Description

Technical Field

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

[0002] A faucet is a common kitchen water facility. In the related art, an external thread is generally formed at the bottom of the faucet. During the installation process, the external thread needs to pass through the tabletop, and a nut is used to tighten the external thread below the tabletop, so as to fix the faucet on the tabletop.

[0003] However, since the faucet is usually installed at the corner of the kitchen sink, the space under the tabletop is relatively narrow, which is not conducive to the tightening operation of the operator. It is very inconvenient for the operator to tighten the nut, and it is easy to cause the nut not to be tightened, resulting in the faucet loosening during use, and even causing safety hazards such as water leakage, which is not conducive to improving the user experience. Summary of the Utility Model

[0004] In view of this, the utility model provides an installation and fixing structure for a faucet, a faucet and a water purifier to solve the problems in the related art that the installation process of the faucet is relatively inconvenient, it is easy to cause the nut not to be tightened, resulting in the faucet loosening during use, and even causing safety hazards such as water leakage, which helps to improve the user experience.

[0005] In the first aspect, the utility model provides an installation and fixing structure for a faucet, including:

[0006] A gasket, on which a threaded hole and an anti-detachment hole are formed. The threaded hole and the anti-detachment hole can be placed below the installation hole of the tabletop, and the gasket abuts against the lower side of the tabletop. The threaded hole can be threadedly connected with the external thread of the faucet body;

[0007] A connecting rod, on which a first convex part and a second convex part are formed at intervals. The connecting rod has a first state and a second state. In the first state, the first convex part can sequentially pass through the tabletop and the anti-detachment hole. In the second state, the second convex part can abut against the upper side of the tabletop, and the first convex part can abut against the lower side of the gasket.

[0008] Beneficial effects: During the use of the installation and fixing structure for a faucet according to the embodiment of the utility model, the operator can first place the gasket below the tabletop, then switch the connecting rod to the first state, so that the first convex part sequentially passes through the limiting hole and the anti-detachment hole and comes below the gasket, and then switch the connecting rod to the second state, so that the second convex part abuts against the tabletop above the limiting hole, and the first convex part abuts against the tabletop below the anti-detachment hole, thereby hanging the gasket below the tabletop by means of the connecting rod and making the threaded hole of the gasket located below the installation hole.

[0009] By setting it like this, the operator can pass the external thread of the faucet body through the mounting hole on the tabletop, and rotate the faucet body above the tabletop. 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 tabletop, thus completing the installation.

[0010] On this basis, even if the faucet body becomes loose during use, the operator only needs to tighten the faucet body again above the tabletop. Therefore, the installation and fixing structure for the faucet in the embodiment of the present utility model is convenient 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 utility model can install the faucet from above the tabletop. Since the space above the tabletop is relatively spacious, it can improve the convenience of the installation operation, avoid the faucet not being tightened due to narrow space, and avoid problems such as the faucet becoming loose and causing water leakage and other potential safety hazards caused by the faucet not being tightened, which helps to improve the 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 in use, and is convenient for implementation, popularization and application.

[0013] In an alternative embodiment, the first convex portion and the anti - detachment hole respectively have a first dimension and a second dimension along a first direction, and the first convex portion and the anti - detachment hole respectively have a third dimension and a fourth dimension along a second direction. An angle is formed between the first direction and the second direction. The first dimension is greater than the third dimension, the second dimension is greater than the fourth dimension, the first dimension is greater than the fourth dimension, and is less than or equal to the second dimension.

[0014] Beneficial effect: That is to say, the dimension of the long side of the first convex portion is less than or equal to the dimension of the long side of the anti - detachment hole and greater than the dimension of the short side of the anti - detachment hole. By setting it like this, the operator can rotate the connecting rod around the axis of the connecting rod, so as to switch the driving connecting rod between the first state and the second state.

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

[0016] When the long side of the first convex portion cooperates with the short side of the anti - detachment hole, both ends of the long side of the first convex portion can abut against the gasket on both sides of the anti - detachment hole.

[0017] In an alternative embodiment, the cross - sectional shape of the first convex portion along the direction perpendicular to the axial direction of the connecting rod is the same as the cross - sectional shape of the anti - detachment hole.

[0018] In an alternative embodiment, the cross-sectional shape of the first convex portion in a direction perpendicular to the axial direction of the connecting rod is the same as the cross-sectional shape of the limiting hole.

[0019] Advantageous effects: By setting it in this way, the operator can pass the first convex portion through the limiting hole and the anti-detachment hole in sequence without adjusting the connecting rod, thus facilitating the installation operation of the operator.

[0020] In an alternative embodiment, the installation and fixing structure further includes a limiting structure provided with a limiting hole. The limiting structure can be disposed above the tabletop, and the limiting hole communicates with the installation hole. When the connecting rod is in the first state, the first convex portion can pass through the limiting hole. When the connecting rod is in the second state, the second convex portion can be limited in the limiting hole.

[0021] Advantageous effects: By setting it in this way, the groove wall of the limiting groove can stop the rotation of the second convex portion, thereby preventing the connecting rod from rotating with the rotation of the external thread, and further ensuring that the gasket can be in a horizontal state, so as to facilitate the smooth screwing of the external thread into the threaded hole on the gasket.

[0022] In an alternative embodiment, the cross-section of the limiting groove in a direction perpendicular to the axial direction of the connecting rod is the same as the cross-sectional shape of the second convex portion. When the first convex portion is in the second state, the second convex portion is limited in the limiting groove.

[0023] Advantageous effects: By setting it in this way, the limiting groove can limit the second convex portion in an accommodating manner and at the same time guide the installation operation of the operator. The operator only needs to put the second convex portion into the limiting groove to accurately switch the connecting rod to the second state, avoiding the risk of the gasket falling due to improper switching.

[0024] In an alternative embodiment, the anti-detachment holes are provided in pairs and are respectively arranged on both sides of the threaded hole, and the limiting holes are arranged in one-to-one correspondence with the anti-detachment holes.

[0025] Advantageous effects: By setting it in this way, during the assembly process, the two connecting rods pass through the anti-detachment holes on both sides of the threaded hole and hang on the gasket respectively, which can not only effectively ensure that the gasket is in a horizontal state, but also better prevent the gasket from rotating, so as to facilitate the operator to screw the external thread into the threaded hole on the gasket smoothly.

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

[0027] Beneficial effects: By setting it like this, during the assembly process, the operator can first pass the smaller side of the gasket through the mounting hole of the tabletop, thereby placing the gasket below the tabletop. Then, insert a finger through the mounting hole and the threaded hole of the tabletop and hook the gasket. At this time, both ends of the long side of the gasket can abut against the tabletop 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 utility model, the operator does not need to operate below the tabletop, thus avoiding the narrow space below the tabletop and causing inconvenience to the installation operation.

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

[0030] Beneficial effects: By setting it like this, the decorative cover can not only be used to limit the connecting rod, but also be used to block the connection part between the mounting hole and the external thread, thereby improving the aesthetics of the faucet after installation.

[0031] In a second aspect, the present utility model also provides a faucet, including:

[0032] A faucet body;

[0033] The installation and fixing structure for a faucet described in the first aspect of the present utility model is used to install the faucet body on the tabletop.

[0034] Beneficial effects: The faucet in the second aspect of the present utility model includes or uses the installation and fixing structure for a faucet in the first aspect of the present utility model, so it has its beneficial effects. That is, the faucet of the embodiment of the present utility model can install the faucet body from above the tabletop. Since the space above the tabletop is relatively spacious, it can improve the convenience of the installation operation, avoid the faucet body not being tightened due to the narrow space, and avoid problems such as the faucet body becoming loose and causing water leakage and other safety hazards caused by the faucet body not being tightened, which helps to improve the user experience.

[0035] In addition, the structure of the above faucet is simple, easy to assemble, safe and reliable in use, and is convenient for implementation and popularization.

[0036] In a third aspect, the present utility model also provides a water purifier, including the faucet provided in the second aspect of the present utility model.

[0037] Beneficial effects: The water purifier according to the third aspect of the present utility model includes or uses the faucet according to the second aspect of the present utility model, and thus has its beneficial effects, that is, the water purifier according to the embodiment of the present utility model can install the faucet body from above the countertop.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0056] The following combines Figures 1 to 9 , and describes the embodiments of the present utility model.

[0057] According to an embodiment of the present utility model, on the one hand, an installation and fixing structure for a faucet body 5 is provided, including a gasket 1, a limiting structure 3, and a connecting rod 4.

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

[0059] During the use of the installation and fixing structure for a faucet according to an embodiment of the present utility model, the operator can first place the gasket 1 under the tabletop 2, then switch the connecting rod 4 to the first state, so that the first convex portion 401 sequentially passes through the limiting hole 302 and the anti-detachment hole 102 and reaches under the gasket 1, and then switch the connecting rod 4 to the second state, so that the second convex portion 402 abuts against the tabletop 2 above the limiting hole 302, and the first convex portion 401 abuts against the tabletop 2 below the anti-detachment hole 102, thereby suspending the gasket 1 under the tabletop 2 by means of the connecting rod 4 and making the threaded hole 101 of the gasket 1 located below the installation hole 201.

[0060] By setting it in this way, the operator can pass the external thread 501 of the faucet body 5 through the installation hole 201 on the tabletop 2 (see Figure 3 and Figure 4 ), and rotate the faucet body 5 above the tabletop 2. The connecting rod 4 can cooperate with the external thread 501 and prevent the gasket 1 from rotating. 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 tightly against the lower side of the tabletop 2 (see Figure 5 and Figure 6 ), thus completing the installation.

[0061] On this basis, even if the faucet body 5 becomes loose during use, the operator only needs to tighten the faucet body 5 again above the tabletop 2. Therefore, the installation and fixing structure for the faucet body 5 according to an embodiment of the present utility model is convenient 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 5 according to an embodiment of the present utility model can install the faucet body 5 from above the tabletop 2. Since the space above the tabletop 2 is relatively spacious, it can improve the convenience of the installation operation, avoid the faucet body 5 not being tightened due to narrow space, and avoid problems such as the faucet 5 becoming loose and causing safety hazards such as water leakage due to the faucet body 5 not being tightened, which helps to improve the user experience.

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

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

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

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

[0067] When the long side of the first convex portion 401 is matched with the long side of the anti - detachment hole 102, and the short side of the first convex portion 401 is matched with the short side of the anti - detachment hole 102, the first convex portion 401 can pass through the anti - detachment hole 102.

[0068] When the long side of the first convex portion 401 is matched with the short side of the anti - detachment hole 102, both ends of the long side of the first convex portion 401 can abut against the gasket 1 on both sides of the anti - detachment hole 102.

[0069] Among them, the first convex portion 401 is preferably but not limited to a rectangular convex block, an oval convex block, a trapezoidal convex block, a parallelogram convex block or other convex blocks with irregular shapes, etc.

[0070] As a transformable implementation manner, in an embodiment not shown in one of the drawings, the dimensions of the first convex portion 401 along the first direction and the second direction are the same. The dimensions of the anti - detachment hole 102 along the first direction and the second direction are the same.

[0071] At this time, the operator can drive the connecting rod 4 to misalign the first convex portion 401 with the anti - detachment hole 102, so that the first convex portion 401 abuts against the lower side of the gasket 1, thereby realizing the anti - detachment of the gasket 1.

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

[0073] In one embodiment, the cross - sectional shape of the first convex portion 401 along the direction perpendicular to the axial direction of the connecting rod 4 is the same as the cross - sectional shape of the anti - detachment hole 102.

[0074] As a transformable implementation manner, the cross - sectional shape of the anti - detachment hole 102 can also be set to be different from the cross - sectional shape of the anti - detachment hole 102, as long as it can satisfy that the first convex block has a first state in which it can pass through the anti - detachment hole 102, and a second state in which it abuts against the hole wall of the anti - detachment hole 102 and cannot pass through the anti - detachment hole 102.

[0075] In one embodiment, the mounting and fixing structure further includes a limiting structure 3. A limiting hole 302 is provided on the limiting structure 3. The limiting structure 3 can be disposed above the tabletop 2, and the limiting hole 302 communicates with the mounting hole 201. When the connecting rod 4 is in the first state, the first convex portion 401 can pass through the limiting hole 302. When the connecting rod 4 is in the second state, the second convex portion 402 can be limited in the limiting hole 302.

[0076] By setting it in this way, the limiting structure 3 can limit the second convex portion 402 through the limiting hole 302 to prevent the connecting rod 4 from deflecting during the process of the operator rotating the external thread 501, thereby facilitating the smooth screwing of the external thread 501 into the threaded hole 101 on the gasket 1.

[0077] As an alternative embodiment, in an embodiment not shown in one of the drawings, a limiting through-hole is formed on the tabletop 2. 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 convex portion 402 abuts against the upper surface of the tabletop 2.

[0078] In one embodiment, the cross-sectional shape of the first convex portion 401 in the direction perpendicular to the axial direction of the connecting rod 4 is the same as the cross-sectional shape of the limiting hole 302.

[0079] By setting it in this way, the operator can pass the first convex portion 401 through the limiting hole 302 and the anti-disengagement hole 102 in sequence without adjusting the connecting rod 4, thereby facilitating the installation operation of the operator.

[0080] As an alternative embodiment, in an embodiment not shown in one of the drawings, the cross-sectional shape of the limiting hole 302 can also be set to be different from the cross-sectional shape of the first convex portion 401, as long as it can satisfy that when the connecting rod 4 is in the first state, the first convex portion 401 can pass through the limiting hole 302.

[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 convex portion 402 can be disposed in the limiting groove 303, and a rotation-stopping surface is formed between the groove wall of the limiting groove 303 and the second convex portion 402.

[0082] By setting it in this way, the groove wall of the limiting groove 303 can stop the rotation of the second convex portion 402, thereby preventing the connecting rod 4 from rotating as the external thread 501 rotates, and further ensuring that the gasket 1 can be in a horizontal state to facilitate the smooth screwing of the external thread 501 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 onto the plane where the tabletop 2 is located coincide.

[0084] By setting it in this way, it is not only convenient for the processing of the connecting rod 4, but also convenient for the assembly operation of the connecting rod 4.

[0085] As a transformable embodiment, in an embodiment not shown in one of the drawings, the orthographic projections of the first convex portion 401 and the second convex portion 402 onto the plane where the table 2 is located may also be set to not coincide, as long as it can be satisfied that when the connecting rod 4 is in the second state, the second convex portion 402 can abut against the upper side of the limiting structure 3, and the first convex portion 401 can abut against the lower side of the gasket 1.

[0086] In one embodiment, the cross-section of the limiting groove 303 in the direction perpendicular to the axial direction of the connecting rod 4 has the same shape as the cross-section of the second convex portion 402. When the first convex portion 401 is in the second state, the second convex portion 402 is limited in the limiting groove 303.

[0087] By setting it in this way, the limiting groove 303 can limit the second convex portion 402 in a containing manner, and at the same time guide the installation operation of the operator. The operator only needs to put the second convex portion 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 due to incomplete switching.

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

[0089] It should be noted that in the embodiments of the present application, the magnitude of the included angle between the length direction of the limiting groove 303 and the length direction of the limiting hole 302 is not limited. Exemplarily, in a preferred embodiment, the length direction of the limiting groove 303 is perpendicular to the length direction of the limiting hole 302.

[0090] In a preferred embodiment, the limiting groove 303 is further provided with a guiding groove section. The guiding groove section is arranged on the side of the limiting groove 303 away from the table 2. Along the direction approaching the table 2, the cross-sectional area of the guiding groove section gradually decreases. The guiding groove section can guide the second convex block so as to facilitate the second convex block to be put into the limiting groove 303.

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

[0092] By setting it in this way, during the assembly process, the two connecting rods 4 respectively pass through the anti-disengagement holes 102 on both sides of the threaded hole 101 and hook 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 as to facilitate the operator to screw the external thread 501 into the threaded hole 101 on the gasket 1 smoothly.

[0093] In a preferred embodiment, each pair of anti - detachment holes 102 are symmetrically distributed on both sides of the threaded hole 101, and the minimum distance between the two anti - detachment holes 102 is consistent with the minimum distance between the two limit holes 302. By setting it in this way, 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 an alternative embodiment, in an embodiment not shown in one of the drawings, the anti - detachment hole 102 can also be set to one. At this time, a rotation - preventing surface can be formed between the connecting rod 4 and the anti - detachment hole 102, and the rotation - preventing surface can prevent the gasket 1 from rotating.

[0095] As another alternative embodiment, in an embodiment not shown in one of the drawings, the anti - detachment holes 102 can also be set to more than two and are arranged at intervals along the circumferential direction of the threaded hole 101. Similarly, it can 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 in the first direction and a sixth dimension in the second direction, and the fifth dimension is greater than the sixth dimension.

[0097] Preferably, the fifth dimension is greater than the aperture of the mounting hole 201, and the sixth dimension is less than the aperture of the mounting hole 201.

[0098] By setting it in this way, during the assembly process, the operator can first pass the smaller - sized side of the gasket 1 through the mounting hole 201 of the table 2, so as to place the gasket 1 below the table 2. Then, the operator passes a finger through the mounting hole 201 of the table 2 and the threaded hole 101 and hooks the gasket 1. At this time, both ends of the long side of the gasket 1 can abut against the table 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 utility model, the operator does not need to operate below the table 2, thus avoiding the inconvenience caused by the narrow space below the table 2 to the installation operation.

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

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

[0102] At this time, the operator can place the gasket 1 from below the table 2 at the corresponding position of the mounting hole 201. Since the operator does not need to tighten the gasket 1 below the table 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 to the threaded hole 101.

[0104] By setting it in this way, the decorative cover can not only be used to limit the connecting rod 4, but also be used to block the connection part between the mounting 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, in a second aspect, there is also provided a faucet, which includes a faucet body and the installation and fixing structure for installing the faucet provided in the first aspect of the present invention.
