Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 5, a first embodiment of a fastening assembly of a faucet according to the present invention includes a fastening sleeve (10a, 10b), a clamping member 20, an adjusting member 30, and an adapting sleeve 40, wherein,

the fixing sleeve (10a, 10b) is arranged opposite to the clamping piece 20, and the fixing sleeve (10a, 10b) is provided with a first clamping surface 11 facing the clamping piece 20; the inner peripheral surface of the fixing sleeve (10a, 10b) includes a first inner peripheral surface 12 that is farther from the first clamping surface 11 in the axial direction, and a second inner peripheral surface 13 that is closer to the first clamping surface 11;

the first inner peripheral surface 12 is provided with a boss structure 14, and the boss structure 14 is provided with a first adjusting hole 141; the second inner peripheral surface 13 is provided with a circle of internal gear shaping 15, and the first adjusting hole 141 and the internal gear shaping 15 both extend along the axial direction of the fixed sleeves (10a, 10 b);

the clamping piece 20 has a second clamping surface 21 facing the fixing sleeve (10a, 10b), a clamping space (S) being formed between the second clamping surface 21 and the first clamping surface 11; the clamping piece 20 is provided with a second adjusting hole 22 with internal threads;

the adjuster 30 has a head 31 and a screw 32, and the head 31 abuts against a surface of the boss structure 14 away from the holder 20; the screw part 32 passes through the first adjusting hole 141 and is in threaded connection with the second adjusting hole 22 to adjust the size of the clamping space (S);

the adapting set 40 comprises an inner embedded end 41 and an outer connecting end 42 which are axially connected with each other, the inner embedded end 41 is detachably fixed in the inner cavity of the fixing sleeve (10a, 10b), and the outer peripheral surface of the inner embedded end 41 is provided with a circle of outer inserting teeth 411 which are meshed with the inner inserting teeth 15; at least a portion of head 31 of adjuster 30 is located between inset end 41 and boss structure 14; the external connection end 42 protrudes from the fixing sleeve (10a, 10b) and is provided with a threaded connection 421.

In this embodiment, the fixing sleeves (10a, 10b), the clamping member 20, the adjusting member 30 and the fitting sleeve 40 are made of metal materials. Since the covers (10a, 10b) have exposed portions, the external surfaces of the covers (10a, 10b) are usually provided with a coating having both protective and decorative effects. The first clamping surface 11 of the fixing sleeve (10a, 10b) is used for abutting against the table surface at the edge of the mounting hole 100, the second clamping surface 21 of the clamping piece 20 is used for abutting against the lower surface at the edge of the mounting hole 100, and the rotation of the adjusting piece 30 to reduce the clamping space (S) can enable the fixing sleeve (10a, 10b) and the clamping piece 20 to clamp the edge of the mounting hole 100. The arrangement of the boss structure 14 can avoid excessively reducing the inner cavity of the fixing sleeve (10a, 10b) while locally increasing the wall thickness of the fixing sleeve (10a, 10b) to facilitate the opening of the first adjusting hole 141, thereby making more space for adapting to the water inlet pipe of the water faucet and the water outlet pipe of the water faucet 40. The threaded connection 421 of the external connection end 42 is used to connect with the internal thread of the faucet.

Referring to fig. 13, which illustrates an embodiment of the faucet mounting tool translating relative to the mounting hole 100, specifically, in the case shown in fig. 13, the mounting hole 100 is circular, the fixing sleeve (10a, 10b) and the fitting sleeve 40 are both cylindrical, in the upper diagram of fig. 13, the circle O2 of the fixing sleeve (10a, 10b) coincides with the circle center O3 of the mounting hole 100, and the fixing sleeve (10a, 10b) is moved along the arrow M in the upper diagram of fig. 13 with the table top of the sanitary installation as a fixed reference; then, when the distance D is moved, as shown in the lower diagram of fig. 13, in a top view projection, the inner peripheral surface or the inner wall surface of the fixed sleeve (10a, 10b) is inscribed in the edge of the mounting hole 100, and the outer peripheral surface or the outer wall surface of the fixed sleeve (10a, 10b) on the other side is outwardly beyond the edge of the mounting hole 100 by a distance, because the end surface of the embedded end 41 close to the clamping member 20 is flush with the first clamping surface 11 or is farther away from the first clamping member 20 than the first clamping surface 11, on the basis of the lower diagram of fig. 13, the embedded end 41 of the fitting sleeve 40 is continuously moved along the arrow M without interfering with the edge of the mounting hole 100, so that the radial width of the first clamping surface 11 of the fixed sleeve (10a, 10b) can better adapt to mounting holes 100 with different sizes or to other non-circular irregular mounting holes 100.

The fixing component of the water faucet is connected with the water faucet through the detachable matching sleeve 40, when the diameters of threaded holes of the water faucet needing to be replaced are different, only the matching sleeve 40 with the matching size needs to be replaced correspondingly, and moreover, as the matching sleeve 40 is arranged in the inner cavity of the fixing sleeve (10a, 10b), when the water faucet is sleeved at the upper end of the matching sleeve 40, the water faucet is more easily flush with the outer peripheral surface of the fixing sleeve (10a, 10b), namely, no drop or small drop exists between the outer peripheral surface of the water faucet and the outer peripheral surface of the fixing sleeve (10a, 10b) in the radial direction.

The mating sleeve 40 is engaged with the sleeve (10a, 10b) by means of a toothed engagement, which provides a more secure circumferential stop and thus a greater support torque when the faucet is being screwed. The fixing sleeves (10a, 10b) and the clamping members 20 are fixedly matched with the edges of the mounting holes 100 of the bathroom facilities in a manner of reducing the clamping space (S), so that the faucet can be stably supported. Because the outer gear teeth 411 and the inner gear teeth 15 are all arranged in a whole circle, when the fixed sleeves (10a and 10b) are completely clamped on the table top, the adaptive set 40 can also adjust the radian of any number of inner gear teeth 15 or outer gear teeth 411 along the circumferential direction relative to the fixed sleeves (10a and 10b), thereby ensuring the accurate orientation of the water outlet of the water faucet. Moreover, the matching set 40 can be replaced independently, so that the product serialization is easier to realize, and the overall product cost is reduced. The invention improves the application range of the fixed component of the water tap through a series of improvements and reduces the overall cost of the product.

Furthermore, the outer peripheral surface of the fixing sleeve (10a, 10b) is provided with a first fixing hole 16 at a position corresponding to the embedded end 41, and the first fixing hole 16 penetrates through the inner peripheral surface of the fixing sleeve (10a, 10 b); the fixing assembly of the faucet further comprises a first fastening member 50, the first fastening member 50 is fixedly connected with the first fixing hole 16, and the inner end of the first fastening member 50 is fixedly abutted with the outer peripheral surface of the fitting 40.

In this embodiment, the second fastening member 70 is fixedly abutted against the outer insertion teeth 411, so that a limit is provided for the adapter sleeve 40 in the axial direction, and the adapter sleeve 40 is prevented from being disengaged from the fixing sleeve (10a, 10b) in a direction away from the clamping member 20.

Further, in the inner insertion end 41 and the outer connection end 42 of the adapter sleeve 40, the inner circumferential surface of the inner insertion end 41 is flush with the inner circumferential surface of the outer connection end 42, and the outer circumferential surface of the inner insertion end 41 radially protrudes from the outer circumferential surface of the outer connection end 42.

In this embodiment, the inner peripheral surface of the adapter sleeve 40 is flush and level, so that the circumferential obstruction can be reduced, and the water inlet pipe can be moved in the inner part of the adapter sleeve 40 along the circumferential direction more conveniently. Setting the wall thickness of the embedded end 41 to be greater than the wall thickness of the external connection end 42 can relatively increase the strength of the embedded end 41, i.e., increase the resistance to lateral pressure; the radial height of the outer gear 411 may also be set higher, thereby increasing the circumferential limit strength.

Further, with reference to fig. 14 and 15, in a second embodiment of the invention, the outer peripheral surface of the fixing sleeve (10a, 10b) comprises a first side surface 11b and a second side surface 12b which are parallel and opposite to each other, and a third side surface 13b and a fourth side surface 14b which are parallel and opposite to each other, the first side surface 11b being perpendicular to the third side surface 13 b; the first fixing hole 16 is a screw hole and is opened on the first side surface 11b, and an axial direction of the first fixing hole 16 is perpendicular to the first side surface 11 b.

In this embodiment, several outer sides of the fixing sleeves (10a, 10b) can provide positioning references, so as to more conveniently direct the water outlet pipe of the water faucet towards the right front.

Further, referring to fig. 1, 2, 8 to 12, in an embodiment, the boss structure 14 includes a base 142 and a lug 143, the base 142 is protruded on an inner circumferential surface of the fixing sleeve (10a, 10b), a receiving groove 144 is disposed at a connection portion of the base 142 and the fixing sleeve (10a, 10b), the receiving groove 144 has a groove wall surface extending along an axial direction of the fixing sleeve (10a, 10b), the lug 143 extends from the groove wall surface toward an axis of the fixing sleeve (10a, 10b), and the first adjusting hole 141 is opened on the lug 143.

In the embodiment, the boss structures 14 are arranged in a step-by-step stacking structure, so that the occupation of the internal space of the fixing sleeve (10a, 10b) is further reduced while the structural strength of the fixing sleeve is ensured, for example, the head part 31 of the adjusting piece 30 is arranged on the side of the lug 143 far away from the clamping piece 20, and the compact design of the structure is realized. It can be understood that, in this structure, the adapter sleeve 40 also achieves a limiting effect on the head 31 of the adjusting member 30, which can prevent the adjusting member 30 from loosening, thereby keeping the size of the clamping space (S) stable.

Further, in the circumferential direction of the fixing sleeve (10a, 10b), the base 142 protrudes relatively from the lug 143; the outer peripheral surface of the fixed sleeve (10a, 10b) is provided with a first through hole 17 at the position corresponding to the protruding lug 143 of the base 142, and the first through hole 17 extends into the base 142 and penetrates through the base 142;

the fixing component of the water tap also comprises a limiting strip 60 and a second fastener 70, wherein the limiting strip 60 and the adjusting piece 30 both extend along the axial direction of the fixing sleeves (10a, 10 b);

the limiting strip 60 comprises a fixed end 61 and a limiting end 62, a second fixing hole 611 is formed in the fixed end 61, and a second fastening piece 70 penetrates through the first through hole 17 and is fixedly connected with the second fixing hole 611;

the limiting end 62 of the limiting strip 60 is located on one side of the clamping piece 20 close to the axis of the fixing sleeve (10a, 10b), and when the adjusting piece 30 is screwed forward relative to the clamping piece 20 to reduce the clamping space (S), the clamping piece 20 is abutted against the limiting end 62.

In this embodiment, the base 142 may also locally reinforce the strength of the side wall of the fixing sleeve (10a, 10b), and by forming the first through hole 17 on the base 142, the strength of the fixing sleeve (10a, 10b) is prevented from being weakened while the connection of the limiting strip 60 is facilitated. The upper end of the position-limiting strip 60 is fixedly connected with the fixing sleeve (10a, 10b) through the cooperation of the first fixing hole 16 and the first fastening member 50, in a specific example, the first fixing hole 16 may be a threaded hole, the first fastening member 50 may be a bolt, such as an inner hexagonal bolt, and the head 31 of the first fastening member 50 of the inner hexagonal bolt may be conveniently hidden. The clamping member 20 is circumferentially limited by the limiting strip 60, so that the installation operation under the table top of the bathroom facility can be further reduced, and the adjustment of the size of the clamping space (S) can be realized only by rotating the adjusting member 30 above the table top.

Further, the inner diameter of the first inner peripheral surface 12 is smaller than the inner diameter of the second inner peripheral surface 13, and an inner shoulder 18 is formed at the junction of the first inner peripheral surface 12 and the second inner peripheral surface 13.

In the embodiment, the inner shoulders 18 are formed on the inner peripheral surfaces of the fixing sleeves (10a, 10b), so that the torsion resistance of the fixing sleeves is increased by increasing the step surfaces; in addition, the arrangement of the inner shoulder 18 also facilitates the processing of the inner gear 15.

Further, the internal insertion tooth 15 is offset from the edge of the first inner peripheral surface 12 near the first clamping surface 11 in the axial direction of the fixed sleeve (10a, 10b), with a gap formed between the internal insertion tooth 15 and the base 142.

In this embodiment, a gap is formed between the inner insert tooth 15 and the base 142 to ensure the machining of the inner insert tooth 15, and on the other hand, when the inner insert tooth 411 is assembled with the adapter sleeve 40, the edge of the outer insert tooth 411 close to the clamping piece 20 can exceed the inner insert tooth 15, so as to ensure a more sufficient insertion fit.

Further, referring to fig. 1 to 3 and 5 to 9, in an embodiment, the clamping member 20 extends in a circular arc shape and includes a proximal end 23 and a distal end 24;

the concave side of the clamping member 20 is provided with a convex part 25 adjacent to the proximal end 23, and a first guide groove 26 and a second guide groove 27 which are positioned at two sides of the convex part 25, and the width of the first guide groove 26 is smaller than that of the second guide groove 27;

a first guide slot 26 is located between the proximal end 23 and the boss 25, and a second guide slot 27 is located between the boss 25 and the distal end 24 and is disposed adjacent to the boss 25; the adjusting hole is arranged adjacent to the first guide groove 26 and the convex part 25;

when the adjusting member 30 is screwed forward relative to the clamping member 20 to reduce the clamping space (S), the first guide groove 26 is engaged with the limiting end 62 of the limiting strip 60 and is slidably fitted along the axis of the fixing sleeve (10a, 10 b); when the adjusting member 30 is screwed reversely to the holding member 20 to expand the holding space (S), the second guide groove 27 is engaged with the stopper end 62 of the stopper bar 60 and slidably fits the axis of the fixing sleeve (10a, 10 b).

In this embodiment, since the clamping member 20 is integrally arc-shaped, when the clamping space (S) is adjusted to a suitable size, the faucet mounting tool is tilted integrally, so that the distal end 24 of the clamping member 20 passes through the mounting hole 100, then the faucet mounting tool is rotated integrally, so that the clamping member 20 is gradually placed below the table top, then the adjusting member 30 and the limiting strip 60 integrally pass through the mounting hole 100, and finally the adjusting member 30 is operated to reduce the size of the clamping space (S) to clamp the faucet mounting tool. Thus, the related mounting operation can be completed completely above the table top, thereby reducing the mounting difficulty.

In order to ensure the strength of the clamping member 20 and/or to reduce the space occupation while providing the second adjustment hole 22, the concave side of the clamping member 20 is provided with a convex portion 25, and the second adjustment hole 22 is provided adjacent to the convex portion 25. Further, in order to adjust the size of the clamping space (S) more quickly, as shown in fig. 7, the first guide groove 26 is located substantially between the radial lines R1 and R2, and on the lower right side of the tangent line L1; the second guide groove 27 is located substantially radially between the lines R2 and R3 and on the lower right side of the tangent line L1. When the clamping space (S) needs to be reduced, the first guide groove 26 of the clamping piece 20 is buckled with the limit strip 60 and slides towards the direction close to the first clamping surface 11; when the clamping space (S) needs to be enlarged, the clamping member 20 swings to be fastened with the limiting strip 60 or the water inlet pipe, so that the clamping member can slide in the direction away from the first clamping surface 11 quickly.

Further, the first clamping surface 11 is provided with an annular groove 19 between the inner peripheral surface and the outer peripheral surface of the fixing sleeve (10a, 10b), and the annular groove 19 is used for installing an elastic sealing ring;

the clamping member 20 comprises a rigid body 28 and a flexible outer cover 29, the second adjusting hole 22 is formed in the body 28, the outer cover 29 covers one surface of the body 28 close to the fixing sleeves (10a, 10b), the concave side surface and the convex side surface of the body 28, the outer cover 29 is provided with a second through hole 291 corresponding to the adjusting hole, and the concave side portion of the outer cover 29 is provided with a clearance opening 292 corresponding to the convex portion 25, the first guide groove 26 and the second guide groove 27.

In this embodiment, by providing the annular groove 19, after the elastic sealing ring is installed in the annular groove 19, the sealing performance between the first clamping surface 11 and the table top provided with the installation hole 100 can be increased. In addition, the elastic deformation provided by the sealing ring and the outer cover 29 can compensate the clearance generated by loosening, so that the installation tool of the water faucet is more stably fixed. The outer cover 29 is provided with the clearance gap, so that the contact between the outer cover 29 and the limiting strip 60 can be reduced, and friction force is reduced in the sliding process of the clamping member 20 along the limiting member, so that the clamping member 20 can slide more smoothly.
