Each of the locking portions 1c at both ends is bifurcated at the tip with respect to the side surface, and a circular locking hole 1e is provided at each of the branch portions. Two seals 7 are provided at a joint portion which is joined to the main body 3 at a position a predetermined distance from the center of both the locking holes 1e, that is, in a state where the main body 3 is inserted.
However, each is wound around the locking rod 1 in a belt shape.
The inner surfaces of the two seals 7 are tapered so as to be in close contact with the two joining ports 3d of the main body described later.

The main body 3 has a cylindrical shape as shown in FIGS. 1 to 3 and 5, and includes a metal cylindrical shaft portion 3a and a lock mechanism 3b inside the shaft portion. The periphery of the shaft center 3a is covered with a cover 3c made of a soft synthetic resin. Also, two joining ports 3d into which the locking rod 1 is inserted and joined are provided at predetermined intervals vertically in the longitudinal direction, and these are provided in the locking rod 1 to be inserted. The periphery of the mouth rises in a tapered shape so as to be in close contact with the two seals 7 provided.

The lock mechanism 3b has a central hole 3f, a bar 3g,
And an unlocking operation unit 3h. Central hole 3f
Is formed in a shape smaller in diameter than both the joint ports 3d, orthogonal to the both joint ports 3d, and penetrating both the joint ports 3d. A rod 3g having a rectangular cross section is swingably inserted into the center hole 3f, and one end of the rod 3g is inserted into the rod 3g.
Is linked to an unlocking operation unit 3h that swings the. The bar 3g is inserted into the locking holes 1e of the both locking portions 1c inserted from the two joint ports 3d. The unlock operation section 3h has a key
9 is provided with a keyhole 3i in which the keyhole 9 is inserted.

An unlocking operation section 3h is provided at one end of the main body 3.
A sealing cap 11 for sealing is provided detachably. FIG. 5 shows a state when the sealing cap 11 is mounted, and FIG. 6 shows a right side view when the sealing cap 11 is detached. The sealing cap 11 is fitted into the cover 3c around the unlocking operation section 3h without any gap at the time of unlocking or other than locking, and seals the unlocking operation section 3h. The ring 13 has substantially the same diameter as the main body 3 and is fitted so as not to fall out into a groove provided in the main body 3. The sealing cap 11 is fitted to the ring 13 via a connecting hand 15. By doing so, it will not be lost from the main body 3 when it is detached.

The locking operation is performed as follows. First, 2
One locking part 1 at each end of the two locking rods 1

And irreversible.

Next or simultaneously, another main body 3 is attached to the other locking portion 1c of the two locking rods 1 respectively.
And the same operation as above is performed.
That is, in a state in which the seal 7 is in close contact with both the joint ports 3d, the key 9 is inserted into the keyhole 3i of the unlocking operation section 3h and rotated, so that the unlocking operation section 3h is moved from the position shown in FIG.
Is rotated by 90 ° (that is, rotated in the locking direction) to lock both locking portions 1c, and the locking rod 1
The main body 3 and the main body 3 are inseparable and cannot be separated. Here, the junction between the locking rod 1 and the main body 3 is well sealed regardless of the molding precision because the tapered surfaces having the slope are in close contact with each other.

The unlocking operation is performed in the reverse of this operation. That is, by inserting the key 9 into the keyhole 3i of each main body 3 and rotating it 90 ° in the unlocking direction, that is, in the direction opposite to the locking direction, the bar 3g is moved to the position shown in FIG. The bar 3g may be released from the portion 1c to release the lock, and the lock rod 1 may be withdrawn from the main body 3.

When the locking rod 1 is released from the main body 3 at the time of unlocking, as shown in FIGS. 4 and 5, four linear locking rods 1 and the linear main body 3 are provided. Respectively, and the bulk can be reduced. This makes it possible to considerably reduce the size of the large and bulky locking device, which is convenient for storing and carrying.

Moreover, since it is composed of the hard rod-shaped locking rod 1 and the main body 3, the strength is not impaired as compared with a normal locking rod. In addition, since it does not include a U-shaped deformed portion, it can be made of an extremely hard material, and there is no deformed portion (U-shaped portion) where stress concentrates, so that the strength can be extremely increased. Since the connecting portion between the main body 3 and the locking rod 1 is also locked by a strong locking mechanism, the locking device for preventing theft has high strength.

Further, since the locking rod 1 is straight and does not include a curved portion, no extreme deformation of the bar is required.
Manufacturing has become simple. Therefore, the manufacturing cost is also reduced. Furthermore, since there are two main bodies 3 having a locking mechanism, that is, since there are two unlocking operation units 3h,
It can be removed from either the upper left or lower right direction of the loop, and the unlocking operation is convenient even in a narrow place or near a wall.

In the above embodiment , the locking rod 1 is
Although the Jo may be a bulged locking rod 1 somewhat curved in a range capable of maintaining the ease of manufacturing.
