[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0022] In the present application, unless specifically defined and limited otherwise, the terms "mounting", "connection", "connecting", "fixing" and the like should be interpreted broadly, for example, can be fixed connection, can also be detachable connection, or integrated; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

Moreover, the first feature "on", "above" and "above" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "under", "below" and "below" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0024] Embodiments

[0025] Referring to Figs. 1-2 As shown in the drawings, the utility model discloses a quick installation's drain valve base, including base main part, the base main part bottom extension forms sleeve 101, sleeve 101 sets up rubber sealing ring 102, wherein, the height of sleeve 101 is X, the height of rubber sealing ring 102 is Y, X greater than Y, the height of sleeve 101 is greater than the height of rubber sealing ring 102, can only ensure that rubber sealing ring 102 will move along with sleeve 101 and compress.

[0026] Referring toFigs. 2-6 As shown, the fixed rod 104 is arranged above the sleeve 101 inside the base body, the middle of the fixed rod 104 is provided with a mounting hole 1041, the bottom of the rubber sealing ring 102 is mounted with the movable ring 103, and the bolt passes through the mounting hole 1041 to connect the movable ring 103. Specifically, the inner ring of the mounting hole is provided with a fixed protrusion, the rubber sealing ring 102 is circumferentially provided with an annular mounting groove, and the fixed protrusion is clamped in the annular mounting groove, so that the movable ring 103 is mounted at one end of the rubber sealing ring 102 and compresses the rubber sealing ring 102 along with the movement of the movable ring 103 along the sleeve 101.

[0027] Further, the sleeve 101 is symmetrically provided with a reverse U-shaped guide groove 1011 on both sides, the middle of the movable ring 103 is fixed with a cross rod 1031, the middle of the cross rod 1031 is provided with a threaded hole 1032, when the bolt is tightened, the movable ring 103 moves upward, the cross rod 1031 is placed in the two guide grooves 1011 and can move upward along the guide grooves 1011, the guide grooves 1011 provide a space for the cross rod 1031 of the movable ring 103 to avoid, and on the other hand, the movable ring 103 cannot move upward due to the rotation of the bolt during the upward movement.

[0028] In the embodiment, the rubber sealing ring 102 includes a gasket 1021 at the upper end, and the middle of the rubber sealing ring 102 is protruded. Specifically, when the locking bolt is tightened, the base will press the gasket 1021 on the closestool to play a sealing role, when the movable ring 103 pushes the rubber sealing ring 102 upward, the rubber sealing ring 102 will expand outward from the protruding position in the middle, so that the movable ring 103 presses the expanded rubber sealing ring 102 on the closestool to play a sealing and mounting role.

[0029] In addition, the base body is circumferentially provided with a plurality of rib plates above the sleeve 101, because the locking bolt drives the movable ring 103 to move upward and press the rubber sealing ring 102 on the base body, therefore, the base body is under great stress, and the rib plate provides sufficient strength support to prevent the base body from being deformed by hand pressure.

[0030] The above only describes preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
