Problems solved by technology

In the prior art, there is no cable support whose structure and function fully meet the construction requirements. The cable supports in the prior art are all simple steel structures (supports built with angle steel or channel steel), which are too simple and cannot To form a good fit and fixation with different basic structures, it is necessary to temporarily build or manufacture support structures for different basic structures and according to the actual site conditions. Therefore, there are large variables, and there are technical problems such as simple structure and ineffective use

Embodiment 1

[0066] see Figure 1 to Figure 6 shown;

[0067] The cable casing of the present invention comprises:

[0068] The casing body 1, the casing body 1 is a split structure, and the casing body 1 has a first casing 101, a second casing 102, and a steering pipe 103 connected to each other;

[0069] The first sleeve 101 extends along a first direction;

[0070] The second sleeve 102 extends along the second direction;

[0071] The steering tube 103 turns the cable 3 passing through the bushing body 1 from the first direction to the second direction;

[0072] The first sleeve 101 and the steering pipe 103, the second sleeve 102 and the steering pipe 103 are all fixed by clamps (not shown);

[0073] Both the first sleeve 101 and the second sleeve 102 are formed with two partially overlapping cable penetration holes, which are the first cable penetration hole 104 and the second cable penetration hole 105 respectively;

[0074] The inner diameter of the first cable passing hole 104...

Embodiment 2

[0100] see Figure 7 shown;

[0101] The bracket for cable laying disclosed by the present invention includes a bracket body 2 installed with an external infrastructure, and the bracket body 2 is fixedly connected with the above-mentioned cable sleeve.

[0102] Wherein, the bracket body 2 in this embodiment includes a column 203, a first mounting frame 201 formed at the upper end of the column 203, and a second mounting frame 202 formed at the lower end of the column 203;

[0103] The cable sleeve is fixedly connected to the first installation frame 201;

[0104] The bracket is rigidly connected to the external infrastructure through the first mounting frame 2021 and the second mounting frame 202 .

[0105] More preferably, both the first mounting frame 201 and the second mounting frame 202 have an L-shaped structure, and the inner side of the L-shaped structure of the first mounting frame 201 is formed as an installation space for a cable sleeve, and the bottom surface of t...

Abstract

The invention discloses a cable bushing and a cable laying support. The cable bushing comprises a bushing body, wherein the bushing body is provided with a first bushing part, a second bushing part and a steering tube which are connected with one another; two partially-overlapping cable penetration holes are formed in the first bushing part, two partially-overlapping cable penetration holes are formed in the second bushing part, and the two corresponding cable penetration holes are a first cable penetration hole and a second cable penetration hole; the inner diameter of each first cable penetration hole is greater than the inner diameter of each second cable penetration hole; a cable clamping component is arranged at the end, away from the steering tube, of the first bushing part in an adaptive mode; and a cable clamping component is arranged at the end, away from the steering tube, of the second bushing part in an adaptive mode. The cable bushing provided with the two kinds of cable penetration holes can conveniently adapt to installation of cables with different specifications; and in order to prevent a cable from moving, a filling body and the cable clamping components are designed to ensure that the cable cannot have radial displacement and axial displacement after penetration, therefore, the safety is higher, and the structure is more novel and reliable.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to a cable sleeve and a bracket for laying cables. Background technique [0002] Cables are a common power transmission medium for power supply equipment / power supply devices. Therefore, cables are the main components that determine whether power supply equipment can transmit power normally. For electric power construction, the construction of cables and the laying of cables are a crucial task. [0003] In the construction and laying of cables, especially when they are in contact with external buildings, in order to protect the cables, improve their use effects, and make them have a longer service life, sleeves are generally installed at the positions where the cables are easily damaged. The tube can protect the cable turning point, or other places that are easy to damage the cable. [0004] There are already a variety of casing structures in the prior art, such a...
