Problems solved by technology

In the prior art, when laying underground wires and cables, especially when laying them in curved pipes, when passing the wires and cables from the outer end of the protective sleeve to the other end after bending, some of the ends of the wires and cables Simple bandaging treatment may easily cause damage to the protective sleeve, which may lead to potential safety hazards during use. Some threading methods with guiding structures have complex structures, and poor guiding accuracy and low work efficiency also increase the number of operators. labor intensity

Embodiment 1

[0034] like figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a wire and cable bending protection tube device includes a cable holding block 1, the rear end of the cable holding block 1 is provided with an axial hole, and the cable holding block 1 passes through the axial hole and the outer protective layer 4 of the wire and cable To prevent the wire core 3 of the wire and cable from being damaged by external forces such as extrusion, the front end of the cable holding block 1 is connected to the head guide structure.

[0035] A protective layer 2 is provided between the inner surface of the axial hole and the outer protective layer 4 to protect the cables and increase friction.

[0036] The head guide structure includes a spherical or ellipsoidal guide head 12, which is connected to the front end of the cable holding block through an elastic structure with predetermined rigidity. The connection through the elastic structure can increase the bending deform...

Embodiment 2

[0042] like Image 6 As shown, the front end of the connecting body 10 is provided with a sphere 21, and the sphere 21 cooperates with the spherical inner cavity hole 1 of the guide head 12. The front end of the connecting body 8 is connected to the ball 21 through a detachable screw thread.

[0043] The rear end of the position-limiting boss one 9 is connected with the auxiliary connecting block one 23, and the spring connecting block one 22 is fixedly connected at the front end of the spring, and the auxiliary connecting block one 23 and the spring connecting block one 22 are connected by screw threads.

[0044] The front part of the cable holding block 1 is provided with a hemispherical inner cavity 15, and the middle of the rear part of the hemispherical inner cavity 15 is provided with an inner cavity opening, and the rear end of the spring is connected with the second movable connector, and the second movable connector includes Connecting body two 5; the rear end of con...

Embodiment 3

[0047] like Figure 7 As shown, on the basis of embodiment 1 or embodiment 2, a hemispherical body 24 is provided at the rear end of the connecting body two 5, and the hemispherical body 24 cooperates with the hemispherical inner cavity 15, and the hemispherical body 24 and the connecting body two 5 The rear end is connected by threads. Through the cooperation of the hemispherical body 24 and the hemispherical inner cavity 15, the hemispherical body 24 and the hemispherical inner cavity 15 can relatively swing and rotate, which increases the guiding effect of the guide head. The friction resistance of the head becomes smaller, and it can move to the side of the protective sleeve to pass through the bending position smoothly, ensuring that the wires and cables pass through the protective sleeve smoothly. The position of relative movement, or the position of swing and rotation between the hemispherical body 24 and the hemispherical inner cavity 15 can be limited by the limiting...

Abstract

The invention discloses an electric wire or cable threading bended protective pipe device. The electric wire or cable threading bended protective pipe device comprises a cable clamping block, the rear end of the cable clamping block is provided with an axial hole, the cable clamping block is connected with the outer protective layer of an electric wire or cable, and the front end of the cable clamping block is connected with a head guide structure. The electric wire or cable threading bended protective pipe device is accurate in threading guidance, improves the operation accuracy and sensitivity as well as the wire or cable threading efficiency and accuracy for users and reduces the working intensity.

Description

technical field [0001] The invention relates to the technical field of protection facilities for wires and cables through pipes, in particular to a device for wires and cables through curved pipes. Background technique [0002] Wires and cables are widely used. Because the safety and reliability of wires and cables need to be considered, it is often necessary to use protective sleeves for protection during wiring layout. Some are used in underground environments, and cables need to be bent so that It is suitable for safe and reliable routing of curved underground pipelines, and at the same time avoids potential safety hazards caused by damage to wires and cables during wiring construction, and meets the requirements of safety standards such as waterproof and fire prevention. In the prior art, when laying underground wires and cables, especially when laying them in a curved pipeline, when the wires and cables are passed from the outer end of the protective sleeve to the other...
