Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to a kettle cover structure. Background Art

[0002] Expansion tank, cooling electronic equipment often uses a sealed cooling system, so some measures must be taken to compensate for the thermal expansion of the fluid caused by temperature rise. Furthermore, the air in the refrigerant must be removed, and some vibration reduction measures should be provided to reduce the pressure shock in the system. These can be achieved with an expansion tank, which is also used as a storage tank for liquid refrigerant. However, after the coolant is added to the expansion tank, the existing kettle cover of the expansion box will shake during vehicle operation, which can easily cause coolant to remain inside the cover, causing the coolant to seep out from the gap in the sealing gasket. For this reason, we propose a kettle cover structure. Utility Model Content

[0003] The purpose of the utility model is to provide a kettle cover structure to solve the problems raised in the above background technology.

[0004] To achieve the above object, the utility model provides the following technical solutions: a kettle cover structure, comprising an end cover, wherein the top inner wall of the end cover is respectively provided with inner and outer clamping teeth, the inner and outer clamping teeth are respectively buckled on the top inner and outer sides of a sealing component, and the sealing component is used to cover and seal the kettle mouth;

[0005] The sealing assembly includes an external fixing frame and a push-up seat. The bottom side of the inner wall of the external fixing frame is fixedly connected with a circulation bin. A limiting ring is arranged on the top of the circulation bin. A lifting column is slidably connected to the inner side of the limiting ring. The top of the lifting column is connected to the bottom of the push-up seat. A fixed seat is arranged inside the push-up seat. The push-up seat is slidably connected to the fixed seat. Internal circulation holes are opened on the left and right sides of the circulation bin.

[0006] Wherein, the top of the ejecting seat is fixedly connected with a first spring, and the outer top of the fixed seat is fixedly connected with a second spring.

[0007] Wherein, a sealing gasket is fixedly connected to the bottom of the lifting column.

[0008] A reflux groove is provided on one side close to the top external fixing frame, and external flow holes are provided on both sides close to the bottom external fixing frame.

[0009] The inner flow holes are correspondingly communicated with the outer flow holes.

[0010] Wherein, two sealing gaskets are fixedly connected to the outer side of the external fixing frame.

[0011] Wherein, arc-shaped protrusions are evenly spaced in the circumferential direction of the end cover, and the arc-shaped protrusions gradually increase in height from one end to the other end.

[0012] The utility model has at least the following beneficial effects:

[0013] First, after adding the coolant, the pot cover is rotated as a whole to cover the pot mouth of the expansion tank. When the vehicle is running and the coolant is shaken, the coolant liquid retained on the surface of the external fixed frame flows to the inside of the external fixed frame through the notches, reflux grooves or external flow holes at the four corners of the external fixed frame to prevent coolant residue. When the expansion tank is running to circulate the coolant, the coolant impacts the push-up seat inside the external fixed frame, so that it drives the lifting column and the sealing gasket to move upward, opening the passage of the internal components of the external fixed frame, so that the coolant flows back to the inside of the circulation bin through the passage and is discharged from the internal flow holes. At the same time, a gap is left at the top of the push-up seat and the sliding part of the fixed seat, which is convenient for the liquid to be discharged to the inside of the lifting column and finally discharged from the inside of the pot cover, further reducing the residual liquid. At the same time, a first spring and a second spring are arranged on the outside of the push-up seat and the fixed seat to facilitate the reset of the push-up seat and the lifting column.

[0024] Embodiment 1

[0025] The utility model provides a technical solution: a kettle cover structure, comprising an end cover 1, wherein the top inner wall of the end cover 1 is respectively provided with an inner clamping tooth 6 and an outer clamping tooth 7, wherein the inner clamping tooth 6 and the outer clamping tooth 7 are respectively buckled on the inner and outer sides of the top of a sealing component 3, wherein the sealing component 3 is used to cover and seal the kettle mouth, and the inner clamping tooth 6 and the outer clamping tooth 7 are used to fix the sealing component 3;

[0026] The sealing component 3 includes an external fixing frame 301 and a push-up seat 303. The bottom side of the inner wall of the external fixing frame 301 is fixedly connected with a circulation chamber 305. A limiting ring 307 is arranged on the top of the circulation chamber 305. A lifting column 310 is slidably connected to the inner side of the limiting ring 307. The top of the lifting column 310 is connected to the bottom of the push-up seat 303. A fixing seat 309 is arranged inside the push-up seat 303. The push-up seat 303 is slidably connected with the fixing seat 309. Inner circulation holes 304 are provided on the left and right sides of the circulation chamber 305. The liquid retained on the surface of the external fixing frame 301 can be cooled and discharged through the slots at the four corners of the external fixing frame 301. The reflux groove 2 or the external flow hole 5 flows into the outer fixing frame 301, and is finally discharged through the external flow hole 5 to prevent the coolant from remaining. At the same time, when the expansion tank is running to make the coolant circulate, the coolant impacts the push-up seat 303 inside the outer fixing frame 301, so that it drives the lifting column 310 and the sealing gasket 308 to move upward, opening the passage of the internal components of the outer fixing frame 301, so that the coolant flows back to the circulation chamber 305 through the passage, and is discharged from the internal flow hole 304. At the same time, a gap is left at the sliding position between the top of the push-up seat 303 and the fixing seat 309, which is convenient for the liquid to be discharged into the lifting column 310 and finally discharged from the inside of the pot cover.

[0027] The top of the ejecting seat 303 is fixedly connected with a first spring 302 , and the outer top of the fixed seat 309 is fixedly connected with a second spring 306 . The first spring 302 and the second spring 306 facilitate pushing the ejecting seat 303 and the lifting column 310 to reset.

[0028] The bottom of the lifting column 310 is fixedly connected with a sealing gasket 308, which is used to cooperate with the sealing gasket 4 to prevent the coolant from leaking out and ensure the sealing of the pot cover.

[0029] Embodiment 2

[0030] A reflux groove 2 is provided on one side of the top external fixer 301 , and external flow holes 5 are provided on both sides of the bottom external fixer 301 . The reflux groove 2 and the external flow holes 5 are used to return a small amount of coolant retained on the outer surface of the external fixer 301 to the inside of the external fixer 301 for discharge.

[0031] The inner flow hole 304 is connected to the outer flow hole 5 in correspondence. The shaking and the circulation of the coolant cause the coolant remaining inside the pot cover to circulate through the passage, then discharge into the inner flow hole 304, and finally discharge into the outer flow hole 5, and then discharge from the inside of the pot cover through the outer flow hole 5.

[0032] Two sealing gaskets 4 are fixedly connected to the outer side of the external fixing frame 301 , and the sealing gaskets 4 are used to prevent the coolant from leaking out.

[0033] See also Figure 3 In Examples 1 and 2 of the present application, arc-shaped protrusions are evenly spaced in the circumferential direction of the end cover 1, and the height of the arc-shaped protrusions gradually increases from one end to the other end. When opening the entire pot lid, one end of the arc-shaped protrusion can be used as a fulcrum for unscrewing the pot lid, preventing slipping and facilitating the opening of the pot lid.
