The plurality of first angular grooves are formed on the upper surface of the retaining ring body, and the plurality of second angular grooves are also formed on the upper surface of the retaining ring body. The first angular grooves and the second angular grooves are arranged alternately. The left inner wall of the first angular groove is an inclined surface, and the right inner wall of the second angular groove is an inclined surface.

[0012] Preferably, a plurality of first angular grooves are evenly distributed on the upper surface of the retaining ring body and the number of such grooves is four, and a plurality of second angular grooves are evenly distributed on the upper surface of the retaining ring body and the number of such grooves is four.

[0013] The present invention proposes an internal four-sided anti-rotation self-locking retaining ring, which has the following advantages: the retaining ring has strong integrity and high strength, and is installed and fixed firmly by threaded connection with parts with internal threaded holes through threaded grooves; the reinforcement device, through the setting of reinforcement rings and multiple connecting ribs, further strengthens the strength of the retaining ring body and avoids failure under axial impact force; the retaining ring is equipped with a clamping device, which makes the bolt column clamp against the part with internal threaded hole, so that the internal threaded hole holds the column threaded groove, preventing the retaining ring body from rotating.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3An internal square anti-rotation self-locking retaining ring includes a retaining ring body 1, a support plate 2 on the inner wall of the retaining ring body 1, an internal square hole 3 on the surface of the support plate 2, a raised edge 4 on the inner wall of the internal square hole 3, a reinforcing device between the raised edge 4 and the inner wall of the retaining ring body 1, a threaded groove 5 spirally opened on the surface of the retaining ring body 1, and multiple oil injection holes 6 on the inner wall of the retaining ring body 1. Lubricating oil is injected through the oil injection holes 6, which can facilitate the removal of the retaining ring body 1 from the part with the internal threaded hole. Multiple clamping devices are provided on the inner wall of the retaining ring body 1, and a disassembly and assembly assembly is provided on the upper surface of the retaining ring body 1.

[0020] The reinforcing device includes a reinforcing ring 7 and multiple connecting ribs 8. The reinforcing ring 7 is circumferentially positioned at the corner between the support plate 2 and the inner wall of the retaining ring body 1. The multiple connecting ribs 8 are positioned between the reinforcing ring 7 and the raised edge 4. This retaining ring has strong integrity and high strength. It is installed and fixed by threaded connection with parts with internal threaded holes through threaded grooves 5, ensuring a secure installation. The reinforcing device, through the reinforcing ring 7 and multiple connecting ribs 8, further strengthens the strength of the retaining ring body 1, preventing failure under axial impact forces.

[0021] The clamping device includes a screw hole 9, which is opened in the inner wall of the retaining ring body 1, and a bolt post 10 is threadedly connected to the inner wall of the screw hole 9.

[0022] The bolt post 10 has an internal hexagonal groove 11 on the side surface near the internal square hole 3.

[0023] The assembly / disassembly component includes multiple first angled grooves 12 and multiple second angled grooves 13. The first angled grooves 12 are formed on the upper surface of the retaining ring body 1, and the second angled grooves 13 are also formed on the upper surface of the retaining ring body 1.
