[0001] The utility model relates to the technical field of bus ducts, in particular to a connecting structure for tubular bus ducts. Background Art

[0002] The tubular bus duct adopts a tubular structure and is made of metal materials (such as copper, aluminum, etc.). It has good electrical conductivity and heat dissipation performance. The internal conductors are usually arranged in a "pin" shape, with a reasonable structure, a low skin effect coefficient, a small AC resistance, so the electrical loss is small, and it is energy-efficient. In addition, the tubular bus duct adopts a sealed and shielded insulation method, with strong electrical insulation and is not affected by environmental factors such as high-altitude condensation, marine salt spray, and dust, and is suitable for use in any geographical environment.

[0003] Existing bus ducts are often fixedly connected by bolts. Bolt connection increases the working intensity of workers and is inconvenient for connecting bus ducts. At the same time, a protection mechanism is often not provided at the connection between bus ducts, which leads to the connection of bus ducts being easily polluted and corroded by the external environment, resulting in damage. Therefore, a bus duct connection protection structure is needed. Therefore, the utility model proposes a connecting structure for tubular bus ducts to solve the above problems. Content of the Utility Model

[0005] To achieve the purpose of the utility model, the utility model is realized through the following technical solutions: A connecting structure for tubular bus ducts includes a main frame plate, a support rod, and a sub-frame plate. Support rods are symmetrically arranged on both sides of the bottom of the main frame plate. A sub-frame plate is arranged above the main frame plate. Protection mechanisms are symmetrically arranged on both sides of the main frame plate and the sub-frame plate. A connecting cylinder is arranged inside the protection mechanism, and connecting bolts are symmetrically and detachably connected to both sides of the connecting cylinder.

[0006] Further improvement lies in that: The protection mechanism includes a rotating arm, a rotating rod, a movable rod, a limiting rod, a strip-shaped groove, and a locking bolt.

A movable rod is arranged on the outer side of the rotating rod. A limiting rod is fixedly connected to one end of the movable rod. A strip-shaped groove is arranged inside the movable rod. A locking bolt is fixedly connected to the outer side of the rotating rod.

[0008] A further improvement is that threaded rods are fixedly connected to both sides of the bottom of the sub-frame plate, and grooves are symmetrically provided on both sides of the main frame plate. The bottom end of the threaded rod passes through the bottom of the groove and is threadedly connected to a nut. A stop block is provided at the bottom end of the threaded rod.

[0012] The beneficial effects of this utility model are as follows: The connecting cylinder is placed in the arc-shaped grooves on both sides of the main frame plate or the auxiliary frame plate. The rotating arm is rotated to cover the top of the connecting cylinder. The rotating rod on the left rotating arm is rotated to the right, thereby causing the movable rod on the rotating rod to sit on the top of the right rotating arm.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a connection structure for tubular busbar trunking, including a main frame plate 1, support rods 2, and a secondary frame plate 3. Support rods 2 are symmetrically arranged on both sides of the bottom of the main frame plate 1, and a secondary frame plate 3 is arranged above the main frame plate 1. Protective mechanisms are symmetrically arranged on both sides of the main frame plate 1 and the secondary frame plate 3. A connecting cylinder 5 is provided inside the protective mechanism. Connecting bolts 6 are symmetrically and detachably connected to both sides of the connecting cylinder 5. Two tubular busbar trunkings are respectively inserted into the two ends of the connecting cylinder 5, and one end of the two trunkings is connected to each other. The tubular busbar trunkings are clamped by screwing in the connecting bolts 6 to connect the two tubular busbar trunkings into one unit. Then, the connecting cylinder 5 together with the tubular busbar trunkings is placed into the interior of the protective mechanism. The protective mechanism isolates the connection point of the two tubular busbar trunkings from the outside world, thus protecting the connection point.

[0020] The protective mechanism includes a rotating arm 4, a rotating rod 7, a movable rod 8, a limiting rod 9, a strip groove 10, and a locking bolt 11. The main frame plate 1 and the auxiliary frame plate 3 are symmetrically hinged with rotating arms 4 on both sides. The outer side of the rotating arm 4 on the left side is hinged with a rotating rod 7. The outer side of the rotating rod 7 is provided with a movable rod 8. One end of the movable rod 8 is fixedly connected to a limiting rod 9. The movable rod 8 is provided with a strip groove 10 inside. The outer side of the rotating rod 7 is fixedly connected with a locking bolt 11.

[0021] One end of the locking bolt 11 passes through the interior of the strip groove 10 and is threaded with a nut. The outer side of the limiting rod 9 is fitted and connected to the top of the rotating arm 4 on the right side. A set of arc-shaped grooves are symmetrically provided on both sides of the main frame plate 1 and the auxiliary frame plate 3.

[0022] Place the connecting cylinder 5 into the arc-shaped grooves on both sides of the main frame plate 1 or the auxiliary frame plate 3. Rotate the rotating arm 4 to cover the top of the connecting cylinder 5. Rotate the rotating rod 7 on the left rotating arm 4 to the right, thereby causing the movable rod 8 on the rotating rod 7 to sit on the top of the right rotating arm 4. Then loosen the nut on the locking bolt 11. The movable rod 8 can slide on the outside of the rotating rod 7, causing the limiting rod 9 at the right end of the movable rod 8 to fit against the top of the right rotating arm 4. Finally, tighten the nut on the locking bolt 11 to fix the two rotating arms 4 into one unit. Then, the connecting cylinder 5 is fixed on the top of the auxiliary frame plate 3 and the main frame plate 1 through the rotating arm 4. At the same time, the rotating arm 4, the main frame plate 1, and the auxiliary frame plate 3 enclose the connecting cylinder 5, which plays a protective role at the connection of the two tubular busbar trunking.

[0023] Threaded rods 12 are fixedly connected to both sides of the bottom of the sub-frame plate 3. The main frame plate 1 has symmetrical grooves 13 on both sides. The bottom end of the threaded rod 12 passes through the bottom of the groove 13 and is threaded with a nut. The bottom end of the threaded rod 12 is provided with a stop block. The threaded rods 12 on both sides of the bottom of the sub-frame plate 3 are inserted into the grooves 13 on both sides of the main frame plate 1 until the stop block at the bottom end of the threaded rod 12 fits against the top of the groove 13. Then, the nut is tightened on the bottom end of the threaded rod 12. The nut and the stop block clamp the main frame plate 1 and the threaded rod 12 to fix the sub-frame plate 3 above the main frame plate 1, so that the connection structure can fix more tubular busbars.

[0024] The support rod 2 is equipped with a lifting mechanism inside. The top of the lifting mechanism is fixedly connected to the bottom of the main frame plate 1, and the bottom of the support rod 2 is fixedly connected to a drive box 14.

[0025] The lifting mechanism includes a lead screw sleeve 18, a lead screw 19, and a lifting rod 20. The bottom end of the lead screw sleeve 18 is fixedly connected to a first bevel gear 16. A second bevel gear 17 is rotatably connected to one side of the drive box 14. The outer walls of the first bevel gear 16 and the second bevel gear 17 mesh with each other. A knob 15 is provided on one side of the drive box 14. One end of the knob 15 is fixedly connected to one side of the second bevel gear 17. The knob 15 drives the second bevel gear 17 to rotate inside the drive box 14. The second bevel gear 17 meshes with the outer wall of the first bevel gear 16. The lead screw sleeve 18 is fixed to the first bevel gear 16. Therefore, rotating the knob 15 can drive the lead screw sleeve 18 to rotate inside the support rod 2.

[0026] The bottom of the support rod 2 is rotatably connected to a lead screw sleeve 18, and the lead screw 19 is internally threaded onto the lead screw sleeve 18. The top of the lead screw 19 is fixedly connected to a lifting rod 20. The outer wall of the lifting rod 20 is slidably connected to the inner wall of the support rod 2. The lead screw sleeve 18 and the lead screw 19 are threaded together, and the lead screw 19 and the lifting rod 20 are fixed as one unit. The support rod 2 restricts the movement trajectory of the lifting rod 20. While the lead screw sleeve 18 rotates in both directions, it can drive the lifting rod 20 to move up and down reciprocally through the lead screw 19. The top of the lifting rod 20 is connected to the bottom of the main frame plate 1 as one unit, which is used to drive the main frame plate 1 to move up and down, so as to facilitate the adjustment of the tubular busbar to a suitable height.

[0027] The tubular busbar trunking uses a connecting structure. The connecting cylinder 5 is placed in the arc-shaped grooves on both sides of the main frame plate 1 or the auxiliary frame plate 3. The rotating arm 4 is rotated to cover the top of the connecting cylinder 5. The rotating rod 7 on the left rotating arm 4 is rotated to the right, thereby causing the movable rod 8 on the rotating rod 7 to sit on the top of the right rotating arm 4. Then, the nut on the locking bolt 11 is loosened, and the movable rod 8 can slide on the outside of the rotating rod 7, causing the limiting rod 9 at the right end of the movable rod 8 to fit against the top of the right rotating arm 4. Finally, the nut on the locking bolt 11 is tightened to fix the two rotating arms 4 into one unit. The connecting cylinder 5 is then fixed on the top of the auxiliary frame plate 3 and the main frame plate 1 through the rotating arm 4. At the same time, the rotating arm 4, the main frame plate 1, and the auxiliary frame plate 3 enclose the connecting cylinder 5, which plays a protective role at the connection of the two tubular busbar trunkings.
