Description
Technical Field
The invention relates to the technical field of engine cooler connecting pipe joints, in particular to a reverse integrated connecting pipe joint for an engine oil cooler.
Background
In the prior art, the water pipe is connected with the engine oil cooler through the connecting pipe, the connecting pipe is sleeved in the water pipe and is sealed through the sealing ring, and the connecting pipe is connected with the engine oil cooler through the flange and the bolts and is firm. During assembly, the water pipe and the connecting pipe are firstly installed on the engine, then the engine oil cooler is pre-installed on the engine, and then the engine oil cooler is connected with the connecting pipe. Therefore, most of peripheral parts are assembled on the engine, the space for adjusting the installation angle of the connecting pipe is reserved to be narrow, the installation angle of the connecting pipe cannot be adjusted when the engine oil cooler is positioned at the pre-installation position, the connecting pipe can be adjusted to be approximately positioned only when the engine oil cooler is not installed, and then the engine oil cooler is positioned at the pre-installation position. In order to align the through hole of the connecting pipe with the screw hole of the oil cooler, a bolt is screwed in to finish the installation, and sometimes the angle of the connecting pipe is required to be adjusted after the oil cooler is disassembled for a plurality of times; greatly affecting the mounting tact. Meanwhile, in a high-power engine, more important is that the engine vibrates relatively more, meanwhile, shock waves are generated in fluid in a pipeline when a pump in the pipeline is started and stopped, loosening or liquid leakage at a joint can occur over time, the reliability of the engine is seriously affected, and even serious consequences are caused if the phenomenon is not found in time.
The foregoing background is only for the purpose of facilitating an understanding of the principles and concepts of the invention and is not necessarily in the prior art to the present application and is not intended to be used as an admission that such background is not entitled to antedate such novelty and creativity by the present application without undue evidence prior to the present application.
Disclosure of Invention
The invention provides a reverse integrated pipe joint for an engine oil cooler, which is difficult to loosen, convenient to install and good in use effect.
In order to achieve the above purpose, the invention adopts the following technical scheme:
a reverse integrated pipe joint for an engine oil cooler comprises a joint body and a cooler connecting pipe; the joint body comprises an inner joint and a compression outer sleeve; the left end of the inner joint is provided with a plurality of expansion strip-shaped openings, and the inner cavity of the left part is provided with a limit ring; a limiting table is arranged in the inner cavity at the right end of the inner joint and is connected with the cooler connecting pipe; the outer wall of the left end of the cooler connecting pipe is provided with a convex ring, and the outer wall of the left side of the cooler connecting pipe is provided with a round table; the convex rings are distributed on the inner side of the limiting table; a thread ring is arranged on the outer wall of the middle part of the inner joint; the middle part of the inner wall of the compaction outer sleeve is provided with threads in a matching way with the thread ring; the right end of the rotary table is provided with a horn mouth type reverse pushing table corresponding to the rotary table; the horn mouth type reverse pushing table is covered outside the round table; the outer wall of the round table and the horizontal line form an acute angle a; the inner wall of the horn mouth type reverse thrust platform and the horizontal line form an acute angle b; and +.a is greater than +.b.
Further, a gasket is further arranged at the convex ring of the cooler connecting pipe.
Furthermore, the left outer wall of the inner joint is also provided with a round table convex structure.
Furthermore, the left end inner cavity of the pressing outer sleeve is correspondingly arranged to be micro-horn-mouth-shaped.
Further, a gasket is further arranged at the limit ring.
Further, an arc-shaped convex ring is arranged on the outer wall of the right end of the water pipe connected with the left end of the inner joint.
Further, the outer pipe wall of the outer pressing sleeve is of an outer hexagonal structure.
Compared with the prior art, the invention has the beneficial effects that: the reverse integrated pipe joint and the cooler connecting pipe are integrally processed, after the water pipe, the engine oil cooler and other parts are installed, a left end of the water pipe is inserted into the left end of the inner joint in a reserved narrow space, then the inner joint is clamped and fixed by a tool (a clamp provided with clamping strips matched with the expansion strip-shaped opening can be correspondingly clamped into the expansion strip-shaped opening) so as to prevent the inner joint from rotating, then the tool is used for rotating and pressing the outer sleeve, the outer sleeve is pressed and moved leftwards, the left end of the inner joint is contracted inwards, the right end of the extruded water pipe is extruded by rightward pressure, and then the limiting ring is tightly attached; meanwhile, the outer sleeve is pressed to move leftwards, and the bell mouth type reverse pushing table at the right end of the outer sleeve is gradually pushed rightwards in the leftwards moving process because the angle a is larger than the angle b, and the convex ring is tightly pressed on the left side of the limiting table, so that the two ends can be tightened after one-time rotation tightening is realized. Meanwhile, the water pipe and the cooler connecting pipe connected by the reverse integrated connecting pipe joint are used, because the pressing force of the pressing outer sleeve on the water pipe depends on leftward extrusion force, and the pressing force on the cooler connecting pipe depends on rightward thrust force, vibration in all directions or shock waves of a pump can be effectively resisted in the daily use process of the engine, and the phenomenon of looseness is not easy to occur like a common joint, and the use effect is good.
