Description

Technical Field

[0001] The present application belongs to the technical field of faucet components, and in particular relates to a top-mounted faucet fixing device that can be installed from above a countertop. Background Art

[0002] As we all know, traditional common faucets must be installed from the bottom of the countertop. This installation method has many disadvantages. Therefore, there are many structural designs for installing faucets from above the countertop. For example, China's authorized announcement number CN1102982 C invention patent discloses a quick-install faucet assembly, and the U.S. invention application publication number US2012 / 0137427A1 also discloses a faucet fixing structure and operation method. Both can install the faucet from the countertop, but there are still some disadvantages. Therefore, China's authorized announcement number CN203247650 U utility model patent discloses a faucet countertop installation device to improve the shortcomings of the above two patent technologies.

[0003] The above-mentioned faucet table mounting device mainly includes a mounting seat, a screw, a flip pressure ring and a lifting seat; the mounting seat is provided with a mounting hole, and a rod hole is provided on one side of the mounting hole; the screw can pass through the rod hole from above; the flip pressure ring is sleeved outside the screw, and its length is greater than the aperture of the mounting hole on the faucet table, and its width is smaller than the aperture of the mounting hole; the lifting seat is provided with a threaded hole that cooperates with the screw, and the flip pressure ring is eccentrically pivoted on the lifting seat, so that after it is flipped at a certain angle, it can pass through the mounting hole on a table from top to bottom; it can also include an anti-rotation structure, for example, a guide rod fixed to the bottom of the mounting seat and parallel to the screw and passing through the lifting seat, so as to prevent the lifting seat from rotating with the screw. In this way, the installer can rotate the screw from above the countertop to make the lifting seat drive the flip pressure ring to rise vertically until a part of it touches the bottom wall of the countertop. Continuing to rotate the screw can force the flip pressure ring to rotate from an inclined state to a horizontal state, and then tighten it to the bottom wall around the mounting hole of the countertop, thus completing the operation of installing the installation device from the countertop. Then, the faucet with cold and hot water inlet pipes can be installed from the countertop.

[0004] However, the structural design of the faucet table mounting device and the installation method thereof are still not perfect. For example, the flip pressure ring is a closed annular body. Although the water inlet pipe of the faucet can pass through the space enclosed inside, in order to ensure that the water inlet pipe can pass through smoothly, the annular body must be wide enough in size design. In particular, some faucets not only have two water inlets, such as a cold water inlet pipe and a hot water inlet pipe, but also a common pull-out faucet, which even includes a mixed water outlet pipe and a pull-out pipe. Therefore, the flip pressure ring has a minimum width limit in width design, but the width reduction is limited, which also leads to other problems. Because the mounting holes of the countertop have many different specifications and sizes, when the width of the flip pressure ring cannot be reduced, it also means that the width of the mounting device is too large and cannot be installed in the countertop mounting hole with a smaller aperture size. For example, common countertop mounting hole sizes are 38mm, 32mm and 25.4mm. The flip pressure ring will not be able to pass smoothly through the mounting hole with an aperture of 32mm or 25.4mm.

[0005] Secondly, although a clamping platform is added to the lifting seat of the above-mentioned faucet platform mounting device, which can be used for the bottom surface of the flip pressure ring to abut against, so that the clamping force borne by the pivot shaft between the flip pressure ring and the lifting seat can be reduced, the design of the clamping platform also relatively limits the inclination angle of the flip pressure ring, so that the penetration volume formed by the flip pressure ring in the tilted state cannot be reduced, and it cannot smoothly pass through the mounting hole with a smaller aperture, such as a mounting hole with an aperture of 32 mm or 25.4 mm.

[0006] Furthermore, even if the lifting seat does not have a clamping platform design, when the flip pressure ring is in the horizontal state, its inner surface and outer surface extend along the longitudinal direction. This also means that when it is flipped to the inclined state, its inner wall surface and outer surface both form an angle with the longitudinal axis. This not only reduces the internal space that allows the water pipes under the faucet to pass through, but also increases the size of the outer volume or diameter, making it more difficult to pass smoothly through smaller-sized installation holes on the countertop, such as the common minimum installation hole of 25.4 mm.

[0060] like Figures 1 to 4 As shown, the present application provides a first embodiment of a top-mounted faucet fixture. The fixture 1 of this embodiment can be pre-installed with a faucet. The faucet of this embodiment is a single-handle pull-out kitchen faucet 100. Figure 5As is well known, the faucet 100 generally comprises a body 101, within which a valve seat (not shown) is mounted, on which a mixing valve (not shown) is mounted. A control handle 102 is mounted on one side of the body 101 for actuating the mixing valve, and an outlet pipe 103 extends from the top, at the end of which a removable spray head 104 is mounted. Furthermore, a cold water inlet pipe 105, a hot water inlet pipe 106, and a mixed water outlet pipe 107 are fixedly connected below the valve seat, and the mixed water outlet pipe 107 is connected to a pull-out pipe 108, the other end of which is connected to the spray head 104. Therefore, there are four water pipes below the body 101, namely the cold water inlet pipe 105, the hot water inlet pipe 106, the mixed water outlet pipe 107, and the pull-out pipe 108. Thus, the cold and hot water from the cold water inlet pipe 105 and the hot water inlet pipe 106 can flow into the mixing valve of the valve seat respectively. The user can operate the control handle 102 to control the flow of the cold and hot water entering the mixing valve to the mixed water outlet pipe 107, or to adjust the temperature of the mixed water flowing to the mixed water outlet pipe 107. Since the pull-out faucet 100 is of conventional structure, it will not be described in detail here.

[0061] It should be emphasized that the fixing device 1 of this embodiment can be operated from above and then installed on a table 2, such as Figure 7 、 9 As shown, before the installation operation, the fixing device 1 and the pull-out faucet 100 must be preliminarily installed in advance, that is, the cold water inlet pipe 105, hot water inlet pipe 106, mixed water outlet pipe 107 and pull-out pipe 108 and other water pipes under the body 101 must be pre-installed through the fixing device 1, as shown in FIG. Figure 6 shown.

[0062] The fixing device 1 of this embodiment includes a base 10, a screw 20, a moving block 30 and a clamping ring 40; wherein:

[0063] The base 10 can be installed on the table 2 and has a seat 11 and a guide portion 12 extending from the bottom end of the seat 11 .

[0064] The screw rod 20 can be rotatably installed and positioned at the bottom ends of the seat portion 11 and the guide portion 12 of the base 10 .

[0065] The moving block 30 is screwed onto the screw rod 20 and can be restricted from rotating and moving vertically up and down along the guide portion 12 as the screw rod 20 rotates.

[0066] The tightening ring 40 is sleeved on the outer periphery of the guide portion 12 and is eccentrically pivoted with the moving block 30 so as to be pivotable between an inclined position and a tightening position. Figure 7 、 9 The clamping ring 40 can pass through a mounting hole 2a of the table 2 when in the inclined position, and when in the clamping position, is clamped to the bottom wall surface 2b of the table 2; the clamping ring 40 is formed by a tubular body 400 appropriately beveled, such as Figure 10 As shown, in this tilted position, the inner surface 41 and the outer surface 42 extend substantially in a vertical direction.

[0067] In this embodiment, when the tightening ring 40 is in the inclined position, the inclined angle θ thereof is approximately between 45 and 55 degrees, and is shown as 50 degrees in the figure. Generally speaking, this is a relatively large inclined angle.

[0068] In this embodiment, if Figure 6 As shown, the base 10 is provided with a closed pipe 13 and three open pipes 14 adjacent to the outer periphery of the closed pipe 13, extending longitudinally from the top of the seat portion 11 to the bottom end of the guide portion 12; the closed pipe 13 allows the pull-out pipe 108 to extend therethrough; the open pipes 14 allow the cold water inlet pipe 105, the hot water inlet pipe 106 and the mixed water outlet pipe 107 to extend therethrough respectively.

[0069] It can be understood that the pull-out tube 108 can move up and down or slide in the closed pipe 13 as the user operates the sprinkler head 104. Therefore, the independent design of the closed pipe 13 and other open pipes 14 is isolated from each other, which can ensure that the pull-out tube 108 will not contact and rub against other water pipes, thereby ensuring the smoothness of its pulling operation and extending its service life.

[0070] Furthermore, the open pipes 14 are designed to be arranged circumferentially along the periphery of the seat 11, so that the mixed water outlet pipe 107 can be installed in the open pipe 14 in the middle, and the cold water inlet pipe 105 and the hot water inlet pipe 106 are installed in the open pipes 14 on the two sides. Figure 2 As shown, the open pipe 14 located at the seat 11 is roughly in the form of a concave arc-shaped groove 141, and the open pipe 14 located at the guide portion 12 is roughly in the form of a long strip of concave arc-shaped groove 142. In this way, it can be ensured that the outer peripheral walls of each relative water pipe can be accommodated in each groove 141 and groove 142.

[0071] In this embodiment, the base portion 11 of the base 10 is provided with a longitudinal through-hole 111, and a pivot ear 121 is provided at the bottom end of the guide portion 12. The screw rod 20 extends through the longitudinal through-hole 111 and the pivot ear 121, allowing for in-situ rotation and positioning. The fixing device 1 may further include a limiting end sleeve 201, which can be fixedly attached to the bottom end of the screw rod 20 below the pivot ear 121. This prevents the screw rod 20 from longitudinally disengaging from the pivot ear 121, thereby allowing the screw rod 20 to rotate in-situ.

[0072] In this embodiment, the fixing device 1 may further include two rotating shafts 301 , which may be used to eccentrically pivot the tightening ring 40 on the periphery of the moving block 30 .

[0073] In this embodiment, if Figure 2 、 4 As shown, at least one stop wall 122 is formed on one side of the guide portion 12 of the base 10 ; the moving block 30 has at least one leaning wall 31 for leaning against the stop wall 122 to thereby be restricted from rotating. The cam 122 is a substantially rectangular piece of wood that is fixed to the guide rail 120 so that the cam 120 can be easily moved along the guide rail 120. The cam 122 is a substantially rectangular piece of wood that is fixed to the guide rail 120 so that the cam 120 can be easily moved along the guide rail 120.

[0074] In this embodiment, the longitudinal through hole 111 of the seat 11 includes a positioning hole 112 with a larger diameter, and the outer peripheral wall of the seat 11 is penetrated by a connecting hole 113 extending laterally to the positioning hole 112; the screw 20 has a screw head portion 21 and a screw portion 22 extending from the screw head portion 21, the screw head portion 21 can be accommodated in the positioning hole 112, the screw portion 22 can pass downward through the longitudinal through hole 111 and the pivot ear 121, and a driven gear 211 can be provided on the screw head portion 21. At the same time, a driving gear 202 is installed in the connecting hole 113, so that the driving gear 202 can be allowed to be rotated from the side of the seat 11 to engage and drive the driven gear 211, thereby driving the screw 20 to rotate, as shown in FIG. Figure 6 shown.

[0075] It is easy to understand that the driven gear 211 and the driving gear 202 can be designed as a helical gear combination, but are not limited to this. They can also be a bevel gear combination. According to this design, the user can use a specific tool from the side of the seat 11 to indirectly rotate the screw 20 through the engagement of the driving gear 202 and the driven gear 211.

[0076] As described above, the fixture 1 of this embodiment is designed to be able to be installed in various existing mounting holes 2a with different apertures, such as mounting holes 2a with apertures ranging from 25.4 mm to 38 mm, especially mounting holes 2a with a minimum aperture of 25.4 mm. Therefore, there are two technical means that can be adopted. First, before the fixture 1 is installed from above the countertop 2, it can be pre-assembled with the water pipes below the faucet 100. The advantage is that the water pipes below the faucet 100, namely the cold water inlet pipe 105 and the hot water inlet pipe 106, are connected to each other. The water inlet pipe 106, the mixed water outlet pipe 107, and the pull-out pipe 108 can utilize the joint portion with a smaller volume or diameter at the top end to pre-extend through the closed pipe 13 and each open pipe 14 of the fixing device 1, and then connect and fix to the bottom of the valve seat inside the main body 101, rather than being installed from top to bottom through the joint with a larger volume or diameter at the bottom end. Therefore, the size design of the clamping ring 40 can be greatly reduced, and even allow the clamping ring 40 to be very close to or touch each relative water pipe when in the tilted position, except for the pull-out pipe 108 located in the center. Second, the clamping ring 40 is allowed to have a larger inclination angle when in the inclined position, for example, between 45 and 55 degrees in the present embodiment. It can be clearly understood that the larger inclination angle design will facilitate the clamping ring 40 to pass through the mounting hole 2a with a smaller aperture, but its longitudinal projection area will also be relatively smaller, resulting in a smaller space available for longitudinal installation. However, by adopting an installation method in which the water pipes that have not yet been installed on the valve seat pass through the fixing device 1 from bottom to top and then connect to the valve seat, the water pipes are allowed to easily pass through the smaller longitudinal installation space without causing the problem of insufficient longitudinal installation space.

[0077] In addition, there is an extremely critical and innovative structural design, such as Figure 10 As shown, the clamping ring 40 is formed by appropriately beveling the tubular body 400. After the tubular body 400 is appropriately beveled, for example, at the aforementioned bevel angle of 45-55 degrees, when the clamping ring 40 is in the inclined position, its inner surface 41 and outer surface 42 extend substantially in a vertical direction, which has the following advantages:

[0078] The inner surface 41 of the clamping ring 40 can be extremely close to, or even completely smoothly fitted to, the outer peripheral walls of each relative water pipe, rather than being pressed against at a predetermined angle. This angle is likely to produce an obtuse angle or an acute angle. In particular, an acute angle is likely to cause greater squeezing or damage to the outer peripheral walls of each relative water pipe, such as shear stress damage on the outer peripheral walls. At the same time, the outer surface 42 extending in the vertical direction can also minimize the peripheral volume or body diameter of the clamping ring 40. Secondly, assuming that the inner surface 41 of the clamping ring 40 of this embodiment is in contact with the outer peripheral walls of each relative water pipe, the diameter of the clamping ring 40 passing through the mounting hole 2a of the table 2 is actually roughly only the diameter formed by the water pipes plus the two wall thicknesses h of the clamping ring 40. Therefore, compared with the design of the conventional clamping ring in which its inner wall surface extends at a certain tilt angle when in this tilted position, the clamping ring 40 of this embodiment can significantly maintain its outer diameter at a very small size when in this tilted position, so that it can be easily installed through the mounting hole 2a with the smallest aperture.

[0079] The clamping ring 40 has a long axis direction and a short axis direction, and the short axis direction is roughly the axial direction of the rotating shaft 301. The long axis direction and the short axis direction are perpendicular to each other. Therefore, the width of the two opposite sides of the clamping ring 40 in the short axis direction is smaller than the two opposite sides in the long axis direction. Since the clamping ring 40 is tilted up and down based on the two opposite sides in the long axis direction, the width design in the short axis direction must be smaller than the aperture of the mounting hole 2a. The width in the long axis direction must be smaller than the aperture of the mounting hole 2a in the tilted position so that it can pass through the mounting hole 2a longitudinally, and must be larger than the aperture of the mounting hole 2a in the clamping position so that it can be pressed against the bottom wall 2b of the table 2. Based on this, it can be understood that the greater the inclination angle of the clamping ring 40 in the inclined position, the greater the width design of the clamping ring 40 in the long axis direction can be. The advantage is that when the clamping ring 40 is changed from the inclined position to the clamping position, a sufficiently large width dimension can be formed in the long axis direction to meet the size requirements of the mounting hole 2a with the largest aperture in the installation and tightening. It can also form a sufficiently large tightening width or range between it and the bottom wall surface 2b of the table 2 to further ensure the stability of the installation and tightening. In other words, through the above-mentioned ingenious structural design of the clamping ring 40, it can be easily adapted to mounting holes 2a of various apertures, that is, it can be easily installed through mounting holes 2a with small apertures, and can also be firmly installed and fixed to mounting holes 2a with large apertures.

[0080] It should be noted that, depending on the different structural designs of the faucet, the seat 11 of the fixing device 1 can be directly abutted against the top wall 2c of the table 2, or can be abutted against other accessories, such as a bottom plate 109 of the faucet 100, as shown in FIG. Figure 7 、 9 As shown, the bottom plate 109 is against the top wall 2 c of the table 2 .

[0081] Furthermore, after the guide portion 12, the moving block 30, the clamping ring 40 of the fixing device 1 and the water pipes of the faucet 100 pass through the mounting hole 2a of the table 2, an operating hole 101a provided on the main body 101 can be used relative to the communicating hole 113 of the seat 11, as shown in FIG. Figure 8 As shown, the user can directly use a general tool or a special tool to rotate the driving gear 202 positioned in the communicating hole 113 through the operating hole 101a, thereby rotating the screw 20 to drive the moving block 30 and the upper clamping ring 40 to move longitudinally upward until they touch the bottom wall 2b of the table 2. Continuing to rotate the screw 20, the clamping ring 40 can be pivoted from the inclined position to the clamping position, thereby pressing against the bottom wall 2b to complete the installation and tightening operation.

[0082] As can be seen from the above, during the installation process, the user can easily perform the installation operation from above the countertop 2, installing and fixing the fixing device 1 together with the faucet 100 on the countertop 2. In particular, the screw rod 20 can be indirectly driven from the side through the operating hole 101a on the outer peripheral wall of the body 101 without first detaching the body 101 upward. However, this is not limited to this. The body 101 can also be detached upward away from the top wall 2c of the countertop 2 to expose the seat 11 due to its detachable design. The screw rod 20 can then be indirectly driven directly through the driving gear 202 in the communicating hole 113. There is even no need to provide the driving gear 202 and the driven gear 211. Instead, the screw rod 20 can be directly rotated by rotating the screw head portion 21 of the screw rod 20. After the fixing device 1 is tightened and fixed, the body 101 can be replaced in place. Therefore, the installation method is not limited to a single operation method.

[0083] like Figure 11 、 12 As shown, the present application provides a second embodiment of a top-mounted faucet fixture. The fixture 1a of this embodiment is substantially the same as the fixture 1 of the first embodiment, with the only difference being:

[0084] The fixing device 1a of this embodiment is suitable for a faucet 100a having only two water pipes, such as Figure 13As shown, for example, a basin faucet 100a with a single handle on the top does not have the pull-out spray head 104 of the first embodiment. Therefore, there is no mixed water outlet pipe 107 and pull-out pipe 108 mentioned above, only the cold water inlet pipe 105 and the hot water inlet pipe 106 mentioned above. When the cold and hot water from the cold water inlet pipe 105 and the hot water inlet pipe 106 flow into the valve seat and mixing valve inside the body 101, the control handle 102 on the top can be used to switch and adjust the mixing degree, and the mixed water is directly directed to the outlet pipe 103 for outflow.

[0085] As can be seen from the above, the base 10 of this embodiment only needs to be provided with two open pipes 14, and the open pipes 14 also extend longitudinally from the top of the seat portion 11 to the bottom of the guide portion 12, and respectively allow the cold water inlet pipe 105 and the hot water inlet pipe 106 to extend therethrough. Figure 14 shown.

[0086] In addition, since the guide portion 12 of this embodiment is designed with only two open pipes 14, its shape and structure are slightly different from the guide portion 12 of the first embodiment, so the structure corresponding to the guide portion 12 and the moving block 30 can be further simplified. Figure 15 As shown, further speaking, the guide portion 12 of this embodiment is designed with only one plane on the side relative to the moving block 30 to form a retaining wall 122. Relatively, the moving block 30 is also designed with only one plane to form a leaning wall 31. In this way, the effect of limiting rotation and guiding longitudinal slippage can also be achieved.

[0087] like Figure 16 、 17 As shown, the present application provides a third embodiment of a top-mounted faucet fixture. The fixture 1b of this embodiment is substantially the same as the fixture 1a of the second embodiment, with the only difference being:

[0088] This embodiment does not have the related structural designs of the driving gear 202 and the driven gear 211 of the first and second embodiments, but instead adopts a universal joint-shaped structural design.

[0089] Specifically, the screw head portion 21 of the screw rod 20 of this embodiment is formed with a driven shaft 212 in place of the driven gear 211, and is equipped with a driving shaft 203 in place of the driving gear 202. The driving shaft 203 can be hinged to the driven shaft 212, so that the driven shaft 212 and the driving shaft 203 can together form a universal joint 200. The driving shaft 203 allows the user to use a general tool or a special tool to rotate it at a predetermined tilt angle from above the seat 11, thereby driving the driven shaft 212 and, in turn, driving the screw rod 20. As for how the driving shaft 203 is rotated, as described above, it can be driven by temporarily detaching the body 101 upward to expose the seat 11, or it can be driven by providing the operating hole 101a on the outer peripheral wall of the body 101. The operating hole 101a can be a lateral hole or an oblique hole as required.

[0090] like Figure 18 As shown, the present application provides a fourth embodiment of a top-mounted faucet fixture. The fixture 1c of this embodiment is substantially the same as the fixtures 1a and 1b of the second and third embodiments described above, with the only difference being:

[0091] The base 10 of each of the above embodiments is a one-piece component, but is not limited to a one-piece component. For example, the base 10 of the present embodiment is a split component, that is, it is formed by a first component 10a and a second component 10b fixedly connected; and the first component 10a is mainly used to form the seat portion 11, and the second component 10b is mainly used to form the guide portion 12.

[0092] Secondly, the screw 20 of this embodiment can adopt a common screw shape, that is, a structure such as an inner hexagonal groove is formed on the screw head portion 21 so as to be directly turned by a common tool.

[0093] Furthermore, the moving block 30 of this embodiment can directly extend a protruding shaft 33 on each of its two sides so that it can be directly pivoted on two opposite sides of the clamping ring 40 without the need for the rotating shaft 301 design of the above embodiments.

[0094] It should be noted that the first component 10a and the second component 10b of this embodiment can also be an integrated component, such as Figure 19 shown.

[0095] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
