Problems solved by technology
When laying optical cables in existing railway tunnels, if the channels are used for laying, the cover needs to be lifted, the workload is heavy, and the construction progress is slow; some tunnel cable channels are not reserved or are insufficiently reserved, resulting in laying that cannot meet the isolation requirements , so it is necessary to install the optical cable on the wall. Most of the existing technologies are single-cable fixing devices or "L" type multi-cable fixing devices, which have the following defects when used:
Therefore, the current cable fixing device has the problems of complex structure and cumbersome operation.

Abstract
The purpose of the invention is to provide a wall-mounted optical cable fixing device and a manufacturing method thereof which are simple in structure and convenient in usage, and can save space and rapidly dismount cables. The device includes a pedestal; the pedestal is provided with multiple fixing holes for bolts to pass through and multiple casing pipe grooves; one sides of the casing pipe grooves have openings; the casing pipe grooves are in slipping arrangement with casing pipes; the parts, at the opening, of the casing pipe grooves are in slipping arrangement with cable-fixing slide blocks which can link with the casing pipes; the pedestal is provided with buckling structures which can limit the cable-fixing slide blocks; each casing pipe includes two same casing pipe assemblies; the two ends of each casing pipe assembly extend outward in a radial direction to form limit flanges; and one sides of the cable-fixing slide blocks are provided with arc-shaped surfaces fitting with the outer walls of the casing pipe assemblies.
Description
technical field [0001] The invention relates to a wall-mounted optical cable fixing device and a manufacturing method thereof. Background technique [0002] In recent years, with the extensive adoption of optical communication technology, the proportion of optical cables in communication transmission systems is increasing. The optical fiber communication network with the railway company as the general hub is playing an active role in railway transportation. When laying optical cables in existing railway tunnels, if the channels are used for laying, the cover needs to be lifted, the workload is heavy, and the construction progress is slow; some tunnel cable channels are not reserved or are insufficiently reserved, resulting in laying that cannot meet the isolation requirements , so it is necessary to install the optical cable on the wall. Most of the existing technologies are single-cable fixing devices or "L" type multi-cable fixing devices, which have the following defects...
