[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1-4, A fixing structure for a busbar trunking, comprising a busbar trunking body 1, a fixing base 2, a suspension rod 3 and a fixing device. At both ends of the top wall of the fixing base 2, the suspension rod 3 is fixedly installed. The busbar trunking body 1 and the fixing base 2 are connected by the fixing device. The fixing device includes a groove body 4, a bidirectional screw 5, a driving shaft 6, a slider 7, a moving frame 8, a pressing frame 9, a sleeve 10, a support rod 11 and a spring 12. A groove body 4 is opened at the top end of the fixing base 2. The bidirectional screw 5 is rotatably installed in the groove body 4. One end of the bidirectional screw 5 penetrates through the side wall of the groove body 4 and the driving shaft 6 is installed. The left and right ends of the bidirectional screw 5 are both threadedly installed with the slider 7. The top end of the slider 7 is fixedly installed with the moving frame 8. The inner bottom wall of the moving frame 8 is hingedly installed with the pressing frame 9. One end of the inner bottom wall of the moving frame 8 far from the hinge point is installed with the sleeve 10. The support rod 11 is slidably installed at the bottom end of the sleeve 10. The support rod 11 is fixedly connected to the top wall of the pressing frame 9. The outer walls of the sleeve 10 and the support rod 11 are sleeved with the spring 12. In this embodiment, when in use, first place the busbar trunking body 1 on the fixing base 2, and then manually rotate the driving shaft 6. The driving shaft 6 drives the bidirectional screw 5 to rotate in the groove body 4. When the bidirectional screw 5 rotates, the sliders 7 at its left and right ends will move in opposite directions due to the thread action. As the sliders 7 move, the moving frame 8 fixed to their top ends will also move accordingly. When the pressing frame 9 touches the top wall of the busbar trunking body 1, it will drive the pressing frame 9 to adjust its position. The top wall of the pressing frame 9 is fixedly connected to the support rod 11, so that the support rod 11 slides in the sleeve 10. When the support rod 11 slides in the sleeve 10, it will compress the spring 12 sleeved on the outer walls of the sleeve 10 and the support rod 11, generating a downward pressure. Under the pressure of the spring 12, when the two moving frames 8 touch the left and right side walls of the busbar trunking body 1, the pressing frame 9 will firmly press the busbar trunking body 1 and fix it on the fixing base 2. Through the above steps, a firm connection is achieved between the busbar trunking and the fixing base 2. The busbar trunking body 1 can be fixed by multiple groups of fixing devices. Finally, it is installed and fixed to the ceiling through the suspension rod 3. By adjusting the bidirectional screw 5, appropriate adjustment can be made according to the size of the busbar trunking body 1, which is applicable to busbar trunking bodies 1 of different sizes. When maintenance of the busbar trunking body 1 is required, the fixing device can be easily adjusted to facilitate the disassembly of the busbar trunking body 1 for inspection or repair.

[0025] Preferably, in this embodiment, the bottom corners of the corresponding ends of the two pressing frames 9 are designed with rounded corners. The rounded corner design can prevent sharp corners from scratching or wearing the busbar trunking body 1 and extend the service life of the busbar trunking body 1.

[0026] Preferably, in this embodiment, the lower pressure frame 9 is of U-shaped design. The U-shaped design can provide a larger contact area, which helps to improve the stability between the lower pressure frame 9 and the bus duct body 1 and reduce shaking.

[0027] Preferably, in this embodiment, the movable frame 8 is L-shaped. The L-shaped design can provide a larger supporting area, which helps to improve the stability between the movable frame 8 and the fixed base 2.

[0028] Preferably, in this embodiment, the groove body 4 is a rectangular groove with a regular shape, which can provide a precise guide path for the slider 7 to ensure that the slider 7 moves smoothly along the predetermined direction, which helps to improve the accuracy of the movement of the slider 7 and reduce deviation.

[0029] In actual use, in order to further facilitate the rotation of the drive shaft 6, in this embodiment, a knob 13 is installed at the end of the drive shaft 6. The knob 13 is larger than the diameter of the drive shaft 6 and can apply a larger torque during rotation, making the drive shaft 6 easier to rotate, so that the operator can easily hold and rotate the drive shaft 6 with his hands.

[0030] In actual use, in order to further improve the anti-slip property of the knob 13, in this embodiment, an anti-slip strip 14 is installed on the outer wall of the knob 13. The anti-slip strip 14 can increase the friction coefficient of the surface of the knob 13 and improve the anti-slip property of the knob 13.

[0031] In actual use, it is further facilitated to install at the target position. In this embodiment, a mounting seat 15 is installed at the top of the suspension rod 3, and a mounting hole 16 is opened on the mounting seat 15. A connecting piece 17 is movably installed in the mounting hole 16. The suspension rod 3 drives the mounting seat 15 to be moved to the ceiling, and the mounting seat 15 is fixed to the ceiling using appropriate connecting pieces 17 (such as screws, expansion bolts, etc.), ensuring that the mounting seat 15 is firmly fixed at the target position, and completing the hoisting installation of the bus duct body 1.
