Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to an explosion-proof lighting distribution box. Background Technology

[0002] Explosion-proof lighting distribution boxes are special electrical devices designed for use in hazardous environments such as petroleum, chemical, mining, and gas industries. Their core design concept lies in effectively isolating the electrical components (such as circuit breakers, contactors, and relays) within a robust, explosion-proof enclosure from external flammable and explosive gases and dust. This prevents the propagation of internal explosion energy, fundamentally avoiding large-scale explosions in the surrounding environment and ensuring the safety of life and property.

[0003] In existing technologies, the doors and bodies of such explosion-proof distribution boxes are typically fastened together using multiple high-strength screws. This connection method ensures sufficient mechanical strength and sealing between the door and the body, meeting the stringent requirements of the explosion-proof joint surface, thereby maintaining the explosion-proof integrity of the box.

[0004] However, in practical applications, this design has a significant drawback: the screws used for fixing are usually completely exposed. Because explosion-proof lighting distribution boxes are deployed in harsh industrial environments, they not only face the dangers of flammability and explosion but are also frequently exposed to complex conditions such as humidity, salt spray, corrosive chemical gases, or dust. Under long-term exposure, the exposed screw threads and heads are highly susceptible to rust and corrosion, and may even become clogged with oil, dust, and other foreign matter.

[0005] This problem can lead to a series of serious consequences: First, when the equipment needs regular maintenance or emergency power outages, maintenance personnel will find it difficult or even impossible to unscrew the rusted screws, greatly increasing maintenance difficulty and time costs, and affecting work efficiency; Second, during forced disassembly, the screws are prone to stripping or breaking, making it impossible to open or close the cabinet door properly, seriously damaging the integrity of the equipment's explosion-proof structure and creating a huge safety hazard; Finally, the rusted screws also affect the overall aesthetics and reliability of the equipment.

[0006] Therefore, there is an urgent need for a protection solution for the screws on the doors of explosion-proof lighting distribution boxes to address their vulnerability to corrosion and difficulty in disassembly, thereby improving the maintainability, reliability, and service life of the equipment while ensuring explosion-proof performance. Utility Model Content

[0007] The present invention provides an explosion-proof lighting distribution box to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] An explosion-proof lighting distribution box includes a box body and a door that can be rotated and opened on the front side of the box body. Several screw grooves extend outward from the edge of the front wall of the door, and screws for fixing the door to the box body are screwed into each of the screw grooves. Connecting seats extend outward from both side walls of the box body, and connecting blocks are detachably connected to each connecting seat. Several anti-loss ropes are connected to one end of each connecting block, and a protective plug is connected to the end of each anti-loss rope. Each protective plug is inserted into a corresponding screw groove to protect the screws.

[0010] Preferably, a first magnet is embedded in the connecting seat, and a second magnet that attracts the first magnet is embedded in the end face of the connecting block that is in contact with the connecting seat.

[0011] Preferably, the protective plug is made of elastic rubber material and is used to tightly fit into the screw groove.

[0012] Beneficial effects

[0013] The explosion-proof lighting distribution box provided in this embodiment of the utility model has at least one of the following technical effects:

[0014] 1. By setting a protective plug, it can be tightly inserted into the screw groove, effectively isolating the screw from external moisture and corrosive media, fundamentally preventing screw corrosion, ensuring that it remains detachable for a long time, and greatly reducing maintenance difficulty and cost.

[0015] 2. The protective plug is connected to the connecting block on the side of the box via an anti-loss rope, which prevents the protective plug from falling off or being lost during maintenance, ensuring the integrity of the parts and improving the convenience of operation and the reliability of the equipment.

[0016] 3. The connecting block and the connecting seat are connected by magnetic attraction, which is convenient for disassembly and assembly and has a stable structure. It not only facilitates the unified management of the protective plug, but also does not affect the appearance of the box and the explosion-proof performance. It has strong overall practicality and significantly improves the adaptability and service life of the explosion-proof distribution box in harsh environments. Attached Figure Description

[0026] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0027] like Figure 1-4 The diagram shown is a structural schematic of an explosion-proof lighting distribution box according to a preferred embodiment of the present invention.

[0028] This embodiment provides an explosion-proof lighting distribution box, including a box body 1 and a door 2 that is rotatably mounted on the front side of the box body 1 via a hinge. Several protruding screw grooves 3 are formed outwardly extending from the front edge of the door 2, and screws 4 for fastening the door 2 to the box body 1 are screwed into each screw groove 3.

[0029] The left and right side walls of the housing 1 are each fixedly provided with outwardly extending connecting seats 5. Connecting blocks 6 are detachably connected to the connecting seats 5 by magnetic adsorption. Specifically, a first magnet 9 is embedded inside the connecting seat 5, and correspondingly, a second magnet 10 that attracts the first magnet 9 is embedded on the end face of the connecting block 6 that is in contact with the connecting seat 5, thereby achieving stable docking and convenient separation of the two.

[0030] Several anti-loss ropes 7 are attached to the connecting block 6, and a protective plug 8 is fixedly connected to the end of each anti-loss rope 7. In this embodiment, the protective plug 8 is integrally molded from elastic rubber material, and its shape is designed as a frustum or cylinder that matches the screw groove 3. It can be tightly inserted into the corresponding screw groove 3, completely wrapping and isolating the screw head 4 inside, and playing a protective role against dust, moisture and corrosion.

[0031] When the cabinet door 2 needs to be opened for maintenance, the operator can remove each protective plug 8 in turn. Due to the pull of the anti-loss rope 7, the protective plug 8 is still connected to the connecting block 6, which effectively prevents the loss of parts. After the operation is completed, simply put each protective plug 8 back into the corresponding screw slot 3 and fix the connecting block 6 to the connecting seat 5 by magnetic attraction. The whole is convenient to use and highly reliable, and is especially suitable for the maintenance of explosion-proof equipment in harsh environments.

[0032] The explosion-proof lighting distribution box of this utility model can be installed, connected or set up in a common mechanical way, and can be implemented as long as it can achieve its beneficial effect.

[0033] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
