[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] The following gives specific embodiments.

[0033] It is divided into two embodiments according to different usage scenarios;

[0034] Embodiment 1:

[0035] Please refer to Figures 1-6, an explosion-proof LED tube lamp of the present utility model includes a light-transmitting lamp cover 1, a front lamp assembly 2 and a rear lamp assembly 3 respectively arranged at both ends of the light-transmitting lamp cover 1. A circuit board 4 is arranged inside the light-transmitting lamp cover 1 on the rear lamp assembly 3. An array of LED light-emitting components 5 is assembled on the circuit board 4. The LED light-emitting components 5 are used to provide a floodlight source. A reflector 51 is arranged around the LED light-emitting components 5 on the circuit board 4. A reflector cup 6 is arranged inside the front lamp assembly 2. An LED lamp bead 7 is arranged inside the reflector cup 6. The LED lamp bead 7 is used to provide a spotlight source. A battery 41 is arranged on one side of the circuit board 4. The battery 41 is used to supply power to the LED light-emitting components 5 and the LED lamp bead 7. A transparent isolation cover is arranged on the reflector cup 6 for isolating the LED lamp bead 7 from the inside of the reflector cup 6 and ensuring light transmittance. A sleeve 10 is arranged on the rear lamp assembly 3. A telescopic mechanism 11 is assembled inside the sleeve 10. The telescopic mechanism 11 is used to extend the length of the explosion-proof LED tube lamp;

[0036] The telescopic mechanism 11 includes a first telescopic tube 111 slidably arranged inside the inner diameter of the sleeve 10, a second telescopic tube 112 slidably arranged inside the inner diameter of the first telescopic tube 111, and a third telescopic tube 113 slidably arranged inside the inner diameter of the second telescopic tube 112. A limiting mechanism 12 is arranged between the telescopic mechanism 11 and the sleeve 10 to prevent the telescopic mechanism 11 from falling off; the limiting mechanism 12 includes a movable groove 121 and a limiting block 122 correspondingly arranged for the movable groove 121. A limiting mechanism 12 is also arranged among the first telescopic tube 111, the second telescopic tube 112 and the third telescopic tube 113 to prevent the three from falling off;

[0037] Fixing mechanisms 13 are provided at both the beginning and the end of the telescopic stroke of the sleeve 10 and the first telescopic tube 111 for fixing the positions of the sleeve 10 and the first telescopic tube 111. Fixing mechanisms 13 are also provided at the beginning and the end of the telescopic strokes among the first telescopic tube 111, the second telescopic tube 112, and the third telescopic tube 113 for restricting their positions. The fixing mechanism 13 includes a plug 131 and a slot 132 corresponding to the plug 131. Both the plug 131 and the slot 132 are isosceles trapezoid structures, and the depth of the slot 132 is greater than the length of the plug 131. During operation, when workers are operating in a narrow or restricted space and need to adjust the length of the explosion-proof LED bar tube light, the workers first rotate the first telescopic tube 111, the second telescopic tube 112, and the third telescopic tube 113 to move the plugs 131 provided on them out of the corresponding slots 132 to complete the unlocking of the three tubes. Then, the first telescopic tube 111, the second telescopic tube 112, and the third telescopic tube 113 are pulled out until the end of the extended formation. Then, the first telescopic tube 111, the second telescopic tube 112, and the third telescopic tube 113 are rotated again to insert the plugs 131 on them into the slots 132 at the corresponding positions to fix the positions of the first telescopic tube 111, the second telescopic tube 112, and the third telescopic tube 113. At the same time, when the three tubes move, they will respectively drive the limit blocks 122 above them to move in the movable slots 121, and the movable slots 121 limit the telescopic strokes of the three tubes. Thus, the extended length of the explosion-proof LED bar tube light can be adjusted to be longer. On the contrary, when it is necessary to retract the telescopic mechanism 11, the opposite operation to the above method can be performed. It is convenient for carrying and storage, reducing space occupation. When the telescopic function is not used, the explosion-proof LED bar tube light can be retracted to a shorter length, which is convenient for carrying and storage, reducing space occupation, and facilitating handling and storage in a narrow space or during transportation. Through the cooperation between the above structures, the operation flexibility is enhanced, enabling the explosion-proof LED bar tube light to adjust its length according to the specific requirements of the operation site. Whether it is working at height or reaching into a narrow space, it can easily cope, greatly improving the operation flexibility and convenience, being able to adapt to more diverse working environments and lighting requirements, thereby broadening its application scenarios and having a wider scope of application, and being more practical than the existing explosion-proof LED bar tube lights.

[0038] Further, a charging port 14 is provided on the rear lamp assembly 3, and a rubber plug 15 is provided on one side of the charging port 14. During operation, when the battery 41 runs out of power, the charger can be inserted into the charging port 14 to charge the battery 41. When not in the charging state, the rubber plug 15 is inserted into the charging port 14 to isolate it, preventing water, dust, and impurities from entering and affecting the normal use of the device.

[0039] Further, a first switch 8 for turning on and off the LED light-emitting component 5 and a second switch 9 for turning on and off the LED lamp beads 7 are provided on the rear lamp assembly 3. During operation, in different working environments, the staff may need the explosion-proof LED tube light to provide a floodlight or a spotlight. Press the first switch 8 to turn on and off the LED light-emitting component 5 to provide a floodlight. When the second switch 9 is pressed, the LED lamp beads 7 are turned on and off to provide a spotlight, which can meet different operation requirements.

[0040] Further, the transparent lamp cover 1 is rotationally assembled with the front lamp assembly 2 and the rear lamp assembly 3. One side of the transparent lamp cover 1 is fixedly connected to one side of the sleeve 10. First lenses 01, second lenses 02, third lenses 03, and fourth lenses 04 are respectively arranged in an annular array on the circumferential surface of the inner wall of the transparent lamp cover 1. The first lenses 01, second lenses 02, third lenses 03, and fourth lenses 04 combine with the transparent lamp cover 1 to form a convex lens structure, and the curvatures of the four are different, and the refraction ranges of light are different. During operation, the staff rotates the sleeve 10, the sleeve 10 drives the transparent lamp cover 1 to rotate, and the transparent lamp cover 1 drives the first lenses 01, second lenses 02, third lenses 03, and fourth lenses 04 to rotate, so that the LED light-emitting component 5 cooperates with the above four different lenses, and the refraction effect of light is different. For example, when the fourth lens 04 rotates to the position opposite to the LED light-emitting component 5, the fourth lens 04 has a larger refraction range for the light emitted by the LED light-emitting component 5 and a wider irradiation area, improving the practicability.

[0041] Embodiment 2:

[0042] Please refer to Figures 1-7 , on the basis of Embodiment 1, the explosion-proof LED tube light has different usage methods;

[0043] The front lamp assembly 2 and the rear lamp assembly 3 can be sleeved with a rubber ring 16, and a magnet 17 is arranged in the rubber ring 16, which can be used to fix the explosion-proof LED tube light on an iron frame. During operation, when the staff uses the explosion-proof LED tube light to provide light, sometimes the staff needs to use tools in their hands and cannot hold the explosion-proof LED tube light. The rubber ring 16 is sleeved on the front lamp assembly 2 and the rear lamp assembly 3, and then it is close to metal objects such as a metal plate or a metal frame nearby. The magnet 17 arranged in the rubber ring 16 firmly adsorbs on the metal object, so that the staff no longer needs to hold the explosion-proof LED tube light, which provides great convenience for the staff.
