Description

A quick-release faucet structure and faucet Technical Field

[0001] This utility model relates to the field of faucet technology, and more specifically, to a quick-release faucet structure and a faucet. Background Technology

[0002] Currently, during the installation of faucets, users or installers usually need to reach under the installation surface (such as the surface of a basin) to tighten the mounting bolts or screws. However, due to the small space and poor lighting under the countertop, installation is inconvenient.

[0003] To address the aforementioned problems, a faucet assembly and its installation method have been designed [Application No.: 201910339685.5; Publication No.: CN110130444A]. The assembly includes a base, a screw mounted on the base, the screw's shank extending through the base, a mounting plate, the screw being threadedly connected to the mounting plate, wherein the base contacts the top surface of the countertop to be installed, and the mounting plate contacts the bottom surface of the countertop to be installed, and a faucet, the faucet being fixedly mounted on the base, and the faucet's inlet pipe extending through the base to connect to the water inlet line.

[0004] When installing the faucet assembly described above, the screws must first be passed through the base and threaded onto the mounting plate. Then, the mounting plate is passed through the mounting surface and positioned on the bottom surface of the mounting surface. Next, the screws are rotated to raise the mounting plate, which is then clamped to both sides of the mounting surface with the base. Finally, the faucet is fixed to the base. However, the mounting plate is not easy to pass through the mounting holes in the mounting surface, and rotating the screws does not raise the mounting plate. The installer needs to use tools or reach under the mounting surface to support the mounting plate, so that the mounting plate touches the bottom surface of the mounting surface, and then rotate the screws to lock it in place. The operation is still not convenient enough. Utility Model Content

[0005] To address at least one of the aforementioned problems, this utility model provides a quick-release faucet structure suitable for mounting on a faucet body. The faucet body is adapted to be mounted and dismounted from a mounting surface via the quick-release structure. The mounting surface has a mounting through hole. The quick-release structure includes a mounting tube rotatably connected to the faucet body. The lower part of the mounting tube extends beyond the bottom of the faucet body. A limiting component is provided at the lower part of the mounting tube. The limiting component includes a limiting sleeve and an expandable / retractable limiting block. The limiting sleeve is threaded onto the mounting tube, and the limiting block is movably mounted on the limiting sleeve. A retracting component is provided on the mounting tube for pushing and retracting the limiting block. A water inlet pipe is provided at the lower end of the faucet body, and the water inlet pipe is positioned within the limiting sleeve. The mounting tube is positioned to restrict the rotation of the limiting sleeve. During installation, the mounting tube drives the limiting sleeve and the retracting component to pass through the mounting through hole from top to bottom. An external force rotates the mounting tube in the forward direction, causing the limiting sleeve to detach upward from the retracting component, so that the limiting block unfolds and abuts against the lower side of the mounting platform for fixation. During disassembly, an external force rotates the mounting tube in the reverse direction, causing the limiting sleeve to move downward towards the retracting component. The retracting component pushes and retracts the limiting block, allowing the mounting tube, the limiting sleeve, and the retracting component to be removed upward from the mounting through hole. This invention uses forward rotation of the mounting tube to drive the limiting block of the limiting sleeve to abut against the lower side of the mounting platform for fixation. Reverse rotation of the mounting tube causes the retracting component to retract the limiting block, allowing the faucet to be removed from the mounting platform, making disassembly and assembly convenient and quick.

[0006] Optionally, the inner side of the limiting sleeve is provided with an internal thread, the mounting tube is provided with an external thread corresponding to the internal thread, the limiting block is hinged to the limiting sleeve, the retracting component is located on the lower side of the limiting sleeve, and the limiting block is pushed upward by the retracting component to make the limiting block rotate and retract.

[0007] Optionally, when the limiting block disengages from the retracting component, the limiting block rotates and unfolds under its own gravity.

[0008] Optionally, the limiting block is provided with a first limiting part, and the limiting sleeve is provided with a second limiting part corresponding to the first limiting part. When the limiting block is in the unfolded state, the first limiting part and the second limiting part abut against each other to limit the movement.

[0009] Optionally, the retracting component includes a mounting ring and a protrusion disposed on the mounting ring, through which the limiting block is pushed and retracted.

[0010] Optionally, two limiting blocks and two protrusions are symmetrically arranged, and the limiting blocks and protrusions are arranged in a one-to-one correspondence.

[0011] Optionally, the mounting tube is provided with an annular mounting groove, the mounting ring is sleeved in the annular mounting groove, the mounting ring is provided with a through groove for installing the mounting tube, and the mounting ring is provided with a snap-fit ​​for engaging the mounting tube into the through groove.

[0012] Optionally, the diameter of the retracting component is smaller than the diameter of the mounting through hole. When the limiting block retracts, the diameter of the limiting component is smaller than the diameter of the mounting through hole; when the limiting block unfolds, the diameter of the limiting component is larger than the diameter of the mounting through hole.

[0013] Optionally, the faucet body is provided with a manually rotatable rotating sleeve, which is connected to the mounting pipe and rotates synchronously.

[0014] Compared to existing technologies, the quick-release faucet structure of this invention uses a forward-rotating mounting tube to drive the limiting block of the limiting sleeve to abut against the lower side of the mounting surface for fixation; a reverse-rotating mounting tube causes the retracting component to retract the limiting block, allowing the faucet to be removed from the mounting surface, making disassembly and assembly convenient and quick; when the limiting sleeve moves upward and detaches from the retracting component, the limiting block can automatically unfold under its own gravity, eliminating the need for manual unfolding operation, so that the unfolded limiting block can be pressed against the mounting surface to complete the faucet's fixation during subsequent installation, making the operation more convenient; two limiting blocks are symmetrically arranged, and the two symmetrical limiting blocks are pressed against the mounting surface during installation for a more stable faucet installation.

[0015] In addition, this utility model also provides a faucet, including the above-mentioned quick-release faucet structure. This faucet also has the same beneficial effects as the above-mentioned quick-release faucet structure, which will not be described in detail here. Attached Figure Description

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0027] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] Referring to Figures 1-8, this embodiment of the utility model provides a quick-release faucet structure suitable for installation on a faucet body 1. The faucet body 1 is adapted to be installed and disassembled with a mounting surface 2 via the quick-release faucet structure. The mounting surface 2 is provided with a mounting through hole 21. The quick-release faucet structure includes an installation tube 3 rotatably connected to the faucet body 1. The lower part of the installation tube 3 extends out of the bottom of the faucet body 1. A limiting component is provided at the lower part of the installation tube 3. The limiting component includes a limiting sleeve 4 and an expandable / retractable limiting block 41. The limiting sleeve 4 is threaded onto the installation tube 3, and the limiting block 41 is movably disposed on the limiting sleeve 4. A retracting component 5 is provided on the installation tube 3 for pushing and retracting the limiting block 41. A water inlet pipe 10 is provided at the lower end of the faucet body 1. The water inlet pipe 10 is a flexible hose used to connect to an external water passage. The water inlet pipe 10 is placed... One side of the limiting sleeve 4 restricts its rotation. During installation, the mounting tube 3 drives the limiting sleeve 4 and the retracting component 5 to pass through the mounting through hole 21 from top to bottom. An external force rotates the mounting tube 3 in the forward direction, causing the limiting sleeve 4 to detach upward from the retracting component 5, so that the limiting block 41 unfolds and abuts against the lower side of the mounting platform 2 for fixation. During disassembly, an external force rotates the mounting tube 3 in the reverse direction, causing the limiting sleeve 4 to move downward towards the retracting component 5. The retracting component 5 pushes and retracts the limiting block 41, so that the mounting tube 3, the limiting sleeve 4, and the retracting component 5 can be removed upward from the mounting through hole 21. The forward and reverse directions are opposite. This utility model uses the forward rotation of the mounting tube to drive the limiting block of the limiting sleeve to abut against the lower side of the mounting platform for fixation. By rotating the mounting tube in the reverse direction, the retracting component retracts the limiting block, so that the faucet can be removed from the mounting platform. The disassembly and assembly are convenient and quick.

[0029] Referring to Figures 1, 2, and 4, the inner side of the limiting sleeve 4 is provided with an internal thread 42, and the mounting tube 3 is provided with an external thread 31 corresponding to the internal thread 42. Since the water inlet pipe 10 limits the rotation of the limiting sleeve 4, when the mounting tube 3 is rotated, the limiting sleeve 4 can only move along the axial direction of the mounting tube 3. The retracting component 5 is located on the lower side of the limiting sleeve 4. During installation, rotating the mounting tube 3 in the forward direction moves the limiting sleeve 4 upward, so that the limiting block 41 of the limiting sleeve 4 presses against the mounting platform to complete the fixed installation. During disassembly, rotating the mounting tube 3 in the reverse direction moves the limiting sleeve 4 downward, and the retracting component 5 below retracts the limiting block 41. After retraction, the limiting block 41 can pass through the mounting through hole 21, allowing the faucet to be easily removed. The limiting block 41 is hinged to the limiting sleeve 4. The limiting block 41 is pushed upward by the retracting component 5 to rotate and retract. The limiting block 41 and the limiting sleeve 4 are hinged with a hinge axis. When the limiting block 41 rotates upward and retracts, in the horizontal direction, the center of gravity of the limiting block 41 is located on the side away from the hinge axis from the mounting tube 3. When the limiting block 41 is disengaged from the retracting component 5, the limiting block 41 rotates and unfolds under its own weight. When the limiting sleeve 4 moves upward and disengages from the retracting component 5, the limiting block 41 can automatically unfold under its own weight without manual unfolding operation. This makes it easier to fix the unfolded limiting block 41 against the mounting surface to complete the fixed installation of the faucet during subsequent installation.

[0030] Referring to Figures 2, 4, and 5, the limiting block 41 is provided with a first limiting part 411, and the limiting sleeve 4 is provided with a second limiting part 43 corresponding to the first limiting part 411. When the limiting block 41 is in the unfolded state, the first limiting part 411 and the second limiting part 43 abut against each other to limit the limiting block 41, so that the limiting block 41 maintains its unfolded state. The retracting component 5 includes a mounting ring 51 and a protrusion 52 provided on the mounting ring 51. The protrusion 52 protrudes upward and is integrally formed with the mounting ring 51. The protrusion 52 pushes and retracts the limiting block 41. There are two symmetrically arranged limiting blocks 41. During installation, the two symmetrical limiting blocks 41 are pressed against the mounting surface for a more stable installation, making the faucet installation more secure. There are two symmetrically arranged protrusions 52. Each limiting block 41 and protrusion 52 are configured in a one-to-one correspondence; the mounting pipe 3 is provided with an annular mounting groove 32, and the mounting ring 51 is fitted into the annular mounting groove 32. The mounting ring 51 is provided with a through groove 53 for installing the mounting pipe 3, and a retaining slot 54 for inserting the mounting pipe 3 into the through groove 53. The mounting ring 51 is an annular component, and it is inserted into the mounting pipe 3 through the retaining slot 54, which is convenient for assembly; the mounting ring 51 is made of plastic or metal with good toughness so that it can be elastically deformed during assembly; the mounting ring 51 is rotatably installed in the annular mounting groove 32, and the water inlet pipe is located on one side of the mounting ring 51. The rotation of the mounting ring 51 is restricted by the water inlet pipe so that when the limiting sleeve 4 moves down, it can be aligned with the limiting block 41 through the protrusion 52.

[0031] Referring to Figures 1, 5, and 6, the diameter of the retractable component 5 is smaller than the diameter of the mounting through hole 21. When the limiting block 41 retracts, the diameter of the limiting component is smaller than the diameter of the mounting through hole 21, so that the limiting component can pass through the mounting through hole from top to bottom during installation and from bottom to top during disassembly. When the limiting block 41 unfolds, the diameter of the limiting component is larger than the diameter of the mounting through hole 21, preventing the limiting block 41 from coming out of the mounting through hole 21 during installation, so that the limiting block 41 can be fixed by pressing against the mounting platform upwards during installation.

[0032] Referring to Figures 1-3, a manually rotatable rotating sleeve 6 is provided on the faucet body 1. The rotating sleeve 6 is connected to the installation tube 3 and rotates synchronously. The rotating sleeve 6 is exposed outside the faucet body 1. An anti-slip groove 61 is provided on the side wall of the rotating sleeve 6 so that the installer can rotate the rotating sleeve 6 by hand to disassemble and install the faucet. In this embodiment, the anti-slip groove 61 is a knurled groove.

[0033] The quick-release faucet structure of this utility model uses forward rotation of the mounting tube to drive the limiting block of the limiting sleeve to abut against the lower side of the mounting surface for fixation; reverse rotation of the mounting tube causes the retracting component to retract the limiting block, allowing the faucet to be removed from the mounting surface, making disassembly and assembly convenient and quick; when the limiting sleeve moves upward and detaches from the retracting component, the limiting block can automatically unfold under its own gravity, eliminating the need for manual unfolding operation, so that the unfolded limiting block can be pressed against the mounting surface to complete the faucet fixation during subsequent installation, making the operation more convenient; two limiting blocks are symmetrically arranged, and the two symmetrical limiting blocks are pressed against the mounting surface during installation for a more stable faucet installation.

[0034] In addition, this utility model also provides a faucet, including the above-mentioned quick-release faucet structure. This faucet also has the same beneficial effects as the above-mentioned quick-release faucet structure, which will not be described in detail here.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
