Problems solved by technology

Therefore, with this structure, an extremely strong container fastening force can be exerted, but conversely, since the cone cannot be removed from the corner casting or the socket without manually rotating the cone, the unloading work of the container is troublesome.

[0095] respectively expressed as: figure 1 is a front view of the connector for the container according to the first embodiment of the present invention, figure 2 is a top view, image 3 is the right side view, Figure 4 is the left view, Figure 5 is a plan view. And, respectively expressed as: Figure 6 to Figure 8 is an explanatory diagram of the rotation position of the upper and lower cones, Figure 9 to Figure 12 It is an explanatory diagram of the operating state of the connector. According to its function and structure, this connecting piece is called container fastening twist lock (twist lock). In addition, the description in the "Example" column below also describes the case of loading and unloading a plurality of containers. Therefore, in the case of securing the container to the deck, in the following descriptions, replace "upper container" with "container", and "the lower corner casting of the upper container" with "the lower corner casting of the containe...

[0129] In the above-mentioned first embodiment, the initial position of the shaft 3 is that the rotation engagement structure of the upper cone 4 is at the engagement position, the rotation engagement structure of the lower cone 5 is at the engagement release position, and the second engagement Construct the first rotation stop position capable of action ( Figure 6 ), but not limited thereto, the initial motion position of the shaft 3 can also be the second rotation stop position where the rotation engagement structure of the upper side cone 4 and the rotation engagement structure of the lower side cone 5 are all located at the engagement position, for example .

[0130] From this point of view, in this second embodiment, as Figure 15 As shown, when the initial position of the shaft 3 is that the rotation engagement structure of the upper cone 4 and the rotation engagement structure of the lower cone 5 are both located at the second rotation stop position of the engagement ...

Abstract

The present invention provides a connector for a container, which arranges the cone above and below the shaft, and even if the lower cone is not rotated by manual operation, the lower cone can be cast from the upper corner of the lower container or on the deck. It is possible to improve the workability of unloading by removing the socket, and to ensure the necessary fastening force according to the situation. To achieve this, the lower cone has a rotational engagement structure in which the cone engages with the inner edge of the engagement hole when it is inserted into the upper corner casting or socket and rotated from the disengagement position to the engagement position. In addition, when inserted into the upper corner casting or socket, even if it does not rotate, the protrusion-shaped engaging part provided on one side of the cone will engage with the inner edge of the engaging hole. Two click structure.

Description

technical field [0001] The invention relates to a connecting piece for a container related to container loading fastening technology. The connector of the present invention is used when loading and unloading a plurality of containers, or when fixing containers to the deck of a ship, and the like. Background technique [0002] Conventionally, as disclosed in the following patent document 1, etc., there is known a container connector having an upper cone and a lower cone, wherein the upper cone engages with a lower corner provided on the lower surface of an upper container. Casting (in case of loading multiple containers up and down) or lower corner casting (in case of fixing the container on the deck of the ship) installed on the bottom of the container, and the lower cone is engaged on the upper surface of the lower container The upper corner casting (in the case of loading multiple containers up and down) or the socket installed on the deck of the ship (in the case of fixi...
