[0044] Furthermore, the surfaces of the first pressure ring 33 and the second pressure ring 34 may be provided with an insulating layer, thereby further playing an insulating role and avoiding short circuit.

[0045] Optionally, the battery component 31 and the drive board can be connected by welding or terminal connectors, etc., avoiding the use of wiring connections, so that maintenance personnel do not need to cut the wiring during maintenance, which is not only convenient to operate but also reduces maintenance costs; and because the explosion-proof flashlight 10 is often used in explosion-proof environments such as mines, it has better shock and explosion resistance, avoids the problem of damaging the structure of the explosion-proof flashlight 10 due to accidental cutting, and also avoids the problem of possible safety accidents caused by cutting the wiring in an explosion-proof environment, effectively improving the safety and reliability of the explosion-proof flashlight 10.

The tail cover shell 41 is provided with a mounting through hole. The hard button 43 is arranged in the mounting through hole. The elastic reset member 42 is arranged between the tail cover shell 41 and the hard button 43, and is used to elastically reset the hard button 43 after the hard button 43 is pressed, thereby facilitating the user to press and realize the button control of the explosion-proof flashlight 10.

[0050] Specifically, the hard button 43 may include an axis portion 431 and a pressing portion 432, the axis portion 431 passes through the mounting hole, the first end of the axis portion 431 faces the switch device 6, the second end of the axis portion 431 is connected to one end of the pressing portion 432 (fixed connection or integral connection), and the other end of the pressing portion 432 is exposed outside the tail cover shell 41. The user presses the pressing portion 432, thereby driving the axis portion 431 to move toward the switch device 6 to press the switch device 6, thereby realizing the button control of the explosion-proof flashlight 10; when the user cancels the press, the elastic reset member 42 can drive the hard button 43 to reset.

[0051] Specifically, the elastic reset member 42 may include a washer 421 and a spring 422. The barrel body 2 may be provided with a stop wall for stopping the washer 421 at one end close to the switch device 6. The washer 421 and the spring 422 are sleeved on the hard button 43. The two ends of the washer 421 respectively abut the stop wall and the spring 422. The other end of the spring 422 abuts against the pressing portion 432. When the user cancels the press, the spring 422 provides an elastic force to move the pressing portion 432 away from the switch device 6, thereby driving the hard button 43 to reset.

[0052] Preferably, a second sealing structure 52 may be provided between the shaft portion 431 or / and the pressing portion 432 and the tail cover housing 41, thereby improving the sealing effect of the explosion-proof flashlight 10.

[0053] In practical applications, the explosion-proof flashlight 10 may be provided with a switching module connected to the switch device 6, for switching the working state of the explosion-proof flashlight 10. The switching working state may be as follows: when the hard button 43 is pressed for the first time, the explosion-proof flashlight 10 may illuminate; when the hard button 43 is pressed again, the light of the explosion-proof flashlight 10 may be switched to strong light; when the button is pressed again, the explosion-proof flashlight 10 is turned off, and the switching state may be cycled in this way.

[0054] In actual applications, the hard button 43 can be connected to an indicator light to serve as an indication. When the explosion-proof flashlight 10 is turned on or off, long press the hard button 43 at the tail, and the indicator light source will flash. The number of flashes is the current power status of the lamp, such as: four flashes indicate full power, three flashes indicate 75% power remaining, two flashes indicate 50% power remaining, and one flash indicates 25% power remaining. At this time, the explosion-proof flashlight 10 needs to be charged in time (of course, the present invention can also be provided without an indicator light, and the flashing of the lamp head component 1 can be used directly to serve as an indication). And when the explosion-proof flashlight 10 is lit, the indicator light can also be lit at the same time to indicate the working status of the explosion-proof flashlight 10.

[0055] In some embodiments, see Figures 1 to 9 The explosion-proof flashlight 10 may further include a back clip 7 disposed on the side of the barrel body 2, and one end of the back clip 7 may be fixed by a fastener such as a screw or a screw pin to facilitate the user to carry the explosion-proof flashlight 10.

Therefore, while it is convenient to put the explosion-proof flashlight 10 into the retaining ring 22 from the opening, the retaining ring 22 can also well wrap the explosion-proof flashlight 10 to further improve the fixing effect.

[0060] Optionally, reinforcing ribs 24 may be provided at the connection between the clamping ring 22 and the base 21 and on the surface of the base 21 to strengthen the strength of the clamping ring 22 and the base 21 and improve the service life of the fixing seat 20 .

When in use, the two clamping parts can be moved away from each other first to facilitate the insertion of the explosion-proof flashlight 10, and then the two clamping parts can be moved closer to each other to improve the firmness of the fixation. In this way, it can also adapt to flashlights of different sizes and improve the adaptability of the fixing seat 20.

[0063] In a specific application, the clamp ring 22 can be rotatably connected to the base 21 through a rotating device, so that when the explosion-proof flashlight 10 is fixed, the explosion-proof flashlight 10 can also emit light at a certain angle. In addition, the base 21 can also be provided with a connection device such as a magnetic device, a vacuum adsorption device or a bonding device, which is used to facilitate the connection of the fixing base 20 to various working surfaces such as a pillar or a desktop.

[0064] In specific applications, the explosion-proof flashlight 10 may also include a detector and an alarm. The detector can be used to detect the temperature and air pressure inside the explosion-proof flashlight 10. When the temperature and air pressure inside the explosion-proof flashlight 10 do not meet the preset range, the alarm can directly issue an alarm or send an alarm signal to the driving component 3, thereby allowing the explosion-proof flashlight 10 to emit an alarm indicator light (such as continuously flashing red light, etc.).

[0065] In the present invention, the LED chip 12 is welded to the light source board 11, the lamp head component 1 is connected to the battery of the driving component 3 through the positive elastic member 13 and the negative elastic member 14, and the driving component 32 of the driving component 3 includes a driving board, a connecting spring and a charging spring 321, one end of the connecting spring is connected to the driving board, and the other end is connected to one end of the charging spring 321, and the other end of the charging spring 321 extends from the barrel body 2 or the tail cover component 4 to realize the charging of the drive. The present invention can realize electrical connection without wiring. Therefore, when replacing parts in the explosion-proof flashlight 10, maintenance personnel do not need to cut the wiring, which is not only convenient to operate, but also reduces maintenance costs; and since the explosion-proof flashlight 10 is often used in explosion-proof environments such as mines, the electrical connection method of the present invention has better shock and explosion resistance than wiring. The present invention avoids the problem of damaging the structure of the explosion-proof flashlight 10 due to accidental cutting, and also avoids the problem of possible safety accidents caused by cutting the wiring in the explosion-proof environment, effectively improving the safety and reliability of the explosion-proof flashlight 10.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
