Description

Technical Field

[0001] This utility model relates to the field of communication equipment technology, and in particular to an optical cable identification mechanism. Background Technology

[0002] In optical fiber communication systems, identification signs are usually installed at key nodes of the optical fiber to facilitate line maintenance and identification.

[0003] Chinese patent CN203397625U discloses an optical cable marking mechanism, including two semi-circular fixing rings connected by hinges, and a fixing plate locked by bolts. Although this structure solves the problem of complex installation of traditional signs, it still has significant drawbacks in actual operation and maintenance: each disassembly requires the use of tools to loosen and remove the bolts, making the operation cumbersome; tightening the bolts requires both hands, which is extremely inconvenient in restricted environments such as utility poles and pipe wells; and it increases maintenance costs for scenarios that require repeated disassembly and reassembly of signs (such as line renovation).

[0004] Therefore, the existing bolt hinge fixing method is difficult to meet the needs of efficient operation and maintenance of modern optical cable networks, and there is an urgent need to develop an identification mechanism that can be quickly installed and removed with one hand without tools. Utility Model Content

[0005] The purpose of this invention is to provide an optical cable marking mechanism that can be quickly installed and removed with one hand without tools.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an optical cable marking mechanism, including an upper fixed ring and a lower fixed ring, wherein an marking plate is fixedly mounted on the upper fixed ring, the right sides of the upper fixed ring and the lower fixed ring are rotatably connected by a hinge shaft, and an upper fixed plate and a lower fixed plate are respectively fixedly mounted on the left sides of the upper fixed ring and the lower fixed ring, and a locking mechanism is provided between the upper fixed plate and the lower fixed plate, wherein the locking mechanism includes an upper slot in the upper fixed plate, a lower slot in the lower fixed plate, a movable claw located in the upper slot, a fixed claw located in the lower slot, a spring that provides elasticity to make the movable claw engage with the fixed claw, and a control component that makes the movable claw disengage from the fixed claw.

[0007] By adopting the above technical solution, the movable claw can be engaged with the fixed claw by the spring, thus fixing the upper and lower fixed rings; the control component can disengage the movable claw from the fixed claw, realizing remote unlocking, without tools and supporting one-handed operation.

[0008] The fixed claw is further configured such that: the fixed claw includes engaging teeth and a guide slope formed on the engaging teeth; one end of the spring is fixedly connected to the movable claw, and the other end of the spring is fixedly connected to the inner wall of the upper slot; the deformation direction of the spring is perpendicular to the length direction of the movable claw; during the process of the movable claw engaging with the fixed claw, the movable claw first slides along the guide slope of the fixed claw, and then, under the action of the spring's restoring force, the movable claw finally engages with the engaging teeth of the fixed claw.

[0009] By adopting the above technical solution, the guide slope guides the movable jaw to accurately engage, and guides the movable jaw to engage with the engaging teeth. The vertically set spring provides efficient reset force to ensure reliable engagement of the movable jaw. When the upper / lower fixed ring is pressed with one hand, the movable jaw can slide along the guide slope of the fixed jaw to engage with the engaging teeth. The compressed spring provides reset force, and after reaching the engagement position, the spring automatically resets to achieve locking.

[0010] The further configuration is as follows: a guide assembly is provided between the movable claw and the upper slot, the spring is sleeved on the guide assembly, the guide assembly includes a sliding post and a sliding groove that forms a sliding fit with the sliding post, the sliding post is fixedly connected to the movable claw, and the sliding groove is fixedly connected to the inner wall of the upper slot.

[0011] By adopting the above technical solution, the cooperation between the sliding column and the sliding groove limits the movement trajectory of the movable claw, prevents the spring from deflecting, and improves the stability of the mechanism.

[0012] The control component is further configured as follows: the control component includes a control rope, a first hidden slide, a second hidden slide, and a rotating cap. The first hidden slide is located on the upper fixed ring, and the second hidden slide is located on the hinge shaft with both ends connected to the outside. One end of the first hidden slide is connected to the upper slot, and the other end of the first hidden slide is connected to the second hidden slide. The first end of the control rope is fixedly connected to the sliding column, and its second end passes through the first hidden slide and the second hidden slide in sequence before being fixedly connected to the rotating cap. The rotating cap is threadedly connected to one end of the hinge shaft. By rotating the rotating cap, the control rope can be pulled, thereby overcoming the spring force and pulling the movable claw away from the fixed claw.

[0013] By adopting the above technical solution, the concealed slide is integrated into the existing structure, improving the overall aesthetics; the rotating cap is remotely unlocked via rope transmission, avoiding direct operation of the lock in narrow spaces; the rotating cap is threadedly connected to one end of the hinge shaft.

[0014] Further, the outer surface of the rotating cap is provided with anti-slip texture.

[0015] By adopting the above technical solution, the friction is increased to facilitate hand-operated rotation and enhance the convenience of single-handed operation.

[0016] The upper fixing plate and the lower fixing plate are further configured such that a locking tooth groove is provided on the opposite side of each other, and the locking tooth groove of the upper fixing plate is adapted to the shape of the locking tooth groove of the lower fixing plate.

[0017] By adopting the above technical solution, the locking tooth groove is designed to prevent the fixing ring from accidentally loosening and to improve the clamping force; the locking tooth groove of the upper fixing plate is adapted to the shape of the locking tooth groove of the lower fixing plate, reducing the gap between the two and having a certain aesthetic effect.

[0018] A further feature is provided: a gap compensation element is provided between the two locking tooth grooves, and the gap compensation element is made of an elastic material.

[0019] By adopting the above technical solution and setting the gap compensation component, the internal structure of the moving and fixed jaws can be avoided from being directly seen, thus blocking the view and improving the overall aesthetics; the setting of attaching the gap compensation component to one of the locking tooth grooves makes the installation process simple.

[0020] Further configured such that each of the locking tooth grooves is wavy in shape.

[0021] By adopting the above technical solution, the wavy tooth surface greatly increases the contact friction, prevents the retaining ring from accidentally loosening, and improves the clamping force.

[0022] The gap compensation component is further configured such that it is attached to the locking tooth groove of the locking tooth groove, the gap compensation component is annular, and the gap compensation component has a central hole through which the movable claw and the fixed claw pass.

[0023] By adopting the above technical solution, the ring structure evenly distributes the pressure, and the central hole avoids the core components of the locking mechanism, thus achieving the non-interference between the compensation function and the locking function. Attached Figure Description
