Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a busbar support structure for a power distribution cabinet with adjustable dimensions. Background Technology

[0002] A distribution cabinet busbar is a metal conductor used to connect different electrical components (such as switches, circuit breakers, contactors, etc.) and transmit current within a distribution cabinet or distribution panel. It plays a role in the distribution and transmission of electrical energy and is an important component of the power system.

[0003] Current busbar systems suffer from two main problems: First, they have low fixing efficiency, are cumbersome to install and dismantle, and are typically installed via direct connection, leading to easily tangled and messy wiring, making later maintenance difficult. Second, the inability to adjust the position of the busbars makes the installation process complex, and the lack of effective protection and limiting functions when the busbars detach increases operational risks and maintenance difficulty. Therefore, this utility model proposes an adjustable-size distribution cabinet busbar support structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve two main problems existing in the current busbar system: First, the fixing efficiency is low, the installation and disassembly process is cumbersome, and the busbars are usually installed by direct connection, which makes the lines easy to become messy and tangled, and difficult to maintain and repair later. Second, since the position of the busbar cannot be adjusted, the installation process is complicated, and there is a lack of effective protection and limiting function when the busbar falls off, which increases the operational risk and maintenance difficulty. Therefore, an adjustable-size distribution cabinet busbar support structure is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable-size distribution cabinet busbar support structure includes a cabinet body, a cabinet door rotatably connected to the front side of the cabinet body via a hinge, and a mounting plate fixedly installed on the rear side of the cabinet body. The adjustable-size distribution cabinet busbar support structure also includes:

[0007] An adjustment mechanism is located on the top of the mounting plate and is used to adjust the position of the busbar.

[0008] A positioning mechanism is located at the bottom of the adjustment mechanism and is used to facilitate the positioning of busbars of different diameters.

[0009] As a preferred embodiment of this utility model, the adjustment mechanism includes: a sliding plate, a U-shaped frame, a sliding rod, a pull ring, a toothed plate, a rack and pinion, and a spring;

[0010] The sliding plate is slidably mounted on the top of the mounting plate. The top of the sliding plate is fixedly connected to the U-shaped frame. An opening is provided on the top of the sliding plate at the bottom of the inner cavity of the U-shaped frame. A sliding hole is provided on the top of the U-shaped frame. The inner cavity of the sliding hole is slidably connected to the surface of the sliding rod. The top of the sliding rod is fixedly connected to the pull ring. The bottom of the sliding rod passes through the inner cavity of the opening and is fixedly connected to the toothed plate. The front side of the mounting plate is fixedly connected to the rack. The top of the rack meshes with the toothed plate. A spring is movably sleeved on the surface of the sliding rod.

[0011] As a preferred embodiment of this utility model, the positioning mechanism includes: a positioning box, a knob, a lead screw, a threaded sleeve, a transmission plate, a push plate, a positioning plate, and a clamping block;

[0012] The positioning box is fixedly installed on the front side of the bottom of the mounting plate. The knob is movably located at the bottom of the positioning box. The top of the knob is fixedly connected to the lead screw. The top of the lead screw passes through the bottom of the positioning box and is rotatably connected to the top of the inner cavity of the positioning box through a rotating shaft. The top of the surface of the lead screw is movably connected to the inner cavity of the threaded sleeve. Both sides of the threaded sleeve are fixedly connected to the transmission plate. The opposite sides of the two transmission plates are fixedly connected to the push plate. The top and bottom of the push plate are slidably connected to the inner cavity of the positioning box. The front side of the push plate is fixedly connected to the positioning plate. There are two positioning plates. The front and rear sides of the opposite sides of the two positioning plates are fixedly connected to the clamping block.

[0013] As a preferred embodiment of this utility model, the top of the mounting plate is provided with a sliding groove, and the bottom of the sliding plate is provided with a sliding rail, with the sliding groove and the sliding rail cooperating.

[0014] As a preferred embodiment of this utility model, guide grooves are provided at the top and bottom of the positioning box cavity, and guide rails are provided at the top and bottom of the push plate, with the guide grooves and guide rails cooperating.

[0016] As a preferred embodiment of this utility model, a positioning hole is provided at the bottom of the positioning box, and the inner cavity of the positioning hole is rotatably connected to the surface of the lead screw through a rotating shaft.

[0017] Beneficial effects:

[0018] 1. When the busbar position needs to be adjusted, the user can use the pull ring to move the slide bar, so that the toothed plate and the rack disengage. At this time, the slide plate can move the U-shaped frame freely, thereby flexibly adjusting the installation position of the busbar and avoiding the tangling of the lines. When the position is adjusted to a suitable position, the pull ring is released, and the spring pushes the toothed plate and the rack to re-engage, thereby fixing the slide plate and ensuring that the busbar remains stable during operation and is not easy to fall off, which improves the installation efficiency and the convenience of later maintenance.

[0019] 2. When installing busbars of different diameters, the user can turn the knob to rotate the lead screw, which drives the threaded sleeve to move the transmission plate and push plate, so that the positioning plate drives the clamping block to clamp and fix the busbar. This structure can adapt to busbars of different sizes, enhance versatility, and at the same time keep the busbars neatly arranged to avoid mutual interference, improve the adaptability and reliability of installation, and reduce operational risks.

[0020] In this invention, the combined use of the adjustment mechanism and the positioning mechanism can adapt to busbars of different sizes, enhancing versatility, while maintaining the busbars in a neat arrangement to avoid mutual interference, thus improving the adaptability and reliability of installation and reducing operational risks.

When the busbar position needs to be adjusted, the user can use the pull ring 7 to move the slide bar 6, causing the toothed plate 8 and the rack 9 to disengage. At this time, the sliding plate 4 can move the U-shaped frame 5 freely, thereby flexibly adjusting the installation position of the busbar and avoiding the tangling of the lines. After adjusting to the appropriate position, the pull ring 7 is released, and the spring 10 pushes the toothed plate 8 and the rack 9 to re-engage, thereby fixing the sliding plate 4 and ensuring that the busbar remains stable during operation and is not easy to fall off, thus improving installation efficiency and the convenience of later maintenance.

[0033] The positioning mechanism includes: positioning box 11, knob 12, lead screw 13, threaded sleeve 14, transmission plate 15, push plate 16, positioning plate 17, clamping block 18;

[0034] The positioning box 11 is fixedly installed on the front side of the bottom of the mounting plate 3. The knob 12 is movably disposed at the bottom of the positioning box 11. The top of the knob 12 is fixedly connected to the lead screw 13.

The top surface of the lead screw 13 is movably connected to the inner cavity of the threaded sleeve 14. Both sides of the threaded sleeve 14 are fixedly connected to the transmission plate 15. The opposite sides of the two transmission plates 15 are fixedly connected to the push plate 16. The top and bottom of the push plate 16 are slidably connected to the inner cavity of the positioning box 11. The front side of the push plate 16... The positioning plates 17 are fixedly connected to each other. There are two positioning plates 17. The front and rear sides of the two positioning plates 17 are fixedly connected to the clamping blocks 18 on opposite sides. When installing busbars of different diameters, the user can turn the knob 12 to drive the lead screw 13 to rotate, which drives the threaded sleeve 14 to push the transmission plate 15 and the push plate 16 to move, so that the positioning plates 17 drive the clamping blocks 18 to clamp and fix the busbars. This structure can adapt to busbars of different sizes, enhance versatility, keep the busbars neatly arranged, avoid mutual interference, improve the adaptability and reliability of installation, and reduce operational risks.

[0035] To improve the stability of the sliding plate 4 during movement, a groove is provided on the top of the mounting plate 3 and a slide rail is provided on the bottom of the sliding plate 4.

The inner cavity of the positioning hole is rotatably connected to the surface of the lead screw 13 through a rotating shaft, thereby improving the stability of the lead screw 13 during rotation.

[0039] The working principle of this utility model is as follows: When installing the busbar, the busbar is placed in the positioning box 11. Rotating the knob 12 drives the lead screw 13 to rotate, which drives the threaded sleeve 14 to move. This pushes the transmission plate 15 and the push plate 16 to slide in the positioning box 11, so that the positioning plate 17 drives the clamping block 18 to clamp and fix the busbar, thereby adapting to busbars of different diameters and ensuring their stable installation. When it is necessary to adjust the position of the busbar, the user pulls the pull ring 7 to move the slide rod 6 in the U-shaped frame 5, compressing the spring 10 and disengaging the toothed plate 8 from the rack 9. At this time, the sliding plate 4 can slide along the top of the mounting plate 3. After moving the U-shaped frame 5 to the target position, the pull ring 7 is released, and the spring 10 pushes the toothed plate 8 and the rack 9 to re-engage, thereby fixing the sliding plate 4 and completing the adjustment of the busbar position.
