[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3The utility model provides an embodiment: a fusion splicing device for communication cables, including a fusion splicing box 1. The fusion splicing box 1 serves as the main structure of the entire device and provides a stable installation foundation and protection space for other components. The external front end of the fusion splicing box 1 is fixedly connected to a controller 2. The controller 2 is the control core of the entire fusion splicing device. It is equipped with high-precision electronic components and an intelligent control system, which can accurately adjust various parameters in the fusion splicing process, such as temperature, time, etc. The operator can conveniently set and adjust the fusion splicing parameters through the operation interface on the controller 2 to meet the fusion splicing requirements of different types of communication cables. The external top of the fusion splicing box 1 is fixedly connected to a fusion interface 3. The fusion interface 3 is a key part specially designed for realizing the fusion of communication cables. Limiting grooves 4 are provided on the left and right sides of the top of the fusion splicing box 1. The function of the limiting grooves 4 is to provide guidance and positioning for the snap-fit ​​block 23 on the sealing cover 13 to ensure that the sealing cover 13 can be accurately closed on the fusion splicing box 1. The machining precision of the limiting groove 4 is very high, and its inner wall is smooth and flat, which can reduce the friction of the locking block 23 during the sliding process, making the opening and closing of the sealing cover 13 smoother. The left and right sides of the outside of the welding box 1 are rotatably connected to the rotating rod 5. The rotating rod 5 is an important component for realizing the locking and unlocking of the sealing cover 13. The front end of the outside of the rotating rod 5 is fixedly connected to the protrusion 6. The protrusion 6 is fixed on the rotating rod 5 and moves with the rotation of the rotating rod 5. The shape and size of the protrusion 6 match the oblique groove of the inclined block 10. When the protrusion 6 rotates, it will slide in the oblique groove, thereby pushing the inclined block 10 to move. The outside of the protrusion 6 is fixedly connected to the inside of the welding box 1. This fixed connection method ensures that the position of the protrusion 6 in the welding box 1 is stable and will not loosen or shift. At the same time, the welding box 1 provides support and protection for the protrusion 6, so that it can play a stabilizing role in the locking and unlocking process of the sealing cover 13;

[0032] The outside of the rotating rod 5 is rotatably connected to the bearing column 7, and the inside of the bearing column 7 is rotatably connected to the transmission rod 8. The outside of the transmission rod 8 is rotatably connected to the inside of the welding box 1, and the transmission rod 8 is rotatably connected to the inside of the welding box 1. The outside of the transmission rod 8 is fixedly connected to a spring 9, which plays a buffering and resetting role in the locking and unlocking process of the sealing cover 13. The left end of the spring 9 is fixedly connected to the inside of the bearing column 7, and the right end of the spring 9 is fixedly connected to the outer rear end of the inclined block 10. The outer rear end of the transmission rod 8 is fixedly connected to the inclined block 10. The outside of the protrusion 6 is rotatably connected to the oblique groove of the inclined block 10, and the outside of the inclined block 10 is rotatably connected to the inside of the bearing column 7;

[0033] The external rear end of the welding box 1 is fixedly connected with a connecting component for closing, and the connecting component includes a connecting block 11, the external part of the connecting block 11 is fixedly connected to the external rear end of the welding box 1, and the internal rotation of the connecting block 11 is connected to the rotating block 12, and the external part of the closing component is fixedly connected with a sealing cover 13. The main function of the sealing cover 13 is to provide sealing protection for the welding box 1 during the welding process to prevent impurities such as dust and moisture from entering the welding box 1 and affecting the welding quality. The external front end of the sealing cover 13 is fixedly connected with a handle 14, and the internal bottom end of the sealing cover 13 is fixedly connected with a sealing ring 15. The front side of the external bottom end of the sealing cover 13 is fixedly connected with two snap blocks 23, and the external parts of the two snap blocks 23 are slidably connected to the internal parts of the two limit grooves 4, and the internal parts of the snap blocks 23 are snapped with the external parts of the transmission rod 8.

[0034] Reference Figure 1 、 Figure 2 、 Figure 4 , the left and right sides of the outer top of the welding box 1 are fixedly connected with the wire-paying block 16. The function of the wire-paying block 16 is to fix and support the communication cable so that it maintains a stable position during the welding process. The internal thread of the wire-paying block 16 is connected with a screw 17. The screw 17 is the key component for adjusting the position of the clamping plate 18. By rotating the screw 17, the distance between the clamping plate 18 and the clamping plate 22 can be changed to adapt to communication cables of different diameters;

[0035] The outer rear end of the screw 17 is fixedly connected to a clamping plate 18, and the left and right sides of the interior of the wire-paying block 16 are slidably connected to sliding rods 19. The sliding rods 19 serve to guide and support the clamping plate 18. The outer parts of the two sliding rods 19 are fixedly connected to the outer rear end of the clamping plate 18, and the outer parts of the sliding rods 19 on both sides are fixedly connected to springs 20. The outer rear end of the sliding rod 19 is fixedly connected to a limiting block 21. The function of the limiting block 21 is to prevent the sliding rod 19 from escaping from the wire-paying block 16. The interior of the wire-paying block 16 is fixedly connected to a clamping plate 22. The outer part of the clamping plate 18 is in contact with the outer part of the clamping plate 22. When the screw 17 is rotated to adjust the position of the clamping plate 18, the clamping plate 18 will gradually approach or move away from the clamping plate 22, thereby achieving clamping of cables of different diameters.

[0036] Working principle: First, by rotating the screw 17, the screw 17 drives the clamping plate 18 to move. During this process, the sliding rod 19 connected to the clamping plate 18 slides in the pay-off block 16, and the spring 20 is compressed or stretched, and then drives the clamping plate 18 to cooperate with the clamping plate 2 22 fixed in the pay-off block 16 to tightly fix the cable.

[0037] When the sealing cover 13 needs to be closed, the handle 14 at the front end of the sealing cover 13 is held and the sealing cover 13 is rotated downward, and the sealing cover 13 drives the locking block 23 to move downward. When the locking block 23 contacts the welding box 1, the locking block 23 will be inserted into the limit groove 4, and then the rotating rods 5 on both sides of the welding box 1 are rotated, which will then drive the protrusions 6 to rotate and contact the inclined grooves of the inclined block 10. When the inclined block 10 rotates, it will drive the transmission rod 8 to rotate and slide forward, and then the transmission rod 8 is inserted into the locking block 23 inside the limiting groove 4 for insertion and limitation. When the sealing cover 13 is completely closed on the welding box 1, the sealing ring 15 at the bottom end of the sealing cover 13 is in close contact with the welding box 1 to achieve sealing, providing a relatively closed environment for cable welding, preventing dust and other impurities from entering, and ensuring the welding quality.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
