Embodiment Construction

[0010] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0011] As shown in the accompanying drawing, an engine oil pan heating tube installation structure includes a tube fitting body 3 installed on the side wall hole of the oil pan 1, and a heating tube 2, and the heating tube 2 runs through the tube fitting body 3 The inner hole is also extended, and the extended end of the heating tube 3 protrudes out of the tube joint body 1 and can be fixedly connected with the rubber tube. An annular groove 9 is arranged on the outer circular surface of the extending end of the heating pipe 2, and the rubber hose is clamped at the groove 9 on the extending end through a clamp. The tube joint body 3 is fixed on the side wall of the oil pan 1 through the hex nut 7, and a composite sealing gasket 8 is used on both sides of the side wall of the oil pan 1 to seal the oil in the oil pan 1, an...

Abstract

An engine sump heating pipe installation structure comprises a clamping sleeve connector body and a heating pipe which are installed in holes in the lateral wall of a sump, the heating pipe penetrates an inner hole of the clamping sleeve connector body and stretches out, and the stretching end of the heating pipe stretches out of the clamping sleeve connector body to be fixedly connected with a rubber pipe. The installation structure is simple, reasonable in design and low in installation and assembly difficulty. The installation structure has the advantages of being capable of transferring the leakage point of water in the heating pipe and transferring water leakage which may happen in the sump out of the sump. Even if the leakage happens, no water exists in engine oil in the sump, heating performance is not affected, safety operation of an engine is guaranteed, and the engine damage risks are reduced.

Description

technical field [0001] The invention relates to an installation structure of a heating pipe of an engine oil pan. Background technique [0002] In the cold northern regions, a preheating pipe needs to be installed in the oil pan of the vehicle engine, which is connected to the external hot water pipeline through the nozzle connection structure, so that the hot water circulates between the preheating pipe and the external heating system to The engine oil is heated, thereby improving the cold start performance of the engine. The body of the heating pipe is fixed in the oil pan through a bracket, and the nozzle is connected to the external heating system through two round holes opened on the side wall of the oil pan 1 . The fixing of the nozzle is carried out by a ferrule-type pipe joint connection structure. Since the engine oil is heated with water as the medium, the sealing is very important, because once the seal is not good, water entering the engine oil will cause serio...
