Description

Technical Field

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

[0002] Lighting devices are combinations of equipment that can convert electrical energy into light energy to provide illumination. Explosion-proof lighting devices are generally used in industrial lighting.

[0003] In traditional lighting devices, the protective frame is usually directly connected to the light body with bolts, which is very troublesome during installation and disassembly. In addition, such devices have poor heat dissipation performance. Therefore, we propose an explosion-proof lighting device. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof lighting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof lighting device, including a mounting plate, a lighting lamp body fixedly mounted on the bottom end of the mounting plate, a threaded groove opened on the bottom edge of the mounting plate, a threaded ring threadedly connected to the inner wall of the threaded groove, a plurality of notches opened on the upper end of the side wall of the threaded ring, a heat insulation ring fixedly connected to the bottom end of the threaded ring, a protective frame fixedly connected to the bottom end of the heat insulation ring, a plurality of heat-conducting plates embedded in the outer wall of the lighting lamp body, and a plurality of heat sinks embedded in the lower end of the outer wall of the plurality of heat-conducting plates.

[0006] Preferably, each of the protective frames is fixedly connected with a number of reinforcing ribs.

[0007] Preferably, all of the heat sinks are arranged in an arc shape.

[0008] Preferably, one end of each of the heat-conducting plates is in contact with the inner wall of the threaded ring.

[0009] Preferably, all of the heat sinks are located inside the protective frame.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by using the threaded ring, threaded groove, mounting plate, and protective frame together, the lighting body and mounting plate can be easily disassembled and assembled. Furthermore, the heat-conducting plate and several heat sinks can dissipate heat from the inside of the lighting body. Some of the heat will be transferred to the threaded ring through the heat-conducting plate. By causing the threaded ring to expand due to heat, the stability between it and the threaded groove can be increased, thus preventing the connection from becoming loose. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: an explosion-proof lighting device, including a mounting plate 1, a lighting body 2 fixedly mounted on the bottom end of the mounting plate 1, a threaded groove 101 opened on the bottom edge of the mounting plate 1, a threaded ring 11 threadedly connected to the inner wall of the threaded groove 101, a plurality of notches 102 opened on the upper end of the side wall of the threaded ring 11, a heat insulation ring 12 fixedly connected to the bottom end of the threaded ring 11, a protective frame 13 fixedly connected to the bottom end of the heat insulation ring 12, a plurality of heat-conducting plates 21 embedded in the outer wall of the lighting body 2, and a plurality of heat sinks 22 embedded in the lower end of the outer wall of the plurality of heat-conducting plates 21.

[0018] Furthermore, each of the protective frames 13 is fixedly connected with several reinforcing ribs 14, which can increase the stability of the protective frame 13.

[0019] Furthermore, several heat sinks 22 are arranged in an arc shape, which can increase the heat dissipation effect.

[0020] Furthermore, one end of each of the several heat-conducting plates 21 is in contact with the inner wall of the threaded ring 11, and the heat from the heat-conducting plates 21 is transferred to the inside of the threaded ring 11 through the heat-conducting plates 21.

[0021] Furthermore, several heat sinks 22 are located inside the protective frame 13 to prevent the heat sinks 22 from being easily damaged when they are on the outside.

[0022] Specifically, when using this utility model, firstly, the rotating protective frame 13 drives the threaded ring 11 through the heat insulation ring 12. The threaded ring 11 will rotate and be inserted into the threaded groove 101. This installation and disassembly method is very convenient and avoids wasting time on bolt connections. When the lighting body 2 is turned on for a period of time, it will emit heat. The heat will be transferred to several heat sinks 22 and the threaded ring 11 through the heat conduction plate 21. The heat sinks 22 can dissipate heat from the lighting body 2. When some of the heat is transferred to the threaded ring 11, the threaded ring 11 will expand due to heat and squeeze the threaded groove 101 to prevent the connection from becoming loose.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
