[0003] 1. The fixing nut and the fixed pipe are assembled under the table, and the thread cannot be seen, which makes it difficult to align and install;

[0004] 2. After aligning the screw thread, rotate the lock from the bottom to the lower surface of the table. The fixing nut needs to be rotated about 12 circles (24 turns) to lock it, which will easily cause arm pain. Similarly, when disassembling, it also needs to be reversed about 12 circles (24 turns) to disassemble;

[0005] 3. The fixing nuts and other parts are made of metal, and the kitchen, bathroom and other places are humid, which can easily cause the metal parts to rust, making disassembly more difficult;

[0006] In order to improve the above defects, the R&D personnel have made further improvements, such as the authorized Chinese patent, named: A faucet quick installation and quick disassembly structure, ZL201220745036.9, the authorization announcement date is: August 14, 2013, which realizes quick installation through a quick installation structure to reduce the difficulty of installation, but such quick installation structures need to install a reset structure to realize the disassembly function, otherwise it cannot be disassembled, and because the reset structure added inside makes the volume of the entire faucet installation structure larger, it has certain requirements on the installation environment and space, and has poor adaptability; in addition, during installation, manpower is required to overcome the force of the reset structure first. It should be noted that due to the small space under the table, it is difficult for people to apply force manually, which brings greater difficulties to the installation;

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] like Figure 1 , 2 As shown, the faucet under-counter mounting assembly of the present invention is arranged below the countertop and is used to cooperate with the pipe to fix the faucet above the countertop; the mounting assembly is located and includes:

[0050] A gland 1 is arranged below the table and sleeved on the outer wall of the pipe 2;

[0051] The fastening unit 3 is sleeved on the outer wall of the pipe 2; the fastening unit 3 includes a first oblique wedge-shaped portion 31 facing the faucet or the accommodating space 30 and a base 32; in order to facilitate assembly and manufacturing, the present invention takes the fastening unit 3 as an example of a split arrangement, and the first oblique wedge-shaped portion 31 is provided on the base 32 (the first oblique wedge-shaped portion 31 and the base 32 may be connected as a whole, or may be assembled by a locking piece);

[0052] The connecting member 33 includes a through hole 331 and a stop edge 332; the through hole 331 is for the first oblique wedge-shaped portion 31 to pass through, and the outer diameter of one end of the first oblique wedge-shaped portion 31 that cooperates with the locking block 4 is larger than the aperture of the through hole 331, which effectively prevents the connection during transportation; the stop edge 332 cooperates with the gland 1 to form the accommodating space 30 for the locking block 4 to be placed, and the outer wall of the stop edge 332 forms an external thread 333 that is screwed to the gland 1;

[0053] The locking block 4 is placed in the accommodating space 30 and is provided with a second oblique wedge-shaped portion 41; the present invention takes at least two of the locking blocks 4 as an example, and each of the locking blocks 4 is further provided with a threaded portion 42 that cooperates with the external thread of the pipe 2; wherein the fastening unit 3 acts on the second oblique wedge-shaped portion 41 of the locking block 4, so that the locking block 4 is displaced radially along the pipe 2 in the accommodating space 30, and the threaded portion 42 cooperates with the external thread of the pipe 2;

[0054] The first oblique wedge-shaped portion 31 and the second oblique wedge-shaped portion 41 are assembled via a dovetail groove structure and matched via an inclined surface, so that the first oblique wedge-shaped portion 31 moves axially along the connecting pipe 2 while pushing the locking block 4 to hold or open relative to the connecting pipe 2.

[0055] Embodiment 1, as Figures 1 to 6 As shown, the first embodiment of the present invention takes the method of pushing the mounting assembly upward relative to the table surface to lock it and pulling it downward to loosen it as an example, and there is no need to use an independent reset member to achieve loosening; the details are as follows:

[0056] The installation assembly mainly includes the following components: a gland 1, a plurality of locking blocks 4, a plurality of first oblique wedge-shaped portions 31, a base 32 and a connecting member 33;

[0057] During actual assembly and use, first, the first oblique wedge-shaped portion 31 of the present embodiment is a wedge-shaped protrusion (four wedge-shaped protrusions 31 are used as an example in the present embodiment). After the wedge-shaped protrusion 31 passes through the connecting piece 33 with an external thread, it is placed on the base 32 for assembly, that is, one end of the wedge-shaped protrusion 31 is inserted into the hole provided on the base 32, and then the two are connected as one from the side of the base 32 by screws; secondly, the locking block 4 is assembled with the wedge-shaped protrusion 31; specifically, the locking block 4 is provided with a second oblique wedge-shaped portion 41 assembled corresponding to the wedge-shaped protrusion 31, and the second oblique wedge-shaped portion 41 is assembled corresponding to the wedge-shaped protrusion 31. The wedge-shaped portion 41 is a wedge-shaped groove. The wedge-shaped groove 41 here refers to an inclined groove with an inclined surface. The notch of the wedge-shaped groove 41 is arranged away from the pipe 2. It should be noted that the notch here means that the wedge-shaped groove 41 is opened away from the pipe 2, that is, the constricted part of the inclined groove is opened away from the pipe 2 (preferably, the wedge-shaped groove 41 is opened on the outer side wall of the locking block 4; wherein, when the locking block 4 is pressed and tightly embraces the pipe 2, the wedge-shaped protrusion 31 is pressed against the inner wall of the stop edge 332 and the wedge-shaped groove 41 to limit the downward movement of the slider);

[0058] The wedge-shaped groove 41 and the wedge-shaped protrusion 31 are connected by shrinking or hooking (in order to realize the clamping assembly of the wedge-shaped groove 41 and the wedge-shaped protrusion 31, a first inclined surface 43 is provided on the side of the wedge-shaped groove 41, and a second inclined surface 34 matching the first inclined surface 43 is provided on the side of the wedge-shaped protrusion 31; when the wedge-shaped protrusion 31 moves upward, the second inclined surface 34 and the first inclined surface 43 abut against each other to drive the locking block 4 to move); the clamping realized in the first embodiment is exemplified by a hook-like manner (such as Figure 4 As shown in the figure, the wedge-shaped groove 41 is a circular groove with an arc surface exceeding the radius, and when the wedge-shaped protrusion 31 is assembled with the wedge-shaped groove 41, the arc surface portion exceeding the radius is used to make the wedge-shaped protrusion 31 and the wedge-shaped groove 41 always maintain a similar hook-like fit (the present invention adopts a dovetail groove structure, that is, an inclined groove with a shrinkage), and the arc surface portion A exceeding the radius enables the two to move axially synchronously, that is, when the wedge-shaped protrusion 31 moves axially along the pipe 2, a radial component force is given to the wedge groove 41, and this component force can cause the locking block 4 with the wedge-shaped groove 41 to move radially; therefore, when the base 32 moves upward, the wedge-shaped protrusion 31 on it pushes the inclined surface of the wedge groove 41 to cooperate, so that the locking block 4 holds the pipe 2 tightly; the base 32 is forced to move downward, and the wedge-shaped protrusion 31 on it drives the wedge groove 41 that is hooked and matched with it to move outwardly through the arc surface portion A exceeding the radius, so that the locking block 4 is separated from the pipe 2;

[0059] Finally, the pressure cover 1 is screwed with the external thread 333 formed on the retaining edge 332 of the connecting member 33, and then the connecting member 33 is limitedly assembled with the base 32, that is, the first limiting protrusion 321 set on the base 32 is limitedly assembled with the first limiting groove 330 of the connecting member 33; specifically, the connecting member 33 is provided with a first limiting groove 330, a clearance groove 334 and an opening that connects the first limiting groove 330 to the outside to form a limiting match with the first limiting protrusion 321; the clearance groove 334 is formed on the side of the through hole 331 of the connecting member 33; wherein, the first limiting protrusion 321 is inserted from the opening 335 and rotated to be placed in the first limiting groove 330, and the first oblique wedge-shaped portion 31 rotates accordingly and is at least partially placed in the clearance groove 334, so that the base 32 and the connecting member 33 are limitedly connected and the wedge-shaped protrusion 31 is tightly matched with the wedge-shaped groove 41, so as to complete the assembly process of the under-table mounting component;

[0060] During installation: first, the pipe 2 of the faucet passes through the countertop and is exposed below the countertop; the installation component is integrally sleeved on the outer wall of the pipe 2, and the upper surface of the pressure cover 1 is now supported on the lower surface of the countertop, so that the installation component is directly sleeved on the lower surface of the countertop, eliminating the need to screw the lower end of the pipe 2 to the lower surface of the countertop; then, the base 32 is pushed upward, and the wedge-shaped protrusion 31 on the base 32 moves upward. At this time, the wedge-shaped protrusion 31 cooperates with the inclined surface of the wedge-shaped groove 41. Since the locking block 4 is restricted by the pressure cover 1 and cannot be displaced axially, it can only move toward the pipe 2 through the inclined surface, and finally the threaded portion 42 of the locking block 4 hugs the pipe 2. The first stopper 321 on the base 32 enters the opening 335 of the connecting piece 33 and is lifted to a certain height before being hooked and matched with the first stopper groove 330 on the outer peripheral wall of the connecting piece 33, so that the wedge-shaped protrusion 31 is always kept in the state of supporting the inclined surface of the wedge-shaped groove 41 to prevent reverse displacement. This operation method not only simplifies the installation steps, but also has a large force-applying surface of the base 32, which is convenient for holding and assembling. In addition, even if the installer does not support the gland 1 against the lower surface of the table, it can be moved by rotation, which is more applicable.

[0061] When disassembling, in the tight fit state, the base 32 is rotated in the opposite direction, and the first limiting piece on the base 32 is disengaged from the first limiting groove 330 on the connecting piece 33. At this time, the locking block 4 is no longer tightly pressed by the wedge-shaped protrusion 31 and remains in a state without force. By pulling the base 32 downward, the wedge-shaped protrusion 31 is driven to move downward. At this time, since the wedge-shaped protrusion 31 and the wedge groove 41 are in a shrinking snap connection or hooking fit, the wedge-shaped protrusion 31 and the wedge groove 41 are hooked and fit by the arc surface part A of the radius, and then the locking block 4 without force is pulled away from the outer wall of the pipe 2, so that the installation component is smoothly disassembled;

[0062] Embodiment 2, as Figures 7 to 12 As shown, the second embodiment takes the installation component as an example of pulling down and locking relative to the tabletop, and pushing up and loosening, and also does not need to use an independent reset member to achieve loosening; the same parts of the second embodiment as the first embodiment will not be repeated, and the difference is as follows:

[0063] The installation assembly mainly includes the following components: The installation assembly mainly includes the following components: a gland 1, a plurality of locking blocks 4, a plurality of first oblique wedge-shaped portions 31, a base 32 and a connecting member 33;

[0064] Actual assembly and use, first, in this embodiment, the first oblique wedge-shaped portion 31 takes the obliquely arranged wedge-shaped protrusion 31 as an example, and the second oblique wedge-shaped portion 41 is a wedge-shaped groove 41, and the notch of the wedge-shaped groove 41 is arranged toward the connecting pipe 2. Here, "the notch is arranged toward the connecting pipe 2" means that the wedge-shaped groove 41 is arranged obliquely upward toward the connecting pipe 2, that is, the inclined surface of the wedge-shaped groove 41 is arranged obliquely upward from the outside toward the connecting pipe 2. During the assembly process, the wedge-shaped protrusion 31 is first passed through the connecting piece 33 and then fixedly connected to the base 32. It should be noted that a limit ring 5 is also provided between the connecting piece 33 and the base 32. The limiting ring 5 is screwed with the connecting piece 33, and the side of the limiting ring 5 facing the base 32 limits the base 32 from moving toward the gland 1 when the locking block 4 is holding the pipe 2 tightly. Secondly, the wedge-shaped protrusion 31 is snap-fitted with the wedge-shaped groove 41 of the locking block 4, and the wedge-shaped protrusion 31 and the wedge-shaped groove 41 are matched with each other in an inclined manner (of course, a certain gap is allowed between the two, as long as it is ensured that the two will not be unable to match during the movement). The wedge-shaped protrusion 31 is forced to move upward or downward along the axial direction of the pipe 2, and the locking block 4 is opened or held tightly relative to the pipe 2 through the matching of the inclined surfaces of the two.

[0065] In this embodiment, four locking blocks 4 are taken as an example. In order to enable the locking blocks 4 to achieve synchronous movement, a second limiting structure 7 is provided on the locking blocks 4. Specifically, a second limiting protrusion 71 is provided on the side of the connecting member 33 facing the gland 1, and the locking block 4 is provided with a second limiting groove 72 that cooperates with the limiting protrusion; wherein the second limiting groove 72 cooperates with the second limiting protrusion 71 to enable the locking block 4 and the connecting member 33 to move in the same direction;

[0066] Finally, the gland 1 is threadedly connected to the connector 33 to complete the assembly of the mounting assembly.

[0067] During installation: First, the pipe 2 of the faucet passes through the countertop and is exposed below the countertop; the installation component is integrally sleeved on the outer wall of the pipe 2, and the upper surface of the pressure cover 1 is supported on the lower surface of the countertop, so that the installation component is directly sleeved on the lower surface of the countertop, eliminating the need to screw the lower end of the pipe 2 to the lower surface of the countertop; then, the base 32 is pulled downward, and the wedge-shaped protrusion 31 on the base 32 moves downward. At this time, since the wedge-shaped protrusion 31 is engaged with the wedge-shaped groove 41, the wedge-shaped protrusion 31 and the wedge-shaped groove 41 are hooked and matched by the arc surface part A of the radius, and the wedge-shaped protrusion 31 and the wedge-shaped groove 41 are matched with the inclined surface, and a radial component force is given to make the wedge The arc surface part A of the shaped groove 41 drives the locking block 4 to move toward the pipe 2, and finally holds the outer wall of the pipe 2 to achieve rapid assembly; in order to ensure that the installation component can be more firmly attached to the pipe 2, the present invention uses a limit ring 5 to prevent the locking block 4 from jumping off, specifically: after the assembly is completed, since the connecting member 33 and the pressure cover 1 are threadedly connected, and the limit ring 5 is threadedly matched with the connecting member 33, the position of the limit ring 5 on the connecting member 33 is adjusted downward, and then the base 32 is pushed downward, so that the wedge-shaped protrusion 31 on the base 32 is tightly against the locking block 4, and finally the locking block 4 can hold the pipe 2 more firmly;

[0068] During disassembly, in a tight fit state, first rotate the limit ring 5 to make it move upward relative to the connecting piece 33, so that the base 32 can drive the wedge-shaped protrusion 31 to move upward. Since the wedge-shaped protrusion 31 cooperates with the inclined surface of the wedge-shaped groove 41 of the locking block 44, the locking block 4 is restricted in axial movement by the pressure cover 1 when pushing upward, so it can only move radially outward, and finally detach from the outer wall of the connecting pipe 2, and then the installation component can be smoothly disassembled.

[0069] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
