In the utility model, set up a plastics anticreep cover of dust, can strengthen Joint strenght, avoided joint to pull and cause fuel leakage, produced potential safety hazard.Can avoid better muddy water or dust etc. to enter into connecting bridge inside, avoid corroding, play a good protection, guaranteed the clean and reliability of joint simultaneously.
As optimization, described plastics anticreep cover of dust comprises upper cover body and the lower cover of involutory setting, and a side of described upper cover body and lower cover is rotatably connected by rotating shaft, and opposite side cooperation protruding by clamping and blocked hole realizes clamping and locks.
Like this, have simple in structure, but the advantage being easy for installation and removal.
In above-mentioned connection structure, a kind of structure of plastics anticreep cover of dust is disclosed, described plastics anticreep cover of dust integral body is the cylindrical sleeve body structure that can covering jacket be connected to nylon hard tube male contact and nylon hard tube famale connector connection location, plastics anticreep cover of dust one end inside face has that a circle extends internally and can clamping spacing boss limiting section on the inner round ring boss of nylon hard tube male contact, and plastics anticreep cover of dust other end inside face has that a circle extends internally and can the spacing connection-peg limiting section in connection-peg step position, nylon hard tube famale connector end of clamping.As optimization, described plastics anticreep cover of dust comprises upper cover body and the lower cover of involutory setting, and a side of described upper cover body and lower cover is rotatably connected by rotating shaft, and opposite side cooperation protruding by clamping and blocked hole realizes clamping and locks.
In sum, the utlity model has simple in structurely, it is convenient to implement, and can improve Joint strenght and the advantage in connection reliability and service life of fuel pipe connection structure.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Shown in following Fig. 4-Fig. 6, a kind of vehicle fuel pipe connecting structure, comprise that one with the nylon hard tube male contact 2 of two round ring boss 1, with a nylon hard tube famale connector 3, described nylon hard tube famale connector 3 ends have the connection-peg 4 inserting for nylon hard tube male contact that diameter is greater than other position diameter, in the peripheral surface of connection-peg 4 near opening part, there is the draw-in groove snapping in for the outer round ring boss of nylon hard tube male contact, wherein also comprise plastics anticreep cover of dust 5, described plastics anticreep cover of dust 5 integral body are cylindrical sleeve body structure and covering jacket is connected to nylon hard tube male contact and nylon hard tube famale connector connection location, plastics anticreep cover of dust 5 one end inside faces have that a circle extends internally and the spacing boss limiting section 6 on the inner round ring boss of nylon hard tube male contact of clamping, plastics anticreep cover of dust 5 other end inside faces have that a circle extends internally and the spacing connection-peg limiting section 7 in connection-peg step position, nylon hard tube famale connector end of clamping.Wherein said plastics anticreep cover of dust comprises upper cover body 51 and the lower cover 52 of involutory setting, and a side of described upper cover body 51 and lower cover 52 is rotatably connected by rotating shaft 53, and the cooperation of opposite side by clamping projection 54 and blocked hole 55 realizes clamping and lock.
Disclosed a kind of plastics anticreep cover of dust 5 in above-mentioned connection structure, described plastics anticreep cover of dust 5 integral body are the cylindrical sleeve body structure that can covering jacket be connected to nylon hard tube male contact 2 and nylon hard tube famale connector 3 connection locations, plastics anticreep cover of dust 5 one end inside faces have that a circle extends internally and can clamping spacing boss limiting section 6 on the inner round ring boss of nylon hard tube male contact, and plastics anticreep cover of dust 5 other end inside faces have that a circle extends internally and can the spacing connection-peg limiting section 7 in connection-peg step position, nylon hard tube famale connector end of clamping.Described plastics anticreep cover of dust 5 comprises upper cover body 51 and the lower cover 52 of involutory setting, and a side of described upper cover body 51 and lower cover 52 is rotatably connected by rotating shaft 53, and the cooperation of opposite side by clamping projection 54 and blocked hole 55 realizes clamping and lock.
When the utility model is installed and used: 1, first nylon hard tube male and female connector is pegged graft and assembled by technological requirement; 2, again plastics anticreep cover of dust is enclosed within to male and female connector Plug Division, at the clamping mechanism by plastics anticreep cover of dust self, the upper and lower two parts clamping of plastics anticreep cover of dust is firm.
Like this, in fuel oil system, nylon hard tube male and female connector is after assembling, install again these plastics anticreep cover of dust parts additional, the problem that can solve and avoid has: 1) if when two nylon hard tubes exist relative motion, two nylon hard tubes that rely on plastics anticreep cover of dust anticreep boss structure that male and female connector is connected are locked together firmly.Avoid joint to pull, cause fuel leakage to produce potential safety hazard.2) again because automotive fuel oil system nylon hard tube and joint are exposed to the attack sites that car chassis and engine bin are easy to be subject to muddy water conventionally.So it is intact that plastics anticreep cover of dust can well wrap up joint, avoid muddy water to corrode joint, joint, under the protection of plastics anticreep cover of dust, has guaranteed cleanliness level and the reliability of joint.
In addition, the utility model also has simple in structure, and assembly technology is simple and easy to the advantage realizing.
