DETAILED DESCRIPTION OF THE EMBODIMENTS

[0058] Referring to FIGS. 1-12, a faucet installation device comprises a faucet A, a countertop C, and a fixing device B. The countertop C comprises a through hole penetrating in an upper and lower direction (i.e., in a vertical direction). The fixing device B comprises a base 1 and a pressing block mechanism 2. The base 1 and the pressing block mechanism 2 are disposed in a first direction, and the first direction is the upper and lower direction (i.e., the vertical direction). In this embodiment, the faucet A is a kitchen faucet. In an example, the faucet A comprises a faucet body A1, a control valve A6 disposed in the faucet body A1, a handle A3 movably connected to the faucet body A1 and operatively connected to the control valve A6 to drive the control valve A6 to achieve waterway control, a water supply pipe A2 disposed on the faucet body A1, and a water outlet portion A4 disposed on an end of the water supply pipe A2.

[0059] The base 1 comprises a sleeve. The sleeve comprises an inner side wall, and the inner side wall of the sleeve protrudes to define two connecting bases 11 and 12. Positions of the two connecting bases 11 and 12 are radially and symmetrically arranged, and an outer diameter of the sleeve is larger than an inner diameter of the through hole. The two connecting bases 11 and 12 define a first connecting base 11 and a second connecting base 12, respectively. The first connecting base 11 comprises an inlet slot 111 penetrating in the first direction, and an opening of the inlet slot 111 is disposed on an outer side wall of the first connecting base 11 to enable a first locking rod 31 to be disposed in the inlet slot 111 from an outer side of the inlet slot 111 in an inner side of the sleeve. The second connecting base 12 comprises a connecting hole 121 penetrating in the upper and lower direction (i.e., in the first direction).

[0060] The pressing block mechanism 2 comprises two pressing plates 21. The two pressing plates 21 are rotatably connected together to enable the pressing block mechanism 2 to change between an unfolded state and a folded state. A rotation axis of the two pressing plates 21 is in the first direction, and outlines of the pressing block mechanism 2 in the unfolded state and the folded state are different. An area of the outline of the pressing block mechanism 2 in the unfolded state is larger than an area of the outline of the pressing block mechanism 2 in the folded state to enable the pressing block mechanism 2 in the folded state to freely pass through the through hole of the countertop C and to enable the pressing block mechanism 2 in the unfolded state not to pass through the through hole of the countertop C.

[0061] The two pressing plates 21 are respectively connected with two locking rods 31 and 32. Each of the two locking rods 31 and 32 is a screw rod and comprises a screw head 33 and a threaded portion. The two locking rods 31 and 32 define the first locking rod 31 and a second locking rod 32, respectively. The threaded portion of the first locking rod 31 is screwed to one of the two pressing plate 21, and the first locking rod 31 is configured to move relative to the base 1 between a working state (i.e., a working position) and a movable state (i.e., a movable position). The first locking rod 31, when in the working state, is connected to the first connecting base 11, and the first locking rod 31, when in the working state, is disposed in of the inlet slot 111. As required, the first locking rod 31, when in the working state, can be disposed in a whole of the inlet slot 111 or a deepest part of the inlet slot 111. Since the first locking rod 31 is configured to move relative to the base 1 between the working state and the movable state, the movement of the first locking rod 31 comprises movement along a plane perpendicular to the first direction. That is, the first locking rod 31 is configured to move relative to the base 1 in a horizontal direction. The threaded portion of the second locking rod 32 is screwed to the other one of the two pressing plates 21, and the second locking rod 32 passes through the connecting hole 121 of the second connecting base 12. That is, the second locking rod 32 always remains in a working state. With respect to the two locking rods 31 and 32, the first locking rod 31 is configured to move in the horizontal direction, so that the first locking rod 31 moves between the working state and the movable state to drive the pressing block mechanism 2 to change between the unfolded state and the folded state.

[0062] The screw heads 33 of the two locking rods 31 and 32, when in the working state, abut top surfaces of the two connecting bases 11 and 12. The threaded portions of the two locking rods 31 and 32 are screwed to the two pressing plates 21, and the two locking rods 31 and 32 rotate to drive the two pressing plates 21 to move upward. That is, a distance between the two pressing plates 21 and the base 1 can be controlled, and the two pressing plates 21 and the base 1 are configured to be clamped to the countertop C to achieve a fixed connection due to the two locking rods 31 and 32.

[0063] In this embodiment, the two pressing plates 21 comprise locking holes 211, and inner sides of the two pressing plates 21 are embedded with nuts 22. Each of the nuts 22 is aligned with a corresponding the locking hole 211. The threaded portions of the two locking rods 31 and 32 are screwed to the nuts 22. In some embodiments, side walls of the two pressing plates 21 extend inward to define mounting grooves 212 in communication with the locking holes 211, and the nuts 22 are disposed in the mounting grooves 212. The mounting grooves 212 are configured to restrict axial positioning and rotation of the nuts 22 to facilitate processing and assembly and to enhance threaded connection strength. Positions of the nuts 22 of the two pressing plates 21 are staggered in the first direction to facilitate assembly, compact the structure, and provide more space for an installation of a water pipe of the faucet A.

[0064] In this embodiment, the fixing device B further comprises a rotation shaft 23, and the two pressing plates 21 are rotatably connected together by the rotation shaft 23. In some embodiments, each of the two pressing plates 21 comprises a semicircular plate, and two arc ends of the semicircular plate define a first end and a second end, respectively. The rotation shaft 23 is connected to the first ends of the two pressing plates 21, and the two locking rods 31 and 32 are respectively connected to the second ends of the two pressing plates 21. A connection strength between the two locking rods 31 and 32 and the two pressing plates 21 is enhanced to ensure the two pressing plates 21 tightly abut a lower side of the countertop C to improve a connection strength and to facilitate the first locking rod 31 moving to drive the pressing block mechanism 2 to change between the unfolded state and the folded state. Moreover, the configuration provides more space for the installation of the water pipe of the faucet A. Further, the first end of one pressing plate 21 of the two pressing plates 21 protrudes to define a protrusion 213, and the first end of the other pressing plate 21 of the two pressing plates 21 extends inward to define a coupling groove 214. The protrusion 213 cooperates with and is disposed in the coupling groove 214. The rotation shaft 23 passes through the first end of the other pressing plate 21 and the protrusion 213 to enhance the connection strength between the two pressing plates 21, compact the structure, and provide more space for the installation of the water pipe of the faucet A. As needed, one end of the rotation shaft 23 is fixed with a plug, and the other end of the rotation shaft 23 cooperates with a buckle 231 to enable the rotation shaft 23 to be rotatably connected to the two pressing plates 21. In some embodiments, surfaces of the semicircular plates of the two pressing plates 21 facing each other extend inward to define given spaces 24 to provide a larger space for the installation of the water pipe of the faucet A.

[0065] In this embodiment, each of the two pressing plate 21 comprises a pressing block 215 and an anti-skid pad 216 fixedly disposed on the pressing block 215. End surfaces of the two anti-skid pads 216 are aligned to ensure that the two pressing plates 21 tightly abut the countertop C, so that a friction coefficient between the two anti-skid pads 216 and the countertop C is increased, a friction force is increased, and a connection strength is increased. In some embodiments, top surfaces of the pressing blocks 215 extend inward to define slots, and lower ends of the two anti-skid pads 216 are disposed with posts 217. The posts 217 couple with and are disposed in the slots. The anti-skid pads 216 surround outer sides the two locking rods 31 and 32.

[0066] The base 1 is fixedly assembled to the faucet A. For example, a bottom portion of the faucet A cooperates with and is disposed in the base 1. A screw A5 is configured to enable the base 1 to be fixedly assembled to the faucet A. The faucet A is fixedly disposed on the countertop C through the fixing device B.

[0067] An assembly method of the faucet installation device is as follows. Step 1, referring to FIG. 3, the pressing block mechanism 2 is in the folded state, and the pressing block mechanism 2 passes through the through hole of the countertop C in a downward direction. Step 2, referring to FIG. 4, the second locking rod 32 moves to enable the second locking rod 32 and the first locking rod 31 to be unfolded, and the first locking rod 31 moves to drive the two pressing plates 21 of the pressing block mechanism 2 to be unfolded. The first locking rod 31, when in the working state, is disposed in the inlet slot 111, the two pressing plates 21 of the pressing block mechanism 2 are in the unfolded state. Step 3, referring to FIG. 5, the first locking rod 31 is tightened. Step 4, referring to FIG. 6, the second locking rod 32 is tightened. Step 5, referring to FIG. 7, water pipes A7 pass through the faucet installation device, and the water pipes A7 are in communication with the control valve A6. Step 6, referring to FIG. 8, the faucet a surrounds an outer side of the base 1. Step 7, referring to FIG. 9, the base 1 is locked to the faucet A through the screw A5. Compared with traditional installations, the faucet installation device of the present disclosure can be installed on the countertop C directly, and the user need not lie on the ground for installation. The simple installation method gives a better user experience. Further, stress points of the two pressing plates 21 of the pressing block mechanism 2 comprise the second ends of the two pressing plates 21 respectively connected to the two locking rods 31 and 32 and the first ends of the two pressing plates 21 connected to the rotation shaft 23. That is, the stress points of the pressing block mechanism 2 comprise the three positions, the three positions define a triangular structure, so the fixing device B can endure greater rotation torque and push-pull torque to ensure installation stability. Moreover, a three-point surface is the most reliable. In this embodiment, F (left and right rotation torque)4.5 N.M (Newton-meter); F (forward and backward push-pull torque)16.5 N.M. Still further, in this embodiment, the faucet installation device has a larger scope of application. With respect to kitchen faucets, three hoses with joints (i.e., a diameter of 10 mm, and a size of inch) (D2 in FIG. 12) and a drawing pipe with an outer diameter of 20 mm (D1 in FIG. 12) pass through the faucet installation device. Also, two hoses with joints (i.e., a size of G1/2) pass through the faucet installation device. According to basin faucets, two hoses with joints (i.e., a diameter of 10 mm, a size of inch) pass through the faucet installation device.

[0068] A disassembly method of the faucet installation device is as follows. Step 1, loosening the screw A5 locked to the base 1 and the faucet A. Step 2, taking out the faucet A. Step 3, removing the hoses (i.e., the water pipes A7). Step 4, loosening the second locking rod 32. Step 5, loosening the first locking rod 31. Step 6, moving the first locking rod 31 to the movable state to drive the pressing block mechanism 2 to be in the folded state. Step 7, taking out the pressing block mechanism 2 from the through hole of the countertop C and taking out a basin. The disassembly method is simple and convenient to provide the user with a better experience.

[0069] The fixing device B of this embodiment has the following advantages. First, the fixing device B is not limited by a height of the basin and has strong torsion strength and push-pull strength, provides a large space for pipes to pass through, and can achieve quick assembly and quick disassembly. Second, the structure is simple, and the assembly is easy. Third, the components are few, the structure is stable, and the fixing device B has cost advantages. Fourth, the space is large (such that the three hoses with joints (i.e., a diameter of 10 mm, a size of inch) and the drawing pipe with the outer diameter of 18 mm can be fit therein). Fifth, development cost is reduced.

[0070] FIGS. 13 and 14 are schematic views of the two basin faucets using the fixing device B.

[0071] The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure of is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
