Description

Technical Field

[0001] The utility model relates to the technical field of installation and fixing structures, and in particular to an installation and fixing structure for a faucet, a faucet and a water purifier. Background Art

[0002] The faucet is a common kitchen water facility. In related technologies, a screw is generally formed at the bottom of the faucet. During the installation process, the screw needs to be passed through the countertop and a nut is tightened on the screw under the countertop to fix the faucet on the countertop.

[0003] However, since the faucet is usually installed in the corner of the kitchen sink, the space under the countertop is relatively small, which is not conducive to the operator's tightening operation, causing great inconvenience to the operator when tightening the nut. The faucet is inconvenient to disassemble and maintain, which is not conducive to improving the user experience. Utility Model Content

[0004] In view of this, the present invention provides an installation and fixing structure for a faucet, a faucet and a water purifier to solve the problem that the faucet in the related art is difficult to disassemble and assemble, which helps to improve the user experience.

[0005] In a first aspect, the utility model provides a mounting and fixing structure for a faucet, comprising:

[0006] A mounting base is used to be connected to the table top, and one of a limiting groove and a protrusion is formed on the mounting base;

[0007] A fixing ring is used to connect to the faucet body, and the fixing ring is formed with the other of a limiting groove and a protrusion;

[0008] The limiting groove includes an inlet and an anti-slip structure. The inlet allows the convex part to enter the limiting groove. The anti-slip structure is arranged at the inlet of the limiting groove and has a locking state for blocking the inlet and an avoidance state for exposing the inlet.

[0009] Beneficial effect: During use of the installation and fixing structure of the embodiment of the utility model, the operator can first connect the mounting seat to the countertop, connect the fixing ring to the faucet body, and then switch the anti-slip structure to the avoidance state, so that the protrusion enters the limiting groove, and then switch the anti-slip structure to the locking state, thereby limiting the protrusion in the limiting groove, thereby realizing the connection between the fixing ring and the mounting seat, and then fixing the faucet body to the countertop.

[0010] When the faucet body needs to be maintained or replaced, the operator can switch the anti-detachment structure to the avoidance state, thereby removing the protrusion from the limiting groove, and then releasing the connection between the protrusion and the limiting groove, so that the faucet body can be easily and quickly removed from the countertop.

[0011] Therefore, the installation and fixing structure of the embodiment of the present invention can simplify the operation of disassembling and assembling the faucet body, thereby making it easier for the operator to repair or replace the faucet body, which helps to improve the user experience.

[0012] In an optional embodiment, the mounting base includes:

[0013] The mounting base body is used to be connected to the table;

[0014] an annular protrusion, provided on the mounting seat body and extending along the circumference of the mounting seat;

[0015] The stop wall connects the annular protrusion and the mounting seat body, and a limiting groove is formed between the mounting seat body, the stop wall and the annular protrusion.

[0016] Beneficial effect: Through such a setting, the operator can align the protrusion of the fixing ring with the inlet of the limiting groove of the mounting seat, and then rotate the faucet body so that the protrusion can rotate along the circumference of the mounting seat and enter the limiting groove. The stop wall can prevent the protrusion from continuing to move when it abuts against the protrusion.

[0017] After the installation is completed, the limiting wall can cooperate with the anti-slip structure to limit the protrusion along the circumference of the mounting seat. The annular protrusion can cooperate with the mounting seat body and limit the protrusion along the vertical direction, thereby preventing the faucet body from shaking after installation.

[0018] In an optional embodiment, the mounting base further comprises:

[0019] A first avoidance opening is formed on the mounting base body and can allow a water pipe of the faucet body to pass through;

[0020] The annular wall is arranged on the mounting seat body and surrounds the first avoidance opening. The annular convex portion is arranged on the outer periphery of the annular wall, and the convex portion is arranged on the inner periphery of the fixing ring.

[0021] Beneficial effect: Through such an arrangement, after the faucet body is assembled, the fixing ring can be arranged around the outer periphery of the ring wall and cover the connection between the limiting groove and the protrusion, thereby helping to improve the aesthetics of the faucet body.

[0022] In an optional embodiment, a notch is formed on the mounting seat body, and the anti-slip structure includes:

[0023] An elastic arm is disposed in the notch, a first end of the elastic arm is connected to the mounting seat body, and a second end of the elastic arm extends to the inlet of the limiting groove;

[0024] The anti-slip convex portion is arranged at the inlet of the limiting groove and is connected to the second end of the elastic arm.

[0025] Beneficial effect: Through such a setting, when the fixing ring needs to be connected to the mounting seat, the operator can compress the anti-slip protrusion so that the elastic arm moves in a direction away from the annular protrusion, thereby switching the anti-slip structure to an avoidance state exposing the introduction port, thereby allowing the protrusion to enter the limiting groove through the introduction port.

[0026] After the convex portion enters the limiting groove, the anti-slip structure loses the external force, and the anti-slip convex portion enters the inlet of the limiting groove, thereby locking the convex portion in the limiting groove.

[0027] In an optional embodiment, a leading-in slope is provided on a side of the anti-slip protrusion away from the stop wall, and the distance between the leading-in slope and the annular protrusion gradually decreases in a direction approaching the stop wall.

[0028] Beneficial effect: Through such a setting, when the fixing ring needs to be connected to the mounting seat, the operator can directly place the protrusion at the inlet of the limiting groove and rotate the fixing ring. The protrusion can cooperate with the inlet inclined surface and drive the anti-slip protrusion to move downward, thereby exposing the inlet so that the protrusion can enter the limiting groove.

[0029] In an optional embodiment, an anti-slip surface is provided on the side of the anti-slip protrusion facing the stop wall, and the anti-slip surface can abut against the protrusion and prevent the protrusion from escaping from the limiting groove.

[0030] In an optional embodiment, the mounting and fixing structure also includes an unlocking ring, which is rotatably mounted on the mounting seat. The unlocking ring has a locking position and an unlocking position. When the unlocking ring is in the locking position, the anti-slip structure can be switched to a locking state. When the unlocking ring is in the unlocking position, the anti-slip structure can be switched to an avoidance state.

[0031] Beneficial effect: Through such a setting, when installing the faucet body on the countertop, the operator can put the unlocking ring on the mounting seat and put the unlocking ring in the locked position, then align the protrusion of the fixing ring with the inlet of the limiting groove, rotate the faucet body, and make the protrusion enter the limiting groove.

[0032] When the faucet body needs to be removed from the countertop, the operator can switch the unlocking ring to the unlocking position, thereby compressing the anti-drop protrusion and exposing the avoidance opening, and then rotate the protrusion out of the limit groove through the guide opening, thereby releasing the connection between the fixing ring and the mounting base.

[0033] On this basis, the unlocking ring can also be used to cover the connection between the fixing ring and the mounting seat, thereby helping to improve the aesthetics of the mounting and fixing structure.

[0034] In an optional embodiment, the unlocking loop includes:

[0035] The annular body has a notch formed on its inner circumference. When the unlocking ring is in the locked position, the anti-slip structure can pass through the notch. When the unlocking ring is in the unlocked position, the side wall of the notch can abut against the anti-slip structure and drive the anti-slip protrusion to move in a direction away from the limiting groove.

[0036] In an optional embodiment, the mounting and fixing structure further comprises:

[0037] The gasket is used to abut against the lower side of the countertop. The gasket is provided with a second avoidance opening and a first connecting hole. The second avoidance opening is used for the water pipe of the faucet body to pass through. The mounting base is correspondingly provided with a second connecting hole. The second connecting hole and the first connecting hole can allow fasteners to pass through and connect the mounting base and the gasket.

[0038] Beneficial effect: The operator can use fasteners to connect the gasket and the mounting base, thereby fixing the mounting base on the table.

[0039] In an optional embodiment, the second connecting hole is a threaded hole, and the fastener is a bolt.

[0040] Beneficial effect: Through such a setting, during the installation process, the operator can press the gasket against the lower side of the table top, and then rotate the bolt above the table top to complete the connection between the mounting base and the gasket. During the installation process, there is no need to tighten the nut under the table top, which can avoid the inconvenience of the installation process of the mounting base caused by the narrow space under the table top.

[0041] In an optional embodiment, the gasket has a first size along the first direction and a second size along the second direction, the first size is greater than the second size, and an angle is formed between the first direction and the second direction.

[0042] Beneficial effect: Through such a setting, the operator can first pass the smaller side of the gasket through the mounting hole on the table, thereby placing the gasket under the table, and then use his fingers to pass through the mounting hole of the table and the second avoidance hole on the gasket in turn, and hook the gasket with his fingers.

[0043] Therefore, during the installation process of the installation and fixing structure of the embodiment of the present invention, the operator does not need to operate under the table, thereby avoiding the narrow space under the table and causing inconvenience to the installation operation.

[0044] In a second aspect, the present invention further provides a faucet, comprising:

[0045] Faucet body;

[0046] The installation and fixing structure of the first aspect of the present invention is used to install a faucet body on a countertop.

[0047] Beneficial effect: The faucet of the second aspect of the utility model includes or uses the installation and fixing structure of the first aspect of the utility model, and thus has its beneficial effect, namely, it can simplify the operation of disassembling and assembling the faucet body, thereby facilitating the operator to repair or replace the faucet body, and helping to improve the user experience.

[0070] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0071] The following combination Figures 1 to 11 , describing the embodiments of the present utility model.

[0072] According to an embodiment of the present invention, on one hand, a mounting and fixing structure for a faucet is provided, comprising a mounting seat 1 , a fixing ring 2 and a limiting groove 11 .

[0073] The mounting base 1 is configured to be connected to the countertop 6 and is formed with either a limiting groove 11 or a protrusion 21. The fixing ring 2 is configured to be connected to the faucet body 5 and is formed with the other of the limiting groove 11 and the protrusion 21. The limiting groove 11 includes an inlet 111 and an anti-slip structure 113. The inlet 111 allows the protrusion 21 to enter the limiting groove 11. The anti-slip structure 113 is located at the inlet 111 of the limiting groove 11 and has a locking state, blocking the inlet 111, and a retracting state, exposing the inlet 111.

[0074] During use of the installation and fixing structure of the embodiment of the present invention, the operator can first connect the mounting base 1 to the countertop 6, connect the fixing ring 2 to the faucet body 5, and then switch the anti-slip structure 113 to the avoidance state, so that the protrusion 21 enters the limiting groove 11, and then switch the anti-slip structure 113 to the locking state, thereby limiting the protrusion 21 to the limiting groove 11, thereby realizing the connection between the fixing ring 2 and the mounting base 1, and then fixing the faucet body 5 on the countertop 6.

[0075] When the faucet body 5 needs to be maintained or replaced, the operator can switch the anti-detachment structure 113 to the avoidance state, thereby removing the protrusion 21 from the limiting groove 11, and then releasing the connection between the protrusion 21 and the limiting groove 11, so that the faucet body 5 can be easily and quickly removed from the countertop 6.

[0076] Therefore, the installation and fixing structure of the embodiment of the present invention can simplify the operation of disassembling and assembling the faucet body 5, thereby making it easier for the operator to repair or replace the faucet body 5, and helping to improve the user experience.

[0077] The connection between the mounting base 1 and the table top 6 is preferably a fixed connection, which can be, for example, a bolt 7 connection, riveting, or bonding.

[0078] The connection between the fixing ring 2 and the faucet body 5 is preferably a fixed connection. For example, in a preferred embodiment, the bottom of the faucet body 5 is provided with an internal thread, and the outer periphery of the fixing ring 2 is provided with an external thread. The operator can apply glue on the external thread and then connect the fixing ring 2 to the bottom thread of the faucet body 5. After the glue solidifies, the connection between the fixing ring 2 and the faucet body 5 is not easy to loosen.

[0079] In one embodiment, Figure 4 As shown, the mounting seat 1 includes a mounting seat body 12 , an annular protrusion 13 and a stop wall 112 .

[0080] The mounting base body 12 is configured to be connected to the tabletop 6. An annular protrusion 13 is provided on the mounting base body 12 and extends circumferentially around the mounting base 1. A retaining groove 11 is formed between the annular protrusion 13 and the mounting base body 12, the retaining wall 112, and the annular protrusion 13. A protrusion 21 is formed on the retaining ring 2.

[0081] By such a configuration, the operator can align the protrusion 21 of the fixing ring 2 with the inlet 111 of the limiting groove 11 of the mounting seat 1, and then rotate the faucet body 5 so that the protrusion 21 can rotate along the circumference of the mounting seat 1 and enter the limiting groove 11. The stop wall 112 can prevent the protrusion 21 from continuing to move when it abuts against the protrusion 21.

[0082] After the installation is completed, the limiting wall can cooperate with the anti-slip structure 113 to limit the protrusion 21 along the circumference of the mounting seat 1, and the annular protrusion 13 can cooperate with the mounting seat body 12 to limit the protrusion 21 along the vertical direction, thereby preventing the faucet body 5 from shaking after installation.

[0083] It should be noted that if Figure 4 and Figure 5 As shown, in the embodiment of the present application, the number of annular protrusions 13 and protrusions 21 is not limited. For example, in a preferred embodiment, the mounting base body 12 is provided with two annular protrusions 13, and the two annular protrusions 13 are centrally symmetrical. The fixing ring 2 is provided with two protrusions 21, and the two protrusions 21 are centrally symmetrical. This arrangement can prevent the faucet body 5 from tilting during installation.

[0084] As a convertible embodiment, the limiting groove 11 can also be set to extend in the vertical direction, or be set at an angle.

[0085] As another alternative embodiment, the protrusion 21 may be optionally formed on the mounting seat body 12 , and the limiting groove 11 may be optionally formed on the fixing ring 2 .

[0086] In one embodiment, the mounting seat 1 further includes a first avoidance opening 14 and an annular wall 15 .

[0087] A first escape opening 14 is formed on the mounting base body 12, allowing the water pipe of the faucet body 5 to pass through. An annular wall 15 is provided on the mounting base body 12 and surrounds the first escape opening 14. The annular protrusion 13 is provided on the outer periphery of the annular wall 15, and the protrusion 21 is provided on the inner periphery of the fixing ring 2.

[0088] With such an arrangement, after the faucet body 5 is assembled, the fixing ring 2 can be arranged around the outer periphery of the ring wall 15 and cover the connection between the limiting groove 11 and the protrusion 21, thereby helping to improve the aesthetics of the faucet body 5.

[0089] As a convertible embodiment, the protrusion 21 is formed on the outer periphery of the fixing ring 2 , and the limiting groove 11 is formed on the inner periphery of the annular wall 15 of the mounting seat 1 .

[0090] In one embodiment, a notch 1131 is formed in the mounting base body 12. The anti-slip structure 113 includes an elastic arm 1132 and an anti-slip protrusion 1133. The elastic arm 1132 is disposed within the notch 1131. The first end of the elastic arm 1132 is connected to the mounting base body 12, and the second end extends to the inlet 111 of the retaining groove 11. The anti-slip protrusion 1133 is disposed at the inlet 111 of the retaining groove 11 and is connected to the second end of the elastic arm 1132.

[0091] By such a setting, when it is necessary to connect the fixing ring 2 to the mounting seat 1, the operator can compress the anti-slip protrusion 1133 so that the elastic arm 1132 moves in a direction away from the annular protrusion, thereby switching the anti-slip structure 113 to an avoidance state exposing the introduction port 111, thereby allowing the protrusion 21 to enter the limiting groove 11 through the introduction port 111.

[0092] When the protrusion 21 enters the limiting groove 11 , the anti-slip structure 113 loses the external force, and the anti-slip protrusion 1133 enters the inlet 111 of the limiting groove 11 , thereby locking the protrusion 21 in the limiting groove 11 .

[0093] In one embodiment, a leading slope 11331 is provided on a side of the anti-slip protrusion 1133 away from the stop wall 112 , and the distance between the leading slope 11331 and the annular protrusion 13 gradually decreases in a direction approaching the stop wall 112 .

[0094] Through such an arrangement, when the fixing ring 2 needs to be connected to the mounting seat 1, the operator can directly place the protrusion 21 at the inlet 111 of the limiting groove 11 and rotate the fixing ring 2. The protrusion 21 can cooperate with the inlet slope 11331 and drive the anti-slip protrusion 1133 to move downward, thereby exposing the inlet 111 to facilitate the protrusion 21 to enter the limiting groove 11.

[0095] As a convertible embodiment, the operator may also choose to directly press the anti-dropout protrusion 1133 and insert the protrusion 21 into the inlet 111, and then rotate the fixing ring 2 toward the stop wall 112 to complete the installation operation of the faucet body 5.

[0096] In one embodiment, a guide surface is formed at one end of the protrusion 21, and the guide surface is formed on the upper side of the protrusion 21. The guide surface is inclined downward in the direction of the protrusion 21 entering the limiting groove 11. The annular protrusion 13 is provided with a mating surface at the inlet 111. The mating surface is inclined downward in the direction of the protrusion 21 entering the limiting groove 11. The guide surface can match with the mating surface, thereby facilitating the protrusion 21 to enter the limiting groove 11.

[0097] In one embodiment, a side of the anti-slip protrusion 1133 facing the stop wall 112 is provided with an anti-slip surface 11332 , and the anti-slip surface 11332 can abut against the protrusion 21 and prevent the protrusion 21 from escaping from the limiting groove 11 .

[0098] The anti-slip surface 11332 can be selected to extend in the vertical direction, or it can be selected to be inclined from bottom to top toward the stop wall 112. By such a setting, it can be ensured that when the protrusion 21 is against the anti-slip surface 11332, the anti-slip surface 11332 will not tend to move downward under the pressure of the protrusion 21.

[0099] In one embodiment, Figure 6 As shown, the mounting and fixing structure also includes an unlocking ring 3, which is rotatably mounted on the mounting seat 1. The unlocking ring 3 has a locking position and an unlocking position. When the unlocking ring 3 is in the locking position, the anti-slip structure 113 can be switched to the locking state. When the unlocking ring 3 is in the unlocking position, the anti-slip structure 113 can be switched to the avoidance state.

[0100] With such an arrangement, when installing the faucet body 5 on the countertop 6, the operator can put the unlocking ring 3 on the mounting seat 1 and put the unlocking ring 3 in the locked position, then align the protrusion 21 of the fixing ring 2 with the inlet 111 of the limiting groove 11, and rotate the faucet body 5 so that the protrusion 21 enters the limiting groove 11.

[0101] When the faucet body 5 needs to be removed from the countertop 6, the operator can switch the unlocking ring 3 to the unlocking position, thereby compressing the anti-slip protrusion 1133 and exposing the avoidance opening, and then unscrew the protrusion 21 out of the limiting groove 11 through the inlet 111, thereby releasing the connection between the fixing ring 2 and the mounting base 1.

[0102] On this basis, the unlocking ring 3 can also be used to cover the connection between the fixing ring 2 and the mounting seat 1, thereby helping to improve the aesthetics of the mounting and fixing structure.

[0103] As a switchable embodiment, the state of the anti-slip structure 113 is switched by the operator manually pressing. When the operator presses the anti-slip protrusion 1133, the anti-slip structure 113 can be switched to the avoidance state. When the operator's finger releases the anti-slip protrusion 1133, the anti-slip structure 113 can return to the locked state due to its own elastic restoring force.

[0104] In one embodiment, the unlocking ring 3 includes an annular body 31. A notch 32 is formed on the inner circumference of the annular body 31. Figure 8 and Figure 9 As shown, when the unlocking ring 3 is in the locked position, the anti-slip structure 113 can pass through the notch 32, as shown in FIG. Figure 10 and Figure 11 As shown, when the unlocking ring 3 is in the unlocking position, the side wall of the notch 32 can abut against and compress the anti-slip structure 113 .

[0105] In one embodiment, Figure 7 As shown, the mounting and fixing structure further includes a gasket 4. The gasket 4 is used to abut against the underside of the countertop 6. The gasket 4 is provided with a second avoidance opening 41 and a first connection hole 42. The second avoidance opening 41 is used to allow the water pipe of the faucet body 5 to pass through. The mounting base 1 is correspondingly provided with a second connection hole 16. The second connection hole 16 and the first connection hole 42 can allow fasteners to pass through and connect the mounting base 1 and the gasket 4.

[0106] The operator can use fasteners to connect the gasket 4 and the mounting base 1 , thereby fixing the mounting base 1 on the table 6 .

[0107] As an alternative embodiment, the mounting base 1 is directly connected to the table top 6 via fasteners.

[0108] In one embodiment, the second connection hole 16 is a threaded hole, and the fastener is a bolt 7 .

[0109] Through such an arrangement, during the installation process, the operator can press the gasket 4 against the lower side of the table 6, and then rotate the bolt 7 above the table 6 to complete the connection between the mounting base 1 and the gasket 4. During the installation process, there is no need to tighten the nut below the table 6, which can avoid the inconvenience of the installation process of the mounting base 1 caused by the narrow space below the table 6.

[0110] It should be noted that in the embodiment of the present application, the number of the second connection holes 16 is not limited. Schematically, in an optional embodiment, there are two second connection holes 16, which are respectively provided on both sides of the second avoidance opening 41. The first connection holes 42 are provided in a one-to-one correspondence with the second connection holes 16.

[0111] With such an arrangement, during the installation process, the operator can first insert a bolt 7 through the second connecting hole 16 and the first connecting hole 42 in sequence. At this time, the operator can lift the gasket 4 by one bolt 7, and use another bolt 7 to insert it through another group of second connecting holes 16 and the first connecting hole 42 in sequence, and tighten the two bolts 7 respectively until the gasket 4 and the mounting base 1 are respectively pressed against both sides of the table 6.

[0112] In one embodiment, the gasket 4 has a first size along the first direction and a second size along the second direction, the first size is greater than the second size, and an angle is formed between the first direction and the second direction.

[0113] Preferably, the first dimension is larger than the diameter of the mounting hole on the table 6, and the second dimension is smaller than the diameter of the mounting hole on the table 6. By such an arrangement, the operator can first pass the smaller side of the gasket 4 through the mounting hole on the table 6, thereby placing the gasket 4 under the table 6, and then pass the fingers through the mounting hole of the table 6 and the second avoidance opening 41 on the gasket 4 in turn, and hook the gasket 4 with the fingers.

[0114] Therefore, during the installation process of the installation and fixing structure of the embodiment of the present invention, the operator does not need to operate under the table 6, thereby avoiding the narrow space under the table 6 and causing inconvenience to the installation operation.

[0115] As an alternative implementation, in an embodiment not shown in the drawings, the dimensions of the spacer 4 along the first direction and the second direction are consistent.

[0116] As another alternative implementation, in an embodiment not shown in the drawings, the dimensions of the gasket 4 in the first direction and the second direction are both larger than the diameter of the mounting hole.

[0117] At this time, the operator can place the gasket 4 from the bottom of the table 6 to the corresponding position of the installation hole. Since the operator does not need to tighten the gasket 4 under the table 6, the installation operation of the gasket 4 is still relatively simple.
