Description

Technical Field

[0001] This utility model relates to the field of retaining ring technology, and in particular to a high-strength retaining ring. Background Technology

[0002] Snap rings, also known as retaining rings, are divided into retaining rings for holes and retaining rings for shafts. They serve to limit axial movement and prevent other parts from moving axially. Flat retaining rings are separable, basically flat washers, and their inner or outer parts are used as retaining edges for the outer or inner rings of radial cylindrical roller bearings.

[0003] For example, the authorized announcement number "CN214424864U" is named a high-strength automotive retaining ring that prevents lateral movement. It uses front and rear retaining blocks that are installed alternately to reduce heat transfer to the retaining ring, preventing thermal expansion and contraction from affecting its normal use. It also makes the fit between the retaining ring and the pin more tight. The pin is more stably clamped by the opposing ratchet teeth on the front and rear ratchet blocks. The inner support layer is made of stainless steel, and the outer retaining ring layer is made of manganese steel, which makes the overall strength of the retaining ring higher.

[0004] The above-mentioned and existing technologies have the following defects: the car retaining ring only relies on its own elasticity to be engaged with the pin shaft, which is at risk of falling off after long-term use; the ratchet block and the pin shaft do not have any further fastening measures, and there is still a problem of unstable engagement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-strength retaining ring.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-strength retaining ring is designed, comprising a retaining ring body. A snap-fit ​​assembly is arranged circumferentially on the inner wall of the retaining ring body. The snap-fit ​​assembly includes multiple front snap blocks and multiple rear snap blocks arranged in an alternating pattern. The multiple front snap blocks are movably connected to front ratchet blocks via sliding components, and the multiple rear snap blocks are movably connected to rear ratchet blocks via sliding components. The ratchet directions of the front and rear ratchet blocks are opposite to each other. Each front and rear snap block has a threaded hole on its surface. A clamping post is threaded into the inner wall of the threaded hole. One end of the clamping post passes through the threaded hole and is rotatably connected to either the front or rear ratchet block. The other end of the clamping post passes through the retaining ring body and has a nut. The surface of the nut away from the clamping post has an operating groove. A first connecting block and a second connecting block are respectively provided at both ends of the retaining ring body. A locking component is provided between the first and second connecting blocks. Each of the first and second connecting blocks has an operating block at one end, and both operating blocks have through holes on their surfaces.

[0008] Preferably, the sliding assembly includes a sliding rod and a sliding groove. The front ratchet block has two sliding rods on the side surface near the locking assembly, and the rear ratchet block also has two sliding rods on the side surface near the locking assembly. The front locking block has two sliding grooves on the side surface near the front ratchet block, and the rear locking block also has two sliding grooves on the side surface near the rear ratchet block. The sliding rods extend into the corresponding sliding grooves and slide in connection with them.

[0009] Preferably, a T-shaped groove is provided on one side surface of both the front ratchet block and the rear ratchet block, and a T-shaped block is provided on one side surface of both the front locking block and the rear locking block, and the T-shaped block is rotatably connected to the T-shaped groove.

[0010] Preferably, the outer surface of the retaining ring body has a concealed groove corresponding to the front and rear retaining blocks, and the nut is disposed inside the concealed groove.

[0011] Preferably, the cross-section of the operating groove is a regular hexagon.

[0012] Preferably, the locking assembly includes a hinge groove, a snap-fit ​​groove, a rotating block, a lead screw, and a nut. The hinge groove is formed on one side surface of the first connecting block, and the snap-fit ​​groove is formed on one side surface of the second connecting block. The rotating block is rotatably connected to the inner wall of the hinge groove. A lead screw is provided at one end of the rotating block. The lead screw extends out of the snap-fit ​​groove and is threadedly connected to a nut.

[0013] The high-strength retaining ring proposed in this utility model has the following advantages: the retaining ring not only relies on its own elasticity to engage with the pin, but also pushes the ratchet block to further engage with the pin through the clamping post, avoiding the risk of falling off after long-term use; the locking component is set up so that when the retaining ring body is opened by inserting the snap ring pliers into the through hole and then installed on the pin, the screw is rotated to extend into the engagement groove, and the nut is tightened to lock it, so that the ratchet block and the pin are further secured, avoiding unstable engagement.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-4 A high-strength retaining ring includes a retaining ring body 1. A snap-fit ​​assembly is arranged in a circumferential array on the inner wall of the retaining ring body 1. The snap-fit ​​assembly includes multiple front snap-fit ​​blocks 2 and multiple rear snap-fit ​​blocks 3 arranged in an alternating manner. The multiple front snap-fit ​​blocks 2 are movably connected to front ratchet blocks 4 via sliding components, and the multiple rear snap-fit ​​blocks 3 are movably connected to rear ratchet blocks 5 via sliding components. The ratchet directions of the front ratchet blocks 4 and rear ratchet blocks 5 are opposite to each other. Screw holes 6 are formed on the surfaces of both the front snap-fit ​​blocks 2 and rear snap-fit ​​blocks 3. A clamping post 7 is threadedly connected to the inner wall of the screw hole 6. One end of the clamping post 7 passes through the screw hole 6 and is rotatably connected to the front ratchet block 4 or the rear ratchet block 5. The other end of the clamping post 7 passes through the retaining ring body 1 and is provided with a nut 8. The surface of the nut 8 away from the clamping post 7 is provided with an operating groove 9. The two ends of the retaining ring body 1 are respectively provided with a first connecting block 10 and a second connecting block 11. A locking component is provided between the first connecting block 10 and the second connecting block 11. One end of the first connecting block 10 and the second connecting block 11 is provided with an operating block 12. The surfaces of the two operating blocks 12 are provided with through holes 13.

[0021] The sliding assembly includes slide rods 14 and slide grooves 15. Two slide rods 14 are provided on the surface of the front ratchet block 4 near the engaging assembly, and two slide rods 14 are also provided on the surface of the rear ratchet block 5 near the engaging assembly. Two slide grooves 15 are formed on the surface of the front latching block 2 near the front ratchet block 4, and two slide grooves 15 are also formed on the surface of the rear latching block 3 near the rear ratchet block 5. The slide rods 14 extend into the corresponding slide grooves 15 and slide slidably connect with them. By sliding the slide rods 14 within the slide grooves 15, the front ratchet block 4 and the rear ratchet block 5 can only move and cannot rotate.

[0022] Both the front ratchet block 4 and the rear ratchet block 5 have T-shaped grooves 16 on one side surface, and both the front locking block 2 and the rear locking block 3 have T-shaped blocks 17 on one side surface. The T-shaped blocks 17 are rotatably connected to the T-shaped grooves 16. By rotating the T-shaped blocks 17 within the T-shaped grooves 16, the clamping post 7 can push the front ratchet block 4 and the rear ratchet block 5 inward.

[0023] The outer surface of the retaining ring body 1 has concealed grooves 18 that correspond one-to-one with the front retaining block 2 and the rear retaining block 3, and the nut 8 is placed inside the concealed grooves 18. The concealed grooves 18 serve to conceal the nut 8 and prevent the nut 8 from protruding from the retaining ring body 1.

[0024] The operating slot 9 has a regular hexagonal cross-section, which facilitates operation using an internal hexagonal socket.

[0025] The locking assembly includes a hinge groove 19, a snap-fit ​​groove 20, a rotating block 21, a lead screw 22, and a nut 23. The hinge groove 19 is provided on one side surface of the first connecting block 10, and the snap-fit ​​groove 20 is provided on one side surface of the second connecting block 11. The rotating block 21 is rotatably connected to the inner wall of the hinge groove 19. The lead screw 22 is provided at one end of the rotating block 21. The lead screw 22 extends out of the snap-fit ​​groove 20 and is threadedly connected to the nut 23.

[0026] Working principle: The retaining ring body 1 is installed on the pin. The front ratchet block 4 and the rear ratchet block 5 are in contact with the outer surface of the pin. The ratchet teeth of the front ratchet block 4 and the rear ratchet block 5, which are opposite in direction, clamp the pin. By using an Allen wrench to reach into the operating groove 9 and turn the nut 8, the clamping post 7 is rotated and pushes the ratchet block, so that the front ratchet block 4 and the rear ratchet block 5 further clamp the pin. This retaining ring not only relies on its own elasticity to clamp onto the pin, but also pushes the ratchet block to further clamp the pin through the clamping post 7, avoiding the risk of falling off after long-term use. The locking component is set up so that when the retaining ring body 1 is opened by inserting the snap ring pliers into the through hole 13 and then installed on the pin, the screw 22 is rotated to reach into the locking groove 20, and the nut 23 is turned to lock it, so that the ratchet block and the pin are further tightened, avoiding unstable clamping.
