Description

Technical Field

[0001] This utility model relates to the field of optical cable fixing technology, specifically to an optical cable fixing device for optical fiber distribution. Background Technology

[0002] Optical cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers placed in a protective sheath as the transmission medium and can be used individually or in groups. Optical cables are mainly composed of optical fibers (glass filaments as thin as a hair), plastic protective sheaths, and plastic outer jackets. Optical cables do not contain metals such as gold, silver, copper, or aluminum and generally have no recycling value. An optical cable is a communication line that uses a certain number of optical fibers arranged in a certain way to form a cable core, which is covered with a sheath, and some also have an outer protective layer, to realize the transmission of optical signals.

[0003] In the construction of optical fiber communication networks, the fixing and wiring of optical cables are key links to ensure stable signal transmission. Traditional optical cable fixing devices mostly use rigid clamps, which have the following problems: the optical cable lacks buffering capacity after fixing, and it is prone to breakage due to stress concentration when dragged by external forces. Therefore, there is an urgent need for an optical cable fixing device for optical fiber distribution. Utility Model Content

[0004] The purpose of this invention is to provide an optical cable fixing device for optical fiber distribution, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an optical cable fixing device for optical fiber distribution, comprising a fixing mechanism for fixing the optical cable, wherein an adjustment mechanism is provided on the back of the fixing mechanism;

[0006] The fixing mechanism includes a fixing plate. The front of the fixing plate has multiple first sliding grooves. Each first sliding groove is fixedly connected to a limit rod. Each limit rod has two first sliders slidably disposed on its surface. The front of each pair of first sliders is fixedly connected to the same fixing sleeve. Each fixing sleeve has a threaded hole on its front. Each threaded hole is threadedly connected to a first screw. The back of each pair of first screws extends into the fixing sleeve and is rotatably connected to the same pressure plate. Each limit rod has two springs sleeved on its surface. Each first screw has a first handwheel fixedly connected to its front.

[0007] Preferably, each of the first grooves is convex, and each of the first sliders is slidably disposed within the first groove.

[0008] Preferably, the ends of each pair of springs that are close to each other are fixedly connected to the first slider, and the ends of each pair of springs that are far apart from each other are fixedly connected to the side wall of the first slide groove.

[0009] Preferably, each pressure plate has an upper rubber pad on its inner side, and each fixing sleeve has a rubber ring fixedly connected inside.

[0010] Preferably, the adjustment mechanism includes a mounting plate, a second groove is provided on the front side of the mounting plate, a second screw is rotatably connected inside the second groove, a second slider is threadedly connected to the surface of the second screw, the top of the second screw passes through the mounting plate and extends to its outside, and a second handwheel is fixedly connected to the top of the second screw.

[0011] Preferably, the second slider is slidably disposed within the second groove, and the front side of the second slider is fixedly connected to the fixing plate.

[0012] Preferably, two mounting ears are fixedly connected to each end of the mounting plate.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] First, in this utility model, when it is necessary to fix the optical cable, the optical cable is first passed through the fixing sleeve. Then, by rotating the first handwheel, the first screw is driven to rotate. Since the first screw is threadedly connected to the fixing sleeve, rotating the first screw will cause it to move axially, thereby pushing the pressure plate to press the optical cable. At the same time, the presence of the spring gives the fixing sleeve a certain buffering capacity. When the optical cable is suddenly subjected to force and dragged, it can play a certain buffering role in conjunction with the rubber buffer layer, avoiding the optical cable fixed in the fixing sleeve from breaking. It can also be used to fix optical cables of different thicknesses.

[0015] Secondly, by rotating the second handwheel, the second screw can be rotated, thereby driving the second slider to move horizontally in the second groove. Since the second slider is fixedly connected to the fixed plate, the fixed plate will also move accordingly, thereby realizing the horizontal position adjustment of the fixing mechanism.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides the following technical solution:

[0023] Example 1

[0024] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 A fiber optic cable fixing device for fiber optic distribution includes a fixing mechanism for fixing the fiber optic cable, and an adjustment mechanism is provided on the back of the fixing mechanism.

[0025] The fixing mechanism includes a fixing plate 11. The front of the fixing plate 11 has multiple first sliding grooves. Each first sliding groove is fixedly connected to a limit rod 12. Each limit rod 12 has two first sliders slidably disposed on its surface. The front of each pair of first sliders 13 is fixedly connected to the same fixing sleeve 14. Each fixing sleeve 14 has a threaded hole on its front. Each threaded hole is threadedly connected to a first screw 15. The back of each pair of first screws 15 extends into the fixing sleeve 14 and is rotatably connected to the same pressure plate 16. Each limit rod 12 has two springs 17 sleeved on its surface. Each first screw 15 has a first handwheel fixedly connected to its front.

[0026] Each first groove is convex in shape, and each first slider 13 is slidably disposed within the first groove.

[0027] The ends of each pair of springs 17 that are close to each other are fixedly connected to the first slider 13, and the ends of each pair of springs 17 that are far apart from each other are fixedly connected to the side wall of the first slide groove.

[0028] Each pressure plate 16 has an upper rubber pad on its inner side, and each fixing sleeve 14 has a rubber ring fixedly connected inside.

[0029] Through the above technical solution, the fixing plate 11 is the foundation of the entire fixing mechanism. Multiple first sliding grooves are formed on its front side. Each first sliding groove is fixedly connected to a limiting rod 12, which guides and restricts the movement direction of the first slider 13. Two first sliders 13 are slidably disposed on the surface of each limiting rod 12, allowing the first sliders 13 to slide freely within the first sliding groove along the direction of the limiting rod 12. The same fixing sleeve 14 is fixedly connected to the front side of every two first sliders 13. The fixing sleeve is used to directly wrap and fix the optical cable. Each fixing sleeve 14 has a threaded hole on its front side, with a first screw 15 threadedly connected internally. The back sides of every two first screws 15 extend into the fixing sleeve 14 and are rotatably connected to the same pressure plate 16. By rotating the first screws 15, the position of the pressure plate 16 can be adjusted, thereby pressing or releasing the optical cable. Each limiting rod 12... Two springs 17 are fitted on the surface of each of the two first sliders 13, which are located on the outside of the two first sliders 13 respectively. The springs 17 provide pre-tightening force to the first sliders 13, so that the fixing sleeve 14 maintains a certain tension when no external force is applied. Each first screw 15 is fixedly connected to the front of the first handwheel, which is convenient for the operator to rotate the first screw 15. When it is necessary to fix the optical cable, the optical cable is first passed through the fixing sleeve 14. Then, by rotating the first handwheel, the first screw 15 is driven to rotate. Since the first screw 15 is threadedly connected to the fixing sleeve 14, rotating the first screw 15 will cause it to move axially, thereby pushing the pressure plate 16 to press the optical cable. At the same time, the presence of the springs 17 gives the fixing sleeve 14 a certain buffering capacity. When the optical cable is suddenly subjected to force and dragged, it can play a certain buffering role and prevent the optical cable fixed in the fixing sleeve 14 from breaking. It can also be used to fix optical cables of different thicknesses.

[0030] Example 2

[0031] Please see Figure 1 , Figure 3 and Figure 4 Furthermore, based on Embodiment 1, the adjustment mechanism includes a mounting plate 21, a second sliding groove is provided on the front side of the mounting plate 21, a second screw 22 is rotatably connected inside the second sliding groove, a second slider 23 is threadedly connected to the surface of the second screw 22, the top of the second screw 22 passes through the mounting plate 21 and extends to its outside, and a second handwheel is fixedly connected to the top of the second screw 22.

[0032] The second slider 23 is slidably disposed in the second groove, and the front side of the second slider 23 is fixedly connected to the fixing plate 11.

[0033] Two mounting ears 24 are fixedly connected to both ends of the mounting plate 21.

[0034] With the above technical solution, the mounting plate 21 serves as the base of the adjustment mechanism. A second slide groove is provided on its front side, and a second screw 22 is rotatably connected inside the second slide groove. A second slider 23 is threadedly connected to the surface of the second screw 22. The second slider 23 can slide freely in the second slide groove along the direction of the second screw 22. The top of the second screw 22 passes through the mounting plate 21 and extends to its outside. A second handwheel is fixedly connected to it, which facilitates the operator to rotate the second screw 22. Two mounting ears 24 are fixedly connected to both ends of the mounting plate 21, which are used to fix the entire device to the wall or other supporting structure. The front side of the second slider 23 of the adjustment mechanism is fixedly connected to the fixing plate 11 in Embodiment 1. Therefore, by rotating the second handwheel, the second screw 22 can be rotated, thereby driving the second slider 23 to move horizontally in the second slide groove. Since the second slider 23 is fixedly connected to the fixing plate 11, the fixing plate 11 will also move accordingly, thereby realizing the horizontal position adjustment of the fixing mechanism.

[0035] In actual operation, when this device is in use and it is necessary to fix the optical cable, firstly, the optical cable is passed through the fixing sleeve 14. Then, by rotating the first handwheel, the first screw 15 is driven to rotate. Since the first screw 15 is threadedly connected to the fixing sleeve 14, rotating the first screw 15 will cause it to move axially, thereby pushing the pressure plate 16 to press the optical cable. At the same time, the presence of the spring 17 gives the fixing sleeve 14 a certain buffering capacity. When the optical cable is suddenly subjected to force and dragged, it can play a certain buffering role and prevent the optical cable fixed in the fixing sleeve 14 from breaking. When it is necessary to adjust the position of the fixing mechanism, by rotating the second handwheel, the second screw 22 can be driven to rotate, thereby driving the second slider 23 to move horizontally in the second slide groove. Since the second slider 23 is fixedly connected to the fixing plate 11, the fixing plate 11 will also move accordingly, thereby realizing the horizontal position adjustment of the fixing mechanism.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
