Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment technology, and in particular to a multifunctional fire hook. Background Technology

[0002] Fire hooks are an indispensable tool for firefighters at fire scenes. Their design and function enable them to play a crucial role in a variety of emergency situations. The most common use is clearing flammable materials, such as removing burning furniture, debris, or other obstacles to prevent the fire from spreading or to clear a path for firefighters. In addition, fire hooks are often used to break down ceilings to check for hidden fire spots or paths for smoke to spread, which is essential for controlling the fire and ensuring personnel safety. Besides clearing and breaking down, fire hooks can also be used to pull electrical wires, especially when the wires may pose a risk of electric shock. By safely pulling the wires away from the danger zone, firefighters can reduce the risk of accidents and create a safer environment for other rescue operations.

[0003] To better adapt to fire scenes and effectively clear obstacles, existing fire hooks typically employ a hook-like structure to cut or pull out obstacles such as electrical wires. For example, Chinese Patent Publication No. CN219558549U discloses "a fire hook" in which the curved hook portion hooks onto an obstacle, and the straight rod is pulled back to remove burning materials, obstacles, and coverings. If an object is obstructing the removal, the blade on the inner side of the curved hook portion can cut the obstruction. If it still cannot be cut, the straight rod is pulled back and forth by the straight saw portion to saw through the obstruction. This helps to quickly remove burning materials, obstacles, and coverings. After digging, watering helps to completely extinguish the fire and improves fire extinguishing efficiency.

[0004] However, in actual use, the blade of the hook part tends to become dull after long-term use, affecting the cutting effect. At the same time, the hook part is inevitably contaminated when breaking through obstacles, which can easily lead to rust. Removing and installing the hook part is difficult, and usually the entire fire hook is replaced, resulting in a waste of resources. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the hook part being inevitably contaminated and corroded during obstacle breaking, the difficulty in removing and installing the hook part, and the fact that the entire fire hook usually needs to be replaced, resulting in resource waste. Therefore, a multifunctional fire hook is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a multifunctional fire hook, including a rod and two hooks. The front end of the rod is provided with a spike. Each hook is fixedly provided with a connecting cover, which is attached to the outer wall of the rod. A fixing cover is slidably provided on the rod and is threadedly connected to the connecting cover. A handle is provided on one side of the rod. A positioning post is fixedly provided on the connecting cover. An insertion hole is provided on the rod to cooperate with the positioning post. A positioning component is provided inside the rod to cooperate with the positioning post. A driving part is provided on one side of the handle to cooperate with the positioning component.

[0008] Furthermore, a drive rod is provided on one side of the drive unit, the drive rod passing through the handle and connected to the positioning member.

[0009] Furthermore, the positioning component has a positioning groove, the positioning post is inserted into the positioning groove, and each positioning post has a slot, which engages with the positioning groove.

[0010] Furthermore, a torsion spring is provided inside the rod body, the other end of the torsion spring is connected to the drive rod, and a limiting ring that cooperates with the positioning member is fixedly provided inside the rod body.

[0011] Furthermore, the rod body includes a main rod fixedly connected to the handle, a support rod movably inserted into the main rod, and the hook and the fixing cover are both disposed on the support rod.

[0012] Furthermore, both the main rod and the support rod are fixedly provided with screw holes, and the support rod is also provided with a threaded part for threaded connection of the screw holes.

[0013] The multifunctional fire hook proposed in this utility model has the following advantages:

[0014] In this utility model, the connecting cover and the hook body are fixed by setting a fixing cover and a connecting cover to cooperate, and the connecting cover and the hook body are further fixed by setting a positioning component and a positioning post to cooperate, so as to prevent them from falling off when breaking through obstacles.

[0015] Secondly, in this utility model, when the positioning groove engages with the slot on the positioning post, the positioning post is fixed. At this time, the connecting cover and the hook cannot be removed. The positioning component is rotated by the rotation drive to control the position of the positioning groove. When the positioning groove and the slot on the positioning post are misaligned, the connecting cover and the hook can be removed and replaced, avoiding the waste caused by replacing the entire fire hook, and at the same time facilitating careful cleaning and maintenance of the hook.
