Problems solved by technology

[0003] The head of the fire shovel is made of steel, and the handle is usually made of wood or iron. Since the length of the handle of the fire shovel is usually fixed when it leaves the factory, the length of the handle cannot be adjusted according to the needs of different firefighters. Adjustment, this will virtually reduce the combat effectiveness of firefighters, and the handle and head of the fire shovel cannot be removed conveniently after us...

Abstract

The invention discloses a novel fire-fighting shovel and belongs to the field of fire-fighting apparatuses. The novel fire-fighting shovel comprises a shovel head and a handle mounted on the shovel head. The handle is connected with the shovel head through a threaded structure. The handle comprises four structural segments with axial protrusions at the front ends and internal thread holes in the rear ends, and the four structural segments are connected with one another through threaded structures. The handle further comprises a handle cap which is detachably mounted at the rear end of the fourth structural segment through a threaded structure. Flexible structural layers are arranged between the first structural segment and the second structural segment, between the second structural segment and the third structural segment and between the third structural segment and the fourth structural segment. The fire-fighting shovel can be disassembled and assembled at the later stage as required so as to change length of the handle, and the whole handle can be conveniently and fast separated from a shovel body.

Example Embodiment

[0024] Example 1
[0025] Such as Figure 1-3 As shown, a new type of fire fighting shovel in this embodiment includes a shovel head 1 and a handle 2 mounted on the shovel head, and the handle and the shovel head are connected to each other through a threaded structure. The handle includes: first, second, third, and fourth structural sections.
[0026] Wherein, the cylindrical first structure section 20 has an axial protrusion 20a fitted with the shovel head and with an external thread structure at its front end, and a first internal thread hole is provided at the center of the rear end of the first structure section. The rear end surface of the first structure section is provided with a first annular groove co-centered with the first internal threaded hole.
[0027] The cylindrical second structure section 21 has a second protrusion 21a cooperating with the first internal threaded hole arranged axially at its front end, the second protrusion is provided with an external thread structure, and the front end surface of the second structure section is provided with There is a second annular protrusion 21b arranged co-center with the second protrusion, the second annular protrusion is installed in the first annular groove, and a second internal threaded hole is provided at the center of the rear end of the second structure section, The rear end surface of the second structure section is provided with a second annular groove co-centered with the second internal threaded hole.
[0028] The cylindrical third structure section 22 is axially arranged with a third protrusion 22a cooperating with the second internal threaded hole, the third protrusion is provided with an external thread structure, and the front end surface of the third structure section is provided There is a third annular protrusion 22b arranged co-center with the third protrusion, the third annular protrusion is installed in the second annular groove, and a third internal threaded hole is provided at the center of the rear end of the third structure section, The rear end surface of the third structure section is provided with a third annular groove co-centered with the third internal threaded hole.
[0029] The cylindrical fourth structure section 23 has a fourth protrusion 23a cooperating with the third internal threaded hole arranged axially at its front end, the fourth protrusion is provided with an external thread structure, and the front end surface of the fourth structure section is provided There is a fourth annular protrusion 23b arranged co-centrically with the fourth protrusion, the fourth annular protrusion is installed in the third annular groove, and a fourth internal threaded hole is provided in the center of the rear end of the fourth structural section, The rear end surface of the fourth structural section is provided with a fourth annular groove co-centered with the fourth internal threaded hole.
[0030] The handle cap 3 is detachably installed at the rear end of the fourth structural section through a threaded structure. The handle cap can prevent the firefighters' hands from being hung on the scene such as burrs at the rear end of the different structural sections. The handle cap has an outer strap inside. The threaded protrusion can be easily installed on the corresponding structural section through the threaded structure.
[0031] In order to prevent the problem of hand gripping due to gaps between different structural sections, between the first structural section and the second structural section, between the second structural section and the third structural section, and the third structural section and the fourth structure A flexible structural layer 4 is provided between the segments.
[0032] The flexible structural layer is a ring-shaped structural member whose main body is made of rubber material, and the flexible structural layer has an inner ring portion 4a made of magnetic material, and the first, second, third, and fourth structural sections adopt It is made of metal material that can be mutually adsorbed with the inner ring part. After the flexible structure layer of the ring structure is sleeved in place, it can be adsorbed onto two adjacent metal handles through a magnet.
[0033] The above-mentioned handle 2 is provided with a control box, and the inside of the control box is provided with a temperature sensor, a central processing unit, a memory, and an air conditioner infrared transmitter. The central processing unit is respectively connected with the temperature sensor, memory, and air conditioner infrared transmitter. The device is electrically connected. When working, the temperature sensor obtains the data of the ambient temperature and transmits it to the central processing unit, the central processing unit saves the data to the memory, and the memory stores the data and feeds it back to the central processing unit. When the ambient temperature is too high or too low, the central processing unit will transmit the binary signal to the air conditioner infrared transmitter. The air conditioner infrared transmitter encodes and modulates the binary signal into a series of pulse signals, and transmits the infrared signal through the infrared transmitter tube, and then the air conditioner The infrared receiver converts the received infrared signal into an electrical signal, then sends it to the demodulation circuit for demodulation after amplifying, filtering, etc., and then returns to a binary signal and outputs it to the air conditioner processor, so that the air conditioner can be intelligently started to adjust the surroundings Ambient temperature.
[0034] A new type of fire fighting shovel in this embodiment overcomes the functional deficiencies of existing devices, can monitor the temperature of the surrounding environment in real time, and can intelligently start the air conditioner when the ambient temperature is too high or too low, thereby ensuring that people are always there In a suitable environment, people's health is well promoted.
