Description

Technical Field

[0001] The utility model relates to the technical field of personal protective equipment, in particular to an air respirator suspension device. Background Art

[0002] Air respirators are a type of personal protective equipment, usually used to provide clean, breathable air for firefighters and emergency rescue personnel during firefighting or emergency rescue operations, so that they can safely operate in environments with toxic and harmful gases, dense smoke, lack of oxygen or other hazards to the respiratory system. Air respirators are mainly composed of gas cylinders, decompression systems, air supply valves, full-face masks or half-face masks, back frames and straps, pressure gauges, alarm devices, quick connectors and pipelines. Usually, depending on the length of the rescue, multiple gas cylinders will be prepared for firefighters so that they can replace new gas cylinders in time and continue to fight and rescue.

[0003] Respirator cylinders are an important part of personal protective equipment. They are usually used to store compressed air to provide clean and safe breathing air for firefighters, rescue workers, and people working in toxic and hazardous gas environments or oxygen-deficient environments. These cylinders are designed to withstand high pressures and work with the entire respirator system to ensure that users can breathe normally in hazardous environments. The cylinder volume is usually between 6.8L and 9L, and the working pressure can reach 30MPa.

[0004] When storing multiple gas cylinders on a fire truck, they are usually stored in an equipment box and placed separately from other equipment in an orderly manner, convenient for access, and maximize space utilization. This requires a storage device to be installed to securely place the respirator cylinders.

[0005] Most fire-fighting manufacturers place the pressure reducing valve in random spaces and inside plastic cylinders. This has a simple structure and no shock-proof or buffering components. During the driving of the fire truck, it is very easy to bump into something and damage the pressure reducing valve. Utility Model Content

[0006] The main purpose of the utility model is to provide an air breathing apparatus suspension device, which can effectively solve the problem that fire manufacturers use random space to insert gaps to place it inside a plastic cylinder, which has a simple structure and no shock-proof buffer components. It is very easy to bump into it during the driving of the fire truck, thereby damaging the pressure reducing valve.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An air respirator suspension device comprises an equipment rack, wherein two respirator brackets are fixed at the lower end of the equipment rack, and throat clamps are fixed at the lower ends of the two respirator brackets. A plastic straight cylinder is commonly fixed to the inner surfaces of the two throat clamps, and a buffer ring is also fixed to the front side of the inner surface of the plastic straight cylinder. A limiting component for limiting the position of a gas cylinder is also provided below the outer surface of the plastic straight cylinder.

[0009] Preferably, the limiting assembly comprises a mounting box fixed below the outer surface of the plastic straight cylinder, a baffle is rotatably mounted on the inner surface of the mounting box, and a torsion spring is further provided at the rotational connection between the baffle and the mounting box.

[0010] Preferably, the installation box is communicated with the interior of the plastic straight cylinder.

[0011] Preferably, when the torsion spring is in a natural state, the side of the baffle away from the buffer ring is inclined toward the side close to the central axis of the plastic straight cylinder.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model adopts the design of equipment rack, so that the device can be hung on the top of the equipment box when in use, which can improve the space utilization rate of the equipment box. At the same time, the design of buffer ring can reduce the wear between the gas cylinder and the plastic straight cylinder, and extend the service life of the device.

[0014] 2. The utility model adopts the design of a limit assembly, which can facilitate the taking and placing of gas cylinders through the mutual cooperation between the baffle and the torsion spring. At the same time, it can also limit the gas cylinders to prevent the gas cylinders from falling off during transportation, thereby affecting the normal operation of the device, making the device more stable when transporting gas cylinders.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1 and Figure 2 As shown, an air respirator suspension device includes an equipment frame 1, which is a prior art. When the device is in use, the equipment frame 1 can be assembled with an aluminum profile frame, which can facilitate the device to be hung on the top of the equipment box, thereby improving the space utilization rate of the equipment box. Two respirator brackets 2 are fixed at the lower end of the equipment frame 1, and throat clamps 3 are fixed at the lower ends of the two respirator brackets 2, wherein the respirator brackets 2 are used to facilitate the installation of throat clamps 3, which are prior art and convenient for the installation of plastic straight cylinders 4. The inner surfaces of the two throat clamps 3 are commonly fixed with plastic straight cylinders 4 for storing gas cylinders, and a buffer ring 5 is also fixed on the front side of the inner surface of the plastic straight cylinder 4. The buffer ring 5 is made of a soft elastic material, which is used to prevent the operator from generating a large friction between the gas cylinder and the plastic straight cylinder 4 when placing the gas cylinder, causing wear to the gas cylinder or the plastic straight cylinder 4, thereby affecting the normal operation of the device, and a limiting component 6 for limiting the gas cylinder is also provided below the outer surface of the plastic straight cylinder 4.

[0022] like Figure 2 As shown, the limiting assembly 6 includes a mounting box 7 fixed below the outer surface of the plastic straight tube 4, and the mounting box 7 is used for installing the baffle 8. Figure 3 and Figure 4 As shown, the installation box 7 is communicated with the inside of the plastic straight tube 4, so that the baffle 8 can limit the gas cylinder when the device is in use. The baffle 8 for limiting the gas cylinder is rotatably installed on the inner surface of the installation box 7. A torsion spring 9 is also provided at the rotating connection between the baffle 8 and the installation box 7. The torsion spring 9 is a prior art, and its installation method is a conventional design in the prior art, so the utility model will not be described in detail.

[0023] like Figure 3 and Figure 4 As shown, when the torsion spring 9 is in a natural state, the side of the baffle 8 away from the buffer ring 5 is inclined toward the side close to the central axis of the plastic straight cylinder 4. Due to the inclined design of the plastic straight cylinder 4, when the gas cylinder is placed in the plastic straight cylinder 4, the baffle 8 can rotate counterclockwise, so that the gas cylinder can be easily pushed into the plastic straight cylinder 4. At the same time, due to the design of the torsion spring 9, the baffle 8 can limit the gas cylinder when it is in an inclined state, preventing the gas cylinder from slipping out of the plastic straight cylinder 4 during transportation, thereby affecting the transportation of the gas cylinder.

[0024] When the operator pushes the gas cylinder into the equipment rack 1, the gas cylinder will press the baffle 8 to rotate, further making the baffle 8 contact with the gas cylinder, making the baffle 8 parallel to the axis of the plastic straight cylinder 4, so that the gas cylinder can be stored in the plastic straight cylinder 4. At the same time, due to the design of the torsion spring 9, the baffle 8 can be rotated back to an inclined state when the gas cylinder is not in contact with the baffle 8, and further making the baffle 8 limit the gas cylinder when the device is in use, thereby preventing the gas cylinder from slipping out of the plastic straight cylinder 4 when the device is transporting the gas cylinder.

[0025] The specific implementation method of this embodiment is as follows: when the device is in use, the equipment rack 1 is first fixed to the top surface of the equipment box, and then the plastic straight cylinder 4 is installed between the two throat hoops 3. When the operator needs to store the gas cylinder, he only needs to place the gas cylinder in the plastic straight cylinder 4. When the operator pushes the gas cylinder into the equipment rack 1, the gas cylinder presses the baffle 8 to rotate, and further makes the baffle 8 contact with the gas cylinder, so that the baffle 8 and the axis of the plastic straight cylinder 4 are parallel, so that the gas cylinder can be stored in the plastic straight cylinder 4. At the same time, due to the design of the torsion spring 9, the baffle 8 can be rotated to an inclined state when the gas cylinder is not in contact with the baffle 8, and further enables the baffle 8 to limit the gas cylinder when the device is in use, thereby preventing the gas cylinder from slipping out of the plastic straight cylinder 4 when the device is transporting the gas cylinder.

[0026] When the gas cylinder needs to be taken out, the operator first manually presses down the baffle 8 to make the baffle 8 parallel to the central axis of the plastic straight cylinder 4, and then pulls out the gas cylinder (when the gas cylinder is in contact with the baffle 8, the operator does not need to press the baffle 8 with his hands). When the gas cylinder is not in contact with the baffle 8, due to the design of the torsion spring 9, the baffle 8 will return to the inclined state, which is convenient for the next use of the device.

[0027] It should be noted that the specific installation method, circuit connection method and control method of the throat clamp 3, plastic straight tube 4 and torsion spring 9 in the utility model are all conventional designs and are not elaborated in detail in the utility model.

[0028] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
