Description
Technical field
The utility model relates to electric pressure cooking saucepan, particularly a kind of electric pressure cooking saucepan pot cover.
Background technology
Common electric pressure cooking saucepan, when user's neglected loading sealing ring or interior pot, still can pass through handle twist-lock ring, pot cover is in the lock state, but, the sealing ring of but can not having pointed out user's neglected loading in this case or do not put interior pot, thus the phenomenon of gas leakage in electric pressure cooking saucepan generation abnormal work or the work caused.
In order to address the above problem, CN200966553 discloses a kind of cooker lid locking device of electric pressure cooking saucepan, comprise inner pot cover, locking ring and outer pot cover, outer pot covers and is provided with the connecting rod that links to each other with handle, connecting rod one end links to each other with leg on the locking ring, locking ring is provided with stop pin, and corresponding is first lock hole and second lock hole that is separately positioned on locking ring and the inner pot cover therewith, and the stop pin bottom is inserted in first lock hole and second lock hole; The first lock hole side is provided with the limited step that projects upwards, and limited step is provided with recess, and the stop pin middle part is provided with boss.In order better to realize the pot cover locking, first lock hole is an arc slot, and the rotational angle the when length of first lock hole and pot cover locking adapts.This utility model make neglected loading sealing ring or leakage put in pot can stop locking ring to rotate, with prompting user's neglected loading sealing ring or do not put interior pot, and stop pot cover and pot body to fasten locking.
But because stop pin is loosening fully, then there is potential safety hazard in the hole if stop pin goes out of lock, can not reach the purpose of safety locking in this latch-up structure.In addition, because stop pin is loosening fully, thereby when uncapping, stop pin is contracted in pot cover, and gravity can not make its reset locking this moment, thereby still can rotate pot cover after uncapping, cause and use inconvenience owing to inertia.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of simple and reasonable, cost of manufacture is low, safety coefficient is high, easy to assembly electric pressure cooking saucepan pot cover, can stop during pot in neglected loading sealing ring or leakage are put and close lid.
The technical scheme in the invention for solving the above technical problem is as follows:
A kind of electric pressure cooking saucepan pot cover comprises internal head cover and interior buckle closure; It is characterized in that: also comprise lock pin, the middle part of lock pin is provided with export-oriented salient point, the top of interior buckle closure is provided with arc-shaped slide rail, one end of arc-shaped slide rail also is provided with the recess that matches with the salient point of lock pin, the salient point of lock pin is with back-moving spring toward top, and the top of back-moving spring is provided with pressing plate, and pressing plate is fixed on the internal head cover, pressing plate is provided with first pin-and-hole that matches with the upper end of lock pin, and internal head cover is provided with second pin-and-hole that matches with the lower end of lock pin.
Further, the rotational angle of the length of described arc-shaped slide rail and interior buckle closure adapts.
Further, internal head cover is provided with projection, and the centre of projection is provided with screw, with screw pressing plate is fixed on the projection.
Further, also be provided with locating hole on the pressing plate, internal head cover is provided with and the corresponding reference column of locating hole.
Further, arc-shaped slide rail is an arcuate socket.
Further, arc-shaped slide rail is the arc notch of the top edge of buckle closure in being located at.
Further, the salient point of lock pin be circular toward the cross section on top, and the cross section of the past lower part of the salient point of lock pin is square, triangle or D shape.
Further, the salient point of lock pin is square, triangle or D shape toward the cross section on top, and the salient point of lock pin is circular, square, triangle or D shape toward the cross section of lower part.Two-part cross section about the lock pin is if be all circle, and then lock pin itself may rotate, and this will be unfavorable for the locking of lock pin.Therefore, the two-part cross section up and down of lock pin should not be all circle, and one of them is set to non-circular can avoiding and rotates.
During buckle closure, the lower end of lock pin can not hinder interior buckle closure in the purpose that the utility model is provided with arc-shaped slide rail was to rotate.Lock pin can move up and down under the qualification of first pin-and-hole and second pin-and-hole, when uncapping, and the recess that the salient point of lock pin links to each other with arc-shaped slide rail on the interior buckle closure, because the effect of back-moving spring, salient point will be stuck on the recess, the rotation of buckle closure in the restriction; When normal placement sealing ring and interior pot close when cover, sealing ring is with lock pin jack-up, and salient point will break away from recess, but normal occlusion covers; When sealing ring or interior pot are put in leakage, can not close lid.
The utility model adopts back-moving spring to match with lock pin, pressing plate, can not rotate pot cover after can guaranteeing to uncap, and more convenient to use, reliable, locking effect is better, and is safer.
Description of drawings
Fig. 1 is the schematic diagram of the utility model illustrative examples.
Fig. 2 is the pot cover schematic diagram that assembles lock pin.
Generalized section when Fig. 3 is lock pin locking pot cover.
