Summary of the invention
The purpose of this utility model is to solve the prior art fuel lid to breathe and antitheft the two technical matters that can not have both simultaneously, provides a kind of type of respiration guard against theft oil case lid, to overcome the deficiencies in the prior art.
To achieve these goals, the utility model type of respiration guard against theft oil case lid is screwed by tank cap lock loam cake and tank cap lock lower cover and to connect and compose; Said tank cap lock loam cake, comprise inner casing and lock inner cap, the lock inner cap place inner casing below, the lock inner cap is down protruding open column shape structure, its top perimeter is circular ring structure, inner casing is provided with centre hole, be provided with lock core in its inner casing centre hole, the centre hole that lock core passes inner casing is connected with lock pin in being arranged on the lock inner cap, is provided with spring below the lock pin, and inner wall is provided with through hole, through hole is provided with the breath net, the inner casing peripheral hardware has the shell of through hole and centre hole, and the key hole end of the centre hole of shell and lock core is corresponding, which is provided with locking closure; Said tank cap lock lower cover comprises filling strainer, and the upper end of filling strainer is provided with and locks the corresponding oil filling port of inner cap, and the periphery of filling strainer is provided with fuel tank flange and bolt, and the fuel tank flange is provided with the bolt pilfer proof closure.
In order to guarantee that effectively pilfer proof closure play can not take place when fuel tank is worked, avoided play friction and noise to occur, be provided with flat thin magnet between said pilfer proof closure and the fuel tank flange, flat thin magnet is pulled together pilfer proof closure and fuel tank flange firmly.
In order to strengthen the sealing property of tank cap lock loam cake and tank cap lock lower cover, be provided with rubber pad in the annulus of said lock inner cap top periphery.
In order to strengthen the sealing property of tank cap lock lower cover and fuel tank, be provided with rubber pad below the fuel tank flange of said filling strainer periphery.
The utility model because the shell of tank cap lock loam cake has blocked pilfer proof closure, makes the bolt on the fuel tank flange be covered and can't dismantle by pilfer proof closure under the situation of not opening tank cap lock, guarantees antitheft reliable; Be provided with between the shell of tank cap lock loam cake and the inner casing and extraneous circulation passage mutually, the breathing performance is good.The utility model is simple in structure, light firmly, dependable performance, and collection call is inhaled and be antitheft in one, has solved to breathe and antitheft the two technical matters that can not have both simultaneously, can be used on the fuel tanks such as automobile, trac., farm vehicle, construction machinery and equipment.
Description of drawings
Accompanying drawing is the utility model mounting structure scheme drawing.
Among the figure 1, key 2, lock core 3, locking closure 4, shell 5, inner casing 6, breath net 7, lock inner cap 8, rubber pad 9, lock pin 10, spring 11, oil filling port 12, pilfer proof closure 13, flat thin magnet 14, fuel tank flange 15, rubber pad 16, bolt 17, filling strainer
The specific embodiment
With reference to the accompanying drawings, the utility model it screw by tank cap lock loam cake and tank cap lock lower cover and connect and compose; The tank cap lock loam cake, comprise inner casing 5 and lock inner cap 7, the lock inner cap 7 place inner casing 5 below, lock inner cap 7 is down protruding open column shape structure, its top perimeter is circular ring structure, inner casing 5 is provided with centre hole, be provided with lock core 2 in its inner casing centre hole, the centre hole that lock core 2 passes inner casing 5 is connected with lock pin 9 in being arranged on lock inner cap 7, is provided with spring 10 below the lock pin 9, and inner wall is provided with through hole, through hole is provided with breath net 6, the inner casing peripheral hardware has the shell 4 of through hole and centre hole, and the key 1 jack end of the centre hole of shell 4 and lock core 2 is corresponding, which is provided with locking closure 3; The tank cap lock lower cover comprises filling strainer 17, and the upper end of filling strainer 17 is provided with and locks inner cap 7 corresponding oil filling ports 11, and the periphery of filling strainer 17 is provided with fuel tank flange 14 and bolt 16, and fuel tank flange 14 is provided with bolt pilfer proof closure 12; Be provided with flat thin magnet 13 between pilfer proof closure 12 and the fuel tank flange 14, flat thin magnet 13 is pulled together pilfer proof closure 12 and fuel tank flange 14 firmly; Be provided with rubber pad 8 in the annulus of lock inner cap 7 top perimeter; Be provided with rubber pad 15 below the fuel tank flange 14 of filling strainer 17 peripheries.
