Abstract
Description
Technical Field
[0001] This utility model relates to the field of flashlights, specifically a waterproof flashlight structure. Background Technology
[0002] A waterproof flashlight is a lighting tool designed to work reliably in wet or watery environments. Its core strength lies in its precise mechanical structure, which achieves a tight seal. The main components include a corrosion-resistant body, a reliable tail switch seal, and, most importantly, the lamp head: the lamp head typically uses thickened tempered glass as the lens, which is tightly pressed between the metal reflector and the lamp head housing by a rubber O-ring, forming a waterproof barrier. This is then secured with threads, ensuring that even under certain water pressure, moisture can effectively prevent water from penetrating the internal circuitry.
[0003] These flashlights are widely used in various water-related operations, especially at docks, on ships, or during maintenance in coastal areas. The corrosive environment of high salt and humidity requires the flashlights to have excellent waterproof and corrosion-resistant capabilities to ensure that the lighting tools can work continuously and stably when maintenance personnel are inspecting and troubleshooting in complex and humid bilges, decks, or inside equipment, and are not affected by sea splashes or humid air.
[0004] During use and observation, it was found that such maintenance work often involves welding processes such as repairing equipment cracks or cutting components. When maintenance personnel use flashlights to provide close-range illumination to the welding area, the high-temperature molten metal slag that splashes from the welding point is very likely to splash onto the flashlight head glass. This slag will instantly cause erosion of the tempered glass surface, forming permanent scars and pits. This not only seriously scatters light and affects the clarity of the illumination, but also reduces the mechanical strength of the glass, affecting the normal use of the flashlight.
[0005] Therefore, a waterproof flashlight structure is proposed to address the above problems. Utility Model Content

[0023] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0024] Specific implementation examples are given below.
[0025] Please see Figures 1 to 5 As shown in the embodiment of this utility model, a waterproof flashlight structure includes a cylindrical body 1, with a lamp head 12 installed at one end of the cylindrical body 1; a glass 14 is installed inside the lamp head 12; a first ear plate 13 is fixedly connected to the outer wall of the lamp head 12; a second ear plate 16 is provided above the first ear plate 13; a rotating shaft 17 is provided through the first ear plate 13 and the second ear plate 16, the rotating shaft 17 is rotatably connected to the first ear plate 13, and is fixedly connected to the second ear plate 16; a metal mesh 15 is fixedly connected to one side of the second ear plate 16, the metal mesh 15 is used to protect the glass 14; a fixing component for limiting the rotation shaft 17 is provided on the first ear plate 13; when the user is performing maintenance, they can turn on the flashlight switch to make the lamp emit light that penetrates the glass. The illumination beam of 14 provides illumination for maintenance work, such as welding. Before welding begins, the operator can rotate the metal mesh 15 so that it rotates along the first ear plate 13 via the directly connected second ear plate 16 and rotating shaft 17. This rotates the metal mesh 15 to cover the glass 14, and the rotating shaft 17 is limited by the fixing component. At this time, the metal mesh 15 can intercept the high-temperature welding slag that splashes onto the glass 14 through the mesh structure on its surface. At the same time, the mesh structure of the metal mesh 15 can still ensure that some of the illumination beam passes through, which can meet the lighting needs during welding. By setting the metal mesh 15, the metal mesh 15 can protect the glass 14 from the welding slag that splashes during maintenance welding, thereby reducing the erosion or other damage caused by the high-temperature welding slag to the surface of the glass 14.
[0026] Please see Figure 3 and Figure 4As shown, the fixing assembly includes piston chambers symmetrically opened inside the first ear plate 13, with a ball 23 inside the piston chamber and a spring 22 between the ball 23 and the inner wall of the piston chamber; a retaining plate 2 is fixedly connected to the bottom of the rotating shaft 17; the retaining plate 2 has a pair of hemispherical grooves corresponding to the ball 23; when the metal mesh 15 is rotated, the second ear plate 16 can drive the rotating shaft 17 and the retaining plate 2 at the bottom to rotate synchronously until the metal mesh 15 is rotated to coincide with the glass 14. During the process, the retaining plate 2 can apply a lifting effect to the ball 23, so that... The ball 23 slides along the piston cavity and compresses the spring 22. When the metal mesh 15 overlaps with the glass 14, the hemispherical groove on the clamping plate 2 can also overlap with the ball 23. The ball 23 can be embedded in the groove under the elastic force of the spring 22, thereby limiting the clamping plate 2 and its directly connected rotating shaft 17. Through the cooperation of the spring 22 and the ball 23, when the clamping plate 2 rotates to the target position, the ball 23 can be embedded in the surface of the clamping plate 2 under the elastic force of the spring 22, so as to fix the rotating shaft 17 and the metal mesh 15.
[0027] Please see Figure 4 As shown, a connecting rod 3 is fixedly connected to the top of the ball 23; a piston plate 32 is fixedly connected to the top of the connecting rod 3; a limiting plate 33 is fixedly connected to the inner wall of the piston cavity in the first ear plate 13, and the limiting plate 33 is located below the piston plate 32; the top of the piston plate 32 is fixedly connected to the bottom of the spring 22; in the initial state, the spring 22 is in a pre-compressed state, that is, it will apply a downward pressing force to the limiting plate 33, so that the limiting plate 33 can be tightly attached to the piston plate 32, and the piston plate 32 can limit the limiting plate 33, which can ensure that the assembly consisting of the piston plate 32, the connecting rod 3, and the ball 23 can fit into the hemispherical groove on the clamping plate 2 in the initial state, which can make the engagement of the ball 23 with the hemispherical groove on the clamping plate 2 more stable, and can also make the ball 23 more stable when sliding along the piston cavity, reducing the radial shaking of the ball 23 when it moves.
[0028] Please see Figure 2 As shown, a handle 4 is fixedly connected to one side of the metal mesh 15; by setting the handle 4, the user can rotate the metal mesh 15 by turning the handle 4, which improves the convenience of rotating the metal mesh 15.
[0029] Please see Figure 1 and Figure 5 As shown, the outer wall of the cylinder 1 is fitted with a rubber sleeve 5; by setting the rubber sleeve 5, the rubber sleeve 5 can provide additional protection for the outer surface of the cylinder 1, so as to reduce its direct contact with water vapor in the air in the working environment near water, and also reduce the oil stains and other impurities adhering to the surface of the cylinder 1 due to maintenance, thus extending the service life of the cylinder 1.
[0030] Please see Figure 5As shown, the outer wall of the cylinder 1 is provided with a groove 6; the surface of the rubber sleeve 5 is fitted with a clamp 62 by bolts; the rubber sleeve 5 is located between the groove 6 and the clamp 62; by pre-setting the groove 6 on the cylinder 1, the rubber sleeve 5 can be installed and removed from the cylinder 1 by the clamp 62, which facilitates the replacement or cleaning of the rubber sleeve 5.
[0031] Working principle: During maintenance, the user can turn on the flashlight switch to emit a beam of light that penetrates the glass 14, providing illumination for the maintenance work. Specifically, for welding work, before starting the welding operation, the user can rotate the metal mesh 15. This rotates the metal mesh 15 along the first ear plate 13 via the directly connected second ear plate 16 and rotating shaft 17, rotating the metal mesh 15 to cover the glass 14. The rotating shaft 17 is then limited by a fixing component. At this time, the metal mesh 15 can intercept high-temperature welding slag that splashes onto the glass 14 through its mesh structure. The mesh structure of the metal mesh 15 still ensures that some lighting beams can pass through, meeting the lighting requirements during welding. When rotating the metal mesh 15, the second ear plate 16 drives the rotating shaft 17 and the bottom clamping plate 2 to rotate synchronously until the metal mesh 15 is rotated to coincide with the glass 14. During this process, the clamping plate 2 can apply a lifting effect to the ball 23, causing the ball 23 to slide along the piston cavity and compress the spring 22. When the metal mesh 15 coincides with the glass 14, the hemispherical groove on the clamping plate 2 can also just overlap with the ball 23, and the ball 23 can be embedded under the elastic force of the spring 22. The ball 23 is inserted into the groove, thereby limiting the position of the locking plate 2 and its directly connected rotating shaft 17. In the initial state, the spring 22 is in a pre-compressed state, which applies a downward pressing force to the limiting plate 33, so that the limiting plate 33 can be tightly attached to the piston plate 32. The piston plate 32 can limit the position of the limiting plate 33, thus ensuring that the assembly consisting of the piston plate 32, connecting rod 3, and ball 23 can be perfectly engaged with the hemispherical groove on the locking plate 2 in the initial state. This makes the engagement of the ball 23 with the hemispherical groove on the locking plate 2 more stable, and also makes the ball 23 more stable when sliding along the piston cavity, reducing the radius of the ball 23 during movement. The metal mesh 15 can be rotated by the user by the handle 4, which improves the convenience of rotating the metal mesh 15. The rubber sleeve 5 provides additional protection for the outer surface of the cylinder 1, reducing direct contact between it and water vapor in the working environment near water. It also reduces oil stains and other impurities adhering to the surface of the cylinder 1 during maintenance, thus extending the service life of the cylinder 1. The groove 6 pre-set on the cylinder 1 allows the rubber sleeve 5 to be installed and removed from the cylinder 1 by the clamp 62, which facilitates the replacement or cleaning of the rubber sleeve 5.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
