The application claims priority to Chinese patent application No. 202322562045.5, filed on Sep. 21, 2023, the entire contents of which are incorporated herein by reference.
The present invention relates to the technical field of faucets, and in particular, to a basin faucet quick-mounting base device.
A faucet is a necessary hardware product in life, and the faucet is usually mounted on a water sink or a basin. Due to limitations of structures and materials of a stainless steel water sink, a ceramic basin, and the like, an existing water sink and basin generally can only be provided with a through hole for mounting the faucet, and after a connecting pipe at a bottom portion of the faucet passes through the through hole, the bottom portion of the faucet needs to be fixed to a bottom surface of the water sink or the basin by using a locking nut, a buckle, or the like. When the faucet is mounted, it is necessary to operate under the water tank or the basin, and since an inner space of an under-bench cabinet body of the water tank or the basin is limited, an operation is relatively difficult when a tool is used to tightly screw the locking nut, resulting in a time-consuming and labor-consuming mounting operation. Moreover, when the faucet is repaired and replaced, it is necessary to operate in the under-bench cabinet body, and therefore, disassembly and mounting operations are very inconvenient.
In view of the above problems, some fixing devices that facilitate mounting and fixing the faucet from above the water tank or the basin have recently emerged, for example, a patent document with the patent publication No. 216131477U and the patent title of a top-mounted faucet fixing device discloses a top-mounted faucet fixing device, including a faucet connecting pipe head, an annular member locked in the faucet connecting head, and fastening abutting members symmetrically mounted on the annular member through a bolt, where two fastening abutting members are mounted; and an outer wall of the faucet connecting pipe head is provided with an outer thread, and a lower end of the faucet connecting pipe head extends downward to form a flaring pipe opening, that is, a caliber of the flaring pipe opening is greater than a caliber of the faucet connecting pipe head. This faucet fixing device replaces a nut, a screw rod, and other components, used for fixing the faucet under a basin, of a conventional wash basin. After the fixing device only needs to be mounted under the basin for the first time, next faucet replacement or repair does not need to be operated under the basin and only needs to be operated above the basin without any tool, which is very convenient.
According to this structure, an inner wall of the flaring pipe opening needs to be provided with a plurality of pipe wall inner threaded holes, and the annular member is mounted in the flaring pipe opening. In addition, an outer wall of the annular member needs to be provided with a plurality of annular wall inner threaded holes corresponding to the pipe wall inner threaded holes, and then the annular wall inner threaded holes are connected and fixed to the pipe wall inner threaded holes through a screw (a component configured additionally) after the annular wall inner threaded holes are sleeved with the pipe wall inner threaded holes. During mounting, the pipe wall inner threaded holes need to be aligned with the annular wall inner threaded holes, and then the pipe wall inner threaded holes and the annular wall inner threaded holes are locked and fixed through the additionally configured screw. Since the flaring pipe opening at the lower end of the faucet connecting pipe head has been sleeved on the annular member during mounting, resulting in sheltering of the annular wall inner threaded holes, when the screw is used to perform locking and fixing, it is difficult to align positions of the pipe wall inner threaded holes with positions of the annular wall inner threaded holes, resulting in relatively troublesome mounting, difficult reliable locking, and easy loosening after a period of use time. In addition, the pipe wall inner threaded holes formed on the faucet connecting pipe head are also exposed to the outside, affecting overall aesthetics, and dirt is also easily hidden in the exposed pipe wall inner threaded holes, which is not easy to be cleaned.
To solve the above problems, a purpose of the present invention is to provide a basin faucet quick-mounting base device. A base body and an adapting connector that can be conveniently mounted from above a water sink or a basin are disposed, so that the adapting connector can be quickly and accurately inserted into the base body and then locked reliably, to ensure that a faucet body can be stably and reliably mounted; and a protective cover is disposed outside the base body for decoration and protection, so that the base body can be matched with existing faucet bodies with different specifications for mounting. The base body and the faucet body are aesthetic as a whole after being mounted and are convenient to be cleaned.
To achieve the above purpose, the present invention adopts the following technical solutions:

Referring to
A protective cover 9 is disposed outside the base body 1, and the protective cover 9 is composed of two split covers that are oppositely buckled together. A buckle and an inserting groove that facilitate opposite buckling are disposed between the two split covers, to facilitate buckling the two split covers to the adapting connector 2 on a bottom portion of the faucet body 8 after the faucet is fixed, so that the faucet is more aesthetic as a whole.
The screw mounting hole 12 is formed on a bottom portion of an inner side of the central through hole 11, two screw mounting holes 12 are provided, one connecting screw 3 is disposed in the two screw mounting holes 12 respectively to be connected to the locking member 5, and the locking member 5 is provided with a threaded hole matched with the connecting screw 3.
A spacer 10 is disposed between the locking member 5 and a bottom surface of the mounting table 6, the spacer 10 has a certain elasticity, the spacer 10 is matched with the locking member 5 to ensure that the locking member 5 is less prone to loosening after being tensioned by the connecting screw 3, shapes of the spacer 10 and the locking member 5 are the same, and the spacer 10 is provided with a relief hole for avoiding the connecting screw 3. The shape of the locking member 5 includes a C shape, a strip shape, or an irregular semicircle arc plate. A plurality of shapes may be set as required, so that a locking effect can be ensured, and passing of the connecting pipe matched with the faucet body 8 is not affected.
Two or more set threaded holes 14 are provided, and one set screw 7 is disposed in each of the set threaded holes 14. In the embodiment, preferably, three set threaded holes are provided. After the set screw 7 is screwed, a head portion of the set screw can tightly press against the spline 22 or the positioning ring groove 23, and a section of the positioning ring groove 23 is of a V shape or a T shape.
When the present invention is mounted, first, the sealing gasket 4 is placed in the sealing ring groove on the bottom portion of the base body 1, then the connecting screw 3 passes through the screw mounting hole 12 in the base body 1, the spacer 10 passes through a lower end of the connecting screw 3, then the locking member 5 is screwed to a threaded head portion of the connecting screw 3, the whole assembly is placed above a mounting hole of the mounting table 6, then the spacer 10 and the locking member 5 pass through the mounting hole of the mounting table 6 and are placed under the mounting table 6 (in a special condition, the spacer 10 and the locking member 5 may also be mounted on the connecting screw 3 from below the basin), and then a tool is used to screw the connecting screw 3 and tension the locking member 5 to tightly press the locking member 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 the adapting connector 2 is screwed to the bottom portion of the faucet body 8, and finally, the adapting connector 2 and the faucet body 8 are inserted into the central through hole 11 of the base body 1 as a whole.
