A portable underwater flash

Abstract

This utility model relates to the field of underwater photography and discloses a portable underwater flash, including a lamp housing with a groove inside. Multiple inner soft pads are fixedly connected to the outer periphery of the lamp housing, and spring rods are fixedly connected to the outer sides of each inner soft pad. An outer soft pad is fixedly connected to the other end of each spring rod, and a shock-resistant outer shell is fixedly connected to the outer soft pad. Waterproof rubber rings are fixedly connected to the upper and lower ends of the shock-resistant outer shell, and these waterproof rubber rings are all fitted around the outer periphery of the lamp housing. In this utility model, when the main body is subjected to an accidental collision, the shock-resistant outer shell will be compressed, transmitting the force to the spring rods. The spring rods are compressed and reset with the lamp housing as the fulcrum, buffering the force. The waterproof rubber rings prevent water from entering the protective shell and causing internal components to rust. This effectively resists damage to the optical components of the flash head from underwater collisions and scratches, while not obstructing the illumination area, compressing the watertightness of the flash body, or compromising its portability, ensuring stable use of the flash in underwater operations.

Description

Technical Field

[0001] This utility model relates to the field of underwater photography, and in particular to a portable underwater flash. Background Technology

[0002] In underwater photography, exploration, search and rescue operations, natural light decreases sharply with increasing water depth, resulting in a dark environment that affects the operation and shooting results. Underwater flashes have thus become a key lighting device. Although such products on the market can meet basic needs, they have obvious shortcomings in portability and cable water tightness. For example, some devices are bulky and difficult to operate due to their heavy protective structure. Cables and interfaces are prone to sealing failure and water leakage when immersed for a long time or when exposed to changes in water pressure. They are difficult to flexibly adapt to diverse underwater operation scenarios.

[0003] Currently used traditional portable underwater flashlights are mostly composed of simple components such as LED lights and light housings, which can only meet simple and single underwater operation needs.

[0004] Existing underwater flashlights often lack specific protective structures against underwater collisions and scratches. During underwater operations, these flashlights are susceptible to collisions or scratches from rocks and other underwater objects, which can damage the optical components of the flashlight head and affect the lighting effect. They are also bulky, heavy, and poorly portable, increasing the burden on users and limiting their application range when working underwater for extended periods or carrying multiple devices. Furthermore, the watertight devices for cables are often complex and prone to deterioration in watertightness after prolonged use, leading to water seepage, short circuits, and equipment damage. This not only affects normal use and lifespan but may also threaten user safety. Therefore, a portable underwater flashlight is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a portable underwater flash light, which aims to improve the problems of lack of protective structure and insufficient water tightness in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A portable underwater flashlight includes a lamp housing with a groove inside. Multiple inner soft pads are fixedly connected to the outer periphery of the lamp housing. Spring rods are fixedly connected to the outer sides of each inner soft pad. An outer soft pad is fixedly connected to the other end of each spring rod. An anti-collision shell is fixedly connected to the outer soft pad. Waterproof rubber rings are fixedly connected to the upper and lower ends of the anti-collision shell, and the waterproof rubber rings are all fitted around the outer periphery of the lamp housing.

[0008] As a further description of the above technical solution:

[0009] The lamp housing is provided with a cable sealing device at the bottom, and the cable sealing device is provided with threads inside. The lamp housing is made of lightweight and high-strength material.

[0015] A lamp holder is installed in the groove of the lamp housing, and multiple LED bulbs are fixedly connected to the top of the lamp holder;

[0016] As a further description of the above technical solution:

[0017] A spring-loaded input cable is fixedly connected to the bottom of the lamp stand, and a receiver is fixedly connected to the other end of the spring-loaded input cable. The receiver is fixedly connected to the inside of the cable sealing device.

[0021] A buoyancy base is fixedly connected to the outer side of the flash housing, and a buoyancy ball is fixedly connected to the buoyancy base.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the multi-layer protective structure composed of inner soft pad, spring rod, outer soft pad and anti-collision shell ensures that when the flash lamp encounters underwater reefs, objects, collision or scratches, the anti-collision shell is subjected to force first, and then the spring rod is compressed and reset to buffer the impact force. The inner and outer soft pads further absorb the vibration, which can effectively resist the damage of external force to the lamp shell and internal lamp head optical components, and avoid affecting the supplementary lighting effect.

[0024] 2. In this utility model, the cable sealing device with threads at the bottom of the lamp housing can tightly seal the connection between the cable and the lamp body, preventing underwater water from seeping in, avoiding short circuits and component damage caused by seal failure and water seepage, extending the life of the equipment and reducing safety risks. Moreover, the lamp housing is made of lightweight and high-strength materials, which not only meets the portability requirements of small size and light weight, reducing the burden on users' work and carrying, and expanding the application scenarios, but also enhances the lamp housing's resistance to external forces with high strength, helping to improve the overall durability of the equipment and reduce daily damage.

Detailed Implementation

[0031] 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 protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2This utility model provides an embodiment of a portable underwater flash, comprising a lamp housing 1. The lamp housing 1 is the basic frame component of the entire flash, mainly used to support and protect the core optical components such as the internal lamp holder 11 and LED bulb 12, while providing installation support for the outer protective structure such as the inner soft pads 2. The lamp housing 1 has a groove inside, which provides a precise installation space for the lamp holder 11, ensuring that the lamp holder 11 and the LED bulb 12 above it can be stably fixed, avoiding the impact of shaking on the lighting angle and supplementary lighting effect during underwater operations. Multiple inner soft pads 2 are fixedly connected to the outer periphery of the lamp housing 1. The inner soft pads 2 are made of elastic material, which can buffer the impact force between the lamp housing 1 and the spring rod 3, reducing direct wear during collision, and can fill the gap between the two, improving the stability of the overall structure. Spring rods 3 are fixedly connected to the outer side of each inner soft pad 2. The spring rods 3 are core buffer components. When the anti-collision shell 5 is subjected to external force, the spring rods 3 can absorb the force through compression deformation. Most of the impact force is released through a reset action, thus preventing external force from being directly transmitted to the inside of the lamp housing 1. The other end of the spring rod 3 is fixedly connected to an outer soft pad 4. The outer soft pad 4 has a similar function to the inner soft pad 2, mainly used to buffer the force between the spring rod 3 and the anti-collision shell 5, while protecting the end of the spring rod 3 from friction damage from the anti-collision shell 5. The outer soft pad 4 is fixedly connected to the anti-collision shell 5. As the outermost protective structure, the anti-collision shell 5 is made of wear-resistant and impact-resistant material, which can directly resist the collision and scratching of underwater reefs and objects, providing the first protective barrier for the internal components. The upper and lower ends of the anti-collision shell 5 are fixedly connected to waterproof rubber rings 6. The waterproof rubber rings 6 have good sealing and elasticity, which can fill the gap between the anti-collision shell 5 and the lamp housing 1, preventing underwater water from seeping into the interior from the connection point. The waterproof rubber rings 6 are all fitted around the outer periphery of the lamp housing 1. This fitting method allows the waterproof rubber rings 6 to fit tightly with the lamp housing 1, further improving the sealing effect, and at the same time facilitating the installation and removal of the anti-collision shell 5.

[0033] Reference Figure 1 and Figure 3 The bottom of the lamp housing 1 is equipped with a cable sealing device 7, which is a key component to ensure the water tightness of the equipment. It is mainly used to seal the connection between the spring input cable 18 and the lamp housing 1, preventing water from seeping into the internal circuit through the cable gaps. The cable sealing device 7 has internal threads that match the bolt power supply head 15 on the top of the waterproof power supply 14. The threaded connection can achieve a tight fixation between the cable sealing device 7 and the waterproof power supply 14, while enhancing the sealing of the connection between the two and preventing water leakage. The lamp housing 1 is made of lightweight and high-strength materials. The lightweight materials can effectively reduce the overall weight of the lamp housing 1, improve the portability of the equipment, and reduce the burden on users when working underwater. The high-strength materials can enhance the lamp housing 1's resistance to external forces, prevent the lamp housing 1 from deforming when it is hit or squeezed, and protect the internal components.

[0034] reference Figure 1-4A flash lamp housing 8 is fixedly connected to the bottom of the lamp housing 1. The flash lamp housing 8 surrounds the outside of the bottom of the lamp housing 1, protecting components such as the cable sealing device 7 and the spring input cable 18 at the bottom of the lamp housing 1, and providing a mounting carrier for the power switch 9, the power display screen 10, and the buoyancy base 16. The flash lamp housing 8 is fixedly connected to the top of the cable sealing device 7. This connection method forms an integral structure with the lamp housing 1 and the flash lamp housing 8, improving the stability of the equipment and preventing the cable sealing device 7 from falling off due to independent force. The power switch 9 is slidably connected to the outer periphery of the flash lamp housing 8. The power switch 9 is the operating component that controls the start and stop of the equipment. The user can turn the LED bulb 12 on and off by sliding the power switch 9. The closed, sliding connection method allows for convenient operation and precise control in underwater environments. A power display screen 10 is fixedly connected to the outer periphery of the flashlight housing 8. The power display screen 10 shows the remaining power of the waterproof power supply 14 in real time, allowing users to easily understand the power supply status of the equipment and preventing sudden shutdown due to insufficient power during underwater operations, thus affecting the work progress. A lamp holder 11 is installed in the groove of the lamp housing 1. The lamp holder 11 serves as the mounting base for the LED bulbs 12, providing a stable mounting position for multiple LED bulbs 12 and ensuring their neat arrangement. Simultaneously, the lamp holder 11 has good thermal conductivity, dissipating the heat generated by the LED bulbs 12 during operation and preventing heat buildup that could affect the lifespan of the LED bulbs 12. Multiple LED bulbs 12 are fixedly connected to the top of the light stand 11. These LED bulbs 12 are the core lighting components of the equipment, featuring high brightness, low energy consumption, and long lifespan. The combined operation of multiple LED bulbs 12 provides ample illumination, meeting the supplementary lighting needs of underwater photography, exploration, and search and rescue scenarios, enhancing the brightness of the work area, and improving shooting and operational effects. A spring-loaded input cable 18 is fixedly connected to the bottom of the light stand 11. This cable 18 is a key component for power transmission; one end connects to the light stand 11, and the other end connects to the receiver 13. It stably transmits the power provided by the waterproof power supply 14 to the light stand 11 to power the LED bulbs 12. The spring-loaded design ensures the cable remains stable even when the equipment is slightly shaken or subjected to force, preventing damage due to pulling. The other end of the spring input cable 18 is fixedly connected to a receiver 13. The receiver 13 is a power transmission adapter that connects the spring input cable 18 to the circuit inside the cable sealing device 7, ensuring smooth power transmission. The receiver 13 also has a certain degree of sealing to prevent moisture from seeping into the cable through the cable connector. The receiver 13 is fixedly connected to the inside of the cable sealing device 7, ensuring a stable connection and preventing it from loosening due to shaking during underwater operation, which would affect power transmission. A waterproof power supply 14 is located at the bottom of the cable sealing device 7. The waterproof power supply 14 is the core power supply of the equipment; its waterproof design ensures normal operation in the underwater environment and prevents short circuits due to moisture infiltration.To continuously provide stable power to components such as LED bulbs 12, ensuring the normal operation of the equipment;

[0035] A bolt power supply head 15 is fixedly connected to the top of the waterproof power supply 14. The bolt power supply head 15 serves two purposes: firstly, it is a power output component, transmitting power from the waterproof power supply 14 to the internal circuitry of the cable sealing device 7; secondly, its external threads match the internal threads of the cable sealing device 7, achieving a tight fixation between the waterproof power supply 14 and the cable sealing device 7 through this threaded connection, while also enhancing the sealing performance of the connection. The bolt power supply head 15 is threaded inside the cable sealing device 7. This connection method not only facilitates installation and disassembly, making it convenient for future replacement or maintenance of the waterproof power supply 14, but also further prevents moisture from seeping in through the connection point through the tight engagement of the threads, improving the overall performance of the equipment. The flash housing 8 is watertight, and a buoyancy base 16 is fixedly connected to the outside of the flash housing 8. The buoyancy base 16 is the mounting base for the buoyancy ball 17, which can stably fix the buoyancy ball 17 to the outside of the flash housing 8. At the same time, the buoyancy base 16 itself also has a certain buoyancy, which can help improve the overall buoyancy of the device. The buoyancy ball 17 is fixedly connected to the buoyancy base 16. The buoyancy ball 17 is made of lightweight, high-buoyancy material. Its main function is to provide upward buoyancy for the device, offset part of the weight of the device, so that the device has better buoyancy performance underwater, preventing the device from sinking quickly due to excessive weight, making it convenient for users to operate the device underwater. At the same time, it can also prevent the device from sinking to the bottom quickly when it is accidentally dropped, making it easy to recover.

[0036] Working principle: When the device is in use, the waterproof power supply 14 provides power, and its top bolt power supply head 15 cooperates with the cable sealing device 7 to form a sealed power supply channel. The user operates the power switch 9 on the flash housing 8 to turn on the circuit. The power is transmitted through the receiver head 13 and the spring input wire 18 in the cable sealing device 7 to the lamp holder 11 in the groove of the lamp housing 1, which powers the LED bulb 12 on the top of the lamp holder 11 to provide supplementary lighting. At the same time, the power display screen 10 displays the remaining power of the waterproof power supply 14 in real time.

[0037] When encountering collisions or scratches underwater, the outer anti-collision shell 5 first bears the external force. The impact force is initially buffered by the outer soft pad 4 and then transmitted to the spring rod 3. The spring rod 3 is compressed and reset with the inner soft pad 2 on the outer periphery of the lamp housing 1 as the fulcrum, further dissipating the impact force. The inner soft pad 2 then absorbs the residual vibration, protecting the lamp housing 1 and the internal optical components.

[0038] In terms of sealing, the waterproof rubber rings 6 at the top and bottom of the anti-collision shell 5 fit tightly with the lamp shell 1, and together with the cable sealing device 7, they prevent water from seeping in; the outer side of the flash lamp shell 8 provides buoyancy through the buoyancy ball 17 connected to the buoyancy seat 16, which helps the equipment to remain stable underwater and meet the needs of underwater operations.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
