Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling of optical fiber amplifiers, and more specifically, to an anti-falling device for optical fiber amplifiers. Background Art

[0002] In today's communications industry, fiber amplifiers are key devices for improving signal strength, and their stability and safety are of vital importance. In order to protect these precision devices from damage caused by falling or external impact, they are usually equipped with anti-fall devices. These anti-fall devices generally include anti-fall plates installed on the outside of the fiber amplifier, which are designed to absorb impact force and thus reduce the force directly acting on the device body. However, the anti-fall devices in the prior art generally have an obvious weakness: they are mostly connected to the fiber amplifier in a rigid manner.

[0003] Although the rigid connection is simple and reliable, it lacks the necessary elasticity and buffering capacity when subjected to large external impacts. This design causes the anti-drop plate to easily break or deform when subjected to strong impacts, thus losing its original protective function. Once the anti-drop plate is damaged, the fiber amplifier is exposed to the external environment without effective protection and is extremely susceptible to further damage. This situation not only increases the cost of repairing or replacing equipment, but also may cause temporary interruption of the communication system, affecting the stability and reliability of communication services. Summary of the invention

[0012] The utility model is further configured that a plurality of the lateral strips are provided with telescopic sleeves, the telescopic sleeves are slidably connected to the insertion rod, and the design of the telescopic sleeves ensures the telescopic continuity of the sleeves when they are released.

[0013] Compared with the prior art, the utility model provides an anti-fall device for an optical fiber amplifier, which has the following beneficial effects:

[0014] 1. The protection mechanism provides an efficient and reliable protection measure for the optical fiber amplifier. By installing the anti-drop plate on the insertion rod and using the return spring and the raised plate to act between the insertion rod and the fixed sleeve, an elastic connection method is achieved.

By the unlocking sleeve acting on the elastic sheet, the anti-fall plate and the amplifier body are quickly separated. This mechanism not only facilitates the rapid removal of the anti-fall plate for maintenance or replacement when necessary, but also ensures that the protective device can be quickly released in an emergency to deal with possible safety risks.
