Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model be to this area provide a kind of push-button type renovate interior push button bowl cover so that it is the press-button structure solving to renovate in existing like product setting is not good enough, operation, produce comparatively inconvenience technical problem.Its objective is to be achieved through the following technical solutions.
One renovates interior push button bowl cover, and one end renovated of this bowl cover is hinged with one end of cage, and hinged place is provided with torsion spring, and cage is provided with apopore；Its structural design is characterized by the apopore of described cage and is provided with drinking-water part, the interlayer place of drinking-water part is provided with drinking-water hole and pore, drinking-water part is provided with drinking-water lip, and drinking-water lip is positioned at the cover side drinking-water part edge of the cage hinged place symmetry other end, and the drinking-water lip of drinking-water part is symmetrically arranged on two with lock ear；The place of renovating that drinking-water part internal diameter is corresponding is provided with the cage knob groove of projection, cage knob groove communicates with the through hole renovated, cage knob is arranged in the cage knob groove renovated, cage knob be symmetrically arranged on two with latch hook, the push button end portion of cage knob is stretched out in the through hole renovating cage knob groove place, and cage knob is offseted with the cage knob groove renovated by spring；Renovating when fastening with cage, the lock ear of drinking-water part fastens with the latch hook of cage knob.Thus renovating and under cage closed mode, being stretched into by finger in the through hole renovated, promote the cage knob in cage knob groove, make the latch hook of cage knob depart from the lock ear of drinking-water part or fasten, renovate and open or fasten.
The lock ear of described drinking-water part is provided with end triangular in shape and hook portion, and the latch hook of cage knob is respectively equipped with gathering sill and hooked scarf, and the lock ear of drinking-water part fastens with the gathering sill of latch hook, and is limited in hooked scarf.Said structure is a kind of latch hook and the concrete structure of lock ear, and it also can adopt existing homogeneous structure, can realize latch hook and close with lock earclip；As: the lock ear of L-shaped and latch hook structure are mutually locked.
The described cage side renovated is provided with and seals lid, seals to cover to be fixed on by lid set and renovates, and the muscle post circle that lid overlaps with cage knob groove external diameter fastens, and the cup side drinking-water piece bores mouth external diameter of cage is provided with sealing ring.Renovate when fastening with cage, seal the internal diameter of lid and drinking-water part, and the drinking-water hole of drinking-water part and port sealing；When this bowl cover and cup screw, the rim of a cup inner diameter seal of sealing ring and cup.
The hinged end of described cage is positioned at the separation platform that side is protruding, and this end renovated is provided with oblique flat key limit, and the separation platform of the flat key limit renovated and cage is fitted when renovating closedown.Consequently facilitating the torsion spring isolation of this bowl cover hinged place, and renovate and cage further sealing when closed.
This utility model reasonable in design, uses operation and produces easy to assembly, and sealing thermal insulation is effective；The bowl cover being suitable as water tumbler uses, and the structure of like product is improved.
