Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bags and suitcases, and particularly relates to a sealed waterproof backpack. BACKGROUND

[0002] A backpack is a portable equipment for carrying personal articles, usually in the form of a double-shoulder bag. The backpack is made of various materials, including leather, plastic, polyester, canvas, nylon, etc. The style and design are also various. The backpack not only provides the function of convenient carrying, but also meets the needs of different people through diversified design. The backpack is an indispensable accessory in people's daily life.

[0003] For outdoor backpacks, waterproof fabric is often used to improve the waterproof performance of the backpack. However, liquid can easily penetrate into the backpack through the gap between the zipper of the opening of the backpack, resulting in water seepage. Solving this technical problem will play a positive role in improving the waterproof performance of the backpack. SUMMARY

[0004] The utility model aims at providing a sealed waterproof backpack to solve the problems mentioned in the background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a backpack body, a flow guide groove, and a clamping strip are provided. An opening for accommodating articles is formed on the backpack body, and the opening can be closed by a zipper. A protruding part is formed on the backpack body outward along the opening. The flow guide groove is connected to the backpack body below the protruding part and on one side of the opening. The flow guide groove is distributed along the length direction of the protruding part, and the two ends of the flow guide groove are located outside the backpack body. The clamping strip is arranged in pairs. The clamping strip is connected to the backpack body below the protruding part. The clamping strip and the flow guide groove are located on both sides of the opening, and the clamping strip can clamp one side of the flow guide groove.

[0006] Preferably, the utility model further comprises a liquid silicone strip. The clamping strip is connected to the backpack body through the liquid silicone strip. The liquid silicone strip has good tensile elasticity and anti-aging property. The elasticity of the liquid silicone strip drives the clamping strip to clamp the flow guide groove.

[0007] Preferably, the utility model further comprises a fixed magnet strip and a movable magnet strip. The fixed magnet strip is located in the liquid silicone strip, and the movable magnet strip is located on one side of the flow guide groove. The movable magnet strip and the fixed magnet strip drive the clamping strip to clamp the flow guide groove. The fixed magnet strip and the movable magnet strip refer to a strip-shaped component made of a magnet or mainly made of a magnet.

[0008] Preferably, the top cross section of the clamped side of the flow guide groove is quadrangular, and the cross section of the contact end of the clamping strip and the flow guide groove is triangular. Such a structure design helps the flow guide groove to enter between the clamping strips and also helps the flow guide groove to leave between the clamping strips.

[0009] Compared with the prior art, the utility model has the advantages of the following:

[0010] The sealing waterproof backpack has the advantages of the following: BRIEF DESCRIPTION OF DRAWINGS

[0016] The technical solutions in the embodiments of the utility model will be apparently and completely described with reference to the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative work belong to the protection scope of the utility model.

[0017] EMBODIMENT

[0018] In combination with Figs. 1-3 A sealing waterproof backpack, which comprises a backpack body 1, a flow guide groove 2, a clamping strip 3, a liquid silicone rubber strip 4, a fixed magnet strip 5 and a movable magnet strip 6. The backpack body 1 is provided with an opening 101 for containing articles, and the opening 101 can be closed by a zipper.

[0019] The protruding part 201 is protruded outwardly from the opening 101 of the backpack body 1, the flow guide groove 2 is connected with the backpack body 1 at the side of the opening 101 below the protruding part 201, the flow guide groove 2 is distributed along the length direction of the protruding part 201 and the two ends of the flow guide groove 2 are located outside the backpack body 1, and the flow guide groove 2 is preferably made of thermoplastic TPU material.

[0020] The clamping strips 3 are arranged in pairs and connected with the backpack body 1 below the protruding part 201, the clamping strips 3 and the flow guide groove 2 are located at the two sides of the opening 101 respectively, the clamping strips 3 can clamp one side of the flow guide groove 2, the top cross section of the clamping side of the flow guide groove 2 is quadrangular, and the cross section of the contact end of the clamping strips 3 and the flow guide groove 2 is triangular.

[0021] The clamping strips 3 are connected with the backpack body 1 through the liquid silicone rubber strips 4.

[0022] The fixed magnet strips 5 are located in the liquid silicone rubber strips 4, the movable magnet strips 6 are located at one side of the flow guide groove 2, and the movable magnet strips 6 and the fixed magnet strips 5 drive the clamping strips 3 to clamp the flow guide groove 2.

[0023] The working principle of the utility model is as follows: when the opening 101 is closed, the fixed magnet strips 5 and the movable magnet strips 6 attract each other, one side of the flow guide groove 2 can be clamped into the clamping strips 3 and clamped by the clamping strips 3, and the flow guide groove 2 and the clamping strips 3 cooperate to form a compartment in the backpack body 1 which is connected with the external environment, when liquid enters the backpack body 1 from the opening 101, the liquid is blocked by the flow guide groove 2, then the liquid flows along the flow guide groove 2 and finally leaves from the two ends of the flow guide groove 2, so that the waterproof performance of the backpack body 1 can be improved to avoid liquid entering the inside of the backpack body 1 from the opening 101, when the opening 101 is opened, the liquid silicone rubber strips 4 are stretched and deformed due to the action of the user, so that the position of the clamping strips 3 is deviated, the flow guide groove 2 is separated from the clamping strips 3, and the opening and closing of the opening 101 is not affected.

[0024] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
