Description

Technical Field

[0001] The utility model relates to a fire-resistant bus duct, in particular to a fire-resistant bus duct with a detachable shell. Background Art

[0002] Bus ducts are used to replace wires and cables. They are often used in situations where excessive current is required. Bus ducts are enclosed metal devices made of copper and aluminum busbars, used to distribute high power to various components in a distributed system. They are increasingly replacing wires and cables in indoor low-voltage power transmission trunk projects.

[0003] The shell of the existing bus duct is generally connected by a bolt structure, and the various side panels and cover plates are connected by bolts. This connection method can support the heavy conductive copper bars inside the bus duct.

[0004] However, when the internal conductive copper bar of the bus duct fails or the mica insulation inside is damaged and requires repair, the cover and side panels are generally removed one by one using a wrench. This disassembly method is relatively cumbersome and can delay repairs in emergencies. Therefore, the existing bus duct housing installation method has certain limitations. Utility Model Content

[0005] The purpose of the present utility model is to provide a fire-resistant bus duct with a detachable shell to solve the limitation problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A fire-resistant bus duct with a detachable shell includes an upper cover plate and a lower end plate, which form the basic structure of the bus duct. A connecting frame is provided between the upper cover plate and the lower end plate, and a disassembly mechanism is provided on both sides of the connecting frame.

[0008] The disassembly mechanism includes a side plate, which is engaged with the structure on the connecting frame when pushed between the upper cover plate and the lower end plate, thereby engaging the side plate with both sides of the connecting frame;

[0009] Limiting strips for the side plates are also provided on both sides of the connection frame.

[0010] A fire-resistant bus duct with a detachable shell as described above: first limit plates are provided on both sides of the connecting frame, and the first limit plates are also distributed on the upper and lower sides of the connecting frame. Slide bars are provided on both sides of the connecting frame, and the slide bars are slidably connected to the limit blocks. A first vertical rod is provided on the limit blocks, and a circular through groove is opened on the first limit plate. The first vertical rod slides with the first limit plate.

[0011] In the fire-resistant bus duct with a detachable shell as described above, a first spring is sleeved on the surface of the first vertical rod, the top of the first spring abuts against the first limiting plate, and the bottom of the first spring abuts against the limiting block.

[0012] A fire-resistant bus duct with a detachable shell as described above: the disassembly mechanism also includes an extrusion block and an extrusion plate, the extrusion block is arranged on the front and rear sides of the side plate, the extrusion plate is arranged between the extrusion blocks, and the extrusion block is arranged at one end close to the limit block to form an inclined surface adapted to the limit block.

[0013] A fire-resistant bus duct with a detachable shell as described above: second limit plates are provided near the middle of both sides of the connecting frame, a second vertical rod is provided on the second limit plate, the top of the second vertical rod is connected to a hinge seat, a second spring is sleeved on the surface of the second vertical rod, the top of the second spring abuts against the hinge seat, and the bottom of the second spring abuts against the second limit plate.

[0014] As described above, in a fire-resistant bus duct with a detachable shell, a second connecting rod is rotatably connected to the hinge seat, and one end of the second connecting rod facing away from the hinge seat is rotatably connected to the extrusion plate.

[0015] As described above, in a fire-resistant bus duct with a detachable shell, a first connecting rod is rotatably provided on the limit block, and a button is rotatably provided on the end of the first connecting rod away from the limit block.

[0016] In the fire-resistant bus duct with a detachable shell as described above, the disassembly mechanism and the structure on the connection frame are symmetrically arranged at the four corners of the connection frame.

[0017] Compared with the prior art, the present invention has the following advantages: the present invention changes the conventional bolt installation structure by designing a disassembly mechanism. When the side panels need to be installed, the extrusion blocks on the side panels only need to be pushed inwards to quickly snap them in, thus solving the problems of troublesome and time-consuming installation.

[0018] The utility model is also designed with a detachable function. When disassembly is required, you only need to press the button inward to separate the extrusion block and the limit block on the side panel, so that it can be quickly disassembled. At the same time, a second spring is designed to push the side panel in the opposite direction through the second connecting rod, making it more labor-saving when disassembling the side panel.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] See also Figure 1-Figure 7 As an embodiment of the present invention, a fire-resistant bus duct with a detachable shell includes an upper cover plate 1 and a lower end plate 2. The upper cover plate 1 and the lower end plate 2 constitute the basic structure of the bus duct. A connecting frame 3 is provided between the upper cover plate 1 and the lower end plate 2. Disassembly mechanisms are provided on both sides of the connecting frame 3:

[0029] The disassembly mechanism includes a side plate 4, which engages with the structure on the connecting frame 3 when pushed between the upper cover plate 1 and the lower end plate 2, thereby engaging the side plate 4 on both sides of the connecting frame 3;

[0030] Limiting bars for the side plates 4 are also provided on both sides of the connecting frame 3 .

[0031] In this embodiment, the basic structure of the bus duct is formed by the upper cover plate 1 and the lower end plate 2, and mica insulation and conductive copper bars are arranged inside. For the bus duct structure with a detachable shell, a disassembly mechanism is provided on both sides of the connection frame 3 for installation and disassembly.

[0032] When the side panels 4 need to be installed, push the side panels 4 toward one side of the connecting frame 3 on both sides of the connecting frame 3, so that the disassembly mechanism on the side panels 4 is engaged with the structure on the connecting frame 3, and the side panels 4 can be quickly installed on the connecting frame 3, that is, on both sides of the upper cover plate 1 and the lower end plate 2.

[0033] As a further solution of the present invention, first limit plates 10 are provided on both sides of the connecting frame 3, and the first limit plates 10 are also distributed on the upper and lower sides of the connecting frame 3. Slide bars are provided on both sides of the connecting frame 3, and the slide bars are slidably connected to the limit blocks 9. A first vertical rod 8 is provided on the limit blocks 9, and a circular through groove is opened on the first limit plate 10. The first vertical rod 8 slides with the first limit plate 10.

[0034] In this embodiment, the structure on the connecting frame 3 in the above embodiment is that a first limit plate 10 is installed on the connecting frame 3, and sliding bars are installed on both sides of the connecting frame 3. A limit block 9 is also slidably provided at one end of the sliding bar, so the limit block 9 is slidably matched with the connecting frame 3, so that the limit block 9 can only slide up and down on both sides of the connecting frame 3.

[0035] As a further solution of the present invention, a first spring 7 is sleeved on the surface of the first vertical rod 8 , the top of the first spring 7 abuts against the first limiting plate 10 , and the bottom of the first spring 7 abuts against the limiting block 9 .

[0036] In this embodiment, combined with the previous embodiment, the limit block 9 can only slide up and down on both sides of the connecting frame 3. When the limit block 9 moves toward the first limit plate 10, it will squeeze the first spring 7 between itself and the first limit plate 10. After the first spring 7 is compressed, the position of the limit block 9 will also go up.

[0037] As a further solution of the present invention, the disassembly mechanism also includes an extrusion block 5 and an extrusion plate 6. The extrusion block 5 is arranged on the front and rear sides of the side plate 4, and the extrusion plate 6 is arranged between the extrusion blocks 5. The end of the extrusion block 5 close to the limit block 9 is arranged to be an inclined surface adapted to the limit block 9.

[0038] In this embodiment, when the side panel 4 needs to be installed, the limiting block 9 is squeezed by the squeezing block 5 on the side panel 4 , and a squeezing plate 6 is also installed on the side panel 4 at the same time.

[0039] As a further solution of the present invention, a second limiting plate 13 is provided on both sides of the connecting frame 3 near the middle, and a second vertical rod 15 is provided on the second limiting plate 13. The top of the second vertical rod 15 is connected to the hinge seat 16, and the surface of the second vertical rod 15 is sleeved with a second spring 14. The top of the second spring 14 abuts against the hinge seat 16, and the bottom of the second spring 14 abuts against the second limiting plate 13.

[0040] In this embodiment, a second limiting plate 13 is mounted on the connecting frame 3 , a second vertical rod 15 is mounted on the second limiting plate 13 , and a hinge seat 16 is mounted on the second vertical rod 15 .

[0041] As a further solution of the present invention, a second connecting rod 17 is rotatably connected to the hinge seat 16 , and one end of the second connecting rod 17 facing away from the hinge seat 16 is rotatably connected to the extrusion plate 6 .

[0042] In this embodiment, combined with the previous embodiment, when the extrusion plate 6 follows the side plate 4 to be squeezed inward, the extrusion plate 6 will squeeze the hinge seat 16 through the second connecting rod 17, so that the second spring 14 between the second limiting plate 13 and the hinge seat 16 is compressed, thereby storing elastic potential energy.

[0043] As a further solution of the present invention, a first connecting rod 11 is rotatably provided on the limit block 9 , and a button 12 is rotatably provided on one end of the first connecting rod 11 away from the limit block 9 .

[0044] In this embodiment, when the side panel 4 needs to be removed, the button 12 can be pressed inward, and the button 12 will push the limit block 9 to the upper and lower positions through the first connecting rod 11, so that the extrusion block 5 on the side panel 4 can be disengaged from the limit block 9, thereby quickly pulling the side panel 4 out from the inside of the limit block 9.

[0045] As a further solution of the present invention, the disassembly mechanism and the structure on the connecting frame 3 are symmetrically arranged at the four corners of the connecting frame 3 .

[0046] In this embodiment, disassembly mechanisms are provided at all four corners, so that the side panels 4 are evenly stressed during installation and removal, and the installation and removal are smooth.

[0047] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
