Description

Technical Field

[0001] The utility model relates to the technical field of cable protective sleeves, in particular to a cable protective sleeve with enhanced protection. Background Art

[0002] In fields such as power transmission and industrial automation, cables serve as an important transmission medium, carrying both signals and power. However, cables often face harsh external environments during use, including mechanical shock, vibration, moisture, corrosive chemicals, and high temperatures. These factors can cause severe damage to the cable's sheath and internal structure, impacting its service life and reliability, and even potentially causing safety incidents. To improve the durability and safety of cables, the use of protective sheaths is crucial. While traditional cable protective sheaths can provide a certain degree of physical protection for cables, their complex installation process and low structural stability make them susceptible to cracking or failure due to external forces. Utility Model Content

[0005] Preferably, the inner rubber sleeve comprises a male half sleeve and a female half sleeve, and the wedge-shaped structure comprises a wedge block and a wedge groove. The wedge block is provided at the end of the male half sleeve, and the wedge groove is provided at the end of the female half sleeve. The male and female half sleeves cooperate with each other through the wedge block and the wedge groove. Here, when installing two sets of inner rubber sleeves, not only is positioning convenient, but after installation, the two sets of inner rubber sleeves are locked together by the wedge structure to prevent radial movement, thereby improving the stability of the structure.

[0006] Preferably, the outer wall surface of the inner rubber sleeve is provided with a limit groove, and the inner wall surface of the outer rubber sleeve is provided with a limit strip, which is slidably connected within the limit groove. Here, the outer rubber sleeve can be firmly fixed during assembly, effectively preventing the cable protective sleeve from slipping or loosening during use, and further enhancing the stability of the protective sleeve.

[0007] Preferably, the number of the limiting grooves is four, and the four groups of limiting grooves are distributed circumferentially on the surface of the inner rubber sleeve. Here, the four groups of limiting grooves can provide multiple limiting points, so that the protective sleeve is evenly stressed on the cable, further preventing the protective sleeve from shifting after assembly, and improving its stability and firmness.

[0008] Preferably, the outer and inner rubber sleeves are provided with holes, screws are inserted into the holes, and nuts are fixedly mounted on the inner surface of the inner rubber sleeve, with the screws and nuts being threadedly connected. This further strengthens the tight connection between the layers, prevents displacement or separation between the layers, and improves the overall firmness of the protective sleeve.

[0009] Preferably, the nut is embedded in the inner rubber sleeve. Because the nut is located on the inner surface of the inner rubber sleeve, it is inconvenient to fix the nut when installing the screw, so the nut is embedded in the inner rubber sleeve, which is more conducive to the installation of the screw.

[0010] Preferably, the outer rubber sleeve and the inner rubber sleeve are both provided with heat dissipation holes, which can more easily dissipate the heat generated by the cable operation.

The precise fit improves the installation convenience and overall stability, and avoids the influence of loose protective sleeve on the cable protection effect. The limit strip of the outer rubber sleeve is slidably connected with the limit groove on the inner rubber sleeve, so that the outer rubber sleeve can be firmly fixed during the assembly process, preventing slippage or loosening during long-term use, thereby further enhancing the stability and firmness of the protective sleeve.

[0013] 2. In the present invention, the surfaces of the outer rubber sleeve and the inner rubber sleeve are provided with perforations, and screws are inserted for fastening. The screws are connected with the nuts on the inner rubber sleeve to ensure the close connection between the layers of structure and avoid displacement or separation between the layers.

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example

[0024] See also Figure 1-4The utility model provides a technical solution: a cable protective sleeve with enhanced protection, comprising an outer rubber sleeve 1 and an inner rubber sleeve 3. The outer rubber sleeve 1 is attached to the outer surface of the inner rubber sleeve 3. The surface of the outer rubber sleeve 1 is provided with a connecting edge 7. The inside of the connecting edge 7 is fixedly connected with a fastener 8. The inner surface of the outer rubber sleeve 1 is provided with an upper semicircular hole 14. The outer surface of the inner rubber sleeve 3 is provided with a lower semicircular hole 13. The outer rubber sleeve 1 is formed by splicing two groups of symmetrical semicircular structures. The positions of the upper semicircular hole 14 and the lower semicircular hole 13 correspond one to one. The radius of the upper semicircular hole 14 and the lower semicircular hole 13 are consistent. The rubber sleeve 3 is composed of two symmetrical structures. The joint of the inner rubber sleeve 3 is equipped with a mating wedge structure. The inner rubber sleeve 3 comprises a male half 31 and a female half 32. The wedge structure comprises a wedge block 21 and a wedge groove. The wedge block 21 is provided at the end of the male half 31, and the wedge groove is provided at the end of the female half 32. The male and female halves 31 and 32 cooperate with each other through the wedge block 21 and the wedge groove. This ensures that during assembly, the two symmetrical male and female halves 31 and 32 can only slide axially, preventing radial sliding, improving assembly accuracy and reducing assembly difficulty. The inner rubber sleeve 3 is fixedly connected by two mutually perpendicular and staggered pins 5.

[0025] An upper semicircular hole 14 is formed on the inner surface of the outer rubber sleeve 1, and a lower semicircular hole 13 is formed on the outer surface of the inner rubber sleeve 3. The outer rubber sleeve 1 is composed of two groups of semicircles of the same size, and the inner rubber sleeve 3 is composed of two groups of semicircles of the same size. The positions of the upper semicircular holes 14 and the lower semicircular holes 13 correspond one to one, and the radius of the upper semicircular holes 14 and the lower semicircular holes 13 are consistent, which can make the cable protective sleeve easier to install during the cable installation process, especially when it is necessary to cover an existing cable. The semicircular fitting method can be used for quick assembly. The cooperation between the upper semicircular hole 14 and the lower semicircular hole 13 ensures that the inner and outer layers fit tightly, improves the overall stability of the protective sleeve, and prevents the protective sleeve from loosening and affecting the protective effect.

[0026] A limiting groove 12 is provided on the outer wall surface of the inner rubber sleeve 3, and a limiting strip 4 is provided on the inner wall surface of the outer rubber sleeve 1. The limiting strip 4 is slidably connected inside the limiting groove 12, so that the outer rubber sleeve 1 can be firmly fixed during the assembly process, effectively preventing the cable protective sleeve from slipping or loosening during use, and further enhancing the stability of the protective sleeve.

[0027] There are four groups of limiting grooves 12, and the four groups of limiting grooves 12 are distributed circumferentially on the surface of the inner rubber sleeve 3. The four groups of limiting grooves 12 can provide multiple limiting points, so that the protective sleeve is evenly stressed on the cable, further preventing the protective sleeve from being offset after assembly, and improving its stability and firmness.

[0028] The outer and inner rubber sleeves 1 and 3 are provided with perforations 6, each with a screw 10 inserted therein. A nut 9 is fixedly mounted on the inner surface of the inner rubber sleeve 3. The threaded connection between the screw 10 and the nut 9 further strengthens the tight connection between the various layers, prevents displacement or separation between the layers, and enhances the overall robustness of the protective sleeve. To facilitate the installation of the screw 10, the nut 9 is embedded within the inner rubber sleeve 3. Because the nut 9 is located on the inner surface of the inner rubber sleeve 3, it is difficult to secure the nut 9 during installation. Therefore, the nut 9 is embedded within the inner rubber sleeve 3 to facilitate the installation of the screw 10.

[0029] Working principle: When installing two sets of inner rubber sleeves, the wedge structure not only facilitates positioning, but also locks the two sets of inner rubber sleeves into each other through the wedge structure after installation to prevent radial movement and improve the stability of the structure. The upper semicircular hole 14 of the outer rubber sleeve 1 and the lower semicircular hole 13 of the inner rubber sleeve 3 ensure that the protective sleeve fits tightly on the cable, making the installation process simple and stable. Especially when covering existing cables, the precise matching of the upper and lower semicircular holes 13 ensures the tight combination between the inner and outer layers, avoiding protection failure caused by looseness. At the same time, the limiting strip 4 of the outer rubber sleeve 1 cooperates with the limiting groove 12 on the inner rubber sleeve 3 to ensure that the various parts of the protective sleeve remain fixed during installation through a sliding connection, preventing loosening or displacement during long-term use, thereby enhancing the overall stability and durability. In addition, the four groups of limiting grooves 12 are distributed circumferentially, so that the protective sleeve can evenly withstand forces from different directions during use, further preventing position displacement, and ensuring stable protection in various complex installation environments. The perforation 6 design of the protective sleeve further enhances its firmness. Through the threaded connection of the screw 10 and the nut 9, the various layers of structure are tightly combined, and it is convenient for later maintenance and disassembly. The user can achieve flexible maintenance by adjusting the tightness of the screw 10, which also makes maintenance more convenient.
