Description

Technical Field

[0001] This utility model relates to an inflation device, and more particularly to an inflation device for rubber boats with dual inflation connections, belonging to the field of fire-fighting equipment and emergency rescue technology. Background Technology

[0002] In forest firefighting, rubber boats are mainly used to overcome terrain limitations by utilizing water resources, and undertake key tasks such as personnel transportation, material supply, and fire assistance. They are especially suitable for complex scenarios in forests where there are rivers, lakes, swamps, reservoirs and other water bodies.

[0003] Forest firefighting often faces difficulties in land access (such as dense forests, ravines, and steep slopes). Rubber boats can use waterways to create efficient channels. Their core purpose is the rapid transfer and deployment of personnel. For areas around waterways in forests or isolated trapped points (such as lake islands surrounded by fire or the opposite bank of a river), rubber boats can quickly reach and transfer trapped people, forest rangers, or missing persons, avoiding delays in rescue due to blocked land routes. They can also deploy firefighters to fire areas near remote waterways, reducing the physical exertion of firefighters traversing complex terrain on foot, allowing teams to quickly reach the core of the fire and gain more time for firefighting.

[0004] Rubber boats are highly stable and have minimal turbulence, making them suitable for transporting injured firefighters or civilians within waterways. When paired with first-aid equipment (such as stretchers and first-aid kits), they can buy valuable time for the injured to receive treatment. Rubber boats require rapid inflation during use, making an inflation device an essential component for inflating them.

[0005] For example, a quick inflation device for an inflatable boat disclosed in application number 202420639201.5 includes an air supply pipe and a connecting pipe. The front end of the air supply pipe is connected to an air supply connector, and the rear end of the air supply pipe is equipped with a quick connector assembly. The air supply pipe is connected to the connecting pipe through the quick connector assembly, and the other end of the connecting pipe is connected to an air supply interface. Based on the search, it can be found that the prior art can be quickly connected, but the inflation pressure of the inflatable boat cannot be sensed, and there is only one type of connector.

[0006] Based on the above problems, there is a need for an inflatable boat inflation device with dual inflation connections to improve upon the aforementioned shortcomings. Utility Model Content

[0007] The main purpose of this utility model is to provide an inflatable boat inflation device with dual inflatable connections, but with a fixed length and is not convenient for telescopic inflation or simultaneous inflation of multiple inflatable boats.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A rubber boat inflation device with dual inflation connections includes a high-pressure gas cylinder connection pipe for connecting to a high-pressure gas cylinder.

[0010] An extension tube is installed at the outer end of the high-pressure gas cylinder connecting pipe, and a high-pressure gas cylinder valve is installed at one end of the high-pressure gas cylinder connecting pipe. An extension tube with a modified interface is installed at the outer end of the extension tube and the high-pressure gas cylinder connecting pipe. A pressure gauge and a modified connecting pipe are installed at the outer end of the modified extension tube. An inflator for the rubber boat and a connecting pipe are installed at the outer end of the pressure gauge and the modified connecting pipe.

[0011] Preferably, one end of the inflatable boat inflation head and connecting pipe is equipped with an inflatable boat inflation nozzle adapter, and the other end of the inflatable boat inflation head and connecting pipe is equipped with a fast-charging male connector. The extension air pipe of the modified interface has a spiral telescopic structure, and the size of the fast-charging male connector is 8mm.

[0012] Preferably, the inflatable boat inflation head, connecting pipe, pressure gauge, and modified connecting pipe are fixedly connected by a fast-charging male connector inserted into a fast-charging female connector, and the fast-charging female connector has a size of 8mm.

[0013] Preferably, a high-pressure air pump spray gun is installed at the outer end of the pressure gauge and the modified connecting pipe, and a mechanical pointer air pressure gauge is installed on the high-pressure air pump spray gun.

[0014] Preferably, the lower section of the high-pressure air pump spray gun is equipped with a male connector, which is fixedly connected to the extension air pipe of the modified interface, and an air gun switch is squeezed and installed on the high-pressure air pump spray gun.

[0015] Preferably, the outer end of the extension tube of the modified interface is equipped with a male connector 2, which is fixedly connected to the extension tube and the high-pressure gas cylinder connection tube.

[0016] The beneficial technical effects of this utility model are as follows:

[0017] This utility model provides an inflatable boat inflation device with dual inflation connections. This application adds an air inlet, enabling inflation using a truck's own air tank, or alternatively, connecting to a high-pressure gas cylinder. A pressure gauge is added to monitor the inflation pressure inside the inflatable boat in real time, ensuring pressure balance across all air chambers and avoiding reliance on intuition to judge pressure, which can lead to uneven pressure affecting the overall posture and safety of the inflatable boat. The device allows for two inflation methods: First, the inflatable boat inflation head can be connected to a connecting pipe, pressure gauge, and a modified connecting pipe and extension pipe, allowing connection to a modified high-pressure gas tank on a truck. Second, the inflatable boat inflation head can be simultaneously connected to a high-pressure gas cylinder, allowing for inflation and pressure monitoring, ensuring pressure balance across all air chambers.

[0026] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0027] Example

[0028] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, this embodiment provides an inflatable boat inflation device with dual inflation connections. The outer end of the high-pressure gas cylinder connecting pipe 5 is equipped with an extension pipe and a high-pressure gas cylinder connecting pipe 4. One end of the high-pressure gas cylinder connecting pipe 5 is equipped with a high-pressure gas cylinder valve 501. The outer end of the extension pipe and the high-pressure gas cylinder connecting pipe 4 is equipped with a modified interface extension pipe 3. The outer end of the modified interface extension pipe 3 is equipped with a pressure gauge and a modified connecting pipe 2. The outer end of the pressure gauge and the modified connecting pipe 2 is equipped with an inflatable boat inflation head and a connecting pipe 1.

[0029] One end of the inflatable boat inflation head and connecting pipe 1 is equipped with an inflatable boat inflation nozzle adapter 101, and the other end of the inflatable boat inflation head and connecting pipe 1 is equipped with a fast charging male connector 102. The extension air pipe 3 of the modified interface has a spiral telescopic structure, and the size of the fast charging male connector 102 is 8mm.

[0030] The inflatable boat inflation head, connecting pipe 1, pressure gauge, and modified connecting pipe 2 are fixedly connected by fast charging male connector 102 inserted into fast charging female connector 204. The fast charging female connector 204 has a size of 8mm.

[0031] The pressure gauge and the modified connecting pipe 2 are equipped with a high-pressure air pump spray gun 201 at their outer ends, and a mechanical pointer air pressure gauge 202 is installed on the high-pressure air pump spray gun 201.

[0032] The lower section of the high-pressure air pump spray gun 201 is equipped with a male connector 205, which is fixedly connected to the extension air pipe 3 of the modified interface. An air gun switch 203 is squeezed and installed on the high-pressure air pump spray gun 201.

[0033] The outer end of the extension tube 3 of the modified interface is equipped with a male connector 301, which is fixedly connected to the extension tube and the high-pressure gas cylinder connection tube 4.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, first check that all parts are intact and free from damage or leaks. Pay special attention to whether the air pipe interface, valve, and pressure gauge are normal. Confirm that the inflatable boat air nozzle and the inflatable boat air nozzle adapter 101 are compatible. Clean the debris at the interface. Select the corresponding connection scheme according to the air source. Prepare the truck air tank conversion interface or high-pressure air cylinder.

[0035] Insert the quick-charge male connector 102 of the inflatable boat inflation head and connecting pipe 1 into the pressure gauge and the quick-charge female connector 204 of the modified connecting pipe 2, ensuring an accurate 8mm size match and fixing it in place. Connect the pressure gauge and the male connector 205 of the modified connecting pipe 2 to the extension air pipe 3 of the modified interface. Stretch the spiral telescopic air pipe to the appropriate length according to the inflation distance. Connect the male connector 301 of the extension air pipe 3 of the modified interface to the truck air tank modification interface and tighten it to fix it.

[0036] Connect the inflator adapter 101 to the inflator nozzle, ensuring a tight seal. Turn on the air supply switch of the truck's air tank and press the air gun switch 203 to start inflation. Monitor the pressure in real time using the mechanical pointer pressure gauge 202, ensuring consistent pressure in each air chamber. Once the appropriate pressure is reached, first release the air gun switch 203, then turn off the truck's air tank switch. Disconnect the inflator, air hose, and inflation source in sequence, and retract the spiral telescopic air hose for storage.

[0037] Insert the quick-charge male connector 102 of the inflatable boat inflation head and connecting pipe 1 into the pressure gauge and the quick-charge female connector 204 of the modified connecting pipe 2, ensuring an accurate 8mm size match and fixing it in place. Connect the pressure gauge and the male connector 205 of the modified connecting pipe 2 to the extension air pipe 3 of the modified interface. Stretch the spiral telescopic air pipe to the appropriate length according to the inflation distance. Connect the male connector 301 of the extension air pipe 3 of the modified interface to the truck air tank modification interface and tighten it to fix it. Connect the inflatable boat inflation nozzle adapter 101 to the inflatable boat inflation nozzle, ensuring a tight seal and no air leakage. Connect one end of the extension pipe to the male connector 301 of the extension air pipe 3 of the modified interface, and fix the other end to the high-pressure gas cylinder connecting pipe 5, ensuring a tight seal at the interface.

[0038] Connect the high-pressure gas cylinder connecting pipe 5 to the high-pressure gas cylinder, tighten the interface, and confirm that the high-pressure gas cylinder valve 501 is in the closed state. Slowly open the high-pressure gas cylinder valve 501, press the air gun switch 203 to start inflation, and continuously observe the mechanical pointer air pressure gauge 202 to avoid excessive pressure or uneven pressure in each airbag. After reaching the specified pressure, first close the high-pressure gas cylinder valve 501, press the air gun switch 203 to release the residual gas in the pipe, and then release the air gun switch 203. Disconnect the rubber boat, each connecting air pipe, and the high-pressure gas cylinder in sequence, and organize and store the parts.

[0039] This application adds an air inlet to enable inflation using the truck's own air tank, or it can replace the air inlet to connect to a high-pressure air cylinder for inflation. It also adds a mechanical pointer air pressure gauge 202 to monitor the inflation pressure inside the inflatable boat in real time, so as to achieve pressure balance in each air chamber of the inflatable boat and avoid relying on experience to judge the pressure, thus avoiding uneven pressure in each air chamber, which can easily affect the overall posture and safety of the inflatable boat.

[0040] The system allows for two methods of inflating the inflatable boat. Inflating can be achieved by connecting the inflatable boat inflation head 1 to the connecting pipe 2, pressure gauge, and the modified connecting pipe 2 and the extended air pipe 3 of the modified interface. This allows connection to the interface of a modified high-pressure gas cylinder on a large truck. Alternatively, inflation can be achieved by simultaneously connecting the inflatable boat inflation head to the connecting pipe 1, pressure gauge, and the modified connecting pipe 2, the extended air pipe 3 of the modified interface, the extended pipe to the high-pressure gas cylinder connecting pipe 4, and the high-pressure gas cylinder connecting pipe 5. This allows connection to a high-pressure gas cylinder for inflation and also allows for monitoring of the inflatable boat's inflation pressure, ensuring balanced pressure across all air bladders.

[0041] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
