DETAILED DESCRIPTION
[0022] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.
[0023] like Figure 1-Figure 4As shown, the bus duct with good protection performance provided by the present embodiment includes a bus duct body 1, and a first connecting shell 2 and a second connecting shell 3 are respectively arranged at both ends of the bus duct body 1. The first connecting shell 2 and the second connecting shell 3 are both slidingly connected to the bus duct body 1, and a first flange 4 is arranged on the outer side of the first connecting shell 2, and a second flange 5 is arranged on the outer side of the second connecting shell 3. It can provide all-round protection for the connection of the bus duct body 1, and can realize precise positioning and rapid docking, thereby enhancing the stability of the connection, facilitating future disassembly and maintenance work, and reducing long-term maintenance costs.
[0024] In this embodiment, if Figure 2 As shown, two slide rails 6 are arranged at intervals on the upper and lower sides of both ends of the bus duct body 1, a first slide groove 7 for use with the slide rail 6 is arranged on the inner side of the first connecting shell 2, and a second slide groove 8 for use with the slide rail 6 is arranged on the inner side of the second connecting shell 3. The sliding connection is achieved by means of slide rails and slide grooves, with a simple structure and easy operation.
[0025] In this embodiment, if Figure 3 and Figure 4 As shown, the first slide groove 7 and the second slide groove 8 are both structures with closed inner sides and open outer sides, which limit the sliding distance of the first connecting shell 2 and the second connecting shell 3 to prevent movement after connection.
[0026] In this embodiment, if Figure 3 and Figure 4 As shown, an annular groove 9 is provided on the outer side of the first flange 4, an annular protrusion 10 is provided on the outer side of the second flange 5, and a sealing ring 11 is provided in the annular groove 9, which can enhance the connection stability, provide a sealing effect, and prevent dust from directly entering.
[0027] In this embodiment, if Figure 1 As shown, a first heat dissipation hole 12 is provided on the first connecting shell 2, and a second heat dissipation hole 13 is provided on the second connecting shell 3. Both the first heat dissipation hole 12 and the second heat dissipation hole 13 are inclined structures with high inside and low outside, which can prevent foreign objects from falling directly into the connection of the bus duct while dissipating heat.
[0028] In summary, in the present embodiment, the first connection shell 2 and the second connection shell 3 provided in the present embodiment provide all-round protection for the connection of the bus duct body 1 by sliding the first connection shell 2 and the second connection shell 3 outward and connecting respectively after the two bus duct bodies 1 are connected. This design enables the bus duct to be docked quickly and accurately, which is convenient for future maintenance and disassembly. At the same time, through the docking and fixation of the first flange 4 and the second flange 5, the connection is more firm, which effectively prevents the loose connection due to vibration or external force during operation, and improves the overall protection performance of the bus duct; the first heat dissipation hole 12 and the second heat dissipation hole 13 provided can prevent external foreign matter from falling directly into the connection of the bus duct through the inclined setting of the inner high and the outer low, while not affecting the air circulation, maintaining a good balance between protection and heat dissipation.
