[0005] Preferably, a rubber pad is sleeved on the other externally threaded body, and a lower nut threadably connected to the externally threaded body is arranged on the outer side of the rubber pad.

[0006] Preferably, the limiting assembly comprises an externally threaded rod threadably connected to a fixed outer ring, the bottom of the externally threaded rod is fixedly connected to a limiting rod, a positioning body is provided at the bottom of the limiting rod, and the positioning body is inserted into a limiting hole.

[0007] Preferably, a rotating block for easy rotation is fixedly provided at one end of the externally threaded rod, and a conical sealing body is provided inside the externally threaded body which can be continuously compressed and sealed by the downward rotation of the upper nut.

[0008] Preferably, the positioning body is made of soft rubber material, and the number of the limiting holes is an integral multiple of the number of the threaded holes.

[0009] The technical effects and advantages of the utility model are as follows: the outer shell is made of brass material, which is more cold-resistant than ordinary plastic materials. In the process of tightening the upper nut, the inner wall of the center block is made into a conical sealing body, which further locks the cable box to increase the sealing performance. The existing rubber pad is improved into a cold-resistant rubber pad, and the rubber is soft and elastic. Then, the upper nut is continuously rotated to fix it to the final position. Because the occasions where the utility model is used require long-term use, the rotation of the limit assembly is used to insert the fixed outer ring and the inside of the limit hole, so as to limit the relative position between the fixed outer ring and the center block, thereby preventing the upper nut from loosening due to external influences, and thus avoiding leakage in the sealed state.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The utility model provides an export-type protective coil as shown in the figure, comprising a center block 1, wherein external threaded bodies 5 are fixedly arranged on the upper and lower sides of the center block 1, an upper nut 3 is threadedly connected to one of the external threaded bodies 5, a fixed outer ring 4 is processed on the outer edge of the bottom of the upper nut 3, a plurality of threaded holes 8 are processed on the fixed outer ring 4, a plurality of limiting holes 6 are processed on the center block 1, a limiting component 2 is arranged between the limiting holes 6 and the threaded holes 8, the limiting component 2 is threadedly connected to the threaded holes 8 and is inserted into the limiting holes 6, and a positioning body 204 is used to rub and bend into each of the limiting holes 6, so that the staff can see at a glance whether the limiting holes 6 and the threaded holes 8 can be limited and fixed.

[0017] Specifically, a rubber pad 7 is sleeved on the other external threaded body 5 , and a lower nut 9 threadedly connected to the external threaded body 5 is arranged on the outer side of the rubber pad 7 .

[0018] Specifically, the limiting assembly 2 includes an externally threaded rod 202 threadedly connected to the fixed outer ring 4 , a limiting rod 203 is fixedly connected to the bottom of the externally threaded rod 202 , a positioning body 204 is provided at the bottom of the limiting rod 203 , and the positioning body 204 is inserted into the limiting hole 6 .

[0019] Specifically, a rotating block 201 for easy rotation is fixedly provided at one end of the external threaded rod 202, and a conical sealing body 10 is provided inside the external threaded body 5, which can be continuously compressed and sealed by the upper nut 3 rotating downward. When the inner wall of the central block 1 is made into a conical sealing body 10 and the upper nut 3 is tightened, the cable box is further locked to increase the sealing performance.

[0020] Specifically, the positioning body 204 is made of soft rubber material, and the number of the limiting holes 6 is an integral multiple of the number of the threaded holes 8, which limits and fixes the relative position between the outer ring 4 and the center block 1, thereby preventing the upper nut 3 from loosening due to external influences.

[0021] Working principle: When using the utility model, the whole body is made of brass material, which is more cold-resistant than ordinary plastic materials. When the inner wall of the center block 1 is made into a conical sealing body 10 and tightened by the upper nut 3, the cable box is more tightly locked to increase the sealing performance. The existing rubber pad is improved to a cold-resistant rubber pad, and the rubber is soft and elastic. Then, the upper nut 3 is continuously rotated to fix it to the final position. Because the occasions where the utility model is used need long-term use, the rotation of the limit component 2 is used to insert the fixed outer ring 4 and the limit hole 6, so as to limit the relative position between the fixed outer ring 4 and the center block 1, thereby preventing the upper nut 3 from being loosened due to external influences, and also avoiding the leakage of the sealing state;

[0022] Then, the positioning body 204 is made of soft rubber, which can drive the limit assembly 2 to rotate during the rotation of the upper nut 3, so that the positioning body 204 can be rubbed and bent into the limit holes 6 one by one, so that the staff can see at a glance whether the limit hole 6 and the threaded hole 8 can be limited and fixed, and then the limit assembly 2 is rotated to rotate the limit rod 203 part of the limit assembly 2 to the inside of the limit hole 6 for final limiting.

[0023] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
