Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof distribution boxes, and more specifically to an explosion-proof distribution box with a wire passing structure. Background Art

[0002] Explosion-proof distribution box is a kind of distribution box with explosion-proof performance, mainly including explosion-proof lighting distribution box, explosion-proof power distribution box, explosion-proof and anti-corrosion distribution box, etc. With the rapid development of industries such as petroleum, chemical industry, military industry, engineering, factories, mines, and mining, explosion-proof distribution boxes are more and more widely used in production, storage, and rescue, and there are more and more varieties. How to prevent the accidental explosion of explosion-proof distribution boxes in explosive gas hazardous places has become a very important topic. Since the explosion-proof distribution box inevitably generates electric sparks during operation, once it encounters the explosive gas mixture at the production or rescue site, it will cause an explosion accident.

[0003] After searching, the utility model patent with announcement number CN218513915U discloses a wire hole structure of a distribution box, including a distribution box, wherein a wire hole is provided on the upper surface of the distribution box, a protective coil is inserted in the wire hole, and the protective coil plays a role in protecting the outer skin of the wire and preventing workers from being injured; a large fixed plate is provided on the distribution box, a protective cover is slidably provided between the large fixed plates, a baffle is fixedly provided on the distribution box, the protective cover is pushed to cover the wire hole and fit with the baffle, so as to prevent dust and small organisms from entering the wire hole from above, and to prevent dust and small organisms from entering the wire hole from the side of the protective cover; a small fixed plate is fixedly provided on the upper surface of the distribution box, a push rod is slidably provided between the small fixed plates, a U-shaped push plate is provided at the end of the push rod, and a first rotating shaft is fixedly connected to the other end; a U-shaped baffle is fixedly provided on the upper surface of the distribution box, the U-shaped baffle is located on one side of the wire hole, and the push rod is pushed to drive the U-shaped push plate so that the wire is clamped and fixed on the U-shaped baffle to prevent the wire from falling off.

[0004] However, the above patents have the following shortcomings: multiple lines need to pass through the side of the distribution box, and only one wire hole is not practical; when there are too many lines, they are prone to entanglement, and it is not convenient to reel in and adjust the overly long lines. For this reason, we propose an explosion-proof distribution box with a wire passing structure. Utility Model Content
