Example 1

As shown in fig. 1-4, the utility model provides a joint structure based on subway traction equipment electric box, including the electric box 1 of rectangle, the equal fixed connection connecting plate 11 in electric box 1 both sides, connecting plate 11 sets up in electric box 1 lower part, the connecting pipe 2 of one of them connecting plate 11 one side fixed connection rectangle, the connecting block 3 of another connecting plate 11 one side fixed connection rectangle, connecting pipe 2 corresponds the setting with connecting block 3, the connecting pipe 2 of electric box 1 one side is connected with the mutual grafting cooperation of connecting block 3 of adjacent electric box 1 one side. Connecting pipe 2 all sets up the middle part at connecting plate 11 with connecting block 3 to make can be more even transmit power after electric box 1 is connected through connecting pipe 2 and connecting block 3 with adjacent electric box 1. Be equipped with stop device on connecting block 3, stop device includes inserted

block

6, and 3 upsides of connecting block are equipped with

perpendicular hole

61, and 6 sliding connection of inserted block is equipped with spring 62 in perpendicular hole 61, and spring 62 fixed connection is between the hole bottom of perpendicular hole 61 and inserted

block

6, and 2 upsides of connecting pipe are equipped with jack 63, and inserted block 6 corresponds the setting with

jack

63, 6 upsides fixed connection arc 64 of inserted block. In the free state, the insert 6 with the upper arc 64 projects out of the upper side of the connecting piece 3 under the force of the spring 62. In the process that the connection block 3 on one side of the electrical box 1 is inserted into the connection pipe 2 on one side of the adjacent electrical box 1, the arc-shaped block 64 is attached to the lower side of the inner wall of the connection pipe 2 on one side of the adjacent electrical box 1, and the arc-shaped block 64 presses the insertion block 6 to move downward along the vertical hole 61. When the arc block 64 moves to a position coinciding with the insertion hole 63, the insertion block 6 pushes the arc block 64 upwards out of the upper side of the connection pipe 2 from the insertion hole 63 under the action of the spring 62, so that the position of the connection block 3 in the connection pipe 2 is fixed, and the connection pipe 2 on one side of the electrical box 1 and the connection block 3 on one side of the adjacent electrical box 1 can be stably connected.
