Description

Anti-theft backpack

Technical field

The utility model relates to knapsack technical field, espespecially a kind of anti-theft backpack.

Background technique

Knapsack is and easy to carry due to that can place large numbers of items, has become people and goes on a journey outside a kind of indispensable object Product are liked by the majority of consumers.Current knapsack pocket is all to make backpack body switch freely, user using zip closure Just.But there is also security risks when in use for existing knapsack, since knapsack is worn on the back, the sight of people has no idea to infuse It anticipates to behind, especially in bus, subway, the more place of people, is difficult to perceive back knapsack situation, so can usually give Criminal is with opportunity, since the pulling-on piece that the zipper on knapsack need to only be held on pull head can be closed or opened, he Can open knapsack easily, valuables are stolen, so that user is largely lost.Therefore, occur on the market anti- Packet is stolen, but there is also many problems when in use for existing anti-theft pack, such as：1. common knapsack is mostly the materials such as cloth, leather Matter, it is too easy to be damaged although easily molded, more attractive, when outgoing with knapsack placement valuables, the back of common material Packet is easy to realize theft by destroying backpack body by tools such as burglar's blades；2. go out to take a seat, knapsack is easy suitable by thief It walks or is taken by mistake by other passengers.

Summary of the invention

To solve the above problems, the utility model provides a kind of anti-theft backpack, anti-theft performance is good, safe and convenient to use.

To achieve the above object, the technical solution adopted in the utility model is to provide a kind of anti-theft backpack, including knapsack sheet Body and anti-theft chain, the knapsack ontology are three-decker, from outside to inside respectively outer layer, steel wire interlayer, internal layer, described anti- Stealing chain includes coded lock and chain, and the coded lock includes that lock body and latch hook, one end of the chain are fixedly connected on lock body Tail portion, the other end then connect with latch hook, and outgoing when taking a seat, knapsack ontology is fixedly connected by anti-theft chain with fixture.

Wherein, the outer layer is wear-resistant fabric.

Wherein, the internal layer is highly dense nylon cloth.

Wherein, the chain is elastic iron chains.

It wherein, further include the two-way resealable zipper being arranged at knapsack body openings, the two-way resealable zipper includes two A knob, when walking, anti-theft chain connects two knobs of two-way resealable zipper.

The beneficial effects of the utility model are：

Compared to existing anti-theft backpack, the utility model is by increasing steel between the internal layer and outer layer of knapsack ontology Silk screen interlayer even if thief cuts open fabric with blade, but due to the protection of steel wire interlayer, can effectively prevent thief and stretch out one's hand Enter to take property and avoid falling for property, thief in society can be efficiently solved and scratch the problem of knapsack is committed theft；It is carrying on the back Packet ontology increases anti-theft chain, when going out to take a seat, can be locked knapsack on not easily shifted fixture by anti-theft chain, It need not just be in constant fear of and be coated with along walking when chatting in this way with friend client, effectively solve to be placed on knapsack in outdoor and is neglected by the side of Slightly, the case where causing knapsack to be taken away by thief.

Drawing reference numeral explanation：1- knapsack ontology；2- anti-theft chain；The two-way resealable zipper of 3-；11- outer layer；12- steel wire every Layer；13- internal layer；21- coded lock；22- chain；31- knob.

Specific embodiment

The utility model is described in detail with Figure of description combined with specific embodiments below.

Please refer to shown in Fig. 1-3, the utility model about a kind of anti-theft backpack, including knapsack ontology 1 and anti-theft chain 2, The knapsack ontology 1 is three-decker, from outside to inside respectively outer layer 11, steel wire interlayer 12, internal layer 13, the anti-theft chain 2 include coded lock 21 and chain 22, and the coded lock 21 includes that lock body and latch hook, one end of the chain 22 are fixedly connected on lock The tail portion of body, the other end are then connect with latch hook, and when going out to take a seat, knapsack ontology 1 connects by the way that anti-theft chain 2 and fixture are fixed It connects.

Compared to existing anti-theft backpack, the utility model between the internal layer 13 and outer layer 11 of knapsack ontology 1 by increasing Steel wire interlayer 12 is added, even if thief cuts open fabric with blade, but due to the protection of steel wire interlayer 12, can effectively prevent Only thief, which stretches out one's hand into, takes property and avoids falling for property, can efficiently solve thief in society and scratch what knapsack was committed theft Problem；Anti-theft chain 2 is increased in knapsack ontology 1, when going out to take a seat, knapsack can be locked by anti-theft chain 2 and be not easy to move On dynamic fixture, it need not just be in constant fear of and be coated with along walking when chatting in this way with friend client, effectively be solved knapsack in outdoor The case where being placed on and be ignored by the side of, knapsack is caused to be taken away by thief.

In the present embodiment, the outer layer 11 is wear-resistant fabric.

Using the above scheme, so that knapsack outer surface is more wear-resistant, practicability and aesthetics are stronger.

In the present embodiment, the internal layer 13 is highly dense nylon cloth.

Using the above scheme, inside backpacks toughness is enhanced, and nylon cloth is wear-resisting, waterproof.

In the present embodiment, the chain 22 is elastic iron chains.

Using the above scheme, chain 22 can be elongated, increases the range used.

It further include the two-way resealable zipper 3 that 1 opening of knapsack ontology is set in the present embodiment, the two-way sealing is drawn Chain 3 includes two knobs 31, and when walking, anti-theft chain 2 is by two knobs, 31 connection of two-way resealable zipper 3.

Using the above scheme, the knob 31 of the two-way resealable zipper 3 of knapsack ontology 1 is connected to one by anti-theft chain 2 It rises, it is inevitable also to pull anti-theft chain 2 when direct pull handle, so that so that knapsack people is found someone at once is opening packet, thus Play antitheft effect.

Embodiment of above is only that preferred embodiments of the present invention are described, not to the utility model Range be defined, under the premise of not departing from the spirit of the design of the utility model, this field ordinary engineering and technical personnel to this The various changes and improvements that the technical solution of utility model is made should all fall into the guarantor that claims of the utility model determine It protects in range.
