Technical Field

[0001] The utility model relates to the technical field of signal transmission, in particular to an automatic signal transmission busbar. Background Art

[0002] A signal transmission busbar is a kind of busbar, which is specially used for transmitting signals rather than directly transmitting electric energy. The busbar plays a role of collecting, distributing and transmitting electric energy in the power system, but the signal transmission busbar is mainly applied to fields such as communication systems and control systems to realize the reliable transmission of signal automation.

[0003] When laying out the signal transmission busbar, it generally needs to be used in combination with a busbar box. The busbar needs to be inserted into the cavity of the busbar box. However, during the laying process, the busbar already laid in the busbar box is easily pulled, and when pulled, the busbar may shift in the busbar box, which easily causes the busbar to become messy and is not conducive to the rapid laying of the busbar. Summary of the Utility Model

[0004] The utility model provides an automatic signal transmission busbar to solve the problem that during the laying process, the busbar already laid in the busbar box is easily pulled, and when pulled, the busbar may shift in the busbar box, which easily causes the busbar to become messy and is not conducive to the rapid laying of the busbar.

Three fixing blocks are evenly and fixedly connected to one side of the sleeve. The inner walls of adjacent two fixing blocks are fixedly connected to the same threaded cylinder. A threaded rod is threadedly connected to the inner wall of the threaded cylinder. An auxiliary block is arranged on the outer surface of the threaded rod. One side of the auxiliary block is fixedly connected to one side of the rectangular rod. A clamping plate is arranged on one side of the outer surface of the auxiliary block. An adjusting device is arranged between the sleeve and the protective sleeve.

[0006] The effects achieved by the above components are as follows: By providing two clamping plates, under the action of the threaded rod, rotating the threaded rod, the threaded rod will expand and contract inside the threaded cylinder. During the expansion and contraction process of the threaded rod, the rectangular rod connected to the auxiliary block will slide synchronously inside the sleeve, and the rectangular rod will drive the clamping plate to move synchronously until the two clamping plates completely clamp both sides of the outer surface of the busbar box, then it can prevent the busbar from shifting in the busbar box and is conducive to the rapid laying of the busbar.

[0007] Preferably, a bearing is fixedly connected to the outer surface of the threaded rod, and the outer surface of the bearing is fixedly connected to the inner wall of the auxiliary block.

[0016] The effect achieved by the above components is that by setting the extension bands and the threaded pin, the threaded pin is pushed to move on the inner walls of the two auxiliary grooves until the outer surface of the threaded pin abuts against the outer surface of the protective sleeve. Then, the two nuts are rotated respectively so that one side of the nuts abuts against one side of the extension bands, and thus the sleeve and the protective sleeve can be fixed, which is beneficial to preventing the sleeve and the clamping plate from shifting on the outer surface of the protective sleeve.

[0017] Preferably, sliding strips are fixedly connected to the outer surface of the protective sleeve, sliding grooves are formed on one side of the sleeve, and the outer surface of the sliding strip is slidably connected to the inner wall of the sliding groove.

[0018] The effects achieved by the above components are as follows: By providing a slider and a sliding groove, the slider can limit the sleeve, which is beneficial to preventing the sleeve from rotating on the outer surface of the protective sleeve and facilitating the rapid adjustment of the clamping plate.

[0029] Reference Figure 2 and Figure 3 As shown, the outer surface of the threaded rod 33 is fixedly connected to a bearing 36, and the outer surface of the bearing 36 is fixedly connected to the inner wall of the auxiliary block 34. By setting the bearing 36, the friction between the threaded rod 33 and the auxiliary block 34 can be reduced when the threaded rod 33 is rotated, making it easier to rotate the threaded rod 33; the ends of the two threaded rods 33 that are away from each other are fixedly connected to an operating block 37, and the outer surface of the operating block 37 is provided with a protrusion. By providing the operating block 37, rotating the operating block 37 can drive the threaded rod 33 to rotate. At the same time, the outer surface of the operating block 37 is provided with a protrusion, which can effectively increase the friction on the outer surface of the operating block 37, and has an anti-slip effect when the operating block 37 is rotated.

[0030] Reference Figure 2 and Figure 3 As shown, one side of the auxiliary block 34 is fixedly connected with a mounting block 38, and the mounting block 38 is fixedly connected to one side of the clamping plate 35 by bolts.

By setting the rubber plate 39 with grooves, the friction force of the clamping side of the clamping plate 35 can be increased, so that the two clamping plates 35 can be more tightly clamped on the outer surface of the bus duct.

[0031] Referring to Figure 2 and Figure 4 as shown, the adjusting device 4 includes two extension belts 41. An auxiliary groove 42 is formed on one side of the extension belt 41. The inner walls of the two auxiliary grooves 42 are inserted with the same threaded pin 43. Two nuts 44 are threadedly connected to the outer surface of the threaded pin 43. The two nuts 44 are respectively arranged on the opposite sides of the extension belt 41. By providing the extension belt 41 and the threaded pin 43, the threaded pin 43 is pushed to move on the inner walls of the two auxiliary grooves 42 until the outer surface of the threaded pin 43 abuts against the outer surface of the protective sleeve 2.

Round blocks 47 are arranged at both ends of the threaded pin 43. The outer diameter of the round block 47 is larger than the outer diameter of the threaded pin 43. By providing the two round blocks 47, the two ends of the threaded pin 43 can be respectively limited, which is beneficial to preventing the nut 44 from disengaging from the threaded pin 43 due to misoperation.

[0033] Working principle: After the bus bar is clamped in the bus bar box, the operating block 37 is rotated to drive the threaded rod 33 to rotate. The threaded rod 33 will expand and contract on the inner wall of the threaded barrel 32. During the expansion and contraction process of the threaded rod 33, the rectangular rod 311 connected to the auxiliary block 34 will slide synchronously on the inner wall of the sleeve 310. The rectangular rod 311 will drive the clamping plate 35 to move synchronously until the rubber plates 39 on one side of the two clamping plates 35 completely clamp both sides of the outer surface of the bus bar box, and thus the bus bar can be prevented from shifting in the bus bar box, facilitating the quick layout of the bus bar. When it is necessary to fix the sleeve 310 and the protective sleeve 2, the threaded pin 43 is pushed to move on the inner walls of the two auxiliary grooves 42 until the outer surface of the threaded pin 43 abuts against the outer surface of the protective sleeve 2. Then, the two nuts 44 are respectively rotated so that one side of the nut 44 abuts against one side of the extension belt 41. Then, under the limitation of the slide bar 45 and the chute 46, the sleeve 310 and the protective sleeve 2 can be fixed, which is beneficial to preventing the sleeve 310 and the clamping plate 35 from shifting on the outer surface of the protective sleeve 2.
