[0021] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0022] The embodiment of the present application provides a special nozzle for fire extinguishers, which solves the problem that traditional nozzles are usually fixed directly on the fire-spraying end of the fire extinguisher. During use, the length of the nozzle is fixed. In many cases, some fire sources may have explosion hazards, so it is necessary to maintain a distance. If the traditional fire extinguisher maintains a distance, its accuracy will decrease, and the scattering range after the spray is large, and the distance is not far enough, thereby reducing the fire extinguishing effect. Moreover, if the distance is too close, it will also cause danger to personnel.

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] The utility model discloses a special nozzle for fire extinguisher. Figure 1-5 As shown, it includes a first nozzle seat 2 arranged on the fire extinguisher body 1 and an initial nozzle 201 arranged on the first nozzle seat 2. An extended nozzle 3 is provided on the initial nozzle 201. A quick docking mechanism 4 is provided between the extended nozzle 3 and the first nozzle seat 2. During use of the device, the extended nozzle 3 is added. When the extended nozzle 3 is not installed, the fire extinguisher is used in the same way as a traditional fire extinguisher. The fire-fighting liquid is sprayed from the initial nozzle 201. When encountering a fire hazard and needing to keep a distance, it is convenient to add the extended nozzle 3 so that the extended nozzle 3 is snapped into the initial nozzle 201, thereby increasing the fire extinguishing distance, making it easy to aim at the fire source location and increasing personnel safety.

[0025] A reinforcement rod 404 is fixedly connected to the extended nozzle 3, and a reinforcement tube 405 is fixedly connected to the first nozzle seat 2. The reinforcement rod 404 is movably clamped in the reinforcement tube 405. When the initial nozzle 201 and the extended nozzle 3 are docked, the device uses the reinforcement rod 404 and the reinforcement tube 405 to provide lateral support to the interface position, thereby ensuring stable docking of the initial nozzle 201 and the extended nozzle 3.

[0026] A storage mechanism 5 is provided on the fire extinguisher body 1, and the storage mechanism 5 is used to store the extended nozzle 3. The storage mechanism 5 includes a Velcro seat 501 and an adsorption Velcro 502 fixedly connected to the fire extinguisher body 1. The device provides limited storage for the extended nozzle 3 through the design of the storage mechanism 5. When storing, the extended nozzle 3 is placed between the Velcro seat 501 and the adsorption Velcro 502, and the Velcro seat 501 and the adsorption Velcro 502 are attached, so that the Velcro seat 501 and the adsorption Velcro 502 can clamp the extended nozzle 3.

[0027] The quick docking mechanism 4 includes an insert 401 provided on the extended nozzle 3 and a sleeve 402 provided on the first nozzle holder 2. The insert 401 is movably engaged in the sleeve 402. A clamping block 4033 is movably engaged in the sleeve 402. The insert 401 has a clamping slot 4011, and the clamping block 4033 is movably engaged in the clamping slot 4011.

[0028] The device facilitates the rapid docking of the extended nozzle 3 and the initial nozzle 201 through the design of the rapid docking mechanism 4. During docking, the insert 401 is directly engaged with the sleeve 402, and the clamping block 4033 is engaged with the clamping slot 4011.

[0029] An adjustment seat 403 is fixedly connected to the sleeve 402, and a screw rod 4031 is threadedly connected to the adjustment seat 403. An adjustment block 4032 is rotatably connected to the screw rod 4031. The adjustment block 4032 is slidably connected to the interior of the adjustment seat 403. The adjustment block 4032 is fixed to the clamping block 4033. A rotating handle 4034 is fixedly connected to the screw rod 4031. The design of the adjustment seat 403, the screw rod 4031 and the adjustment block 4032 makes it easy to move and adjust the clamping block 4033, thereby facilitating the installation, docking and locking of the initial nozzle 201 and the extended nozzle 3.

[0030] When controlling the movement of the card block 4033, it is only necessary to rotate the handle 4034. The rotating handle 4034 drives the screw rod 4031 to rotate, and the screw rod 4031 pushes the adjustment block 4032 and the card block 4033 to move. When the card block 4033 is engaged in the card slot 4011, the position of the insert block 401 and the sleeve 402 is locked.
