Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to an adjustment structure for industrial and mining lamps. Background Technology
[0002] Industrial and mining lamps are lighting fixtures specifically designed for special locations such as factory workshops and warehouses. These lamps are characterized by high brightness, high efficiency, high temperature resistance, and corrosion resistance, enabling them to operate stably in harsh environments and ensuring production safety and efficiency. PC sheets, also known as polycarbonate sheets, are high-performance thermoplastic polymers with good transparency, impact resistance, and stability. They are typically used as lamp covers or light-transmitting components in industrial and mining lamps, protecting the internal bulb and circuitry while ensuring sufficient light transmission.
[0003] To maintain stable operation in harsh environments, industrial and mining lamps are typically directional, reducing light loss and improving lighting efficiency. However, adjusting the lighting angle after installation is inconvenient and cumbersome. In certain situations where different angles are required, existing industrial and mining lamps struggle to adjust the beam angle. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide an adjustment structure for industrial and mining lamps, which can easily adjust the illumination angle of the lamps, provide a wider illumination range, and meet different lighting needs.
[0005] An adjustment structure for an industrial and mining lamp includes a lamp body shell, a side cover, a rotating shaft, and a PC board. The lamp body shell has an opening on its side, and the side cover covers this opening. The rotating shaft is located inside the lamp body shell near the side opening and is connected to the side cover. The PC board is located inside the lamp body shell. A fixing member is fitted onto the rotating shaft and is fixedly connected to the lamp body shell. A damping member is also fitted onto the rotating shaft, abutting against the fixing member to generate damping through friction when the rotating shaft rotates. The side cover can rotate around the rotating shaft to open the side opening of the lamp body shell and replace the PC board.
[0006] The adjustment structure for industrial and mining lamps described in this utility model features a rotating shaft with damping and positioning functions. This allows the side cover of the lamp to be rotated open. The opened side cover is then fixed in place by the damping action of the rotating shaft, facilitating operation. When the side cover is closed, the damping and positioning function of the rotating shaft ensures that the side cover fits snugly against the lamp body, preventing internal interference and ensuring the overall stability of the lamp. By replacing the plates with different beam angles, the industrial and mining lamp can have a wider range of illumination angles and coverage to meet various lighting needs.
[0007] Furthermore, the side cover is provided with an extension portion extending toward the interior of the lamp housing; the extension portion is provided with a groove for accommodating the rotating shaft.
[0008] Furthermore, an upper cover is provided on the extension of the side cover, the upper cover is placed on the extension, and a through hole is provided for fixed connection with the extension.
[0009] Furthermore, one end of the rotating shaft is configured as a cuboid structure with an arc-shaped side, wherein the width of the arc is smaller than the width of the rectangle; the width of the groove near the cuboid structure of the rotating shaft is set slightly larger than the width of the arc of the cuboid structure of the rotating shaft, and the cuboid structure of the rotating shaft is fitted into the groove.
[0010] Furthermore, an opening is provided on one side of the lamp housing. When opening the side cover 2 and replacing the PC board, the operation is carried out through only one opening, ensuring the overall stability of the industrial lamp.
[0011] Furthermore, the lamp body outer shell has openings on both sides of the central axis, and a PC board is installed in each of the two openings. The independent PC boards on both sides of the industrial lamp further enhance the versatility of the illumination angle and range.
[0012] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings. Attached Figure Description

[0018] The adjustment structure of this industrial and mining lamp includes a lamp body shell 1, a side cover 2, a rotating shaft 3, and a PC board. The lamp body shell 1 has an opening on its side, and the side cover 2 covers this opening. The rotating shaft 3 is located inside the lamp body shell 1 near the side opening and is connected to the side cover 2. The PC board is located inside the lamp body shell 1. When the side cover 2 is opened, the damping of the rotating shaft 3 fixes the side cover, facilitating the replacement of the PC board inside the lamp body shell 1. By replacing the PC board with one of different beam angles, the illumination angle and range can be changed, providing a wider range of illumination angles and ranges to meet different lighting requirements.
[0019] One end of the rotating shaft 3 is configured as a cuboid structure with an arc-shaped side, wherein the width of the arc is smaller than the width of the rectangle; the other end of the rotating shaft 3 is configured as a hexagonal head structure, forming a regular hexagon. A fixing member 31 is fitted in the middle of the rotating shaft 3, the fixing member 31 extending in a direction perpendicular to the rotating shaft 3, and the fixing member 31 has a through hole for fixed connection with the lamp body housing 1. The rotating shaft 3 can rotate relative to the fixing member 31; a damping member 32 is also fitted near the middle of the rotating shaft 3, the damping member 32 abutting against the fixing member 31. When the rotating shaft 3 rotates, the damping member 32 rubs against the fixing member 31, providing damping for the rotating shaft 3, so that the rotating shaft 3 can be fixed.
[0020] The side cover 2 has an extension 21 extending toward the interior of the lamp housing 1. The extension 21 has a groove for accommodating the rotating shaft 3. The width of the groove near the cuboid end of the rotating shaft 3 is slightly larger than the arc width of the cuboid structure of the rotating shaft 3, and the cuboid structure of the rotating shaft 3 is engaged within the groove. When the side cover 2 is opened, the extension 21 rotates, and the groove abuts against the cuboid structure of the rotating shaft 3, causing the rotating shaft 3 to rotate. The extension 21 of the side cover 2 also has an upper cover 22, which covers the extension 21 and has a through hole for fixed connection with the extension 21, enclosing the rotating shaft 3 within the extension 21 to prevent external interference.
[0021] The lamp housing 1 is a common type of lamp housing 1 in the prior art. Specifically, one side of the lamp housing 1 is provided with an opening, so that when opening the side cover 2 and replacing the PC board, the operation can be carried out through only one opening, ensuring the overall stability of the industrial and mining lamp; the lamp housing 1 is provided with openings on both sides of the central axis, so that PC boards with different light distribution angles can be replaced by inserting PC boards into the two openings, thus providing a wider range of illumination angles and illumination ranges.
[0022] During use, when the industrial and mining lamp needs to change the illumination angle or illumination range, the side cover 2 is opened, the extension 21 rotates, the groove abuts against the rotating shaft 3, and drives the rotating shaft 3 to rotate; when the rotating shaft 3 rotates, the damping element 32 on the rotating shaft 3 rubs against the fixing element 31 to provide damping, so that the side cover 2 can be fixed after opening, which is convenient for replacing the PC board; after replacing the PC board, the side cover 2 is closed, and the damping positioning function of the rotating shaft 3 makes the side cover 2 fit tightly against the lamp body shell 1.
[0023] The adjustment structure of this industrial and mining lamp utilizes a rotating shaft with damping and positioning functions. This allows the side cover 2 of the lamp to be rotated open. The opened side cover 2 is then secured by the damping action of the rotating shaft 3, facilitating operation. When the side cover 2 is closed, the damping and positioning function of the rotating shaft 3 ensures it fits snugly against the lamp housing 1, preventing internal interference and ensuring overall stability. By replacing the PC boards with different beam angles, the industrial and mining lamp can achieve a wider range of illumination angles and ranges to meet diverse lighting needs. The independent PC boards on both sides of the lamp further enhance the versatility of the illumination angle and range options.
[0024] The embodiments described above are merely examples of several implementations of the utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
