[0024] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 4 As shown, this embodiment provides a faucet valve body assembly, including a valve seat, a bolt 13 and a nut fixing seat 14, wherein the valve seat includes an insert section 11 and an abutting section 12 connected to the upper end of the insert section 11, and specifically, the radial dimension of the abutting section 12 is larger than that of the insert section 11. Figure 5 , Figure 6 As shown, the insertion section 12 is used to be inserted into the mounting hole 21 of the table top 20, and at least one side is provided with a notch 101 that is smaller than the mounting hole 21 of the table top 20, that is, when the insertion section is inserted into the mounting hole of the table top, a space will be reserved at the position of the notch. Figure 3 , Figure 4 The dotted line a is Figure 5 , Figure 6The space enclosed by the hole wall of the mounting hole 21 , the side wall 111 and the dotted line a (the hole wall of the mounting hole 21 ) is the missing portion 101 ; the side wall 111 is the side wall 111 of the missing portion 101 .

[0027] The abutting section 12 is provided with a through hole 121 corresponding to the notch 101, the bolt 13 is passed through the through hole 121 of the abutting section 12, the nut fixing seat 14 is screwed on the bolt 13 and is located at the notch 101 of the insertion section 11, the nut fixing seat 14 has a radially protruding limiting convex portion 142, and the rotation of the bolt 14 drives the limiting convex portion 142 of the nut fixing seat 14 to be accommodated in the first position (such as Figure 3 The state shown) and the second position protruding from the notch 101 (as shown Figure 4 The state shown in the figure is switched between the two states. Figure 3 As shown, in the first position, all parts of the nut fixing seat 14 are in the notch 101, and when in the second position, as shown in FIG. Figure 4 As shown, the limiting protrusion 142 of the nut fixing seat 14 swings outwards so as to protrude from the notch 101 .

[0028] Continue to refer to Figures 5 to 8 As shown, the present embodiment further provides a mounting structure of a faucet and a countertop, the countertop 20 having a mounting hole 21, the faucet having the faucet valve body assembly described above, when the limiting protrusion 142 is in the first position, the insertion section 11 and the nut fixing seat 14 are inserted into the mounting hole 21 through the top of the countertop 20 and abut against the upper surface of the countertop 20 through the abutting section 12, so that the nut fixing seat 14 reaches the bottom of the countertop 20, and the rotation of the bolt 13 drives the limiting protrusion 142 of the nut fixing seat 14 to switch from the first position to the second position, so that the limiting protrusion 142 of the nut fixing seat 14 is stuck in the bottom of the countertop 20, as shown in FIG. Figure 7 shown.

[0029] That is, during installation, the nut fixing seat 14 is rotated until the limiting protrusion 142 is in the first position, so that the insertion section 11 and the nut fixing seat 14 can be inserted into the installation hole 21 through the top of the countertop 20 and abut on the upper surface of the countertop 20 through the abutting section 12, so that the nut fixing seat 14 reaches the bottom of the countertop 20, and then the bolt 13 is operated from above the countertop 20, and the limiting protrusion 142 of the nut fixing seat 14 is driven to switch from the first position to the second position through the rotation of the bolt 13, so that the limiting protrusion 142 of the nut fixing seat 14 is stuck in the bottom of the countertop 20, and the installation of the faucet and the countertop is realized; during disassembly, it is only necessary to operate the bolt 13 from above the countertop 20, and the limiting protrusion 142 of the nut fixing seat 14 can be switched from the second position to the first position through the reverse rotation of the bolt 13, so as to make way, and the faucet can be completely and quickly pulled out. The disassembly and assembly operations are all performed from above the countertop, which not only saves installation space and installation procedures, but also optimizes the installation method.

[0030] In this embodiment, the mounting hole 21 of the table 20 is a circular hole, and the missing portion 101 of the insertion section 11 is equivalent to cutting a "D"-shaped portion on the basis of a circle, that is, the missing portion 101 formed by the side wall 111 and the dotted line a (the hole wall of the mounting hole 21) is a space similar to a "D" shape. Of course, in other embodiments, the structure of the missing portion 101 of the insertion section 11 is not limited to this, and it can also be equivalent to cutting a sector-shaped portion on the basis of a circle.

[0031] The insertion section 11 is provided with two notches 101, which are located on opposite sides of the insertion section 11, such as the left and right sides; the bolts 13 and the nut fixing seats 14 are also provided in two groups, respectively matching the two notches 101, to form two groups of fixing structures; such a configuration makes the fixing more firm and the number is small. Of course, in other embodiments, one or more than two groups of the above fixing structures can also be used.

[0032] Specifically, in this embodiment, when the limiting protrusion 142 of the nut fixing seat 14 is in the first position, the connecting line b from the screw hole 141 of the nut fixing seat 14 to the end of the limiting protrusion 142 is parallel to the side wall 111 of the notch 101, so that it is accommodated in the notch 101; when the limiting protrusion 142 of the nut fixing seat 14 is in the second position, the connecting line from the screw hole 141 of the nut fixing seat 14 to the end of the limiting protrusion 142 is perpendicular to the side wall 111 of the notch 101, so that it protrudes from the notch 101.

[0033] Among them, the nut fixing seat 14 specifically includes a nut body 146 with a screw hole 141 and the limiting protrusion 142 extending radially outward from the nut body 146, and the nut body 146 is formed with an abutment plane 143 on the side away from the limiting protrusion 142, one side of the abutment plane 143 is connected to a circular arc segment 144 concentric with the screw hole 141, and the other side is connected to a radially protruding protrusion segment 145; when the limiting protrusion 142 of the nut fixing seat 141 is in the first position, it is affixed to the side wall 111 of the missing portion 101 through the circular arc segment 144, and when the limiting protrusion 142 of the nut fixing seat 14 is switched from the first position to the second position, the surface affixed to the side wall 111 of the missing portion 101 transitions from the circular arc segment 144 to the abutment plane 143, and is limited by the protrusion segment 145. The abutting plane 143 is equivalent to the section of the arc segment 144. When the limiting protrusion 142 of the nut fixing seat 14 switches between the first position and the second position, it can make a good transition; at the same time, when the limiting protrusion 142 of the nut fixing seat 14 switches from the first position to the second position, the convex segment 145 can prevent the nut fixing seat 14 from continuing to rotate in this direction, thereby playing a limiting role. Of course, in other embodiments, the limiting structure of the nut fixing seat 14 in the first position and the second position is not limited to this. For example, a limiting structure can be added to the insertion section 11 to achieve the limiting of the nut fixing seat 14.

[0034] Specifically, the swing direction of the limiting protrusion 142 of the nut fixing seat 14 from the first position to the second position is the same as the tightening direction of the bolt 13. With such a configuration, when the insertion section 11 is inserted into the mounting hole 21 of the table top 20 and the bolt 13 is tightened, the limiting protrusion 142 of the nut fixing seat 14 switches from the first position to the second position and is stuck into the bottom of the table top 20, and the cooperation between the raised section 145 of the nut fixing seat 14 and the side wall 111 of the notch 101 restricts the nut fixing seat 14 from continuing to rotate, and then the continued tightening operation of the bolt 13 realizes locking. When the bolt 13 rotates in the opposite direction, the limiting protrusion 142 of the nut fixing seat 14 immediately switches from the second position to the first position to realize unlocking. With such a configuration, the operation is simpler and the structural design is ingenious.

[0035] The insertion section 11 is also recessed with a recessed portion 112 near the abutting section 12, and a threading hole 122 corresponding to the recessed portion 112 is provided on the abutting section 12. In this way, the layout of the upper and lower circuits can be realized through the recessed portion 112 and the threading hole 122. For example, the power line or data line located above the table 20 can pass through the threading hole 122 and enter the lower part of the table 20 through the recessed portion 112. Of course, in other embodiments, if it is not necessary to layout the circuit, it is not necessary to open the recessed portion 112 and the threading hole 122.

[0036] A sealing gasket 17 is provided between the abutting section 12 and the upper surface of the table top 20 to achieve a tight fit between the abutting section 12 and the upper surface of the table top 20 .

[0037] The faucet further comprises a faucet member 15, which is sealed and sleeved on the outer peripheral side of the abutment section 12. Figure 8 As shown, a sealing ring 16 is sleeved on the outer peripheral side of the abutting section 12 , and a sealing assembly is achieved between the abutting section 12 and the faucet member 15 through the sealing ring 16 .

[0038] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
