Description

A kind of quick installation base device for basin faucet

Technical field

The utility model relates to the technical field of faucets, and in particular to a quick-assembly base device for a basin faucet.

Background technique

Faucets are essential hardware products in life. Faucets are often installed on sinks or basins. Due to the structural and material limitations of stainless steel sinks and ceramic basins, existing sinks and basins can usually only have through holes for installing faucets. After the connecting pipe at the bottom of the faucet passes through the through hole, a locking nut or Clips etc. fix the bottom of the faucet to the bottom of the sink or basin. When installing the faucet, you need to operate it under the sink or basin. Since the space in the under-counter cabinet of the sink or basin is limited, use a tool to tighten the locking nut. It is more difficult, making the installation operation time-consuming and laborious. Moreover, when repairing and replacing the faucet, it must be operated in the cabinet under the countertop, making the disassembly and assembly operation very inconvenient.

In response to the above problems, some fixtures that are convenient for installing and fixing faucets from above the sink or basin have recently appeared. For example, the patent announcement number is CN216131477U, and the patent document titled Top-mounted Faucet Fixture discloses a top-mounted faucet fixture. , including a faucet connecting pipe head, a ring-shaped piece locked in the faucet connecting head, and a fastening resistance piece symmetrically installed on the ring-shaped piece through bolts; the number of fastening resistance pieces is two pieces; the outer wall of the faucet connecting pipe head An external thread is provided, and the lower end of the faucet connecting pipe head extends downward to form a flared pipe mouth; that is, the diameter of the expanded pipe mouth is larger than the diameter of the faucet connecting pipe head; this faucet fixing device replaces the under-basin faucet of the traditional wash basin The fixing nuts, screws and other components need to be installed under the basin for the first time. When replacing or repairing the faucet next time, there is no need to operate it under the basin. It only needs to be operated on the basin. No need. Any tool, very easy.

Using this structure, it is necessary to provide several internal threaded holes in the pipe wall on the inner wall of the expanded pipe mouth, the ring-shaped member is installed in the expanded pipe mouth, and it is necessary to provide several internal threaded holes in the pipe wall on the outer wall of the ring-shaped member. The internal threaded holes in the ring wall are then connected and fixed with screws (optional parts) after the internal threaded holes in the ring wall are fitted with the internal threaded holes in the pipe wall. During installation, the internal threaded holes in the pipe wall need to be aligned with the internal threaded holes in the ring wall. Only after it is correct can it be locked and fixed with the additional screws. Since the flared nozzle at the lower end of the faucet connection head has been sleeved on the ring during installation, the threaded hole in the ring wall is blocked. Therefore, when screws are used for locking and fixing, the threaded hole in the pipe wall is in contact with the ring. The position of the threaded holes in the wall is difficult to align, making installation more troublesome. If not aligned, it is difficult to lock reliably, and it is easy to loosen after a period of use. In addition, the internal threaded holes in the pipe wall provided on the faucet connection head are also exposed, which affects the overall appearance. Moreover, the exposed internal threaded holes in the pipe wall are also prone to harbor dirt and evil and are difficult to clean.
