Description

Technical Field

[0001] This application relates to the field of fire axe technology, specifically a multi-functional fire axe. Background Technology

[0002] Fire axes, as a basic tool for fire rescue, are widely used in various rescue scenarios. The traditional fire axe is mainly used for chopping and demolition, but in actual rescue operations, more functions are often needed to cope with complex rescue environments.

[0003] An existing patent (publication number: CN215433785U) discloses a multifunctional fire axe. It includes an axe head, a conical hammer fixedly connected to the side of the axe head, a threaded groove on the outer surface of the conical hammer, a striking hammer threadedly connected to the outer surface of the conical hammer through the threaded groove, and an axe handle fixedly connected to the lower surface of the axe head, with a first storage groove at the bottom end of the axe handle.

[0004] In the above solution, the external conical hammer is fixed to the striking hammer by threads. However, this threaded connection method has certain inconveniences in actual operation. After aligning the threads, it is necessary to manually rotate and apply a certain force to ensure the stability of the connection. This not only increases the complexity of operation and affects the efficiency of rescue, but also the function of the above solution is relatively simple. However, the situation at the rescue site is complex and diverse. Due to the limited function of the tool, the efficiency of rescue will be affected. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a multi-functional fire axe that has the advantages of chopping, striking, breaking, demolishing, guiding, and quick switching functions, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: An axe handle is included, one end of which is threadedly connected to a connecting end. An axe face is fixedly connected to the outer surface of the connecting end. An axe mouth is fixedly connected to the outer surface of the connecting end. A fixing block is fixedly connected to the outer surface of the connecting end. A rotating shaft is rotatably connected to the inner wall of the fixing block. An installation block is fixedly connected to the outer surface of the rotating shaft. A limiting mechanism is provided inside the fixing block. The limiting mechanism includes a component cavity opened inside the fixing block. Two communicating grooves are opened on the inner wall of the component cavity. A U-shaped plate is slidably connected to the inner wall of the communicating grooves. Two limiting rods are fixedly connected to the outer surface of the U-shaped plate. The outer surface of the limiting rods is inserted into the inner wall of the rotating shaft. A hammer head is fixedly connected to the outer surface of the installation block. A conical hammer is fixedly connected to the outer surface of the installation block. A storage cavity is opened inside the axe handle. An emergency whistle is placed on the inner wall of the storage cavity.

[0007] The above-described scheme, through the interaction of the axe head, mouth opener, pivot, U-shaped plate, limiting rod, mounting block, hammer head, conical hammer, and emergency whistle, enables the fire axe to provide multiple functions such as chopping, striking, breaking, demolition, and early warning positioning. This allows firefighters to cope with various complex environments. Furthermore, the pivot, U-shaped plate, and limiting rod allow for rapid switching between the hammer head and conical hammer as the pivot rotates. When the limiting rod is inserted into the pivot, the switching function is quickly and securely fixed, thereby increasing firefighter efficiency and improving rescue efficiency.

[0008] Furthermore, the insertion hole on the outer surface of the rotating shaft is adapted to the external dimensions of the limiting insertion rod.

[0009] The above scheme, by setting a limiting rod and a rotating shaft, ensures that the size of the through hole on the surface of the rotating shaft matches the size of the limiting rod, so that the limiting rod can fit tightly against the inner wall of the through hole of the rotating shaft, thereby improving the stability of the limiting.

[0010] Furthermore, two springs are fixedly connected to the outer surface of the U-shaped plate, and the end of the spring away from the outer surface of the U-shaped plate is fixedly connected to the inner wall of the component cavity.

[0011] By using the above solution and the action of the spring, the U-shaped plate can be continuously pushed to drive the limiting rod into the through hole of the rotating shaft, thereby ensuring the stable insertion of the limiting rod and improving the stability of the limit.

[0012] Furthermore, the bottom end of the axe handle is threadedly connected to a tail end sealing block, and the inner wall of the tail end sealing block is provided with a compass.

[0013] The above scheme, by setting up a compass, can provide firefighters with a directional positioning function, thus enabling them to identify directions in special environments.

[0014] Furthermore, the inner wall of the axe handle has two placement grooves, and the inner walls of both placement grooves are used to place saw blades.

[0015] By implementing the above solution and setting the function of the saw blade, the fire axe can be used not only for traditional functions such as chopping and striking, but also as a saw when needed, thereby expanding the application range of the fire axe.

[0016] Furthermore, the saw blade and the tail-end sealing block can be fixedly connected by bolts.

[0017] The above solution utilizes the tail-end sealing block and saw blade to quickly connect the tail-end sealing block and saw blade, making it easier for firefighters to use and improving work efficiency.

[0018] Furthermore, emergency medications are placed on the inner wall of the storage cavity.

[0019] The above-mentioned scheme, by setting up emergency medicines, enables emergency rescue in special circumstances, and the storage compartment can store different types of items, thereby improving rescue efficiency.

[0020] Furthermore, two rubber sleeves are fixedly connected to the outer surface of the axe handle.

[0021] The above solution, by setting up a rubber sleeve, can provide good insulation performance and increase friction when firefighters hold it, preventing slippage during use and thus improving safety during use.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This multi-functional fire axe, through the interaction of its axe head, mouth opener, pivot, U-shaped plate, limiting rod, mounting block, hammer head, conical hammer, and emergency whistle, provides multiple functions such as chopping, striking, breaking, demolition, and early warning positioning. This allows firefighters to cope with various complex environments. Furthermore, the pivot, U-shaped plate, and limiting rod enable rapid switching between the hammer head and conical hammer as the pivot rotates, and the limiting rod, when inserted into the pivot, quickly limits and fixes the switching function, thereby increasing firefighter efficiency and improving rescue efficiency.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a multi-functional fire axe includes an axe handle 1. One end of the axe handle 1 is threadedly connected to a connecting end 2. An axe face 3 is fixedly connected to the outer surface of the connecting end 2. An opening tool 4 is fixedly connected to the outer surface of the connecting end 2. A fixing block 5 is fixedly connected to the outer surface of the connecting end 2. A rotating shaft 6 is rotatably connected to the inner wall of the fixing block 5. An mounting block 7 is fixedly connected to the outer surface of the rotating shaft 6. A limiting mechanism 8 is provided inside the fixing block 5. The limiting mechanism 8 includes a component cavity 801 opened inside the fixing block 5. Two communicating grooves 802 are opened on the inner wall of the component cavity 801. The inner wall of the communicating grooves 802 slides. A U-shaped plate 803 is connected, and two limiting rods 804 are fixedly connected to the outer surface of the U-shaped plate 803. The outer surface of the limiting rods 804 is inserted into the inner wall of the rotating shaft 6. A hammer head 9 is fixedly connected to the outer surface of the mounting block 7, and a conical hammer 10 is fixedly connected to the outer surface of the mounting block 7. A storage cavity 13 is opened inside the axe handle 1, and an emergency whistle 16 is placed on the inner wall of the storage cavity 13. Through the interaction of the axe face 3, the mouth opener 4, the rotating shaft 6, the U-shaped plate 803, the limiting rods 804, the mounting block 7, the hammer head 9, the conical hammer 10, and the emergency whistle 16, the fire axe can be used for chopping and striking. This device features multiple functions including striking, breaking, demolition, and early warning positioning, enabling firefighters to handle various complex environments. Through the design of the rotating shaft 6, U-shaped plate 803, and limiting rod 804, the rotating shaft 6 allows for rapid switching between the hammer head 9 and the conical hammer 10. Furthermore, when the limiting rod 804 is inserted into the rotating shaft 6, it quickly limits and fixes the switching function, thereby increasing firefighter efficiency and improving rescue efficiency. The insertion hole on the outer surface of the rotating shaft 6 is adapted to the external dimensions of the limiting rod 804. The combination of the limiting rod 804 and the rotating shaft 6... The through hole on the surface of the rotating shaft 6 is sized to match the size of the limiting rod 804, so that the limiting rod 804 can fit tightly against the inner wall of the through hole of the rotating shaft 6, thereby improving the stability of the limiting. Two springs 805 are fixedly connected to the outer surface of the U-shaped plate 803, and the end of the spring 805 away from the outer surface of the U-shaped plate 803 is fixedly connected to the inner wall of the component cavity 801. By setting the action of the springs 805, the U-shaped plate 803 can always be pushed to drive the limiting rod 804 to be inserted into the through hole of the rotating shaft 6, thereby ensuring the stable insertion of the limiting rod 804 and improving the stability of the limiting.

[0032] Please see Figure 1 and Figure 2 The bottom end of the axe handle 1 is threaded with a tail end sealing block 11. The inner wall of the tail end sealing block 11 is equipped with a compass 12. By setting the compass 12, it can provide firefighters with a directional positioning function, so that firefighters can identify the direction in special environments. The inner wall of the axe handle 1 has two placement slots 14. The inner wall of the two placement slots 14 is equipped with a saw blade 15. By setting the saw blade 15, the fire axe can not only be limited to traditional functions such as chopping and striking, but can also be used as a saw when needed, thereby expanding the application range of the fire axe.

[0033] Please see Figure 1 and Figure 2 The saw blade 15 and the tail-end sealing block 11 can be fixedly connected by bolts. Through the action of the tail-end sealing block 11 and the saw blade 15, the tail-end sealing block 11 and the saw blade 15 can be quickly connected, which is convenient for firefighters to use and can improve work efficiency. The inner wall of the storage cavity 13 is filled with first aid medicines 18. By setting the first aid medicines 18, emergency rescue can be carried out in special situations. The storage cavity 13 can store different types of items, thereby improving rescue efficiency. Two rubber sleeves 17 are fixedly connected to the outer surface of the axe handle 1. By setting the rubber sleeves 17, good insulation performance can be provided and friction can be increased when the firefighter holds the handle, preventing the hand from slipping during use, thereby improving safety during use.

[0034] This embodiment of a multifunctional fire axe, through the interaction of the axe head 3, the mouth opener 4, the rotating shaft 6, the U-shaped plate 803, the limiting rod 804, the mounting block 7, the hammer head 9, the conical hammer 10, and the emergency whistle 16, can provide multiple functions such as chopping, striking, breaking, demolition, and early warning positioning. This allows firefighters to cope with various complex environments. Furthermore, the rotating shaft 6, U-shaped plate 803, and limiting rod 804 allow for rapid switching between the hammer head 9 and the conical hammer 10 as the shaft 6 rotates. When the limiting rod 804 is inserted into the rotating shaft 6, the switching function is quickly limited and fixed, thereby increasing the firefighter's work efficiency and improving rescue efficiency.

[0035] It should be noted that the shaft 6 and mounting block 7 are made of high-strength rigid material, which can provide strong support during use and ensure the stable use of hammer head 9 and conical hammer 10.

[0036] The working principle of the above embodiment is as follows: When using this device, the axe head 3 and the mouth opener 4 first provide the fire axe with chopping and breaking functions. Then, the rotation of the shaft 6 allows for quick switching between the hammer head 9 and the conical hammer 10. After switching, the U-shaped plate 803 is always driven by the spring 805, which in turn drives the limiting rod 804 to be inserted into the through hole of the shaft 6, thus ensuring the stable insertion of the limiting rod 804. When the limiting rod 804 is inserted into the interior of the shaft 6, it can quickly limit and fix the switching function, thereby increasing the work efficiency of firefighters. Then, the connecting end 2 and the axe handle 1 can be detached, thereby reducing the overall size of the device and making it easy to carry. Finally, the tail sealing block 11 is quickly connected to the saw blade 15, so that the fire axe is not limited to traditional functions such as chopping and striking, but can also be used as a saw when needed. Then, the first aid medicine 18 enables firefighters to carry out emergency rescue in special situations, and the storage cavity 13 can store different types of items, thereby improving rescue efficiency.
