Description

Technical Field

[0001] The utility model relates to the technical field of engine oil return pipes, in particular to an engine oil return manifold. Background Art

[0002] The engine oil return pipe is mainly connected to the fuel distributor to return excess oil to the fuel tank or oil filter through the oil return pipe.

[0003] Most of the existing oil return manifolds are made of rubber and are installed in the oil return pipeline of the engine system by installing corresponding connection interfaces at each outlet. However, most of the existing oil return manifolds are exposed to the air after installation without any protection measures. When used in winter, the rubber material will become fragile and easy to break due to the material itself, which is prone to problems. In addition, when used, it will cause thermal oxidation aging due to contact with air, and its service life is relatively low. To this end, we propose an engine oil return manifold. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides an engine oil return manifold.

[0005] The technical solution adopted by the utility model to solve the technical problem is an engine oil return manifold, comprising a first protective tube, the surface of the first protective tube is rotatably connected with two sets of fine-tuning handles with different directions, the side wall of the fine-tuning handle is connected through a corrugated steel pipe, one end of the corrugated steel pipe away from the fine-tuning handle is fixedly connected with a connection port, and the top end of the first protective tube is connected through and fixedly plugged into the bottom end of a heat-conducting connection module;

[0006] The inner wall of the first protective tube is fixedly connected with an insulation sleeve, the center of the insulation sleeve is penetrated with a built-in oil return pipe, the side wall of the built-in oil return pipe is penetrated and fixedly connected with a branch oil pipe, and the branch oil pipe is penetrated and inserted into the interior of the corrugated steel pipe.

[0007] By adopting the above technical solution, by using a protective tube and an insulation sleeve to protect the built-in oil pipe, the return oil manifold can be protected from the rubber itself becoming less flexible and easy to break due to the low temperature in winter during use during winter and daily driving, and from being corroded by oxygen and causing thermal oxidation aging due to contact with air during daily use, which affects the service life. The service life of the return oil manifold can be extended, the maintenance cycle can be reduced, and the applicability can be improved.

[0008] Specifically, a second protection tube is passed through and fixedly inserted into the top end of the thermally conductive connection module, and a rotating connection tube is rotatably connected to the top end of the second protection tube.

[0009] By adopting the above technical solution, the built-in oil return pipe is protected by the first protection pipe and the second protection pipe, and the device is easily installed by the rotatable rotating connecting pipe.

[0010] Specifically, two groups of fine-tuning handles are rotatably connected to the surface of the second protection tube.

[0011] By adopting the above technical solution, the angle of the branch pipe can be fine-tuned by using the fine-adjusting handle configured in the same manner as the first protective tube to facilitate installation.

[0012] Specifically, a heating wall bin is fixedly connected to the side wall of the heat-conducting connection module, and a replaceable heating element for heating is installed inside the heating wall bin.

[0013] By adopting the above technical solution, the replaceable heating element can be used to ensure that the temperature of the internal pipeline is constant, thereby preventing the rubber from becoming brittle due to low temperature.

[0014] Specifically, the top end of the first protection tube is fixed and connected with a connecting hose.

[0015] By adopting the technical solution, the device is installed in the throttle of the engine through a connecting hose.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] The technical solution of the present application can make fine adjustments to the structural design of the front trunk of a car during installation through the structural design of the first protective tube, fine-tuning handle, corrugated steel pipe, heat-conducting connection module, second protective tube, rotating connection tube, heating wall bin, replaceable heating element, insulation sleeve, built-in oil return pipe and manifold oil pipe, so that the device can be installed in the oil return pipeline conveniently. When in use, the first protective tube, heat-conducting connection module, second protective tube, heating wall bin, replaceable heating element and insulation sleeve can be used to ensure that the surrounding ambient temperature of the oil return pipe is in a normal operating temperature environment in winter, so as to avoid the rubber pipe being easily broken due to low temperature.
