[0002] Optical fiber, abbreviated as optical fiber, is an optical conduction tool that achieves total internal reflection of light in a fiber made of glass or plastic.

[0003] The prior art patent (Patent No.: 202022631973.9, Patent Name: An Optical Fiber Communication Cable Breakpoint Maintenance and Fixing Device) can achieve clamping and fixing of the cable by setting a first arc-shaped plate and a second arc-shaped plate, facilitating the fusion splicing of the cable breakpoint.

[0004] The above-mentioned technical patent has the following defects: The cable itself has gravity, and under the action of gravity, there is a pulling force on the cable. When fixing the cable, it is necessary to ensure that the cable breakpoints are in contact with each other. Therefore, the staff needs to continuously pull the cable to ensure that the cable breakpoints are in contact with each other, increasing the number of hands required for cable fixing, thus wasting manpower. Therefore, an optical cable maintenance cable fixing device is proposed to solve the above problems. Summary of the Utility Model

Detailed Embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Referring to Figures 1-5 , a fixing device for optical cable maintenance cables, including a base 1. A pair of relatively arranged fixing rings 2 are fixedly connected to the top end of the base 1. A plurality of mounting frames 5 distributed in a circular pattern are fixedly connected to the inner wall of the fixing ring 2. A rotating shaft 11 is rotatably connected to the inner wall of the mounting frame 5. The rotating shaft 11 penetrates through the mounting frame 5. One end of the rotating shaft 11 is fixedly connected to a circular rotating block 9, and the other end of the rotating shaft 11 is fixedly connected to a clamping plate 3. A rotating ring 4 is sleeved outside the circular rotating block 9. Connecting rings 6 are fixedly connected to both side surfaces of the rotating ring 4.

[0022] It should be noted that: when the cable passes through the fixing ring 2 and is pulled due to its own gravity, the cable will drive the rotating ring 4 to rotate under the action of friction. The rotating ring 4 drives the fixed helical gear 8 to rotate. The fixed helical gear 8 drives the circular rotating block 9 to rotate through the telescopic helical gear 12. The circular rotating block 9 drives the clamping plate 3 to rotate through the rotating shaft 11, realizing the clamping function of the cable, thereby playing a limiting role on the cable, so that it is not necessary for the staff to continuously pull the cable, improving the fixing efficiency of the cable.

[0023] A torsion spring 10 is arranged on the surface of the rotating shaft 11, and anti-slip patterns are arranged on the clamping surface of the clamping plate 3.

[0024] It is worth noting that: the setting of the torsion spring 10 prevents the rotating ring 4 from driving the circular rotating block 9 to rotate when the cable passes through the fixing ring 2. The setting of the anti-slip patterns can enhance the friction between the clamping plate 3 and the cable.

[0025] A telescopic groove 901 is formed on the surface of the circular rotating block 9. A telescopic helical gear 12 is slidably connected inside the telescopic groove 901. A return spring 13 is fixedly connected between the telescopic helical gear 12 and the inner wall of the telescopic groove 901.

[0026] It should be noted that: referring to Figure 2 , when the fixed helical gear 8 rotates counterclockwise, it will squeeze the inclined surface of the telescopic helical gear 12, causing the telescopic helical gear 12 to retract inside the telescopic groove 901. When the fixed helical gear 8 rotates clockwise, the fixed helical gear 8 will drive the telescopic helical gear 12 to rotate, thereby driving the circular rotating block to rotate. The circular rotating block drives the clamping plate 3 to rotate through the rotating shaft 11, realizing the clamping function of the cable.

[0027] The inner wall of the rotating ring 4 is fixedly connected with a plurality of fixed helical teeth 8 arranged in a circle. Annular chutes are formed on both side surfaces of the rotating ring 4. A sliding ring 7 which is slidably connected with the annular chute is fixedly connected to one side surface of the adapter ring 6.

[0028] It should be noted that: the annular chute cooperates with the adapter ring 6, so that the adapter ring 6 can be rotatably connected with the circular rotating block 9, and further the rotating ring 4 can be rotatably connected with the circular rotating block 9.

[0029] When the present utility model is in use, when the cable passes through the fixed ring 2, the rotating ring 4 drives the fixed helical teeth 8 to rotate counterclockwise. The fixed helical teeth 8 will squeeze the inclined surface of the telescopic helical teeth 12, so that the telescopic helical teeth 12 retract into the inner side of the telescopic groove 901. At the same time, with the cooperation of the torsion spring 10, the circular rotating block 9 is prevented from rotating;

[0030] After the cable passes through the fixed ring 2 and due to its own gravity, when the cable is pulled, under the action of friction, the cable will drive the rotating ring 4 to rotate clockwise. The rotating ring 4 drives the fixed helical teeth 8 to rotate. The fixed helical teeth 8 drive the circular rotating block 9 to rotate through the telescopic helical teeth 12. The circular rotating block 9 drives the clamping plate 3 to rotate through the rotating shaft 11, so as to realize the clamping function of the cable, and further play a limiting role on the cable, so that it is not necessary for the staff to continuously pull the cable, reducing manpower while improving the fixing efficiency of the cable.

[0031] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes an equivalent replacement or change, and should be covered by the protection scope of the present utility model.
