[0025] In order to enable those skilled in the art in the technical field to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0026] As Figure 1 and Figure 2 shown, to achieve the above object, the present utility model provides a fluid-based transition connection structure, including: the first substrate 1 and the second substrate 3.

[0027] Among them, the first internal flow channel 2 is provided inside the first substrate 1. The first substrate 1 is connected to the second substrate 3 through a plurality of bolts. The second internal flow channel 4 is provided inside the second substrate 3. When the first substrate 1 and the second substrate 3 are connected, the second internal flow channel 4 is connected to the first internal flow channel 2. By directly connecting the first substrate 1 and the second substrate 3 through multiple bolts to replace the traditional transition connection pipe for two fluid delivery components, the overall occupation of the assembly space by the transition connection structure is effectively reduced, leaving sufficient assembly space for other components.

[0028] The first connecting member 5 is provided on the upper side of the first substrate 1, and the second connecting member 6 is provided on the lower side of the second substrate 3. The first connecting member 5 is connected to the second connecting member 6 in a snap-fit manner. By connecting the first connecting member 5 and the second connecting member 6 in a snap-fit manner, the connection point between the first internal flow channel 2 and the second internal flow channel 4 can be sealed, improving the pressure-bearing capacity at the connection position between the first internal flow channel 2 and the second internal flow channel 4, thereby preventing the risk of fluid leakage and improving the safety of the fluid delivery process.

[0029] In addition, by docking and connecting the first connecting member 5 and the second connecting member 6, the first substrate 1 and the second substrate 3 can be quickly positioned, reducing the installation error and shortening the assembly cycle, thereby improving the assembly efficiency. Moreover, when the first substrate 1 or the second substrate 3 is damaged, only the first substrate 1 or the second substrate 3 needs to be replaced, without the need for overall replacement, thus improving the interchangeability of the overall transition connection structure, enhancing the maintenance efficiency, and reducing the maintenance cost.

[0030] It should be noted that one of the first connecting member 5 and the second connecting member 6 is a boss, and the other of the first connecting member 5 and the second connecting member 6 is a groove. When the first connecting member 5 is the boss, the second connecting member 6 is the groove. At this time, a first through hole is provided at the axis position of the boss, and the first through hole communicates with the first internal flow channel 2. A second through hole is provided at the axis position of the groove, and the second through hole communicates with the second internal flow channel 4. After the first substrate 1 and the second substrate 3 are docked, the groove sleeves on the outer side wall of the boss, and the first internal flow channel 2 communicates with the second internal flow channel 4.

[0031] When the first connecting member 5 is the groove, the second connecting member 6 is the boss. At this time, a first through hole is provided at the axis position of the groove, and the first through hole communicates with the first internal flow channel 2. A second through hole is provided at the axis position of the boss, and the second through hole communicates with the second internal flow channel 4. After the first substrate 1 and the second substrate 3 are docked, the groove sleeves on the outer side wall of the boss, and the first internal flow channel 2 communicates with the second internal flow channel 4.

[0032] Preferably, a first fluid inlet is provided on the left side of the first substrate 1, a first fluid outlet is provided on the upper side of the first substrate 1, a second fluid inlet is provided on the lower side of the second substrate 3, and a second fluid outlet is provided on the right side of the second substrate 3. The first fluid outlet docks with the second fluid inlet. After the first substrate 1 docks with the second substrate 3, the first fluid outlet and the second fluid inlet are docked and connected to ensure that the first internal flow channel 2 and the second internal flow channel 4 communicate with each other, and there is no fluid leakage or other phenomena at the connection position of the first internal flow channel 2 and the second internal flow channel 4.

[0033] Specifically, the second internal flow channel 4 is composed of two parts: an input part and an output part. The axis of the input part coincides with the axis of the first internal flow channel 2 at the position of the second fluid inlet to ensure seamless docking of the first internal flow channel 2 and the second internal flow channel 4 and ensure the smoothness of fluid transportation. The water flows through the output part and is transported to the second fluid outlet to complete the fluid transportation.

[0034] It should be noted that the output part communicates with the input part, and the output part is designed according to actual needs to flexibly adjust the position of the second fluid outlet. That is, according to actual needs, the second fluid outlet can also be provided on the upper side, lower side, left side, front side, and rear side of the second substrate 3 to improve the practicality of the overall transition connection structure.

[0035] In one embodiment of the utility model, a first connecting tube 7 is provided on the left side of the first substrate 1, the right end of the first connecting tube 7 is threadedly connected to the first fluid inlet, the left end of the first connecting tube 7 enters the fluid and is transported into the first internal flow channel 2 through the first connecting tube 7. At the same time, a second connecting tube 8 is provided on the right side of the second substrate 3, the left end of the second connecting tube 8 is threadedly connected to the second fluid outlet, and the right end of the first connecting tube 7 discharges the fluid output from the second internal flow channel 4.

[0036] In one embodiment of the utility model, the first connecting tube 7 is connected to the fluid input tube (not shown in the figure), and a plurality of first limiting protrusions 701 are arranged in an array on the outer wall of the left end of the first connecting tube 7. After the fluid input tube is sleeved and connected to the first connecting tube 7, the fluid input tube is locked to the outer wall of the first connecting tube 7 by a first locking ring (not shown in the figure). At this time, the locking ring binds part of the fluid input tube to the first limiting groove formed between two adjacent first limiting protrusions 701, thereby strengthening the connection strength between the first connecting tube 7 and the fluid input tube.

[0037] At the same time, the second connecting tube 8 is connected to the fluid output tube (not shown in the figure), and a plurality of second limiting protrusions 801 are arranged in an array on the outer wall of the second connecting tube 8. After the fluid output tube is sleeved and connected to the second connecting tube 8, the fluid output tube is locked to the outer wall of the second connecting tube 8 by a second locking ring (not shown in the figure). At this time, the second locking ring binds part of the fluid output tube to the second limiting groove formed between two adjacent second limiting protrusions 801, thereby strengthening the connection strength between the second connecting tube 8 and the fluid output tube.

[0038] In one embodiment of the utility model, a sealing ring 9 is provided between the groove and the boss, the inner peripheral side surface of the sealing ring 9 abuts against the outer peripheral side surface of the boss, and the outer peripheral side surface of the sealing ring 9 abuts against the inner peripheral side surface of the groove. The provision of the sealing ring 9 can enhance the sealing performance of the connection between the groove and the boss, further improve the pressure bearing capacity at the connection position between the first internal flow channel 2 and the second internal flow channel 4, prevent the risk of fluid leakage, and improve the safety of the fluid delivery process.

[0039] A connection hole is provided on the upper side of the first substrate 1, and the connection hole is used to pass a fixing bolt 10. A threaded hole is provided on the lower side of the second substrate 3, and the fixing bolt 10 is threadedly connected to the threaded hole. The fixing bolt 10 passes through the connection hole and then connects to the threaded hole. By screwing the fixing bolt 10, the first substrate 1 is fixedly connected to the second substrate 3, thereby connecting the first internal flow channel 2 and the second internal flow channel 4.

[0040] It should be noted that the shapes of the first internal flow channel 2 and the second internal flow channel 4 can be designed according to actual requirements. The first internal flow channel is welded to the flow channel by friction stir welding. This processing method can meet the diversity of the orientation of the first internal flow channel 2, thereby improving the applicable range of the overall transition connection structure. Moreover, compared with the drilling method, the friction stir welding method has a lower processing cost.

[0041] As Figure 3 shown, in an embodiment of the present utility model, a flow channel sealing plate 11 is provided on the lower side of the first substrate 1. The first internal flow channel 2 is sealed by the flow channel sealing plate 11. When the first internal flow channel 2 needs to be repaired or maintained, the flow channel sealing plate 11 can be removed to repair or maintain the first substrate 1.

[0042] In addition, a stepped groove is provided on the side of the first internal flow channel 2. The stepped groove is snap-connected to the flow channel sealing plate 11 to strengthen the sealing connection strength of the flow channel sealing plate 11 to the first internal flow channel 2. At the same time, a sealing gasket 12 is provided on the top surface of the flow channel sealing plate 11. The top surface of the sealing gasket 12 abuts against the side surface of the stepped groove to further strengthen the sealing performance between the flow channel sealing plate 11 and the first internal flow channel 2.

[0043] When the present utility model is in use, the first internal flow channel 2 completed by friction stir welding is sealed by the flow channel sealing plate 11, the first substrate 1 is connected to the second substrate 3, the convex platform is docked with the groove, and the first internal flow channel 2 and the second internal flow channel 4 are further sealed by the sealing ring 9. The first connecting pipe 7 is connected to the fluid input pipe, and the second connecting pipe 8 is connected to the fluid output pipe to complete the assembly of the overall transition connection structure.

[0044] In summary, by directly connecting the first substrate 1 and the second substrate 3 with multiple bolts, there is no need to rely on a transition connection pipe, reducing the occupation of the assembly space by the overall transition connection structure, and being able to quickly position, reducing the installation error and shortening the assembly cycle, thereby improving the assembly efficiency. Compared with the traditional transition connection pipe, the pressure-bearing capacity at the connection position of the first internal flow channel 2 and the second internal flow channel 4 is stronger, and the safety during the fluid transportation process is better.

[0045] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any actual relationship or order between these entities.

[0046] In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
