[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-5 The present invention provides a technical solution, including the following embodiments:

[0027] Example 1

[0028] Combination Figure 1 and Figure 4 As shown, this embodiment focuses on the tensile-resistant core structure of the adapter.

[0029] Specifically, the adapter includes a mounting head 1 and a plug 11, which are an integral structure. The main cable 3 passes through the mounting head 1 and the plug 11. A mounting ring 21 is fixed to the main cable 3 with adhesive and is movably positioned within a threaded groove in the mounting head 1. When the main cable 3 is subjected to external tension, the mounting ring 21 is confined within the threaded groove, absorbing part of the tension through the elastic deformation of its rubber material, thereby significantly improving the tensile strength of the adapter. Furthermore, a rubber sheath 5 is fixedly installed on the plug 11 and loops around the outer wall of the main cable 3. The protrusions 52 on its inner wall tightly conform to the surface of the main cable 3, forming a compression contact. When the main cable 3 is under tension, the rubber sheath 5 increases the friction with the main cable 3 through the protrusions 52, further assisting in tensile resistance.

[0030] Furthermore, the mounting gasket 21 is a rubber gasket, whose material properties allow for elastic deformation under pressure, filling the gaps in the threaded groove and preventing loosening. Simultaneously, the mounting gasket 21 is fixed to the main cable 3 with adhesive, ensuring it will not shift during long-term use and maintaining stable tensile strength. Through the combined action of the mounting gasket 21 and the rubber sheath 5, the adapter effectively disperses stress when subjected to axial tension, preventing the main cable 3 from detaching from the mounting head 1 and extending its service life. In addition, the raised design 52 of the rubber sheath 5 enhances sealing, preventing moisture and dust intrusion.

[0031] Example 2

[0032] Combination Figure 2 and Figure 5 As shown in the figure, this embodiment describes in detail the bonding mechanism between the rubber sheath 5 and the main cable 3.

[0033] Specifically, the outer wall of the rubber sheath 5 has an annular groove 51, and the protrusions 52 on its inner wall are arranged in an array to increase the contact area with the main cable 3. When the main cable 3 is bent, the rubber sheath 5 absorbs the bending stress through its elasticity, preventing the main cable 3 from being damaged due to excessive bending. The protrusions 52 are made of soft rubber material, which deforms under pressure and fits against the surface of the main cable 3 to form multi-point fixation.

[0034] Furthermore, the design of the protrusion 52 increases the static friction between the protrusion 52 and the main cable 3 when the main cable 3 is under tension. The rubber sheath 5 not only resists bending but also increases adhesion under tensile conditions through the protrusion 52, reducing the axial displacement of the main cable 3. At the same time, the annular groove 51 provides space for subsequent connections, enhancing the adaptability of the overall structure.

[0035] Example 3

[0036] Combination Figure 3 As shown in the figure, this embodiment illustrates the quick installation and locking mechanism of the rubber ring 4 and the mounting sleeve 6.

[0037] Specifically, a rubber ring 4 is fitted onto the plug 11, and multiple extension strips 41 are provided on the rubber ring 4. These extension strips 41 are movably disposed within the cutting portion 12 of the plug 11. The rubber ring 4, extension strips 41, and protrusion 42 are an integral structure to ensure mechanical consistency. When the mounting sleeve 6 is threaded onto the plug 11 via the mounting thread 13, the protruding ring 61 on the inner side of the mounting sleeve 6 contacts the inclined surface 43 at the end of the extension strip 41, forcing the extension strip 41 to converge towards the center.

[0038] Furthermore, after the extension bar 41 converges, its end protrusion 42 embeds into the annular groove 51 of the rubber sheath 5, achieving a limiting connection between the rubber sheath 5 and the rubber ring 4. Simultaneously, the mounting sleeve 6 compresses the rubber ring 4, fixing it to the plug 11 and preventing slippage. The convergence of the protrusion 42 also indirectly pushes the protrusion 52 on the inner wall of the rubber sheath 5 to fit more tightly against the main cable 3, increasing adhesion and friction. This mechanism allows for rapid assembly without additional tools; locking can be achieved simply by rotating the thread. The mounting sleeve 6 is made of stainless steel, offering strong corrosion resistance. The movable design of the extension bar 41 absorbs vibration energy and, in conjunction with the rubber sheath 5, provides a certain degree of tensile buffering for the main cable 3.

[0039] Example 4

[0040] Combination Figure 1 and Figure 4 As shown, this embodiment involves the mating of the connector 2 and the mounting gasket 21.

[0041] Specifically, the mounting head 1 has a threaded groove at one end relative to the plug 11, and the connector 2 is mounted in the threaded groove by rotating the thread. The mounting ring 21 is movably mounted in the threaded groove. When the connector 2 is screwed in, it squeezes the mounting ring 21, causing it to deform and fit tightly against the main cable 3 and the inner wall of the threaded groove.

[0042] Furthermore, connector 2 features a stainless steel head, providing high strength and durability. The rubber material of the mounting gasket 21 generates a rebound force after compression, enhancing the clamping force on the main cable 3. When the main cable 3 is under tension, the mounting gasket 21 resists tension through friction and deformation, while the threaded connection provides mechanical interlocking. This structure simplifies the installation process, allowing for quick fixing by rotating connector 2, suitable for scenarios with frequent disassembly. Additional advantages: The replaceable design of the mounting gasket 21 facilitates maintenance; overall, the adapter's multiple tensile-resistant designs enhance reliability, making it suitable for harsh industrial environments.

[0043] Working principle: The main cable 3 runs through it; the mounting ring 21 is fixed to the main cable 3 with glue and is movably set in the threaded groove of the mounting head 1. When the main cable 3 is under tension, the mounting ring 21 is limited in the threaded groove by the elastic deformation of the rubber material, effectively absorbing the tension and improving the tensile strength. At the same time, the rubber sheath 5 is sleeved on the outer wall of the main cable 3, and its inner wall protrusions 52 are tightly attached to the surface of the main cable 3, increasing the friction and further enhancing the tensile effect; the outer wall of the rubber sheath 5 has an annular groove 51, and the inner wall protrusions 52 are distributed in an array to increase the contact area with the main cable 3. When the main cable 3 is bent, the rubber sheath 5 absorbs the stress through elasticity, avoiding excessive bending damage. The protrusions 52 are made of soft rubber, which fits more tightly after being compressed and deformed, forming multi-point fixation and reducing axial displacement; a rubber ring 4 is sleeved on the plug 11, and its extension strip 41 is movably set in the cutting part 12. The mounting sleeve 6 passes through When the installation thread 13 is screwed in, its convex ring 61 contacts the inclined surface 43 at the end of the extension strip 41, forcing the extension strip 41 to converge, so that the convex part 42 is embedded in the annular groove 51 of the rubber sheath 5, realizing the limiting connection. At the same time, the installation sleeve 6 squeezes the rubber ring 4 to fix it to the plug 11. The convergence of the convex part 42 indirectly pushes the convex part 52 to fit more tightly against the main cable 3, increasing the adhesion and friction. This mechanism supports quick assembly without additional tools and works with the rubber sheath 5 to play a tensile buffering role. One end of the installation head 1 has a threaded groove, and the connector 2 is threaded into it. When screwed in, the installation ring 21 is squeezed, causing it to deform and fit tightly against the main cable 3 and the inner wall of the threaded groove. The rubber material of the installation ring 21 generates a rebound force under pressure. When stretched, it resists the stretching through friction and deformation. The threaded connection provides mechanical interlocking, simplifies the installation process, and is suitable for frequent disassembly scenarios. The replaceable design of the installation ring 21 facilitates maintenance and improves overall reliability. Through the synergistic effect of the mounting gasket 21, rubber sleeve 5, rubber ring 4 and mounting sleeve 6, the adapter achieves high tensile strength, bending resistance and quick installation, making it suitable for harsh industrial environments.
