Description

Technical Field

[0001] This utility model relates to the field of snap ring technology, specifically a snap ring structure with a double arc-shaped opening. Background Technology

[0002] A snap ring is a mechanical part, also known as a retaining ring or retaining ring. It can generally be divided into two types: shaft snap rings and hole snap rings. It mainly uses the tension generated by its own elastic deformation to firmly fix related parts in a designated position, preventing them from moving or falling off in the axial direction.

[0003] Most commonly used retaining rings currently employ a C-shaped single-arc open structure. However, this structure has some limitations in practical use. Firstly, it is inconvenient for frequent disassembly. In mechanical applications requiring regular maintenance, repair, or parts replacement, frequent disassembly and assembly of retaining rings is unavoidable. Disassembly of C-shaped single-arc open retaining rings is cumbersome, reducing the efficiency of mechanical maintenance and assembly. Secondly, its anti-loosening effect is poor. During mechanical operation, especially under conditions of vibration, impact, or variable loads, this type of retaining ring may loosen due to its structural limitations, leading to axial displacement of parts or even detachment, potentially causing mechanical failure, affecting the normal operation and service life of equipment, and posing certain safety hazards.

[0004] Based on this, a double-arc-shaped opening snap ring structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a snap ring structure with a double arc-shaped opening to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The double-arc-shaped opening snap ring structure includes a snap ring body, the snap ring body includes a first arc ring, two second arc rings are symmetrically provided at the opening end of the first arc ring, a first rubber pad is embedded in the inner side of the first arc ring, an anti-disengagement component is provided at the connection between the first arc ring and the second arc ring, and an auxiliary disassembly component is provided at one end of the second arc ring.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the inner side of the first arc ring is provided with a first mounting groove for mounting the first rubber pad, and the first mounting groove is provided with a plurality of mounting holes.

[0008] In one alternative: a second mounting groove is provided at the connection between the first arc ring and the second arc ring, a storage groove is provided on the side of the second mounting groove near the first arc ring, a third mounting groove is provided at the upper end of the second mounting groove, and a sealing plate is provided at the upper end of the third mounting groove.

[0009] In one alternative: a slot is provided at one end of the second arc ring, and a fixing post is provided in the slot, and the auxiliary disassembly and assembly component is rotatably connected to the fixing post.

[0010] In one alternative: the first rubber pad is provided with a plurality of connecting posts on the side near the first arc ring, the connecting posts are installed in the mounting holes, and one end of the connecting posts is provided with a limiting block.

[0011] In one alternative: the anti-detachment component includes a triangular anti-detachment block, which is rotatably mounted in a second mounting groove via a connecting shaft. The triangular anti-detachment block has anti-slip teeth on the side near the first arc ring, and a torsion spring is provided at the upper end of the connecting shaft. The torsion spring is disposed in a third mounting groove.

[0012] In one alternative: the auxiliary disassembly and assembly assembly includes a rotating plate, which is disposed in a slot, one end of which is rotatably connected to a fixed post, and the other end of which is provided with an opening.

[0013] In one alternative: the rotating plate is provided with a second rubber pad at both the top and bottom, and one side of the second rubber pad is in frictional contact with the upper and lower sidewalls of the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up an auxiliary disassembly and assembly component, the operator can easily insert a tool through the opening of the rotating plate when disassembling the retaining ring. By rotating the rotating plate, the retaining ring can be easily pried up from the installation position by means of the lever principle, which greatly improves the convenience of disassembly and assembly.

[0015] 2. This utility model, by setting an anti-detachment component, allows the triangular anti-detachment block to rotate and retract into the storage groove under pressure during snap ring installation, facilitating snap ring installation. Once the snap ring is in place, the triangular anti-detachment block rotates out of the storage groove under the action of the torsion spring. When the snap ring shows a tendency to loosen, the triangular anti-detachment block cannot rotate outward, thus preventing the snap ring from loosening and effectively preventing it from loosening under mechanical vibration, impact, or variable load conditions.
