Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber boxes, and particularly relates to an optical fiber anti-slip coil box for mining. Background Art

[0002] The optical fiber coiling box for mining is mainly used for fixing the optical cable terminal in coal mines, fusing the optical cable with the pigtail, and storing and protecting the remaining fiber. The optical fiber coiling box for mining is mainly made of high-quality metal materials, has high mechanical strength, and is treated by electrostatic spraying. It is not only sturdy and durable, but also beautiful in appearance. The optical fiber receiving tray in the box is very convenient for fixing the heat shrink tube, coiling the optical fiber, expanding the capacity and maintaining it. It is suitable for dangerous places in coal mines with gas and coal dust explosions. It can be used for direct communication of underground optical cables and large-capacity branched fiber coiling, and it can protect the optical cable joints.

[0003] In the prior art, when placing a number of optical fiber reels in an optical fiber receiving tray, the optical fibers are fixed on an L-shaped fiber coiling rack. However, during the fiber coiling process, a few optical fibers often fall off the fiber coiling rack, and the optical fibers need to be reinserted into the fiber coiling rack, which is very inconvenient to use. Therefore, a high-stability optical fiber coiling box for mining that can prevent the optical fibers from falling off is needed. Utility Model Content

A receiving tray cover 8 is hinged on the optical fiber receiving tray 2, and a through hole is formed between the lead slot 7 and the receiving tray cover 8;

[0033] The buckle assembly 3 includes a plurality of heat shrink tube buckles 9 arranged in the optical fiber receiving tray 2. An annular accommodation groove is formed between the buckle assembly 3 and the inner peripheral wall of the optical fiber receiving tray 2;

[0034] A plurality of wire clamp assemblies 4 are all disposed in the annular accommodation groove, and the plurality of wire clamp assemblies 4 are located on both sides of the buckle assembly 3 along the Y axis;

[0035] Among them, the wire clamp assembly 4 includes a fixed clamping portion 41, a sliding clamping portion 42 abutted against one side of the fixed clamping portion 41, a fixed block 43 disposed on the side of the sliding clamping portion 42 away from the fixed clamping portion 41, and an elastic member 44 connected between the sliding clamping portion 42 and the fixed block 43. A guiding convex portion 10 is provided at the bottom of the optical fiber receiving tray 2, and a guiding groove 11 adapted to the shape of the guiding convex portion 10 is provided at the bottom of the sliding clamping portion 42. The guiding convex portion 10 is disposed in the guiding groove 11, and a clamping hole 12 is provided between the fixed clamping portion 41 and the sliding clamping portion 42.

[0036] In this technical solution, the housing of the box body 1 is made of a strong and durable metal material. The surface of the box body 1 can be subjected to electrostatic spraying treatment to improve the anti-corrosion property and at the same time improve the aesthetics. The box cover 5 can be hinged to the box body 1 or can be fixed to the top of the box body 1 using fastening screws, and the installation is convenient and reliable.

[0037] A plurality of wiring holes 6 opened on the box body 1 are used to access an optical cable composed of a plurality of optical fibers into the box body 1. Subsequently, the optical cable is passed through the lead slot 7 and then the optical fibers are coiled in the optical fiber receiving tray 2.

[0038] The heat shrink tube buckle 9 is used to fix the heat shrink tube on the optical fiber connector, so that the heat shrink tube is clamped in the card slot of the heat shrink tube buckle 9. The plurality of heat shrink tube buckles 9 of the buckle assembly 3 are arranged, so that the optical fibers are arranged more neatly and the plurality of optical fibers are prevented from being wound around each other.

[0039] After a plurality of optical fibers pass through the lead slot 7, they are then coiled along the annular accommodation groove, and are clamped and fixed by the wire clamp assembly 4 to prevent the optical fibers from coming out. A through hole is formed between the lead slot 7 and the receiving tray cover 8, and the receiving tray cover 8 can limit the optical fibers on the lead slot 7.

[0040] The fixed clamping portion 41 and the peripheral edge of the optical fiber receiving tray 2 can be an integrally formed structure, and the fixed block 43 can be fixed to the bottom of the optical fiber receiving tray 2 using fastening screws.

[0041] The sliding clamping part 42 can slide on the upper surface of the bottom of the optical fiber receiving tray 2. The guiding protrusion 10 is arranged in the guiding groove 11 to guide the sliding clamping part 42, so as to ensure that the sliding clamping part 42 can slide back and forth smoothly. The cross-sections of the guiding protrusion 10 and the guiding groove 11 can be T-shaped, so as to limit the vertical position of the sliding clamping part 42. The elastic member 44 can be an elastic and stretchable structure, such as a spring. Through the elasticity of the elastic member 44, it can be ensured that the sliding clamping part 42 resets itself and clamps a number of optical fibers in the clamping hole 12.

[0042] When using the wire clamp assembly 4 to fix the optical fiber, first move the sliding clamping part 42, the elastic member 44 is compressed, and a clamping opening is formed between the sliding clamping part 42 and the fixed clamping part 41; after a number of optical fibers pass through the clamping opening, release the hand, and the elastic member 44 recovers its deformation, so that the sliding clamping part 42 is reset and contacts the surface of the fixed clamping part 41, thereby limiting the position of a number of optical fibers, preventing the optical fibers from falling out, and improving the stability of the optical fibers installed in the optical fiber receiving tray 2.

[0043] When taking out the optical fiber, first move the sliding clamping part 42 to form a clamping opening between the sliding clamping part 42 and the fixed clamping part 41 to take out some optical fibers, then let go, the elastic member 44 recovers its deformation, and the sliding clamping part 42 is reset and abuts against the surface of the fixed clamping part 41.

[0044] Embodiment 2:

[0045] This embodiment provides a mining optical fiber anti-dropping fiber box, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] In the present technical solution, when using the wire clamp assembly 4 to fix the optical fiber, there is no need to manually move the sliding clamping part 42. Instead, a number of optical fibers are directly pressed downward along the wire entry groove 15. The sliding clamping part 42 slides toward the fixed part under the external force, and the elastic part 44 is compressed. A number of optical fibers can smoothly enter the clamping hole 12. Then the elastic part 44 restores its deformation and the sliding clamping part 42 is reset, thereby preventing the optical fiber from falling out.

[0048] When taking out the optical fiber, first move the sliding clamping part 42 to form a clamping opening between the sliding clamping part 42 and the fixed clamping part 41 to take out some optical fibers, then let go, the elastic member 44 recovers its deformation, and the sliding clamping part 42 is reset and abuts against the surface of the fixed clamping part 41.

Directly lift several optical fibers upward along the wire outlet groove 18, the sliding clamping part 42 slides towards the fixed part under the external force, the elastic part 44 is compressed, and several optical fibers can be smoothly taken out from the clamping hole 12. Subsequently, the elastic part 44 restores its deformation and the sliding clamping part 42 resets.

[0052] Furthermore, anti-slip pads 19 are provided on both the clamping groove 16 and the limiting surface 14.

The surface of the anti-slip pad 19 can also be provided with anti-slip convex lines to improve the friction of the wire clamp assembly 4. After several optical fibers are placed in the clamping hole 12, the anti-slip pad 19 can prevent the optical fibers from moving in the horizontal direction, further improving the stability of the optical fiber installed in the optical fiber storage tray 2.

[0054] Through the setting of the wire outlet groove 18, there is no need to manually move the sliding clamping part 42, the operation is more convenient and efficient, and the work efficiency is further improved.
