[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: like Figures 1 to 5 As shown, an embodiment of the present invention discloses a zoned, press-type, multi-agent combination fire extinguishing device, comprising a protective box 1, multiple fire extinguishers 3, and a trolley 2 in number equal to the number of fire extinguishers 3. The front surface of the protective box 1 has an interconnected opening 11 and a placement slot 12, wherein the opening 11 is located at the front of the protective box 1, and the placement slot 12 is located below the opening 11 and extends downward to the bottom plate of the protective box 1. The opening 11 is designed to be larger than the maximum outer diameter of the fire extinguishers 3 so that the trolley 2 can smoothly pass through the opening 11 and enter and exit the placement slot 12.

[0022] Multiple fire extinguishers 3 contain different extinguishing agents; for example, one fire extinguisher 3 contains dry powder extinguishing agent, another contains carbon dioxide extinguishing agent, and yet another contains water-based extinguishing agent, to deal with different types of fires. Each fire extinguisher 3 is detachably and fixedly mounted on an independent cart 2. Specifically, the cart 2 includes a base plate and a pull plate 21 vertically welded to the rear side of the base plate. The dimensions of the base plate of the cart 2 match the placement slot 12, allowing it to be inserted into the placement slot 12. The pull plate 21 is larger than the opening 11. When the cart 2 is fully inserted into the placement slot 12, the pull plate 21 precisely blocks the opening 11 from the front, while the base plate of the cart 2 blocks the lower part of the placement slot 12, thus creating a relatively sealed protective space inside the protective box 1. The advantage of this design is that it can effectively prevent external dust, oil stains and other impurities from entering the protective box 1, avoid the nozzle of the fire extinguisher 3 from being blocked by dust accumulation, and ensure that the fire extinguisher 3 can be used normally in an emergency.

[0023] To facilitate quick identification of the extinguishing medium type of each fire extinguisher 3 loaded on each cart 2, a label 211 is affixed to the front surface of the pull plate 21. The label 211 can clearly indicate information such as "dry powder fire extinguisher," "carbon dioxide fire extinguisher," and "water-based fire extinguisher" using text, colors, or icons. Additionally, the pull plate 21 is provided with a handle groove 212 for easy finger insertion and application of force.

[0024] Furthermore, this device includes a locking assembly that locks the trolley 2 inside the protective box 1 under normal conditions. The locking assembly includes a first fixing block 13, a locking rod 14, a spring 15, a locking cap 16, a handle 17, a second fixing block 18, and a third fixing block 22. The first fixing block 13 is welded to the top wall of the protective box 1. A through hole 131 is provided on the first fixing block 13, and the locking rod 14 slides through the through hole 131. A locking cap 16 is welded to the upper end of the locking rod 14, and the spring 15 is sleeved on the outer periphery of the locking rod 14. The spring 15 is fixedly connected to the locking cap 16, and the other end of the spring 15 is fixedly connected to the first fixing block 13.

[0025] The third fixing block 22 is welded to the pull plate 21, and its position corresponds to that of the first fixing block 13. The third fixing block 22 has a blind hole 221. When the trolley 2 is fully inserted into the placement slot 12 and the pull plate 21 is against the front side of the protective box 1, the blind hole 221 is exactly coaxially aligned with the through hole 131. Inserting the locking rod 14 into the blind hole 221 locks the relative position of the pull plate 21 and the protective box 1, thus locking the trolley 2.

[0026] Furthermore, a rotating block 161 is rotatably connected inside the lock cap 16, and the handle 17 is fixedly connected to the rotating block 161. A locking groove 181 is provided on the second fixing block 18. When a fire occurs and the fire extinguisher 3 needs to be retrieved, the user first pulls and rotates the handle 17 to make it engage with the locking groove 181. At this time, the locking component releases the lock on the pull plate 21. Then, the user grasps the handle groove 212 on the corresponding pull plate 21 and pulls the pull plate 21 outward to smoothly pull the cart 2 along with the fire extinguisher 3 from the protective box 1. Subsequently, the user can push the cart 2 to quickly move to the fire source. Since the bottom of the cart 2 is usually equipped with casters, even operators with weaker physical strength can easily and quickly move the fire extinguisher 3, thereby promptly carrying out firefighting operations. After the fire extinguisher 3 is used up, push the trolley 2 back into the placement slot 12, press down the lock cap 16 to insert the locking rod 14 into the insertion hole 221, and turn the handle 17 into the locking slot 181 to restore the locked state.

[0027] Example 2: like Figure 1 , Figure 6 and Figure 7As shown, a pair of bevels 201 are provided on the front edge of the base plate of the trolley 2. The two bevels 201 are located on the left and right sides of the base plate of the trolley 2, respectively, so that the front end of the trolley 2 forms a trapezoidal or triangular guide structure. Correspondingly, a pair of blocking blocks 121 that match the bevels 201 are fixedly connected to the wall of the placement slot 12. When the trolley 2 is inserted into the placement slot 12, the bevels 201 can guide the trolley 2 to smoothly enter the placement slot 12. After the trolley 2 is fully inserted, the bevels 201 and the blocking blocks 121 form a surface contact fit, and the two together seal the base plate of the protective box 1, further improving the sealing of the bottom of the protective box 1 and preventing dust from entering from the gaps in the base plate.

[0028] Furthermore, a mounting bracket 213 is fixedly installed on the upper surface of the base plate of the trolley 2. The mounting bracket 213 has a circular groove for placing the bottom of the fire extinguisher 3. A clamp 214 is installed on the side of the pull plate 21 facing the inside of the protective box 1. The clamp 214 is used to secure the upper part of the fire extinguisher 3. Through the cooperation of the mounting bracket 213 and the clamp 214, the fire extinguisher 3 is firmly fixed to the trolley 2. Even if the trolley 2 bumps or tilts during movement, the fire extinguisher 3 will not fall off or shake, ensuring the safety of the transportation process.

[0029] Furthermore, in this embodiment, the number of openings 11 and placement slots 12 is set to three, corresponding to three trolleys 2 containing different extinguishing media. In practical applications, two, four, or more can be set as needed to meet the fire protection configuration requirements of different locations. Each trolley 2 has a corresponding label 211 affixed to its pull plate 21, and the handle slot 212 and locking component on each pull plate 21 are independent. Users can select and pull out the corresponding trolley 2 according to the type of fire source, realizing zoned and on-demand access.

[0030] A method for using a zoned, press-type, multi-agent combined fire extinguishing device includes the following steps: S1. Unlocking step: Rotate and pull handle 17 to disengage locking rod 14 from the insertion hole 221 of third fixing block 22, thereby releasing the lock between trolley 2 and protective box 1. S2. Retrieval Step: Hold the handle slot 212 of the pull plate 21 and pull the trolley 2 carrying the fire extinguisher 3 out of the placement slot 12 of the protective box 1. S3. Mobile firefighting procedure: Push the trolley 2 carrying the fire extinguisher 3 to the fire scene to carry out firefighting; S4. Reset step: After extinguishing the fire, push the trolley 2 into the placement slot 12, press the lock cap 16 to insert the lock rod 14 into the insertion hole 221, rotate the handle 17 to lock into the locking slot 181, so as to lock and seal the trolley 2 and the protective box 1.
