Description

Technical Field

[0001] The utility model belongs to the technical field of faucet accessories and relates to a table-mounted component of a faucet. Background Art

[0002] Currently, common faucets are attached to countertops using bolts and nuts. During installation, the bolts are first secured to the faucet, then the water pipe and bolts are passed through the mounting holes in the countertop. A backing plate is then placed under the countertop over the bolts, and the nut is then fitted over the bolts and tightened with a wrench. However, due to the limited space and poor lighting under the countertop, installation is inconvenient.

[0003] In order to improve the convenience of faucet installation and operation, engineers have designed an installation component that can be used to install faucets above the countertop. For example, the Chinese patent document with the announcement number CN 208152161U discloses a quick-install structure for a faucet countertop, which includes a fixing seat, a bracket, a limiting rod and a bolt. The fixing seat is used to be fixedly connected to the housing of the faucet, the bracket is located below the fixing seat, the bolt is passed through the fixing seat and is threadedly connected to the bracket, and the limiting rod is fixed to the fixing seat and passed through the bracket. A clamping plate is hinged at both ends of the bracket, and a torsion spring is provided between the bracket and the clamping plate. The clamping plate expands outward relative to the bracket under the action of the torsion spring.

[0004] When installing the faucet, you first need to use your fingers to press the clamps at both ends of the bracket inward to overcome the elastic force of the torsion spring and bring the two clamps closer together; then, while keeping your fingers pressing the clamps, pass the clamps and the bracket through the mounting holes on the countertop, with the fixing seat located above the countertop; until the clamps and the bracket are completely through the mounting holes, the two clamps expand relative to the outside of the bracket under the action of the torsion spring; then use a wrench to rotate the bolt, and the rotation of the bolt drives the bracket to move upward until the clamps rest against the lower surface of the countertop, fixing the fixing seat on the countertop; finally, put the faucet on and fix it to the fixing seat.

[0005] The aforementioned quick-install structure on the faucet table allows installation operations above the countertop. However, during installation, the fingers must overcome the elastic force of the torsion spring to force the card inward, and the pressing state must be maintained for a period of time during the installation process, which can easily cause pain to the fingers. Therefore, the comfort and convenience of operation are still insufficient. To improve the comfort of installation operation, it is common practice to install rubber pads on the card or use torsion springs with a lower elastic modulus. The rubber pads are not difficult to install, but they increase the cost. The low elastic modulus of the torsion spring can easily prevent the card from opening smoothly. Utility Model Content

[0006] The purpose of the utility model is to address the above-mentioned problems existing in the prior art and to propose a counter-mounted assembly for a faucet, thereby solving the technical problem of insufficient operating comfort of the prior counter-mounted assembly.

[0007] The purpose of this utility model can be achieved through the following technical solutions:

[0008] A faucet countertop mounting assembly comprises a cylindrical base and a fixing block cooperating with the base for clamping the countertop, the base having a vertical through hole, a bolt passing through the through hole, and the fixing block being threadedly connected to the bolt. The assembly is characterized in that a vertically arranged mounting plate is provided on the bottom end of the base, the fixing block is connected to the mounting plate and can slide up and down along the mounting plate, the mounting plate is sheet-shaped and its bottom is bent from the outside to the inside, and there is a clearance between the wall surface of the through hole and the rod of the bolt, which allows the bottom end of the bolt to move toward the inside of the mounting plate, causing the bolt to tilt.

[0009] The inner side of the mounting plate refers to the space on the side of the mounting plate closest to the centerline of the base. The vertical sliding of the fixing block refers to the block sliding from the bottom to the top of the mounting plate (i.e., upward) and from the top to the bottom of the mounting plate (i.e., downward). Because the fixing block is attached to the mounting plate and threaded onto the bolt, turning the bolt drives the fixing block to slide up and down along the mounting plate.

[0010] The mounting holes in the countertop are typically cut on-site or at the countertop fabrication plant based on the dimensions of the faucet and its accessories purchased or selected by the customer. The size of the mounting hole should allow the fixing block to pass through when it is positioned at the bottom of the mounting plate, but not through the outer edge of the base. The faucet is installed at the construction site after the countertop is secured. To install the faucet, first turn the bolts to slide the fixing block along the mounting plate to the bottom of the plate. This allows the bolts to move inward, tilting the bolts due to clearance, allowing the fixing block to retract inward. Next, insert the mounting plate and the bottom of the bolts into the countertop's mounting holes. Once the base rests against the top surface of the countertop, turn the bolts again to slide the fixing block upward along the mounting plate, extending it outward and resetting the bolts. Continue turning the bolts until the fixing block rests against the bottom surface of the countertop. The fixing block and base are then clamped together and secured to the countertop, securing the faucet assembly to the countertop. Finally, thread the faucet hose through the base and connect the faucet housing to the base. The faucet is installed.

[0011] Since the bottom of the mounting plate is bent from the outside to the inside and the clearance is matched, when the bolt is rotated to enable the fixing block to slide along the mounting plate to the bottom of the mounting plate, the bolt tilts from top to bottom toward the inside of the mounting plate, and the fixing block automatically shrinks toward the inside of the mounting plate and remains in the retracted state. Moreover, the bolt is still inserted into the through hole for limitation during the process of tilting by utilizing the clearance, thereby avoiding the influence of the bolt shaking on the smooth sliding and inward contraction of the fixing block on the mounting plate. Therefore, there is no need to press the fixing block hard to retract the fixing block during the installation operation. Compared with the existing technology, the fingers of the mounting assembly will not feel pain due to pressing the fixing block hard during the installation process.

[0012] Therefore, this faucet installation assembly realizes the rapid installation of the faucet above the countertop, making the faucet installation convenient and quick. The bottom structure of the installation piece and the clearance enable the installer to drive the fixing block to retract and maintain the retracted state by turning the bolt, without the need to press the fixing block with fingers, thereby improving the comfort and convenience of the installation operation.

[0013] In the above-mentioned counter-mounted assembly of the faucet, the bent portion of the bottom of the mounting piece is tilted downward from the outside to the inside.

[0014] The tilted setting acts as a guide, reducing the possibility of the fixing block slipping and getting stuck at the bend. This allows for smooth installation, eliminating the need for finger manipulation of the fixing block and improving installation comfort and convenience. Furthermore, the tilted setting prevents the faucet hose from getting stuck at the bend.

[0015] In the above-mentioned faucet table mounting assembly, a slit is provided on the mounting plate along the sliding direction of the fixed block, the slit passes through the bottom surface of the mounting plate, the fixed block is inserted into the slit, and at least one side surface of the fixed block opposite to the mounting plate has an inner limit portion and an outer limit portion that are oppositely arranged, and the side edge of the mounting plate located at the slit is embedded between the inner limit portion and the outer limit portion of the corresponding side surface of the fixed block.

[0016] The fixing block is inserted into the slot and circumferentially positioned by the two side edges of the mounting plate at the slot. The side edges of the mounting plate at the slot are embedded between the inner and outer limiting portions, so that the fixing block is radially positioned by the inner and outer limiting portions. In this way, the fixing block is slidably positioned on the mounting plate. When the fixing block slides to the bottom of the mounting plate, it can remain in a retracted state, thereby ensuring comfortable and convenient installation operations. In addition, this arrangement is simple in structure and easy to manufacture, making it easier to ensure smooth sliding.

[0017] In the above-mentioned table-mounted assembly of the faucet, the side surface of the outer limit portion opposite to the inner limit portion is in a "ㄑ" shape in the up and down directions and is protruding toward the inner limit portion, and the middle turning point thereof is an arc transition; the side surface of the inner limit portion opposite to the outer limit portion is an inwardly inclined surface, and the inwardly inclined surface is inclined toward the inner side of the mounting plate along the direction from the top surface to the bottom surface of the fixing block, and the top surface and the bottom surface of the inner limit portion respectively transition to the arc of the inwardly inclined surface.

[0018] This can reduce the interference of the fixing block when sliding on the bottom of the installation piece, so that the fixing block can slide smoothly during the installation operation, ensuring the comfort and convenience of the installation operation.

[0019] In the above-mentioned faucet table mounting assembly, the hole wall surface of the through hole close to the center of the base is a semi-conical surface with a smaller top and a larger bottom, and the hole wall surface of the through hole away from the center of the base is a semi-cylindrical surface.

[0020] A clearance is formed between the rod of the bolt and the wall of such a through hole. When the fixing block slides to the bottom of the mounting plate, the head position of the bolt moves slightly and the bottom end of the bolt moves and tilts toward the inside of the mounting plate. The fixing block remains in a retracted state, thereby ensuring the comfort and convenience of the installation operation.

[0021] In the above-mentioned faucet counter-mounted assembly, the mounting piece is in the shape of an arc piece, and the bottom of the mounting piece has a plane sheet-shaped indented wall below the bend.

[0022] When the mounting plate is configured in a circular arc shape, a notch is defined between the two circumferential edges of the base. This notch allows for the faucet's water pipe connector to pass through the mounting plate, preventing it from becoming stuck on the recessed wall. This ensures smooth and convenient faucet installation. Furthermore, the circular arc shape of the mounting plate allows for radial alignment with the countertop's mounting hole, thereby securing the base securely on the countertop. A flat recessed wall enhances the stability of the fixing block in its retracted state.

[0023] In the above-mentioned counter-mounted assembly of the faucet, the side edge of the inwardly contracted wall at the slit has a convex strip protruding toward the inner side of the mounting piece.

[0024] The provision of the convex strip increases the side thickness of the indented wall at the slit, which can ensure the structural strength of the indented wall, stabilize the mounting plate structure, and ensure smooth sliding and stable positioning of the fixing block.

[0025] In the aforementioned faucet counter-mount assembly, the mounting plate forms an inclined wall at the bend, with both the top and bottom ends of the inclined wall having arc transitions. This allows the fixing block to slide smoothly along the inclined wall and into the retracted section, automatically retracting and extending the fixing block as the bolt rotates. This eliminates the need for finger manipulation of the fixing block, ensuring comfortable and convenient installation.

[0026] In the above-mentioned faucet table mounting assembly, the two side surfaces of the fixing block opposite to the mounting plate both have the inner limiting portion and the outer limiting portion, and the two side edges of the mounting plate located at the slit are respectively embedded between the inner limiting portion and the outer limiting portion of the corresponding side surfaces of the fixing block.

[0027] In this way, the positioning of the fixing block on both sides is achieved, the fixing block can be positioned more stably, and the force can be shared at the same time to avoid the installation piece from being broken due to excessive force, and the fixing block can be prevented from falling out from the inner retracted wall to the outside of the installation piece, avoiding pressing the fixing block with fingers, thereby improving the comfort and convenience of the installation operation.

[0028] In the above-mentioned faucet countertop mounting assembly, there are two bolts and each bolt is connected to the fixing block, so that the two fixing blocks can form two fixed positions with the countertop, thereby making the base and the faucet more stably fixed on the countertop.

[0029] In the above-mentioned faucet countertop mounting assembly, a locking cap is mounted and fixed to the bottom end of the bolt. The locking cap prevents the fixing block from falling out of the bottom end of the bolt, thereby ensuring that the height block remains retracted by the retracted wall during installation, ensuring comfortable and convenient installation.

[0030] Compared with the prior art, the utility model has the following advantages:

[0031] The coordination of the mounting plate's bottom structure and clearance allows the fixing block to be retracted and positioned within the positioning plate's bottom structure, eliminating the need for finger pressure on the fixing block and improving installation comfort and convenience. The angled bend creates a sliding guide, allowing the fixing block to slide smoothly onto the bottom of the mounting plate, ensuring comfortable and convenient installation. A slit is provided in the mounting plate, through which the fixing block is inserted and secured by internal and external stoppers. This simple structure facilitates manufacturing while ensuring smooth sliding and stable positioning. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0042] Example 1

[0043] like Figure 1 and Figure 2 As shown, a countertop mounting assembly for a faucet includes a cylindrical mounting sleeve 1, and the mounting sleeve 1 includes a cylindrical base 1a and a sheet-shaped mounting piece 1b. The mounting piece 1b is integrally connected to the inner edge of the bottom surface of the base 1a, and the mounting piece 1b is arranged vertically. A washer 4 is sleeved on the outer side of the mounting piece 1b, and the washer 4 rests on the bottom surface of the base 1a. Two bolts 3 are passed through the base 1a, and each bolt 3 is threadedly connected to a fixing block 2 for cooperating with the base 1a to clamp the countertop. The fixing block 2 is located below the base 1a. A locking cap 5 is threadedly connected to the bottom end of the bolt 3, and the locking cap 5 is used to prevent the fixing block 2 from falling out from the bottom end of the bolt 3. Combined Figure 3As shown, the mounting piece 1b is in the shape of an arc and is coaxially arranged with the base 1a. The mounting piece 1b forms a notch 1b1 between two side edges of the base 1a in the circumferential direction.

[0044] like Figure 1 and Figure 4 As shown, the bottom of the mounting piece 1b is bent from outside to inside, and the bend is tilted inward from top to bottom, forming an inclined wall 1b3 at the bend of the mounting piece 1b. The bottom of the mounting piece 1b has a flat sheet-shaped inward-retracted wall 1b4 below the inclined wall 1b3, and the inward-retracted wall 1b4 is parallel to the center line of the base 1a. The top and bottom ends of the inclined wall 1b3 on the mounting piece 1b are both arc-shaped. The inner side of the mounting piece 1b refers to the space on the side of the mounting piece 1b close to the center line of the base 1a, and the outer side of the mounting piece 1b refers to the space on the side of the mounting piece 1b away from the center line of the base 1a. Figure 3 and Figure 8 As shown, the fixing block 2 is connected to the mounting piece 1b and can slide up and down along the mounting piece 1b. The fixing block 2 can slide to the bottom of the mounting piece 1b and remain connected.

[0045] like Figure 1 and Figure 5 As shown, the mounting plate 1b is provided with two slits 1b2 arranged along the sliding direction of the fixing block 2, and the slits 1b2 are arranged one-to-one with the fixing block 2. The upper end of the slit 1b2 extends to the bottom surface of the base 1a, and the lower end of the slit 1b2 passes through the bottom surface of the mounting plate 1b. The side edge of the indented wall 1b4 located at the slit 1b2 has a ridge 1b5 protruding toward the inside of the mounting plate 1b. Figure 3 As shown, each fixing block 2 is inserted into the corresponding slit 1b2. The two sides of the fixing block 2 opposite to the mounting piece 1b have an inner limit portion 2a and an outer limit portion 2b arranged opposite to each other. The side edges of the mounting piece 1b located at the slit 1b2 are respectively embedded between the inner limit portion 2a and the outer limit portion 2b on the corresponding side of the fixing block 2. The inner limit portion 2a is located on the inner side of the mounting piece 1b, and the outer limit portion 2b is located on the outer side of the mounting piece 1b. Figure 4 and Figure 6 As shown, the side surface of the outer limit portion 2b opposite to the inner limit portion 2a is in a "ㄑ" shape in the vertical direction and protrudes toward the inner limit portion 2a. The side surface of the outer limit portion 2b opposite to the inner limit portion 2a includes an upper inclined surface 2b1 inclined toward the base 1a and a lower inclined surface 2b2 inclined away from the base 1a. The upper inclined surface 2b1 and the lower inclined surface 2b2 transition in a circular arc. Anti-slip straight lines are provided on the upper surface of the fixed block 2 to increase the static friction between the fixed block 2 and the table surface, so that the fixed block 2 and the base 1a are stably clamped on the table surface. Figure 4 and Figure 7As shown, the side surface of the inner limit portion 2a opposite to the outer limit portion 2b is an inwardly inclined surface 2a1, which is inclined toward the inner side of the mounting piece 1b along the direction from the top surface to the bottom surface of the fixing block 2, and the top surface and the bottom surface of the inner limit portion 2a respectively transition with the inwardly inclined surface 2a1 in a circular arc.

[0046] like Figure 4 and Figure 8 As shown, the inner side surface of the base 1a has an inserting portion 1a1, which has a vertical through-hole 1a3. The shank of the bolt 3 is inserted into the through-hole 1a3, and the head of the bolt 3 can abut against the top surface of the inserting portion 1a1. A clearance gap 6 is provided between the wall of the through-hole 1a3 and the shank of the bolt 3, allowing the bottom end of the bolt 3 to move inwardly toward the mounting plate 1b, causing the bolt 3 to tilt. The clearance gap 6 is formed as follows: the wall of the through-hole 1a3 near the center of the base 1a is a semi-conical surface with a smaller top and a larger bottom, which serves as the clearance surface 1a2. The wall of the through-hole 1a3 away from the center of the base 1a is a cylindrical surface. A clearance gap 6 is formed between the clearance surface 1a2 and the shank of the bolt 3. When the bottom end of the bolt 3 tilts inwardly toward the mounting plate 1b, the bolt 3 can tilt toward the clearance surface 1a2.

[0047] The mounting holes on the countertop are usually drilled at the construction site or countertop processing factory based on the size of the faucet and its accessories purchased or selected by the customer. The size of the mounting hole needs to be such that the fixing block 2 can pass through when it is located at the indented wall 1b4, but the outer edge of the bottom end of the base 1a cannot pass through. Since the fixing block 2 is slidably positioned on the mounting plate 1b, and the fixing block 2 is mounted and threaded on the bolt 3, when the bolt 3 is turned, the bolt 3 can drive the fixing block 2 to slide up and down along the mounting plate 1b. When installing the faucet, first turn the two bolts 3 so that the two fixing blocks 2 slide along the mounting plate 1b to the indented wall 1b4 respectively, as shown in the figure. Figure 8 As shown, the fixing block 2 is retracted relative to the base 1a, and the outer edge of the bottom surface of the base 1a protrudes from the outer side surface of the fixing block 2. Then, insert the mounting plate 1b and the bottom of the bolt 3 into the mounting hole of the countertop. When the washer 4 below the base 1a abuts against the upper surface of the countertop, rotate the two bolts 3 in sequence to slide the fixing block 2 upward along the mounting plate 1b. The fixing block 2 disengages from the retracted wall 1b4 and the inclined wall 1b3 and extends outward from the mounting plate 1b. Continue to rotate the bolts 3 until the fixing block 2 abuts against the lower surface of the countertop. The fixing block 2 and the base 1a are clamped and fixed to the countertop, that is, the faucet mounting assembly is fixed to the countertop. Finally, pass the faucet water pipe through the base 1a, and then connect the faucet shell to the base 1a to complete the faucet installation.

[0048] Due to the inward bend of the bottom of the mounting piece 1b and the clearance gap 6, when the fixing block 2 passes the inclined wall 1b3 and slides to the retracted wall 1b4, the fixing block 2 not only slides downward but also slides inwardly toward the mounting piece 1b, causing the fixing block 2 to retract and remain in the retracted state through the retracted wall 1b4. Therefore, during the installation operation, there is no need to press the fixing block 2 hard to retract and maintain the retracted state. Compared with the existing technology, during the installation process of this installation assembly, the fingers will not feel pain due to pressing the fixing block 2 hard. Therefore, this faucet installation assembly realizes the rapid installation of the faucet above the countertop, making the faucet installation convenient and quick. The bottom structure of the mounting piece 1b and the clearance gap 6 cooperate to retract the fixing block 2 and maintain the retracted state, without the need for pressing the fixing block 2 with fingers, thereby improving the comfort and convenience of the installation operation.

[0049] Example 2

[0050] The sliding positioning connection structure between the mounting plate 1b and the fixed block 2 is different, and the other structures are the same as those in Example 1. Each fixed block 2 is provided with protruding sliding columns on both sides of the circumference of the base 1a, and the sliding columns are cylindrical. The mounting plate 1b is provided with a sliding rail arranged along the sliding direction of the fixed block 2 corresponding to each sliding column. The cross-section of the sliding rail is U-shaped, and the section of the sliding rail at the bottom of the mounting plate 1b is located at the retracted wall 1b4. The two sliding columns on each fixed block 2 are respectively inserted into the corresponding sliding rail and can slide along the sliding rail, thereby realizing a sliding positioning connection. The sliding rail can be arranged at the slit 1b2, or it can be arranged on the outer surface of the mounting plate 1b. In this embodiment, since the cylindrical sliding column is subject to less interference, the bend can be an inclined wall 1b3 arranged at an angle, and a partial section of the sliding rail is located at the inclined wall 1b3, or it can be a vertical wall arranged vertically, and the inclined wall 1b3 is replaced by a vertical wall, and the vertical wall is perpendicular to the retracted wall 1b4.

[0051] Example 3

[0052] The position of the clearance gap 6 is different from that of the first embodiment, but the other structures are the same as those of the first embodiment. The wall surface of the through hole 1a3 away from the center of the base 1a is a semi-conical surface with a larger top and a smaller bottom. The wall surface of the through hole 1a3 near the center of the base 1a is a cylindrical surface. The clearance gap 6 is formed between the semi-conical wall surface of the through hole 1a3 and the shank of the bolt 3.

[0053] Example 4

[0054] A bolt 3 and a fixing block 2 are provided on the base 1a. This also enables the fixing of the mounting assembly on the table, but the fixing effect is not as good as that of the first embodiment.

[0055] Example 5

[0056] Each fixing block 2 is provided with an inner stopper 2a and an outer stopper 2b on only one side, and the rest of the structure is the same as in Example 1. This also enables a sliding, positionable connection between the fixing block 2 and the mounting plate 1b, except that when the bolt 3 rotates to drive the fixing block 2 to slide, the side edge of the mounting plate 1b at the slot 1b2 needs to withstand a greater torsional force.

[0057] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
