Abstract
The utility model relates to a fuel oil sealing assembly structure. The fuel oil sealing assembly structure is characterized by comprising a pressing ring (1), a wire thread and a bolt (3), the pressing ring (1) is provided with a boss (2), the bottom face of the boss (2) of the pressing ring (1) is provided with a blind hole with the wire thread, and an inner thread of the wire thread is matched with the bolt (3). The fuel oil sealing assembly structure can thoroughly solve the problem of fuel oil leakage. According to the fuel oil sealing assembly structure, the bolt needs not to be installed from the interior of a fuel oil tank, so that assembly workloads are largely lowered.
Description
Technical field
The utility model relates to a kind of fuel sealing mounting structure.
Background technology
Fuel tank is connected with larger accessory structure, is generally to be outwards connected with the accessory structure in outside through fuel oil casing from fuel tank is inner by a trim ring with stud; Stud is crimped on trim ring, between trim ring and stud face of joint, is coated with sealant.Install inevitably to collide with because of fuel oil system and destroy the sealing layer on trim ring, simultaneously due to aviation kerosene strong penetration, often occur that the stud mounting hole of fuel oil on trim ring leaks into the problem outside fuel tank.Common processing method is directly to change trim ring, and increases the coating amount of sealant on bolt cap, and obviously this can not thoroughly deal with problems.
Utility model content
Technical problem to be solved in the utility model is: a kind of sealing mounting structure of oil impregnate when thoroughly stopping fuel tank and being connected with accessory structure is provided.
The technical solution of the utility model is: a kind of fuel sealing mounting structure, is characterized by: described sealing mounting structure comprises trim ring 1, steel-wire screw-socket and the bolt 3 with boss 2; Boss 2 bottom surfaces of described trim ring 1 have the blind hole with steel-wire screw-socket; The negative thread of steel-wire screw-socket coordinates with bolt 3.
The beneficial effects of the utility model are: the utility model sealing mounting structure, trim ring is designed to the blind hole of inside with steel-wire screw-socket, bolt is worn to fuel tank inside from fuel tank outside, because bolt is the blind hole on trim ring at the point of connection of fuel tank inside, blind hole has fundamentally been cut off the passage of fuel oil from trim ring upper bolt hole seepage fuel oil, can thoroughly solve fuel blow problem; This structure need not be from the inner hold-down bolt of fuel tank simultaneously, thereby greatly reduces fitting work amount.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model sealing mounting structure;
Fig. 2 is the schematic diagram of the utility model sealing mounting structure after assembling;
Wherein, 1-trim ring, 2-boss, 3-bolt, 4-accessory structure, 5-fuel tank, 6 fuel oils.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details:
Referring to Fig. 1, a kind of fuel sealing mounting structure, comprises trim ring 1, steel-wire screw-socket and bolt 3 with boss 2; Boss 2 bottom surfaces of described trim ring 1 have the blind hole with steel-wire screw-socket; The negative thread of steel-wire screw-socket coordinates with bolt 3.
Referring to Fig. 2, in the time using the utility model to connect fuel tank 5 with accessory structure 4, its assembling mode is: trim ring 1 is in fuel tank 5 inside, and accessory structure 4, outside fuel tank 5, is connected from outside through accessory structure 4, fuel tank 5 and the inner trim ring 1 with boss 2 by bolt 3.Because bolt 3 is the blind hole on trim ring 1 at the point of connection of fuel tank 5 inside, blind hole has fundamentally been cut off the passage of fuel oil 6 from trim ring 1 upper bolt hole seepage, can thoroughly solve fuel oil 6 leakage problems.
This kind of mounting structure mode is simple, easy to operate, has improved greatly fitting work efficiency on fuel oil punch-out equipment.
Claims (1)
