[0028] Example:

[0029] like Figure 1 and Figure 2 As shown, the utility model proposes a sealing structure of a bus duct, including two groups of bus duct bodies 1, and multiple groups of joints 2 arranged on one side of the two groups of bus duct bodies 1 close to each other. The bus duct bodies 1 and the joints 2 are both existing structures and will not be described in detail here.

[0030] Specifically, the sealing structure further includes a sealing assembly 3 installed between two groups of bus duct bodies 1 to ensure that the joints 2 are dustproof and waterproof. The sealing assembly 3 includes a sealing cylinder 31, a fixing plate 32, and a rubber ring 33. The rubber ring 33 is arranged between the two groups of bus duct bodies 1 and sleeved on the outside of the multiple groups of joints 2. The rubber ring 33 is used to prevent water and dust from contacting the multiple groups of joints 2 inside. The two groups of fixing plates 32 are respectively installed at one end of the bus duct body 1 close to the sealing cylinder 31. The rubber ring 33 is installed on one side of the fixing plate 32 close to the sealing cylinder 31, and is used to drive the fixing plate 32 close to the sealing cylinder 31 when the two groups of bus duct bodies 1 are close to each other, so as to squeeze the rubber ring 33 to enhance the sealing performance and further prevent the entry of dust and water. The sealing assembly 3 also includes a fixing block 34, a bolt 35, and a connecting seat 36. The two groups of fixing blocks 34 are symmetrically arranged on both sides of the sealing cylinder 31 and are fixedly connected to the sealing cylinder 31. The position of the fixing block 34 is fixed. The bolts 35 are slidably connected in the fixing block 34, and the two groups of connecting seats 36 symmetrically arranged on both sides of the bus duct body 1 are respectively threadedly connected to the two groups of bolts 35, so that the bolts 35 can move along their own length direction when rotating, so that when the bolts 35 move in the direction close to the bus duct body 1, the sealing tube 31 can be driven to approach the bus duct body 1 through the fixing block 34, so that the sealing tube 31 squeezes the rubber ring 33 to enhance the sealing.

[0031] For further information, see Figure 3 and Figure 4The sealing structure also includes a connection mechanism 4 provided in the sealing assembly 3 for connecting multiple groups of connectors 2. The connection mechanism 4 includes a pressing plate 41, a connecting plate 42, and a supporting plate 43. The pressing plate 41, the connecting plate 42, and the supporting plate 43 are all provided inside the sealing cylinder 31. Multiple groups of connecting plates 42 are equidistantly provided between the pressing plate 41 and the supporting plate 43. The connecting plate 42 is also provided between two adjacent groups of connectors 2. The side of the connecting plate 42 close to the connector 2 is a conductive material, and the conductive materials on both sides of the connecting plate 42 are insulated from each other. The connectors 2 at one end of the two groups of bus duct bodies 1 can achieve the connection of the two groups of bus duct bodies 1 after being in close contact with the connecting plate 42. At the same time, the two adjacent groups of connectors 2 are insulated from each other to prevent short circuits. The connection mechanism 4 also includes a plurality of groups of limit plates 44, which are arranged on both sides of the pressing plate 41, the connecting plate 42 and the supporting plate 43. The limit plates 44 are fixedly connected to the inner wall of the sealing cylinder 31. The position of the limit plates 44 is fixed, and is used to limit the pressing plate 41 and the connecting plate 42 when they move, so that the pressing plate 41 and the connecting plate 42 move smoothly. The connection mechanism 4 also includes a threaded rod 45, a positioning seat 46, a rotating rod 47, and a sealing ring 48. The threaded rod 45 is rotatably connected to the inner wall of the sealing cylinder 31, and the threaded rod 45 keeps rotating in place. The threaded rod 45 penetrates the pressing plate 41, the connecting plate 42 and the supporting plate 43. The pressing plate 41 is threadedly connected to the threaded rod 45, and the threaded rod 45 is used to drive the pressing plate 41 to move along the length direction of the threaded rod 45 when the threaded rod 45 rotates. The connecting plate 42 and the supporting plate 43 are both slidably connected with the threaded rod 45. When the connecting plate 42 slides on the threaded rod 45, there is a certain friction force, which is used to fix the position of the connecting plate 42, and does not hinder the rotation of the threaded rod 45. When the threaded rod 45 drives the pressing plate 41 to move, the pressing plate 41 squeezes the multiple groups of joints 2 and the connecting plate 42, so that the multiple groups of connecting plates 42 slide on the threaded rod 45 and are limited by the limiting plate 44. The positioning seat 46 installed on the inner wall of the sealing cylinder 31 is rotatably connected with the threaded rod 45. The positioning seat 46 is arranged on the side of the supporting plate 43 away from the connecting plate 42, so that the threaded rod 45 can rotate in place. The rotating rod 47 that runs through one side of the sealing cylinder 31 is fixedly connected to one end of the threaded rod 45, so as to facilitate the rotation of the threaded rod 45 outside the sealing cylinder 31. The sealing ring 48 is arranged at the position where the rotating rod 47 runs through the sealing cylinder 31, which is used to strengthen the sealing and prevent the joint 2 from being affected by moisture.

[0032] In this embodiment, the sealing cylinder 31 is firstly sleeved on one end of a group of bus duct bodies 1, and at the same time, the multiple groups of connectors 2 at one end of the bus duct body 1 are inserted between two adjacent groups of connecting plates 42, and then the connectors 2 at one end of another group of bus duct bodies 1 are inserted between two adjacent groups of connecting plates 42 in the sealing cylinder 31. At this time, a wrench is used to rotate the multiple groups of bolts 35, so that the bolts 35 are threadedly connected with the connecting seat 36, and the connecting seat 36 moves toward the direction close to the bus duct body 1 and drives the sealing cylinder 31 to move through the fixing block 34. At this time, the sealing cylinder 31 and the bus duct body 1 are close to each other, so that the sealing cylinder 31 and the fixing plate 32 squeeze the rubber ring 33, thereby increasing the sealing effect of the sealing cylinder 31. Finally, a wrench is used to rotate the rotating rod 47, and the rotating rod 47 drives the threaded rod 45 to rotate in place when rotating. At the same time, the threaded rod 45 drives the pressing plate 41 threadedly connected thereto to start moving and approach the supporting plate 43. At this time, the pressing plate 41 moves under the limiting action of the limiting plate 44, and squeezes the multiple sets of joints 2 to deform, and at the same time drives the multiple sets of fixing plates 32 to slide synchronously under the limiting action of the limiting plate 44 and approach the supporting plate 43. At this time, the positioning seat 46 can support the supporting plate 43. At this time, the multiple sets of joints 2 are tightly fitted with the connecting plate 42, so that the joints 2 at the ends of the two sets of bus duct bodies 1 are correspondingly connected, and the two sets of bus duct bodies 1 are connected.

[0033] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
