Description

A kind of fuel tank dual anti-theft lock

One, technical field: the utility model relates to mechanical field, specifically refers to Automobile manufacturing fuel oil system, fuel tank safe antitheft part.

Two, background technology: at present, in all at home and abroad auto manufacturings, according to preliminary investigation, on the auto sale market, the anti-theft lock of oil tank product of all sale all is a kind of single-point one chip design now.It is in hole of fuel lid center bit, in the hole, load onto a mechanical lock master, connect a single-point one chip member in the lock core bottom of fuel lid the inside again, during use, key is inserted in the lock core of fuel lid, the twisting key, snap is rotated, drive the single-point monolithic piece, by stretching out in the fuel lid, enter the upper edge portion of reservoir port, produce the pinning effect.

But, this kind anti-theft lock of oil tank, owing to be to adopt the design of single-point monolithic, its theftproof performance is extremely low, under the prizing of extraneous slight force amount, just can make the single-point monolithic piece in the anti-theft lock of oil tank produce the serious distortion distortion, easyly just anti-theft lock of oil tank is opened, make it lose antitheft effect, make the oil plant in the fuel tank stolen, property is incurred loss.

Three, summary of the invention:

1, goal of the invention: the purpose that the utility model discloses a kind of fuel tank dual anti-theft lock is to overcome the defective of prior art, improves the safety control performance of anti-theft lock of oil tank, reduces the stolen risk factor of fuel in the fuel tank.

2, technical scheme: the utility model is implemented by the following technical programs:

A kind of fuel tank dual anti-theft lock, comprise the magnetic force lock core, fuel lid, wherein the magnetic force lock core passes the center of fuel lid, it is characterized in that: after the magnetic force lock core passes fuel lid, be connected with 3 interlock lock bodies, described 3 interlock lock bodies comprise the lock body upper cover plate, the lock body lower cover slip that links to each other with the lock body upper cover plate, the cavity internal fixation between lock body upper cover plate, lock body lower cover slip has the three-jaw double-action plate, is connected with the column type lock pin respectively on three pawls of three-jaw double-action plate; 3 interlock lock bodies are connected with a column type cylindrical shell, on the barrel of column type cylindrical shell upper end, a circular hole are arranged every 120 °, and this circular hole is corresponding with the position of column type lock pin; On the barrel of column type cylindrical shell lower end oil hole is arranged, the bottom of column type cylindrical shell is connected with capping under the cylindrical shell.

Freely stretch in the cavity that column type lock pin and three-jaw double-action plate can form between lock body upper cover plate and lock body lower cover slip.

Column type cylindrical shell bottom is a sealing state.

The column type cylindrical shell is installed in fuel tank filler port inside.

3, advantage and effect: fuel tank dual anti-theft lock described in the utility model has the following advantages:

(1) the utility model is that a kind of 3 interlock lock bodies add the antitheft tube of column type fuel tank dual anti-theft lock; this lock designs for double insurance; when oil dropping apparatus is locked; 3 interlock lock bodies in this lock body are under the twisting of the key on the magnetic force lock core; drive the three-jaw double-action plate in 3 interlock lock body cavitys; promote three column type lock pins by the three-jaw double-action plate again; enter in the lockhole on the antitheft tube of column type top from three different angles (120 °) simultaneously, finish the anti-theft column lock protective effect of fuel tank double anti-theft tube.Unlike the used single-point one chip tank cap lock of known technology, under slight external force effect, can make its INT COMP destroyed, lose due burglary insurance effect.

Because the utility model is to select for use the magnetic force lock core that theftproof performance is very strong on the market to make lockset, adopt 3 lockings simultaneously, the double insurance design of the antitheft tube of column type lock pin and column type, increased the anti-theft feature of fuel tank, be difficult to the fuel tank dual anti-theft lock be destroyed, pries open with extraneous violence, thoroughly solve the fuel oil stolen problem in the fuel tank, therefore the utlity model has reasonable in design, safe, reliable, insurance, advantage that performance is good;

(2) the utility model is that the antitheft tube of a kind of column type adds 3 interlock lock body fuel tank dual anti-theft locks, be to adopt the double insurance design, if anti-theft lock of oil tank is just in case destroyed, anti-theft lock of oil tank is when ineffective, the antitheft tube of column type that is installed in the reservoir port just works---because the cylindrical shell bottom is a closure designs, the oil stealer also can't reach fuel tank internal with the instrument of oil pumping usefulness and go oil is stolen, and has strengthened the stolen safety of fuel tank internal fuel oil.

In sum, the tank cap lock structural improvement that the splendid and tool practicality of a kind of result of use but can be provided of structure of the present utility model, feature, and can make it have practical value and progressive really.

Five, the specific embodiment:

Fig. 1 is the utility model fuel tank dual anti-theft lock scheme drawing, and 1 is the magnetic force lock core, and 2 is fuel lid, and 7 is the column type cylindrical shell, and 8 is capping under the cylinder, and 9 is 3 interlock lock bodies, and 10 is oil hole, and 11 is key; Fig. 2 is the utility model fuel tank dual anti-theft lock three-dimensional exploded view, and 3 is the lock body upper cover plate, and 4 is the three-jaw double-action plate, and 5 is the column type lock pin, and 6 is the lock body lower cover slip.

Center with fuel lid 2 gets out a hole earlier, magnetic force lock core 1 is installed in the centre hole of fuel lid 2, and 3 interlock lock bodies 9 are connected with magnetic force lock core 1 bottom of passing fuel lid 2.

As shown in Figure 3,3 interlock lock bodies 9 are made up of four parts, promptly are connected by rivet between lock body upper cover plate 3 and the lock body lower cover slip 6, and form a cavity; A three-jaw double-action plate 4 is installed in this cavity, is separately installed with column type lock pin 5 on three pawls of three-jaw double-action plate 4, and three-jaw double-action plate 4 and column type lock pin 5 can freely stretch in cavity.

3 interlock lock bodies 9 are connected with column type cylindrical shell 7, and column type cylindrical shell 7 is fixed on fuel tank filler port inside.As shown in Figure 4, on the barrel of column type cylindrical shell 7 upper ends, along 3 circular holes of circumference rectangular distribution, and 3 circular holes are corresponding with the position of column type lock pin 5.When the key on the magnetic force lock core 1 11 rotates, driving magnetic force lock core 1 in-to-in snap rotates, the three-jaw double-action plate 4 that snap drives in 3 interlock lock body 9 cavitys rotates, promoting 3 column type lock pins 5 stretches out or withdraws from three different directions, thereby snap in the circular hole on the column type cylindrical shell 7 upper end barrels or in this circular hole, withdraw, realize the first heavy anti-theft feature.Oil hole 10 is arranged on the barrel of column type cylindrical shell 7 lower ends, and when refueling, oil plant enters the fuel tank filler port from oil hole 10.Be connected with capping 8 under the cylindrical shell in column type cylindrical shell 7 bottoms, make the bottom of column type cylindrical shell 7 form sealing state, even destroy the magnetic force lock core 1, fuel lid 2 on top, 3 interlock lock bodies 9, can not in fuel tank, be drawn into oil plant, thereby realize the second heavy anti-theft feature.
