[0024] The effect achieved by the entire embodiment 1 is that, first, a group of threaded holes 2 4 on the top of the lower box body 1 is aligned with a group of threaded holes 4 9 on the top of the upper box body 8. At this time, a group of screws 2 10 are passed through the threaded holes 2 4 and the threaded holes 4 9 at the same time to connect and fix the upper box body 8 and the lower box body 1. At the same time, a sealing strip 5 is provided between the upper box body 8 and the lower box body 1 to prevent moisture from penetrating into the box, thereby avoiding problems such as performance degradation and short circuit of the optical fiber connector due to contact with moisture, thereby ensuring stable and reliable communication. In addition, the sealing strip 5 can well isolate external dust, keep the box clean, and ensure the high efficiency of optical fiber transmission.

[0025] Example 2, as Figure 1-Figure 4As shown, four positioning cylinders 11 are fixedly installed on the inner surface wall of the upper box body 8, a bracket 12 is provided at the bottom of the inner wall of the lower box body 1, and four connecting plates 13 are fixedly installed on the top of the bracket 12. Rubber strips 14 are provided on the tops of the four connecting plates 13, and threaded holes 5 15 are provided on the tops of the four rubber strips 14. Four connecting plates 2 16 are fixedly installed on the top of the bracket 12, and a group of threaded holes 6 17 are provided on the tops of the four connecting plates 2 16. The inner surfaces of the four threaded holes 5 15 are threadedly connected with screws 3 18, and the outer surfaces of the four screws 3 18 are threadedly connected with the inner surfaces of the four threaded holes 6 17. Four positioning rods 19 are fixedly installed on the top of the bracket 12, and two rubber strips 20 are fixedly installed on the inner surface wall of the lower box body 1.

Two threaded holes 8 22 are provided on the top of the lower box body 1, and screws 4 23 are threadedly connected to the inner surfaces of the two threaded holes 8 22.

[0026] The effect achieved by the entire embodiment 2 is that when the device is in normal use, first, the threaded hole 5 15 is adjusted to align with one of the threaded holes 6 17 on the top of the connecting plate 2 16 according to the thickness of the optical cable. Secondly, by inserting the screw 3 18 into the threaded hole 5 15 and the threaded hole 6 17 at the same time, the rubber strip 14 can be used to fasten the optical cable. Then, one end of the rubber strip 2 20 is inserted into the interior of the lower box body 1. At this time, the threaded hole 7 21 and the threaded hole 8 22 are aligned. The two screws 4 23 are respectively inserted into the threaded hole 7 21 and the threaded hole 8 22, so that the two rubber strips 20 can block and fix the placed optical cable, making the storage of the optical cable more stable. The plasticity and elasticity of the rubber strip 14 and the rubber strip 2 20 enable them to adapt to optical cables of different diameters and types. They can be adjusted and fixed according to the actual situation of the optical cable to ensure that the optical cable is firmly fixed in the junction box.

[0027] Working principle: First, when the device is in normal use, a group of threaded holes 24 is opened on the top of the lower box body 1, and a group of threaded holes 49 is opened on the top of the upper box body 8. The upper box body 8 and the lower box body 1 are connected and fixed by inserting a group of screws 210 into the group of threaded holes 24 and the group of threaded holes 49 at the same time. At the same time, the four positioning cylinders 11 can cooperate with the four positioning rods 19. The positioning rods 19 are inserted into the positioning cylinders 11, which can make the connection between the upper box body 8 and the lower box body 1 faster. A sealing strip 5 is placed between the upper box body 8 and the lower box body 1 to ensure tightness. The setting of the seal 5 can wrap the optical cable joint in a sealed environment to prevent it from being damaged by oxidation and moisture, thereby maintaining the stability and reliability of the optical cable transmission. At the same time, four plugs 7 are set on the top of the lower box body 1. The setting of the plug 7 not only improves the sealing performance of the optical cable joint box, but also enhances its protection effect on the optical fiber and the joint. After the optical fiber enters the box body through the plug 7, four connecting plates 13 are fixedly installed on the top of the bracket 12. The tops of the four connecting plates 13 are all provided with rubber strips 14, and the top of the bracket 12 is fixedly installed with Four connecting plates 2 16, each of the four connecting plates 2 16 has a set of threaded holes 6 17 on its top. At this time, the threaded hole 5 15 is adjusted to align with one of the threaded holes 6 17 according to the thickness of the optical fiber, and then the screw 3 18 is passed through the threaded hole 5 15 and the threaded hole 6 17 at the same time to fix the optical cable. The screw 3 18 is used in conjunction with the rubber strip 14 to fix the optical cable. The tightening force of the screw 3 18 can further strengthen the stability of the optical cable. At the same time, the plasticity and elasticity of the rubber strip 14 enable it to adapt to optical cables of different diameters and types. In the optical cable junction box, the rubber strip A 14 can be adjusted and fixed according to the actual situation of the optical cable to ensure that the optical cable is firmly fixed in the junction box. Secondly, two rubber strips 20 are fixedly installed on the inner wall of the lower box body 1. One end of the two rubber strips 20 is inserted into the interior of the lower box body 1. At the same time, threaded holes 7 21 are provided on the tops of the two rubber strips 20, and two threaded holes 8 22 are provided on the top of the lower box body 1. At this time, two screws 4 23 are respectively inserted into the threaded holes 7 21 and the threaded holes 8 22 to block and fix the optical cable stored in the junction box, so that the storage of the optical cable is more stable.
