[0002] During the installation of the countertop faucet, the faucet is generally connected to the faucet through a fixing piece, and the faucet is fixed to the countertop through the fixing piece.

[0003] For example, the patent with publication number CN217352726U discloses a countertop faucet mounting structure and a faucet fixing part, which are used to install the faucet on the countertop, and at least one through hole is provided on the countertop, including a faucet, a mounting part and a first gasket, the outer diameter of the first gasket is larger than the aperture of the through hole, the mounting part is located below the first gasket, and the mounting part enters the through hole from above the countertop until the first gasket abuts against the countertop surface; a fixing part, including a connecting sleeve and a nut, the connecting sleeve is threadedly connected to the mounting part, the nut is located at one end of the connecting sleeve, the outer diameter of the nut is larger than the aperture of the through hole, the fixing part is connected to the mounting part from below the countertop, and the fixing part can achieve two-way connection according to the thickness of the countertop.

[0004] The problem with the above technology is that during installation, the user needs to first insert the installation part into the through hole from the top of the table, and then connect the fixing part to the installation part from the bottom of the table. During actual installation, the user needs to put his hand or body under the installation table to operate in order to complete the installation. For some installation tables with small space, it is difficult for the user to reach under the installation table, and it is difficult for the user to align the installation part and the fixing part, so the installation operation is relatively inconvenient.

[0005] Therefore, a mounting structure for a countertop faucet is proposed to solve the above technical problems. Utility Model Content

[0007] The technical solution adopted by the utility model to solve the problem is: a mounting structure of a countertop faucet, including a fixing seat and a nut screwed to the fixing seat, the fixing seat is used to connect the faucet, and also includes a supporting part and an operating part, the lower part of the operating part is connected to the supporting part, the upper part of the supporting part is provided with a limiting structure, the nut is embedded in the limiting structure, and the upper part of the operating part passes through the limiting structure and extends above the supporting part.

[0008] As a further improvement of the above technical solution, it also includes a handle, which is movably arranged on the upper part of the operating part.

[0009] As a further improvement of the above technical solution, it also includes a traction device, which is movably arranged on the upper part of the operating part.

[0010] As a further improvement of the above technical solution, a slot is provided at the bottom of the support portion, and an inserting portion is provided at the bottom of the operating portion, and the inserting portion is inserted into the slot.

[0011] As a further improvement of the above technical solution, the plug-in portion and the slot are riveted, pinned, welded, crimped, bent or injection-molded into one piece.

[0012] As a further improvement of the above technical solution, the limiting structure is groove-shaped, and the cross-sectional shape of the limiting structure is adapted to the outer shape of the nut.

[0013] As a further improvement of the above technical solution, a plurality of limiting openings are provided on the limiting structure, and a plurality of protrusions are provided around the outer peripheral wall of the nut, and the protrusions are clamped in the limiting openings.

[0014] As a further improvement of the above technical solution, S1. Pass the lower part of the fixing seat through the mounting hole of the table top, place the nut in the limiting structure, place the operating part and the supporting part under the table top, pass the traction device through the bottom of the fixing seat and extend it to the top of the fixing seat, and pull the traction device upward to move the operating part and the supporting part upward, so that the nut is close to the fixing seat; S2. When the nut abuts against the bottom of the fixing seat, connect the handle with the operating part, and rotate the handle to drive the supporting part to rotate, so that the nut is screwed to the fixing seat and the nut and the fixing seat are pressed against the mounting table top; S3. Disconnect the handle from the operating part, withdraw the traction device, the operating part and the supporting part from under the table top, disengage the limiting structure from the nut, and fix the faucet to the fixing seat, so that the faucet can be installed on the table top.
