Abstract

The utility model relates to a control press button for a drain valve of a water tank, which is composed of a press button head, a press button seat, a lifting rod, a lifting seat, and a hinging branched chain position shifting claw connecting supporting arm, wherein, the press seat is provided with a position limiting guide foot, and a supporting ring thereof is connected with the lifting with a threaded rabbet; the inside of the lifting seat is provided with the lifting rod and a spring, and a guide salient angle is matched with an axial groove of the lifting rod to carry out the position limitation; a position shifting claw connected with the supporting arm is arranged in a hole on the bottom surface of the lifting rod; the lifting is driven to move a compression spring downwards by pressing the press button head, the position shifting claw is caused to move downwards to enable the supporting arm to be tilted upwards to open the a drain valve, and inversely, the drain valve is closed. The touch and the press are flexible at the time of use, the water can be saved, and the lifting rod is not easy to abrade.

Description

The water tank drain valve control button

The utility model is about a kind of water tank button, more particularly about a kind of water tank drain valve control button.

The employed control button kind of existing water tank drain valve is more, and the top-push draining valve control button that split water tank is wherein used because the finger pressure head that touches the button, directly acts on spring and presses down on the hinge institute chord arm to slide bar and lift, and allows the draining valve flushing that discharges water.But because the following direct effect spring of button shell, exert oneself just can cause transmission awkward not smooth when inhomogeneous, it is big that slow in reacting and hinge displacement piece has abrupt change generation noise.

The purpose of this utility model is to overcome the weak point of above-mentioned technology, and a kind of spring base that impels the spring homogeneous deformation of pushing is provided, and preparation elevating lever and slick and sly switching hinge are dialled the water tank drain valve control button of plug.

Task of the present utility model is achieved in that a kind of water tank drain valve control button, button head 1 is arranged in its member, push-button socket 2, lock dress nut, spring 6, elevating lever 3, elevating bracket, the DIP pawl that connects rectangle support arm 8 is housed on the hinge 10, two spacing guiding pin legs that it is characterized in that button head 1 are longer than the lower edge periphery, female support ring 13 external push-button sockets 2, be shaped on circumference boss spring base 4 on the elevating lever 3, and be shaped on side direction gathering sill 11 vertically, be shaped on rectangular through holes 5 on top, bottom surface, have external screw thread on the elevating bracket 7 and only detain platform, in have shoulder hole to support to put spring, there is guiding salient angle 12 its neck below, what connect support arm 8 is that oval head DIP pawl 9 is to be located on the hinge 10, DIP pawl 9 inserts in through hole 5, salient angle 12 inserts in gathering sill 11, and the spring base that spring 6 is installed on elevating lever 3 is against for 4 times on the shoulder hole step of elevating bracket 7, and elevating bracket 7 links with screw thread and support ring 13, elevating lever 3 upper ends are against the inner top surface central authorities of button head 1, chord plate 14 under the control button.Salient angle 12 can be that independent component and elevating bracket 7 link, and support arm 8 cross sections can be oval.When referring to press button 1, promptly by the spring 6 that is pressed under the elevating lever average rate on elevating bracket 7 stepped holes, DIP pawl 9 of through hole 5 start slynesses is descending on it simultaneously, makes support arm 8 perk arm ends draw back water discharging valve around hinge 10.After loosing one's grip, recover spring 6 deformation forces, button is restored.

The advantage that the utility model is compared with prior art is: owing to be that the elevating lever upper end is against the button head center, two pairs of guiding pin guiding in the spacing lifting of push-button socket opening part are arranged, the guiding of gathering sill and salient angle, and spring is to pass elevating lever, make that the pressing power transmission is steady, highly sensitive, and with pressing the power size, support arm upwarps and highly can change draining and begin to speak, be suitable for using water wisely, the spring homogeneous deformation can reduce transmits the start noise, and reduces wear, and increases the service life, button head removes following section and axially shortens, alleviate elevating lever and support useless gravity, when the pressing button, face K is resisted against the support ring upper surface with its lower edge, the down stroke of having controlled button head does not make spring because of the stressed excessive permanent deformation that produces fatigability, influences reliable service behaviour.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is the A-A sectional view.

Fig. 3 is that axle of the present utility model is surveyed disassembled schematic.

Among Fig. 1 to Fig. 3: 1. button head 2. push-button sockets 3. elevating levers 4. spring bases 5. rectangular through holes 6. springs 7. elevating brackets 8. support arms 9. DIP pawls 10. hinges 11. gathering sills 12. guiding salient angles 13. support rings

Referring to Fig. 1,3, a kind of water tank drain valve control button, button head 1 is installed on the push-button socket 2, two pairs of guiding toes can slide up and down in its open slot, the lower end built-in hold pushing out ring 13 of push-button socket 2, it can prop up button head 1 lower edge K face and can not drop out, and ends elevating bracket 7 threaded connections of detaining with internal thread and band, and elevating bracket has ladder platform spring base instead for 7 times.The gathering sill 11 that has guiding salient angle 12 and elevating lever 3 referring to Fig. 2 cooperates, have on the elevating lever 3 of boss spring base 4 suit and spring 6, on withstand on the spring base 4, be against down on the ladder platform of elevating bracket 7, on its bottom surface, have rectangular through holes 5 in addition, DIP pawl 9 inserts in through hole 5, and is installed on the hinge 10 with support arm 8 bindings.It is compact that each component is connected, and transmission is reasonable, and working stability is reliable, and elevating lever is difficult for mill, helps using water wisely.
