Description

Technical Field

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

[0002] The three-chamber, separate-cavity explosion-proof lamp is a type of explosion-proof lamp featuring separate, independent light source chambers for the light source, power supply, and wiring. This design enhances installation convenience and safety. This scientifically designed, three-chamber LED explosion-proof lamp improves explosion-proof performance and service life, while also facilitating routine maintenance and the use of a replaceable light source. In explosion-proof lamps with a replaceable light source, the light source chamber is secured with a removable structure, allowing for easy removal and repair in the event of a problem with the light source.

[0003] The structure and glue filling process of traditional replaceable light sources are as follows:

[0004] In traditional lamps, a circle of single-component sealant is applied on the inner side of the light source cavity cover 6 to bond the glass 12 and the light source cavity cover, forming a sealant groove for easy glue filling. Figure 1-Figure 3 shown.

[0005] However, this method requires two applications of glue. The second application of glue can only be performed after the first application is cured. The purpose of the first application of glue is to stick the glass to the light source cavity cover to form a sealed glue groove to avoid glue leakage when the second application of two-component sealant is applied. If single-component sealant is not applied and two-component sealant is applied directly, glue leakage will occur. The production process is complicated and the glue curing takes a long time, which is not conducive to mass production. Utility Model Content

There is a distance between the inner wall of the lampshade and the light source board, which is set as a light source cavity. The heat dissipation body and the lampshade are connected through the light source cavity body. A glue pouring groove is provided on the light source cavity body, and the lampshade and the light source cavity body are assembled by pouring glue into the glue pouring groove.

[0009] Furthermore, the light source cavity body and the heat dissipation body are connected via threads.

[0010] Furthermore, one end of the lampshade assembled with the light source cavity body extends outward with a convex edge for connecting with the light source cavity cover of the lamp body, and the light source cavity cover is located at the connection between the heat dissipation body and the light source cavity body.

[0025] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0026] The embodiment of the utility model discloses an explosion-proof lamp.

[0027] Reference Figure 4-Figure 7 An explosion-proof lamp includes a lamp body 1, the lamp body 1 includes a heat dissipation body 4, a wiring cavity cover 2, a light source cavity body 6 and a wiring cavity body, the wiring cavity body and the heat dissipation body 6 are threadedly connected, and the heat dissipation body 4 is threadedly connected to the light source cavity body 6. The interior of the heat dissipation body 4 is a power cavity 5, and the cavity formed by the wiring cavity cover 2 and the wiring cavity body is a wiring cavity 3. Figure 4 For example, from top to bottom are the light source cavity 7, the power cavity 5 and the wiring cavity 3. The three cavities are designed independently and can be easily disassembled and replaced.

[0028] The upper end portion of the heat dissipation body 4 is provided with a light source board 8, the overall cross-section of the light source board 8 is trapezoidal, and the upper end portion of the heat dissipation body 4 is provided with a lampshade 12, and there is a distance between the inner wall of the lampshade 12 and the light source board 8, and the distance is set as the light source cavity 7. The heat dissipation body 4 and the lampshade 12 are connected by a light source cavity body 6, the cross-section of the light source cavity body 6 is convex, and a glue filling groove 10 is opened on the light source cavity body 6, as shown in FIG. Figure 7 As shown, a glue potting groove 10 is provided along the circumference of the light source cavity body 6. The lampshade 12 is assembled to the light source cavity body 6 by pouring glue (two-component sealant) into the glue potting groove 10. After pouring resin glue into the glue potting groove 10, the lampshade 12 is installed, meeting explosion-proof requirements. By pre-treating the lampshade with glue in advance, the lampshade 12 can be directly assembled and used during the production process, saving assembly time and improving production efficiency.

[0029] The light source cavity body 6 is connected to the heat sink body 4 via threads. Specifically, the inner wall of the light source cavity body 6 is provided with internal threads, while the outer wall of the heat sink body 4 is provided with external threads. The cooperation of the internal and external threads achieves the purpose of connecting the light source cavity body 6 and the heat sink body 4. The threaded connection between the light source cavity body 6 and the heat sink body 4 makes the light source cavity body 6 an independent structure, improving the convenience of disassembly and replacement, while also meeting explosion-proof requirements.

[0030] A flange 13 extends outward from one end of the lampshade 12 where it is assembled with the light source cavity body 6.

The light source cavity cover 9 is located at the junction of the heat sink body 4 and the light source cavity body 6 and is connected to the heat sink body 4 via bolts. When installing the lampshade 12, the provision of flange 13 not only increases the contact area between the lampshade 12 and the glue potting groove 10, making the assembly of the lampshade 12 more stable and reliable, but also allows the light source cavity cover 9 to fit tightly with the flange 13, further improving the stability and reliability of the lampshade 12 assembly.

[0031] A gasket 11 is provided above the convex edge 13 . The gasket 11 is a silicone pad that can prevent the light source cavity cover 9 from being damaged when pressing the convex edge 13 , thereby protecting the lampshade 12 .

[0032] The lampshade 12 is made of tempered glass.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
