[0002] Explosion-proof fluorescent lamps are a common type of lighting structure, primarily used in hazardous locations where flammable gases or dust may be present. They prevent potential arcs, sparks, or high heat from igniting the surrounding environment, thus meeting explosion-proof requirements. For example, CN202421743973.X describes an explosion-proof fluorescent lamp whose key technical features include a light source assembly, a lampshade, an adapter, a pin socket, and a sealing gasket. The lampshade is installed on the outside of the light source assembly. The adapter has a connection hole with a first screw connected inside, and a first epoxy resin is injected into the connection hole. A connection cavity is formed in the middle of the adapter. The sealing gasket is located at the end of the connection cavity near the light source assembly, and the pin socket is installed at the end of the connection cavity away from the light source assembly, forming a sealed cavity between the pin socket and the adapter. A second epoxy resin is injected into the connection cavity, and a third epoxy resin is injected into the sealed cavity.

[0003] While it can improve the explosion-proof performance of fluorescent lamps, its overall structure is relatively complex and requires the injection of epoxy resin, which is not conducive to assembly and maintenance operations.

[0033] 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.

[0034] Example 1

[0035] See Figures 1 to 3 As shown, a snap-fit ​​explosion-proof fluorescent lamp structure includes two lamp heads 1 and a lamp tube body 2 snapped between the two lamp heads. In this embodiment, the lamp heads and lamp tube body are conventional structures of the prior art, and are simply applied, so they are not described in detail.

[0036] In this embodiment, two protective end caps 3 are provided. A lamp holder 4 is fixed inside the protective end cap. The lamp holder is fixed inside the protective end cap by screws or buckles. It can be processed and set as needed. At the same time, the lamp head is fixed to the middle of the inner side of the lamp holder away from the protective end cap by a lamp clip 5. The lamp clip is a stainless steel structural component and is fixed to the lamp holder by screws.

[0037] Meanwhile, a square snap-fit ​​cavity 6 is provided on the upper part of the inner side of the lamp holder, and a locking screw 7 is provided on the top surface of the lamp holder; several protrusions 8 are provided on the edge of the protective end cover, and a locking hole 9 is provided on the inner side of the protrusion; the size of the square snap-fit ​​cavity can be processed and set as needed, and the height of the protrusion can be set as needed.

[0038] A connecting tube 10 and a cylindrical light-transmitting cover 11 are arranged between two lamp holders, and a lamp mesh 12 is arranged between two protective end caps; the cylindrical light-transmitting cover is a glass cover or a light-transmitting plastic cover. The lamp mesh is U-shaped, and its ends have protrusions that mate with locking holes; the lamp mesh is directly below the cylindrical light-transmitting cover, and the protrusions are engaged in the locking holes. The lamp mesh includes several parallel support rods and several U-shaped rods, with the U-shaped rods perpendicular to the support rods and welded in place. The shape of the connecting tube matches the shape of the square snap-fit ​​cavity, which can be used to install wires, etc., and the connecting tube can be a plastic structural component. The cylindrical light-transmitting cover can be a glass cover or a light-transmitting plastic cover.

[0039] During assembly, both ends of the connecting tube are inserted into the square snap-fit ​​cavities of the two lamp holders and locked in place by locking screws. Simultaneously, the cylindrical light-transmitting cover is fitted over the outside of the lamp tube body and the connecting tube, with both ends of the cylindrical light-transmitting cover secured to the edges of the lamp holders. The two ends of the lamp mesh are secured into the locking holes of the protective end caps. The cylindrical light-transmitting cover prevents the lamp tube body from directly contacting external objects, improving explosion-proof performance, while the lamp mesh prevents debris from flying during an explosion, enhancing safety. Furthermore, since both the lamp tube body and the connecting tube are housed within the cylindrical light-transmitting cover, the inner diameter of the cover is larger than the outer diameter of the lamp tube body, providing a certain degree of explosion buffering performance.

[0040] In this embodiment, the top surface of the protective end cap is provided with a lifting screw hole; the bottom end of the hollow stud 14 on the lifting bracket 13 is fixed in the lifting screw hole by a sealing ring 15 threaded connection; the power cord of the lamp holder passes through the hollow stud and is connected to an external power source. Furthermore, the lamp holder and the lamp holder's power cord are electrically connected, and the lamp tube body is electrically connected to the lamp holder when inserted. This is a common technical structure. Both the lifting bracket and the hollow stud are conventional structures in the prior art. The connection via the sealing ring improves the sealing at the joint and prevents heat transfer from the wires at the joint.

[0041] In this embodiment, a protective sleeve 16 is provided at the connection between the cylindrical light-transmitting cover and the lamp holder. The protective sleeve can improve the sealing of the connection between the cylindrical light-transmitting cover and the lamp holder, and the protective sleeve is made of rubber, silicone, or plastic, etc.

[0042] In this embodiment, at least two positioning lugs 17 are fixed to the outer edge of the lamp head; the lamp head base is provided with a mounting recess 18, and the lamp clip has a positioning hole 19; during assembly, the positioning lugs are snapped into the positioning holes and their ends extend into the mounting recess. The lamp clip is fixed to the lamp head base with screws, and the lamp head is snapped into the lamp clip, improving the convenience and stability of the connection.

[0043] In this embodiment, a reflector 20 is disposed between the tops of the two protective end caps and fixed with screws, and the cylindrical light-transmitting cover is located directly below the reflector. The reflector can improve the illumination effect and also prevent the splashing of explosion debris.

[0044] In this embodiment, there is one lamp tube body; the number of lamp holders and lamp holders matches the number of lamp tube bodies.

[0045] This utility model has the following positive effects: Its structure is rationally designed, featuring two protective end caps. A lamp holder is fixed inside each end cap, and both ends of the connecting tube are inserted into the square snap-fit ​​cavities of the two lamp holders and locked in place by locking screws. A cylindrical light-transmitting cover is fitted over the outside of the lamp tube body and the connecting tube. Both ends of the light mesh are snapped into the locking holes of the protective end caps for limitation. The connecting tube ensures a relatively stable and reliable position between the two protective end caps and facilitates wiring connections, reducing the impact of the lamp tube body on the wires. Furthermore, the cylindrical light-transmitting cover isolates the heat from the lamp tube body, preventing it from affecting surrounding materials. The light mesh also prevents debris from flying during an explosion, improving explosion-proof effectiveness and safety. Placing the lamp holder inside the protective end caps also protects the connection between the lamp holder and the lamp tube body, enhancing reliability and stability. It also improves the ease of assembly and disassembly, facilitating maintenance and making it highly adaptable.

[0046] Example 2

[0047] See Figure 4 As shown, this embodiment is basically the same as embodiment 1, except that: the lamp tube body is arranged in two side by side. In actual application, the number of lamp tube bodies can also be three or four.

[0048] The number of lamp holders and lamp holder sockets is matched with the number of lamp tube bodies.

[0049] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here.
