Locking mechanism and telescopic container

Abstract

The invention provides a sleeve type container that aims to save labor of assembly operations and bundling operations of the sleeve type container and to reliably improve a locking mechanism for the sleeve type container and that is provided with the locking mechanism, wherein the locking mechanism for the sleeve type container comprises a clamp portion set at an end of a sleeve, and a locking component that is set on a tray and the that is capable of clamping on the clamp portion to prohibit the tray from popping out from a locking position where the sleeve is separated from to the clamp portion but allows the tray to slide between the locking relieving positions where the sleeve is separated from; with the locking mechanism for the sleeve type container, a locking component is projected from the outer surface of the outer side wall of the tray at the locking relieving position; and at the locking position, the locking component and the outer surface of the outer side wall of the tray are located at the same surface or the locking component is restrained in the inner side.

Description

technical field [0001] The present invention relates to a locking mechanism used in a telescopic container (foldable container) in which an opening end of a cylindrical sleeve is closed by a pallet, and a telescopic container including the locking mechanism. Background technique [0002] Conventionally, there is known a locking mechanism capable of obtaining a locked state in which an up-and-down pallet is prohibited from being disengaged from a sleeve of a sleeve-type container and an unlocked state in which an up-and-down pallet is allowed to disengage from a sleeve (for example, refer to the following patent document 1 or 2). [0003] The locking mechanism is provided with: a through hole provided at the upper and lower ends of the sleeve; This is able to move the protruding piece. [0004] However, when the operation part is provided on the upper surface side and / or the lower surface side of the tray, there is a problem that the operation of the lock mechanism becomes ...

AI Technical Summary

Problems solved by technology

This kind of work is very complicated for the workers who wear many gloves at the packing work site because it needs to rely on the feeling of the fingertips.

In addition, in the conventional locking mechanism, it is not easy to visually recognize whether the lower tray is locked or not.

[0006] Furthermore, similarly to the case where the operation part is provided on the upper surface side of the upper tray, in the case of stacking in the state of storing goods, it is not easy to confirm whether it is in the locked state from the side.

In addition, the upper tray is different from the lower tray. If there is no article placed on the upper side, although it can be confirmed from the upper surface whether it is in the locked state, but when there is a tray etc. placed on the upper side of the upper tray, It is also difficult to confirm from the upper surface side

[0007] In addition, according to the invention described in the following patent document 2, a long hole for slidably attaching the sliding operation part is opened, and the long hole connects the inside and outside of the pallet with a hollow structure and the inside of the telescopic container. The space communicates with the outside (for example, referring to Patent Document 2 Figure 8 etc.), so rainwater enters the interior of the pallet and the interior of the sleeve container from the outside through the long hole, and there are still problems in waterproof performance
