[0026] Further, one end of the cross beam 13 is provided with an assembly groove 131 capable of sliding the cover plate 14.

[0027] Further, the cover plate 14 is symmetrically fixed and connected with the connecting plate 143 on both sides of the bottom end face away from the first mounting seat 141, the outer side of the connecting plate 143 is fixedly connected with the guide plate 144, and the inner side wall of the cross beam 13 is provided with a guide groove 132 capable of displacing the guide plate 144. Through the cooperation of the guide groove 132 and the guide plate 144, the cover plate 14 is always connected with the cross beam 13 during sliding, and the guide plate 144 can limit the cover plate 14.

[0028] Further, the cover plate 14 is provided with a butt plate 145 extending along the length direction of the cover plate 14 away from the first mounting seat 141, and the inner side wall of the side plate 12 is provided with a butt groove 124 capable of inserting the butt plate 145. The butt groove 124 is provided with a clamping plate 125, and the butt plate 145 is provided with a clamping groove 146 capable of inserting the clamping plate 125. Through the cooperation of the butt plate 145 and the butt groove 124 and the cooperation of the clamping plate 125 and the clamping groove 146, the cover plate 14 is tightly connected with the side plate 12 when the cover plate 14 is connected with the side plate 12, thereby improving the sealing performance of the connection between the cover plate 14 and the side plate 12.

[0029] Further, the supporting column 122 is provided with an insertion hole 126 penetrating the sliding groove 123, and the insertion hole 126 is slidably connected with an insertion rod 127. One end of the insertion rod 127 extends to the outside of the insertion hole 126 and is provided with a driving disc 128. A tension spring 129 is arranged on the insertion rod 127 outside the insertion hole 126, one end of the tension spring 129 is fixedly connected with the supporting column 122, and the other end of the tension spring 129 is fixedly connected with the driving disc 128.

[0030] Further, the sliding rod 142 is provided with a first fixing hole 147 and a second fixing hole 148 penetrating the sliding rod 142. The first fixing hole 147 is capable of inserting the insertion rod 127 in the closed state of the cover plate 14, and the second fixing hole 148 is capable of inserting the insertion rod 127 in the open state of the cover plate 14. When the bus duct is normally working, the cover plate 14 is in the closed state, the first fixing hole 147 is in communication with the insertion hole 126 and is locked by the insertion rod 127, thereby locking the sliding rod 142 and the supporting column 122, and to a certain extent, limiting the sliding of the cover plate 14.

The supporting column 122 and the sliding rod 142 can support the cover plate 14 protruding out of the side plate 12 and to a certain extent, limit the sliding of the cover plate 14.

[0031] Further, the cross beam 13 is rotationally connected with a clamping hook 133 at one side close to the first mounting base 141, and the cover plate 14 is provided with a clamping column 149 corresponding to the clamping hook 133 at one side close to the first mounting base 141, and the clamping column 149 is used for clamping the clamping hook 133 after rotation, so that the cover plate 14 and the cross beam 13 can be further locked, and the cover plate 14 is stably connected between the two cross beams 13.

[0032] The working principle of the utility model:

[0033] When the bus duct fails, the maintenance personnel rotates the clamping hook 133, so that the clamping hook 133 is separated from the connection with the clamping column 149, thereby releasing the locking of the cover plate 14 and the cross beam 13, then the driving disc 128 is stretched outward, the driving disc 128 drives the plug-in rod 127 to displace synchronously until the front end of the plug-in rod 127 is completely separated from the first fixed hole 147 on the sliding rod 142, thereby releasing the locking of the sliding rod 142 and the supporting column 122, and the stretching spring 129 is stretched and elastically deformed, the cover plate 14 is pushed again, so that the cover plate 14 slides in the assembly groove 131 on the cross beam 13, and the sliding rod 142 slides in the supporting column 122 synchronously with the sliding of the cover plate 14, the guide plate 144 on the cover plate 14 also slides in the guide groove 132 on the cross beam 13 synchronously until the guide plate 144 abuts against the side plate 12, at this time, the second fixed hole 148 on the sliding rod 142 is in communication with the plug-in hole 126 on the supporting column 122, finally the driving disc 128 is loosened, the stretching spring 129 rebounds under the elastic action and drives the plug-in rod 127 to pass through the second fixed hole 148 and the plug-in hole 126 in turn, thereby locking the sliding rod 142 and the supporting column 122, and the supporting column 122 and the sliding rod 142 can support the cover plate 14 protruding out of the side plate 12, at this time, the cover plate 14 is opened, and the maintenance personnel can maintain the bus duct inside from the top of the bus duct shell 1, after the maintenance work is completed, the cover plate 14 is reset and locked by reversing the above operation.

[0034] In the description of the utility model, it should be explained that, unless there is definite provision and limitation, the terms "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to specific circumstances.

[0035] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model.
