Description

Technical Field

[0001] This utility model relates to the technical field of faucet installation accessories, specifically to a quick-installation faucet base device. Background Technology

[0002] Most existing faucet base devices on the market require two separate parts, one above the countertop and one below, to be assembled during installation. This necessitates two installers: one person holds the main structure of the faucet above the countertop while the other tightens screws or threads below to secure the faucet to the countertop, which is time-consuming and labor-intensive.

[0003] Chinese patent document CN 110130444A discloses a faucet assembly, including: a base with a screw mounted on it, the screw's shank extending through the base; a mounting plate with the screw threadedly connected to it, wherein the base contacts the top surface of the countertop to be installed, and the mounting plate contacts the bottom surface of the countertop; and a faucet fixedly mounted on the base, with its inlet pipe extending through the base to connect to a water inlet line. While the installation method of this patent document is relatively secure, positioning the screw through the screw holes in the base requires the mounting plate to be installed in the mounting hole penetrating the countertop, so that the mounting plate is on the bottom surface of the countertop and the base is on the top surface. This still requires two people to install, or one person to install it using a difficult and complex hand-coordinated assembly method. Utility Model Content

[0004] In view of this, it is necessary to propose a quick-installation faucet base device to address the above-mentioned problems, overcome some of the shortcomings of the prior art, and solve the technical problem of how to simultaneously improve the convenience and reliability of faucet installation on perforated countertops.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model proposes a quick-installation faucet base device, including a mounting base, a screw, and a lifting and locking assembly. The mounting base is used to install on a washbasin with an installation through hole. The mounting base has a vertically penetrating base opening. The screw is located on one side of the base through hole and is rotatably connected to one side of the mounting base. During installation, the screw passes through the base opening. The lifting and locking assembly is used to rise with the screw to its upper installation limit position and then lock into the lower part of the installation through hole. The lifting and locking assembly includes:

[0007] The lifting shaft has a threaded through hole in the middle that mates with the screw. The lifting shaft moves up and down as it rotates relative to the screw through the threaded through hole.

[0008] The first locking lever is pivotally connected to one end of the lifting shaft; after the two ends of the first locking lever pass through the mounting through hole, they are both locked below the mounting through hole when the lifting shaft rises to the upper mounting limit position of the lifting shaft.

[0009] The second locking lever is pivotally connected to the other end of the lifting shaft; after the two ends of the second locking lever pass through the mounting through hole, they are locked below the mounting through hole when the lifting shaft rises to the upper mounting limit position of the lifting shaft.

[0010] The faucet base assembly also includes:

[0011] An anti-rotation structure is inserted into the base opening during installation. The two sides of the anti-rotation structure are respectively connected to the mounting base and the lifting shaft to form at least two connection structures, one of which is a movable connection structure.

[0012] Furthermore, after the two ends of the first locking lever pass through the mounting through hole, and when the lifting shaft rises to the upper mounting limit position of the lifting shaft, they are both locked onto the bottom surface of the table plate around the mounting through hole of the washing table.

[0015] Furthermore, both guide rods are vertically and movably connected to the lifting shaft.

[0016] Furthermore, the portion from one end of the first locking lever to the pivot center is the first rod portion, and the portion from the other end of the first locking lever to the pivot center is the second rod portion; the length of the first rod portion is greater than the length of the second rod portion;

[0017] The portion from one end of the second locking lever to the pivot center is the third rod, and the portion from the other end of the second locking lever to the pivot center is the fourth rod; the length of the third rod is greater than the length of the fourth rod.

[0018] Furthermore, the lifting and latching assembly also includes:

[0040] Example

[0041] like Figures 1-5 As shown:

[0042] This embodiment proposes a quick-installation faucet base device, including a mounting base 1, a screw 2, and a lifting and locking assembly. The mounting base 1 is used to install on a washbasin 100 with an installation through hole 1001. The mounting base 1 has a vertically penetrating base opening 11. The screw 2 is located on one side of the base through hole and is rotatably connected to one side of the mounting base 1. The screw 2 passes through the base opening 11 during installation. The lifting and locking assembly is used to rise with the screw 2 to the upper installation limit position and then lock into the lower part of the installation through hole 1001. The lifting and locking assembly includes:

[0043] The lifting shaft 3 has a threaded through hole 31 in the middle that mates with the screw 2. The lifting shaft 3 moves up and down by rotating relative to the screw 2 through the threaded through hole 31.

[0044] The first locking lever 4 is pivotally connected to one end of the lifting shaft 3; after the two ends of the first locking lever 4 pass through the mounting through hole 1001, they are both locked below the mounting through hole 1001 when the lifting shaft 3 rises to the upper mounting limit position of the lifting shaft 3.

[0045] The second locking lever 5 is pivotally connected to the other end of the lifting shaft 3; after the two ends of the second locking lever 5 pass through the mounting through hole 1001, they are locked below the mounting through hole 1001 when the lifting shaft 3 rises to the upper mounting limit position of the lifting shaft 3.

[0046] The faucet base assembly also includes:

[0047] The anti-rotation structure 6 is inserted into the base opening 11 during installation. The two sides of the anti-rotation structure 6 are respectively connected to the mounting base 1 and the lifting shaft 3 to form at least two connection structures, one of which is a movable connection structure.

[0048] Preferably, screw 2 is a long screw.

[0049] Optimized, such as Figure 6 As shown, after the two ends of the first locking lever 4 pass through the mounting through hole 1001, and when the lifting shaft 3 rises to the upper mounting limit position of the lifting shaft 3, they are both locked onto the bottom surface of the table plate around the mounting through hole 1001 of the washing table 100 (e.g., Figure 3 (as shown);

[0050] like Figure 6 As shown, after the two ends of the second locking lever 5 pass through the mounting through hole 1001, and when the lifting shaft 3 rises to the upper mounting limit position of the lifting shaft 3, they are both locked onto the bottom surface of the table plate around the mounting through hole 1001 of the washing table 100 (e.g., Figure 3(As shown); this further improves the stability and reliability of the faucet base device after installation.

[0051] Optimized anti-rotation structure 6 includes two guide rods; the two guide rods are located on both sides of the screw 2; the top of each guide rod is fixedly connected to the mounting base 1, and the lifting shaft 3 is provided with two guide rod through holes 32, which are located on both sides of the threaded through hole 31. The two guide rods are respectively movably inserted into the two guide rod through holes 32. This makes the structure of the faucet base device simpler, further improves the firmness and reliability of the faucet base device after installation, and reduces the difficulty of parts processing, making it suitable for mass production.

[0052] Ideally, both guide rods are vertically and movably connected to the lifting shaft 3; this simplifies the structure of the faucet base device and further improves its stability and reliability after installation.

[0053] Ideally, the portion from one end of the first locking lever 4 to the pivot center is the first rod portion 42, and the portion from the other end of the first locking lever 4 to the pivot center is the second rod portion 41; the length of the first rod portion 42 is greater than the length of the second rod portion 41.

[0054] The portion from one end of the second locking lever 5 to the pivot center is the third rod portion 52, and the portion from the other end of the second locking lever 5 to the pivot center is the fourth rod portion 51; the length of the third rod portion 52 is greater than the length of the fourth rod portion 51.

[0055] Optimally, the lifting latch assembly also includes:

[0056] The fixing rod 7 has two ends that are fixedly connected to the first rod part 42 and the third rod part 52, respectively. This improves the firmness and reliability of the faucet base device after installation, making it less likely for the first locking lever 4 and the second locking lever 5 to deform or shift after installation. It also ensures that the first locking lever 4 and the second locking lever 5 maintain the same direction when inserted into the installation through hole 1001, thus making installation easier.

[0057] In an optimized manner, the two ends of the fixing rod 7 are fixedly connected to the ends of the first rod 42 and the third rod 52, respectively; the screw 2 is located on one side of the through hole of the base and is rotatably connected to one side of the mounting base 1, which makes the installation of the screw 2 more secure. Since the first rod 42 and the third rod 52 are both long rods, this design makes the first locking lever 4 and the second locking lever 5 more secure and stable when locked below the mounting through hole 1001. The fixing rod 7 makes the first rod 42 and the third rod 52 less prone to deformation when locked under force, thereby improving the structural strength of the faucet base device and simplifying the structure.

[0058] Ideally, the second rod portion 41 is provided with a first bent portion 411 protruding toward the fourth rod portion 51. The first bent portion 411 is used to increase the weight of the second rod portion 41 to achieve the lever balance of the first locking lever 4. The fourth rod portion 51 is provided with a second bent portion 511 protruding toward the second rod portion 41. The second bent portion 511 is used to increase the weight of the fourth rod portion 51 to achieve the lever balance of the second locking lever 5.

[0059] Ideally, the pivot structure of the first locking lever 4 and one end of the lifting shaft 3, and the pivot structure of the second locking lever 5 and the other end of the lifting shaft 3 are symmetrically located on both sides of the screw 2.

[0060] Further optimized, the lifting shaft 3 has a circular shaft shape; this facilitates the mass production of the faucet base device, reduces the production cost of the faucet base device, and improves the structural strength.

[0061] Ideally, the lifting shaft 3 is perpendicularly connected to the screw 2, specifically: the virtual central axis of the lifting shaft 3 is perpendicular to the virtual central axis of the screw 2;

[0062] Both the first locking lever 4 and the second locking lever 5 are perpendicularly connected to the lifting shaft 3. Specifically, the virtual center axis (or length direction) of the first locking lever 4 is perpendicular to the virtual center axis of the lifting shaft 3, and the virtual center axis (or length direction) of the second locking lever 5 is perpendicular to the virtual center axis of the lifting shaft 3. This simplifies the structure and further improves the sturdiness and reliability of the faucet base device after installation.

[0063] Ideally, the screw 2 is provided with a limiting part 8; the limiting part 8 is located below the threaded through hole 31 of the lifting shaft 3, and is used as the lower installation limit position of the lifting shaft 3, so that the lifting shaft 3 cannot be lower than the limiting part 8 when it descends.

[0064] Preferably, the limiting part 8 is a limiting nut screwed into the screw 2; the limiting nut on the screw 2 can prevent operational errors that would cause the lifting shaft 3 to fall directly.

[0065] In a further optimized manner, the annular cylindrical part protruding in the middle of the mounting base 1 is the inner ring of the base. The inner wall of the inner ring of the base is connected to a fixed baffle (that is, the fixed baffle is part of one side of the mounting base 1). The fixed baffle has three holes, two of which are guide rod through holes 32 for embedding and welding the guide rod. The other large hole has a diameter slightly larger than the diameter of the screw 2, allowing the screw 2 to pass through the large hole, so that the lifting shaft 3 can be raised or lowered by rotating the screw 2.

[0066] Further optimized, the lifting shaft 3 also has three corresponding holes. Two of these holes are guide rod through holes 32, the diameter of which is slightly larger than the diameter of the guide rod. This allows the guide rod to freely allow the lifting shaft 3 to move vertically up or down while also preventing the lifting shaft 3 from deviating due to the restriction of the hole position. The third hole is a threaded through hole 31, the thread of which can be tightly fitted with the screw 2. Therefore, when the screw 2 rotates counterclockwise or clockwise, the lifting shaft 3 will passively move vertically up or down. The first locking lever 4 and the second locking lever 5 connected to the lifting shaft 3 will also move vertically up or down accordingly.

[0067] The installation process of this quick-installation faucet base device is as follows:

[0068] The first locking lever 4 and the second locking lever 5, which are pivotally connected to the lifting shaft 3 respectively, can rotate freely around the lifting shaft 3 at a certain angle. This reduces the projected diameter of the first locking lever 4 and the second locking lever 5 from a top-view angle, allowing them to pass through the mounting through hole 1001 from above the table. After passing through the mounting through hole 1001, the first locking lever 4 and the second locking lever 5, under the action of gravity, are tilted (e.g., ...). Figure 3 The dashed line indicates a structural change state. After naturally stretching and rotating, it reaches an unfolded state (such as...). Figure 3 (The dotted line shows another structural change state). Then, rotate the screw 2. The lifting shaft 3, the first locking lever 4, and the second locking lever 5 connected to the screw 2 will rise accordingly and eventually reach below the table. After tightening the screw 2, the ring part of the mounting base 1 clamps the table with the first locking lever 4 and the second locking lever 5 on the table and below the table, respectively, thereby realizing the fixed installation of the entire faucet base device.

[0069] Compared to ordinary faucet bases, the quick-installation faucet base device of this embodiment can save more than half of the installation time and save manpower: only one person is needed to install it, and no additional hands are required to operate under the countertop; it also simplifies the structure: the modular component connection avoids assembling various scattered parts on the installation site and reduces the number of installation steps.

[0070] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
