For example, they can be fixedly connected, detachably connected, or connected in an integral manner; they can be mechanically connected or electrically connected; they can be directly connected, indirectly connected through an intermediate medium, or they can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The following describes the embodiments of the present invention based on its overall structure.

[0025] Reference Figures 1 to 6In an embodiment of the utility model, a flameproof LED bracket lamp for mining includes: a bracket lamp housing 1, a driving motor 6 is fixedly connected to the side of the bracket lamp housing 1, a first gear 7 is fixedly connected to the rotating shaft of the driving motor 6, an LED lamp bead 8 is arranged below the bracket lamp housing 1, a rotating outer sleeve 9 is rotatably connected to the bottom of the bracket lamp housing 1, a second gear 10 is fixedly connected to the outside of the rotating outer sleeve 9, the second gear 10 is meshed with the first gear 7, a guide inclined groove 11 is opened on the outside of the rotating outer sleeve 9, and a lens fixing mechanism 12 is arranged on the inside of the rotating outer sleeve 9;

[0026] The lens fixing mechanism 12 includes an upper clamping ring 121, a lower clamping ring 122 is provided below the upper clamping ring 121, a metal protective cover 123 is fixedly connected below the lower clamping ring 122, a focusing convex lens 124 is provided between the upper clamping ring 121 and the lower clamping ring 122, an internal thread is provided on the inner side of the upper clamping ring 121, and an external thread adapted to the internal thread is provided on the outer side of the lower clamping ring 122, and the upper clamping ring 121 and the lower clamping ring 122 are threadedly connected. With this design, the focusing convex lens 124 can be easily assembled and disassembled. 24. Two sets of spring grooves 125 are symmetrically provided on the outer side of the upper clamping ring 121. A supporting spring 126 is fixedly connected to the inner side of the spring groove 125. The other end of the supporting spring 126 is fixedly connected to a positioning slider 127. The positioning slider 127 is adapted to the guide inclined groove 11. A limiting rod 128 is fixedly connected to the top of the upper clamping ring 121. A limiting hole adapted to the limiting rod 128 is provided at a corresponding position below the bracket lamp housing 1, so that the lens fixing mechanism 12 will not rotate with it when the inner side of the outer sleeve 9 is rotated.

[0027] The above scheme is adopted: the first gear 7 can be driven to rotate by driving the motor 6, and the first gear 7 is engaged with the second gear 10, and the rotating outer sleeve 9 fixedly connected to the second gear 10 on the outside will also rotate. When the rotating outer sleeve 9 rotates, the two sets of positioning sliders 127 slide on the inside of the corresponding guide bevel 11, and because of the action of the limit rod 128, the lens fixing mechanism 12 on the inside of the rotating outer sleeve 9 will not rotate therewith, so it will drive the focusing convex lens 124 to move up and down together, thereby adjusting the distance between the focusing convex lens 124 and the LED lamp bead 8.

[0028] Reference Figure 1 and Figure 5 A hanging hook 2 is fixedly connected to the top of the bracket lamp housing 1, and two groups of side fixed blocks 3 are symmetrically fixedly connected to the side of the bracket lamp housing 1. The outer sides of the two groups of side fixed blocks 3 are rotatably connected to a rotating handle fixing plate 4. There are multiple groups of fixing holes above the rotating handle fixing plate 4. A protective shell 5 is provided under the bracket lamp housing 1 to isolate external dust. A card slot is provided on the outside of the side fixed card block 3, and a card block adapted to the card slot provided on the outside of the side fixed card block 3 is fixedly connected to the inside of the protective shell 5.

[0029] Adopting the above solution: when the bracket lamp needs to be fixed, the bracket lamp can be hung at a designated position using the hanging hook 2, or the bracket lamp can be fixed to the wall by passing a screw through the fixing hole provided on the rotating handle fixing plate 4.

[0030] The working principle of the utility model is as follows: a hanging hook 2 is provided above the bracket lamp housing 1, which can be used to hang the bracket lamp in a mine or other designated location; a side fixing block 3 and a rotating handle fixing plate 4 are provided on the side of the bracket lamp housing 1; the rotating handle fixing plate 4 is provided with multiple sets of fixing holes, which can be used to fix the bracket lamp on a wall or other flat surface using screws;

[0031] When the driving motor 6 is started, its rotating shaft drives the first gear 7 to rotate. Since the first gear 7 is meshed with the second gear 10, the rotating outer sleeve 9 fixedly connected to the second gear 10 on the outside will rotate accordingly. When the rotating outer sleeve 9 rotates, the positioning slider 127 will slide along the guide inclined groove 11 provided on the outside of the rotating outer sleeve 9. Since the limiting rod 128 is inserted into the limiting hole on the bracket lamp housing 1, the rotation of the lens fixing mechanism 12 is limited so that the lens fixing mechanism 12 can only move up and down. As the lens fixing mechanism 12 moves up and down, the height of the focusing convex lens 124 also changes accordingly, thereby adjusting the distance between the focusing convex lens 124 and the LED lamp bead 8. This adjustment allows the focal length of the light beam to be adjusted to achieve different lighting effects, such as focusing or astigmatism.

[0032] The focusing convex lens 124 is easily worn or broken during long-term use. When the focusing convex lens 124 needs to be replaced, it is only necessary to remove the protective shell 5 that is engaged with the side fixed block 3, squeeze the locking slider 127 inward to make it completely retract into the spring groove 125, and release the engagement between the locking slider 127 and the guide inclined groove 11. At this time, the lens fixing mechanism 12 can be gently pulled downward to remove it. After the lens fixing mechanism 12 is removed, the upper clamping ring 121 and the lower clamping ring 122 that are tightly threaded are unscrewed to remove the focusing convex lens 124 to be replaced. After replacing the new focusing convex lens 124, the lens fixing mechanism 12 and the protective shell 5 can be reinstalled.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
