Abstract

The utility model relates to a control button structure for a drain valve of a cistern, a main body section is composed of a button, a button base and a transmission structure. The button is matched with the button base to avoid the phenomenon that the button is stuck in or disengaged from the button base; an action of switching a drain valve can be realized, and previous lever transmission is changed to gear rack transmission; convex grains of a rod cover of the transmission structure are tightly clamped in a quadrate hole with one wide end and one narrow end on the button seat. The whole transmission structure is combined with the button seat closely, and the action of switching the drain valve can be more accurate and flexible with water source saving.

Description

The control button of water tank drain valve

The utility model relates to a kind of button fork, refers to relevant with the control button fork of water tank drain valve especially.

Usually, the dop on the button is because frequent stopping function, wearing and tearing unavoidably.Button is a matched in clearance with cooperating of push-button socket, and button is easy rotation direction in use, and dop departs from the groove of newly opening on the push-button socket, the situation that stuck or button is jumped out push-button socket occurs.The press button draining valve is realized by lever principle, be that power on the button acts on the support arm by a polished rod, support arm is swing upwards, release button, support arm resets to lower swing, because polished rod is the suspended wall state, and very easily distortion and stuck with Zhi Biduan, fork can not be resetted, and draining valve can not fall.

The purpose of this utility model is to provide a kind of control button structure of water tank drain valve of novel structure, whole transmission mechanism and push-button socket are close to and are one, and the upper and lower mobile activity of button is flexible, the fork flexible swinging, guarantee enough strokes, make the work of draining valve normal reliable ground.

For achieving the above object, the technical solution adopted in the utility model is: add a sleeveless jacket at conventional push button seat internal upper part, a step is established in the button bottom, and under the effect of spring restoring force, step pushes up mutually with sleeveless jacket and closes, and line combines with face, and button is stressed evenly.The section of rack that presses the button on the rack bar is meshed with the gear of gear fork, makes fork mention enough height the draining valve gap is opened.Button unclamps, rack bar tip circle face, and under the effect of spring restoring force, whole rack bar homing.By the rack-and-pinion transmission, the gear fork resets, and makes the draining valve normally closed.Rack bar overlaps corresponding groove and the good guide effect of having cooperated of long raised line with bar; Push-button socket is rotated with and has oblong aperture on the screw rod successively, oblong aperture has gradient slightly along hand of spiral, move towards identical by wide gradually narrow direction with screw thread, the bar set upper side is provided with and the corresponding protruding grain of oblong aperture, protruding grain is through narrow tightly being stuck in the hole in the earlier wide back of the shallow slot that leads to oblong aperture, and whole drive structure and push-button socket are close to and are one.

Because above-mentioned button has adopted the top mutually of sleeveless jacket and step to close with button, the line face is in conjunction with having replaced some contact in the past, and button is stressed evenly, and upper and lower action is reliable.Lever transmission in the past changes the rack-and-pinion transmission into, and transmission is more accurate.The tight fit of oblong aperture makes whole press-button structure in conjunction with tight on bar puts protruding grain and the push-button socket, and relative position is firm, and button and fork move more flexibility and reliability.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is further described.

Fig. 1 protrudes the press-button structure three-dimensional exploded view;

Fig. 2 is the push-button socket upward view;

Fig. 3 is the rack bar rear elevation.

Press-button structure as shown in Figure 1 is made up of button 1, push-button socket 2 and drive mechanism 3.Push-button socket 2 internal upper parts are as shown in Figure 2 established a sleeveless jacket 21, and the step 11 of button 1 bottom pushes up under the effect of spring 4 restoring forces and closes in sleeveless jacket 21, and the line face of step and sleeveless jacket makes whole button 1 active force even in conjunction with having replaced point in the past to contact.Section of rack 311 on the rack bar 31 and 321 engagements of the gear of fork 32 front ends, button 1 acts on rack bar 31, does upper and lower swing by rack-and-pinion driving-belt movable pendulum bar 32.Button 1 unclamps, and rack bar tip circle face is under the effect of spring 4 restoring forces, whole rack bar homing, by the rack-and-pinion transmission, the fork end points is returned to minimum point, rack bar 31 and bar cover 33, corresponding groove 312 cooperates with raised line 313, plays good guide effect.Rack bar 31 is fixed in the bar cover 33.Push-button socket 2 is rotated with and has oblong aperture 22 on the screw rod successively, oblong aperture has gradient slightly, move towards identical by wide gradually narrow direction with screw thread, bar overlaps 33 upper ends and is provided with and oblong aperture 22 corresponding protruding grains, protruding grain is through in the oblong aperture on the narrow tight card in shallow groove 23 earlier wide backs that leads to oblong aperture, and whole button is inner to form relatively-stationary positional structure.

Claims

1, a kind of control button structure of water tank drain valve mainly is made up of button, push-button socket and drive mechanism, it is characterized in that: close on button and push-button socket top, and button is connected transmission with draining valve by transmission mechanism, and whole drive mechanism tightly is stuck on the push-button socket.

2, the control button structure of water tank drain valve according to claim 1 is characterized in that: button bottom is established a step and is pushed up mutually with the sleeveless jacket of push-button socket internal upper part and close.

3, the control button structure of water tank drain valve according to claim 1, it is characterized in that: transmission mechanism is made up of rack bar, gear fork, spring lever cover, establish a spring between bar cover and the rack bar, the section of rack of rack bar and fork meshed transmission gear fork move up and down.

4, ask the control button structure that requires 3 described water tank drain valves according to power, it is characterized in that: rack bar in the transmission mechanism and corresponding groove and the raised line established of bar cover, rack bar overlaps fit mutually with bar.

5, the control button structure of water tank drain valve according to claim 1, it is characterized in that: push-button socket is rotated with and is provided with slightly the oblong aperture of gradient on the screw rod successively and moves towards identical by wide gradually narrow direction with screw thread, the drive mechanism bar puts protruding grain correspondingly tightly is stuck in the hole.
