Description

Technical Field

[0001] This utility model relates to the field of optical fiber processing, specifically to an optical fiber slot limiting clamp. Background Technology

[0002] In the installation and maintenance of fiber optic communication systems, fiber optic cabling is used to secure optical fibers in an orderly manner within fiber optic cabling slots to control their bending radius and prevent signal loss. Traditional fiber optic cabling slots typically employ V-groove or U-groove structures, using mechanical clips or bolts to fix the fibers. However, due to the tiny diameter and fragile nature of optical fibers, precise positioning of the fibers is required during the operation using a microscope to ensure accurate embedding and stability within the slot. In this scenario, the operator must adjust the fiber position with one hand while operating the fixing device with the other, simultaneously observing the fiber's status in real-time through a microscope to complete the fiber cabling operation.

[0003] In practical applications, traditional clamps (such as bolt plates) require one hand to hold the clamp and the other hand to tighten the screws, which can easily obstruct the view or cause the fiber to come into contact with the optical fiber in microscope operation scenarios, leading to inaccurate positioning. In addition, bolt adjustment requires multiple tightening, which is inefficient and makes it difficult to achieve quick assembly and disassembly. At the same time, traditional clips or clamps are large in size, which can easily interfere with other optical fibers or equipment in high-density cabling scenarios, affecting the compact layout of the fiber optic cable trays. Utility Model Content

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A fiber optic cable slot limiting clamp, characterized in that it comprises:

[0006] The support base has an anti-slip pad on its surface;

[0007] The limiting clamp includes a fixed seat on a support base, an operating part on the fixed seat, and a folded downward pressure rod on the surface of the operating part. The fixed seat has a support shaft on its surface. The operating part can drive the folded downward pressure rod to make vertical and rotational movements around the support shaft on the surface of the fixed seat.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the operating part includes a knob for one-handed operation by the operator, and an elastic limiting structure connecting the knob and the fixed base. Both the knob and the elastic limiting structure have openings that are adapted to the support shaft.

[0010] Furthermore, the elastic limiting structure includes a limiting post at the end of the knob and an elastic element on the surface of the limiting post. The fixed base has a movable groove for the limiting post to be inserted into. The elastic element is located inside the movable groove and can provide a force to the knob in the direction of the fixed base.

[0011] Furthermore, the end of the limiting post away from the knob is provided with a limiting protrusion, the movable groove is provided with a cavity for the limiting protrusion to move within it, and the elastic element is located between the limiting protrusion and the opening of the movable groove.

[0012] Furthermore, the folded pressure rod has an overall L-shaped structure, and the end of the folded pressure rod closest to the knob is parallel to the support shaft.

[0013] Furthermore, the surface of the folded pressure bar is provided with reinforcing ribs.

[0014] Furthermore, a fixed mounting structure is provided between the knob and the folded pressure rod, and the folded pressure rod can be mounted on the knob through the fixed mounting structure.

[0015] Furthermore, the fixed installation structure includes a fixing clip located at the end of the folded lower pressure rod, and a fixing screw located on the fixing clip. The rotating surface is provided with a protrusion adapted to the fixing clip, and the protruding surface is provided with a threaded hole adapted to the fixing screw.

[0016] Beneficial effects

[0017] Compared with existing technologies, this utility model, through its limiting clamp, allows the operator to simply pull up and rotate the knob with one hand to move the folded pressure rod onto the V-groove for fixation, freeing up the other hand to focus on fiber positioning. This significantly improves the efficiency and safety of operation under a microscope. At the same time, the L-shaped folded pressure rod is compact in size and can fit closely to the edge of the fiber optic channel, reducing space occupation. It is especially suitable for high-density fiber optic distribution frames or miniaturized communication equipment scenarios. The elastic deformation of the elastic element can adaptively adjust the clamping force on the V-groove, avoiding the risk of overpressure from rigid clamps. It also allows the fiber to undergo slight displacement buffering when subjected to external disturbances, reducing the probability of breakage. Attached Figure Description

[0031] Please see Figure 1-5 The present invention provides a fiber optic cable tray limiting clamp 2, which includes a support base 1 with an anti-slip pad on its surface, and a limiting clamp 2 capable of clamping the cable tray on the limiting clamp 2.

[0032] The limiting clamp 2 includes a fixed seat 21 on the support base 1, an operating part 22 on the fixed seat 21, and a folded downward pressure rod 23 on the surface of the operating part 22. The fixed seat 21 is provided with a support shaft 24. The operating part 22 can drive the folded downward pressure rod 23 to make a vertical and rotational motion around the support shaft 24 on the surface of the fixed seat 21.

[0033] The operating unit 22 includes a knob 221 for one-handed operation and an elastic limiting structure connecting the knob 221 and the fixed base 21. Both the knob and the elastic limiting structure have openings adapted to the support shaft 24. The elastic limiting structure includes a limiting post 222 at the end of the knob 221 and an elastic element 223 on the surface of the limiting post 222. The fixed base 21 has a movable groove for the insertion of the limiting post 222.

The end of the limiting post 222 away from the knob 221 has a limiting protrusion 224. The movable groove has a cavity for the limiting protrusion 224 to move inside it. The elastic element 223 is located between the limiting protrusion 224 and the opening of the movable groove.

[0034] With the help of the limiting clamp 2, the operator only needs to pull up and rotate the knob 221 with one hand to move the folded lower pressure rod 23 onto the V-groove to complete the fixation, freeing up the other hand to focus on fiber optic positioning, which significantly improves the efficiency and safety of operation under the microscope.

[0035] In some embodiments, the folded pressure rod 23 has an overall L-shaped structure. The folded pressure rod 23 is parallel to the support shaft 24 at the end away from the knob 221. Furthermore, to enhance the strength of the folded pressure rod 23, reinforcing ribs are provided on the surface of the folded pressure rod 23.

[0036] Since the folded pressure rod 23 is relatively thin, if it is accidentally bent and needs to be replaced, a fixing structure 3 is provided between the knob 221 and the folded pressure rod 23. The folded pressure rod 23 can be installed on the knob 221 through the fixing structure 3. The fixing structure 3 includes a fixing clip 31 at the end of the folded pressure rod 23 and a fixing screw 32 on the fixing clip 31. The knob surface is provided with a protrusion that matches the fixing clip 31, and the surface of the protrusion is provided with a threaded hole that matches the fixing screw 32.
