[0002] Tank trucks, simply put, are specialized vehicles with sealed tanks as their core transport device. They are widely used for transporting special-form goods such as liquids, gases, and powders. Their core design focuses on safety and media adaptability. The material and structure of the tank directly determine what it can transport, while compliance is a fundamental prerequisite for its use on the road. During transportation, the tank's inlet needs to be sealed. To ensure the sealing effect, sealing ring assemblies are used to seal any gaps.

[0003] However, existing easy-to-install tank truck foreign object blocking sealing ring assemblies have the following problems during use: Since the foreign object blocking sealing ring is generally fixed inside the feed inlet, it is very prone to deformation during installation, and fixing it with bolts is inconvenient, making the installation and fixation of the sealing ring assembly quite difficult. Therefore, a corresponding technical solution needs to be designed to solve these technical problems. Utility Model Content

An elastic plate is provided inside the first sealing ring. Two mounting through holes are symmetrically provided in the middle of the fixing top ring block. A plurality of fixing components are evenly arranged between the top of the fixed top ring block and the inner wall of the feed inlet. The fixing components include fastening studs and support columns. A rotating frame is provided between the bottom end of the support column and the fixed top ring block. A rotating tube is provided on one side of the top of the support column. A plurality of positioning pins are evenly arranged on the bottom of the fixed top ring block. A second sealing ring is installed on the bottom of the fixed top ring block.

[0006] In a preferred embodiment of this utility model, the tank body is fixed to the tank truck body, a sealing cap is installed on the top of the feed inlet, and a third sealing ring is placed at the connection between the feed inlet and the sealing cap.

[0007] In a preferred embodiment of this utility model, a plurality of positioning holes are evenly arranged on the fixing ring and the second sealing ring, the outer ring size of the filter screen cylinder is the same as the inner ring size of the fixing ring, and the filtration density of the filter screen is different at different positions.

[0008] In a preferred embodiment of this utility model, the cross-section of the fixed top ring block is I-shaped, the outer edge of the first sealing ring is attached to the inner wall of the feed port, the pulling ring column passes through the mounting through hole, and one end of the pulling ring column is integrally connected to the first sealing ring.

[0009] In a preferred embodiment of the present invention, the elastic plate is an open annular structure, the first sealing ring has a deformation groove in the inner ring located between the two pulling ring posts, the fastening stud is fixed on the inner wall of the feed inlet, and the rotating pipe thread is connected to the fastening stud.
