Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile parts and relates to an automobile oil cooler, in particular to a quick connector structure for an automobile oil cooler. Background Art
[0002] Automobile oil cooler, also known as oil cooler, is commonly used in automobile radiator, mainly for gearbox heat dissipation. Oil cooler is a device that accelerates the heat dissipation of lubricating oil to keep it at a lower temperature. Existing automobile oil cooler usually uses quick connector to connect the pipeline, and its structure must ensure sealing.
[0003] like Figure 1 A conventional automobile oil cooler is shown, Figure 2 The diagram of the installation structure of the oil cooler is shown below. The oil cooler is mainly composed of the oil cooler body, oil cooler joint, sealing ring, and quick joint. The quick joint is riveted with an elastic gasket. The automobile oil cooler is installed in the automobile radiator water chamber. After the quick joint is assembled, the elastic gasket is pressed against the sealing ring for sealing, and then the thread sealant is applied to seal and protect it to prevent loosening. The oil cooler quick joint structure has the following disadvantages:
[0004] 1. This structure seals the water chamber connection port by pressing the sealing ring with the spring gasket on the quick connector. Therefore, high processing accuracy is required for the connector. If the spring gasket is deformed or not pressed tightly, it is easy to leak, and the sealing performance needs to be improved.
[0005] 2. The height of the H position needs to be considered when assembling the oil cooler. The design wall thickness of the water chambers produced by different manufacturers is often different. When the design wall thickness of the water chamber is different, the step height of the oil cooler joint needs to be changed to ensure the sealing effect. It is necessary to process joints of various sizes, and the adaptability is low.
[0006] Based on this, a quick connector structure for an automobile oil cooler is designed which has good sealing effect and is applicable to water chambers with different wall thicknesses. Utility Model Content
