Fixing and connecting mechanism for two side box plates of a foldable pull rod containing box

Abstract

The fixed connection mechanism of the two side panels of the folding trolley storage box, the storage box body composed of the front box panel, the two side box panels, the rear box panel and the movable bottom panel. Including side box panel A and side box panel B, a connection mechanism is set between side box panel A and side box panel B, and the connection mechanism includes the middle joint of side box panel A and side box panel B respectively Set the hanging edges, side linings and connecting ears at intervals, the hanging edges and side linings on the side box plate of block A overlap with the side linings and hanging edges on the side box plate of block B inside and outside, and the pins pass through the pins connecting the ears The hole connects the two sides of the box plate, and the frame of the two side box plates is respectively made with a clamping groove, and the limit step is set on the frame of the second side box plate to correspond to the position of the clamping groove. There are clamping grooves and clamping ribs, the clamping grooves of the clamping parts are clamped outside the upper frame, and the clamping ribs cooperate with the clamping grooves. When the clamping parts are located at the joints of the two side box panels, the two side box panels are connected and fixed.

Description

technical field [0001] The invention relates to a storage box, in particular to a fixed connection mechanism for box panels on both sides of a foldable trolley storage box. Background technique [0002] The storage box is used to facilitate people to arrange objects. The traditional storage box is generally integral and cannot be folded, so it is large in size. When storing and transporting, it takes up a lot of space and increases storage and transportation costs. Therefore, people invented the folding storage box. , the existing folding storage box includes a front box board, a rear box board, two side boards and a movable bottom board. Usually, the two side boards are divided into two pieces respectively, and the two side boards are connected by pins. When folding , lift one side of the movable bottom plate upwards, and then fold the two side box panels through pins, the volume of the folded storage box is reduced, reducing storage and transportation costs, but the two si...

[0002] The storage box is used to facilitate people to arrange objects. The traditional storage box is generally integral and cannot be folded, so it is large in size. When storing and transporting, it takes up a lot of space and increases storage and transportation costs. Therefore, people invented the folding storage box. , the existing folding storage box includes a front box board, a rear box board, two side boards and a movable bottom board. Usually, the two side boards are divided into two pieces respectively, and the two side boards are connected by pins. When folding , lift one side of the movable bottom plate upwards, and then fold the two side box panels through pins, the volume of the folded storage box is reduced, reducing storage and transportation costs, but the two side box panels are only connected by pins , in the open state, under the influence of external force, there is no fixing mechanism for the two side box panels connected by pins, which makes the two side box panels easy to fold, poor stability, and inconvenient to use
