[0022] 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.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A replaceable fiber optic communication link device for oil wells includes a main body 1, a bottom shell 2 fixedly connected to the top of the main body 1, an upper shell 3 fixedly connected to the top of the bottom shell 2, a first sleeve 7 and a second sleeve 10 fixedly connected to both sides of the longitudinal end of the bottom shell 2, and a first frame 8 and a second frame 11 fixedly connected to both sides of the longitudinal end of the upper shell 3. Fixing components for fixing cables are provided on the outer sides of the first frame 8 and the second frame 11.

[0025] The cable is passed through the first sleeve 7 and the second sleeve 10. After connecting the cable connector to the main body 1, the bottom shell 2 and the upper shell 3 are combined and fixed together, and then the whole assembly is fixed to the top of the main body 1. At this time, the first sleeve 7 and the first frame 8 form a normally closed opening, and the second sleeve 10 and the second frame 11 form an inlet. Multiple sets of cables are placed in multiple sets of receiving cavities 12. First, the limiting rod 9 of the normally closed opening is locked so that the subsequent pushing and pulling of the cable will not affect the stability of the connection between the cable and the main body 1. Then, the cable is pushed into the receiving cavity 12 until the external cable reaches the appropriate length. Then, the limiting rod 9 of the inlet is locked. This achieves stable cable storage while ensuring the stability of the connection between the cable and the main body 1, thereby improving the stability of the replaceable fiber optic communication link equipment used in oil wells.

[0026] Specifically, such as Figure 2 and Figure 4As shown, a mounting bracket 4 is fixedly connected to the outer wall of the bottom shell 2. The mounting bracket 4 is fixedly connected to the outer wall of the main body 1 via a locking rod 5. A plug bracket 6 is fixedly connected to the outer wall of the upper shell 3. The plug bracket 6 is inserted into the mounting bracket 4. The locking rod 5 passes through the plug bracket 6 and the mounting bracket 4, allowing the upper shell 3 to overlap the top of the bottom shell 2. The plug bracket 6 is inserted into the mounting bracket 4. After the locking rod 5 passes through the mounting bracket 4 and the plug bracket 6, it is screwed onto the outer wall of the main body 1. This achieves the merging of the bottom shell 2 and the upper shell 3, while also fixing the bottom shell 2 to the main body 1. This ensures convenient connection of cables to the bottom shell 2 and the upper shell 3, as well as convenient assembly and disassembly of the bottom shell 2 and the upper shell 3.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, the bottom shell 2 and the upper shell 3 form multiple sets of receiving cavities 12 to prevent the cables from getting tangled together. The fixing component includes two sets of limiting rods 9, and the two sets of limiting rods 9 are respectively screwed to the inner surface of the first frame 8 and the second frame 11. Rotating the limiting rods 9 so that their open ends abut against the outer surface of the cable can achieve cable positioning. The bottom of the main body 1 is fixedly connected to the legs, and the multiple sets of legs are distributed in a rectangular shape to ensure the stability of the position of the main body 1.

[0028] Working principle: The cable is passed through the first sleeve 7 and the second sleeve 10. After connecting the cable connector to the main body 1, the bottom shell 2 and the upper shell 3 are joined and fixed together, and then the whole assembly is fixed to the top of the main body 1. At this time, the first sleeve 7 and the first frame 8 form a normally closed opening, and the second sleeve 10 and the second frame 11 form an inlet. Multiple sets of cables are placed in the corresponding receiving cavities 12. First, the limiting rod 9 of the normally closed opening is locked so that the subsequent pushing and pulling of the cable does not affect the stability of the connection between the cable and the main body 1. Then, the cable is pushed into the receiving cavity 12 until the external cable reaches the appropriate length. Then, the limiting rod 9 of the inlet is locked. The rod 9 is locked to ensure stable cable storage and connection between the cable and the main body 1, thereby improving the stability of the replaceable fiber optic communication link equipment used in oil wells. The upper shell 3 is attached to the top of the lower shell 2, and the insert 6 is inserted into the mounting bracket 4. After the locking rod 5 passes through the mounting bracket 4 and the insert 6, it is screwed onto the outer wall of the main body 1. This allows the lower shell 2 and the upper shell 3 to be merged and fixed to the main body 1. This ensures convenient connection between the cable and the lower shell 2 and the upper shell 3, as well as convenient disassembly and assembly of the lower shell 2 and the upper shell 3.

[0029] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
