[0037] The utility model provides a drainage speed regulating structure of a drainage valve, which is used to adjust the water flow rate of the drainage valve to adjust the drainage speed. Figure 3 , including a drain valve base 1 and a flow rate regulating component 2; the drain valve base 1 is used to be installed in a drain valve (not shown in the figure), the drain valve base 1 forms a drainage channel 3, and the flow rate regulating component 2 is arranged in the drainage channel 3; the flow rate regulating component 2 includes a plurality of baffles 4, and the plurality of baffles 4 rotate relatively around the same axis, and the side of each baffle 4 is located on the axis, and the axis is parallel to the radial cross-section of the drainage channel 3; the areas of the plurality of baffles 4 are different; by rotating one baffle 4, or rotating a plurality of baffles 4, the water flow in the drainage channel 3 is reduced, so as to achieve the purpose of regulating the drainage speed.
[0038] In this specific embodiment, the focus is on Figure 1 , the number of baffles 4 is two, namely the first baffle 5 and the second baffle 6. Of course, in other embodiments, the number of baffles 4 can also be three, four, etc., and no specific limitation is made here. It only needs to be able to rotate to adjust the discharge speed, and those skilled in the art can adjust it according to the specific situation.
[0039] In this specific embodiment, the first baffle 5 and the second baffle 6 are both fan-shaped structures. Of course, in other embodiments, the first baffle 5 and the second baffle 6 can also be parts of an ellipse or other shapes without specific limitation.
[0040] In this specific embodiment, the first baffle 5 is pivoted on the drain valve base 1, and can be positioned when rotated to be parallel to the radial cross section of the drain channel 3, or when rotated to be perpendicular to the radial cross section of the drain channel 3; the second baffle 6 is pivoted on the first baffle 5, and can be positioned when rotated to be parallel to the radial cross section of the drain channel 3, or when rotated to be perpendicular to the radial cross section of the drain channel 3. Of course, in other embodiments, multiple gears can be adjusted to achieve the positioning of the first baffle 5 and the second baffle 6 at different angles, without specific limitation.
[0041] In this specific embodiment, the focus is on Figure 2 and Figure 4A first rotating shaft 7 is formed on the first baffle 5, and a first pin shaft 71 is formed at the outer end of the first rotating shaft 7. A first mounting hole 11 is formed on the side wall of the drain valve base 1. The first pin shaft 71 is inserted into and rotatably engaged in the first mounting hole 11, so that the first baffle 5 rotates relative to the drainage channel 3; a yield area 72 is formed in the middle of the first rotating shaft 7, and a second pin shaft 73 is formed in the yield area 72 at the inner end of the first rotating shaft 7. A second rotating shaft 8 is formed on the second baffle 6, and a second mounting hole 81 is formed at the outer end of the second rotating shaft 8. The second pin shaft 73 is inserted into and rotatably engaged in the second mounting hole 81, so that the second baffle 6 rotates relative to the first baffle 5.
[0042] In this specific embodiment, the focus is on Figure 2 and Figure 4 A first groove 111 is formed on the side wall of the first mounting hole 11, and a first protrusion 711 is formed on the outer side of the first pin shaft 71, so that the first protrusion 711 is inserted into the first groove 111 to position the first baffle 5. When in use, the first baffle 5 is driven to rotate around the axis, and the first rotating shaft 7 drives the first protrusion 711 on the first pin shaft 71 to rotate relative to the first mounting hole 11. When the first protrusion 711 rotates to align with the first groove 111, it is inserted into the first groove 111;
[0043] A second groove 811 is formed on the side wall of the second mounting hole 81, and a second protrusion 731 is formed on the outer side surface of the second pin shaft 73, so that the second protrusion 731 is inserted into the second groove 811 to position the second baffle 6. When in use, the second baffle 6 is driven to rotate around the axis to rotate the second rotating shaft 8 relative to the second pin shaft 73. When the second groove 811 on the second rotating shaft 8 is rotated to align with the second protrusion 731, the second protrusion 731 is inserted into the second groove 811.
[0044] In this specific embodiment, the number of the first grooves 111 is at least two, so that when the first protrusion 711 is inserted into the first groove 111, the first baffle 5 is positioned parallel to the radial cross section of the drainage channel 3, or positioned perpendicular to the radial cross section of the drainage channel 3, to achieve two-gear adjustment; the number of the second grooves 811 is at least two, so that when the second protrusion 731 is inserted into the second groove 811, the second baffle 6 is positioned parallel to the radial cross section of the drainage channel 3, or positioned perpendicular to the radial cross section of the drainage channel 3, to achieve two-gear adjustment. Specifically, the first groove 111 and the second groove 811 correspond in position, both are parallel to the radial cross section of the drainage channel 3, or both are perpendicular to the radial cross section of the drainage channel 3, and accordingly, the first protrusion 711 and the second protrusion 731 correspond in position, so that the first baffle 5 and the second baffle 6 can be positioned perpendicular to the radial cross section of the drainage channel 3, or parallel to the radial cross section of the drainage channel 3.
[0045] When in use, the first baffle 5 and the second baffle 6 are simultaneously rotated to be perpendicular to the radial cross section of the drainage channel 3, and the water flow rate is maximum (such as Figure 5or when the discharge speed reaches the maximum, only the first baffle 5 is rotated to be parallel to the radial section of the drainage channel 3 (as shown in Figure 7 As shown), the water flow rate is reduced; or when the drainage speed reaches the maximum, only the second baffle 6 is rotated to be parallel to the radial section of the drainage channel 3 to reduce the water flow rate. Due to the different areas of the first baffle 5 and the second baffle 6, different drainage speeds are achieved; or when both the first baffle 5 and the second baffle 6 are rotated to be parallel to the radial section of the drainage channel 3, the water flow rate is minimized (as shown). Figure 8 As shown), the discharge speed reaches the minimum, and the water flow rate can be adjusted in multiple gears.
[0046] In order to enable the first baffle 5 and the second baffle 6 to be positioned more stably, preferably, the number of first protrusions 711 is two, and they are symmetrically arranged on the two opposite outer sides of the first pin shaft 71. Correspondingly, the number of first grooves 111 is four, which are arranged corresponding to the first protrusions 711, and can allow two first protrusions 711 to be simultaneously engaged; the number of second protrusions 731 is also two, and they are symmetrically arranged on the two opposite outer sides of the second pin shaft 73. Correspondingly, the number of second grooves 811 is four, which are arranged corresponding to the second protrusions 731, and can allow two second protrusions 731 to be simultaneously engaged, and the clamping is more secure.
[0047] In this specific embodiment, the focus is on Figure 4 A first deformation hole 74 is formed on the first pin shaft 71, and the first deformation hole 74 is formed on the deformation path of the first protrusion 711, so that when the first protrusion 711 rotates relative to the first mounting hole 11, it can be extended and retracted toward the first deformation hole 74; specifically, when the first protrusion 711 slides out of the first groove 111, it extends toward the first deformation hole 74 so that it can continue to rotate relative to the first mounting hole 11, so that when the first protrusion 711 is aligned with the first groove 111, the first protrusion 711 retracts and snaps into the first groove 111.
[0048] The second pin shaft 73 is formed with a second deformation hole 75, and the second deformation hole 75 is formed on the deformation path of the second protrusion 731, so that when the second protrusion 731 rotates relative to the second mounting hole 81, it can be extended and retracted toward the second deformation hole 75. Specifically, when the second protrusion 731 slides out of the second groove 811, it extends toward the first deformation hole 74 so that it can continue to rotate relative to the first mounting hole 11, so that when the second protrusion 731 is aligned with the second groove 811, the second protrusion 731 retracts and snaps into the second groove 811.
[0049] In this specific embodiment, the focus is on Figure 4 The outer periphery of the first rotating shaft 7 protrudes outward to form a first limiting portion 76 and a second limiting portion 77;
[0050] When the first pin shaft 71 is inserted into the first mounting hole 11, the first limiting portion 76 is limited to the inner end surface of the first mounting hole 11, which can effectively prevent the first pin shaft 71 from slipping out of the first mounting hole 11;
[0051] When the second pin shaft 73 is inserted into the second mounting hole 81 , the second limiting portion 77 is limited on the outer end surface of the second pin shaft 73 , which can effectively prevent the second pin shaft 73 from slipping out of the second mounting hole 81 .
[0052] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
