[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 2 and Figure 3 , the utility model provides an embodiment: a novel adjustable bus duct, including a bus duct shell 1, a tooth plate 2 is fixedly connected to the bus duct shell 1, a connecting shell 3 is slidably connected to the bus duct shell 1, a gear 4 is rotatably connected to the connecting shell 3, an extension shell 5 is slidably connected to the connecting shell 3, a tooth plate 2 6 is fixedly connected to the extension shell 5, and the extension shell 5 is meshed with the tooth plate 2 and the tooth plate 2 6. One side of the outer wall of the connecting shell 3 is fixedly connected to a fixed shell 1 7, one side of the outer wall of the extension shell 5 is fixedly connected to a fixed shell 2 8, a connecting block 13 is fixedly connected to the top of the fixed shell 7, a limiting column 9 is slidably connected to the connecting block 13, the outer wall of the limiting column 9 is fixedly connected to a fixing plate 11, a spring 10 is fixedly connected to the top of the fixing plate 11, one end of the spring 10 is fixedly connected to the inside of the connecting block 13, a plurality of circular grooves 12 are opened inside the extension shell 5, a fixing component is provided on the top of the bus duct shell 1, and the fixing component is used to fix the bus duct shell 1;

[0033] Specifically, when using the new adjustable bus duct, first pull up the limit column 9. This action is to temporarily release the fixed limit of the extension shell 5. This operation allows the user to flexibly change the length of the bus duct according to actual installation or adjustment needs. After the limit column 9 is released, pull the fixed shell 1 7, and the pulling of the fixed shell 1 7 will directly act on the moving pulling gear 4. Since the gear 4 is tightly engaged with the tooth plate 1 2, the gear 4 will rotate accordingly. The rotation of the gear 4 transmits its power to the tooth plate 2 6, so that the extension shell 5 can move to the right. As the extension shell 5 moves, a part of it will gradually extend from the inside of the bus duct shell 1. This process allows the user to The user can adjust the length of the bus duct according to the actual wiring needs. This design not only improves the flexibility of installation, but also ensures the applicability in complex electrical wiring. When the length of the bus duct is adjusted to the ideal state, loosen the limit column 9. At this time, due to the elastic force of the spring 10, the limit column 9 will automatically slide into the inside of the circular groove 12. This action provides a limit for the extension shell 5 again, ensuring that in the subsequent use process, the extension shell 5 remains in the set position and will not move unnecessary due to external forces. This design detail reflects the emphasis on product stability and user operation safety, so that the bus duct can provide reliable and stable performance in various electrical installation occasions.

[0034] Reference Figure 1 and Figure 4 The fixing assembly includes a connecting column 14 and a fixing ring 15. The top of the connecting column 14 is fixedly connected to the inside of the fixing ring 15. The top of the bus duct housing 1 is fixedly connected to the bottom of the connecting column 14. The top of the fixing ring 15 is fixedly connected to a fixing block 16. One side of the outer wall of the fixing block 16 is rotatably connected to a hexagonal block 17. One side of the outer wall of the hexagonal block 17 is fixedly connected to a worm 18. The inside of the fixed block 16 is rotatably connected to a worm gear 19. The worm 18 is engaged with the worm gear 19. The top of the worm gear 19 is fixedly connected to a disc 20. The inside of the disc 20 is slidably connected to a sliding column 22. A curved groove 21 is opened inside the disc 20. The outer wall of the sliding column 22 is slidably connected to the inside of the curved groove 21. The outer wall of the sliding column 22 is fixedly connected to a transmission rod 23. One side of the outer wall of the transmission rod 23 is fixedly connected to an inner support block 24.

[0035] Specifically, in the process of installing the bus duct housing 1, first insert the top cylinder of the fixing block 16 into the reserved hole, then rotate the hexagonal block 17. This action will affect the worm 18 through the mechanical transmission mechanism. As the hexagonal block 17 rotates, the worm 18 starts to rotate, thereby driving the worm gear 19. After being subjected to force, the worm gear 19 will drive the disc 20 connected to it to rotate counterclockwise. During the rotation of the disc 20, the curved groove 21 on it interacts with the slide post 22, so that the slide post 22 moves along a specific trajectory under the guidance of the curved groove 21. The movement direction of the slide post 22 is away from the center of the disc 20. The movement of the slide post 22 transmits the force to the inner support block 24 through the transmission rod 23, and the inner support block 24 moves toward the inside of the reserved hole, thereby realizing internal support of the hole. Through this series of precise mechanical actions, the installation process is more efficient and convenient, reducing the operating steps and difficulty of the installer, so that the new adjustable bus duct can be firmly fixed in the appropriate position, ensuring the accuracy of the installation and the stability of the structure.

[0036] Working principle: When using the new adjustable bus duct, first pull the limit column 9 upward to release the limit on the extension shell 5, then pull the fixed shell 7 as needed. At this time, the movement of the fixed shell 7 pulls the gear 4 to move. Because the gear 4 and the tooth plate 2 are engaged, the gear 4 is forced to rotate, and the rotation of the gear 4 causes the tooth plate 2 6 to be forced to drive the extension shell 5 to move to the right. At this time, a part of the extension shell 5 extends from the inside of the bus duct shell 1 to adjust its length. After the adjustment is completed, release the limit column 9. At this time, the limit column 9 is pushed by the spring 10 to move forward. Insert the circular groove 12 and limit the extension shell 5 to prevent it from moving. When the bus duct housing 1 needs to be installed, the cylinder on the top of the fixing block 16 can be inserted into the reserved hole. At this time, the hexagonal block 17 is rotated, and the hexagonal block 17 drives the worm 18 to rotate, so that the worm wheel 19 is forced to drive the disc 20 to rotate counterclockwise. When the disc 20 rotates, with the cooperation of the curved groove 21, the sliding column 22 is forced to move in the direction away from the center of the disc 20, and the transmission rod 23 drives the inner support block 24 to support the reserved hole. At this time, the new adjustable bus duct can be fixed.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
