Description

Technical Field

[0001] The present invention relates to the technical field of faucets, and specifically refers to a faucet that is convenient to install at places such as kitchen sinks. Background Art

[0002] Currently, sinks are installed in places that require water, such as in the kitchen. That is, a sink is installed on a fixed countertop, and a faucet is installed beside the sink. The faucet is generally fixed on the upper surface of the sink, etc., and the lower end of the faucet extends below the countertop (sink) and is connected to the tap water inlet joint or the outlet joint of the water purification facility. Usually, water inlet pipes and water purification facilities are installed below the sink, which means that the terrain is narrow at this position. When the lower end of the faucet is extended below the sink to be connected to the tap water joint or the joint of the water purification facility, it is very difficult to insert tools such as wrenches below the sink to tighten the connection between the faucet and the aforementioned joint, resulting in water seepage and leakage at the joint, bringing great inconvenience to users. Therefore, the existing installation method of faucets has deficiencies. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a faucet that is convenient to quickly install on a fixed countertop or sink, etc.

[0004] To achieve the above purpose, the technical solution is: a faucet that is convenient to quickly install, including a faucet body, a hollow water inlet shaft connected to the upper end thereof and communicating with its interior, and further including a union element movably sleeved on the water inlet shaft and located below the faucet body, and a lock assembly that is movably connected to the lower end of the union element and movably sleeved on the water inlet shaft and can move up and down; when the union element rotates, it can drive the lock assembly to move up or down along the axial direction of the water inlet shaft, so that the lock assembly locks or loosens on the countertop where the faucet is installed.

[0005] Further, the lock assembly includes a cylindrical body movably sleeved on the water inlet shaft, and an expansion cylinder body sleeved outside the cylindrical body and moving along the axial direction of the water inlet shaft together with it; an internal thread section is provided on the inner wall of the union element, and an external thread section corresponding to the internal thread section is provided at the upper end of the cylindrical body.

[0006] At least one longitudinal protrusion is provided on the outer wall of the water inlet shaft, and at least one longitudinal groove engaged with the longitudinal protrusion is provided on the inner wall of the cylindrical body.

[0007] Specifically, the expansion cylinder body includes a bottom ring body and an expansion cylinder integrally formed therewith; an inner guiding inclined surface is provided on the inner wall at the upper end of the expansion cylinder; a radial groove is provided inside the outer wall of the expansion cylinder, and a reset ring body is embedded in the radial groove.

[0008] The union element is integrally formed by an outer cylinder and an inner cylinder, and there is a gap between one section of the outer cylinder and the outer wall of the inner cylinder; an outer guiding inclined surface corresponding to the inner guiding inclined surface is provided on the outer wall of the lower section of the inner cylinder; the outer guiding inclined surface is located outside the inner guiding inclined surface.

[0009] The internal thread section is provided on the inner wall of the inner cylinder.

[0010] The expansion cylinder is formed by splicing a plurality of square vertical plates, and there is a longitudinal gap between adjacent two square vertical plates; the lower end of each square vertical plate is integrally formed with the bottom ring body.

[0011] A radial annular boss is provided on the outer wall of the lower end of the cylindrical body, and the bottom ring body is placed on the annular boss.

[0012] An annular limiting boss is provided on the outer wall of the upper section of the expansion cylinder in the radial direction.

[0013] A limiting nut is sleeved on the water inlet shaft, and the locking assembly is located above the limiting nut.

[0014] Technical effect: During installation, first connect the lower end of the hollow water inlet shaft to the external water pipe, and then extend the external water pipe and the lower end of the hollow water inlet shaft into the lower part of the water tank through the perforation at the position of the faucet installed on the water tank or the tabletop. The union element is located on the upper surface of the water tank or the tabletop and at the perforation, and the vertically movable locking assembly movably connected to the union element is located under the water tank. During installation, the union element is rotated clockwise or counterclockwise to drive the locking assembly to move upward along the axial direction of the water inlet shaft until the locking assembly is in close contact with the inner wall of the aforementioned perforation, so as to lock the whole formed by the union element, the locking assembly, the water inlet shaft and the faucet body on the water tank or the tabletop. When disassembly is needed, the union element is rotated in the reverse direction to drive the locking assembly to move downward, so that the locking assembly is loosened on the tabletop where the faucet is installed, and the disassembly can be completed.

Detailed implementation manners

[0021] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below with reference to the drawings and embodiments.

[0022] As Figure 2 shown, the embodiment of the present invention provides a faucet that is convenient for quick installation on a kitchen sink or countertop. During installation, there is no need to insert tools under the sink or countertop to tighten the connection position of the joint. It includes a faucet body 1, a hollow water inlet shaft 2 connected to the upper end thereof and communicating with its interior, and further includes a union element 3 movably sleeved on the water inlet shaft and located below the faucet body, and a locking assembly 4 movably connected to the lower end of the union element and movably sleeved on the water inlet shaft and capable of moving up and down along the water inlet shaft; with the above structure, during installation, the union element 3 is rotated clockwise or counterclockwise, driving the locking assembly 4 to move axially upward along the water inlet shaft until the locking assembly 4 is closely attached to the inner wall of the aforementioned through hole, thereby locking the whole formed by the union element 3, the locking assembly 4, the water inlet shaft 2 and the faucet body 1 on the sink or countertop. When disassembly is required, the union element 3 is rotated in the reverse direction, driving the locking assembly 4 to move downward, so that the locking assembly 4 is loosened on the countertop where the faucet is installed, and the disassembly of the faucet can be completed.

[0023] Specifically, as Figure 1-2As shown, in this embodiment, the locking assembly 4 includes a cylindrical body 401 movably sleeved on the water inlet shaft 2, and an expansion cylinder body 402 sleeved outside the cylindrical body and moving along the axial direction of the water inlet shaft together with it; an internal thread section 3a is provided on the inner wall of the union element 3, and an external thread section 401a corresponding to the internal thread section is provided at the upper end of the cylindrical body. At least one longitudinal protrusion 201 is provided on the outer wall of the water inlet shaft 2, and at least one longitudinal groove 401b engaged with the longitudinal protrusion is provided on the inner wall of the cylindrical body 401. With this structure, there is no special requirement for the number of longitudinal protrusions 201 on the outer wall of the water inlet shaft 2, and the same is true for the number of longitudinal grooves 401b, as long as the numbers of the two are the same. The purpose is that when the union element 3 rotates during use, the cylindrical body 401 is restricted to move only along the axial direction of the water inlet shaft and cannot rotate relative to the water inlet shaft 2, which is equivalent to a lead screw structure; therefore, even if one longitudinal groove 401b and one longitudinal protrusion 201 are provided respectively, this requirement can be met. However, for the sake of enhancing the structural stability, 3 - 4 can be provided. For example, in this embodiment, four longitudinal grooves 401b and four longitudinal protrusions 201 are provided, as Figure 5 shown.

[0024] As Figure 3-4 shown, specifically, the expansion cylinder body 402 includes a bottom ring body 402a and an expansion cylinder 402b integrally formed therewith. An internal guiding inclined surface 402c is provided on the inner wall at the upper end of the expansion cylinder; a radial groove 402d is provided inside the outer wall of the expansion cylinder, and a reset ring body 6 is embedded in the radial groove. The union element 3 is integrally formed by an outer cylinder body 301 and an inner cylinder body 302. There is a gap 303 between one section of the outer cylinder body and the outer wall of the inner cylinder body; an external guiding inclined surface 302a corresponding to the internal guiding inclined surface 402c is provided on the outer wall of the lower section of the inner cylinder body; the external guiding inclined surface is located outside the internal guiding inclined surface. The reset ring body here can be made of an elastic member made of a flexible material, such as a common rubber ring. As Figure 4As shown, when installing the faucet, the lower end of the water inlet shaft 2, the cylindrical body 401, and the expansion cylindrical body 402 all extend below the sink or countertop. The union element 3 is located on the upper surface of the sink or countertop and at the position of the perforation (not shown) provided on the sink or countertop for installing the faucet. Rotate the union element 3 (clockwise or counterclockwise), driving the cylindrical body 401 to move upward, and the expansion cylindrical body 402 follows upward. When the inner guiding inclined surface 402c contacts the outer guiding inclined surface 302a, when the expansion cylindrical body 402 continues to move upward, it will surely be expanded by the lower section of the inner cylindrical body 302. At this time, the upper end of the expansion cylindrical body 402 is inserted into the perforation of the sink or countertop. As the expansion amplitude of the expansion cylindrical body 402 increases (the reset ring body is simultaneously expanded and deformed) until it cannot be expanded anymore due to the limitation of the perforation, it means that the expansion cylindrical body 402 has been locked on the sink or countertop, and it also means that the whole formed by the union element 3, the locking assembly 4, the water inlet shaft 2, and the faucet body 1 is locked on the sink or countertop; and the purpose of setting the reset ring body 6 is that during disassembly, rotate the union element 3 in the reverse direction, the cylindrical body 401 moves downward, and the expansion cylindrical body 402 follows downward, then the expansion amplitude of it becomes smaller and smaller. During this process, the reset ring body resets and synchronously tightens the expansion cylindrical body so that the expansion cylindrical body can smoothly withdraw from the perforation. Therefore, without the tightening effect of the reset ring body, the expansion cylindrical body cannot return to its original state, and it may be difficult to remove it from the perforation, and thus difficult to disassemble the faucet.

[0025] Specifically, the internal thread section 3a is provided on the inner wall of the inner cylindrical body 302, as Figure 2 shown.

[0026] The expansion cylinder 402b is formed by splicing a plurality of square vertical plates 402b'; there is a longitudinal gap between adjacent two square vertical plates; the lower end of each square vertical plate is integrally formed with the bottom ring body 402a.

[0027] A radial annular boss 401c is provided on the outer wall of the lower end of the cylindrical body 401, and the bottom ring body 402a is placed on the annular boss.

[0028] An annular limit boss 402e is provided radially on the outer wall of the upper section of the expansion cylinder 402b; after installation is completed, the upper surface of the annular limit boss abuts against the inner bottom surface of the sink or countertop, that is, after the expansion cylinder 402b expands, the diameter of the annular limit boss is greater than the diameter of the perforation, preventing the whole faucet from being pulled out from the sink or countertop during use.

[0029] A limit nut 5 is sleeved on the water inlet shaft 2, and the locking assembly 4 is located above the limit nut. Its purpose is to prevent the locking assembly 4 from falling off the water inlet shaft 2 during the process of continuously rotating the union element 3 when disassembling the faucet if there is no block of the limit nut.

[0030] Compared with the similar faucets in the prior art, the faucet adopting the above structure does not need to insert tools under the sink or countertop to tighten the joint connection position between the faucet and other facilities, and is convenient for installation and disassembly.

[0031] In the above description, it should be noted that the corresponding terms such as "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, and can be the communication inside two components; "provided in" should be understood as "installed in, provided in", including fixed installation, movable installation and other installation methods.
