Description

Technical Field

[0001] This utility model belongs to the technical field of water safety and lifesaving equipment, specifically relating to a folding life jacket inflation device. Background Technology

[0002] As a crucial personal life-saving equipment for water use, life jackets have evolved from early buoyancy material filling to modern airbag-type automatic inflation technology. Folding life jackets, due to their small size and portability, are widely used in various scenarios such as maritime operations, water sports, aviation navigation, and daily boat crossings. Their inflation devices typically use high-pressure gas cylinders as the air source, relying on water pressure or manual triggering mechanisms to achieve rapid inflation, aiming to provide users with life safety protection in emergency situations.

[0003] Traditional folding life jacket inflation devices generally suffer from several problems, including insufficient trigger reliability (especially in complex aquatic environments where water-sensitive elements may fail or trigger falsely), difficulty in balancing inflation speed and gas release stability leading to slow or incomplete airbag deployment, poor structural integration and sealing design of the high-pressure gas cylinder and triggering mechanism resulting in chronic air leakage or the risk of false activation due to accidental impact, and insufficient optimization of overall size and weight affecting the portability and wearing comfort of the life jacket. These issues directly impact its rescue performance and user safety in emergency situations. Therefore, a folding life jacket inflation device has been developed. Utility Model Content

[0025] Example

[0026] Reference Figures 1-4 This is an embodiment of the present invention, which provides a folding life jacket inflation device, comprising:

[0027] The gas canister 101, the inflation body 102 connected to the surface of the gas canister 101 via threads, the fixing plate 103 fixedly installed on the inner wall of the inflation body 102, the shaft plate 104 disposed in the inner cavity of the inflation body 102, the gas outlet assembly 105 connected to the inner wall of the gas canister 101 via threads, the pressing assembly 106 fixedly installed on the inner wall of the fixing plate 103, the pulling assembly 107 fixedly connected to the shaft center of the shaft plate 104, and the pushing assembly 108 fixedly installed on the surface of the inflation body 102.

[0028] The gas outlet assembly 105 includes a bolt 105a threadedly connected to the inner wall of the gas cylinder 101, a sealing ring 105b adapted to be installed on the surface of the bolt 105a, a directional plate 105c slidably connected to the inner wall of the bolt 105a, a push rod 105d welded to the inner wall of the directional plate 105c, a sealing plate 105e fixedly installed at the end of the push rod 105d, and a first spring 105f disposed in the inner cavity of the bolt 105a.

[0029] Among them, the push rod 105d presses the first spring 105f through the directional plate 105c, and the sealing plate 105e opens to achieve the air release effect. The first spring 105f pushes the directional plate 105c, and the directional plate 105c drives the push rod 105d to achieve the sealing of the air outlet 106b by the sealing plate 105e to prevent air leakage.

[0030] Specifically, the pressing component 106 includes an airflow channel 106a that is snapped onto the surface of the bolt 105a, an air outlet 106b that is opened on the outer wall of the airflow channel 106a, a limiting plate 106c that is slidably connected to the inner wall of the airflow channel 106a, a punch 106d that is welded to the inner wall of the limiting plate 106c, and a second spring 106e that is disposed in the inner cavity of the airflow channel 106a.

[0031] Among them, the punch 106d pushes the push rod 105d, and the gas flows through the airflow channel 106a to the air outlet 106b. The second spring 106e pushes the limiting plate 106c, and the limiting plate 106c drives the punch 106d to rise, thereby resetting the punch 106d and closing the sealing plate 105e.

[0032] Furthermore, the pulling assembly 107 includes a slide block 107a slidably connected to the inner wall of the shaft plate 104, a slide rod 107b slidably connected to the inner wall of the slide block 107a, a pull rod 107c movably connected to the surface of the slide rod 107b, a pull block 107d movably connected to the top of the pull rod 107c, a pull rope 107e fixedly connected to the surface of the pull block 107d, and a handle 107f fixedly installed at the top of the pull rope 107e.

[0033] The middle part of the pull rod 107c is movably connected to the axis of the shaft plate 104. Pulling the handle 107f causes the handle 107f to pull one end of the pull rod 107c via the pull rope 107e. The middle part of the pull rod 107c rotates at the axis of the shaft plate 104. The other end of the pull rod 107c reciprocates on the inner wall of the slide block 107a via the slide rod 107b. The pull rod 107c causes the slide block 107a to move up and down via the slide rod 107b. The slide block 107a presses the punch 106d, causing the punch 106d to press down.

[0034] Preferably, the actuating assembly 108 includes a threaded opening 108a fixedly installed on the surface of the inflatable body 102, a mounting barrel 108b threadedly connected to the surface of the threaded opening 108a, a water-soluble sheet 108c disposed on the inner wall of the threaded opening 108a, a third spring 108d disposed in the inner cavity of the mounting barrel 108b, and a pressure rod 108e slidably connected to the inner wall of the mounting barrel 108b.

[0035] It should be noted that the surface of the mounting bucket 108b is provided with a water inlet. Water flows through the water inlet to the water-soluble sheet 108c. When the water-soluble sheet 108c disappears, the third spring 108d pushes the pressure rod 108e, and the pressure rod 108e pushes the sliding block 107a, so that the life jacket automatically inflates when it comes into contact with water.

[0036] In use, the surface of the mounting bucket 108b has a water inlet. Water flows through the inlet to the water-soluble plate 108c. When the water-soluble plate 108c disappears, the third spring 108d pushes the pressure rod 108e, which in turn pushes the sliding block 107a, causing the life jacket to automatically inflate upon contact with water. Pulling the handle 107f causes it to pull one end of the pull rod 107c via the pull rope 107e. The middle of the pull rod 107c rotates at the axis of the shaft plate 104. The other end of the pull rod 107c reciprocates against the inner wall of the sliding block 107a via the slide rod 107b. The pull rod 107c, through the slide rod 107b, causes the sliding block 107a to move up and down. The slot block 107a presses down the punch 106d, causing the punch 106d to press down. The punch 106d pushes the push rod 105d, and the gas flows through the airflow channel 106a to the air outlet 106b. The second spring 106e pushes the limiting plate 106c, and the limiting plate 106c drives the punch 106d to rise, realizing the reset of the punch 106d and closing the sealing plate 105e. The push rod 105d presses the first spring 105f through the directional plate 105c, and the sealing plate 105e opens to realize the gas outlet effect. The first spring 105f pushes the directional plate 105c, and the directional plate 105c drives the push rod 105d, realizing the sealing plate 105e to seal the air outlet 106b to prevent gas leakage.

[0037] In summary, the cooperation between the air outlet component 105 and the pressure component enables automatic inflation of the life jacket; the cooperation between the push component 108 and the pressure component enables automatic inflation in water; the cooperation between the pull component 107 and the pressure component enables manual inflation of the life jacket; and the cooperation between the first spring 105f and the push rod 105d enables re-inflation of the used air tank 101. The device is simple and efficient to operate, effectively solving the problems of traditional inflation devices where the air tank 101 cannot be reused after use, resulting in resource waste.
