Description

Technical Field

[0001] The utility model relates to the technical field of cable protection equipment, in particular to a new type of cable link sheath. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires.

[0003] Since cables are widely used in multiple fields and are often buried underground for a long time, an external protective structure is required to protect the cable body to prevent damage.

[0004] The prior art has the following deficiencies: In the "new type of cable link sheath" with the publication number CN208190170U in the prior art, "cable sheath teeth and cable sheath slots are respectively provided at the head end and the tail end of the cable sheath. The cable sheath is mutually clamped and wrapped outside the cable through the cable sheath teeth and the cable sheath slots. Left and right tightening buckles are respectively provided on the left and right sides of the outer surface of the pipe joint I, left and right buckles are respectively provided on the left and right sides of the top of the pipe joint I, and a pipe joint inner hole I is provided inside the pipe joint I";

[0005] The above structure can be used after being fixed by clamping the sheath and the pipe joint, which reduces the replacement difficulty and eliminates potential safety hazards. However, this structure does not make improvements to the external protection structure when the cable is bent and laid. When the cable is bent and laid, the current external protection structure is often difficult to bend easily due to its relatively thick material, and no limit setting is made for the cable inside the protection structure. When water enters the protection structure, the cable at the bottom end of the protection structure is easily soaked by water. Summary of the Utility Model

[0006] In view of the deficiencies of the prior art, the utility model provides a new type of cable link sheath, which solves the problem of being inconvenient to bend during installation.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A new type of cable link sheath, comprising a protective sleeve, a cable, and a rubber sleeve. The cable is arranged inside the protective sleeve, and the rubber sleeve is arranged on the peripheral end face of the cable;

[0008] A swivel joint is further arranged at the end of the protective sleeve;

[0009] The swivel joint includes an extension connecting piece, a rotating shaft, and a limit bolt. The extension connecting piece is fixedly connected to the outer end surface of the swivel joint. The rotating shaft penetrates through the middle of the extension connecting piece from the outside and extends inward. The limit bolt is movably connected to the end of the rotating shaft near the middle of the swivel joint.

[0010] As a preferred technical solution of the present utility model, the protective sleeve further includes a connecting block and a limiting frame. The connecting block is fixedly connected to the inner end face of the end of the protective sleeve, and the limiting frame is fixedly connected to the inner surface of the protective sleeve.

[0011] As a preferred technical solution of the present utility model, the side of the limiting frame facing the center of the protective sleeve is a concave arc-shaped notch structure. There are several groups of the limiting frames, and they are arranged in an equidistant straight line in a structure with three in a ring, and its extending direction is determined according to the laying direction of the protective sleeve.

[0012] As a preferred technical solution of the present utility model, circular groove-shaped structures recessed inward are provided on the outer end faces of the connecting block and the extending connecting member.

[0013] As a preferred technical solution of the present utility model, the adapter is movably connected to the protective sleeve by a rotating shaft passing through the extending connecting member and the connecting block.

[0014] As a preferred technical solution of the present utility model, the maximum angle that the adapter can rotate through the connection of the rotating shaft is 70°, and chamfering treatments are performed on the inner end faces thereof.

[0015] As a preferred technical solution of the present utility model, a channel-shaped structure recessed inward is provided at the position where the outer end of the protective sleeve is connected to the adapter, and the size of the channel-shaped structure is larger than that of the extending connecting member.

[0016] Compared with the prior art, the present utility model provides a new cable link sheath, which has the following beneficial effects:

[0017] For this new cable link sheath, by setting the adapter, the connecting block, the limiting frame and the rotating shaft, when this structure is installed outside the cable, when the cable is laid in a straight line, the cable only needs to be placed in the middle of the limiting frames inside the protective sleeve. When there are bending angles in the cable laying route, the operator needs to connect the adapter to the end of the protective sleeve on one side of the turning position. The adapter is inserted around the connecting block through the extending connecting member. After keeping the upper and lower alignment, the rotating shaft penetrates through the connecting block and the extending connecting member from the upper and lower ends, and is fixed by a limiting bolt at one end penetrating the connecting block. At this time, the connecting block can rotate outside the protective sleeve through the rotating shaft and the limiting bolt, and carry the cable structure inside to complete the bending. Through the above process, this device can not only fix the cable in the middle to prevent water from accumulating at the bottom when water enters the inside of the protective sleeve and affecting the cable, but also can be bent more conveniently during installation.
