The insertion portion 23 is open to the outer side in the axial direction of the bearing portion 14 (above the first and second figures), and the pocket portion 25 is opposite to the inner side in the axial direction of the bearing 14 (the lower side of the first and second figures). open.

As shown in FIG. 3, the bearing portion 14 is provided with a groove-shaped cutout portion 26 throughout the insertion portion 23, the step portion 24, and the pocket portion 25. The insertion portion 23 has a semicircular planar shape, and the notch portion 26 having the same width as the diameter of the insertion portion 23 is continuously provided to the insertion portion 23. The diameter of the insertion portion 23 and the width of the cutout portion 26 equal to the diameter are the straightness of the tie rod 15 The diameter is equal, or the amount of the fitting gap is considered to be large.

The pocket portion 25 is formed to have a larger diameter than the insertion portion 23 by an amount corresponding to the width of the step portion 24. Since the width of the slit portion 26 is formed to be smaller than the diameter of the pocket portion 25, the projection 16 fitted into the pocket portion 25 is prevented from coming out of the slit portion 26 in the radial direction outer side.

As shown in FIG. 3, a mounting member 27 is fixed to the outer surface of the bearing portion 14 on the side opposite to the radial direction of the cutout portion 26, and a locking claw 17 is provided to the mounting member 27.

The locking claws 17 are disposed on the inner side surface of the mounting member 27, and are mounted to be able to face the bearing portion 14 by inserting the support pins 31 fixed to both side portions of the mounting member 27 at a position lower than the bearing portion 14. Shake in the direction. The length of the lock claw 17 is such that the lower end portion thereof is exposed below the attachment member 27, and the exposed portion is an operation portion that is operated from the outside. The upper end portion of the locking claw 17 is formed to reach the length of the inside of the pocket portion 25.

The locking claws 17 are constantly pushed in the radial direction in the radial direction by the coil springs (not shown) inserted through the support pins 31, and are engaged with the lower end portions of the projections 16 of the tie rods 15. Thereby, the tie rod 15 is locked. Further, by pushing the lower end portion of the lock pawl 17 toward the inner side, the lock pawl 17 is disengaged from the projection 16 of the tie rod 15 against the elasticity of the coil spring, and the lock is released.

As shown in Figs. 1 and 2, the tie rod 15 is provided with a projection 16 at a plurality of locations at a predetermined pitch at a lower end portion (an end portion that is inserted into the side of the elastic buckle main body 11). The protrusion 16 is an inverted conical trapezoid, and the diameter of the lower end of the protrusion 16 is formed to be slightly larger than that of the tie rod 15 The diameter is a portion that is in contact with the locking claws 17. The upper end portion of the projection 16 is formed to have a larger diameter than the tie rod 15 and is engaged with the step portion 24 of the pocket portion 25.

The tie rod 15 is prevented from coming out of the elastic buckle main body 11 in the axial direction outward by engaging the upper end portion of the projection 16 with the step portion 24 of the pocket portion 25. Although it is freely movable in the axial direction in the state after the lock is released, the movement of the lock claw 17 in the locked state of the projection 16 is prevented from moving in the axial direction.

As described above, the width of the notch portion 26 of the bearing portion 14 is equal to or slightly larger than the diameter of the tie rod 15, and is narrower than the maximum diameter portion of the projection 16, so that even in the above-described locked state, there is a diameter The external force that has come out in the direction acts on the tie bar 15, and the protrusion 16 does not come out because it is engaged with the inner wall surface of the pocket portion 25. Further, even if the tie bar 15 is inclined in the gap between the pocket portion 25 and the projection 16, the locking claw 17 restricts the movement of the projection 16 to prevent the inclination thereof from exceeding a certain level or more.

At the upper end portion of the tie bar 15 (the end portion farther from the elastic turnbuckle body 11), the hook portion 37 is slidably attached by the pin 38. Since the center of gravity of the hook portion 37 is deviated from the center of the tie rod 15, it is in a state of being tilted with respect to the tie rod 15 in a natural state. This is a consideration of the convenience of the work when the tie rod 15 is engaged with the corner fixture of the container 7.

When the tie rod 15 is used as an original adjustment function member and the front end is connected to a lashing bar, the tie rod 15 can be shorter than the case shown in the figure, or can be engaged. The hook is also secured Installed as a stand-up state.

Usually, the sleeve bolt shaft 13 is screwed to the bearing portion 12 which is one of the elastic screw body 11 and the tie rod 15 is in a state of being separated from the elastic screw body 11. When the pulling system is stacked in the container of the ship, the connecting pin 21 of the connecting portion 19 of the sleeve bolt shaft 13 is coupled to the draw bridge on the deck or the eye panel 5 provided on the pull stay 61. The hook portion 37 of the tie rod 15 is engaged with the corner fixture 71 at the upper portion of the container, and the tie rod 15 is fitted to the bearing portion 14 at the upper end of the elastic buckle body 11 from the slit portion 26 in the radial direction.

At this time, when the protrusion 16 is located at the position of the notch portion 26, the elastic screw body 11 is rotated, the position of the protrusion 16 is separated from the notch portion 26, and the rod portion between the protrusions 16 is fitted into the notch portion 26.

After that, when the elastic buckle body 11 is rotated again, and the elastic buckle body 11 is moved downward relative to the sleeve bolt shaft 13, the protrusion 16 is relatively moved relative to the elastic buckle body 11, and is pushed away. The claw 17 is locked and fitted to the pocket portion 25. When the upper end of the projection 16 enters the range of the aforementioned gap, the front end portion of the locking claw 17 falls into the engaging portion 36 to lock the tie bar 15. By the locking, the tie rod 15 is prevented from moving downward. Further, the projection 16 is also restricted from inclining to the notch portion 26 by more than a certain extent.
