Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] Example 1 This embodiment refers to the appendix. Figures 1-7A quick-installation fixing structure for a faucet countertop is provided, including a base 1, a sleeve limiting plate 2, a sleeve 3, a fastener 4, and a control nut 5. The sleeve 3 is nested within the sleeve limiting plate 2, and a first thread 61 on the sleeve 3 engages with a second thread 62 on the sleeve limiting plate 2. The fastener 4 includes a connecting rod 41 and a locking foot 42 connected to each other. The connecting rod 41 passes through a hole 31 in the sleeve 3, and a third thread 63 at the tip of the connecting rod 41 engages with a fourth thread 64 on the control nut 5. The base 1 is fitted over the sleeve 3 and stacked on top of the sleeve limiting plate 2. The base 1 has a fifth thread 65 that engages with the first thread 61. The control nut 5 is configured to include a tool-free installation structure.

[0023] The base 1 and the sleeve limiting piece 2 serve as basic load-bearing components, used to cooperate with the mounting part of the countertop or faucet, providing support and positioning reference for the overall structure. Their shape is not limited to the cylindrical shape shown in the attached diagram; they can be constructed as a cuboid with an inner circle and an outer square, a polygon, or other shapes (as long as there is enough internal space to accommodate the rotation of the sleeve 3). The material can be metal, plastic, or composite material; the specific material is not limited, as long as it fulfills the load-bearing function.

[0024] The sleeve 3 can be partially or fully embedded in the base 1, as shown in the attached figure. The number of fasteners 4 and sockets 31 is not limited, but the number of sockets 31 should be greater than or equal to the number of fasteners 4. For example, it can be provided with one socket 31 and one fastener 4, or two sockets 31 and two fasteners 4, or two sockets 31 and one fastener 4, or three sockets 31 and two fasteners 4, and so on. A preferred configuration includes two fasteners 4 and two sockets 31, forming a locking mechanism with the underside of the table. The number of sockets 31 is not limited; it can be described as one socket or multiple sockets, with no fixed specific number. The shape of the locking foot 42 can be configured as a plate, claw, hook, etc.

[0025] The tool-free installation structure of the control nut 5 includes all structural designs that can be manually operated without special tools (such as wrenches or pliers), such as surface anti-slip structures including raised stripes, grid patterns, and rubber anti-slip layers, and labor-saving operation structures including symmetrically arranged lugs, extended handles, and foldable levers. Any tightening and loosening of the control nut 5 that can be achieved directly by hand falls within the protection scope of this feature. In this embodiment, the preferred implementation is shown in the accompanying drawings, where the tool-free installation structure is configured as a rotating handle 51 located on the side of the nut.

[0026] The installation and usage method of this application is as follows: like Figure 2As shown, first place the sleeve limiting piece 2 on the mounting platform, then insert the fastener 4 into the insertion hole 31 in the sleeve 3, and then align the control nut 5 with the thread of the fastener 4 and rotate to connect them. Next, rotate the assembled sleeve 3 and fastener 4 assembly into the sleeve limiting piece 2 to prevent it from falling off. After completion, align the base 1 with the first thread 61 of the sleeve 3 and screw it in. When we continue to rotate the base 1, the assembly of the sleeve 3 and fastener 4 will rotate upwards. When the engaging foot 42 of the fastener 4 is pressed against the bottom surface of the mounting platform, the engagement is achieved. Finally, the control nut 5 can be tightened to complete the installation.

[0027] It should be noted that the foregoing is only a preferred installation method. The claims do not limit the assembly order of the components (such as installing the sleeve limiting piece 2 first and then the sleeve 3 and fastener 4 assembly, or installing the sleeve 3 and fastener 4 assembly first and then the sleeve limiting piece 2). As long as the structural relationship described in the claims is ultimately formed, it is within the scope of protection.

[0028] Furthermore, the mutual cooperation and matching referred to in this application emphasize the structural correspondence, such as concave-convex fit, complementary shapes, etc., rather than the absolute precision of dimensions. Reasonable tolerances that do not affect the functional effect are allowed, and the same applies below.

[0029] Example 2 In this embodiment, a matching limiting structure 7 is provided between the insertion hole 31 and the connecting rod 41. The limiting structure 7 restricts the relative rotation between the connecting rod 41 and the insertion hole 31 of the sleeve 3, ensuring that the two maintain a relatively fixed positional relationship during installation or use, so that the fastener 4 can rise smoothly when the control nut 5 is rotated.

[0030] The specific fit of the limiting structure 7 may include: Shape-matching type: such as connecting rod 41 configured with a square, hexagonal or other polygonal cross section, and the socket 31 is a matching polygonal hole, which restricts circumferential rotation through complementary shapes; Elastic limiting type: The connecting rod 41 is provided with elastic protrusions such as spring pins, and the insertion hole 31 is set with positioning holes. During assembly, the elastic protrusions are engaged with the positioning holes to achieve limiting. In this embodiment, the limiting structure 7 specifically adopts a protrusion 71 provided on the connecting rod 41 and a recess 72 provided in the insertion hole 31.

[0031] Example 3 In this embodiment, a sealing gasket 8 is provided between the sleeve limiting piece 2 and the base 1.

[0032] The sealing gasket 8 is used to block the gap between the sleeve limiting plate 2 and the base 1, preventing liquid or impurities from seeping into the interior of the fixed structure or under the table through the gap between the two, thus avoiding component corrosion, table dampness or pipe contamination.

[0033] The sealing gasket 8 is preferably one with a certain degree of elasticity or deformation capacity, and possesses basic properties such as water resistance and aging resistance. It can be made of, but is not limited to, rubber, silicone, foam materials, metals (soft metals such as copper and aluminum, used in high-pressure sealing scenarios), composite materials (such as rubber-coated fiber layers), etc., as long as it can achieve the sealing function. The shape of the sealing gasket 8 can be designed according to the contact area between the sleeve limiting plate 2 and the base 1, such as ring, square, or irregularly shaped with notches, etc., and the thickness can be adjusted according to the gap size.

[0034] Example 4 In this embodiment, a clamping pad is provided at the bottom of the sleeve limiting piece 2.

[0035] The gasket is configured as a pad-like structure on the contact surface of the mounting hole, mainly used to increase the friction of the contact surface, buffer vibration, seal gaps, and protect the table surface. The material is usually an elastic or high coefficient of friction material, such as rubber, silicone, felt, sponge, leather, foam, etc. The thickness of the gasket is not limited, and its shape can be adapted to the contact surface.

[0036] Furthermore, a resistance structure is provided at the top of the locking foot 42. The resistance structure is used to increase the friction or resistance between the locking foot 42 and the contact surface, preventing the locking foot 42 from sliding or displacing due to external forces such as water flow impact and vibration during use, thereby enhancing the overall stability of the fixing structure.

[0037] The resistance structure can be configured to use a high coefficient of friction material, such as rubber, silicone, nitrile rubber, etc., on the top of the locking foot 42. The resistance is increased by the anti-slip properties of the material itself. These materials can be fixed by means of pasting, embedding, wrapping, etc., and come into direct contact with the contact surface to play an anti-slip role. The resistance structure can be configured as a shape-based resistance structure, with physical protrusions or textures designed on the top of the locking foot 42. The frictional resistance is increased by changing the shape. For example, there are small protrusions, including dot-shaped, columnar, and conical protrusions; textured structures, including grid patterns, stripes, wavy patterns, and sawtooth patterns; and resistance is enhanced by the interlocking of the texture with the contact surface. There are also irregularly shaped structures, including anti-slip patterns with alternating local depressions and protrusions, or complementary shapes that adapt to the texture of the countertop.

[0038] In a preferred embodiment, the resistance structure is configured as grooves 43. The grooves 43 are formed by providing dense, fine grooves on the top of the locking foot 42. By utilizing the mechanical interlocking or friction enhancement effect between the grooves 43 and the contact surface below the platform, the sliding resistance between the locking foot 42 and the contact surface is increased, thereby improving the stability of the fixing structure.

[0039] Example 5 In this embodiment, the base 1 is provided with a skirt 9 that covers at least the sleeve limiting piece 2. The skirt 9 is mainly used to cover the installation gap, increase the contact area with the tabletop, and prevent water or impurities from seeping in from the gap between the base 1 and the tabletop.

[0040] The skirt 9 refers to the flange structure extending outward or downward from the main edge of the base 1. It can be integrally formed with the base 1 or connected separately, and has a certain rigidity or support. The projected area of ​​the skirt 9 in the horizontal direction is not less than the projected area of ​​the sleeve limiting piece 2, that is, the extension range of the skirt 9 is sufficient to cover all or most of the sleeve limiting piece 2 inside it. When viewed from the outside, the sleeve limiting piece 2 is not exposed or only slightly exposed. In some other embodiments, the skirt 9 can completely wrap the sleeve limiting piece 2, that is, when viewed from the outside after installation, the sleeve limiting piece 2 is not exposed at all, and the skirt 9 completely covers the sleeve limiting piece 2.

[0041] In some embodiments, a pad may also be provided at the bottom of the skirt 9 to increase the friction of the contact surface, buffer vibration, seal gaps, and protect the table surface.

[0042] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
