Description

Technical Field

[0001] The present application relates to the technical field of coolant pots, and in particular to a sealing structure for a coolant pot. Background Art

[0002] A coolant pot is a container for holding automotive coolant. Coolant is an essential raw material during the use of an automobile. When the automotive engine is running, a large amount of heat is generated. The coolant exchanges heat with the engine and takes out the excess heat from the engine, thereby maintaining the stable operation of the engine.

[0003] Existing coolant pots generally include a pot body. The pot body is provided with a liquid inlet, and a cover body is provided on the threaded cover of the liquid inlet. When it is necessary to replenish the coolant into the pot body, the cover body can be loosened by threading at this time to open the liquid inlet. At this time, the coolant can be replenished into the pot body from the liquid inlet. And after the replenishment is completed, the cover body is tightened by threading again, so as to close the liquid inlet.

[0004] However, relying only on the threaded connection between the cover body and the liquid inlet does not meet the condition of complete sealing. Since the coolant is volatile, as the use time extends, the coolant is likely to volatilize from the connection between the cover body and the liquid inlet, thus requiring frequent replenishment of the coolant, which affects the use. Utility Model Content

[0005] In order to improve the sealing performance of the coolant pot, the present application provides a sealing structure for a coolant pot.

[0006] A sealing structure for a coolant pot provided by the present application adopts the following technical solutions:

[0007] A sealing structure for a coolant pot includes a pot body. The pot body is provided with a liquid inlet. The liquid inlet is threadedly connected with a sealing cover. A plugging member is arranged in the liquid inlet. The sealing cover is provided with a connecting component for connecting the plugging member.

[0008] By adopting the above technical solutions, when it is necessary to cover the liquid inlet, first, the plugging member is fixedly connected to the sealing cover through the connecting component, then the plugging member is aligned and inserted into the liquid inlet, and then the sealing cover is tightened by threading. At this time, the sealing cover covers the liquid inlet, and under the action of the plugging member, the sealing of the liquid inlet is strengthened, and the volatilization of the coolant from the connection between the sealing cover and the liquid inlet is reduced, thereby being beneficial to improving the sealing performance of the coolant pot.

[0009] Optionally, the connecting component includes at least two loop bands. A clamping ring is provided around the upper end of the plugging member. Clamping ears are arranged on the inner sides of at least two loop bands. The clamping ring is clamped with the clamping ears.

[0010] By adopting the above technical solution, when it is necessary to fix the plug, the snap ring on the plug is snapped into the lugs. Under the restrictive action of the lugs, the plug and the sealing cover are fixed to each other at this time, which is conducive to improving the stability of the mutual fixation between the plug and the sealing cover.

[0011] Optionally, a sealing ring is sleeved on the side wall of the plug, and the plug is provided with a limiting component for restricting the movement of the sealing ring.

[0012] By adopting the above technical solution, the sealing ring is beneficial to further strengthen the sealing between the plug and the inner wall of the liquid inlet, thereby strengthening the prevention of the volatilization of the coolant.

[0013] Optionally, the limiting component includes two limiting rings, and the two limiting rings are arranged on the side wall of the plug, and the two limiting rings enclose to form a receiving space for the sealing ring.

[0014] By adopting the above technical solution, under the action of the limiting ring, the sealing ring is less likely to shift when the plug is inserted.

[0015] Optionally, a limiting protrusion is provided at the cover opening of the sealing cover, and a retaining ear is provided on the outer wall of the liquid inlet.

[0016] By adopting the above technical solution, when the sealing cover is rotated in a threaded manner, the sealing cover drives the limiting protrusion to rotate. When the sealing cover is tightened, the limiting protrusion abuts against one side of the retaining ear to indicate the locking state of the sealing cover.

[0017] Optionally, a clamping point is further provided at the cover opening of the sealing cover, and the clamping point is provided with an arc surface.

[0018] By adopting the above technical solution, when the sealing cover is tightened, the retaining ear moves between the clamping point and the limiting protrusion at this time, thereby preventing the sealing cover from loosening, and the arc surface is beneficial to improving the stability of the retaining ear being clamped between the clamping point and the limiting protrusion.

[0019] Optionally, the snap ring is made of a metal sheet.

[0020] By adopting the above technical solution, since the metal sheet has toughness, when it is necessary to disassemble and replace the plug, the snap ring can be pried open. At this time, the lugs release the restriction on the snap ring, and the plug and the sealing cover are separated, which is conducive to improving the convenience of disassembly and assembly of the plug and the sealing cover.

[0021] Optionally, a connecting ear is provided on the side wall of the kettle body, and a reinforcing rib is provided on the inner side of the connecting ear.

[0022] By adopting the above technical solution, the reinforcing rib is used to improve the strength of the connecting ear, and the connecting ear facilitates the fixed installation of the kettle body in the vehicle.

[0023] In summary, the present application includes the following beneficial technical effects:

[0024] When it is necessary to cover the liquid inlet, first, the plug is fixedly connected to the inside of the sealing cover through the connecting component, then the plug is aligned and inserted into the liquid inlet, and then the sealing cover is screwed tightly. At this time, the sealing cover covers the liquid inlet, and under the action of the plug, the sealing of the liquid inlet is strengthened, reducing the volatilization of the coolant from the connection between the sealing cover and the liquid inlet, thereby being beneficial to improving the sealing performance of the coolant kettle.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The following will further describe the present application in detail Figures 1-5 with reference to the attached drawings.

[0032] Embodiment:

[0033] Referring to Figure 1 and Figure 2 , a sealing structure of a coolant kettle includes a kettle body 1. One side of the top surface of the kettle body 1 is fixedly provided with a liquid inlet 2, and the liquid inlet 2 is threadedly connected with a sealing cover 3. A plug 4 is inserted into the liquid inlet 2. The plug 4 is used to block the liquid inlet 2, and the plug 4 is cylindrical. The plug 4 is installed inside the sealing cover 3, and the sealing cover 3 is provided with a connecting component for connecting and fixing with the plug 4.

[0034] First, the plug 4 is fixedly connected to the sealing cover 3 through a connecting component. When the sealing cover 3 needs to be fitted into the liquid inlet 2, first align the plug 4 and insert it into the liquid inlet 2, and then thread-tighten the sealing cover 3. At this time, the plug 4 blocks the liquid inlet 2, and under the action of the plug 4, the plug 4 is closely attached to the inner wall of the liquid inlet 2, thereby improving the sealing performance of the sealing cover 3 when it is closed.

[0035] Specifically, refer to Figures 2-5 , the connecting component includes a ring 5, and the number of rings 5 is at least two segments. In this embodiment, the number of rings 5 is set to four segments, and the four segments of rings 5 are respectively distributed in a circular array along the axis of the sealing cover 3, and the four segments of rings 5 enclose an installation space for the plug 4. Card lugs 6 are respectively fixed on the inner sides of the four segments of rings 5, and a snap ring 7 is fixedly provided on the upper end of the plug 4, and the snap ring 7 is clamped in the four card lugs 6.

[0036] It should be noted that the ring 5 is made of a metal sheet, and one end of the ring 5 is welded to the sealing cover 3. Since the metal sheet has toughness, when assembling the plug 4, first bend the ring 5 outwards, and the ring 5 drives the card lug 6 to bend outwards. Then, install the ring 5 at the upper end of the plug 4 into the installation space, and then bend the ring 5 back to its original position and make the card lug 6 clamped in the snap ring 7. Under the restriction of the card lug 6, at this time, the plug 4 and the sealing cover 3 are fixed to each other.

[0037] Refer to Figure 2 and Figure 3 , to further improve the sealing performance of the plug 4 when blocking, a sealing ring 8 is also sleeved on the side wall of the plug 4, and the sealing ring 8 is in interference fit with the inner wall of the liquid inlet 2. In addition, to prevent the sealing ring 8 from shifting when the plug 4 is inserted, the plug 4 is provided with a limiting component, and the limiting component includes a limiting ring 9. The number of limiting rings 9 is set to two, and the two limiting rings 9 are respectively fixed on the side wall of the plug 4. The two limiting rings 9 enclose a receiving space 10 for the sealing ring 8, and the sealing ring 8 is installed in the receiving space 10.

[0038] When the plug 4 is inserted into the liquid inlet 2, the plug 4 drives the sealing ring 8 to be inserted into the liquid inlet 2, and at this time, the sealing ring 8 is in interference fit with the liquid inlet 2, thereby strengthening the sealing performance between the plug 4 and the liquid inlet 2.

[0039] Refer to Figure 1 and Figure 4 , to prevent the sealing cover 3 from loosening naturally after being tightened, a limiting protrusion 11 and a clamping point 12 are respectively fixed at the cover opening of the sealing cover 3. The bottom surface of the clamping point 12 is provided with an arc surface, and an ear 13 is fixedly connected to the outer wall of the liquid inlet 2.

[0040] When the sealing cover 3 is thread-tightened, under the action of the arc surface of the clamping point 12, the limiting protrusion 11 abuts against one side of the ear 13, and the ear 13 is clamped between the clamping point 12 and the limiting protrusion 11, thereby preventing natural loosening.

[0041] It should be noted that, referring to Figure 1 , the kettle body 1 includes an upper kettle 14 and a lower kettle 15. The upper kettle 14 and the lower kettle 15 are fixedly connected to each other. One side of the top of the upper kettle 14 and the side wall of the lower kettle 15 are both fixedly connected with connecting ears 16, and reinforcing ribs 17 are fixedly connected to the inner sides of the connecting ears 16. The connecting ears 16 are used to be fixed to the internal structure of the vehicle, and the reinforcing ribs 17 are used to enhance the strength of the connecting ears 16.

[0042] Working principle of a sealing structure of a coolant kettle:

[0043] When it is necessary to fix the plug 4, since the metal sheet is flexible, for this purpose, first open the ring 5, and the ring 5 drives the lug 6 to open. Then, insert one end of the plug 4 driving the snap ring 7 into it. Then, reset and pull the ring 5, and the ring 5 drives the lug 6 to snap in the direction close to the snap ring 7. At this time, the plug 4 and the sealing cover 3 are fixed to each other.

[0044] Also, when it is necessary to fit the sealing cover 3 into the liquid inlet 2, align the plug 4 and insert it into the liquid inlet 2, and then thread-tighten the sealing cover 3. Under the action of the interference fit of the sealing ring 8, the plug 4 is hermetically plugged in the liquid inlet 2, and the sealing cover 3 is fitted on the liquid inlet 2.

[0045] In summary, under the action of the interference fit of the sealing ring 8, the plug 4 seals the liquid inlet 2, and at the same time, in cooperation with the thread tightening of the sealing cover 3, it is beneficial to improve the sealing performance of the coolant kettle.

[0046] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
