Abstract
The invention relates to a pressure pot lock cover structure which comprises a pot body and a pot cover. A plurality of lower pot teeth are annularly arranged on the top of the pot body. Upper pot teeth are arranged at the bottom of the pot cover. The number of the upper pot teeth is the same as that of the lower pot teeth. The two sides of each lower pot tooth are provided with a forward side edge and a reverse side edge respectively, wherein the reverse side edge of at least one lower pot tooth is a blocking edge, and the forward side edges and the other reverse side edges are guiding bevels. A lock pin is transversely arranged inside the pot cover in a sliding mode. The lock pin is located at the portion above the end, corresponding to the lower pot teeth with the blocking edges, of the upper pot teeth. The lock pin points to the center of the pot body. When the pot cover and the pot body are closed, the upper pot teeth are buckled to the bottom of the corresponding lower pot teeth, the lock pin and the blocking edges are blocked, and the outer surface of the pot cover is provided with an unlocking control for controlling the lock pin to get away from the blocking edges. The structure has the advantages that safety and reliability are achieved, the cost is low, operation is convenient, the structure is simple and easy to use, it is ensured that a pressure pot cover cannot be opened violently in the using process of an electric pressure pot, and one-button uncovering can be achieved in a matched mode.
Description
Technical field
The present invention relates to pressure cooker technical field, particularly a kind of lock cover of pressure cooker structure.
Background technology
, it includes pot and pot cover taking current electric pressure cooking saucepan as a example, pot inner top be circular layout have concavo-convex alternate
Pot tooth, the corresponding pot tooth of pot cover inwall is provided with button bit, by rotating pot cover, button bit is in below the pot tooth of protrusion, realizes pot cover
With lid snapping, conversely, button bit in company with pot cover rotate to recessed pot tooth when, pot cover can be dug or open.Due to pot
Uncap when internal gas pressure is higher dangerous property, therefore, existing pressure cooker, all have a set of self-locking mechanism, self-locking mechanism include with
Pot internal gas pressure change and fluctuate air supporting valve, slide laterally the lock pin assembly being arranged in pot cover, lock pin assembly one end
Against the pot tooth surface of pot, the lock pin assembly other end extends at air supporting valve, under normal circumstances, if pot internal gas pressure is relatively low
（Safe opening air pressure）, air supporting valve will not stop lock pin assembly, and during pot cover Unscrew, lock pin assembly is along pot pot tooth surface certainly
By activity, do not affect to uncap；Conversely, when pot internal gas pressure is too high, air supporting valve stops lock pin assembly, so that lock pin assembly can not edge
The freely activity of pot pot tooth surface, therefore pot cover can not rotate, so that can not uncap.Certainly, the above simply theoretical shape
State, but actually still there is certain potential safety hazard in this structure, because certainly existing certain between air supporting valve and lock pin assembly
Diastema（Will be stuck without diastema air supporting valve）Even if, anticyclonic in pot in the case of, if acting on pot cover
Rotation uncap active force larger when, lock pin assembly can overcome the resistance of air supporting valve, and changes the state of air supporting valve, just can be this
Uncap in the state of being unfavorable for uncapping, thus bringing huge potential safety hazard it is therefore desirable to improve to this structure.
Content of the invention
It is an object of the invention to provide a kind of simple and reasonable for structure, safe and reliable, low cost, convenient and simple for operation easily
Lock cover of pressure cooker structure is it is ensured that electric pressure cooking saucepan is unable to violence in use uncaps, but a key can be coordinated to uncap, with gram
Take the deficiencies in the prior art.
The object of the present invention is achieved like this：

On, it is provided with described (the first back-moving spring between button body and pot cover, button body is provided with the push rod for touching connecting rod.
Described button body is vertically movably arranged on pot cover, and connecting rod is driven cooperation with push rod by inclined-plane.
The corresponding push rod of described connecting rod is provided with voussoir, and push rod lower end is provided with pushing and withstanding inclined-plane and voussoir transmission cooperation.
Described pot cover includes enclosing cover and inner cap, and described upper pot tooth is arranged on inner cap inner circumferential；Described lock pin points to pot center
One end be provided with ballhead, the one end at lock pin dorsad pot center is provided with alignment pin, and the corresponding alignment pin of enclosing cover is provided with first through hole,
The corresponding lock pin of inner cap is provided with the second through hole, and alignment pin and lock pin are undertaken in first through hole and in the second through hole respectively.
Second back-moving spring is arranged with described alignment pin, second back-moving spring is crimped between enclosing cover and connecting rod.
As further scheme, described cover top portion is provided with handle, and button body is arranged on handle, in order to user
Operation.
Described pot nside is provided with the cavity that top is opened wide, and is provided with inner shell, inner shell top extends pot top, interior in cavity
Shell top is provided with flanging；Described flanging periphery is concavo-convex alternate, its protuberance be formed as described in cook tooth.
As more specifically another scheme, described alignment pin one end is stretched out outside pot cover through first through hole and is connected with pull handle.When
When lock pin is with stopping side phase gear, by holding pull handle outward, lock pin could be made to leave stop side, now could rotate pot cover.
Beneficial effects of the present invention are as follows：
（1）Such lock cover of pressure cooker structure rotate forward pot cover realize locking closure operation when, due to the guiding of lock pin and tooth of cooking
Contact of incline plane, it is possible to tooth surface shape movement of cooking；After pot cover and pot snapping, the stop side of lock pin and tooth of cooking
Mutually keep off, lock pin can not slide along stopping side, and therefore, pot cover can not reversely rotate unblock, now needs to drive lock by unlock control
Pin exits stop side, you can carries out pot cover and reversely rotates operation, realizes unblock, thus avoiding when pot internal gas pressure is too high, because straight
Connect and firmly rotate pot cover and lead to pot cover to open by mistake the potential safety hazard brought, improve the safety using.
（2）The shape that such lock cover of pressure cooker structure simply slightly changes its tooth of cooking on the basis of existing pressure cooker is come
Realize, its structure is very simple, and cost is extremely low, but greatly improves safe effect.
