Embodiment 1

[0038] like Figure 1-3As shown, the present invention provides a technical solution: a cable, comprising an outer protective layer 1, a movable sleeve block 2 is arranged inside the outer protective layer 1, an inner protective installation block 3 is arranged inside the movable sleeve block 2, and an inner protective layer is provided. The inside of the mounting block 3 is evenly and fixedly connected with the conductive core 4, and the inside of the movable sleeve block 2 is evenly provided with a movable chute 5. The interior of the movable chute 5 is slidably connected with a damping slider 6, and the damping slider 6 is far away from the movable sliding block. One end of the groove 5 is fixedly connected with the inner protection mounting block 3 , the outer surface of the outer protection layer 1 is evenly and fixedly connected with the dragging and shoveling mechanism 7 , and the outer surface of the outer protection layer 1 is located between the dragging and shoveling...

Embodiment 2

[0042] like Figure 4-5 As shown, on the basis of the first embodiment, the present invention provides a technical solution: a cable, the dragging and shoveling mechanism 7 includes a contact pressing piece 71, one end of the contact pressing piece 71 is fixedly connected with the outer protective layer 1, The front and rear ends of the bottom of the pressing sheet 71 are symmetrically and fixedly connected with a shovel cone 72 .

[0043] The shovel cone 72 adopts a triangular pyramid structure, and the wide ends of the shovel cone 72 are fixed to each other correspondingly, and the top of the shovel cone 72 is provided with a material guide arc groove 73 . The impurities on the ground can be guided to both sides, and at the same time, the large impurities on the ground can be shoveled, so as to avoid the large impurities in contact with the surface of the cable when dragging.

Embodiment 3

[0045] like Figure 6-7 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a cable, the impact protection mechanism 8 includes a protective outer frame 81, the top of the protective outer frame 81 is provided with a movable port, and the protective outer frame 81 is provided with a movable port. A protective rubber ball 82 is rotatably connected to the inside of the frame 81 near the movable port, and one end of the protective rubber ball 82 extends to the outside of the protective outer frame 81 . An elastic touch ball 83 is fixedly connected to the inside of the protective outer frame 81 , and the elastic touch ball 83 is arranged at a middle position inside the protective rubber ball 82 .

[0046] The outer surface of the protective rubber ball 82 is evenly provided with a receiving inner groove 84 , and a resistance-increasing insertion rod 85 is penetrated and slidably connected to the interior of the receiving in...

Abstract

The invention discloses a cable which comprises an outer protective layer, a movable sleeve block is arranged in the outer protective layer, an inner protective mounting block is arranged in the movable sleeve block, conductive cores are evenly and fixedly connected in the inner protective mounting block, and movable sliding grooves are evenly formed in the periphery of the interior of the movablesleeve block. Damping sliding blocks are slidably connected into the movable sliding grooves correspondingly, the ends, away from the movable sliding grooves, of the damping sliding blocks are fixedly connected with the inner protection mounting blocks, dragging shoveling mechanisms are evenly and fixedly connected to the outer surface of the outer protection layer, and impact protection mechanisms are evenly and fixedly connected to the positions, located between the dragging shoveling mechanisms, of the outer surface of the outer protection layer. And a pressure dispersion mechanism is fixedly connected to the position between the outer protective layer and the movable sleeve block. The invention relates to the technical field of cables. According to the cable, mechanical impact force is converted into air pressure, the air pressure is uniformly applied to the outer surface of the cable, local impact is dispersed, and impact damage is reduced to the minimum.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable. Background technique [0002] A cable is a power or signal transmission device, usually composed of several or groups of wires. [0003] For example, a cable with the Chinese Invention Publication No.: CN105336412A, includes a plurality of insulated wire cores, the insulated wire cores are twisted into a cable, each insulated wire core includes a conductor and an insulating layer, the outer portion of the cable is An aluminum sleeve is extruded on the surface, and the twisting pitch of the insulated wire core is the same as that of the aluminum sleeve. By directly extruding an aluminum sleeve on the outside of the cable, on the one hand, the consumption of filling materials is reduced, on the other hand, the outer diameter of the aluminum sleeve itself is reduced, and the consumables are less. The contact between the sleeve and the cable core is changed by a linear arc ...
