Abstract
The utility model provides a safety cover for oil pipe joint, comprising a cover body with inner part hollow, bottom surface an opening face. The cover body is provided with a locating and thread off prevention structure. The locating and thread off prevention structure comprises a convex ring arranged in the inner wall of the cover body and an opening pipe sleeve arranged at the outer side of the cover body; the intracavity of the opening pipe sleeve is communicated with the hollow structure and the convex ring closely contacts the outer edge of the oil pipe joint positioned in the cover body. The cover body, the convex ring and the opening pipe sleeve are integrally die casted with flame retardant and fireproof plastics, thereby being flame retardant and fireproof and preventing fuel oil from splashing and bolt immersing in the oil from loosening; the utility model has the advantages of simple structure, convenient production, easy installation and disassembling.
Description
Technical field
The utility model relates to the oil connection safty shield, relates in particular to the diesel oil of motor car engine and the gasoline line safty shield at joint area.
Background technique
At present, along with the owning amount of automobile improves constantly, high-grade highway is more and more, because the serious accident of the baked wheaten cake car that fuel oil, oil leakage cause happens occasionally; The safety problem of fuel oil, machine oil pipeline comes into one's own day by day.The joint of oil pipe is the position that oil leak easily takes place, so the protection at this position seems and is even more important.
Owing to the radiation of high temperature parts such as outlet pipe, pressurized machine, temperature is higher in the cabin in automobile engine compartment; The sealing gasket at oil connection place is a rubber product, loses seal action because of crossing heat ageing easily, thereby causes oil leak; Owing to the burst reason, motor is during near naked light, and each oil connection place is that oil product is heated easily to produce to leak and causes the more position of large-scale combustion.In addition, the oil connection place used the whelk bolt to tighten, and vibration or when colliding with other parts also exists bolt to get loose the hidden danger that causes oil leak.Like this, when oil leak takes place for joint for a certain reason, have certain pressure oil in the pipe and can be sprayed onto on the component of other high temperature and cause burning.
Summary of the invention
In order to overcome the above-mentioned defective of prior art, the purpose of this utility model is to provide a kind of can make oil connection position heat-insulating flame-retardant, can prevent the oil connection safty shield that the oil connection bolt gets loose again.
The utility model provides a kind of oil connection safty shield, comprises cover body, and described cover body is that inner hollow structure, bottom surface are opening surface, and described cover body is provided with the location disconnecting prevention structure.
Described location disconnecting prevention structure comprises the bulge loop that is arranged on the cover body inwall and is arranged on the open circles pipe box in the cover body outside, the inner chamber of described open circles pipe box is connected with described hollow structure, and the outward edge of the oil connection that described bulge loop is interior with placing described cover body closely contacts.The cross section of described bulge loop is semicircle.Described open circles pipe box and described cover body intersect vertically, and the internal diameter of described open circles pipe box is slightly less than the external diameter of oil pipe.The opening of described open circles pipe box is the inclined-plane, and the inclined-plane is " eight " font, so that described protective housing leads when snapping into oil pipe.
Because of the external diameter of the minimum aspect ratio oil connection of described semicircle bulge loop is little, therefore behind the shielding cover inlet connector, can be clamped on the oil connection, guaranteed cover body in axial installing and locating; Therefore because of the internal diameter of described open circles pipe box is littler than oil pipe external diameter, described open circles pipe box can tighten oil pipe, has guaranteed the located lateral of described cover body, and prevents that cover body from getting loose and rotate.Described cover body, bulge loop and open circles pipe box adopt the die casting of fire-retardant fireproof plastic monoblock to make, and can effectively protect oil connection, prevent near the joint the thermal radiation and the intrusion of naked light, prevent joint when leakage of oil, manage in fuel oil outwards spray; And, oil connection shielding in described oil connection safty shield, has been played the effect that prevents accidental release to the whelk bolt of crossing of oil pipe, can also beautify the oil connection position.
In sum, owing to adopt technique scheme, the utlity model has following beneficial effect:
1, prevents the thermal radiation in the joint external world and the intrusion of naked light; Prevent joint when leakage of oil, manage in fuel oil outwards spray;
2, prevent the accidental release of whelk bolt excessively of oil pipe;
3, simple in structure, easily manufactured, install easily and dismantle.

Fig. 3 is the user mode schematic representation of the utility model oil connection safty shield.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
The 1-cover body; 2-open circles pipe box; The 3-bulge loop; 4-oil connection safty shield; 5-crosses the whelk bolt; The 6-oil connection.
Embodiment
Below in conjunction with accompanying drawing embodiment is illustrated:
Fig. 1 is the plan view of the utility model oil connection safty shield, and Fig. 2 is the A-A direction sectional view of Fig. 1; Inner chamber at cover body 1 is provided with bulge loop 3, the radius of bulge loop 3 just to block oil connection 6 in installation process not spalling plastics cover body 1 be as the criterion.The periphery of cover body 1 is provided with one section open circles pipe box 2, and the opening of open circles pipe box 2 is established an inclined-plane so that lead when snapping into oil pipe.
Fig. 3 is the user mode schematic representation of oil connection safty shield 1.After the mistake whelk bolt 5 of oil pipe is tightened, oil connection safty shield 4 is slightly firmly pressed on oil connection 6, because of there is resiliently deformable in plastics, oil connection safty shield 4 swells slightly and has packed on the oil connection, and open circles pipe box 2 blocks oil pipe under the leading role on inclined-plane simultaneously.Behind oil connection safty shield 4 cover inlet connectors 6, because of the external diameter of the minimum aspect ratio oil connection 6 of semicircle bulge loop 3 is little, so energy screens oil connection 6 plays the axially locating effect of oil connection safty shield 4.Because of the internal diameter of open circles pipe box 2 is littler than oil pipe external diameter, can holds tightly oil pipe and work to prevent that protective housing is loosening.So oil connection safty shield 4 can be securely fixed on the oil connection 6.
Because cover body, semicircle bulge loop and open circles pipe box adopt the die casting of fire-retardant fireproof plastic monoblock to make, and have fire-retardant fireproof, stop that fuel oil splashes, and prevent the function that the whelk bolt gets loose; And simple in structure, easily manufactured, install easily and dismantle.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
