11. The stop ring of claim 2, wherein the locking pin can be fixed in initial position and in locking position.

12. The stop ring of claim 11, wherein the ball of a ball locking pin enters counterbores for fixing a final position, the initial position and the locking position.

13. The stop ring of claim 12, wherein a bore is provided in the bottom of the support eye lug for mounting the bearing rollers.

14. The stop ring of claim 1, wherein a bore is provided in the bottom of the support eye lug for mounting the bearing rollers.

15. The stop ring of claim 14, wherein the bore in the bottom of the support eye lug is sealed with a plug.

16. The stop ring of claim 1, wherein the threaded pin is equipped with a collar.

17. The stop ring of claim 16, wherein a labyrinth seal is provided in the collar.

18. The stop ring of claim 17, wherein an annular gap between the bottom of the support eye lug and the collar of the threaded pin sealed with a sealing ring.

19. The stop ring of claim 18, wherein the annular gap between the bottom of the support eye lug and the collar of the threaded pin is sealed with a sealing ring.

20. The stop ring of claim 2, wherein the threaded pin is equipped with a collar.

DETAILED DESCRIPTION

(9) FIG. 1 shows a stop ring 1 with a support eye lug 2 and a bottom 3 designed as a bearing bore 4, in which a bearing journal 5 of the threaded pin 6 is arranged. In order to create a form-fitting connection between the support eye lug 2 and the threaded pin 6, and to facilitate a smooth rotational movement of the support eye lug 2 relative to the threaded pin 6, bearing rollers 8 are inserted between the bearing bore 4 and the bearing journal 5 through an opening 7 in the bottom 3 of the support eye lug 2. The opening 7 is closed by a sealing plug 9. The plug 9 can be pressed in, punched in or glued in. In order to protect the bearing against contamination, the collar 10 of the threaded pin 6 is equipped with a labyrinth seal 11 and a sealing ring 12. The locking pin 13 is shown in its initial position in FIG. 1.

(10) FIG. 2 shows the locking mechanism between the support eye lug 2 and the threaded pin 6 via the locking pin 13. The head of the bearing journal 5 of the threaded pin 6 is equipped with a slot 15, into which a section of the locking pin 13 can extend after it is turned by 180. In the initial position of the locking pin 13 shown here, no contact can be made between the locking pin 13 and the bearing journal 5, as the locking element 13 has a recess 16 in the area of the bearing journal 5, said recess 16 extending over a length that at least equals the diameter of the bearing journal 5. The support eye lug 2 therefore is freely rotatable against the threaded pin 6 screwed into an object to be lifted or fixed.

(11) The view in FIG. 3 shows the adjusting lever 14, with which the locking pin 13 can be turned from its initial position shown here to its locking position.

(12) The drawing in FIG. 4 shows the locking process between the support eye lug 2 and the threaded pin 6 via the locking pin 13. Using the adjusting lever 14, which is accessible from the outside, the locking pin 13 is rotated by 180, such that the section of the locking pin, which is located opposite from the recess 16, protrudes into the slot 15 of the bearing journal 5. In this locked position, it is no longer possible to rotate the support eye lug 2 relative to the threaded bearing journal 5. Thus, the threaded pin 6 can be screwed into an object to be lifted or fixed without additional tools, by rotating the support eye lug 2.

(13) FIG. 5 shows a side view of the stop ring 1 with the adjustment lever in its locked position. FIG. 6 shows the front view of the stop ring shown in FIG. 5, in which the positioning of the ball locking pin 17, by which the locking pin 13 can be fixed into its initial and locking positions, is visible.

(14) FIG. 7 shows an enlarged detail of the area of the locking pin 13 and of a ball locking pin 17, which is known from the art. Depending on the position of the locking pin, either its initial position or its locking position, the spring-loaded ball of the ball locking pin 17 enters the counterbore 18 or 19 of the locking pin 13. Thus, when swiveling the locking element 13 via the adjusting lever 14, the ball must be pushed into the ball locking pin against the spring force pressing against the ball. Thus, any spontaneous transition from the initial position to the locking position or vice versa is prevented.
