Detailed Implementation
[0016] 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.
[0017] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a telescopic multi-purpose flashlight includes a flashlight 1. The flashlight 1 consists of a handle 2, a lamp head 5, and a telescopic lampshade 6. The telescopic lampshade 6 is installed at the front end of the lamp head 5 through a limiting mechanism 21. A damping sleeve 19 is installed on the outer side of the front end of the lamp head 5, and the damping sleeve 19 contacts the inside of the telescopic lampshade 6. A controller 4 is installed on one side of the upper end of the handle 2. An environmental detector 9 is installed on the upper side of the controller 4. A power supply mechanism 11 is installed inside the handle 2. A compass 13 is installed at the end of the handle 2. A traction rope 7 is installed at the end of the handle 2. A display 10 is provided on the upper side of the controller 4. A control button 8 is installed on the upper side of the controller 4 next to the display 10. The controller 4 serves as the core of human-computer interaction. It receives user commands through the control button 8 and provides real-time feedback on the device status through the display 10. The display 10 can display internal parameters such as battery level and light intensity, as well as external data such as temperature and humidity collected by the environmental detector 9, realizing visualized operation and intuitive presentation of environmental information, thus improving user convenience.
[0018] The limiting mechanism 21 consists of a groove 22 and a protrusion 20. The protrusion 20 is installed inside the telescopic lampshade 6, and the groove 22 is located on the outside of the lamp head 5. The protrusion 20 is slidably installed inside the groove 22. The limiting mechanism 21 realizes the telescopic guidance of the lampshade through the "groove 22-protrusion 20" structure. The protrusion 20 inside the telescopic lampshade 6 is embedded in the groove 22 on the outside of the lamp head 5 to form a sliding pair. When an external force pushes the lampshade, the protrusion 20 slides linearly along the groove 22, restricting the lampshade to move only along the axis of the lamp head 5, avoiding rotation or offset, thereby ensuring the stability and accuracy of the telescopic process, and allowing the lampshade to adjust the illumination range as needed.
[0019] The power supply mechanism 11 consists of a battery 14 and a charging port 12. The battery 14 is installed inside the handle 2, and the charging port 12 is installed on one side of the handle 2. The power supply mechanism 11 adopts the "battery 14 energy storage + charging port 12 energy replenishment" mode. The battery 14 inside the handle 2 stores electrical energy and supplies power to components such as the lamp head 5, controller 4, and sensors through the circuit. When the charging port 12 is connected to an external power source, electrical energy flows into the battery 14 through the charging circuit to replenish the energy and ensure that the flashlight 1 can work continuously in the absence of an external power source, meeting the needs of outdoor or emergency scenarios.
[0020] The traction rope 7 has a spring wire 16 in the middle, and a steel wire mesh 17 is wrapped around the outside of the spring wire 16. The traction rope 7 achieves elastic cushioning and high-strength load through structural design. The spring wire 16 in the middle is elastic and can stretch when subjected to tension to relieve instantaneous impact force and prevent the traction rope 7 from breaking due to sudden force. The outer steel wire mesh 17 enhances wear resistance and tensile strength, improves overall strength, and allows the traction rope 7 to adapt to dynamic tension such as cushioning during climbing, as well as withstand static loads such as attaching equipment. A fixing bolt 18 is installed at one end of the traction rope 7. The traction rope 7 is rotatably installed inside the pre-drilled threaded hole on the upper side of the handle 2. The other end of the traction rope 7 is equipped with a hook 15. The traction rope 7 achieves flexible installation and multi-functional connection through a detachable structure. The fixing bolt 18 at one end is screwed into the pre-drilled hole of the handle 2 through a thread, and the user can install or remove it at any time as needed. The hook 15 at the other end can hook onto fixed points such as backpacks and tree branches. The elasticity of the spring wire 16 allows it to adapt to slight shaking when hanging. At the same time, the threaded connection of the fixing bolt 18 ensures that the traction rope 7 will not easily fall off during use, taking into account both convenience and reliability.
[0021] The environmental detector 9 is equipped with a temperature sensor and a humidity sensor. The environmental detector 9 collects environmental data through the sensors. The temperature sensor uses a thermistor to sense changes in ambient temperature and converts the thermal signal into an electrical signal. The humidity sensor senses humidity through changes in the physical properties of the hygroscopic material and also converts it into an electrical signal. After the two types of signals are processed by the controller 4, they are displayed on the display 10 or trigger preset functions to provide users with environmental reference.
[0022] The working principle and usage process of this utility model are as follows: The flashlight 1 integrates power supply and control functions through the handle 2, the lamp head 5 realizes the core function of lighting, and the telescopic lampshade 6 achieves adjustable illumination range through the cooperation of the limiting mechanism 21 and the damping sleeve 19. Specifically, the telescopic lampshade 6 restricts the range of motion of the telescopic lampshade 6 through the action of the limiting mechanism 21, and can extend and retract to change the beam focusing or diffusion state; the friction between the damping sleeve 19 and the inner wall of the lampshade makes it stably stay in any position; the controller 4 receives data from the environmental detector 9 and may adjust the lighting mode in conjunction with it, and can also connect to the ambient temperature and humidity in a timely manner, so that the user can make corresponding changes; the compass 13 allows the user to observe and use it in a timely manner; the power supply mechanism 11 provides power to the whole, the compass 13 is used for directional guidance, and the traction rope 7 is installed at the end of the handle 2 through the fixing bolt 18 for easy carrying or temporary fixation.
[0023] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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.
