Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Example

[0041] See also Figure 1-Figure 10, the utility model provides the following technical solutions: a multi-purpose backpack, comprising a backpack body 1, a large containing mechanism 2 and a small containing mechanism 3;

[0042] The backpack body 1 is a double-shoulder type, and the large storage mechanism 2 is set in the middle of the backpack body 1;

[0043] The small storage mechanism 3 is arranged on the back of the backpack body 1;

[0044] The backpack body 1 includes a backpack bag 11, a zipper 12 for tightening and stretching is provided at the middle of the top of the backpack bag 11, a hand strap 13 is provided at the top of the bag body of the backpack bag 11, a bag placement 14 is provided on the side of the zipper 12, and a large storage mechanism 2 is also provided on the back of the backpack bag 11.

[0045] In this embodiment, a receiving cavity is provided on the other side of the backpack bag 11 , a side bag 141 is provided in the middle of the side wall of the backpack bag 11 , and a lock buckle 15 is provided on the belt surface of the side bag 141 .

[0046] The backpack bag 11 and the zipper 12 are used for people to put articles into the storage cavity when traveling outdoors. In addition, the side bag 141 and the lock buckle 15 cooperate with each other to lock and fine-tune.

[0047] In this embodiment: a backpack strap 16 is installed on the back of the backpack bag 11, and the backpack straps 16 are symmetrically sewn on both sides of the backpack bag 11. An inner diameter adjustment buckle 17 is provided in the middle of the bottom end of the backpack strap 16, and a tightening belt 18 for binding and tightening is provided in the middle of the inner diameter adjustment buckle 17.

[0048] The adopted backpack strap 16 and the specific inner diameter adjustment buckle 17 play the role of allowing the backpack strap 16 to be carried on the body by the personnel, and the tightening belt 18 shares the weight of the backpack itself.

[0049] In this embodiment: the other end of the tightening belt 18 is sewn to the bottom side of the backpack bag 11, and the large accommodating mechanism 2 is arranged at the bottom of the back side of the backpack bag 11, including a sewn fabric interlayer 21 sewn to the bottom side of the backpack bag 11, and a slot 22 is opened on the side of the sewn fabric interlayer 21, and a side wall zipper 23 for sealing is sewn on the surface of the slot 22.

[0050] The stitched fabric interlayer 21 is used to reserve a corresponding space, which can be used as a storage place for the small backpack 31, and cooperate with the expansion of the internal space capacity of the large backpack to achieve dual-purpose.

[0051] In this embodiment: a chain 24 is provided at the linking end of the side wall zipper 23, and a small accommodation mechanism 3 for expanding the carrying capacity is embedded and coated inside the side wall zipper 23;

[0052] And the small storage mechanism 3 includes a small backpack 31 embedded inside the stitched fabric sandwich 21;

[0053] The small backpack 31 is square in shape and fits snugly into the space inside the stitched fabric interlayer 21 .

[0054] The adopted small backpack and the designated stitched fabric interlayer 21 can be taken as a separate backpack, and the separate small backpack 31 can be unzipped until it is combined with the inner carrying fabric bag 361 to form a complete fabric surface.

[0055] In this embodiment: a circle of zipper assembly 32 is sewn on the edge of the small backpack 31, and the surface of the zipper assembly 32 is bound with an edge tightening nylon belt 33 for tightening, and the middle part of the edge tightening nylon belt 33 is provided with a disassembly buckle 34, and the surface of the disassembly buckle 34 is provided with an elastic card block 35 for fastening.

[0056] The zipper assembly 32 and the corresponding disassembly buckle 34 are used to reduce the volume of the small backpack 31. In addition, the elastic block 35 is used as a strap to fix the pad when the entire zipper of the small backpack 31 is opened, so that it can serve as a temporary hammock outdoors.

[0057] In this embodiment: the locking end of the elastic block 35 is engaged with the elastic connecting seat at the lower end, one end of the elastic connecting seat is clamped with the surface of the corresponding edge tightening nylon belt 33, and an independent inner carrying cloth bag 361 for expanding the storage is provided in the middle of the small backpack 31.

[0058] The advantage of using the small backpack 31 and the inner carrying cloth bag 361 is that the internal toughness of the small backpack 31 is expanded. At the same time, after unfolding, the cloth area can greatly exceed the area of ​​the backpack 31, and can be used for other purposes.

[0059] In this embodiment: the seams between the inner carrying cloth bag 361 and the small backpack 31 are detachable and assembled by sewing and chaining;

[0060] The inner carrying cloth bag 361 has a size that is consistent with that of the small backpack 31 , and is inserted into the small backpack 31 through a zipper on the edge of the small backpack 31 .

[0061] By adopting the inner carrying cloth bag 361, an extra-large cloth surface is expanded, and the combination is sewn and linked, which can be disassembled and washed later and used separately.

[0062] In this embodiment, the edge of the small backpack 31 can be stored by sewing a circle of zippers, and expanded into a square pad.

[0063] A large square piece of fabric can be used as a makeshift hammock without having to worry about its toughness.

[0064] In this embodiment: elastic band tightening grooves 311 for tightening are sewn at the four corners of the small backpack 31, and the tightening nylon belts 33 are arranged in the corresponding elastic band tightening grooves 311. The four sides of the small backpack 31 are extended by the edge tightening nylon belts 33, and a composite zipper 312 is sewn on one side of the small backpack 31, and one end of the composite zipper 312 is sewn and connected to the side wall of the side bag 141.

[0065] The main purpose is to provide the small backpack 31 with dual-purpose features. One is that it can be used as a picnic mat after being unfolded, because the edge composite zipper 312 can be sewn with the inner wall of the side pocket 141, which makes it convenient to insert it into the side pocket 141 to increase the softness of the backrest. In addition, the composite zipper 312 and some structures can be used as a small mobile changing room, which can be folded and placed in the side pocket 141 when not in use, thereby alleviating the supporting pressure of the backpack body 1 on the back of the person.

[0066] Step 1: Act as a normal backpack container for storing items:

[0067] Application range: As a school bag or a long-distance travel backpack;

[0068] A person only needs to unzip the zipper 12 to show the cavity that serves as the basic storage function of the backpack. In this way, a portion of the items can be unzipped first to show the placement opening, and the items can be directly placed in the opening position above the opened backpack bag 11 to use it as an ordinary backpack. When a person travels a long distance, he can either hold the backpack body 1 at the position of the hand strap 13 or carry it on his shoulders using the backpack straps 16 on both sides;

[0069] In addition to this, the second advantageous step is that when storing a conventional backpack, an additional chamber for storing items is sewn near the back of the backpack pouch 11. The large storage mechanism 2 can be used in conjunction with the sewn fabric interlayer 21 as a storage for embedded backpack items. The personnel open the side wall of the independent large storage mechanism 2 and sew the upper side wall zipper 23 separately to show the internal space, which can be used in conjunction with the small backpack 31, or the independent internal space can be used as other storage. In addition, the personnel can also take out the back side set inside the sewn fabric interlayer 21, and then the user unfastens it according to the edge of the small backpack 31, unzips the zipper assembly 32, and then uses the link assembly to unfasten it directly according to the corresponding small backpack 31 to unfasten the internal space. At this time, the user needs to press the specified elastic card block 35 and let the two independent edges tighten the nylon belts 33 loosen, so that the small backpack 31 can be smoothly unfolded;

[0070] This small backpack 31 has two uses. One is to directly unfasten the zipper assembly 32 arranged around the backpack 31, so that the entire backpack 31 can be directly expanded into a cushion cloth for people to lay on, or when there is no extra cloth bag outdoors and a hammock needs to be built, the nylon belt 33 can be tightened at the edge to directly use it as an outdoor hammock. Of course, the bearing capacity of the hammock is also based on the toughness standard of the material of the nylon belt 33 tightened at the edge;

[0071] The second use is to roll up the extra inner carrying cloth bag 361 directly after unfolding, and then there is still a part of space to directly place items in the entire small backpack 31, so that it can be used as a small backpack 31 for storing items;

[0072] In addition, when the dust-proof mat does not need to be unfolded, the personnel can directly remove a small portion of the inner carrying bag 361 and put the items in it, which can also achieve the purpose of one bag for multiple uses;

[0073] This makes it more convenient to store when traveling.

[0074] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
