The utility model discloses a car returns oil pipe, including first connecting pipe, bellows, second connecting pipe, first connecting pipe one end links to each other with the connecting plate, the first connecting pipe other end links to each other with the bellows, second connecting pipe one end links to each other with the bellows, the second connecting pipe other end links to each other with oil return pipe joint, second even connecting pipe has met limit baffle, limit baffle links to each other with oil return pipe joint, just the last retaining groove of having seted up of limit baffle. A car returns oil pipe, its simple structure, simple to operate, joint strength is high, stability is good, has effectively reduced the vibration of oil return in returning oil pipe to reduce noise and abnormal sound.
Description
Technical field
The utility model is related to a kind of automobile oil return pipe.
Background technology
Oil return pipe is a kind of common auto parts machinery, when the oil mass that fuel pump provides is more than the optimum oil required for engine
During amount, allow oil to return in fuel tank by oil return pipe, reach the purpose reducing fuel consumption.Existing oil return pipe exists installs inconvenience,
And oil return pipe has when being connected with fuel tank or fuel injector that mounting stability is poor, sealing is low；Simultaneously because pressure is adjusted on fuel pump
The effect of section device, makes the oil pressure of oil return higher, causes loine pressure ripple amplitude to increase, oil flow accelerates, produces resonance,
Make a noise and abnormal sound.
Utility model content
The purpose of this utility model is to provide a kind of automobile oil return pipe, and its structure is simple, easy for installation, bonding strength
Height, good stability, effectively reduce vibration in oil return pipe for the oil return, thus reducing noise and abnormal sound.
In order to achieve the above object, the technical solution of the utility model is：
A kind of automobile oil return pipe, including the first connecting tube, bellows, the second connecting tube, described first connecting tube one end with
Connecting plate is connected, and the described first connecting tube other end is connected with bellows, and described second connecting tube one end is connected with bellows, institute
State the second connecting tube other end to be connected with oil returning pipe joint；It is socketed with postive stop baffle, described limiting block outside described second connecting tube
Plate is connected with oil returning pipe joint, and offers retaining groove on described postive stop baffle.
Offer sealed groove on described oil returning pipe joint lateral wall, in described sealed groove, sealing ring is installed.
Installation through-hole is offered on described connecting plate.
In described retaining groove, crash roll is installed.
The beneficial effects of the utility model are：A kind of automobile oil return pipe, its structure is simple, easy for installation, and bonding strength is high,
Good stability, effectively reduces vibration in oil return pipe for the oil return, thus reducing noise and abnormal sound.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of postive stop baffle.
Specific embodiment
Embodiment 1
A kind of automobile oil return pipe as shown in Figure 1 and Figure 2, including the first connecting tube 1, bellows 2, the second connecting tube 3, described
First connecting tube 1 one end is connected with connecting plate 4, and described first connecting tube 1 other end is connected with bellows 2, described second connection
Pipe 3 one end is connected with bellows 2, and described second connecting tube 3 other end is connected with oil returning pipe joint 5；Outside described second connecting tube 3
It is socketed with postive stop baffle 6, described postive stop baffle 6 is connected with oil returning pipe joint 5, and it is recessed to offer screens on described postive stop baffle 6
Groove 7.The setting of bellows 2 can effectively reduce vibration in oil return pipe for the oil return, thus reducing noise and abnormal sound.Limiting block
The setting of plate 6 can improve the bonding strength of oil returning pipe joint 5 and oil return apparatus, and installs quick and convenient.
Sealed groove 8 is offered on described oil returning pipe joint 5 lateral wall, in described sealed groove 8, sealing ring 9 is installed.
The setting of sealing ring 9 can effectively improve the sealing between oil returning pipe joint 5 and oil return apparatus.
Installation through-hole 10 is offered on described connecting plate 4.The installation of connecting plate 4 is easy in the setting of installation through-hole 10.
In described retaining groove 7, crash roll 11 is installed.The setting of crash roll 11 avoids oil returning pipe joint 5 or oil return apparatus
Damage because of external force collision.
A kind of automobile oil return pipe of the present embodiment, its structure is simple, easy for installation, and bonding strength is high, good stability, effectively
Reduce vibration in oil return pipe for the oil return, thus reducing noise and abnormal sound.
