Handle linkage switch of heat preservation dinner flask

Abstract

The invention discloses a handle linkage switch of a heat preservation dinner flask, which comprises a flask body and a flask cover of the dinner flask and is characterized in that switch insert boards are arranged at two sides of the flask cover; handles are arranged at two sides of the flask and provided with linkage switches; each linkage switch comprises a lower handle shell, an upper handle shell, and a switch clamp body arranged between the upper handle shell and the lower handle shell; the switch clamp body comprises a U-shaped splint and a grip, and the U-shaped splint and two ends ofthe grip are connected by respective arc-shaped elastic plate; the lower handle shell comprises a main rod in contact with the flask body, and a lower shell integrally connected with the main rod; the main rod is provided with a splint groove and a splint opening; the lower shell is internally provided with a grip groove and a grip opening; the grip groove is matched with the grip; the splint groove is matched with a U-shaped splint guiding plate; the splint opening is matched with the U-shaped splint guiding plate; the inner wall of a clamping piece and the upper surface of the splint opening are matched with the insert board of the flask cover up and down; the upper handle shell is internally provided with a grip cavity and a grip hole; and the grip cavity is matched wit the upper part of the grip.

Description

technical field [0001] The invention relates to a thermal insulation rice bucket, in particular to a handle linkage switch of a thermal insulation rice bucket, and belongs to the field of kitchen utensils. Background technique [0002] The heat preservation rice bucket is mainly composed of a bucket body and a bucket lid. In order to make the rice bucket have good thermal insulation, the bucket body and the bucket lid are in contact with each other to achieve sealing, and at the same time it is convenient to move, so there is usually a matching connection mechanism between the bucket body and the bucket lid. . The existing commonly used connection mechanism is generally that the barrel body and the barrel cover are connected by a screw, but the screw connection is only suitable for a round rice bucket, and the operation is troublesome; the other is a knob switch, and an ingot screw is installed on the side of the barrel. There is a long slot on the edge of the lid. When the...

AI Technical Summary

Problems solved by technology

The existing commonly used connection mechanism is generally that the barrel body and the barrel cover are connected by a screw, but the screw connection is only suitable for a round rice bucket, and the operation is troublesome; the other is a knob switch, and an ingot screw is installed on the side of the barrel. There is a long slot on the edge of the lid. When the ingot turns to be parallel to the long slot, the lid can be taken out. When the ingot turns to a position perpendicular to the long slot, the lid is locked and cannot be opened.

The disadvantage of using ingot screws is that it is relatively large in size, and it is easy to collide with hands or other objects when it is higher than the lid.

Therefore, people have designed various connecting mechanisms between the staving and the bung, such as Chinese patent 200820121342.9, titled "connection mechanism between the staving and bung of the thermal insulation rice bucket", and this technical scheme relates to the connection of the staving and the inner tank of the staving. The connecting piece and the fixed splint cooperate with the protrusion of the barrel lid. The fixed splint includes the upper, lower and side brackets, as well as the ribs. The geometry is complex and the processing is difficult, especially when it involves parts such as the barrel inner tank, which is troublesome to assemble
