Description

Technical Field

[0001] The utility model relates to the technical field of water cooling plates, in particular to a water nozzle joint and pipeline connection structure of a water cooling plate. Background Art

[0002] In recent years, China has made significant progress in the field of water-cooled plate technology. Many universities, research institutions and enterprises have increased their research and development efforts in water-cooled plate technology, promoting the rapid development of related technologies. At the same time, a number of emerging companies focusing on the research and development and production of water-cooled plate technology have emerged in China, providing the market with more diversified choices.

[0003] With the booming development of the new energy vehicle industry and increasingly fierce market competition, improving competitiveness and innovation has become a prerequisite for the sustainable development of enterprises. To cope with this fierce market competition, water-cooling plate manufacturers are adapting their processes and technologies to improve the precision of their manufacturing processes. Ensuring the sealing of water-cooling plates when assembling them with pipelines is a fundamental and crucial consideration.

[0004] When assembling the water nozzle joint of the existing water cooling plate with the pipeline, an external plug-in buckle is used for connection. Although it is easy to disassemble, repeated plugging and unplugging will cause the buckle to loosen due to deformation of the plastic parts. In addition, due to repeated disassembly and deformation, the engagement amount is reduced and the connection effect is reduced. Therefore, the sealing performance is not very good and it is easy to leak. Utility Model Content

[0005] The purpose of the utility model is to provide a water faucet joint and pipeline connection structure of a water cooling plate, which not only overcomes the disadvantage that ordinary standard connection pairs are easy to loosen under vibration conditions, but also can extend the service life. Compared with ordinary threaded connections, the threaded connection of the water faucet joint and the pipeline has better sealing effect and lower leakage risk, making the water cooling plate more core competitive and solving the problems in the existing technology.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A water faucet joint and pipeline connection structure of a water cooling plate includes a water cooling plate body. A water faucet joint is provided on the water cooling plate body. The end face of the water faucet joint is threaded. The water faucet joint is connected to the pipeline through a thread. The thread is a double-rotation, discontinuous and variable-section thread.

[0008] Preferably, the nominal diameter of the thread is 18 mm, the pitch is 1.5 mm, and the length is 12 mm.

[0009] Preferably, the same thread section of the thread is provided with a left-handed thread and a right-handed thread, the thread is matched with the left-handed thread through the left-handed thread, and the thread is matched with the right-handed thread through the right-handed thread.

[0010] Preferably, the left-handed thread and the right-handed thread have different directions of rotation.

[0011] Preferably, a 30-degree wedge-shaped slope is provided at the bottom of the thread outside.

[0012] Preferably, a tooth tip is provided on the inner side of the thread, and the tooth tip on the inner side of the thread is pressed against the wedge-shaped inclined surface at the tooth bottom on the outer side of the thread.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model adopts a threaded connection between the faucet joint and the pipeline. The tooth tip on the inner side of the thread is tightly pressed against the wedge-shaped inclined surface at the tooth bottom on the outer side of the thread, thereby generating a large locking force. At the same time, when the inner and outer threads bite each other, the tooth tip is easy to deform, so that the load is evenly distributed on the contact surface. Therefore, this thread not only overcomes the disadvantage that ordinary standard connection pairs are easy to loosen under vibration conditions, but also can extend the service life. Compared with ordinary threaded connections, when using this thread to connect the faucet joint to the pipeline, the sealing effect is better and the leakage risk is lower, making the water cooling plate more core competitive.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] In order to solve the technical problem that the existing water-cooling plate water nozzle joint and the pipe are assembled with an external plug-in buckle connection, although it is easy to disassemble, the buckle will become loose due to deformation of the plastic part after repeated insertion and removal. In addition, due to repeated disassembly and deformation, the engagement amount is reduced, the connection effect is reduced, and the sealing performance is not very good, which is prone to leakage. Please refer to Figures 1-4 , this embodiment provides the following technical solutions:

[0022] A water faucet joint and pipeline connection structure of a water cooling plate includes a water cooling plate body. A faucet joint 1 is provided on the water cooling plate body. The end face of the faucet joint 1 has a tapped thread 2. The faucet joint 1 is connected to the pipeline through the thread 2. The thread 2 is a double-rotation, non-continuous and variable-section thread.

[0023] In this embodiment, the nominal diameter of the thread 2 is 18 mm, the pitch is 1.5 mm, and the length is 12 mm.

[0024] In this embodiment, the same thread section of the thread 2 is provided with a left-handed thread 21 and a right-handed thread 22 . The thread 2 cooperates with the left-handed thread through the left-handed thread 21 , and cooperates with the right-handed thread through the right-handed thread 22 .

[0025] The left-hand thread 21 and the right-hand thread 22 have different rotation directions.

[0026] It should be noted that since the thread 2 must have good sealing and screw-on properties, the precision requirements for the thread 2 are relatively high, and the processing needs to be divided into two steps. First, the left-handed thread 21 is processed, and then the right-handed thread 22 is processed. The cost is slightly higher than that of ordinary threads. However, it improves the sealing performance of the faucet joint 1 when it is matched with the pipeline, and reduces the risk of leakage.

[0027] In this embodiment, a 30-degree wedge-shaped inclined surface 23 is provided at the tooth bottom on the outer side of the thread 2 .

[0028] In this embodiment, a tooth tip 24 is provided on the inner side of the thread 2 , and the tooth tip 24 on the inner side of the thread 2 presses against the wedge-shaped inclined surface 23 at the tooth bottom on the outer side of the thread 2 .

[0029] It should be noted that by adding a 30-degree wedge-shaped bevel 23 at the bottom of the teeth on the outside of the thread 2, when the faucet joint 1 and the pipeline are tightened to each other, the tooth tip 24 on the inner side of the thread 2 is tightly pressed against the wedge-shaped bevel 23 at the bottom of the teeth on the outside of the thread 2, thereby generating a large locking force. At the same time, when the inner and outer threads are engaged with each other, the tooth tip 24 is easy to deform, so that the load is evenly distributed on the contact surface, avoiding the phenomenon that 80% of the total load is concentrated on the thread surface of the first and second teeth when ordinary standard threads are engaged. Therefore, this thread 2 not only overcomes the disadvantage that ordinary standard connection pairs are easy to loosen under vibration conditions, but also can extend the service life. Compared with ordinary threaded connections, when using this thread 2 to connect the faucet joint 1 to the pipeline, the sealing effect is better and the risk of leakage is lower.

[0030] Therefore, a non-traditional geometric shape is adopted to connect the faucet joint 1 and the pipeline through the thread 2 to achieve higher sealing performance and reduce the risk of leakage. Among them, the use of thread 2 to connect the faucet joint 1 and the pipeline is not only more sophisticated in structure, but also adjustable, which is very helpful for dealing with looseness or excessive tightening. In addition, it has a high degree of standardization, which reduces the thermal impact and deformation risk of the connected parts. Compared with traditional ordinary threads that are single-handed, fully continuous, and have equal-section threads, the thread 2 uses double-handed, discontinuous, and variable-section threads, which have better sealing effects and lower leakage risks, making the water-cooled plate more core competitive.
