Definitions

  • the switch (button switch or wrench switch) of the drain valve for the existing toilet is directly locked on the water tank cover through thread connection, and can be directly disassembled simply by rotating the switch body without the aid of special tools.
  • the drain valve switch used at home is safe and will not be disassembled and taken away at will.
  • the switch installed in the public place is likely to be damaged or unscrewed and taken away by someone as it is very simple and easy to disassemble it, making it impossible to drive the drain valve in the water tank, and thereby resulting in the problem of extremely poor public health due to the toilet failure.
  • a drain valve switch with a clutch structure including a switch body, a switch mounted on the switch body, a thread member, and a linkage member movable between a first position and a second position; when the linkage member is located at the first position, the switch body drives the thread member to rotate through the linkage member, and the switch body is locked or unlocked through the thread member; when the linkage member is located at the second position, the linkage member disconnects the linkage between the switch body and the thread member, and the switch body is unable to be locked or unlocked through the thread member.
  • the linkage member When the drain valve switch is assembled or disassembled, the linkage member is first placed at the first position, the switch body is made to link the thread member through the linkage member, and the thread member is driven to rotate when the switch body is rotated, thus locking or unlocking the entire drain valve switch on an installation position of a water tank or another device.
  • the linkage member In normal use, the linkage member is adjusted to the second position. At this time, the linkage between the switch body and the thread member is disconnected, and the thread member cannot be driven to screw out of the installation position even if the switch body is rotated.
  • the disassembly method for the drain valve switch is unique and is different from the assembly method for the drain valve switch available on the market, thus ensuring that the drain valve switch is unlikely to be disassembled.
  • the thread member and the switch body are rotatably mounted together, and the linkage member is movably mounted on the switch body or on the thread member.
  • the linkage member includes a driving portion, and when the switch is located in an initial position, the switch covers the driving portion; the switch leaves the initial position after being driven and exposes the driving portion for driving, so that the linkage member moves between the first position and the second position.
  • the linkage member is set in a hidden position, making it more difficult for a person who does not know the corresponding structure to completely disassemble the drain valve switch.
  • the thread member is provided with a linkage fitting portion
  • the linkage member is provided with a corresponding linkage portion; when the linkage member is located at the first position, the linkage portion and the linkage fitting portion are in circumferential transmission fit; when the linkage member is located at the second position, the linkage portion is separated from the linkage fitting portion.
  • the switch is a button
  • the switch body is a button body
  • an inner cavity with a top opening is formed inside the button body, and the bottom of the inner cavity is provided with a through hole; both the button and the linkage member are movably installed in the inner cavity, and the thread member rotatably penetrates through the through hole and is capable of being axially limited, and the linkage fitting portion on the thread member is located in the inner cavity, and a thread portion on the thread member is located outside the button body.
  • the linkage member moves between the first position and the second position along the axial direction of the thread member; when the thread member is rotated, on a plane perpendicular to the axis of the thread member, a projection trajectory drawn by the linkage fitting portion partially overlaps with a projection of the linkage portion; when the linkage member is located at the first position, the linkage portion and the linkage fitting portion align in the axial direction of the thread member, and when the switch body is rotated, the linkage portion abuts against the linkage fitting portion to form circumferential transmission fit; when the linkage member is located at the second position, the linkage portion and the linkage fitting portion misalign in the axial direction of the thread member, and the thread member is able to rotate freely relative to the linkage member.
  • the linkage member includes an adjusting piece and a spring pin, and the spring pin forms the linkage portion; a periphery of a portion of the thread member located inside the switch body is provided with a boss, and the boss forms the linkage fitting portion.
  • the adjusting piece is movably mounted inside a strip groove formed in the switch body, and the length direction of the strip groove is parallel to the axis of the thread member, the spring pin is elastically supported between the adjusting piece and the switch body through an elastic member; the adjusting piece and a side wall of the strip groove are respectively provided with a retaining protrusion and a retaining groove; when the linkage member is located at the first position, the adjusting piece is located at a position where the retaining protrusion and the retaining groove are separated from each other, and the spring pin and the boss are in circumferential transmission fit under the influence of the elastic member, when the linkage member is located at the second position, the adjusting piece is located at a position where the retaining protrusion and the retaining groove are in retaining fit, and the adjusting piece overcomes the elastic force of the elastic member so that the spring pin and the boss misalign in the axial direction of the thread member; and a driving portion for manual or tool driving is disposed on a position of the adjusting piece close
  • the thread member has an end located in the inner cavity and having an end diameter greater than a diameter of the through hole; and the drain valve switch with a clutch structure further includes a thread member retaining cover, where the thread member retaining cover is provided with a thread hole corresponding to a thread of the thread member, the thread member retaining cover is screwed into a portion of the thread member extending out of the switch body, and the thread member is relatively rotatably mounted on the switch body through the thread member retaining cover and the end of the thread member located in the inner cavity.
  • the thread member is a hollow structure open at both ends; a transmission rod penetrates through the thread member and has an end connected to the switch.
  • a drain valve includes the drain valve switch with a clutch structure.
  • a drain valve switch with a clutch structure, and a drain valve of the present disclosure both include a switch, a switch body, a thread member and a linkage member with a linkage function; a connection relationship between the switch body and the thread member can be switched by changing a position of the linkage member; when the linkage member is located at a first position so that the switch body and the thread member are in a linkage relationship, the thread member is driven by rotating the switch body, to achieve the locking and unlocking of the thread member, thereby realizing the locking or unlocking of the switch body; when the linkage member is at a second position so that the linkage relationship between the switch body and the thread member is disconnected, the switch body and the thread member are relatively independent of each other, that is, the switch body cannot be locked or unlocked through the thread member, and the installed thread member cannot be screwed out even if the switch body is rotated, ensuring that the entire drain valve switch cannot be easily removed
