[0002] In the field of high-pressure testing, airtightness directly affects the accuracy and safety of test results. Traditional quick-connect couplings, due to their sealing structure design or material selection, often experience leakage at the connection point between the coupling and the water nozzle under high-pressure environments, thus affecting test accuracy. Therefore, developing an airtight coupling with high sealing performance suitable for high-pressure testing environments is particularly important. Utility Model Content
[0003] The purpose of this application is to address the above problems by providing a high-pressure testing airtightness fixture for connecting a liquid-cooled plate and a high-pressure gas source, comprising:
[0004] The adapter has a first channel inside, and the first channel has a first interface and a second interface at both ends. The first interface is used to be inserted and connected to the water nozzle of the liquid cooling plate, and the second interface is used to connect to the high-pressure gas source.
[0005] A locking member is rotatably connected to the adapter. The locking member has a first working position and a second working position. When it is in the first working position, the locking member is used to lock and fix the adapter and the water tap. When it is in the second working position, the adapter can be separated from the water tap.
[0006] According to the technical solutions provided in some embodiments of this application, a limiting member is also included. The limiting member is disposed on the adapter and is used to limit the locking member so that the locking member maintains the first working position.
[0007] According to the technical solutions provided in certain embodiments of this application, the locking member includes an integrally connected main body and an extension. The main body is rotatably connected to the adapter. The free end of the extension extends from the main body toward the adapter. When in the first working position, the free end of the extension abuts against the end of the water nozzle away from the adapter, so that the adapter and the water nozzle are locked and fixed.
[0008] According to the technical solutions provided in certain embodiments of this application, the free end of the extension has a first arc-shaped end face, and the end of the water nozzle away from the adapter has a second arc-shaped end face, wherein the first arc-shaped end face and the second arc-shaped end face match each other.
[0009] According to the technical solutions provided in certain embodiments of this application, the limiting member is rotatably connected to the adapter and has a third working position and a fourth working position. When in the third working position, the limiting member extends along a first direction and its two ends abut against the locking member to limit the locking member. When in the fourth working position, the limiting member extends along a second direction, and the locking member can switch between the first working position and the second working position. The second direction is perpendicular to the first direction.
[0010] According to the technical solutions provided in certain embodiments of this application, the adapter includes a sealing connector, the sealing connector is provided with the locking member and the limiting member, the sealing connector is provided with the first interface, and an air pipe connector is threadedly connected to one end of the air pipe connector away from the first interface, and a second interface is provided at one end of the air pipe connector away from the sealing connector.
[0011] According to the technical solutions provided in certain embodiments of this application, a sealing ring is provided in the first channel on the side near the first interface.
[0012] Compared with the prior art, the beneficial effects of this application are as follows: This application provides a high-pressure testing airtightness fixture for connecting a liquid cooling plate and a high-pressure gas source. The fixture includes an adapter, which has a first channel inside. The first channel has a first interface and a second interface at both ends. The first interface is used for inserting and connecting to the water nozzle of the liquid cooling plate, and the second interface is used for connecting to the high-pressure gas source. A locking member is rotatably connected to the adapter, which has a first working position and a second working position. When it is in the first working position, the locking member is used to lock and fix the adapter and the water nozzle. When it is in the second working position, the locking member is used to lock and fix the adapter and the water nozzle. In the second working position, the adapter can be separated from the water nozzle. By opening a first interface on the adapter, the water nozzle can be connected to the adapter through the first interface, and then connected to the high-pressure air source through the first channel. At the same time, rotating the locking part can lock the water nozzle and the adapter in place, preventing the adapter from separating from the water nozzle due to high pressure. While ensuring that the adapter can be quickly inserted and installed with the water nozzle, the locking mechanism between the adapter and the water nozzle has been optimized, making the connection between the two more stable. This effectively solves the problem of the connector easily falling off under high-pressure testing environment, ensuring the accuracy and safety of the test.

The descriptions in this section are merely illustrative and explanatory, and should not be construed as limiting the scope of protection of this application. Specifically, the described embodiments are only some embodiments of this application, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this invention.
[0022] It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.
[0023] As mentioned in the background section, to address the problems existing in the prior art, this embodiment provides a high-pressure testing airtightness fixture for connecting the liquid cooling plate 5 and the high-pressure gas source, comprising:
[0024] The adapter 1 has a first channel inside, and the first channel has a first interface 101 and a second interface 102 at both ends. The first interface 101 is used to insert and connect with the water nozzle 6 of the liquid cooling plate 5, and the second interface 102 is used to connect to the high-pressure gas source.
[0025] Locking member 2 is rotatably connected to adapter 1. Locking member 2 has a first working position and a second working position. When it is in the first working position, locking member 2 is used to lock adapter 1 and water nozzle 6 in place. When it is in the second working position, adapter 1 can be separated from water nozzle 6.
[0026] The liquid cooling plate 5 is a high-efficiency heat dissipation device with internal flow channels. It mainly achieves cooling through the liquid flowing through the internal channels. Therefore, its airtightness is related to the reliability and safety of the entire cooling system. In the prior art, the airtightness of the liquid cooling plate 5 is usually tested by gas detection method. Gas at a specific pressure is injected into the liquid cooling plate 5 through the water nozzle 6, and the pressure holding inside the liquid cooling plate 5 is observed to determine whether there is a leak. In actual implementation, an adapter is usually required to connect the water nozzle 6 of the liquid cooling plate 5 to the gas pipe of the high-pressure gas source. Most of the existing adapters are plug-in self-locking structures, but the self-locking structure is not stable under high pressure and has a large risk of dislodgement.
[0027] like Figure 1-4 As shown, the first direction is the width direction of the adapter 1, that is... Figure 3 The vertical direction is the first direction, and the second direction is the length direction of adapter 1. Figure 3 The adapter 1 can be connected to the water nozzle 6 of the liquid cooling plate 5 and the air pipe of the high-pressure air source respectively, so that the liquid cooling plate 5 and the high-pressure air source are connected through the first channel inside the adapter 1. The water nozzle 6 can be inserted into the first interface 101 along the second direction. The second interface 102 has internal threads and can be threaded to the air pipe. The locking member 2 is rotatably connected to the adapter 1. Its rotation axis extends along the first direction. When the locking member 2 rotates to be on the same plane as the water nozzle 6, that is, the first working position mentioned above, the locking member 2 abuts against the end of the water nozzle 6 away from the adapter 1. Through interaction, the adapter 1 and the water nozzle 6 are locked and fixed. When the locking member 2 rotates to the plane of its own location is perpendicular to the extension direction of the water nozzle 6, that is, the second working position mentioned above, the locking member 2 is unlocked and the water nozzle 6 can be separated from the adapter 1.
[0028] By opening a first interface 101 on the adapter 1, the water nozzle 6 can be connected to the adapter 1 via the first interface 101, and then connected to the high-pressure air source through the first channel. At the same time, rotating the locking member 2 can lock the water nozzle 6 to the adapter 1, preventing the adapter 1 from separating from the water nozzle 6 due to high pressure. While ensuring that the adapter 1 can be quickly inserted into the water nozzle 6, the locking mechanism between the adapter 1 and the water nozzle 6 is optimized, making the connection between the two more stable. This effectively solves the problem of the connector easily falling off under high-pressure testing environment, ensuring the accuracy and safety of the test.
[0029] In a preferred embodiment, a limiting member 3 is also included. The limiting member 3 is disposed on the adapter 1 and is used to limit the locking member 2 so that the locking member 2 is kept in the first working position.
[0030] like Figure 1 and Figure 2 As shown, the limiting member 3 is approximately plate-shaped or block-shaped and is located on the top of the adapter 1. The limiting member 3 can limit the rotation of the locking member 2, keeping the locking member 2 in the first working position, that is, in the same plane as the water nozzle 6. At this time, the locking member 2 abuts against the end of the water nozzle 6 away from the adapter 1, locking the adapter 1 and the water nozzle 6 in place. This achieves a double locking structure, further improving the stability of the tooling and increasing the reliability of the test data. It is suitable for long-term high-pressure testing environments.
[0031] In a preferred embodiment, the adapter 1 includes a sealing connector 11, which is provided with a locking member 2 and a limiting member 3. The sealing connector 11 has a first interface 101, and an air pipe connector 12 is threadedly connected to one end of the air pipe connector 11 away from the first interface 101. The end of the air pipe connector 12 away from the sealing connector 11 has a second interface 102.
[0032] like Figure 1 and Figure 2 As shown, the sealing joint 11 has a block structure and is made of high-strength, corrosion-resistant PVC material to ensure stability and durability under high pressure. The sealing joint 11 has first blind holes at both ends along the first direction. Two first rotating shafts 7 pass through both ends of the locking member 2 and are threaded into the corresponding first blind holes, thereby rotatably connecting the locking member 2 and the sealing joint 11. A second blind hole is provided at the top of the sealing joint 11. A second rotating shaft 8 passes through the center of the limiting member 3 and is threaded into the second blind hole, thereby rotatably connecting the limiting member 3 and the sealing joint 11. The locking member 2 and the limiting member 3 can be connected via the first rotating shaft 7 and the second rotating shaft 8. The rotating shaft 8 can be installed quickly and accurately, simplifying the installation process and facilitating the disassembly and maintenance of the tooling. The sealing joint 11 has a first interface 101, and the end of the sealing joint 11 away from the first interface 101 has a threaded hole communicating with the first interface 101. The air pipe joint 12 has a second interface 102, and the end of the air pipe joint 12 away from the second interface 102 has a threaded connection part. By connecting the threaded connection part with the threaded hole, the sealing joint 11 and the air pipe joint 12 are fixed to each other, and the two are internally connected to form a first channel extending in the second direction. The first interface 101 and the second interface 102 are connected through the first channel.
[0033] In a preferred embodiment, the locking member 2 includes an integrally connected main body 21 and an extension 22. The main body 21 is rotatably connected to the adapter 1, and the free end of the extension 22 extends from the main body 21 toward the adapter 1. When in the first working position, the free end of the extension 22 abuts against the end of the water nozzle 6 away from the adapter 1, so that the adapter 1 and the water nozzle 6 are locked and fixed.
[0034] like Figure 2 As shown, the main body 21 is approximately U-shaped, with its two ends rotatably connected to the two sides of the adapter 1 along the first direction. The extension 22 is located in the middle of the main body 21, with its free end extending toward the adapter 1. When the locking member 2 rotates to be on the same plane as the water nozzle 6, i.e., the first working position mentioned above, the free end of the extension 22 abuts against the end of the water nozzle 6 away from the adapter 1, thereby locking and fixing the adapter 1 and the water nozzle 6.
[0035] In a preferred embodiment, the free end of the extension 22 has a first arc-shaped end face, and the end of the water nozzle 6 away from the adapter 1 has a second arc-shaped end face, with the first arc-shaped end face and the second arc-shaped end face matching each other.
[0036] like Figure 3 and Figure 4As shown, the connection between the water nozzle 6 and the liquid cooling plate 5 has an arc-shaped elbow with an outwardly convex arc-shaped end face. The free end of the extension 22 has an inwardly concave arc-shaped end face that matches the shape of the elbow, i.e., the first arc-shaped end face. When the locking member 2 rotates from the second working position to the first working position, the free end of the extension 22 contacts the arc-shaped elbow on the water nozzle 6. Since the contact surfaces of the two are mutually matching arc-shaped end faces, sliding contact occurs between the two end faces until the locking member 2 rotates to the first working position. By designing two matching arc-shaped end faces, the frictional resistance between the locking member 2 and the water nozzle 6 can be reduced during the rotation of the locking member 2, and the stability after locking can be further enhanced.
[0037] In a preferred embodiment, the limiting member 3 is rotatably connected to the adapter 1 and has a third working position and a fourth working position. When in the third working position, the limiting member 3 extends along the first direction and its two ends abut against the locking member 2 to limit the locking member 2. When in the fourth working position, the limiting member 3 extends along the second direction and the locking member 2 can switch between the first working position and the second working position. The second direction is perpendicular to the first direction.
[0038] like Figure 3 and Figure 4 As shown, the limiting member 3 is located at the top of the sealing joint 11, and the extension direction of its rotation axis is perpendicular to both the first and second directions. When the locking member 2 is in the first working position, the limiting member 3 rotates around its own rotation axis to extend along the first direction, i.e., the aforementioned third working position. At this point, both ends of the limiting member 3 abut against the top of both ends of the locking member 2, thereby limiting the rotation of the locking member 2. When the limiting member 3 rotates around its own rotation axis to extend along the second direction, i.e., the aforementioned fourth working position, its two ends no longer contact the locking member 2, and the locking member 2 can then rotate freely around its own rotation axis, thus switching between the first and second working positions.
[0039] In a preferred embodiment, a sealing ring 4 is provided on the side of the first channel near the first interface 101.
[0040] like Figure 1 As shown, the sealing ring 4 is located in the first channel and on the sealing joint 11. The sealing ring 4 is made of a highly elastic and wear-resistant material, which can tightly fit the sealing joint and the water nozzle 6 of the liquid cooling plate 5 when subjected to pressure, preventing gas leakage. By setting the sealing ring 4 between the sealing joint 11 and the water nozzle 6, disassembly is more convenient and maintenance costs are reduced.
[0041] Working principle: In use, insert the water nozzle 6 of the liquid cooling plate 5 into the first interface 101, and thread the air pipe of the high-pressure air source to the second interface 102. First, rotate the locking member 2 so that it is on the same plane as the water nozzle 6, and the free end of the extension 22 abuts against the end of the water nozzle 6 away from the sealing joint 11. Then, rotate the limiting member 3 so that the limiting member 3 extends along the first direction, and the two ends of the limiting member 3 abut against the top of the two ends of the locking member 2, thereby limiting the rotation of the locking member 2. At this time, a double locking structure can be realized. When disassembly is required, first rotate the limiting member 3 so that the limiting member 3 extends along the second direction, thereby releasing the limitation on the locking member 2. Then rotate the locking member 2. When the extension 22 of the locking member 2 no longer contacts the water nozzle 6, the water nozzle 6 can be disassembled and separated from the sealing joint 11.
