[0037] Refer to Figure 1, on the one hand, an embodiment of the present invention provides a faucet installation structure for connecting a faucet and a tabletop. The structure includes an installation base 1, a limiting member 2, and a claw assembly 3. The overall structure is that the limiting member 2 is fixed in the installation base 1. The screw 31 in the claw assembly 3 passes through the installation base 1 and the limiting member 2 and has a certain length. In the contracted state of the claw 33, it passes through the tabletop ( Figure 1 as shown by the rectangular frame in), and after passing through, the claw 33 automatically opens under the action of gravity and catches the tabletop. In this way, the overall faucet installation structure is fixed on the tabletop, which is convenient to operate and can be completed entirely above the tabletop without working under the tabletop. Next, each component of the faucet installation structure will be specifically introduced.

[0038] Reference Figure 2 , the installation base 1 has opposite open ends 11 and installation ends 12. An installation opening 121 is provided in the middle of the installation end 12. A preset number of fixing members 122 are provided on the side of the installation end 12 facing away from the open end 11. The fixing members 122 are embedded in the tabletop; at least one limiting groove 123 is provided on the side of the installation end 12 facing the open end 11; a threaded structure 124 is provided on the outer wall of the installation base 1.

[0039] Specifically, in the embodiment of the present invention, the installation base 1 is a cylindrical structure. One end face of the cylindrical structure is the open end 11, exposing the internal space of the installation base 1. The other end face of the cylindrical structure is the installation end 12. An installation opening 121 is provided in the middle of the installation end 12 for accommodating the claw assembly 3; the aperture of the installation opening 121 is matched with the aperture of the installation hole of the tabletop and should be less than or equal to the aperture of the installation hole of the tabletop, so as to embed the fixing member 122 into the tabletop.

[0040] The fixing member 122 is an arc-shaped sheet structure. The preset number of fixing members 122 as a whole is matched with the shape of the installation hole of the tabletop and is provided on the side of the installation end 12 facing away from the open end 11. That is to say, when installing, the open end 11 faces upward above the tabletop, the fixing member 122 faces the installation hole of the tabletop, and is embedded into the installation hole of the tabletop to fix the installation base 1 to the tabletop. The number of fixing members 122 can be determined according to the actual situation. In one embodiment, the number of fixing members 122 is set to three.

[0041] On the side of the installation end 12 facing the open end 11, there is at least one limiting groove 123. That is to say, the limiting groove 123 is in the internal space of the installation base 1 and is used to place the limiting member 2. The shape of the limiting groove 123 is matched with the shape of the limiting member 2. The limiting groove 123 can be formed by welding raised ribs along the radius extension direction on the side of the installation end 12 facing the open end 11, and a certain distance is maintained between every two ribs to form the limiting groove 123; or, on the side of the installation end 12 facing the open end 11, a groove with a certain width is recessed along the radius extension direction to serve as the limiting groove 123. The limiting grooves 123 are evenly distributed on the installation end 12, and the number of the limiting grooves 123 can be determined according to the actual situation. In the embodiment of the present invention, the number of the limiting grooves 123 is set to three, and the three limiting grooves 123 are evenly distributed on the installation end 12.

[0042] The outer wall of the installation base 1 is provided with a threaded structure 124 for the subsequent installation of the faucet body 5, which will be specifically introduced later.

[0043] Reference Figure 3 , the limiting member 2 has a hollow boss 21 and at least one limiting piece 22. The hollow boss 21 is coaxially arranged with the installation opening 121; the limiting piece 22 is matched with the limiting groove 123 so that the limiting member 2 is fixed to the installation end 12.

[0044] Specifically, the limiting piece 22 is a thin sheet structure, and each limiting piece 22 corresponds to a limiting groove 123. And multiple limiting pieces 22 are fixedly spliced, which need to be determined according to the number and shape of the limiting grooves 123 in the installation base 1. For example, in the embodiment of the present invention, the number of the limiting grooves 123 is set to three, so the number of the limiting pieces 22 is also three, and the included angle between every two limiting pieces 22 is 120 degrees. The three limiting pieces 22 are respectively placed in the three limiting grooves. The hollow boss 21 is arranged above the center of the limiting piece 22 so that the hollow boss 21 is coaxially arranged with the installation opening 121. The inner diameter of the hollow boss 21 is smaller than the aperture of the installation opening 121, but the inner diameter of the hollow boss 21 is large enough to accommodate the screw 31 in the claw assembly 3, ensuring that the screw 31 can pass through the hollow boss 21 and the installation opening 121.

[0045] Reference Figure 4 , the claw assembly 3 includes a screw 31, a pin 32 and at least one claw 33. The screw 31 passes through the hollow boss 21 and the installation opening 121. The first end of the claw 33 is hinged to the screw 31 through the pin 32 to realize the contracted state of the claw 33 close to the screw 31 and the expanded state of the claw 33 away from the screw 31; after the claw assembly 3 passes through the tabletop in the contracted state, the claw 33 automatically drops to form an expanded state so that the claw 33 fits on the tabletop.

[0046] Specifically, the screw 31 has a certain length, which at least ensures that after passing through the hollow boss 21 and the mounting opening 121 and then passing through the tabletop, the claw 33 can be completely attached to the tabletop. That is to say, the length of the screw 31 should be greater than the thickness of the hollow boss 21 plus the thickness of the mounting end 12 of the mounting base 1 plus the thickness of the tabletop. And in order to adapt to tabletops of different thicknesses, some space should be reserved for the length of the screw 31.

[0047] Continue to refer to Figure 1 , in a possible implementation manner, a first nut 4 is further included. After the screw 31 passes through the hollow boss 21 and the mounting opening 121, the first nut 4 is screwed with the screw 31 above the hollow boss 21. The model of the first nut 4 is the same as that of the screw 31. For example, in the embodiment of the present invention, the screw 31 and the first nut 4 adopt an M6 long screw 31 and an M6 hexagon nut. The screw 31 can pass through the mounting opening 121 and the hollow boss 21 from below the mounting base 1 and be screwed with the first nut 4 above the hollow boss 21. The length of the screw 31 exposed below the mounting base 1 should match the thickness of the tabletop. In order to facilitate the adjustment of the length of the screw 31, the screw 31 can also be screwed with the first nut 4 after the claw assembly 3 passes through the tabletop.

[0048] The number of claws 33 can be determined according to the actual situation. In the embodiment of the present invention, the number of claws 33 is set to three. The first end of each claw 33 is hinged to the screw 31 through a pin shaft 32. The claw 33 rotates around the pin shaft 32. When the three claws 33 converge towards the screw 31, it is in a contracted state, and at this time, it can pass through the mounting hole on the tabletop; after passing through the mounting hole on the tabletop, the three claws 33 move away from the screw 31 and are in an expanded state.

[0049] Continue to refer to Figure 4 , in a possible implementation manner, the screw 31 has a mounting portion, on which a limiting structure 311 and a through hole are provided. The pin shaft 32 passes through the first end of the claw 33 and the through hole to hinge the claw 33 to the screw 31; the position of the limiting structure 311 is matched with the position of the through hole so that the included angle between the claw 33 and the screw 31 in the contracted state is greater than 90 degrees.

[0050] A preset number of mounting parts are provided at one end of the screw 31. For example, in the embodiment of the present invention, the number of the claw 33 is set to three, so the number of the mounting parts is also three. Perforations are provided at the first end of the claw 33 and the mounting part of the screw 31, so that the pin shaft 32 can pass through the perforations of the first end of the claw 33 and the mounting part to realize the hinge connection. If there is no limiting structure 311, when there is a certain distance between the first end of the claw 33 and the screw 31, in the contracted state of the claw 33, the included angle with the screw 31 may be less than 90 degrees and closer to the screw 31. Then, under the action of gravity, it is very difficult for the claw 33 to automatically drop to the unfolded state. Therefore, a limiting structure 311 is arranged at a suitable position on the mounting part, so that in the contracted state of the claw 33, the included angle with the screw 31 is greater than 90 degrees. Then, when the claw 33 passes through the mounting hole on the tabletop, under the action of gravity, the claw 33 can automatically drop to the unfolded state and fit on the tabletop. In the embodiment of the present invention, there is no fixed requirement for the position of the limiting structure 311, as long as it cooperates with the perforation of the mounting part to make the included angle between the claw 33 and the screw 31 greater than 90 degrees in the contracted state; the limiting structure 311 can be a limiting bump. In other embodiments, the limiting structure 311 can also adopt other designs, which are not limited herein.

[0051] In order to be applicable to tabletops with different thicknesses, the fixing part 122 of the mounting base 1 of the faucet mounting structure in the embodiment of the present invention can also be designed. In a possible implementation manner, referring to Figure 2 , the fixing part 122 is arranged around the circumference of the mounting opening 121, and a preset distance is left between every two fixing parts 122 to form an avoidance notch 125; so that after the claw assembly 3 passes through the tabletop, the claw 33 is located in the avoidance notch 125.

[0052] Specifically, in order to be embedded into the mounting hole of the tabletop, the fixing part 122 has a certain length, so that the mounting base 1 is fixed on the tabletop. However, if the tabletop is too thin, the length of the fixing part 122 is greater than the thickness of the tabletop. Then, when the claw 33 passes through the tabletop and is in the unfolded state, it will be stuck on the edge of the fixing part 122, that is to say, the fixing part 122 will hinder the claw 33 from fitting on the tabletop. Therefore, a preset distance is left between every two fixing parts 122 to form an avoidance notch 125, and the avoidance notch 125 can accommodate the size of the claw 33. In this way, after the claw assembly 3 passes through the tabletop, the claw 33 is located in the avoidance notch 125, and the claw 33 can still be made to fit on the tabletop, which can be applicable to an overly thin tabletop.

[0053] Continue to refer to Figure 4 , in a possible implementation manner, at least one protruding structure 331 is provided at the second end of each claw 33; the protruding structure 331 contacts the tabletop and is used to increase the adhesion of the claw 33 to the tabletop.

[0054] Specifically, during the installation of the faucet body 5 onto the faucet installation structure, it is necessary to tightly fasten the faucet to the installation base 1. However, during installation, the installation base 1 and the claw assembly 3 may rotate under the action of external forces, resulting in low installation efficiency. Therefore, it is considered to design a convex structure 331 at the second end of the claw 33. The convex structure 331 contacts the tabletop and grips the tabletop, increasing the adhesion of the claw 33 to the tabletop. In this way, the installation base 1 and the claw assembly 3 will not rotate under the action of external forces.

[0055] The number of the convex structures 331 is at least set to one. In the embodiment of the present invention, four convex structures 331 are provided at the second end of each claw 33. In a possible implementation manner, the shape of the convex structure 331 is a triangular prism, and the lateral edge of the triangular prism contacts the tabletop. The side of the triangular prism is arranged at the second end of the claw 33 by welding or other means, and one lateral edge of the triangular prism grips the tabletop, increasing the adhesion of the claw 33 to the tabletop. In other embodiments, the shape of the convex structure 331 can also be designed in other forms, such as a triangular pyramid, a cone, etc., which are not limited herein.

[0056] Furthermore, the embodiment of the present invention also considers that the faucet installation structure is adapted to tabletops with different installation apertures. For example, when the installation aperture of the tabletop is relatively large, the length of the claw 33 can be extended to fit the tabletop around the installation hole. Refer to Figure 5 , in a possible implementation manner, each claw 33 includes a first claw 332 and a second claw 333. The first end of the first claw 332 is hinged to the screw 31; the first end of the second claw 333 is hinged to the second end of the first claw 332; the second claw 333 changes the relative rotation angle with the first claw 332 to change the length of the claw 33; at least one convex structure 331 is provided at the second end of both the first claw 332 and the second claw 333.

[0057] Specifically, the way to extend the claw 33 can be to set each claw 33 as a first claw 332 and a second claw 333. The first end of the first claw 332 is hinged to the screw 31; the first end of the second claw 333 is hinged to the second end of the first claw 332. The first claw 332 can be in a two-piece form to form a certain accommodation space, and the second claw 333 can be in a one-piece form. When the installation aperture of the tabletop is relatively small, the second claw 333 rotates into the accommodation space of the first claw 332, and the first claw 332 accommodates the second claw 333. In this way, the length of the first claw 332 is the overall length of the claw 33. When the installation aperture of the tabletop is relatively large, the second claw 333 rotates to leave the accommodation space of the first claw 332 and is parallel to the first claw 332, which can extend the overall length of the claw 33. In this way, the sum of the length of the first claw 332 and the length of the second claw 333 is the overall length of the claw 33.

[0058] At least one convex structure 331 is provided at the second end of the first jaw 332 and the second end of the second jaw 333. The convex structure 331 contacts the tabletop and grips the tabletop, increasing the adhesion of the jaw 33 to the tabletop. The number of convex structures 331 is at least one. In the embodiment of the present invention, four convex structures 331 are provided at the second end of each first jaw 332, and one convex structure 331 is provided at the second end of each second jaw 333. In a possible implementation manner, the shape of the convex structure 331 is a triangular prism, and the lateral edge of the triangular prism contacts the tabletop. The side of the triangular prism is arranged at the second end of the jaw 33 by welding or other means, and one lateral edge of the triangular prism grips the tabletop, increasing the adhesion of the jaw 33 to the tabletop. In other embodiments, the shape of the convex structure 331 can also be designed in other forms, such as a triangular pyramid, a cone, etc., which are not limited herein.

[0059] In a possible implementation manner, each jaw 33 includes a first jaw 332 and a second jaw 333. The first end of the first jaw 332 is hinged to the screw 31; the main body of the second jaw 333 is slidably connected to the main body of the first jaw 332; the second jaw 333 changes the relative sliding displacement with the first jaw 332 to change the length of the jaw 33; at least one convex structure 331 is provided at the second end of the first jaw 332 and the second end of the second jaw 333.

[0060] Specifically, the first jaw 332 can be in two pieces to form a certain accommodation space, and the second jaw 333 can be in one piece. The main body of the second jaw 333 is slidably connected to the main body of the first jaw 332 through a sliding mechanism, and the second jaw 333 slides in and out of the accommodation space. When the mounting hole diameter of the tabletop is small, the second jaw 333 slides into the accommodation space of the first jaw 332, and the first jaw 332 accommodates the second jaw 333. In this way, the length of the first jaw 332 is the overall length of the jaw 33. When the mounting hole diameter of the tabletop is large, the second jaw 333 slides out of the accommodation space of the first jaw 332, extending the overall length of the jaw 33. In this way, the sum of the length of the first jaw 332 and the length of the second jaw 333 is the overall length of the jaw 33.

[0061] At least one convex structure 331 is provided at the second end of the first jaw 332 and the second end of the second jaw 333. The convex structure 331 contacts the tabletop and grips the tabletop, increasing the adhesion of the jaw 33 to the tabletop. The number of convex structures 331 is at least one. In the embodiment of the present invention, four convex structures 331 are provided at the second end of each first jaw 332, and one convex structure 331 is provided at the second end of each second jaw 333. In a possible implementation manner, the shape of the convex structure 331 is a triangular prism, and the lateral edge of the triangular prism contacts the tabletop. The side of the triangular prism is provided at the second end of the jaw 33 by welding or other means, and one lateral edge of the triangular prism grips the tabletop, increasing the adhesion of the jaw 33 to the tabletop. In other embodiments, the shape of the convex structure 331 can also be designed in other forms, such as a triangular pyramid, a cone, etc., which are not limited herein.

[0062] On the other hand, referring to Figure 6 , the embodiment of the present invention further provides a faucet assembly, including a faucet main body 5, a second nut 6, and the faucet mounting structure as described above: The faucet main body 5 includes a rocker arm 51, a straight pipe 52, and a straight pipe base 53; the rocker arm 51 is connected to the first end of the straight pipe 52, and the second end of the straight pipe 52 is threadedly engaged with the straight pipe base 53; the lower end of the straight pipe base 53 is attached to the open end 11 of the mounting base 1; the second nut 6 surrounds the mounting base 1 and the straight pipe base 53, and is threadedly engaged with the threaded structure 124 on the outer wall of the mounting base 1, so that the faucet main body 5 is fixed on the faucet mounting structure.

[0063] Specifically, the straight pipe 52 and the straight pipe base 53 are pre-threadedly engaged. In a possible implementation manner, the straight pipe base 53 has a Z-shaped structure, and there is a platform left after being threadedly engaged with the straight pipe 52. The edge of the lower end of the straight pipe base 53 is attached to the open end 11 of the mounting base 1. The second nut 6 surrounds the platform above the straight pipe base 53, the outer periphery of the straight pipe base 53, and the outer periphery of the mounting base 1, and is threadedly engaged with the threaded structure 124 on the outer wall of the mounting base 1. In this way, the faucet main body 5 is fixed on the faucet mounting structure and then fixed on the tabletop to complete the installation process of the faucet. In the embodiment of the present invention, the second nut 6 is a large-sized hexagonal nut, and its size is adapted to the circumferential dimensions of the straight pipe base 53 and the mounting base 1.

[0064] In a possible implementation, the faucet assembly further includes a touch panel 54 and a rotating mechanism 55. The touch panel 54 is installed on the rocker arm 51; the rocker arm 51 is screwed to the first end of the straight pipe 52 through the rotating mechanism 55.
