Look into oil mass.In addition, oil sump bottom lowest part is also equipped with purge cock by nut, it is typically all to be made on oil sump at present
Drain oil, the engagement of purge cock screw thread is then installed in drain oil the operation to be drained the oil, still, is formed with drain oil week
The oil sump enclosed installs or removes lower purge cock due to needing regularly, and its intensity can be decreased obviously, meanwhile, pressed by oil
Power act on, in long-term use, the oil sump around drain oil is easily damaged, so occur oil leakage phenomenon, it is necessary to through
Oil sump is often changed, use cost is improved, inconvenience is brought to use.
By retrieval, the patent publication us related to present patent application is not yet found.
The content of the invention
It is an object of the invention in place of overcome the deficiencies in the prior art, there is provided a kind of engine sump tank of new automobile
With nut, the nut structure is simple, reasonable in design, easy to make, and can strengthen the intensity of the oil sump around drain oil, carries
The high service life of oil sump, reduces use cost, facility is brought to use.
Technical scheme is used by the present invention realizes goal of the invention：
A kind of engine sump tank nut of new automobile, the nut include connecting portion, top nut portion, lower nut portion
And solder joint, the bottom in the vertical coaxially connected top nut portion of upper surface one of the connecting portion, the lower surface one of the connecting portion
The top in vertical coaxially connected lower nut portion, the connecting portion, top nut portion and the inside in lower nut portion are coaxially connected a system
Go out tapped through hole, the tapped through hole can engage for screw thread and install purge cock, the company of being formed with the outer surface of the top nut
Screw thread is connect, the connection screw thread can be engaged with the screw thread phase screw thread on drain oil inwall and is installed together, the top nut portion, lower spiral shell
Female portion is in hollow cylindric, and the diameter of the connecting portion is all higher than top nut portion, the diameter in lower nut portion, the top nut
Coaxial detachable installation annular seal ring on bottom outer surface；
On the upper surface of connecting portion on the outside of the top nut portion along the circumferential direction uniform interval be integrally formed with it is multiple upwards
Raised solder joint.
Moreover, the outer surface of the connecting portion, top nut portion and lower nut portion closely sets metal anti-corrosive paint layer.
The advantages of present invention obtains and good effect are：
1st, this nut structure is simple, reasonable in design, easy to make, when in use, made on oil sump inwall be formed with
The drain oil for the screw thread that the outer surface in top nut portion is meshed, then the sealing ring of matching is coaxially installed on to the bottom in top nut portion
On portion outer surface, then top nut portion is engaged with drain oil screw thread and is installed together, and sealed by sealing ring, avoided
The phenomenon of oil leak occurs in use for the nut, improves the sealing between the nut and oil sump, passes through after compression
The connecting portion is welded on the outer surface of oil sump by solder joint, and then the engagement of purge cock screw thread is installed in tapped through hole again
, the setting of the nut, because connecting portion is welded on the outer surface of oil sump, not only increase the oily bottom around drain oil
The intensity of shell, and purge cock is directly attached with the nut, reduce mistake of the purge cock in installation or removal
To the pressure pressure of oil sump in journey, the service life of oil sump is improved, meanwhile, the nut is connected by solder joint with oil sump
Setting is connect, replacing is also extremely convenient, reduces use cost, facility is brought to use.
2nd, the outer surface of the connecting portion of this nut, top nut portion and lower nut portion closely sets metal anti-corrosive paint layer,
The setting of the metal anti-corrosive paint layer, connecting portion, top nut portion and lower nut portion can be protected, it is particularly larger in ambient humidity
Environment in use, the connecting portion, top nut portion and lower nut portion can very well be protected, improve the anti-corrosion of the nut
Corrosion, water resistance and chemical resistance, extend the service life of the nut.
Brief description of the drawings
The structure that Fig. 1 is the present invention connects front view；
Fig. 2 is Fig. 1 top view
Fig. 3 is Fig. 1 upward view.
Embodiment
For present disclosure, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinate accompanying drawing detailed
It is described as follows.It should be noted that the present embodiment is descriptive, it is not limited, it is impossible to thus limit the guarantor of the present invention
Protect scope.
A kind of engine sump tank nut of new automobile, as shown in Figure 1, Figure 2 and Figure 3, the nut include connection
Portion 1, top nut portion 3, lower nut portion 7 and solder joint 2, the bottom in the vertical coaxially connected top nut portion of upper surface one of the connecting portion
