Description

Technical Field

[0001] The present invention relates to the technical field of sanitary ware products, and more particularly, to a quick disassembly and assembly structure for a faucet and a faucet. Background Art

[0002] At present, most of the installation methods of faucets on the market are under-counter installation. For example, a faucet fixing seat, a faucet and a washbasin disclosed in Chinese Patent CN210216593U include a connecting member. The connecting member includes a main body and a connecting portion. The main body is provided with a guiding hole, and the connecting portion is connected to the main body. The connecting portion is provided with an installation hole; and an extension member is connected to the main body. The extension member is provided with a through hole, and the through hole communicates with the guiding hole to form a receiving hole. In this application, installation operations need to be carried out under the workbench to fix the faucet on the workbench.

[0003] Due to the influence of multiple factors such as the washbasin and the use environment, the installation operation space under the workbench is narrow, resulting in time-consuming and laborious installation and a very poor user experience. Summary of the Invention

[0004] The present invention discloses a quick disassembly and assembly structure for a faucet, aiming to improve the problem of time-consuming and laborious installation of the faucet under the workbench.

[0005] The present invention adopts the following solutions:

[0006] A quick disassembly and assembly structure for a faucet includes a threaded pipe and a locking assembly. One end of the threaded pipe is disposed below the workbench for connecting with the locking assembly, and the other end is located above the workbench for adjusting the locking assembly;

[0007] The locking assembly has a moving member adapted to the threaded pipe. At least one cantilever is mounted on the moving member, and the cantilever has two states: unfolded and retracted;

[0008] A guide sleeve is further disposed on the threaded pipe. By operably rotating the threaded pipe, the moving member can move up and down along the axis of the threaded pipe to approach or move away from the guide sleeve. Among them, the cantilever is configured to retract when approaching the guide sleeve and unfold when moving away from the guide sleeve; and the size of the cantilever when unfolded is larger than the size of the installation hole of the workbench.

[0009] As a further improvement, a limiting member is further included to limit the rotation of the moving member along with the threaded pipe, so that the circular motion of the threaded pipe is converted into the linear motion of the moving member.

[0010] As a further improvement, one end of the cantilever is hinged to the moving member, and the size of the other end is larger than that of the hinged end, so that the cantilever automatically unfolds under the action of gravity when it is away from the guide sleeve.

[0011] As a further improvement, the cantilever is T-shaped, and two are symmetrically arranged along the moving member.

[0012] As a further improvement, a triggering portion is provided at the position of the guide sleeve corresponding to the cantilever for triggering the folding of the cantilever.

[0013] As a further improvement, an anti-loosening nut is installed below the guide sleeve, and the guide sleeve is limited in cooperation with the anti-loosening nut.

[0014] Another faucet is provided, including a faucet body and a quick disassembly and assembly structure for fixing the faucet body, and the quick disassembly and assembly structure is the quick disassembly and assembly structure for the faucet as described above.

[0015] As a further improvement, the faucet body has a fixing portion and a spout portion. The fixing portion and the spout portion are connected by a connecting member. The threaded pipe passes through the fixing portion and is adaptively connected to the connecting member. By driving the connecting member to rotate, the threaded pipe rotates itself.

[0016] As a further improvement, a connecting sleeve is provided on the connecting member, and a tooth portion is provided along the axial direction of the connecting sleeve. The spout portion is limited by the connecting sleeve to the fixing portion.

[0017] As a further improvement, a pull-out pipe connected to the faucet body is further included, and the pull-out pipe passes through the threaded pipe.

[0018] By adopting the above technical solutions, the following technical effects can be achieved by the present invention:

[0019] For the quick disassembly and assembly structure for the faucet of the present application, by driving the threaded pipe to rotate on the workbench, the disassembly and assembly of the threaded pipe can be realized, which is convenient and fast. There is no need to work under the workbench to solve the problem that it is time-consuming and laborious to perform installation operations in the narrow space under the workbench. In addition, the quick disassembly and assembly structure can also be applicable to workbenches of different thicknesses, and has high compatibility. Compared with the prior art, the advantages of the present application are obvious. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Embodiment

[0056] Combine Figures 1 to 4, this embodiment provides a quick disassembly and assembly structure for a faucet, including a threaded pipe 1 and a locking assembly 2. One end of the threaded pipe 1 is disposed below the workbench for connecting with the locking assembly 2, and the other end is located above the workbench for adjusting the locking assembly 2. The locking assembly 2 has a moving member 21 adapted to the threaded pipe 1, and at least one cantilever 22 is installed on the moving member 21. The cantilever 22 has two states: expansion and contraction. A guide sleeve 3 is also arranged on the threaded pipe 1. By operably rotating the threaded pipe 1, the moving member 21 can move up and down along the axis of the threaded pipe 1 to approach or move away from the guide sleeve 3. Among them, the cantilever 22 is configured to contract when approaching the guide sleeve 3 and expand when moving away from the guide sleeve 3, and the size of the cantilever 22 when expanded is larger than the size of the mounting hole of the workbench.

[0057] For example, the moving member 21 is sleeved on the threaded pipe 1 and is threadedly connected to the threaded pipe 1. During assembly, the threaded pipe 1 with the locking assembly 2 and the guide sleeve 3 is inserted through the mounting hole of the workbench, so that the end of the threaded pipe 1 with the locking assembly 2 is located below the workbench. At this time, the cantilever 22 is in a contracted state under the action of the guide sleeve 3. The threaded pipe 1 located above the workbench can be adapted to the faucet mounting seat or other components used to connect with the threaded pipe 1. Use a wrench or other tools to rotate the threaded pipe 1. When the threaded pipe 1 rotates, the moving member 21 moves upward along the axis of the threaded pipe 1. When moving away from the guide sleeve 3, the cantilever 22 automatically expands. Continue to drive the threaded pipe 1 to rotate until the cantilever 22 abuts against the workbench, so that the threaded pipe 1 is fastened to the workbench. During disassembly, rotate the threaded pipe 1 in the reverse direction, so that the moving member 21 moves downward along the axis of the threaded pipe 1. When moving close to the guide sleeve 3, under the action of the guide sleeve 3, the cantilever 22 contracts. At this time, the threaded pipe 1, the locking assembly 2 and the guide sleeve 3 can be directly pulled out from the mounting hole, thus completing the disassembly process on the workbench.

[0058] In summary, in this embodiment, by driving the threaded pipe 1 to rotate on the workbench, the disassembly and assembly of the threaded pipe 1 can be realized, which is convenient and fast. There is no need to work under the workbench to solve the difficulties in installation in a narrow space. In addition, it can also be applicable to workbenches of different thicknesses, with high compatibility.

[0059] In another embodiment, a limiting member 4 is further included to limit the rotation of the moving member 21 along with the threaded pipe 1, so that the circular motion of the threaded pipe 1 is converted into the linear motion of the moving member 21. For example, the limiting member 4 is columnar and is fixed to the base on the workbench or other components. A through hole 212 for the limiting member 4 to pass through is provided on the moving member 21, so that when the threaded pipe 1 rotates, the moving member 21 can move up and down along the threaded pipe 1 but does not rotate along with the threaded pipe 1, thereby keeping the relative position between the cantilever 22 and the guide sleeve 3 unchanged.

[0060] Based on the above embodiments, in an alternative embodiment of the present invention, one end of the cantilever 22 is provided with a first shaft hole 211, and the moving member 21 is provided with a second shaft hole 221 corresponding to the first shaft hole 211. The rotating shaft 23 is inserted into the first shaft hole 211 and the second shaft hole 221, so that the cantilever 22 and the moving member 21 are configured to be hinged, and it is not limited thereto. Wherein, the size of the other end of the cantilever 22 is larger than that of the hinged end, so that the cantilever 22 automatically unfolds under the action of gravity when it is away from the guide sleeve 3.

[0061] It should be noted that, in other embodiments, a plurality of cantilevers 22 can be provided, and the cantilevers 22 are arranged along the circumferential direction of the moving member 21. Preferably, in this embodiment, the cantilever 22 is in a T shape, and two are symmetrically arranged along the axis of the moving member 21, so that the forces are balanced when the cantilever 22 abuts against the workbench.

[0062] Preferably, a triggering portion 31 is provided at the position of the guide sleeve 3 corresponding to the cantilever 22 for triggering the folding of the cantilever 22. The triggering portion 31 protrudes upward along the guide sleeve 3. When the moving member 21 drives the cantilever 22 to move upward, the cantilever 22 unfolds after breaking away from the restriction of the triggering portion 31. When the moving member 21 drives the cantilever 22 to move downward, the cantilever 22 continues to move downward after abutting against the triggering portion 31, so that the triggering portion 31 abuts against the cantilever 22 to fold it inward, and the cantilever 22 can be accommodated in the groove formed between the triggering portion 31 and the moving member 21 after being folded.

[0063] In a preferred embodiment, an anti-loosening nut 5 is installed below the guide sleeve 3. The anti-loosening nut 5 is threadedly connected to the threaded tube 1 and can rotate with the threaded tube 1. A clamping portion 33 is provided on the guide sleeve 3, and the clamping portion 33 is clamped on the anti-loosening nut 5. A limiting hole 32 for the limiting member 4 to pass through is correspondingly provided on the guide sleeve 3, so that the guide sleeve 3 is limited, thereby keeping the relative position between the triggering portion 31 and the cantilever 22 unchanged. Wherein the clamping portion 33 can be a buckle, the nut can rotate relative to the guide sleeve 3, and the clamping portion 33 can also be other structures, which are not specifically limited.

[0064] Combined with Figures 5 to 14 , another embodiment provides a faucet, including a faucet body 6 and a quick disassembly and assembly structure for fixing the faucet body 6. The quick disassembly and assembly structure is the quick disassembly and assembly structure for the faucet described in any of the above embodiments. After the threaded tube 1 is fixed, the faucet body 6 is adaptively connected to the threaded tube 1, so that the faucet body 6 is fixed on the workbench surface.

[0065] Furthermore, the faucet body 6 has a fixing portion 61 and a spout portion 62, the fixing portion 61 and the spout portion 62 are connected by a connector 63, the threaded pipe 1 is inserted into the fixing portion 61, and is matched and connected with the connector 63, and the threaded pipe 1 is rotated by driving the connector 63. For example, the connector 63 is tubular, and a boss 631 is arranged along the circumference of the outer side surface, the boss 631 abuts on the fixing portion 61, and the part below the boss 631 is inserted into the fixing portion 61, and the connector 63 is axially limited by the locking nut 7. The connector 63 is provided with an internal thread adapted to the external thread of the threaded pipe 1, and the threaded pipe 1 is threadedly adapted to the connector 63, so that when the threaded pipe 1 rotates, no axial movement occurs. A wrench position is provided at the end above the boss 631, and the wrench position is clamped by a wrench or other tool to drive the connector 63 to rotate, and the threaded pipe 1 is correspondingly rotated, thereby adjusting the locking assembly 2.

[0066] In another embodiment, the fixing portion 61 is disposed on the fixing seat 8, the fixing seat 8 is used to abut against the work surface, and the limiter 4 is installed on the fixing seat 8. There are many ways to connect the fixing portion 61 and the fixing seat 8, which are not specifically limited.

[0067] Preferably, a connecting sleeve 9 is provided on the connecting member 63, and a tooth portion is provided along the axial direction of the connecting sleeve 9, and the faucet portion 62 is limited by the connecting sleeve 9 and the fixing portion 61. An opening is provided on the connecting sleeve 9, so that the connecting sleeve 9 has elasticity to be inserted into the connecting member 63, and the faucet portion 62 is limited and fixed by the connecting sleeve 9.

[0068] On the basis of the above-mentioned embodiment, in an optional embodiment of the present invention, the faucet is a pull-out faucet, and also includes a pull-out tube 10 connected to the faucet body 6. The pull-out tube 10 is passed through the threaded tube 1 and has a guiding function, so that the pulling process is smoother.

[0069] It should be mentioned that a valve core A1 is installed in the fixed part 61, and a handle A2 adapted to be connected to the valve core A1 is installed on its surface. The valve core A1 is connected to the adapter A3, and the adapter A3 is provided with a water inlet channel connected to the water pipe A4. During assembly, the adapter A3 is inserted into the valve cavity 611 from the inside of the fixed part 61, and the fastener A5 is locked with the adapter A3 from the other side of the valve cavity 611, so that the adapter A3 is limited in the valve cavity 611. This simplifies the internal structure of the faucet body 6 and can reduce the size of the faucet. Among them, how the valve core A1 controls the water output is a prior art and will not be repeated here.

[0070] The above are only preferred implementations of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
