As Chinese utility model patent application application number: (201020257486.4) disclose a kind of fuel lid, by enclosing cover, valve rod, geared sleeve, inner cap, gear composition, its difference is that the middle part of inner cap is flexibly connected valve body, the lower end in the outside of valve body connects standby cap, in one end of standby cap upper end linking springs II, the other end of spring II is connected with inner cap, connect and stop up in the lower end of valve body, stop up by spring III and connect spool, spring III is positioned at the outside of spool, the upper end of spool is flexibly connected with valve body by rubber cushion II, outside in valve body upper end is connected with inner cap by rubber cushion I, thereby simple in structure, easy to use, safety, reliably, in the time that fuel tank is inverted or when machinery is overturned, fuel oil can not flow out in fuel tank, breather can compensate automatically to the pressure in fuel tank, be specially adapted to automobile, the uses such as trac..Above-mentioned fuel lid can play sealing process to fuel tank, and optimized fuel tank pressure compensated function in the process of moving, but in life process, automobile is often parked in outdoor spending the night, above-mentioned fuel lid is but difficult to prevent that in fuel tank, fuel oil is stolen, and safety performance is lower.
Summary of the invention
There are the problems referred to above for existing technology in the utility model, has proposed a kind of locking structure of vehicle fuel tank cap, and the locking structure of this vehicle fuel tank cap can effectively prevent that fuel lid is opened, and plays anti-theft function.
The purpose of this utility model can realize by following technical proposal: a kind of locking structure of vehicle fuel tank cap, described fuel lid comprises a cylindrical body, on described body outer peripheral face, there is outside thread, described reservoir port is tubular, on the inwall of reservoir port, there is negative thread, it is characterized in that, described locking structure comprises and on reservoir port inwall, circumferentially offers some through holes, described through hole axially and reservoir port radially consistent, in described through hole, slide and be inserted with a locating dowel pin, described locating dowel pin adopts ferrous material to make, on the lateral wall of described reservoir port, be arranged with an annular electromagnet, described electromagnet is relative with through hole, in described through hole, be also provided with spring, one end of described spring is pressed on the end face of locating dowel pin, the other end is pressed on electromagnet madial wall, on the lateral wall of described body, circumferentially offer some positioning grooves, described locating dowel pin is pressed in positioning groove, described electromagnet is also connected with the switch that can control magnet switching electricity.
Body is connected in oil filling port by screw thread fit, and after body is tightened, locating dowel pin is under the effect of spring force, and its end is pressed in positioning groove, can prevent body rotation, plays anti-theft function; Need to open body time, by the energising of switch control electromagnet, after electromagnet energising, produce magnetic force and adsorb locating dowel pin retraction through hole, after locating dowel pin departs from positioning groove, positioning action disappears, and body can screw out from oil filling port.
In the locking structure of above-mentioned vehicle fuel tank cap, described positioning groove is strip, the bar shaped direction of positioning groove with body shaft to consistent, the cross-sectional plane of described positioning groove is triangular in shape, and positioning groove has a cell wall radially arranging along body one and and is tangential on the cell wall two of body side face, described cell wall one is connected with cell wall two, and when the direction of a court of described cell wall unscrews with body, the direction of rotation is consistent.After electromagnet power-off, locating dowel pin is mortgaged on body, because the cell wall two of positioning groove is tangential on cup outer peripheral face, and when the direction of a court of cell wall unscrews with body, the direction of rotation is consistent, therefore body can screw under the compressing of locating dowel pin, and cell wall one radially arranges along body, therefore can not oppositely unscrew, easy to operate.
In the locking structure of above-mentioned vehicle fuel tank cap, described locating dowel pin has two, and the relative reservoir port axial line of these two locating dowel pins is symmetrical arranged.Make locating dowel pin even to the positioning action power of body.
In the locking structure of above-mentioned vehicle fuel tank cap, described positioning groove has four, and these four positioning grooves are circumferentially uniformly distributed along body.Making body screw rear locating dowel pin all can be pressed in positioning groove.
In the locking structure of above-mentioned vehicle fuel tank cap, it is indoor that described switch is arranged on vehicle drive, and switch is connected with electromagnet by electric wire.Avoid the outer personnel's touch switch of car, safe.
Compared with prior art, the locking structure of this vehicle fuel tank cap has the following advantages:
1, be arranged on the top of piston due to spring, piston is with obstruction by the isolation of spring also liquid, and therefore whole fluid process liquids all can not contact with spring, avoids spring and liquid generation chemical reaction.
2, because depression bar fits together by mutual sheathed being fixedly connected with between body, lower straight-bar and upper straight rod, connection cover is set on the pump housing, therefore total processing is convenient with dismounting.
3, in the form of annular discs owing to blocking, its edge upwards turns down, and when state of nature, this edge inserts in the groove of piston lower surface, plays the effect of blocking-up infusion channel, and therefore sealing effectiveness is better.
