[0037] See also Figure 1 , Figure 1 A schematic structural diagram of an embodiment of a mounting structure provided by the present invention is shown. The mounting structure is used to fix an object to be mounted on a thin wall provided with a mounting hole 31 , and mainly includes a mounting seat 20 , a limiting member 10 and a fastener 14 .

[0038] In this embodiment, the mounting structure is used on the faucet. Specifically, the faucet includes a faucet body and the above-mentioned mounting structure. The above-mentioned object to be installed is the faucet body. The mounting seat 20 is fixed to the faucet body by screwing, so that the faucet body can be fixed on the thin wall.

[0039] Furthermore, the present invention also provides a sink assembly, including a sink and the above-mentioned faucet, the sink countertop 30 forms the above-mentioned thin wall with the mounting hole 31, and the faucet is installed on the sink countertop 30 through the above-mentioned mounting structure.

[0040] Specifically, the mounting seat 20 is used to be fixedly connected to the object to be installed, and when it is placed in the mounting hole 31, it overlaps the front face of the thin wall; in this embodiment, the mounting seat 20 includes a lower part and an upper part with gradually increasing sizes, the lower part of which is used to be placed in the mounting hole 31, and the upper part is used to overlap the front face of the thin wall.

[0041] The thin-walled front side here refers to the upper surface of the sink countertop 30. Generally speaking, the sink will form a countertop structure extending outward around the top. The faucet can be installed on this horizontal countertop structure, and then the water inlet pipe is connected from the bottom of the sink countertop 30. Therefore, the thin-walled back side below refers to the lower surface of the sink countertop 30. The lower side of the sink countertop 30 generally has a cavity. In this embodiment, Figure 3 As shown, a mounting hole 31 is provided on the sink countertop 30. The mounting hole 31 is generally circular and is used to install a faucet for discharging water.

[0042] A through threaded hole is provided in the middle of the mounting base 20, which forms a faucet fixing hole 23. The pipe fitting of the faucet body is adapted to the size of the faucet fixing hole 23 and is also provided with an external thread. By screwing the faucet body into the faucet fixing hole 23, the faucet body can be fixedly connected to the sink countertop 30.

[0043] The stopper 10 has at least one projection on a plane perpendicular to the axis of the mounting hole 31 that is smaller than the size of the mounting hole. After passing through the mounting hole 31, it shifts position so that a portion of its body faces the back of the thin wall. After passing through the mounting hole 31, it reaches the lower position of the mounting seat 20 and is restrained by the mounting seat 20. The fastener 14 is screwed to the stopper 10 or the mounting seat 20 from the front of the thin wall, and applies force to the front of the thin wall, causing the stopper 10 to move toward the thin wall until it abuts the back of the thin wall.

[0044] Among them, the above-mentioned limiting member 10 has at least one projection on the plane perpendicular to the axis of the mounting hole 31 that is smaller than the size of the mounting hole 31, which means that when the limiting member 20 is projected (parallel projection) onto the plane perpendicular to the axis of the mounting hole 31 from any angle, there is at least one angular position that can make the projection of the limiting member 10 on the plane smaller than the size of the mounting hole 31, so that the limiting member 10 can pass through the mounting hole 31 at this angular position and reach the back of the thin wall.

[0045] Specifically, at least two sliding grooves 21 opening on the side walls are symmetrically provided on the mounting seat 20. The upper part of the mounting seat 20 forms a flange 22 overlapping the front side of the thin wall at the position of the sliding groove 21. The limiting member 10 moves from the first position to the second position along the sliding groove 21, and when it is in the first position, it is located in the sliding groove 21. When it is in the second position, part of its entity extends out of the sliding groove 21 and toward the back side of the thin wall.

[0046] Specific as Figure 1 and Figure 2As shown, the mounting base 20 is cylindrical in shape as a whole and forms a stepped structure from bottom to top. The diameter of the lower portion is smaller than that of the upper portion, thereby forming a downward step surface at the connection between the two. The diameter of the lower portion of the mounting base 20 is adapted to the diameter of the mounting hole 31, but the diameter of the upper portion is larger than the diameter of the mounting hole 31. Therefore, the lower portion of the mounting base 20 can be inserted into the mounting hole 31, but at the same time, the mounting base 20 will overlap the sink countertop 30 around the mounting hole 31 through the step surface. In particular, two sliding grooves 21 are provided on the mounting base 20. The sliding grooves 21 are opened along the radial direction of the mounting base 20 and are symmetrical to each other. The sliding groove 21 has three side walls, and the part where it connects with the outer wall of the mounting seat 20 forms an opening, and the mounting seat 20 has a flange 22 here. The flange 22 is equivalent to a plate-like structure placed horizontally at the opening of the sliding groove 21. It cooperates with other parts of the mounting seat 20 to form the outer edge of the upper part of the mounting seat 20, and at the same time divides the opening of the sliding groove 21 into two parts, upper and lower.

[0047] After being placed in the sliding groove 21, the limiting member 10 can slide along the sliding groove 21 toward the outside of the mounting seat 20. The limiting member 10 is positioned in the sliding groove 21 as the first position, and then slides toward the outside of the mounting seat 20 to reach the second position. The number of limiting members 10 is the same as the number of sliding grooves 21, with two limiting members 10 provided. In this embodiment, the limiting members 10 are two relatively small block-shaped structures that can freely pass through the mounting hole 31. After passing through the mounting hole 31, they slide from the first position to the second position, with their substantial portions facing the back of the thin wall.

[0048] Of course, in other embodiments, the structure of the limiting member 10 may be different from the above-mentioned embodiments, and it needs to cooperate with the structure of the mounting seat 20 itself. For example, a transversely penetrating groove structure is set in the middle of the mounting seat 20, and the limiting member 10 is a long strip structure, and the limiting member 10 can pass through the mounting hole 31 in an inclined posture and return to the correct position after passing through, so that its two ends can cross the orientation of the mounting hole 31. At the same time, the limiting member 10 can be placed in the groove structure on the mounting seat 20, and then the two ends of the limiting member 10 are abutted against the back of the thin wall, so that the mounting seat 20 can be limited in two vertical directions.

[0049] In this embodiment, the stopper 10 is provided with a mating groove 13. When the stopper 10 is moved to the second position, its two walls are located on one side of the flange 22 and on the back of the thin wall, respectively. The stopper 10 is provided with a screw hole 12. A fastener 14 is screwed into the screw hole 12 and abuts against the flange 22, thereby cooperating between the stopper 10 and the flange 22 to clamp the thin wall. Furthermore, a positioning portion 221 is provided on the flange 22 at a position corresponding to the screw hole 12. The front end of the fastener 14 is terraced or conical, and when it abuts the flange 22, it sinks into the positioning portion 221.

[0050] Specifically, the position limiting member 10 is provided with a groove portion opening in the horizontal direction, which forms the above-mentioned matching groove 13. The two sides of the matching groove 13 have two horizontal sidewall surfaces, and the position limiting member 10 forms these two sidewalls through a physical structure. Figure 3 As an example, the limiting member 10 is provided with a screw hole 12 on the upper side of the matching groove 13. The screw hole 12 passes through the top end surface of the limiting member 10 and a groove wall of the matching groove 13. When the limiting member 10 is located in the sliding groove 21, the limiting member 10 is pushed to move from the first position to the second position. At this time, the flange 22 will enter the matching groove 13, and the sink countertop 30 will also enter the matching groove 13. Figure 4 As shown, at this time, the wall surface on the lower side of the matching groove 13 forms a solid structure facing the back of the sink countertop 30. The wall surface can limit the upward movement of the mounting seat 20 by abutting against the back of the sink countertop 30.

[0051] After the fastener 14 is screwed into the threaded hole 12, its front end extends out of the upper groove wall of the matching groove 13 and abuts against the flange 22. As the fastener 14 is tightened, the limit member 10 will move upward relative to the mounting base 20 until the lower groove wall of the matching groove 13 abuts against the back of the sink countertop 30, thereby completing the fixation of the mounting base 20.

[0052] Of course, in other embodiments, the fastener 14 can be screwed to the mounting base 20. For example, a threaded hole is provided on the flange 22 of the mounting base 20, and the fastener 14 can be screwed into the threaded hole. When the fastener 14 extends out from the lower side of the flange 22, its front end directly abuts against the front surface of the sink countertop 20. At this time, the fastener 14 drives the mounting base 20 to move slightly upward for a distance until the limiting member 10 on the mounting base 20 abuts the back surface of the sink countertop 30. Of course, this requires that the limiting member 10 is constrained on the mounting base 20 and does not tilt, resulting in a situation where it cannot abut against the back surface of the sink countertop 30.

[0053] In addition, in this embodiment, a positioning portion 221 is provided on the flange 22. The positioning portion 221 is a countersunk hole with an inverted trapezoidal cross-section. At the same time, the front end of the fastener 14 can be terraced or conical. When the fastener 14 extends out of the side wall of the mating groove 13, the front end of the fastener 14 will sink into the positioning portion 221, thereby avoiding the position of the fastener 14 from changing and improving the overall stability.

[0054] Furthermore, the size of the limit member 10 is adapted to the width of the sliding groove 21, and a pushing portion is provided on it for pushing the limit member 10 to move along the sliding groove 21. In this embodiment, the limit member 10 is provided with a step portion 11, and the transition surface between the two steps of the step portion 11 forms the above-mentioned pushing portion, and a gap is formed between the pushing portion and the wall of the sliding groove 21 when the limit member 10 is in the first position.

[0055] Specifically, a step portion 11 is provided on the back side of the limit member 10 (relative to the position of the matching groove 13), and the width of the limit member 10 is adapted to the width of the sliding groove 21. When the limit member 10 is placed in the sliding groove 21, it can no longer move in the left and right directions, but can only move forward and backward along the extension direction of the sliding groove 21. In order to facilitate the limit member 10 to be pushed away from the first position by the user when it is in the first position, the transition surface of the step portion 11 forms a pushing portion. This transition surface can form a certain gap with the side wall of the end of the sliding groove 21 when the limit member 10 is in the first position, allowing the user to slide the limit member 10 by using tools or fingernails. Of course, the pushing portion can also be a protruding toggle rod or other structure, as long as it can facilitate the user to push the limit member 10 to the second position.

[0056] like Figure 4 and Figure 5 As shown, when the fastener 14 has not yet been screwed into the screw hole 12, the upper side groove wall of the matching groove 13 of the limiter 10 is against the flange 22. After that, the fastener 14 is screwed into the screw hole 12 and tightened. The upper side groove wall of the matching groove 13 will leave the flange 22, and at the same time, the lower side groove wall of the matching groove 13 will move up until it abuts against the back of the sink countertop 30, thereby cooperating with the flange 22 to clamp the sink countertop 30.

[0057] The installation structure, faucet and sink assembly provided by the present invention utilize the function of the limit member 10 to allow the user to install the faucet from the front of the sink countertop 30, thereby solving the problem of laborious operation of installing the faucet from under the sink.

[0058] The above description and embodiments are intended to explain the scope of protection of the present invention, but do not constitute a limitation thereto. Modifications, equivalent substitutions, or other improvements to the embodiments of the present invention or portions thereof that can be obtained by a person of ordinary skill in the art through logical analysis, reasoning, or limited experimentation based on the teachings of the present invention or the above embodiments, combined with common knowledge, ordinary technical knowledge in the field, and / or prior art, should all be included within the scope of protection of the present invention.
