Technical Field

[0001] The utility model belongs to the technical field of faucet installation, and particularly relates to a faucet installation structure. Background Art

[0002] A faucet is a common name for a water valve, commonly used to control the flow of water and save water. It's often used in conjunction with a sink, installed in kitchens or bathrooms, and used for washing and other purposes. In the prior art, the faucet body is typically mounted on a basin using a base. Specifically, the basin is provided with a mounting hole, the base is mounted in the mounting hole, and is locked to the basin via a locking assembly. The faucet body is then sleeved onto the base and secured with screws.

[0003] Figure 1 Shows an existing faucet installation structure, such as Figure 1 As shown, a through-hole 110 is defined in the lower sidewall of the faucet body 100, and a screw hole 210 is defined in the base 200. When the faucet body 100 is mounted on the base 200, the through-hole 110 corresponds to the screw hole 210, and a fastening screw 300 is inserted through the through-hole 110 and screwed into the screw hole 210, thereby detachably mounting the faucet body 100 on the base 200.

[0042] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0043] Example:

[0044] The faucet installation structure provided in this embodiment is as follows Figure 2-Figure 8 As shown, it includes a mounting base 1, a faucet body 4 and a locking bolt 5, wherein:

[0045] The mounting base 1 is detachably fixed to the basin 3 via a fastening assembly 2, facilitating disassembly and assembly of the mounting base 1 during replacement or maintenance. A horizontal hole 121 is defined on the outer sidewall of the mounting base 1, with the top wall of the horizontal hole 121 being an inclined surface 122. A threaded through-hole 41 is defined on the lower sidewall of the faucet body 4. The bottom end of the faucet body 4 is sleeved onto the outside of the mounting base 1, with the threaded through-hole 41 corresponding to the horizontal hole 121. A locking bolt 5 is threadedly engaged in the threaded through-hole 41. The locking bolt 5 has a head end and a tail end with a nut, with the head end of the locking bolt 5 resting against the inclined surface 122.

[0046] During installation, first install the mounting base 1 on the basin 3 through the fastening assembly 2, then put the faucet body 4 on the above-mentioned mounting base 1, and then insert the locking bolt 5 into the above-mentioned threaded through hole 41, so that the head end of the locking bolt 5 extends into the horizontal hole 121 and presses against the above-mentioned inclined surface 122. As the locking bolt 5 is gradually screwed into the above-mentioned threaded through hole 41, the pressure exerted by the head end of the locking bolt 5 on the above-mentioned inclined surface 122 gradually increases. At the same time, the reaction force exerted by the inclined surface 122 on the bolt will also increase, and the partial reaction force exerted by the inclined surface 122 on the locking bolt 5 will press the locking bolt 5 downward. Because the locking bolt 5 is screwed into the threaded through hole 41 on the faucet body 4, the reaction force exerted by the inclined surface 122 on the locking bolt 5 will drive the faucet body 4 to be pressed downward, so that the faucet body 4 is tightly pressed on the mounting base 1 or the basin 3, thereby making the faucet body 4 more firmly connected to the mounting base 1 or the basin 3.

[0047] Through the above structure, the faucet installation structure provided in this embodiment relies on the cooperation between the locking bolt 5 and the inclined surface 122, so that the faucet body 4 is pressed on the mounting base 1 or the basin 3. When locking, the horizontal hole 121 limits the locking bolt 5 and the inclined surface 122 presses the locking bolt 5, which can effectively prevent the faucet body 4 from loosening after installation.

[0048] Optionally, in this embodiment, the number of horizontal holes 121 provided on the mounting base 1 is multiple, and the number of threaded through holes 41 provided on the faucet body 4 is also multiple. The multiple threaded through holes 41 correspond one-to-one with the multiple horizontal holes 121 to form multiple hole groups, and a locking bolt 5 is installed in each hole group. In this way, the faucet body 4 can be more firmly connected to the mounting base 1 or the basin 3. For example, if 3, 4, 5, 6, or 8 horizontal holes 121 are provided on the mounting base 1, the number of threaded through holes 41 provided on the faucet body 4 is also 3, 4, 5, 6, or 8, respectively.

[0049] Optimally, in this embodiment, the number of the above-mentioned hole groups is two, the horizontal holes 121 in the two hole groups are at the same height, and the horizontal holes 121 in the two hole groups are evenly distributed around the mounting base 1, that is, the number of horizontal holes 121 opened on the mounting base 1 and the number of threaded through holes 41 opened on the faucet body 4 are both two.

[0050] When the locking bolt 5 is pressed against the inclined surface 122, due to the direct contact between the head end of the locking bolt 5 and the inclined surface 122, if the head end of the locking bolt 5 is flat, the friction between it and the inclined surface 122 is very large. When the locking bolt 5 is further turned, not only a large torque is required, but also the inclined surface 122 and the head end of the locking bolt 5 are damaged. In order to make it easier to screw the locking bolt 5 into the inclined surface 122 during the pressing process, and also to protect the inclined surface 122, the locking bolt 5 in this embodiment includes a bolt body 51 and a ball 52. The bolt body 51 has a nut at one end, forming the tail end of the locking bolt 5, and a spherical recess is formed on the other end surface of the bolt body 51. The ball 52 is rotatably mounted in the spherical recess, with a portion of the ball 52 extending out of the spherical recess and forming the head end of the locking bolt 5. In this way, the head end of the locking bolt 5 is a bolt that can rotate on the bolt body 51 .

[0051] Optionally, the ball 52 in this embodiment is a stainless steel ball. When assembling the locking bolt 5, the bolt body 51 can be heated to expand the opening of the spherical recess, thereby inserting the ball 52 into the spherical recess. After cooling, the ball 52 can be rotatably placed in the spherical recess. Of course, other methods can also be used to install the ball 52 into the spherical recess, such as using a ball-point pen installation method similar to the prior art.

[0052] In this way, the part where the locking bolt 5 contacts the inclined surface 122 is the above-mentioned rotatable ball 52. The contact area between the ball 52 and the inclined surface 122 is smaller, and the ball 52 can rotate. Therefore, when the head end of the locking bolt 5 is pressed on the inclined surface 122, only a small force is needed to continue to twist the locking bolt 5 and continue to screw it in. When the faucet body is pressed against the basin 3 or the mounting base 1, the ball 52 is also pressed against the above-mentioned inclined surface 122, thereby achieving a locking effect.

[0053] Optionally, in this embodiment, a thickened portion is provided on the outer wall of the faucet body 4, corresponding to the threaded through-hole 41, and the threaded through-hole 41 extends through the thickened portion. This allows for a greater number of thread turns within the threaded through-hole 41, allowing the locking bolt 5 to be threaded more times within the threaded through-hole 41. This not only provides a better preload force but also ensures a more secure connection between the locking bolt 5 and the faucet body 4. Specifically, the thickened portion is a raised ring 42 that surrounds the faucet body 4 and is integrally formed with the faucet body 4.

[0054] An alternative embodiment of this embodiment is as follows: The mounting base 1 includes an annular plate 11, an upper convex tube 12, and a lower convex tube 13. The upper convex tube 12 and the lower convex tube 13 are integrally formed on the upper and lower side surfaces of the annular plate 11, respectively. The annular plate 11, the upper convex tube 12, and the lower convex tube 13 are coaxially arranged. The annular plate 11 is connected to the basin 3 via a fastening assembly 2. A mounting hole 31 is defined in the basin 3, and the lower convex tube 13 is inserted into the mounting hole 31 for positioning. It should be noted that the lower convex tube 13 does not extend out of the mounting hole 31. The annular plate 11 overlaps the basin 3, and the upper convex tube 12 is positioned above the basin 3. A slot 43 is defined at the bottom end of the faucet body 4. A threaded through hole 41 is defined in the side wall of the slot 43. The upper convex tube 12 is inserted into the slot 43, thereby allowing the bottom end of the faucet body 4 to be sheathed outside the mounting base 1. A horizontal hole 121 is defined in the outer wall of the upper convex tube 12. Optionally, in this embodiment, a thickening protrusion corresponding to the horizontal hole 121 may be provided on the inner wall of the upper convex tube 12; of course, if the wall of the upper convex tube 12 is thick enough, the thickening protrusion may not be provided.

[0055] In this case, in this embodiment, the bottom end of the faucet body 4 is in close contact with the top surface of the annular plate 11 , that is, when the faucet body 4 is pressed, it is pressed against the annular plate 11 .

[0056] In order to prevent the locking bolt 5 from leaking out, thereby protecting the locking bolt 5, and also to make the outer tube of the entire faucet installation structure more beautiful, in this embodiment, a protective cover is mounted on the faucet body, and the protective cover is screwed to the annular plate 11, that is, the outer ring wall of the annular plate 11 is provided with an external thread, and the protective cover is provided with an internal thread. With the help of the cooperation between the internal thread and the external thread, the protective cover is screwed to the annular plate 11, and the protective cover is provided outside the locking bolt 5, and the protective cover at this time is also provided outside the thickened portion.

[0057] Optionally, the fastening assembly 2 in this embodiment includes a connecting bolt 21 and a locking block 22, wherein:

[0058] The inner wall of the upper convex tube 12 is provided with a boss 111, which has a through-hole into which the connecting bolt 21 is inserted. A locking block 22 is provided with a threaded through-hole. This is larger than the mounting hole 31 on the basin 3 and is positioned below the basin 3. The connecting bolt 21 is threaded into the through-hole. When the connecting bolt 21 is tightened, the locking block 22 and the annular plate 11 clamp the basin 3.

[0059] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
