[0046] In the present invention, a first plug block 32 and a first snap-on structure 33 are extended from the first end of the connector 3 toward the splicing end of the first splicing box 1 or the second splicing box 2, and a first plug piece 322 is extended outward from both ends of the first plug block 32 of the connector 3 on one side of the splicing end facing away from the first splicing box 1 or the second splicing box 2, so as to facilitate installation and disassembly by the staff, and also prevent the rotating splicing box or other splicing accessories from falling off, and the size of the first plug piece 322 is set according to the width and height of the splicing piece 4 to be spliced, so as to ensure the beauty and neatness of the spliced ​​splicing piece 4.

[0047] A first slot 13 matching the first plug block 32 and a second snap-on structure 14 matching the first snap-on structure 33 are provided at the splicing ends of the first splicing box 1 and the second splicing box 2; the first end of the connector 3 is plugged and installed in the first slot 13 of the first splicing box 1 or the second splicing box 2 through the first plug block 32 and is snap-fastened with the second snap-on structure 14 through the first snap-on structure 33; the first end of the third conductor 31 of the connector 3 extends out of the first end of the connector 3 and contacts with the second end of the first conductor 11 in the first splicing box 1, or contacts with the second end of the second conductor 21 in the second splicing box 2.

[0048] Among them, the first snap-on structure 33 includes a first snap hook 331 and a first snap groove 332; the second snap-on structure 14 includes a second snap hook 141 arranged at the upper end of the splicing end of the first splicing box 1 or the second splicing box 2 and a third snap hook 142 arranged at the lower end of the splicing end of the first splicing box 1 or the second splicing box 2, the second snap hook 141 and the first snap hook 331 cooperate with each other, and the first snap groove 332 and the third snap hook 142 cooperate with each other; the third snap hook 142 is a spring-loaded structure, and a groove 143 that allows the third snap hook 142 to move is provided at the lower end of the splicing end of the first splicing box 1 and the second splicing box 2 opposite to the third snap hook 142.

[0049] In this embodiment, the first slot 13 is located in the middle position of the splicing end of the first splicing box 1 or the second splicing box 2, the second snap-fit ​​structure 14 is located on the inner wall of the first slot 13, and two third slots 131 are provided in the first slot 13; the first snap-fit ​​structure 33 is located on the first plug-in block 32, and plug-in strips 321 matching the third slots 131 are extended toward the first slot 13 from both side ends of the first plug-in block 32 opposite to the splicing end of the first splicing box 1 or the second splicing box 2.

[0050] The two third slots 131 are respectively located on the two side walls of the first slot 13 or at the two ends of the inner wall of the first slot 13; the two third slots 131 have the same or different structures. When the third slots 131 have the same structure, the connector 3 can be arbitrarily installed at the splicing end of the first splicing box 1 or the second splicing box 2. At this time, the first conductor 11 in the first splicing box 1 or the second conductor 21 in the second splicing box 2 will be in contact and conduction with the third conductor 31 of the connector 3 that is different from the first splicing box 1. In this case, splicing without distinguishing polarity is achieved; when the third slots 131 have different structures, the connector 3 can only be installed at the splicing end of the first splicing box 1 or the second splicing box 2 corresponding to the position of the third conductor 31. At this time, the first conductor 11 in the first splicing box 1 or the second conductor 21 in the second splicing box 2 will be in contact and conduction with the third conductor 31 of the connector 3 that is the same as the first splicing box 1, so as to achieve splicing with distinguishing polarity.

[0051] Preferably, the lower surface of the first hook 331 is a slope, the upper surface of the second hook 141 is a matching slope, and the upper surface of the third hook 142 is a slope, and the first buckle groove 332 matches it. During installation, the first plug block 32 is inserted into the first slot 13. At this time, the two insertion strips 321 are inserted downward along the third slot 131. During the insertion process, the third hook 142 pops into the groove 114. When the lower surface of the first hook 331 and the upper surface of the second hook 141 collide, and the third hook 142 is reset and buckled into the first buckle groove 332, it means that the first plug block 32 is inserted into place and the splicing of the splicing piece 4 is completed. When disassembling, pinch the third hook 142 to take out the splicing.

[0052] In the present invention, the first splicing box 1 and / or the second splicing box 2 includes a plurality of splicing ends arranged outside the rotating part; the plurality of splicing ends of the first splicing box 1 and the second splicing box 2 are evenly distributed along the rotating part to realize the splicing of a plurality of splicing pieces 4.

[0054] In this embodiment, the splicing piece 4 includes a guide rail. When the first splicing box 1 and the second splicing box 2 both include a splicing end arranged outside the rotating portion, the end-to-end splicing between two adjacent guide rails is achieved. The splicing method is as follows: Figure 6-7 As shown: the adjacent guide rails are spliced ​​by inserting a connecting head 3 therein and plugging it into the splicing end of the first splicing box 1 or the second splicing box 2 of the rotating splicing box. At this time, the fourth conductor 34 located at the second end of the connecting head 3 extends out of the two side surfaces of the connecting head 3 to contact and conduct with the guide rails.

[0055] When the first splicing box 1 and / or the second splicing box 2 includes two splicing ends arranged outside the rotating part, splicing of opposite ends of three or four guide rails is achieved, and the splicing angle between two adjacent guide rails is adjusted by the rotating part to achieve splicing at any angle.

[0056] Example 2

[0057] The difference between this embodiment and the first embodiment is that the first slot 13 is arranged at a different position.

[0058] In this embodiment, if Figure 8-9 As shown: the first slots 13 are located at both ends of the splicing end of the first splicing box 1 or the second splicing box 2, the first plug-in blocks 32 extend along both sides of the first end of the connector 3 toward the splicing end of the first splicing box 1 or the second splicing box 2, and the first buckle structure 33 is located between the two first plug-in blocks 32; the two first slots 13 located on both sides of the splicing end of the first splicing box 1 or the second splicing box 2 have the same or different structures. When the structures of the first slots 13 are the same, the connector 3 can be arbitrarily installed at the splicing end of the first splicing box 1 or the second splicing box 2. At this time, the first conductor 11 in the first splicing box 1 or the second conductor 21 in the second splicing box 2 will be in contact and conductive with the third conductor 31 of the connector 3 that is different from its polarity. In this case, splicing without distinguishing polarity is achieved; when the structures of the first slots 13 are different, the connector 3 can only be installed at the splicing end of the first splicing box 1 or the second splicing box 2 corresponding to the position of its third conductor 31. At this time, the first conductor 11 in the first splicing box 1 or the second conductor 21 in the second splicing box 2 will be in contact and conductive with the third conductor 31 of the connector 3 that is the same as its polarity, achieving splicing with distinguishing polarity.

[0059] When this embodiment is applied to the guide rail splicing of the embodiment 1, the first inserting pieces 322 do not need to be provided at both ends of the first inserting block 32 of the joint head 3 facing away from the splicing end of the first splicing box 1 or the second splicing box 2 .

The opposite ends of the first blade 511 and the second blade 512 extend in the direction of the rotating part of the first splicing box 1 or the second splicing box 2 installed thereon to match the arc structure. The first blade 511 and the second blade 512 are telescoped along the rotating part of the first splicing box 1 and the second splicing box 2 during the rotation of the first splicing box 1 and the second splicing box 2, so as to be folded or unfolded.

[0067] The second rotating blade structure 52 includes a foldable hinge structure, and both ends of the second rotating blade structure 52 are respectively installed in the second buckle groove 15 of the first splicing box 1 and the third buckle groove 25 of the second splicing box 2 located on the same side of the first splicing box 1 and the second splicing box 2 through the second mounting buckle 521. The second rotating blade structure 52 is folded or unfolded along the side walls of the first splicing box 1 and the second splicing box 2 during the rotation of the first splicing box 1 and the second splicing box 2.

[0068] The installation positions of the first rotating blade structure 51 and the second rotating blade structure 52 are set according to the rotation angles of the first splicing box 1 and the second splicing box 2. Preferably, the first rotating blade structure 51 is installed on the outside of the first splicing box 1 and the second splicing box 2, and the second rotating blade structure 52 is installed on the inside of the first splicing box 1 and the second splicing box 2.

[0069] In this embodiment, when the splicing ends of the first splicing box 1 and the second splicing box 2 of the rotating splicing box and the connecting head 3 are spliced ​​using the plug-in structure of embodiment 1, the structure of the connecting head 3 is as follows: Fig.12 As shown: second inserts 323 extend from both ends of the first insert block 32 of the connector 3 facing away from the first splicing box 1 or the second splicing box 2 toward the splicing piece 4, and the second inserts 323 are used to be inserted into the third slot 41 of the side wall of the bridge system to limit and fix it.

[0070] When the splicing ends of the first splicing box 1 and the second splicing box 2 of the rotating splicing box and the connecting head 3 are spliced ​​using the plug-in structure of embodiment 2, the structure of the connecting head 3 is as follows: Fig. 9 As shown: a first plug 321 extends outwardly from both ends of the splicing end of the first plug block 32 facing away from the first splicing box 1 or the second splicing box 2. At the same time, a second plug 323 extends toward the splicing piece 4 from both ends of the splicing end of the first plug block 32 of the connector 3 facing away from the first splicing box 1 or the second splicing box 2.
