A type of aluminum alloy housing busbar trunking

Abstract

This utility model relates to the field of wiring device technology and discloses an aluminum alloy busbar trunking, including a first aluminum alloy busbar trunking. This utility model, through the design of a hollow block, a first ratchet plate, a second ratchet plate, an extension rod, and a first spring, allows the operator to directly insert the second ratchet plate (located below the connector box) into the hollow block, engaging the first and second ratchet plates. When the connector box contacts the first aluminum alloy busbar trunking, the teeth of the first and second ratchet plates prevent them from moving upwards, ensuring the connection between the connector box and the first aluminum alloy busbar trunking remains secure. Furthermore, the extension rod allows the operator to directly pull the extension rod, disengaging the first ratchet plate from the second ratchet plate, thus enabling the operator to directly disassemble the connector box.

Description

Technical Field

[0001] This utility model relates to the field of wiring device technology, and more specifically, to an aluminum alloy housing busbar trunking. Background Technology

[0002] Busbar trunking is a high-current power transmission system that replaces traditional cables. It consists of a metal shell, conductor bars, insulation materials, and connecting components. Its aluminum alloy shell has both heat dissipation and electromagnetic shielding functions. The conductor bars are treated with electrolytic copper and silver plating to reduce contact resistance. The modular design allows for power to be drawn from the plug-in box at any time. The rated current covers the range of 250A to 6300A. It is suitable for dense power supply scenarios such as industrial plants and data centers, and is a high-efficiency power transmission solution for modern power distribution systems.

[0003] When laying power systems, operators often use busbar trunking to ensure safety and stability under high current conditions. Although existing busbar trunking has basic power supply functions, bolts are generally used to fix the plug-in boxes near the busbar trunking when installing them. However, bolt fixing is cumbersome and inconvenient for installing and disassembling the plug-in boxes. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an aluminum alloy housing busbar trunking, which has the advantage of easy disassembly and assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aluminum alloy busbar trunking, comprising a first aluminum alloy busbar trunking, a plug-in box movably connected to the upper surface of the first aluminum alloy busbar trunking, hollow blocks fixedly connected to the outer surfaces of both sides of the first aluminum alloy busbar trunking, the upper surface of the hollow blocks movably connected to the lower surface of the plug-in box, a first ratchet plate movably connected to the inner surface of the hollow blocks, an extension handle fixedly connected to the lower surface of the first ratchet plate, and an extension rod fixedly connected to the front surface of the first ratchet plate. The front end of the extension rod passes through the hollow block and extends to the front side of the hollow block. The outer surface of the extension rod is movably sleeved with the inner surface of the hollow block. A first spring located inside the hollow block is movably sleeved on the outer surface of the extension rod. The front end of the first spring is fixedly connected to the inner surface of the hollow block. The rear end of the first spring is fixedly connected to the front surface of the first ratchet plate. A second ratchet plate located behind the first ratchet plate is movably connected to the outer surface of the first ratchet plate. The upper surface of the second ratchet plate is fixedly connected to the lower surface of the insertion box.

[0006] As a preferred technical solution of this utility model, positioning sleeves are fixedly connected to both the front and rear sides of the right surface of the first aluminum alloy busbar trough, and an insert block is movably sleeved on the inner surface of the positioning sleeve. The right end of the insert block is fixedly connected to the second aluminum alloy busbar trough.

[0007] As a preferred embodiment of this utility model, a mounting box is fixedly connected to the right surface of the No. 1 aluminum alloy busbar trough, and hinge blocks are movably connected to both the upper and lower sides of the inner surface of the mounting box. There are four hinge blocks, and the four hinge blocks are of the same size.

[0008] As a preferred embodiment of this utility model, the inner surfaces of the four hinge blocks are movably fitted with guide rods, and the upper and lower ends of the guide rods are respectively fixedly connected to the upper and lower sides of the inner surface of the mounting box.

[0009] As a preferred embodiment of this utility model, the outer surfaces of the four hinge blocks are all fixedly connected with insert rods. The other end of each insert rod passes through the positioning sleeve and the insert block in sequence and extends into the interior of the insert block. The outer surface of each insert rod is movably sleeved with the positioning sleeve and the inner surface of the insert block. The four hinge blocks are grouped in pairs. The inner surfaces of each group of hinge blocks are fixedly connected with a second spring located inside the mounting box.

[0010] As a preferred embodiment of this utility model, each of the four hinged blocks has a connecting rod hinged to its right surface, and a moving block is hinged to the other end of the connecting rod, and a limit rod is hinged to the other end of the moving block.

[0011] As a preferred embodiment of this utility model, the number of mounting boxes is two, and threaded rods are movably sleeved on the inner surfaces of both mounting boxes. Limiting rods located below the threaded rods are fixedly sleeved on the inner surfaces of both mounting boxes. The outer surface of the threaded rods and the inner surface of the moving block are threadedly sleeved, and the outer surface of the limiting rods and the inner surface of the moving block are movably sleeved.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting a hollow block, a first ratchet plate, a second ratchet plate, an extension rod, and a first spring, allows the operator to directly insert the second ratchet plate below the connector box into the hollow block, making the first and second ratchet plates engage. When the connector box contacts the first aluminum alloy busbar, the teeth of the first and second ratchet plates prevent the connector box and the second ratchet plate from moving upwards, ensuring that the connector box and the first aluminum alloy busbar will not loosen. The extension rod design allows the operator to directly pull the extension rod, causing the first ratchet plate to disengage from the second ratchet plate, thus allowing the operator to directly disassemble the connector box.

[0013] 2. This utility model, by setting a positioning sleeve, insert block, hinge block, insert rod, and moving block, allows the moving block to move left and right under the drive of the threaded rod when the operator rotates the threaded rod. As the moving block moves, the connecting rod starts to rotate, and at the same time, the other end of the connecting rod drives the hinge block as a whole, thereby causing the insert rod to gradually insert into the inner surface of the insert block. Finally, the insert block and the No. 2 aluminum alloy busbar trunking as a whole are fixed on the right side of the No. 1 aluminum alloy busbar trunking as a whole by the insert rod, avoiding the problem that the operator needs to repeatedly use instruments to perform orientation calibration when installing two parallel No. 1 aluminum alloy busbar trunkings.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 6As shown, this utility model provides an aluminum alloy busbar trunking system, including a first aluminum alloy busbar trunking system 1. A plug-in box 2 is movably connected to the upper surface of the first aluminum alloy busbar trunking system 1. Hollow blocks 3 are fixedly connected to the outer surfaces of both sides of the first aluminum alloy busbar trunking system 1. The upper surface of the hollow blocks 3 is movably connected to the lower surface of the plug-in box 2. A first ratchet plate 4 is movably connected to the inner surface of the hollow blocks 3. An extension handle 8 is fixedly connected to the lower surface of the first ratchet plate 4. An extension rod 6 is fixedly connected to the front surface of the first ratchet plate 4. The extension rod 6 has a front... The extension rod 6 passes through the hollow block 3 and extends to the front side of the hollow block 3. The outer surface of the extension rod 6 is movably sleeved with the inner surface of the hollow block 3. The outer surface of the extension rod 6 is movably sleeved with a first spring 7 located inside the hollow block 3. The front end of the first spring 7 is fixedly connected to the inner surface of the hollow block 3. The rear end of the first spring 7 is fixedly connected to the front surface of the first ratchet plate 4. The outer surface of the first ratchet plate 4 is movably connected with a second ratchet plate 5 located behind the first ratchet plate 4. The upper surface of the second ratchet plate 5 is fixedly connected to the lower surface of the insertion box 2.

[0018] Spring 7 will not be compressed due to normal vibrations in the working environment. When the operator uses a tool to move the extension handle 8 forward as a whole, causing the ratchet plate 4 to disengage from the ratchet plate 5, the lock of the ratchet plate 4 on the ratchet plate 5 and the connector box 2 as a whole will be released.

[0019] Among them, the front and rear sides of the right surface of the No. 1 aluminum alloy busbar trough 1 are fixedly connected with positioning sleeves 9, the inner surface of the positioning sleeve 9 is movably sleeved with a plug 10, and the right end of the plug 10 is fixedly connected to the No. 2 aluminum alloy busbar trough 11.

[0020] The design of the positioning sleeve 9 and the insertion block 10 serves to assist personnel in installation and positioning.

[0021] Among them, the right surface of the No. 1 aluminum alloy busbar trough 1 is fixedly connected to the mounting box 12, and the upper and lower sides of the inner surface of the mounting box 12 are movably connected to the hinge blocks 14. There are four hinge blocks 14, and the four hinge blocks 14 are the same size.

[0022] The design of the inner surface of the mounting box 12 and the hinge block 14 allows the hinge block 14 to move along the inner surface of the mounting box 12.

[0023] Among them, the inner surfaces of the four hinge blocks 14 are movably fitted with guide rods 13, and the upper and lower ends of the guide rods 13 are fixedly connected to the upper and lower sides of the inner surface of the mounting box 12, respectively.

[0024] The design of the guide rod 13 ensures the stability of the two hinge blocks 14 during movement.

[0025] Each of the four hinge blocks 14 has a fixedly connected insert rod 15 on its outer surface. The other end of the insert rod 15 passes through the positioning sleeve 9 and the insert block 10 in sequence and extends into the interior of the insert block 10. The outer surface of the insert rod 15 is movably connected to the positioning sleeve 9 and the inner surface of the insert block 10 respectively. Each of the four hinge blocks 14 is in pairs. The inner surface of each pair of hinge blocks 14 is fixedly connected to a second spring 16 located inside the mounting box 12.

[0026] The design of the insertion rod 15 ensures that when the insertion rod 15 is sleeved on the inner surface of the insertion block 10, the position of the insertion block 10 and the No. 2 aluminum alloy busbar trough 11 will be fixed by the combined action of the positioning sleeve 9 and the insertion rod 15.

[0027] Each of the four hinge blocks 14 has a connecting rod 17 hinged to its right surface. The other end of the connecting rod 17 is hinged to a moving block 18, and the other end of the moving block 18 is hinged to a limit rod 19.

[0028] The movement of the limit rod 19 will cause the moving block 18 to start rotating, and the rotation of the moving block 18 will drive the hinge block 14, thereby causing the hinge block 14 to start moving.

[0029] The number of mounting boxes 12 is two. The inner surfaces of the two mounting boxes 12 are movably fitted with threaded rods 20. The inner surfaces of the two mounting boxes 12 are fixedly fitted with limiting rods 19 located below the threaded rods 20. The outer surface of the threaded rods 20 and the inner surface of the moving block 18 are threadedly fitted. The outer surface of the limiting rods 19 and the inner surface of the moving block 18 are movably fitted.

[0030] The thread of the threaded rod 20 is a self-locking thread, which prevents the moving block 18 from moving due to external vibration.

[0031] Working principle and usage process of this utility model: When the operator needs to connect aluminum alloy busbar 1 and aluminum alloy busbar 11 in their unpowered state, the operator inserts the plug 10 into the positioning sleeve 9 and then rotates the threaded rod 20 until the operator can no longer rotate it. During this process, the moving block 18 will move left and right under the drive of the threaded rod 20. At this time, the connecting rod 17 will rotate with the movement of the moving block 18, and the other end of the connecting rod 17 will drive the hinge block 14 and the plug 15, thereby causing the plug 15 to be gradually inserted into the inner surface of the plug 10. Finally, when the plug 10 and the aluminum alloy busbar 11 are fixed to the right side of the aluminum alloy busbar 1, the connection of aluminum alloy busbar 1 and aluminum alloy busbar 11 is completed.

[0032] When the operator needs to install the plug box 2 into the No. 1 aluminum alloy busbar trough 1, the operator first exposes the interface of the No. 1 aluminum alloy busbar trough 1, then aligns the plug box 2 with the interface of the No. 1 aluminum alloy busbar trough 1, and then the operator moves the plug box 2 downwards. During this process, the No. 2 ratchet plate 5 will directly insert into the hollow block 3, so that the No. 1 ratchet plate 4 and the No. 2 ratchet plate 5 will mesh with each other until the No. 1 aluminum alloy busbar trough 1 and the plug box 2 are in contact. At this time, the plug box 2 will be fixed by the No. 1 ratchet plate 4 and the No. 2 ratchet plate 5. When the operator needs to remove the plug box 2, the operator first stops the power supply, and then pulls the extension handle 8 to disengage the No. 1 ratchet plate 4 from the No. 2 ratchet plate 5. At this time, the fixing of the plug box 2 will be released, allowing the operator to remove the plug box 2 directly.
