Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of home decoration and bathroom, in particular to a faucet base and a faucet. Background Art
[0002] Most common vertical faucets on the market today are secured to the countertop via a base-like structure, primarily through threaded connections, often supplemented by gluing. The most common faucet base design consists of two components: an upper base, a lower base, and a threaded connecting rod that secures the two. To accommodate this base design, the countertop where the faucet is mounted generally has mounting holes of roughly the same diameter. The upper and lower bases are often hollow rings or other similar structures, located above and below the mounting holes. The threaded connecting rod often consists of two or more parallel rods that pass through the countertop mounting holes.
[0003] However, the most commonly used faucet base method has the problem of inconvenient installation. Since it is often used to fix vertical faucets, the lower seat portion of the base used for fixing is often at an angle that is difficult to install. Considering the different installation heights of faucets, this faucet installation and fixing method is often difficult to operate. In order to improve this faucet fixing method, it is proposed to set the end of the threaded connecting rod at an upward angle. However, considering the normal function of the screw, it is still necessary to fix it by hand on the bottom side of the countertop during assembly, which still poses a considerable installation difficulty.
[0004] In summary, the existing faucet base for fixing the faucet has the technical problem of being difficult to install. Utility Model Content
[0005] The technical problem to be solved by the utility model is that the existing faucet base for fixing the faucet is difficult to install.
[0006] In order to solve the above problems, the present invention provides a faucet base, including an upper positioning seat, a lower positioning seat and a fastening rod, wherein the upper positioning seat is used to position and install the faucet body with the upper surface of the mounting table, and the lower positioning seat is used to position with the lower surface of the mounting table, and the fastening rod passes through the mounting through-hole of the mounting table, and its two ends are respectively connected with the upper positioning seat and the lower positioning seat, and the lower positioning seat includes a fixed anchor and a variable diameter anchor, and the fixed anchor is used to be detachably connected to the fastening rod, and the variable diameter anchor is located between the fixed anchor and the mounting table, and is movably sleeved on the outer periphery of the fastening rod, and the outer contour diameter of the variable diameter anchor expands when it is in a state of being against the fixed anchor, so that the lower positioning seat and the mounting through-hole form a limit to position the lower positioning seat on the lower surface of the mounting table.
[0007] The faucet base provided by the present invention adopts a positioning design different from the existing design, including an upper positioning seat and a lower positioning seat respectively located on both sides of the mounting through hole on the mounting table, and a fastening rod connecting the two. The lower positioning seat adopts a structure different from the existing design, mainly including a fixed anchor and a variable diameter anchor provided separately. The fixed anchor directly forms a fixed position with the end of the fastening rod. The variable diameter anchor is located between the fixed anchor and the table. When the fixed anchor is tightened by the fastening rod, the variable diameter anchor is against the end face of the fixed anchor, and the variable diameter anchor is made to be fixed by the matching end face structure between the two. The outer contour diameter is expanded so that its diameter is larger than the aperture of the mounting hole on the table, thereby obtaining the anchoring effect of the lower positioning seat at the outer edge of the mounting hole. Therefore, when the fastening rod is tightened by threads or other means, the base can be firmly positioned on the mounting table. With this design, the installation action can first be performed from one side of the upper end face of the mounting table, and due to the automatic expansion and anchoring effect of the lower positioning seat when the rod is tightened, there is no need for the installer to perform auxiliary actions from the other side of the mounting table, which greatly reduces the difficulty of installing the faucet and effectively solves the technical problem of the difficulty in installing the faucet base currently used to fix the faucet.
[0008] As a preferred solution, two parallel fastening rods are connected between the upper and lower positioning seats. The variable diameter anchor comprises two identically shaped variable diameter positioning blocks, each of which is provided with a through hole, each of which accommodates the passage of a fastening rod. This design employs a dual-rod fastening rod design, and the corresponding variable diameter positioning blocks utilize two separate block structures, each of which is provided with a through hole for accommodating the passage of a fastening rod.
[0009] As a preferred solution, the outer contour of the fixed anchor is arc-shaped, the top end face of the fixed anchor is arc-shaped, and the inclination direction of the arc-shaped slope is downwardly inclined along the radial increase direction of the mounting through hole; the bottom end face of the variable diameter positioning block has a reverse arc-shaped slope opposite to the inclination direction of the fixed anchor, and the variable diameter positioning block and the fixed anchor are abutted against each other through their respective slopes.
[0010] This design optimizes the mating end face structure between the fixed anchor and the variable diameter positioning block. The end faces of the two that abut each other both adopt an arc-shaped inclined surface structure, and the inclined surfaces on the fixed anchor and the variable diameter positioning block are inclined in opposite ways. In this way, when the fixed anchor is tightened by the fastening rod, the fixed anchor and the variable diameter positioning block are squeezed against each other. Under the interaction of the inclined surfaces, the variable diameter positioning block tends to slide relative to the radial outer edge of the fixed anchor, thereby achieving the effect of expanding the outer contour.
[0011] As a preferred solution, the outer edge of the arcuate inclined surface of the fixed anchor is provided with an arcuate groove, and the bottom end of the bottom inclined surface of the variable diameter positioning block has an arcuate boss that matches the arcuate groove. The concave-convex cooperation between the arcuate groove and the arcuate boss fixes the relative position of the fixed anchor and the variable diameter positioning block. This design further optimizes the end face structure design of the fixed anchor and the variable diameter positioning block. The arcuate groove and the arcuate boss are respectively provided on one side of the end face inclined surface of the two. Through this structural concave-convex cooperation, the relative position between the two is fixed after the relative sliding reaches the limit, thereby ensuring the stability of the lower positioning seat structure.
[0012] As a preferred solution, the through-hole in the variable-diameter positioning block is an elongated hole axially parallel to the radial direction of the mounting through-hole, providing space for radial relative movement between the variable-diameter positioning block and the fastening rod. This design optimizes the structural design of the variable-diameter positioning block. The elongated through-hole allows for a certain relative sliding margin between the fastening rod and the variable-diameter positioning block, allowing the variable-diameter positioning block to expand outward under the action of compression.
[0013] As a preferred solution, the two variable-diameter positioning blocks are connected by an elastic cushion structure, the two ends of which are respectively connected to the top end faces of the variable-diameter positioning blocks. The outer contour of the elastic cushion structure is arc-shaped, and is used to fit the outer edge of the bottom side of the installation through hole to increase the friction between the lower positioning seat and the installation table. This design further optimizes the design of the variable-diameter positioning block. The two variable-diameter positioning blocks are connected by an elastic cushion structure. First, it can provide soft contact between the variable-diameter positioning block and the table, increase friction and provide buffering, and can assist in the correct positioning of the two variable-diameter positioning blocks to ensure the correct contact angle when they collide with the fixed anchor.
[0014] As a preferred solution, the bottom surface of the elastic cushion structure is provided with plug-in bosses at both ends, and the top end surface of the variable diameter positioning block is provided with a socket that mates with the plug-in bosses. The elastic cushion structure and the variable diameter positioning block are plugged into each other. This design optimizes the connection between the elastic cushion structure and the variable diameter positioning block, connecting them through the plug-in bosses and sockets.
[0015] As a preferred solution, the fastening rods are all screws, and the fixing anchors are provided with threaded through-holes at positions corresponding to the ends of the two fastening rods, through which the fixing anchors engage with the fastening rods through the threaded through-holes. The upper positioning seat includes a pressure pad bushing, which is provided with screw holes at positions corresponding to the ends of the two fastening rods for limiting the positions of the fastening rod ends. The design of the fastening rods is optimized, preferably using screws, and the positioning method between the fastening rods and the fixing anchors also adopts threaded engagement. This design is simple to install and operate, and has good positioning effect.
[0016] As a preferred solution, the upper positioning seat also includes a sealing gasket located between the pressure pad ring and the top surface of the mounting table, and the pressure pad ring is also provided with an outer ring for protection. This optimizes the fit between the upper positioning seat and the table, and the addition of the sealing gasket provides contact cushioning and sealing.
[0017] The present invention also provides a faucet, comprising a faucet body and a faucet base for mounting and fixing the faucet body, wherein the faucet base is any of the faucet bases described above. Since the faucet base described above has the above beneficial effects, a faucet equipped with the faucet base should also have corresponding beneficial effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] A faucet base provided in this embodiment includes an upper positioning seat 1, a lower positioning seat 2 and a fastening rod 3. The upper positioning seat 1 is used to position and install the faucet body 5 on the upper surface of the installation table, and the lower positioning seat 2 is used to position on the lower surface of the installation table. The fastening rod 3 passes through the installation hole 4-1 of the installation table, and its two ends are respectively connected to the upper positioning seat 1 and the lower positioning seat 2. The lower positioning seat 2 includes a fixed anchor 2-2 and a variable diameter anchor 2-1. The fixed anchor 2-2 is used to be detachably connected to the fastening rod 3. The variable diameter anchor 2-1 is located between the fixed anchor 2-2 and the installation table, and is movably mounted on the outer periphery of the fastening rod 3. The outer contour diameter of the variable diameter anchor 2-1 expands when it is in a state of being against the fixed anchor 2-2, so that the lower positioning seat 2 and the installation hole 4-1 form a limit to position the lower positioning seat 2 on the lower surface of the installation table.
[0039] In this embodiment, the faucet base adopts a positioning design different from the existing design, including an upper positioning seat 1, a lower positioning seat 2 and a fastening rod 3 connecting the two, which are respectively located on both sides of the mounting through hole 4-1 on the mounting table. The lower positioning seat 2 adopts a structure different from the existing design, mainly including a fixed anchor 2-2 and a variable diameter anchor 2-1 set separately. The fixed anchor 2-2 directly forms a fixed positioning with the end of the fastening rod 3. The variable diameter anchor 2-1 is located between the fixed anchor 2-2 and the table. When the fixed anchor 2-2 is tightened by the fastening rod 3, the variable diameter anchor 2-1 and the end face of the fixed anchor 2-2 are abutted. Through the matching end faces between the two The structure expands the outer contour diameter of the variable diameter anchor 2-1, making its diameter larger than the aperture of the mounting hole 4-1 on the table, thereby obtaining the anchoring effect of the lower positioning seat 2 at the outer edge of the mounting hole 4-1, so when the tightening rod 3 is tightened by threads or other means, the base can be firmly positioned on the mounting table. With this design, the installation action can first be performed from the upper end face side of the mounting table, and due to the automatic expansion and anchoring effect of the lower positioning seat 2 when the rod is tightened, there is no need for the installer to perform auxiliary actions from the other side of the mounting table, which greatly reduces the difficulty of installing the faucet and effectively solves the technical problem of the existing faucet base for fixing the faucet.
[0040] refer to Figures 8-13 The following examples are described, Figure 8 for Figure 1 Schematic diagram of the structure of the variable diameter positioning block of the faucet base; Figure 9 for Figure 8 Schematic diagram of the structure on the other side of the middle reducer positioning block; Figure 10 for Figure 8 Schematic diagram of the top end surface structure of the middle reducer positioning block; Figure 11 for Figure 1 Schematic diagram of the structure of the fixing anchor of the faucet base; Figure 12 for Figure 11 A schematic diagram of the structure of the other side of the fixed anchor; Figure 13 for Figure 11 A schematic diagram of the structure of the other side of the fixed anchor;
[0041] The faucet base provided in this embodiment has two parallel fastening rods 3 connected between the upper and lower positioning bases 1 and 2. The variable diameter anchor 2-1 includes two identically shaped variable diameter positioning blocks 2-4. Each variable diameter positioning block 2-4 is provided with a through hole 2-5, each of which accommodates a fastening rod 3. The fastening rods 3 in this design utilize a dual-rod design, and the corresponding variable diameter positioning blocks 2-4 utilize two separate blocks, each of which is provided with a through hole 2-5 for accommodating a fastening rod 3.
[0042] The faucet base provided in this embodiment has an outer contour of the fixed anchor 2-2 in the shape of an arc, and the top end face of the fixed anchor 2-2 is in the shape of an arc slope, and the inclination direction of the arc slope is downwardly inclined along the radial increase direction of the mounting through hole 4-1; the bottom end face of the variable diameter positioning block 2-4 has a reverse arc slope in the opposite direction of the inclination direction of the fixed anchor 2-2, and the variable diameter positioning block 2-4 and the fixed anchor 2-2 are abutted and fitted through their respective slopes.
[0043] This design optimizes the mating end face structure between the fixed anchor 2-2 and the variable diameter positioning block 2-4. The end faces of the two that abut each other both adopt an arc-shaped inclined surface structure, and the inclined surfaces on the fixed anchor 2-2 and the variable diameter positioning block 2-4 are inclined in opposite ways. In this way, when the fixed anchor 2-2 is tightened by the fastening rod 3, the fixed anchor 2-2 and the variable diameter positioning block 2-4 are squeezed against each other. Under the interaction of the inclined surfaces, the variable diameter positioning block 2-4 tends to slide relative to the radial outer edge of the fixed anchor 2-2, thereby achieving the effect of expanding the outer contour.
[0044] The faucet base provided in this embodiment has an arcuate groove 2-8 disposed at the outer edge of the arcuate slope of the fixed anchor 2-2. The bottom end of the bottom slope of the variable-diameter positioning block 2-4 has an arcuate boss 2-9 that engages with the arcuate groove 2-8. The concave-convex interaction between the arcuate groove 2-8 and the arcuate boss secures the relative position of the fixed anchor 2-2 and the variable-diameter positioning block 2-4. This design further optimizes the end face structure of the fixed anchor 2-2 and the variable-diameter positioning block 2-4. The arcuate groove 2-8 and the arcuate boss are respectively disposed on one side of the end face slope of each. Through this structural concave-convex interaction, the relative position between the two is fixed after the relative sliding reaches the limit, thereby ensuring the stability of the lower positioning seat 2 structure.
[0045] In the faucet base provided in this embodiment, the through-hole 2-5 in the variable-diameter positioning block 2-4 is an elongated hole arranged axially parallel to the radial direction of the mounting through-hole 4-1, providing space for radial relative movement between the variable-diameter positioning block 2-4 and the fastening rod 3. This design optimizes the structure of the variable-diameter positioning block 2-4. The elongated through-hole 2-5 allows a certain relative sliding margin between the fastening rod 3 and the variable-diameter positioning block 2-4, allowing the variable-diameter positioning block 2-4 to move outward under the action of compression.
[0046] In the faucet base provided in this embodiment, the two variable-diameter positioning blocks 2-4 are connected by an elastic cushion structure 2-3. The two ends of the elastic cushion structure 2-3 are respectively connected to the top end surface of the variable-diameter positioning block 2-4. The outer contour of the elastic cushion structure 2-3 is arc-shaped, and is used to fit the outer edge of the bottom side surface of the installation through hole 4-1 to increase the friction between the lower positioning seat 2 and the installation table. This design further optimizes the design of the variable-diameter positioning block 2-4. The two variable-diameter positioning blocks 2-4 are connected by the elastic cushion structure 2-3. First, it can provide soft contact between the variable-diameter positioning block 2-4 and the table surface, increasing friction and providing a buffer. It can also assist in the correct positioning of the two variable-diameter positioning blocks 2-4, ensuring that the contact angle between them and the fixed anchor 2-2 is correct.
[0047] The faucet base provided in this embodiment has plug-in bosses 2-6 at both ends of the bottom surface of the elastic cushion structure 2-3. The top end surface of the variable diameter positioning block 2-4 is provided with a socket 2-10 that mates with the plug-in bosses 2-6. The elastic cushion structure 2-3 and the variable diameter positioning block 2-4 are plugged into each other. This design optimizes the connection between the elastic cushion structure 2-3 and the variable diameter positioning block 2-4, connecting them through the plug-in bosses 2-6 and the socket 2-10.
[0048] In the faucet base provided in this embodiment, the fastening rods 3 are all screws. The fixing anchors 2-2 are provided with threaded through-holes 2-7 at positions corresponding to the ends of the two fastening rods 3. The fixing anchors 2-2 are threadedly engaged with the fastening rods 3 through the threaded through-holes 2-7. The upper positioning seat 1 includes a pressure pad liner 1-2. The pressure pad liner 1-2 is provided with screw holes at positions corresponding to the ends of the two fastening rods 3 for limiting the ends of the fastening rods 3. The design of the fastening rods 3 is optimized, preferably using screws, and the positioning method between them and the fixing anchors 2-2 is also threaded. This design is simple to install and operate, and has good positioning effect.
[0049] The faucet base provided in this embodiment includes an upper positioning seat 1, a sealing gasket 1-3 positioned between a pressure pad ring 1-2 and the top surface of the mounting countertop. An outer ring 1-1 protects the pressure pad ring 1-2. The fit between the upper positioning seat 1 and the countertop is optimized, and the addition of the sealing gasket 1-3 provides contact cushioning and sealing.
