Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock mechanism for ensuring the contents of a distribution container such as a marine container or a container loaded on a truck.

[0002]

2. Description of the Related Art As shown in FIGS. 5 and 8, a distribution container 51 has an opening for cargo handling, and a double door 52 is attached to this opening by a hinge 53 so as to be freely opened and closed. It is closed and locked.

In the lock mechanism 50, a lock rod 54 is rotatably mounted on a double door 52 supported by a hinge 53 so as to be openable and closable by a support member (bearing) 55. The lock cam 56 fits into cam holders 57 provided above and below the opening of the container 51.

A handle mounting member 61 is fixed to the lock rod 54, and the handle mounting member 6
A lock handle 63 is attached so as to be rotatable around a support shaft 62 implanted in the lock handle 6.
By rotating the lock cam 56 in the horizontal direction (the direction in which the lock rod rotates), the lock cam 56 is fitted and fixed to the cam holder 57 (FIG. 5).
Is rotated about the support shaft 62, and the door 52
The door 52 is locked when fitted into a latch 64 attached to the front surface of FIG.

[0005] In this state, the lock handle 63 may come off the latch 64 due to the vibration of the vehicle.
If the above procedure is reversed, the door 52 can be easily opened, and there is a possibility that the cargo may be dropped or stolen.

Accordingly, in order to prevent the load loaded on the container 51 from falling and the load from being stolen, the lock handle 6 is used.
3 and the latch 64 are provided with through holes 65 which coincide with each other, and the through holes 65 are locked through the latch 67 of the padlock 66 to secure the cargo. In the above-mentioned means, the latch 67 of the padlock 66 is You can easily break it by cutting it with a clipper.

Therefore, as shown in FIGS. 5 and 7, a first lock member 72 having one end bent in a U-shape and a plurality of through holes 71 provided at regular intervals in a portion extending to the other end, and one end in a U-shape. And a second lock member 76 to which a buckle 75 to which a cylinder lock 74 having a retractable pin plug (not shown) is attached at the other end is fixed, and a through hole 71 of the first lock member 71 is provided. Is secured to the buckle 75 of the second lock member 76, and the U-shaped bent portion 77 of the load securing lock mechanism 70 is attached to the two lock rods 54 near the center of the door 52. (FIG. 5), they are pulled toward each other, and the pin plug of the cylinder lock 74 is inserted into the through hole 71 to lock.

[0008]

However, even with this proposal, there is a problem that if the electric power drill is used to crush the cylinder lock from the front of the cylinder lock, the cylinder lock is easily broken, and it is not possible to guarantee a complete load.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a cargo security lock mechanism which cannot destroy the cylinder lock by an electric drill and can guarantee perfect cargo.

[0010]

According to the present invention, there is provided a first lock member having one end bent into a U-shape and a plurality of through holes provided at regular intervals in a portion extending to the other end; A load consisting of a buckle having one end bent into a U-shape and receiving the portion provided with the through hole of the first lock member at the other end, and a second lock member attached with a cylinder lock having a pin plug capable of moving forward and backward with respect to the through hole. In the guarantee lock mechanism, the keyhole of the cylinder lock is opened on the side bent in the U-shape, and if necessary, a sphere or a cone is arranged at the tip of the axis of the pin plug.

According to the present invention constructed as described above, the keyhole faces the side where the steel strip is bent into a U-shape (door side), so that the cylinder lock cannot be broken by an electric drill, and the pin plug cannot be broken. Since a sphere or a cone is interposed at the tip of the cylinder, the drill of the electric drill idles and slides sideways, so that the drill cannot be rubbed and the cylinder lock cannot be broken.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. In the description, unless otherwise specified, the material used is steel for machine structural use or stainless steel.

In the drawing, a right end of a steel strip is bent into a U-shape, a first lock member 12 having a large number of through holes 11 provided at regular intervals in a center length direction of a portion extending to the other side, and a left end is formed into a U-shape. A buckle 15 having a U-shaped cross section for receiving a portion provided with the through hole 11 of the first lock member 12 is fixedly attached to the other end of the first lock member 12, and the buckle 15 is attached to the through hole 11. A second lock member 16 is fixedly attached to a cylinder lock 14 having a pin plug 13 that can move forward and backward.

The keyhole 18 of the cylinder lock 14 is U-shaped.
Opened on the side bent in the shape of a letter, the key K used is
It is bent between the portion K1 inserted into the cylinder lock 14 and the handle portion K2.

The cargo security lock mechanism 1 as described above
0 hooks the portion 17 bent into a U-shape as shown in FIG. 5 on the lock rod 54, pulls the portion of the first lock member 12 provided with the through hole 11 through the buckle 15,
The second lock members 12 and 16 are sufficiently pulled together to push the pin plug 13 of the cylinder lock 14 to lock.

When unlocking, when the key K is inserted into the keyhole 18 of the cylinder lock 14 facing the door and turned, the pin plug 13 fitted in the through hole 11 of the first lock member 12 is retracted.

As described above, since the keyhole 18 faces the U-shaped bent side of the first and second lock members 12 and 16, that is, the door 52 side, the cylinder lock 14 is broken by an electric drill. Will not be able to.

As shown in FIG. 4, if a sphere 49 or a cone (not shown) is interposed (preferably rotated) at the tip of the pin plug, the drill 48 is set up from the pin plug 13 by an electric drill. Even if it does, it will run idle and warp outward, making it impossible to break the cylinder lock K.

[0019]

As described above, according to the present invention,
The cylinder lock of the load assurance lock mechanism of distribution containers loaded on sea operated containers and trucks can not be broken with an electric drill, and it can be completely protected from the dropping or theft of loads loaded on containers .
