Specific implementation

[0023] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the range of protection of the utility model.

[0024] Reference Figures 2-4 , the utility model provides an embodiment: a leakproof automobile oil pot cover sealing structure, including oil pot main part 1, the upper end of oil pot main part 1 is provided with oil pot mouth 2, the upper end of oil pot mouth 2 is installed with outer cover 3, the upper end of outer cover 3 is fixedly connected with handle 4, the lower end inboard of outer cover 3 is fixedly connected with inner cover 5, and the outer wall of inner cover 5 is connected with the inner wall of oil pot mouth 2 through clamping component, and clamping component includes the arc slot 11 of the outer wall four ends of inner cover 5, and the clamping groove 12 is set up in the inside of the upper side of arc slot 11, and clamping component still includes the clamping rod 10 of the inner wall four ends of oil pot mouth 2 sliding connection, and the inside of clamping rod 10 is installed with first spring 13, and the other end of first spring 13 is fixedly connected in the inside of oil pot mouth 2, and the upper side of the outer wall of inner cover 5 is installed with sealing ring 9, and the outer wall of sealing ring 9 contacts with the inner wall of oil pot mouth 2, and sealing gasket 6 is installed between the inner wall of outer cover 3 and the outer wall of inner cover 5, and the lower end of sealing gasket 6 contacts with the upper end of oil pot mouth 2, and annular soft magnet 7 is installed on the outer wall upper side of oil pot mouth 2, and annular permanent magnet 8 is installed on the inner wall of outer cover 3 corresponding the position of annular soft magnet 7.

[0025] Specifically, when installing the oil can cover, the inner cover 5 is inserted into the oil can opening 2, the arc-shaped slot 11 on the outer wall of the inner cover 5 is aligned with the clamping rod 10, and when the outer cover 3 is pressed downward, the clamping rod 10 is extruded by the inner wall of the arc-shaped slot 11, overcomes the elastic force of the first spring 13, and is retracted into the inner part of the oil can opening 2. When the clamping rod 10 reaches the position of the clamping slot 12 on the upper side of the arc-shaped slot 11, it is popped out and clamped into the clamping slot 12 under the action of the first spring 13, thereby achieving the clamping and fixing of the inner cover 5 and the oil can opening 2. At the same time, the annular permanent magnet 8 on the outer cover 3 is attracted to the annular soft magnet 7 on the outer wall of the oil can opening 2, so that the outer cover 3 is tightly attached to the oil can opening 2. The sealing ring 9 provided on the outer wall of the inner cover 5 is extruded to fill the gap between the outer wall of the inner cover 5 and the inner wall of the oil can opening 2, which can effectively prevent the oil from leaking radially. The sealing gasket 6 on the inner side of the outer cover 3 fills the gap between the outer cover 3, the inner cover 5 and the upper end surface of the oil can opening 2, which can prevent the oil from leaking axially. Through multiple dimensions to enhance the sealing performance, it can effectively prevent the oil from leaking. And through the cooperation of the clamping rod 10 and the clamping slot 12, the relative displacement of the inner cover 5 and the oil can opening 2 can be limited. Through the cooperation of the annular soft magnet 7 and the annular permanent magnet 8, the fit and stability of the outer cover 3 and the oil can opening 2 can be enhanced, so that the oil can cover can still be firmly installed on the oil can opening 2 in the dynamic environment of vehicle driving, and is not easy to loosen and fall off.

[0026] Referring to Figure 1 and Figure 4 , the inner cover 5 is provided with a cavity inside, and a ventilation assembly is arranged inside the cavity. The ventilation assembly includes a perforated plate 17 which is slidably connected in the cavity of the inner cover 5. The upper end of the perforated plate 17 is fixedly connected with a fixed rod 16, and the upper end of the fixed rod 16 is fixedly connected with an air inlet valve 15. The outer wall of the air inlet valve 15 is slidably connected to the upper side of the cavity of the inner cover 5. The lower end of the perforated plate 17 is provided with a second spring 18, and the lower end of the second spring 18 is fixedly connected to the lower part of the cavity of the inner cover 5. The upper end of the outer cover 3 is provided with a ventilation hole 14 corresponding to the position of the cavity of the inner cover 5, and the lower end of the inner cover 5 is fixedly connected with a ventilation cover 19.

[0027] Specifically, when the oil in the oil can body 1 decreases, the internal pressure of the oil can body 1 decreases, and the external air pressure is greater than the internal pressure of the oil can body 1, thereby pushing the air inlet valve 15, the fixed rod 16 and the perforated plate 17 to move downward against the elastic force of the second spring 18. The external air enters the oil can through the ventilation hole 14, the cavity of the inner cover 5, the perforated plate 17 and the ventilation cover 19, and balances the pressure. When the internal pressure of the oil can body 1 increases, the gas pushes the perforated plate 17 to move upward, closes the air inlet valve 15, and prevents the oil from overflowing from the ventilation hole 14. By automatically adjusting the pressure difference between the inside and outside of the oil can, the balance of the internal and external pressure of the oil can can be ensured, the normal use of the oil can be affected by the pressure problem, and the oil can can be deformed and damaged due to abnormal pressure, thereby prolonging the service life of the oil can.

[0028] Working principle: when installing the oil can cover, first align the arc-shaped slot 11 on the inner cover 5 with the clamping rod 10 arranged on the inner side of the oil can mouth 2, then press the outer cover 3, the outer cover 3 drives the inner cover 5 to insert into the oil can mouth 2, the clamping rod 10 is extruded by the inner wall of the arc-shaped slot 11, and is retracted to the inside of the oil can mouth 2 against the elastic force of the first spring 13, when the clamping rod 10 reaches the clamping groove 12 position, it is popped out and clamped into the clamping groove 12 under the action of the first spring 13, the clamping of the inner cover 5 and the oil can mouth 2 is realized, at the same time, the annular permanent magnet 8 and the annular soft magnet 7 are attracted to each other, further making the outer cover 3 and the oil can mouth 2 closely fit, the sealing ring 9 is extruded to fill the gap between the outer wall of the inner cover 5 and the inner wall of the oil can mouth 2, the sealing gasket 6 fills the gap between the outer cover 3, the inner cover 5 and the upper end surface of the oil can mouth 2, and the oil liquid leakage is prevented through multiple sealing, after the installation of the oil can cover is completed, when the pressure in the oil can main body 1 is reduced, the outside air pressure is greater than the pressure in the oil can main body 1, the air inlet valve 15, the fixed rod 16 and the perforated plate 17 are pushed to move downward against the elastic force of the second spring 18, the outside air enters the oil can through the air vent hole 14, the cavity of the inner cover 5, the perforated plate 17 and the air vent cover 19, and the pressure is balanced; when the pressure in the oil can is increased, the gas pushes the perforated plate 17 to move upward, the air inlet valve 15 is closed, and the oil liquid is prevented from overflowing from the air vent hole 14.

[0029] Finally, it should be pointed out that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be contained in the protection scope of the utility model.
