[0033] The bottom shell 3 can be used as a base for mounting the lamp panel 5. The groove in the bottom shell 3 can better fix the lamp panel 5. The bottom shell 3 is generally made of metal, which improves the strength. Since the lamp panel 5 is embedded in the bottom shell 3, it can help absorb the heat generated by the lamp panel 5 during operation, thereby improving the heat dissipation capacity of the lamp panel 5. The mounting portion 51 of the lamp panel 5 is locked together with the bottom shell 3, generally by using bolts. After the bolts are locked, they are in the sealed cavity 11, which can protect the bolt structure in the sealed cavity 11 with excellent sealing performance, avoid damage to the bolt due to pollution, and effectively protect the structures of the explosion-proof lamp. The above structure can effectively improve the sealing performance of the explosion-proof lamp, so that the explosion-proof lamp has better explosion-proof performance.

[0034] With reference to Figures 2 to 3 The flexible sealing portion 23 includes a fixed portion 24 and a compression portion 25. One end of the fixed portion 24 is connected to the connecting portion 22, and the other end is connected to the compression portion 25. The fixed portion 24 and the compression portion 25 are integrally formed.

[0035] The sealed cavity 11 has an open end facing the lamp panel 5. The flexible sealing portion 23 is arranged in the open end. One end of the fixed portion 24 away from the connecting portion 22 is bent to form the compression portion 25 facing the open end.

[0036] The flexible sealing portion 23 is protected by the fixed portion 24 and the compression portion 25, which can separate the inside and outside and ensure the sealing performance of the sealing structure 2. The fixed portion 24 is close to the end of the protective shell 1 near the light-transmitting portion 21, which is the first sealing portion. The sealed cavity 11 of the protective shell 1 is provided with an open end, so that the sealing structure 2 can be installed through the open end to play a sealing role. The compression portion 25 is bent by the fixed portion 24. During the process of inserting the sealing structure 2 into the sealed cavity 11, the inner wall of the sealed cavity 11 will apply pressure to the fixed portion 24 and the compression portion 25 respectively. The two pressures interact to clamp the sealing structure 2 while effectively ensuring the sealing performance.

[0037] With reference to Figure 3 The end surface of the fixed portion 24 facing the light-transmitting portion 21 is provided with a threaded locking portion. The sealed cavity 11 is provided with a matching threaded matching portion relative to the threaded locking portion.

[0038] The threaded locking portion and the threaded matching portion are both threaded structures, and the two threaded structures are arranged between the sealed cavity 11 and the fixed portion 24. When the sealing structure 2 is installed, it can gradually enter the sealed cavity 11 by rotating. The compression portion 25 can make the two threaded connections more tightly. The threaded structure can play a guiding role, so that the sealing structure 2 can be firmly fixed in the sealed cavity 11, avoiding the sealing structure 2 from shifting during installation. In addition, the threads can increase the contact area between the sealing structure 2 and the protective shell 1, effectively utilizing the friction force to improve the sealing performance of the explosion-proof lamp.

[0040] In another possible embodiment of the present application, the flexible sealing part 23 is a whole piece of flexible material, when the flexible sealing part 23 is connected to the sealing cavity 11, the flexible sealing part 23 will completely fill the entire sealing cavity 11, which can further improve the anti-vibration capability of the explosion-proof lamp, and the whole piece of flexible sealing part 23 can completely fill the gap of the sealing cavity 11, which can effectively improve the sealing performance, and the whole piece of flexible sealing part 23 can cover the mounting part 51 of the lamp panel 5, which can better protect the locking structure such as bolts between the mounting part 51 and the bottom shell 3, and can better protect the explosion-proof lamp.

[0041] The flexible sealing part 23 can be made of one or more materials such as silicone rubber, fluororubber, and polyurethane. Silicone rubber has good elasticity and high and low temperature resistance, and is commonly used for sealing in food and medical device industries. Fluororubber has very good high temperature resistance and corrosion resistance, and is suitable for sealing in high temperature and harsh environments. Polyurethane has soft hardness and strong wear resistance, and is widely used for sealing in hydraulic and pneumatic equipment. These materials also have good light transmission, and the light-transmitting part 21 can be made of similar materials, so that the sealing structure 2 can be completely integrally formed, ensuring the strength of the entire structure.

[0043] The bottom shell 3 is rotationally connected with a connecting frame, and the connecting frame and the locking members are arranged alternately.

[0044] The bottom of the protective shell 1 is circumferentially cut with a connecting groove 12, and the bottom shell 3 is sleeved on the connecting groove 12, and the two can be rotationally connected. Such a structure can facilitate the alignment of the locking holes between the two by the locking members, and the plurality of locking members are circumferentially uniformly and spacedly arranged, which can effectively ensure the tightness of the connection. Meanwhile, the locking members are arranged on the side of the explosion-proof lamp, which can make the entire lamp body convenient to install and disassemble, and is conducive to reducing the maintenance and installation costs. The connecting frame is arranged between the locking members, which can facilitate the installation, fixation and use of the explosion-proof lamp, and can effectively improve the user experience.

[0046] The receiving portion 31 provided on the bottom shell 3 relative to the lamp panel 5 can be used to store the control chip, and the light emitting components of the lamp panel 5 can be suspended in the explosion-proof lamp, which can further improve the explosion-proof and anti-vibration effect. Even if the lamp panel 5 itself is damaged, the entire shell structure can completely seal the lamp panel 5, avoiding damage to the outside world.

[0047] The outer periphery of the receiving portion 31 is provided with a plurality of heat dissipation fins 32, the heat dissipation fins 32 can play a heat dissipation effect, and the heat dissipation fins 32 can support the bottom shell 3 and the receiving portion 31, effectively improving the structural strength of the bottom shell 3, and the heat dissipation fins 32 wrap the receiving portion 31.
