Abstract

Disclosed is a safety device for the cover of a pressure cooker, in particular to a safety device for the cover of a lockable electric pressure/common dual-purpose cooker, belonging to components for an electric cooker. The utility model comprises a lock(2) and an inner crimping(1)on the cooker body; the outermost edge of the lock(2) is provided with an upward raised edge; the inner crimping(1)on the cooker body takes the shape of a hook into which the upward raised edge on the outermost edge of the lock(2) is inserted so as to be buckled with the hook of the inner crimping(1)of the cooker body; the cooker is the same with common pressure cookers in appearance; the utility model is simple in structure, easy to operate and is safe and convenient to use; therefore the utility model is suitable for lockable electric pressure/common dual-purpose cookers.

Description

The pressure cooker safety device of uncapping

Technical field

The pressure cooker safety device of uncapping belongs to the electric-heating cooking utensil field of components.Specifically be bayonet type voltage power/common dual-purpose pot with the pressure cooker safety device of uncapping.

Background technology

The present pressure cooker safety device of uncapping typically has two kinds, the one, on pot cover, add a float-controlled valve, utilize the float-controlled valve valve rod move up and down with handgrip on the change of sideboard position realize the security performance of uncapping of pressure cooker; The 2nd, in the pot cover upper handle, be provided with jacking block, screw, putting film, push button, spring and be connected into the transfer bar mechanism of uncapping, lower handle is provided with boss rank bayonet socket position limiting structure, the transfer bar mechanism that must promote when uncapping to uncap action, the venting pressure release reaches safety and uncaps.Safety device has all been realized the security performance of uncapping of pressure cooker though above pressure cooker is uncapped, and exists that used part is various, complex process, the high deficiency of cost.

The utility model content

The technical problems to be solved in the utility model is: design a kind of simple in structure, the pressure cooker of the easy operating safety device of uncapping.

The technical scheme that its technical problem that solves the utility model adopts is: this pressure cooker safety device of uncapping, it is characterized in that: comprise crimping in lock, the pot body, lock sub-ragged edge portion and be provided with convex edge upwards, crimping is hook-shaped in the pot body, insert in the hook of crimping in the pot body convex edge of lock, closes with the fastener of crimping in the pot body to be connected.

The hook of crimping is suitable in the convex edge height of lock and the hook-shaped pot body.

Close when covering, lock moves radially along pot, locks the below that convex edge that sub-ragged edge portion makes progress extend into crimping hook in pot body, and lock falls under the gravity effect of pot cover naturally;

After closing lid, pot inner pressure is equal to or higher than when uncapping the security force value, and pot cover moves up, and locks in the interior crimping hook of sub-convex edge embedding pot body, and hingle can't rotating opening.

When pot inner pressure is lower than when uncapping the security force value, lock falls under the gravity effect of pot cover naturally, and locking son can move radially along pot, uncaps freely;

When uncapping state, lock sub-convex edge and in the interior crimping hook of pot body, throw off.

Compared with prior art, the pressure cooker of the present utility model beneficial effect that safety device had of uncapping is: simple in structure, and to lock sub-ragged edge portion and be provided with convex edge upwards, crimping is hook-shaped in the pot body, insert in the hook of crimping in the pot body convex edge of lock, closes with the fastener of crimping in the pot body to be connected.Profile and usual pressure pot are just the same, clean easily, and be safe and convenient to use.When the pressure cooker internal pressure reaches certain value, manually can't open pot cover to prevent the generation of explosive incident, be suitable for bayonet type voltage power/common dual-purpose pot and use.

The uncap most preferred embodiment of safety device of Fig. 1-the 6th, the utility model pressure cooker.Wherein: 3 pots of bodies of crimping 2 lock in 1 pot of body.

The specific embodiment

Below in conjunction with accompanying drawing 1-6 the utility model pressure cooker safety device of uncapping is described further:

With reference to Fig. 1-3:

Pot body 3 tops are provided with crimping 1 in pot body, lock sub 2 ragged edge portions and are provided with convex edge upwards, and crimping 1 is hook-shaped in the pot body, and insert in the hook of crimping 1 in the pot body convex edge of lock 2, close with the fastener of crimping 1 in the pot body to be connected.Lock 2 ligulate step-like structures for the band handle, the end of handle links to each other with rolling disc, and rolling disc is installed in the pot cover center, and handgrip is installed in the pot cover top and links to each other with the rolling disc at pot cover center, and profile and usual pressure pot are just the same, and be simple in structure, easy operating.Being suitable for bayonet type voltage power/common dual-purpose pot uses.

With reference to Fig. 4:

After closing lid, pot body 3 internal pressures are lower than when uncapping the security force value, and lock 2 falls under the gravity effect of pot cover naturally.

With reference to Fig. 5:

After closing lid, pot body 3 internal pressures are equal to or higher than when uncapping the security force value, and pot cover moves up, and locks in the hook that inserts crimping 1 in the pot body in sub 2 convex edges, and hingle can't rotating opening.

When pot body 3 internal pressures are lower than when uncapping the security force value, lock 2 falls under the gravity effect of pot cover naturally, uncaps freely; With shown in Figure 4.

With reference to Fig. 6:

When uncapping state, throw off in the hook of the convex edge of lock 2 crimping 1 in the pot body.
