Description

Technical Field

[0001] This utility model relates to the field of faucet technology, and more specifically, to a mounting base for a countertop faucet and a countertop faucet. Background Technology

[0002] Currently, the installation of countertop faucets typically relies on mounting bases for quick installation and removal from the countertop. Existing installation methods mainly use bolts, threaded connections, or clamping devices to fix the base to the countertop. However, due to differences in countertop thickness and other installation environments, relying solely on bolts or threaded connections often lacks sufficient adaptability, resulting in faucets that cannot be securely installed on the countertop.

[0003] More importantly, installing the base often requires specialized screwdrivers, wrenches, or other disassembly tools to secure the base to the nuts or bolts below. Since these auxiliary tools are separate from the base body and operate as individual units, users not only need to carry and search for these tools during installation, but they are also prone to losing or damaging them due to improper placement, affecting subsequent maintenance. Furthermore, when the countertop space is narrow, the operation of traditional tools is restricted, and the disassembly force cannot be guaranteed, making the entire installation process more cumbersome and inconvenient for users.

[0009] As a further improvement, the tool placement assembly includes a waist-shaped main body extending longitudinally, a lateral extension integrally formed above the waist-shaped main body, and a pipe connection integrally formed below the waist-shaped main body.

[0010] As a further improvement, at least two plug-in pins are provided on the lateral extension, and the intermediate cylinder is provided with a mating groove for quick insertion of the plug-in pins; in the temporary placement state, the intermediate cylinder is positioned directly above the base.

[0011] As a further improvement, a snap-fit ​​portion is formed on the inner end side of the lateral extension, and a pipe fitting is detachably provided on the base. The pipe fitting is mated and adapted to the snap-fit ​​portion, and the pipe fitting extends longitudinally to define a channel for the entry and exit of external water pipes.

[0012] As a further improvement, the tube assembly extends through the base and connects to the tube joint; wherein the tube assembly and the waist-shaped main body are positioned opposite each other on different sides between the base and the fastener.

[0013] As a further improvement, the base includes a cylindrical part and a stepped part; the inner circumference of the cylindrical part forms a through hole for the entry and exit of an external water pipe, and the pipe fitting and tool placement assembly are respectively inserted through the through hole.

[0014] As a further improvement, the fastener is configured as a C-shaped locking ring, which has a mounting hole for screwing into the screw member.

[0015] As a further improvement, at least three windows are provided on the side of the cylindrical part, and each window is detachably equipped with a mounting plate.

[0016] As a further improvement, the base is fitted onto the upper surface of the tabletop, and the fasteners are fitted onto the lower surface of the tabletop.

[0017] This application also provides a mounting base for a countertop faucet, including a base for being disposed above the countertop, a fastener for being disposed below the countertop, and a screw member disposed on the base; the screw member is connected through the base and the fastener for adjusting the installation distance between the two; a second auxiliary installation tool is inserted between the base and the fastener, and the second auxiliary installation tool includes at least a tool placement assembly; the tool placement assembly is used to temporarily hold and support an external disassembly and assembly tool assembly, and allows the disassembly and assembly tool assembly to be removed from the tool placement assembly.

[0018] This application also provides a countertop faucet, including a faucet body and the aforementioned mounting base for the countertop faucet; after the disassembly and assembly tool assembly is switched to the use state, the base is locked and fixed inside the faucet body, and the bottom surface of the base is fitted against the bottom surface of the faucet body on the upper surface of the countertop.

[0019] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0020] 1. The mounting base for the countertop faucet of this application has a first auxiliary installation tool configured on the top of the mounting base, which is a disassembly and assembly tool assembly, and a second auxiliary installation tool is inserted between the base and the fastener, which is a tool placement assembly.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0033] Example

[0034] Combination Figures 1 to 6This embodiment provides a mounting base for a countertop faucet, including a base 1 for mounting above the countertop and a fastener 2 for mounting below the countertop. A screw 3 is provided on the base 1, passing through and connecting the base 1 and the fastener 2, for adjusting the installation distance between them. A first auxiliary installation tool is mounted on top of the base 1, and a second auxiliary installation tool is inserted between the base 1 and the fastener 2. The first auxiliary installation tool includes at least a disassembly / reassembly tool assembly 4, and the second auxiliary installation tool includes at least a tool placement assembly 5. The disassembly / reassembly tool assembly 4 is detachably attached to the tool placement assembly 5 or detachably attached to the base 1.

[0035] In this embodiment, the disassembly and assembly tool assembly 4 has a temporary placement state attached to the tool placement assembly 5, and a use state in which it is removed from the tool placement assembly 5 and used to assist in disassembly and assembly operations when the mounting base is installed on the table.

[0036] The aforementioned mounting base has a first auxiliary installation tool, specifically a disassembly and assembly tool assembly 4, positioned on top of it. A second auxiliary installation tool, specifically a tool placement assembly 5, is inserted between the base 1 and the fastener 2. The disassembly and assembly tool assembly 4 can be temporarily attached to the tool placement assembly 5. When in use, it can be removed from the temporary position to directly disassemble and assemble the base 1 and the fastener 2. This arrangement ensures that the tools required for installation, such as knives and wrenches, can always be attached to the base, eliminating the need for additional carrying and preventing loss.

[0037] When personnel need to install the base, there is no need to spend time searching for tools. Simply remove the disassembly and assembly tool assembly 4 from the tool placement assembly 5, and quickly rotate the screw to mate the base 1 with the fastener 2. Furthermore, the screw assembly 3 connects the base 1 and the fastener 2, and the distance between them can be precisely adjusted by rotating the screw according to the table thickness or installation requirements. At the same time, the tools used for disassembly and assembly are located precisely at the base position, greatly reducing the time required to retrieve and place tools and improving overall work efficiency.

[0038] Because the disassembly and assembly tool assembly 4 can be firmly attached to the tool placement assembly 5 when not in use, the tools are not likely to fall off even when flipped or moved in a confined space. This not only avoids the tools from being scattered and lost, but also reduces the friction and scratches between the tools and surrounding equipment and work surfaces, keeping the construction environment clean and reducing the risk of damage to equipment.

[0039] The screw 3 connects the base 1 and the fastener 2, and the installation height can be quickly adjusted by rotation, so that the mounting base can be adapted to tabletops of different thicknesses and shapes. With the addition of two auxiliary installation tools, even in environments with limited space or poor lighting, users can accurately tighten or loosen the tool assembly 4, which significantly reduces the difficulty of on-site construction and improves adaptability and reliability.

[0040] In this embodiment, the disassembly / assembly tool assembly 4 is detachably supported on the tool placement assembly 5. The detachable connection between the disassembly / assembly tool assembly 4 and the tool placement assembly 5 ensures that the tool is securely fixed within the mounting base when not in use, preventing it from slipping or being lost. When disassembly or assembly is required, simply remove the disassembly / assembly tool assembly 4 from the tool placement assembly 5 for direct use, significantly reducing the time and steps required for retrieving and placing tools.

[0041] Since the tools can be supported on the tool placement component 5 when not in use, and can be stored in an integrated manner with the base 1, the mess caused by placing tools randomly on the table or the ground in traditional construction is avoided, and the risk of tools being lost or damaged due to the complex construction environment is also reduced.

[0042] Furthermore, during installation, the disassembly and assembly tools are readily available, eliminating the need for additional searching or manual carrying, allowing users to quickly complete the disassembly and assembly of the screw component 3 and fastener 2. Simultaneously, with the tools positioned strategically and providing a wide field of vision, the screw adjustment function effectively improves locking accuracy and installation quality. Especially in confined spaces or poorly lit environments, the disassembly and assembly tool assembly 4 is fixed in place by the tool placement assembly 5, eliminating the need to bend over or stoop to find tools in confined spaces, significantly reducing operational difficulty and fatigue, and ensuring smooth installation.

[0043] like Figure 2 and Figure 3 As shown, in this embodiment, the disassembly and assembly tool assembly 4 includes a central cylindrical portion 41, and an outer wrench portion 42, an inner hexagonal portion 43, and multiple socket portions 44 integrally formed around the central cylindrical portion 41. Thus, the outer wrench portion 42, the inner hexagonal portion 43, and multiple socket portions 44 of different specifications are uniformly integrated onto a single central cylindrical portion 41, enabling the assembly to function as multiple commonly used tools. It can accommodate various specifications of bolts or fasteners 2, meeting the needs of different installation scenarios and significantly improving the tool's versatility and adaptability. Furthermore, the various functional components are integrally formed around the central cylindrical portion 41, resulting in a compact overall structure and small size, which facilitates its stable placement within the tool placement assembly 5, further achieving integrated storage with the mounting base.

[0044] like Figures 3 to 6As shown, in this embodiment, the tool placement assembly 5 includes a waist-shaped main body 51 extending longitudinally, a transverse extension 52 integrally formed above the waist-shaped main body 51, and a pipe connection 53 integrally formed below the waist-shaped main body 51. The waist-shaped main body 51 extends longitudinally, forming a stable structural support between the mounting base and the fastener 2, while providing sufficient support space to prevent shaking or falling during transportation and installation, thus improving overall reliability. Furthermore, the transverse extension 52, integrally formed with the waist-shaped main body 51, provides effective limiting and support when the tool assembly 4 is inserted, ensuring accurate positioning guidance during insertion and removal, preventing misinsertion, tilting, or jamming, and improving operational convenience and stability. In addition, the integrally formed pipe connection 53 facilitates pipe connection, auxiliary positioning, or assembly fixation, not only enhancing the overall structural functionality of the tool placement assembly 5 but also providing a certain degree of modular expansion capability, facilitating subsequent structural upgrades or combinations.

[0045] Specifically, the lateral extension 52 is provided with at least two insertion posts 54, and the intermediate cylindrical portion 41 is provided with a mating groove 45 for quick insertion of the insertion posts 54. Through the cooperation of the insertion posts 54 and the mating groove 45, the tool assembly 4 can be easily and quickly plugged into the tool placement assembly 5, achieving stable support without the need for additional fasteners 2 or snap-fit ​​mechanisms, thus improving ease of use and storage. Clearly, the plug-in structure has excellent guiding and positioning functions, allowing users to quickly insert and remove tools during actual operation, reducing operational obstacles caused by inaccurate positioning or jamming, thereby significantly improving the overall assembly efficiency of the mounting base.

[0046] In the temporary placement state, the intermediate cylinder 41 is positioned directly above the base 1. Positioning the intermediate cylinder 41 directly above the base 1 allows the disassembly and assembly tool assembly 4 to occupy a vertical position and be compactly stored when not in use. This effectively utilizes the previously unused upper space of the mounting base, avoids increasing the size of the device, and contributes to the compact design of the overall structure.

[0047] In this embodiment, a snap-fit ​​portion 55 is formed on the inner end of the lateral extension portion 52, and a pipe fitting 6 is detachably mounted on the base 1. The pipe fitting 6 and the snap-fit ​​portion 55 are mated and adapted to each other. Through the mating structure between the snap-fit ​​portion 55 and the pipe fitting 6, the tool placement component 5 and the pipe fitting 6 can be quickly installed and positioned, and the connection or separation of the waterway can be completed without the need for complex tools, which significantly improves the installation efficiency and is particularly suitable for application scenarios with variable construction environments or frequent disassembly and assembly.

[0048] Furthermore, the pipe assembly 6 extends longitudinally, correspondingly defining a channel for the entry and exit of external water pipes (such as pull-out pipes or cold / hot water inlet pipes). Preferably, the pull-out pipe of the faucet enters and exits through the channel, thereby distinguishing different inlet and outlet water pipes. Since the pipe assembly 6 is directly integrated into the mounting base, the hassle of needing to connect external water pipe interfaces during installation is avoided, greatly improving the convenience and efficiency of installation.

[0049] Furthermore, the pipe fitting 6 penetrates through the base 1 and extends into the pipe connection 53. The pipe fitting 6 penetrates through the base 1 and extends into the pipe connection 53, forming a continuous and sealed pipe path, allowing external water pipes to smoothly enter the base and connect to the faucet, ensuring uninterrupted water flow and structurally ensuring the closed-loop integrity of the entire system's water circuit.

[0050] The pipe fitting 6 and the waist-shaped main body 51 are positioned opposite each other on different sides between the base 1 and the fastener 2. Arranging the pipe fitting 6 and the waist-shaped main body 51 on opposite sides between the base 1 and the fastener 2 allows for spatial separation of the water channel functional area and the tool storage area, preventing interference between their respective structures and improving the overall orderliness and functional independence of the device. Furthermore, their opposing arrangement helps maximize functionality within limited installation space, facilitating adaptation to countertops of varying thicknesses, materials, or complex structures. Especially in scenarios with limited installation space, it effectively arranges pipes and tool components, enhancing installation adaptability.

[0051] like Figure 3 , Figure 5 and Figure 6 As shown, in this embodiment, the base 1 includes a cylindrical portion 11 and a stepped portion 12. Preferably, the cylindrical portion 11 and the stepped portion 12 are integral parts, and the stepped portion 12 is located on the outer side of the lower end of the cylindrical portion 11. This makes the structure of the base 1 more stable. The stepped portion 12 not only increases the contact area between the base 1 and the platform, but also enhances the stability of the base 1, avoiding tilting or instability during installation. The integral part design not only simplifies the overall structure of the base 1, but also reduces the complexity of manufacturing and assembly.

[0052] Specifically, the stepped portion 12 abuts against the inner wall of the faucet, defining the faucet body and the cylindrical portion 11 above the countertop. The bottom surface of the stepped portion 12 smoothly aligns with the bottom surface of the faucet body to fit and fix it to the upper surface of the countertop. On one hand, the stepped portion 12, by abutting against the inner wall of the faucet, stabilizes the faucet, further ensuring a firm connection between the faucet and the base 1, preventing the faucet from shifting or loosening due to external forces or vibrations. On the other hand, the stepped portion 12 relatively isolates the structure on the countertop above it, effectively defining the correct position. The stepped portion 12 provides a clear installation boundary for the structure on the countertop, reducing component misalignment or mismatch caused by installation errors, thereby ensuring installation accuracy.

[0053] Furthermore, the entire base 1 is located inside the faucet, and only the bottom surface of the step 12 smoothly connects with the bottom surface of the faucet body, ensuring a smooth transition between the faucet and the base 1. This provides a better sealing effect, preventing water leakage through the joint. In particular, it allows the mounting base and the faucet to be completely adapted to and fit against the upper surface of the countertop, which not only enhances the stability of the faucet but also ensures that the faucet is completely flush with the upper surface of the countertop after installation, thereby improving the overall neatness of the appearance.

[0054] In this embodiment, a through hole for external water pipes is formed on the inner circumference of the cylindrical part 11, and the pipe fitting 6 and tool placement assembly 5 are respectively inserted through the through hole. Obviously, the through hole opened on the inner circumference of the cylindrical part 11 allows water pipes to freely pass through and out, which can ensure a smoother connection between the water pipe and the valve core inside the faucet.

[0055] Furthermore, the fastener 2 is configured as a C-shaped locking ring, which has a mounting hole for screwing into the screw member 3. The C-shaped locking ring is located in the lower projection area of ​​the step portion 12. Clearly, the mounting hole and the screw member 3 are connected by a thread. The C-shaped locking ring, as a high-strength locking element, provides a uniform pressure distribution around the faucet mounting area, effectively preventing displacement of the faucet during use. The shape of the C-shaped ring allows it to firmly clamp the lower surface of the countertop and provide a more stable connection force, which helps improve the faucet's shock resistance and anti-loosening ability after installation.

[0056] The cylindrical part 11 has at least three windows on its side, and each window is detachably equipped with a mounting plate 13.

[0057] Furthermore, the base 1 is fitted onto the upper surface of the countertop, and the fastener 2 is fitted onto the lower surface of the countertop. This ensures that the base 1 is firmly attached to the upper surface of the countertop, while the fastener 2 is tightly attached to the lower surface, effectively preventing loosening during faucet installation. This ensures the faucet is stably and securely installed on the countertop, reducing problems such as leaks and loosening caused by insecure installation. The screw 3 can be adjusted according to different countertop thicknesses, adapting to various countertop conditions. Whether the countertop is thick or thin, it provides effective installation support. Users can flexibly adjust it according to their actual needs, avoiding the strict requirements of traditional installation bases on countertop thickness, and improving the product's versatility and adaptability.

[0058] The working principle of this mounting base is explained below:

[0059] When installing the faucet, first remove the disassembly and assembly tool assembly 4 from the tool placement assembly 5. Using the disassembly and assembly tool assembly 4, fasten the screw rod 3 through the threaded hole of the base 1, and install the pipe fitting 6 inside the base 1, completing the preparation for the installation of the countertop part. Begin the installation of the under-counter part. Using the disassembly and assembly tool assembly 4, insert the screw rod 3 into the through hole of the countertop, and screw the fastener 2 into the mounting hole, ensuring that the fastener 2 is adjusted and moved to fit the base 1 and is fixed to the countertop. After installation, return the disassembly and assembly tool assembly 4 to the tool placement assembly 5, or use it for one-time purposes, or store it yourself, etc.

[0060] In this embodiment, a mounting base for a countertop faucet is also provided, including a base 1 for mounting above the countertop, a fastener 2 for mounting below the countertop, and a screw 3 mounted on the base. The screw 3 passes through the base 1 and the fastener 2 to adjust the mounting distance between them. A second auxiliary installation tool is inserted between the base 1 and the fastener 2, and the second auxiliary installation tool includes at least a tool placement assembly 5. The tool placement assembly 5 is used to temporarily support and mount an external disassembly / removal tool assembly 4, and allows the disassembly / removal tool assembly 4 to be removed from the tool placement assembly 5.

[0061] Combination Figure 7 This embodiment also provides a countertop faucet, including a faucet body 7 and the aforementioned mounting base for the countertop faucet. After the disassembly and assembly tool assembly 4 is switched to the use state, the base 1 is locked and fixed inside the faucet body 7, and the bottom surface of the base 1 is fitted against the bottom surface of the faucet body 7 on the upper surface of the countertop.

[0062] As described above, once the disassembly and assembly tool assembly 4 is switched from its temporary state to its operational state, the user can directly use it to attach the base 1 to the faucet body without needing to carry or replace any other tools. After the base 1 is attached to the slot or thread already fixed inside the faucet body, the bottom surface of the base 1 and the bottom surface of the faucet body 7 are on the same plane. This allows for a one-time attachment to the countertop, completing the initial positioning and locking of the faucet and significantly reducing the traditionally cumbersome steps.

[0063] Furthermore, the base 1 and the bottom surface of the faucet body are simultaneously attached to the countertop, forming a flat and continuous force-bearing surface, avoiding loosening and leakage problems caused by misalignment or height differences between the base 1 and the body. This attachment method ensures that the faucet is subjected to more even force during use, effectively reducing the risk of loosening caused by water pressure impact or human operation, while also reducing the possibility of water leakage from the interface.

[0064] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
