During installation, it is necessary to frequently replace or modify the fixing components, and even manually adjust the fixing position and force repeatedly, resulting in cumbersome and time-consuming installation procedures, which greatly reduces installation efficiency and increases labor costs and operational risks. In order to solve this technical problem, this utility model proposes a low-voltage switchgear with adjustable busbar fastening. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In the prior art, the busbar fixing devices of traditional low-voltage switchgear mostly adopt clamping structures of fixed size or single-specification mounting slots, which are difficult to adapt to different specifications of busbars. During installation, it is necessary to frequently replace or modify the fixing components, and even manually adjust the fixing position and force repeatedly, resulting in cumbersome and time-consuming installation procedures, which greatly reduces installation efficiency and increases labor costs and operational risks. In order to solve this technical problem, this utility model proposes a low-voltage switchgear with adjustable busbar fastening.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a low-voltage switchgear with adjustable busbar fastening, comprising a cabinet and a pair of mounting plates, wherein connecting frames are slidably connected to the outer ends of both ends of the mounting plates, a fixed base is fixedly connected to one outer wall of the connecting frame, a motor is fixedly connected to the outer wall of the fixed base, a bidirectional threaded rod is fixedly connected to the output end of the motor, connecting plates are threaded to both ends of the bidirectional threaded rod, a clamping plate is fixedly connected to the outer wall of the other end of each connecting plate, and an upper pressure plate is provided at the other end of each clamping plate.

[0008] Preferably, each of the clamping plates is rotatably connected to an adjusting screw, and each adjusting screw is threaded to a connecting block on its outer side wall, while the upper pressure plate is fixedly connected to the outer side wall of the connecting block.

[0009] Preferably, a bracket is fixedly connected to the outer wall of the other side of the connecting frame, a pin is slidably connected inside the bracket, and multiple insertion holes are opened inside the mounting plate, with the pin passing through the bracket and the connecting frame and extending into the insertion holes.

[0010] Preferably, a connecting ring is fixedly connected to the outer wall of the other end of the pin, and a spring is fixedly connected between the connecting ring and the bracket, and the spring is sleeved on the outer wall of the pin.

[0011] Preferably, the fixed base has a pair of sliding grooves II inside, the connecting plate is slidably connected in the sliding grooves II, the clamping plate has a sliding groove I inside, and the connecting block is slidably connected in the sliding groove I.

[0012] Preferably, both inner walls of the cabinet are fixedly connected to horizontal plates, and both ends of the mounting plate are slidably connected to the horizontal plates. The mounting plate is fixedly installed on the horizontal plates by bolts, and both sides of the cabinet are rotatably connected to openable and closed doors.

[0013] (III) Beneficial Effects

[0014] This utility model provides a low-voltage switchgear with adjustable busbar fastening. It has the following advantages:

[0015] (1) The fixed base provides support for components such as the motor and the bidirectional threaded rod. When the motor is started, the bidirectional threaded rod rotates in the fixed base, driving the connecting plate to move in the opposite direction along the second slide groove, so that the clamping plate fixes the left and right width of the busbar. When the adjusting screw is rotated, the connecting block drives the upper pressure plate to move downward along the first slide groove, pressing the busbar from above. This device solves the problem that the existing device is difficult to adapt to different sizes of busbars and is not firmly fixed. Through the linkage of various components, the fixing and disassembly of busbars of different sizes can be completed quickly, improving the installation efficiency, ensuring that the busbar is installed firmly, and meeting diverse work requirements.

[0016] (2) The mounting plate is fixed to the equipment with bolts, and the connecting frame is mounted on the mounting plate. The bracket is connected to the connecting frame. When it is necessary to adjust the spacing of the connecting frame, pull the pin outward. The connecting ring compresses the spring to make the pin disengage from the socket. At this time, the connecting frame can slide freely. After adjustment, release the pin. The spring rebounds and pushes the connecting ring to push the pin into the corresponding socket, realizing the quick fixation of the connecting frame. The fixed base provides stable support for the overall structure. This device solves the problems of inconvenient adjustment and poor adaptability of the existing equipment connecting frame, realizes quick and flexible adjustment, improves installation efficiency and environmental adaptability, and meets the needs of diverse working scenarios.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] Example 1: A low-voltage switchgear with adjustable busbar fastening includes a cabinet body 1 and a pair of mounting plates 4. Connecting brackets 6 are slidably connected to both ends of the mounting plates 4. A fixed base 12 is fixedly connected to one outer wall of the connecting bracket 6. A motor 13 is fixedly connected to the outer wall of the fixed base 12. A bidirectional threaded rod 14 is fixedly connected to the output end of the motor 13. Connecting plates 15 are threadedly connected to both ends of the bidirectional threaded rod 14. A clamping plate 16 is fixedly connected to the outer wall of the other end of each connecting plate 15. An upper pressure plate 19 is provided at the other end of each clamping plate 16. An adjusting screw 17 is rotatably connected inside each clamping plate 16. A connecting block 18 is threadedly connected to the outer wall of each adjusting screw 17. The upper pressure plate 19 is fixedly connected to the outer wall of the connecting block 18. A pair of sliding grooves 21 are provided inside the fixed base 12. The connecting plate 15 is slidably connected to the sliding grooves 21. A sliding groove 20 is provided inside the clamping plate 16, and the connecting block 18 is slidably connected to the sliding groove 20.

[0026] During busbar installation, the busbar is first placed stably between the two clamping plates 16. Then, the motor 13 is started, and the motor outputs power to drive the bidirectional threaded rod 14 to rotate within the fixed base 12. This causes the clamping plates 16 on the two connecting plates 15 to move in opposite directions. The connecting plates 15 are confined within the sliding groove 21. As the clamping plates 16 move towards each other, the left and right sides of the busbar are gradually clamped, completing the width-direction restriction and fixation. The clamping plates 16 are tightly fitted to the busbar. By rotating the adjusting screw 17, the connecting block 18 moves downward along the screw axis. The connecting block 18 is firmly connected to the upper pressure plate 19. Therefore, as the connecting block moves downward, the upper pressure plate 19 also moves downward, fixing the busbar in the front-to-back direction. This device can quickly adapt to busbars of different specifications and sizes, greatly improving the efficiency of busbar installation, reducing manual operation time and labor intensity, and also reducing safety hazards caused by improper installation, providing a reliable guarantee for the stable operation of the power system.

[0027] Example 2: The difference between this example and Example 1 is that, in this example, a bracket 7 is fixedly connected to the outer wall of the other side of the connecting frame 6, and a pin 8 is slidably connected inside the bracket 7. Multiple insertion holes 11 are opened inside the mounting plate 4, and the pin 8 passes through the bracket 7 and the connecting frame 6 and extends into the insertion hole 11. A connecting ring 10 is fixedly connected to the outer wall of the other end of the pin 8, and a spring 9 is fixedly connected between the connecting ring 10 and the bracket 7. The spring 9 is sleeved on the outer wall of the pin 8. Horizontal plates 3 are fixedly connected to both walls inside the cabinet 1. The two ends of the mounting plate 4 are slidably connected to the horizontal plates 3 respectively. At the same time, the mounting plate 4 is fixedly installed on the horizontal plates 3 by bolts 5. Opening and closing doors 2 are rotatably connected to both sides of the cabinet 1.

[0028] After securing the mounting plate 4 to the horizontal plate 3 of the cabinet 1 using bolts 5, adjust the connecting bracket 6 according to the required busbar installation spacing. Pull the pin 8 outward; the pin will be pulled out of the socket 11. Simultaneously, the connecting ring 10 compresses the spring 9 between itself and the bracket 7, allowing the connecting bracket 6 to slide along the mounting plate 4. Once adjusted to the appropriate position, with the pin 8 aligned with the corresponding socket 11, release the pin. The spring 9 will return, pushing the connecting ring 10 and the pin 8 into the socket 11, quickly fixing the connecting bracket 6. This structure allows for flexible adjustment, adapting to various working scenarios and significantly improving installation efficiency.

[0029] Working principle: First, the mounting plate 4 is installed on the horizontal plate 3 inside the cabinet 1 using bolts 5. The connecting bracket 6 is adjusted according to the required spacing between the busbars. At this time, the external pin 8 is pulled out of the socket 11, and the connecting ring 10 compresses the spring 9 between itself and the bracket 7. The connecting bracket 6 is then pushed and slid along the mounting plate 4. After adjusting to the appropriate distance, the pin 8 will align with the socket 11. Releasing the pin 8, the spring 9's return pushes the connecting ring 10 and the pin 8 into the socket 11, thus quickly fixing the connecting bracket 6. This allows for better adaptation to different working environments and improves efficiency. To improve efficiency, after adjusting the spacing on both sides, the busbar is placed between the two clamping plates 16. The motor 13 is started, which drives the bidirectional threaded rod 14 to rotate within the fixed base 12. The rotation of the fixed base 12 causes the clamping plates 16 on the connecting plate 15 to move in the opposite direction, thus limiting and fixing the left and right width of the busbar. The connecting plate 15 is also limited within the slide groove 21. After the left and right sides are fixed, the adjusting screw 17 is rotated, causing the connecting block 18 to move downwards, which in turn causes the upper pressure plate 19 to move downwards, thereby pressing down on the busbar and ensuring that the busbar will not loosen. Through their cooperation, the quick installation and disassembly of busbars of different sizes are achieved, improving work efficiency.
