[0025] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0026] like Figures 1-5 As shown, a cable sheath protector according to this application includes a sheath clamping ring 1, an elastic pressure block 2, a connecting screw 3, a protective cover 4, and a fastening element 5. Each component is described in detail below.

[0027] The sheath clamping ring 1 is a circular structure designed to firmly wrap and fix the cable sheath. Specifically, the sheath clamping ring 1 has an appropriate curved surface shape inside, which allows it to conform to the shape of the cable sheath in the axial direction, thereby enhancing the uniformity and stability of the contact. Technically, this function can be achieved by making the material into stainless steel or aluminum-based alloys, which have high toughness and are easy to machine.

[0028] The elastic pressure block 2, through its specific structural design, can provide radial elastic support to the inner diameter after being compressed. Multiple protrusions are arranged on the outer surface of the elastic pressure block 2, increasing friction during contact with the protective clamping ring 1, thereby improving the overall internal support effect of the device. This component can be injection molded from elastic rubber material, utilizing the material's naturally high resilience to meet practical requirements.

[0029] The connecting screw 3 is a through-type component that passes through the sheath clamping ring 1 and engages with the snap-fit ​​element 5 via a threaded connection to complete the final locking operation. To ensure sufficient resistance to loosening under high-intensity vibration environments, it can be made of high-grade steel that has been hardened and surface-treated, and the thread specifications can be optimized, such as increasing the thread depth or improving the thread profile angle. This not only improves strength but also effectively avoids overload damage that may occur during conventional assembly.

[0030] The protective cover 4 is arranged around the outside of the protective layer clamping ring 1, mainly to protect it from the risk of damage caused by harsh external factors, such as chemical solvent corrosion or aging damage under extreme temperature conditions. The edge of the protective cover 4 needs to have reserved interface positions to facilitate the insertion and fixation of other components without obstruction.

[0031] The design of the snap-fit ​​component 5 is complex yet highly practical. On one hand, it achieves a secure fastening effect through precise matching with the connecting screw 3; on the other hand, it incorporates several detailed features to further enhance the overall system functionality. Among these features, the arc-shaped guide surface 51 assists in directional adjustment and smooth entry during quick and accurate installation, significantly reducing the chance of misoperation. The anti-slip texture 52 effectively prevents accidental loosening during use, especially crucial when frequent opening and closing or when lubricant is present. The internally embedded reinforcing rib structure greatly improves the resistance of localized areas to torsional deformation, maintaining long-term reliable connection quality under repeated loading.

[0032] To address the technical challenge of improving assembly efficiency while reducing the possibility of loosening, a cable sheath protector offers the following solution:

[0033] Firstly, in terms of component structure, the snap-fit ​​component 5 is equipped with a unique arc-shaped guide surface 51. This design simplifies the assembly process; when the snap-fit ​​component 5 is installed at the predetermined point, it can naturally embed itself into place without much manual correction, significantly saving time and labor costs. Furthermore, the anti-slip texture 52 on its surface reduces the risk of rotational slippage during repeated loading and unloading or impacts from the external environment, thus preventing loosening at the mechanism level. Secondly, the connecting screw 3 ensures reliability during the locking stage through precise control of material properties and manufacturing precision. The entire device relies on the combination of the protective clamping ring 1 and the elastic pressure block 2 to establish a stable support system, maintaining high resistance to deformation and overall rigidity even in the face of stress variations generated during long-term operation.

[0034] like Figure 5As shown, in one embodiment, the design of the clip 5 of the cable sheath protector of this application has significant features. One end of the clip 5 is used for threaded connection with the connecting screw 3, and the other end forms a stable clip structure. To facilitate assembly, the clip 5 is provided with an arc-shaped guide surface 51 on its exterior, which achieves a smooth transition between the contact surfaces. This design not only helps to reduce frictional damage that may occur during installation, but also allows the clip 5 to be quickly aligned to the predetermined position through the guide structure, thereby improving the installation accuracy and convenience of the connecting screw 3. In addition, the clip 5 contains a gradient guide groove 6 inside, the width of which gradually narrows from the inlet inward, thus serving a dual function of positioning and guiding.

[0035] For example, in the manufacturing process of the snap fastener 5, a one-piece molding process is adopted, and a smooth arc-shaped transition area is designed on its outer surface as a guide surface to ensure that it can seamlessly adapt to relative displacement during assembly. Specifically, the guide groove 6 can be constructed with a gradually changing geometry through precision machining or mold forming technology to ensure that the connecting screw 3 can smoothly enter the thread engagement stage with the assistance of the guide groove and lock securely. At the same time, the overall position of the snap fastener 5 must be consistent with the axis of the connecting screw 3, and its opening direction should facilitate the operation of assembly tools to further optimize the overall functionality.

[0036] like Figure 5 As shown, in one embodiment, the anti-slip structure design of the clip 5 of the cable sheath protector of this application includes an alternating arrangement of transverse grooves and longitudinal protrusions. By adding this unique texture to the surface of the clip 5, it can generate a more reliable frictional engagement with external objects when the device is locked. This design avoids the risk of loosening due to environmental vibration or external impact, thereby ensuring long-term reliability. In addition, the anti-slip texture 52 is located on the exposed part of the clip 5, which does not affect the threaded connection between the internal connecting screw 3 and the clip 5, and also maximizes its function.

[0037] Specifically, injection molding can be used to integrate the anti-slip texture 52 during the production of the buckle 5. For example, by designing a special mold cavity with crisscrossing ridges inside, these ridges will naturally imprint corresponding transverse grooves and longitudinal protrusions 7 during cooling and molding. This method not only reduces subsequent processing steps but also ensures structural accuracy and appearance consistency, making it suitable for large-scale production needs.

[0038] like Figure 5As shown, in one embodiment, the design of the clip 5 of the cable sheath protector of this application introduces a structural innovation. The clip 5 has reinforcing ribs inside to improve local strength, and these ribs extend to the outer surface of the clip 5 to form external reinforcing ridges 8. This structure extends the functional design originally hidden inside to the outside, enabling the clip 5 to further enhance its overall resistance to deformation while meeting mechanical performance requirements, making it suitable for cable fixing under long-term operation or special working conditions.

[0039] Specifically, in this structural design, the external reinforcing ribs 8 of the fastener 5 are regularly distributed along its outer wall, corresponding to the positions of its internal reinforcing ribs 53. The presence of these reinforcing ribs does not change the assembly relationship or working principle of the fastener 5 with other components, but rather serves as a reinforcement of the original component structure. Furthermore, by adjusting the shape and size of the external reinforcing ribs 8, personalized adaptation can be achieved according to actual stress requirements. For example, under certain high-intensity working conditions, the number of reinforcing ribs can be increased or the width of the reinforcing ribs can be widened to match different stress environments.

[0040] Specifically, firstly, a suitable metal material is selected to manufacture the buckle 5, ensuring that the position of the reinforcing rib and its outward extension area can be accurately reserved during the one-piece molding process; then, the reinforcing rib is formed by using a mold, and ensuring that the entire component still has the same assembly precision and surface treatment consistency as the connecting screw 3 and the protective clamping ring 1.

[0041] like Figure 4 As shown, in one embodiment, the protective cover 4 and the fastener 5 of the cable sheath protector of this application achieve quick and easy assembly / disassembly via a magnetic connection mechanism. Specifically, a ring magnet 11 is installed inside the protective cover 4, and the ring magnet 11 is arranged around the inner wall of the protective cover 4 to provide a uniform and stable magnetic force distribution. At the same time, a metal mating flange 12 is provided on the fastener 5. This metal mating flange 12 can be attracted by the ring magnet 11, and its precisely designed position and geometric characteristics ensure stable alignment with the protective cover 4.

[0042] For example, a high-strength neodymium iron boron ring magnet 11 can be embedded in a specific slot inside the protective cover 4 for fixation. Then, a metal mating flange 12 made of a high magnetic permeability material is provided on the outer edge of the fastener 5. When the two are connected, the magnetic force will automatically pull the fastener 5 closer and lock it in place. The entire process can be completed efficiently without the need for additional tools.

[0043] like Figure 2As shown in one embodiment, the sheath clamping ring 1 of the cable sheath protector of this application is designed with special structural forms at both ends, with guide bevels 13 provided at these positions. The guide bevels 13, through a certain tilt angle and geometry, form a cooperative relationship with the elastic pressure block 2, ensuring precise distribution and positioning of the two during assembly. In actual operation of the device, due to the effect of the bevels, the elastic pressure block 2 can accurately move along the preset direction to the set contact surface area, thereby avoiding positional deviations during installation and locking, and improving assembly efficiency and reliability.

[0044] For example, during the manufacturing stage of the sheath clamping ring 1, guide bevels 13 with a certain angle are pre-generated by machining or mold casting. Then, in subsequent assembly steps, these bevels are used to effectively guide the position of the elastic block 2. Specifically, when the connecting screw 3 drives the buckle 5 to achieve axial locking, the elastic block 2 is pushed in and distributed along the correct path at the predetermined contact position under the influence of the guide bevels 13.

[0045] like Figure 5 As shown, in one embodiment, the connecting screw 3 of a cable sheath protector of this application has a special structure at one end to enhance the ease of assembly. This end has an exposed pitch amplification area 14, which, compared to a conventional thread structure, has fewer threads per unit length in the axial direction. By increasing the pitch, the thread density is reduced, making it easier for the locking member 5 to align with the connecting screw 3 and engage during the initial screwing stage. This design helps reduce the operational difficulty caused by excessively dense threads during assembly.

[0046] For example, when the snap-fit ​​component 5 needs to be assembled to the connecting screw 3, the exposed pitch amplification area 14 can guide the snap-fit ​​component 5 to complete the initial alignment. Specifically, this special threaded area can effectively reduce the possibility of seizing or stripping when the snap-fit ​​component 5 is screwed in. In actual implementation, precision machining technology can be used to adjust the pitch of the end closest to the snap-fit ​​component 5 separately while maintaining the overall thread accuracy, thereby ensuring that the locking performance is not affected and the assembly efficiency is significantly improved.

[0047] like Figure 2As shown, in one embodiment, the elastic block 2 of a cable sheath protector of this application is externally covered with a low-density elastic buffer layer 15. This buffer layer is made of a flexible material and is tightly fitted to the outside of the elastic block 2, thus forming a double-layer structure. The main function of the buffer layer is to isolate the direct impact of external pressure on the internal structure of the sheath clamping ring 1, while reducing the risk of vibration or impact force being transmitted to the core components of the device. Furthermore, the low-density elastic buffer layer 15 also helps to disperse stress, ensuring that the elastic block 2 maintains its functional shape during compression. Since the buffer layer directly covers the elastic block 2 and is located outside the contact area between the sheath clamping ring 1 and the elastic block 2, the reliability and adaptability of the overall device are further enhanced.

[0048] Specifically, the buffer layer can be coated using an appropriate molding process, such as injection molding or spray coating. Specifically, before assembly, the prefabricated elastic block 2 is placed in a mold for secondary coating, ensuring the low-density elastic buffer layer 15 adheres firmly to its surface. Subsequently, the assembled elastic block 2, along with the buffer layer, is installed into the protective clamping ring 1 to form the final functional structure assembly. This method ensures precise fit between components and achieves the technical characteristics required by the design.

[0049] like Figure 5 As shown, in one embodiment, a limiting and anti-detachment structure is added between the connecting screw 3 and the fastening member 5 of the cable sheath protector of this application. This structure includes a limiting and anti-detachment retaining ring 16 disposed in the connecting screw 3. Specifically, the limiting and anti-detachment retaining ring 16 is fixedly installed in a specific radial groove inside the connecting screw 3, and its outer edge shape is designed to fit the annular groove inside the screw. This fit ensures that the retaining ring remains stable during operation and will not experience circumferential displacement or radial detachment. Furthermore, the limiting and anti-detachment retaining ring 16 itself is made of a material with certain elastic properties, such as high-quality stainless steel or polymer composite materials, thereby enabling it to adapt to different assembly environments through slight elastic deformation.

[0050] For example, a precise radial groove can be pre-machined on the inner wall of the connecting screw 3 to position the retaining ring, which can then be embedded using an interference fit. After assembly, when the locking component 5 is tightened, the meshing force between its thread and the connecting screw 3 is limited by the retaining ring 16, preventing the reaction force from causing the locking component 5 to loosen or rotate. In this way, the entire device can maintain high locking stability for a long time during actual operation.

[0051] like Figure 2As shown, in one embodiment, a positioning guide sleeve 17 is embedded inside the sheath clamping ring 1 of the cable sheath protector of this application. Its main function is to ensure the accuracy and stability of the elastic pressure block 2 during installation. The positioning guide sleeve 17 is located inside the sheath clamping ring 1, surrounding the entire inner cavity and evenly distributed to form a guiding constraint structure. The positioning guide sleeve 17 is made of a wear-resistant material with a certain degree of hardness. Its outer surface is in close contact with the sheath clamping ring 1, while its inner wall cooperates with the elastic pressure block 2. In this way, the positional relationship between the sheath clamping ring 1 and the elastic pressure block 2 is effectively regulated, thereby ensuring the consistency and reliability of the device operation.

[0052] Specifically, this positioning guide sleeve 17 can be embedded into the reserved slot of the sheath clamping ring 1 through interference fit, bonding, or threaded fixing. To achieve a better guiding effect, for example, a guide groove or a tapered slope can be provided on the inner surface of the positioning guide sleeve 17, so that the elastic pressure block 2 gradually aligns and closely contacts the sheath surface during insertion, thereby avoiding tilting or jamming that may occur during assembly. In addition, the structural form of the positioning guide sleeve 17 can also be appropriately adjusted, for example, by adopting a segmented design for subsequent maintenance or replacement.

[0053] In actual operation, when this device is used, the sheath clamping ring 1 can be placed outside the cable sheath first, and the elastic pressure block 2 provides radial elastic support to achieve initial fixation of the cable sheath. Next, the connecting screw 3 is threaded through the sheath clamping ring 1 and connected to the snap fastener 5, thus completing the axial locking operation of the device. During this process, the protective cover 4 surrounds the outside of the sheath clamping ring 1, preventing external environmental factors from corroding the sheath clamping ring 1. One end of the snap fastener 5 is firmly connected to the connecting screw 3, and the other end is aided in the assembly of the device by the arc-shaped guide surface 51. The anti-slip texture 52 added to its surface reduces the possibility of loosening, and the internal reinforcing ribs improve the overall structural strength, thereby ensuring that the entire cable sheath protector can maintain a stable and reliable operating state during use.
