Description

Technical Field

[0001] This utility model relates to the field of flashlight technology, and in particular to an installation structure for a high-intensity bulb in an aluminum alloy flashlight. Background Technology

[0002] A flashlight is a handheld electronic lighting tool. A typical flashlight has a battery-powered bulb and a focusing reflector, and a handle-type casing for holding. Although it is a fairly simple design, it was not invented until the late 19th century because it required the invention of both the battery and the light bulb.

[0003] In existing technologies, such as the flashlight bulb mounting structure disclosed in patent CN222703116U, the core of the structure uses a traditional threaded connection combined with a single snap-fit ​​fixing method. The threaded connection relies on the mechanical engagement between the threads, which, under prolonged outdoor exposure to bumps, vibrations, or frequent drops, is prone to loosening due to accumulated thread clearance. Furthermore, the single snap-fit ​​structure is susceptible to material fatigue; after repeated disassembly and reassembly, the locking force gradually diminishes, making it difficult to consistently provide stable clamping force. This fixing method is not only structurally simple but also lacks anti-loosening buffer components, which can lead to problems when the flashlight is used for outdoor exploration or work. When encountering continuous vibrations in scenarios such as process operations, the contact points between the high-intensity bulb and the lamp holder are prone to intermittent detachment. This manifests as flickering lighting, sudden drops in brightness, or even complete extinguishing, affecting work efficiency and potentially posing safety hazards in emergency situations. Furthermore, poor contact due to loosening increases circuit impedance, exacerbates power loss, and further shortens the flashlight's battery life. Frequent contact sparks can also accelerate oxidation of the lamp holder contacts, shortening the overall lifespan. Therefore, designing an installation structure for the high-intensity bulb in an aluminum alloy flashlight has become a problem we need to solve. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: an installation structure for a high-intensity bulb in an aluminum alloy flashlight, comprising a barrel body and a lampshade disposed on the barrel body; a lamp holder is disposed inside the lampshade, a high-intensity bulb is threadedly connected inside the lamp holder, a spring is fixedly installed inside the lamp holder, a movable block is fixedly installed at one end of the spring, a pull rod is fixedly passed through the movable block, a vertical plate is fixedly installed at one end of the pull rod, and one end of the vertical plate extends through to the outside of the lamp holder and is fixedly connected to an arc-shaped plate adapted to the high-intensity bulb;

[0005] The outer surface of the lamp holder has a concave cavity. A compression frame is slidably connected inside the concave cavity of the lamp holder. A pull rope is fixedly installed on the inner wall of the compression frame. A pulley is rotatably connected to the inner wall of the concave cavity of the lamp holder. The pull rope slides around the surface of the pulley. The end of the pull rod away from the vertical plate passes through the concave cavity and is connected to the pull rope.

[0006] With the above technical solution, when it is necessary to install a high-intensity bulb, pressing the squeezing frame causes the pull rope to pull the lever. The lever drives the vertical plate and the arc plate to move synchronously and compress the spring. At this time, an installation space is formed between the arc plate and the lamp holder. After the high-intensity bulb is threaded into the lamp holder, the squeezing frame is released. The spring returns to its original position and pushes the moving block and the lever to move in the opposite direction. The vertical plate drives the arc plate to fit tightly against the surface of the high-intensity bulb, achieving stable clamping. When disassembling, pressing the squeezing frame again separates the arc plate from the bulb, and the bulb can be unscrewed. The operation is convenient.

[0007] As an improvement to the above technical solution, rubber anti-slip strips are symmetrically installed on the outer surface of the cylinder.

[0008] Through the above technical solution, the rubber anti-slip strip can increase the friction when the user holds the flashlight, prevent the flashlight from slipping, and improve the safety of use.

[0009] As an improvement to the above technical solution, a first slider is fixedly installed on both opposite sides of the moving block, and a first groove adapted to the first slider is opened inside the lamp holder.

[0010] Through the above technical solution, the first slider slides in the first groove, which can guide the movement of the moving block, ensure that the moving block drives the pull rod to move smoothly, and make the clamping of the high-intensity light bulb by the arc plate more stable.

[0011] As an improvement to the above technical solution, an anti-slip rubber pad is fixedly installed on the outer side of the extrusion frame.

[0012] Through the above technical solution, the anti-slip rubber pad can increase the friction of the user's hand when pressing the squeeze frame, making it easier to operate, while avoiding direct contact between the hand and the squeeze frame, which would cause wear.

[0013] As an improvement to the above technical solution, both the cylinder body and the lampshade are made of aluminum alloy.

[0014] Through the above technical solutions, aluminum alloy material has the characteristics of being lightweight, high-strength, and having good thermal conductivity. It can not only reduce the overall weight of the flashlight, but also facilitate the conduction of heat generated by the high-intensity bulb, further improving the heat dissipation effect.

[0015] As an improvement to the above technical solution, a second slider is fixedly installed on both opposite sides of the extrusion frame.

[0016] Through the above technical solution, the second slider slides in the second groove, which can guide and limit the movement of the extrusion frame, ensure the stable movement of the extrusion frame, and ensure that the pull rope can accurately drive the pull rod.

[0017] As an improvement to the above technical solution, the outer surfaces of both the cylinder body and the lampshade are provided with a wear-resistant layer.

[0018] Through the above technical solutions, the wear-resistant layer can improve the wear resistance of the flashlight body and lampshade, reduce scratch damage during daily use, and extend the service life of the flashlight.

[0019] The beneficial effects of this utility model are:

[0020] This invention utilizes a linkage structure of spring, arc plate, and compression frame, combined with the threaded connection between the lamp holder and the high-intensity bulb, to form a dual fixing mode of "mechanical clamping + threaded fixing." During installation, no additional tools are required; simply press the compression frame to create installation space, and after releasing, the spring automatically drives the arc plate to tightly fit against the bulb surface. The threaded engagement effectively resists external impacts such as vibration and drops, solving the problem of inconsistent lighting caused by easy loosening in traditional single fixing methods. It is especially suitable for complex scenarios such as outdoor adventure and engineering operations, ensuring lighting stability. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0026] like Figure 1-3As shown, this utility model provides a technical solution: an installation structure for a high-intensity bulb in an aluminum alloy flashlight, including a body 1 and a lampshade 2 mounted on the body 1. Rubber anti-slip strips 13 are symmetrically installed on the outer surface of the body 1. These strips increase friction when the user holds the flashlight, preventing it from slipping and improving safety. Both the body 1 and the lampshade 2 are made of aluminum alloy, which is lightweight, high-strength, and has good thermal conductivity. This reduces the overall weight of the flashlight and facilitates heat dissipation from the high-intensity bulb 4, further improving heat dissipation. A wear-resistant layer 17, a ceramic coating, is provided on the outer surface of both the body 1 and the lampshade 2. This layer improves the wear resistance of the body 1 and the lampshade 2, reduces scratches during daily use, and extends the flashlight's lifespan.

[0027] Furthermore, a lamp holder 3 is provided inside the lamp cover 2, and a high-intensity bulb 4 is threadedly connected inside the lamp holder 3. A spring 5 is fixedly installed inside the lamp holder 3, and a moving block 6 is fixedly installed at one end of the spring 5. First sliders 14 are fixedly installed on both opposite sides of the moving block 6. A first groove adapted to the first slider 14 is opened inside the lamp holder 3. The first slider 14 slides in the first groove, which can guide the movement of the moving block 6, ensuring that the moving block 6 drives the pull rod 7 to move smoothly, so that the arc plate 9 clamps the high-intensity bulb 4 more stably.

[0028] Furthermore, a pull rod 7 is fixedly installed inside the movable block 6. A vertical plate 8 is fixedly installed at one end of the pull rod 7. One end of the vertical plate 8 extends through to the outside of the lamp holder 3 and is fixedly connected to an arc-shaped plate 9 that is compatible with the high-intensity bulb 4.

[0029] Furthermore, a concave cavity is formed on the outer surface of the lamp holder 3. A pressing frame 10 is slidably connected inside the concave cavity of the lamp holder 3. An anti-slip rubber pad 15 is fixedly installed on the outer side of the pressing frame 10. The anti-slip rubber pad 15 can increase the friction of the user's hand when pressing the pressing frame 10, making operation easier, and at the same time avoiding wear caused by direct contact between the hand and the pressing frame 10. A second slider 16 is fixedly installed on both opposite sides of the pressing frame 10. The second slider 16 slides in the second slide groove, which can guide and limit the movement of the pressing frame 10, ensuring the stable movement of the pressing frame 10 and ensuring that the pull rope 11 can accurately drive the pull rod 7 to move.

[0030] Furthermore, a pull rope 11 is fixedly installed on the inner wall of the compression frame 10, and a pulley 12 is rotatably connected to the inner wall of the recessed cavity opened inside the lamp holder 3. The pull rope 11 slides around the surface of the pulley 12, and the end of the pull rod 7 away from the vertical plate 8 passes through the interior of the recessed cavity and is connected to the pull rope 11.

[0031] The implementation principle of this utility model is as follows: When installing the high-intensity bulb 4, first press the squeezing frame 10. The squeezing frame 10 drives the second slider 16 to slide in the second slide groove. At the same time, the pull rope 11 and pulley 12 pull the pull rod 7. The pull rod 7 drives the moving block 6 to compress the spring 5. The first slider 14 slides synchronously along the first slide groove. The vertical plate 8 drives the arc plate 9 to move away from the center of the lamp holder 3 to form an installation space. After the high-intensity bulb 4 is screwed into the threaded hole of the lamp holder 3, the squeezing frame 10 is released. The spring 5 returns to its original position and pushes the moving block 6 and the pull rod 7 to move in the opposite direction. The arc plate 9 tightly fits the surface of the high-intensity bulb 4 to complete the fixation. When disassembling, press the squeezing frame 10 to separate the arc plate 9 from the bulb, and then unscrew the high-intensity bulb 4. The operation is simple and convenient. The arc plate 9 can clamp and fix the high-intensity bulb 4, reducing the possibility of the high-intensity bulb 4 becoming loose during use.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
