Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, and specifically to a sealing structure for a switch cabinet. Background Technology

[0002] To improve the airtightness of the switchgear, in addition to strengthening the sealing measures at the cabinet's inlet and outlet points, the sealing at the connection between the cabinet and the cabinet door is also particularly important. Currently, most cabinets achieve a seal by installing a sealing ring on the door, ensuring it contacts the cabinet opening.

[0003] Chinese patent CN 222301138U discloses a sealing structure for a switchgear, including: a switchgear body for installation; and a sliding block, with a spring and a nut on the outer side of the sliding block, the nut located at the lower end of the spring. A fixing plate is fixed to the lower end of the sliding block, and a first sealing ring is connected to the lower end of the fixing plate. A first fixing block is fixed to the left side of the installation door. This sealing structure facilitates the fixing of the first sealing ring, preventing loosening and preventing moisture from entering the switchgear through the door and damaging electrical components. The connection structure ensures that the door can be stably locked while also being easily and quickly opened for convenient inspection and maintenance.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the first sealing ring is fixed by multiple sliding blocks, nuts and fixing plates set at equal angles. When replacing the sealing ring, the nuts need to be turned and the sliding blocks adjusted one by one. The disassembly and assembly operations are cumbersome. Especially when there are many sliding blocks, repeated disassembly and assembly can easily lead to installation errors and affect the sealing effect. Utility Model Content

[0020] Example 1

[0021] like Figures 1 to 4 As shown, the present invention proposes a sealing structure for a switch cabinet, comprising a switch cabinet body 1, a first limiting mechanism 8, a first sealing mechanism 11, and a second limiting mechanism; a cabinet door 7 is hinged to the switch cabinet body 1, and the other end of the cabinet door 7 is detachably connected to the switch cabinet body 1 via a latch. The latch is existing technology, and those skilled in the art can select a suitable latch to connect the cabinet door 7 to the switch cabinet body 1 according to actual installation needs, which will not be described in detail here; the first limiting mechanism 8 is installed on the inner side wall of the cabinet door 7; the first sealing mechanism 11 is inserted between the first limiting mechanism 8 and the cabinet door 7, and the first sealing mechanism 11 consists of a second sealing part 13. The first sealing part 12, which is connected to the second sealing part 13, and the support ring 15 constitute the first sealing part 12. A first clearance opening 14 is provided on the side wall of the first sealing part 12 away from the second sealing part 13. The support ring 15 is U-shaped and is embedded in the inner cavity of the first sealing part 12 through the first clearance opening 14. The support ring 15 is made of steel to improve the strength of the first sealing part 12. The second limiting mechanism is adjustablely installed on the cabinet door 7. The second limiting mechanism abuts against the open end of the first limiting mechanism 8 and the corresponding end of the first sealing mechanism 11 to limit the first sealing mechanism 11 and the first limiting mechanism 8.

[0022] Further, the first limiting mechanism 8 is in a C shape and is composed of a mounting part 9 and a plugging part 10. The mounting part 9 is mounted on the cabinet door 7. A plugging cavity is formed between the plugging part 10 and the cabinet door 7. The first sealing mechanism 11 is plugged into the plugging cavity, facilitating the quick disassembly and assembly of the first sealing mechanism 11.

[0023] Furthermore, the first sealing part 12 is plugged into the plugging cavity between the plugging part 10 and the cabinet door 7. The first sealing part 12 is in contact with both the plugging part 10 and the cabinet door 7. One end of the second sealing part 13, which is far away from the first sealing part 12, protrudes from one end of the plugging part 10 that is far away from the mounting part 9, enhancing the sealing performance at the closing position of the cabinet door 7 and the switchgear cabinet body 1.

[0024] Further, the first sealing part 12 is a fluororubber seat, and the second sealing part 13 is a fluororubber pad. Compared with traditional rubber, it improves the elastic stability within the temperature range of -40°C to 200°C, extends the service life, and facilitates the disassembly and assembly of the support ring 15 through the first relief opening 14 and the inner cavity of the first sealing part 12.

[0025] In the present utility model, the assembly of the first sealing mechanism 11 can be completed by passing the support ring 15 through the first relief opening 14 and pressing it into the inner cavity of the first sealing part 12. At this time, the first sealing part 12 has a certain strength under the support of the support ring 15. Insert the first sealing part 12 along the plugging cavity between the plugging part 10 and the cabinet door 7 until the advancing end of the first sealing mechanism 11 abuts against one end of the first limiting mechanism 8 that is far away from the open end. At this time, the first sealing part 12 is in contact between the plugging part 10 and the cabinet door 7, and the second sealing part 13 protrudes from the plugging part 10. Then, limit the first sealing mechanism 11 and the open end of the first limiting mechanism 8 through the second limiting mechanism. Rotate the cabinet door 7 to close it with the switchgear cabinet body 1, and connect the cabinet door 7 and the switchgear cabinet body 1 through a lock. At this time, the second sealing part 13 is pressed by the cabinet door 7 and abuts tightly against the edge of the open end of the switchgear cabinet body 1, enhancing the sealing performance. The settings of the second sealing part 13 and the first sealing part 12 extend the service life, and when the first sealing mechanism 11 needs to be disassembled, replaced, or maintained, only need to unlock the second limiting mechanism, slide the first sealing mechanism 11 along the first limiting mechanism 8 to the side and pull it out, then it can be replaced. It has high sealing performance and is more convenient and fast for disassembly, replacement, and maintenance.

[0026] Embodiment 2

[0027] As Figure 1 and Figure 2As shown, the sealing structure of the switch cabinet proposed in this utility model, compared with the first embodiment, further includes a second limiting mechanism. The second limiting mechanism includes a limiting plate 18 and a plug rod 20. One end of the limiting plate 18 is hinged to the cabinet door 7, and the other end is provided with a slot 19. The side wall of the limiting plate 18 abuts against the side end of the first limiting mechanism 8 and the first sealing mechanism 11. The plug rod 20 is elastically connected to the cabinet door 7, and the plug end of the plug rod 20 is detachably connected to the slot 19.

[0028] Furthermore, a first mounting base 16 and a second mounting base 17 are provided on the inner wall of the cabinet door 7 and near the open end of the first limiting mechanism 8. The limiting plate 18 is connected to the first mounting base 16 via a hinge. The insertion rod 20 is slidably inserted into the second mounting base 17. A spring 21 is sleeved on the insertion rod 20. One end of the spring 21 is connected to the top of the insertion rod 20, and the other end is connected to the second mounting base 17.

[0029] In an optional embodiment, in the initial state, the limiting plate 18 rotates downward along the first mounting base 16 away from the cabinet door 7. After the first sealing mechanism 11 is inserted between the first limiting mechanism 8 and the cabinet door 7, the limiting plate 18 is rotated upward along the first mounting base 16, and the insertion rod 20 is moved upward along the second mounting base 17, so that 201 is stretched. After the side wall of the limiting plate 18 and the side wall of the first limiting mechanism 8 and the first sealing mechanism 11 abut against the side end of the first limiting mechanism 8 and the first sealing mechanism 11, the insertion rod 20 is released. Under the restoring force of the spring 21, the insertion end of the insertion rod 20 is inserted into the slot 19 on the limiting plate 18, thereby limiting the limiting plate 18 and the cabinet door 7, thus limiting the first sealing mechanism 11 between the first limiting mechanism 8 and the cabinet door 7, preventing separation and improving sealing performance.

[0030] Example 3

[0031] like Figure 1 and Figure 5 As shown, the present invention proposes a sealing structure for a switch cabinet. Compared with Embodiment 1, this embodiment further includes a second sealing mechanism 2. The second sealing mechanism 2 is disposed on the switch cabinet body 1. The second sealing mechanism 2 consists of four sets of limiting seats 6 evenly installed on the switch cabinet body 1, a second sealing gasket 3 abutting between the four sets of limiting seats 6, and a magnet ring 5 embedded in the inner cavity of the second sealing gasket 3. The second sealing gasket 3 abuts against the second sealing part 13 in the first sealing mechanism 11. The limiting seat 6 is L-shaped, and both the second sealing gasket 3 and the second sealing mechanism 2 are U-shaped. The second sealing gasket 3 is made of fluororubber. A second clearance opening 4 is opened on the second sealing gasket 3 and on one side wall near the switch cabinet body 1. The magnet ring 5 passes through the second clearance opening 4 and connects to the inner cavity of the second sealing gasket 3. The magnet ring 5 is attracted to the edge of the open end of the switch cabinet body 1.

[0032] In an optional embodiment, since the second sealing gasket 3 is made of fluororubber, which has a certain degree of flexibility, the second clearance opening 4 is opened, and the magnet ring 5 is inserted into the inner cavity of the second sealing gasket 3 through the second clearance opening 4 to complete the assembly of the second sealing mechanism 2. Then, the four corners of the second sealing mechanism 2 are respectively abutted against the four sets of limit seats 6 until the magnet ring 5 is attracted to the edge of the open end of the switch cabinet body 1, thereby completing the installation of the second sealing mechanism 2. When the cabinet door 7 rotates and closes along the switch cabinet body 1, the second sealing part 13 abuts against the second sealing gasket 3, further improving the sealing performance at the connection between the cabinet door 7 and the open end of the switch cabinet body 1. The second sealing mechanism 2 is easy and quick to disassemble and convenient for regular replacement.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
