It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0016] Reference Figures 1 to 4 As shown, in order to achieve the above purpose, the utility model provides the following technical solutions: an intrinsically safe mining lamp, comprising a battery box 1, a lamp holder 2 and a cable 3, the battery box 1 is connected to the lamp holder 2 through the cable 3, the battery box 1 comprises an outer shell 11 and an inner shell 12, the inner shell 12 is detachably installed in the outer shell 11, and is detachably connected to the outer shell 11;

[0017] A lithium manganese oxide battery or a lithium iron phosphate battery is installed in the inner shell 12, and a conductive agent is arranged on the lithium manganese oxide battery or the lithium iron phosphate battery.

[0018] The design of the utility model has the following advantages: 1. By adopting lithium manganate or lithium iron phosphate batteries and designing two layers of inner and outer shells 11, the batteries and related protection circuits are encapsulated in the inner shell 12, thereby improving the safety performance of the mining lamp.

[0019] 2. The battery prevents high temperature and explosion caused by internal short circuit by adding conductive agents, improving reaction depth and utilization rate, and ensuring the safety and stability of the battery.

[0020] The upper end of the housing 11 is provided with a wire outlet hole 13 for the cable 3 to pass through, and a conductive sleeve 14 is provided outside the wire outlet hole 13 , and a wire outlet angle of 45° is formed between the conductive sleeve 14 and the upper end of the housing 11 .

[0021] It also includes a clamping member 4, which is detachably connected to the lamp holder 2.

[0022] The card member 4 is made of plastic material, which reduces the use cost and facilitates the use and replacement of the card member 4.

[0023] The clamping member 4 is provided in an annular structure, and two clamping grooves 41 are symmetrically provided on the clamping member 4 .

[0024] Two elastic hooks 42 are symmetrically arranged on the clamping member 4 .

[0025] As shown in the figure, the card slot 41 is engaged with the card block on the lamp holder 2, and the elastic card hook 42 is matched with the embedded slot in the lamp holder 2, so that the card member 4 can be easily and quickly installed in the lamp holder 2 with stable force.

[0026] The clamp 4 is provided with a first lamp bead slot 43 , a second lamp bead slot 44 and a third lamp bead slot 45 equidistantly arranged in sequence. The first lamp bead slot 43 and the third lamp bead slot 45 are square slots, and the second lamp bead slot 44 is a circular slot.

[0027] The design of this structure can be applicable to a variety of different lamp beads in the lamp holder 2, thereby improving the application range of the equipment.

[0028] Furthermore, the clamping member 4 is provided with a snap-fitting groove 46 for connecting the first lamp bead groove 43, the second lamp bead groove 44 and the third lamp bead groove 45, and a snap-fitting pad is detachably installed in the snap-fitting groove 46.
