DETAILED DESCRIPTION

[0019] The technical solution described in this application is further described below in conjunction with the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figures 1 to 5 As shown, the building cable penetration protection structure includes a base 1, wherein the base 1 forms a penetration hole 16 through a circular bottom plate 14 in the middle, and the inner plate 12 and the outer plate 13 formed by an annular plate body are fixedly connected on both sides of the circular bottom plate 14, and a plurality of partitions 15 are distributed between the inner plate 12 and the outer plate 13, and the partitions 15 are evenly distributed in the circumferential direction of the penetration hole 16 and form chambers for accommodating the rubber block 6 and the adjustment fixing rod 2, respectively, and the partitions 15 are fixedly connected to the inner plate 12, the outer plate 13, and the circular bottom plate 14, respectively. A through hole for the rubber block 6 to extend into the penetration hole 16 is processed at the position of the circular bottom plate 14 corresponding to the bottom of the chamber accommodating the rubber block 6, and the top of the rubber block 6 is located in the chamber and a block limiting hole 11 is processed at the top of the rubber block 6.

[0022] The block limiting hole 11 contains a smooth rod section of the adjusting screw 7, and the adjusting screw 7 slides relative to the block limiting hole 11. The adjusting screw 7 also includes a threaded section, and is threadedly connected to the threaded sleeve 8 through the threaded section to achieve self-screwing in and out.

[0023] The threaded sleeve 8 is located on the limit fixing plate 9, and the limit fixing plate 9 is fixed on the adjacent inner plate 12, outer plate 13 and partition 15. A spring 10 is sleeved on the adjusting screw 7 between the limit fixing plate 9 and the top of the rubber block 6, and the top and bottom ends of the spring 10 are in contact with the corresponding limit fixing plate 9 and the top of the rubber block 6 respectively.

[0024] The adjusting fixing rod 2 is threadedly connected to the rotating block 3 . The rotating block 3 is located inside the chamber and is alternately arranged in sequence in the circumferential direction of the penetration hole 16 relative to the adjusting screw rod 7 .

[0025] The two ends of the rotating block 3 are rotatably connected to the inner plate 12 and the outer plate 13 at corresponding positions through the block rotating shaft 4.

[0026] Example 2

[0027] like Figures 1 to 5 As shown, and see Figure 5 The building cable is provided with a protective structure, and the outer peripheral opening of the chamber accommodating the adjusting screw 7 is blocked by a protective cover 5, and the protective cover 5 is bent downward at the end surface in contact with the partition 15, and the end surface formed after bending is in contact with the partition 15. The inner plate 12 and the outer plate 13 are annular plates, and the rubber block 6 is processed with an arc surface at the end surface in contact with the cable.

[0028] The structure and connection relationship of the remaining parts are the same as those described in Example 1. To avoid making the specification too long, they will not be described here in detail. Those skilled in the art can refer to the technical solution described in Example 1 for understanding.

[0029] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles played by the technical features in the present technical solution, so as to help technicians in this field to fully understand the technical solution and reproduce it.

[0030] In the present application, the inner plate 12, the outer plate 13 and the circular bottom plate 14 constitute the base 1, and the plurality of partitions 15 evenly distributed around the circular bottom plate 14 constitute chambers for accommodating the rubber block 6 and the adjustment fixing rod 2. The adjustment fixing rod 2 and the rubber block 6 are alternately arranged in the circumference of the circular bottom plate 14. In the present application, the adjustment fixing rod 2 can fix the base 1 at the position of the wall installation hole by screwing in and out relative to the base 1. The rubber block 6 can contact the outer surface of the cable by moving relative to the base 1.

[0031] The adjustment of the rubber block 6 relative to the base 1 is achieved through the block limit hole 11 and the adjusting screw 7, and the application of contact surface pressure is assisted by the spring 10. Specifically, the adjusting screw 7 slides relatively in the block limit hole 11, and the bottom end of the block limit hole 11 and the bottom end of the adjusting screw 7 leave a distance for the rubber block 6 to move. The spring 10 can apply a force to the relatively moving rubber block 6 and the adjusting screw 7.

[0032] The adjusting screw 7 is connected to the threaded sleeve 8 by a thread, and the threaded sleeve 8 is fixedly connected to the limit fixing plate 9. The periphery of the limit fixing plate 9 is respectively connected and fixed to the inner plate 12, the outer plate 13 and the partition plate 15 at the corresponding positions. The above structure can realize the relative adjustment of the adjusting screw 7 itself, and then cooperate with the rubber block 6 to realize the displacement adjustment of the rubber block 6, so as to meet the adaptation of the rubber block 6 to cables with different outer diameters.

[0033] In the present application, the adjusting fixing rod 2 is threadedly connected to the rotating block 3, and the two ends of the rotating block 3 are rotatably connected to the inner plate 12 and the outer plate 13 through the block rotating shaft 4. The purpose of the above structure is to adjust the angle of the adjusting fixing rod 2 when connected, meet the installation requirements of the installation position, and improve flexibility.

[0034] In the present application, by providing a protective cover 5, the rubber block 6, the adjusting screw 7 and other structures are protected to improve the stability of the internal structure. In the present application, by not sealing the chamber where the rotating block 3 is provided, the stability of the installation itself can be improved by cooperating with the blocking material after the installation is completed, and the installation material (such as concrete) can enter the chamber where the adjusting fixing rod 2 and the rotating block 3 are installed, thereby increasing the contact area and improving the installation quality.

[0035] In the present application, the cable is inserted through the through hole 16 and contacts the end surface of the rubber block 6 , and the gap between adjacent rubber blocks 6 can be sealed for a second time by sealing glue.

[0036] Finally, although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
