Description

Technical Field

[0001] This utility model relates to the field of explosion-proof lighting technology, and in particular to a lighting protection component with explosion-proof function. Background Technology

[0002] With the rapid development of industries such as petroleum, chemical, and mining, lighting fixtures are being used more and more widely in production, warehousing, and rescue operations, and the variety of types is increasing. Preventing accidental explosions of lighting fixtures in hazardous gas environments has become a very important issue.

[0003] Currently, lighting fixtures inevitably generate electrical sparks or form incandescent surfaces during operation. If these sparks come into contact with explosive gas mixtures at production or rescue sites, they can cause explosions, directly endangering the lives of citizens and the safety of state property. Utility Model Content

[0004] In order to solve the problems of the prior art, this utility model provides a lamp protection component with explosion-proof function.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] An explosion-proof lighting fixture protective assembly includes a base, the top of which may even have a transparent protective cover. A docking seat is fixed in the middle of the top of the base. The docking seat is hollow inside. An electrical connector is even located between the inner walls of the docking seat. The top of the electrical connector is fixed to the lighting fixture body. The electrical connector may even have multiple pressure relief components inside. A groove is formed at the bottom of the base. The inner bottom surface of the docking seat communicates with the groove.

[0007] Optionally, the bottom of the base is provided with multiple air passages at equal intervals along the circumferential direction, one end of each air passage penetrates into the interior of the groove, and the other end of each air passage penetrates into the outer surface of the base.

[0008] Optionally, a limiting ring is fixed to the inner wall of the docking seat, and the top of the limiting ring is in contact with the bottom of the electrical connector.

[0009] Optionally, the top of the base is provided with an annular groove, and annular limiting strips are fixed on both inner walls of the annular groove.

[0010] Optionally, a sealing groove is provided on the outer surface of the transparent cover near the bottom edge, the bottom of the transparent cover is engaged inside the annular groove, and the annular limiting strip is engaged inside the sealing groove.

[0011] Optionally, the pressure relief assembly includes a flow channel, which is formed inside the electrical connector. One end of the flow channel extends through to the inner bottom surface of the lamp body, and the other end extends through to the bottom of the electrical connector.

[0012] Optionally, a support ring is fixed between the inner walls of the guide channel, a sealing ring is fixed between the inner walls of the guide channel, a spring is fixed to one side of the support ring, a sealing block is fixed to one end of the spring, and one end of the sealing block is sealed and fitted to one side of the sealing ring.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] 1. In this utility model, both the lamp body and the transparent cover are placed above the base during actual use, and the lamp body is located inside the transparent cover. This allows the lamp body to be isolated from the outside through the transparent cover, preventing it from coming into contact with external explosive substances when the lamp body generates an electric spark or forms a hot layer on its outer surface, thereby preventing an explosion.

[0015] 2. In this utility model, when the electrical light-emitting element inside the lamp body short-circuits or explodes due to an electric spark, a large amount of gas is generated. If the gas cannot be discharged, the gas pressure inside the lamp body will rise instantaneously, leading to the lamp body exploding. The pressure relief component installed inside the electrical connector can protect the lamp body. When the gas pressure inside the lamp body rises, it will push the sealing block towards the spring side, opening the gap between the sealing block and the sealing ring, thereby allowing the gas inside the lamp body to be discharged from the guide channel, preventing an explosion due to excessive gas pressure.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Example 1, such as Figure 1-4 As shown, this utility model provides a technical solution for a lamp protection component with explosion-proof function: it includes a base 1, the top of the base 1 even has a transparent protective cover 4, the top of the base 1 is fixed with a docking seat 3 at the middle, the interior of the docking seat 3 is hollow, the inner wall of the docking seat 3 even has an electrical connector 11, the top of the electrical connector 11 is fixed with a lamp body 10, the interior of the electrical connector 11 even has multiple pressure relief components, the bottom of the base 1 has a groove 7, and the inner bottom surface of the docking seat 3 is connected to the groove 7.

[0026] The effect achieved by the entire embodiment 1 is that, in actual use, both the lamp body 10 and the transparent cover 4 are placed above the base 1, and the lamp body 10 is located inside the transparent cover 4. Thus, the lamp body 10 can be isolated from the outside through the transparent cover 4. When the lamp body 10 generates an electric spark or forms an incandescent layer on the outer surface, it can be prevented from coming into contact with external explosive substances, thereby preventing an explosion.

[0027] Example 2, as Figure 1-4As shown, the bottom of the base 1 has multiple air passages 8 evenly spaced along the circumferential direction. One end of each air passage 8 extends into the interior of the groove 7, and the other end extends into the outer surface of the base 1. A limiting ring 9 is fixed to the inner wall of the docking seat 3. The top of the limiting ring 9 is in contact with the bottom of the electrical connector 11. An annular groove 2 is formed on the top of the base 1. Annular limiting strips 5 are fixed to the inner walls of both sides of the annular groove 2. A sealing groove 6 is formed on the outer surface of the transparent cover 4 near the bottom edge. The bottom of the transparent cover 4 is fitted into the annular groove 2. The position bar 5 is engaged inside the sealing groove 6. The pressure relief assembly includes a guide channel 12, which is opened inside the electrical connector 11. One end of the guide channel 12 extends through to the inner bottom surface of the lamp body 10, and the other end extends through to the bottom of the electrical connector 11. A support ring 13 is fixed between the inner walls of the guide channel 12, and a sealing ring 16 is fixed between the inner walls of the guide channel 12. A spring 14 is fixed to one side of the support ring 13, and a sealing block 15 is fixed to one end of the spring 14. One end of the sealing block 15 is sealed and fitted to one side of the sealing ring 16.

[0028] The effect achieved by the entire embodiment 2 is that when the electrical light-emitting element inside the lamp body 10 short-circuits or explodes due to an electric spark, a large amount of gas is generated. If the gas cannot be discharged, the gas pressure inside the lamp body 10 will rise instantaneously, leading to an explosion of the lamp body 10. The pressure relief component installed inside the electrical connector 11 can protect the lamp body 10. When the gas pressure inside the lamp body 10 rises, it will push the sealing block 15 towards the spring 14, causing the sealing block 15 and the sealing ring 16 to open, thereby allowing the gas inside the lamp body 10 to be discharged from the guide channel 12, preventing an explosion due to excessive gas pressure.

[0029] Working principle: In actual use, both the lamp body 10 and the transparent cover 4 are placed above the base 1, with the lamp body 10 located inside the transparent cover 4. This isolates the lamp body 10 from the outside through the transparent cover 4, preventing it from coming into contact with explosive substances when the lamp body 10 generates an electric spark or forms a hot layer on its outer surface, thus avoiding an explosion. When the electrical light-emitting element inside the lamp body 10 short-circuits or explodes due to an electric spark, a large amount of gas is generated. If the gas cannot be released, the internal pressure of the lamp body 10 will rise instantaneously, leading to an explosion. The pressure relief component inside the electrical connector 11 protects the lamp body 10. When the internal pressure of the lamp body 10 rises, it pushes the sealing block 15 towards the spring 14, opening the gap between the sealing block 15 and the sealing ring 16, thereby allowing the gas inside the lamp body 10 to be discharged from the guide channel 12, preventing an explosion due to excessive pressure.
