Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, and in particular to a No. 4 multi-functional fire axe. Background Technology

[0002] In fire and rescue operations, personnel have clearly defined roles. The fourth position, also known as the mobile pump operator, is primarily responsible for locating nearby natural water sources, setting up mobile pump supply positions, ensuring sufficient water supply for vehicles, and assisting in completing the mission. They also perform breaching and rescue operations, erecting aerial ladders, operating water distributors, and assisting the second position operator. Simultaneously, they help the third position operator lay water hoses, assist the driver in connecting suction pipes, locate water sources, organize water supply, maintain fire scene security, and collect and inventory used equipment. The fire axe, a commonly used basic piece of equipment for the fourth position operator, directly impacts rescue efficiency and operational safety.

[0003] Currently, existing fire-fighting axes have relatively limited functionality, mostly only possessing basic demolition capabilities such as chopping and splitting. In actual fire station operations, various complex needs are often encountered, requiring multiple devices to handle different scenarios. For example, fire hydrant opening wrenches, door-breaking axes, and rappelling equipment are needed. However, carrying multiple devices can easily lead to insufficient physical strength and time required for switching between devices, thus affecting the efficiency of fire rescue. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model provides a No. 4 multi-functional fire axe that combines the functions of a waist axe for chopping and demolition, multi-valve compatibility, fire hydrant opening, and quick-descent anchor point, while also achieving lightweight design and portability. To solve the above technical problems, this utility model provides the following technical solution:

[0005] A No. 4 multi-functional fire axe includes an axe body, which includes a handle and an axe head located at the upper end of the handle. The axe body is provided with a bolt hole group, which includes at least two different bolt hole sizes. A fire hydrant valve sleeve is detachably connected to the lower end of the axe body. One end of the axe head is provided with a pry head. After the fire hydrant valve sleeve is separated from the axe body, it cooperates with the pry head to open the fire hydrant.

[0006] Based on the above technical solution, the present invention may also adopt the following further technical solutions:

[0007] The axe has an axe blade at the end opposite to the pry bar.

[0008] The axe has a first bolt hole, a second bolt hole, and a third bolt hole between the axe blade and the pry head. The first bolt hole, the second bolt hole, and the third bolt hole are interconnected to form an irregularly elongated bolt hole position.

[0009] The opening of the pry head has a fourth bolt hole and a fifth bolt hole adjacent to each other, and a triangular partition is formed between the fourth bolt hole and the fifth bolt hole.

[0010] The handle has an outward protrusion on its upper side, and a continuous bent straight edge is provided between the protrusion and the axe blade to form a sixth bolt hole.

[0011] The diameters of the first, second, third, fourth, fifth, and sixth bolt holes are all different. Each bolt hole corresponds to a different bolt size, meeting the needs of various scenarios. For example, it can use the most commonly used 8 / 10 / 12 / 14 / 16 / 18 size hexagonal screws. However, for hexagonal screws larger than 20mm, a professional wrench is recommended due to torque considerations. Furthermore, the axe features a scale for each bolt, allowing for intuitive opening of different bolt sizes without trial and error.

[0012] The handle has a knot hole that runs through it. The knot hole not only helps to reduce the weight of the axe, but it can also be used as a connection hole for the rappelling rope. After the rappelling rope and the knot hole are assembled, the axe can be used as a rappelling anchor point.

[0013] The lower end of the handle has a first external thread, and the upper end of the fire hydrant valve sleeve has an internal thread. The fire hydrant valve sleeve is threadedly connected to the handle. The handle has a recessed portion near the first external thread. The recessed portion serves as a stress point, which can increase the chopping force.

[0014] A pry bar is provided below the first external thread of the handle. Both sides of the pry bar have inclined surfaces that slope from the first external thread towards the center, forming a flat pry surface at the lower end of the pry bar. A groove is provided in the center of the pry bar. The flat pry surface of the pry bar makes it easier to insert into narrower gaps, which is beneficial for opening modern security doors. The groove in the middle has the effect of removing nails.

[0015] The fire hydrant valve sleeve has a second external thread, and a threaded cavity is formed at the lower part of the sleeve. The inner wall of the threaded cavity is an irregularly shaped cavity wall to form a seventh bolt hole. A positioning window is provided above the second external thread on the fire hydrant valve sleeve. A rubber sleeve is fitted over the fire hydrant valve sleeve, and an anti-loss rope can be provided on the rubber sleeve. The seventh bolt hole can be adapted to existing five-hole or six-hole bolts.

[0016] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0017] This utility model's No. 4 fire axe combines existing tools to meet the needs of multi-functional and multi-scenario applications. The axe head has functions of chopping, hacking, chiseling, cutting, hooking, scratching, and prying. Various screw openings are designed in the middle and back of the axe head, such as the commonly used 8 / 10 / 12 / 14 / 16 / 18 hexagonal screw openings. Simultaneously, the double holes in the axe handle can be easily used in emergencies to create a simple descent system as a descent speed controller via rope knots. It is multifunctional and eliminates the need to switch between multiple tools. This utility model's axe is integrally cut and molded, resulting in a stable structure. Attached Figure Description
