Abstract

The utility model relates to a buoyancy knapsack suitable for water surface movement and water operation. The buoyancy knapsack comprises a bag body composed of foamed buoyancy material and air bags, the bag body is provided with a partition, and is closed through a waterproof zipper. The bottom of the bag body is filled with foamed buoyancy material to provide fixed buoyancy; the air bags at the upper part of the bag body provide additional buoyancy. The knapsack provides total buoyancy of no more than 10 kg, which is suitable for the buoyancy requirement of water surface movement. The knapsack is provided with detachable ropes, which can be fixed to the shoulders or waists of users, and the knapsack can be changed into a floating bag for use on open water surfaces or in open water areas after the ropes are detached, and has a water surface rescue function. In addition, the knapsack has the characteristics of storing personal articles, waterproofing and buoyancy support, and is suitable for use in water surface movement, fishery operation and swimming.

Description

Technical Field

[0001] This utility model relates to the field of water sports and safety rescue equipment, and in particular to a buoyancy bag suitable for water sports and water operations. It can also be used as a water rescue tool for outdoor swimmers, fishermen and aquaculture farmers. Background Technology

[0002] Currently, there are no products on the market that combine a crossbody backpack / waist pack with a rescue flotation device (a "follower"). Existing waist packs or backpacks are typically only used for storing personal belongings, while flotation devices are mainly used for water rescue and are suitable for open water or beach resorts. In water sports such as dragon boating, canoeing, kayaking, and paddleboarding, traditional life jackets restrict mobility and affect performance; similarly, life jackets limit the freedom of movement for fishermen and aquaculture farmers during their water operations. Therefore, the market needs a device that combines storage and buoyancy rescue functions to meet safety requirements in multiple scenarios. Utility Model Content

[0003] To address the aforementioned technical problems, this invention provides the following technical solution:

[0004] This utility model buoyancy shoulder bag includes a bag body composed of foamed buoyancy material and an air bladder. The foamed buoyancy material fills the bottom of the bag body to provide fixed buoyancy; the air bladder is located in the upper part of the bag body and provides additional buoyancy by inflation. The bag body is equipped with a waterproof zipper and has an internal compartment for storing personal items such as mobile phones and keys.

[0005] Preferably, the foamed buoyancy material has a volume of 3-5 liters, providing a fixed buoyancy of no more than 5 kg; the airbag is inflated through the inflation valve, providing less than 5 liters of air buoyancy. The total buoyancy of the bag does not exceed 10 kg, which is sufficient to meet the needs of water sports.

[0006] Preferably, the shoulder bag is equipped with a detachable rope. After the rope is removed, the shoulder bag can be converted into a floatation bladder for use on the wild water surface or in open water, making it suitable for water rescue.

[0007] Preferably, the buoyancy bag is worn on the user's shoulder or waist with an adjustable shoulder strap, which can be adjusted to the back or chest for easy operation.

[0008] By adopting the above technical solution, the beneficial effects of this utility model are:

[0009] 1. A stylish backpack with storage function, waterproof and rainproof, and easy to carry, suitable for water sports, swimming, and production operations.

[0010] 2. Provides lightweight rescue buoyancy for water sports, swimming, and production operations, replacing bulky life jackets without affecting activities.

[0011] 3. Provides detachable floats suitable for swimming in the wild and fishing operations, enhancing safety in water activities. Attached Figure Description

[0016] The foamed buoyancy material used in this invention is a high-molecular thermoplastic material. This type of material is lightweight, waterproof, corrosion-resistant, and easy to mold, making it suitable for buoyancy structures of waterborne equipment.

[0017] Please refer to Figure 1-2 This utility model's buoyancy shoulder bag includes a bag body composed of foamed buoyancy material and an air bladder. The foamed buoyancy material fills the bottom of the bag body, providing fixed buoyancy; the air bladder is located in the upper part of the bag body, providing additional buoyancy. The bag body is closed with a waterproof zipper, and an internal compartment is used to store personal items. The buoyancy shoulder bag consists of two parts: the bottom is filled with 3-5 liters of foamed buoyancy material, providing fixed buoyancy of no more than 5 kg; the upper part is an inflatable air bladder, providing less than 5 liters of air buoyancy; the two parts together provide no more than 10 kg of buoyancy. A pocket space is separated inside the air bladder by a waterproof zipper for storing personal items such as keys and mobile phones, making it a shoulder bag that combines storage, waterproofing, and buoyancy support functions.

[0018] Please refer to Figure 3-4 The shoulder bag is equipped with a detachable rope that can be secured to the user's shoulder or waist. When the rope is removed, the shoulder bag can be transformed into a rescue tool that can replace a floatation bladder, meeting the rescue needs of wild waters and open waters.

[0019] Although the present invention has been described in conjunction with preferred embodiments, those skilled in the art should understand that various modifications in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such modifications shall fall within the protection scope of the present invention.
