Preferably, the second sealing member is an O-ring. After the installation inserts and the oil drain hole are assembled, the metal material which is solidified after melting can play a certain sealing role, but because the liquid metal can flow, the metal which is solidified after the solidification and has a connecting function can be distributed unevenly along the circumferential direction of the installation inserts, the reliability of the sealing function which leads to the pure relying on the solidified metal cannot be effectively ensured, and the second sealing piece is arranged between the installation inserts and the oil drain hole in the application, so that the oil leakage phenomenon can be effectively avoided.
Preferably, the distance between the groove bottom of the sealing groove and the oil drain hole wall is smaller than the section diameter of the second sealing element, and the groove width of the sealing groove is larger than the section diameter of the second sealing element. The second sealing element is an O-shaped sealing ring, and the purpose of the design is to ensure that the second sealing element is completely attached to the hole wall of the oil drain hole and the groove bottom of the sealing groove after being pressed, so that effective and firm sealing is formed.
Preferably, the mounting insert is made of a metal material such as copper. The installation insert and the oil drain hole are assembled through a high-frequency hot plugging technology, so that the melting point of a preparation material of the installation insert cannot be too high and needs to have good wear resistance, and metal materials such as copper are selected for preparation on the basis.
To sum up, the utility model discloses following beneficial effect has: (1) the problem of oil leakage caused by repeated dismounting and mounting of the bolts can be effectively solved; (2) the oil pan bolt assembly is simple in structure and convenient to install; (3) the metal that solidifies after the cooling can realize the fixed connection of installation inserts and oil drain hole, and both connect firmly and can play certain sealed effect after the assembly is accomplished.
