Description

Technical Field

[0001] The utility model relates to the technical field of boxes, in particular to an explosion-proof box. Background Art

[0002] Explosion-proof cabinets are mainly used in dangerous places where flammable gases and dust exist. They can prevent arcs, sparks and high temperatures that may be generated inside the lamp from igniting flammable gases and dust in the surrounding environment, thereby meeting explosion-proof requirements.

[0017] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0018] The terms "first," "second," and so on, in the specification and claims of this utility model and the accompanying drawings are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product, or end comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed therein, or may optionally include other steps or elements inherent to such process, method, product, or end.

[0019] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] This utility model discloses a specific implementation of an explosion-proof box, please see Figures 1 to 2 , comprising a base 1 and a top cover detachably connected to the base 1.

[0021] Please see Figure 2 The bottom surface of the base 1 is formed with a plurality of reinforcing ribs 31 arranged at intervals along the width direction of the base 1. Each reinforcing rib 31 is provided with a plurality of reinforcing columns 32 arranged at intervals along the length direction of the reinforcing rib 31. The reinforcing ribs 31, the reinforcing columns 32 and the base 1 are an integrally formed structure. The reinforcing ribs 31 can increase the structural strength of the base 1, thereby increasing the overall structural strength of the box. If the box is a metal structure, the reinforcing ribs 31 also contribute to the heat exchange between the box and the outside world, and the reinforcing columns 32 further improve the structural strength of the reinforcing ribs 31. For some longer boxes, the role of the reinforcing columns 32 can prevent the reinforcing ribs 31 from shaking and reduce cracking.

[0022] In order to improve safety and prevent the reinforcing ribs 31 from scratching external objects, the front and rear ends of each reinforcing rib 31 are provided with rounded transition surfaces.

[0023] In this embodiment, combined with Figure 3 The end surface of the base 1 facing the top cover 2 is provided with a plurality of first threaded holes 11 arranged at intervals. The plurality of first threaded holes 11 are arranged along the circumference of the base 1 at the four edges of the base 1. The four edges of the top cover 2 are formed with a plurality of first countersunk holes 21 arranged along the circumference of the top cover 2. The first countersunk holes 21 are aligned with the first threaded holes 11 in the height direction, and the top cover 2 can be fixed to the base 1 by screws. In addition, a notch 211 is provided on the outward side of each first countersunk hole 21. The notch 211 enables construction workers to visually inspect whether the screws are installed in place, which is convenient and safe.

[0024] Please see Figure 3The base 1 has a cavity formed in the middle of the cavity, with a partition 13 formed in the middle to separate the cavity into a first cavity 41 and a second cavity 42. The first cavity 41 and the second cavity 42 are primarily used to house lighting devices or electrical devices. The partition 13 has a plurality of second threaded holes 12 spaced apart along the width of the base 1 on the end surface facing the top cover 2. The top cover 2 has a plurality of second countersunk holes 22 spaced apart along the width of the top cover 2 in the middle. The second countersunk holes 22 are aligned with the second threaded holes 12 in the height direction, allowing the top cover 2 to be fixed to the base 1 using screws. The second countersunk holes 22 can strengthen the connection strength between the top cover 2 and the base 1.

[0025] In this embodiment, a first wiring hole 43 is defined at the bottom of the first cavity 41 , and two second wiring holes 44 are defined at the bottom of the second cavity 42 , thereby facilitating electrical connection between the two cavities.

[0026] Compared with the prior art, the explosion-proof box of this embodiment increases the structural strength of the box shell by adding reinforcing ribs 31 and reinforcing columns 32 on the base 1, solving the problem of low shell structural strength in the past. The overall structure is simple and compact, easy to prepare, and has good safety.

[0027] Finally, it should be noted that the explosion-proof box disclosed in the embodiment of the present invention is only a preferred embodiment of the present invention, which is only used to illustrate the technical solution of the present invention, rather than to limit it.
