Abstract

The utility model provides an open and close cover device of an electric pressure cooker, which is an important part of the electric pressure cooker and ensures the tight locking of the pot coverlid and the cooker. The utility model comprises lid teeth on the coverlid and pot teeth on the pot cover that are connected. The lid teeth are lock catches protruding from the periphery of the external wall of the pot cover and the pot teeth are lockhole grooves on the internal wall of the cooker. Users can observe through the utility model to see whether the lid teeth clamp tightly with the pot teeth, so the use is safe and convenient. The pot teeth are closed lockhole grooves and the lid teeth are protruding lock catches, which need to be inserted in the lockhole grooves to slide in the grooves without falling off and with high tensile resistance. The periphery of the lockhole grooves are an outward rolling structure with high rigidity and firmness. So the locking strength between the pot cover and the cooker is twice than traditional pot teeth and lid teeth structures. Besides, the utility model is safe and reliable and supplies a new variety to the market.

Description

The opening-closing cover device of electric pressure cooking saucepan

Technical field

The utility model relates to a kind of strength member of electric pressure cooking saucepan, and a particularly a kind of pot cover and the pot body of guaranteeing fits and be locked into one, and safe in utilization, the opening-closing cover device of electric pressure cooking saucepan easily.

Background technology

Existing commercially available various types of pots, though its kind, structure is various and different, its open and close cover structure also still is tradition, conventional pot tooth, lid tooth syndeton.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of opening-closing cover device of electric pressure cooking saucepan is provided, and easy to use, safe and reliable, and the tensile strength height, for market increases a kind of selective new fancy variety again.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the opening-closing cover device of electric pressure cooking saucepan connects into integral body by the pot tooth on lid tooth on the pot cover and the pot body and constitutes, described lid tooth is the snap close that protrudes on the pot cover edge outer wall, and described pot tooth is the keyhole slots on the internal wall pot body.

Compared with prior art, advantage of the present utility model is: the opening-closing cover device of this structure, can be directly the pot tooth from the pot body, and observe and cover tooth and whether tipped in pot tooth, so easy to use, relieved.Because of the pot tooth is an enclosed shape keyhole slots structure, the lid tooth is the buckle structure of protrusion again, and snap close must insert in the keyhole slots during use, and can only move in keyhole slots, can not deviate from.And lock buckling groove tensile strength height, its edge is again the flanging structure, intensity height, firmly, so the coupling mechanism force between pot cover, pot body is bigger more than 1 times, safe in utilization, reliable than traditional pot tooth, lid dental structure, for market provides a kind of new designs and varieties.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:

Have uniform on the outer wall at pot cover (5) edge

Shape biconvex snap close is for covering tooth (3), and wherein 5 are biconvex lid tooth (3), and a list is protruding

The female cap tooth is a mark lid tooth (8).

Pot body (1) oral area is a step ladder circular ring shape, and the edge has the cross section to be

The flanging of shape (7) has uniform 6 on the mouth inner wall Shape through hole lock buckling groove is a pot tooth (2), and the through hole at broadside place extends on the upper surface of flanging (7) always, one of them

The shape through hole is slightly little, for mark pot tooth (6) cooperates with mark lid tooth (8).

During use, pot cover (5) is covered on the oral area of pot body (1), and mark lid tooth (8) alignment mark pot tooth (6) is located, make lid tooth (3) biconvex on it play snap close again, insert pot body (1) and go up the wide through hole of pot tooth (9), meanwhile counterclockwise rotate pot cover (5), till the end that makes lid tooth (3) on it always forward the narrow limit of a pot tooth (2) through hole to fastens, pot cover (5) is closed and be locked on pot body (1).

If will open pot cover (5), at this moment need hold handle (4) and press button downwards, clockwise direction rotates pot cover (5) again, when making lid tooth (3) on the pot cover (5) forward a pot body (1) to go up the broadside through hole of pot tooth (9), just can open pot cover (5).

Claims

1. the opening-closing cover device of an electric pressure cooking saucepan, connect into whole formation by the pot tooth on lid tooth on the pot cover (5) and the pot body (1), it is characterized in that the snap close of described lid tooth (3) for protruding on pot cover (5) the edge outer wall, described pot tooth (2) is the keyhole slots on pot body (1) inwall.

2. the opening-closing cover device of electric pressure cooking saucepan according to claim 1 is characterized in that having on the outer wall at pot cover (5) edge uniform
