Description

Technical Field

[0001] This utility model relates to the field of fire suppression equipment technology, and in particular to a portable fire suppression device. Background Technology

[0002] Forest fire-fighting mops are powerful tools in forest fire suppression. Compared to other firefighting tools, fire-fighting mops have advantages such as simple operation, low cost, and significant effectiveness in extinguishing small fires. They are one of the essential pieces of equipment for forest fire brigades and forest rangers in dealing with initial forest fires, contributing significantly to protecting forest safety. It mainly consists of a long pole and a fire-striking whip. The long pole is generally made of high-strength and lightweight materials, ensuring that the user can easily grip and operate it from a distance, reducing the danger of close contact with the fire source. The fire-striking whip is made of special flame-retardant fiber material, which not only effectively withstands the high temperature of flames but also has good adsorption and striking ability. When extinguishing a fire, by waving the fire-fighting mop, the fire-striking whip can quickly cover the flames, achieving the purpose of extinguishing the fire by isolating oxygen or striking the flames.

[0003] However, the fire-fighting mop's fire whip is easily damaged during firefighting. The one-piece fire-fighting mop can only be replaced as a whole after it is damaged, causing unnecessary losses. At the same time, the fire-fighting mop is relatively long, which is not conducive to storage and transportation. Therefore, it is necessary to improve it. Utility Model Content

[0027] To enable quick replacement of worn fire starter 1, and to facilitate the storage and transportation of fire-fighting mops, this utility model provides a portable fire-fighting device, such as... Figures 1-5 As shown, the device includes a fire whip 1 and a handle 2. A quick connector 3 is located at the top of the fire whip 1, and a connector locking component 4 is fitted to one end of the handle 2. This design allows the fire whip 1 to be quickly plugged in or disassembled, facilitating replacement and maintenance during use. It avoids the need for complete replacement required by traditional integrated structures, thus reducing unnecessary resource waste. The connection method between the fire whip 1 and the handle 2 simplifies operation; users can easily disassemble or install the fire whip 1 without the need for complex tools, improving operational efficiency and ease of use. The connector locking component 4 ensures a secure connection of the fire whip 1 during use, preventing loosening or detachment and enhancing safety. This design allows users to quickly replace damaged fire whip 1 as needed, extending the overall lifespan of the device. Furthermore, this portable fire suppression device has a more compact structure; the fire whip 1 can be disassembled separately when not in use, facilitating storage and transportation, saving space and enabling rapid response by forest fire brigades. The overall design emphasizes portability, ease of operation, and replaceability, overcoming the shortcomings of traditional firefighting equipment that is difficult to maintain and store, and providing a more efficient and economical solution for forest fire fighting.

[0028] In a preferred embodiment, the fire whip 1 includes multiple whip strips 11, which are evenly arranged circumferentially at one end of the whip head 12 and securely fixed to the whip head 12 by a retaining ring 13, ensuring that the whip strips 11 will not loosen or shift during use. A quick connector 3 fixed to the other end of the whip head 12 allows the fire whip 1 to be easily connected to or disconnected from the handle 2, improving the device's convenience and flexibility. Because the whip strips 11 of the fire whip 1 are evenly distributed on the whip head 12, the overall coverage area and striking power are effectively enhanced, enabling it to quickly cover flames and isolate oxygen during fire suppression, thereby improving the fire extinguishing effect. The design of multiple whip strips 11 allows each swing to generate a greater striking force, enhancing the ability to extinguish initial fires and improving the device's adaptability to different fire sources and intensities. The quick connector 3 not only enables convenient connection to the handle 2 but also allows for quick disassembly after use, facilitating storage and transportation.

[0029] In a preferred embodiment, to improve the adaptability of the grip 2, one end of the grip 2 is equipped with a quick connector 3 identical to that on the fire starter 1. This connector connects to the connector locking component 4 of another grip 2, thereby increasing the length of the grip 2 and ensuring a longer safe distance for firefighters in special circumstances. Through the quick connector 3, users can easily extend or shorten the length of the grip 2 according to actual needs, adapting to different fire source extinguishing requirements or changes in the operating environment. This design also makes carrying and storing the grip 2 more convenient; multiple detachable grip 2 parts save storage space and facilitate transportation.

[0030] In a preferred embodiment, the connector locking component 4 includes a locking cylinder 41, locking balls 42, a spring 43, a locking sleeve 45, and a connecting cylinder 44. The locking cylinder 41 is a hollow cylinder with four circumferentially evenly arranged circular mounting holes 46 on its upper part. The diameter of the opening of the mounting holes 46 inside the locking cylinder 41 is larger than the diameter of the opening on the outside of the locking cylinder 41. The locking balls 42 are spherical and there are four of them, which are installed in each mounting hole 46. The connecting cylinder 44 is located at the lower part of the locking cylinder 41 and is used to connect with the handle 2 to ensure that the connector locking component 4 can be firmly fixed to the handle 2, providing more robust support.

[0031] Spring 43 is sleeved on locking cylinder 41 and fixed at one end to connecting cylinder 44. Lock sleeve 45 is sleeved on spring 43 and connected to the other end of spring 43. The outer diameter of locking cylinder 41 is smaller than that of connecting cylinder 44, the outer diameter of spring 43 is larger than that of locking cylinder 41 but smaller than that of connecting cylinder 44, and the inner diameter of lock sleeve 45 is larger than that of connecting cylinder 44. A limiting ring 451 is provided at the top of lock sleeve 45, connected to spring 43, and the inner diameter of limiting ring 451 is larger than that of locking cylinder 41. Quick connector 3 includes plug 31 and locking groove 32. Locking groove 32 is circumferentially disposed on plug 31. Plug 31 is inserted into locking cylinder 41. Lock sleeve 45 pushes locking ball 42 into locking groove 32 to lock quick connector 3. When the connector locking component 4 is not in use, the locking sleeve 45 is flush with the locking cylinder 41 under the elastic force of the spring 43, and the locking ball 42 is pushed into the locking cylinder 41 by the locking sleeve 45 to seal the opening of the locking cylinder 41. When in use, the locking sleeve 45 is moved away from the end of the lighter 1, and the locking ball 42 falls naturally due to gravity, opening the opening of the locking cylinder 41. The plug 31 is then inserted into the locking cylinder 41, and then the locking sleeve 45 is put back. Due to the push of the elastic force of the spring 43, the locking sleeve 45 returns to its initial state, pushing the locking ball 42 into the locking cylinder 41. The locking ball 42 pushed into the locking cylinder 41 slides into the locking groove 32 to lock the lighter 1.

[0032] In a preferred embodiment, the quick connector 3 further optimizes the connection structure to enhance the stability of the fire whip 1 and the handle 2. The quick connector 3 includes locking holes 33, the number of which is the same as the locking balls 42 and are evenly distributed circumferentially within the locking grooves 32. With this design, the locking balls 42 roll into the locking holes 33 only after the plug 31 is inserted into the locking cylinder 41, allowing the locking sleeve 45 to push upwards further to lock the quick connector 3, thereby restricting the circumferential rotation of the fire whip 1. This structure effectively prevents unnecessary rotation or loosening of the fire whip 1 during firefighting due to swinging or external forces.

[0033] In a preferred embodiment, the connecting cylinder 44 has an internal thread 47, and the end of the handle 2 that connects to the connector locking component 4 has an external thread 21. This threaded connection ensures a tight fit between the handle 2 and the connector locking component 4, guaranteeing a stable and reliable connection. The user can easily rotate the handle 2 to securely connect it to the connector locking component 4.

[0034] In a preferred embodiment, the outer surface of the lock sleeve 45 is provided with annularly distributed anti-slip textures 452, a design that significantly improves stability and safety when gripping. The annular anti-slip textures 452, through their evenly distributed structure, effectively increase the contact friction with the hand, reducing the risk of hand slippage in wet or high-temperature conditions, and ensuring that the user can firmly grip the lock sleeve 45 during operation.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
