Technical Field

[0001] This utility model relates to the field of fire extinguishing and rescue wrench technology, specifically a multi-functional fire extinguishing and rescue wrench. Background Technology

[0002] Fire wrenches are frequently used by firefighters in their daily work. Currently, commonly used fire wrenches can only perform one or a few functions. When dealing with complex situations, different wrenches and tools are needed for installation, disassembly, opening and closing, which increases the burden on firefighters. Therefore, a multi-functional wrench is needed to facilitate the use of firefighters.

[0003] However, existing fire extinguishing and rescue wrenches only add the shape or model of the wrench to prevent firefighters from frequently changing wrenches, and do not have other functions.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN219747778U discloses a multi-functional wrench tool for fire fighting, comprising a wrench body with an arc-shaped wrench at one end. The wrench body also includes a window breaker and a cutter. A cross-shaped protruding wrench is located on the side of the wrench body near the arc-shaped wrench. A wrench seat is rotatably mounted on the end of the wrench body, and a ratchet is mounted on the wrench seat. A mounting cavity is formed on the wrench body, and a pawl is installed within the mounting cavity. The pawl engages with the ratchet. The wrench body is located near... The ratchet wrench is equipped with a handle; the window breaker is a window breaker cone, which integrates the functions of the supporting tools needed by firefighters to handle emergencies in their daily work. It can break vehicle windows and cut seat belts, greatly improving the work efficiency of firefighters. It also has the functions of opening underground fire hydrant covers, opening and closing fire hydrants, connecting and disconnecting fire suction pipes, opening and closing foam tanks, and closing liquefied gas valve cores. It has high practicality and can be widely used in firefighting operations.

[0005] The aforementioned device facilitates the breaking of glass using a window breaker, improving the rescue efficiency of firefighters. However, the device only adds functionality for normal rescue work, with limited expansion for firefighting, and cannot meet the needs of firefighting situations. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-functional fire extinguishing and rescue wrench to solve the problem mentioned in the background art that the limited fire extinguishing function affects the efficiency of personnel rescue.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional fire extinguishing and rescue wrench, comprising a wrench body, a handle fixedly installed on the outer surface of the wrench body, an arc-shaped wrench provided at the head of the wrench body, and a small wrench fixedly installed on the side of the wrench body away from the head; an outdoor water pump connector bolt is provided on the inner side of the wrench body, and fire-fighting components for easy fire extinguishing are provided on the outer surface of the wrench body.

[0008] Furthermore, the outer surface of the grip is provided with an anti-slip sleeve, which is made of fire-retardant material.

[0009] Furthermore, an outdoor fire hydrant key is provided on the side of the wrench body near the arc-shaped wrench, and the outdoor fire hydrant key has an internal thread groove.

[0010] Furthermore, an indoor fire hydrant pressure relief bolt is provided on the side of the wrench body near the small wrench, and the indoor fire hydrant pressure relief bolt fits tightly with the pressure relief port.

[0011] Furthermore, the fire-fighting component includes a hose disconnect interface, which is fixedly installed on the outer surface of the wrench body.

[0012] Furthermore, a window breaker is provided on the side of the wrench body near the curved wrench. The window breaker is designed as a window breaker cone, and an axe blade is provided on the side of the wrench body away from the window breaker.

[0013] Furthermore, the wrench body has a detachable screw handle on the side near the small wrench, which can be used to remove screws of different sizes.

[0015] (1) The arc-shaped wrench and small wrench can be used to install and remove nuts of different sizes, and the outdoor water pump connector bolt can be opened quickly using the outdoor water pump connector bolt. The anti-slip sleeve on the handle reduces the risk of hand slippage, and the fire-fighting components improve the efficiency of fire fighting and rescue, thus promoting the integration of multiple functions to improve fire fighting and rescue capabilities.

[0016] (2) The anti-slip sleeve on the hand grip is designed to reduce slippage when used by personnel and increase friction on the hand, thereby facilitating the exertion of force by firefighters. The anti-slip sleeve is made of fireproof material, mainly flame-retardant fiber, which has excellent high temperature resistance and flame retardant properties. The surface is also coated with aluminum glue to enhance its ability to reflect heat radiation, making it convenient for firefighters to use at the fire scene.

[0017] (3) The key opening of the outdoor fire hydrant is 0.5cm wide, which can quickly open the fire hydrant outlet and facilitate personnel to connect the water supply pipeline. The pressure relief bolt of the indoor fire hydrant can be used to adjust the pressure relief value of the indoor pressure relief valve so as to achieve the pressure value required by the system design.

[0018] (4) The 40mm / 65mm / 80mm hose connectors on the fire hydrant can be removed by the set hose removal interface. The window breaker can be used to break glass such as car windows or doors. The sharpened axe blade can break through obstacles such as wood, doors, windows, and locks to open up a passage for rescue operations. The screw handle can be used to quickly remove screws and nuts of different sizes. It can be used in various environments such as fire rescue sites, narrow spaces, and training grounds. The screw handle includes a through shaft and multiple chain-shaped washers to adjust nuts of different sizes. It is easy to place in the equipment box of the fire fighting vehicle and carry on the firefighter's belt. It is simple to operate, has complete functions, and is convenient to use, which improves the fire fighting and rescue capabilities of the fire rescue team. Attached Figure Description
