Description

Technical Field

[0001] The utility model relates to the technical field of faucets, and more specifically to a coaxially opened faucet. Background Art

[0002] At present, most faucet styles and handle switches adopt a flip-opening method or a method where the handle and the water spout are not coaxial. Fig.10 The faucet structure shown is flip-open, and the handle has the risk of interfering with the semicircular cover when flip-open. Fig.11 The faucet structure shown in the figure has a handle and a water spout that are not coaxial. When the faucet is flipped open, there is also a risk of interference with the semicircular cover. The reason for this is that the handle and the semicircular cover have cumulative tolerances in the prior art, or the tolerance size of the valve core is too large after long-term use, so the handle is easy to interfere with the semicircular cover, resulting in failure to open.

[0003] The Chinese patent with publication number CN214946585U previously applied by the applicant discloses a single-handle dual-control faucet, which realizes dual control by controlling the opening of the faucet and the adjustment of the water temperature through the horizontal rotation adapter of the handle. However, the patent lacks an effective structural design to limit the rotation of the handle, has poor torsion resistance, and has a high risk of being damaged. Utility Model Content

[0004] The utility model aims to provide a coaxially opened faucet, which adopts a structural design of a handle rotating to open the faucet, so as to solve the technical problems that the handle of a traditional faucet that is opened by somersault or the handle is not opened coaxially is easy to interfere with the semicircular cover, resulting in a high risk of opening failure, and a limiting structure is designed to improve the torsion resistance of the handle and reduce the risk of damage.

[0005] In order to achieve these purposes and other advantages according to the utility model, a coaxially opened faucet is provided, comprising: a water outlet, a valve core connected to the water outlet, and a water inlet pipe connected to the valve core;

[0006] A turntable is arranged above the valve core and connected to the valve core, and the turntable rotates to drive the valve core to open and close;

[0007] A connecting piece is provided at the lower part of the handle, and the handle is connected to the lower turntable through the connecting piece. When the handle rotates, the turntable is driven to rotate through the connecting piece;

[0008] A fixed disk is arranged between the handle and the rotating disk, and the fixed disk has a limiting portion to limit the activity space of the connecting member, thereby limiting the rotation angle of the handle.

[0009] The rotation of the handle in the above scheme drives the turntable to rotate through the connecting part, and the turntable drives the valve core to open and close. The fixed disk limits the activity space of the connecting part, thereby limiting the rotation space of the handle. The limiting structure composed of the connecting part and the fixed disk limiting part effectively avoids damage due to excessive twisting, thereby improving the torsion resistance and reducing the risk of damage.

[0010] Preferably, the valve core, the rotating disk, the fixed disk, and the handle are coaxially arranged, from top to bottom, in the order of: handle, fixed disk, rotating disk, valve core. This is significantly different from the traditional faucet structure design that opens by flipping or the handle opens out of the same axis, and solves the technical problem that the handle easily interferes with the semicircular cover and the risk of failure in opening is high.

[0011] Preferably, the handle is arranged in a horizontally rotating structure, which is significantly different from the traditional faucet structure design that opens by flipping or the handle opens out of the same axis, and solves the technical problem that the handle easily interferes with the semicircular cover and the risk of opening failure is high.

[0013] Preferably, when the handle is rotated to below the water spout, the valve core is closed, and when the handle is rotated out from below the water spout, the valve core is opened. This design allows the handle to be retracted below the water spout when the faucet is working, thereby reducing the occupation of the hole, being beautiful, and preventing accidental touching or breaking.

[0014] Preferably, the handle is a flat structure, and when it is retracted below the water spout, it does not protrude and is more aesthetically pleasing.

[0015] Preferably, the water spout is also a flat structure, and the handle with a flat structure is more compatible.

[0016] Preferably, the water outlet is provided with a water inlet and a water outlet, and the water inlet is provided as a protruding connection port;

[0017] The handle is provided with a mounting through hole and an inlay hole, and wear-resistant rings are provided on the upper and lower sides of the mounting through hole; a connecting piece is provided at the bottom of the handle;

[0018] The fixing plate is provided with a central through hole, and the limiting parts are limiting holes, which are provided on both sides of the central through hole;

[0019] A nut is provided, and the connection port of the water inlet is meshed with the nut after passing through the handle installation through hole and the central through hole of the fixing plate.

[0020] Such a structural design is convenient for assembly and manufacturing.

[0021] Preferably, a spline hole is provided in the center of the turntable, the spline hole cooperates with the spline on the top of the valve core, a threaded hole is provided on the turntable, and the connecting piece of the handle passes through the limiting hole of the fixed plate and is connected and fixed with the threaded hole. This design is convenient for assembly and disassembly, and the connecting piece moves in the space of the limiting hole to play a limiting role.

[0022] Preferably, the connecting piece of the handle is a column with a screw hole at the bottom, and a screw is arranged to pass through the threaded hole of the turntable and engage with the screw hole of the column, so that the connecting piece is fixed to the turntable. This design is convenient for assembly.

[0023] Preferably, it also includes a shell, a positioning hole is arranged inside the shell, the valve core is installed in the positioning hole, and a valve core pressure cover is arranged to press the valve core in the positioning hole.

[0024] Preferably, a hexagon socket screw is also provided, which penetrates the outer wall of the housing and abuts against the internal fixing plate, so that the housing, the fixing plate and the water outlet are fixed as a whole. This structural design facilitates installation and fixation, and also makes the overall structure of the faucet more stable.

[0025] Preferably, the inlay hole of the handle is installed with an inlay, and the inlay is used for decoration.

[0026] The utility model at least has the following beneficial effects:

[0027] 1. The handle limit structure is designed to effectively improve the handle's anti-torsion ability.

[0028] 2. The structure of the semicircular cover of the traditional faucet is eliminated, and the handle drives the valve core to open and close by coaxial horizontal rotation. Therefore, there is no interference between the handle and the semicircular cover, which reduces the risk of handle opening failure and saves a semicircular cover part.

[0029] 3. The handle has a flat structure design and is retracted under the water spout when not in use, which does not take up space, is more beautiful, and is difficult to be damaged by accidental collisions.

[0030] 4. Simple structure, easy assembly and disassembly, and cost saving.

[0047] Fig.10 The present invention is a schematic diagram of the planed surface structure of an existing faucet that is opened by flipping.

[0048] Fig.11 The present invention is a schematic diagram of the planed structure of an existing faucet that uses handles that are opened in different axes.

[0049] Fig.10 and Fig.11 The faucet structure is mainly composed of a traditional faucet handle 41, a semicircular cover 42, and a valve core 43. When the faucet handle is flipped open, there is a cumulative tolerance between the handle and the semicircular cover, or the tolerance size of the valve core will be too large after long-term use, and the handle is easy to interfere with the semicircular cover, resulting in failure to open.

[0050] like Figures 1 to 9 As shown, a coaxially opened faucet includes: a water outlet 2, a valve core 13 connected to the water outlet 2, and a water inlet pipe 16 connected to the valve core 13; the water pipe 16 is connected to the valve core water inlet 132 at the lower part of the valve core, and the water in the water inlet pipe 16 enters the water outlet 2 through the valve core 13 and then is output. The water outlet and water shut-off can be achieved by controlling the opening and closing of the valve core 13.

[0051] In order to control the valve core 13, a rotary disk 10 is provided to be connected to the valve core 13, and the rotary disk 10 rotates to drive the valve core 13 to open and close;

[0052] In order to control the turntable 10, a rotatable handle 5 is provided, which is connected to the turntable 10 through a connecting member 501. When the handle 5 rotates, the turntable 10 is driven to rotate through the connecting member 501;

[0053] In order to limit the rotation angle of the handle 5, a fixed plate 7 is provided. The fixed plate 7 has a limiting portion 701 to limit the activity space of the connecting member 501, thereby limiting the rotation angle of the handle 5, preventing the handle from being twisted due to excessive rotation, and improving the torsion resistance.

[0054] Preferably, the handle 5, the fixed disk 7, the rotating disk 10, and the valve core 13 are arranged in sequence from top to bottom.

[0055] Preferably, the limiting portion 701 can be a limiting hole or a limiting groove or a limiting rod, etc. The size of the limiting portion 701 can be set as required to limit the handle to rotate within the designed range. The connecting member 501 can be a connecting column, a connecting piece, a connecting rod, etc., which can drive the turntable to rotate.

[0056] When the faucet of this embodiment is turned on or off, the operating handle 5 rotates, the connecting member 501 drives the rotating disk 10 to rotate, and the rotating disk 10 drives the valve core 13 to open and close. The limiting portion 701 of the fixed disk 7 limits the activity space of the connecting member 501. When the handle rotates excessively, the connecting member is blocked by the limiting portion, thereby limiting the rotation angle or space of the handle. The limiting structure composed of the connecting member and the limiting portion of the fixed disk effectively prevents the handle from being damaged due to excessive twisting, thereby improving the torsion resistance and reducing the risk of damage.

[0057] Further, in another embodiment, Figure 1 to Figure 4 As shown, the valve core 13, the rotating disk 10, the fixed disk 7, and the handle 5 are coaxially arranged to form a structure for coaxial opening of the faucet. During opening and closing, the handle 5 can be rotated horizontally without flipping. In the legend, preferably, the handle 5, the fixed disk 7, the rotating disk 10, and the valve core 13 are arranged in sequence from top to bottom. This design is significantly different from the traditional faucet structure design of flip-opening and non-coaxial opening of the handle, and solves the technical problem that the handle is easy to interfere with the semicircular cover and the risk of opening failure is high.

[0058] Preferably, the handle 5 is arranged in a horizontally rotating structure, which is significantly different from the traditional faucet structure design that is opened by somersault and the handle is opened out of coaxiality, and solves the technical problem that the handle is easy to interfere with the semicircular cover and the risk of opening failure is high.

[0059] Further, in another embodiment, Figure 1 to Figure 4 As shown, under the restriction of the limiting portion 701 , the handle 5 can be horizontally rotated to the position directly below the water spout 2 to reduce the occupied space, and can also be rotated out from the position directly below the water spout 2 .

[0060] Preferably, when the handle 5 is rotated to below the water spout 2, the valve core 13 is closed, and when the handle 5 is rotated out from below the water spout 2, the valve core 13 is opened. This design allows the handle to be retracted below the water spout when the faucet is working, thereby reducing the occupation of the hole, being beautiful, and preventing accidental touch or breakage.

[0061] Further, in another embodiment, Figure 1 to Figure 4 and Figure 6As shown, the handle 5 is a flat structure. When it converges to the bottom of the water spout 2 and overlaps the water spout 2, the handle is converged and does not protrude from the water spout, occupies less space, and is more beautiful. As an alternative, the handle can also be set to other shapes.

[0062] Further, in another embodiment, Figure 1 to Figure 4 and Figure 5 As shown, the water spout 2 is also a flat structure, which is more compatible with the flat handle 5. As an alternative, the water spout can also be designed in other shapes.

[0063] Further, in another embodiment, Figure 2 As shown, the water outlet 2 is provided with a water inlet 201 and a water outlet 202. Figure 3 As shown, the internal channel of the water outlet 2 connects the water inlet 201 and the water outlet 202, and the water inlet 201 is configured as a protruding connection port 203; preferably, the connection port 203 is provided with an external thread and an external flat portion 204; preferably, the water outlet 202 is provided with a bubbler 1;

[0064] like Figure 6 As shown, the handle 5 is provided with a mounting through hole 502 and an inlay hole 503, and wear-resistant rings are matched on the upper and lower sides of the mounting through hole 502; the connecting piece 501 is arranged at the bottom of the handle 5; preferably, the wear-resistant ring includes a small wear-resistant ring 3 and a large wear-resistant ring 6, the small wear-resistant ring 3 is matched on the upper side of the mounting through hole 502, and the large wear-resistant ring is matched on the lower side of the mounting through hole 502;

[0065] like Figure 7 As shown, the fixed disk 7 is provided with a central through hole 702, and the limiting portion 701 is a limiting hole, and the limiting holes 701 are provided on both sides of the central through hole 702; preferably, the size of the limiting hole is set as needed, the purpose is to provide a set amount of activity for the connecting member, thereby limiting the rotation angle of the handle, such as the handle can be rotated into the lower part of the water spout, and rotated out from the lower part of the water spout. In one embodiment, the limiting hole is a fan ring structure, and the central angle of the fan ring structure is 45 to 180°; preferably, the central through hole 702 is provided with an inner flat position, when the fixed disk is assembled with the water spout, the inner flat position of the central through hole 702 cooperates with the outer flat position 204 of the connecting port 203 to prevent the fixed disk 7 from rotating; when the fixed disk 7 is assembled with the handle 5, the connecting member 501 passes downward through the limiting portion 701;

[0066] like Figure 1 and Figure 3 As shown, a nut 9 is provided. During assembly, after the connection port 203 of the water inlet passes through the mounting through hole of the handle 5 and the central through hole of the fixing plate 7, the external thread of the connection port 203 engages with the nut, thereby fixing the fixing plate 7 and the water outlet. The mounting through hole of the handle is larger than the connection port 203 and is circular, so it can be rotated, but the rotation angle is limited by the limit portion.

[0067] In this embodiment, such a structural design is convenient for assembly and manufacturing, eliminates the design of the traditional semicircular cover, and reduces the cost.

[0068] Further, in another embodiment, Figure 8 and 9 As shown, a spline hole 101 is provided at the center of the rotating disk 10, and the spline hole 101 cooperates with the spline 130 at the top of the valve core 13, and a threaded hole 102 is provided on the rotating disk 10, and the connecting piece 501 of the handle 5 passes through the limiting hole of the fixing disk 7 and is connected and fixed to the threaded hole 102. This design is convenient for assembly and disassembly, and the connecting piece moves in the space of the limiting hole, and plays a limiting role.

[0069] Preferably, Figure 1 , 3 and Figure 6 As shown, the connecting piece 501 of the handle 5 is a column with a screw hole at the bottom, and a screw 11 is arranged to pass through the threaded hole 102 of the turntable 10 and engage with the screw hole of the column, so that the connecting piece 501 is fixed to the turntable 10. This design facilitates assembly and improves production efficiency.

[0070] Further, in another embodiment, Figure 1 to Figure 4 As shown, it also includes a housing 14, a positioning hole is arranged inside the housing 14, the valve core 13 is installed in the positioning hole, and a valve core gland 12 is arranged to press the valve core 13 in the positioning hole.

[0071] Further, in another embodiment, Figure 1 to Figure 4 As shown, a hexagon socket screw 15 is also provided. After assembly, as shown in FIG. Figure 3 As shown, the hexagon socket screw 15 penetrates the outer wall of the housing 14 and abuts against the internal fixing plate 7, so that the housing 14, the fixing plate 7, and the water spout 2 are fixed as a whole. This structural design is convenient for installation and fixation, and also makes the overall structure of the faucet more stable.

[0072] Further, in another embodiment, Figure 1 and 6 As shown, the inlay hole 503 of the handle 5 is installed with an inlay 4, which is used for decoration and can be set as a desired display ornament as needed to improve the quality. Preferably, the inlay is a stone inlay, a metal inlay or a plastic inlay.
