Description

Fuel lid

Technical field

The utility model relates to a kind of lid, relates in particular to a kind of fuel lid.

Background technology

No. 200820230765.4 Chinese patent discloses " a kind of floater spiral type oil level indicator ", the groundwork of this patent is: owing to being subject to the buoyancy of fluid, the position of float is affected by oil level, when float moves, float drives screw rod to rotate by the guide frame between float and screw rod, and drive oil level pointer to move by screw rod, by observing the position of oil level pointer, can indirectly know remaining oil mass in fuel tank;

Contriver finds this patented technology after the technical scheme of aforementioned patent is analysed in depth, and there are the following problems: if the structure of screw rod adopts the flight structure of simple one chip, its rigidity is poor, can only adopt the metallic material that hardness is larger to make guarantee structural stability, and because screw rod needs long period of soaking in fuel oil, therefore need the screw rod of metal material to carry out anti-corrosion treatment or adopt the metallic material of resistance to fuel oil corrosion to make screw rod, cause cost of manufacture higher.

Utility model content

For the problem in background technology, the utility model proposes a kind of fuel lid, its structure is: described fuel lid is comprised of lid, drive link (this drive link is similar to the function and efficacy of quoting the screw rod in patent as proof), float, U-shaped guide rail and oil level pointer; Lid bottom is connected with the open end of U-shaped guide rail; Float is arranged in U-shaped guide rail, is provided with and the chute of U-shaped guide rail on float sidewall, and float and U-shaped guide rail slide mutually; Float middle part is provided with pilot hole, and drive link is socketed in pilot hole, and drive link and float are in transmission connection; Drive link top and lid are rotationally connected, and drive link lower end and U-shaped guide rail are rotationally connected; Lid upper end is provided with groove, and oil level pointer is arranged in groove, and slot opening place is coated with transparent material; Oil level pointer is connected with drive link upper end; Described drive link is comprised of 3 guide ridges; Guide ridges extends axially along drive link in one-way spiral mode, is provided with the guide frame mating with guide ridges on pilot hole inwall.

In aforementioned schemes, be that from the different of prior art maximum drive link adopts the structure of 3 guide ridges, its benefit has: because the quantity of guide ridges has obtained increase, the structural strength of drive link is also improved thereupon, from the angle that improves structural strength, consider, under identical material condition, structural strength of the present utility model is better than prior art, from the angle reducing costs, consider, adopt after structure of the present utility model, even if adopting general rigid plastic makes, also can guarantee that drive link possesses good structural strength, thereby reduction material cost, save the operation of anti-corrosion treatment.

For the ease of making and improving structure aesthetics, the utility model has also proposed following preferred embodiment: same cross-section location place, 3 guide ridges are circumferentially uniformly distributed along drive link.

In aforementioned schemes, article two, the gap between guide ridges forms spiral guide groove, for the smoothness of assurance device action, should expand the cross-sectional plane of guide groove, for this reason, the utility model has also been done following improvement as far as possible: same cross-section location place, article two, the gap between guide ridges is fan-shaped, fan-shaped corresponding central angle is obtuse angle, thereby the width of guide ridges is tapered to end by root, so that the cross-sectional plane of guide groove is large as much as possible.

Be referred from prior art, on lid of the present utility model, be also provided with locking plate.

Be referred from prior art, on lid of the present utility model, be also provided with seal ring.

Useful technique effect of the present utility model is: improve the structural strength of screw rod, guarantee structural stability.
