Description

Technical Field

[0001] The utility model relates to an inflatable life jacket with a tightening device, belonging to the field of lifesaving equipment. Background Art

[0002] An inflatable life jacket is a type of water life-saving equipment made of nylon fabric or neoprene, inflated with an inflation device, and uses buoyancy to give the wearer sufficient buoyancy to float on the water. The current inflatable life jacket is mainly composed of a sealed inflatable vest airbag, a gas generator (with a built-in gas generator) and a quick inflation valve.

[0003] Since life jackets are larger in size to fit most people, and a tightening device is installed on the front of the life jacket to facilitate wearing the life jacket more snugly, however, the airbag of the inflatable life jacket increases in volume when inflated. When the tightening device tightens the life jacket, it also squeezes the airbag, which can easily cause the life jacket to burst due to excessive force, reducing the safety and service life of the inflatable life jacket during tightening and adjustment.

[0004] In summary, the present invention provides an inflatable life jacket with a tightening device to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present invention aims to provide an inflatable life jacket with a tightening device to solve the problem that the air bag is squeezed when the inflatable life jacket is tightened.

[0006] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solutions: an inflatable life jacket with a tightening device, comprising a life vest and a zipper, wherein an upper air bag is fixedly connected between the shoulders, front chest and back of the life vest, the zipper is fixedly installed at the front seam of the life vest, two retractable waist belts are fixedly installed in sequence from top to bottom between the two sides of the front of the life vest and below the upper air bag, and a lower air bag is fixedly connected between the front and back of the life vest and below the retractable waist belt.

[0007] Furthermore, the bottoms of both sides of the front of the upper airbag are connected to a first air valve, and the bottoms of both sides of the front of the lower airbag are connected to a second air valve.

[0008] Furthermore, the retractable waist belt includes two mounting blocks respectively fixedly connected to both sides of the waist of the life vest, a fixing belt is embedded in the front of one mounting block, and an adjusting belt is fixedly connected to the front of the other mounting block, and a connecting ring is sleeved on the end of the fixing belt away from one mounting block, and one end of the adjusting belt passes through the back of the connecting ring and extends to the side of the front of the adjusting belt away from the connecting ring.

[0009] Furthermore, the adjustment strap is in a folded shape, and a Velcro hook surface is fixedly connected to the surface of the adjustment strap and one side located at the folded portion.

[0010] Furthermore, a Velcro surface is fixedly connected to the surface of the adjusting strap and the other side of the folded portion, and the folded portion of the adjusting strap is connected to the Velcro surface via a Velcro hook surface.

[0011] Furthermore, the connecting ring is in a square ring shape, and the adjusting belt is in contact with the connecting ring.

[0012] Furthermore, the ends of the fixing belt separated from the adjusting belt are fixedly connected to the front surfaces of the two mounting blocks respectively.

[0013] Beneficial effects of the utility model:

[0014] By tearing one end of the adjusting strap to release the adhesion between the hook surface of the Velcro and the fleece surface of the Velcro, then folding and pulling the adjusting strap, and pulling one end of the fixing strap through the connecting ring, the distance between the two mounting blocks can be shortened, and then the waist of the life vest can be tightened, and then the folded part of the adjusted adjusting strap can be adhered and fixed through the hook surface of the Velcro and the fleece surface of the Velcro. The operation is simple, and the inflatable life jacket can be quickly tightened and adjusted.

[0015] By installing two narrow elastic belts to shrink and adjust the waist of the life vest, the waist is evenly stressed. At the same time, the width of the adjustment belt and the fixing belt inside the elastic belt is reduced, making it easier to tear off the Velcro hook and Velcro fleece surface and unfold the folded part of the adjustment belt, making the tightening and adjustment of the inflatable life jacket more convenient and labor-saving.

[0016] The two elastic belts are located at the waist of the life vest. Tightening the life vest from the waist can avoid squeezing the chest cavity of the life vest wearer, making it easier to breathe in the water. When the life vest is tightened by the two elastic belts, the inflated upper and lower air bags will not be squeezed, avoiding the inflatable life vest from bursting, thereby improving the safety and service life of the inflatable life vest during tightening and adjustment.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-4 The utility model provides a technical solution: an inflatable life jacket with a tightening device, comprising a life jacket 1 and a zipper 2. An upper air bag 3 is fixedly connected between the shoulders, front chest and back of the life jacket 1. The zipper 2 is fixedly installed at the front seam of the life jacket 1. Two elastic waist belts 5 are fixedly installed from top to bottom between the two sides of the front of the life jacket 1 and below the upper air bag 3. A lower air bag 6 is fixedly connected between the front and back of the life jacket 1 and below the elastic waist belt 5. The two elastic waist belts 5 are located at the waist of the life jacket 1. Tightening the life jacket 1 from the waist can avoid damage to the life jacket. The compression of the wearer's chest makes it easier for the wearer to breathe in the water, and when the life vest 1 is tightened by the two elastic belts 5, the inflated upper air bag 3 and the lower air bag 6 will not be squeezed, thereby avoiding the situation that the inflatable life jacket will be squeezed and burst, thereby improving the safety and service life of the inflatable life jacket during tightening and adjustment. The bottoms of both sides of the front of the upper air bag 3 are connected to the first air valve 4, and both sides of the front of the lower air bag 6 are connected to the second air valve 7. By opening the two first air valves 4 on the front of the upper air bag 3, gas can be injected into the interior of the upper air bag 3, and by opening the two second air valves 7 on the front of the lower air bag 6, gas can be injected into the interior of the lower air bag 6.

[0025] See also Figure 2-4The elastic waist belt 5 includes two mounting blocks 51 which are respectively fixedly connected to both sides of the waist of the life vest 1. A fixing belt 52 is embedded in the front of one mounting block 51, and an adjusting belt 53 is fixedly connected to the front of the other mounting block 51. A connecting ring 54 is sleeved on the end of the fixing belt 52 away from one mounting block 51. One end of the adjusting belt 53 passes through the back of the connecting ring 54 and extends to the side of the front of the adjusting belt 53 away from the connecting ring 54. The adjusting belt 53 is folded. A Velcro hook surface 55 is fixedly connected to the surface of the adjusting belt 53 and one side of the fold. A Velcro hook surface 55 is fixedly connected to the surface of the adjusting belt 53 and the other side of the fold. The Velcro fleece surface 56 and the folded part of the adjusting belt 53 are connected to the Velcro fleece surface 56 through the Velcro hook surface 55. The connecting ring 54 is a square ring. The adjusting belt 53 is in contact with the connecting ring 54. The ends of the fixing belt 52 and the adjusting belt 53 that are separated are respectively fixedly connected to the front faces of the two mounting blocks 51. By installing two narrow elastic belts 5, the waist of the life vest 1 is contracted and adjusted, so that the waist is evenly stressed. At the same time, the width of the adjusting belt 53 and the fixing belt 52 inside the elastic belt 5 is reduced, making it easier to tear off the Velcro hook surface 55 and the Velcro fleece surface 56 to unfold the folded part of the adjusting belt 53.

[0026] Specific implementation: When the life vest 1 is worn, the two first air valves 4 on the front of the upper air bag 3 can be opened to fill the air inside the air bag 3, and the two second air valves 7 on the front of the lower air bag 6 can be opened to fill the air inside the lower air bag 6.

[0027] When the life jacket needs to be tightened and worn, one end of the adjusting strap 53 is torn to release the adhesion between the Velcro hook surface 55 and the Velcro fleece surface 56, and then the adjusting strap 53 is folded and pulled, and one end of the fixing strap 52 is pulled through the connecting ring 54, so as to shorten the distance between the two mounting blocks 51, and then the waist of the life jacket 1 can be tightened, and then the folded part of the adjusted adjusting strap 53 is adhered and fixed through the Velcro hook surface 55 and the Velcro fleece surface 56. The operation is simple, and the inflatable life jacket can be quickly tightened and adjusted.

[0028] By installing two narrow elastic belts 5 to shrink and adjust the waist of the life vest 1, the waist is evenly stressed. At the same time, the width of the adjusting belt 53 and the fixing belt 52 inside the elastic belt 5 is reduced, making it easier to tear off the Velcro hook surface 55 and the Velcro loop surface 56 and unfold the folded part of the adjusting belt 53, making the tightening and adjustment of the inflatable life jacket more convenient and labor-saving.

[0029] The two elastic belts 5 are located at the waist of the life vest 1. Tightening the life vest 1 from the waist can avoid squeezing the chest of the life vest wearer, making it easier to breathe in water. When the life vest 1 is tightened by the two elastic belts 5, the inflated upper air bag 3 and the lower air bag 6 will not be squeezed, thus avoiding the inflatable life jacket from being squeezed and bursting, thereby improving the safety and service life of the inflatable life jacket when tightening and adjusting.
