Description

Technical Field

[0001] The present application relates to the technical field of backpacks, and in particular to an anti-fading backpack. Background Art

[0002] Backpack is a common daily necessity, which is widely used in daily life. It is usually composed of a bag body and a shoulder strap. A certain amount of items can be placed in the bag body, which provides convenience for our travel and outing.

[0003] Since people sometimes walk outdoors with backpacks on, a certain amount of ultraviolet rays will shine on the backpacks during the day, which will destroy the structure of the color-producing patterns on the backpack materials, causing color instability and the possibility of fading, which may affect the durability and aesthetics of the backpack, so further improvements are needed. Utility Model Content

[0004] In order to slow down the fading rate of the outer surface of a backpack under the influence of ultraviolet rays in the external sunlight, the present application provides an anti-fading backpack.

[0005] The present application provides an anti-fading backpack, which adopts the following technical solution:

[0006] A fade-resistant backpack comprises a backpack body with an inner cavity, the outer surface of the backpack body is coated with an anti-ultraviolet additive to form an anti-ultraviolet layer, the surface of the backpack body close to the back is provided with shoulder straps, the surfaces of the backpack body and the shoulder straps close to each other are both provided with an elastic layer, an adsorption layer arranged on the elastic layer for absorbing sweat, and a breathable layer arranged on the adsorption layer.

[0007] By adopting the above technical solution, an anti-ultraviolet additive is coated on the surface of the backpack body to form an anti-ultraviolet layer, so as to improve the impact of the backpack on the outdoor ultraviolet rays, thereby slowing down the rate of fading of the outer surface of the backpack under the influence of ultraviolet rays under the external sunlight. In addition, during the carrying process, the back of the backpack body and the surface close to the shoulder straps and shoulders in a relatively hot environment will produce a certain amount of sweat to soak into the back of the backpack body and the back of the shoulder straps. When placed outdoors, the sweat attached to the surface of the backpack body and the shoulder straps may fade after being exposed to external ultraviolet rays. Therefore, by providing an elastic layer, an adsorption layer and a breathable layer, during the carrying process, the vibration of walking can squeeze the elastic layer to drive the air flow between the breathable layer and the adsorption layer, so that the generated sweat can pass through the breathable layer to be retained at the adsorption layer, reducing the possibility of sweat being retained on the surface of the backpack body and the shoulder straps, thereby reducing the possibility of fading after being exposed to external ultraviolet rays.

[0008] Preferably, a diaphragm is bonded to the outer surface of the backpack body, and the anti-ultraviolet layer is arranged on the outer surface of the diaphragm away from the backpack body.

[0009] By adopting the above technical solution, the diaphragm is bonded, so that the anti-ultraviolet layer originally coated can be replaced when it is damaged, so as to extend the service life of the anti-ultraviolet layer of the backpack body and reduce the impact of the anti-ultraviolet layer on the anti-ultraviolet layer of the backpack body after being worn or failed. The diaphragm can also improve the protective effect of the backpack body.

[0010] Preferably, the backpack body has a cavity, and a bag opening connected to the cavity is opened on the outer surface of the backpack body. The backpack body is provided with two chain teeth for opening and closing the bag opening and a pull head for engaging or separating the two chain teeth. The backpack body is provided with a shielding belt for covering the chain teeth and the pull head at the bag opening, and the shielding belt is also provided with an anti-ultraviolet layer.

[0011] By adopting the above technical scheme, most of the chain teeth and pull heads in the prior art are made of plastic or metal. Among them, the chain teeth and pull heads made of plastic will fade and become brittle when exposed to external ultraviolet rays. Therefore, a shielding strip is provided to shield the chain teeth and pull heads made of plastic, which can reduce the possibility of external ultraviolet rays irradiating into the bag opening through the gaps between adjacent chain teeth, thereby reducing the possibility of objects in the backpack body being exposed to external ultraviolet rays.

[0012] Preferably, the bag opening includes a first bag opening arranged at the top of the backpack body and a second bag opening arranged on the surface of the backpack body away from the shoulder strap, and there are a plurality of the first bag openings and the second bag openings, and the cavities correspond to the first cavity and the second cavity respectively.

[0013] By adopting the above technical solution, the first bag opening and the second bag opening are provided, and the first cavity and the second cavity are provided correspondingly, so as to improve the space utilization effect in the backpack body.

[0014] Preferably, the backpack body is provided with side pockets on both sides thereof, side pocket openings are provided on the upper edges of the side pockets, elastic bands are wrapped around the side pocket openings of the backpack body, fixing parts for fixing items placed in the side pockets are provided above the side pockets of the backpack body, and mounting blocks for fixing the fixing parts are provided on the backpack body.

[0015] By adopting the above technical scheme, side pockets are provided, and elastic bands are provided on the side pocket openings so as to shrink the side pocket openings to a certain extent, thereby reducing the possibility of some items placed in the side pockets falling due to external shaking, and some items higher than the side pocket openings can be stabilized to a certain extent. However, for some items that are too high, due to their own weight, the elastic bands may be stretched too much, resulting in the possibility of slipping and falling, and the elastic bands may fail after being pulled. Therefore, fixings are provided above the side pockets to fix some items that are too high and reduce the possibility of falling.

[0016] Preferably, the fixing member comprises a magnetic block fixedly connected to the mounting block.

[0017] By adopting the above technical solution, some items that are too high, such as water cups, or some items that can be magnetically attracted to the magnetic block can be magnetically attracted to the magnetic block to improve the fixing effect of the items.

[0018] Preferably, the fixing component includes a fixing belt fixed to the mounting block, a mother Velcro arranged on the fixing belt, a child Velcro arranged on the free end of the fixing belt, and a ring for the fixing belt to pass through, the length direction of the mother Velcro is parallel to the length direction of the fixing belt, and the child Velcro is adhered to the mother Velcro.

[0019] By adopting the above technical solution, after the free end of the fixing belt is passed through the loop, the fixing belt is then tightened, and the child Velcro is adhered to the mother Velcro at the corresponding position to fix the item, thereby reducing the possibility of the item falling into the side pocket due to its own gravity.

[0020] Preferably, the fixing member is a cable tie fixedly connected to the mounting block, the cable tie is a snap-on cable tie, and the cable tie head of the cable tie is fixedly connected to the mounting block.

[0021] By adopting the above technical solution, items that are too high are placed in the side pocket, and then the free end of the snap tie is passed through the tie head. Due to the cooperation between the locking teeth provided on the tie and the locking teeth provided on the tie head, the items are fixed. Since the tie is a snap tie, it can be reused.

[0022] In summary, the utility model has the following beneficial effects:

[0023] By coating the surface of the backpack body with an anti-ultraviolet additive to form an anti-ultraviolet layer, the backpack is protected from the influence of external ultraviolet rays when carried outdoors, thereby slowing down the rate at which the outer surface of the backpack fades under the influence of ultraviolet rays under external sunlight. In addition, during the carrying process, the back of the backpack body and the surface close to the shoulder straps and shoulders will produce a certain amount of sweat to soak into the back of the backpack body and the back of the shoulder straps in a relatively hot environment. When placed outdoors, the sweat attached to the surface of the backpack body and the shoulder straps may fade after being exposed to external ultraviolet rays. Therefore, by providing an elastic layer, an adsorption layer and a breathable layer, during the carrying process, the vibration of walking can squeeze the elastic layer to drive the air flow between the breathable layer and the adsorption layer, so that the generated sweat can pass through the breathable layer and be retained at the adsorption layer, reducing the possibility of sweat being retained on the surface of the backpack body and the shoulder straps, thereby reducing the possibility of fading after being exposed to external ultraviolet rays.
