Abstract
The utility model relates to an engine oil return structure. The technical scheme of the utility model is that the engine oil return structure comprises a corrugated pipe and smooth pipes on two ends of the corrugated pipe, wherein the outer wall of the smooth pipe at one end is provided with an O-shaped seal ring and is hermetically connected with one end of a joint, and the one end of the joint is provided with a joint press plate; and the other end of the joint is provided with an O-shaped seal ring and is capable of being hermetically connected with an oil return base. The engine oil return structure disclosed by the utility model has the beneficial effects that the connection between an oil return pipe and the oil return base is reliable, and the oil return pipe is not easy to drop, thus being safe and reliable.
Description
Technical field
The utility model relates to and is a kind of motor oil return structure.
Background technique
At present, the most of supercharged diesel engine for the band pressurized machine of diesel engine has deaerator etc.Machine oil after machine oil behind the cooling of charge device or deaerator separate need come back to the oil sump the inside and go.Return tube with cause being connected of oil return base close important; If because of connecting the unreasonable oil leakage that causes of design; Befouling environment but also cause oil level to reduce easily not only finally causes diesel engine to lack machine oil and damages pressurized machine, piston and crankshaft bearing liner etc., and serious meeting causes whole diesel engine to scrap.
Summary of the invention
The utility model is directed against the deficiency of existing technology, and a kind of technological scheme of motor oil return structure is provided, and adopts the present technique scheme, and the connection between present technique scheme return tube and the oil return seat is reliable, and the return tube difficult drop-off is safe and reliable.
The utility model is realized through following technical measures: a kind of motor oil return structure; The light pipe that comprises bellows and bellows two ends; Wherein the light pipe outer wall of an end is equipped with the O RunddichtringO; And be tightly connected with the end that has the joint pressing plate of joint, the other end of said joint is provided with the O RunddichtringO and can be tightly connected with the oil return seat.
The concrete characteristics of the utility model also have, and the light pipe of the above-mentioned bellows the other end has loose flange.
O RunddichtringO on the above-mentioned joint is arranged in the groove on the joint outer wall.
O RunddichtringO on above-mentioned light pipe and/or the joint has two.
Above-mentioned bellows is connected and composed by one or more snippets.
The beneficial effect of the utility model is: simple in structure, easy for installation, light pipe is connected through O shape circle (5) with joint, can guarantee that sealing has the certain deformation amount again, can reduce light pipe and the suffered stress of bellows effectively, and be easy to install; Joint and oil return seat be through seal with O ring, and pressing plate fixes, and return tube is difficult like this comes off from machine oil oil return seat seat, safe and reliable.

Among the figure, 1, the O RunddichtringO, 2, joint, 3, the joint pressing plate, 4, the O RunddichtringO, 5, light pipe, 6, bellows, 7, loose flange, 8, light pipe, 9, bolt.
Embodiment
For clearly demonstrating the technical characterstic of this programme, through an embodiment, this programme is set forth below.
Shown in accompanying drawing; A kind of motor oil return structure; Comprise one section or the bellows 6 that connects and composes by multistage and the light pipe 5,8 at bellows 6 two ends; Wherein light pipe 5 outer walls of an end are equipped with O RunddichtringO 4, and are tightly connected with the end that has joint pressing plate 3 of joint 2, and the other end of said joint 2 is provided with O RunddichtringO 1 and can be tightly connected with the oil return seat.The light pipe 8 of bellows 6 the other ends has loose flange 7.O RunddichtringO 4 on the joint 2 is arranged in the groove on joint 2 outer walls.O RunddichtringO 4,1 on light pipe 5 and/or the joint 2 has two.Wherein, When light pipe 5 is connected with joint; Light pipe 5 inserted in the joint endoporus and to light pipe 5 endoporus carry out reaming, pressing plate one end is pressed in the flexible joint upper end, the other end through bolt 9 and spacers on pressurized machine or deaerator; Return tube is difficult for from machine oil oil return seat seat, coming off like this, and is safe and reliable.
The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
Claims (5)
1. motor oil return structure; The light pipe that comprises bellows and bellows two ends; It is characterized in that; Wherein the light pipe outer wall of an end is equipped with the O RunddichtringO, and is tightly connected with the end that has the joint pressing plate of joint, and the other end of said joint is provided with the O RunddichtringO and can be tightly connected with the oil return seat.
