Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to an anti-vibration fiber optic trough for fiber optic cable installation. Background Technology

[0002] With the continuous development of information technology, the total amount of information data is experiencing explosive growth. In the era of big data, cloud computing, and the Internet of Things, the emergence of massive amounts of data directly poses uninterrupted service and communication line uninterrupted requirements for the normal operation of data center businesses. In order to ensure the normal transmission of fiber optic networks and the ability to ensure communication lines remain uninterrupted in the event of major natural disasters, it is required that the plastic fiber optic cable tray system used in data center computer rooms must have seismic resistance. Furthermore, a sealed design is required to protect the fiber optic module cables within the plastic fiber optic cable tray system.

[0003] Chinese patent document CN220730495U discloses a seismic-resistant enclosed plastic optical fiber channel, including a bridge and a U-shaped channel for placing optical fibers disposed within the bridge. The bridge is a U-shaped frame, including two sets of parallel keel groups, which are connected by several crossbars. The bottom wall of the U-shaped channel is fixed to the crossbars; the side wall of the U-shaped channel is fixed to the uprights; a top cover plate is provided on the top of the U-shaped frame, and side cover plates are provided at both ends of the U-shaped frame, thereby enclosing the bridge. This application achieves the enclosure of the bridge by providing top and side cover plates on the top and sides of the bridge, respectively, avoiding the exposure of the optical fibers installed in the U-shaped channel and protecting the optical fibers; by providing sliding grooves one and two to cooperate and fix with the uprights and crossbars, the U-shaped channel and the bridge are installed as an integral structure, and the installation method is simple.

[0004] Although existing fiber optic troughs have shock-resistant features, their shock resistance is poor, and the sealing method between the top cover plate and the trough is also ineffective. Summary of the Invention

[0005] To overcome the shortcomings of the existing technology, this utility model provides an anti-vibration fiber optic trough for fiber optic cable installation. Although existing fiber optic troughs have anti-vibration function, their anti-vibration effect is poor, and the sealing method between the top cover plate and the trough is also inadequate, resulting in poor sealing performance.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a shock-resistant fiber optic cable tray for fiber optic cable installation, comprising:

[0007] The U-shaped channel has two screw mounting pieces fixedly installed on both sides, and three semi-circular strips fixedly installed on both sides of the top opening of the U-shaped channel.

[0008] The n-shaped top cover is installed on the outside of the top opening of the U-shaped channel. Three semi-circular grooves are opened on the inner walls of both sides of the n-shaped top cover, and the three semi-circular grooves are adapted to the corresponding semi-circular strips.

[0009] Two sealing structures are adapted to the two ends of the U-shaped channel;

[0010] Multiple shock-absorbing structures are installed on the bottom inner wall of the U-shaped channel. The top of the multiple shock-absorbing structures is fixedly installed with the same shock-absorbing plate, and the top of the shock-absorbing plate is fixedly installed with multiple clips.

[0011] Preferably, the top of the card strip has multiple sets of card slots, which are arc-shaped structures, for fixing the optical fiber.

[0012] Preferably, the damping structure includes a mounting plate, which is fixedly installed on the bottom inner wall of the U-shaped channel. A titanium alloy disc spring is fixedly installed on the top of the mounting plate, and a silicone rubber damping column is fixedly installed on the top of the titanium alloy disc spring. The silicone rubber damping column is fixedly installed to the bottom of the damping plate, and a damping groove is formed at the bottom of the silicone rubber damping column. The titanium alloy disc spring is fixedly installed to the inner wall of the damping groove; this structure is used to provide shock absorption for the damping plate.

[0013] Preferably, the sealing structure includes a mounting plate, a sealing head is fixedly mounted on the inner side of the mounting plate, the inner side of the sealing head is provided with an arc-shaped surface, the sealing head cooperates with the end of the U-shaped channel, finger grooves are provided on both sides of the mounting plate, and multiple through holes are provided on the sealing head, and sealing rings are provided on the inner walls of the multiple through holes.

[0014] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0015] 1. The fiber optic cable passes through the through hole and extends into the interior of the U-shaped channel. The fiber optic cable is inserted into the slot for quick fixation. The n-shaped top cover is inserted into the outside of the U-shaped channel. The three semi-circular strips cooperate with the three semi-circular slots. The three semi-circular strips are made of rubber to improve the sealing effect between the n-shaped top cover and the U-shaped channel.

[0016] 2. Insert two sealing structures into both ends of the two U-shaped channels. The titanium alloy disc springs and silicone rubber damping columns provide double support for the damping plate, thus playing a supporting and earthquake-resistant role.

[0017] The device uses a titanium alloy disc spring and a silicone rubber damping column to form a composite shock absorption system, which improves the seismic resistance. The interlocking fit between the rubber semicircular strip and the semicircular groove achieves a three-point elastic seal, improving the installation and sealing effect. Attached Figure Description
