Description

Rainproof knapsack

Technical Field

The utility model relates to the technical field of backpacks, in particular to a rainproof backpack.

Background

Leather backpacks are commonly used in everyday work and study at ordinary times. However, in rainy days, the person who goes out is difficult to take the backpack into consideration, and the backpack is easy to be drenched by rain, so that the leather backpack is affected with damp. The leather backpack is formally neat in style and is not suitable for entertainment activities and traveling.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide a rainproof backpack which has the characteristics of simple structure and multiple purposes.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the rainproof backpack comprises a backpack body 1, wherein the backpack body 1 covers a whole piece of material 2 on the side surface and the upper surface when in use, the front surface of the material 2 is a leather surface, the back surface of the material 2 is made of TPU coating material, a first zipper 5 and a second zipper 6 are respectively arranged on the long edges of the material 2 in parallel, the first zipper 5 and the second zipper 6 are zippers on one side without a pull head, the first zipper 5 is connected with the backpack body 1, the second zipper 6 is connected with another piece of covering material 3, the backpack body 1 and the covering material 3 are zippers on one side with a pull head, and the covering material 3 is used for covering the front surface of the backpack body 1.

The material 2 is rectangular.

The covering material 3 is a TPU coating material.

The covering material 3 is connected with the bag body 1 by a third zipper 7.

The back of the bag body 1 is provided with a belt 4, and the belt 4 is used for accommodating the covering material 3.

The utility model has the beneficial effects that:

when the backpack is used in rainy and informal occasions, the upper covering surface is the reverse side TPU coating material surface, and the TPU coating material is zipped with the lower surface to close the backpack, so that the backpack can be suitable for more living occasions. When the leather covering surface is used in formal work and study occasions, the front leather covering surface is used as the upper covering surface, the original leather backpack can be decorated by the leather covering surface, and the lower TPU coating material is stored on the rear surface of the backpack. When replacing the two covering materials, the two zippers connected with the bag body can be opened, the two covering surfaces are detached from the bag body, and replacement, cleaning and airing are carried out.

Detailed Description

The present invention will be described in further detail with reference to examples.

As shown in fig. 1-4, a rainproof backpack comprises a backpack body 1; the bag body 1 and the covering material 3 are zippers with sliders, and the covering material 2 can be selected to use the front surface and the back surface according to the use requirement; the whole TPU coating material is connected with the lower edge of the back surface of the backpack and covers the lower surface and the front surface of the backpack when in use, and the bottom of the TPU coating material 3 is connected with the backpack body 1 by a zipper III 7; the two pieces of covering surface material are closed by a zipper I5. The back of the bag is provided with a belt 4 for containing a whole piece of covering material 3 below, and the lower part of the backpack strap is connected with the lower edge of the back side of the bag in order to be beneficial to containing TPU coating material.

The working principle of the utility model is as follows:

the two pieces are connected with the schoolbag by a zipper, and the covering surface of the schoolbag can be closed by the zipper. The bag has three states of use, namely, a state in which two TPU coating materials are combined for use (as shown in FIG. 2), a state in which the covering surface is accommodated in the back surface of the bag (as shown in FIG. 3), and a state in which the covering surface is completely detached (as shown in FIG. 4). When the two TPU coating materials are combined for use, the covering surface of the upper half part adopts a reverse TPU coating covering surface, the rear part of the covering surface is connected with the upper part and two sides of the rear surface of the schoolbag by a whole zipper II 6, the side surface and the upper surface of the schoolbag are annularly wrapped, and the front zipper I5 is used for being connected with the lower TPU coating material. One side of the lower whole piece of TPU coating material is connected with the lower edge of the rear surface of the schoolbag by a third zipper 7, and the other three sides are connected with the upper TPU coating material by a first zipper 5. When the schoolbag is used, the two covering surfaces can be connected through the first zipper 5, the TPU coating covering surfaces wrap the upper surface and the side surfaces of the schoolbag, and the TPU coating covering surfaces are turned forwards to wrap the lower surface and the front surface of the schoolbag, so that the outside of the schoolbag is sealed. When the leather covering surface is used, the upper half covering surface adopts a front leather covering surface, the lower whole TPU coating material is turned backwards and bypasses the rear part of the belt 4, and the TPU coating material is folded in half to be stored. When the covering surface is required to be changed or the schoolbag is cleaned and aired, the two covering materials are connected with the schoolbag by the zipper, the covering surface at the upper part can be detached by pulling the zipper II 6, and the TPU coating material at the lower part can be detached by pulling the zipper III 7.

The utility model can use the original leather surface of the backpack in more formal working occasions, and the rainproof TPU coating material surface which is contained on the schoolbag is covered on the schoolbag when raining. Besides, the TPU coating bag surface is more leisure, so that the backpack can be suitable for more living occasions, such as travel, entertainment activities and the like. The entertainment activity needs various fashionable bags and clothes, the TPU coating bag can be designed with various colors and patterns, and can be disassembled and replaced, and the change of various shapes and styles can be completed by one bag. The color of the backpack needs to be bright in color during travel to ensure the travel safety, and the TPU coating material can also meet the requirement. And the working part has two covered surfaces, one surface is made of TPU coating material, and the other surface is made of leather material. When the leather material surface is used, the patterns with various colors are formed, and the original leather backpack is decorated.
