Description

Technical Field

[0001] The present invention relates to the technical field of mounting and fixing structures, and in particular to a mounting and fixing structure for a faucet, a faucet and a water purifier. Background Art

[0002] The faucet is a common kitchen water facility. In the related art, the bottom of the faucet is generally formed with an external thread. During the installation process, the external thread needs to be passed through the countertop, and a nut is used to tighten the external thread 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 narrow, which is not conducive to the operator's tightening operation, causing inconvenience to the operator when tightening the nut. It is easy for the nut to be not tightened, causing the faucet to loosen during use, and even causing safety hazards such as leakage, which is not conducive to improving user experience. Summary of the invention

[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 installation process in the related art is relatively inconvenient, which easily causes the nut to be not tightened, resulting in the faucet loosening during use, and even causing safety hazards such as leakage, which helps to improve user experience.

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

[0006] A gasket having a threaded hole and an anti-drop hole formed thereon, the threaded hole and the anti-drop hole being able to be placed below the mounting hole of the countertop, and the gasket being abutted against the lower side of the countertop, and the threaded hole being able to be threadedly connected with the external thread of the faucet body;

[0007] A connecting rod is formed with a first convex portion and a second convex portion arranged at intervals. The connecting rod has a first state and a second state. In the first state, the first convex portion can pass through the table top and the anti-drop hole in sequence. In the second state, the second convex portion can abut against the upper side of the table top, and the first convex portion can abut against the lower side of the gasket.

[0008] Beneficial effect: During use of the installation and fixing structure for a faucet of the embodiment of the present invention, the operator can first place the gasket under the countertop, then switch the connecting rod to the first state, so that the first protrusion passes through the limiting hole and the anti-drop hole in sequence and comes to the bottom of the gasket, and then switch the connecting rod to the second state, so that the second protrusion abuts against the countertop above the limiting hole, and the first protrusion abuts against the countertop below the anti-drop hole, thereby hanging the gasket under the countertop with the help of the connecting rod, and making the threaded hole of the gasket below the mounting hole.

[0009] With such a configuration, the operator can pass the external thread of the faucet body through the mounting hole on the countertop and rotate the faucet body above the countertop. The connecting rod can cooperate with the external thread and prevent the gasket from rotating. As the external thread is gradually screwed into the threaded hole, the gasket can move upward along the connecting rod until it is pressed against the lower side of the countertop, thereby completing the installation.

[0010] On this basis, even if the faucet body becomes loose during use, the operator only needs to re-tighten the faucet body above the countertop. Therefore, the installation and fixing structure for the faucet in the embodiment of the present invention is easy to maintain and can facilitate the operator to eliminate the hidden danger of water leakage.

[0011] Therefore, the installation and fixing structure for the faucet in the embodiment of the present invention can install the faucet from above the countertop. Since the space above the countertop is relatively spacious, the convenience of installation operation can be improved, and the faucet can be avoided from being loose due to narrow space, and the faucet can be avoided from being loose due to the faucet not being tightened, causing safety hazards such as leakage, which helps to improve user experience.

[0012] In addition, the above-mentioned installation and fixing structure for the faucet has a simple structure, is easy to assemble, is safe and reliable to use, and is easy to implement and promote.

[0013] In an optional embodiment, the first protrusion and the anti-drop hole have a first size and a second size along the first direction, respectively, the first protrusion and the anti-drop hole have a third size and a fourth size along the second direction, respectively, an angle is formed between the first direction and the second direction, the first size is greater than the third size, the second size is greater than the fourth size, the first size is greater than the fourth size, and is less than or equal to the second size.

[0014] Beneficial effect: That is to say, the size of the long side of the first protrusion is less than or equal to the size of the long side of the anti-drop hole, and larger than the size of the short side of the anti-drop hole. Through such a setting, the operator can rotate the connecting rod around the axis of the connecting rod, thereby driving the connecting rod to switch between the first state and the second state.

[0015] When the long side of the first convex portion matches with the long side of the anti-dropout hole, and the short side of the first convex portion matches with the short side of the anti-dropout hole, the first convex portion can pass through the anti-dropout hole.

[0016] When the long side of the first protrusion matches with the short side of the anti-drop hole, both ends of the long side of the first protrusion can abut against the gasket on both sides of the anti-drop hole.

[0017] In an optional embodiment, a cross-sectional shape of the first protrusion along an axial direction perpendicular to the connecting rod is consistent with a cross-sectional shape of the anti-dropping hole.

[0018] In an optional embodiment, a cross-sectional shape of the first protrusion along an axial direction perpendicular to the connecting rod is consistent with a cross-sectional shape of the limiting hole.

[0019] Beneficial effect: Through such an arrangement, the operator can pass the first protrusion through the limiting hole and the anti-drop hole in sequence without adjusting the connecting rod, thereby facilitating the operator's installation operation.

[0020] In an optional embodiment, the installation and fixing structure also includes a limiting structure, which is provided with a limiting hole. The limiting structure can be arranged above the table top, and the limiting hole is connected to the installation hole. When the connecting rod is in a first state, the first protrusion can pass through the limiting hole. When the connecting rod is in a second state, the second protrusion can be limited to the limiting hole.

[0021] Beneficial effect: Through such an arrangement, the groove wall of the limiting groove can stop the second protrusion from rotating, thereby preventing the connecting rod from rotating with the rotation of the external thread, thereby ensuring that the gasket can be in a horizontal state, so that the external thread can be smoothly screwed into the threaded hole on the gasket.

[0022] In an optional embodiment, a cross section of the limiting groove along an axial direction perpendicular to the connecting rod is consistent with a cross-sectional shape of the second protrusion, and when the first protrusion is in the second state, the second protrusion is limited in the limiting groove.

[0023] Beneficial effect: Through such a setting, the limit groove can limit the second protrusion in an accommodating manner and guide the operator's installation operation at the same time. The operator only needs to place the second protrusion into the limit groove to accurately switch the connecting rod to the second state, avoiding the risk of the gasket falling off due to inappropriate switching.

[0024] In an optional embodiment, the anti-drop holes are arranged in pairs and are arranged on both sides of the threaded hole, and the limiting holes and the anti-drop holes are arranged in one-to-one correspondence.

[0025] Beneficial effect: Through such a setting, during the assembly process, the two connecting rods pass through the anti-drop holes on both sides of the threaded hole and hang the gasket, which can not only effectively ensure that the gasket is in a horizontal state, but also better prevent the gasket from rotating, so that the operator can smoothly screw the external thread into the threaded hole on the gasket.

[0026] In an optional embodiment, the gasket has a fifth dimension along the first direction, the gasket has a sixth dimension along the second direction, and the fifth dimension is greater than the sixth dimension.

[0027] Beneficial effect: Through such an arrangement, during the assembly process, the operator can first pass the smaller side of the gasket through the mounting hole of the table top, thereby placing the gasket under the table top, and then pass the fingers through the mounting hole and threaded hole of the table top and hook the gasket. At this time, the two ends of the long side of the gasket can be against the table top on both sides of the mounting hole.

[0028] 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 inconvenience caused to the installation operation by the narrow space under the table.

[0029] In an optional embodiment, the limiting structure includes a decorative cover, and the decorative cover is provided with an avoidance hole and a limiting hole, and the avoidance hole can allow the external thread of the faucet body to pass through and be threadedly connected with the threaded hole.

[0030] Beneficial effect: Through such an arrangement, the decorative cover can not only be used to limit the connecting rod, but also can be used to cover the connection between the mounting hole and the external thread, thereby improving the aesthetics of the faucet after installation.

[0031] In a second aspect, the present invention further provides a faucet, comprising:

[0032] Faucet body;

[0033] The installation and fixing structure for a faucet according to the first aspect of the present invention is used to install the faucet body on a countertop.

[0034] Beneficial effect: The faucet of the second aspect of the present invention includes or uses the installation and fixing structure for the faucet of the first aspect of the present invention, and thus has its beneficial effect, that is, the faucet of the embodiment of the present invention can install the faucet body from above the countertop. Since the space above the countertop is relatively spacious, the convenience of installation operation can be improved, and the faucet body cannot be tightened due to narrow space, and the faucet body cannot be loosened due to the faucet body not being tightened, causing safety hazards such as leakage, which helps to improve user experience.

[0035] In addition, the faucet has a simple structure, is easy to assemble, and is safe and reliable to use, and is easy to implement, promote, and apply.

[0036] In a third aspect, the present invention further provides a water purifier, comprising the faucet provided in the second aspect of the present invention.

[0037] Beneficial effect: The water purifier of the third aspect of the present invention includes or uses the faucet of the second aspect of the present invention, and thus has its beneficial effect, that is, the water purifier of the embodiment of the present invention can install the faucet body from above the countertop. Since the space above the countertop is relatively spacious, the convenience of installation operation can be improved, and the faucet body can be avoided from being not tightened due to narrow space, and the faucet body can be avoided from being loosened due to the faucet body not being tightened, causing safety hazards such as leakage, which helps to improve user experience.

[0038] In addition, the water purifier has a simple structure, is easy to assemble, and is safe and reliable to use, making it easy to implement, promote, and apply. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0056] Combine the following Figures 1 to 9 , describing an embodiment of the present invention.

[0057] According to an embodiment of the present invention, on the one hand, a mounting and fixing structure for a faucet body is provided, comprising a gasket 1, a limiting structure 3 and a connecting rod 4.

[0058] Among them, the gasket 1 is formed with a threaded hole 101 and an anti-drop hole 102. The threaded hole 101 and the anti-drop hole 102 can be placed below the mounting hole 201 of the countertop 2, and the gasket 1 can be abutted against the lower side of the countertop 2, and the threaded hole 101 can be threadedly connected with the external thread 501 of the faucet body 5. The connecting rod 4 is formed with a first convex portion 401 and a second convex portion 402 arranged at intervals. The connecting rod 4 has a first state and a second state. In the first state, the first convex portion 401 can pass through the countertop 2 and the anti-drop hole 102 in sequence. In the second state, the second convex portion 402 can abut against the upper side of the countertop 2, and the first convex portion 401 can abut against the lower side of the gasket 1.

[0059] During use of the installation and fixing structure for a faucet in an embodiment of the present invention, the operator can first place the gasket 1 under the countertop 2, then switch the connecting rod 4 to the first state, so that the first protrusion 401 passes through the limiting hole 302 and the anti-drop hole 102 in sequence and comes to the bottom of the gasket 1, and then switch the connecting rod 4 to the second state, so that the second protrusion 402 abuts against the countertop 2 above the limiting hole 302, and the first protrusion 401 abuts against the countertop 2 below the anti-drop hole 102, thereby hanging the gasket 1 under the countertop 2 with the help of the connecting rod 4, and making the threaded hole 101 of the gasket 1 below the mounting hole 201.

[0060] By so configuring, the operator can insert the external thread 501 of the faucet body 5 through the mounting hole 201 on the countertop 2 (see FIG. Figure 3 and Figure 4 ), and rotate the faucet body 5 above the countertop 2, the connecting rod 4 can cooperate with the external thread 501 and prevent the gasket 1 from rotating, and as the external thread 501 is gradually screwed into the threaded hole 101, the gasket 1 can move upward along the connecting rod 4 until it is pressed against the lower side of the countertop 2 (see Figure 5 and Figure 6 ) to complete the installation.

[0061] On this basis, even if the faucet body 5 becomes loose during use, the operator only needs to re-tighten the faucet body 5 above the countertop 2. Therefore, the installation and fixing structure for the faucet body of the embodiment of the present invention is easy to maintain and can facilitate the operator to eliminate the hidden danger of water leakage.

[0062] Therefore, the installation and fixing structure for the faucet body of the embodiment of the present invention can install the faucet body 5 from above the countertop 2. Since the space above the countertop 2 is relatively spacious, the convenience of installation operation can be improved, and the faucet body 5 can be avoided from being not tightened due to narrow space, and the faucet 5 can be avoided from being loosened due to the faucet body 5 not being tightened, causing safety hazards such as leakage, which helps to improve user experience.

[0063] In addition, the above-mentioned installation and fixing structure for the faucet 5 is simple in structure, easy to assemble, safe and reliable to use, and easy to implement and promote.

[0064] In a preferred embodiment, the limiting hole 302 is preferably located above the mounting hole 201 .

[0065] In one embodiment, the first protrusion 401 and the anti-drop hole 102 have a first size and a second size along the first direction, respectively, and the first protrusion 401 and the anti-drop hole 102 have a third size and a fourth size along the second direction, respectively. An angle is formed between the first direction and the second direction. The first size is greater than the third size, the second size is greater than the fourth size, and the first size is greater than the fourth size and is less than or equal to the second size.

[0066] That is to say, the dimension of the long side of the first protrusion 401 is less than or equal to the dimension of the long side of the anti-drop hole 102, and greater than the dimension of the short side of the anti-drop hole 102. Through such a setting, the operator can rotate the connecting rod 4 around the axis of the connecting rod 4, thereby driving the connecting rod 4 to switch between the first state and the second state.

[0067] When the long side of the first protrusion 401 matches with the long side of the anti-dropout hole 102 and the short side of the first protrusion 401 matches with the short side of the anti-dropout hole 102 , the first protrusion 401 can pass through the anti-dropout hole 102 .

[0068] When the long side of the first protrusion 401 matches with the short side of the anti-drop hole 102 , both ends of the long side of the first protrusion 401 can abut against the gasket 1 on both sides of the anti-drop hole 102 .

[0069] The first convex portion 401 is preferably, but not limited to, a rectangular convex block, an elliptical convex block, a trapezoidal convex block, a parallelogram convex block or a convex block of other irregular shapes.

[0070] As a changeable implementation, in an embodiment not shown in the drawings, the dimensions of the first protrusion 401 in the first direction and the second direction are consistent. The dimensions of the anti-drop hole 102 in the first direction and the second direction are consistent.

[0071] At this time, the operator can drive the connecting rod 4 to displace the first protrusion 401 from the anti-drop hole 102 , so that the first protrusion 401 abuts against the bottom of the gasket 1 , thereby preventing the gasket 1 from dropping out.

[0072] At this time, the first convex portion 401 is preferably, but not limited to, a square convex portion or a circular convex portion.

[0073] In one embodiment, the cross-sectional shape of the first protrusion 401 along the axial direction perpendicular to the connecting rod 4 is consistent with the cross-sectional shape of the anti-dropping hole 102 .

[0074] As a convertible embodiment, the cross-sectional shape of the anti-drop hole 102 can also be set to be inconsistent with the cross-sectional shape of the anti-drop hole 102, as long as it can satisfy the first state in which the first protrusion can pass through the anti-drop hole 102, and the second state in which it abuts against the hole wall of the anti-drop hole 102 and cannot pass through the anti-drop hole 102.

[0075] In one embodiment, the mounting and fixing structure also includes a limiting structure 3, which is provided with a limiting hole 302. The limiting structure 3 can be arranged above the table top 2, and the limiting hole 302 is connected to the mounting hole 201. When the connecting rod 4 is in the first state, the first protrusion 401 can pass through the limiting hole 302. When the connecting rod 4 is in the second state, the second protrusion 402 can be limited to the limiting hole 302.

[0076] By such arrangement, the limiting structure 3 can limit the second protrusion 402 through the limiting hole 302 to prevent the connecting rod 4 from deflecting when the operator rotates the external thread 501, thereby facilitating the external thread 501 to be smoothly screwed into the threaded hole 101 on the gasket 1.

[0077] As a convertible implementation, in an embodiment not shown in the accompanying drawings, a limiting through hole is formed on the table top 2, and the connecting rod 4 can pass through the limiting through hole, and when the connecting rod 4 is switched to the second state, the second protrusion 402 is abutted against the upper surface of the table top 2.

[0078] In one embodiment, the cross-sectional shape of the first protrusion 401 along the axial direction perpendicular to the connecting rod 4 is consistent with the cross-sectional shape of the limiting hole 302 .

[0079] With such a configuration, the operator does not need to adjust the connecting rod 4 , and can sequentially pass the first protrusion 401 through the limiting hole 302 and the anti-drop hole 102 , thereby facilitating the installation operation of the operator.

[0080] As a convertible implementation, in an embodiment not shown in the accompanying drawings, the cross-sectional shape of the limiting hole 302 can also be set to be inconsistent with the cross-sectional shape of the first protrusion 401, as long as it can be satisfied that the first protrusion 401 can pass through the limiting hole 302 when the connecting rod 4 is in the first state.

[0081] In one embodiment, the mounting and fixing structure further includes a limiting groove 303 . When the connecting rod 4 is in the second state, the second protrusion 402 can be disposed in the limiting groove 303 . A rotation-stopping surface is formed between the groove wall of the limiting groove 303 and the second protrusion 402 .

[0082] By such a configuration, the groove wall of the limiting groove 303 can stop the second protrusion 402 from rotating, thereby preventing the connecting rod 4 from rotating with the rotation of the external thread 501, thereby ensuring that the gasket 1 can be in a horizontal state, so that the external thread 501 can be smoothly screwed into the threaded hole 101 on the gasket 1.

[0083] In one embodiment, the orthographic projections of the first convex portion 401 and the second convex portion 402 toward the plane where the table 2 is located coincide with each other.

[0084] Such an arrangement can facilitate both the processing and the assembly of the connecting rod 4 .

[0085] As a convertible implementation, in an embodiment not shown in the accompanying drawings, the orthographic projections of the first protrusion 401 and the second protrusion 402 toward the plane where the table 2 is located can also be set to be non-overlapping, as long as it can be satisfied that when the connecting rod 4 is in the second state, the second protrusion 402 can be abutted against the upper side of the limiting structure 3, and the first protrusion 401 can be abutted against the lower side of the gasket 1.

[0086] In one embodiment, the cross section of the limiting groove 303 along the axial direction perpendicular to the connecting rod 4 is consistent with the cross-sectional shape of the second protrusion 402 , and when the first protrusion 401 is in the second state, the second protrusion 402 is limited in the limiting groove 303 .

[0087] Through such a configuration, the limiting groove 303 can limit the second protrusion 402 in an accommodating manner and guide the operator's installation operation at the same time. The operator only needs to place the second protrusion 402 into the limiting groove 303 to accurately switch the connecting rod 4 to the second state, avoiding the risk of the gasket 1 falling off due to inappropriate switching.

[0088] In one embodiment, an angle is formed between the length direction of the limiting groove 303 and the limiting opening.

[0089] It should be noted that in the embodiment of the present application, the angle between the limiting groove 303 and the length direction of the limiting hole 302 is not limited. For example, in a preferred embodiment, the length direction of the limiting groove 303 and the length direction of the limiting hole 302 are perpendicular to each other.

[0090] In a preferred embodiment, the limiting groove 303 is also provided with a guide groove section, which is arranged on the side of the limiting groove 303 away from the table top 2. Along the direction approaching the table top 2, the cross-sectional area of ​​the guide groove section gradually decreases. The guide groove section can guide the second protrusion so that the second protrusion can be placed in the limiting groove 303.

[0091] In a preferred embodiment, the anti-drop holes 102 are arranged in pairs and are arranged on both sides of the threaded hole 101 , and the limiting holes 302 are arranged in a one-to-one correspondence with the anti-drop holes 102 .

[0092] Through such an arrangement, during the assembly process, the two connecting rods 4 pass through the anti-drop holes 102 on both sides of the threaded hole 101 and hang the gasket 1, which can not only effectively ensure that the gasket 1 is in a horizontal state, but also better prevent the gasket 1 from rotating, so that the operator can smoothly screw the external thread 501 into the threaded hole 101 on the gasket 1.

[0093] In a preferred embodiment, each pair of anti-drop holes 102 are symmetrically distributed on both sides of the threaded hole 101, and the minimum distance between the two anti-drop holes 102 is consistent with the minimum distance between the two limiting holes 302. Through such a setting, it can be ensured that the gasket 1 remains horizontal after the two connecting rods 4 are inserted, so that the external thread 501 can be smoothly screwed into the threaded hole 101 on the gasket 1.

[0094] As a convertible implementation mode, in an embodiment not shown in the accompanying drawings, the anti-drop hole 102 can also be set to one. In this case, a rotation-stopping surface can be formed between the connecting rod 4 and the anti-dropping hole 102, and the rotation-stopping surface can prevent the gasket 1 from rotating.

[0095] As another convertible implementation, in an embodiment not shown in the accompanying drawings, the anti-drop holes 102 can also be set to more than two and arranged at circumferential intervals along the threaded hole 101, which can also ensure that the gasket 1 is in a horizontal state and prevent the gasket 1 from rotating.

[0096] In a preferred embodiment, the gasket 1 has a fifth dimension along the first direction, the gasket 1 has a sixth dimension along the second direction, and the fifth dimension is greater than the sixth dimension.

[0097] Preferably, the fifth dimension is larger than the diameter of the mounting hole 201 , and the sixth dimension is smaller than the diameter of the mounting hole 201 .

[0098] With such an arrangement, during the assembly process, the operator can first pass the smaller side of the gasket 1 through the mounting hole 201 of the table top 2, thereby placing the gasket 1 under the table top 2, and then pass the fingers through the mounting hole 201 and the threaded hole 101 of the table top 2 and hook the gasket 1. At this time, the two ends of the long side of the gasket 1 can be against the table top 2 on both sides of the mounting hole 201.

[0099] 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 top 2, thereby avoiding the narrow space under the table top 2 and causing inconvenience to the installation operation.

[0100] As an alternative implementation, in an embodiment not shown in the drawings, the dimensions of the gasket 1 along the first direction and the second direction are consistent.

[0101] As another alternative implementation, in an embodiment not shown in the drawings, the dimensions of the gasket 1 in the first direction and the second direction are both larger than the diameter of the mounting hole 201 .

[0102] At this time, the operator can place the gasket 1 from below the table top 2 to the corresponding position of the mounting hole 201. Since the operator does not need to tighten the gasket 1 under the table top 2, the installation operation of the gasket 1 is still relatively simple.

[0103] In a preferred embodiment, the limiting structure 3 is a decorative cover, and the decorative cover is provided with an avoidance hole 301 and a limiting hole 302 . The avoidance hole 301 can allow the external thread 501 of the faucet body 5 to pass through and be threadedly connected with the threaded hole 101 .

[0104] By such arrangement, the decorative cover can not only be used to limit the connection rod 4, but also can be used to cover the connection between the installation hole 201 and the external thread 501, thereby improving the aesthetics of the faucet body 5 after installation.

[0105] According to an embodiment of the present invention, a second aspect further provides a faucet, comprising a faucet body and the mounting and fixing structure for mounting the faucet provided by the first aspect of the present invention.

[0106] The faucet body 5 has an external thread 501, and the external thread 501 is used for threaded connection with the threaded hole 101 of the mounting and fixing structure.

[0107] In one embodiment, a screw is provided at the bottom of the faucet body, an external thread 501 is formed outside the screw, a channel 502 is formed inside the screw, and the channel 502 is connected to the inner tube 503 of the faucet body 5. Through such an arrangement, the screw of the faucet body 5 can not only be used to install the faucet body 5 on the countertop 2, but also can be used for water flow. The structure of the water purifier of the embodiment of the present application is more compact.

[0108] The faucet body 5 is preferably, but not limited to, a gooseneck faucet or the like.
