Description
Technical field
The utility model relates to the folding lid mechanism of pressure cooker, and particularly a kind of convenient rotary flip-open cover mechanism of pressure cooker that uses belongs to the improvement technology that has the pressure cooker open and close lid mechanism now.
Background technology
Connect into integral body by the pot tooth that cooperatively interacts mostly between the pot cover of existing pressure cooker and the pot body, during use, fasten pot cover and pot body by rotation, make pot cover and pot body be separated into two independently parts by reverse rotation again, need to seek a suitable position this moment and place this pot cover, bring great inconvenience to the user.Because between pot cover and the pot body is to fasten by rotation, its pot cover can not be as present press fastening type electric cooker direct employing flip-shell structure, in order to make pot cover still link together when opening with the pot body, and can realize that flip-shell uncaps, the application's applicant at application number is: 200520054993.7, name is called: proposed a kind of electric pressure cooking saucepan that has flip-shell folding lid mechanism in a kind of patent application of novel voltage power pot, it is at the external sidewall of pot circumferential guide rail to be set, the pot cover circumferential edges is provided with fastener, described fastener is provided with the through hole that is slidingly matched with guide rail, fastener is sleeved on the guide rail by through hole, fastener slides along guide rail during the pot cover rotation, fastener is that axle rotates with the guide rail during pot cover upset, realize the relative rotation and the folding of overturning between pot cover and the pot body like this, pot cover links together when opening with the pot body, uses very convenient.But also there is following shortcoming in this technical scheme: all can overturn up or down in the optional position of pot cover on guide rail, so after the upset of uncapping, if the pot cover fastener has slip along guide rail, at this moment, pot cover still can be under the guide rail overturn cover, but overlapping has appearred in a pot tooth between pot cover and the pot body at this moment, pot cover pot tooth can't buckle into a pot body pot tooth, can not realize the locking of pot cover, must dig pot cover again and adjust its position, again pot cover is covered, comparatively trouble; After the upset, the pot cover fastener a small amount of the slip occur along guide rail if uncap, and this moment is under the pot cover overturn cover, pot cover pot tooth also may occur and pot cover occur with the pot body mutual jam-packed of pot tooth and can not be fastened on pot body, is difficult to the card lid phenomenon of opening again again.
The utility model content
The technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of pressure cooker rotary flip-open cover mechanism, when making pot cover pass through Unscrew with the pot body, and the turning certain angle of pot cover, pot cover still links together with the pot body simultaneously; Pot cover need cover with a pot body and with pot cover overturn cover following time, can guarantee pot cover in accurate position, and pot cover pot tooth can be staggered fully with pot body pot tooth, realizes fastening by rotation smoothly.
The technical scheme that realizes the utility model purpose is: the utility model includes pot cover and pot body, be respectively equipped with some pot teeth that mutual rotation cooperate with pot on the body at pot cover, on the lateral wall of pot body upper edge, be provided with two boss, be provided with circumferential guide rail between two boss, one end of guide rail is fixed therein on the boss, the other end of guide rail is a free end, the pot cover circumferential edges is provided with fastener, fastener is provided with the through hole that can be corresponding with guide rail and is slidingly matched, through hole is provided with opening, between the free end of guide rail and the pot body below it, be fixed with limited block, the thickness of limited block is less than the width of fastener through hole upper shed, and the distance between the boss of limited block and fixed guide is not less than the width of fastener.
A/F on the above-mentioned fastener through hole is less than the guide rail radial dimension, in order to avoid in the pot cover switching process, and fastener slippage from the guide rail.
Between the boss of above-mentioned limited block and fixed guide is the width that equals fastener apart from optimum implementation.
Pot cover unloads from guide rail and cleans for convenience, and the free end of described guide rail is not less than the width of fastener to the distance of another boss that is not fixed with guide rail.
The cross section of described guide rail can be circular or oval or other shapes.
The beneficial effects of the utility model are: in the time of need uncapping, the rotation pot cover turns on the boss and the position between the limited block of guide rail stiff end fastener, pot tooth on pot cover and the pot body staggers mutually fully, can unclamp pot cover, making pot cover is that axle realization upset is uncapped with the guide rail, and a pot cover and a pot body are linked together.In the time of need locking pot cover,, promptly be between the boss and limited block of guide rail stiff end, then directly cover pot cover down, rotate pot cover again pot tooth on pot cover and pot body is fastened mutually, the interior sealing of realization pot if the pot cover fastener just in time is on the position of overturning when uncapping; If the pot cover fastener has departed from the boss of guide rail stiff end and the position between the limited block, with the guide rail rotation of axle then owing to limited block has stopped fastener, pot cover can not overturn cover under, need removable fastener on the boss and the position between the limited block of guide rail stiff end, again with under the pot cover overturn cover, be that a rotatable pot cover and the pot tooth of pot on the body of making fastens mutually, realize the sealing in the pot.Like this as long as pot cover is not subjected to stopping under the energy overturn cover of limited block, just can guarantee that pot cover is in accurate position, pot cover pot tooth can be staggered fully with pot body pot tooth, smoothly realize fastening, avoided in the prior art pot cover under non-accurate position also can overturn cover and can not realize that pot tooth fastens even the phenomenon of Ka Gai by rotation.When needs clean pot cover, only need after uncapping, the pot cover fastener is slided along guide rail, allow the opening on the fastener through hole pass limited block, unload pot cover thereby just fastener can be withdrawed from from the free end of guide rail.Therefore the utlity model has the characteristics accurate, easy to use, simple in structure, handling ease of covering of closing, can effectively avoid the He Gai position to be forbidden and can not realize the phenomenon of pot tooth fastening even Ka Gai, guide rail is the half structure in addition, therefore can save guide material, reduces product cost.
