Technical Field

[0001] This utility model relates to the field of explosion-proof junction box technology, specifically to an internal partition structure for an explosion-proof junction box. Background Technology

[0002] An explosion-proof junction box is an electrical connection device used in hazardous environments such as those containing explosive gases or dust. Its main function is to safely connect electrical components such as wires and cables together and prevent explosions caused by electrical sparks or high temperatures. It is widely used in industries such as petroleum, chemical, natural gas, coal mining, and pharmaceuticals.

[0003] Currently, there are two types of explosion-proof junction boxes: one is the ordinary explosion-proof junction box, where multiple cables are placed in one chamber during wiring; the other is the partitioned explosion-proof junction box, where cables can be wired into two chambers through internal partitions. However, in the partitioned explosion-proof junction box, the partitions are integrated with the box itself, making it inconvenient to disassemble and adjust. The size of the cable wiring chambers cannot be adjusted according to usage requirements, so improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide an internal partition structure for an explosion-proof junction box, so as to solve the problem that the internal partitions of the partitioned explosion-proof junction box mentioned in the background art cannot be disassembled and adjusted, and their use is limited.

[0006] The fourth partition assembly includes a base box inserted into the explosion-proof wiring outer box. An explosion-proof layer is integrally connected to the inner wall of the base box. Wiring terminals are provided inside the base box. An inner main cover plate is fixedly connected to the top of the base box. An outer cover body covers the top of the explosion-proof wiring outer box body, and the outer cover body is located on top of the inner main cover plate.

[0007] Preferably, the first partition assembly, the second partition assembly, and the third partition assembly all have the same structure as the fourth partition assembly, and the base box is fixedly connected to the explosion-proof wiring outer box by screws.

[0008] Preferably, the outer wall of the explosion-proof wiring box is integrally connected with a connector, and multiple connectors are provided.

[0009] Preferably, the positions of the connecting ports correspond to the positions of the first partition assembly, the second partition assembly, the third partition assembly, and the fourth partition assembly, respectively.

[0010] Preferably, both the outer walls of the base box and the explosion-proof layer are provided with through holes, and the positions of the through holes correspond to the positions of the pipe openings.

[0011] Preferably, the inner main cover plate has multiple openings, and an inner small cover plate is fixedly connected inside each opening.

[0012] Preferably, the inner small cover plate corresponds to the position of the base box, and the inner main cover plate is fixedly connected to the base box by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) While realizing the explosion-proof function of cable wiring, this device can adjust the zoning area according to the needs of the wiring zone to improve the explosion-proof effect of wiring.

[0015] (2) This device uses screws to fix multiple base boxes inside the explosion-proof wiring box. The base boxes can divide the cable into four areas for explosion-proof isolation. At the same time, the base boxes can also be disassembled, so that an appropriate number of base boxes can be disassembled as needed to achieve separation of three areas and two areas, thereby improving the practicality of cable wiring operations and the explosion-proof performance of the cable.

[0016] (3) By setting an inner main cover plate, the device can simultaneously cover and seal the base boxes of the first partition assembly, the second partition assembly, the third partition assembly and the fourth partition assembly. The inner small cover plate on the inner main cover plate can also be opened separately. It can be opened when any of the base boxes of the first partition assembly, the second partition assembly, the third partition assembly and the fourth partition assembly need to be installed or maintained, thereby improving work efficiency.

[0021] 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.

[0022] Please see Figure 1-3This utility model provides a technical solution: an internal partition structure for an explosion-proof junction box, including an explosion-proof outer junction box 1. The outer junction box 1 contains a first partition assembly 3, a second partition assembly 4, a third partition assembly 5, and a fourth partition assembly 6. The first partition assembly 3, second partition assembly 4, and third partition assembly 5 have the same structure as the fourth partition assembly 6. A base box 61 is fixedly connected to the explosion-proof outer junction box 1 by screws. This base box 61 can be disassembled from the explosion-proof outer junction box 1, allowing for operation according to the installation needs of the personnel. Multiple connectors 2 are integrally connected to the outer wall of the explosion-proof outer junction box 1 for connecting external pipes. The positions of the connector ports 2 correspond to the positions of the first partition assembly 3, the second partition assembly 4, the third partition assembly 5, and the fourth partition assembly 6, respectively. This structure facilitates the insertion of cables into the base boxes 61 of the first partition assembly 3, the second partition assembly 4, the third partition assembly 5, and the fourth partition assembly 6. Both the base box 61 and the explosion-proof layer 62 have through holes on their outer walls, the positions of which correspond to the positions of the connector ports 2. The base box 61 can be made of cast steel, and the explosion-proof layer 62 can be made of aluminum alloy. The fourth partition assembly 6 includes a base box 61 inserted inside the explosion-proof wiring outer box 1. The explosion-proof layer 62 is integrally connected to the inner wall of the base box 61. A wiring terminal 63 is provided inside the base box 61. An inner main cover plate 8 is fixedly connected to the top of the 61. The inner main cover plate 8 has multiple openings, and inner small cover plates 9 are fixedly connected inside each opening. The inner small cover plates 9 are hinged to the inner main cover plate 8. During use, the inner small cover plates 9 are threadedly connected to the screw holes pre-drilled at the top of the explosion-proof layer 62, ensuring the protective properties of the explosion-proof layer 62 while also facilitating the stability of the inner small cover plates 9. By opening the inner small cover plates 9, maintenance and other operations can be performed on the interior of the base box 61 of the first partition assembly 3, the second partition assembly 4, the third partition assembly 5, or the fourth partition assembly 6. The inner small cover plates 9 correspond to the positions of the base box 61, and the inner main cover plate 8 is fixedly connected to the base box 61 by screws. The entire assembly can be disassembled from the top of the base box 61 for easy wiring. The top of the explosion-proof wiring outer box 1 is covered by an outer cover 7, which is located on top of the inner main cover plate 8. The wiring terminal 63 of this device is fixed to the bottom of the explosion-proof wiring outer box 1. The top of the wiring terminal 63 passes through the base box 61 and the explosion-proof layer 62 and is located inside the explosion-proof layer 62, which facilitates the subsequent disassembly of the base box 61. The explosion-proof wiring outer box 1 of this device automatically has sufficient explosion-proof performance. Even after the base box 61 is disassembled, the explosion-proof effect of the cables inside the explosion-proof wiring outer box 1 will not be affected. The main purpose of setting up the base box 61 is to separate multiple cables for explosion protection and upgrade the explosion-proof performance. All screws used in this application are high-strength screws.

[0023] Working principle: When using the internal partition structure of this explosion-proof junction box, first open the outer cover 7, then open the inner main cover 8. After opening the inner main cover 8, multiple base boxes 61 inside the explosion-proof junction box 1 are exposed. Next, connect the explosion-proof conduit to the connector 2. Then, pass the cable through the connector 2 into the base boxes 61 of the first partition assembly 3, the second partition assembly 4, the third partition assembly 5, and the fourth partition assembly 6. Next, connect the end of the cable to the terminal block 63 inside the base box 61. During the wiring process, the number of base boxes 61 can be reduced. When disassembling the base box 61, remove the screws that fix the base box 61 to separate the base box 61 from the inside of the explosion-proof junction box 1. After connecting the cable, fix the inner main cover 8 to the base box 61. Finally, fix the outer cover 7 to the explosion-proof junction box 1.
