Description

Technical Field

[0001] This utility model relates to the field of cable protection technology, and specifically to a cable protection component that resists bending. Background Technology

[0002] Existing cable joint anti-bending technologies are mainly divided into two categories: structural reinforcement type and dynamic protection type, but both have significant technical defects.

[0003] Structural reinforcement solutions enhance structural rigidity through slotted or hollowed-out designs or zigzag-shaped storage cavities. While these solutions can resist bending in the short term, long-term use can easily lead to stress concentration, resulting in accelerated fatigue and aging of local materials and insufficient actual bending life.

[0004] Dynamic protection solutions use elastic rubber sleeves or telescopic components to limit the bending angle. Although they have a certain degree of deformation adaptability, under dynamic working conditions such as dragging and torsion, their material wear resistance is insufficient and they cannot effectively disperse frictional stress, resulting in a rapid decline in protective effectiveness.

[0005] Both types of solutions share three core drawbacks: First, the anti-bending structure and the sealing system are independent of each other, and structural gaps are easily generated during bending, leading to water seepage or component loosening, resulting in poor coordination between protection and sealing; Second, the system integration is low, and existing technologies generally require modification of the cable body or the addition of multiple independent components, which increases both installation complexity and maintenance costs; Third, the dynamic adaptability is insufficient, as it is impossible to achieve uniform stress distribution through structural optimization, and there is a lack of a synchronous response mechanism to the complex mechanical environment (the coexistence of bending stress and drag friction), resulting in a significantly increased probability of protection failure.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example:

[0034] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses a bending-resistant cable protection component, including a connecting component 10 and an elastic component 20. The connecting component 10 has a through hole extending through both ends of it. The connecting component 10 includes a positioning part and an mounting part. The positioning part can determine the position on the device 60 (such as a control handle) where the cable protection component needs to be installed. Then, the mounting part fixes the positioning part on the device 60 to prevent it from loosening.

[0035] The positioning part and the mounting part form a detachable structure, so that the cable protection component can be detachably mounted on the equipment 60 (control handle).

[0036] One end of the elastic component 20 is disposed on the connecting component 10. The interior of the elastic component 20 is a hollow structure. The elastic component 20 can be bent and can automatically recover after bending.

[0037] In addition, the hollow structure inside the elastic component 20 and the through hole on the connecting component 10 form a cable channel 30, through which the cable of the device 60 (control handle) passes during installation.

[0038] The working principle of this embodiment is that by setting an elastic component 20 on the connecting component 10, and passing the cable in the cable channel 30 within the connecting component 10 and the elastic component 20, the cable is installed on the control handle through the connecting component 10, and then the bending angle of the cable is limited by the elastic component 20 to prevent the cable from being in a bent state for a long time, thereby improving the adaptability of the cable joint.

[0039] In one specific embodiment:

[0040] A protective layer 40 is also provided at the end of the connecting component 10. The protective layer 40 is also a hollow structure and is disposed inside the elastic component 20. The cable channel 30 described above is formed by the hollow structure of the protective layer 40 and the through-hole structure of the connecting component 10.

[0042] In another specific embodiment:

[0043] The elastic component 20 is rotatably connected to the end of the connecting component 10, and the protective layer 40 is fixedly connected to the connecting component 10. This design allows the elastic component 20 to rotate relative to the protective layer 40 and the cable, thereby converting the sliding friction between the cable and the ground or between the elastic component 20 and the ground into rolling friction when the cable is dragged, thus reducing the wear of the elastic component 20.

[0044] Preferably, a bearing 50 is provided between the elastic component 20 and the connecting component 10, the connecting component 10 is connected to the inner ring of the bearing 50, and the elastic component 20 is connected to the outer ring of the bearing 50, thereby realizing the free rotation of the elastic component 20.

[0045] In another specific embodiment:

[0046] The positioning part includes a connector 11, which is a rotating body and has an overall T-shaped structure. The connector 11 has a through hole in the middle, which is the through hole on the connecting assembly 10. One end of the connector 11 is provided with an external thread.

[0047] The mounting section includes a mounting ring 12 with internal threads to mate with the connector 11. The resilient assembly 20 is then mounted by passing the connector 11 through a hole in the housing of the device 60 (control handle) for cable passage and securing the connector 11 to the housing of the device 60 (control handle) via the mounting ring 12.

[0048] In another specific embodiment:

[0049] The positioning part is provided with a latch 13, and the protective layer 40 is connected to the positioning part through the latch 13. The elastic component 20 is provided on the latch 13. The connecting component 10, the protective layer 40 and the elastic component 20 are connected as a whole by the latch 13.

[0050] In another specific embodiment:

[0051] The interior of the latch 13 is a stepped hole, and one end of the protective layer 40 has an outwardly extending connecting plate. The connecting plate of the protective layer 40 is placed at the end of the positioning part, and the smaller diameter section of the latch 13 is engaged with the connecting plate.

[0052] In another specific embodiment:

[0053] The top of the latch 13 is connected to the inner ring of the bearing 50. An annular support ring 51 is provided on the outer ring of the bearing 50. The cross-section of the support ring 51 is L-shaped. One end of the elastic component 20 is fixedly installed on the support ring 51.

[0054] Preferably, the elastic component 20 includes a spring, and the length of the spring is less than the length of the protective layer 40.

[0055] In this embodiment, a support ring 51 is provided to provide a structure with sufficient strength for the spring.

[0056] In another specific embodiment:

[0057] The protective layer 40 is made of soft rubber, which utilizes the wear-resistant and flexible properties of rubber to protect the cable while preventing it from being worn.

[0058] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
