First torque spring, the side opposite with hinged side are mutually fastened by clamping structure；The periphery of the connecting tube is equipped with and oil
The helicitic texture that case mouth matches, and the top for connecting pipe outer wall is arranged with the first sealing ring；The clamping structure includes setting
Buckle and setting button bit corresponding with buckle, the bolt that snaps through on top cover on bottom cover are hinged and connected to bottom cover
On, and the second torque spring is set on bolt.
Preferred: the top cover is equipped with air-breather, and the air-breather includes that top cap central position is arranged in
Venthole and the bolt being assemblied in venthole；The bottom end of the venthole side wall is equipped with bolt positive stop lug boss, sets on inner sidewall
There are vent grooves, the inner and outer of the vent grooves connection top cover.
Preferred: the top of the bottom cover is equipped with sealing card slot, is equipped with the second sealing ring in sealing card slot.
The utility model has the advantages that compared with prior art, the utility model is assemblied on reservoir port by connecting tube, top cover and bottom cover
Between by clamping structure fasten, switch it is very convenient；The setting of air-breather can prevent oil leak and trim tank and outer
The air pressure on boundary, to prevent tank pressure excessively high.
Detailed description of the invention
Fig. 1 is the schematic diagram of the section structure of the utility model；
Fig. 2 is the schematic diagram of the section structure of A-A in Fig. 1；
Fig. 3 is the present invention looks up structural representation of venthole described in the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Embodiment:
- Fig. 2 referring to Fig.1, the convenient fuel tank cap of switch described in the utility model, including top cover 1, bottom cover 2 and setting exist
The connecting tube 3 of 2 bottom end of bottom cover, the bottom cover 2 and connecting tube 3 are mold integrated formed structure.The periphery of the connecting tube 3 is set
There is the helicitic texture matched with reservoir port, and the top of 3 outer wall of connecting tube is arranged with the first sealing ring 6.The top of the bottom cover 2
End is equipped with sealing card slot, is equipped with the second sealing ring 11 in sealing card slot.The side of the top cover 1 and bottom cover 2 is hinged by bolt
It connects, and is set with the first torque spring 4 on bolt, the side opposite with hinged side is mutually fastened by clamping structure.The card
Binding structure includes the buckle 7 being arranged on bottom cover 2 and is arranged on top cover 1 and 7 corresponding button bits of buckle, the buckle 7
It is hinged and connected on bottom cover 2 by bolt, and is set with the second torque spring 8 on bolt.
The top cover 1 is equipped with air-breather, and the air-breather includes the venthole that 1 centre of top cover is arranged in
5 and the bolt that is assemblied in venthole 5.As shown in figure 3, the bottom end of 5 side wall of venthole is equipped with bolt positive stop lug boss 9, it is interior
Side wall is equipped with vent grooves 10, and the vent grooves 10 are connected to the inner and outer of top cover 1.
The working principle of the utility model is summarized as follows:
Fuel tank cap described in the utility model is by 3 Screw assembly of connecting tube in the reservoir port with vehicle during installation
Place.When needing to refuel, the tail portion of buckle 7 is pressed downwards, is detached from the button bit on its front end and top cover 1, top cover 1 loses buckle
7 locking effect automatically springs open under the elastic force effect of the first torque spring 4, at this point, refueling nozzle is inserted into connecting tube 3 i.e.
It can refuel；Oiling finishes, and extracts refueling nozzle, then pins top cover 1 with hand and fastens downwards, presses the button bit bottom of top cover 1
The cambered surface of 7 front ends of tight buckle, the button bit slide downward of top cover 1 while, push buckle 7 backward, when top cover 1 fastens in place, card
