Abstract

The application discloses a mounting structure and method of a water outlet device, the water outlet device and a bathtub. The mounting structure is matched with a mounting carrier which is provided with a mounting hole penetrating through a support surface of the mounting carrier and used for mounting the water outlet device. The mounting structure comprises a first limiting piece, a second limiting piece and at least one clamping piece. The first limiting piece is arranged at the bottom of the outer side surface of the body of the water outlet device and abuts against the support surface. The second limiting piece is connected to the support surface and is close to the mounting hole. The clamping piece is clamped to the second limiting piece by moving in the direction of the body laterally inward, and the clamping piece clamps the first limiting piece, so that the second limiting piece limits the movement freedom degree of the clamping piece in the axial direction of the mounting hole, and the clamping piece limits the movement freedom degree of the first limiting piece in the axial direction of the mounting hole, thereby limiting the dismounting of the body from the support surface. In the case that the positions of the first limiting piece, the second limiting piece and the clamping piece are matched, the faucet can be quickly mounted on the support surface by laterally pushing the clamping piece, and the mounting is very convenient.

Description

Technical Field

[0001] This invention relates to the field of bathroom fixtures, and in particular to an installation structure and method for a water outlet device, a water outlet device, and a bathtub. Background Technology

[0002] Traditionally, faucets are installed under a countertop, which can be a washbasin or a bathtub. Specifically, the common under-counter installation method involves securing the faucet body to the bottom of the countertop with a nut. This method is relatively simple for washbasins, but for bathtubs, replacing or repairing the faucet requires opening the entire tub and threading it from inside, which is complex, difficult, and prone to rusting, thread jamming, and other problems over time. To address these issues, several faucets have been developed for countertop installation. The simplest method uses self-tapping screws to secure the faucet body to the countertop. However, this method has several drawbacks: after repeated disassembly and reassembly, the screw threads on the countertop wear down, making re-tightening impossible; if machine screws are used, a machine screw nut or other threaded structure is required, which needs to be pre-embedded in the bathtub surface or glued to the appropriate position; if the nut's position is misaligned (not perpendicular to the countertop), the machine screw may not tighten properly. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing an installation structure and method for a water outlet device, a water outlet device, and a bathtub, which makes the installation of the water outlet device more convenient.

[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: an installation structure for a water outlet device, which cooperates with an installation carrier. The installation carrier has an installation hole that penetrates its support surface and is used to install the water outlet device. It includes a first limiting member, a second limiting member, and at least one locking member. The first limiting member is disposed at the bottom of the outer side of the body of the water outlet device and abuts against the support surface. The second limiting member is connected to the support surface and is close to the installation hole. The locking member moves inward along the side of the body to lock onto the second limiting member and lock onto the first limiting member, so that the second limiting member restricts the degree of freedom of movement of the locking member in the axial direction of the installation hole, while the locking member restricts the degree of freedom of movement of the first limiting member in the axial direction of the installation hole, thereby restricting the body from being disassembled from the support surface.

[0005] Furthermore, the locking element disengages from the second and first limiting members by moving laterally outward along the body, thereby allowing the body to be detached from the support surface.

[0006] Furthermore, it also includes a decorative cover that is fitted over the body and covers the card, the first limiting member, and the second limiting member, and restricts the card from moving laterally outward along the body.

[0007] Furthermore, the second limiting member includes a plurality of fasteners spaced circumferentially along the mounting hole, each fastener being connected to the support surface; the first limiting member includes an upper shoulder and a lower shoulder spaced vertically, the upper shoulder and the lower shoulder extending circumferentially along the body, and the upper shoulder having a first clearance notch at the position corresponding to each fastener, and the lower shoulder having a second clearance notch at the position corresponding to each fastener; the lower shoulder abuts against the support surface, the locking member is engaged with the fastener, and partially adapted to be engaged in the gap between the upper shoulder and the lower shoulder.

[0008] Furthermore, the fastener is threadedly connected to the mounting carrier; the fastener has a double-shoulder structure, which includes an upper shoulder and a lower shoulder, the upper shoulder and the lower shoulder being spaced apart vertically, the lower shoulder abutting against the support surface, and the clip partially fitting into the gap between the upper shoulder and the lower shoulder.

[0009] Furthermore, the fastener is a double-shoulder screw and a self-tapping screw.

[0010] Furthermore, the diameter of the upper shoulder is smaller than the diameter of the lower shoulder, the first clearance notch of the upper shoulder is smaller than the second clearance notch of the lower shoulder, and one end of the first clearance notch of the upper shoulder is vertically aligned with one end of the second clearance notch of the lower shoulder, while the other end of the first clearance notch of the upper shoulder is vertically offset from the other end of the second clearance notch of the lower shoulder.

[0011] Furthermore, the side of the upper shoulder abuts against one end of the clearance notch of the upper shoulder, and / or, the side of the lower shoulder abuts against one end of the clearance notch of the lower shoulder.

[0012] Furthermore, the locking element is arc-shaped, with its inner edge fitting into the gap between the upper and lower locking shoulders; the locking element has a through-groove groove corresponding to the fastener it mates with, the groove opening being located on the inner side of the locking element, the groove including a clearance section and a locking section that are interconnected, the clearance section being used to avoid the fastener, and the locking section forming a locking engagement with the fastener.

[0013] Furthermore, the central angle of the card is less than or equal to 180°, and the card engages with at least two fasteners; the bottom of the card is provided with a support platform that abuts against the support surface.

[0014] Furthermore, a clamping structure is provided between the clip and the decorative cover. The clamping structure includes a clamping groove and a clamping protrusion that engage with each other. One of the clamping groove and the clamping protrusion is located on the outer side of the clip, and the other is located on the inner side of the decorative cover.

[0015] The present invention also provides a method for installing a water outlet device, which adopts the installation structure of the water outlet device as described above, and includes the following steps:

[0016] A second limiting component is connected to the support surface of the mounting carrier;

[0017] Align the bottom of the water outlet device with the mounting hole on the support surface, and make the first limiting member abut against the support surface;

[0018] Push the locking piece inward along the side of the water outlet device to lock it into the second limiting piece and lock it into the first limiting piece.

[0019] The present invention also provides a water outlet device, including a body and an installation structure for the water outlet device as described above.

[0020] Furthermore, the main body includes a valve body and a water outlet housing that are separate from each other. The valve body is equipped with a valve core, and the water outlet of the valve core is connected to the water outlet housing. The bottom of the outer side of the valve body and the water outlet housing are respectively provided with the first limiting member, so that the valve body and the water outlet housing are respectively installed through the mounting structure. Alternatively, the main body is a faucet body with a water outlet and a valve core. Alternatively, the main body is a shower head holder for placing the shower head body. The main body is fitted with a sealing ring that seals with the mounting hole.

[0021] The present invention also provides a bathtub, including a tub body and at least one water outlet device as described above, wherein the support surface is disposed on the tub body.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Since the installation structure of the present invention includes the first limiting member, the second limiting member, and the locking member, when the positions of the first limiting member, the second limiting member, and the locking member are matched, the water outlet device can be conveniently installed on the support surface by simply pushing the locking member laterally.

[0024] 2. The locking component disengages from the second and first limiting components by moving laterally outward along the body. Therefore, when it is necessary to disassemble the water outlet device, it can be easily disassembled by pulling the locking component laterally. Thus, the present invention enables repeated assembly and disassembly.

[0025] 3. The decorative cover not only makes the overall structure simpler and more beautiful, but also limits the locking parts and improves the stability of the faucet in the installation state.

[0026] 4. The second limiting component includes multiple fasteners spaced circumferentially along the mounting hole. The first limiting component includes upper and lower shoulders spaced vertically, simplifying the structure of both components and allowing for precise design of the fit between the fasteners and the first limiting component, thereby further improving the stability of the faucet after installation. The fasteners are fixed to the support surface via threaded connections, making fastener fixing more convenient and secure. In particular, the fasteners have a double-shoulder structure, allowing for precise design of the fit between them and the fasteners, further enhancing the stability of the faucet after installation.

[0027] 5. The locking element is arc-shaped, and its inner edge is locked between the upper and lower locking shoulders, making the locking element fit more tightly with the first limiting element and the contact surface larger, thereby further improving the stability of the water outlet device after installation.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the installation structure and method of the water outlet device, the water outlet device and the bathtub of the present invention are not limited to the embodiments.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0054] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" refers to two or more. In the description of this invention, unless otherwise explicitly specified and limited, terms such as "setup" and "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0055] Please see Figures 1-22As shown in the figure, an embodiment of the present invention provides a bathtub, including a tub body 1 and at least one water outlet device. The supporting surface 11 of the tub body 1 is provided with a mounting hole 111 for installing the water outlet device, and a skirt 12 is provided around the tub body 1. The water outlet device includes a body and its mounting structure. The mounting structure cooperates with a mounting carrier for the water outlet device, and the mounting carrier is provided with a mounting hole 111 penetrating its supporting surface 11. In this embodiment, the mounting carrier is the tub body 1, and the top surface of the tub body constitutes the supporting surface 11. The mounting structure includes a first limiting member, a second limiting member, and at least one locking member 6. The first limiting member is disposed at the bottom of the outer side of the body and abuts against the supporting surface 11. The second limiting member is connected to the supporting surface 11 from above and is close to the mounting hole 111. When installing the water outlet device, the locking piece 6 moves inward along the side of the faucet body and engages with the second limiting piece, thus locking the first limiting piece. The second limiting piece restricts the axial (vertical) movement of the locking piece 6 within the mounting hole 111, while the locking piece 6 restricts the axial (vertical) movement of the first limiting piece within the mounting hole 111, thereby preventing the main body from being disassembled from the support surface 11. When disassembling the water outlet device, the locking piece 6 moves outward along the side of the main body and disengages from the first and second limiting pieces, allowing the main body of the water outlet device to be disassembled from the support surface 11.

[0056] In this embodiment, there are two water outlet devices, one of which is a faucet and the other is a shower head, but this is not a limitation. For the faucet, in this embodiment, the main body includes a valve body 2 and a water outlet housing 3, which are separate from each other. The valve body 2 is equipped with a valve core 5, and the outlet of the valve core 5 is connected to the water outlet housing 3 via a water pipe. The bottom of the outer sides of the valve body 2 and the water outlet housing 3 are respectively provided with the first limiting member, so that the valve body 2 and the water outlet housing 3 can be installed using the above-described mounting structure. In other embodiments, for the faucet, the main body is a faucet body with a water outlet and a valve core. For the shower head, the main body is a shower head seat (in the figure, the shower head seat and its first limiting member are covered by the decorative cover and the shower head body 10 described below). When the shower head body 10 is not pulled out for use, the shower head body 10 is located on the shower head seat; the shower head seat is installed using the above-described mounting structure. The following description of the installation structure mainly uses the valve body 2 as an example, combined with the accompanying drawings.

[0057] The mounting structure of the present invention also includes a decorative cover 8, which is fitted over the bottom of the main body (i.e., valve body 2 / water outlet housing 3 / shower head seat), and the decorative cover 8 covers the locking member 6, the first limiting member and the second limiting member, and restricts the locking member 6 from moving outward along the side of the main body.

[0058] The second limiting member includes a plurality of fasteners distributed circumferentially along the mounting hole 111. Each fastener is connected to the support surface 11. Specifically, each fastener is threaded to the mounting carrier (i.e., cylinder 1), but is not limited thereto. In other embodiments, each fastener is connected to the support surface 11 by adhesive bonding or other fixing methods.

[0059] Each fastener has a double-shoulder structure, which includes an upper shoulder 71 and a lower shoulder 72, with the upper shoulder 71 and lower shoulder 72 spaced apart vertically. In this embodiment, each fastener is a double-shoulder screw 7, and it is a self-tapping screw, such as... Figure 6 , Figure 7 As shown, the fastener (i.e., the double-shoulder screw 7) also includes a threaded section 73 located below the lower shoulder 72, which is threadedly connected to the support surface 11. The diameter d2 of the upper shoulder 71 is smaller than the diameter d3 of the lower shoulder 72, and the lower shoulder 72 abuts against the support surface 11, thus limiting the downward movement of the double-shoulder screw 7. The top surface of the upper shoulder 71 is provided with a cross-shaped groove for installing the double-shoulder screw 7; the cross-shaped groove can be replaced by a slotted groove or the like. The retainer 6 is engaged with at least one fastener, that is, the retainer 6 is partially fitted into the gap between the upper shoulder 71 and the lower shoulder 72. In other embodiments, the fastener is a single-shoulder self-tapping screw, in which case the self-tapping screw part extends into the support surface 11, and there is a certain gap between the head of the self-tapping screw and the support surface; the retainer 6 is partially fitted into the gap between the head of the self-tapping screw and the support surface 11.

[0060] like Figures 8-11 As shown, the first limiting member includes an upper shoulder 21 and a lower shoulder 22 distributed at intervals. The upper shoulder 21 and the lower shoulder 22 extend circumferentially along the body (i.e., valve body 2 / water outlet housing 3 / shower seat) to form an annular structure. They are respectively provided with a first clearance notch 211 and a second clearance notch 221 corresponding to each fastener (i.e., double shoulder screw 7). The first clearance notch 211 of the upper shoulder 21 is smaller than the second clearance notch 221 of the lower shoulder 22. One end of the first clearance notch 211 of the upper shoulder 21 is vertically aligned with one end of the clearance notch 221 of the lower shoulder 22. The other end of the first clearance notch 211 of the upper shoulder 21 is vertically offset from the other end of the second clearance notch 221 of the lower shoulder 22. The side of the upper shoulder 71 of the double-shoulder screw 7 abuts against one end of the first clearance notch 211 of the upper shoulder 21, and / or the side of the lower shoulder 72 abuts against one end of the second clearance notch 221 of the lower shoulder 22, thereby restricting the rotation of the body. The lower shoulder 22 abuts against the support surface 11, and the locking piece 6 partially fits into the gap between the upper shoulder 21 and the lower shoulder 22. The diameter CD2 of the upper shoulder 21 ≥ the diameter CD3 of the lower shoulder 22 > the diameter CD1 of the gap between the upper shoulder 21 and the lower shoulder 22.

[0061] like Figures 12-15As shown, the clip 6 is arc-shaped, and its inner edge 61 (i.e., the inner edge of the clip 6) fits into the gap between the upper shoulder 21 and the lower shoulder 22. The clip 6 has a slot 62 for engaging with the fastener (i.e., the double-shoulder screw 7) corresponding to it. The slot 62 is vertically continuous, and the opening of the slot 62 is located on the inner side of the clip 6. The slot 62 includes a clearance section 621 and a locking section 622 that are distributed sequentially and interconnected from its opening in a general direction around the clip. The clearance section 621 is used to avoid the fastener, and the locking section 622 forms a locking engagement with the fastener. Specifically, the dimensions of the slot 62 and the diameter of the double-shoulder screw 7 are related as follows: d1 ≤ 2 times D1 < d2 < 2 times D2 < d3 < 2 times D3 (D1, D2 and D3 in the attached figure refer to radii), where d1 is the diameter of the cylindrical portion of the double-shoulder screw 7 located between its upper shoulder 71 and lower shoulder 72, d2 is the diameter of the upper shoulder 71 of the double-shoulder screw 7, d3 is the diameter of the lower shoulder 72 of the double-shoulder screw 7, D1 is the radius of the locking section 622, D2 is the radius of the yielding section 621, and D3 is the radius of both ends of the support platform 63 described below. The relationship between the first clearance notch 211 of the upper shoulder 21, the second clearance notch 221 of the lower shoulder 22, and the diameter of the double shoulder screw 7 is as follows: d1 < d2 < 2 times C1 < d3 < 2 times C2, where C1 is the radius of the first clearance notch 211 of the upper shoulder 21, and C2 is the radius of the second clearance notch 221 of the lower shoulder 22.

[0062] In this embodiment, the central angle of the clip 6 is less than or equal to 180°. The clip 6 mates with at least two fasteners, specifically, with two fasteners (i.e., double-shoulder screws 7), and the two double-shoulder screws 7 are respectively located near both ends of the clip 6. Therefore, the clip 6 has two slots 62, which are respectively located near both ends of the clip 6. The bottom of the clip 6 has a support platform 63, which abuts against the support surface 11. The support platform 63 is also arc-shaped, and its length is less than the length of the clip 6. Specifically, the support platform 63 is located between the two slots 62 of the clip 6. The radius DB2 of the inner contour of the support platform 63 is less than the radius DB3 of the outer contour of the clip 6, but greater than the radius DB1 of the inner contour of the clip 6. The outer contour of the support platform 63 coincides with the outer contour of the clip 6, so that the inner edge 61 of the clip 6 is not covered by the support platform 63.

[0063] The thickness relationship of the clip 6, the first limiting member, and the second limiting member is: L1 = h1 + h2 = H1 + H2, L2 ≤ h2 = H2, where L1 is the total thickness of the clip 6 at the location of the support platform 63, L2 is the thickness of the inner edge 61 and the slot 62 of the clip 6, h1 is the thickness of the lower shoulder 22, h2 is the distance between the bottom surface of the upper shoulder 21 and the upper surface of the lower shoulder 22, H1 is the thickness of the lower shoulder 72 of the double-shoulder screw 7, and H2 is the distance between the bottom surface of the upper shoulder 71 and the upper surface of the lower shoulder 72. In this embodiment, the number of clips 6 is one, but it is not limited to this. In other embodiments, the number of clips 6 is multiple, such as two. Preferably, the inner edges 61 at both ends of the clip 6 are engaged between the upper shoulder 21 and the lower shoulder 22 of the first limiting member.

[0064] A clamping structure is provided between the clip 6 and the decorative cover 8 to laterally clamp the clip 6 and also limit the position of the decorative cover 8. This clamping structure includes a clamping groove 64 and a clamping protrusion 81 that engage with each other. One of the clamping groove 64 and the clamping protrusion 81 is located on the outer side of the clip 6, and the other is located on the inner side of the decorative cover 8. Specifically, in this embodiment, the clamping groove 64 is located on the outer side of the clip 6, such as... Figure 12 As shown in Figure 13, the tightening protrusion 81 is located on the inner side of the decorative cover 8, and the tightening protrusion 81 is an arc-shaped protrusion, as shown in Figure 13. Figure 15 As shown.

[0065] A sealing ring 9 is fitted at the bottom of the main body (i.e., valve body 2 / or water outlet housing 3 / shower head seat), which seals against the inner surface of the mounting hole 111. Specifically, as shown... Figure 9 As shown, the bottom of the main body (taking valve body 2 as an example) is provided with a receiving groove 23 extending circumferentially. The opening of the receiving groove 23 faces downward, and the sealing ring 9 is installed in the receiving groove 23. The receiving groove 23 achieves axial and radial limiting of the sealing ring 9. The sealing ring 9 is preferably a tapered sealing ring that is wider at the top and narrower at the bottom, which can be compressed in the vertical direction to form a certain pre-tightening force, so as to achieve tight limiting of valve body 2 / water outlet body 3 in the vertical and radial directions.

[0066] The installation method of the water outlet device of the present invention includes the following steps:

[0067] A second limiting member is connected at a designated position on the edge of the mounting hole 111 on the support surface 11;

[0068] Align the bottom of the main body with the mounting hole 111 and insert it downward into the mounting hole 111 of the support surface 11, and make the first limiting member abut against the support surface 11;

[0069] Push the locking piece 6 inward along the side of the body so that the locking piece 6 is locked onto the second limiting piece and locks onto the first limiting piece.

[0070] The following describes the detailed steps of the above installation method using valve body 2 as an example, in conjunction with the accompanying drawings:

[0071] Secure each fastener (i.e., double-shoulder screw 7) at the designated position on the edge of the mounting hole 111 on the support surface 11, such as Figure 16 , Figure 17 As shown;

[0072] Align the bottom of the valve body 2, which contains the valve core 5, with the mounting hole 111 and insert it downwards into the mounting hole 111 until its lower shoulder 22 abuts against the support surface 11, and the upper shoulder 21 and lower shoulder 22 respectively avoid the double shoulder screw 7 through their clearance notches. Figure 18 As shown;

[0073] Align each slot 62 of the clip 6 with the corresponding fastener (i.e., the double-shoulder screw 7), and slip it over the fastener (i.e., the double-shoulder screw 7) from top to bottom, so that each fastener (i.e., the double-shoulder screw 7) enters the clearance section 621 of the slot 62, as follows. Figure 19 As shown;

[0074] Push the retaining member 6 inward along the side of the valve body 2, so that each fastener (i.e., the double-shoulder screw 7) enters the retaining section 622 of the two retaining slots 62 of the retaining member 6, thereby achieving a tight fit between the retaining member 6 and the fastener. That is, the part where the retaining section 622 is located is locked in the gap between the upper shoulder 71 and the lower shoulder 72 of the double-shoulder screw 7. At the same time, the inner edge 61 of the retaining member 6 is locked in the gap between the upper shoulder 21 and the lower shoulder 22 of the valve body 2. Figure 20 As shown; at this time, the valve body 2 is limited in the vertical direction, and the sealing ring 9 is compressed, thereby securing the valve body 2 in the vertical direction;

[0075] The decorative cover 8 is placed over the valve body 2, and the tightening protrusion 81 is aligned with the tightening groove 64 on the retaining piece 6. The decorative cover 8 is then pressed down, so that it covers the retaining piece 6, the double-shoulder screw 7, the upper shoulder 21, and the lower shoulder 22. The tightening protrusion 81 holds the outer side of the retaining piece 6, preventing it from moving outwards along the side of the valve body 2. Figure 21 , Figure 22 As shown ( Figure 21 In the middle, a decorative shell 24 is fitted over the valve body 2 to securely install the valve body 2. After the valve body 2 is installed, the operating handle 4 can be connected to the top of the valve core 5.

[0076] When it is necessary to disassemble the valve body 2, simply reverse the steps described above, as follows: First, lift the decorative cover 8 upwards to expose the retaining clip 6, the double shoulder screw 7, the upper shoulder 21, and the lower shoulder 22; then push the retaining clip 6 outwards along the side of the valve body 2, so that the inner edge 61 of the retaining clip 6 exits the gap between the upper shoulder 21 and the lower shoulder 22, and also so that the double shoulder screw 7 moves from the retaining section 622 of the retaining clip 6 to the disengaging section 621; then, lift the retaining clip 6 to disengage it from the double shoulder screw 7; finally, pull the valve body 2 upwards out of the mounting hole 111, thus completing the disassembly of the valve body 2.

[0077] The steps for assembling and disassembling the faucet's outlet housing 3 and the shower head seat are the same as or basically the same as those for assembling and disassembling the valve body 2, and will not be repeated here.

[0078] This invention enables the water outlet device to be quickly installed and removed on the support surface 11, and allows for repeated installation and removal without damage. When the water outlet device is used in a bathtub, it does not need to be inserted into the tub (i.e., the space between the tub body 1 and the skirt 12) for installation and removal, reducing the need for the bathtub to tip over.
