Description

Freely extensible backpack

Technical Field

The utility model belongs to the technical field of case and bag, concretely relates to open fast and can increase knapsack capacity can freely the elongated knapsack.

Background

For the backpack for daily outing and traveling, the larger the required storage capacity is, the better the backpack is, and the larger the storage capacity is, the larger the backpack is, and when a plurality of backpack bodies do not contain enough articles, the whole backpack is not harmonious in free space, so that the whole attractiveness of the backpack is affected.

SUMMERY OF THE UTILITY MODEL

To the not enough of above technique existence, the utility model provides a knapsack that can freely the elongated type.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: can freely stretch out type's knapsack, including the knapsack body, the upper end of knapsack body is provided with the top, and the lower extreme is provided with the bottom, and the front side of knapsack body is provided with the opening zip fastener, and this opening zip fastener forms its characterized in that from the bottom until extending to the top setting: the top of the backpack body is an upward extending end; magnetic attraction guide grooves I are symmetrically sewn at the front side edge of the backpack body through length adjusting belts, and magnetic attraction guide grooves II are symmetrically sewn at the two side edges of the backpack body through the length adjusting belts; and the first magnetic attraction guide groove and the second magnetic attraction guide groove are mutually attracted in a magnetic way.

The extending end can be freely folded towards the front side direction of the backpack body.

The first magnetic attraction guide groove is provided with clamping concave points, and the second magnetic attraction guide groove is relatively provided with clamping convex points.

The magnetic attraction guide groove can be replaced by a movable buckle.

The utility model has the advantages that: compared with the prior art, the utility model discloses a be provided with the extension end back at the top in the upper end of knapsack body, can carry out the expansion of capacity, increase dilatation storing space, can store more article, reduce the capacity back when needs simultaneously, can fold the extension end, inhale the guide way one through magnetism after folding and inhale the guide way two inter attraction bundle group lock solid together with magnetism, make the knapsack whole more pleasing to the eye after the shrinkage is held.

Drawings

The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this application:

fig. 1 is the volume expansion state diagram of the backpack body of the present invention.

Fig. 2 is a shrinking state diagram of the backpack body of the present invention.

In the figure: 1. a backpack body; 2. a magnetic attraction guide groove I; 3. an extension end; 4. an open zipper.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-2, the backpack capable of being freely stretched comprises a backpack body 1, wherein a top is arranged at the upper end of the backpack body 1, a bottom is arranged at the lower end of the backpack body 1, an open zipper 4 is arranged at the front side of the backpack body 1, the open zippers 4 can be symmetrically arranged at two edges of the front side, the open zippers 4 are arranged from the bottom to the top, and articles can be conveniently placed when the zipper openings are enlarged. The top of the backpack body 1 is provided with an upward extending end 3, and the inner cavity of the extending end 3 is actually integrated with the inner cavity of the backpack body 1 to form an accommodating cavity of the backpack body; magnetic attraction guide grooves I2 are symmetrically sewn at the front side edge of the backpack body 1 through length adjusting belts, and magnetic attraction guide grooves II 4 are symmetrically sewn at the two side edges of the backpack body 1 through the length adjusting belts; and the magnetic attraction guide groove I2 and the magnetic attraction guide groove II 4 are mutually attracted in a magnetic way. When the extension end 3 is folded towards the front side of the backpack body 1, the first magnetic attraction guide groove 2 and the second magnetic attraction guide groove 4 attract each other to bind the extension end, so that the purpose of reducing the capacity is achieved.

When the bag content needs to be reduced, the extension end can be freely folded towards the front side direction of the backpack body, and when the bag content needs to be enlarged, the extension end 3 of the binding upper is loosened.

The magnetic attraction guide groove I2 is provided with a clamping concave point, and the magnetic attraction guide groove II 4 is relatively provided with a clamping convex point so that the magnetic attraction guide groove I2 and the magnetic attraction guide groove II 4 can be conveniently attracted and then buckled together.

The magnetic attraction guide groove can be replaced by a movable buckle.

The utility model discloses an after the extension end that sets up at the top, when needs enlarge the capacity, open bundle group and extend the end, the inner chamber that extends the end can make full use of, increases dilatation storing space length, stores more article. When the volume is required to be reduced, the extension end is folded and tied up through the magnetic attraction guide groove or after the movement, so that the whole backpack is more attractive.

The utility model discloses it is right to have used specific individual example the utility model discloses a principle and implementation have been elucidated, and the explanation of above embodiment is only used for helping understanding the utility model discloses a method and core thought thereof.
