Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to an adjustable bus duct for installing electronic components. Background Art

[0002] A bus duct is a closed metal device composed of copper and aluminum bus bars, which is used to distribute relatively large power to each component of a decentralized system. It has increasingly replaced wire and cable in indoor low-voltage power transmission trunk line engineering projects.

[0003] Electronic components play roles of controlling, protecting, and regulating current in a power distribution system. For example, components such as resistors, capacitors, inductors, diodes, and transformers play roles of shunting, current limiting, energy storage, and voltage transformation in a circuit respectively. These components are reasonably arranged and connected through the bus duct to ensure the stable operation of the power system.

[0004] The lengths of existing bus ducts are basically fixed. Therefore, during actual installation, it is difficult to adjust according to actual installation requirements. If there are situations of being too large or too small during installation, it will affect the installation of the bus duct. For this reason, an adjustable bus duct for installing electronic components is proposed. Summary of the Utility Model

[0005] The utility model is proposed to solve the deficiencies existing in the prior art, and provides an adjustable bus duct for installing electronic components.

[0006] To achieve the above purpose, the utility model adopts the following technical solution: An adjustable bus duct for installing electronic components includes a main frame. There are multiple chambers inside the main frame. A sealing shell is fixedly embedded in the inner tops of the multiple chambers. A pushing component is installed between the sealing shell and the main frame. Multiple movable ends of the pushing component are fixedly connected with L-shaped plates, and the number of L-shaped plates is the same as the number of chambers. The L-shaped plates penetrate through the inner wall of the sealing shell and extend into the corresponding chambers, and the L-shaped plates are in sealing sliding connection with the sealing shell;

[0007] The bottoms of the multiple L-shaped plates are all fixedly connected with movable seats, and one side of the outer surface of each of the multiple movable seats is fixedly connected with a movable copper bar;

[0008] The outer surfaces of the multiple movable seats are symmetrically sleeved with movable sleeves, and the movable sleeves penetrate through the inner wall of the adjacent chamber and extend to the outside of the main frame, and the movable sleeves are in sealing sliding connection with the main frame. Fixed copper bars are fixedly connected inside the multiple movable sleeves. The outer surfaces of the fixed copper bars on the same side are jointly fixedly sleeved with an installation shell, and the installation shell is fixedly connected with the adjacent multiple movable sleeves;

[0009] On one side of the outer surface of the main frame, a C-shaped seat is fixedly installed. A bidirectional moving component is jointly installed between the C-shaped seat and the two mounting shells, and a driving component with a locking function is jointly installed between the bidirectional moving component and the C-shaped seat.

[0010] Furthermore, the pushing component includes a first handwheel, and the first handwheel is arranged on the outer side of the main frame. On one side of the outer surface of the first handwheel, a long screw rod is fixedly connected. The long screw rod penetrates through the outer wall of the main frame and extends into the interior of the sealing shell, and the long screw rod is rotatably connected to the main frame. A plurality of sliders are threadedly sleeved on the outer surface of the long screw rod, and the sliders are fixedly connected to the adjacent L-shaped plates. The setting of the first handwheel is beneficial to manually driving the first handwheel to rotate.

[0011] Furthermore, the bidirectional moving component includes a gear, and the gear is arranged inside the C-shaped seat. Two racks are symmetrically meshed and connected to the outer surface of the gear, and the racks are fixedly connected to the adjacent mounting shells, and the racks are slidably connected to the C-shaped seat. The C-shaped seat has a limiting effect on the racks, which can ensure the stability of the movement of the racks.

[0012] Furthermore, the driving component with a locking function includes a second handwheel. On one side of the outer surface of the second handwheel, a connecting shaft is fixedly connected. The connecting shaft penetrates through the C-shaped seat and is rotationally connected therewith in a limited manner, and the connecting shaft is fixedly connected to the gear. The setting of the second handwheel is beneficial to driving the connecting shaft to rotate, so as to drive the gear to rotate.

[0013] Furthermore, a hand-tightening screw penetrates through one side of the outer surface of the second handwheel, and the hand-tightening screw is threadedly connected to the second handwheel. The screw rod end of the hand-tightening screw is fixedly connected to a limiting rod. The setting of the hand-tightening screw is beneficial to driving the limiting rod to move.

[0014] Furthermore, a plurality of limiting holes are evenly formed on one side of the outer surface of the C-shaped seat, and the limiting holes are matched with the limiting rod. The plurality of limiting holes are arranged in a ring shape with the connecting shaft as the center. The cooperation between the limiting holes and the limiting rod has a limiting effect on the second handwheel.

[0015] Furthermore, on one side of the outer surface of each of the six movable sleeves, a blocking block is fixedly connected. The blocking block has a limiting effect and can prevent the movable sleeve from separating from the main frame.

[0016] The beneficial effects of the present utility model:

[0017] When the utility model is in use, for the adjustable busbar for installing electronic components, by setting the main frame, chamber, sealing shell, L-shaped plate, movable seat, movable copper bar, movable sleeve, fixed copper bar, installation shell, C-shaped seat, bidirectional moving component and driving part with locking function, during the actual installation process, the use length of the busbar can be adjusted as needed to meet the installation requirements and improve the overall practicability. At the same time, when adjusting, the fixed copper bar and the movable copper bar can be separated to avoid increasing wear and ensure the service life of the copper bar.
