Problems solved by technology

Because the twist lock device does not have an automatic flip function, this flip needs manual operation. Sometimes, due to human judgment errors, when the living hinge is erected, it is forgotten to first turn the twist lock device into the twist lock box. It will cause extrusion or even damage to the twist-lock device, which will affect the use of the twist-lock device

Abstract

The invention discloses a folding case comprising a base frame, end frame arranged at the two ends of the base frame and a hinge device. The hinge device comprises a fixed hinge and a movable hinge. The folding case further comprises a twist lock device comprising a coupling twist lock and a twist lock arm. One end of the twist lock arm is fixedly connected with the coupling twist lock. The other end of the twist lock arm is connected with the base frame in a pivoted mode. The guiding faces / guiding face are / is arranged in the corresponding positions / position of the twist lock arm and / or the moveable hinge. During the period that the end frames are pivoted from folding positions to vertical positions, the guiding face arranged on one of the twist lock arm and the movable hinge makes contact with the other guiding face arranged on one of the twist lock arm and the movable hinge, so that the twist lock device is pivoted from a coupling position to a storage position along with pivoting of the movable hinge from the folding position to the vertical position; and accordingly the movable hinge can apply acting force to the twist lock arm through the guiding face in the pivoting period, and the twist lock arm is made to be pivoted to the storage position without the need for manual turnover of the twist lock device.

Description

technical field [0001] The invention relates to the field of containers, in particular to a folding box. Background technique [0002] The four top corners of the fixed hinge of the folding box are equipped with twist lock devices, which function in that the twist lock device acts as a connecting mechanism to connect two folding boxes during folding and stacking transportation. [0003] Such as figure 1 As shown, the existing twist lock device 1 includes a twist lock 11 and a twist lock arm 12. The existing twist lock arm 12 includes a twist lock arm arc surface 121. The twist lock device 1 connects the twist lock arm shaft 122 with the folding box connect. [0004] When the movable hinge is in the folded state and the folding box is in the hanging state, the twist lock device is turned over to the L-shaped corner fitting of the fixed hinge, and connects the top hole of the L-shaped corner fitting with the bottom corner fitting of another folding box. holes for connection...
