Multifunctional waterproof backpack

Technical Field

The utility model relates to a case and bag class technical field especially relates to a multi-functional waterproof knapsack.

Background

At present, people go out to conveniently carry articles, and all use backpacks, such as computer bags, schoolbag, satchel and the like. In the prior art, common backpacks are only used for accommodating articles, the accommodating capacity of the backpacks is limited, and the backpacks are carried by shoulders, and if the articles in the backpacks are heavy, the user is easy to fatigue when carrying the backpacks for a long time. Simultaneously, when carrying out outdoor exercises, if the condition that falls into water appears, the timely effectual rescue in scene is often not enough, and because the mode that current knapsack mostly adopted the zip fastener seals, the leakproofness is not enough, not only can not provide help to the person that falls into water after falling into the aquatic, still can cause the burden to the person that falls into water.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a simple structure is provided, can not only enlarge the capacity of knapsack, can also provide better sealed, realizes falling into water lifesaving function's multi-functional waterproof knapsack.

The utility model provides an above-mentioned technical problem's technical scheme as follows: a multifunctional waterproof backpack comprises a backpack body and shoulder straps, wherein the backpack body is made of waterproof cloth outside, the shoulder straps are arranged on the backpack body, an extending portion extending upwards is arranged at the top of the backpack body, the bottom of the extending portion is fixedly connected with the top of the backpack body in an integrated manner, the bottom of the extending portion is communicated with the inside of the backpack body, and an opening is formed in the top of the extending portion; the two sides of the opening at the top of the extension part are respectively and fixedly provided with a first inserting buckle and a second inserting buckle which are mutually buckled through a connecting belt, and the top of the extension part can be folded to seal the opening to realize the sealing of the inner space of the backpack body.

The utility model has the advantages that: set up the extension at the top of knapsack body, can not only increase the capacity of knapsack body through the setting of extension, realize its open-top's sealed through the folding of self simultaneously, improve holistic leakproofness, realize open-ended sealed through the lock joint of first eye-splice and second eye-splice after folding sealed, after the user falls into water, can play the effect of interim life buoy.

On the basis of the technical scheme, the utility model discloses can also do following improvement.

Further, the extension part is of a cylindrical structure made of the same material as the backpack body.

Further, the both sides of knapsack body are put up respectively through connecting band fixedly connected with be used for with the third eye-splice of first eye-splice lock joint and be used for with the fourth eye-splice of second eye-splice lock joint, the third eye-splice with first eye-splice is located same one side of knapsack body, the fourth eye-splice with the second eye-splice is located same one side of knapsack body.

The beneficial effect of adopting the further scheme is that: through setting up third eye-splice and fourth eye-splice, with first eye-splice and third eye-splice lock joint, different connected mode is realized to second eye-splice and fourth eye-splice lock joint, when receiving more article in knapsack body and the extension, still can make things convenient for the fixed at extension top.

Further, the bottom of knapsack body is equipped with a plurality of gyro wheels.

The beneficial effect of adopting the further scheme is that: the arrangement of the rollers can facilitate the dragging and moving of the backpack.

Further, the bottom of knapsack body is equipped with and is used for holding the holding tank of gyro wheel, be equipped with the mount pad in the holding tank, the gyro wheel is installed on the mount pad.

The beneficial effect of adopting the further scheme is that: the setting of holding tank can avoid the gyro wheel too protruding knapsack body.

Further, the one end of mount pad with the inner wall of holding tank is articulated, the other end of mount pad with the inner wall joint of holding tank.

The beneficial effect of adopting the further scheme is that: when the roller is not used, the roller and the mounting seat are rotated into the accommodating groove, so that the roller is prevented from leaking; when the roller is needed, the mounting seat is turned out.

Further, the bottom in the knapsack body is fixedly provided with a placement plate for reinforcing, and the holding tank is arranged on the placement plate.

The beneficial effect of adopting the further scheme is that: the setting of arrangement board can improve the intensity of knapsack body bottom, because the weight of knapsack and its inside article leads to the gyro wheel to be absorbed in the knapsack body and can't use when avoiding using the gyro wheel.
