Description

Technical Field

[0001] The invention belongs to the technical field of lifesaving, and in particular relates to an anti-drowning lifesaving backpack. Background Art

[0002] Drowning incidents among primary and secondary school students occur from time to time. In recent years, the country has continuously strengthened publicity and education, but there are still many tragedies of student drowning every year. In addition, tourists who go out for travel or leisure also fall into the water and drown. According to incomplete statistics, nearly 10,000 people drown in China every year. The current anti-drowning equipment mainly includes life jackets and high-pressure nitrogen cylinder inflatable airbags. Life jackets are large and cannot be carried by students and tourists. High-pressure nitrogen cylinder inflatable airbags are small and can be inflated by puncturing the cylinder when falling into the water, but there is a risk of explosion and they cannot be carried with you. Summary of the invention

[0003] In order to solve the deficiencies of the prior art, the present invention aims to provide a drowning prevention and life-saving backpack that can be carried around for drowning prevention and life-saving.

[0004] The drowning prevention and life-saving backpack of the present invention comprises a backpack and a buoyancy sheet, wherein an L-shaped pocket is arranged at the bottom of the backpack, the flat side of the L-shaped pocket is located at the lower bottom surface of the backpack, and the straight side of the L-shaped pocket is located at the front or back of the backpack, and the buoyancy sheet is inserted in the L-shaped pocket, and the buoyancy sheet comprises a buoyancy material and a waterproof cloth wrapped around the outside of the buoyancy material, and straps for being put on the arms are arranged on the left and right sides of the buoyancy sheet, and the buoyancy material can be a sponge sheet, a pearl cotton sheet, or a foam plastic sheet, and the pearl cotton sheet is preferably used.

[0005] Furthermore, a strap for hanging on the shoulder is arranged at the upper end of the buoyancy sheet, so that the lifesaving cushion can be more reliably maintained in front of the human chest, and is more reliable and safe when used.

[0006] Furthermore, the straps on the left and right sides of the buoyancy sheet are connected by a buckle, and each strap is provided with an arm swimming ring, which has two functions. First, after falling into the water, the arm swimming ring can be inflated with the mouth to increase the buoyancy, which is safer and more reliable. Second, before swimming, especially before swimming, the buckle can be opened, the arm swimming ring can be removed from the strap, and it can be put on the arm to inflate, so as to ensure the safety of swimming, especially the safety when swimming in the wild.

[0007] As another technical solution under the same concept of the present invention, the drowning rescue backpack includes a backpack and a buoyancy sheet. An L-shaped pocket is provided on the bottom of the backpack, and the flat edge of the L-shaped pocket is located on the lower bottom surface of the backpack. The buoyancy sheet is inserted into the LL-shaped pocket. The buoyancy sheet includes a buoyancy material and a waterproof cloth wrapped around the outside of the buoyancy material. A strap for hanging on the shoulder is provided on the upper end of the buoyancy sheet. When in use, you only need to hang the strap on your shoulder and hold the lifesaving cushion with both hands to prevent drowning and save lives.

[0008] The drowning prevention and life-saving backpack of the present invention is used as follows: it is usually used as a backpack, such as a school bag and a travel backpack. When falling into water accidentally, the buoyancy sheet is taken out of the backpack, and the arms are put into the shoulder straps on both sides or the hanging straps are hung on the shoulders. When both the shoulder straps on both sides and the hanging straps are provided, the hanging straps can be hung on the shoulders first, and then the arms are put into the shoulder straps on both sides, and the buoyancy sheet is held in front of the chest with both hands to generate life-saving buoyancy, thereby realizing drowning prevention and life-saving.

[0009] The anti-drowning life-saving backpack of the present invention comprises a backpack and a buoyancy sheet. An L-shaped pocket is arranged at the bottom of the backpack, the flat edge of the L-shaped pocket is located at the lower bottom surface of the backpack, the buoyancy sheet is inserted in the LL-shaped pocket, the buoyancy sheet comprises a buoyancy material and a waterproof cloth wrapped around the outside of the buoyancy material, the left and right sides of the buoyancy sheet are provided with straps for being put on the arms or the upper part is provided with a lanyard for being hung on the shoulders, the life-saving buoyancy sheet is cleverly integrated into the backpack, and the thickness of the bottom surface of the backpack is only increased or decreased by about 3 cm. A pocket with a thickness of 3 cm and a height of about 12 cm is added to the front or back of the backpack, so that the pocket can be taken out and put on the arm or hung on the shoulder when accidentally falling into the water, and the pocket is integrated with the backpack, which is convenient to carry and use and can be taken out in less than 2 seconds, thereby realizing anti-drowning life-saving and effectively reducing the occurrence of drowning accidents.

Implementation

[0027] Figures 1 to 8 The first embodiment of a drowning prevention lifesaving backpack of the present invention is shown, comprising a backpack 1 and a buoyancy sheet 3. An L-shaped pocket 2 is provided at the bottom of the backpack 1, the flat side of the L-shaped pocket 2 is located at the lower bottom surface of the backpack 1, and the straight side of the L-shaped pocket 2 is located at the front or back of the backpack 1. The buoyancy sheet 3 is inserted into the L-shaped pocket 3. The buoyancy sheet 3 comprises a flat buoyancy sheet 31 and a straight buoyancy sheet 32. A soft connecting section 33 is provided between the flat buoyancy sheet 31 and the straight buoyancy sheet 32 ​​for easy bending and unfolding. The buoyancy material of the flat buoyancy sheet 31 is an pearl cotton sheet M36, and the buoyancy material of the straight buoyancy sheet 32 ​​is an pearl cotton sheet M37. The pearl cotton sheets M36 and M37 are wrapped with waterproof cloth 38 on the outside, and the soft connecting section 33 is also made of waterproof cloth 38. A left shoulder strap 34 for wearing on the arm is provided on the left side of the buoyancy sheet 3, and a right shoulder strap 35 for wearing on the arm is provided on the right side.

[0028] Figures 9 to 12The figure shows a buoyancy sheet used in a second embodiment of an anti-drowning lifesaving backpack of the present invention. The difference between the second embodiment and the first embodiment is the buoyancy sheet 3. The left shoulder strap 34 and the right shoulder strap 35 of the buoyancy sheet 3 of the second embodiment are connected by plugging and unplugging with buckles, and an arm swimming ring 39 is respectively mounted on the left shoulder strap 34 and the right shoulder strap 35.

[0029] Fig.13 The buoyancy sheet used in the third embodiment of the drowning prevention lifesaving backpack of the present invention is shown. The difference between the third embodiment and the second embodiment lies in the buoyancy sheet 3. The upper end of the buoyancy sheet 3 of the third embodiment is equipped with a shoulder strap 40.

[0030] Fig.14 and Fig.15 This is a real picture of the buoyancy sheet used in the present invention. After application tests in swimming pools, the buoyancy sheet is easy and reliable to wear, and the buoyancy provided is sufficient for an adult to float on his back on the water surface and breathe safely. When floating on the water surface, the arm swimming ring can be inflated to increase the buoyancy after inflation, so that the posture in the water can be more free and the wave resistance is stronger.
