Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of optical cable installation, and particularly relates to a fixing support for optical cable. BACKGROUND

[0002] For the laying and installation of optical cable, a wire clamp or a wire slot can be used for supporting the optical cable. For the laying of long-distance optical cable, the wire clamp is used in large quantity or the wire length is too long, which is not conducive to the laying of the optical cable by the staff, and is high in cost and low in efficiency. Especially for the laying of optical cable in a high area, the difficulty and efficiency are lower.

[0003] The wire clamp support is generally installed and fastened by screws and other fasteners. For installation on different installation surfaces, the fastening may be insufficient and difficult to operate, that is, if the installation surface is too hard, a hole is needed to be opened by a hole opening device, which is low in efficiency, and when the hole is too large, the fastening between the fastener and the hole is insufficient. Especially for fixing large-specification optical cable, the optical cable generates a reaction force on the wire clamp, thereby affecting the fastening and stability of the wire clamp.

[0004] At the same time, if the wire clamp is used to limit the position of the optical cable, the contact surface between the optical cable and the wire clamp is small, and the optical cable is straight in and straight out with the wire clamp, and the optical cable is prone to sliding compared with the wire clamp, which affects the smoothness and stability of the laying.
