Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0038] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0039] like Figures 1 to 6As shown in the figure, an adapter pipe fitting according to an embodiment of the present invention includes a connecting plate 10, a first pipe body 20, a second pipe body 30, and a protective member 40. The connecting plate 10 has an installation cavity extending in a first direction. One end of the first pipe body 20 is connected to one end face of the connecting plate 10 and communicates with the installation cavity. The second pipe body 30 has a connecting portion 31 extending in the first direction, which extends into the installation cavity and connects with the connecting plate 10, so that the first pipe body 20 and the second pipe body 30 are connected. The protective member 40 includes two protective bodies 41 with arc-shaped grooves 41a. The two protective bodies 41 are connected and sleeved on the second pipe body 30. The connecting portion 31 is located between the two protective bodies 41, and the outer peripheral surface of the connecting portion 31 fits against the arc-shaped grooves 41a of the protective body 41. The end face of the protective body 41 near the connecting plate 10 is connected to the end face of the connecting plate 10 away from the first pipe body 20.

[0040] It should be noted that the terms "first direction" and "second direction" in this application are defined for the convenience of describing the positional relationship between components, specifically with the first tube 20 as a reference; wherein, the first direction refers to the axial direction of the first tube 20 (specifically, refer to...). Figure 1 (in the X direction).

[0041] One end of the first pipe body 20 is connected to one end face of the connecting plate 10 and communicates with the mounting cavity of the connecting plate 10. Then, the connecting part 31 of the second pipe body 30 is inserted into the mounting cavity and connected to the connecting plate 10. At this time, the first pipe body 20 and the second pipe body 30 are connected. When it is necessary to connect the two pipes, the end of the first pipe body 20 away from the connecting plate 10 is connected to one of the pipes, and the other pipe is connected to the second pipe body 30, thereby connecting the two pipes to allow water to pass through. In addition, since the two protective bodies 41 with arc grooves 41a are connected and fitted onto the second pipe body 30, and the outer peripheral surface of the connecting part 31 is in contact with the groove wall of the arc groove 41a, a protective effect is formed on the outside of the connecting part 31, preventing external pressure from causing the connecting part 31 to fall off the connecting plate 10. In other words, when the adapter fitting of this application is in use, the second tube 30 extends into the mounting cavity through the connecting part 31 and connects with the connecting plate 10, so that the first tube 20 and the second tube 30 are connected. Then, two protective bodies 41 are used to cover the second tube 30 to achieve a wrap-around protection of the connecting part 31, which can effectively prevent external impact, vibration damage and medium corrosion, and improve durability. If damage occurs during use, the two protective bodies 41 can be removed from the second tube 30, and then the second tube 30 can be removed from the connecting plate 10 to replace the damaged parts without the need for overall replacement, which helps to reduce maintenance costs.

[0042] For example, the connection of the connecting part 31 into the mounting cavity and the connecting plate 10 is a detachable connection. Specifically, the mounting cavity wall may have an internal thread, and the outer surface of the connecting part 31 may have an external thread that matches the internal thread. In this way, the first tube 20 and the second tube 30 can be detachably connected by a threaded connection, so that the user can clean or maintain them separately later.

[0043] Because PPR material has excellent high-temperature resistance, corrosion resistance, wear resistance, and good heat-fusion bonding properties, the second pipe body 30 and the connecting part 31 in this embodiment are both made of PPR material to reduce water outlet damage during use.

[0044] like Figures 1 to 3 As shown, in one embodiment, both ends of the two protective bodies 41 extend outwards with connecting blocks 411 in their bending direction. The connecting blocks 411 have through holes 411a and slots 411b communicating with the through holes 411a. The slots 411b extend along the width direction of the connecting blocks 411. The adapter also includes a locking member 50, which includes a locking pin 51 and locking blocks 52 disposed on both sides of the locking pin 51. The locking blocks 52 are fixed to one end of the locking pin 51 and extend radially along the locking pin 51. When the locking pin 51 is sequentially inserted into the through holes 411a of the two connecting blocks 411, and the locking blocks 52 are positioned offset from the slots 411b, the two protective bodies 41 are locked together to form a single unit.

[0045] In practical applications, after connecting the connecting part 31 to the connecting plate 10, the two protective bodies 41 are respectively fitted onto the second tube 30 to cover the connecting part 31 between the two protective bodies 41. At this time, the connecting blocks 411 on the two protective strips fit together. Then, the end of the locking pin 51 with the locking block 52 is passed through the through hole 411a of the two connecting blocks 411 in sequence, and the locking pin 51 is rotated so that the locking block 52 is in a staggered position in the slot 411b, thereby locking the two protective bodies 41 together to form a whole using the locking pin 51. When it is necessary to remove the two protective bodies 41, simply rotate the locking pin 51 so that the locking block 52 on the locking pin 51 is rotated to the position aligned with the slot 411b, and then remove the locking pin 51 from the through hole 411a to unlock and remove the two protective bodies 41. The structure is simple and easy to disassemble and assemble.

[0046] Furthermore, a sealing gasket 53 is provided at the end of the locking pin 51 away from the locking block 52, and the diameter of the sealing gasket 53 is larger than the diameter of the locking pin 51. That is, after the locking pin 51 extends into the through hole 411a, the sealing gasket 53 covers the front side of the through hole 411a, preventing external impurities from entering the through hole 411a and affecting the rotation adjustment of the locking pin 51. In addition, to facilitate the user to pick up or rotate the locking pin 51, a protrusion 54 is provided on the sealing gasket 53, and the two ends of the protrusion 54 along the extension direction of the locking block 52 are arc-shaped.

[0047] In one embodiment, one of the two protective bodies 41 has two elastic limiting strips 413 on the connecting block 411. The two limiting strips 413 are respectively located around the periphery of the through hole 411a to define a limiting space. Thus, after the locking pin 51 is inserted into the through hole 411a, the sealing gasket 53 is located within the limiting space, and the outer edge of the sealing gasket 53 is in close contact with the limiting strips 413, providing good anti-slip performance. This limits the rotation of the locking pin and improves the connection strength of the two anti-slip strips.

[0048] In one embodiment, one protective body 41 has a positioning groove 41b on its end face in the bending direction, and the other protective body 41 has a positioning block 41e on its end face in the bending direction, the positioning block 41e being adapted to the positioning groove 41b. That is, when the two protective bodies 41 are connected, the cooperation between the positioning block 41e and the positioning groove 41b serves to pre-fix the two protective bodies 41, so that they can be locked later by the locking pin 51. This effectively prevents the protective bodies 41 from being misaligned or misplaced, which would prevent the locking pin 51 from accurately passing through the through hole 411a for locking.

[0049] In practical applications, two protective bodies 41 are connected and sleeved on the second pipe body 30, but the protective bodies 41 are not connected to the connecting plate 10, and their axial direction is not limited, allowing the protective bodies 41 to rotate relative to the second pipe body 30, resulting in poor sealing performance. Therefore, as follows... Figure 7As shown, in one embodiment, mounting posts 41c are distributed circumferentially on the end face of the protective body 41 near the connecting plate 10. The mounting posts 41c extend in a first direction, and mounting holes 10b, adapted to the mounting posts 41c, are distributed circumferentially on the end face of the connecting plate 10 away from the first tube 20. That is, by opening mounting holes 10b on the end face of the connecting plate 10 and providing mounting posts 41c on the end face of the protective body 41, the end face of the protective body 41 near the connecting plate 10 is connected to the end face of the connecting plate 10, thereby restricting the axial rotation of the protective body 41 and providing a better sealing effect. In addition, it should be noted that the circumferentially distributed mounting posts 41c, in conjunction with the mounting holes 10b, can form a multi-point uniform force connection, which is beneficial for distributing loads, reducing stress concentration, improving the vibration resistance of the overall structure, and also reducing assembly difficulty and facilitating quick assembly and disassembly.

[0050] In one embodiment, the end face of the connecting plate 10 facing away from the first tube 20 is recessed to form an annular groove 10a. Two protective bodies 41 are respectively provided with a first protrusion 41d and a second protrusion 41f on their end faces facing the connecting plate 10. When the two protective bodies 41 are connected, the two ends of the first protrusion 41d abut against the connection of the second protrusion 41f and are engaged in the annular groove 10a. That is, when connecting the protective body 41 to the end face of the connecting plate 10, it is only necessary to push the protective body 41 along the first direction, causing the first protrusion 41d and the second protrusion 41f to engage in the annular groove 10a, forming a closed circumferential sealing interface. This effectively prevents liquids, gases, or impurities from seeping in from the connection between the protective body 41 and the connecting plate 10. Simultaneously, the engagement of the first protrusion 41d and the second protrusion 41f in the annular groove 10a generates radial constraint, which can restrict the relative rotation between the protective bodies 41 and prevent loosening of the connection due to torque.

[0051] In one embodiment, the outer circumferential surface of the second pipe body 30 is provided with a circumferentially oriented mating groove 30a, and the groove walls of the arc-shaped grooves 41a of both protective bodies 41 are provided with mating blocks 412 that are adapted to the mating grooves 30a. Thus, when the protective body 41 is connected to the second pipe body 30, the mutual cooperation between the mating blocks 412 and the mating grooves 30a can limit the radial displacement and relative rotation between the protective body 41 and the second pipe body 30. It also provides a clear circumferential positioning reference for the installation of the protective body 41, simplifying the alignment process and ensuring installation accuracy.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
