Description
Technical field
The utility model belongs to the supporting valve fittings field of water tank, relates to specifically a kind of water-stopping structure of toilet suitable Water inlet device for cistern.
Background technology
What exist on the market at present is applicable to the water feed apparatus in water-closet tank, no matter be by piston type water-stopping structure or back pressure type formula water-stopping structure, the contradictory problems of the lever ratio size that all has 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 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, thereby or be exactly to improve the lever ratio of arguing to realize high pressure resistant to improving active force, the most directly impact that this adjustment brings is exactly to 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, existing design at water feed apparatus top lever construction, also limit this structure and can only be designed to fixed structure, be difficult to realize adjustable requirement, therefore we,, when assembling toilet water flushing part, often, because side's installation is incorrect, must again unclamp locking nut and adjust direction again and lock, time-consuming bothersome, itself is also unfavorable to product (being mainly that plastic part forms) for product repeated disassembled and assembled.
Summary of the invention
The utility model is the water-stopping structure that a kind of toilet suitable Water inlet device for cistern will be provided, structural element small size, and interlock transmission big lever ratio, reaches and can be suitable for the object that high service can conveniently be installed and used again.
Above-mentioned purpose of the present utility model is to realize by such technical scheme, it is the water-stopping structure of a kind of toilet suitable Water inlet device for cistern of the utility model, 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, dome is pressed in chimb clamping one, the top of pressing in 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 of pressing on dome, lever support is provided with axis hole, one lever swing arm is movably connected on lever support by rotating shaft and axis hole, one side of lever swing arm is provided with cam surface, cam surface is with to press dome end face inconsistent, 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 joins.
Above-mentioned both sides of pressing dome are hugged empty for connecting window, press dome chimb phase clamping with ventilation seat stand by lower window frame, spacing movement in the position limiting structure that lower window frame forms between chimb and water intaking valve end face, and can under the effect of spring, automatically reset.
The both sides of above-mentioned lever support offer Ka Gou, suitable ground, and water intaking valve top is also provided with grab, and lever support blocks to be fastened and connected to be fastened on grab by Ka Gou mutually to be pressed on dome.
Further preferred version is: above-mentioned lever support is provided with the Connection Block being formed by two sheets, and a sheet is provided with axis hole.
Above-mentioned lever swing arm is provided with the rotating shaft matching with axis hole, and rotating shaft one side is cam, and cam surface is parabolic shape cambered surface, and cam surface is with to press dome end face inconsistent, 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.
The above-mentioned top of arguing for the sake of arguing is provided with and connects ring, connects ring and is pacified and be connected in guide runner and can move along guide runner by introducing port.
Further preferred version is to be also provided with a cover cap, and cover cap clamping lid is located at water intaking valve top, and cover cap one side is provided with groove window.
The utility model adopts after technique scheme, and compared with prior art tool has the following advantages:
1, adopt lever swing arm structure, on the one hand, because a side of lever swing arm is cam, and cam surface is parabolic shape cambered surface, like this, cam surface with press that dome end face is inconsistent drives seal washer to move up and down along with the sticking up then produce upper and lower active force of lever swing arm thereby make to press dome, realize the sealing of holding one's breath, ventilation inlet function.On the other hand, because cam is much smaller with respect to the lever arm of force of swing arm, according to lever balance theory, cam surface produces active force while rotating more much bigger than the buoyancy of keg float generation, the effect with small size big lever ratio, but also possess can self-locking in high-pressure feed water situation feature, guarantee to be more applicable to the withstand voltage stability of product use in the complex environments such as high service.
2, when cam surface rotates, produce upper and lower active force and only turn relevant with having a downwarp in swing arm, and air vent is on the central axis of water intaking valve, after lever support is blocked mutually and is fastened and connected and is installed in and presses on dome by Ka Gou and grab, because Ka Gou has certain length, lever support can be rotated under the clamping of grab, like this, keg float and the assembly of arguing just can move into the adjusting that rotates of water valve central axis, therefore, when installing and using, even if after water intaking valve is locked in water tank, also can regulate keg float by the rotation of lever support, needn't repeated disassembled and assembled, reduce wear, facilitate installment and debugging, time-saving and efficiency.
