Abstract

The utility model discloses double-row buttons for a drain valve. The double-row buttons for the drain valve comprise a button base, half-row buttons and full-row buttons. The button base is pivoted with a lifting rod through a fixed shaft, and the lifting rod is provided with a thrust face matched with the half-row buttons and full-row buttons to control the double-row buttons. The half-row buttons and full-row buttons are provided with driving columns contacting with the thrust face of the lifting rod. The thrust face of the lifting rod is arc-shaped and the bottom of each driving column is an oblique face which contacts with the arc-shaped face all along. The double-row buttons for the drain valve provided by the utility model are simple in structure, stable in function and low in failure rate and manufacturing cost, and really solve the problem effectively that large aperture water tank drain valves are heavier during application.

Description

Double water valve button

Technical field

The utility model relates to a kind of double water valve button, is specially adapted to the double water valve of heavy caliber.

Background technology

In the prior art, in order to increase drainage speed, strengthen the bath dynamics, obtain the better row's of dashing effect, the dealer has developed the heavy caliber draining valve.Two because of its draining bore is bigger, outfall hermetic unit pressure is bigger for control structure for adopting top-push, so when pressing button and drive draining, feel all lays particular stress on, the operation effort.

Reflect this; Have the dealer to develop a kind of " the double control button of heavy caliber water tank drain valve ", the patent No. is ZL 200620088033.7, and is as shown in Figure 1; Comprise push-button socket 70, partly arrange button 10 and arrange button 20 entirely; On push-button socket 70, be provided with fixed axis 40, socket one argues for the sake of arguing 30 on the fixed axis 40, argues for the sake of arguing 30 to be provided with the contact 3a and be provided with the limited block 3d that argues for the sake of arguing near partly arranging button 10 1 sides of arguing for the sake of arguing; Full row's button 20 is provided with the contact block 2b that argues for the sake of arguing that can contact with the contact 3a that argues for the sake of arguing; Partly arrange button 10 and be provided with the positive stop key 1c that argues for the sake of arguing that argues for the sake of arguing contact block 1b and can contact with the limited block 3d that argues for the sake of arguing that can contact with the contact 3a that argues for the sake of arguing, it is characterized in that: the contact block 1b that argues for the sake of arguing is respectively equipped with projection 1e and 2e with the contact block 2b that argues for the sake of arguing with the 30 afterbody contact positions of arguing for the sake of arguing.This patent is because of projection 1e and 2e design, makes to press the starting stage button to act on 30 the arm of force of arguing for the sake of arguing bigger, and feel is lighter; When argue for the sake of arguing 30 lift after, argue for the sake of arguing and move after 30, it is more and more littler that button acts on 30 the arm of force of arguing for the sake of arguing; But because the buoyancy of water effect, the needed power of lifting is less, therefore whole the firmly more even of process of pressing; Feel is lighter, has solved the heavier problem of feel that prior art exists in the heavy caliber water tank drain valve is used.

But the projection 1e of above-mentioned patent and 2e design have fastidious very much, and projection 1e and 2e are too low, act on not obvious; It is still heavier to press feel, and projection 1e and 2e are too high, when argue for the sake of arguing 30 lift after button act on 30 the arm of force of arguing for the sake of arguing and gap can occur and diminish; Press operation and have some setbacks, functional lability, therefore; This patent structure designing requirement is high, and manufacturing cost is high, is further improved in fact.

The utility model content

The purpose of the utility model is to provide a kind of double water valve button, and it is simple in structure, function-stable, and fault rate and low cost of manufacture solve the heavier problem of feel that exists in the application of heavy caliber water tank drain valve really effectively.

In order to reach above-mentioned purpose, the solution of the utility model is:

Double water valve button comprises push-button socket, partly arranges button and arrange button entirely; On push-button socket, articulate through fixed axis and argue for the sake of arguing, arguing for the sake of arguing has and partly arranges button and cooperate with full row's button and control double stress surface; Full row's button with partly arrange button and be provided with the drive post that can contact with the stress surface of arguing for the sake of arguing; It is characterized in that: the stress surface of arguing for the sake of arguing is a cambered surface, and the bottom of drive post is the inclined-plane that contacts with cambered surface all the time.

Said arguing for the sake of arguing comprises that half row argues for the sake of arguing and full row argues for the sake of arguing, and half row argues for the sake of arguing and full row argues for the sake of arguing is articulated on the push-button socket through fixed axis, and half row argues for the sake of arguing and full row argues for the sake of arguing all has stress surface, and two stress surfaces all are cambered surface; The stress surface that corresponding respectively half row of drive post who partly arranges button and full row's button argues for the sake of arguing and argues for the sake of arguing with full row, the bottom of two drive post all is the inclined-plane.

After adopting said structure, the step surface that the utility model changes prior art projection formation is the inclined-plane, and structure design is simpler, low cost of manufacture.Press in the process, to act on the arm of force of arguing for the sake of arguing bigger pressing the starting stage button, and feel is lighter; After lifting when arguing for the sake of arguing, the inclined-plane still contacts with cambered surface all the time, and button acts on the arm of force of arguing for the sake of arguing and diminishes gradually; Cooperate steadily, smooth and easy, and receive the buoyancy of water effect, the needed power of lifting is less; Whole the firmly more even of process of pressing, feel is lighter, has solved the heavier problem of feel that prior art exists in the heavy caliber water tank drain valve is used really effectively.

Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be described in further detail.
