Description

Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing and testing technology, and in particular to a device for sealing automotive radiator openings. Background Technology

[0002] The car radiator is a key component of the engine cooling system. It transfers the heat generated by the engine during operation to the air through the principle of heat exchange, keeping the coolant temperature within a reasonable range (usually 80-105℃) and preventing the engine from overheating and being damaged. The radiator's inlet and outlet are located at the top and bottom of the radiator (usually rigid pipe interfaces), connecting the engine block and the main circulation pipe of the radiator.

[0003] In the process of airtightness testing of automotive radiator pipes, sealing the airtightness testing openings is a crucial step to ensure the accuracy and reliability of the airtightness test. Its core purpose is to prevent gas leakage during the test, thereby ensuring that the test results truly reflect the sealing performance of the radiator. However, the existing method of sealing automotive radiator openings often uses plugs. Traditional plugs cannot provide real-time feedback on the leakage status when sealing the openings, making it difficult to know whether a leak has occurred, and thus inconvenient to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for sealing the opening of an automotive radiator, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A car radiator opening sealing device is used to seal the opening of a pipe, wherein the inner wall of the opening end of the pipe has a threaded groove, comprising:

[0007] A plugging head, which has external threads and is threaded into the threaded groove of a pipe, is used to plug the open end of a car radiator.

[0008] The elastic air chamber is located on the side of the sealing head away from the external thread. When a leak occurs in the pipe opening during the airtightness test of the car radiator, the leaking gas is transported to the elastic air chamber through the sealing head, causing the elastic air chamber to expand.

[0009] Preferably, the end opening of the pipe has a rounded corner, and the cross-section of the rounded corner has an arc-shaped structure.

[0010] Preferably, the sealing head has a first annular groove, and a first sealing ring is installed in the first annular groove. The first sealing ring is squeezed and sealed against the rounded inner wall of the pipe end opening.

[0011] Preferably, the sealing head has multiple through holes on one side, and the multiple through holes are distributed in a circumferential array.

[0012] Preferably, the sealing head has a channel inside, and the channel is connected to multiple through holes.

[0013] Preferably, the sealing head has an annular cap on the side away from the external thread, the annular cap is arranged in an annular structure, the annular cap is connected to the channel, and the elastic air bag is fixedly installed on the annular cap.

[0014] Preferably, a second annular groove is provided on one side of the plugging head, and a second sealing ring is installed in the second annular groove. The second sealing ring is squeezed and sealed against the side of the open end of the pipe.

[0015] This application involves screwing a plug onto the open end of a pipe. When a leak occurs during the initial sealing of the pipe opening by the first sealing ring on the plug during the airtightness test of the car radiator, the leaking gas is easily transported into the channel through multiple through holes on the plug and then into the flat elastic air bag through the ring cap. By observing the expansion of the elastic air bag in real time, it indicates that a leak has occurred at the open end of the car radiator's airtightness test. The operation is simple.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] To address the issue of traditional plugs being used in the airtightness testing of automotive radiators, which, when sealing the opening, cannot provide real-time feedback on the leakage status, making it inconvenient to detect leaks and difficult to use; for example... Figure 1 As shown, this embodiment discloses an automotive radiator opening sealing device for sealing the opening of a pipe 100, including: a sealing head 200 and an elastic air bag 300.

[0027] like Figure 2 As shown, in order to install the plug head 200, a threaded groove 101 is provided on the inner wall of the open end of the pipe 100. The plug head 200 has an external thread 201 and is threadedly installed in the threaded groove 101 of the pipe 100 to plug the open end of the car radiator.

[0028] like Figure 5 As shown, in order to achieve a preliminary seal between the plug head 200 and the opening of the pipe 100, the end opening of the pipe 100 has a rounded corner 102, the cross-section of the rounded corner 102 is an arc-shaped structure, the plug head 200 is provided with a first annular groove 202, and a first sealing ring 2021 is installed in the first annular groove 202. The first sealing ring 2021 is squeezed and sealed against the inner wall of the rounded corner 102 at the end opening of the pipe 100; thus achieving a preliminary seal between the plug head 200 and the opening of the pipe 100.

[0029] Continue as Figure 5 As shown, the sealing head 200 has multiple through holes 203 on one side, which are arranged in a circumferential array. At the same time, the sealing head 200 has a channel 204 inside, which is connected to the multiple through holes 203. When the first sealing ring 2021 on the sealing head 200 leaks during the air tightness test of the car radiator, the leaked gas can be transported to the channel 204 through the multiple through holes 203 on the sealing head 200.

[0030] Continue as Figure 5As shown, in order to install the elastic air bag 300, the sealing head 200 has an annular cap 205 on the side away from the external thread 201. The annular cap 205 is arranged in an annular structure. The elastic air bag 300 is fixedly installed on the annular cap 205. The elastic air bag 300 is initially flat. The annular cap 205 is connected to the channel 204. It is convenient for leaked gas to be transported into the elastic air bag 300 through the annular cap 205. The interior of the flat elastic air bag 300 expands due to the transport of leaked gas. By observing the expansion of the elastic air bag 300 in real time, it is indicated that there is a leak at the opening end of the car radiator airtightness test. The operation is simple.

[0031] Continue as Figure 5 As shown, in order to deliver the leaked gas into the elastic gas reservoir 300, a second annular groove 206 is provided on one side of the plugging head 200, and a second sealing ring 2061 is installed in the second annular groove 206. The second sealing ring 2061 is squeezed and sealed against the side of the open end of the pipe 100; thus achieving a double sealing effect, ensuring the sealing of the cavity area between the first sealing ring 2021 and the second sealing ring 2061 on the plugging head 200 when the plugging head 200 seals the port of the pipe 100, facilitating the delivery of the leaked gas into the elastic gas reservoir 300.
