Description

Technical Field

[0001] This utility model relates to a faucet, which includes a mounting base connected to the body of the faucet, wherein the faucet is attached to the mounting surface by connecting the faucet to a threaded element passing through the mounting surface, and the faucet is attached to the mounting surface by tightening the connecting element from the other side of the mounting surface. Background Technology

[0002] Existing water supply faucets have an internal additional thickness in the end region of the faucet for attachment to a mounting surface, thereby providing a threaded portion that allows the faucet to be attached to a threaded attachment pipe, and the threaded portion can also pass through the mounting surface to be attached to the mounting surface by a nut or the like.

[0003] This solution for creating the threaded attachment portion of the faucet body inevitably means higher material costs in the faucet body structure, because the faucet body needs to be thickened to allow for the machining of the internal threaded portion, thereby enabling this connection between the faucet body and the threaded attachment pipe.

[0004] To facilitate their installation, many of these faucets use a base ring between the outline of the faucet body and the mounting surface to prevent water from escaping from the visible area between the inside of the faucet and the surface of the mounting surface.

[0005] When the base ring is press-fitted onto the mounting surface opposite to the mounting surface relative to the faucet position via the attachment between the threaded tube and the attachment nut, the base ring is connected to the faucet body.

[0006] The disadvantages of this base ring installation method are that it requires separate installation, and the connection of the base ring may not be perfectly concentric with the faucet body. Furthermore, because the base ring typically has a press-fit joint, the connection between the base ring and the faucet body may allow internal water to leak through the connection area between the base ring and the faucet body.

[0007] Therefore, a new configuration is needed for the attachment area between the faucet body and the mounting surface to avoid the drawbacks of known prior art. Utility Model Content

[0008] The purpose of this invention is to provide a faucet with a welded mounting base, which also solves the aforementioned disadvantages and has other advantages that will be described below.

[0009] According to this purpose, and with regard to the first aspect, the present invention is based on a faucet having a welded mounting base, wherein the mounting base includes a component configured to connect to a fixed end of the faucet body, i.e., a component connected to the portion of the faucet body closest to the mounting surface. The faucet includes a threaded attachment element in the form of a pipe, bolt, or similar material, which is attached to the faucet at one end and receives a fastening element at the other end of the threaded attachment element, the fastening element being configured to attach the faucet to the mounting surface.

[0010] Advantageously, the present invention is based on the fact that the mounting base is formed of a metal component, which includes a connecting surface configured to be securely connected to the periphery of the faucet body by welding.

[0011] Another advantage of this invention is that the mounting base includes at least one threaded opening formed by a cylindrical / annular surface configured to receive a threaded attachment element. The threaded attachment element, which is coupled to the faucet body via the mounting base, extends through the mounting surface and connects to a nut or the like, which secures the assembly to the mounting surface from the other side of the mounting surface of the faucet.

[0012] For clarity, the periphery of the faucet body should be understood as both the bottom outline of the faucet body and the lateral surfaces forming the faucet body. Similarly, the fixed end of the faucet body should be understood as the end of the faucet body adjacent to the mounting surface, and the area of ​​the faucet body adjacent to the mounting area of ​​the valve core / regulating valve. It is understood that minor variations in these positions or areas will not alter the operational or advantageous configurational concept of this invention.

[0013] The configuration advantageously allows the faucet to include internal threads without increasing the material thickness at the fixed end of the faucet. These internal threads allow for the attachment of threaded attachment elements. This material saving allows for reduced faucet costs by using separate components, such as a mounting base, which is securely connected to the faucet body via welding. This reduces material costs because the material thickness does not need to be as critical as, or the same as, the faucet body.

[0014] In addition to reducing faucet material costs, this advantageous configuration allows the mounting base to be attached to the faucet before it is installed onto the mounting surface, thus preventing improper placement, movement between the two components, or even leaks between the mounting base and the faucet body. Another advantage of this welded mounting base configuration is the continuity of the visible components, with welded joints, eliminating the need for press-fitted connection grooves.

[0015] According to a possible embodiment of the present invention, the mounting base is a metal part, and the mounting base has the following geometry: the geometric contour of the metal part is formed with a portion protruding from the bottom as a skirt or peripheral step portion visible relative to the faucet body, and the mounting base has a welding connection surface on the support surface for the peripheral portion of the faucet body contour portion.

[0016] This configuration yields a faucet with the aforementioned advantages, allowing it to be slightly raised relative to the mounting surface and enabling the faucet body to have a larger diameter thereon, thereby allowing for efficient and tight packing via connecting elements that link to the mounting base.

[0017] According to another possible embodiment of the present invention, the mounting base is a metal part, and the mounting base has the following geometry: the geometry of the mounting base is largely consistent with the geometry of the fixed end of the faucet body, and does not protrude from the periphery of the fixed end of the faucet body; the connecting surface of the mounting base is in contact with the periphery of the outline of the faucet body or the inner periphery of the faucet body by welding at the periphery end of the mounting base.

[0018] This configuration allows the same previous effect to be achieved in embodiments without skirts or visible peripheral steps that are hidden by the faucet body but are internally attached or to the same profile so that threaded attachment elements can be attached.

[0019] According to an embodiment complementary to any of the foregoing embodiments, the cylindrical / annular surface with a threaded opening forming the mounting base is configured with a receiving axis for attaching an element, the receiving axis being perpendicular to the plane of the mounting surface of the faucet.

[0020] This configuration of at least one threaded opening in the mounting base is achieved by a curved segment in the indicated axial direction of the cylindrical / annular surface, the curved segment having an annular profile that describes the threaded opening of the attachment element. Subsequently, machining the surface along this axis allows the formation of a threaded surface that replaces the thickness of the faucet body in the prior art.

[0021] The geometry of the mounting base is preferably constructed by stamping, drawing or similar processes on the metal plate forming the geometry, and the threaded opening is constructed by machining the cylindrical / annular surface.

[0022] The process of constructing the metal component corresponding to the mounting base allows for the provision of the desired external shape, circular or other shapes corresponding to the faucet body, or different desired shapes. The mounting base has an externally visible skirt or step or is adjusted to the faucet body to have a height above the mounting surface, and a threaded opening is constructed by bending, stamping or similar means to create the cylindrical / annular surface on an axis perpendicular to the mounting surface.

[0023] For any of the above embodiments, preferably for the present invention, the mounting base may have a single opening, the diameter of which corresponds to the diameter of the connecting element, such as a threaded mounting tube, wherein the connecting element is configured to allow hydraulic lines to pass through the valve core / valve inside the faucet, and to be attached from the other side of the mounting surface by means of fastening elements.

[0024] Optionally, but applicable to embodiments prior to this final embodiment, the mounting base, in addition to being configured to have a threaded opening with a reduced diameter to receive bolt or threaded rod type attachment elements, also has at least one additional opening for hydraulic lines to pass through.

[0025] Therefore, these last two configurations enable the new mounting base concept to be applied to any solution traditionally used for attaching a tap to a mounting surface.

[0026] For all the above embodiments, it should be noted that the metal component forming the mounting base preferably has the same metal material as the faucet body, or alternatively, has a material that is compatible with the metal material of the faucet body by welding.

[0030] Figure 3 Details of the fixed end of the faucet are shown, which has a welded mounting base including a threaded portion for a threaded pipe connection element, wherein the mounting base has a visible outer skirt.

[0031] Figure 4Details of the fixed end of the faucet, which has a welded mounting base including a threaded portion for a threaded pipe attachment element, wherein the mounting base does not protrude from the diameter of the faucet body. Detailed Implementation

[0032] like Figure 1 and Figure 2 As can be seen, faucets known in the prior art have an internal thickness A at the fixed end of the faucet body O, thereby allowing a thread B to be formed in this internal thickness A for connecting elements. In this example of the prior art, the faucet has a threaded tube D for passing through the mounting surface S, and this threaded tube is threaded to a nut T or the like on the other side of the mounting surface S so as to be clamped against the mounting surface S. Figure 1 and Figure 2 In this document, well-known conventional components such as valve cores / valves or faucet handles are not shown.

[0033] like Figure 2 As shown, the tap can have a base G of tap O, thereby allowing for an increase in the base diameter of tap O and improving the tight packaging described.

[0034] In a preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the faucet 10 has a fixed end 12 of the faucet body 10, which can be fixed to the mounting surface 100 without thickening because the fixed end has a mounting base 11 formed of a metal part. In this case, the mounting base is made of the same stainless steel as the body and is welded to the attachment end 12 of the faucet 10.

[0035] The mounting base 11 is constructed using conventional processes such as stamping, drawing, punching, or similar techniques. In this embodiment, a stepped profile with an outer skirt 18 and a connecting surface 15 is formed by welding the peripheral portion 16 of the faucet body 10's profile to a support surface on the mounting base 11. Furthermore, the mounting base 11 has a threaded opening 17, the diameter of which is complementary to the diameter of the connecting element 13. In this embodiment, the connecting element 13 is a threaded tube. The threaded opening 17 is formed from a cylindrical / annular surface, which is also prepared by drawing, stamping, or punching processes, followed by machining.

[0036] As an alternative to the previous embodiment with skirt 18, there is a possibility of attaching mounting base 11 to faucet body 10, which does not protrude from faucet body 10, remains invisible to the outside, and, as Figure 4As shown, the mounting base is connected by welding at the peripheral end of the mounting base 11, which contacts the peripheral edge 16 of the faucet body contour portion 10. A connecting surface 15 is provided in the connecting contour of the two components: the mounting base 11 and the peripheral edge 16 of the faucet body. Similarly, if the mounting base 11 is tightly located within the cavity of the faucet body 10, the connector can be manufactured to contact the mounting base 11 and the inner peripheral edge 16.1 of the faucet body 10.

[0037] The first end 13.1 of the connecting element 13 is attached to the mounting base 11 by a thread, the connecting element 13 passing through the mounting surface 100 so as to receive a fastening element 14 at the other end 13.2, which applies direct or indirect pressure to the other side of the mounting surface 100, thereby creating attachment of the faucet assembly 10 to the mounting surface 100.

[0038] As shown in the previous embodiment, the connecting element 13 is based on a threaded tube with a diameter similar to that of the faucet body 10, through which the hydraulic lines pass. Therefore, only a threaded opening 17 is provided at the base for the threaded attachment of the connecting element 13.

[0039] As an alternative to the above-described embodiment, a bolt or threaded rod (not shown in the figure) can be used instead. This results in a mounting base with two openings: one threaded opening for threaded attachment of this type of attachment element, having a similar configuration to a threaded opening adapted to the diameter of the threaded rod or bolt, but with a diameter much smaller than that of the threaded tube; and another opening to allow hydraulic lines to pass through. This embodiment—not shown in the figure—allows for the application of this welded mounting base configuration to different joint systems due to its similarity and extensive understanding of rod or threaded bolt joint shapes.

[0040] As shown, the joint between the mounting base 11 and the fixed end 12 of the faucet body 10 is formed by welding, which seals the joint and makes the joint groove invisible, just as in the prior art where there is an externally visible step or skirt.

[0041] Although specific embodiments of the present invention have been referenced, it will be apparent to those skilled in the art that the faucet and threaded mounting base described herein can be varied and modified in many ways, and that all the preceding details can be replaced by other technically equivalent details without departing from the scope of protection defined by the appended claims.
