Description

[Detailed description of the invention] This invention relates to a lock fitting that fits into a lock hole drilled in the corner fitting of the container when lifting the container and locks it to the corner fitting of the container. The device can be easily locked or removed, and an embodiment of this device will be described below based on the drawings.

In FIGS. 1 and 2, 1 is a rotating base, 2 is a movable stopper, 3 is a regulating stopper, and 4 is a locking body, and these four members constitute the lock fitting according to this invention. There is.

As shown in FIG. 3, the rotating base 1 includes an annular engaging head 5 that engages with a lifting hook (not shown) of a lifting device such as a crane, and a cylindrical connecting portion 6 on the lower side. In this connecting portion 6, an internal thread T is threaded.

A pair of lock protrusions 8 are provided protruding from the casing to face each other in the diametrical direction.

The movable stopper 2 is inserted into the connecting portion 6 of the rotating base 1 so that it can rotate freely in the circumferential direction and move in the axial direction, as shown in FIGS. 5 and 6. It has a through hole 9 through which the connecting part 6 of the rotating base 1 is inserted, and has an annular peripheral wall 10 on its outer periphery, and a pair of fan-shaped regulating pieces 11 are arranged in a diametrical direction from the peripheral edge of the peripheral wall 10 and are arranged opposite to each other. Furthermore, a groove 12 into which the lock protrusion 8 can be fitted is formed on the lower surface of the annular peripheral wall 10.

As shown in FIGS. 7 to 9, the regulation stopper 3 has a base 13 in the center, and fan-shaped regulation bodies 14 are formed oppositely on the other side periphery. A regulating protrusion 15 is provided in a protruding manner, and a center hole 16 is provided in the center of the regulating protrusion 15 in a protruding manner.

As shown in FIGS. 10 and 11, the lock body 4 has a solid core frame 18 with a lock head 17 formed at one end.

The lock head 17 has the relationship W<L and is formed to have a size substantially equal to W' and L' of the regulating protrusion 15, and an outer screw 19 is screwed into the upper part of the core frame 18. has been done.

In the figure, 20 indicates a part of the container, and 21 is a corner fitting in which a through hole 22 and a large diameter blind through hole 23 communicating with the through hole 22 are bored.

The assembly of the four members L2, 3, and 4 mentioned above will be described.

First, the lock protrusion 8 is removed, and the connecting portion 6 of the rotating base 1 is inserted into the through hole 9 of the movable stopper 2Q.
Reinstall.

Next, the core frame 18 of the lock body 4 is inserted into the center hole 16 of the regulation stopper 3 from the regulation protrusion 15 side, and the externally diagonal screw 1 of the core frame 18 is inserted.
9 portion protrudes upward from the base 13, and in this state, the externally diagonal screw 19 portion is screwed into the inner screw 7 screwed into the connecting portion 6 of the rotating base 1, and the lock body is attached to the rotating base 1. 4 are connected so that they can rotate simultaneously.

At this time, in order to make the above-mentioned connected state more appropriate, a lock pin (not shown) may be inserted through the connecting portion 6 and the core frame 18 in the diametrical direction.

With this, the assembly of the four members described above is completed.

The operation and effects of this device configured as described above will be described.

First, as shown in FIG. 11, the lock head 17 of the lock body 4 and the regulating protrusion 15 of the regulating stopper 3 are inserted into the through hole 22 of the corner fitting 21, and the lock head 17 is inserted into the large diameter blind through hole 23. Make it exist within.

Therefore, the through hole 22 has a width and length that are slightly thicker than the widths w, w' and lengths L, L' of the regulating protrusion 15 and the lock head 17.

Next, the engaging head 5 of the rotating base 1 is grasped and the rotating base 1 is rotated by at least 90 parts in the circumferential direction.

Following this rotation, the lock body 4 also rotates, so that the lock head 17 is displaced within the blind through hole 23 and locked so that it cannot be removed from the through hole 22, as shown in FIG.

Furthermore, by rotating the movable stopper 2 in the circumferential direction, the regulating piece 1
The movable stopper 2 is moved in the axial direction of the connecting portion 6 by placing the regulating piece 11 between the pair of regulating bodies 14 in the circumferential direction. The movable stopper 2 is placed on the base 13 of the regulation stopper 3, and the lock protrusion 8 is inserted into the groove 12 to lock it.

Since the rotating body 1 cannot be rotated due to the above-mentioned lock, the lock head 17 is not pulled out from the through hole 22, so that a completely locked state is obtained and the container 20 can be suspended.

To release the lock and remove the hanging bracket from the corner fitting 21, move the movable stopper 2 upward, release the engagement between the groove 12 and the lock protrusion 8, and rotate it further in the circumferential direction to move the regulating piece 11 to the regulating body 14. If placed on top, the rotating base 1 can be rotated, and by returning the lock head 17 to its original state, it can be pulled out from the through hole 22 and removed.

As described above, this invention has the advantage of being able to provide a hanging fixture that is easy to lock and unlock.
