[0002] A backpack refers to a bag carried on the back, and its materials are diverse, including genuine leather, plastic, polyester, canvas, nylon, cotton and linen and other textures of luggage. In the era of increasingly advocating individuality, various styles such as simplicity, retro, and cartoon also meet the needs of fashionable people to show their individuality from different aspects. The styles of luggage have also expanded from traditional business bags, schoolbags, and travel bags to pen cases, coin purses, small sachets, etc.

[0003] In order to improve the load-reducing effect, a waist buckle belt is generally set on a load-reducing backpack. When climbing a mountain or trekking for a long time, the load-reducing backpack is fixed to the waist. When the load-reducing backpack is used daily and the waist buckle belt is not needed, the waist buckle belt hangs on the side of the backpack and sways on the side of the backpack as it moves, which will affect the use of the backpack. Content of the Utility Model

Specific embodiments

[0023] The following further elaborates on the present utility model in conjunction with the attached drawings.

[0024] Embodiment:

[0025] Referring to Figures 1-5 , a load-reducing backpack with a hidden waistband disclosed by the present utility model includes a load-reducing backpack main body 1 and a backpack lid 2 fixedly connected to the upper end thereof. One side of the load-reducing backpack main body 1 is fixedly connected with a backpack shoulder strap 3. Two storage grooves 17 are opened in the load-reducing backpack main body 1, and a shrinking groove 21 is opened on one side wall of the storage groove 17. A waist elastic belt 11 is fixedly connected to one side wall of the storage groove 17;

[0026] A second connecting block 23 and a first connecting block 12 are respectively fixedly connected to the two waist elastic belts 11. A connecting card slot 22 is opened on one side wall of the second connecting block 23, and a moving groove 14 is opened on one side of the first connecting block 12. Two L-shaped clamping blocks 13 are slidably arranged between the side walls of the moving groove 14;

[0027] Two hidden pockets 5 are fixedly connected to one side of the load-reducing backpack main body 1, and a rubber band 19 is fixedly connected to one side of each of the two hidden pockets 5.

[0028] In this embodiment, the load-reducing backpack body 1 can be carried on the back through the backpack straps 3. Pull the two waist elastic bands 11 outwards. The waist elastic bands 11 are arranged in the storage groove 17, but one end of each of them extends out of the load-reducing backpack body 1 from the contraction groove 21. The two waist elastic bands 11 can be fixedly tied around the waist. When the waist elastic bands 11 are released, due to their own elastic recovery, the first connection block 12 and the second connection block 23 can be stuck at the notch of the contraction groove 21. When the hidden bag 5 is pulled, the rubber band 19 is in a compressed state. The second connection block 23 is inserted into the hidden bag 5. When the rubber band 19 is released, the rubber band 19 contracts due to its elasticity, and the second connection block 23 can be hidden in the hidden bag 5, so that the belt part can be hidden, improving the practicability. Preferably, if the waist elastic band (11) is long, it can also be contracted into the hidden bag 5. The hidden bag 5 fits the load-reducing backpack body 1 and has the same color.

[0029] Further, specifically refer to Figure 3 There is a moving member between the L-shaped block 13 and the first connection block 12. The moving member includes a bidirectional lead screw 15. The bidirectional lead screw 15 is rotatably connected between the inner top wall and the inner bottom wall of the moving groove 14. Both L-shaped blocks 13 are threadedly connected to the circumferential side of the bidirectional lead screw 15 through screw nuts.

[0030] In this embodiment, the L-shaped block 13 is inserted into the connection card slot 22, and the bidirectional lead screw 15 is rotated. The L-shaped block 13 moves up and down on the circumferential side of the bidirectional lead screw 15. One of the two L-shaped blocks 13 moves up and the other moves down. The shorter end of the L-shaped block 13 is inserted into the notches on both the upper and lower sides of the connection card slot 22, so as to realize the connection between the first connection block 12 and the second connection block 23, and the two waist elastic bands 11 can be tied around the waist.

[0031] Further, specifically refer to Figure 2 and Figure 3 Two limiting rods 16 are fixedly connected between the inner top wall and the inner bottom wall of the moving groove 14. Both L-shaped blocks 13 are slidably connected to the circumferential sides of the two limiting rods 16.

[0032] In this embodiment, the L-shaped block 13 slides on the circumferential side of the limiting rod 16 and can move up and down along with the limiting rod 16, improving the moving stability of the L-shaped block 13.

[0033] Further, specifically refer to Figure 5 A shrinkage prevention block 18 is fixedly connected between the side walls of the contraction groove 21. A shrinkage prevention card slot 20 is opened on one side of the shrinkage prevention block 18. The waist elastic band 11 is located in the shrinkage prevention card slot 20.

[0034] In this embodiment, the size of the anti-shrinkage card slot 20 opened on the anti-shrinkage block 18 is larger than the waist elastic band 11 and smaller than the first connection block 12 and the second connection block 23. When the waist elastic band 11 elastically returns, the waist elastic band 11 can shrink into the storage groove 17, and the first connection block 12 and the second connection block 23 are located outside the load-reducing backpack body 1.

[0035] Further, for details, please refer to Figure 1 and Figure 4 A third reinforcement band 9 is fixedly connected to the circumferential side of the load-reducing backpack body 1. A connecting band 6 is fixedly connected to one side of the load-reducing backpack body 1. Two second reinforcement bands 8 are fixedly connected to the lower end of the connecting band 6, and both of the two second reinforcement bands 8 are fixed to the third reinforcement band 9.

[0036] In this embodiment, the side reinforcement band 10 and the second reinforcement band 8 can support the bottom of the backpack, making it more convenient to carry on the back.

[0037] Further, for details, please refer to Figure 1 On both upper sides of the backpack shoulder strap 3, widened bands 4 are fixedly connected. Two first reinforcement bands 7 are fixedly connected to one side of the load-reducing backpack body 1, and the first reinforcement bands 7 are connected to the third reinforcement band 9.

[0038] In this embodiment, the widened bands 4 can increase the width of the backpack shoulder strap 3. When carrying on the back, it can increase the contact area of the shoulder, thereby improving the feeling when carrying.

[0039] The implementation principle of the above embodiment is as follows: Through the backpack shoulder strap 3, the load-reducing backpack body 1 can be carried on the body. Pull the two waist elastic bands 11 outwards. The waist elastic bands 11 are arranged in the storage groove 17, but one end of each of them extends out of the load-reducing backpack body 1 from the contraction groove 21, and the two waist elastic bands 11 can be fixedly tied around the waist. When the waist elastic bands 11 are released, due to their own elastic return, the first connection block 12 and the second connection block 23 can be stuck at the notch of the contraction groove 21. Pull the hidden bag 5, and the rubber band 19 is in a compressed state. Then, the second connection block 23 is stuffed into the hidden bag 5. When the rubber band 19 is released, the rubber band 19 shrinks due to its elasticity, and the second connection block 23 can be hidden in the hidden bag 5, so that the belt part can be hidden, improving the practicality.

[0040] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0041] The embodiments of this specific implementation manner are all the preferred embodiments of the present invention. Without restricting the protection scope of the present invention accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
