[0002] An explosion-proof lamp is a type of lighting fixture with explosion-proof performance, which refers to a lighting fixture used in dangerous places where flammable gases and dust exist. It can prevent electric arcs, sparks, and high temperatures that may be generated inside the lamp from igniting the flammable gases and dust in the surrounding environment, thereby meeting the explosion-proof requirements.

[0003] For example, an explosion-proof signal lamp proposed in the existing explosion-proof lamp with the patent application number "CN202221392715.2" has structures such as a signal lamp base, a lampshade, and an adapter seat. An external thread of the adapter seat is provided on the outer periphery of the adapter seat, and the upper section of the inner hole is in threaded cooperation with the outer periphery thread below the lampshade. The lampshade of the explosion-proof lamp is threadedly connected to the adapter seat of the lamp base, and the connection between the two is firm.

[0004] However, in the prior art, the lampshade and the lamp base are installed and fastened by threads. It is necessary to hold the side wall of the lampshade and use a relatively large force to turn it. It is inconvenient to turn and not easy to disassemble and repair. Therefore, an explosion-proof lamp installation structure is proposed. Content of the Utility Model

Detailed Embodiments

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] An explosion-proof lamp installation structure, as Figures 1 - 5 shown, includes a lamp holder 2. One end of the lamp holder 2 is fixedly connected with an installation seat 1, and the installation seat 1 is used for wire threading and installation of the explosion-proof lamp. The other end of the lamp holder 2 is threadedly connected with a transparent lamp cover 16. A lamp cavity 17 is opened inside the lamp holder 2, and parts such as a light bulb are installed inside the lamp cavity 17. A fixing ring 5 is fixedly connected to the inner wall of the lamp cavity 17. Multiple fixing blocks 6 are fixedly connected to the upper end of the fixing ring 5, and the multiple fixing blocks 6 are arranged in a circumferential array. Two pressing rods 12 are slidably connected to the transparent lamp cover 16, and both of the two pressing rods 12 are perpendicular to the fixing ring 5. A pressing ring 8 is fixedly connected to the ends of the two pressing rods 12 located inside the transparent lamp cover 16. Multiple pressing blocks 9 are fixedly connected to the surface of the pressing ring 8 close to the fixing ring 5, and the multiple pressing blocks 9 are arranged in a circumferential array. The multiple pressing blocks 9 are respectively in extrusion cooperation with the multiple fixing blocks 6.

[0025] When disassembling the transparent lamp cover 16, first fix the transparent lamp cover 16 and do not fix the lamp holder 2. Press the two pressing rods 12, and the pressing rods 12 drive the pressing ring 8 to descend. The multiple pressing blocks 9 respectively extrude the multiple fixing blocks 6, giving the multiple fixing blocks 6 a force to move in one direction, driving the multiple fixing blocks 6 to drive the lamp holder 2 to rotate to a certain extent, so that the transparent lamp cover 16 and the lamp holder 2 are twisted. By converting the pressing force into a twisting force, there is no need to hold the side wall of the transparent lamp cover 16 and twist it, reducing the twisting difficulty between the lamp holder 2 and the transparent lamp cover 16 and facilitating disassembly and maintenance.

[0026] As Figures 3 - 5 shown, the multiple fixing blocks 6 and the pressing blocks 9 are both set as right-angled trapezoids, and the inclined surfaces of the pressing blocks 9 are in extrusion cooperation with the inclined surfaces of the fixing blocks 6. Multiple springs 10 are fixedly connected between the pressing ring 8 and the transparent lamp cover 16, and the multiple springs 10 are arranged in a circumferential array.

[0027] When the inclined surfaces of the multiple pressing blocks 9 extrude the inclined surfaces of the fixing blocks 6, the springs 10 are stretched. Since the pressing ring 8 cannot rotate, the pressing blocks 9 cannot shift, and only the fixing blocks 6 can shift. The shifting direction of the fixing blocks 6 is the same as the loosening direction of the lamp holder 2. The shifting of the fixing blocks 6 drives the lamp holder 2 to rotate. When the pressing rods 12 are not pressed, the springs 10 recover their deformation, pulling the pressing plate to lift, and the pressing blocks 9 and the fixing blocks 6 are separated. The already loosened lamp holder 2 can be easily twisted, preventing the pressing blocks 9 from affecting the large-scale twisting of the lamp holder 2.

[0028] As Figures 3 - 5As shown, a threaded ring 4 is fixedly connected to one end of the lamp holder 2 away from the mounting base 1. An external thread is provided on the outer wall of the threaded ring 4, and a mounting ring 7 is fixedly connected to the transparent lamp cover 16. An internal thread is provided on the inner wall of the mounting ring 7. The outer wall of the threaded ring 4 is threadedly connected to the inner wall of the mounting ring 7.

[0029] The threaded ring 4 of the lamp holder 2 is threadedly connected to the mounting ring 7 of the transparent lamp cover 16, and the inside of the lamp cavity 17 is sealed and explosion-proof.

[0030] As Figure 3 shown, round blocks 15 are fixedly connected to the upper ends of the two groups of pressure rods 12. An elastic sealing ring 14 is clamped between the side walls of the two groups of pressure rods 12 and the transparent lamp cover 16. The elastic sealing ring 14 is used to seal between the side wall of the pressure rod 12 and the transparent lamp cover 16.

[0031] The round block 15 increases the pressing surface of the pressure rod 12, facilitating the pressing of the pressure rod 12. The elastic sealing ring 14 seals the connection between the pressure rod 12 and the transparent lamp cover 16, and the sealing ring does not affect the pressing of the pressure rod 12.

[0032] As Figure 3 shown, a sealing gasket 11 is clamped on the inner wall of the mounting ring 7, and the end of the threaded ring 4 is in extrusion fit with the sealing gasket 11.

[0033] The sealing gasket 11 increases the installation sealing performance between the transparent lamp cover 16 and the lamp holder 2.

[0034] As Figure 1 shown, a plurality of heat dissipation fins 3 are fixedly connected to the side wall of the lamp holder 2. The plurality of heat dissipation fins 3 are arranged in a circumferential array. A plurality of anti-slip blocks 13 are fixedly connected to the outer wall of the mounting ring 7. The plurality of anti-slip blocks 13 are arranged in a circumferential array.

[0035] The heat dissipation fins 3 enhance the heat dissipation effect of the explosion-proof lamp. The anti-slip blocks 13 facilitate the fixing of the transparent lamp cover 16 and increase the friction between the transparent lamp cover 16 and the hand.

[0036] The working principle of an explosion-proof lamp installation structure provided by the present utility model is as follows:

[0037] When disassembling the transparent lamp cover 16, first fix the transparent lamp cover 16 and do not fix the lamp holder 2. Press the two groups of pressure rods 12. The pressure rods 12 drive the pressure ring 8 to descend, and the spring 10 is compressed. The plurality of pressure blocks 9 respectively press the plurality of fixing blocks 6, applying a force to the plurality of fixing blocks 6 to move in one direction, driving the plurality of fixing blocks 6 to drive the lamp holder 2 to rotate to a certain extent, so that the transparent lamp cover 16 and the lamp holder 2 are loosened. By converting the pressing force into a screwing force, there is no need to hold the side wall of the transparent lamp cover 16 and turn it, reducing the difficulty of screwing between the lamp holder 2 and the transparent lamp cover 16 and facilitating disassembly and maintenance.

[0038] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
