Lid connection structure

Abstract

The invention discloses a cover connecting structure which comprises an upper cover and a lower cover. A connecting piece is arranged on the side face of the upper cover. A lower clamping groove is formed in the lower end face of the connecting piece. The left side edge and the right side edge of the lower end face of the connecting piece extend upwards to form two elastic positioning claws. The tail ends of the two elastic positioning claws extend outwards to form clamping buckles. A connecting piece groove is formed in the lower cover. Side windows are formed in the left side and the right side of the connecting piece groove, and side clamping grooves are formed in the portions, located above the side windows, of the inner wall of the connecting piece groove. An opening-closing piece is arranged at the bottom of the connecting piece groove. A lower clamping point is arranged on the upper end face of the opening-closing piece. The left side and the right side of the opening-closing piece extend upwards along the side wall of the connecting piece groove, and after the tail ends extend outwards, the left side and the right side of the opening-closing piece are clamped into the side windows of the connecting piece groove. According to the cover connecting structure, the connecting piece is arranged between the upper cover and the lower cover, the upper cover can be rotationally connected with the lower cover so that flipping and opening can be achieved, the connecting piece can be pulled out of the connecting piece groove in the lower cover so that separation of the upper cover and the lower cover can be achieved, normal application is facilitated, and the upper cover can be detached for independent cleaning or contents can be placed or fetched conveniently.

Description

technical field [0001] The invention relates to a cover connection structure. Background technique [0002] Usually, the container needs to be equipped with a cover to prevent the leakage of the contents in the container, or to seal or insulate the contents of the container accordingly, such as the thermal insulation rice bucket, thermal insulation lunch box and thermos cup etc. commonly used in the family. However, there are two connection methods for the lid on the current heat-insulating rice bucket or heat-insulating lunch box: the first lid is fixedly connected to the container, and the lid generally cannot be removed, that is, it cannot be disassembled, so the container and the lid need to be cleaned together when cleaning, and The connection between the lid and the container is often difficult to clean the dirt at the connection structure due to its complex structure, causing bacteria to grow and affecting hygiene and health. At the same time, the lid cannot be remove...

Problems solved by technology

However, there are two connection methods for the lid on the current heat-insulating rice bucket or heat-insulating lunch box: the first lid is fixedly connected to the container, and the lid generally cannot be removed, that is, it cannot be disassembled, so the container and the lid need to be cleaned together when cleaning, and The connection between the lid and the container is often difficult to clean the dirt at the connection structure due to its complex structure, causing bacteria to grow and affecting hygiene and health. At the same time, the lid cannot be removed. Picking and placing of items; the second type of lid is not connected to the container, that is, the lid and the container are separated. In this way, although it is easy to clean, it is easy to lose the lid when it is removed
