Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing devices, specifically a novel carbon dioxide fire extinguishing device for fire fighting. Background Technology

[0002] Carbon dioxide fire extinguishing primarily works by reducing oxygen concentration and cooling. Under pressure, carbon dioxide is stored in a liquid form in a container. When released, it rapidly vaporizes, filling the protected area and reducing the oxygen content to a level insufficient to support combustion. Simultaneously, it absorbs heat and lowers the temperature, thereby extinguishing the fire.

[0003] In existing technologies, when a fire breaks out in a certain area and carbon dioxide fire extinguishing devices are used for firefighting, there are often serious challenges due to the limited length of the fire extinguisher hose and nozzle. When the fire is fierce, firefighters are threatened by high temperature, thick smoke and flames, making it difficult to get close to the fire source. As a result, the short hose and nozzle cannot accurately spray carbon dioxide to the core area of ​​the fire and cannot effectively cover the fire source, thus resulting in low fire extinguishing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a novel carbon dioxide fire extinguishing device for fire fighting, in order to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A novel carbon dioxide fire extinguishing device for fire fighting includes a fire extinguisher body. An opening and closing valve assembly is fixedly installed on the upper end of the fire extinguisher body. A flexible hose is fixedly sleeved inside one side of the opening and closing valve assembly. A handle bracket is fixedly installed at one end of the flexible hose. A fixing component for easy disassembly and installation of an extension handle is provided at one end of the fixing component. An adjustment component for telescopic adjustment of the handle is provided at one end of the adjustment component. A nozzle sleeve is fixedly installed at one end of the adjustment component.

Detailed Implementation

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Figure 1 As shown, a novel carbon dioxide fire extinguishing device for fire fighting includes a fire extinguisher body 1. An opening and closing valve assembly 2 is fixedly installed on the upper end of the fire extinguisher body 1. A hose 3 is fixedly sleeved inside one side of the opening and closing valve assembly 2. A handle bracket 4 is fixedly installed at one end of the hose 3. A fixing component 5 for easy disassembly and installation of an extension handle bracket is provided at one end of the handle bracket. An adjustment component 6 for telescopic adjustment of the handle bracket is provided at one end of the adjustment component 6. A nozzle sleeve 7 is fixedly installed at one end of the adjustment component 6.

[0024] In a specific embodiment, when a fire occurs, the firefighters first need to activate the core process of the device: by operating the opening and closing valve assembly 2, the fire extinguisher body 1 is opened, allowing the carbon dioxide gas stored inside to be released. The gas is transmitted through the hose 3 to the front spray assembly handle bracket 4, fixing assembly 5, adjusting assembly 6 and nozzle sleeve 7, and finally sprayed out by the nozzle sleeve 7 to extinguish the fire. When it is necessary to extend the spray distance, an extension handle bracket can be installed through the fixing assembly 5 to additionally configure an extension rod. Assembly can be completed without tools. The firefighters adjust the length of the adjusting assembly 6 according to the distance to the fire source. When the fire is fierce, the handle bracket is extended to move the nozzle sleeve 7 away from the firefighters and spray from a safe distance. When the fire is small, the length is shortened to accurately aim at the core of the fire source.

[0025] Please refer to Figures 1 to 3As shown, as a technical optimization of this utility model, the fixing component 5 includes a sleeve 51. A handle bracket 4 is fitted on the inner wall of one end of the sleeve 51. A connecting block 52 is fixedly connected to the outer side of one end of the sleeve 51. A sleeve groove 59 is opened inside one end of the sleeve 51. A sealing plate 510 is provided inside the sleeve groove 59. The sealing plate 510 is in close contact with the surface of one end of the handle bracket 4. A telescopic cylinder 53 is fixedly installed on the outer side of one end of the connecting block 52. A compression spring 57 is fixedly installed on the inner wall of the telescopic cylinder 53. A movable piece 56 is fixedly connected to one end of the compression spring 57. A pin rod 55 is fixedly connected inside the movable piece 56. A handle 58 is fixedly connected to one end of the pin rod 55. The pin rod 55 slides through the inner side of one end of the sleeve 51 and is engaged inside the handle bracket 4. A pin hole 54 is opened inside the outer side of one end of the handle bracket 4.

[0026] In a specific embodiment, when it is necessary to extend the hose 3 of the fire extinguisher, the handle bracket 4 is fitted onto the inner wall of one end of the sleeve 51, so that the sealing plate 510 is in close contact with the surface of one end of the handle bracket 4, ensuring the stability of the installation and a certain degree of sealing. At this time, the pin rod 55 is not engaged with the pin hole 54 on the handle bracket 4, and the handle bracket 4 can be adjusted by rotating it appropriately relative to the sleeve 51. When it is necessary to fix the handle bracket 4, the handle 58 is manually pulled, which drives the pin rod 55 to slide along the inside of one end of the sleeve 51, so that it is aligned with the pin hole 54 on the handle bracket 4. Then the handle 58 is released, and under the elastic action of the compression spring 57, the movable piece 56 pushes the pin rod 55 to move towards the handle bracket 4 until the pin rod 55 is fully engaged in the pin hole 54, thereby fixing the handle bracket 4.

[0027] Please refer to Figures 1 to 4 As shown, as a technical optimization of this utility model, the adjusting component 6 includes a first steel pipe 61, one end of which is fixedly connected to a flange 65. One end of each flange 65 is bolted to the inside of a connecting block 52. Sliding rods 63 are slidably connected to the inner wall of the first steel pipe 61. A second steel pipe 62 is fixedly connected to one side of each of the sliding rods 63. A fixing block 64 is fixedly connected to the outer side of one end of the second steel pipe 62. A bushing 66 is fixedly sleeved inside one end of the fixing block 64. A lead screw 67 is rotatably connected inside the bushing 66. The outer side of the lead screw 67 is rotatably connected to the inside of a support block 68 near the center. One end of the support block 68 is fixedly connected to the outer side of the first steel pipe 61 near one end. A second steel pipe 62 is fixedly installed at one end of the second steel pipe 62.

[0028] In a specific embodiment, the adjusting component 6 is in its initial installation state. The first steel pipe 61 is fixed to the connecting block 52 via the flange 65. The second steel pipe 62 and the sliding rod 63 are located inside the first steel pipe 61. The operator rotates the lead screw 67, and the rotational movement of the lead screw 67 is transmitted to the second steel pipe 62 through the bushing 66 and the fixing block 64. When the lead screw 67 rotates, due to the rotational connection between the lead screw 67 and the bushing 66, and the fixed connection between the bushing 66 and the fixing block 64, the fixing block 64 and the second steel pipe 62 on it will be driven to produce The second steel pipe 62 moves linearly under the drive of the lead screw 67. Since the second steel pipe 62 is fixedly connected to the sliding rod 63, the sliding rod 63 will also slide inside the first steel pipe 61, which can realize the extension or retraction of the second steel pipe 62 relative to the first steel pipe 61. The firefighters adjust the length of the adjusting component 6 according to the distance of the fire source. When the fire is fierce, the first steel pipe 61 is extended so that the nozzle sleeve 7 is away from itself and sprays from a safe distance. When the fire is small, the length of the first steel pipe 61 is shortened to accurately aim at the core of the fire source.

[0029] When using this utility model, if it is necessary to extend the hose 3 of the fire extinguisher, the handle bracket 4 is fitted onto the inner wall of one end of the sleeve 51, so that the sealing plate 510 is in close contact with the surface of one end of the handle bracket 4, ensuring the stability of the installation and a certain degree of sealing. At this time, the pin 55 is not engaged with the pin hole 54 on the handle bracket 4. The handle bracket 4 can be adjusted by rotating it relative to the sleeve 51. When it is necessary to fix the handle bracket 4, manually pull the handle 58 to slide the pin 55 along the inside of one end of the sleeve 51, aligning it with the pin hole 54 on the handle bracket 4. Then release the handle 58. Under the elastic action of the compression spring 57, the movable piece 56 pushes the pin 55 towards the handle bracket 4 until the pin 55 is fully engaged in the pin hole 54, thus fixing the handle bracket 4. The adjusting component 6 is in the initial installation state. The first steel pipe 61 is fixed to the connecting block 52 by the flange 65. The second steel pipe 62 and the sliding rod 63 are located inside the first steel pipe 61. The operator rotates the screw 67. The rotation of the screw 67... The motion is transmitted to the second steel pipe 62 through the bushing 66 and the fixed block 64. When the lead screw 67 rotates, due to the rotational connection between the lead screw 67 and the bushing 66, and the fixed connection between the bushing 66 and the fixed block 64, the fixed block 64 and the second steel pipe 62 on it will generate linear motion. The second steel pipe 62 generates linear motion under the drive of the lead screw 67. Since the second steel pipe 62 is fixedly connected to the sliding rod 63, the sliding rod 63 will also slide inside the first steel pipe 61, which can realize the extension or retraction of the second steel pipe 62 relative to the first steel pipe 61. The firefighters adjust the length of the adjusting component 6 according to the distance of the fire source. When the fire is fierce, the first steel pipe 61 is extended so that the nozzle sleeve 7 is away from itself and sprays from a safe distance. When the fire is small, the length of the first steel pipe 61 is shortened to accurately aim at the core of the fire source.
