pipe is a rigid structure, and its end is welded and fixed to the connecting sleeve 2'1, when the engine vibrates greatly, the welded part of the seamless steel pipe and the connecting sleeve 2'1 may be seamless. The weak point of the steel pipe is prone to cracking, which will cause oil leakage failure

Embodiment Construction

[0035] The core of the present invention is to provide a pressure oil pipe. The structural design of the pressure oil pipe can reduce the difficulty of its own processing technology on the one hand, and on the other hand can reduce the possibility of cracking due to engine vibration. In addition, another core of the present invention is to provide an engine including the pressure oil pipe.

[0036] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Please refer to image 3 with Figure 4 , image 3 It is a structural schematic diagram of the pressure oil pipe in an embodiment of the present invention; Figure 4 for image 3 Schematic diagram of structural decomposition of medium pressure tubing.

[0038] In the basic technical solution of the present invention, the p...

Abstract

The invention discloses a pressure oil pipe which comprises a pipe body (1) and a joint body (2), wherein the joint body (2) is provided with a connecting sleeve pipe (21), and the pipe body (1) is connected into the connecting sleeve pipe (21); an annular slot (211) is further drilled on the inner wall of the connecting sleeve pipe (21), and a first limiting part (31) and a second limiting part (32) are respectively arranged at both sides of the annular slot (211) along the axial direction; and a protruded part (11) is arranged on the circumferential outer wall of the pipe body (1), and the protruded part (11) is slidably arranged in the annular slot (211) along the axial direction and positioned between the first limiting part (31) and the second limiting part (32). Through the structural design of the pressure oil pipe, on one hand, the own processing process difficulty of the pressure oil pipe can be lowered, on the other hand, the cracking possibility of the pressure oil pipe along with the vibration of an engine can be reduced. In addition, the invention also discloses the engine comprising the pressure oil pipe.

Description

technical field [0001] The invention relates to the technical field of oil pipes, in particular to a pressure oil pipe. In addition, the invention also relates to an engine comprising the pressure oil pipe. Background technique [0002] In the engine field, the pressure oil pipe is a pipe connected to the lubricating oil circuit of the engine, and the pressure oil pipe is usually exposed outside the engine. [0003] Please refer to figure 1 with figure 2 , figure 1 It is a schematic structural diagram of a typical pressure oil pipe in the prior art; figure 2 for figure 1 Side view of medium pressure tubing. [0004] The pressure oil pipe in the prior art includes a pipe body 1' and a joint body 2', the joint body 2' is provided with a connecting sleeve 2'1, and the pipe body 1' is arranged in the connecting sleeve 2'1, and then passed through The hinged bolt connects the joint body 2' to the oil connection port of the engine. [0005] In the prior art, the pipe bod...
