Abstract

This utility model discloses a telescopic foam hook fire extinguisher, relating to the field of fire extinguishing equipment technology. It includes a main body, a bracket mounted on the side of the main body, and a connector mounted on the bottom of the main body. The multi-section telescopic tube can be stretched or retracted according to the distance requirements of the fire extinguishing scenario, facilitating adjustment of the distance between the nozzle and the fire source, thus enabling precise spraying of distant or hard-to-reach fire sources. Furthermore, a hinge rod enables the hinge block to rotate and connect with the telescopic tube, facilitating spraying of fire sources in special locations such as inclined surfaces and corners, improving the comprehensiveness and accuracy of fire extinguishing, and enabling multi-angle, no-dead-angle fire extinguishing. The limiting teeth tightly engage with the limiting groove of the hinge block, facilitating quick locking of the nozzle angle, improving operational stability and efficiency, and enabling the rapid fixing of the optimal spray angle based on the fire source location. Ultimately, this solves the problems of limited operating range and inconvenient angle adjustment in existing devices.

Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing equipment technology, and in particular to a retractable foam hook fire extinguisher. Background Technology

[0002] In the field of fire protection, foam fire extinguishers are widely used in oil and liquid fire scenarios because they can extinguish fires by isolating oxygen through the foam layer. However, traditional foam fire extinguishers have many limitations in actual use and cannot meet the needs of complex fire extinguishing environments. Traditional foam fire extinguishers typically use rigid, fixed-length nozzles, limiting their operational range. When facing fires at heights, such as on top of shelves, in attics, or from distant sources, firefighters must approach the fire to spray, increasing operational risks and potentially delaying extinguishing efforts due to insufficient distance. Furthermore, in confined spaces like pipe rooms, storage corners, or areas with obstacles, the fixed-length nozzle is difficult to maneuver flexibly, hindering precise aiming and reducing extinguishing efficiency. Traditional nozzles also have limited angle adjustment capabilities, often spraying in a single direction. For fires on sloping surfaces or at corners, adjusting the nozzle angle is insufficient for effective coverage, resulting in dispersed foam spray and failure to form a concentrated extinguishing foam layer, thus affecting extinguishing effectiveness. Moreover, the connection between the hose and nozzle in some traditional fire extinguishers is inflexible, prone to twisting and tangling during adjustments or extension, hindering operation and potentially causing excessive bends that impede foam delivery and delay extinguishing. Therefore, improvements are needed to address these issues. Utility Model Content

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figure 1-6 This utility model discloses a retractable foam hook fire extinguisher, comprising a main body 1, a bracket 2 mounted on the side of the main body 1, and a connector 3 mounted on the bottom of the main body 1. The main body 1 facilitates the storage of extinguishing liquid; the bracket 2 facilitates stable placement; and the connector 3 facilitates the connection of different fire extinguishing devices. A delivery hose 4 is connected to the upper end of the main body 1, facilitating the connection between the main body 1 and a telescopic pipe 5. The other end of the delivery hose 4 is connected to multiple sections of the telescopic pipe 5, allowing for adjustment of the device according to the fire intensity. An adjustment mechanism is installed at the other end of the telescopic pipe 5, and the adjustment mechanism is equipped with... The U-shaped nozzle 6 facilitates the spraying of extinguishing materials. The adjustment mechanism includes a connecting hose 12 installed at one end of the telescopic pipe 5. A hinge block 8 is fixed to one side of the connecting hose 12, which facilitates changing the tilt angle of the nozzle 6. The hinge block 8 is hinged to one end of the telescopic pipe 5, and a hinge rod 9 is inserted at the hinge point between the hinge block 8 and the telescopic pipe 5. The hinge rod 9 facilitates the installation of a limiting tooth. A limiting tooth is installed on the hinge rod 9, and a limiting groove for matching the limiting tooth is opened on the hinge block 8. A tension spring 10 is sleeved on the outside of the hinge rod 9, which facilitates the reset of the limiting tooth.

[0015] In this utility model, one end of the tension spring 10 is connected to the inner wall of the limiting groove, and the other end is connected to the convex plate at one end of the hinge rod 9. One end of the connecting hose 12 is inserted into the inner wall of one end of the telescopic tube 5. A connecting ring 11 is installed between the conveying hose 4 and the telescopic tube 5. The connecting ring 11 facilitates the connection between the conveying hose 4 and the telescopic tube 5. One end of the connecting ring 11 is rotatably connected to the conveying hose 4, and the other end of the connecting ring 11 is threadedly connected to the telescopic tube 5. An aerator 7 communicating with the nozzle 6 is installed inside one end of the connecting hose 12. The aerator 7 facilitates the formation of foams of different densities as needed.

[0016] Working principle: When using this utility model, firstly, according to the distance to the fire source, the multi-section telescopic tube 5 is stretched or contracted. The multi-section design of the telescopic tube 5 allows for flexible length adjustment to adapt to different fire extinguishing scenarios such as high places, long distances, or narrow spaces. One end of the connecting ring 11 is rotatably connected to the delivery hose 4, and the other end is threadedly connected to the telescopic tube 5, ensuring that when the length of the telescopic tube 5 is adjusted, the connection between the delivery hose 4 and the telescopic tube 5 is stable and can rotate relative to each other, avoiding hose twisting. The spray angle of the U-shaped nozzle 6 is adjusted by adjusting the mechanism. Pulling the hinge rod 9 causes the limiting tooth on it to disengage from the limiting groove of the hinge block 8, releasing the angle lock. Rotating the hinge block 8 drives the connecting hose 12 and the U-shaped nozzle 6 to adjust to the target angle. Releasing the hinge rod 9 stretches the elastic force of the spring 10, causing the limiting tooth to re-embed into the limiting groove, locking the angle of the nozzle 6. The flexible design of the connecting hose 12 enhances the flexibility of the nozzle 6, allowing it to adapt to fire sources in special locations such as inclined surfaces and corners. The foam liquid is transported from the main body 1 through the delivery hose 4, telescopic pipe 5, and connecting hose 12 to the aerator 7. The aerator 7 fully mixes the foam liquid with air to form fine foam, which is then sprayed out through the U-shaped nozzle 6. The design of the U-shaped nozzle 6 ensures that the foam is sprayed in a concentrated manner, covering the surface of the fire source and extinguishing the fire by isolating oxygen.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
