Description
Technical field
The invention belongs to the valve fittings field that water tank is supporting, relate to a kind of water-stopping structure of toilet suitable Water inlet device for cistern specifically.
Background technology
The water feed apparatus be applicable in water-closet tank existed on the market at present, no matter be by piston type water-stopping structure or back pressure type formula water-stopping structure, the contradictory problems of lever ratio size that all there is the pressure of resistance to piped water and keg float size and argue for the sake of arguing, product will meet can bear larger pipe water supply pressure, particularly present high rise building water supply or some specific region, just require that product can bear higher pressure of supply water.For this reason, adopt often in the prior art and strengthen keg float area to increase buoyancy raising sealing closure, or improve the lever ratio of arguing exactly to improving active force thus realizing high pressure resistant, the most directly impact that this adjustment brings is exactly cause the volume of water feed apparatus to become large, special lateral dimension in water tank increases, the partial structurtes stressing conditions of product becomes large simultaneously, and the destabilizing factor of product is increased.
On the other hand, in the existing design of water feed apparatus two lever structure, also limit this structure and can only be designed to fixed structure, be difficult to realize adjustable requirement, therefore we are when assembling toilet water flushing part, often because side installs incorrect, again must unclamp locking nut adjustment direction locking again again, time-consuming bothersome, product repeated disassembled and assembled is also unfavorable to product (mainly plastic part composition) itself.
Summary of the invention
The present invention is the water-stopping structure that will provide a kind of toilet suitable Water inlet device for cistern, structural element small size, and interlock transmission big lever ratio, reaches the object that can be suitable for high service and can conveniently install and use again.
Above-mentioned purpose of the present invention is realized by such technical scheme, the i.e. water-stopping structure of a kind of toilet suitable Water inlet device for cistern of the present invention, comprise a water intaking valve, water intaking valve end face centre bit installs a ventilation seat stand, and ventilation seat stand face is provided with air vent, it is characterized in that: ventilation seat stand both sides are provided with chimb, chimb clamping one presses dome, top in pressing dome is provided with circular groove, filling one seal washer in circular groove, and circular groove is socketed a spring outward; One is fastened on the lever support on pressing dome, lever support is provided with axis hole, one lever swing arm is movably connected on lever support by rotating shaft and axis hole, the side of lever swing arm is provided with cam surface, cam surface is inconsistent with pressing dome end face, the opposite side of lever swing arm is provided with guide runner, and guide runner and is connected to arguing for the sake of arguing on keg float and connects.
The both sides of above-mentioned pressing dome are hugged empty for connecting window, press dome by the chimb phase clamping of lower window frame with ventilation seat stand, spacing movement in the position limiting structure that lower window frame is formed between chimb and water intaking valve end face, and can automatically reset under the action of the spring.
The both sides of above-mentioned lever support offer Ka Gou, and suitablely, water intaking valve top is also provided with grab, and lever support blocks mutually to be fastened and connected and to be fastened on grab by Ka Gou and presses on dome.
Further preferred version is: above-mentioned lever support is provided with the Connection Block formed by two sheets, and a sheet is provided with axis hole.
Above-mentioned lever swing arm is provided with the rotating shaft matched with axis hole, and rotating shaft side is cam, and cam surface is parabolic shape cambered surface, and cam surface is inconsistent with pressing dome end face, and rotating shaft opposite side is swing arm, and the end of swing arm is provided with guide runner, and guide runner is provided with introducing port.
Above-mentioned top of arguing for the sake of arguing is provided with and connects ring, connects ring and to be connected in guide runner by introducing port peace and can be moved along guide runner.
Further preferred version is also provided with a cover cap, and cover cap clamping lid is located at water intaking valve top, and cover cap side is provided with groove window.
After the present invention adopts technique scheme, compared with prior art tool has the following advantages:
1, lever swing arm structure is adopted, on the one hand, side due to lever swing arm is cam, and cam surface is parabolic shape cambered surface, like this, cam surface is inconsistent by sticking up then producing upper and lower active force along with lever swing arm with pressing dome end face, thus makes pressing dome drive seal washer to move up and down, and realizes hold one's breath sealing, ventilation inlet function.On the other hand, because cam is much smaller relative to the lever arm of force of swing arm, according to lever balance theory, the buoyancy that when cam surface rotates, generation active force produces than keg float is much bigger, there is the effect of small size big lever ratio, but also possess can the feature of self-locking in high-pressure feed water situation, guarantee the withstand voltage stability of product, more can be applicable to use in the complex environments such as high service.
2, cam surface rotate time produce upper and lower active force only with swing arm has a downwarp turn relevant, and air vent is on the central axis of water intaking valve, lever support blocks mutually to be fastened and connected and to be installed in grab by Ka Gou and presses after on dome, because Ka Gou has certain length, lever support can be rotated under the clamping of grab, like this, keg float and assembly of arguing just can move into water valve central axis and to rotate adjustment, therefore, when installing and using, even if after water intaking valve is locked in water tank, also the rotation by lever support regulates keg float, need not repeated disassembled and assembled, reduce wear, facilitate installment and debugging, time-saving and efficiency.
