Description

Lock components for folding cabinets

technical field

The utility model relates to a lock assembly of a folding cabinet. The lock assembly is applied to a foldable container, which can lock the folding cabinet after the container is folded and folded without loading goods, so as to facilitate transportation and storage.

Background technique

Generally, the traditional container adopts a fixed structure and has a considerable standardized space to load a large amount of cargo. The type of container commonly used in general cargo transportation is a dry container (dry container), and its specifications mainly include 20-foot containers (outer dimensions About 20 feet in length x 8 feet in width x 8 feet 6 inches in height, that is, about 6.058 meters in length x 2.438 meters in width x 2.591 meters in height), 40 feet container (that is, the length is 12.192 meters, and the other dimensions are the same as those of 20 The same size cabinet), etc. Only when the container is unloaded and unused, it is often stored in the container storage yard or general space, and the huge volume of the empty container causes a great waste of storage, and when storing the container, it is often necessary to stack the container with a spreader , to achieve space utilization; because the height of each container is 2.591 meters, the stacking height of several layers of containers is considerable, so that stacking is very troublesome and potentially dangerous. In addition, empty containers are being transferred 1. When moving, limited by the fixed volume of the empty container, the benefit of transporting it by a specific transportation method (such as a container-connected vehicle) is low, and only a certain number of empty containers can be transported to a limited extent, resulting in huge transportation costs.

A kind of collapsible container adopted by people in the transport industry at present, as the disclosed collapsible container of CN2761544Y, has just solved the above technical problems. The structure of this collapsible container includes a chassis, a top plate relative to the chassis, Two opposite side plates, a front end plate and a rear end plate relative to the front end plate form a rectangular body together; it is characterized in that: the front end plate and the rear end plate are pivotally connected to a front end and a rear end of the chassis respectively At the rear end, each side panel has an upper side panel and a lower side panel, wherein an upper end of the upper side panel is pivotally connected to one side of the top panel, and a lower end of the lower side panel is pivotally connected to the chassis One side of the upper side panel is pivotally connected to an upper end of the lower side panel; The end plates do not pivot with the chassis and prevent the upper and lower side plates from pivoting relative to each other. And make the formed rectangular body have sufficient rigidity and strength.

The steps of folding the container are to hook the front panel and the rear panel with the spreader frame, and the operator respectively opens the fixing components of the front panel and the rear panel, and slowly lets the front panel and the rear panel dump on the inner chassis of the container; The top frame is hung by the spreader, and the operator opens the fixed components inside the container so that the frame of the container can be folded slowly. Use the fixed locks to fix the container corners at the four corners of the upper frame and the lower frame, so that the container is fixed in the folded state, which is convenient for handling and storage. Another kind of lockset that is arranged between the container corners of the upper and lower containers between the upper and lower containers in the folded state will lock the upper and lower containers to facilitate stacking. The folded container occupies about 20% of the original height after being folded, so a considerable volume can be saved.

But because the fixed lockset of above-mentioned foldable container is when fixing the container angle of four corners of upper frame and lower frame, fixed lockset is the outside of the container corner of upper frame and lower frame four corners, and the fixed lockset part exceeds container corner like this, causes the whole container The size exceeds the standard, which is absolutely not allowed in the container transportation industry, and will cause a lot of trouble during transportation.

The inventor invented a joint assembly of a folding cabinet on April 27, 2006, which includes a body, at least one rotating shaft arranged on the body; at least one joint is arranged on the rotating shaft; The fixed block is installed between the joint and the main body, and the fixed block can make the joint and the main body extend and locate.
