Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to an aluminum alloy headlamp. Background Technology

[0002] Aluminum alloy headlamps are a type of headlamp product that uses aluminum alloy as the material for its shell. Aluminum alloy is highly favored in the headlamp manufacturing industry due to its excellent overall performance. Its low density effectively reduces the overall weight of the headlamp, making it easier for users to wear for extended periods and reducing head strain—a significant advantage in outdoor adventures and long-term nighttime work. At the same time, aluminum alloy possesses good strength and rigidity, offering better resistance to external impacts and pressure compared to plastic materials, greatly improving the headlamp's durability in harsh environments and ensuring normal use under complex working conditions.

[0003] Since aluminum alloy headlamps are generally fitted onto the head with an elastic band, the beam angle cannot be quickly adjusted according to needs, thus failing to meet diverse lighting requirements. In view of the above reasons, this application proposes an aluminum alloy headlamp. Utility Model Content

[0038] Example

[0039] like Figure 1-5 As shown, the present invention proposes an aluminum alloy headlamp, including a bracket 1, on which a lamp body 5 for lighting is movably mounted. The lamp body 5 is provided with a mounting groove 7 for fixing and two annular limiting grooves 6 for connection. The bracket 1 includes a connecting plate 2, which is made of silicone. Two mounting ears 3 are fixedly provided on the front of the connecting plate 2. The mounting ears 3 are provided with mounting holes. A rigid connecting ring 4 is installed on the inner wall of the mounting hole by silicone vulcanization. The rigid connecting ring 4 and the annular limiting grooves 6 are movably connected. The connection method is embedded. A switch 9 and a bottom cover 8 are respectively provided at both ends of the lamp body 5. The bracket 1 is provided with an adjustment structure 10 for adjusting the illumination angle.

[0040] The adjustment structure 10 includes a disc 101 for mounting. The disc 101 and the connecting plate 2 on the bracket 1 are fixedly connected. This solution uses a screw-through fixing method. A connecting rod 102 is movably mounted on the disc 101. A ratchet 103 for locking and a gear 104 for transmission are fixedly mounted on the connecting rod 102. A gear ring 105 meshes with the gear 104. The gear ring 105 is installed in the mounting groove 7 near the bottom cover 8 by brazing. A pawl 106 for locking is provided on one side of the ratchet 103. A rotating shaft 107 is fixed on the back of the pawl 106. A mounting seat 108 is movably mounted on the other end of the rotating shaft 107. A coil spring is fixedly installed inside the disc 108. The inner ring of the coil spring is fixedly sleeved on the rotating shaft 107. A vertical plate 109 is fixedly installed on the front of the disc 101. A pull rod 1010 is movably installed on the vertical plate 109. Two baffles are fixedly installed on the bottom of the pull rod 1010. A spring is sleeved on the pull rod 1010. One end of the spring is in contact with the baffle, and the other end of the spring is in contact with the vertical plate 109. A pull rope is provided at the end of the pull rod 1010 near the pawl 106. The end of the pull rope away from the pull rod 1010 is fixedly connected to the pawl 106. The adjustment structure 10 can realize the rapid adjustment of the illumination angle of the lamp body 5, thereby enabling the equipment to meet diverse lighting needs and improve the practicality of the equipment.

[0041] The lamp body 5 is provided with shock-absorbing structures 11 at both the top and bottom. The shock-absorbing structure 11 includes a mounting tube 111. A vertical rod 112 is provided inside the mounting tube 111. The inner wall of the mounting tube 111 and the outer side of the vertical rod 112 are both provided with threads. The vertical rod 112 and the mounting tube 111 are movably connected. The movably provided vertical rod 112 can adjust the extension length of the hemispherical rubber protrusion 113 according to actual needs. At the same time, the vertical rod 112 can be removed when not in use for easy storage of the equipment. The bottom of the vertical rod 112 is provided with a hemispherical rubber protrusion 113.

[0042] In this embodiment, the rigid connecting ring 4 facilitates the rotation of the lamp body 5. When the illumination angle of the lamp body 5 needs to be lowered, the pull rod 1010 is pulled upwards. The pull rod 1010 drives the pawl 106 to rotate and separate from the ratchet 103. Then, the bottom cover 8 is held and rotated. The bottom cover 8 drives the lamp body 5, and the lamp body 5 rotates on the inner wall of the rigid connecting ring 4, thus adjusting the illumination angle of the lamp body 5. After adjustment, the pull rod 1010 is released, and the spring pushes the baffle to reset the pull rod 1010. The coil spring drives the rotating shaft 107 to reset the pawl 106 and lock it in the tooth groove outside the ratchet 103, achieving unidirectional positioning of the lamp body 5. When the illumination angle of the lamp body 5 needs to be adjusted upward, hold the bottom cover 8 and rotate it clockwise. The bottom cover 8 drives the lamp body 5, which in turn drives the gear ring 105. The gear ring 105 drives the gear 104, which in turn drives the ratchet 103. The tooth groove on the outside of the ratchet 103 moves and separates from the pawl 106. When the next tooth groove reaches the end of the pawl 106, the coil spring causes the pawl 106 to reset and lock in the tooth groove, thus completing the positioning of the lamp body 5. When the headlamp is placed on the platform after use, multiple hemispherical rubber protrusions 113 contact the platform, which can reduce the impact force of the platform on the lamp body 5 and reasonably extend the service life of the equipment.

[0043] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
