Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment installation technology, specifically to a pre-installed countertop fixation device for easy faucet installation and its application. Background Technology

[0002] Currently, installing faucets on bathroom countertops and kitchen sink countertops often presents difficulties. Taking bathroom countertops as an example, the faucet mounting holes are located inside the basin. When installing a faucet, it needs to be inserted into the mounting hole from top to bottom, and then the fasteners are tightened from below the countertop to secure it. Because the operating space under the countertop is narrow, and the location of the connector is not visible, installation is both laborious and time-consuming. Sometimes, installers even lie supine under the countertop to see the connector before proceeding with the installation. However, since they cannot straighten the faucet while lying down, another installer is needed to assist. Furthermore, the limited installation space and inconvenient use of tools can easily lead to loose faucet connections.

[0003] Chinese Patent Publication No. CN210216593U, entitled "Faucet Fixture, Faucet, and Basin," discloses a faucet fixture. In this fixture, the faucet body 113 abuts against a first surface 511 under gravity. A fastener 170 engages with the faucet fixture 200 and abuts against a second surface 513, initially positioning the faucet 100 on the mounting platform 510. Further tightening of the fastener 170 applies pressure to the second surface 513, thus securing the faucet body 113 and the faucet fixture 200 together relative to the mounting platform 510. However, this solution still requires installation from below the countertop using fasteners, failing to fundamentally solve the installation cumbersome problem. Therefore, its structure requires further improvement. Summary of the Invention

[0004] To address the above problems, this utility model provides a pre-installed countertop fixation device that facilitates faucet installation.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model discloses a pre-installed countertop fixing device for easy faucet installation, including a countertop and a fixing base. The fixing base is an axially penetrating hollow cylinder with an annular positioning flange extending radially from its upper outer periphery. The lower end face of the annular positioning flange forms a receiving surface that fits against the upper surface of the countertop. A fixing section is provided at the lower part of the fixing base, and the fixing section is inserted and fixed to the mounting hole of the countertop.

[0007] Preferably, the fixing section of the fixing base is connected to the mounting hole on the table by welding or bonding.

[0008] Preferably, a radially through threaded hole is provided on the side wall of the fixing seat near the upper opening, and the central axis of the radially through threaded hole is perpendicular to the central axis of the fixing seat.

[0009] Preferably, a protrusion is provided on the inner wall of the fixing seat along the axial direction, the protrusion extending downward from the upper opening of the fixing seat to the lower opening, and the radial through threaded hole is provided through the thickness direction of the protrusion.

[0010] Preferably, an annular groove is provided at the inner edge of the lower end face of the annular positioning flange, the groove opening faces downward, and the central axis of the annular groove coincides with the central axis of the fixed seat.

[0011] Preferably, it further includes a connector and a locking component; the connector is an annular body with an internal threaded hole, the internal threaded hole of which forms a threaded engagement with the external threaded section at the lower end of the fixed section, and at least two adjusting screw holes are evenly arranged circumferentially on the connector, the axis of each adjusting screw hole being parallel to the central axis of the connector; the locking component includes a screw portion that is threadedly engaged with the adjusting screw hole and a pressure head located at the end of the screw portion, the pressure head having an end face that contacts the lower surface of the platform, and by tightening the locking component, the pressure head generates a clamping force along the axial direction of the connector, forming a bidirectional clamping structure with the bearing surface of the annular positioning flange.

[0012] Preferably, the outer peripheral wall surface of the connector is provided with an axially extending groove structure. The groove structure is parallel to the central axis of the connector, forming an array of axially protruding ridges with equal spacing. This increases the surface friction coefficient and achieves an anti-slip function for manual screwing operation.

[0013] Preferably, the fixing seat has a tapered groove along its peripheral wall near the upper opening.

[0014] This utility model also discloses a washbasin, including a faucet body, a pre-installed countertop holder for easy faucet installation, and connecting screws. The faucet body passes through the axial through hole of the holder, and the connecting screw passes through a radial through hole on the side wall of the faucet body and is screwed into the radial through threaded hole of the holder, thereby connecting the faucet body and the holder together. A hot and cold water inlet pipe is connected to the bottom end of the faucet body.

[0015] This utility model also discloses a sink, including a faucet body, a pre-installed countertop fixing device for easy faucet installation, and connecting screws. The faucet body is inserted into the axial through hole of the fixing seat, and the connecting screws pass through the radial through hole on the side wall of the faucet body and abut against the conical groove of the fixing seat.

[0016] The technical advantages of this utility model's pre-installed countertop fastener for easy faucet installation are as follows:

[0017] 1. Pre-installation and convenient operation: The mounting base can be pre-embedded into the mounting holes in the countertop and secured by welding, bonding, or connectors / locking devices, achieving pre-installation of the fixture. Subsequently, the faucet body can be directly inserted into the through hole of the mounting base from above the countertop and locked laterally by connecting screws, completely eliminating the drawbacks of traditional installations that require operation in the narrow space under the sink, simplifying the installation process and reducing construction difficulty.

[0018] 2. Bidirectional clamping and uniform force distribution: By tightening multiple circumferentially distributed locking parts, the pressure head applies a vertically upward clamping force to the lower surface of the platform, forming a bidirectional clamping structure with the bearing surface of the annular positioning flange of the fixing seat. This ensures that the platform is uniformly pressed between the upper and lower force-bearing surfaces, avoiding the problem of local stress concentration caused by single-point locking, and significantly improving the vibration resistance and loosening resistance of the fixing device.

[0019] 3. Enhanced maintainability: The grooved structure on the outer wall of the connector facilitates manual adjustment by turning it, allowing for disassembly or tightness adjustment without the need for special tools. If it is necessary to replace the faucet or perform maintenance, it can be quickly disassembled and maintained simply by loosening the locking parts or connecting screws, avoiding the defect of traditional one-piece structures that require complete destructive disassembly.

[0020] In summary, this fastener, through its modular design, two-way clamping, and multi-point locking technology, achieves high efficiency, reliability, and long-term stability in faucet installation, making it particularly suitable for bathroom scenarios where ease of installation is a high priority.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0038] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a pre-installed countertop fastener for easy faucet installation, including a countertop 1 and a fixing base 2. The fixing base 2 is an axially penetrating hollow cylinder, with its upper outer periphery extending radially to form an annular positioning flange 21. The lower end face of the annular positioning flange 21 forms a receiving surface that fits against the upper surface of the countertop 1. A fixing section 22 is provided at the lower part of the fixing base 2, and the fixing section 22 is inserted and fixed to the mounting hole of the countertop 1.

[0039] Specifically, the fixing section 22 of the fixing base 2 is connected to the mounting hole of the tabletop 1 by welding. Both the fixing base 2 and the tabletop 1 are made of stainless steel, ensuring a firm fixation and preventing wobbling. When the tabletop 1 is made of ceramic, the fixing section 22 of the fixing base 2 is connected to the mounting hole of the tabletop 1 by adhesive bonding, such as resin bonding.

[0040] A radially through threaded hole 23 is provided on the side wall of the fixing seat 1 near the upper opening, and the central axis of the radially through threaded hole 23 is perpendicular to the central axis of the fixing seat 2. A protrusion 24 is provided axially on the inner wall of the fixing seat 2, extending downward from the upper opening of the fixing seat 1 to the lower opening, and the radially through threaded hole 23 is provided through the thickness direction of the protrusion 24. An annular groove 25 is provided at the inner edge of the lower end face of the annular positioning flange 21, with the groove opening facing downward, the central axis of the annular groove 25 coinciding with the central axis of the fixing seat 2, and a sealing ring is embedded in the annular groove 25 for waterproofing.

[0041] In this embodiment, the annular positioning flange 21 fits against the countertop via its lower end face, achieving automatic alignment during installation and eliminating the need for manual calibration. The split-type fixing section 22, designed (welded / bonded), is compatible with various countertop materials such as stainless steel and ceramic, increasing versatility by 60%. The axial protrusion 24 and the through-hole threaded hole 23 form a reinforced structure, increasing the thread engagement area by 40% and enabling it to withstand shear forces of ≥50 N·m, preventing loosening of the connection due to frequent faucet operation. Example 2

[0042] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, this embodiment provides a pre-installed countertop fastener for easy faucet installation, comprising: a countertop 1, a fixing base 2, a connector 3, and a locking component 4. The fixing base 2 is an axially penetrating hollow cylinder with an annular positioning flange 21 extending radially from its upper outer periphery. The lower end face of the annular positioning flange 21 forms a receiving surface that fits against the upper surface of the countertop 1. A fixing section 22 is provided at the lower part of the fixing base 2, and an external threaded section 221 is provided on the lower outer wall of the fixing section 22. The external threaded section 221 of the fixing section 22 extends from above the mounting hole of the countertop 1 to below. The connector 3 is an annular body with an internal threaded hole 31, which forms a threaded fit with the external threaded section 221 at the lower end of the fixing section 22. Two adjusting screw holes are evenly arranged circumferentially on the connector 3, and the axis of each adjusting screw hole is parallel to the central axis of the connector 3.

[0043] It should be noted that three or four adjusting screw holes can be provided on the connector 3. The adjusting screw holes are evenly distributed along the circumference to enhance stability.

[0044] The locking member 4 includes a screw part 41 that is threaded into the adjusting screw hole 32 and a pressure head 42 located at the end of the screw part 41. The pressure head 42 has an end face that contacts the lower surface of the platform 1. By tightening the locking member 4, the pressure head 42 generates a clamping force along the axial direction of the connecting member 3, forming a bidirectional clamping structure with the receiving surface of the annular positioning flange 21.

[0045] The outer peripheral wall surface of the connector 3 is provided with an axially extending groove structure 33. The groove structure 33 is parallel to the central axis of the connector 3, forming an axially convex ridge array with equal spacing, which increases the surface friction coefficient to achieve the anti-slip function of manual screwing operation.

[0046] This embodiment achieves quick installation and stable fixation of the faucet to the countertop through a two-way clamping structure and adjustable locking design. The specific workflow is as follows:

[0047] S1. Pre-installed fixing base and table positioning: The fixing section 22 of the fixing base 2 passes through the mounting hole of the table 1 from above, and the lower end face of the annular positioning flange 21 is attached to the upper surface of the table to form initial positioning; the external thread section 221 of the lower part of the fixing section 22 extends to the bottom of the table 1 and is pre-screwed with the internal thread hole 31 of the connector 3.

[0048] S2. Coordinated adjustment of connector and locking parts: Screw connector 3 into the external thread section 221 of fixing section 22, manually rotate connector 3, and use the groove structure 33 of its outer peripheral wall (protrusion height 1.5mm, spacing 2mm) to increase friction, and adjust to the distance between connector 3 and the lower surface of the table to about 2~5mm.

[0049] Screw the screw part 41 of the locking part 4 into the adjusting screw hole 32 of the connector 3 until the end face of the pressure head 42 contacts the lower surface of the table. Continue to tighten the locking part 4 so that the pressure head 42 applies axial clamping force (single point pressure ≥15N) to the table. At the same time, the connector 3 pulls the fixed section 22 upward through the thread engagement, forcing the bearing surface of the annular positioning flange 21 to be tightly pressed against the upper surface of the table, forming a bidirectional clamping.

[0050] S3. When the faucet is subjected to external vibration or torsion, the bidirectional clamping structure offsets the impact through the continuous clamping force of the pressure head 42. At the same time, the threaded engagement of the connector 3 generates a self-locking effect, preventing displacement between the fixed base 2 and the countertop 1. Multiple circumferentially distributed adjusting screw holes 32 (such as 2 to 4) allow for multi-point synchronous locking, dispersing local stress and avoiding countertop deformation or cracking caused by single-point overload.

[0051] This embodiment solves the pain points of traditional faucet installation, such as reliance on complex tools, poor adaptability, and easy loosening, through a two-way clamping mechanism and modular locking design. It achieves breakthroughs in stability, compatibility, and user experience, and is especially suitable for demanding residential and commercial scenarios. Example 3

[0052] like Figure 9 As shown, this embodiment further optimizes the structure of the fixing base 2 based on embodiment 2. A protrusion 24 is axially provided on the inner wall of the fixing base 2, extending from the upper and lower openings to the bottom. A radially through-threaded hole 23 penetrates the thickness direction of the protrusion 24 to enhance the strength of the threaded hole. During installation, the faucet body is fitted onto the fixing base 2, with its side wall radial through-hole aligned with the radially through-threaded hole 23 on the protrusion 24, and then tightened and fixed by connecting screws. Other structures, such as the connector 3 and locking element 4, are the same as in embodiment 2, and the locking element 4 achieves bidirectional clamping of the countertop. Example 4

[0053] like Figure 10 and Figure 11 As shown, this embodiment differs from Embodiment 1 in that a tapered groove 26 is provided along the circumferential wall near the upper opening of the fixing base 2. A ring of tapered grooves 26 is machined on the circumferential wall of the fixing base 2 near the upper opening (within 10mm of the top). The groove depth is 2-3mm, the taper is 15° (i.e., the groove wall inclination angle is 15°), and the tapered grooves 26 are continuously distributed circumferentially with a width of 5mm. A connecting screw (such as an M6 countersunk screw) is inserted into the radial through hole on the side wall of the faucet body. When tightened, the beveled surface of the screw head fits against the tapered surface of the tapered groove 26, generating radial clamping force through the self-locking effect of the tapered surface, rigidly connecting the faucet body to the fixing base 2.

[0054] The technical benefits are as follows: The conical groove 26, in conjunction with the beveled surface of the screw head, forms a wedge-shaped locking structure, increasing the torsional resistance of the connection between the faucet body and the fixing base 2 to ≥35 N·m (40% higher than in Example 1), effectively preventing circumferential displacement caused by frequent on / off operations. The 15° taper of the conical groove 26 allows the connecting screw to be tilted and locked within a range of ±5°, solving the installation difficulties caused by the angular deviation between the countertop opening and the faucet body, increasing the installation error tolerance by 50%, and is especially suitable for non-standard countertops or irregularly shaped faucets. The self-locking effect of the conical surface, combined with the anti-slip coating, reduces the probability of screw loosening by 90% under vibration environments (such as amplitude ≤0.5mm, frequency ≤30Hz), maintaining connection stability for more than 10 years. Example 5

[0055] like Figure 12 and Figure 13 As shown, this embodiment discloses a washbasin with a pre-installed countertop fastener for easy faucet installation. Specifically, this embodiment provides a washbasin including a faucet body 5, a pre-installed countertop fastener for easy faucet installation as described in Embodiment 2 or 3, and a connecting screw 6. The faucet body 5 is fitted onto the upper end of the fixing base 2, and its bottom is connected to hot and cold water inlet pipes 7. The side wall of the faucet body 5 has a radial through hole, through which the connecting screw 6 passes and is screwed into the radial through threaded hole 23 of the fixing base 2 to fasten the faucet to the fixing base. During installation, the fixing base 2 is placed in the mounting hole of the countertop 1, and the connecting piece 2 is tightened so that the pressure head 32 of the locking piece 3 pushes against the lower surface of the countertop, while the annular positioning flange 11 presses down on the upper surface of the countertop, forming a stable clamping. The grooved structure 23 facilitates manual tightening of the connecting piece 2, and the annular groove 15 can be embedded with a sealing ring to enhance waterproofing.

[0056] The washbasin provided in this embodiment significantly simplifies the faucet installation process by pre-installing a pre-installed countertop fastener for easy faucet installation. Specific technical advantages are as follows:

[0057] 1. Pre-installed retainer eliminates the need for further steps: The retainer is pre-embedded in the mounting holes on the countertop and is pre-secured by the two-way clamping structure of the locking mechanism (the annular positioning flange presses against the upper surface of the countertop, and the pressure head presses against the lower surface). When installing the faucet, simply insert the faucet body into the retainer above the countertop; no adjustment or locking operation is required from under the basin, making it especially suitable for scenarios with narrow or hard-to-reach spaces under the basin.

[0058] 2. Single-sided countertop installation design: The faucet body is aligned with the radial threaded hole of the fixing seat through the radial through hole on the side wall. It can be tightened by simply screwing in the connecting screw above the countertop, which completely avoids the tedious steps of screwing the nut below the countertop in the traditional installation and greatly reduces the difficulty of installation.

[0059] 3. The retainer is compatible with countertops of different thicknesses. Stable clamping is achieved by adjusting the clamping stroke of the locking element. It is also pre-installed and compatible with standard faucet structures, simplifying the replacement process later.

[0060] In summary, this utility model, through its pre-installed fixing device and single-sided operation design above the table, revolutionizes the traditional "top-and-bottom collaborative" installation mode into a "single-sided one-stop" installation, significantly improving construction efficiency and user experience. Example 6

[0061] like Figure 14 As shown, this embodiment discloses a sink with a pre-installed countertop fixture for easy faucet installation, including a faucet body 5, the pre-installed countertop fixture for easy faucet installation in embodiment 4, and a connecting screw 6. The faucet body 5 passes through the axial through hole of the fixing seat 2, and the connecting screw 6 passes through the radial through hole on the side wall of the faucet body 5 and abuts against the conical groove 26 of the fixing seat 2.

[0062] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
