Description

Technical Field

[0001] This utility model belongs to the field of mining headlamps, and in particular relates to a mining headlamp with adjustable brightness. Background Technology

[0002] A mining headlamp is a special lighting fixture designed to provide illumination for miners working underground. Due to the complex and dimly lit environment of mines, the headlamp frees up miners' hands, making it easier for them to perform operations such as digging, carrying, and equipment inspection. It typically uses light-emitting diodes (LEDs) as the light source. The brightness of a mining headlamp can be adjusted by rotating the lamp head or by using a mechanical knob on the headlamp. By rotating the knob at different angles, the resistance in the circuit can be changed, thereby adjusting the brightness. This mechanical adjustment method is relatively simple and direct, and easy to operate.

[0003] In existing technologies, after a period of use, the internal electronic components of a headlamp inevitably suffer damage. If the internal electronic components are damaged, the headlamp housing needs to be disassembled to repair or replace the internal components. However, the headlamp housings are usually connected by screws, so appropriate screwdrivers and other tools are required when disassembling and assembling the housings. Furthermore, if the screws are not properly stored after removal, they may be lost due to their small size. If screws are lost, it may affect the subsequent connection between the housings. To address these issues, we provide an adjustable brightness mining headlamp. Utility Model Content

[0004] The purpose of this invention is to provide a mining headlamp with adjustable brightness, which eliminates the need for screws to disassemble and assemble the outer casings, and also eliminates the need for screws to fix the outer casings together.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an adjustable brightness mining headlamp, including a rear lamp housing, a connecting structure, a fixing structure, a positioning structure, and a docking structure; the connecting structure on the rear lamp housing includes a protective shell on the rear lamp housing, a lampshade threadedly connected to the protective shell, a recessed block fixedly connected to the rear lamp housing, two connecting shafts rotatably connected to the inner surface of the recessed block, a movable block fixedly connected to the two connecting shafts, and a fixing structure on the movable block; the positioning structure on the recessed block includes a positioning groove formed in the recessed block, a positioning block movably connected to the inner surface of the positioning groove, and a bearing block fixedly connected to the front surface of the positioning block and fixedly connected to the protective shell.

[0007] The present invention is further configured such that the fixing structure includes a guide rod fixedly connected to the inner wall of the movable block, two sliders slidably connected to the outer surface of the guide rod, two fixing blocks respectively fixedly connected to the front surface of the sliders, limiting grooves respectively opened on the two fixing blocks, and two limiting blocks respectively movably connected to the inner surface of the limiting grooves.

[0008] The present invention is further configured such that a spring is slidably sleeved on the outer surface of the guide rod, and the two ends of the spring are respectively fixedly connected to two corresponding sliders, which enables the limiting groove to be quickly inserted into the limiting block.

[0009] The present invention is further configured such that a groove is provided on the movable block for sliding connection with the slider, and the guide rod passes through the slider to restrict the movement direction of the slider, so that the slider moves more smoothly.

[0010] The present invention is further configured such that the side surface of the limiting block is fixedly connected to the bearing block.

[0011] The present invention is further configured such that the outer surface of the movable block is in contact with the concave block, and the number of the connecting structures is two and they are symmetrically distributed.

[0012] The present invention is further configured such that the number of the fixing structures is two and they are symmetrically distributed, and the number of the positioning structures is four and they are distributed in a rectangular array.

[0013] The present invention is further provided that the rear lamp housing is provided with a docking structure, the docking structure including a connecting plate fixedly connected to the rear surface of the rear lamp housing and two connecting slots opened on the connecting plate. Through the reserved connecting slots, the entire device can be docked with other objects.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through the setting of structures such as fixing blocks, limiting grooves, and limiting blocks, allows the fixing between the rear lamp housing and the protective housing to be released by operating the fixing blocks, thereby separating the rear lamp housing and the protective housing. After the rear lamp housing and the protective housing are separated, the internal electronic components of the headlamp can be repaired or replaced. After the repair or replacement is completed, the limiting groove is reinserted into the limiting block to complete the connection and fixation between the rear lamp housing and the protective housing. The disassembly and assembly of the rear lamp housing and the protective housing can be achieved without the use of tools, and there is no need to use screws to fix the rear lamp housing and the protective housing, avoiding the problem of missing screws affecting the installation of the rear lamp housing and the protective housing later, which is convenient and quick.

[0016] 2. By setting up a positioning groove and positioning block, this utility model allows the positioning block to be inserted into the positioning groove first when installing the rear light housing and the protective housing. This not only achieves the initial connection between the rear light housing and the protective housing, but also eliminates the need for manual positioning and alignment between the rear light housing and the protective housing, thus facilitating subsequent work for the operator and saving time and effort.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation

[0027] like Figures 1-5 As shown, this utility model is a mining headlamp with adjustable brightness, including a rear lamp housing 1, a connecting structure, a fixing structure, a positioning structure, and a docking structure.

[0028] like Figures 1-5 As shown, the connection structure set on the rear lamp housing 1 includes a protective shell 2 set on the rear lamp housing 1, a lamp cover 3 threadedly connected to the protective shell 2, a recess 4 fixedly connected to the rear lamp housing 1, two connecting shafts 5 rotatably connected to the inner surface of the recess 4, a movable block 6 fixedly connected to the two connecting shafts 5, and a fixing structure set on the movable block 6. The outer surface of the movable block 6 is in contact with the recess 4. There are two connection structures and they are symmetrically distributed.

[0029] The fixed structure includes a guide rod 7 fixedly connected to the inner wall of the movable block 6, two sliders 8 slidably connected to the outer surface of the guide rod 7, two fixing blocks 9 respectively fixedly connected to the front surface of the sliders 8, limiting grooves 10 respectively opened on the two fixing blocks 9, and two limiting blocks 11 respectively movably connected to the inner surface of the limiting grooves 10. A spring 15 is slidably sleeved on the outer surface of the guide rod 7. The two ends of the spring 15 are respectively fixedly connected to the two corresponding sliders 8. A sliding groove 16 is opened on the movable block 6 to slide and connect with the slider 8. The guide rod 7 passes through the slider 8. The side surface of the limiting block 11 is fixedly connected to the bearing block 14. There are two fixed structures and they are symmetrically distributed.

[0030] In this embodiment, when it is necessary to repair or replace the electronic components inside the headlamp, by simultaneously pressing the two corresponding fixing blocks 9, the two fixing blocks 9 are moved closer to each other. This causes the moving fixing blocks 9 to drive the limiting groove 10 and the slider 8 to move. During the movement of the slider 8 on the guide rod 7, it gradually compresses the spring 15, keeping the spring 15 in a taut state. When the moving limiting groove 10 disengages from the limiting block 11, the restriction on the movable block 6 and the structure on the movable block 6 is released. Then, the fixing block 9 is flipped, allowing the movable block 6 and the structure on the movable block 6 to flip around the connecting shaft 5 as the central axis. During the flipping process of the movable block 6... The middle will drive the connecting shaft 5 to rotate. When the fixed block 9 flips to the other side and no longer corresponds to the limiting block 11, the fixed block 9 is released, and the spring 15 is no longer compressed and rebounds. The rebounding spring 15 can drive the two sliders 8 to move away from each other, so that the moving sliders 8 can drive the fixed block 9 to move. Then, the above operation is repeated on the other side to release the fixation between the rear lamp housing 1 and the protective housing 2. Then, after pulling the protective housing 2, the protective housing 2 and the structure on the protective housing 2 can be removed from the rear lamp housing 1 and the structure on the rear lamp housing 1. After the disassembly work between the lamp housing 1 and the protective housing 2 is completed, the electronic components inside the headlamp can be repaired or replaced. Specific Implementation

[0031] like Figures 1-5 As shown, this utility model is a mining headlamp with adjustable brightness. Compared with the first embodiment, in this embodiment, the positioning structure set on the recess 4 includes a positioning groove 12 opened on the recess 4, a positioning block 13 movably connected to the inner surface of the positioning groove 12, and a bearing block 14 fixedly connected to the front surface of the positioning block 13 and fixedly connected to the protective shell 2. The number of positioning structures is four and they are distributed in a rectangular array.

[0032] In this embodiment, after the electronic components of the headlamp are repaired or replaced, the positioning block 13 is inserted into the positioning groove 12. This not only enables the initial installation between the rear lamp housing 1 and the protective housing 2, but also eliminates the need for further alignment and positioning between the rear lamp housing 1 and the protective housing 2. Then, the corresponding two fixing blocks 9 are pressed simultaneously, causing the moving fixing block 9 to move the limiting groove 10 and the slider 8 while keeping the spring 15 taut. When the moving fixing block 9 no longer affects the rotation of the movable block 6 due to the limiting block 11, it flips in the opposite direction and is fixed. Block 9 allows the movable block 6 and the structure on the movable block 6 to be flipped in the opposite direction. When the flipped limiting groove 10 corresponds to the limiting block 11, the fixing block 9 is released, so that the spring 15 is no longer compressed and rebounds. The rebounding spring 15 can drive the slider 8, the fixing block 9 and the limiting groove 10 to move back to their original positions. After the moving limiting groove 10 is inserted into the limiting block 11, the above operation is performed again on the other side to fix the movable block 6 and the structure on the movable block 6, thereby completing the fixation between the lamp housing 1 and the protective housing 2.

Compared with Embodiment 1, in this embodiment, the rear lamp housing 1 is provided with a docking structure. The docking structure includes a connecting plate 17 fixedly connected to the rear surface of the rear lamp housing 1 and two connecting grooves 18 opened on the connecting plate 17.

[0034] In this embodiment, the device as a whole can be connected to the connecting base or other objects through the connecting groove 18 reserved on the connecting plate 17.
