Description

A quick-install base device for a basin faucet Technical Field

[0001] The utility model relates to the technical field of faucets, in particular to a quick-install base device for a basin faucet. Background Art

[0002] Faucets are essential hardware items, often installed on sinks or basins. Due to structural and material limitations of stainless steel sinks and ceramic basins, existing sinks and basins typically only have through-holes for faucet installation. After the connecting pipe at the bottom of the faucet passes through the through-hole, a locking nut or clip is required to secure the faucet to the bottom of the sink or basin. Installation requires working under the sink or basin. Due to the limited space within the cabinet under the sink or basin, tightening the locking nut with tools is difficult, making installation time-consuming and labor-intensive. Furthermore, faucet repairs and replacements must be performed within the cabinet under the countertop, making assembly and disassembly very inconvenient.

[0003] In response to the above problems, some fixing devices have recently appeared that are convenient for installing and fixing faucets from above the sink or basin. For example, the patent document with patent publication number 216131477U and patent name "Top-mounted faucet fixing device" discloses a top-mounted faucet fixing device, including a faucet connecting pipe head, a ring-shaped part locked in the faucet connecting pipe head, and a fastening resistance member symmetrically installed on the ring-shaped part by bolts; the number of fastening resistance members is two; the outer wall of the faucet connecting pipe head is provided with an external thread, and the lower end of the faucet connecting pipe head extends downward to form a flared pipe mouth; that is, the diameter of the flared pipe mouth is larger than the diameter of the faucet connecting pipe head; this faucet fixing device replaces the nuts, screws and other components under the basin of the traditional washbasin for fixing the faucet. The fixing device only needs to be installed under the basin for the first time. The next time the faucet is replaced or repaired, there is no need to operate under the basin. It only needs to be operated on the basin, without any tools, which is very simple.

[0004] This structure requires the inner wall of the expanded pipe mouth to be provided with several internally threaded holes. The annular member is then installed within the expanded pipe mouth, and several corresponding internally threaded holes are then provided on the outer wall of the annular member. The internally threaded holes are then fitted together and secured with screws (separately provided). During installation, the internally threaded holes need to be aligned with the internally threaded holes before they can be tightened with the separately provided screws. Because the expanded pipe mouth at the lower end of the faucet connecting pipe head is already fitted onto the annular member during installation, the internally threaded holes are obscured. Therefore, when tightening with screws, it is difficult to align the internally threaded holes with the internally threaded holes, making installation cumbersome, difficult to secure, and prone to loosening after a period of use. Furthermore, the internally threaded holes in the pipe wall of the faucet connecting pipe head are exposed, affecting the overall aesthetics. Furthermore, these exposed internally threaded holes are prone to accumulating dirt and are difficult to clean. Utility Model Content

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0029] Referring to Figures 1-6, a basin faucet quick-install base device includes a base body 1, an adapter joint 2, a connecting screw 3, a sealing gasket 4 and a locking piece 5. The base body 1 is a circular or square flange structure as a whole. A central through hole 11 and a screw mounting hole 12 are provided in the base body 1. The central through hole 11 is used to pass the faucet connecting pipe. The sealing gasket 4 is provided on the bottom surface of the base body 1 for sealing contact with the top surface of the mounting table 6. The connecting screw 3 is provided in the screw mounting hole 12 and then tightens the locking piece 5. The adapter 2 is inserted into the base body 1 and fixed by pressing the spline 22 against the bottom surface of the mounting table 6. The spline 22 is provided with a locating ring groove 23, and the head of the set screw 7 is inserted into the locating ring groove 23 to compress the adapter 2, ensuring a better locking effect. A locating retaining ring 24 is provided between the main thread 21 of the adapter 2 and the locating ring groove 23. The lower end of the locating retaining ring 24 is connected to the upper end surface of the base body 1 for vertical positioning. The bottom of the base body 1 is provided with a sealing ring groove for installing the sealing gasket 4, which facilitates accurate installation of the sealing gasket 4. The base body 1 is made of plastic or metal materials such as copper and stainless steel; the surface of the base body 1 can be chrome-plated to ensure an attractive appearance.

[0030] The base body 1 is provided with a protective cover 9, which is composed of two separate covers that are buckled together. A buckle and slot are provided between the two separate covers to facilitate the buckling. After the faucet is fixed, the two separate covers can be buckled onto the adapter 2 at the bottom of the faucet body 8, making the faucet more beautiful as a whole.

[0031] The screw mounting hole 12 is arranged at the inner bottom of the central through hole 11. There are two screw mounting holes 12. A connecting screw 3 is respectively provided in the two screw mounting holes 12 to be connected to the locking member 5. The locking member 5 is provided with a threaded hole matching the connecting screw 3.

[0032] A gasket 10 is provided between the locking member 5 and the bottom surface of the mounting surface 6. The gasket 10 exhibits a certain degree of elasticity and cooperates with the locking member 5 to ensure that the locking member 5 is less susceptible to loosening after being tightened by the connecting screw 3. The gasket 10 and the locking member 5 have the same shape and are provided with a clearance hole to accommodate the connecting screw 3. The locking member 5 may be shaped like a C, a long strip, or an irregular semicircular plate. A variety of shapes can be used as needed to ensure a secure locking effect without interfering with the connection pipe that passes through the faucet body 8.

[0033] The tightening threaded holes 14 include more than two, and a tightening screw 7 is set in each of the tightening threaded holes 14. In this embodiment, three are preferably provided. After the tightening screw 7 is tightened, its head can press the spline 22 or the positioning ring groove 23. The cross-section of the positioning ring groove 23 is V-shaped or T-shaped.

[0034] When installing the present invention, first place the sealing gasket 4 into the sealing ring groove at the bottom of the base body 1, then pass the connecting screw 3 into the screw mounting hole 12 in the base body 1, pass the gasket 10 through the lower end of the connecting screw 3, and then screw the locking piece 5 on the threaded head of the connecting screw 3, place the entire assembly above the mounting hole of the mounting table 6, and then pass the gasket 10 and the locking piece 5 through the mounting hole of the mounting table 6 and place them under the mounting table 6 (in special cases, the gasket 10 and the locking piece 5 can also be installed on the connecting screw 3 from under the basin), then use a tool to tighten the connecting screw 3 to tighten the locking piece 5 so that it is pressed against the bottom surface of the mounting table 6, thereby fixing the base body 1 to the top surface of the mounting table 6. Then screw the adapter 2 into the bottom of the faucet body 8. Finally, insert the adapter 2 and faucet body 8 into the central through hole 11 of the base body 1. Use the set screw 7 to lock the adapter 2 and the base body 1. Finally, buckle the two separate covers to form a protective cover 9 on the base body 1. The installed faucet is stable and not easy to loosen, and the overall appearance is more beautiful. The device of the utility model can be installed from above the mounting table 6, making the installation process faster and more convenient.
