Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal C-ring technology, and in particular to a helical spring reinforced metal C-ring. Background Technology
[0002] Snap rings, also known as retaining rings or retaining rings, are common fasteners in mechanical assembly. They are installed in shaft grooves or hole grooves to prevent axial displacement of related parts. Their main material is 65Mn spring steel, and they can be divided into two categories according to their shape: shaft-type and hole-type. Among them, C-type snap rings are widely used in the automotive, hardware, and electronics industries due to their versatility.
[0003] Existing C-type retaining rings are often single-layered, relying on the strength and toughness of the material itself to be installed in the groove. However, for some shafts with larger diameters or holes with larger diameters, their strength may be insufficient, leading to failure of the limiting function. Utility Model Content
[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a helical spring reinforced with metal C-ring.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a helical spring reinforced metal C-ring, comprising a C-ring body, wherein mounting holes are provided at both ends of the C-ring body, and a reinforcing structure is provided on the upper side of the C-ring body, the reinforcing structure comprising a side ring cover, an outer ring, an inner spring, an inner ring, an outer ring reinforcing rib, and an end cover, wherein the outer ring, the inner ring, and the end cover are integrally cold-rolled on one side of the C-ring body, the inner spring is located in the gap between the outer ring and the inner ring, and the two ends of the inner spring are respectively welded to the sides of the two sets of end covers.
[0006] Preferably, the side ring cover is welded onto the outer ring, the inner ring, and the two sets of end caps.
[0007] Preferably, multiple sets of parallel outer ring reinforcing ribs are integrally cold-rolled and formed on the outer side of the outer ring.
[0008] Preferably, the upper side of the C-shaped ring body is integrally cold-rolled with multiple sets of annularly distributed radial reinforcing ribs, and the multiple sets of radial reinforcing ribs are located on the outer side of the outer ring.
[0009] Preferably, the curvature of both the outer ring and the inner ring is consistent with the curvature of the inner edge of the C-shaped ring body.
[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0011] 1. In this utility model, the curvature of the outer and inner rings is consistent with the inner edge of the C-ring body, avoiding interference with the normal installation of the C-ring body. When the C-ring body is inserted into the groove, the built-in spring between the outer and inner rings is stretched to generate elastic force, which is transmitted to both ends of the C-ring body through the end cap, causing it to expand outward, thereby tightly engaging the groove and effectively improving the limiting effect on shafts or holes with larger diameters.
[0012] 2. In this utility model, the outer ring, inner ring and end cap on one side of the C-shaped ring body are integrally cold-rolled to ensure the structural integrity with the C-shaped ring body and prevent the parts from loosening. At the same time, the multiple sets of parallel outer ring reinforcing ribs on the outer side of the outer ring can disperse external stress and prevent breakage. The radial reinforcing ribs distributed in a ring on the upper side of the C-shaped ring body can provide uniform support and avoid permanent damage caused by external deformation. This comprehensively improves the strength and toughness of the device and extends its service life. Attached Figure Description

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0019] Example: Figure 1 - Figure 3As shown, this utility model provides a helical spring reinforced metal C-ring, including a C-ring body 1. Both ends of the C-ring body 1 have mounting holes 2, providing precise force application points for subsequent operation with pliers. This allows the two tips of the pliers to be inserted separately, achieving precise clamping and slight compression of the C-ring body 1, creating convenient conditions for inserting it into the groove. A reinforcing structure 4 is provided on the upper side of the C-ring body 1. The reinforcing structure 4 includes a side ring cover 41, an outer ring 42, an internal spring 43, an inner ring 44, an outer ring reinforcing rib 45, and an end cap 46. As the core reinforcing component of the C-ring body 1, it is used to synergistically improve the structural strength, toughness, and stability of the C-ring body 1 after installation, to meet the limiting requirements of shafts or holes with larger diameters. The outer ring 4... 2. The inner ring 44 and the end cap 46 are integrally cold-rolled on one side of the C-ring body 1. This forming method ensures that the three components form a structural integrity with the C-ring body 1. It ensures that the outer ring 42 and the inner ring 44 can match the inner edge curvature of the C-ring body 1 to fit tightly against the inner wall of the groove. It also ensures that the end cap 46 can stably bear the elastic force transmitted by the built-in spring 43, avoiding loosening of the connection between the components. The built-in spring 43 is located in the gap between the outer ring 42 and the inner ring 44. The two ends of the built-in spring 43 are welded to the sides of the two sets of end caps 46 respectively. The welding connection can ensure the stability of the connection between the built-in spring 43 and the end cap 46. When the C-ring body 1 is inserted into the groove due to its own toughness, the built-in spring 43 can be stretched synchronously with the deformation of the C-ring body 1, thereby generating continuous elastic force.
[0020] like Figure 1 - Figure 2 As shown, the side ring cover 41 is welded to the outer ring 42, the inner ring 44 and the two sets of end covers 46 to prevent the built-in spring 43 from slipping out of the gap. At the same time, the welding strengthens the connection stability between the components of the reinforced structure 4, further ensuring the overall performance of the reinforced structure 4.
[0021] like Figure 2 and Figure 3 As shown, multiple sets of parallel outer ring reinforcing ribs 45 are integrally cold-rolled on the outside of the outer ring 42, which can evenly distribute the external stress borne by the outer ring 42, prevent the outer ring 42 from breaking due to local stress concentration, and effectively enhance the toughness and deformation resistance of the outer ring 42.
[0022] like Figure 1 - Figure 3 As shown, the upper side of the C-shaped ring body 1 is integrally cold-rolled with multiple sets of annularly distributed radial reinforcing ribs 3. The multiple sets of radial reinforcing ribs 3 are located on the outside of the outer ring 42. The annular distribution can provide uniform support to the upper area of the C-shaped ring body 1, strengthen the overall strength of the C-shaped ring body 1, prevent permanent damage when it is deformed by external force, and extend the service life of the device.
[0023] like Figure 1 - Figure 3As shown, the curvature of both the outer ring 42 and the inner ring 44 is consistent with the curvature of the inner edge of the C-ring body 1, ensuring that after the C-ring body 1 is inserted into the groove, the inner ring 44 can fit tightly with the C-ring body 1 and the outer side of the shaft, improving the fit and overall structural stability after installation.
[0024] The method of use and working principle of this device: When in use, the two tips of the pliers are passed through the two sets of mounting holes 2 respectively, and the shape of the C-ring body 1 is slightly compressed and inserted into the groove. The outer ring 42 and the inner ring 44 are close to or even the same as the edge curvature of the C-ring body 1. They are integrally cold-rolled with the C-ring body 1 to enhance the strength and toughness of the C-ring body 1. At the same time, multiple sets of parallel outer ring reinforcing ribs 45 are integrally cold-rolled on the outside of the outer ring 42 to enhance the toughness of the outer ring 42. The end cap 46 is used to connect the built-in spring 43. The radial reinforcing ribs 3 are distributed in a divergent manner to enhance the strength of the C-ring body 1. When the C-ring body 1 is inserted into the groove due to its toughness, the built-in spring 43 will be stretched to generate elastic force. This elastic force acts on the end cap 46 and is transmitted to both ends of the C-ring body 1, so that the two ends of the C-ring body 1 tend to expand outward, thus tightly locking in the groove and improving the limiting effect on shafts or holes with larger diameters.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
