Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to an outdoor cable that can be quickly installed. Background Art

[0002] Wires and cables are usually made of several or several groups of conductors twisted together, similar to ropes. Each group of conductors is insulated from each other and are often twisted around a center wire. The entire outside is covered with a highly insulating covering layer. They are mostly used to transmit and distribute electrical energy or transmit electrical signals. The installation and use of cables is a common step in the modern construction industry, but sometimes the installation of cables is time-consuming and labor-intensive, the installation process is complicated, and the workload is large. The laying of cables, installation, and final completion often take a very long time, and the installation often requires the assistance of a large number of tools. Carrying and installation are very inconvenient, which has a certain impact on construction efficiency.

[0003] For example, the Chinese utility model patent with the announcement number CN202905252U discloses a cable, comprising at least one conductive core conductor, an insulating layer arranged outside the core conductor, an inner sheath arranged outside the insulating layer, an armor layer arranged outside the inner sheath, and an outer sheath arranged on the outermost layer, and a foaming layer is added between the core conductor and the insulating layer, with a simple structure, reasonable design, and strong compressive and tensile resistance;

[0004] The above solution has the following problems: when the cable needs to be installed, the outer sheath of the cable needs to be peeled off, and the exposed wires are connected to the connecting pieces by screws, which may easily lead to loose or damaged wires due to improper tightening; and the cable cannot be fixed after installation;

[0005] So we propose a quick-install outdoor cable to solve the above problems. Utility Model Content

[0010] By adopting the above technical solution, the cable connection can be fixed by the fixing tube after the cable connection is completed. The fixing tube can be fixed on the outer sheath of the cable by rotating the shaft and the fixing tube can be freely opened and closed on the outer sheath of the cable, thereby achieving the purpose of strengthening the connection between the cables.

[0011] As a preferred technical solution of the utility model, a connecting block is arranged on the top of the fixed tube opposite to the rotating shaft; the connecting block and the fixed tube are designed as an integral whole; the connecting block is composed of two rectangular blocks; a connecting hole is opened inside the connecting block.

[0012] By adopting the above technical solution, the clamping degree of the fixing tube connected to the connecting block can be controlled through the connecting block, thereby making the connection between the cables more precise.

[0013] As a preferred technical solution of the utility model, the connection hole passes through the connection block; a thread is arranged inside the connection hole; a rotating handle is arranged at one end of the connection block; the rotating handle is movably connected to the connection hole through a thread.

[0014] The above technical solution can facilitate the fixation between the connection blocks through the connection holes and the rotating handle.

[0015] As a preferred technical solution of the utility model, the connecting ring is of telescopic design; a buffer cavity is provided at the connecting portion of the connecting ring; and the buffer cavity is a rectangular cavity.

[0016] The above technical solution can prevent the cables from being too close together and causing damage to the outer sheath of the cables when they are installed and connected through the buffer cavity.

[0017] As a preferred technical solution of the utility model, a waterproof layer is arranged inside the cable outer sheath; the waterproof layer is an aluminum-plastic composite tape layer.

[0018] The adoption of the above technical solution can improve the safety performance of the cable outdoors through the waterproof layer.

[0019] As a preferred technical solution of the utility model, the fixing tube and the cable outer sheath are provided with sealing rings; the sealing rings are embedded in the cable outer sheath.

[0020] The above technical solution can make the connection between the fixing tube and the outer sheath of the cable tighter through the sealing ring.

The operation is simple, thereby achieving the purpose of quick cable installation.

[0023] 2. The utility model is provided with a fixing tube and a connecting block. After the cable is installed, the connecting block is tightened to shrink the fixing tube to reinforce the two sections of the cable, thereby achieving the purpose of making the connection between the cables tighter.
