[0032] First, refer to Figures 1 to 3 , and describe the drinking water device of the present application. Among them, Figure 1 is the exploded view of the drinking water device of the present utility model; Figure 1 ; Figure 2 is Figure 1 the partial enlarged view of the position A in Figure 3 ; Figure 1 is the partial enlarged view of the position B in

[0033] As Figures 1 to 3 shown, in order to solve the problem that the existing faucet assembly 2 affects the assembly efficiency due to not being in the preset installation position during assembly, the drinking water device of the present application includes a connecting plate 1, a faucet assembly 2, and a water inlet pipe 3; a first limiting structure is provided on the connecting plate 1; the water inlet pipe 3 is arranged on the connecting plate 1; the faucet assembly 2 is threadedly connected to the water inlet pipe 3, and a second limiting structure cooperating with the first limiting structure is provided on the faucet assembly 2; when the faucet assembly 2 rotates to the preset installation position, the first limiting structure can be in limiting cooperation with the second limiting structure to fix the faucet assembly 2 in the preset installation position.

[0034] In the present utility model, the water inlet pipe 3 is arranged on the connecting plate 1, and the faucet assembly 2 is arranged on the connecting plate 1 by being threadedly connected to the water inlet pipe 3; and by respectively providing a first limiting structure and a second limiting structure on the connecting plate 1 and the faucet assembly 2 that can be in limiting cooperation, during the process of assembling the faucet assembly 2, once the faucet assembly 2 rotates to the preset installation position, the first limiting structure can be in limiting cooperation with the second limiting structure, thereby fixing the faucet assembly 2 in the preset installation position, which not only simplifies the assembly process, improves the assembly efficiency, but also can improve the overall aesthetic degree of the drinking water device.

[0035] Further reference is made below Figures 1 to 3 to a preferred embodiment of the drinking water device of the present application. Those skilled in the art can understand that the embodiments described below are only used to illustrate the principle of the present application and are not intended to limit the protection scope of the present application. On the premise that the drinking water device at least includes a connecting plate 1, a faucet assembly 2 and a water inlet pipe 3, those skilled in the art can adjust the following setting methods so that the present application can be applied to more specific application scenarios.

[0036] Referring to Figures 1 to 3 , the drinking water device includes a connecting plate 1, a faucet assembly 2 and a water inlet pipe 3; wherein, the faucet assembly 2 and the water inlet pipe 3 are arranged in a split structure and are respectively arranged on opposite sides of the connecting plate 1. The water inlet pipe 3 is arranged on the first side of the connecting plate 1 (such as Figure 1 the right side shown in Figure 1 ), and the faucet assembly 2 is located on the second side of the connecting plate 1 (such as

[0037] the left side shown in

[0038] ), and is threadedly connected to the water inlet pipe 3, so as to arrange the faucet assembly 2 on the connecting plate 1. One end of the water inlet pipe 3 facing away from the faucet assembly 2 is communicated with a water source to supply water to the faucet assembly 2. A limiting hole 11 is provided on one side of the connecting plate 1 close to the faucet assembly 2, and a limiting rib 21 that is in limiting cooperation with the limiting hole 11 is provided on one side of the faucet assembly 2 close to the connecting plate 1.

[0039] It should be noted that the setting forms of the first limiting structure and the second limiting structure in this application are not fixed, and those skilled in the art can flexibly adjust according to actual needs, as long as the faucet assembly 2 can be fixed at the preset installation position. For example, the first limiting structure is a limiting rib, and the second limiting structure is a limiting groove, where the limiting groove is an arc-shaped groove structure opened along the rotation path of the limiting rib; another example is that the first limiting structure is a limiting hole, and the second limiting structure is a limiting rib, where the limiting hole is an arc-shaped hole structure opened along the rotation path of the limiting rib.

[0040] Continue to refer to Figures 1 to 3 , an installation hole 12 is provided on the connecting plate 1. The side of the faucet assembly 2 close to the connecting plate 1 is the water inlet end, and a water inlet 22 is provided at the water inlet end. A part of the water inlet pipe 3 passes through the installation hole 12 and is threadedly connected to the water inlet end, so that the water inlet pipe 3 is communicated with the water inlet 22. The faucet assembly 2 is rotatably installed around the water inlet pipe 3, so that the faucet assembly 2 is threadedly connected to the water inlet pipe 3, thereby setting the faucet assembly 2 on the connecting plate 1.

[0041] Of course, the connection position of the water inlet 22 and the water inlet pipe 3 in this application is not fixed, and those skilled in the art can flexibly adjust according to the actual product situation. For example, the water inlet end of the faucet assembly 2 passes through the installation hole 12 and is butted against the water inlet pipe 3, so that the water inlet pipe 3 is communicated with the water inlet 22. The faucet assembly 2 is rotatably installed around the water inlet pipe 3, so that the faucet assembly 2 is threadedly connected to the water inlet pipe 3, thereby setting the faucet assembly 2 on the connecting plate 1.

[0042] Such as Figure 1 and Figure 2 As shown, the inner diameter of the water inlet 22 is larger than the outer diameter of the water inlet pipe 3. At this time, an internal thread 23 is provided on the inner wall of the water inlet 22, and an external thread 32 is provided on the outer wall of the part of the water inlet pipe 3 that passes through. The internal thread 23 can be threadedly connected to the external thread 32, thereby threadedly connecting the water inlet 22 and the water inlet pipe 3.

[0043] Of course, the setting positions of the internal thread 23 and the external thread 32 in this application are not immutable, and those skilled in the art can flexibly adjust according to the actual product situation, as long as the water inlet 22 and the water inlet pipe 3 can be threadedly connected. For example, when the inner diameter of the water inlet pipe 3 is larger than the outer diameter of the water inlet 22, an external thread 32 can also be provided on the outer wall of the water inlet 22, and an internal thread 23 can be provided on the inner wall of the water inlet pipe 3. The internal thread 23 is threadedly connected to the external thread 32, thereby threadedly connecting the water inlet 22 and the water inlet pipe 3.

[0044] In an alternative embodiment, when the water inlet end of the faucet assembly 2 passes through the mounting hole 12 and is connected to the water inlet pipe 3, if the inner diameter of the water inlet 22 is greater than the outer diameter of the water inlet pipe 3, then an internal thread 23 is provided on the inner wall of the water inlet 22, and an external thread 32 is provided on the outer wall of the part of the water inlet pipe 3 that passes through. The internal thread 23 can be threadedly connected to the external thread 32, thereby threadedly connecting the water inlet 22 and the water inlet pipe 3. Or, if the inner diameter of the water inlet pipe 3 is greater than the outer diameter of the water inlet 22, then an external thread 32 is provided on the outer wall of the water inlet 22, and an internal thread 23 is provided on the inner wall of the water inlet pipe 3. The internal thread 23 is threadedly connected to the external thread 32, thereby threadedly connecting the water inlet 22 and the water inlet pipe 3.

[0045] Refer to Figure 2 and Figure 3 , the number of the limiting ribs 21 is 2, and the 2 limiting ribs 21 are arranged at intervals on the outer peripheral side of the water inlet 22. By arranging the limiting ribs 21 and the water inlet 22 on the same side of the faucet assembly 2, while restricting the position of the faucet assembly 2, it does not affect the communication between the water inlet 22 and the water inlet pipe 3, ensuring that water can be normally supplied to the faucet assembly 2. The number of the limiting holes 11 is 2, and the 2 limiting holes 11 are arranged at intervals on the outer peripheral side of the mounting hole 12, and the limiting holes 11 correspond to the limiting ribs 21 one by one. During the process of installing the faucet assembly 2, the limiting rib 21 can gradually be inserted into the limiting hole 11; as the faucet assembly 2 rotates, the limiting rib 21 can move along the set path of the limiting hole 11. When the side wall of the limiting rib 21 abuts against the inner wall of the limiting hole 11, the faucet assembly 2 stops rotating, and at this time, the faucet assembly 2 is in the preset installation position. On the one hand, by the abutment of the limiting rib 21 and the limiting hole 11, the change in the position of the faucet assembly 2 can be restricted, thereby fixing the faucet assembly 2 in the preset installation position; on the other hand, when the faucet assembly 2 rotates to the preset installation position, the limiting rib 21 can abut against the hole wall of the limiting hole 11. At this time, it can give feedback to the user, enabling the user to know that the faucet assembly 2 has been in the preset installation position, avoiding the problem of the threaded connection failure caused by the user continuing to rotate the faucet assembly 2.

[0046] Of course, the set number of the first limiting structure and the second limiting structure in this application is not fixed, and those skilled in the art can flexibly adjust according to the actual product situation. For example, 1 first limiting structure is provided on the connecting plate 1, and 1 second limiting structure is provided on the faucet assembly 2.

[0047] As Figure 3 shown, a relief groove 24 is provided on the end face on the side where the water inlet 22 is arranged at the water inlet end of the faucet assembly 2. The number of the relief grooves 24 is multiple, and the multiple relief grooves 24 are arranged at intervals circumferentially around the water inlet. The setting of the relief groove 24 provides sufficient avoidance space for the thermal expansion and contraction of the material, avoiding cracks in the faucet assembly 2 due to thermal expansion and contraction during manufacturing.

[0048] As Figure 1 and Figure 3 shown, a third limiting structure is provided on one side of the connecting plate 1 close to the limiting plate 31, and a fourth limiting structure is provided in the middle of the water inlet pipe 3; wherein, the third limiting structure limits the limiting protrusion 13, and the fourth limiting structure is the limiting plate 31. The limiting plate 31 extends outwardly around the water inlet pipe 3, and the shape of the limiting plate 31 is rectangular. Specifically, the number of the limiting protrusions 13 is 6, and the 6 limiting protrusions 13 are arranged at intervals on the outer peripheral side of the limiting plate 31. Among them, 4 limiting protrusions 13 are respectively arranged at the four corners of the limiting plate 31, and 2 limiting protrusions 13 are oppositely arranged on both sides of the limiting plate 31. Among them, the limiting protrusions 13 arranged at the four corners of the limiting plate 31 are right-angled, and respectively cooperate with the four corners of the limiting plate 31, and the shape of the space formed by surrounding the limiting protrusions 13 matches the shape of the limiting plate 31. The limiting plate 31 is arranged in the space formed by surrounding the limiting protrusions 13, which can limit the rotation of the limiting plate 31.

[0049] It should be noted that the shape of the limiting plate 31 in this application is polygonal and cannot be circular; the limiting protrusions 13 can surround and form a groove-shaped structure matching the shape of the limiting plate 31, so as to clamp the limiting plate 31 in the space of the groove-shaped structure formed by the limiting protrusions 13, further restricting the rotation of the limiting plate 31.

[0050] In addition, the set shape of the limiting plate 31 in this application is not fixed, and those skilled in the art can flexibly adjust it according to actual needs. For example, the limiting plate 31 can also be in the shape of a triangle, a pentagon or a trapezoid, etc. Specifically, if the shape of the limiting plate 31 is a triangle, the number of the limiting protrusions 13 can be 3, and the 3 limiting protrusions 13 are respectively arranged at the three corners of the triangle, and the shapes of the limiting protrusions 13 respectively match the three corners of the triangle to limit the rotation of the limiting plate 31.

[0051] Of course, the set form and the set number of the third limiting structure and the fourth limiting structure in this application are not fixed, and those skilled in the art can flexibly adjust them according to actual needs. For example, the third limiting structure can also be a limiting frame, and the fourth limiting structure can also be the limiting plate 31. The limiting frame surrounds the mounting hole 12, and the limiting plate 31 can be clamped in the space inside the limiting frame to limit the rotation of the limiting plate 31.

[0052] In addition, the form of arranging the water inlet pipe 3 on the connecting plate 1 in this application is not fixed, and those skilled in the art can flexibly adjust it according to actual needs. For example, the water inlet pipe 3 can also be fixedly arranged on the connecting plate 1, and the form of fixed connection includes but is not limited to bonding and welding.

[0053] Continue to refer to Figure 3A convex rib 132 is provided on the side of the limiting protrusion 13 close to the limiting plate 31, and the end surface of the convex rib 132 away from the limiting protrusion 13 abuts against the limiting plate 31, which can reduce the contact area between the limiting protrusion 13 and the limiting plate 31 and reduce the friction between the limiting protrusion 13 and the limiting plate 31, thereby reducing the resistance encountered by the limiting plate 31 during installation and facilitating installation.

[0054] like Figure 3 As shown, an anti-dropout protrusion 131 is provided on the inner wall of the two relatively arranged limiting protrusions 13, and the anti-dropout protrusion 131 extends in the direction of the mounting hole 12, and can limit the limiting plate 31 within the area surrounded by the limiting protrusion 13 and the anti-dropout protrusion 131, so as to prevent the limiting plate 31 from falling off.

[0055] Furthermore, the connecting plate 1 is provided with an avoidance groove 121, and the setting position of the avoidance groove 121 is consistent with the projection position of the anti-slip protrusion 131 on the connecting plate 1, so that the avoidance groove 121 corresponds to the anti-slip protrusion 131, and the avoidance groove 121 is connected to the mounting hole 12. Through the above arrangement, it is convenient to remove the connecting plate 1 from the production mold, which is convenient for demoulding and simplifies the production process.

[0056] Of course, the location and number of the anti-dropout protrusions 131 in the present application are not fixed, and those skilled in the art can flexibly adjust them according to actual conditions. For example, the anti-dropout protrusions 131 can also be set at the end of the limiting protrusion 13 away from the connecting plate 1. For another example, one anti-dropout protrusion 131 is set on each limiting protrusion 13.

[0057] It should be noted that the above preferred implementations are only used to illustrate the principle of the utility model and are not intended to limit the protection scope of the utility model. Without departing from the principle of the utility model, those skilled in the art may adjust the above settings so that the utility model can be applied to more specific application scenarios.

[0058] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-coordinated manner to combine new implementations to suit more specific application scenarios.

[0059] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
