Description

Technical Field

[0001] This utility model relates to the field of sealing joint technology, specifically a packing sealing joint for a hydraulic cooling pipeline. Background Technology

[0002] Hydraulic cooling pipelines are piping systems used to transport coolant. They are widely used in electronic equipment, industrial machinery, energy storage systems, and other fields. By circulating coolant, they remove the heat generated by the equipment, achieving efficient heat dissipation. They typically consist of pressure-resistant pipes, connectors, sealing devices, and necessary control valves. They have good corrosion resistance, sealing properties, and mechanical strength, and can adapt to different cooling media and operating pressures, ensuring reliable system operation. The packing seal joint of the hydraulic cooling pipeline is a sealing device used for pipeline connections in a liquid cooling system.

[0003] In liquid cooling piping systems, the use of lock ball connection for packing seal joints is a common connection method. This connection method has been widely recognized in practical applications due to its advantages such as simple operation and quick connection. However, despite its many conveniences, the lock ball connection method also has some potential problems that cannot be ignored.

[0004] The locking ball itself has a spherical structure, which can achieve good locking and sealing functions when the internal pressure is low. However, when the internal pressure of the liquid cooling system is too high, the locking ball is prone to slippage. Once the locking ball slips out, the locking device will lose its original fixing function, resulting in a decrease in the sealing performance of the entire connection. This failure will not only affect the normal operation of the liquid cooling pipeline, but may also lead to coolant leakage, thereby threatening the stability and safety of the entire system. Therefore, a packing sealing joint for pressurized liquid cooling pipeline is proposed to address the above problems. Utility Model Content

[0026] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Please see Figure 1-6 This utility model provides a technical solution:

[0028] A packing sealing joint for a hydraulic cooling pipeline includes a female locking joint assembly 1 and a male locking joint assembly 2. A sealing connection assembly 3 is fixedly connected to the inner side of the female locking joint assembly 1. The female locking joint assembly 1 includes a female head body 11, with a insertion groove 12 and a snap-fit ​​groove 13 at the rear end. The male locking joint assembly 2 includes a male head body 21, with an end clamping block 22 fixedly connected to the front end of the male head body 21. The sealing connection assembly 3 includes a first connecting shell 31, with a second connecting shell 32 slidably connected to the inner side of the first connecting shell 31. A first annular sealing ring 33 is fixedly connected to the outer side of the second connecting shell 32. A linear spring 34 is fixedly connected to the rear end of the first connecting shell 31. A sealing connection block 35 is fixedly connected to the rear end of the second connecting shell 32. A second annular sealing ring 36 is fixedly connected to the rear end of the sealing connection block 35. A limit slot 37 is provided at the upper end of the sealing connection block 35. A guide rail plate 38 is fixedly connected to the outer side of the sealing connection block 35. The front end of the first connecting shell 31 is fixedly connected to the inner side of the female locking joint assembly 1.

[0029] As a further implementation of this solution, an upper channel 14 is provided at the upper end of the female head body 11. A spring telescopic rod 15 is fixedly connected to the top of the female head body 11, a pull block 17 is fixedly connected to the top of the spring telescopic rod 15, and an insertion block 16 is fixedly connected to the bottom of the pull block 17. The upper channel 14 passes through the upper end of the female head body 11, and the insertion block 16 slides inside the upper channel 14. The lower end of the insertion block 16 is inserted into the inner side of the limiting slot 37. Through the above arrangement, and through the structural design of the spring telescopic rod 15 and the pull block 17, the insertion block 16 can move and extend stably, effectively preventing the components from slipping due to high pressure and enhancing the connection stability.

[0030] As a further implementation of this solution, the plug slot 12 penetrates the rear end of the female connector body 11. The number of plug slots 12 is the same as the number of snap-fit ​​slots 13. The end snap-fit ​​block 22 snaps into the inner side of the snap-fit ​​slot 13. Through the above settings, the matching design of the plug slot 12 and the snap-fit ​​slot 13 enables the end snap-fit ​​block 22 to snap precisely, ensuring the sealing of the connection part and preventing coolant leakage.

[0031] As a further implementation of this solution, the inner sides of the first connecting shell 31 and the second connecting shell 32 are both hollow. The front end of the second connecting shell 32 is embedded in the inside of the first connecting shell 31. The outer side of the first annular sealing ring 33 fits against the inner side of the first connecting shell 31. With the above arrangement, the second connecting shell 32 can slide inside the first connecting shell 31, and at the same time, it can seal the first connecting shell 31 and the second connecting shell 32.

[0032] As a further implementation of this solution, a gap is provided between the sealing connecting block 35 and the first connecting shell 31, the front end of the linear spring 34 is fixedly connected to the rear end of the first connecting shell 31, and the linear spring 34 is sleeved on the outside of the second connecting shell 32. Through the above arrangement, under the action of the elastic thrust of the linear spring 34, the sealing connecting block 35 is kept moving backward, so that the limiting slot 37 is aligned with the upper channel 14, making it convenient for the insert block 16 to be inserted into the inside of the limiting slot 37.

[0033] As a further implementation of this solution, a groove is provided on the inner side of the female head body 11, and the guide rail plate 38 is slidably connected to the inner side of the groove of the female head body 11. The inner side of the sealing connection block 35 is hollow, and the inner side of the sealing connection block 35 is connected to the inner side of the second connecting shell 32. The rear end of the second annular sealing ring 36 is attached to the front end of the male head body 21. Through the above settings, the sealing connection block 35 can be prevented from twisting inside the female head body 11, ensuring that the direction of the limiting slot 37 faces the upper channel 14. At the same time, the hollow setting of the sealing connection block 35 facilitates the fluid to enter the interior of the second connecting shell 32 through the male head body 21 and the sealing connection block 35.

[0034] Workflow: During assembly between the female lock connector assembly 1 and the male lock connector assembly 2, pull block 17 is pulled upwards. Pull block 17 causes insert block 16 to move upwards, and simultaneously pull block 17 causes spring telescopic rod 15 to extend. Insert block 16 slides inside the upper channel 14. When insert block 16 is inside the upper channel 14, align end locking block 22 with the inside of insertion groove 12, so that end locking block 22 slides inside insertion groove 12. At the same time, male head body 21 slides inside female head body 11. When the front end of male head body 21 is aligned with the first... After the two annular sealing rings 36 are attached, under the action of thrust, the second annular sealing ring 36 and the sealing connecting block 35 move forward. The second annular sealing ring 36 slides inside the groove of the female head body 11. The guide rail plate 38 limits the sealing connecting block 35 from twisting inside the female head body 11. At the same time, the second connecting shell 32 slides inside the first connecting shell 31. The first annular sealing ring 33 seals the space between the second connecting shell 32 and the first connecting shell 31. The guide rail plate 38 seals the space between the two annular sealing rings 36 and the first connecting shell 31. The sealing connection block 35 seals the male connector body 21. The linear spring 34 deforms, and when the sealing connection block 35 reaches its limit, rotating the male connector body 21 causes the end-cap locking block 22 to rotate. After rotating a certain angle, releasing the male connector body 21 allows the sealing connection block 35 to move forward under the elastic thrust of the linear spring 34, simultaneously pushing the male connector body 21 forward. This causes the end-cap locking block 22 to engage inside the locking groove 13. Then, releasing the pull block 17 allows the spring extension rod 15 to release its elastic force. Under the action of contraction, the insert block 16 drives the pull block 17 to move backward. When the insert block 16 is inserted into the inside of the limiting slot 37, the limiting slot 37 will not be able to move back and forth. This limiting method can prevent the sealing connection block 35 and the male body 21 from failing due to excessive water pressure. At the same time, through the connection method between the male body 21 and the female body 11, it is prevented that the female body 11 and the male body 21 will separate due to excessive pressure, thus ensuring the effectiveness of the seal between the female body 11 and the male body 21.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
