Description

Technical Field

[0001] The utility model belongs to the technical field of emergency rescue, and in particular relates to a connection structure for an air respirator and a rescue tool. Background Art

[0002] In the field of emergency rescue, facing emergencies like fires, earthquakes, and natural disasters, time is of the essence, and every second can mean the difference between life and death. Therefore, rescuers must quickly and efficiently utilize a variety of tools to break through obstacles in order to reach and rescue trapped victims. Traditional rescue tools, in addition to those relying on the explosive force of gunpowder, are increasingly powered by electricity or other energy sources, such as electric shovels. These tools play an irreplaceable role in the rescue process.

[0003] However, while positive pressure respirators provide breathing safety for rescuers, effectively connecting these power tools to the respirator's gas cylinders, so that the high-pressure gas inside can be used to supply the tools, has become a pressing issue. Traditional connection methods, such as using complex piping systems or specialized adapters, are not only cumbersome and time-consuming, but also prone to operator errors in emergency situations, resulting in loose connections or gas leaks, which can affect rescue efficiency and safety.

[0004] Furthermore, due to the complex and ever-changing environment at the rescue site, rescuers need to frequently move and change tools. This requires the connection structure to be able to quickly connect and disconnect to reduce the time wasted on tool changes. Furthermore, during the disconnection process, the connection structure also needs to have an automatic pressure-maintaining function to prevent the sudden release of high-pressure gas, which could cause accidental injury to rescuers or waste valuable rescue resources.

The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figure 1-4 shows: a connection structure for an air respirator and a rescue tool, comprising an air source hose 1, both ends of the air source hose 1 are sleeved on a connecting joint 2, the connecting joint 2 is threadedly connected to a connecting joint 3, the connecting joint 2 and the connecting joint 3 both comprise an outer shell 21, the inner wall of the outer shell 21 is connected to a support frame 22, one end of the support frame 22 is connected to a fixing seat 23, a sliding rod 25 is slidably inserted on the fixing seat 23, one end of the sliding rod 25 is connected to a conical plug 26, a spring 24 is sleeved on the outside of the sliding rod 25, the other end of the conical plug 26 is connected to a push rod 27, the connecting joint 2 and the connecting joint The conical plug 26 in the second 3 is respectively adapted to be installed in the conical tube 28 and the conical cavity 31. The conical tube 28 and the conical cavity 31 are respectively formed at one end of the outer shell 21 in the connecting joint 1 2 and the connecting joint 2 3. The other ends of the conical tube 28 and the conical cavity 31 in the connecting joint 1 2 and the connecting joint 2 3 are provided with a pagoda joint 20 and a quick joint 32. The setting of the connecting joint 1 2 and the connecting joint 2 3 realizes the rapid docking of the gas cylinder and the wind shovel, which significantly shortens the rescue preparation time; when the wind shovel is separated from the gas cylinder, the automatic pressure maintaining function of the connecting joint 1 2 and the connecting joint 2 3 effectively prevents gas leakage, thereby improving the safety and reliability during the rescue process. The axis of the slide rod 25 is collinear with the axis of the outer shell 21, and the slide rod 25 cooperates with the fixed seat 23 to guide and support the conical plug 26, so that the conical plug 26 can move stably in the axial direction of the outer shell 21. The support frame 22 is a cross-bracket structure, and the gas can flow smoothly through the groove body on the side of the support frame 22. The inclination of the inner wall of the conical cavity 31 and the conical tube 28 is the same as the inclination of the conical plug 26. The conical plug 26 can fit and seal the conical cavity 31 and the conical tube 28 to achieve automatic pressure maintenance and prevent gas leakage. The spring 24 is slidably sleeved on the outside of the slide rod 25 between the fixed seat 23 and the conical plug 26, and the spring 24 plays a role in The elastic support can effectively support and press the conical plug 26 to seal the conical cavity 31 and the conical tube 28. The outer shell 21 in the connecting joint 2 is provided with an internal thread structure at one end facing away from the pagoda joint 20, and the outer shell 21 in the connecting joint 2 3 is provided with an external thread structure at one end facing away from the conical cavity 31. The connecting joint 1 2 and the connecting joint 2 3 can be stably and quickly connected through the threaded structure. A rubber sealing ring is clamped between the outer shell 21 in the connecting joint 1 2 and the outer shell 21 in the connecting joint 2 3. The rubber sealing ring is elastically deformed after being squeezed by the outer shells 21 on both sides, effectively sealing the connection between the connecting joint 1 2 and the connecting joint 2 3.

[0035] The working principle of this technical solution is as follows: the two connecting joints 2 3 are quickly connected to the gas outlet of the gas cylinder and the gas inlet of the wind shovel through the quick connector 32; the two ends of the gas source hose 1 are put on the pagoda connector 20 and locked with a clamp; when it is necessary to dismantle and rescue, the connecting joint 2 3 is threadedly connected with the connecting joint 1 2; when the connecting joint 1 2 and the connecting joint 2 3 are threadedly connected, the push rods 27 in the connecting joint 2 3 and the connecting joint 1 2 move toward each other and push each other, thereby driving the conical plugs 26 in the connecting joint 2 3 and the connecting joint 1 2 to move in the opposite direction, The conical plug 26 is moved inside the conical tube 28 and the conical cavity 31, so that the gas can flow smoothly through the connecting joint 1 2 and the connecting joint 2 3 to supply air to the wind shovel; during the movement, the conical plug 26 is limited by the slide bar 25 and the fixed seat 23 so as to move stably; when the connecting joint 1 2 and the connecting joint 2 3 are separated, the spring 24 releases the elastic potential energy, driving the conical plug 26 to return to its original position and move to block in the conical cavity 31 and the conical tube 28, thereby sealing the gas. There is no need to use a valve, and the gas can be quickly circulated or blocked by connecting and disassembling the pipeline.
