Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and more specifically, to a lighting fixture with an explosion-proof observation window. Background Technology

[0002] In flammable and explosive environments such as petroleum, chemical, and coal mines, explosion-proof lighting fixtures are key equipment to ensure operational lighting and safety.

[0003] Existing explosion-proof lighting fixtures mostly adopt a fully sealed structure to meet explosion-proof requirements. Although this can prevent internal sparks from leaking out and causing danger, it has obvious defects in actual use: On the one hand, when the internal light source, circuit and other components of the lighting fixture need to be inspected regularly, the entire outer shell needs to be disassembled, which is cumbersome and easily damages the sealing performance, increasing the risk of explosion-proof failure; on the other hand, although some lighting fixtures are equipped with observation windows to check the internal working status, most of the existing observation windows are single-layer glass structures, which are not sufficiently explosion-proof.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a lamp with an explosion-proof observation window. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lamp with an explosion-proof observation window.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lamp with an explosion-proof observation window, comprising a lamp housing, wherein a maintenance port is reserved on one side of the lamp housing, and an explosion-proof observation window is detachably connected to the maintenance port;

[0007] The explosion-proof observation window includes double-layer explosion-proof glass, with a vacuum layer formed between the double-layer explosion-proof glass and the edges of the explosion-proof observation window are mounted on the lamp housing by a high-strength metal frame and sealed with the lamp housing by a sealing structure.

[0008] Preferably, the lamp housing is equipped with screws at all four corners of the side of the maintenance port, and the high-strength metal frame is provided with through holes at all four corners of the surface for the screws to pass through. Nuts are threaded onto the outer side wall of the screws.

[0009] Preferably, the sealing structure includes a frame-shaped groove formed on the side of the lamp housing located at the maintenance port and surrounding the maintenance port, and a frame-shaped protrusion integrally formed on the back of the high-strength metal frame and capable of being inserted into the frame-shaped groove, wherein the surface of the frame-shaped protrusion is covered with rubber.

[0010] Preferably, a handle is fixedly connected to the surface of the high-strength metal frame.

[0011] Preferably, a shock-absorbing bracket is installed inside the lamp housing. The shock-absorbing bracket is made of elastic material and supports the light source and circuit components inside the lamp housing.

[0012] Preferably, the front and rear surfaces of the lamp housing are integrally formed with multiple heat dissipation fins arranged in a horizontal array.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model combines explosion-proof and convenient maintenance by setting a maintenance port on one side of the lamp housing and installing a detachable explosion-proof observation window at the maintenance port: the explosion-proof observation window uses double-layer explosion-proof glass and a vacuum layer in the middle, which can effectively enhance the explosion-proof performance and prevent internal sparks from leaking out. Its high-strength metal frame at the edge not only firmly installs the observation window on the lamp housing, but also ensures a tight seal between the observation window and the lamp housing with the sealing structure, meeting the explosion-proof requirements. At the same time, the detachable connection means that when it is necessary to perform regular maintenance on the internal light source, circuit and other components of the lamp, it is not necessary to disassemble the entire housing. Only the explosion-proof observation window needs to be removed, which avoids the problem of damaging the sealing performance and increasing the risk of explosion-proof failure due to the overall disassembly, thus solving the problems in the background technology.

[0015] 2. This utility model provides a convenient force application point for disassembling and installing the explosion-proof observation window by fixing a handle to the surface of the high-strength metal frame;

[0016] 3. This utility model supports the light source and circuit components inside the lamp housing with a shockproof bracket. It can absorb external vibration energy through elastic deformation, buffer the impact, and prevent the light source and circuit components from becoming loose, having poor contact, or being mechanically damaged due to vibration. This not only ensures the stable operation of the internal components and reduces the risk of sparks caused by component failure, but also extends the service life of the lamp. It is especially suitable for use in industrial environments with vibration. Attached Figure Description

[0025] like Figure 1-5 As shown, this utility model provides a lamp with an explosion-proof observation window, including a lamp housing 1, a maintenance port 2 reserved on one side of the lamp housing 1, and an explosion-proof observation window 3 detachably connected to the maintenance port 2;

[0026] The explosion-proof observation window 3 includes double-layer explosion-proof glass, with a vacuum layer formed between the double-layer explosion-proof glass and the edges of the explosion-proof observation window 3 are mounted on the lamp housing 1 by a high-strength metal frame 4 and sealed with the lamp housing 1 by a sealing structure.

[0027] This utility model combines explosion-proof protection with convenient maintenance by setting a maintenance port 2 on one side of the lamp housing 1 and installing a detachable explosion-proof observation window 3 at the maintenance port 2. The explosion-proof observation window 3 uses double-layer explosion-proof glass and an intermediate vacuum layer, which can effectively enhance the explosion-proof performance. (The double-layer explosion-proof glass itself has high impact resistance and shatter resistance, and can directly resist the impact of sparks and high-temperature fragments that may be generated inside, avoiding the single layer of glass from breaking due to excessive force. The intermediate vacuum layer, because it has no air medium, can block the flame from spreading outward through convection and reduce heat conduction, avoiding danger caused by high temperature in the external environment. At the same time, the vacuum layer can also buffer the impact of internal pressure fluctuations on the glass, forming a "physical barrier + medium isolation".) The dual protection significantly improves the explosion-proof effect, preventing internal sparks from leaking out. The high-strength metal frame 4 on its edge not only securely installs the observation window on the lamp housing 1, but also, together with the sealing structure, ensures a tight seal between the observation window and the lamp housing 1, meeting the explosion-proof requirements. At the same time, the detachable connection means that when it is necessary to perform regular maintenance on the internal light source, circuit and other components of the lamp, it is not necessary to completely disassemble the housing. Only the explosion-proof observation window 3 needs to be removed, avoiding the problem of damaging the sealing performance and increasing the risk of explosion-proof failure due to complete disassembly.

[0028] The following is the specific structure of the detachable and sealed connection between the explosion-proof observation window 3 and the lamp housing 1: Screws 5 are installed at the four corners of the lamp housing 1 located on the side of the maintenance port 2. Through holes 401 for the screws 5 to pass through are opened at the four corners of the surface of the high-strength metal frame 4. Nuts 6 are threaded onto the outer side wall of the screws 5. The sealing structure includes a frame-shaped groove 101 opened on the side of the lamp housing 1 located on the maintenance port 2 and surrounding the maintenance port 2, and a frame-shaped protrusion 402 integrally formed on the back of the high-strength metal frame and able to be inserted into the frame-shaped groove 101. The surface of the frame-shaped protrusion 402 is covered with rubber.

[0029] In the connection with the lamp housing 1, the screws 5 at the four corners of the maintenance port 2 of the lamp housing 1 pass through the through holes 401 at the four corners of the high-strength metal frame 4 and are then tightened by the nuts 6, forming a stable and detachable connection structure. This design allows the explosion-proof observation window 3 to be removed simply by unscrewing the nuts 6 during maintenance, without the need to disassemble the entire housing, thus avoiding damage to the sealing performance caused by overall disassembly and reducing the risk of explosion-proof failure. In terms of sealing, the frame-shaped groove 101 of the lamp housing 1 surrounding the maintenance port 2 forms a precise fit with the frame-shaped protrusion 402 integrally formed on the back of the high-strength metal frame 4. The rubber layer covering the surface of the frame-shaped protrusion 402, under the tightening force of the screws 5 and nuts 6, allows the frame-shaped protrusion 402 to be tightly embedded in the frame-shaped groove 101. The rubber is squeezed and fills the gap, forming a double seal (structural fit seal + rubber elastic seal), ensuring the sealing performance between the explosion-proof observation window 3 and the lamp housing 1, and meeting the explosion-proof sealing requirements.

[0030] Furthermore, firstly, the high-strength metal frame 4 is fixedly connected to a handle 7, providing a convenient point of force for disassembling and installing the explosion-proof observation window 3. Secondly, both the front and rear sides of the lamp housing 1 are integrally formed with multiple heat dissipation fins 102 arranged in a horizontal array, which can significantly improve heat dissipation efficiency by increasing the contact area with air, helping internal light sources, circuits and other components to quickly dissipate heat, avoiding performance impact or safety hazards caused by overheating. Finally, the lamp housing 1 is equipped with a shock-absorbing bracket 8, which is made of elastic material. The shock-absorbing bracket 8 supports the light source and circuit components inside the lamp housing 1, and can absorb external vibration energy through elastic deformation, buffering impact and preventing the light source and circuit components from loosening, poor contact or mechanical damage due to vibration. This not only ensures the stable operation of internal components and reduces the risk of sparks caused by component failure, but also extends the service life of the lamp, making it especially suitable for use in industrial environments with vibration.
