Description

Technical Field

[0001] This invention relates to the field of hardware and plumbing technology, and in particular to an adjustable depth wall-mounted faucet. Background Technology

[0002] With the continuous improvement of people's living standards and production levels, faucet products have undergone tremendous changes in terms of function and appearance compared to the past, with various professional functions and novel styles emerging.

[0003] Existing wall-mounted faucets use relatively long valve stems. When assembling the handle assembly, the distance between the handle assembly and the wall-mounted valve body is adjusted by cutting the valve stem to a different length, or the distance between the handle and the valve stem is fixed. However, when installers bury the main body in the wall, the burial depth cannot be consistent. This results in a situation where, if the main body is buried shallowly, the distance between the decorative panel and the handle increases after installation; conversely, if the main body is buried deeply, the distance between the decorative panel and the handle decreases. Therefore, regardless of whether the distance between the decorative panel and the handle increases or decreases after installation, it will affect the product's aesthetics and actual performance. Summary of the Invention

[0004] To address the aforementioned shortcomings, the present invention aims to propose an adjustable-depth wall-mounted faucet to solve the problem that the distance between the handle and the wall varies with the depth of the wall-mounted body, affecting the product's aesthetics and actual performance.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An adjustable depth wall-mounted faucet includes a wall-mounted body, a handle assembly, a connector, and an adjustment assembly, wherein the wall-mounted body and the handle assembly are connected via the adjustment assembly;

[0007] The wall-mounted main body includes a valve core shaft, which is fixedly connected to the connecting piece;

[0008] The handle assembly includes a handle base and a linkage shaft. One end of the linkage shaft is fixedly connected to the handle base, and the other end of the linkage shaft has an axially provided slide. The rotation of the handle base drives the linkage shaft to rotate.

[0009] The end of the connector away from the valve spindle is located in the slide rail and is slidably disposed in the slide rail. The rotation of the linkage shaft drives the connector to rotate, and the rotation of the connector drives the valve spindle to rotate.

[0010] The adjustment assembly includes an adjustment nut and an adjustment seat. The adjustment seat is fixedly connected to the bottom of the handle assembly. One end of the adjustment nut is fixedly connected to the wall-embedded body, and the other end passes through the adjustment seat and is threadedly connected to the adjustment seat. By rotating the adjustment seat, the connecting piece moves on the adjustment nut and slides in the slide rail, thus changing the distance between the handle assembly and the wall-embedded body.

[0011] Furthermore, the end of the connector away from the valve spindle passes through the adjusting nut and is located within the slide rail.

[0012] Furthermore, the connector has a hollow structure and is provided with an internal toothed section and an external toothed section;

[0013] The inner side of the internal tooth section is provided with a boss, and the inner wall surface of the internal tooth section is provided with internal teeth that cooperate with the outer periphery of the valve core shaft. The internal tooth section is sleeved on the valve core shaft, and the top end of the valve core shaft abuts against the boss.

[0014] The outer surface of the outer tooth section is connected to the inner wall tooth surface of the slide.

[0015] Furthermore, the handle assembly also includes a sleeve, which is sleeved on the outer periphery of the linkage shaft, and the linkage shaft is rotatably located inside the sleeve.

[0016] The adjusting seat has a fixed section and an adjusting section. The outer side of the fixed section is threaded to the inner wall of one end of the sleeve. The adjusting section is threaded to the adjusting nut. By rotating the adjusting section, one end of the adjusting nut is inserted into the sleeve.

[0017] Furthermore, the handle assembly also includes a friction ring;

[0018] The linkage shaft includes a mounting shaft section and a sliding shaft section. One end of the mounting shaft section is fixedly connected to the handle seat, and the other end is connected to the sliding shaft section.

[0019] The slide rail is located inside the slide groove shaft section, the slide groove shaft section is provided with a first positioning boss along the circumferential direction, and the sleeve is provided with a second positioning boss inside the sleeve.

[0020] The friction ring is sleeved on the sliding shaft section, the inner side of the friction ring is in contact with the outer side and bottom of the first positioning boss, the outer side of the friction ring abuts against the second positioning boss, and the sliding shaft section is rotatably disposed within the friction ring.

[0021] Furthermore, the handle assembly also includes a limiting nut;

[0022] The limiting nut passes through the mounting shaft section and is sleeved inside the sliding shaft section. The outer side of the limiting nut is threadedly connected to the inner wall of the sleeve. The end face of the limiting nut facing the first positioning boss abuts against the friction ring.

[0023] Furthermore, the embedded wall body also includes a valve body, and the adjusting nut is sleeved on the outer periphery of the valve core shaft, and the adjusting nut is threadedly connected to the valve body.

[0024] Furthermore, it also includes a water outlet, one end of which has a water inlet channel;

[0025] The wall-mounted main body also includes a water outlet connector. One end of the water outlet connector is threadedly connected to and communicates with the valve body. The other end of the water outlet connector is inserted into the water inlet channel and is slidably disposed. The water outlet of the water outlet connector is connected to the water outlet of the water nozzle.

[0026] Furthermore, it also includes a locking nut, which is used to fix the water outlet and the water outlet connector, and the outer wall of the water outlet is provided with a mounting hole for installing the locking nut.

[0027] In an optional embodiment, the number of the handle assembly, the connector, and the adjustment assembly are all two, and the wall-mounted body includes two valve spindles, with the two handle assemblies, the two connectors, and the two adjustment assemblies respectively installed corresponding to the valve spindles.

[0028] The technical solution provided by this invention may include the following beneficial effects:

[0029] The wall-mounted main body and the handle assembly mounted on the wall are connected by an adjusting component. The adjusting nut of the adjusting component is fixedly connected to the wall-mounted main body, and the adjusting seat is fixedly connected to the handle assembly. A connecting piece is also provided. One end of the connecting piece is fixedly connected to the valve core shaft, and the other end is located in the slide of the linkage shaft connected to the handle seat. The connecting piece slides in the slide, allowing for some adjustment. Rotating the adjusting seat on the adjusting nut, through threaded transmission, moves the entire handle assembly closer to the wall until the bottom end face of the adjusting seat is in contact with the wall, changing the distance between the handle assembly and the wall-mounted main body. Furthermore, the rotation of the handle seat causes the valve core shaft to rotate through the linkage shaft and the connecting piece. Therefore, the wall-mounting depth of the wall-mounted main body can be adjusted by the adjusting component, ensuring the handle assembly is fixedly installed on the wall. This solves the problem that the distance between the handle assembly and the wall changes with the wall-mounting depth, affecting the product's aesthetics and actual performance.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] The following is in conjunction with the appendix Figures 1 to 9 The technical solution of the present invention will be further illustrated through specific embodiments.

[0044] An adjustable depth wall-mounted faucet includes a wall-mounted body 1, a handle assembly 2, a connector 3, and an adjustment assembly 4, wherein the wall-mounted body 1 and the handle assembly 2 are connected by the adjustment assembly 4.

[0045] The wall-embedded body 1 includes a valve core shaft 11, which is fixedly connected to the connecting member 3.

[0046] The handle assembly 2 includes a handle base 21 and a linkage shaft 22. One end of the linkage shaft 22 is fixedly connected to the handle base 21, and the other end of the linkage shaft 22 is provided with an axial slide 221. The rotation of the handle base 21 drives the linkage shaft 22 to rotate.

[0047] The end of the connector 3 away from the valve spindle 11 is located in the slide 221 and is slidably disposed in the slide 221. The rotation of the linkage shaft 22 drives the connector 3 to rotate, and the rotation of the connector 3 drives the valve spindle 11 to rotate.

[0048] The adjustment assembly 4 includes an adjustment nut 41 and an adjustment seat 42. The adjustment seat 42 is fixedly connected to the bottom of the handle assembly 2. One end of the adjustment nut 41 is fixedly connected to the wall-embedded body 1, and the other end passes through the adjustment seat 42 and is threadedly connected to the adjustment seat 42. By rotating the adjustment seat 42, the adjustment nut 41 moves, and the connecting piece 3 slides in the slide rail 221, thus changing the distance between the handle assembly 2 and the wall-embedded body 1.

[0049] like Figure 1 and Figures 5 to 7 As shown, the present invention proposes an adjustable depth wall-mounted faucet, which connects the wall-mounted main body 1 installed in the wall and the handle assembly 2 installed on the wall surface through an adjustment assembly 4. The adjustment nut 41 of the adjustment assembly 4 is fixedly connected to the wall-mounted main body 1, and the adjustment seat 42 is fixedly connected to the handle assembly 2. At the same time, a connecting piece 3 is provided. One end of the connecting piece 3 is fixedly connected to the valve core shaft 11, and the other end is located in the slide 221 of the linkage shaft 22 connected to the handle seat 21. The connecting piece 3 slides in the slide 221 and has a certain adjustment space. Rotating the adjustment seat 42 through the threaded transmission on the adjustment nut 41 can make the entire handle assembly 2 move closer to the wall surface until the bottom end face of the adjustment seat 42 is in contact with the wall surface, so that the distance between the handle assembly 2 and the wall-mounted main body 1 changes. Moreover, the rotation of the handle seat 21 can make the valve core shaft 11 rotate through the linkage shaft 22 and the connecting piece 3. Therefore, the embedment depth of the wall-mounted main body 1 can be adjusted by adjusting the component 4, so that the handle component 2 can be fixedly installed on the wall. This solves the problem that the distance between the handle component 2 and the wall changes with the embedment depth of the wall-mounted main body 1, which affects the aesthetics and actual use of the product.

[0050] In some embodiments, the end of the connector 3 away from the valve spindle 11 passes through the adjusting nut 41 and is located in the slide 221, which makes it more convenient to position and connect the handle assembly 2 and the wall-mounted body 1, and the structure is simple.

[0051] Furthermore, such as Figure 8 As shown, the connector 3 has a hollow structure and is provided with an internal toothed section 31 and an external toothed section 32.

[0052] The inner side of the internal tooth section 31 is provided with a boss 311, and the inner wall surface of the internal tooth section 31 is provided with internal teeth that cooperate with the outer periphery of the valve spindle 11. The internal tooth section 31 is sleeved on the valve spindle 11, and the top end of the valve spindle 11 abuts against the boss 311.

[0053] The outer surface of the outer tooth section 32 is connected to the inner wall tooth surface of the slide 221.

[0054] Specifically, by providing a boss 311 in the inner tooth section 31 of the connector 3 and providing inner teeth on the inner wall surface that cooperate with the outer periphery of the valve core shaft 11, one end of the connector 3 is fixed on the valve core shaft 11, and the outer tooth section 32 is connected to the inner teeth of the slide 221, so that the connector 3 is connected and linked with the valve core shaft 11 and the linkage shaft 22 respectively.

[0055] Furthermore, a boss 311 is provided inside the internal tooth section 31, and the valve spindle 11 abuts against the boss 311. Screws can be inserted through the boss and screwed into the valve spindle 11 so that the connector 3 is fixed on the valve spindle 11.

[0056] In some embodiments, such as Figure 9 As shown, the handle assembly 2 also includes a sleeve 23, which is sleeved on the outer periphery of the linkage shaft 22, and the linkage shaft 22 is rotatably located inside the sleeve 23.

[0057] The adjusting seat 42 is provided with a fixed section 421 and an adjusting section 422. The outer side of the fixed section 421 is threadedly connected to the inner wall of one end of the sleeve 23. The adjusting section 422 is threadedly connected to the adjusting nut 41. By rotating the adjusting section 422, one end of the adjusting nut 41 is inserted into the sleeve 23.

[0058] To further explain, the sleeve 23 is threadedly connected to the fixed section 421 of the adjusting seat 42. The adjusting nut 41 can be inserted into the sleeve 23 through the threaded transmission with the adjusting section 422, increasing the adjustable space of the distance between the adjusting assembly 4, the adjusting handle assembly 2 and the wall-mounted body 1. This allows the handle assembly 2 to adapt to different installation depths of the wall-mounted body 1. In addition, the sleeve 23 allows the linkage shaft 22 and the connecting piece 3 to be hidden inside the sleeve 23, reducing the exposure of the connection structure between parts and improving the service life of the wall-mounted water tap.

[0059] Furthermore, the handle assembly 2 also includes a friction ring 24;

[0060] like Figure 8 As shown, the linkage shaft 22 includes a mounting shaft section 222 and a sliding shaft section 223. One end of the mounting shaft section 222 is fixedly connected to the handle seat 21, and the other end is connected to the sliding shaft section 223.

[0061] The slide rail 221 is provided inside the slide groove shaft section 223. The slide groove shaft section 223 is provided with a first positioning boss 224 in the circumferential direction, and the sleeve 23 is provided with a second positioning boss 231 inside.

[0062] The friction ring 24 is sleeved on the sliding shaft section 223. The inner side of the friction ring 24 is in contact with the outer side and bottom of the first positioning boss 224. The outer side of the friction ring 24 abuts against the second positioning boss 231. The sliding shaft section 223 is rotatably disposed within the friction ring 24.

[0063] To further explain, a first positioning boss 224 is provided on the outer periphery of the sliding end 223 of the linkage shaft 22, and a second positioning boss 231 is provided inside the sleeve 23. A friction ring 24 is provided between the first positioning boss 224 and the second positioning boss 231 to fix the linkage shaft 22 inside the sleeve 23. The linkage shaft 22 rotates within the friction ring 24, which not only reduces the amount of shaking of the linkage shaft 22, but also reduces the coefficient of friction of the linkage shaft 22 during use, making the rotation smooth.

[0064] Preferably, the friction ring 24 is made of POM material.

[0065] Furthermore, the handle assembly 2 also includes a limiting nut 25;

[0066] The limiting nut 25 passes through the mounting shaft section 222 and is sleeved inside the sliding shaft section 223. The outer side of the limiting nut 25 is threadedly connected to the inner wall of the sleeve 23. The end face of the limiting nut 25 facing the first positioning boss 224 abuts against the friction ring 24.

[0067] Understandably, such as Figure 9 As shown, the inner diameter of the limiting nut 25 is larger than the outer diameter of the mounting shaft section 222, and the plane on which the upper surface of the first positioning boss 224 is located is slightly lower than the plane on which the upper surface of the friction ring 24 is located. The limiting nut 25 is set to fix the linkage shaft 22 and prevent the linkage shaft 22 from being pulled out.

[0068] Preferably, such as Figure 3 As shown, a decorative cover 232 is provided at the end of the sleeve 23 facing the handle seat 21. The decorative cover 232 is threadedly connected to the sleeve 23. The mounting shaft section 222 of the linkage shaft 22 passes through the decorative cover 232 and is fixedly connected to the handle seat 21, making the handle assembly 2 more aesthetically pleasing.

[0069] In some embodiments, the wall-mounted main body 1 further includes a valve body 12, and the adjusting nut 41 is sleeved on the outer periphery of the valve core shaft 11. The adjusting nut 41 is threadedly connected to the valve body 12, which makes the installation structure simple, the number of parts few, and the disassembly and assembly more convenient.

[0070] In some embodiments, such as Figures 5 to 7 As shown, it also includes a water outlet 5, and one end of the water inlet of the water outlet 5 is provided with a water inlet channel 51;

[0071] The wall-mounted main body 1 also includes a water outlet connector 13. One end of the water outlet connector 13 is threadedly connected to and communicates with the valve body 12. The other end of the water outlet connector 13 is inserted into the water inlet channel 51 and is slidably disposed. The water outlet of the water outlet connector 13 is connected to the water outlet of the water outlet 5.

[0072] It is worth noting that the water outlet 5 has a water inlet channel 51 at its inlet, and the valve body 12 of the wall-mounted body 1 is threaded with a water outlet connector 13. The water outlet connector 13 is inserted into the water inlet channel 51, so that the water outlet connector 13 can slide within the water inlet channel 51 of the water outlet 25, providing a certain adjustment space, thereby enabling the water outlet 5 to adapt to different installation depths of the wall-mounted body 1.

[0073] Preferably, such as Figure 2 As shown, several sealing O-rings 131 are installed at one end of the water outlet connector 13 that enters the water inlet channel 51, so that the water outlet connector 13 can play a water seal effect in the water inlet channel 51, and at the same time reduce friction when sliding in the water inlet channel 51.

[0074] Furthermore, such as Figure 4 As shown, it also includes a locking nut 52, which is used to fix the water outlet 5 and the water outlet connector 13. The outer wall of the water outlet 5 is provided with a mounting hole 521 for installing the locking nut 52.

[0075] Specifically, the inner locking nut 52 is screwed into the mounting hole 521 near the water inlet of the water outlet 5 to fix the water outlet connector 13 onto the water outlet 5. Installation and disassembly are convenient and no other accessories are required.

[0076] Preferably, one end of the water inlet of the water outlet 5 is provided with a water outlet base 53, and the water outlet 5 is vertically installed on the water outlet base 53. During installation, a sealing ring is added to the end face of the water outlet base 53 and then it fits against the wall. The water outlet connector 13 passes through the water outlet base 53 and enters the water inlet channel 51, making the water outlet 5 more stable when installed on the wall.

[0077] It is worth noting that, such as Figure 5 As shown, before installation, the wall-mounted main body 1, connector 3 and adjusting nut 41 are assembled into one unit, the handle assembly 2 and adjusting seat 42 are assembled into one unit, and the water outlet 5 and water outlet base 53 are assembled into one unit. All parts are assembled before shipment, so that end users and plumbers do not need to do any additional assembly work, reducing the risk of parts being lost or damaged.

[0078] In some embodiments, such as Figure 1 and Figure 2As shown, there are two handle assemblies 2, two connectors 3 and two adjustment assemblies 4. The wall-mounted body 1 includes two valve spindles 11, and the two handle assemblies 2, the two connectors 3 and the two adjustment assemblies 4 are respectively installed with the valve spindles 11.

[0079] Specifically, two valve cores 11 are provided, one for cold water outlet and the other for hot water outlet, thereby improving the applicability of the wall-mounted faucet. It should be noted that the structure of the wall-mounted body 1 is existing technology. It can be a wall-mounted body 1 with only a cold water channel, or it can be a wall-mounted body 1 with both cold and hot water channels, which will not be elaborated here.

[0080] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the present invention.
