Safe locking device of pressure incubation electric rice boiler

Abstract

The invention relates to a safety locking mechanism of a pressure heat preservation electric cooker, comprising a hook arranged on a locking ring and a flange arranged on the cooker body. The hook can be hooked on the flange, an inner cover is closely pressed between the locking ring and the cooker body; an outer cover is arranged above the inner cover and the center of the inner cover is provided with a locating pole which is provided with a pin; one end of a connecting plate is pivoted on the locating pole and the other end is slidingly connected with the pin; the switch handle is fixed on the connecting plate which is provided with induction accessories; the outer cover, the locking ring or the inner cover is correspondingly provided with a sensor. When the striking switch handle is turned on or the electric cooker is turned off, the switch handle drives the connecting plate revolve around the handle; the connecting plate revolves around the locating pole of the inner cover; the pin which is connected with a stripped open chute on the connecting plate slides inside the stripped open chute while revolving at the same time to drive the locking ring and the flange of the cooker body to be separated or occluded. Induction accessories and sensors are arranged; therefore the locking state of the outer cover can be correctly inducted. The safety locking mechanism has the advantages of simple and reasonable structure, easy and labor-saving operation and large safety degree.

Description

technical field [0001] The invention relates to a pressure heat preservation electric cooker, in particular to a safety locking mechanism of a pressure heat preservation electric rice cooker. Background technique [0002] attached figure 1 - attached figure 2 Shown is an embodiment of the prior art. When the switch handle 6' on the electric pressure cooker is held to open or close, the locking ring 1' will rotate accordingly under the action of the rotating connecting rod 5', and the locking ring will rotate on the inner cover. 2' will contact and generate friction with the guide protrusion 2.2' arranged on the inner cover when rotating, friction noise will be generated during the rotation process, and it will be more laborious. Some manufacturers remove the guide protrusion 2.2' on the inner cover in order to eliminate friction. But after removing the guide protrusion, the locking ring 1 'can appear to swim left and right, and its consequence is: the clasp 1.1 ' on the ...
