[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figures 1-4This utility model provides a fiber optic cable distribution frame for mining communications, including a protective cover 1. A screw 2 is threadedly connected inside the protective cover 1. A turbine 21 is fixedly connected to one end of the screw 2. A nut 22 is threadedly connected to the surface of the screw 2. An upper inclined block 23 is fixedly connected to the side wall of the nut 22. A connecting slider 24 is fixedly connected to the side wall of the upper inclined block 23. A vertical sliding groove 27 is formed on the inner wall of the protective cover 1. A sliding rod 28 is slidably connected inside the vertical sliding groove 27. A lower inclined block 29 is fixedly connected to one end of the sliding rod 28. An inclined sliding groove 4 is formed on the surface of the lower inclined block 29. An arc-shaped block is fixedly connected to the bottom of the lower inclined block 29. By setting up a linkage structure between the screw 2 and the turbine 21, precise clamping control of the optical fiber cable is achieved. The tightness of the optical fiber cable's fixation directly affects the signal transmission stability. If it is too loose, it is easy to cause poor contact due to vibration; if it is too tight, it may damage the cable. The screw 2 is threadedly connected to the protective cover 1. When the turbine 21 rotates, it can drive the screw 2 to rotate synchronously. The rotational motion of the turbine 21 is converted into the linear motion of the nut 22 by utilizing the thread transmission characteristics. With the inclined surface contact between the upper inclined block 23 and the lower inclined block 29, the arc-shaped block at the bottom of the lower inclined block 29 can smoothly adjust the clamping force. By setting the sliding cooperation between the connecting slider 24 and the inclined groove 4, the clamping is improved. The mechanism's operational stability and durability are ensured by connecting slider 24, which is fixed to the side wall of upper inclined block 23 and forms an embedded sliding connection with the inclined groove 4 on the surface of lower inclined block 29. This structure not only guides the horizontal movement of upper inclined block 23 into the vertical movement of lower inclined block 29, but also reduces jamming caused by dust intrusion through the precise cooperation between the groove and slider. By setting the guide structure of vertical groove 27 and sliding rod 28, the precise orientation of the clamping action is ensured. Fiber optic cable distribution frame needs to fix multiple cables in an orderly manner. If the clamping components are misaligned, the cables may be squeezed together or fall off. Vertical groove 27 is opened on the inner wall of protective cover 1, and sliding rod 28... One end is fixed to the downward inclined block 29, and the other end is embedded in the vertical sliding groove 27 to form a sliding constraint, which strictly restricts the downward inclined block 29 to move only in the vertical direction, and avoids horizontal displacement or rotation during clamping. By setting the arc-shaped block at the bottom of the downward inclined block 29, flexible protection and adaptability fixing of the optical fiber cable are achieved. The optical fiber cables used in mining communication have various specifications and different diameters. Traditional rigid clamps are prone to fixing failure or cable damage due to size mismatch. The arc-shaped block adopts an arc-shaped contact surface design, which naturally fits the outer circle contour of the cable, which can increase the contact area to disperse the clamping force and avoid sheath damage caused by excessive local pressure.

[0019] In the above scheme, the protective cover 1 has round holes 11 on both sides and mounting slots 5 on both sides. By setting the round holes 11, the fiber optic cable can be oriented and the path can be standardized. The round holes 11 are set on both sides of the protective cover 1, providing a clear passage for the cable. The cable corresponds to the round holes 11, realizing the directional guidance of the cable. By setting the mounting slots 5, a stable installation space is provided for the auxiliary protective components. Example

[0020] Please see Figures 1-3 This utility model provides a technical solution: Specifically, a spring 3 is fixedly connected inside the protective cover 1, a connecting plate 31 is fixedly connected to the top of the spring 3, and an arc-shaped cable laying plate 32 is fixedly connected to the top of the connecting plate 31. By setting the combination structure of the spring 3 and the arc-shaped cable laying plate 32, flexible support and dynamic buffering of the optical fiber cable are achieved. The spring 3 is fixed inside the protective cover 1, and its top is connected to the arc-shaped cable laying plate 32 through the connecting plate 31. When external vibration is transmitted to the protective cover 1, the spring 3 can absorb the impact energy through its own elastic deformation, and convert the violent vibration into a slow elastic expansion and contraction motion. The curved contact between the arc-shaped cable laying plate 32 and the cable surface can disperse the support force. Combined with the buffering effect of the spring 3, it can avoid local stress concentration caused by rigid collision of the cable, effectively reducing faults such as sheath cracking and fiber core breakage. By setting the elastic adjustment characteristics of the spring 3, adaptive support for cables of different diameters can be achieved.

[0021] Furthermore, the inclined slide 4 is slidably connected to the connecting slider 24. By setting the sliding connection between the inclined slide 4 and the connecting slider 24, the transmission direction of the clamping mechanism is precisely constrained. In the clamping action of the mine communication distribution frame, the upper inclined block 23 moves horizontally with the nut 22. The power needs to be stably converted into the vertical clamping force of the lower inclined block 29. If the transmission direction is deviated, it will cause the arc block to deviate in the clamping position, or even damage the cable. The inclined slide 4 is processed according to the preset inclination angle. When the connecting slider 24 is embedded in the groove and slides, the groove wall forms a rigid guide, which strictly restricts the slider to move only along the slide trajectory, thereby forcing the horizontal displacement of the upper inclined block 23 to be converted into the vertical displacement of the lower inclined block 29 in a fixed proportion. Example

[0022] Please see Figure 4 This utility model provides a technical solution: Specifically, an inner airbag 51 is provided inside the mounting groove 5, and an elastic compression block 52 is provided at the bottom of the inner airbag 51. By setting the inner airbag 51 and the elastic compression block 52 inside the mounting groove 5, adaptive sealing protection is achieved at the point where the optical fiber cable passes through. When the cable passes through the round hole 11, the elastic compression block 52 is limited by the side wall of the mounting groove 5 and naturally squeezes the inner airbag 51 inward, so that it fits tightly along the outer circumference of the cable and fills all the gaps between the round hole 11 and the cable. By setting the combined structure of the inner airbag 51 and the elastic compression block 52, flexible buffer protection for the optical fiber cable is achieved.

[0023] It should be noted that the protective cover 1 and the connecting plate 31 are elastically connected by spring 3. By setting the elastic connection between the protective cover 1 and the connecting plate 31 by spring 3, dynamic pressure balance protection of the optical fiber cable is achieved. By setting the elastic connection between the protective cover 1 and the connecting plate 31 by spring 3, the anti-interference ability of the patch panel against severe vibration in the mine is improved.

[0024] Working principle: A separate motor drives the turbine 21 to rotate the screw 2. The screw drive causes the nut 22 to move the upper inclined block 23 horizontally. The connecting slider 24 of the upper inclined block 23 slides along the inclined groove 4 of the lower inclined block 29, converting the horizontal motion into the vertical motion of the lower inclined block 29. With the guidance and constraint of the vertical groove 27 and the sliding rod 28, the arc-shaped block at the bottom of the lower inclined block 29 is ensured to accurately press the cable. The round holes 11 on both sides of the protective cover 1 guide the cable to pass through in the correct direction. The inner air bladder 51 in the placement groove 5 is pressed tightly against the cable under the action of the elastic compression block 52, achieving a seal at the insertion point. The arc-shaped cable release plate 32 connected to the bottom spring 3 forms a flexible support. It cooperates with the upper arc-shaped block and balances the clamping force through the elastic buffer of the spring 3. It can adapt to cables of different diameters and absorb vibration. The overall structure achieves stable fixation and safe protection of optical fiber cables in the mining environment through the synergy of mechanical transmission, elastic buffer and sealing protection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
