[0002] With the continuous development of society, the power supply system of building projects has received increasing attention while ensuring people's normal power consumption needs. In order to ensure the safe and reliable operation of the power supply system, a series of specification requirements need to be complied with in building projects. According to the power consumption needs and power supply conditions of the building, a suitable power supply needs to be selected for power supply. At the same time, the power supply needs to be reasonably arranged in the building so that the transmission lines of the power supply system are short, the line loss is small, and it is convenient for the operation and maintenance and repair work of power supply equipment. When there are line requirements for temporary or short-term use involving light strip decoration needs or other external connections in public buildings, most of these lines are exposed at the edges of the road surface, ground or building exterior wall, and are spaced and positioned through fixed wire clips. The rolling of external vehicles or the erosion of the external environment are likely to affect and wear the position of the fixed lines, resulting in potential safety hazards during use. The fixed positions are also prone to loosening. Due to the inconsistent shapes of the fixed positions, the lines are prone to crosstalk and deviate from the original positions to form outward warping and bending. At present, there is a lack of unified, standardized and safe treatment means that can be carried out according to different fixing conditions and fixing requirements. Summary of the Invention

Among them, in combination with Figure 1 and Figure 8 As shown, when the main cover shell 1 includes three support cover shells 4, the three support cover shells 4 include a long support cover shell and two short support cover shells. The long support cover shell is arranged between the two short support cover shells to form a multi-position support effect of long-distance support in the middle and short-distance support at both ends, which is beneficial to the stability of the entire main cover shell 1. When the main cover shell 1 includes a plurality of support cover shells 4, the plurality of support cover shells 4 include a plurality of long support cover shells and two short support cover shells. The plurality of long support cover shells are sequentially connected and coaxially arranged to form a main shell structure, and the two short support cover shells are respectively arranged at both ends of the main shell structure to form a multi-position support effect of long-distance support in the middle and short-distance support at both ends. According to the length of different external wiring 18, the corresponding number of long support cover shells is selected.

One side of each connecting strip 5 is connected to an adjacent supporting cover shell 4 by bonding or other fixing methods, and the other side of each connecting strip 5 is connected to another adjacent supporting cover shell 4 by bonding or other fixing methods. The setting of the connecting strip 5 can realize a large amplitude swinging movement during the flexible connection process, thereby adjusting the relative positions of multiple supporting cover shells 4, so that the multiple supporting cover shells 4 can be adapted to be tightly attached to the shoulders of the surrounding buildings where they are placed, the edges of the facades, corners or other different installation positions, and adapt to different edge positions. While achieving stable attachment, it can also play a protective role for the external wiring 18.

A first set of notch (15) matching its corresponding fixing shaft body (11) is machined on the inner wall of one end of each U-shaped insert (3), and a second set of notch (16) matching its corresponding fixing shaft body (11) is machined on the other end of each U-shaped insert (3).

5. A self-swinging regular-shaped pipe for building external wiring according to claim 1, characterized in that: Each support cover shell (4) is an inverted U-shaped shell. Third protrusions (12) and fourth protrusions (13) are respectively arranged on the inner walls of both sides of each support cover shell (4). A second insertion gap (14) is formed between the third protrusion (12) and the fourth protrusion (13). The longitudinal cross-sectional shape of the plug board (2) is T-shaped, and the plug board (2) is inserted and connected with the second insertion gap (14).

6. The wiring self-swinging regular-shaped pipe for external connection of a building according to claim 1, wherein: The thickness of the connecting bar (5) is less than the thickness of the main cover shell (1).

7. A splicing conduit for external connection of a building, which is composed of a self - swinging regular - shaped conduit for wiring for external connection of a building as described in claims 1, 2, 3, 4, 5 or 6, characterized in that: It includes a plurality of wiring self-swinging regular-shaped tubes (17), and the plurality of wiring self-swinging regular-shaped tubes (17) are detachably connected in sequence to form a total wire passing tube; One end of one of the plurality of wire self-swing regulating tubes (17) is detachably connected to an adjacent wire self-swing regulating tube (17), and the other end of one of the wire self-swing regulating tubes (17) is detachably connected to another adjacent wire self-swing regulating tube (17). Each wire self-swing regulating tube (17) includes a main cover shell (1), an insertion plate (2) and a plurality of U-shaped inserts (3). The main cover shell (1) includes at least three support cover shells (4) and at least two connecting strips (5). At least three support cover shells (4) and at least two connecting strips (5) are alternately connected to form a structure. There is a connecting strip (5) between every two support cover shells (4). A wiring cavity (10) is formed inside at least three support cover shells (4) and at least two connecting strips (5). The insertion plate (2) is detachably connected to the bottom of the wiring cavity (10). One side of each connecting strip (5) is connected to an adjacent support cover shell (4), and the other side of each connecting strip (5) is connected to another adjacent support cover shell (4). An outer placement groove (6) is formed between the outer wall of each connecting strip (5) and the ends of two adjacent support cover shells (4). A U-shaped insert (3) is detachably connected to each outer placement groove (6). When the U-shaped insert (3) is detached from its corresponding outer placement groove (6), the main cover shell (1) is in a self-bending state; when the U-shaped insert (3) is arranged in its corresponding outer placement groove (6), the main cover shell (1) is in a straight fixed state.
