Description

Technical Field

[0001] The utility model relates to the technical field of faucet installation, in particular to an installation structure of a pressing valve core control component. Background Art

[0002] With the improvement of people's living standards, wash basins have gradually changed from traditional wash basins to modern new sanitary ware basins. Currently, single-hole basins, double-hole basins, and three-hole basins are common on the market. The wash basin can be equipped with a faucet with a four-hole or eight-hole. Usually, the standard aperture of the installation hole of the faucet of a three-hole wash basin is φ35mm. Based on the existing push-on valve core structure, its outer diameter is usually ≥φ30mm, and the outer diameter of the valve body is φ37mm, which is larger than the aperture of the existing faucet installation hole and cannot meet the installation requirements. In this case, the countertop needs to be reworked so that the size of the countertop opening can meet the outer diameter of the valve core and the valve body after connection. Sometimes, it may not be installed, which has great limitations on the product.

[0003] To address this problem, technicians designed an extended sleeve that is connected to the valve body. The valve core and valve body are installed at the bottom of the extended sleeve, and the cylinder of the extended sleeve is passed through the installation hole of the countertop to achieve the assembly of the valve core and valve body with the basin / countertop. However, due to the use of the extended sleeve, it is difficult for the handwheel that controls the valve core to accurately control the valve core. Especially for the push valve, the push piece is easily stuck during the stroke when pressing down to start the push valve, which makes the user feel poor. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0035] The following is combined with Figures 1 to 5 The technical solution of the utility model is further illustrated by specific implementation methods.

[0036] In order to solve the problem that valve bodies 2 with different outer diameters are difficult to match and install on the installation panel 0 with a standard opening, an improved technical solution of an extended sleeve 3 is designed. The valve body 2 (the pressing valve core 1 is arranged in the valve body 2) is connected with the installation ring 32 of the extended sleeve 3. The installation ring 32 and the valve body 2 are located at the bottom of the installation panel 0, and the cylinder 31 part of the extended sleeve 3 passes through the installation hole 01 from the bottom to the top from the bottom of the installation panel 0. The extended sleeve 3 is fixed to the installation panel 0 through the fixing seat 33 and the part of the cylinder 31 protruding from the upper surface of the installation panel 0. The cylinder 31 can be made into different lengths according to the thickness of different installation panels 0 to meet the installation requirements of different installation scenarios. However, due to the introduction of the extended sleeve 3, when the pressing plate 421 is pressed down to start the pressing valve core, the vertical stroke required to press the pressing plate 421 increases, which causes the pressing plate 421 to be easily stuck in the extended sleeve 3 due to loss of balance during the pressing process, which puts the user in a dilemma. Therefore, the present application provides an installation structure of a press valve core control assembly, comprising a press valve core 1, a valve body 2, an extended sleeve 3 and a control assembly 4;

[0037] The extended sleeve 3 includes a cylinder 31 and a mounting ring 32, wherein the cylinder 31 is located above the mounting ring 32, the cylinder 31 is used to pass through the mounting hole 01 provided in the mounting panel 0, the mounting ring 32 is used to be clamped against the bottom of the mounting panel 0, the mounting ring 32 is used to be installed and connected with the valve body 2, the top of the cylinder 31 protrudes from the upper surface of the mounting panel 0, and the top of the cylinder 31 is installed and connected with the fixing seat 33; the valve body 2 is connected to the interior of the extended sleeve 3, and the pressing valve core 1 is provided in the internal communication space between the valve body 2 and the extended sleeve 3;

[0038] The control assembly 4 includes a control seat 41, a pressing plate 421 and an extension column 422. The control seat 41 covers the fixed seat 31. The control seat 41 is provided with a accommodating chamber 411 with an open top. A vertical guide portion is provided in the accommodating chamber 411. The pressing plate 421 is located in the accommodating chamber 411. The pressing plate 421 moves up and down relative to the accommodating chamber 411 under the action of the vertical guide portion. The extension column 422 is provided at the bottom of the pressing plate 421. One end of the extension column 422 away from the pressing plate 421 passes through the control seat 41 and extends downward inside the cylinder 31. One end of the extension column 422 away from the pressing plate 421 is installed and connected to the pressing valve core 1. By pressing the pressing plate 421, the extension column 422 is driven to press and drive the pressing valve core 1 to open.

[0039] The control assembly 4 is arranged on the top surface of the installation panel 0, and is used for the user to control the opening and closing of the push valve to control the use of the faucet. Since the extended sleeve 3 is used to adapt to the installation of the valve body with a larger outer diameter and the installation panel 0 with different thicknesses, a pressing member 42 having a pressing plate 421 and an extension column 422 is provided, and the extension column 422 extends downward in the cylinder 31 to connect with the push valve core 1. When the user presses the pressing plate 421 downward, the pressing plate 421 moves downward under the guidance of the vertical guide part of the accommodating cavity 411, and transmits the pressing force to the push valve core 1 through the extension column 422, thereby opening the push valve. Since the pressing plate 421 of the pressing member is arranged in the accommodating cavity 411, and the extension column 422 passes through the bottom of the control seat 41 and is located inside the cylinder 31, and the extension column 422 is always connected to the pressing valve core 1 inside the cylinder 31, the vertical stroke of the pressing plate 421 is always the vertical height of the accommodating cavity 411 of the control seat, the pressing plate 421 is not easy to get stuck, and the extension column 422 can be designed with different lengths according to actual needs to meet the installation panels 0 of different thicknesses.

[0040] The utility model provides a control seat 41 in the control component 4 for accommodating and guiding the pressing plate 421, and provides an extension column 422 to cooperate with the extension sleeves 3 of different lengths, and the extension column 422 is installed and connected to the pressing valve core 1, so as to solve the problem that the pressing plate 421 is prone to lose balance in the horizontal direction and get stuck in the extension sleeve 3 and is difficult to recover when moving up and down in the extension sleeve 3, due to the increase in the length of the extension sleeve 3. This design makes the control component control the pressing valve core 1 more accurately and sensitively, and is suitable for valve body accessories with different outer diameters and mounting platforms (panels) of different thicknesses.

[0041] Furthermore, a vertical through slot 4221 is provided inside the extension column 422, the top opening of the through slot 4221 passes through the pressing plate 421, an annular boss 4222 is provided on the inner wall of the lower end of the through slot 4221, and a thread is provided on the side wall of the annular boss 4222, and the thread matches with the fastener to achieve locking;

[0042] The pressing portion 11 of the pressing valve core 1 is provided with the thread matched with the fastener.

[0043] By providing a through groove 4221 inside the extension column 422, and providing a threaded annular boss 4222 on the inner wall of the lower end of the through groove 4221, a fastener such as a screw is screwed from the upper opening of the through groove 4221 into the threads of the annular boss 4222 and the valve core pressing part 11 from top to bottom, thereby locking the pressing member 42 and the pressing valve core 1. In addition, the annular boss 4222 can limit the nut part of the screw, which plays a role in prompting the pressing member 42 and the pressing valve core 1 to be assembled.

[0044] Using fasteners to tightly connect the pressing member 42 and the pressing valve core 1 can ensure that the movement of the pressing member 42 is accurately transmitted to the pressing valve core 1, avoiding operational errors caused by loose connections or gaps, and improving the accuracy and reliability of the product.

[0045] Furthermore, an inner tube 412 is extended downward from the bottom of the control seat 41, the interior of the inner tube 412 is communicated with the accommodating cavity 411, the inner tube 412 is rotatably located inside the cylinder 31, and the extension column 422 is located inside the inner tube 412;

[0046] The bottom of the inner tube 412 is installed and connected to the rotating adjustment sleeve 12 of the pressing valve core 1 .

[0047] As mentioned in the Chinese patent CN109654277B, the valve core also realizes the function of adjusting the water flow rate of the valve core by setting an adjustment sleeve. The control seat 41 of the control assembly of an embodiment of the utility model is also provided with an inner tube 412 at the bottom, the inner tube 412 is extended in the cylinder 31, and the bottom of the inner tube 412 is installed and connected with the rotating adjustment sleeve 12 of the valve core. By rotating the control seat 41 located on the top surface of the installation panel 0, the rotating adjustment sleeve 12 of the pressing valve core 1 can be driven by the inner tube 412 to control the rotation of the pressing valve core 1, so as to adjust the water flow rate of the pressing valve core 1.

[0048] To further explain, since the extension column 422 is located inside the inner tube 412, the rotation of the control seat 41 and the inner tube 412 has no effect on the pressing piece 42. The control seat 41 controls the water flow rate of the pressing valve core 1, and the pressing piece 42 controls the start and stop of the water flow of the pressing valve core 1. They are independent of each other but have a compact structure.

[0049] Furthermore, the bottom of the inner tube 412 is recessed inward to form a limiting step 4121, and a limiting ring 413 is provided in the inner tube 412. The limiting ring 413 is sleeved on the pressing valve core 1, and the limiting ring 413 is located above the limiting step 4121;

[0050] The inner wall of the limiting step 4121 is provided with internal spline teeth 4122 , and the internal spline teeth 4122 cooperate with the external spline teeth of the rotation adjustment sleeve 12 .

[0051] The limiting ring 413 is arranged inside the inner tube 412 and sleeved on the push valve core 1. The limiting ring 413 is located above the limiting step 4121 and there is a certain space between the limiting ring 413 and the limiting step 4121. When the pressing member 42 is pressed to drive the push valve core 1 to move downward, the limiting ring 413 sleeved on the valve core moves downward with the push valve core 1. When the limiting ring 413 moves to abut against the limiting step 4121, it serves as a reminder that the pressure is in place and protects the push valve core 1 to prevent the user from causing irreversible damage to the push valve core 1 when pressing with greater force and displacement.

[0052] Furthermore, the inner wall of the limiting step 4121 is provided with internal spline teeth 4122, which match the external spline teeth of the rotation adjustment sleeve 12. The design of the spline teeth increases the precision of the rotation adjustment, making the rotation adjustment of the pressing valve core 1 more accurate and reliable. At the same time, the cooperation between the spline teeth can also effectively prevent loosening or slipping during the rotation adjustment process, thereby improving the reliability of the adjustment.

[0053] Furthermore, the control assembly 4 further includes a pressing panel 43 , which is covered on the top of the pressing plate 421 , and the top surface of the pressing panel 43 is higher than the top of the control seat 41 .

[0054] By setting a pressing panel 43 on the top of the pressing plate 421 and making the top surface of the pressing panel 43 higher than the top of the control seat 41, such a design enables the user to find the pressing point more intuitively during operation, thereby improving the convenience and accuracy of the operation.

[0055] Furthermore, a guide tube 423 is extended upward from the top of the pressing plate 421, and an annular cover plate 431 is extended downward from the bottom of the pressing panel 43, and the cover plate 431 covers the guide tube 423;

[0056] The guide tube 423 is provided with a vertical guide groove 4231 , and the inner wall of the cover plate 431 is provided with a vertical rib 432 , and the rib 432 matches the guide groove 4231 .

[0057] By setting the guide tube 423 on the pressing plate 421 and setting a matching annular cover plate 431 at the bottom of the pressing panel 43, the pressing panel 43 is entirely covered with the wrapped guide tube 423. Furthermore, the guide groove 4231 on the guide tube 423 matches the convex rib 432 on the inner wall of the cover plate 431, so that the assembly of the pressing panel 43 and the pressing member 42 is more accurate and quick. When the assembly is completed, the convex rib 432 is stuck in the vertically arranged guide groove 4231, avoiding the rotation of the pressing panel 43. In addition, when the pressing valve core 1 is opened by pressing the pressing panel 43, the convex rib of the pressing panel 43 is always kept in the guide groove 4231 during the vertical movement, and the up and down movement is more accurate.

[0058] Furthermore, the inner wall of the mounting ring 32 is provided with a first thread 321, and the first thread 321 is connected to the thread on the top of the valve body 2;

[0059] The outer wall of the top of the cylinder 31 is provided with a second thread 311, and the second thread 311 is threadedly connected to the fixing seat 33;

[0060] The mounting ring 32 is provided with a plurality of threaded holes, and screws 34 are provided in the threaded holes. The screws 34 are screwed into the threaded holes from bottom to top.

[0061] The inner wall of the mounting ring 32 is provided with a first thread 321, and the mounting ring 32 is connected to the top of the valve body 2 by threading; the outer wall of the top of the cylinder 31 is provided with a second thread 311, and the fixing seat 33 is connected to the top of the cylinder 31 by threading; the mounting ring 32 is provided with a plurality of threaded holes, and after the extended sleeve 3 passes through the mounting hole 01, the mounting ring 32 is clamped against the bottom of the mounting panel 0, and the screw 34 is screwed into the threaded hole from bottom to top until the top of the screw 32 is against the bottom of the mounting panel 0, so as to realize the locking of the bottom of the extended sleeve 3 and the mounting panel 0. The above design ensures the tight connection between the mounting ring 32 and the valve body 2, the cylinder 31 and the fixing seat 33, and the extended sleeve 3 and the mounting panel 0, and improves the stability and reliability of the installation.

[0062] Furthermore, a rigid sheet 51 and a buffer gasket 52 are provided between the mounting ring 32 and the mounting panel 0 , and the rigid sheet 51 abuts against the top of the screw 34 .

[0063] A rigid sheet 51 and a buffer gasket 52 are provided between the mounting ring 32 and the mounting panel 0. The rigid sheet 51 abuts against the top of the screw 34. It is worth noting that since the screw 34 is screwed into the threaded hole of the mounting ring 32 from bottom to top, the top of the screw 34 referred to here is the end of the screw rod, and the bottom of the screw 34 is the end of the nut. When the screw 34 passes through the screw hole on the mounting ring 32 to fix the bottom of the extension sleeve 3 to the bottom surface of the mounting panel 0, the bottom of the mounting panel 0 abuts against the top of the screw 34, which will cause certain wear on the mounting panel 0. Therefore, after the rigid sheet 51 is provided between the screw 34 and the mounting panel 0, there is no direct contact between the screw 34 and the mounting panel 0, which plays a protective role on the mounting panel 0. On the other hand, the provision of the rigid sheet 51 increases the force-bearing area between the screw 34 and the mounting panel 0, making the connection between the screw 34 and the mounting panel 0 more stable.

[0064] Furthermore, the buffer gasket 52 arranged between the mounting panel 0 and the rigid sheet 51 has a buffering effect. When the screw is screwed into the screw hole on the mounting ring 32 and abuts against the rigid sheet 51, a certain pressure and friction will be generated between the rigid sheet 51 and the mounting panel 0, causing a certain amount of wear on the mounting panel 0. The setting of the buffer gasket 52 buffers part of the pressure and friction, and plays a certain protective role for the mounting panel 0.

[0065] Furthermore, a wear-resistant ring 53 is provided between the fixing seat 33 and the bottom of the control seat 41 .

[0066] A wear-resistant ring 53 is provided between the fixing seat 33 and the bottom of the control seat 41. The wear-resistant ring 53 mainly plays the role of buffering and sealing. The fixing seat 33 and the control seat 41 are not in direct contact with each other, which reduces the friction between the fixing seat 33 and the control seat 41, reduces the wear on the fixing seat 33, and prolongs the service life of the fixing seat 33 to a certain extent. The wear-resistant ring 53 is made of wear-resistant material, such as polytetrafluoroethylene (PTFE), etc., which can effectively reduce such wear and prolong the service life of the control component.

[0067] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
