Problems solved by technology
Generally, the volume of the blow molding fuel tank is relatively large and the position of the fuel tank port is relatively high. During mass production, the supplier may cause the local wall thickness of the fuel tank port to be thin or the plane near the fuel tank port to be uneven due to various reasons such as insufficient feed material and insufficient inflation pressure, so that The seal installation structure of the fuel tank port cannot play the expected sealing effect, and the fuel tank will leak when the fuel tank is full of fuel and tilted
[0003] Due to the limitation of the assembly relationship of the actual parts of the vehicle, it is not possible to check the air tightness of the fuel supply system during partial assembly, and the roll detection can only be performed after the vehicle is off the assembly line with full fuel; when repairs are required, the front cover Parts, headlights, windshield, etc. will all be dismantled, the workload is heavy, and the exterior covering parts are easily scratched or even need to be replaced

Embodiment Construction
[0011] Such as Figures 1 to 2 As shown, an installation structure of a blow-molded fuel tank port for a motorcycle includes bolts 6 fixedly connected to the base of the fuel tank cover (not shown in the figure) 5, and the ends of the bolts 6 face the fuel tank port. The matching method is pressed into the positioning hole of the skeleton 2, and the skeleton assembly formed after the fitting is combined with the insert 1 through the injection molding process to form a whole. This structure can ensure that its wall thickness and surface flatness can meet the requirements, and then insert The integral insert fits securely to tank port 4.
[0012] Insert 1 is made of the same material as fuel tank port 4, which can ensure the tightness after assembly. The chamfer design on the edge of insert 1 prevents insert 1 from being pulled out under force during assembly, which improves assembly efficiency and assembly Quality, the metal stamping parts of the skeleton 2 ensure the installa...

The invention discloses an installing structure of a blow molding oil tank opening for a motorcycle. The installing structure comprises bolts fixedly connected with an oil tank cover base and furthercomprises an insert arranged in the oil tank opening. The tail ends of the bolts face the oil tank opening. The insert is provided with at least two holes including the fixed hole fixed to the oil tank opening and the airtightness detecting hole. An injection molding material of the insert is consistent with that of the oil tank opening, and the beveling angle for preventing the whole insert frombeing pulled out by force is set on the edge of the insert. The whole installing structure is simple and small in size, the overall airtightness is ensured, airtightness detection can be conducted ona fuel supply system before the product launches, and the product percent of pass is increased.
Description
technical field [0001] The invention relates to a blow molding fuel tank, in particular to an installation structure of a blow molding fuel tank opening for a motorcycle. Background technique [0002] Motorcycle is a kind of travel tool that is often used in daily life. In the structural layout of motorcycles, blow-molded fuel tanks are often used due to modeling design or space constraints. Generally, the volume of the blow molding fuel tank is relatively large and the position of the fuel tank port is relatively high. During mass production, the supplier may cause the local wall thickness of the fuel tank port to be thin or the plane near the fuel tank port to be uneven due to various reasons such as insufficient feed material and insufficient inflation pressure, so that The sealing installation structure of the fuel tank port cannot play the expected sealing effect, and the fuel tank will leak when the fuel tank is full and tilted. [0003] Due to the limitation of the a...
