Description

Technical Field

[0001] The invention relates to a low-friction and labor-saving double-drain valve lifting control mechanism. Background Art

[0002] Chinese patent CN203569658U discloses a double drain valve inner core tube starting device, including a button seat, a body, a half-row button, a full-row button, a half-row float, a full-row float, an inner core tube and a lever; the half-row float, the full-row float and the inner core tube are assembled in the body to form a half-row structure and a full-row structure; the button seat is installed on the body, and the half-row button and the full-row button are assembled on the button seat; at least two groups of levers are installed in the body, and are symmetrically arranged, one end is abutted against the half-row button and the full-row button, and the other end is connected to the inner core tube through a pull rod. The characteristic of this structure is that a pair of pull rods can reduce the drainage pressing force and reduce the friction between components. However, due to the rotation of the lever assembly during lifting, the pull rod must continuously undergo vertical displacement changes and horizontal left and right displacement changes at the inner core tube connection position, which will still generate friction. In severe cases, jamming will occur. This makes flushing and draining pressure laborious, and constant friction also causes components to be easily damaged, shortening the service life of components. Summary of the invention

[0003] The purpose of the present invention is to provide a low-friction and labor-saving double drain valve lifting control mechanism in view of the problems existing in the existing drain valve lever assembly structure.

[0004] The objective of the present invention is achieved in this way: a low-friction and labor-saving double drain valve lifting control mechanism is arranged in a drain valve body, a half-row button and a full-row button reset by a spring are installed on the button seat of the drain valve body, a half-row float and a full-row float which are linked to cooperate with the lifting control mechanism to drain water and shut off water are arranged in the drain valve body, and a half-row structure and a full-row structure are formed by assembling the half-row float, the full-row float and the inner core tube in the drain valve body; the lifting control mechanism is equipped with a pair of symmetrically arranged lever assemblies; one end of the lever assembly abuts against the half-row button and the full-row button, and the other end of the lever assembly is slidably connected to the slide groove of the inner core tube through a roller, and when the half-row button or the full-row button is pressed, the inner core tube is lifted by rotating the lever assembly and sliding the roller, so that the water sealing sheet connected to the lower part of the inner core tube is lifted to drain water.

[0005] The invention has a pair of cavities on the upper part of the inner core tube, the cavities form a structure for the roller end of the lever assembly to be directly inserted, and the cavities provide a sliding groove and a shoulder structure for the roller.

[0006] In the present invention, one end of the lever assembly is in contact with the half-row keys and the full-row keys, and the other end is slidably connected to the slide groove of the inner core tube through a roller. There is no horizontal left-right displacement change of the pull rod. When the inner core tube is lifted, the inner core tube will not tilt, will not generate friction with other components, the pressing force is reduced, and will not damage the inner core tube and other components.

[0007] The present invention, through the above-mentioned simple sliding lifting structure, truly realizes the vertical left-right balanced lifting of the lifting mechanism, thereby ensuring that the up and down movement of the lifting rod is vertical, reducing friction, and the swinging of the pendulum is flexible, thereby extending the service life of the product and reducing the failure rate.

[0008] The present invention is further described with reference to the following embodiments and accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0011] Reference Figures 1 to 9 The present embodiment is a low-friction and labor-saving double drain valve lifting control mechanism, which is arranged in a drain valve body 1. A half-row button 3 and a full-row button 4 reset by a spring are installed on a button seat 2 of the drain valve body. A half-row float 5 and a full-row float 6 are provided in the drain valve body to cooperate with the lifting control mechanism for draining and closing water. The half-row float, the full-row float and the inner core tube 7 are assembled in the drain valve body to form a half-row structure and a full-row structure; the lifting control mechanism is equipped with a pair of symmetrically arranged levers Component 8; one end of the lever component is in contact with the half-row buttons and the full-row buttons, and a pair of cavities 11 are provided on the upper part of the inner core tube, the cavity forms a structure for the roller end of the lever component to be directly inserted, and the cavity provides a slide groove and a shoulder structure for the roller; the other end of the lever component is slidably connected to the slide groove of the inner core tube through the roller 9, and when the half-row buttons or the full-row buttons are pressed, the lever component rotates and the roller slides to control the lifting of the inner core tube, so that the water sealing sheet 10 connected to the lower part of the inner core tube is lifted to drain water.

[0012] Reference Figures 5 to 9 When flushing the whole row, press the full-row button 4, and the inner core tube 7 is lifted upward through the lever assembly 8 until the full-row convex point 12 abuts against the full-row bracket 13 linked with the full-row float 6. At this time, the inner core tube is limited and the water-sealing piece 10 is lifted to realize flushing and drainage. When the water level drops to the full-row float, the full-row float links the full-row bracket to deflect under the action of gravity, that is, the full-row bracket is stretched outward, the inner core tube loses its abutment and falls back to its original position, and the water-sealing piece falls back to the drain outlet to complete the full-row flushing.

[0013] The schematic diagram of half-row flushing is omitted. When half-row flushing is performed, the half-row button is pressed, and the inner core tube is driven to rise upward through the lever assembly until the half-row protrusion 14 abuts against the half-row bracket 15 linked to the half-row float barrel. At this time, the inner core tube is limited and the water-sealing piece is lifted to realize flushing and drainage. When the water level drops to the half-row float barrel, the half-row float barrel links the half-row bracket to deflect under the action of gravity, that is, the half-row bracket expands outward, the inner core tube loses its abutment and falls back to its original position, and the water-sealing piece falls back to the drain outlet, completing the half-row flushing.
