Description

Rotatable combination structure of faucet

The invention relates to a faucet, in particular to a revealer of an innovative structural type of a rotatable combined structure of a faucet.

In the early vertical drinking faucets on the basin, the position of the water outlet was usually fixed. Later, in response to the diverse needs of users, the industry developed an improved structure in which the faucet can rotate left and right to adjust the angle.

The conventional structure of the faucet that can rotate left and right to adjust the angle is to install a ball turntable between the faucet and the water inlet riser, so that the faucet can obtain a rotational support state. However, this conventional structure has been found in actual use experience. , because there is an excessive assembly gap between the ball turntable, the faucet and the water inlet riser, which affects the quality and value of the overall faucet.

Others in the industry adopt a method of installing a plastic friction component between the faucet and the water inlet riser. In order to make the lower component of the plastic friction component reach a limit position and prevent it from falling off, the top of the water inlet riser is set into a shrinkage. The lower component is assembled from the bottom end of the water inlet riser and the top of the water inlet riser is partially exposed. Although this conventional structure type can achieve the advantage of a relatively compact rotating assembly part, However, the inconvenient assembly is the problem, because if the length of the water inlet riser is longer, the length should exceed 10 centimeters. After the lower component is assembled from the bottom end of the water inlet riser, there is a high chance that it will not slide smoothly. When moved to the top, it will usually get stuck in the water inlet riser and must be pushed by other tools to get it into place. The same problem is faced when replacing components, and the water inlet riser must be removed first before the lower assembly can be inlet. The bottom end of the riser is removed, so assembly and replacement are quite time-consuming and inconvenient.

The main purpose of this creation is to provide a rotatable combined structure of a faucet. The technical problem it intends to solve is to make innovative breakthroughs with the goal of developing a new faucet structure that is more ideal and practical.

Based on the above purpose, the present invention provides a rotatable combined structure of a faucet. The combined structure is used to be assembled between the rotatable water outlet part of the faucet and the faucet body, wherein an open cylindrical shape is formed on the top of the faucet body. The installation slot includes an opening and a bottom wall. The bottom wall forms a water inlet guide hole and a plurality of locking holes. The rotatable water outlet component includes a set of pipes to be inserted into the installation slot from the open opening, and The set of nozzles is formed with an inner pipe wall, an outer pipe wall and abutment end. The inner pipe wall is formed with an inner convex ring at a height position; the combined structure includes a lower fixed seat, an upper clamping seat and an upper end locking positioning member. The lower fixed base is accommodated in the installation groove. The lower fixed base includes a barrel body and a plurality of vertical axial through holes. The plurality of vertical axial through holes are opposite to the plurality of locking holes on the bottom wall of the installation groove. The barrel body has a The butting end and the barrel body are used to assemble the inner wall of the assembly pipe of the rotatable water outlet component. The butting end is limited to the bottom of the inner convex ring, and the upper clamp seat is accommodated in the inner pipe wall of the assembly pipe. Above the convex ring, the upper clamp seat includes a downwardly extending convex seat and an enlarged diameter clamping edge. The downwardly extending convex seat extends downward through the inner convex ring and abuts against the barrel end of the lower fixing seat, and forms an expanded diameter. The diameter clamping edge is located at the top of the inner convex ring, and a clamping distance is relatively defined between the diameter expansion clamping edge and the butting end of the barrel body of the lower fixed seat to produce a limiting effect on the inner convex ring; the upper clamping seat is also It has a plurality of positioning holes and a plurality of vertical axial through-holes of the lower fixing base in relative position; the upper end locking positioning member includes a plurality of bolts, so that each bolt sequentially extends through the positioning holes of the upper clamping base and the vertical axial penetration of the lower fixing base. hole, and screw-locked into the locking hole on the bottom wall of the installation slot, thereby positioning the upper clamp base and the lower fixed base together, and making the rotatable water outlet part rotatable.

Through this innovative structural form and technical features, compared with the prior art, this creation can achieve the advantage of a tighter assembly of the rotatable water outlet part of the faucet, and its upper end locking positioning member is from above. The bottom locking method allows the assembly or disassembly of the combined structure to be completed without disassembling the main body of the faucet, thereby achieving more time-saving and convenient assembly and replacement, practical progress and better industrial utilization benefits.

Another purpose of this invention is to form an expanded ring through the lower end of the barrel of the lower fixing seat. The outer diameter of the expanded ring matches the diameter of the installation groove of the faucet body, and the expanded ring can be used The abutment end of the assembly pipe of the rotatable water outlet component abuts against the limit, and the abutment end of the assembly pipe of the rotatable water outlet member is further formed with a diameter-reducing annular rib, and the diameter-expanding annular wall is correspondingly formed with an annular groove for diameter reduction. Another technical feature of the ring rib embedded fit is to make the combined state of the rotatable water outlet parts more compact and reliable, and to achieve practical advancement.

Another purpose of this invention is to provide another technical feature of leaving a gap between the abutting end of the barrel portion of the lower fixed seat and the inner convex ring of the assembly pipe. This is to prevent the problem that when the upper clamp base and the lower fixing base lock set are fixed, the clamping distance is too small, causing the rotatable water outlet component to be clamped too tightly and difficult to rotate.

Please refer to Figures 1 to 7, which are preferred embodiments of the rotatable combination structure of the faucet of the present invention. However, these embodiments are for illustration only and are not limited by this structure in patent applications.

The combined structure is used to be assembled between a rotatable water outlet part 10 of a faucet and a faucet body 20, wherein an open cylindrical installation groove 21 is formed on the top of the faucet body 20. The groove 21 includes an opening 22 and a bottom wall 23. The bottom wall 23 forms a water inlet guide hole 24 and a plurality of locking holes 25. The rotatable water outlet component 10 includes a set of pipes 11 to correspond to the opening 22. The set of nozzles 11 is inserted into the installation groove 21, and the set of nozzles 11 is formed with an inner pipe wall 12, an outer pipe wall 13 and a resisting end 14. The inner pipe wall 12 is formed with an inner convex ring 15 at a height position; the combined structure It includes a lower fixing seat 30, an upper clamping seat 40 and an upper end locking positioning member 50. The lower fixing seat 30 is accommodated in the installation groove 21. The lower fixing seat 30 includes a barrel body 31 and a plurality of The plurality of vertical axial through holes 32 are opposite to the plurality of locking holes 25 in the bottom wall 23 of the mounting groove 21. The barrel portion 31 has a resisting end 33, and the barrel portion 31 is used for The inner tube walls 12 of the set of nozzles 11 of the rotatable water outlet component 10 are matched together, and the abutment end 33 is limited to the bottom of the inner convex ring 15 , and the upper clamping seat 40 is accommodated in the inner tube of the set of nozzles 11 Above the inner convex ring 15 of the wall 12, the upper clamping base 40 includes a downwardly extending convex seat 41 and an enlarged diameter clamping edge 42. The downwardly extending convex seat 41 extends downward through the inner convex ring 15 to abut against the inner convex ring 15. The barrel portion 31 of the lower fixed seat 30 abuts the end 33 and forms the expanded diameter clamping edge 42 located at the top of the inner flange 15. The expanded diameter clamping edge 42 and the barrel portion of the lower fixed seat 30 The opposing ends 33 of 31 are relatively defined to form a clamping distance H1 to produce a limiting effect on the inner convex ring 15 of the rotatable water outlet component 10; the upper clamping base 40 also has a plurality of positioning holes 43 and the lower fixing hole 43. The plurality of vertical axial through holes 32 of the base 30 are in relative positions; the upper end locking positioning member 50 includes a plurality of bolts 51, so that each bolt 51 extends through the positioning holes 43 of the upper clamp base 40 and the lower fixing member in sequence. The vertical axial through hole 32 of the base 30 is screw-locked to the locking hole 25 of the bottom wall 23 of the installation groove 21, thereby positioning the upper clamp base 40 and the lower fixed base 30, and allowing the rotatable water outlet component to be positioned 10 is in a rotatable state.

As shown in Figure 2, in this example, the lower end of the barrel portion 31 of the lower fixed seat 30 further forms an enlarged diameter ring 34, and the outer diameter of the expanded diameter ring 34 is consistent with the installation groove 21 of the faucet body 20. The diameter of the groove matches, and the enlarged diameter ring 34 is used for the abutment end of the set of pipes 11 of the rotatable water outlet component 10 to abut against the limit.

As shown in Figures 2 and 5, in this example, the abutting end 14 of the set of pipes 11 of the rotatable water outlet component 10 is further formed with a reduced diameter annular rib 16, and the expanded diameter annular wall 34 is correspondingly formed with an annular groove 35 , for the reduced-diameter annular rib 16 to fit in. Through this example, the assembled state of the rotatable water outlet component 10 is made more compact and reliable. Because direct contact between the inner tube wall 12 of the assembly nozzle 11 and the cylinder body 31 of the lower fixing seat will increase the friction area over a large area, and a larger distance between the two can reduce friction, but will cause the rotatable water outlet component 10 to sway. Therefore, the enlarged diameter ring 34 can prevent the set of nozzles 11 from directly contacting the faucet body 20 (note: to avoid metal contact noise, because the set of nozzles 11 and the faucet body 20 are usually made of metal, and the lower fixing seat 30 The upper clamp seat 40 is usually made of plastic material), and the fitting type of the annular groove 35 and the reduced-diameter annular rib 16 can reduce the friction area and more firmly limit the rotatable water outlet component 10, making it more compact, reliable and stable. It will shake at will.

As shown in Figures 2 and 5, in this example, the downwardly extending protruding seat 41 of the upper clamping seat 40 is further formed with a relatively reduced diameter embedding portion 44, and the barrel portion 31 of the lower fixed seat 30 is pressed against The end 33 is correspondingly formed with an embedding concave surface 36 for the embedding portion 44 to be embedded and matched. The advantage of this embodiment is to further increase the stability and strength of the upper clamping base 40 and the lower fixing base 30 when they are clamped together.

As shown in FIG. 5 , in this example, a gap H2 is provided between the abutting end 33 of the barrel portion 31 of the lower fixed seat 30 and the inner convex ring 15 of the set of nozzles 11 . The type disclosed in this example is mainly used to prevent the clamping distance H1 from being too small when the upper clamping base 40 and the lower fixing base 30 are fixed, causing the rotatable water outlet component 10 to be clamped too tightly and difficult to rotate.

Furthermore, the clamping distance H1 is equal to or greater than the height of the inner convex ring 15 of the rotatable water outlet component 10 . When the value of the clamping distance H1 is equal to the value of the height of the inner convex ring 15, the rotation tightness of the rotatable water outlet component 10 is formed; conversely, when the value of the clamping distance H1 is greater than the value of the height of the inner convex ring 15, then it can The rotation tightness of the rotating water outlet component 10 is relatively loose.

As shown in FIG. 3 , in this example, a partial side of the enlarged clamping edge 42 of the upper clamp base 40 is further formed with a rotation angle limiting groove 60 , and the rotation angle limiting groove 60 has a forward end edge. 61 and a reverse end edge 62. A rotation stroke range is defined between the forward end edge 61 and the reverse end edge 62; the inner tube wall 12 of the set of nozzles 11 of the rotatable water outlet component 10 is correspondingly formed with a convex Point 17 can limit the rotatable angle of the rotatable water outlet component 10 through the limiting effect formed by the forward end edge 61 and the reverse end edge 62 on the protrusion 17 . Taking the rotation stroke range as 180 degrees as an example, the left and right rotation angle of the rotatable water outlet component 10 is as shown in Figures 6 and 7, which can relatively reach a range of 180 degrees.

As shown in Figures 8 and 9, in this example, a positioning groove 45 is formed on a partial side of the enlarged clamping edge 42 of the upper clamping seat 40; the inner pipe wall 12 of the set of nozzles 11 of the rotatable water outlet component 10 is A protruding point 17 is formed correspondingly (note: it is the same component as the protruding point 17 mentioned in the previous paragraph), so that the positioning groove 45 can engage and position the protruding point 17 to fix the state of the rotatable water outlet component 10 . This example is used to illustrate that the rotatable water outlet component can also be modified into a fixed-angle non-rotatable state according to the customer's special needs, and only needs to replace the upper clamp base 40 with a different one.
