Description

Technical Field

[0001] The utility model relates to the field of cable protection cases, and specifically relates to a lightweight and high-pressure-resistant cable protection shell. Background Technique

[0002] With the rapid progress of modern industry and technology, cables, as an indispensable infrastructure in key fields such as power transmission and communication connection, their safety and reliability have become the focus of the industry. In high-pressure and complex application environments, cables face more severe challenges, including but not limited to high-intensity pressure shocks, harsh climate conditions, and frequent installation and maintenance requirements.

[0003] When traditional cable protection shells face these challenges, they often expose significant limitations. First, their excessive weight not only increases the difficulty of transportation and installation but also may lead to additional cost burdens. Second, insufficient pressure resistance makes it difficult for traditional shells to effectively protect cables in high-pressure environments, increasing potential safety risks. In addition, inconvenient installation is also a common problem of traditional shells, affecting work efficiency and user experience. Content of the Utility Model

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0040] Please refer to Figures 1-4 , a lightweight and high-pressure-resistant cable protection shell of the present utility model includes the following components:

[0041] A protective housing, the protective housing includes an upper shell 1 and a lower shell 2;

[0042] Splicing edges 3 are respectively provided on the side edges of the upper shell 1 and the lower shell 2, and mounting holes 4 for fixed connection are provided on the splicing edges 3;

[0043] The upper shell 1 and the lower shell 2 are spliced together by the mating of the splicing edges 3, and fasteners are configured on the mounting holes 4;

[0044] Compressive layers 10 are provided on the outer surfaces of the upper shell 1 and the lower shell 2, and a number of compressive rings 6 are evenly distributed inside the compressive layers 10;

[0045] A number of compressive holes 7 are arranged around the compressive rings 6;

[0046] Anti-slip patterns 8 are provided on the inner surfaces of the upper shell 1 and the lower shell 2.

[0047] In the preferred solution of the above lightweight and high-pressure-resistant cable protection housing:

[0048] Lightweight and high-pressure-resistant design

[0049] Compressive layer 10 and compressive ring 6: Compressive layers 10 are provided on the outer surfaces of the upper shell 1 and the lower shell 2 of the cable protection housing. A number of compressive rings 6 are embedded inside this layer. The compressive holes 7 on the compressive rings 6 are designed as any one of a rhombus structure or an elliptical structure. The existence of these holes enables the compressive layer 10 to generate local deformation when subjected to external pressure, effectively dispersing and absorbing the pressure, thereby improving the high-pressure resistance performance of the entire protection housing.

[0050] Material selection: The upper shell 1 and the lower shell 2 are made of any one of aluminum alloy, titanium alloy or composite fiber material. These materials all have high specific strength and good corrosion resistance, and can achieve the lightweight goal while ensuring the structural strength.

[0051] Anti-slip design

[0052] Anti-slip patterns 8: Anti-slip patterns 8 with a spiral groove structure are provided on the inner surfaces of the upper shell 1 and the lower shell 2. This spiral design not only increases the contact area with the cable, but also effectively prevents the cable from sliding inside the housing through its unique shape, ensuring the stability and safety of the cable in a complex environment.

[0053] Modular splicing design

[0054] Splicing Groove 5 and Splicing Ring 9: Each upper shell 1 and lower shell 2 has a splicing groove 5 at one end and a splicing ring 9 at the other end. This design allows multiple protective shells to be spliced together to extend the protection length or accommodate cables of different sizes. Furthermore, the combination of the splicing groove 5 and the splicing ring 9 ensures the stability and sealing of the overall structure after splicing.

[0055] Installation and fastening

[0056] Threaded holes and fasteners: The mounting holes 4 on the splicing edge 3 are designed as threaded holes for use with fasteners such as bolts and nuts. This design simplifies the installation process, improves installation efficiency, and ensures a secure connection between the upper shell 1 and the lower shell 2.

[0057] This utility model describes a lightweight and high-pressure resistant cable protection shell, the working principle of which is mainly reflected in the following aspects:

[0058] Splicing and fastening of protective shell:

[0059] The protective shell is composed of an upper shell 1 and a lower shell 2, which are joined together by side joint edges 3.

[0060] The joint edge 3 is provided with mounting holes 4 for fixing the upper shell 1 and the lower shell 2. By disposing fasteners (such as bolts, nuts, etc.) in these mounting holes 4, a tight connection between the upper shell 1 and the lower shell 2 can be ensured to prevent loosening due to external pressure or vibration.

[0061] The reinforcing effect of the pressure-resistant layer 10:

[0062] The outer surfaces of the upper shell 1 and the lower shell 2 are both provided with a pressure-resistant layer 10, which is the key to protecting the high-pressure resistance of the shell.

[0063] Several anti-pressure rings 6 are evenly distributed inside the anti-pressure layer 10. These anti-pressure rings 6 are made of high-strength materials and can provide effective support and dispersion when subjected to external pressure.

[0064] A plurality of pressure-resistant holes 7 are arranged around the pressure-resistant ring 6. The design of these holes enables the pressure-resistant layer 10 to undergo local deformation when subjected to pressure, thereby absorbing and dispersing the pressure and avoiding the shell rupture caused by pressure concentration.

[0065] Improved stability of anti-slip groove 8:

[0066] The inner surfaces of the upper shell 1 and the lower shell 2 are provided with anti-slip grooves 8, which are generally in the form of spiral grooves.

[0067] The main function of the anti-slip pattern 8 is to increase the friction with the cable and prevent the cable from sliding or shifting within the housing. This is crucial for ensuring the stability and safety of the cable in complex environments.

[0068] Summary:

[0069] Through the splicing and fastening of the upper shell 1 and the lower shell 2, the strengthening effect of the pressure-resistant layer 10, and the improvement of the stability of the anti-slip pattern 8, the cable protection housing of the present utility model achieves the dual goals of lightweight and high pressure resistance. The splicing structure of the protection housing makes installation and disassembly convenient and fast; the presence of the pressure-resistant layer 10 significantly improves the pressure resistance of the housing; and the anti-slip pattern 8 ensures the stable position of the cable within the housing. Under the combined action of these designs, the cable protection housing has broad application prospects in the fields of electricity, communication, etc.
