[0029] The utility model discloses a mine lamp sealing structure as shown in Figures 1-6 、 Figure 13 It includes lamp shell 1, the light cup 2 of being located in lamp shell 1, the main control board 3 of being located light cup 2 after, the front end cover 4 of being located in lamp shell 1 front end, the key structure 5 of being located in lamp shell 1 both sides, horn cover plate 6 and camera 7. Different from prior art, the first sealing ring 12 of corresponding shape between front end cover 4 and lamp shell 1, through several bolts 15a from front to back through front end cover 4, first sealing ring 12 and lamp shell 1 are connected and fixed. Such structure, compared with the thread screw connection of traditional front end cover 4 and lamp shell 1, the connection sealing of the utility model is more firm and effective.

[0030] And, the front end cover 4 has the lamp head transparent window 13, and the resin lens 24a with the light transmittance greater than 95% is arranged in the window 13, and the window 13 is sealed by interference fit and glue. Compared with glass, it can reduce the overall weight of the lamp head, and is convenient to wear. The positioning ring 14 is sleeved on the conical light cup 2, and the inner diameter of the positioning ring 14 is less than the maximum diameter of the front end of the light cup 2, and the positioning ring 14 has a protruding connecting plate on each side, and a bolt hole is arranged on the connecting plate. The bolt 15b is connected and fixed with the screw hole 17 of the front end cover 4 from back to front, so that the light cup 2 is positioned between the positioning ring 14 and the lamp head transparent window 13. Specifically, the silica gel ring 27 can be sleeved on the front edge of the light cup 2, and the silica gel ring 27 is clamped between the resin lens 24a and the positioning ring 14. Since the light cup 2 is arranged in the form of hoisting, the light cup 2 cannot fall backward, and the light cup 2 does not directly contact the lamp shell 1 and the front end cover 4, so that even if the mine lamp collides or falls, the light cup 2 will not be deformed or deviated.

[0031] In addition, the front surface of the front end cover 4 is provided with a decorative plate 16 to cover the bolts 15a for aesthetic purposes.

[0032] Please refer to Figure 1 、 Figures 7-12 The key structure 5 includes a key installation window formed on one side of the lamp shell 1, a key circuit board 18 arranged in the installation window, and an integrated key cover plate 19 arranged on the installation window. The key cover plate 19 is provided with a plurality of functional key sheaths 20, which are formed integrally with the key cover plate 19 by secondary injection molding. One end of the functional key sheath 20 is connected to a corresponding key contact 21 arranged on the key circuit board 18, and the key circuit board 18 is electrically connected to the main control board 3. Moreover, the inner edge of the key installation window is provided with a concave step 23, and a second sealing ring 22 corresponding in shape is arranged between the key installation window and the key cover plate 19. The key cover plate 19 and the second sealing ring 22 are connected and fixed to the step 23 of the key installation window by a plurality of bolts 15c from the outside to the inside. The outer edge of the key circuit board 18 is slightly smaller than the step 23 of the key installation window, and is connected and fixed to the key cover plate 19 by a plurality of bolts 15d from the inside to the outside. Since the key circuit board 18 is independent, if the key needs to be replaced due to failure, the main control board 3 (the key contact 21 of the prior art is located on the main control board 3, and there is no special key circuit board) does not need to be disassembled, making maintenance more convenient. Moreover, the second sealing ring 22 is provided, and the sealing and waterproof effect is better. In addition, the key circuit board 18 is directly connected to the key cover plate 19, and the key is not easy to loosen and deviate.

[0033] However, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application, and are not used as a limitation of the present application. As long as the changes and modifications of the above described embodiments are within the scope of the essential spirit of the present application, they will fall within the scope of the claims of the present application.
