[0040] The transmission mechanism 6 includes a trigger post 61, a connecting rod assembly 65, and a sliding plate 63. The connecting rod assembly 65 is located between the trigger post 61 and the sliding plate 63. The trigger post 61 is slidably connected to the inside of the bridge frame 2, and a spring 62 is provided at the bottom of the trigger post 61. A stop block 64 is fixedly connected to the side of the sliding plate 63 away from the connecting rod assembly 65. The stop block 64 cooperates with the outward expansion block 7.

[0041] Both the top cover 1 and the cable tray 2 have a U-shaped cross section.

[0042] In further embodiments, the linkage assembly 65 comprises linkage one 651 and linkage two 652, linkage three 653 and linkage four 654, and linkage five 655 and linkage six 656 which are connected to each other by rotating connection, one end of linkage one 651 is connected to the inner wall of sliding groove 22 by rotating connection, one end of linkage two 652 is connected to the lower part of trigger column two 61 by rotating connection.

[0043] In the embodiments, when trigger column two 61 moves downward, one end of linkage two 652 moves downward, thereby the whole linkage assembly 65 starts to expand outward, thereby the plug-in mechanism 4 is pushed out from the inside of sliding groove 22, at this time, the top end of trigger column two 61 is flush with trigger column one 44.

[0044] In further embodiments, one end of linkage two 652 away from trigger column two 61 is connected to linkage three 653 and linkage six 656 by rotating connection from near to far, one end of linkage one 651 away from trigger column two 61 is connected to linkage four 654 and linkage five 655 by rotating connection from near to far.

[0045] In the embodiments, the linkage assembly 65 is a linkage telescopic mechanism in the prior art.

[0046] In further embodiments, one end of linkage five 655 is connected to one side of sliding plate 63 by rotating connection, one end of linkage six 656 is connected to one side of sliding plate 63 by sliding connection.

[0047] In the embodiments, when trigger column two 61 and trigger column one 44 are at the same height, further pressing cannot move the plug-in mechanism 4, but at this time, sliding plate 63 compresses spring one 46, thereby trigger column two 61 and trigger column one 44 can continue to move downward, during the moving process, abutting block 64 makes outer expansion plug 7 pop out from the periphery of bridge 2, thereby the outer expansion plug 7 can be inserted into the inside of inner butt joint groove 11.

[0048] In further embodiments, limiting rod 45 penetrates sliding plate 63, spring one 46 is arranged on the periphery of limiting rod 45, one end of abutting block 42 is fixedly connected with clamping block 43 and trigger column one 44.

[0049] In the embodiments, the upper end of clamping block 43 is connected with abutting block 42, the lower end of trigger column one 44 is connected with abutting block 42, when trigger column one 44 moves downward, clamping block 43 also moves downward, the inner wall of plug-in groove 21 is in L-shaped, thereby abutting plate 5 can slide up and down in the plug-in groove 21, and clamping block 43 can be clamped after moving downward.

[0050] In further embodiments, the inner side wall of top cover 1 is provided with inner butt joint groove 11, elastic member one 12 is arranged in the inner butt joint groove 11.

[0051] In the embodiment, the top cover 1 is provided with a plug-in hole at the plug-in position of the positioning plug 3, the plug-in hole is communicated with the inner butt joint groove 11, and the opening size of the inner butt joint groove 11 is greater than that of the outer expansion plug 7, so that the outer expansion plug 7 can still be plugged in the inner butt joint groove 11 during the process of extending out of the bridge 2.

[0052] In a further embodiment, the positioning plug 3 penetrates the outer expansion plug 7, and the lower portion of the connecting plate 5 is provided with an elastic member two 51.

[0053] In the embodiment, when the outer expansion plug 7 is plugged in the inner butt joint groove 11, the elastic member one 12 is pressed; the upper portion of the outer expansion plug 7 is provided with a hole, and the hole is aligned with the hole in the inner wall of the inner butt joint groove 11 after the outer expansion plug 7 presses the elastic member one 12, so that the positioning plug 3 can be plugged in to position the outer expansion plug 7; when the positioning plug 3 is pulled out, the elastic member one 12, the elastic member two 51, the spring one 46 and the spring two 62 start to rebound at the same time.

[0054] The working principle of the utility model is as follows:

[0055] When a plurality of bridges 2 need to be installed, the plurality of bridges 2 can be aligned first, then the top cover 1 is covered from the upper portion of the bridge 2, and the positioning plug 3 is plugged in, so that the installation and butt joint are completed;

[0056] In the process of covering the top cover 1 on the upper portion of the bridge 2, the trigger column two 61 is first lowered, so that the plug-in mechanism 4 is driven by the connecting rod assembly 65 to slide out of the inner portion of the sliding groove 22 and is plugged into the plug-in groove 21 of another bridge 2, and when the height of the trigger column two 61 is consistent with the height of the trigger column one 44, the plug-in mechanism 4 cannot be moved, at this time, continuously pressing the top cover 1 can make the trigger column two 61 and the trigger column one 44 move downward synchronously, the downward movement of the trigger column one 44 can make the clamping block 43 clamp on the upper portion of the connecting plate 5 through the connecting block 42, and the continuous downward movement of the trigger column two 61 can continuously drive the sliding plate 63 to move through the connecting rod assembly 65 to compress the spring one 46 and make the abutting block 64 push the outer expansion plug 7 to expand from the inner portion of the bridge 2, so that the outer expansion plug 7 is plugged in the inner butt joint groove 11, then the top cover 1 is kept pressed down, the positioning plug 3 penetrates the top cover 1 and the outer expansion plug 7, and the installation and fixation are completed.

[0057] When the bridge 2 at somewhere appears damage, the positioning plug 3 can be pulled out so that the expanded plug 7 is no longer limited, thus the elastic member one 12, the elastic member two 51, the spring one 46 and the spring two 62 will rebound at the same time, the rebound of the elastic member one 12 and the spring one 46 will make the expanded plug 7 no longer inserted in the inside of the inner butt joint groove 11, the rebound of the elastic member two 51 will make the clamping block 43 retract into the inside of the plug-in block 41, the rebound of the spring two 62 will make the trigger column two 61 move upward, thus the connecting rod assembly 65 is no longer unfolded, thus the plug-in mechanism 4 is pulled back to the inside of the sliding groove 22, so that it can be quickly disassembled.

[0058] According to the disclosure and teaching of the above description, the skilled in the art of the utility model can also change and modify the above-mentioned embodiments. Therefore, the utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the utility model should fall within the protection scope of the claims of the utility model. In addition, although some specific terms are used in the specification, these terms are only for convenience of description and do not constitute any limitation on the utility model.
