Description
Technical field
The present invention relates to pressure cooker technical field, especially a kind of lock cover of pressure cooker structure.
Background technique
By taking current electric pressure cooking saucepan as an example comprising pot and pot cover, pot body inner top, which is circular layout, has bumps alternate
Pot tooth, pot cover inner wall correspond to pot tooth equipped with button bit, by rotating pot cover button bit are in below the pot tooth of protrusion, realize pot cover
With lid snapping, conversely, pot cover can be dug or open when button bit is rotated in company with pot cover to recessed pot tooth.Due to pot
Interior air pressure is uncapped dangerous property when higher, and therefore, existing pressure cooker has a set of self-locking mechanism, self-locking mechanism include with
In pot air pressure change and float up and down air bearing valve, slide laterally the lock pin component being arranged in pot cover, lock pin component one end
The pot tooth surface of pot body is against, the lock pin component other end extends at air bearing valve, under normal circumstances, if air pressure is lower in pot
(safe opening air pressure), air bearing valve will not stop lock pin component, when pot cover Unscrew, lock pin component along pot body pot tooth surface from
By activity, do not influence to uncap；Conversely, air bearing valve stops lock pin component, so that lock pin component cannot edge when air pressure is excessively high in pot
Pot body pot tooth surface is move freely, therefore pot cover cannot rotate, so that cannot uncap.Certainly, described above is theoretical shape
State, but actually still there is some potential safety problems in the structure, because being certainly existed between air bearing valve and lock pin component certain
Diastema (if will be stuck without diastema air bearing valve), even if in pot in anticyclonic situation, if acting on pot cover
Rotation uncap active force it is larger when, lock pin component can overcome the resistance of air bearing valve, and change the state of air bearing valve, can be this
It is unfavorable for uncapping in the state of uncapping, to bring huge security risk, it is therefore desirable to improve the structure.
Summary of the invention
The purpose of the present invention is to provide a kind of simple and reasonable for structure, it is safe and reliable, at low cost, convenient and simple for operation easily
Lock cover of pressure cooker structure guarantees that electric pressure cooking saucepan is unable to violence in use and uncaps, but can uncap with unification key, with gram
Take the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of lock cover of pressure cooker structure, including pot and pot cover, pot body top annular are disposed with multiple lower pot tooths, pot cover bottom
Portion is equipped with upper pot tooth, and upper pot tooth is consistent with lower pot tooth quantity, it is characterised in that: the lower pot tooth two sides are respectively equipped with a forward direction
Side and a reversed side, the reversed side of pot tooth is to stop side, positive side and remaining reverse side under wherein at least one
While being guiding bevel edge；It is also slid laterally in the pot cover equipped with lock pin, lock pin is located at corresponding with the lower pot tooth on side is stopped
Upper pot tooth one end above place, and lock pin direction pot body center at；When pot cover and pot body are closed, each upper pot tooth is snapped onto
Lower pot tooth bottom, lock pin are mutually kept off with the blocking side accordingly, and the pot cover outer surface, which is equipped with, leaves blocking for controlling lock pin
The unlock control on side.
The purpose of the present invention can also be solved using following technical measures:
As more specific scheme, the blocking side is straight flange, and straight flange is directed toward pot body center.Side is stopped to be not limited to directly
Side.
As further embodiment, the unlock control is Self-resetting button, and lock pin is connect with connecting rod, and connecting rod extends to certainly
Reset button installation place, Self-resetting button is by driving lock pin movement after touching connecting rod.
The Self-resetting button includes button ontology and first back-moving spring, and the limit of button ontology is movably arranged on pot cover
On, the first back-moving spring is equipped between button ontology and pot cover, button ontology is equipped with the mandril for touching connecting rod.
The button ontology is movably arranged on pot cover vertically, and connecting rod and mandril are driven by inclined-plane and are cooperated.
The connecting rod corresponds to mandril equipped with voussoir, and mandril lower end is equipped with ejection inclined-plane and voussoir transmission cooperates.
The pot cover includes outer cover and inner cover, and the upper pot tooth is arranged in inner cover inner circumferential；The lock pin is directed toward pot body center
One end be equipped with ballhead, lock pin backwards to pot body center one end be equipped with positioning pin, outer cover correspond to positioning pin be equipped with first through hole,
Inner cover corresponds to lock pin and is undertaken in first through hole and in the second through-hole respectively equipped with the second through-hole, positioning pin and lock pin.
Second back-moving spring is arranged on the positioning pin, second back-moving spring is crimped between outer cover and connecting rod.
As further embodiment, the cover top portion is equipped with handle, and button ontology is arranged on handle, in order to user
Operation.
The pot nside is equipped with the open cavity in top, inner casing is equipped in cavity, inner casing top extends at the top of pot body, interior
Shell top is equipped with flanging；Flanging periphery bumps are alternate, and protrusion is formed as the lower pot tooth.
As more specific another scheme, described positioning pin one end is stretched out outside pot cover through first through hole and is connect with pull handle.When
When lock pin is mutually kept off with blocking side, by holding pull handle outward, lock pin could be made to leave and stop side, be just able to rotate pot cover at this time.
Beneficial effects of the present invention are as follows:
(1) such lock cover of pressure cooker structure is when rotating in the forward direction pot cover realization locking closure operation, due to lock pin and lower pot tooth
Lead-in chamfered contact, so can be with tooth surface shape movement of cooking；After pot cover and pot body snapping, the resistance of lock pin and lower pot tooth
Rib is mutually kept off, and lock pin cannot be along stopping side to be slided, and therefore, pot cover cannot reversely rotate unlock, be needed at this time through unlock control band
Pendulum lock pin, which exits, stops side, can carry out pot cover and reversely rotate operation, realize unlock, thus when avoiding that air pressure is excessively high in pot,
Because directly firmly rotating pot cover and pot cover being caused to open by mistake bring security risk, the safety used is improved.
(2) shape that such lock cover of pressure cooker structure only slightly modifies its lower pot tooth on the basis of existing pressure cooker is come
It realizes, structure is very simple, and cost is extremely low, but greatly improves safe effect.
(3) the button ontology of such lock cover of pressure cooker structure is arranged on pot cover handle, holds pot cover handle, thumb can
It pins button ontology simultaneously, carries out a key and uncap operation, manipulation is easy-to-use.
