[0016] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0017] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0018] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In industries such as petroleum, chemical, coal mining, pharmaceuticals, and grain and oil processing, flammable and explosive gases, vapors, or dust are often present in the production environment. In such hazardous locations, ordinary lighting fixtures may generate electric sparks, arcs, or excessively high surface temperatures during normal operation, thus becoming ignition sources and causing serious explosions, posing a significant threat to life and property. Therefore, these locations must use specialized explosion-proof lighting fixtures. LED explosion-proof lights use LEDs (light-emitting diodes) as the light source, and the lamp housing and circuitry are specially designed for explosion protection, making them safe for use in flammable and explosive hazardous locations.

[0020] Existing LED explosion-proof lights typically have housings that are either one-piece or split. One-piece housings are not convenient for installing internal components, while split housings usually use screws to connect the two housings. This connection method is prone to failure due to screw rust, which can cause the two housings to loosen and reduce the explosion-proof performance of the LED explosion-proof light.

[0021] Based on this, this application provides an LED explosion-proof light.

[0022] Example 1 like Figures 1-2 As shown in the figure, this embodiment provides an LED explosion-proof lamp housing, the housing including a bottom shell 1 and a top shell 2, the bottom shell 1 and the top shell 2 being detachably connected, and a mounting cavity for mounting components being formed between the bottom shell 1 and the top shell 2; The bottom shell 1 is provided with mounting holes, and the top shell 2 is provided with a connector 21 that connects to the mounting holes; the bottom shell 1 and the top shell 2 are also provided with a snap-fit ​​assembly 5; the snap-fit ​​assembly 5 includes a snap-fit ​​slot 52 provided on the bottom shell 1 and a connecting hook 51 provided on the top shell 2, and the connecting hook 51 is adapted to the snap-fit ​​slot 52.

[0023] The aforementioned LED explosion-proof lamp, as described in this utility model, belongs to the field of explosion-proof lighting technology. The LED explosion-proof lamp includes a housing, comprising a bottom shell 1 and a top shell 2, which are detachably connected, forming a mounting cavity for mounting components. The bottom shell 1 has mounting holes, and the top shell 2 has connectors 21 that connect to these mounting holes. The bottom shell 1 and top shell 2 also have a snap-fit ​​assembly 5. The snap-fit ​​assembly 5 includes a bayonet 52 on the bottom shell 1 and a connecting hook 51 on the top shell 2, the hook 51 being adapted to the bayonet 52. This explosion-proof lamp is easy to assemble, and the two separate housings are fixed together by the snap-fit ​​assembly 5, ensuring long-term connection stability and contributing to the overall explosion-proof capability of the lamp body.

[0024] During assembly, first install the LED light source, drive circuit and other components into the mounting cavity of the bottom shell 1; then align the connecting hook 51 of the front shell 2 with the snap 52 of the bottom shell 1, insert it along the snap 52 and make the connecting hook 51 engage with the connecting rod (at this time, the front shell 2 and the bottom shell 1 are initially positioned, and the protrusion of the connecting step fits against the front shell 2 to form a preliminary seal); finally, the connecting piece 21 (bolt) on the front shell 2 is fastened to the mounting hole (threaded hole) of the bottom shell 1 to complete the shell closure.

[0025] During disassembly and maintenance, first loosen the connector 21, then pull the connector 51 out of the latch 52 to separate the bottom shell 1 and the front shell 2. The operation is convenient.

[0026] This explosion-proof light employs a dual-fixing structure of "clamping component 5 + bolt connection." The clamping component 5 enables rapid positioning, while the bolt connection ensures long-term stability without loosening. This solves the problems of "cumbersome disassembly and assembly" or "easy loosening" associated with single-connection methods, significantly improving maintenance efficiency. Furthermore, all components (clamping slot 52, connecting hook 51, connecting step, etc.) are mechanical structures, requiring no complex machining processes, making them suitable for mass production and reducing manufacturing costs.

[0027] Furthermore, the bayonet 52 includes two mounting plates disposed on the bottom shell 1, the two mounting plates being arranged in parallel; a connecting rod is disposed between the two mounting plates, and the bayonet 52 is formed between the connecting rod and the mounting plates.

[0028] Furthermore, the snap-fit ​​components 5 are symmetrically arranged on the opposite edges of the bottom shell 1 and the top shell 2, and 1-2 snap-fit ​​components 5 are provided on each edge.

[0029] Furthermore, the faceplate 2 is provided with a light-transmitting cover 3 made of a high-transmittance, high-impact-resistance material. The light-transmitting cover 3, made of a high-transmittance, high-impact-resistance material, together with the outer protective net 4, can resist external collisions and dust impacts (such as crushed stones in coal mines and impacts from hard objects in chemical workshops), extending the service life of the lamp.

[0030] Furthermore, a protective net 4 is also provided on one side of the faceplate 2.

[0031] Furthermore, a connecting step is provided at the connection between the bottom shell 1 and the front shell 2, and a protruding strip is provided at the connecting step. The connecting step of the bottom shell 1 and the front shell 2, together with the protruding strip, increases the sealing contact area at the connection, effectively preventing flammable and explosive gases from entering the installation cavity; at the same time, the double connection structure avoids gaps caused by loose shells, meeting the sealing requirements of explosion-proof equipment.

[0032] Furthermore, the bottom shell 1 is provided with a plurality of mounting feet 11, and each mounting foot 11 is provided with a mounting hole.

[0033] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings. In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0034] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0035] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
