[0022] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0023] Embodiment:

[0024] like Figure 1-4 As shown, the utility model provides an external distribution box, characterized in that: it includes a distribution box body 1 and a distribution box hanging ear 2 arranged at the end of the distribution box body 1, a horizontal hanging rod 3 is arranged between the distribution box hanging ears 2, and two groups of movable active connecting members 4 are arranged in the horizontal hanging rod 3. The movable connecting member 4 includes a movable plate 41 attached to the surface of the horizontal hanging rod 3, a fixing bolt 42 that fixes the movable plate 41 to the surface of the horizontal hanging rod 3, a fastening bolt 43 that adjusts the distance between the two groups of movable plates 41, and a fixing strap 5 is connected between the two groups of fixing bolts 42;

[0025] The fixing strap 5 is wrapped around the external rod, and the distance between the two sets of movable plates 41 is adjusted by tightening the bolts 43. The movable plates 41 tighten the fixing strap 5 during the opposite movement, and the fixing strap 5 is wrapped around the surface of the column, so that the fixing strap 5 is stabilized on the surface of the column. The fixed fixing strap 5 provides a setting point for the horizontal hanging rod 3, and the horizontal hanging rod 3 provides a setting point for the setting of the distribution box hanging ear 2.

[0026] A transverse groove for connecting the distribution box hanging ear 2 and the movable connecting piece 4 is opened in the middle of the transverse hanging rod 3. The transverse groove provides a non-fixed connection point for the distribution box hanging ear 2 and the movable connecting piece 4. The transverse hanging rod 3 provides sufficient space and points for the setting of the distribution box hanging ear 2, thereby improving the setting flexibility.

[0027] The movable plate 41 is designed in an "L" shape, and the transverse part of the movable plate 41 is provided with a slot with the same specifications as the transverse slot in the transverse hanging rod 3. The fixing bolt 42 passes through the slot in the movable plate 41 and the transverse slot in the transverse hanging rod 3. The movable plate 41 moves on the transverse hanging rod 3 through the fixing bolt 42 to adjust the distance between the two groups of movable plates 41, so that the movable plate 41 can pull the fixing strap 5 to tighten the fixing strap 5, and the tightened fixing strap 5 can be fixed on the surface of the column. The middle part of the fixing bolt 42 is designed in a rectangular shape. The middle rectangular part of the fixing bolt 42 is consistent with the specifications of the slot in the movable plate 41 and the transverse slot in the transverse hanging rod 3. After the fixing bolt 42 penetrates into the movable plate 41 and the transverse hanging rod 3, the rotation of the movable plate 41 relative to the transverse hanging rod 3 can be limited, so that the movable plate 41 can maintain the connection stability.

[0028] The total length of the fastening bolt 43 is longer than the diameter of the circle formed by the fixing strap 5, and the length of the thread on the surface of the fastening bolt 43 is longer than the radius of the circle formed by the fixing strap 5. After the fixing strap 5 is sleeved onto the outside of the column, the fastening bolt 43 provides sufficient travel for the movable plate 41 to tighten the fixing strap 5, so that the fixing strap 5 can be better fixed on the outer surface of columns of different specifications.

[0029] The movable connecting member 4 also includes a fastening spring 44, which is sleeved on the outside of the fastening bolt 43 and respectively contacts the two groups of movable plates 41. Under the elastic force of the fastening spring 44, when the fastening bolt 43 pushes the movable plate 41, the movable plate 41 will simultaneously compress the fastening spring 44, so that the fastening spring 44 contracts and accumulates force. After accumulating force, the fastening spring 44 will push the movable plate 41 in the reverse direction, so that the fastening bolt 43 always remains in a tight state to ensure the stability of the connection.

[0030] The fixed strap 5 and the movable plate 41 are movably connected. The movable connection method can keep the connection between the fixed strap 5 and the movable plate 41 movable, so as to better adapt to connection angles of different specifications. The inner wall surface of the fixed strap 5 is ground. The ground surface of the inner wall of the fixed strap 5 can enable the fixed strap 5 to obtain greater contact friction when tightened and close to the outer surface of the column, thereby improving the fixing stability.

[0031] The inner wall surface of the fixing strap 5 is also provided with several groups of auxiliary fixing parts 51 of the strap, and the auxiliary fixing parts 51 of the strap are evenly spaced on the inner wall of the fixing strap 5. When the fixing strap 5 is put on the surface of the column and tightened, the auxiliary fixing parts 51 of the strap can contact the column before the fixing strap 5, so that the fixing strap 5 can fill the gap between the fixing strap 5 and the column during the tightening process, avoid incomplete contact between the fixing strap 5 and the column, and increase the stability when contacting with the column.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
