as shown in fig. 1-3, the present embodiment illustrates an attachment assembly for a counter top faucet fixture that is configured to be placed on a sink counter top 200 to secure the faucet 100. The connection assembly mainly comprises a fixing base 300, a riveting-screwing coupling, a connecting sleeve 400 and a fastener.

The fixing base 300 includes a fixing sleeve 310 embedded in the through hole 210 of the table top 200 and a sleeve edge 320 disposed on the fixing sleeve 310 and attached to the table top 200. The retaining sleeve 310 is circular and the sleeve rim 320 is integrally formed with one end of the retaining sleeve 310.

The rivet-thread coupling includes a first connector and a second connector. The first connecting piece is provided with a riveting part and a first threaded connecting part, and the riveting part is used for being fixed with the table board 200. When fixing, a hole is drilled in the table 200 by a tool such as an electric drill, and the diameter of the drilled hole is adapted to the rivet. Accordingly, the second connector has a second threaded connection for mating with the first threaded connection to secure the sleeve rim 320 to the table top 200.

The connection sleeve 400 has a certain length such that the lower end thereof is embedded in the fixing base 300 and the upper end thereof has a sufficient length to be detachably connected to the water tap 100.

After the water tap 100 is connected to the upper end of the connection sleeve 400 and the lower end of the connection sleeve is embedded in the fixing base 300, the fastening member radially penetrates through the fixing base 300 and is abutted against the lower end of the connection sleeve 400 (see fig. 4 and 6), so that the connection sleeve 400 can be fixed and prevented from being separated.

By adopting the parts of the fixed seat 300, the riveting-threaded connector connecting sleeve 400 and the fastener, the operation can be carried out on the table top 200 during the assembly, and the whole assembly process does not need installation personnel to enter the space below the table top 200 for operation, so that the installation is convenient and fast, the limitation of the narrow space below the table top 200 can be avoided, and the operation difficulty is reduced. The invention is further illustrated by the following examples.

Referring to fig. 4 to 6, in the present embodiment, the first connector is a blind rivet nut 510, and the second connector is a bolt 520 adapted to the blind rivet nut 510.

In this embodiment, the sleeve rim 320 is an annular rim, and the annular rim surrounds the fixed sleeve 310 for a circle. The annular rim has a certain thickness (i.e. in the axial direction of the fixing sleeve 310) for increasing the strength, and the sleeve rim 320 is provided with a mounting hole 321 in the thickness direction for receiving and passing the rivet-screw coupling.

It should be noted that, in another alternative, the sleeve edge 320 may also adopt side lugs, and the number of the side lugs is set according to the number of the riveting-screwing couplings. If there are two rivet-thread couplings, a pair of opposite and symmetrically arranged side lugs is provided. If there are three or more riveting-screw connecting pieces, a corresponding number of side lugs are arranged, and the side lugs are uniformly distributed on the circumference of the outer wall of the fixing sleeve 310. The mounting hole 321 is formed on the side ear, and besides the mounting hole 321 is used for accommodating the riveting-screwing connector, a clamping groove, which is a half of the mounting hole 321, may be used, and details thereof are not described herein.

In the daily use process of the faucet 100, dirty water may flow onto the table top 200 inevitably, so that the dirty water may infiltrate into the gap between the sleeve edge 320 and the table top 200 at a certain probability, which is inconvenient to clean, is easy to breed bacteria, and may infiltrate into the lower part of the table top 200 even through the gap.

In order to avoid this, a first sealing sleeve 610 is provided between the sleeve rim 320 and the table top 200, and the first sealing sleeve 610 between the sleeve rim 320 and the table top 200 can be compressed when the sleeve rim 320 is fastened to the table top 200 by riveting-screwing, so that the waterproof and waterproof effect is achieved.
