Description
Technical field
The utility model relates to a kind of fuel tank cap, the specially fuel tank cap of motorcycle.
Background technique
In the prior art, the upper cover and lower cover of the fuel tank cap of motorcycle are shaped by iron plate pressing and bending, and the two welds structure
At fuel tank cap entirety, the head that lower cover has hollow mounting portion and is fixedly connected with upper cover, hollow mounting portion is built-in with spring
Locking member realizes that the sealing cover of fuel tank cap and reservoir port closes.To prevent the oil gas in fuel tank through hollow mounting portion and upper and lower covers gap
Leakage requires height to welded seal technique between upper cover and lower cover, to reduce technology difficulty, and is folded between upper and lower cover
Inner cover, which is realized, closes the open end sealing cover of hollow mounting portion, avoids oil gas from leaking, allows for the increasing of fuel tank cap component parts in this way
More, assembly process becomes more cumbersome；On the other hand, metal oil case lid need to make it in one layer of Environmental-protection color zinc of electroplating surface after weld formation
Energy durable is prevented getting rusty, and improves the manufacturing cost of fuel tank cap.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of upper cover and lower cover is rubbing for environmentally-friendly plastic material
Motorcycle fuel tank cap.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of motorcycle oil tank lid, including upper cover and lower cover, the lower cover have the mounting portion that cooperation is screwed with reservoir port
And the head being fixedly connected with upper cover, the mounting portion is hollow, and interior to be equipped with spring, mounting portion side wall is provided with through hole, positions
Item is located in the spring and through hole across the through hole and can slide up and down in through hole, the upper and lower cover
It is plastic cover, the upward base wall of lower cover head top surface extends welding bar, and lower cover passes through welding bar and upper cover bottom wall
Rotation sweat soldering realization is fixedly connected with upper cover.
The upper cover bottom wall extends downwardly out the step rotation sweat soldering that reinforcing rib and the welding bar side wall are equipped with.
The lower cover head edge extends to form outer ring wall surface to upper and lower ends, and the upper cover inner sidewall is equipped with described in fitting
The convex ribs of outer ring wall surface.
The beneficial effects of the utility model are: the upper cover of the utility model and lower cover are all made of plastic material injection molding,
Simple process and antirust surface treatment is carried out again, substantially reduce production cost；The bottom wall of upper cover and the welding bar of lower cover pass through heat
Fusion welding is integrated, good airproof performance, to eliminate the inner sealing part in original fuel tank cap, is simplified assembly process, is improved
Production efficiency.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of the utility model；
Fig. 3 is the fractionation schematic diagram of the utility model.
Specific embodiment
Referring to figs. 1 to a kind of fuel tank cap of Fig. 3, including upper cover 1 and lower cover 2, lower cover 2, which has, screws cooperation with reservoir port
Mounting portion 21 and the head 22 being fixedly connected with upper cover 1, mounting portion 21 is hollow, interior to be equipped with spring 4, and 21 side wall of mounting portion is provided with
Through hole 23, on positioning strip 3 is located in spring 4 and through hole 23 and can be in through hole 23 across the through hole 23
Lower slider, upper and lower cover are plastic cover, and welding bar 24, lower cover 2 are extended to 1 bottom wall of upper cover in 2 head of lower cover, 22 top surface
Being fixedly connected for sweat soldering realization and upper cover 1 is rotated by welding bar 24 and 1 bottom wall of upper cover.
The upper cover 1 and lower cover 2 of the utility model are all made of environmentally-friendly plastic material injection molding, without passing through punching as metalwork
The multiple working procedures such as the curved, plating of backfin, are greatly saved production cost；The bottom wall of upper cover 1 and the welding bar 24 of lower cover 2 pass through rotation
Sweat soldering is integrated, good airproof performance, to eliminate the inner sealing part in original fuel tank cap, is simplified assembly process, is mentioned
High efficiency.
As a preferred embodiment of the present invention, 1 bottom wall of upper cover extends downwardly out reinforcing rib 11 and sets with 24 side wall of welding bar
Some steps 25 rotate sweat soldering, realize dual-seal, are further ensured that the leakproofness of upper cover 1 Yu lower cover 2.
Further, 2 head of lower cover, 22 edge extends to form outer ring wall surface 26 to upper and lower ends, and 1 inner sidewall of upper cover is equipped with
The convex ribs 12 of outer ring wall surface 26 are bonded, the bottom wall of upper cover 1 and the welding bar 24 of lower cover 2 pass through spin friction sweat soldering, welding
When a large amount of welding slag can be discharged, intercepted in lid by outer ring wall surface 26 and 12 welding slag of convex ribs, avoid welding slag exposed, influence oil
The appearance of case lid；The lower end that outer ring wall surface 26 extends forms the installation position of sealing ring 5.
